 WHEREAS, Plaintiffs, the United States of America (United States), on behalf of the United
States Environmental Protection Agency (EPA), and the Florida Department of Environmental Protection (FDEP), which is the agency of the State of Florida to which the Florida Legislature has delegated the exclusive power and duty to enforce Chapter
403, Florida Statutes, including the authority to bring actions in courts of competent jurisdiction for violations of the Florida Resource Recovery and Management Act pursuant to §§ 403.121, 403.131, 403.161, 403.708, and 403.727(2),
Florida Statutes (together the Plaintiffs), have filed a complaint alleging that Defendant Mosaic Fertilizer, LLC (Mosaic) has violated the Resource Conservation and Recovery Act (RCRA), 42 United States Code (U.S.C.) § 6901 et
seq., and the Florida Resource Recovery and Management Act, § 403.702 et seq., Florida Statutes (F.S.), and the applicable regulations in 40 C.F.R. Parts 260-270, and in
Chapter 62-730, Florida Administrative Code (F.A.C.) at its sulfuric acid, phosphoric acid and fertilizer manufacturing facilities located in Florida (Facilities); 

WHEREAS, the Complaint includes allegations that Mosaic failed to characterize and illegally treated, stored and disposed of hazardous
wastes from various processes at its Facilities, including: the production of sulfuric acid, diammonium phosphate (DAP) and monoammonium phosphate (MAP) fertilizer, and fluorosilicic acid (FSA); wastes generated during cleaning of the phosphoric
acid plant and fertilizer plant equipment; and wastewaters generated from the scrubbers used to control air pollution from the phosphoric acid plants and from other chemical and waste management processes at its Facilities without a RCRA permit or
interim status. The Complaint also alleges that Mosaic illegally placed hazardous wastes in a Phosphogypsum Stack System dedicated for managing phosphoric acid production wastes

Table of Contents

 
exempt from hazardous waste regulation pursuant to the Bevill Exemption, 40 C.F.R. § 261.4(b)(7), thus violating Sections 3004 and 3005 of RCRA, 42 U.S.C. §§ 6924-25, and the
applicable regulations in 40 C.F.R. Parts 260-270, and Sections 403.721 and 403.722, F.S, and the applicable regulations in Chapter 62-730, F.A.C., and that those
hazardous wastes remain in the Phosphogypsum Stack System; 
 WHEREAS, Mosaic denies the applicability of Subtitle C of RCRA and the
regulations promulgated thereunder to certain practices at the Mosaic Facilities that are the subject of the Complaint, denies the violations alleged in the Complaint, and maintains that it has been and remains in compliance with RCRA and is not
liable for civil penalties or injunctive relief; 
 WHEREAS, the objective of the Parties in this Consent Decree is to resolve the
civil claims alleged in the Complaint by 1) establishing certain injunctive relief and environmental projects, whereby Mosaic shall modify certain operating practices with respect to its management of hazardous wastes and Bevill-Exempt Wastes,
implement environmental controls, remediation, and financial assurance, and undertake certain pollution reduction and other beneficial projects; and 2) assessing an appropriate penalty; 

WHEREAS, Mosaic has conducted itself in good faith in its discussions with the Plaintiffs concerning the violations alleged in the
Complaint, and has already implemented certain operational changes at its Facilities and remedial measures, obviating the need for certain injunctive relief; 

WHEREAS, by agreeing to entry of this Consent Decree, Mosaic makes no admission of law or fact with respect to the allegations in the
Complaint, and continues to deny any non-compliance or violation of any law or regulation identified therein or in this Consent Decree. For the purpose of avoiding litigation among the Parties, however, Mosaic
and where

applicable its parent company, The Mosaic Company, agree to the requirements of this Consent Decree; 

WHEREAS, the Parties agree that the United States’ filing of the Complaint and entry into this Consent Decree constitute diligent
prosecution by the United States and FDEP, under Section 7002(b)(1)(B) of RCRA, 42 U.S.C. § 6972(b)(1)(B), of all matters alleged in the Complaint and addressed by this Consent Decree through the date of lodging of this Consent Decree; and

 WHEREAS, the Parties recognize, and the Court by entering this Consent Decree finds, that this Consent Decree has been negotiated
by the Parties in good faith and will avoid litigation among the Parties and that this Consent Decree is fair, reasonable, and in the public interest. 

NOW, THEREFORE, before the taking of any testimony, without the adjudication or admission of any issue of fact or law except as
provided in Section I (Jurisdiction and Venue), below, and with the consent of the Parties, 
 IT IS HEREBY ADJUDGED, ORDERED, AND
DECREED as follows: 
 I.  JURISDICTION AND VENUE 

1.        This Court has jurisdiction over the subject matter of this action and over the Parties,
pursuant to Section 3008(a) of RCRA, 42 U.S.C. § 6928(a), and 28 U.S.C. §§ 1331, 1332, 1345, 1355 and 1367. Venue is proper in this judicial district pursuant to 28 U.S.C. §§ 1331, 1332, 1345, 1355, 1367,
1391(b) and (c), and 1395(a), and Section 3008(a) and (g) of RCRA, 42 U.S.C. § 6928(a) and (g), because Mosaic’s Facilities are located in this judicial district. For purposes of this Consent Decree, or any action
to enforce this Consent Decree, the Parties consent to the Court’s jurisdiction over this Consent Decree and any such action and over Mosaic and The Mosaic Company, and further consent to venue in this judicial district.

 2.        Pursuant to Section 3008(a)(2) of RCRA, 42
U.S.C. § 6928(a)(2), notice of the commencement of this action has been given to FDEP. 

3.        For purposes of this Consent Decree only, Mosaic agrees that the Complaint states claims
upon which relief may be granted pursuant to Sections 3004 and 3005 of RCRA, 42 U.S.C. §§ 6924 and 6925, and Sections 403.721, 403.722, and 403.727, F.S. 

II.  APPLICABILITY 

4.        The obligations of this Consent Decree apply to and are binding upon the United States,
FDEP, Mosaic, and, as provided herein, The Mosaic Company, and any successors, assigns, or other entities or persons otherwise bound by law. Rights granted to EPA under this Consent Decree may be exercised by FDEP upon the written agreement of EPA
and FDEP with notice to Mosaic. Nothing in this Consent Decree shall apply to administrative or enforcement proceedings other than this action or an action to enforce this Consent Decree. Nor does anything in this Consent Decree relieve Mosaic of
its obligation to comply with any federal and state laws applicable to activities that are not within the definition of Work in this Consent Decree. 

5.        No transfer of ownership or operation of all or a portion of a Facility, whether in
compliance with the procedures of this Paragraph or otherwise, shall relieve Mosaic of its obligation to ensure that the terms of this Consent Decree are implemented, unless: (1) the transferee agrees in writing to undertake the obligations
required by this Consent Decree and to be substituted for Mosaic as a Party to the Consent Decree and thus be bound by the terms thereof; and (2) the United States, after consultation with FDEP, consents in writing to relieve Mosaic and the
Mosaic Company of their respective obligations under this Consent Decree pursuant to Section XVIII of this Consent Decree (Modification). At least thirty (30) Days prior

Table of Contents

 
to a proposed transfer of Mosaic’s obligations under this Consent Decree, or such other period agreed to by the Parties in writing: (i) Mosaic shall provide a copy of this Consent
Decree to the proposed transferee, if not previously provided; and (ii) shall provide written notice of the prospective transfer, together with a copy of the proposed written agreement (subject to Paragraphs 88 and 89 of this Consent Decree and
as may otherwise be agreed in writing) transferring obligations to the transferee, to EPA, FDEP, the United States Attorney for the Middle District of Florida, and the United States Department of Justice, in accordance with Section XV (Notices) of
this Consent Decree, together with a request for approval. The United States’ decision whether to approve the transferee’s substitution for Mosaic under this Consent Decree, and what conditions may attend approval, will take into
account: (i) the status of the projects in Appendix 6 (RCRA Compliance Schedule), (ii) whether the transferee has or will have prior to the transfer the financial and technical capability to comply with this Consent Decree, (iii) and
other factors that may be deemed relevant, including but not limited to the environmental compliance history of the proposed transferee and environmental management capabilities of the proposed transferee. As set forth in Appendix 2, Paragraph
36, any such transfer will not include the Financial Assurance obligations specified for Mosaic therein, and therefore will include Financial Assurance conditions appropriate to the transferee. Any transfer of ownership or operation of all or a
portion of the Facility without complying with this Paragraph constitutes a violation of this Consent Decree. The United States’ refusal to approve, or approval with conditions for, the substitution of the transferee for Mosaic under this
Consent Decree shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of this Consent Decree, but any judicial review shall be conducted pursuant to Paragraph 70(a) of this

  
 – 7 – 

Table of Contents

 
Consent Decree. If Mosaic does not prevail in such judicial review, Mosaic shall pay all costs incurred by the United States in connection with such judicial review, including
attorney’s fees. 
 6.        Mosaic shall: (1) provide a copy of this Consent Decree to
its President/CEO, Executive Vice Presidents, Senior Environmental Counsel, and the General Manager, Environmental Manager, and Maintenance Manager of each Facility, and shall ensure that any employees and contractors whose duties might reasonably
include compliance with any provision of this Consent Decree are made aware of this Consent Decree and specifically aware of the requirements of this Consent Decree that fall within such person’s duties; (2) place an electronic version of
the Consent Decree on its internal environmental website; and (3) post notice of lodging of the Consent Decree and its availability in a location at each Facility where legal notices are posted. Mosaic shall be responsible for ensuring that all
employees and contractors involved in performing any Work pursuant to this Consent Decree perform such Work in compliance with the requirements of this Consent Decree. 

7.        In any action to enforce this Consent Decree, Mosaic shall not raise as a defense the
failure by any of its officers, directors, employees, agents, or contractors to take any actions necessary to comply with the provisions of this Consent Decree. 

III.  DEFINITIONS

Corrective Action Work for the benefit of EPA pursuant to Appendix 2, Section IV. To the extent that Mosaic establishes Financial Assurances that includes a cash deposit in a Trust Fund for the benefit of EPA and FDEP, under this paragraph pursuant
to the requirements of Appendix 2, FDEP agrees such Trust Fund shall be a cash deposit arrangement under s. 403.4155(3)(b), F.S., for each of the Facilities in accordance with and with respect to the full amounts as specified under Schedule A of the
Trust Agreement to be established hereunder. EPA and FDEP agree that Mosaic and FDEP intend to enter into a separate FDEP Alternate Procedure Order pursuant to Rule 62 673.310, F.A.C., or an equivalent state order, that will further address
Mosaic’s obligations under Chapter 62-673, F.A.C., with respect to the Phosphogypsum Stack Systems at the Facilities, and at other facilities owned or operated by Mosaic in Florida, and such Alternate Procedure Order shall not reduce or
increase the Financial Assurances established hereunder. Mosaic’s inability to secure and/or maintain adequate Financial Assurance shall in no way excuse performance of the Work or any other requirement of this Consent Decree.

 26.      In addition to the financial assurance information
included in the reports required pursuant to Section VIII (Reporting Requirements) of this Consent Decree, Mosaic or The Mosaic Company as guarantor shall provide to EPA and FDEP, upon request, any information or reports that Plaintiffs are
authorized to request pursuant to Section 3007 of RCRA, 40 C.F.R. Part 264, Subpart H, Rule 62-730.180 F.A.C., or any other applicable statutory or regulatory information-gathering authorities, regarding
the financial status of Mosaic or The Mosaic Company as guarantor, the financial mechanism(s) provided by Mosaic or the Mosaic Company as guarantor to meet its obligation for Financial Assurance, and the financial institution or guarantor providing
the financial mechanism(s) to secure Mosaic’s or The Mosaic Company’s obligations, pursuant to Appendix 2. 

27.      EPA Review of Submissions.  All work plans, reports and other items that are developed
and submitted to EPA for approval pursuant to this Consent Decree shall be complete and technically adequate. After review of any work plan, report, or other item that is required to be submitted, or revised and resubmitted, to EPA for approval
pursuant to this Consent Decree, EPA, after consultation with FDEP, shall in writing: (a) approve the submission; (b) approve the submission upon specified conditions; (c) approve part of the submission and disapprove the remainder;
or (d) disapprove the submission. In the event of disapproval of any portion of the submission, EPA shall include a statement of the reasons for such disapproval in its response. Plaintiffs’ receipt or acceptance of information or notice,
or approval of a submittal, does not bind Plaintiffs to the factual assertions and conclusions of the information, notice, or submittal. 

28.      If the submission is approved pursuant to Paragraph 27(a), Mosaic shall take all actions required by
the work plan, report, or other document, in accordance with the schedules and requirements of the work plan, report, or other document, as approved. If the submission is 

  
 – 36 – 

Table of Contents

 
conditionally approved or approved only in part, pursuant to Paragraph 27(b) or (c), Mosaic shall, upon written direction from EPA, take all actions required by the approved work plan, report, or
other item that EPA determines are technically severable from any disapproved portions, subject to Mosaic’s right to dispute only the specified conditions, the disapproval, or the determination of the technical severability of portions of the
submission under Section XI of this Consent Decree (Dispute Resolution). 
 29.      If the submission is
disapproved in whole or in part, pursuant to Paragraph 27(c) or 27(d), Mosaic shall, within sixty (60) Days or such other time as the Parties agree to in writing, correct all deficiencies and resubmit the plan, report, or other item, or
disapproved portion thereof, for approval, in accordance with the preceding Paragraphs. If the submission has been previously disapproved, EPA may impose an earlier due-date for re-submission, but not less than fourteen (14) Days.
If the re-submission is approved in whole or in part, Mosaic shall proceed in accordance with the preceding Paragraph. 

30.      Any stipulated penalties applicable to the original submission, as provided in Section IX (Stipulated
Penalties) of this Consent Decree, shall accrue during the sixty (60)-Day period or other agreed period, but shall not be payable unless the re-submission is untimely or is disapproved in whole or in part;
provided that, if the original submission was so deficient as to constitute a material breach of Mosaic’s obligations under this Consent Decree, the stipulated penalties applicable to the original submission shall be due and payable
notwithstanding any subsequent re-submission. 
 31.      If a resubmitted work plan, report, or other item,
or portion thereof, is disapproved in whole or in part, EPA, after consultation with FDEP, may again require Mosaic to correct any deficiencies in accordance with the preceding Paragraphs, may itself correct any

  
 – 37 – 

Table of Contents

 
deficiencies, or may finally disapprove the submission, subject to Mosaic’s right to invoke dispute resolution under Section XI (Dispute Resolution) and the right of EPA and FDEP to seek
stipulated penalties as provided in the preceding Paragraphs. If the re-submission is approved or corrected in whole or in part, Mosaic shall proceed in accordance with Paragraph 27. 

32.      Correction of Non-Compliance. 

(a)  If Mosaic determines, with or without notice from EPA and/or FDEP, that it is violating, or will violate, any requirement of
Section V (Compliance Requirements) of this Consent Decree, other than those set forth in Paragraphs 15(f) (temporary storage of First Saleable Product) and 25 (Financial Assurance), Mosaic shall submit with its report of the violation,
pursuant to Section VIII (Reporting Requirements) of this Consent Decree, and shall subsequently implement, a Correction Plan to rectify the violation, if it has not already corrected the violation by the time of the report. The Correction Plan
shall include a schedule for correcting the violation. 
 (b)  In the event of a violation subject to Paragraph 32(a), Mosaic
nevertheless shall be considered to be in compliance with this Consent Decree for purposes of: (1) continuing to manage those wastes that Paragraphs 15 through 18 allow to be input to Upstream Operations or Downstream Operations or managed in
Recovery Units or together with Bevill-Exempt Wastes or transferred among Mosaic’s Florida Facilities; and (2) assessing Mosaic’s compliance with this Consent Decree under Paragraphs 34, 79, 80
and 81 of this Consent Decree, provided that: 
 (1) Mosaic deposits wastes governed by Paragraphs 15-18 only in a Phosphogypsum Stack
System subject to the Stack System Requirements set forth in Paragraph 15(a); and 

  
 – 38 – 

Table of Contents

 (2)      Mosaic: 

(i)       Timely implements and completes its Correction Plan; or 

(ii)      Refers an allegation of non-compliance with Section V (Work Requirements) or with a Correction Plan
to dispute resolution pursuant to Section XI (Dispute Resolution) and either 

a.          Prevails in the dispute resolution or 

b.          Satisfactorily complies with an EPA or judicial directive to correct any
instances of non-compliance 
 (collectively, Continuing Compliance Criteria). Nothing in this Paragraph shall be construed as EPA approval of Mosaic’s
correction efforts pursuant to this Paragraph, as a waiver of stipulated penalties for the violation pursuant to Section IX (Stipulated Penalties), or as limiting the rights reserved by Plaintiffs under Section VI (Work Takeover) or Paragraph 82 of
this Consent Decree. EPA reserves the right to require, upon written request, that a Correction Plan be submitted to EPA for approval in accordance with Paragraphs 27-30, above. Mosaic’s compliance with
this Paragraph is without prejudice to its rights under Section X (Force Majeure) and Section XI (Dispute Resolution) of this Consent Decree. 

33.      Permits.   Where any compliance obligation under this Section requires Mosaic to
obtain a federal, state, or local permit or other form of approval, Mosaic shall submit timely and complete applications and take such actions as are necessary to obtain all such permits or approvals. A request for supplementation by the
permitting agency does not constitute a notice or finding that an application was incomplete for the purpose of this Paragraph unless the permitting agency determines that the original application was so deficient as to constitute a material breach
of Mosaic’s obligations under this Consent Decree. Mosaic may seek relief 

  
 – 39 – 

Table of Contents

 
under the provisions of Section X of this Consent Decree (Force Majeure) for any delay in the performance of any such obligation resulting from a failure to obtain, or a delay in obtaining, any
permit or approval required to fulfill such obligation, if Mosaic has submitted timely and complete applications and has taken such actions as are necessary to timely obtain all such permits or approvals. 

34.     Provided that Mosaic remains in compliance with Section V (Compliance Requirements) or the Continuing
Compliance Criteria set forth in Paragraph 32 at a Facility, that Facility shall not be required to operate as a Treatment Storage and Disposal Facility pursuant to Section 3005 of RCRA and its implementing federal and/or state regulations,
with respect to: 
   (a) the treatment, storage, transport, management, and disposal of Bevill-Exempt Wastes that have been commingled with hazardous wastes or otherwise managed in violation of law as alleged in the Complaint: 

(i) prior to the lodging of this Consent Decree, 

(ii) prior to completing the compliance projects set forth in Appendix 6 (RCRA Project Narrative and Compliance Schedule) as
provided by Paragraph 13, or 
 (iii) during timely implementation of a Correction Plan as set forth in Paragraph 32; 

(b) wastes that Paragraphs 15 through 18(a) allow to be input to Upstream Operations or Downstream Operations or managed in Recovery
Units or together with Bevill-Exempt Wastes; and 
 (c) wastes that Paragraph 18(b) allows to be
transferred among Mosaic’s Florida Facilities.

 VI. WORK TAKEOVER 

35.      In the event EPA determines that Mosaic has: (a) ceased implementation of any portion of the Work;
or (b) is seriously or repeatedly deficient or late in its performance of the Work; or (c) is implementing the Work in a manner that may cause an endangerment to human health or the environment, EPA, after consultation with FDEP and with
the joint approval of the EPA Region 4 Regional Administrator and the Assistant Administrator for the EPA Office of Enforcement and Compliance Assurance, may issue a written notice (Work Takeover Notice) to Mosaic. Any Work Takeover Notice issued by
EPA shall specify the grounds upon which such notice was issued and shall provide Mosaic a period of thirty (30) Days within which to remedy the circumstances giving rise to EPA’s issuance of such notice. 

36.      If, after expiration of the thirty (30) Day period specified in Paragraph 35 of this Section, the
Work Takeover Notice has not been withdrawn by EPA and Mosaic has not remedied to EPA’s satisfaction the circumstances giving rise to EPA’s issuance of the Work Takeover Notice, EPA at any time thereafter may undertake Work Takeover by:
(a) assuming and/or directing the performance of; (b) seeking the appointment of a receiver to direct the performance of; or (c) only with the concurrence of FDEP, accessing Financial Assurance to finance the performance of all or any
portions of the Work that EPA deems necessary to correct the violations or conditions that triggered the Work Takeover Notice pursuant to Paragraph 35 (Work Takeover). EPA shall notify Mosaic in writing (which writing may be electronic) if EPA
determines that implementation of a Work Takeover is warranted under this Section of the Consent Decree. In the event that EPA seeks to appoint a receiver to direct the performance of the Work, Mosaic shall not oppose such appointment on
grounds other than lack of competence or conflict of interest, but shall retain its right to challenge the underlying Work Takeover in 

  
 – 41 – 

Table of Contents

 
Dispute Resolution, as set forth in the following Paragraph and Section XI (Dispute Resolution) of this Consent Decree. In implementing any Work Takeover, EPA shall make reasonable efforts not to
interfere with Facility operations not directly affected by the conditions that triggered the Work Takeover. 

37.      In the event that Mosaic invokes Section XI (Dispute Resolution) of the Consent Decree with respect to
EPA’s Work Takeover and/or its selection of options set forth in Paragraph 36 (which must be disputed together with the underlying Work Takeover and pursuant to Paragraph 70(a) of this Consent Decree), EPA during the pendency of any such
dispute may, in its unreviewable discretion, commence and continue a Work Takeover until the earlier of: (a) the date that Mosaic remedies, to EPA’s satisfaction, the circumstances giving rise to issuance of the Work Takeover Notice; or
(b) the date that a final decision is rendered in accordance with Section XI (Dispute Resolution) of the Consent Decree requiring EPA to terminate such Work Takeover. 

38.      After commencement and for the duration of any Work Takeover, EPA or any appointed receiver shall have
immediate access to and benefit of any Financial Assurance provided pursuant to Paragraph 25 and Appendix 2 (Financial Assurance) of this Consent Decree to implement the Work. If EPA or any appointed receiver are unable to access to the
Financial Assurance, or the Work addressed by the Work Takeover is not covered by Financial Assurance, then any unreimbursed costs incurred by EPA in connection with the Work Takeover shall be considered a financial obligation owed by Mosaic to the
United States and collectible in an action to enforce this Consent Decree. Nothing in this Paragraph shall be construed to relieve Mosaic of its obligation to provide adequate Financial Assurance pursuant to Appendix 2. In the event that it is
determined in Dispute Resolution that the Work Takeover was not warranted, any 

  
 – 42 – 

Table of Contents

 
unexpended funds in a Stand-by Trust that originated from a letter of credit, surety bond or corporate guarantee shall be used to restore any pre-existing Trust Fund to the pre-Work Takeover level, if necessary, and any balance of unexpended funds shall be released and used to
re-establish the original financial mechanism(s). 

VII.      SUPPLEMENTAL ENVIRONMENTAL PROJECT 

39.      FDEP and Mosaic have agreed on a Supplemental Environmental Project (“SEP”) as described
herein in Appendix 9. Mosaic, under the oversight of FDEP, shall remediate seepage breakout at the Mulberry Facility South Cooling Pond as further described in Appendix 9, and subject to the following conditions: 

(a)        The cost of the SEP shall be based on direct expenditures for engineering services,
materials, and for other third-party contractors or vendors, where needed to perform the SEP (the “Applicable SEP Costs”). Mosaic shall complete the SEP work described herein in Appendix 9, to the extent the Applicable SEP Costs do
not exceed $1.2 Million. 
 (b)        Remediation shall continue to be performed by Mosaic until
performance in full has been completed as described in Appendix 9.
 (c)        If Mosaic
determines that the costs of the SEP will or are likely to exceed $1.2 million in Applicable SEP Costs as a result of an “Unanticipated Event” or “Differing Site Condition,” Mosaic shall immediately so inform FDEP and suspend
work and, to the extent feasible, do so prior to incurring Applicable SEP Costs in excess of $1.2 million. For the purposes of this paragraph, “Unanticipated Event” or “Differing Site Condition,” shall mean concealed or latent
physical conditions or subsurface conditions at a portion of the site corresponding to the SEP work that (i) materially differ from the conditions described in Appendix 9 or (ii) are of an unusual nature, differing materially from the
conditions ordinarily 

  
 – 43 – 

Table of Contents

 
encountered and generally recognized as inherent in the applicable SEP work. Following notice that performance of the SEP will exceed the above threshold, FDEP may either: (i) require a
modification to the SEP to allow the Applicable SEP Costs to not exceed $1.2 million, or (ii) reach an agreement with Mosaic on any additional funds and the source of such funds that may be used to fund all or some portion of the Applicable SEP
Costs in excess of $1.2 million.
 (d)    If Mosaic fails to timely submit the notification of completion, or otherwise
fails to complete the SEP within the timeframes provided in Paragraph 39(b), or if upon review of the certification of construction completion, FDEP determines that the project cannot be accepted due to a substantially incomplete certification of
completion or due to substantial deviations from the approved SEP, Mosaic will be notified, in writing, of the reason(s) that prevent the acceptance of the project. Mosaic shall address all of the matters identified by FDEP that are
inconsistent with the SEP described in Appendix 9, or the timeframes herein required, and submit a new certification of completion within 45 Days of receipt of FDEP’s notice, unless such FDEP notice specifies a greater period of time for
submittal of a new certification of completion. If Mosaic, despite its best efforts to do so, fails to complete the SEP or if upon review of the new submittal, FDEP determines that the SEP is still incomplete or not in accordance with the SEP
described in Appendix 9, Mosaic shall pay a stipulated penalty to FDEP equal to the greater of: (i) $1.2 Million (less the costs that Mosaic incurred on the SEP up to a maximum of $1.2 Million), or (ii) $25,000.

 VIII. REPORTING REQUIREMENTS 

40.      If Mosaic determines that it has violated or will violate, any requirement of this Consent Decree,
Mosaic shall (unless otherwise directed by EPA or FDEP) notify EPA and FDEP of such violation and its likely duration, in writing, within twelve (12) Days of the date Mosaic first becomes aware of the violation, with an explanation of the
likely cause of the violation and of the remedial steps taken, or to be taken, to prevent or minimize such violation. If the cause of a violation cannot be fully explained at the time the report is due, Mosaic shall so state in the
report. Mosaic shall investigate the cause of the violation and shall then submit an amendment to the report, including a full explanation of any identifiable cause(s) of the violation, within thirty (30) Days of the date Mosaic becomes
aware of the violation. Nothing in this Paragraph or Paragraphs 41 and 42 relieves Mosaic of its obligation to provide the notice required by Section X of this Consent Decree (Force Majeure). 

41.      Periodic Reporting

Decree, including, at a minimum, a narrative description of activities undertaken and the status of any construction or compliance measures; (i) a description of any violation of the requirements of this Consent Decree reported under Paragraph
40 and an explanation of the likely cause of such violation and of the remedial steps taken, or to be taken, to prevent or minimize such violation; (j) the log of any temporary use of units in Upstream Operations, Mixed-Use Units or
Grandfathered Units for the storage of the First Saleable Product, (k) the log of spills and leaks tracked pursuant to the BMP set forth in Appendix 5, and (l) identification of any confirmed “critical condition,” as defined and
reported to FDEP and/or EPA pursuant to Appendix 1. 
 (b)        Thereafter, and for a period of
two (2) years, Mosaic shall submit such reports to Plaintiffs for each Operating Facility on a semi-annual basis. Thereafter Mosaic shall submit such reports annually until such time as Mosaic submits the Closure Application for an Operating
Facility pursuant to Appendix 1 Attachment D (Closure of Phosphogypsum Stacks/ Stack Systems). Mosaic shall submit its next report within one-hundred-eighty (180) Days after the submission of the Closure Application, and annually
thereafter until this Consent Decree is terminated with respect to that Operating Facility. 

(c)      Following completion of the compliance projects “Big Holding Tank and Wash Solution System in
Phosphoric Acid Plant” and “Granulation Wash Reconfiguration,” in Appendix 6 (RCRA Project Narrative & Compliance Schedule), Mosaic shall submit to EPA and

Table of Contents

 
FDEP a report for each Operating Facility within forty-five (45) Days after the end of each calendar quarter identifying any transfer(s) of GHT Effluent to the BHT during the reporting
period, including the following information: (a) the date of any transfer(s); (b) the reason for the transfer; (c) the volume of the contents in the GHT when Mosaic started and ceased use of the transfer line; (d) the volume
transferred; and (e) a proposal for minimizing, if possible, any reoccurrence of the non-routine event that led to the transfer. These reports shall be submitted quarterly for a period of three (3) years following project completion.
Thereafter, Mosaic shall submit such reports annually until such time as Mosaic submits the Closure Application for a Facility pursuant to Appendix 1 Attachment D (Closure of Phosphogypsum Stacks/Stack Systems). 

(d)        Within forty-five (45) Days after the end of each calendar year after lodging of this
Consent Decree, Mosaic shall submit reports for each Closing Facility that shall include: (a) status of plans for closure and long-term care; and (b) identification of any confirmed “critical condition,” as defined and reported
to FDEP and/or EPA pursuant to Appendix 1. 
 42.      Whenever any violation of this Consent Decree, or any
other event affecting Mosaic’s performance under this Consent Decree or the performance of its Facility may pose an immediate threat to the public health or welfare or the environment, Mosaic shall, unless otherwise directed, notify EPA and
FDEP in Section XV (Notices), orally or by electronic or facsimile transmission as soon as possible, but no later than twenty-four (24) hours after Mosaic first knew of the event, and shall comply with the requirements of Appendix 1, Attachment
E (Critical Conditions and Temporary Measures). Any violation of this notice requirement shall be deemed to terminate on the Day that both Plaintiffs have received actual notice of the violation

or event from Mosaic or by other means. This notice requirement does not relieve Mosaic of its obligation to comply with any federal and state laws applicable to the violation or event. This
notice requirement is in addition to the requirement to provide notice of a violation of this Consent Decree set forth in the preceding Paragraph. 

43.      All reports shall be submitted to the persons designated to receive Notices for Plaintiffs in
Section XV (Notices) of this Consent Decree. All notices and submittals to “EPA and/or FDEP” under this Consent Decree (including Appendices), other than those required by this Section or that are submitted for approval pursuant to
Paragraphs 27-29, may be submitted to FDEP only, provided that a copy of the cover letter identifying the notice or submittal is also sent to EPA. Mosaic also shall supply EPA with a copy of such notice(s) or submittal(s) upon request by EPA. 

44.      Each report submitted by Mosaic under this Section shall be signed by a responsible corporate official
of Mosaic (as defined in 40 C.F.R. § 270.11(a)) and shall include the following certification: 
 I certify under penalty of law that
this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person
or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant
penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations. 
 This certification requirement
does not apply to emergency notifications where compliance would be impractical. 
 45.      The reporting
requirements of this Consent Decree do not relieve Mosaic of any reporting obligations required by the RCRA Requirements or by any other federal, state, or local 

  
 – 48 – 

Table of Contents

 
law, regulation, permit, or other requirement. However, the reporting requirements of this Consent Decree shall not require Mosaic to re-submit any report, plan or information submitted by Mosaic
to EPA and/or FDEP prior to the Effective Date of this Consent Decree. 
 46.      Any information provided
pursuant to this Consent Decree may be used by the Plaintiffs in any proceeding to enforce the provisions of this Consent Decree and as otherwise permitted by law. 

IX. STIPULATED PENALTIES 

47.      Mosaic shall be liable for stipulated penalties to the United States and FDEP for violations of this
Consent Decree as specified below, unless excused under Section X (Force Majeure). A violation includes failing to perform any obligation required by the terms of this Consent Decree, including any work plan or schedule approved under this
Consent Decree, according to all applicable requirements of this Consent Decree and within the specified time schedules established by or approved under this Consent Decree. 

48.      Civil Penalty.  If Mosaic fails to pay the civil penalty required to be paid under

58.      Subject to the provisions of Section XIII (Effect of Settlement/ Reservation of Rights) of this Consent
Decree, the stipulated penalties provided for in this Consent Decree shall be in addition to any other rights, remedies, or sanctions available to the United States or FDEP for Mosaic’s violation of this Consent Decree or applicable
law. Where a violation of this Consent Decree is also a violation of relevant statutory or regulatory requirements, Mosaic shall be allowed a credit for any stipulated penalties paid against any statutory penalties imposed for such violation.

 X. FORCE MAJEURE 

59.       Force majeure, for purposes of this Consent Decree, is defined as any event arising from causes
beyond the control of Mosaic, of any entity controlled by Mosaic, or of Mosaic’s contractors, that delays or prevents the performance of any obligation under this Consent Decree despite Mosaic’s best efforts to fulfill the obligation. The
requirement that Mosaic exercise best efforts to fulfill the obligation includes using best efforts to anticipate any potential force majeure and best efforts to address the effects of any potential force majeure

(1) as it is occurring and (2) following the potential force majeure such that the delay and any adverse effects of the delay are minimized to the greatest extent possible. Force
majeure does not include Mosaic’s financial inability to perform any obligation under this Consent Decree. 

60.      If any event occurs or has occurred that may delay the performance of any obligation under this Consent
Decree, whether or not caused by a force majeure event, Mosaic shall provide notice orally or by electronic or facsimile transmission as soon as possible, as provided in Section XV (Notices) of this Consent Decree, but not later than seven
(7) Days after the time when Mosaic first knew that the event might cause a delay. Within ten (10) Days thereafter, Mosaic shall provide written notice to EPA and FDEP with an explanation and description of the reasons for the delay;
the anticipated duration of the delay; all actions taken or to be taken to prevent or minimize the delay; a schedule for implementation of any measures to be taken to prevent or mitigate the delay or the effect of the delay; Mosaic’s rationale
for attributing such delay to a force majeure event if it intends to assert such a claim; and a statement as to whether, in the opinion of Mosaic, such event may cause or contribute to an endangerment to public health, welfare or the environment.
Mosaic shall include with any notice all available documentation supporting a claim that the delay was attributable to a force majeure event. Mosaic shall be deemed to know of any circumstance of which Mosaic, any entity controlled by Mosaic,
or Mosaic’s contractors knew or reasonably should have known. Failure to comply with the above requirements regarding an event shall preclude Mosaic from asserting any claim of force majeure regarding that event, provided, however, that if EPA,
despite the late notice, is able to assess to its satisfaction whether the event is a force majeure under Paragraph 59 and whether Mosaic has exercised its best efforts under Paragraph 60, EPA may, in its

  
 – 53 – 

Table of Contents

 
unreviewable discretion, excuse in writing Mosaic’s failure to submit timely notices under this Paragraph. 

61.      If EPA, after consultation with FDEP, agrees that the delay or anticipated delay is attributable to a
force majeure event, the time for performance of the obligations under this Consent Decree that are affected by the force majeure event will be extended by EPA, after consultation with FDEP, for such time as is necessary to complete those
obligations. An extension of the time for performance of the obligations affected by the force majeure event shall not, of itself, extend the time for performance of any other obligation. If EPA, after consultation with FDEP, agrees that the
delay is attributable to a force majeure event, EPA will notify Mosaic in writing of the length of the extension, if any, for performance of the obligations affected by the force majeure event. 

62.      If EPA, after consultation with FDEP, does not agree that the delay or anticipated delay has been or
will be caused by a force majeure event, EPA will notify Mosaic in writing of its decision. 
 63.      If
Mosaic elects to invoke the dispute resolution procedures set forth in Section XI (Dispute Resolution), it shall do so no later than fifteen (15) Days after receipt of EPA’s notice. In any such proceeding, Mosaic shall have the burden of
demonstrating by a preponderance of the evidence that the delay or anticipated delay has been or will be caused by a force majeure event, that the duration of the delay or the extension sought was or will be warranted under the circumstances, that
best efforts were exercised to avoid and mitigate the effects of the delay, and that Mosaic complied with the requirements of Paragraphs 59 and 60, above. If Mosaic carries this burden, the delay at issue shall not be a violation by Mosaic of the
affected obligation of this Consent Decree identified to EPA and the Court.

 XI. DISPUTE RESOLUTION 

64.      Unless otherwise expressly provided for in this Consent Decree, the dispute resolution procedures of
this Section shall be the exclusive mechanism to resolve all disputes arising under or with respect to this Consent Decree. Mosaic’s failure to seek resolution of a disputed issue under this Section shall preclude Mosaic from raising any
such issue as a defense to an action by the United States or FDEP to enforce any obligation of Mosaic arising under this Consent Decree. 

65.      Informal Dispute Resolution.  Any dispute subject to Dispute Resolution under this
Consent Decree shall first be the subject of informal negotiations, which may include any third-party assisted, non-binding alternative dispute resolution process
agreeable to the Parties. Mosaic shall submit a written Notice of Dispute to both the United States and FDEP within thirty (30) Days after receiving written notice from EPA (or FDEP with respect to Section VII (Supplemental Environmental
Projects)) of a decision that Mosaic disputes. The dispute shall be considered to have arisen on the later of the dates that the United States or FDEP receives a written Notice of Dispute. Such Notice of Dispute shall state clearly the
matter in dispute. The period of informal negotiations shall not exceed twenty (20) Days from the date that the dispute arises, unless that period is modified by written agreement between the United States (or FDEP with respect to Section
VII (Supplemental Environmental Projects)) and Mosaic. If the Parties cannot resolve a dispute by informal negotiations, then the position of EPA, after consultation with FDEP, or of FDEP with respect to Section VII (Supplemental Environmental
Projects, shall be considered binding, unless Mosaic invokes formal dispute resolution procedures as provided in the following Paragraph. 

  
 – 55 – 

Table of Contents

 66.      Formal Dispute Resolution.  If Mosaic
elects to invoke formal dispute resolution, Mosaic shall, within thirty (30) Days after the conclusion of the informal negotiation period, submit to EPA and FDEP, or of FDEP with respect to Section VII (Supplemental Environmental Projects, a
written Statement of Position regarding the matter in dispute. The Statement of Position shall include, but need not be limited to, any factual data, analysis, or opinion supporting Mosaic’s position and any supporting documentation relied
upon by Mosaic. 
 67.      EPA, after consultation with FDEP, or FDEP with respect to Section VII
(Supplemental Environmental Projects), shall submit its Statement of Position within forty-five (45) Days of receipt of Mosaic’s Statement of Position. The EPA or FDEP Statement of Position
shall include or clearly reference, but need not be limited to, any factual data, analysis, or opinion supporting that position and any supporting documentation relied upon by EPA or FDEP. Where appropriate, EPA (or FDEP with respect to Section
VII (Supplemental Environmental Projects)) may allow submission of supplemental statements of position by the Parties to the dispute. The EPA or FDEP Statement of Position shall be binding on Mosaic unless Mosaic files a motion for judicial
review of the dispute in accordance with the following Paragraph. 
 68.      Mosaic may seek judicial review
of the dispute by filing with the Court and serving on the United States and FDEP, in accordance with Section XV (Notices) of this Consent Decree, a motion requesting judicial resolution of the dispute. The motion must be filed within thirty
(30) Days of receipt of EPA’s Statement of Position pursuant to the preceding Paragraph. The motion shall contain a written statement of Mosaic’s position on the matter in dispute, including any supporting factual data, analysis,
opinion, or documentation, and shall set 

  
 – 56 – 

Table of Contents

 
forth the relief requested and any schedule within which the dispute must be resolved for orderly implementation of the Consent Decree. 

69.      The United States, after consultation with FDEP, or FDEP with respect to Section VII (Supplemental
Environmental Projects), shall respond to Mosaic’s motion within the time period allowed by the Local Rules of this Court. Mosaic may file a reply memorandum to the extent permitted by the Local Rules. 

70.      Standard of Review 

a.  Disputes Concerning Matters Accorded Record Review.  In any dispute brought under this Section pertaining to
the adequacy or appropriateness of plans, procedures to implement plans, schedules or any other items requiring approval by EPA under this Consent Decree; the adequacy of the Work performed pursuant to this Consent Decree; and all other disputes
that are accorded review on the administrative record under applicable principles of administrative law, EPA shall compile an administrative record of the dispute containing all Statements of Position, including supporting documentation and
referenced data or information, and Mosaic shall have the burden of demonstrating, based on the administrative record, that the position of the United States is arbitrary and capricious or otherwise not in accordance with law. 

b.  In any other dispute brought under this Section, Mosaic shall bear the burden of demonstrating that its position complies with
and furthers the objectives of this Consent Decree. 
 71.      The invocation of dispute resolution
procedures under this Section shall not, by itself, extend, postpone, or affect in any way any obligation of Mosaic under this Consent Decree, unless and until final resolution of the dispute so provides or unless ordered by the
Court. Stipulated penalties with respect to the disputed matter shall continue to accrue from the 

  
 – 57 – 

Table of Contents

 
first Day of noncompliance, but payment shall be stayed pending resolution of the dispute as provided in Paragraph 54. If Mosaic does not prevail on the disputed issue, stipulated penalties
shall be assessed and paid as provided in Section IX (Stipulated Penalties). 
 XII. INFORMATION COLLECTION AND RETENTION 

72.      The United States, FDEP, and their representatives, including attorneys, contractors, and consultants,
shall have the right of entry into any of Mosaic’s Florida Facilities, at all reasonable times, upon presentation of appropriate identification, to: 

a.    monitor the progress of activities required under this Consent Decree; 

b.    verify any data or information submitted to the United States or FDEP in accordance with the terms of this Consent
Decree; 
 c.  obtain samples and, upon request, splits of any samples taken by Mosaic or its representatives, contractors, or
consultants; 
 d.    obtain documentary evidence, including photographs and similar data; 

e.    assess Mosaic’s compliance with this Consent Decree; and 

f.    conduct, direct or review Work pursuant to Section VI (Work Takeover) of this Consent Decree. 

73.      Upon request, Mosaic shall provide EPA, FDEP and their authorized representatives splits of any samples
taken by Mosaic. Upon request, EPA and FDEP and their authorized representatives shall provide Mosaic splits of any samples taken by EPA, FDEP, and their authorized representatives. 

74.      Mosaic shall retain, and shall require its contractors and agents to preserve, all non-identical copies of all documents, records, or other information (including documents, records, emails or other information in electronic form and including any documents, records,

  
 – 58 – 

Table of Contents

 
data or other information underlying the submission of any Report required pursuant to Section VIII (Reporting Requirements)) in its or its contractors or agents possession or control, or that
come into its or its contractors’ or agents’ possession or control and that relate to Mosaic’s performance of its obligations under this Consent Decree or adherence to the requirements associated with the management of waste materials
allowed under Paragraphs 15 through 18 for a period of five (5) years after the creation of such documents, records or other information. This information-retention requirement shall apply regardless
of any contrary corporate or institutional policies or procedures. At any time during this information-retention period, upon request by the United States or FDEP, Mosaic shall provide copies of any
documents, records, or other information required to be maintained under this Paragraph.
 75.      At the
conclusion of the information-retention period provided in the preceding Paragraph, Mosaic shall notify the United States and FDEP at least ninety (90) Days prior to the destruction of any documents,
records, or other information subject to the requirements of the preceding Paragraph and, upon request by the United States or FDEP, Mosaic shall deliver any such documents, records, or other information to EPA or FDEP. Mosaic shall not dispose
of materials following the expiration of its five (5) year retention period more often than once a year. 

76.      In connection with any request for documents, records, or other information pursuant to this Consent
Decree, Mosaic may assert that certain documents, records, or other information are privileged under the attorney-client privilege or any other privilege recognized by federal law, provided that Mosaic shall
not assert a legal privilege for any data, records or information (excluding legal advice) generated or received in connection with Mosaic’s obligations pursuant to the requirements of this Consent Decree. If Mosaic asserts a privilege, it

  
 – 59 – 

Table of Contents

 
shall provide the following: (1) the title of the document, record, or information; (2) the date of the document, record, or information; (3) the name and title of each author of
the document, record, or information; (4) the name and title of each addressee and recipient; (5) a description of the subject of the document, record, or information; and (6) the privilege asserted by Mosaic. If Plaintiffs
and Mosaic disagree as to whether a particular document or record is privileged, Mosaic shall deliver such document or record to the United States or the FDEP unless it invokes dispute resolution pursuant to Section XI (Dispute Resolution), in which
case, Mosaic shall not have an obligation to deliver such document or record until a final determination is made, pursuant to the procedures set forth in Section XI (Dispute Resolution), that such document or record is not privileged. 

77.      Mosaic may also assert that information provided pursuant to this Consent Decree is protected as
Confidential Business Information (CBI) under the criteria and procedures set forth in 40 C.F.R. Part 2, provided that: (a) Mosaic shall not assert a CBI claim with respect to any physical, sampling, monitoring, or analytical data other than
data related to: (i) development of new or modified products; (ii) development of new or modified production processes; (iii) production materials or analyses collected for quality control or other manufacturing purposes; or
(iv) analyses undertaken for competitive business purposes; and (b) Mosaic shall not assert a CBI claim for Financial Assurance information required to be provided pursuant to Paragraphs 10.e, 15.(e) and 32 of Appendix 2 of this Consent
Decree. If Mosaic claims any information related to Financial Assurance submissions and Cost Estimates is CBI, Mosaic shall submit two versions, one version with the CBI material redacted, and so identified in the document, which will be publicly
available, and the second version will contain the CBI material. 

  
 – 60 – 

Table of Contents

 78.      This Consent Decree in no way limits or affects any right
of entry and inspection, or any right to obtain information, held by the United States or FDEP pursuant to applicable federal or state laws, regulations, or permits, nor does it limit or affect any duty or obligation of Mosaic to maintain documents,
records, or other information imposed by applicable federal or state laws, regulations, or permits. 
 XIII. EFFECT OF
SETTLEMENT/RESERVATION OF RIGHTS 
 79.      This Consent Decree resolves the civil claims of the United
States and FDEP against Mosaic, and, as to any liability arising out of Mosaic’s liability only, The Mosaic Company, for the violations at the Facilities alleged in the Complaint filed in this action through the date of the lodging of
the Consent Decree. This Consent Decree also resolves such claims, if any, of the United States and FDEP against the corporate officers, directors, and employees, acting in their capacities as such, of Mosaic or The Mosaic Company, but
only as to liability arising out of Mosaic’s liability. For continuing violations alleged in the Complaint, provided that Mosaic complies with this Consent Decree at a Facility, as set forth in Paragraph 81, from the date of lodging of the
Consent Decree through its Effective Date, these claims shall also be resolved through the Effective Date of this Consent Decree, as of the Effective Date, for that Facility; and, provided that Mosaic complies with the Consent Decree at a Facility
from the Effective Date of this Consent Decree through the date of termination of this Consent Decree for that Facility pursuant to Section XIX (Termination), these claims shall be finally resolved as of the date the Consent Decree terminates for
that Facility. 
 80.      Provided that Mosaic is in compliance with this Consent Decree, and subject to the
reservation set forth below, Plaintiffs covenant not to sue or take administrative action under 

  
 – 61 – 

Table of Contents

 
Section 3008(a) of RCRA, 42 U.S.C. § 6928(a), or its state counterpart, seeking to require Mosaic’s Facilities to comply with the RCRA Requirements, with respect to:
(a) the generation, treatment, storage, transport, management, and disposal of Bevill-Exempt Wastes that have been commingled with hazardous wastes or otherwise managed in violation of law as alleged in
the Complaint, and that are resolved in accordance with Paragraph 79; and (b) wastes that Paragraph 15-18 of this Consent Decree allow to be input to Upstream Operations or Downstream Operations or managed in Recovery Units or with Bevill-Exempt Wastes or transferred among Mosaic’s Florida Facilities. Nothing in this Paragraph, however, shall affect Plaintiffs’ rights to determine and require necessary Corrective Action Work in
accordance with Paragraphs 20 and 23 of this Consent Decree, or to restrict Non-CD Corrective Action that may be required at a Facility pursuant to Plaintiffs’ residual authorities under federal, state, and local laws. 

81.      The resolution under this Section XIII (Effect of Settlement/Reservation of Rights) of the
Plaintiffs’ civil claims set forth in the Complaint and the Plaintiffs’ covenants not to sue are expressly conditioned upon Mosaic’s timely and satisfactory compliance with the requirements of this Consent Decree. For the purposes of
this Paragraph (and Paragraphs 79 and 80), and with respect to those wastes that Paragraphs 15 through 18 allow to be input to Upstream Operations or Downstream Operations, managed in Recovery Units or together with
Bevill-Exempt Wastes, or transferred among Mosaic’s Florida Facilities, compliance with the Continuing Compliance Criteria set forth in Paragraph 32 constitutes compliance with this Consent Decree. 

82.      The United States and FDEP reserve all legal and equitable remedies available to enforce the provisions
of this Consent Decree, and Mosaic reserves all legal and equitable defenses available to it in the defense of any such enforcement. This Consent Decree shall not 

  
 – 62 – 

Table of Contents

 
be construed to limit the rights of the United States or FDEP to obtain penalties or injunctive relief under the federal and state environmental statutes or their implementing regulations, or
under other federal or state law, regulations, or permit conditions, including Section 3008(h) of RCRA, 42 U.S.C. § 6928(h), except as expressly specified in Paragraphs 79 and 80, and Mosaic in any such action shall not assert any defense
based upon the contention that such claims raised by the Plaintiffs were or should have been brought in the instant case under principles of waiver, res judicata, collateral estoppel, issue preclusion, claim preclusion, claim-splitting, or other such defense. The United States and FDEP further retain all authority and reserve all rights to take any and all actions authorized by law to protect human health and the environment,
including Corrective Action Work and Non-CD Corrective Action, and all legal and equitable remedies to address any imminent and substantial endangerment to the public health or welfare or the environment arising at, or posed by, Mosaic’s
Facilities, whether related to the violations addressed in this Consent Decree or otherwise. 
 83.      This
Consent Decree is not a permit, or a modification of any permit, under any federal, State, or local law or regulation. While this Consent Decree resolves the Parties’ dispute regarding the violations alleged in the Complaint as set forth
in Paragraph 79, compliance with the terms of this Consent Decree does not guarantee compliance with all applicable federal, state, or local laws or regulations. Except as provided in Paragraphs 34, 79 and 80 of this Consent Decree, Mosaic is not
relieved of its obligation to achieve and maintain compliance with all applicable federal, State, and local laws, regulations, and permits; Mosaic’s compliance with this Consent Decree shall be no defense to any action commenced by Plaintiffs
pursuant to any such law, regulation, or permit, except as expressly specified in Paragraphs 34, 79 and 80.

  
 – 63 – 

Table of Contents

 84.      This Consent Decree does not limit or affect the rights of
the Parties against any third-parties (persons not a Party to this Consent Decree), nor does it limit the rights of third-parties except as otherwise provided by the doctrine of federal preemption or by other applicable principles of law or
precedent. 
 85.      This Consent Decree shall not be construed to create rights or obligations in, or grant
any cause of action to, any third-party. 
 86.      Nothing in the Complaint filed in this action or in this
Consent Decree, including the execution and implementation of this Consent Decree, shall constitute an admission by Mosaic of any violation of the RCRA Requirements or of any of the allegations of the Complaint. Mosaic reserves all rights to dispute
the factual and legal representations of the Complaint and Consent Decree except in an action to enforce this Consent Decree by a Party. The terms of this Consent Decree may not be used as evidence in any litigation between the Parties except
(a) pursuant to Section XI (Dispute Resolution), (b) in an action to enforce this Consent Decree, or (c) in an action by Plaintiffs in which Mosaic asserts a defense based on this Consent Decree. 

XIV. COSTS 

87.      The Parties shall bear their own costs of this action, including attorneys’ fees, except that the
United States and FDEP shall be entitled to collect costs (including attorneys’ fees) incurred in any action necessary to access Financial Assurance pursuant to Paragraph 26 and Appendix 2 (Financial Assurance) of this Consent Decree, or
to collect any portion of the civil penalty or any stipulated penalties or other costs due under this Consent Decree but not paid by Mosaic.

XVI. EFFECTIVE DATE 

91.      The Entry Date of this Consent Decree shall be the date of a Final Order by which this Consent Decree
is entered by the Court or by which a motion to enter the Consent Decree is granted, whichever occurs first, as recorded on the Court’s docket. The Effective Date of this Consent Decree shall be the later of the Entry Date of this Consent
Decree or the Entry Date of the Consent Decree resolving claims by the United States and the Louisiana Department of Environmental Quality against Mosaic relating to Mosaic’s facilities in Louisiana. The filing or

  
 – 67 – 

Table of Contents

 
pendency of an appeal of the Court’s entry of this Consent Decree shall not stay the Effective Date, except as may be otherwise determined pursuant to Paragraph 93 (Modification). 

In the event that either Consent Decree is not entered by the Court, the Parties shall jointly stipulate to stay any previously entered
Consent Decree. Notwithstanding the foregoing, Mosaic hereby agrees that it shall be bound from the date of its execution of this Consent Decree to perform obligations scheduled in this Consent Decree to occur prior to the Effective Date. 

XVII. RETENTION OF JURISDICTION 

92.      The Court shall retain jurisdiction over this case until termination of this Consent Decree for all
Facilities, pursuant to Section XIX (Termination), for the purpose of resolving disputes arising under this Consent Decree (including disputes under any Trust Agreements entered pursuant hereto) or entering orders modifying this Consent Decree,
pursuant to Sections XI (Dispute Resolution) and XVIII (Modification), or effectuating or enforcing compliance with the terms of this Consent Decree. 

XVIII. MODIFICATION 

93.      The terms of this Consent Decree may be modified only by a subsequent written agreement of the Parties
to this Consent Decree as set forth herein. Any modifications to the provisions of Appendices 1 through 7 hereto, and any other modifications to any other provisions of this Consent Decree that do not constitute a material change to this
Consent Decree, may be made without approval by the Court upon written agreement between Mosaic and the United States, after consultation with FDEP. Any modifications to the provisions of Appendices 8 and 9 may be made without approval by the Court
upon written agreement between Mosaic and FDEP, after consultation with the United States. Any such changes shall become enforceable under this Consent Decree upon execution by Mosaic and the United States (for changes to the Consent

  
 – 68 – 

Table of Contents

 
Decree or Appendices 1 through 7) or Mosaic and FDEP (for changes to Appendices 8 and 9), shall be made available to the public by EPA and FDEP (except to the extent such changes contain
information determined to be CBI pursuant to Paragraph 77 and 40 C.F.R. Part 2,) and shall periodically be filed by EPA or FDEP with the Court. Any other modifications agreed to by the Parties shall be effective only upon approval by the
Court. Except as otherwise provided in this Paragraph and Paragraph 95, a Party’s refusal to agree to a modification of this Consent Decree shall be subject to dispute resolution, but a Party seeking judicial review of such a refusal
shall bear the burden of demonstrating that it is entitled to the requested modification based on a significant change in factual conditions or the law or other reason that would make inequitable the continued application of the Consent Decree
without the modification sought. 
 94.      In the event that a potential transferee under Section II of this
Consent Decree has agreed to become a party to this Consent Decree and subject to all its terms and provisions, it may do so upon written approval of the United States pursuant to Section II (Applicability) of this Consent Decree and Section XVIII
(Modification), without further order from the Court, in which event a supplemental signature page will be affixed to this Consent Decree and filed with the Court. 

XIX. TERMINATION 

95.      Periodic Review of Work Status.    At least once every three (3) years,
and more often if the Parties so agree, the Parties shall meet to review the status of the Work and to evaluate whether discrete portions of the Work have either been completed or may be accomplished and supervised under an EPA or FDEP
administrative order or permit in lieu of this Consent Decree. If all Parties agree to such a modification, such agreement shall be memorialized in a written modification to this Consent Decree pursuant to Section XVIII

  
 – 69 – 

Table of Contents

 
(Modification) and shall not require judicial approval. If the Parties agree that such modifications allow this Consent Decree to be terminated as to one or more Facilities, the Parties
shall submit, for the Court’s approval, a joint stipulation terminating the Consent Decree for the relevant Facilities. The Parties’ inability to reach agreement under this Paragraph shall not be subject to dispute resolution or judicial
review. 
 96.      Completion of Work.    Within ninety (90) Days after
Mosaic concludes that all Work required under this Consent Decree has been fully performed at a Facility, EPA and/or FDEP may conduct an inspection of the Facility to be attended by EPA, FDEP and Mosaic at a mutually agreeable time. Following
the inspection, and correction of any problems or deficiencies noted by EPA, after consultation with FDEP, Mosaic shall submit one or more written reports by a third-party registered professional engineer in the relevant technical field, certifying
compliance with Section V (Compliance Requirements) of this Consent Decree that the Work has been completed in full satisfaction of the requirements of this Consent Decree. The reports shall indicate the case name and civil action number, and shall
be submitted, together with a request for Acknowledgment of Completion, in accordance with Section VIII (Reporting Requirements) of this Consent Decree. Third-party engineer certification of any of the written
reports may be waived at EPA’s discretion, after consultation with FDEP. 
 97.      If, after review of
the written report(s) and certification and consultation with FDEP, EPA determines that any portion of the Work has not been completed in accordance with this Consent Decree, EPA will notify Mosaic in writing of the activity(ies) and/or
obligation(s) that must be undertaken to complete the Work. EPA will set forth in the notice a schedule for performance of the activity(ies) and/or obligation(s) required under the Consent Decree, or will require Mosaic to submit a schedule for
EPA approval pursuant to Section V (Compliance 

  
 – 70 – 

Table of Contents

 
Requirements) of this Consent Decree. Mosaic shall perform all activities described in the notice in accordance with the specifications and schedules established therein, subject to
Mosaic’s right to invoke the dispute resolution procedures set forth in Section XI (Dispute Resolution) of this Consent Decree. 

98.      If EPA concludes, based on the initial or any subsequent request for an Acknowledgment of Completion by
Mosaic, and after reasonable opportunity for review and comment by FDEP, that the Work has been fully performed in accordance with this Consent Decree, EPA will so notify Mosaic in writing, which notice shall constitute the Acknowledgment of
Completion. 
 99.      Termination.    After Mosaic has completed the requirements
set forth in Paragraphs 96 and 97 of this Section, has obtained an Acknowledgment of Completion, has complied with all other requirements of this Consent Decree, and has paid the civil penalty and any accrued stipulated penalties as required by this
Consent Decree, Mosaic may serve upon the United States and FDEP a Request for Termination, stating that Mosaic has satisfied those requirements, together with all necessary supporting documentation. A Request for Termination may address one or more
of Mosaic’s Facilities. 
 100.    Following receipt by the United States and FDEP of Mosaic’s Request for

 APPENDIX 1- OPERATING AND CLOSURE REQUIREMENTS FOR THE 

PHOSPHORIC ACID PRODUCTION INDUSTRY IN FLORIDA 

ATTACHMENT A: SITE ASSESSMENT, REPORTING, AND CORRECTIVE ACTION 

SAMPLING AND ANALYSIS WORKPLAN 

Defendant’s obligations pursuant to this Attachment A are governed by Paragraphs 20 and 23 of the Consent Decree. 

 

			
	1)	 	The Defendant shall submit to FDEP and/or EPA for approval an Outline for a Sampling and Analysis Workplan (“Outline”), for carrying out the required monitoring, testing, analysis, and reporting.
		
	2)	 	The Defendant shall submit to FDEP and/or EPA a Sampling and Analysis Workplan (“Workplan”), unless Defendant has already submitted a Sampling and Analysis Workplan that has been approved by FDEP and/or EPA and is
consistent with this Attachment.
		
	3)	 	The Sampling and Analysis Workplan shall be designed to determine the presence, magnitude, extent, direction, and rate of movement of any hazardous waste, hazardous constituents, and/or constituents of concern (“COC”)
within and beyond the Facility boundary. COCs shall be limited to those contaminants that are reasonably likely to be found at the Facility. The Workplan shall document the procedures the Defendant shall use to assess sampling and analysis data that
is generated and that relate to the purposes of this Attachment. The Workplan shall also document the procedures the Defendant shall use to conduct those activities necessary to: characterize the source(s) of contamination; characterize the
potential pathways of contaminant migration; define the degree and extent of contamination; and identify actual or potential human and/or ecological receptors. The Defendant may implement the work contained in the Workplan in a multi-phased
approach. A specific schedule for expeditious implementation of all activities shall be included in the Workplan. At a minimum, the Workplan for assessment shall include the following [All requirements below would be
Facility-specific]:

  

							
	      	 		 	(a)	    	A sediment and/or soil, as appropriate, sampling and analysis section to collect and analyze representative sediment and/or soil samples to determine the nature and extent of potential contamination, both vertically and
horizontally. Areas of sampling shall include process areas, areas of historical spills and/or historical contamination, areas of waste management, other Facility operation areas (to be defined), stormwater and non-Process Wastewater ditches and
ponds, and ditches associated with National Pollutant Discharge Elimination System (“NPDES”) outfall(s). The Workplan must define the number, location, and depth of the samples, and the parameters for analysis. The number of samples shall

Attachment A: Site Assessment, Reporting, and Corrective Action 

Table of Contents

							
	        	 	(10) days in advance of engaging in any field activities at the Facility conducted pursuant to this Attachment. At the request of FDEP and/or EPA, the Defendant shall provide, or allow FDEP and/or EPA or its authorized
representatives to take, split and/or duplicate any of the samples collected by the Defendant pursuant to this Attachment. Similarly, at the request of the Defendant, FDEP and/or EPA will allow the Defendant or its authorized representatives to take
split and/or duplicate any of the samples collected by FDEP and/or EPA under this Attachment, provided that such sampling shall not delay FDEP and/or EPA’s proposed sampling activities. Nothing in this Attachment shall limit or otherwise affect
FDEP’s and/or EPA’s authority to collect samples pursuant to applicable law, including, but not limited to, RCRA and/or CERCLA.

 RISK ASSESSMENT AND CORRECTIVE ACTION 

 

							
	17)	 	If Defendant confirms the existence of any hazardous waste, hazardous constituents, or COCs exceeding the higher of either (i) action levels established through either the implementation
of the Facility’s 3013 Order, or Appendix A-1, or (ii) background concentrations where appropriate, and (a) such exceedances are found within or beyond the Facility boundary in soil, sediment, or Surface Water and/or (b) such
exceedances may be emanating from the Facility in Groundwater at or beyond the “zone of discharge” (collectively, “Exceedance”), then the Defendant shall consult with FDEP and may either:
			
		 	a)	 	Pursuant to Chapter 62-780 F.A.C., cleanup such hazardous waste, hazardous constituents, or COCs to the cleanup target levels set forth in Chapter 62-777 F.A.C., or cleanup criteria provided
in Rule 62-780.680, F.A.C.; or
			
		 	b)	 	Conduct a risk assessment to demonstrate that Corrective Action Work is not warranted. Should Defendant choose to conduct a risk assessment, it shall submit for approval a Risk Assessment
Plan to FDEP and/or EPA, within forty-five (45) days of confirming the Exceedance. The Risk Assessment Plan shall address both environmental and human receptors potentially affected by the Exceedance and shall contain, but not be limited to the
following elements: description of the Facility; scope of the risk assessment; identification and description of the hazardous waste, hazardous constituents or COCs; description of sampling methods and collection strategies; exposure assessment
(including identification of exposure pathways); toxicity assessment; and risk characterization. If necessary, the Defendant shall contact FDEP and/or EPA and obtain any publicly available guidance or models that will assist in the development of
the Risk Assessment Plan and the subsequent Risk Assessment Report. A Risk Assessment satisfactorily performed pursuant to Rule 62-780.650 F.A.C. (Risk Assessment), and approved by FDEP or EPA satisfies the requirements of this Subparagraph 17b. If
Defendant submits a Risk Assessment Plan, then:
				
		 		 	i)	 	The Defendant shall begin implementation of the work under the Risk Assessment

  
 5 

Attachment A: Site Assessment, Reporting, and Corrective Action 

Table of Contents

							
		 		 		 	Plan within thirty (30) days of written approval by FDEP and/or EPA of the Risk Assessment Plan; and
				
		 		 	ii)	 	The Defendant shall submit a written Risk Assessment Report to FDEP and/or EPA within ninety (90) days after completion of the work under the Risk Assessment Plan. The Risk Assessment Report must include the following
information at a minimum: a description of the risk assessment; a summary of the results of the risk assessment; a summary of the problems encountered in doing the risk assessment; and an explanation of the activities that need to be taken to
address the risks identified by the assessment. If the conclusion is that there is no unacceptable risk to human health or the environment, within the meaning of pertinent standards or guidance, the report may request a No Further Action
determination for some or all of the areas of investigation, which FDEP shall process and may grant, pursuant to the Florida Phosphogypsum Rules and applicable state law. The Defendant shall contact FDEP and/or EPA and obtain any publicly available
guidance or models that will assist in the development of the Risk Assessment Report.
		
	18)	 	If FDEP and/or EPA determine by applying their then-existing rules, standards, criteria, or guidelines and after considering the available data, and including, where applicable, the final Sampling and Analysis Report
that Defendant submitted in accordance with Paragraph 5, and/or the Risk Assessment Report that Defendant submitted in accordance with Paragraph 17, that an Exceedance exists that presents a risk to human health or the environment, the Defendant
within ninety (90) days after notification by FDEP and/or EPA shall:
			
		 	a)	 	Submit for approval a Corrective Action Plan to FDEP and/or EPA. The Corrective Action Plan must include sections addressing: (1) the identification and evaluation of potential remedial alternatives for the
Exceedances that have been identified at the Facility; and (2) those actions appropriate to remediate, control, prevent or mitigate the Exceedance. The Corrective Action Plan shall, as appropriate, address the relevant factors listed in Rules
62-780.690(1-4) and 62-780.700(1-6), F.A.C. If necessary, the Defendant shall contact FDEP and/or EPA and obtain any publicly available guidance or models that will assist in the development of the Corrective Action Plan and associated reports.
Corrective Action Work under this Paragraph that is performed pursuant to Rules 62-780.690 (Natural Attenuation Monitoring) or 62-780.700, F.A.C. (Active Remediation), and approved by FDEP or EPA, shall be deemed to satisfy the requirements of this
Paragraph 18.
				
		 		 	i)	 	The Defendant shall begin implementation of the Corrective Action Work under the portion of the Corrective Action Plan addressing the identification and examination of the potential alternative remedies within sixty (60) days
after receiving written approval from FDEP and/or EPA. The Defendant shall, within ninety (90) days after completion of the identification and examination work, submit to FDEP and/or EPA a Corrective Action Evaluation Report which includes an
evaluation of each remedial

  
 6

		 		 		 	alternative, including all information gathered and studies conducted (e.g., bench scale or pilot tests). This Report must contain adequate information to enable FDEP and/or EPA to make a decision as to the
adequacy and appropriateness of the corrective action selection.
				
		 		 	ii)	 	Defendant will be notified by FDEP and/or EPA, upon review of the Corrective Action Evaluation Report, if no further action is required or which selected remedies need to be implemented at the Facility. If determined
that Corrective Action Work is needed, FDEP and/or EPA will review, evaluate, and approve the selected Corrective Action Work from the Corrective Action Evaluation Report, reject any alternative provided in the report or direct Defendant to develop
a different remedial alternative or corrective action performance standard.
					
		 		 		 	(1)	 	FDEP and/or EPA will draft a statement of basis and seek public comment. FDEP and/or EPA will consider public comments regarding the proposed
					
		 		 		 		 	corrective measures. FDEP and/or EPA will make publicly known the final decision regarding the selected corrective measures.
					
		 		 		 	(2)	 	If FDEP and/or EPA determine that Corrective Action Work is needed, the Defendant shall submit a Corrective Action Work Implementation Plan within one hundred and twenty (120) days after receiving notification to implement
Corrective Action Work as directed by FDEP and/or EPA. The Corrective Action Work Implementation Plan shall include, at a minimum, sections addressing: engineering design; construction, operation and maintenance; monitoring and performance
monitoring; waste management; health and safety plan; schedule; corrective measure goals; reporting requirements; and, if required, public participation.
				
		 		 	iii)	 	The Defendant shall submit to FDEP and/or EPA a Corrective Action Certification Report within forty-five (45) days after completion of the corrective measures. The Corrective Action Certification Report shall
contain the following minimum information: a description of the Corrective Action Work completed; summaries of results and documentation of attainment of performance requirements; summaries of all the problems encountered; summaries of
accomplishments and/or effectiveness of Corrective Action Work; and a certification of completion signed by the Defendant and by an independent, registered Professional Engineer skilled in the appropriate technical discipline(s). The Corrective
Action Certification Report will be reviewed by FDEP and/or EPA for adequacy and will be subject to public comment if required. Upon determination that Corrective Action Work has been completed, FDEP and/or EPA will issue a No Further Action
determination. Nothing in this section shall preclude the Defendant from requesting a No Further Action determination concerning discrete areas where Corrective Action Work concerning that area
has

Attachment A: Site Assessment, Reporting, and Corrective Action 

Table of Contents

 APPENDIX A-1 

Screening Criteria- Action Levels for Assessment of Corrective Action 

 

	I.	Definition 

 Action levels are conservative health-based concentrations of hazardous
wastes and/or hazardous constituents determined to be indicators for the protection of human health or the environment. Action levels shall be set by FDEP and/or EPA for all hazardous wastes and/or hazardous constituents identified through
Attachment A which FDEP and/or EPA has reason to believe may have been released in soils, sediments, or Surface Water, or in Groundwater (at or beyond the zone of discharge) from the Facility into the environment. Should the concentration of
hazardous wastes and/or hazardous constituents in soils, sediments, or Surface Water, or in Groundwater (at or beyond the zone of discharge) exceed the action levels established for any environmental medium, FDEP and/or EPA may require the
Respondent to conduct a Risk Assessment and/or perform Corrective Action. If FDEP and/or EPA determine that concentrations of hazardous wastes and/or hazardous constituents released from the Facility, below established action levels, may pose a
substantial threat to human health or the environment given site-specific exposure conditions, cumulative effects, ecological concerns or other factors, then FDEP and/or EPA may require a Risk Assessment pursuant to Paragraph 17b of Attachment A.

 Action levels shall be concentration levels that satisfy the following criteria. 

 

	II.	Soils 

 Action levels for constituents in soils shall be derived from the most stringent of levels
established by FDEP or EPA’s Regional Screening Levels. Pursuant to FDEP’s Corrective Action Program, industrial soil levels may be applied for onsite soil as long as the current site use remains industrial. 

 

	III.	 Sediment 

 Action levels are not available for constituents in
sediment. Screening levels (not action levels) for constituents in sediment shall be concentrations that will be established using: 

1.        Sediment Quality Assessment Guidelines (SQAGs). The marine and freshwater guidelines are
located at: http://www.dep.state.fl.us/water/monitoring/sediments.htm 

2.        For those parameters for which there is no SQAG, the latest Sediment and Soil Screening
Values for ecological risks as calculated by FDEP and/or EPA (Region 4 Cleanup Ecological and Health Risk Assessment Bulletins (RAGS Supplement)) will be applied as screening levels (not action levels) to identify site-specific constituents for

  
 9 

Appendix A-1: Screen Criteria – Action Levels for Assessment of Corrective Action 

Table of Contents

 
which action levels shall be established. 
  
  

	IV.	Groundwater 

 Action levels for constituents in Groundwater at or beyond the zone of
discharge shall be concentrations specified as: 
 1.        Maximum Contaminant Levels
(“MCLs”) established at 40 C.F.R. Part 141, or the applicable state law or Facility permit requirements for the State in which the Facility is located, these action levels must meet appropriate aquatic water quality criteria if it is
determined through the process outlined in Attachment A that Groundwater has the potential to impact Surface Water. 

2.        For facilities where the MCL is the most stringent standard for individual contaminants, if
the Natural Background exceeds the MCL, representative Natural Background will be the default Groundwater standard, unless the applicable state law or Facility permit is more stringent than Natural Background for that contaminant, in which case the
applicable state law or Facility permit will provide the appropriate standard for that contaminant. 
  

	V.	Surface Water 

 Action levels for constituents in Surface Water shall be concentrations
specified as: 
 1.        The more stringent of FDEP and/or EPA Surface Water Screening Values for
ecological risk; 
 2.        If action levels are not available from the screening values, Ambient
Water Quality Criteria as established by the Clean Water Act will be used.

 APPENDIX 1- OPERATING AND CLOSURE REQUIREMENTS FOR THE 

PHOSPHORIC ACID PRODUCTION INDUSTRY IN FLORIDA 

ATTACHMENT B: GROUNDWATER AND ZONE OF DISCHARGE REQUIREMENTS 

I. Zone of Discharge Requirements 
 A. Establishment
of the Zone of Discharge 
 Subject to the modification provisions set forth in Section I.B. (Modifications to an Established Zone of Discharge or
Monitoring Requirements) of this Attachment: 
 (1) No zone of discharge shall be allowed into potable Groundwater, unless authorized by FDEP (including by
permit) before the effective date of the Consent Decree or by this Attachment. Unless state law or a state-issued permit provides otherwise, zones of horizontal discharge shall extend no farther than to the Facility’s current property boundary
or the existing permitted boundary, where a permit applies, unless, after consultation with Mosaic, FDEP determines that a smaller zone of discharge will afford necessary protection to the designated use of adjacent surface Waters outside the zone
of discharge at a cost that is commensurate with the benefits to the public of such protection. Vertical zones of discharge shall be maintained where permitted prior to the date of entry of the Consent Decree. 

(2) Where multiple sites occur within close proximity, a single zone of discharge for the sites may be established at the discretion of FDEP and/or EPA. 

(3) Within the zone of discharge, if a Statistically Significant increase in contaminant concentration (including corrosivity) in Groundwater is discovered,
which EPA or FDEP determines constitutes an imminent and substantial endangerment to human health and/or the environment, then the hazard shall be addressed in accordance with Section I. D. (Zone of Discharge-Corrective Action) of this Attachment.

 B. Modifications to an Established Zone of Discharge or Monitoring Requirements 

(1) At any time, FDEP and/or EPA, after consultation with each other, may revise the zone of discharge and/or monitoring requirements for any of the reasons
described in (1)(a) through (e) of this Section. Also, Mosaic may petition for a modification in the zone of discharge and/or monitoring requirements for any of the reasons described in (1)(a) through (e) of this Section. 

(a) Monitoring data indicate that the discharge plume has resulted or may foreseeably result in a violation of applicable water quality standards beyond the
boundary of the existing zone of discharge; 
 (b) Continuation of the existing zone of discharge will impair the designated use of underground sources of
drinking water or the Surface Waters immediately affected by the Groundwater; 
 (c) Continuation of the existing zone of discharge may result in an
imminent and substantial 

  
 11 

Appendix B: Groundwater and Zone of Discharge Requirements 

Table of Contents

 
endangerment to human health or the environment; 
 (d) The monitoring data provided by Mosaic are
inadequate to allow a determination of compliance with applicable zone of discharge limitations and the owner fails to provide reasonable additional data requested by FDEP and/or EPA; or 

(e) A change in the chemical, physical, or microbiological composition, or the volume or the location of the discharge, requires a change in the zone of
discharge or the monitoring scheme to assure compliance. 
 (f) If FDEP determines that other information is necessary to ascertain if a modification to the
zone of discharge is warranted, Mosaic must submit such additional information upon request. 
 Mosaic also shall provide any such additional information
requested by EPA. 
 (2)   Mosaic may petition FDEP in writing, with a copy provided to EPA, to extend its zone of discharge
for certain specified water quality parameters. FDEP, in consultation with EPA and pursuant to Florida Administrative Code 62-520.470, Modification Procedures for Zones of Discharge or Monitoring Requirements, shall approve such extension if Mosaic
affirmatively demonstrates that conditions (a) through (d) below are met: 

(a)        The discharge shall not significantly impair any designated use of the receiving ground
water, or surface water; 
 (b)        The discharge shall not in the foreseeable future result in a
violation of applicable ground water standards in a currently used source of drinking water outside the zone of discharge; 

(c)          The discharge shall not prevent persons within the proposed zone of discharge
from enjoying the reasonable and beneficial use of their property; and 
 (d)          The
economic and social benefits of a zone of discharge extending beyond the property boundary outweigh the economic, environmental, and social costs resulting from the extended zone of discharge, taking into account the feasibility of preventative
measures or corrective actions. 
 (e)   Mosaic shall provide a copy of the petition to the property owners of the property
underlain by the proposed extended zone of discharge by certified mail return receipt requested within 10 Days from submitting the petition to FDEP and EPA. A copy of each certified mail return receipt shall be provided to the appropriate permitting
program in FDEP District office where the permit was issued. 
 (f) If FDEP determines that other information is necessary to ascertain if an extension to
the zone of discharge is warranted, Mosaic must submit such additional information upon request. 
 Mosaic also shall provide any such additional information
requested by EPA. 
 (3) Nothing in this Section shall limit or affect EPA’s assertion of its residual authorities to disapprove a revision or
modification to a zone of discharge, notwithstanding approval by FDEP. 

  
 12 

Appendix B: Groundwater and Zone of Discharge Requirements 

Table of Contents

 EPA shall provide notice to Mosaic within 90 Days of FDEP approval if EPA does not concur with that decision.

 C. Zone of Discharge Monitoring Requirements

 (h) The costs of Corrective Action Work; and 

(i)  A comparison of the clean up or other Corrective Actions Work costs with the benefits to the public of such Corrective Action Work. 

(4) If requested by FDEP and/or EPA, Mosaic will provide within thirty (30) Days, unless directed otherwise, any additional information or data needed so
as to aid FDEP and/or EPA in making its Corrective Action Work assessment. 
 (5) After Mosaic submits the Corrective Action Plan, Mosaic shall perform the
Corrective Action Work pursuant to Attachment A, Paragraph 18, including Mosaic’s submission of a Corrective Action Measures Evaluation Report and a Corrective Action Certification Report in accordance with Paragraph 18. 

 
  
  

 

1 For facilities where the MCL is the most stringent standard for individual contaminants, if the Natural
Background exceeds the MCL, representative Natural Background will be the default Groundwater standard, unless Florida law or the Facility permit is more stringent than Natural Background for that contaminant, in which case Florida law or the
Facility permit will provide the appropriate standard for that contaminant.

design safety factor and this alternate design safety factor has been approved by FDEP and/or EPA. 
 (2) Within nine (9) months of a final
determination that a Perimeter Dike’s safety and stability cannot be certified in accordance with (1)(b)(iii) of this Section, the owner/operator shall submit to the FDEP and/or EPA for approval, a proposal to upgrade or retrofit the
Perimeter Dike to comply with the requirements of II.(1)(b) of this Attachment, or to take the Perimeter Dike out of service as soon as practicable but no later than ninety (90) days after a final determination that the Perimeter Dike’s
safety and stability cannot be certified and that the Perimeter Dike cannot or will not be upgraded or retrofitted to comply with the requirements of II(1)(b). 

(3) The owner/operator of any Perimeter Dike in need of upgrade, retrofit, or de-servicing, shall implement, within six (6) months of the FDEP’s
and/or EPA’s approval of the proposal submitted in accordance with (2), above, interim measures recommended by a Third-Party Engineer that will ensure the safety and stability of the Perimeter Dike until such time as it is upgraded or
retrofitted or taken out of service. These interim measures must be submitted to the FDEP and/or EPA for approval. 
 (4) At the time of the
assessment performed pursuant to (1)(b) or (1)(c) of this Section, a Third-Party Engineer shall also determine whether the existing system is equipped with Process Wastewater conveyance/containment capabilities that conform to the
following design requirements: 
 (a) Conveyance ditches, pumps, pipes, and hydraulic structures located within a Phosphogypsum Stack System
shall have adequate capacity to circulate the Process Wastewater stream(s), if applicable, and to contain or transfer runoff on the Process Watershed upstream of the water control structures resulting from a storm event generating a 100-year
rainfall in twenty-four (24) hours while maintaining at the same time the design Freeboard of the Perimeter Dike. If provisions are made to contain some or the entire storm surge resulting from such event within the Phosphogypsum Stack System
upstream from the conveyance system or water control structures, then the transfer capacity of the ditches, pumps, pipes, and related structures may be reduced accordingly. 

(5) Within one year of a final determination that a system does not meet the design criteria of

Table of Contents

 
(4)(a) of this Section, the owner/operator shall submit to the FDEP and/or EPA for approval, a proposal to modify the system to attain compliance. Such modification shall be completed as soon as
practicable, but not later than fourteen (14) months after the owner/operator receives all necessary governmental permits or other prior approvals, whichever shall later occur. 

III. Construction of New Perimeter Dikes 
 (1) Design

 (a) Site investigation. The general area desired for construction of a Perimeter Dike shall be carefully inspected by an Engineer prior
to selection of the exact location for the Perimeter Dike. Areas of uneven natural subsidence, sinkholes, pockets of organic matter, or other unstable soils shall be avoided, unless special provisions are made for their mitigation. 

(b) Soil testing.  A program of soil sampling and testing adequate to determine the characteristics of the foundation
material that will support the proposed Perimeter Dike and of the material to be used for construction of the Perimeter Dike shall be performed. Sampling shall include borings, test pits, or in-place samples from the associated exposed excavation
face. All borings and/or test pit explorations shall be logged using a recognized engineering soil classification system, with location and depths of all samples recorded on the Log. Tests to determine in-place densities, shear-strength, and
permeabilities of the foundation and embankment soils shall be performed. Tests on foundation soils shall be performed either on undisturbed samples or on the in-place soil. Tests on embankment soils shall be performed on samples remolded to the
densities and moisture contents to be used in construction. 
 (c) Cross section design: 

(i) The crest on the top of the Perimeter Dike shall be graded toward the Inside or the Outside slope. If the Perimeter Dike exceeds ten
(10) feet in height and crest runoff is directed toward the Outside slope, runoff controls shall be used to protect the Outside slope against erosion. Both Inside and Outside slopes shall be no steeper than two and one-half
(2.5) horizontal to one (1.0) vertical. Seepage control shall be provided by means of a Liner constructed in accordance with Section VI: Construction Requirements for New Phosphogypsum Stack Systems or Lateral Expansions of Existing
Phosphogypsum Stack Systems, of this Attachment, placed on the Inside slope of the Perimeter Dike. 
 (d) Freeboard provisions: 

(i) The design Freeboard of an above-grade Perimeter Dike shall not be less than five (5) feet unless a design Freeboard of less than
five (5) feet is justified based on results of seepage and stability analyses and Wave Run-up analyses. However, in no event shall the design Freeboard of an above-grade Perimeter Dike be less than three (3) feet. 

(e) Design factors of safety and slope stability of Perimeter Dikes: 

(i) Stability analysis. A seepage or flow net analysis shall be made, when 

  
 21 

Attachment C: Phosphogypsum Stack System Construction and Operation Requirements 

Table of Contents

 
applicable, for use in the stability analysis. The stability analysis shall consider the minimum fluid level as well as the fluid level at the design Freeboard on the upstream slope of the
Perimeter Dike, and possible fluctuations of the tail water level. 
 (ii) Design safety factors for Perimeter Dikes – The Engineer
shall use the following minimum safety factors for Perimeter Dikes: 1.75 for horizontal shear at base of fill; 1.5 for horizontal shear within the fill due to seepage through the outer face; 1.5 for horizontal shear or circular arc failure through
the foundation soils; 1.5 for protection against shear failure of any circular arc in either Inside or Outside slope. It is imperative that water pressure distribution be included in the analyses. 

(2) Site preparation. In accordance with specifications provided by the Engineer, ground that will become the foundation of Perimeter Dikes shall be stripped
of vegetation and organic detritus or residue, including muck, mud, slimes, or other material which would flow or undergo excessive consolidation under heavy loading. All earth foundation surfaces on which fill is to be placed shall be scarified or

water balance targets, the owner/operator must provide reasonable assurance that additional Process Wastewater consumption or management items, not already included as outputs in the water balance analysis, are readily available and capable of
maintaining these water balance targets. Use of available storage within an Auxiliary Holding Pond, up to its Maximum Design Levels, may be used to provide this assurance. 

(c) If the water balance indicates that at any time during the five (5)-year modeling period that Process Wastewater levels, in conjunction
with additional available Process Wastewater consumption or management items will not meet the water balance targets, the owner/operator must provide additional Process Wastewater consumption or management items, and submit an alternatives plan and
implementation schedule for approval by the FDEP and/or EPA for the additional consumption or management measures within ninety (90) days of submittal of the water balance analysis. The plan and schedule shall include, at a minimum, the
following elements: 
 1. A listing and description of the additional Process Wastewater consumption or management items to be evaluated,
including the identification of items that can be rapidly implemented to achieve the water balance targets; 
 2. A listing of interim
measures that can be implemented to prevent an unpermitted release of Process Wastewater in the event that actual rainfall events contribute to Process Wastewater levels exceeding Maximum Design Levels; and 

3. A proposed schedule for the evaluation, selection, engineering, design, and construction, installation or implementation for the items and
interim measures needed to increase water consumption, reduce inventories, or any combination of such actions that will result in achievement of the water balance targets.

a.         The initial Cost Estimate, except as set out below in Paragraph 1.b for Financial
Assurance being provided pursuant to Paragraph 10.a(1)(c), shall include a detailed written Cost Estimate for Phosphogypsum Stack System Closure and Long Term Care for each Facility, including but not limited to the cost of cover material, topsoil,

provided in Paragraph 1.c., below. Defendant shall include as part of its initial Cost Estimate the information specified in Attachments B and C of this Appendix. 

b.         If Defendant is providing Financial Assurance in accordance with Paragraph 10.a(1)(c),
then the initial Cost Estimate shall consist of a written Cost Estimate in the form specified in Attachments B and C. The Cost Estimate shall be calculated based on the December 2011 configuration of the Phosphogypsum Stack System(s) at the
Operating Facilities and Closing Facilities (“Operating and Closing Facilities”) with the configuration of the Phosphogypsum Stack Systems for the Operating and Closing Facilities being updated every five (5) years thereafter (e.g.,

of this Paragraph 1.c. are met, provide a Cost Estimate that includes a cost for soil from a borrow area at the Facility, based on information provided by the Defendant describing the soil borrow areas to be used (e.g., location), in lieu of the
cost to obtain soil from a Third Party. In that event, Defendant agrees that the United States and FDEP, in addition to their right to Financial Assurance as set forth in the Consent Decree, shall have the same legal right of access to and use of
such soil, and any equipment necessary to access and process such soil, as Defendant would have. Defendant shall confirm with its Updated Cost Estimate submittal required under Paragraph 4, below, that the United States and FDEP continue to have a
right to access and use the soil, that the soil available is sufficient for closure of the Phosphogypsum Stack System, and that Defendant knows of no reasons as to why the United States and FDEP, or their representatives, could not have access to
and use of the borrow area(s) and soil. If, for any reason, Defendant or EPA determines that such access cannot be had, or that the available soil in the borrow area is insufficient for closure of the Phosphogypsum Stack System, then Defendant in
its next annual Updated Cost Estimate or ninety (90) Days prior to Phosphogypsum Stack System Closure shall submit to EPA a revised Cost Estimate recalculating the soil cost either: (i) based on the cost of soil from a substitute borrow
area at the Facility; (ii) based on the cost of soil and transportation from a substitute borrow area in the vicinity of the Facility on property owned by Mosaic Fertilizer, LLC; or (iii) if such substitute borrow area is not available, as
a cost of a Third Party buying the soil for closure of the Phosphogypsum Stack System, and shall provide any additional or alternative Financial Assurance necessary to cover this cost. If Defendant has established Financial Assurance pursuant to
Paragraph 10.a(1)(c) of this Appendix, then such additional cost shall be covered by the Corporate Guarantee until such time as the trust fund is fully funded. Nothing in this Paragraph 1.c. shall be construed as transferring to the United States,
FDEP or their representatives any obligation that Defendant may have under the law, including permit requirements, to properly manage, close and/or remediate the soil borrow areas, or otherwise creating such obligations for the United States and/or
FDEP, or their duly designated representatives. 
 d.         Lime treatment sludge ponds that
are not part of the Defendant’s Phosphogypsum Stack System, and that are included in a National Pollutant Discharge Elimination System (NPDES) permit issued by FDEP, shall not be incorporated into the Cost Estimate and shall not be required to
be covered by Financial Assurance under this Appendix. 
 2.        Each Cost Estimate shall be calculated as
follows:

Mosaic Appendix 2 

Table of Contents

 a.         In Current Dollars if Defendant provides
Financial Assurance under Section III.A (Type A Financial Assurance), below; or 
 b.         In
Current Dollars for Phosphogypsum Stack System Closure and using NPV for Long Term Care if Defendant provides the Financial Assurance pursuant to Section III.B (Type B Financial Assurance), below. NPV shall be calculated using the 30-Year Treasury
Constant Maturity Rate, averaged for the previous twelve (12) months (using the average spot rate for each month) from the date of the annual Cost Estimates, and discounted over the time period for which Long Term Care is required. 

3.        Defendant shall not include in any Cost Estimate any credit for salvage value or a zero cost for handling
hazardous waste with potential future value, as set forth in 40 C.F.R. § 264.142(a)(3)&(4). 

4.        Defendant shall submit the Updated Cost Estimate, together with supporting documentation, to EPA in the
following manner: 
 a.         Defendant shall submit annually to EPA an Updated Cost Estimate
reflecting inflationary adjustments to the initial Cost Estimate or prior Updated Cost Estimate, except as set forth in Paragraph 4.c, below. Such adjustment may be made by either method in Paragraph 4.a.(1) or 4a.(2) below, except as otherwise
required in this Appendix: 
 (1) Recalculating the costs, in Current Dollars (i.e., OSWER Directive No. 9476.00-5, Section 4.4.1);
or 
 (2) Using an inflationary factor derived from the most recent Implicit Price Deflator for the Gross National Product published by the
U.S. Department of Commerce in its Survey of Current Business, in the manner as specified by 40 C.F.R. §§ 264.142(b) and 264.144(b). If the Cost Estimate is due by the end of February, the Defendant shall: (i) use the Implicit
Price Deflator for the Gross National Product published for Q1, Q2 & Q3 of the prior year, calculate the change in the Deflator between Q1 and Q2, and the change in Deflator between Q2 and Q3, take the average of these values, and add this
average to the Q3 Deflator to impute a Q4 Deflator; or (ii) if the Implicit Price Deflator for the Gross National Product has not been published for Q3 of the prior year by February 10 of the following year, Defendant shall calculate the
change in the published Deflator between Q1 and Q2, adding this value both to the Deflator for Q2 to impute a Q3 Deflator and to the imputed Q3 Deflator to impute a Q4 Deflator. If Defendant calculates imputed Deflators by using an average of the
change in Deflators from prior quarters, because the actual Implicit Price Deflator for Q3 or Q4 were not then available, annual inflationary adjustments in subsequent years shall be based on the actual Implicit Price Deflator, as and when published
values become available. An example of the inflationary factor calculation is provided in Attachment B of this Appendix. 

b.         Defendant shall submit for the Updated Cost Estimate, unless required to provide an
Updated Cost estimate pursuant to Paragraph 4.c., below, a supplement to the Initial Closure Plan updating any new information (e.g., revised closure schedule) and Attachments B and C of this Appendix, except that if Defendant is providing Financial
Assurance pursuant to Paragraph 10.a.(1)(c), then Defendant shall provide only Attachment B. 

c.         Defendant shall: 

(1) If providing Financial Assurance other than pursuant to Paragraph 10.a.(1)(c), submit every five (5) years for the annual Updated Cost
Estimate, a Cost Estimate with supporting documentation and an updated Initial Closure Plan (if needed), reflecting cost

adjustments (e.g., revised treatment protocols, additional studies; treatment costs, material and labor cost increases, etc.) as specified in Paragraph 4.c.(3), below. Defendant shall provide the
Updated Cost Estimate and associated documentation five (5) years after the submittal of the initial Cost Estimate (pursuant to Paragraph 1.a. of this Appendix). Defendant shall also provide such an Updated Cost Estimate for a Facility:
(i) in the event of a re-evaluation of when the manner and extent of the operation of the Phosphogypsum Stack System makes the Phosphogypsum Stack System Closure and Long Term Care the most expensive; (ii) with the submittal of the
Permanent Phosphogypsum Stack System Closure Plan as specified in Appendix 1, Attachment D of the Consent Decree; and (iii) thirty (30) Days prior to a Facility transfer with the information requested pursuant to Paragraph 35 of this
Appendix. 
 (2) If providing Financial Assurance pursuant to Paragraph 10.a.(1)(c), submit every five (5) years for the annual Updated
Cost Estimate, (i) an updated Initial Closure Plan, including detailed Cost Estimate information consistent with the level of detail in Section 3 (and associated Tables) and Attachment 1 (and associated Tables) of the draft 2012 Initial
Closure Plans provided by Defendant to EPA and FDEP prior to the lodging of the Consent Decree and (ii) Attachments B and C. The updated Initial Closure Plan and Updated Cost Estimate shall reflect cost adjustments (e.g.,(as applicable),
revised treatment protocols, additional studies; revised programmatic and administrative needs; treatment costs, material, and labor cost increases; etc.) and the configuration of the Phosphogypsum Stack System as of December of the prior year
(e.g., stack height, acreage to be closed, number of side slope and/or toe drains, volume of process wastewater, leachate, and sludge (within the Phosphogypsum Stack System) to be managed, updated aerial photographs, updated engineering drawings of
the Phosphogypsum Stack System, any new components (e.g., cooling pond, ditches)). Such costs shall be adjusted as specified in Paragraph 4.c.(3) below. Defendant shall provide the Updated Cost Estimate and Initial Closure Plan under this Paragraph
in 2017, with subsequent Updated Cost Estimates and updated Initial Closure Plans every five (5) years thereafter (e.g., 2022, 2027). Defendant shall also provide such an Updated Cost Estimate for a Facility: (i) at least sixty
(60) Days prior to the Defendant constructing a lateral expansion at a Facility referenced in Paragraph 29.b; (ii) with the submittal of the Permanent Phosphogypsum Stack System Closure Plan as specified in Appendix 1, Attachment D of the
Consent Decree; and (iii) thirty (30) Days prior to a Facility transfer with the information requested pursuant to Paragraph 35 of this Appendix, unless such Updated Cost Estimate has been performed for such Facility within the prior two
(2) years. The submittal of an Updated Cost Estimate under Paragraph 4.c.(2)(i)&(ii), above, shall not alter the five (5)-year schedule for receipt of an Updated Cost Estimate under this Paragraph. 

(3) An Updated Cost Estimate submitted under this Paragraph 4.c. shall be adjusted by recalculating the costs, in Current Dollars, as set forth
in Paragraph 4.a.(1), above. 
 (a) In the event a specific cost needed to prepare the Updated Cost Estimate has been updated
pursuant to Paragraph 4.a.(1), above, within one (1) year, Defendant may adjust that specific cost pursuant to Paragraph 4.a.(2), above. 

(b) In the event a specific cost needed to prepare the Updated Cost Estimate has not been updated pursuant to Paragraph
4.a.(1), above, within one (1) year and is not otherwise available, then Defendant may utilize the most recent update of that specific cost, and adjust that prior cost pursuant to Paragraph 4.a.(2), above, provided that Defendant identifies the
specific cost and includes a brief explanation for adjusting the cost pursuant to Paragraph 4.a.(2), above.

 d.         If providing Financial Assurance under
Section III.B (Type B Financial Assurance), in addition to Paragraphs 4.a.-4.c., Defendant shall submit with the initial Cost Estimate and Updated Cost Estimate the calculation and documentation for the average discount rate used for the NPV. In
addition, the inflation factor to be used to inflate Long Term Care costs for purposes of deriving the NPV of Long Term Care shall be the mathematical average of the calculated inflation factors for each year over a five (5)-year period. Each
year’s calculated inflation factor shall be the product of dividing the GDP Deflator for the relevant year by the GDP Deflator for the year immediately prior, beginning with the first year in which the GDP Deflator is an estimate and for each
year thereafter until the fifth year. The Gross Domestic Product (GDP) Deflator is as specified in the “GDP (Chained) Price Index” of the Gross Domestic Product Deflators Used in the Historic Tables (Table 10.1), published by
the Office of Management and Budget (“OMB”). If the OMB publication is unavailable, in a written agreement not subject to Court approval under Section XVIII (Modification) of the Consent Decree, EPA and Defendant shall identify another
method to derive the inflation factor. 
 e.         Defendant shall submit the Updated Cost
Estimate, in accordance with this Paragraph, sixty (60) Days prior to the Anniversary Date of the establishment of the Financial Mechanism, except if otherwise provided herein. If more than one Financial Mechanism is being used to establish
Financial Assurance, the Updated Cost Estimate shall be submitted sixty (60) Days prior to the earliest Anniversary Date, for a given calendar year, of a Financial Mechanism. Notwithstanding the foregoing, if Defendant is establishing Financial
Assurance pursuant to Paragraph 10.a(1)(c), Defendant shall submit Updated Cost Estimate(s) pursuant to this Paragraph 4.e. as follows: (1) Updated Cost Estimate required pursuant to Paragraph 4.c. by March 31, 2017, and by March 31
every five (5) years thereafter; and (2) Updated Cost Estimate required by Paragraph 4.a. by the end of February in 2018 and in all years thereafter except when the Updated Cost Estimate is provided under 4.e.(1), above. 

5.        Notwithstanding the provisions of Section XII (Information Collection and Retention) of the Consent Decree,
Defendant shall maintain, or have electronic access to (such that upon request the information can be readily downloaded and printed), at the Facility for the duration of this Consent Decree the Updated Cost Estimate. 

III.  Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care 

6.        Within thirty (30) Days of the Effective Date of the Consent Decree or within thirty (30) Days of
EPA’s approval of Defendant’s initial Cost Estimate, whichever is later, and on the first Anniversary Date and annually thereafter, Defendant’s CFO shall provide to EPA an originally signed CFO Certification, together with supporting
documentation, confirming that it has established Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care, in an amount no less than the Total Florida Cost Estimate and pursuant to the requirements of either Section III.A (Type
A Financial Assurance) or Section III.B (Type B Financial Assurance), of this Appendix, at Defendant’s election. If Defendant is providing Financial Assurance pursuant to Paragraph 10.a(1)(c), Defendant’s CFO shall provide a CFO
Certification in accordance with Paragraph 29.d of this Appendix within fifteen (15) Days after such Financial Assurance has initially been provided.

 7.        Once Defendant establishes either Section III.A (Type A
Financial Assurance) or Section III.B (Type B Financial Assurance) (hereinafter also known as Section III.A or Section III.B, respectively) for Phosphogypsum Stack System Closure and Long Term Care, it shall maintain such Financial Assurance
pursuant to the requirements of Section III.A or Section III.B, as applicable, unless EPA approves a request to provide Financial Assurance pursuant to the other Section (i.e., Section III.A or Section III.B, as applicable). If Defendant wishes to
request such a change in its Financial Assurance as specified above, then Defendant shall submit to EPA for approval: (a) an originally signed CFO Certification, together with supporting documentation, explaining in detail the reasons for the
request; and (b) proposed Financial Assurance, compliant with the applicable Section III.A or Section III.B requirements, that can become effective within thirty (30) Days of EPA’s approval. Defendant shall not cancel its existing
Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care until it receives EPA’s written approval of Defendant’s request and the alternate Financial Assurance is in effect (e.g., trust fund is funded; insurance policy
is in effect). If Defendant is providing Section III.A (Type A Financial Assurance) pursuant to Paragraph 10.a.(1)(c), a request to substitute another form of Section III.A (Type A Financial Assurance), or substitute Section III.B (Type B
Financial Assurance), EPA’s approval of such a request, shall not release the Defendant from its obligation to maintain the existing Florida Phosphogypsum Trust Fund. EPA’s determination whether to approve Defendant’s request to
provide alternate Financial Assurance may take into account Defendant’s ability to promptly comply with the requirements of the other of Section III. A or Section III.B, its financial stability, and other such factors and proposals as Defendant
may advance in requesting the change.

 10.      Defendant shall choose from the
Financial Mechanisms specified in 40 C.F.R. §§ 264.143(a)-(f) and 264.145(a)-(f) to establish Section III.A (Type A Financial Assurance), provided that, if Defendant is using Third-Party Mechanisms (a trust fund, letter of
credit, surety bond, or insurance), the Trustee of any trust fund, or the provider of any letter of credit, surety bond, or insurance shall not be a Related Party to Defendant. Defendant shall word the Financial Mechanism as specified in 40 C.F.R.

e.         For the corporate financial test, Defendant (including Defendant’s Guarantor),
shall comply with 40 C.F.R. §§ 264.143(f) and 264.145(f), except that: 
 (1) In lieu of complying with 40 C.F.R. §§
264.143(f)(1)(ii)(A) and 264.145(f)(1)(ii)(A), Defendant shall use the current rating of either Standard & Poor’s (“S&P”) Long-Term Issuer Credit Rating or Moody’s long-term Corporate Family Rating, which assesses a

shall document its satisfaction of the corporate financial test by submitting to EPA within ninety (90) Days after the close of Defendant’s fiscal year, for each year Defendant is providing a Self-Assurance Mechanism: 

(a) A letter signed by Defendant’s CFO worded exactly as specified in Form 4-A, Attachment D of this Appendix (“CFO

(including attachments and exhibits) from Defendant’s CFO and Defendant’s Independently Audited, year-end financial statements for the last fiscal year, including all attachments. Where differences or discrepancies exist between
Defendant’s CFO Letter and Defendant’s Independently Audited year-end financial statements, the report of procedures and findings will reconcile any differences or discrepancies between the values or information represented in
Defendant’s CFO Letter and Defendant’s Independently Audited financial statements. Procedures to be performed by the independent CPA shall be in accordance with AT Section 201. 

(5) In addition to complying with 40 C.F.R. §§ 264.143(f)(6) and 264.145(f)(6), if Defendant determines at any time during the fiscal
year that it no longer meets or will not meet the requirements of this Paragraph 10.e, Defendant shall provide alternate Financial Assurance pursuant to the requirements of Section III.A (Type A Financial Assurance) and Section VII (Temporary
Non-Compliance) of this Appendix. If EPA determines that Defendant has failed to provide alternate Financial Assurance as required by this Paragraph 10.e.(5), such determination by EPA is not subject to dispute resolution pursuant to Section XI
(Dispute Resolution) of the Consent Decree, and is not subject to judicial review. 
 (6) Within thirty (30) Days of notice from EPA
that EPA, pursuant to 40 C.F.R. §§ 264.143(f)(7) and 264.145(f)(7), no longer believes that Defendant meets the requirements of the corporate financial test criteria of Paragraph 10.e., or that EPA disallows the use of the corporate
financial test based on qualifications in the opinion expressed by the independent CPA as set out in 40 C.F.R. §§ 264.143(f)(8) and 264.145(f)(8), Defendant shall establish alternate Financial Assurance as required by 40 C.F.R.
§§ 264.143(f)(7)&(8) and 264.145(f)(7)&(8) pursuant to this Section III.A (Type A Financial Assurance). Defendant’s failure to timely establish alternate Financial Assurance is not subject to Section VII (Temporary
Non-Compliance) of this Appendix. EPA’s determination to disallow the Financial Assurance provided by the Self-assurance Mechanism based on the Defendant’s (or Defendant’s Guarantor’s) independent CPA’s adverse or disclaimer
opinion based on examination of the financial statement’s shall be subject to dispute resolution under Section XI (Dispute Resolution) of the Consent Decree, but shall not be subject to judicial review.

Section III.B (Type B Financial Assurance) in an amount at least equal to the Total Florida Cost Estimate. 
 13.      The
options and requirements for Type B Financial Assurance depend upon Defendant’s threshold rating, which shall be based on: (a) current S&P Long-Term Issuer Credit Rating of AAA through BB-; (b) current Moody’s Corporate
Family Rating of Aaa though Ba3; or (c) an equivalent current rating from an NRSRO that assesses a company’s capacity to meet its long-term (greater than one (1) year) financial commitments, as they come due. If Defendant has more
than one rating, it shall use the lowest rating to determine its threshold rating. 
 14.      A Defendant that qualifies to
use a Self-Assurance Mechanism based on its threshold rating and Attachment E shall use only one Self-Assurance Mechanism. When required under Attachment E to provide a Third-Party Mechanism in combination with a Self-Assurance Mechanism, Defendant

 (d) A report of procedures and findings from Defendant’s independent CPA,
resulting from an agreed-upon procedures engagement performed in accordance with the AICPA Statement on Standards for Attestation Engagements, AT Section 201 - Agreed Upon Procedures
Engagements (including AICPA related attestation interpretations), as updated, that describes the procedures performed and related findings, including whether or not differences or discrepancies were found in the comparison of financial
information set out in the letter (including attachments and exhibits) from Defendant’s CFO and Defendant’s Independently Audited, year-end financial statements for the last fiscal year, including all attachments. Where differences or
discrepancies exist between Defendant’s CFO Letter and Defendant’s Independently Audited year-end financial statements, the report of procedures and findings will reconcile any differences or discrepancies between the values or information
represented in Defendant’s CFO Letter and Defendant’s Independently Audited financial statements. Procedures to be performed by the independent CPA shall be in accordance with AT Section 201. 

(4) In addition to complying with 40 C.F.R. §§ 264.143(f)(6) and 264.145(f)(6), if Defendant determines at any time during the fiscal
year that: 
 (a) It no longer meets or will not meet the requirements of this Paragraph 15.e. (including the loss of a
threshold rating except as provided by Paragraph 15.e.(2)(a), above), Defendant shall within ten (10) Days send written notice to EPA of this determination, by certified mail, stating the basis for such a determination. If Defendant cannot
re-establish compliance with the requirements of this Paragraph 15.e. pursuant to Section VII (Temporary Non-Compliance) and/or Section VIII.B (Compliance Schedule: Type B) of this Appendix, the Defendant, within thirty (30) Days of its
notice to EPA as specified above, shall provide alternate Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care pursuant to Paragraph 18, below. 

(b) Its threshold rating requires Defendant to change from one set of corporate financial test criteria under Paragraph
15.e.(2), above, and Attachment E (e.g., CFT Criteria A) to a more stringent set of corporate financial test criteria (e.g., CFT Criteria C), Defendant shall notify EPA within ten (10) Days of the change in corporate financial test criteria and
within thirty (30) Days of such notice shall submit to EPA a revised corporate financial test or Corporate Guarantee based on the most recent evaluation conducted under Paragraph 15.e.(6)(c), below, demonstrating compliance with the more
stringent corporate financial test criteria. To the extent necessary, Defendant shall at the same time make a contribution to the Third-Party Mechanism to comply with the minimum threshold amount specified in
the corporate financial test requirements in Paragraph 15.e.(2), above. 
 (c) If EPA determines that Defendant has failed to
provide alternate Financial Assurance as required, or complied with Paragraphs 15.e.(4)(a) and (4)(b), such determination by EPA is not subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree, and is not
subject to judicial review. 
 (5) Within thirty (30) Days of notice by EPA that EPA, pursuant to 40 C.F.R. §§ 264.143(f)(7)
and 264.145(f)(7), no longer believes that Defendant meets the corporate financial test criteria in Paragraph 15.e.(2), above, or that EPA disallows the use of the corporate financial test based on qualifications in the opinion expressed by the
independent CPA as set forth in 40 C.F.R. §§ 264.143(f)(8) and 264.145(f)(8), Defendant shall provide alternate Financial Assurance as required by 40 C.F.R. §§ 264.143(f)(7)&(8) and 264.145(f)(7)&(8) pursuant to Paragraph
18 of this Appendix. Defendant’s failure to timely provide alternate Financial

Assurance is not subject to Section VII (Temporary Non-Compliance) of this Appendix. EPA’s determination to disallow the Financial Assurance provided by the Self-Assurance Mechanism based on
the Defendant’s (or Defendant’s Guarantor’s) independent CPA’s adverse or disclaimer opinion based on examination of the financial statement’s shall be subject to dispute resolution under Section XI (Dispute Resolution) of
the Consent Decree, but is not subject to judicial review. 
 (6) In addition to complying with 40 C.F.R. §§ 264.143(f) and
264.145(f), Defendant shall: 
 (a) If Defendant with an S&P rating of BB-, Moody’s rating of Ba3, or an equivalent
NRSRO rating, receives a negative outlook posted on one or more of its ratings, or receives a qualified opinion from an independent CPA, or is delisted from an Exchange for any reason other than: (i) Defendant’s decision to take the
company into private ownership, or (ii) a transaction which results in the acquisition of Defendant (or Defendant’s ultimate parent corporation) by another company subjecting Defendant to Section X (Business Transactions) of this Appendix,
then Defendant shall within ten (10) Days of such an event send written notice by certified mail of such event to EPA, and within thirty (30) Days of such notice shall provide an alternate form of Financial Assurance, in compliance with
Paragraph 18 of this Appendix. In the event that the delisting is due to Defendant’s decision to take the company into private ownership Defendant may continue to provide Financial Assurance using the Financial Mechanism(s) already in place if,
within twenty (20) Days of the delisting, it provides documentation to EPA from S&P, Moody’s or the NRSRO confirming that Defendant meets a current S&P Long-Term Issuer Credit Rating, Moody’s long-term Corporate Family Rating,
or equivalent current rating from an NRSRO, as specified in Paragraph 13 of this Appendix. 
 (b) If more than sixty percent
(60%) of Defendant’s tangible assets are in the form of one (1) or more note receivables from one (1) or more Related Parties, submit to EPA, when providing the information required by Paragraph 15.e.(3), above, and 40 C.F.R.
§§ 264.143(f)(5) and 264.145(f)(5), an originally signed CFO Certification by the Defendant’s CFO together with a list of each note receivable, the name of the Related Party and a description (along with any necessary documentation)
of the Related Party’s financial strength, to demonstrate that each Related Party maintains the financial strength to meet its obligation to the Defendant. 

(c) On a quarterly basis prepare and use financial statements (including balance sheets, income statements, and cash flow
statements), reviewed by an independent CPA, to evaluate Defendant’s ability to meet the criteria of the corporate financial test. To meet the criteria involving rolling averages, the averages shall be based on the results as of the end of the
same quarter for the prior years (i.e., a three (3)-year rolling average evaluated at the end of the first quarter for Year X shall include the results from the first quarter of Year X-2 and X-1). In addition, Operating Cash Flow for this evaluation
shall be based on the results from the most recent four (4) quarters (i.e., for a first quarter analysis, the Operating Cash Flow shall be based on the results from the second quarter of the previous year through the first quarter of the
current year). The same adjustment shall be made for the OCF metric for prior periods if the criteria involve the use of a rolling average. 

(d) If Defendant with a S&P rating of BBB- through BB, a Moody’s rating of Baa3 through Ba2, or an equivalent rating
from an NRSRO receives a negative outlook posted 

  
 23

financial test based on the most recent evaluation conducted under Paragraph 15.e.(6)(c), above. 

f.         For the Corporate Guarantee, Defendant shall comply with 40 C.F.R. §§
264.143(f)(10) and 264.145(f)(11), and shall meet the requirements specified below, if applicable. 
 (1) Defendant may use a Non-U.S.
Corporation as a Guarantor only if the following conditions are met: (a) Non-U.S. Corporation meets the requirements of Paragraph 10.f. of this Appendix, and (b) Non-U.S. Corporation has a current rating for either the S&P long-term
issuer credit rating of AAA through BBB, Moody’s long-term corporate family rating of Aaa though Baa2 or an equivalent rating from an NRSRO that assesses a company’s capacity to meet its long-term (greater than one (1) year) financial
commitments, as they come due. 
 (2) Defendant shall use the exact wording as specified in Form 5-A, Attachment D of this Appendix, for the
Corporate Guarantee. The certified copy of the Corporate Guarantee must accompany the items sent to EPA, in accordance with Section XV (Notices) of the Consent Decree, as specified in Paragraph 15.e.(3) of this Appendix. 

16.      Defendant may submit annually, for EPA approval, a request to use a letter of credit, surety bond guaranteeing payment,
or insurance in lieu of the trust find required under Paragraph 14, above. Defendant shall include in its request documentation demonstrating compliance with Financial Assurance under this Subsection III.B. Defendant may not rely upon the
letter of credit, payment surety bond, or insurance to establish compliance with this Appendix until EPA has approved the Third-Party Mechanism. Defendant shall comply with the letter of credit, payment surety bond, or insurance requirements of
Paragraph 15 of this Appendix, as applicable. Defendant shall also demonstrate compliance with Paragraph 11 of this Appendix. EPA’s determination whether or not to accept Defendant’s request is subject to dispute resolution pursuant to
Section XI (Dispute Resolution) of the Consent Decree, but is not subject to judicial review. 
 17.      Defendant may
submit annually, for EPA approval, a request to use multiple Third-Party Mechanisms (i.e., trust fund, letter of credit, surety bond guaranteeing payment, and insurance) in conjunction with a Self-Assurance
Mechanism, together with supporting documentation, to demonstrate Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care. Defendant shall not rely upon the additional Third-Party Mechanism to establish compliance with this
Consent Decree until EPA has approved the additional Third-Party Mechanism. Defendant shall also demonstrate compliance with Paragraph 11 of this Appendix. EPA’s determination whether or not to accept Defendant’s request is subject to
dispute resolution under Section XI (Dispute Resolution) of the Consent Decree, but is not subject to judicial review. 

18.      If Defendant at any time becomes ineligible to rely on a Self-Assurance Mechanism pursuant to this Section III.B,
and cannot re-establish such eligibility pursuant to Section VII (Temporary Non-Compliance) and/or Section VIII.B (Compliance Schedule: Type B) of this Appendix, then Defendant shall establish alternate Financial Assurance based on Current Dollars
by: (a) maintaining the existing Financial Assurance in the trust fund (or as approved, other 

  
 24 

Mosaic Appendix 2

Third-Party Mechanism) as established pursuant to Paragraph 14; (b) providing additional Financial Assurance using Third-Party Mechanism(s) pursuant to Paragraphs 10.a-d, except for
Paragraph 10.a.(1)(c); and (c) meeting the requirements of Paragraph 11 of this Appendix when providing more than one Financial Mechanism. If Defendant meets the above requirements and EPA approves the alternate Financial Assurance (including
the termination of a Corporate Guarantee if provided), Defendant does not need to meet the requirements of Paragraph 15 of this Appendix. Defendant shall continue to be subject to Section III.B (Type B Financial Assurance), as set forth in this
Paragraph 18, unless EPA approves a request to change to Section III.A (Type A Financial Assurance) pursuant to Paragraph 6 of this Appendix. 

19.      If the Total Florida Cost Estimate at the commencement of Defendant’s fiscal year is less than or equal to the
value of the following Third-Party Mechanism(s), trust fund or insurance, then Defendant, may draw upon the Third-Party Mechanism(s) to pay for Phosphogypsum Stack System Closure and Long Term Care. Otherwise, Defendant shall first draw upon the
resources of the Self-Assurance Mechanism before drawing upon a Third-Party Mechanism to pay for Phosphogypsum Stack System Closure or Long Term Care. If EPA approves the use of multiple Third-Party Mechanisms under Paragraph 17, above, EPA will
designate the priority for drawing on the Third-Party Mechanisms and EPA’s designation shall not be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree, and shall not be subject to judicial review.

21.      Defendant shall, within thirty (30) Days of receiving approval by EPA of any Risk Assessment Plan or Interim
Measures Plan required pursuant to Paragraphs 17 or 19 in Attachment A of Appendix 1 of the Consent Decree, provide a detailed written Corrective Action Cost Estimate for the work required under the applicable Plan (“Plan Work”). Defendant

configuration (i.e., fully-engineered and constructed) upon and in accordance with any requisite approvals by FDEP pursuant to the laws and regulations of Florida. Nothing in this Paragraph or in
the Consent Decree shall be construed to limit, alter or supersede the permitting and approval authorities of FDEP with respect to the permitting or timing and conditions of the Planned Expansion(s). 

(2) The Planned Expansion shall be a Covered Expansion if it meets either of the following criteria, below, to be determined at the time the
Planned Expansion(s) is fully engineered and the information required by Paragraph 29.b.(3), below, has been submitted (the “Determination Date”): 

(a) The Total Phosphogypsum Volume3 in the Phosphogypsum Stack System
anticipated at the Determination Date (calculated pursuant to Paragraph 29.b.(3), below) is not more than two point five percent (2.5%) greater than the Total Phosphogypsum Volume anticipated in 2015 (as specified in the Attachment G:
Baseline), and the anticipated Total Future Closure Area at the Determination Date (calculated pursuant to Paragraph 29.b.(3), below) is not more than three percent (3%) greater than the Total Future Closure Area anticipated in 2015 (as
specified in Attachment G: Baseline); or 
 (b) The sum of the following is not more than five percent (5%): 

(i) The percent (%) change between the Total Phosphogypsum Volume anticipated at the Determination Date (calculated
pursuant to Paragraph 29.b.(3), below) and the Total Phosphogypsum Volume anticipated in 2015 (as specified in the Attachment G: Baseline), and 

(ii) The percent (%) change between the Total Future Closure Area anticipated at the Determination Date (calculated
pursuant to Paragraph 29.b.(3), below) and the Total Future Closure Area anticipated in 2015 (as specified in the Attachment G: Baseline). 

(c) Defendant shall, in making the calculations required by Paragraph 29.b.(2)(b), above, substitute zero (“0”) for a
negative percentage that may be generated when comparing the Total Phosphate Volume or the Total Future Closure Area as of the Determination Date to the 2015 baseline. 

(3) Defendant shall submit to EPA information regarding the Planned Expansion(s) at the Operating Facilities as follows: 

(a) If Defendant has not provided the information regarding the Planned Expansion(s) at the Operating Facilities identified by
Defendant in 2015 using the form in Attachment G, prior to the Effective Date of the Consent Decree, then Defendant shall submit such information to EPA (the “Attachment G: Baseline”) within thirty (30) Days of the Effective Date of
the Consent Decree to use as a baseline in determining if the Planned Expansion(s) once fully engineered is a Covered Expansion. 

(b) Defendant shall submit updated information regarding the Planned Expansion using the form in Attachment G (the
“Attachment G: Updated”), within 45 (forty-five) Days of the time that a Planned Expansion has been fully-engineered. The information submitted shall be used to determine if the Planned Expansion as fully engineered is a Covered Expansion.
Attachment G: Updated shall include the following adjustments, if applicable:

 (i) If Defendant has not installed an intermediate liner as identified in the
2015 baseline as reflected in Attachment G: Baseline at the corresponding average stack elevation prior to activation of the Planned Expansion, then the Total Phosphogypsum Volume shall be revised in the Attachment G: Updated to account for the lack
of the intermediate liner by adding in the corresponding values of phosphogypsum volume deducted for that anticipated liner as previously calculated and reflected in the Attachment G: Baseline in the column labelled “Phosphogypsum Volume to be
Added if Intermediate Liner is Not Installed as Planned (acre-feet).” 
 (ii) If Defendant has, after 2015, either lined
or closed an isolated section of the Phosphogypsum Stack System or has installed an intermediate liner for such section that had not been identified in the 2015 Attachment G, the volume of phosphogypsum beneath the intermediate or other liner at the
time of liner installation may be reduced at the rate of eight percent (8%) annually for the period following the installation of the liner until the Determination Date, when calculating the Total Phosphogypsum Volume on the Updated Attachment
G. 
 (iii) If Defendant, after 2015, closes a portion of the stack top area or slope area earlier than scheduled to be
closed, the corresponding area(s) may be deducted from the Total Future Closure Area in the Updated Attachment G, provided there are no then-planned lateral or vertical expansions that would require re-activating the closed areas. 

(4) Notwithstanding the adjustments in Paragraph 29.b.(3)(b), above, a Planned Expansion shall not be considered a Covered Expansion if the
total area of the Planned Expansion as fully engineered exceeds the area of the Planned Expansion as specified in Attachment F (Figure F-2) and the Attachment G: Baseline (i.e., “Future Expansion Closure Area”) by more than eight percent
(8%). 
 (5) Defendant shall provide financial assurance under applicable State law and regulations for: 

(a) Any new Phosphogypsum Stack, new Phosphogypsum Stack System, or new expansion of a Phosphogypsum Stack System (i.e., any
lateral expansions, increased height above the design height as of 2015, new cooling pond or other form of expansion, in each case to the extent not identified in Attachment F); and 

(b) A Planned Expansion that exceeds the criteria for a Covered Expansion. The financial assurance shall be in an amount equal
to the difference in the (i) costs of Phosphogypsum Stack System Closure and Long Term Care between the Planned Expansion as anticipated in 2015 (see Attachment G: Baseline, “Planned Future Expansion Closure Area” and
“Planned Future Expansion Phosphogypsum Volume”) for the Operating Facility and (ii) the fully-engineered, actual build of the Planned Expansion, as permitted by FDEP, and as reflected in Attachment G: Updated (i.e., “Expansion
Closure Area” and “Expansion Phosphogypsum Volume”). This financial assurance, unless otherwise agreed to by FDEP in its sole discretion, is due within ninety (90) Days of submitting the Attachment G: Update. 

(6) Defendant shall not use the Financial Mechanisms demonstrating Financial Assurance under this Consent Decree (e.g., Financial Mechanisms
specified in Paragraph 29.a. of this Appendix) or that may be required in Paragraphs 27 or 32 of this Appendix, in establishing or

demonstrating compliance with any financial assurance required pursuant to any federal or State law or regulations. Defendant is not precluded from relying on such Financial Mechanisms in
satisfying any financial metric or test utilized for financial assurance when permitted under a federal or State law or regulation. 
 (7)
Defendant shall archive and maintain the Computer Aided Design (“CAD”) files, for the Operating Facilities, which contain the underlying information for the values specified in Attachment G: Baseline. Defendant shall maintain the CAD files
until Phosphogypsum Stack System Closure and Long Term Care, pursuant to a Permanent Closure Plan, has been implemented at the New Wales Facility. Defendant shall provide access to the CAD files, or provide the CAD files, within thirty
(30) Days of the EPA’s request. 
 c.        Defendant shall first draw upon its own
resources or a Guarantor’s resources (as set forth in Paragraph 32), before requesting any reimbursement or release from the Florida Phosphogypsum Trust Fund or any other Third-Party Mechanism established pursuant to this Section VIII to pay
for the Phosphogypsum Stack System Closure and/or Long Term Care at the Operating and Closing Facilities. If EPA approves additional Third-Party Mechanisms, as set out in Section III.A (Type A Financial Assurance) of this Appendix (e.g., insurance),
EPA will determine the priority for drawing on the Third-Party Mechanisms and such determination is not subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree and is not subject to judicial review. 

d.        Within forty five (45) Days of the trust fund being established and funded as set forth
in Paragraph 29.a., above, or by March 31 of the calendar year in which the trust fund is established and funded, whichever is later, and on or before the Anniversary Date in the following calendar year and annually thereafter, Defendant
shall provide to EPA an originally signed CFO Certification in the form attached hereto as Attachment A from the Defendant’s CFO together with supporting documentation, confirming that it has established Financial Assurance for Phosphogypsum
Stack System Closure and Long Term Care at the Operating and Closing Facilities in a total amount no less than the Total Florida Cost Estimate. The Anniversary Date under this Section XVIII.A. of the Appendix shall be March 31.

conform to the requirements of this Paragraph, 30.i. 
 j.        After the Florida Phosphogypsum
Trust Fund’s value equals or exceeds the Total Florida Cost Estimate, the Florida Phosphogypsum Trust Fund shall be invested only in U.S. Treasury Securities unless EPA in its unreviewable discretion agrees otherwise and the Parties modify this

describes the procedures performed and related findings, including whether or not differences or discrepancies were found in the comparison of specified financial information set out in the letter (including attachments and exhibits to the extent
specified in the letter) from the Guarantor’s CFO and the Guarantor’s Independently Audited, year-end financial statements for the last fiscal year, including all attachments. Where differences or discrepancies exist between
Guarantor’s CFO Letter and the Guarantor’s Independently Audited year-end financial statements, the report of procedures and findings shall reconcile any differences or discrepancies between the values or information represented in the

Defendant or as provided in notice by the Guarantor, provide alternate Financial Assurance in accordance with this Appendix (except for Paragraph 10.a(1)(c)), in an amount no less than the Florida Financial Assurance Delta. Defendant shall provide
such alternate Financial Assurance within thirty (30) Days of its determination or having received notice from the Guarantor. Defendant shall not seek dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree, and
shall not seek judicial review, regarding its determination or the Guarantor’s notice that the Guarantor is unable to meet the obligations of Recital 2 or that the Defendant is required to provide alternate Financial Assurance. In the event
that Defendant cannot provide alternate Financial Assurance within thirty (30) Days, Defendant may seek pursuant to Paragraph 27.c., above, a compliance plan and schedule. 

k.       Defendant shall, in the event EPA notifies Defendant that the Guarantor no longer meets its
obligations under Recital 2 of the Guarantee or pursuant to 40 C.F.R. §§ 264.143(f)(8) and 264.145(f)(8) is disallowed from continuing as a Guarantor because an independent CPA has issued in the report on examination of the
Guarantor’s audited financial statements an adverse opinion or a disclaimer of opinion, provide alternate Financial Assurance in an amount no less than the Florida Financial Assurance Delta. Defendant shall provide alternate Financial Assurance
within thirty (30) Days of EPA’s notice. In the event that Defendant cannot provide alternate Financial Assurance within thirty (30) Days, Defendant may request, pursuant to Paragraph 27.c., above, a compliance plan and schedule.
Dispute resolution and judicial review shall proceed pursuant to Section XI (Dispute Resolution), as modified below: 
 (1) In the event that
Defendant seeks judicial review of an EPA determination that the Guarantor no longer meets its obligations under Recital 2 of the Guarantee: 

(a) The standard of review shall be that set forth in Paragraph 70.a. of the Consent 

  
 40

Decree; and 
 (b) If the United States prevails, the Defendant or Guarantor shall
immediately provide alternate Financial Assurance in accordance with EPA’s Statement of Position or as directed by the Court in its resolution of the dispute. 

(2) In any dispute resolution, including judicial review, of EPA’s determination that the Guarantor can no longer continue as the
Guarantor based on an adverse opinion or disclaimer of opinion by the Guarantor’s independent CPA, the following conditions shall apply in addition to those set forth in Paragraph 32.k.(1)(a) and (b), above: 

(a) Defendant shall not contend that the adverse opinion or disclaimer of opinion was invalid or erroneous when issued, and
shall have the burden of demonstrating by clear and convincing evidence that the conditions giving rise to the adverse opinion or disclaimer of opinion no longer exist;

or stayed by the Court prior to that date; 
 (e) Defendant shall not subsequently seek a stay by the Court; and 

(f) If the Court has not acted upon Defendant’s petition by the date that Defendant’s (or Guarantor’s)

l.        Defendant shall establish within thirty (30) Days alternate Financial Assurance for the
Financial Assurance Delta if any of the following occurs: (1) the Guarantor does not provide a Representation and Certification as required; (2) the Guarantor provides notice that it is unable to provide the Representation and
Certification; (3) the Guarantor becomes aware of changes in the Guarantor’s financial condition that would invalidate or otherwise be inconsistent with the terms of the Representation and Certification; (4) the Guarantor becomes
aware of changes in the Total Cost Estimate that would invalidate or otherwise be inconsistent with the terms of the Representation and Certification; or (5) the Guarantor is unable to meet the conditions of the Guarantee. Such alternate
Financial Assurance shall be established in accordance with Section III.A. (Type A Financial Assurance), except for Paragraph 10.a(1)(c). In the event that Defendant 

  
 41

cannot provide alternate Financial Assurance within thirty (30) Days, Defendant may seek pursuant to Paragraph 27.c., above, a compliance plan and schedule. 

m.        Defendant shall, in the event that EPA determines and notifies the Defendant that the

alternate Financial Assurance within thirty (30) Days of EPA’s determination and notice. In the event that Defendant cannot provide alternate Financial Assurance within thirty (30) Days, Defendant may seek pursuant to Paragraph 27.c.,
above, a compliance plan and schedule. In the event that Defendant seeks judicial review of EPA’s determination under this Paragraph 32.m., and the United States prevails, the Defendant or Guarantor shall provide alternate Financial Assurance

EPA, in its sole unreviewable discretion, approves) be provided pursuant to Paragraph 10.a.(1)(c). 

o.          Defendant shall provide a Guarantee, in accordance with 40 C.F.R. §§
264.143(f)(10)(ii)-(iii) and 264.145(f)(11)(ii)-(iii), and modified as follows: (1) alternate Financial Assurance under the terms of the Guarantee shall be in accordance with Section III.A (Type A Financial Assurance) of Appendix 2; and

notifies EPA pursuant to Paragraph 15.e.(4), above, that Defendant (or Defendant’s Guarantor) no longer satisfies the corporate financial test criteria due to information that has come to its attention pursuant to Paragraph 15.e.(6)(c), above,
Defendant within ten (10) Days of such notice shall provide additional or alternate Financial Assurance as set forth below:

Mosaic Appendix 2 

Table of Contents

 a.        If Defendant fails to satisfy the corporate
financial test criteria and requirements of Paragraph 15.e., above, for each quarter in a given fiscal year (not including the fourth quarter (i.e., fiscal year-end)), except as provided in Paragraph 33.b., below, Defendant shall increase the
face value or the corpus of the Third-Party Mechanism by twenty-five percent (25%). If Defendant can satisfy the corporate financial test criteria by the fiscal year-end (i.e., in its annual submission pursuant to Paragraph 15.e.(3), above) and
Defendant’s quarterly review under Paragraph 15.e.(6)(b) for the following fiscal year does not result in notification from Defendant that it does not satisfy the corporate financial test, Defendant can request and EPA will authorize the
release of funds or a reduction in the value of the Third-Party Mechanism commensurate with the contemporaneous Cost Estimate and requirements of Paragraph 15.e. of this Appendix. 

b.        If Defendant fails to satisfy the corporate financial test criteria and requirements of
Paragraph 15.e., above, for any two (2) consecutive quarters in a given fiscal year (not including the fourth quarter (i.e., fiscal year-end)), Defendant shall provide alternate Financial Assurance in accordance with Paragraph 18 of this
Appendix. If Defendant can satisfy the corporate financial test criteria by the fiscal year-end (i.e., in its annual submission pursuant to Paragraph 15.e.(3)) and its annual submissions pursuant to Paragraph 15.e.(3), above, for the following two
(2) fiscal years do not trigger Paragraphs 15.e.(4) or 15.e.(5), above, EPA upon Defendant’s request will authorize a release of the funds or a reduction in the value of the Third-Party Mechanism(s) so that the value of the Third-Party
Mechanism is commensurate with the minimum threshold funding for a Third-Party Mechanism as specified in Attachment E plus an additional twenty-five percent (25%) of the Cost Estimate. 

c.        Defendant shall be deemed to be without Financial Assurance for purposes of enforcement (but
not for accessing or collecting Financial Assurance should it be necessary) if Defendant fails to meet a compliance schedule. Failure to timely comply with a compliance schedule or to provide alternate Financial Assurance pursuant to this Section
VIII.B (Compliance Schedule: Type B Financial Assurance) is not subject to the provisions of Section VII (Temporary Non-Compliance) of this Appendix. 
 IX.
Business Transactions 
 34.      No transfer of ownership or operation of a Facility shall relieve Defendant of its
Financial Assurance obligations under this Consent Decree, except as provided by this Section X (Force Majeure) and Section II (Applicability) of the Consent Decree. 

35.      At least thirty (30) Days prior to any transfer, Defendant shall submit to EPA information explaining the proposed
transfer in detail and stating whether Defendant requests the transfer of its Financial Assurance responsibilities to the Transferee pursuant to Section II (Applicability) of the Consent Decree and Paragraph 36.b, below. 

36.      In the event of a transfer of a Facility’s ownership or operation: 

a.        If Defendant is to retain its Financial Assurance obligations upon the transfer of the
Facility, Defendant, based on a Cost Estimate in Current Dollars, shall establish and fund a trust fund, or obtain a surety bond or letter of credit in accordance with this Appendix. Any existing trust fund established pursuant to Paragraph
10.a.(1)(c) shall remain in place. Defendant shall provide EPA the appropriate documentation evidencing the trust fund, surety bond, or letter of credit by the date of the Facility transfer. If using a trust fund, the portion of funds vested in

  
 43 

Mosaic Appendix 2 

Table of Contents

 
the trust fund that are not required to meet annual withdrawals shall be invested in U.S. Treasury Bills, or market-based notes and bills that achieve an investment goal or preservation of
principle and guarantee an inflation-adjusted rate of return no less than the 30-Year Treasury Constant Maturity Rate average for the previous twelve (12) months from the date of the annual Cost Estimate. If Defendant wishes to propose
alternate Financial Mechanism(s) in lieu of the trust fund, surety bond, or letter of credit, Defendant at least thirty (30) Days prior to the transfer shall submit an originally signed CFO Certification from the Defendant’s CFO, together
with supporting documentation, explaining the compelling reasons why the proposed alternate Financial Mechanism is being requested and is an equivalent substitute for the trust fund, surety bond, or letter of credit. Upon EPA’s approval, which
shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree but shall not be subject to judicial review, Defendant shall establish the approved Financial Assurance. If by the date of the transfer, EPA
does not approve such a request or the Defendant has not put in place the approved Financial Assurance, then Defendant shall fully fund the trust fund or obtain a surety bond or letter of credit, as described above. 

b.        If Transferee agrees to assume Defendant’s Financial Assurance obligations, Defendant
shall submit to EPA for approval an originally signed certification by Transferee’s CFO, together with supporting documentation, explaining in detail its ability to provide Financial Assurance pursuant to the requirements of this Appendix
(except for Paragraph 10.a.(1)(c)) and agreeing to provide the Financial Assurance if approved by EPA pursuant to Section II (Applicability) of the Consent Decree. Defendant shall comply with the requirements of Paragraph 36.a., above, until:
(1) EPA has approved Transferee’s proposed Financial Assurance; (2) the United States, after consultation with Florida, consents to the transfer of obligations pursuant to Section II (Applicability) of the Consent Decree;
(3) Transferee has established the approved Financial Assurance; and (4) EPA has given its consent for Defendant to terminate its Financial Assurance. If Defendant is providing Financial Assurance pursuant to Paragraph 10.a.(1)(c) of this
Appendix, and if the Transferee is acquiring all of the Defendant’s Operating and Closing Facilities in Florida, then the Florida Phosphogypsum Trust Fund (see Paragraph 30.b), and if still in existence, the required Guarantee
(see Paragraph 32.c) and the required letter of credit, will be the Financial Assurance subject to Paragraph 36.b.(4) that may be terminated. 

37.      If Defendant is providing Financial Assurance through the use of any Financial Mechanism other than the exclusive use
of a fully funded trust fund in Current Dollars, in the event of a business transaction that results, or Defendant determines will result, in an adverse material change to Defendant’s financial or corporate structure such that Defendant or its
successor (or a Guarantor of Defendant or its successor) has insufficient operating cash flow or Tangible Assets to cover the long-term (greater than one (1) year) financial liabilities as represented on the Defendant’s or successor’s
audited balance sheet and to comply with the Financial Assurance requirements of this Consent Decree, Defendant shall provide notice to EPA within fourteen (14) Days of identifying such adverse material change and comply with the requirements
for Financial Assurance in Paragraph 36.a., above. 
 38.      If Defendant becomes a private company, Defendant shall
provide, in addition to the CFO Letter in Attachment D (Forms 4), a full accounting of its financial condition and a certification from the CFO that the Defendant expects to have sufficient operating cash flow or Tangible Assets located in the
United States to cover long-term (greater than one (1) year) financial

liabilities as represented in the audited financial statements and to comply with the Financial Assurance requirements of this Consent Decree Defendant shall make such a certification as long as
Defendant provides a Self-Assurance Mechanism a part of its Financial Assurance. 
 X. Reservation of Rights 

39.      If EPA determines at any time that the Financial Assurance provided by Defendant no longer satisfies the requirements
of this Consent Decree, it shall notify Defendant. EPA may base this determination on Defendant’s failure to provide notices or documentation required by this Appendix as well as on a substantive evaluation of Defendant’s Financial
Assurance. Within thirty (30) Days of written notice from EPA that Defendant’s Financial Assurance no longer satisfies the requirements of this Consent Decree, Defendant shall submit to EPA for approval revised or alternate Financial
Assurance that satisfies the requirements of this Consent Decree. Defendant shall not cancel the existing Financial Assurance until the revised or alternate Financial Assurance has been approved by EPA and EPA has provided written consent permitting
Defendant to cancel the existing Financial Assurance. Failure to timely provide alternative Financial Assurance as required by this Section (or any Paragraph of this Appendix that references this Section) is not subject to the provisions of Section
VII of this Appendix. EPA’s determination shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of this Consent Decree, but not judicial review, and the time frames for notices and submissions under the dispute
resolution process shall be reduced by half (e.g., under Informal Dispute Resolution Defendant shall submit its Notice of Dispute within fifteen (15) Days). In the event that Defendant is providing Financial Assurance pursuant to Paragraph
10.a.(1)(c), and there is a conflict between this Paragraph 39 and Paragraph 32, then the provisions of Paragraph 32 shall control, except that the time frames for notices and submissions under Section XI (Dispute Resolution) of this Consent Decree
shall be reduced by half unless otherwise specified in Paragraph 32 of this Appendix.

 INSTRUCTIONS: 

1.            The Phosphogypsum Stack System Closure and Long Term Care Cost Estimate is to be adjusted
annually. Such adjustments may be made by either: (i) use of an inflationary factor (an “Inflation Adjustment”), or (ii) by recalculating the costs in Current Dollars reflecting cost adjustments (e.g., revised treatment
protocols, treatment costs, additional studies, material and labor cost) (a “Recalculated Adjustment”). See Paragraph 4.a., Appendix 2, Consent Decree. This form shall be used to provide the information regarding the adjustments to
the Cost Estimate and submitted annually as directed in Section II (Cost Estimate) of Appendix 2, of the Consent Decree, unless otherwise specified in Appendix 2 or the Consent Decree. 

2.            The annual update to the Cost Estimate shall be a Recalculated Adjustment performed pursuant to
Paragraph 4.c. Appendix 2 in 2017 and every five years thereafter. In other years, the update may be either an Inflation Adjustment or a Recalculated Adjustment performed pursuant to Paragraph 4.a. of Appendix 2. 

3.            This form shall also be used when required to provide an Updated Cost Estimate as set out in
Appendix 2. For example, this form shall be used for an Updated Cost Estimate that is to be provided at least sixty (60) days prior to constructing a lateral expansion at an Operating Facility (see Paragraph 4.c.(2)(i) of Appendix 2).

 4.            Fill in all sections, below, as appropriate. If using the inflationary factor, fill in
Section II.A, below. If recalculating the costs in Current Dollars, fill in Section II.B, below. 

5.            This form is to be sent to the appropriate individual(s) identified in Section XV (Notices) of
the Consent Decree.

Please check below the appropriate boxes identifying the type of Cost Estimate adjustment under this Section. In addition, Defendant shall complete Attachments B-1 and,
if needed, Attachments B-2 and B-3, unless providing Financial Assurance pursuant to Paragraph 10.a.(1)(c) of Appendix 2, in which case Defendant need not provide Attachments B-2 and B-3 and need only provide Attachment B-1 when providing the
Updated Cost Estimate pursuant 

  
 Mosaic 

Appendix 2, Attachment B

to Paragraph 4.c.(2). Requirements under the Consent Decree for Cost Estimate are found in Appendix 2, Section II, of the Consent Decree. 

 

	 ̈	A.             Inflation Adjustment to Cost Estimate 

The Cost Estimate may be adjusted for inflation by using an inflation factor. Please follow the instructions below in each subsection to derive the
inflation factor that must be used when adjusting the Cost Estimate for inflation. If providing Financial Assurance pursuant to Appendix 2, Subsection III.A, of the Consent Decree, complete subsections A(1)-(2), below. If providing Financial
Assurance pursuant to Appendix 2, Subsection III.B of the Consent Decree, complete subsections A(1) & (3), below. Use of an inflation factor may only occur when there is a Phosphogypsum Stack System Closure and Long Term Care Cost Estimate
and a periodic re-evaluation of the Cost Estimate is not required under Section II of Appendix 2 (e.g., Paragraph 4.c.). 
 Inflation Factor 

When adjusting for inflation to update the current dollar Cost Estimate in subsection A(1) and A(2), below, the inflation factor must be derived from the
most recent Implicit Price Deflator for Gross National Product (“Deflator”) published by the U.S. Department of Commerce in its Survey of Current Business. The inflation factor is the result of dividing the latest published
annual Deflator by the Deflator in effect at the time of the latest current dollar Cost Estimate. Attachment B, Exhibit 1 provides information (and examples) to use when deriving the imputed deflators for the annual inflationary adjustments under
Appendix 2. See also Appendix 2, Paragraphs 4.a.(1) and 4.a.(2), of the Consent Decree. (For additional information and guidance see 40 C.F.R. §§ 264.142(b)(1)&(2) and 264.144(b)(1)&(2).)

update the Long Term Care Cost Estimate for inflation, complete the following steps as instructed and place the information in the line items designated below: 
  

	 	(i)	To determine the Long Term Care and associated Water Management Costs in Current Dollars, calculate the costs as instructed in subsection A(2), above, filling in the necessary information. 

	 	(ii)	To inflate forward the current Long Term Care and associated Water Management costs for all remaining years of Long Term Care, adjust the costs as instructed in Attachment B-2, adjusting each year’s costs by the
inflation factor specified in Attachment B-2. (For additional reference information, see Paragraph 4.d., Appendix 2, of the Consent Decree.) 

	 	(iii)	Using each year’s adjusted costs due to inflation, place the information from Attachment B-2 in the corresponding line items located in Attachment B-3. 

	 	(iv)	 Following the instructions for Attachment B-3 to determine the present value of Long Term Care and associated Water Management costs for each year. To derive the
net present value dollars for inflation adjusted Long Term Care, add each year’s present value for Long Term Care costs; to

Q4 (imputed, if actual  

not yet published)
	 	 	 	 	 	 	 	 

 Instructions: See also Examples 1 and 2, below. 
  

	 	1.	The fiscal quarters for the prior year are listed in Column (A). The first entry in this column is Q1 of the prior year, and the last entry in this column is Q4 of the prior year. 

 

	 	2.	Add the published quarterly deflators into Column (B). Do not add any deflators to this column, if they have not yet been published. 

 

	 	3.	For each published deflator in Column (B), add the change from the previous quarter in column (C). For example, to calculate the change for Q2, subtract the published deflator value for Q1 from the published deflator
value in Q2. Column (C) should include entries only for quarters for which a published deflator is available. 

  

	 	4.	The value for Column (D) is calculated as the average of all entries in Column (C). Enter this value once, in the row with the latest published quarterly deflator. 

 

	 	5.	Add the value in Column (D) to the latest published quarterly deflator to calculate the following imputed quarterly deflator in Column (E). (The entries in this column will correspond to the quarters for which
there are no published quarterly deflators.) To impute quarterly deflators for more than one quarter, continue adding the value in Column (D) to each imputed quarterly deflator to calculate the quarterly deflator for the next year.

 This example assumes that the latest published quarterly deflator is Q3 2013. The imputed quarterly deflator for Q4 2013 is found in
Cell 4E, 107.764.

	4  	 	Q4 2013	 	 	 	 	 	 	 	107.176

 This example assumes that the latest published quarterly deflator is Q2 2013. Because there are only two quarters with published
deflators in Column (B), the values in Column (C) and Column (D) are the same. The value in Cell D2 is added to Cell B2 to derive the imputed deflator for Q3 2013 (see Cell E3). To derive the imputed deflator for Q4 2013, the value in Cell
D2, is added to imputed deflator for Q3 2013 (Cell E3) to derive the imputed deflator for Q4 2013 (Cell E4).

 Attachment B-1: Instructions 

Attachment B-1 (and associated Forms 1-3) provides a framework that summarizes the types of activity, quantity (or volume), and costs
associated Phosphogypsum Stack System Closure (Form 1), Long Term Care (Form 2) and the associated Water Management activities (Form 3). The information to be captured in the Exhibits and submitted in accordance with Section II (Cost Estimate),
Appendix 2 of the Consent Decree, is Facility specific and, therefore, as appropriate, the line item information in the Exhibits shall be adjusted accordingly, as well as any other information or assumptions provided in (or accompanying) the
Exhibits. 
 In general, the costs for the associated Water Management activities are broken out based on which activities are associated
with Phosphogypsum Stack System Closure and which activities are associated with Long Term Care. In additions to listing out the activity, and costs, any assumptions, comments descriptions or relevant information (e.g., adjusted for inflation)
needed to explain the costs shall be included. For example, specifying the estimated hours per week for an activity; yearly salary for an on-site engineer tasked with Long Term Care activities; assumptions for mowing the grassed stacks; assumptions
for the identified contingency; and what costs are captured by administrative costs.

 ADJUSTING LONG TERM CARE AND ASSOCIATED WATER MANAGEMENT COSTS TO CALCULATE CURRENT (THEN-YEAR) COSTS 

Instructions: 
  

	 	1.	Use the information and formulas, below, to determine the current (then-year) dollars for Long Term Care and associated Water Management costs (i.e., columns [C] and [E], below). 

	 	2.	The Long Term Care and associated Water Management costs in Current Dollars to be used in columns [B] and [D], below, shall be obtained, as appropriate, by calculating the inflation adjusted Long Term Care and
associated Water Management costs pursuant to Section II.A(2) of Attachment B or from the information provided in Section II.B(1)(b) of Attachment B. 

	 	3.	For purposes of determining the inflation factor, the Gross Domestic Product (GDP) Deflator is as specified in the “GDP (Chained) Price Index” of the Gross Domestic Product Deflators Used in the Historic
Tables, published by the Office of Management and Budget (“OMB”). The inflation factor used to inflate the costs in this attachment shall be derived from the mathematical average of the calculated inflation factors for each year over a
five-year period. Each year’s calculated inflation factor shall be the product of dividing the GDP for the relevant year by the GDP for the year immediately prior, beginning with the first year in which the GDP Deflator is an estimate and for
each year thereafter until the fifth year. (See Paragraph 4.d, Appendix 2, of the Consent Decree.) 

	 	4.	The inflated costs, as calculated in this Attachment B-2, shall be used to calculate the present value for Long Term Care and associated Water Management costs in Attachment B-3 and to provide information in Section
II.A(3) and Section II.B(2) of Attachment B. [Note: Each year’s adjusted costs due to inflation as specified in columns [C] and [E], below, shall be placed in the corresponding line items designated by year in columns [B] and [D] in Attachment
B-3.]

 PRESENT VALUE OF LONG TERM CARE AND ASSOCIATED WATER MANAGEMENT 

Instructions: 
  

	 	1.	Use the information and formulas, below, to calculate the present value of Long Term Care and associated Water Management costs. [Note: Present value is to be calculated only when providing Financial Assurance under
Section III.B, Appendix 2, of the Consent Decree.] 

	 	2.	In columns [B] and [D], insert the inflation-adjusted annual costs beginning in the year when Long Term Care is expected to begin. These costs have been generated in Attachment B-2, representing inflation adjusted
(then-year) dollars in the year that the cost are expected to be incurred. [Note: The values in columns [B] and [D], below, are the same as those represented in columns [C] and [E] from Attachment B-2.] 

	 	3.	Following the formula listed below, calculate the present value of the Long Term Care and associated Water Management costs in each year. 

	 	4.	The present value, as calculated in this Attachment B-3, shall be used, as instructed, to fill in Sections II.A(3) and II.B(2) of Attachment B.

As part of the annual update of the Phosphogypsum Stack System Closure and Long Term Care Cost Estimate, Defendant shall submit Attachment C. The costs
represented in Attachment C are in Current Dollars for the year in which the annual submittal is required. When filling out Attachment C, use the information and definition specified below, and provide any assumptions utilized to provide the
information. If it is determined that additional columns are required to accurately represent the annual volume of water to be addressed during Phosphogypsum Stack System Closure or Long Term Care, insert such information providing appropriate notes
and assumptions for the additional information. 
  

	 	1.	Ponded Water Inventory is the annual volume of water to be removed from the cooling pond, the sedimentation ponds on the Phosphogypsum Stack, the return canal and collection ditches, and from other storage or surge
ponds, or sumps in excess of  1⁄4 acre, that are part of the Phosphogypsum Stack System (such water is also known as “process water inventory”).

	 	2.	Water Balance During Closure is the average annual rainfall that is captured in the Phosphogypsum Stack System minus the average annual evaporation from the ponded water surfaces and evapotranspiration from non-ponded
surfaces. 

	 	3.	Drainable Pore Water is the annual volume of water contained within the pores of the phosphogypsum that gravity drains during and after closure of the Phosphogypsum Stack. 

	 	4.	Infiltration is the annual volume of water that infiltrates into the side slopes of the closed Phosphogypsum Stack.1 

	 	5.	Total Annual Water Volume is the summation of Ponded Water Inventory, Water Balance During Closure, Drainable Pore Water, and Infiltration water. 

	 	6.	Annual Average Removal Rate, in gallons per minute (GPM), is determined by dividing the Total Annual Water Volume by 525,600 minutes per year. 

	 	7.	Annual Water Removal Cost is the total annual cost in millions of dollars needed for the Total Annual Water Volume to achieve the applicable standards. 

	 	8.	Planning & Closure Period O&M and Monitoring Costs represent annual program management costs, miscellaneous O&M expenses, surface water monitoring costs, groundwater monitoring costs and piezometer
installation costs incurred during the five year closure construction period and one year planning period. 

	 	9.	Closure Construction Costs represent the annual cost of all materials, labor and equipment to close the phosphogypsum stack system including but not 

 

1 The area of the side slopes of the Phosphogypsum Stack is the horizontal projection of the grassed
slopes. The lined ditches and roads are not included in the slope area.

sumps/pump stations; header pipes; grassing soil and phosphogypsum surfaces; security fence; surface water control; permitting and design services; and construction management, QA/QC, and surveying. 

	 	10.	Program Management Costs represent the annual costs to manage the facility during the 50-year long-term care period. 

	 	11.	Long Term Care Operational Costs are based on annual: (a) costs for on-site personnel to conduct maintenance, inspection and care activities during the Long Term Care period with a 5% contingency allowance;
(b) surface water and groundwater monitoring and analysis costs; (c), mowing and land surface care costs; (d) contingency repairs (e.g., restoration of eroded areas); and (e) pump operation and maintenance costs (e.g., convey water
from seepage collection system to water treatment). 

	 	12.	Total Water Treatment and Closure Costs represent the sum of the Annual Water Treatment Costs, Planning & Closure Period O&M and Monitoring Costs, Closure Construction Costs, Long Term Care Period Program
Management Costs, and Long Term Care Operational Costs.

(b) To purchase shares in any investment company registered under the Investment Company Act of 1940, 15 U.S.C. 80a-1 et seq., including one which may be

Agreement or by law, the Trustee is expressly authorized and empowered: 
 (a) To sell, exchange, convey, transfer, or otherwise dispose of any property
held by it, by public or private sale. No person dealing with the Trustee shall be bound to see to the application of the purchase money or to inquire into the validity or expediency of any such sale or other disposition; 

(b) To make, execute, acknowledge, and deliver any and all documents of transfer and conveyance and any and all other instruments that may be necessary or
appropriate to carry out the powers herein granted;

Trustee with respect to matters disclosed in the statement. 
 Section 11. Advice of Counsel. The Trustee may from time to time consult with counsel,
who may be counsel to the Grantor, with respect to any question arising as to the construction of this Agreement or any action to be taken hereunder. The Trustee shall be fully protected, to the extent permitted by law, in acting upon the advice of

Successor Trustee’s acceptance of the appointment, the Trustee shall assign, transfer, and pay over to the successor trustee the funds and properties then constituting the Fund. If for any reason the Grantor cannot or does not act in the event

trust in a writing sent to the Grantor, the EPA Regional Administrator, and the [State Agency Head], and the present Trustee by certified mail ten (10) days before such change becomes effective. Any expenses incurred by the Trustee as a

		 		 		 	      ●  	  	10-year yield 2.00-2.74% = 80% 5-yr, 20%
		 		 		 		  	10-yr
		 		 		 	      ●  	  	10-year yield 2.75-3.49% = 60% 5-yr, 40%

Protection Agency (“EPA”) and [insert appropriate State designation]. 
 Whereas, pursuant to the Resource Conservation and
Recovery Act (“RCRA”), as amended, 42 U.S.C. §§ 6901 et seq., Mosaic Fertilizer has entered into a Consent Decree with EPA and [insert appropriate State designation] (dated [insert date], Docket No. [insert case

 Whereas, the Effective Date of the Consent Decree is defined in Section XVI (Effective
Date) of the Consent Decree; 
 Whereas, the Consent Decree requires Mosaic Fertilizer to provide Financial Assurance to EPA and [insert
appropriate State designation] to address Phosphogypsum Stack System Closure and Long Term Care, whenever required to do so, at the Operating and/or Closing Facilities; 

Whereas, in order to provide a portion of the Financial Assurance required by the Consent Decree, Mosaic Fertilizer has agreed to provide EPA
and [insert appropriate State designation] with a Guarantee, issued by the Guarantor, as set forth more fully in this Guarantee, below. 
 I.
Recitals 
 Now therefore, in consideration of the promises contained herein and for the other good and valuable consideration, the receipt and adequacy of
which is hereby acknowledged, the Guarantor agrees to the following:

identified in the Consent Decree covered by this Guarantee: [List for each facility: EPA Identification Number,

name, address and Cost Estimate for each Facility]. 
 2. For value received from Mosaic
Fertilizer, Guarantor guarantees to EPA and [insert appropriate State designation] that, in the event Mosaic Fertilizer fails to perform Phosphogypsum Stack Closure and/or Long Term Care at any or all of the Operating and/or Closing
Facilities in accordance with the Initial Phosphogypsum Stack System Closure Plan or Permanent Phosphogypsum Stack System Closure Plan and other terms of the Consent Decree, whenever required to do so, the Guarantor shall do so, or shall establish
alternate Financial Assurance in the name of Mosaic Fertilizer in accordance within Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), of the Consent Decree, in an amount at least equal to the Total [insert State name] Cost
Estimate less the sum of: (i) the most recent value of the [insert State name] Phosphogypsum Trust Fund established in accordance with Appendix 2 of the Consent Decree and as represented by the Trustee in its most recent valuation
statement to Grantor and (ii) the aggregate value of any other Third-Party Mechanism secured to establish Financial Assurance in accordance with Appendix 2 of the Consent Decree (“[insert State name] Financial Assurance
Delta”). 
 3. Guarantor shall comply with the reporting requirements of Paragraph 32.h. of Appendix 2 of the Consent Decree, including an annual
Representation and Certification from the Chief Financial Officer of Guarantor stating that Guarantor has the financial resources for the next fiscal year to fund the lesser of: (i) $415 million or (ii) the Financial Assurance Delta. 

4. In the event that Guarantor determines, at any time for the duration of the Guarantee, for any reason, that: (i) the Guarantor is unable to meet the
terms of the Guarantee, including Recital 2; (ii) the Guarantor is unable to provide the Representation and Certification required under Recital 3 of this Guarantee; (iii) the Guarantor becomes aware of any changes in the Total Cost
Estimate or the Guarantor’s financial conditions that would invalidate or otherwise be inconsistent with the Representation and Certification; or (iv) the Guarantor becomes aware of any changes in the Total Cost Estimate that would
invalidate or otherwise be inconsistent with the Representation and Certification, then Guarantor shall, within five (5) Days of such a determination, provide notice of such determination by certified mail to Mosaic Fertilizer, EPA and

perform Phosphogypsum Stack System Closure and/or Long Term Care at the Operating and Closing Facilities or establish alternate Financial Assurance in accordance with Appendix 2 in an amount that is at least equal to the Financial Assurance Delta.
The Guarantor may rebut this presumption only by clear and convincing evidence.

 6. Guarantor agrees that, within thirty (30) Days after providing the notice required by Recitals 4 and 5,

a Guarantor as specified in Paragraph 32.k. of Appendix 2 because the independent Certified Public Accountant has issued in the report on examination of the Guarantor’s audited financial statements an adverse opinion or a disclaimer of opinion,
or has failed to provide a Representation and Certification as required pursuant to Recital 3 or provided an invalid Representation and Certification, and if Mosaic Fertilizer during that time has not provided alternate Financial Assurance for the

(except for Paragraph 10.a(1)(c)), in the name of Mosaic Fertilizer, in an amount at least equal to the [insert State name] Financial Assurance Delta. In the event that Mosaic Fertilizer invokes dispute resolution, subject to the terms set
forth in Appendix 2, of a determination by EPA or [insert appropriate State designation], Guarantor agrees that it shall be bound by the final outcome of the dispute resolution.

under Paragraphs 32.j. and 32.l. of Appendix 2 of the Consent Decree to establish alternate Financial Assurance in accordance with Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), or to return Mosaic Fertilizer to compliance if EPA
approves a compliance plan and schedule pursuant to Section VII (Temporary Non-Compliance) of Appendix 2 of the Consent Decree. Acceptance by EPA and [insert appropriate State designation] of any compliance plan and schedule shall not relieve
The Mosaic Company of its obligations under this Corporate Guarantee. 
 8. In the event that EPA approves a compliance plan and schedule pursuant to

The planned changes or expansions include dates when construction is currently estimated to begin. These dates are subject to change based on numerous factors,
including years for attaining intermediate stack elevations and reaching terminal stack elevations, changes in market conditions, changes in production rates and Mosaic’s business plans, and changes to Mosaic’s long-term operating plans
for the Facilities. In any event, activation of the planned changes or expansions will likely occur approximately 2 years after the beginning of construction. 
The
planned changes or expansions also include Mosaic’s best estimate of the locations, area, and acreage for each planned change or expansion. These estimates are based on Mosaic’s projected long-term operating plans and projected
availability of rock sources for each Facility. The acreages for planned expansions are based upon either: (1) the lined area and area of surrounding perimeter containment dikes for lateral expansions beyond the existing phosphogypsum stack system
footprint; or (2) lined areas atop existing stack surfaces for lateral expansions contained within the existing phosphogypsum stack system.

The planned changes or expansions include dates when construction is currently estimated to begin. These dates are subject to change based on numerous factors, including years for
attaining intermediate stack elevations and reaching terminal stack elevations, changes in market conditions, changes in production rates and Mosaic’s business plans, and changes to Mosaic’s long-term operating plans for the Facilities. In
any event, activation of the planned changes or expansions will likely occur approximately 2 years after the beginning of construction. The planned changes or expansions also include Mosaic’s best estimate of the locations, area, and acreage
for each planned change or expansion. These estimates are based on Mosaic’s projected long-term operating plans and projected availability of rock sources for each Facility. The acreages for planned expansions are based upon either: (1) the
lined area and area of surrounding perimeter containment dikes for lateral expansions beyond the existing phosphogypsum stack system footprint; or (2) lined areas atop existing stack surfaces for lateral expansions contained within the existing
phosphogypsum stack system. FIGURE 8 NORTH-SOUTH CROSS * [**] BARTOW FACILITY

Instructions: The Corporate Guarantee for Phosphogypsum Stack System Closure and Long Term Care, as specified in Appendix 2 of the Consent Decree, must be
worded as follows, except that instructions in brackets are to be replaced with the relevant information, if applicable, and the brackets deleted. 

Corporate Guarantee for Phosphogypsum Stack System Closure and Long Term Care 

Guarantee made this September 28, 2015 by The Mosaic Company, a business corporation organized under the laws of the State of Delaware,
herein referred to as “Guarantor.” This Guarantee is made on behalf of Mosaic Fertilizer, LLC (“Mosaic Fertilizer”) of 3033 Campus Dr., Plymouth, Minnesota 55441, which is our wholly-owned subsidiary, to the United States

 Whereas,
pursuant to the Resource Conservation and Recovery Act (“RCRA”), as amended, 42 U.S.C. §§ 6901 et seq., Mosaic Fertilizer has entered into a Consent Decree with EPA and FDEP (dated [insert date], Docket No. [insert case

Whereas, the Effective Date of the Consent Decree is defined in Section XVI (Effective Date) of the Consent Decree; 

Whereas, the Consent Decree requires Mosaic Fertilizer to provide Financial Assurance to EPA and FDEP to address Phosphogypsum Stack System

 Now therefore, in consideration of the promises

2. For value received from Mosaic Fertilizer, Guarantor guarantees to EPA and FDEP that, in the event Mosaic Fertilizer fails to perform Phosphogypsum Stack
Closure and/or Long Term Care at any or all of the Operating and/or Closing Facilities in accordance with the Initial Phosphogypsum Stack System Closure Plan or Permanent Phosphogypsum Stack System Closure Plan and other terms of the Consent Decree,
whenever required to do so, the Guarantor shall do so, or shall establish alternate Financial Assurance in the name of Mosaic Fertilizer in accordance within Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), of the Consent Decree, in
an amount at least equal to the Total Florida Cost Estimate less the sum of: (i) the most recent value of the Florida Phosphogypsum Trust Fund established in accordance with Appendix 2 of the Consent Decree and as represented by the Trustee in
its most recent valuation statement to Grantor and (ii) the aggregate value of any other Third-Party Mechanism secured to establish Financial Assurance in accordance with Appendix 2 of the Consent Decree (“Florida Financial Assurance
Delta”). 
 3. Guarantor shall comply with the reporting requirements of Paragraph 32.h. of Appendix 2 of the Consent Decree, including an annual
Representation and Certification from the Chief Financial Officer of Guarantor stating that Guarantor has the financial resources for the next 

  
 Mosaic 

Appendix 2, Attachment I 

Table of Contents

 
fiscal year to fund the lesser of: (i) $415 million or (ii) the Financial Assurance Delta. 

4. In the event that Guarantor determines, at any time for the duration of the Guarantee, for any reason, that: (i) the Guarantor is unable to meet the
terms of the Guarantee, including Recital 2; (ii) the Guarantor is unable to provide the Representation and Certification required under Recital 3 of this Guarantee; (iii) the Guarantor becomes aware of any changes in the Total Cost
Estimate or the Guarantor’s financial conditions that would invalidate or otherwise be inconsistent with the Representation and Certification; or (iv) the Guarantor becomes aware of any changes in the Total Cost Estimate that would
invalidate or otherwise be inconsistent with the Representation and Certification, then Guarantor shall, within five (5) Days of such a determination, provide notice of such determination by certified mail to Mosaic Fertilizer, EPA and FDEP.
Such notice shall be admissible in evidence in any litigation and create a presumption that the Guarantor cannot provide the required Representation and Certification, and that the Guarantor cannot perform Phosphogypsum Stack System Closure and/or
Long Term Care at the Operating and Closing Facilities or establish alternate Financial Assurance in accordance with Appendix 2 in an amount that is at least equal to the Financial Assurance Delta. The Guarantor may rebut this presumption only by
clear and convincing evidence. 
 5. Any notice provided by Guarantor of Guarantor’s inability to comply with the requirements of this Guarantee, shall
include a statement of the value of the guaranteed obligations based on current Updated Cost Estimates, and the amount of financial resources that the Guarantor expects to have available for the next fiscal year either to perform Phosphogypsum Stack
System Closure and/or Long Term Care activities at the Operating and Closing Facilities or to provide alternate Financial Assurance. 
 6. Guarantor agrees
that, within thirty (30) Days after providing the notice required by Recitals 4 and 5, or after being notified by Mosaic Fertilizer, EPA, or FDEP of a determination that the Guarantor no longer is able to meet its obligations under Recital 2 of
this Guarantee or is disallowed from continuing as a Guarantor as specified in Paragraph 32.k. of Appendix 2 because the independent Certified Public Accountant has issued in the report on examination of the Guarantor’s audited financial
statements an adverse opinion or a disclaimer of opinion, or has failed to provide a Representation and Certification as required pursuant to Recital 3 or provided an invalid Representation and Certification, and if Mosaic Fertilizer during that
time has not provided alternate Financial Assurance for the Florida Financial Assurance Delta (including written approval by EPA and FDEP), then Guarantor shall provide alternate Financial Assurance in accordance with Section III.A of Appendix 2
(except for Paragraph 10.a.(1)(c)), in the name of Mosaic Fertilizer, in an amount at least equal to the Florida Financial Assurance Delta. In the event that Mosaic Fertilizer invokes dispute resolution, subject to the terms set forth in Appendix 2,
of a determination by EPA or FDEP, Guarantor agrees that it shall be bound by the final outcome of the dispute resolution. 
 7. In the event that Guarantor
provides notice under Recital 4, Guarantor shall make financial resources available to Mosaic Fertilizer to meet its obligation under Paragraphs 32.j. and 32.1. of Appendix 2 of the Consent Decree to establish alternate Financial Assurance in
accordance with Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), or to return Mosaic Fertilizer to compliance if EPA approves a compliance plan and schedule pursuant to Section VII (Temporary Non-Compliance) of Appendix 2 of the
Consent Decree. Acceptance by EPA and 

  
 Mosaic 

Appendix 2, Attachment I 

Table of Contents

 
FDEP of any compliance plan and schedule shall not relieve The Mosaic Company of its obligations under this Corporate Guarantee. 

8. In the event that EPA approves a compliance plan and schedule pursuant to Section VII (Temporary Non-Compliance) of Appendix 2 to return Mosaic Fertilizer
to compliance with its Financial Assurance obligations under the Consent Decree, and such plan requires the Guarantor to undertake certain activities or provide financial resources, in addition to that specified in Recital 7 above, then Guarantor
shall carry out those activities in a timely manner in accordance with the approved compliance plan and schedule. 
 9. The Guarantor shall notify Mosaic
Fertilizer, EPA, and FDEP by e-mail as well as by certified mail, of a voluntary or involuntary proceeding under Title 11 (Bankruptcy), U.S. Code, naming Guarantor as debtor, within twenty-four (24) hours after commencement of the proceeding.

 10. Guarantor shall remain bound under this Guarantee notwithstanding any or all of the following: amendment or modification of the Phosphogypsum Stack
System Closure Plan or Permanent Phosphogypsum Stack System Closure Plan, as applicable, amendment or modification of the Consent Decree, the extension or reduction of the time of performance of Phosphogypsum Stack System Closure or Long Term Care,
or any other modification or alteration of an obligation of Mosaic Fertilizer pursuant to the Consent Decree. 
 11. Guarantor shall remain bound under this
Guarantee for as long as Mosaic Fertilizer must comply with the applicable Financial Assurance requirements of the Consent Decree (including appendices and attachments of the Consent Decree) for the Operating and Closing Facilities, except as
provided in Recital 12 of this Guarantee. 
 12. Guarantor may terminate this Guarantee by sending notice of cancellation by certified mail to Mosaic
Fertilizer, EPA, and FDEP, provided that Mosaic Fertilizer or the Guarantor obtains, and EPA and FDEP approves, alternate Financial Assurance in accordance with Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), of the Consent Decree,
in an amount at least equal to the Florida Financial Assurance Delta. In the event that Mosaic Fertilizer fails to provide alternate Financial Assurance or obtain EPA’s and FDEP written approval of the alternate Financial Assurance, Guarantor
agrees and shall provide alternate Financial Assurance in the name of Mosaic Fertilizer. This Guarantee shall not terminate unless and until EPA and FDEP has approved the alternate Financial Assurance in writing and such approved alternate Financial
Assurance is in place. 
 13. Guarantor expressly waives notice of acceptance of this Guarantee by EPA, FDEP, or by Mosaic Fertilizer. Guarantor also
expressly waives notice of amendments or modifications of the Phosphogypsum Stack System Closure Plan and/or Permanent Phosphogypsum Stack System Closure Plan and of amendments or modifications of the Consent Decree. 

14. Guarantor shall, when required to provide information regarding obligations under federal and state law that are assured through the use of a financial
test or a guarantee, include the obligations under this Guarantee.

	 	D.	Wastes generated from Downstream Operations only. 

 Prior to commencement of the GHT
or BHT, the wastes from these units may continue to be managed consistent with Mosaic’s consolidated waste management practices submittal dated September 8, 2015. Following the commencement of the operation of the GHT and BHT, if the
Downstream wastes are not sent to the GHT or BHT for recovery and reuse, Mosaic shall make a hazardous waste determination of such wastes and manage them in accordance with RCRA. Following the commencement of the operation of the GHT and BHT,
downstream scrubber effluent shall not be discharged to the Phosphogypsum Stack System. 
 II. Background3 
 Mosaic Bartow’s primary commercial products are the solid ammoniated phosphate
fertilizers: monoammonium phosphate (MAP), diammonium phosphate (DAP), and MicroEssentials® (MES), as well as fluorosilicic acid (FSA). DAP is manufactured in two production trains designated
as #3 DAP/MAP and #4 DAP. MAP and MicroEssentials® are produced in #3 DAP/MAP. Ammonia and phosphoric acid are the primary reactants for MAP, DAP, and MicroEssentials® and are consumed in the production of ammoniated fertilizers on-site. 
 Phosphoric acid is produced
by the digestion of phosphate rock with sulfuric acid. Mosaic Bartow manufactures phosphoric acid in one production plant with two distinct reactors on-site. The reaction yields phosphoric acid and phosphogypsum (gypsum). Gypsum is filtered from the
phosphoric acid on rotating pan filters, slurried with Process Wastewater in gypsum slurry tanks, and the resultant slurry is pumped to a lined Phosphogypsum Stack (gypstack). Because the production of phosphoric acid is a water-intensive process
and water is used throughout the process (e.g., as acid dilution water, in the ball mills, evaporators, condensers and as a pipe and tank cleaning agent), approximately 1.6 billion gallons of Process 

Wastewater is constantly stored in, and circulating throughout, the facility’s Phosphogypsum Stack System. Mosaic Bartow deposits slurried gypsum in a
60-mil high density polyethylene (HDPE) lined Phosphogypsum Stack located southeast of the facility, south of US Hwy 60. The lined Phosphogypsum Stack operates in conjunction with the existing Phosphogypsum Stack System. 

Mosaic Bartow’s Phosphogypsum Stack System is partially lined with 100-mil or 80-mil HDPE. Mosaic Bartow operates the Phosphogypsum Stack System under
an Industrial Wastewater Facility Permit issued by the Florida Department of Environmental Protection (FDEP).

 III. First Saleable Products at Mosaic Bartow 

The line marking the division between Upstream and Downstream Operations lies at the point of generation of the First Saleable Product. Mosaic Bartow
generates three first saleable products used as direct feedstocks to MAP, MicroEssentials® or DAP production: 
  

	 	1)	30% phosphoric acid that is routed to MAP/DAP rather than to further concentration steps 

	 	2)	54% clarified phosphoric acid (greater than 1% solids) 

	 	3)	54% unclarified phosphoric acid (sludge) 

 Downstream Operations at Mosaic Bartow are associated with the
storage, transport or use of these First Saleable Products in MAP/DAP and MicroEssentials® operations. Intermediary between the production of 30% acid and the production of 54% clarified acid,
Mosaic Bartow recovers fluoride vapors to produce Fluorosilicic Acid (FSA) as a First Saleable Product. 
 IV.
Phosphoric Acid and FSA Production – Phosphoric Acid Plant 
 Figure 13 identifies Upstream Operations, BHT Recovery Units, Mixed-Use
Units, and Grandfathered Units within Mosaic Bartow’s Phosphoric Acid Plant. 
 Mosaic Bartow’s Phosphoric Acid Plant has approximately 95%
impervious surfaces and approximately 20% of the Plant has 40-mil HDPE liner installed below the concrete. Below-grade concrete trenches and pipelines throughout the Plant convey Process Wastewater from the Plant to the Phosphogypsum Stack System at
a flow rate of approximately 50,000 – 60,000 GPM. The main Process Wastewater return ditches within the plant are composed of high performance concrete. 

A. Standard Acid Flow Configuration 

The Phosphoric Acid Plant produces three concentrations of phosphoric acid for use in fertilizer manufacturing: 30% P2O5, 40% P2O5, and 54% P2O54,5. The 30% acid that is not used directly as feedstock to fertilizer manufacturing
is further processed to 54% P2O5 in Upstream Operations. The standard phosphoric acid manufacturing process described below is illustrated in process flow diagram (Figure 2). Deviations from the standard acid flow configuration are necessary on
periodic short-term intervals. 
 Mosaic Bartow produces phosphoric acid in two reactors designated as the Phosphoric acid Reactor V-Train (“Attack
Tank V-Train”) and the Phosphoric acid Reactor U-Train (“Attack 
  

 

4 Note that although the terms P2O5 and phosphoric acid (H3PO4) are used interchangeably, the
concentrations are not interchangeable. Mosaic manufactures phosphoric acid, however, in this document we refer to the concentration of the acid in terms of P2O5 concentration, rather than phosphoric acid concentration. P2O5 concentration can be
converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to an approximate concentration of P2O5 by multiplying by 0.7242. 

5 All phosphoric acid concentrations are approximate and fluctuate slightly.

	2)	Acid Transfer between the Phosphoric Acid Plant and #3 DAP/MAP (BHT Recovery Units) 

Mosaic Bartow has two primary transfer lines that serve to transport 30% phosphoric acid between the Phosphoric Acid Plant and #3 DAP/MAP.
The “DAP1” and “DAP2” transfer lines transport 30% acid from either the 33A Tank (C3T33A) or 33B Tank (C3T33B) to the 34A Tank (D3T34A) or 54B Tank (D3T54B). 

Mosaic Bartow has two primary transfer lines that serve to transport 54% phosphoric acid between the Phosphoric Acid Plant and #3 DAP/MAP:

	 	1.	The “53C” Transfer Line transports sludge (underflow) from the 54% clarifier (C5T52) or clarified 54% acid from the 53 Tank ((C5T53) to either the 54A Tank (D3T54A) or 54B Tank (D3T54B). 

	 	2.	The “53B” Transfer Line transports clarified 54% acid from the 53 Tank (C5T53) to either the 54A Tank (D3T54A) or 54B Tank (D3T54B). 

The locations of the transfer lines are illustrated in Figure 6. The estimated line lengths and cleaning frequencies are listed in Table 4.

  

	3)	Acid Transfer between the Phosphoric Acid Plant and #4 DAP (BHT Recovery Units) 

Mosaic Bartow has two primary transfer lines that serve to transport 30% phosphoric acid between the Phosphoric Acid Plant and #4 DAP. The
“DAP1” and “DAP2” transfer lines transport 30% acid from either the 33A Tank (C3T33A) or 33B Tank (C3T33B) to either the 35A Tank (D4T35A) or 35B Tank (D4T35B). 

Mosaic Bartow has two primary transfer lines that serve to transport 54% phosphoric acid between the Phosphoric Acid Plant and #4 DAP. The

The locations of the transfer lines are illustrated in Figure 7. The estimated line lengths and cleaning frequencies are listed in Table 5.

 D. Fluorosilicic Acid (FSA) Standard Process Configuration 

Mosaic Bartow recovers fluoride vapors from Second Stage Evaporator # 5. The recovery of fluoride vapors produces FSA. A generic depiction of the FSA
production process is illustrated in Diagram 1. 
 The Second Stage Evaporator #5 has a FSA production unit, also called a “Swift Tower,”
integrated with a barometric condenser. The Swift Tower receives gas emitted from the concentration of 43% P2O5 to 54% P2O5 through evaporation. The gas is condensed in the Swift Tower and the liquid is continuously recirculated through a seal tank
and back through the Swift Tower to maintain the seal and operation of the FSA Swift Tower. 

  
 17 

Table of Contents

 Mosaic Bartow 

Facility Report 
  

 FSA is not always produced. When FSA is not being produced for sale or for use as a cleaning solution, the
gases pass through the Swift Tower to the barometric condenser, there is no recirculation of FSA through the Swift Tower, and therefore FSA is not produced. Even when FSA is not being produced, the FSA Seal Tank remains an essential part of the
Phosphoric Acid Evaporator by sealing the Swift Tower downleg. 
 When FSA is being produced for sale or for use as a cleaning solution, recirculated
liquid will continue to absorb fluoride vapors until the desired strength of FSA is obtained. FSA for sale is a solution of approximately 23-26% strength and specific gravity of 1.20 -1.23. 

Once the FSA reaches the desired strength for sale, a slip stream from the recirculation line between the FSA Seal Tank and FSA Swift Tower is sent to the
FSA Day Tank (C4T81). In the FSA Day Tank (C4T81), the solution is isolated and tested for meeting customer specifications. Solutions meeting customer specifications in the FSA Day Tank (C4T81) are transferred to the FSA Storage Tank (C4T80) and
sold to customers off-site. 
 If the solution does not meet the minimum customer specifications, within 90 days of that determination, the contents from
the FSA Day Tank (C4T81) must be: 

	 	1.	Returned to the 42 Tank (C4T42) for reprocessing and recovery of acid value when FSA is being produced for sale and/or internal consumption; or 

	 	2.	Returned to the 40% Clarifier Feed Tank (C4T40) for reprocessing and recovery of acid value when FSA is being produced for sale and/or internal consumption; or 

	 	3.	Sent to the Phosphoric acid reactors for reprocessing and recovery of acid values, or; 

	 	4.	Discharged to the Phosphogypsum Stack System, if in compliance with the land disposal restriction (LDR) standards set forth in 40 C.F.R. Part 268, Subpart D, or; 

	 	5.	Following commencement of operation of the BHT: 

	 	a.	Sent to the Big Holding Tank, as described in Section VI (Compliance Projects) of this Report, for reprocessing and recovery of acid values; or 

	 	b.	Used as FSACS and then sent to the Big Holding Tank, as described in Section VI (Compliance Projects) of this Report, for reprocessing and recovery of acid values. 

Because sampling cannot take place instantaneously, it may be also necessary at times for FSA, including FSA that does not meet minimum customer
specifications, to enter the FSA Storage Tank (C4T80) before sampling results are obtained and/or a customer for this FSA is found. If Mosaic fails to find a customer for the contents of the FSA Storage Tank (C4T80) within ninety (90) days, the
contents shall be handled in compliance with the RCRA Subtitle C program. 
 At any given time prior to the 90 day storage limit, the contents of the FSA
Storage Tank (C4T80) may be:

Prior to commencement of operations of the BHT, FSA produced for use as a cleaning solution may continue to be managed consistent with Mosaic’s
consolidated waste management practices submittal dated September 8, 2015. Following commencement of operations of the BHT, FSA produced for use as a cleaning solution may be used and then must be sent to the Big Holding Tank, as described in
Section VI (Compliance Projects) of this Report, for reprocessing and recovery of acid values. 
 Mosaic Bartow has one primary transfer line, FSA
Shipping Line that serves to transport FSA between the FSA Storage Tank and Truck Loading. The location of the transfer line is illustrated in Figure 5. The line designation and cleaning frequency is listed in Table 3.

Mosaic will refurbish Reuse Water Tank (Figure 13) to serve as an interchangeable backup tank for the BHT system, which may be used in services other than
BHT when not operating as a BHT (which other use shall not alter or nullify the status of the backup tank as a BHT Recovery Unit or preclude its use as a part of Upstream Operations, if appropriate). The backup tank will be used during cleaning
and/or maintenance of the BHT tank. Cleaning waste from the BHT backup tank will be handled in the same way as the cleaning waste from the BHT itself as described in Section 2. Phosphoric Acid Plant Cleaning Procedures of the BMP. 

In addition, new or upgraded pumps, motors, small pump tanks, and instrumentation may be needed to ensure the return to the BHT cleaning wastes and spills
and leaks of: (1) phosphoric acid, sulfuric acid, FSA, SACS, PACS, FSACS, or BHT Effluent; or (2) NHACS, Process Wastewater, or Phosphogypsum Stack System Wastewater when mixed with any of the preceding solutions due to spills, leaks, or
cleaning of leaks and spills. Project 1 necessarily coincides with Project 2 below.

 Project 2: Cleaning Solution Return Piping 

Mosaic will install new piping to enable Mosaic to: (1) clean phosphoric acid transfer lines from the Phosphoric Acid Plant to the #3 DAP/MAP and #4 DAP
Granulation Plants and return those cleaning wastes to the BHT; (2) clean BHT Recovery Units located in the Granulation Plants and return those wastes to the BHT; and (3) clean FSA system and return wastes to the BHT. 

2. Project Operations 

The wash solution system will be comprised of the BHT and the SACS make up tank(s), along with pumps and piping to supply cleaning solution to units that
are part of Upstream Operations or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units. 
 Phosphogypsum Stack System Wastewater, Process
Wastewater, fresh water, condensate or other water sources will be mixed with sulfuric acid, FSA, phosphoric acid or BHT Effluent in the SACS wash make up tank(s) or BHT. The equipment and lines that are part of Upstream Operations or are identified
as Mixed-Use, Grandfathered, or BHT Recovery Units may be washed with SACS either from the BHT or the SACS wash make up tank and the solutions may be returned to the BHT. 

In addition, the BHT will enable Mosaic to recover the value of wastes generated from the use of SACS, FSA, FSACS, PACS, Non-Hazardous Aqueous Cleaning
Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, BHT Effluent from pipes, tanks, process equipment, or other storage or transport units that: (i) are part of Upstream Operations, (ii) serve to manage, store, or
transport Bevill-Exempt Wastes; or (iii) are identified as Mixed-Use, Grandfathered Units, or BHT Recovery Units in this Report. In accordance with the BMP, the BHT will also enable Mosaic to recover spills and leaks in Containable Impervious
Areas described in Section VII (Containment of Phosphoric Acid Product Leaks and Spills) of this Report. The BHT may also receive transfers from the GHT in accordance with Section VI. B.2. Project Operations. 

The BHT shall in turn return the recoverable streams into Upstream Operations where their values are recovered or managed through the following: (See Figure
1: BHT Inputs and Effluents) 
  

	 	a.	as an intermediate wash on the filter, prior to the final cake wash, to inhibit scale formation. This wash ultimately circulates back to the reactor (attack tank); and/or 

	 	b.	as direct make up to the phosphoric acid reactors; and/or 

	 	c.	neutralized in the Pond Water Neutralization System (see Section IV.E 

	 	 	Ammoniated Process Wastewater Transfer (BHT Recovery Units)) above and then added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactors; and/or

B. GHT Related Projects 

1. Project Descriptions 

Project 3: Granulation Plant Re-Slurry System (#3 DAP7) 

Mosaic will install product recovery tank, hopper, piping, steam feed, valves, agitator, and pumps to recover wet fertilizer product. The resulting slurry
will be fed to the acid scrubber system for consumption in the granulation process. 
 Project 4: Granular Holding Tank and Wash
Solution System in the Granulation Plant 
 Mosaic will install two Granular Holding Tank
(GHT)8 systems- one in #3 DAP/MAP plant and the other in #4 DAP plant. The GHT plus piping, pumps, and instrumentation (together the “GHT system”) will transport and recirculate wash
solution between GHT Recovery Units and the GHT and consume the wash solution in the granulation plants (#3 DAP/MAP and #4 DAP) as specified in Section VI.B.2 below. 

Project 5: Upgrade Granulation Plants’ Pads and Sumps 

Mosaic will modify or install, as needed, containment pads and sumps in each granulation plant to improve the capture of spills, leaks, and cleaning
solutions so materials may be returned to the granulation process via the GHT. This will include the #3 DAP/MAP Tank Farm and the #4 DAP Tank Farm as identified in this Report. 

2. Project Operations 

 
  

7 DAP4 already has an operational re-slurry system. 

8 Although Mosaic plans to install more than one GHT, for simplicity this Report will use the singular
“GHT” to describe any and all GHTs that will be installed at Mosaic’s Bartow facility.

 Mosaic Bartow 

Facility Report 
  

 The GHT system will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS,
Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, or GHT Effluent from pipes, tanks, process equipment, or other storage or transport units identified as GHT Recovery Units or manage those wastes as
described in Section 3. Granulation Plants Cleaning Procedures of the BMP. In accordance with the BMP, the GHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this report. 

 

	 	A.	The GHT shall in turn reuse or recover the recoverable streams as follows: 

  

	 	a.	consumed in the acid scrubber system for consumption in the granulation process; and/or 

  

	 	b.	consumed directly into the granulation reactor; and/or 

  

	 	c.	added to the re-slurry system; and/or 

  

	 	d.	recirculated to clean GHT Recovery Units. 

  

	 	B.	In GHT cleaning situations identified in Section 3 Granulation Plants Cleaning Procedures - GHT Recovery Units, of the BMP, Mosaic may transfer the contents of the GHT to the BHT if they are RCRA non-hazardous. If
the contents of the GHT are hazardous only for the RCRA corrosivity characteristic (pH £ 2), Mosaic may transfer the contents to the BHT no more than two times per calendar year. The GHT shall then be
washed with a cleaning solution (SACS, PACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH £ 2), it may be
transferred to the BHT not more than two times per calendar year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System. 

 

	 	C.	In addition to GHT cleaning situations in B, in non-routine situations (such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures, hurricanes or similar weather events or
unexpected problems during startups) and if the GHT is (or imminently will be) at or above 90% (full), Mosaic may transfer GHT Effluent if non-hazardous or hazardous only for the RCRA corrosivity characteristic (pH
£ 2) to the BHT, in order to create additional capacity in the GHT, until the GHT’s capacity is at 50%, provided that Mosaic: 

 

	 	i)	Manages use of the GHT to BHT transfer line by locking the valve on the transfer line or a system interlock requiring a code to activate; 

 

	 	ii)	Obtains approval from its area manager to make the transfer; and 

  

	 	iii)	Includes information on each transfer in its reports to the EPA and FDEP as required in Paragraph 41 of the CD. 

If Mosaic chooses not to reuse or recover the GHT Effluent as described above, the GHT Effluent must instead be managed in accordance with RCRA.

 VII. Containment of Phosphoric Acid Product Spills and Leaks 
 Any impervious9 manufacturing or storage areas not identified in this section as Containable Impervious Areas are considered to be Non-Segregable Areas. 

Non-Segregable Areas 

Approximately 20% of Mosaic Bartow’s Phosphoric Acid Plant’s impervious surfaces have 40-mil HDPE liner installed beneath them. In several areas,
the concrete pad is sloped towards concrete-lined trenches (denoted by orange lines in Figure 10) that transport any leaks and spills to the Phosphogypsum Stack System. Process Wastewater flows through the trenches at a rate of approximately 50,000
– 60,000 GPM to the Phosphogypsum Stack system. Due to the engineered slope of the concrete pad in these areas and the configuration of the Phosphoric Acid Plant, small spills and leaks of phosphoric acid, sulfuric acid, and FSA onto the
concrete pad cannot be segregated (“non-segregable areas”) and are mixed in the trenches with the Process Wastewater flowing to the Phosphogypsum Stack system and managed pursuant to Appendix 5, BMP. Mosaic may manage small spills and
leaks of phosphoric acid, sulfuric acid, and FSA within the concrete areas of the Phosphoric Acid plant (delineated by redlines in Figure 10) in accordance with the BMP. 
  

 

9 Note, the use of the term “impervious” in this section does not refer to a particular
definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to penetration, such as concrete, liners, steel, epoxy, etc. The term impervious in this section does not include gravel or soil.

recovered in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations under any applicable law. 
 
Other Areas 
 Any leak or spill of a hazardous material, including phosphoric acid and sulfuric acid, that is not contained within the
Containable Impervious Areas or Non-Segregable Areas of the plant shall be managed in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations under any applicable law. 

VIII. Process Water (Wastewater) Treatment Plant (Reverse Osmosis Plant) 

Mosaic has installed a reverse osmosis plant at the Bartow facility to reduce Process Wastewater inventory (Diagram 1: Reverse Osmosis Unit Block Flow). The
system consumes Process Wastewater and produces a permeate water of sufficient quality to be either discharged through a National Pollutant Discharge Elimination System (NPDES) permitted outfall or used as a fresh water source for the facility. The
reject water, concentrated Process Wastewater, is returned to the Phosphogypsum Stack System. 
 The reverse osmosis plant has several stages of treatment
to produce the final permeate. A description of these stages follows. 
  

	 	1)	First Stage: Process Wastewater is pumped to any of five Ultra Filtration (UF) trains. UF concentrate flows to the Phosphogypsum Stack System. UF permeate feeds the UF permeate tank (T20.001) or is used to back
flush UF membranes and is returned to the Phosphogypsum Stack System. 

  
 32 

Table of Contents

 Mosaic Bartow 

Facility Report 
  

	 	2)	Second Stage: 1st Stage permeate from the 1st Stage permeate tank (T20.001) is pumped to any of five 2nd Stage trains. 2nd Stage concentrate flows to the Phosphogypsum Stack System. 2nd Stage
permeate feeds the 2nd Stage permeate tank (T30.001). 

  

	 	3)	Third Stage: 2nd Stage permeate from the 2nd Stage permeate tank (T30.001) is pumped to any of five 3rd Stage trains. 3rd Stage concentrate flows to either the Phosphogypsum Stack System or the
1st Stage permeate tank (T20.001). 3rd Stage permeate feeds the 3rd Stage permeate tank
(T40.001). 

  

	 	4)	Fourth Stage: 3rd Stage permeate from the 3rd Stage permeate tank (T40.001) is pumped to any of five 4th Stage trains. 4th Stage concentrate flows to the Clean in Place (CIP) water tank (T70.001).
4th Stage permeate flows primarily to the product water tank (T50.001). 4th Stage permeate is pumped from the product water tank (T50.001) to
the main gate or returned to the plant to offset fresh water. 4th Stage permeate feeds a minimal amount to the caustic dilution tank (T92.002).
4th Stage permeate is tested online for pH and conductivity. If 4th Stage permeate is out of spec, it is recycled or diverted to the rainwater
collection tank (T06.200) so it can be pH adjusted, if needed then released to the Phosphogypsum Stack System. 

 Cleaning Solutions:
Acid and caustic cleaning solutions are circulated through each of the units as needed to CIP. Acid cleaning solution is also back flushed through the first stage membranes for Enhanced Back Flush (EBF). The sulfuric acid solution concentration is
typically 1% or less. After circulation the solutions are drained to the spent CIP neutralization tank (T06.100), where the pH is adjusted (>2.0 or <12.5) before being released to the Phosphogypsum Stack System. 

Wastes generated from Mosaic Bartow’s reverse osmosis plant shall be managed pursuant to Paragraph 18(a) of the Consent Decree. Mosaic may change the
manner in which Mosaic’s Bartow reverse osmosis plant operates without requiring prior approval by FDEP or EPA, provided that Mosaic (i) continues to manage such wastes pursuant to Paragraph 18(a) of the Consent Decree; and
(ii) notifies FDEP or EPA of such changes within 90 Days of implementing such changes. In any event, cleaning solutions and filters must be managed in accordance with RCRA.

 IX. Proposed Phosphoric Acid Production-Related
Operations 
 Mosaic has advised EPA and FDEP that it is considering one or more of the following projects at its Bartow facility, but planning
has not evolved to where detailed information is available. 
 Figure 13 depicts Upstream, Mixed-Use, BHT Recovery Units and Grandfathered units. In the
event that Mosaic reconfigures its Facility in accordance with Figure 14 and Figure 12, then Figure 14 and Figure 12 shall replace Figure 13 as identifying Upstream Operations, Downstream Operations, Grandfathered Units, BHT Recovery Units, and
Mixed-Use Units for the Phosphoric Acid Plant.

 However, the Consent Decree does not bind Mosaic to implement the proposed
project(s) as depicted in Diagram 2, Diagram 3, Figure 12, and Figure 14. If Mosaic chooses to implement any changes through a different process than that depicted in Diagram 2, Diagram 3, Figure 12 and Figure 14, this Report shall be modified prior
to implementation pursuant to Section XVIII (Modifications) of the Consent Decree and EPA and FDEP will determine whether the new process as designed involves Upstream Operations, Mixed-Use Units, Grandfathered Units, BHT Recovery Units or
Downstream Operations and amend the Facility Report to memorialize those determinations consistent with the descriptions below. Such determination shall be conditioned upon the new process being built substantially as designed. If the new process
deviates from that standard, EPA and FDEP will determine whether the new process as built involves Upstream Operations, Mixed-Use Units, Grandfathered Units, BHT Recovery Units or Downstream Operations and amend the Facility Report to memorialize
those determinations consistent with the descriptions below.

 I. Introduction 

All capitalized terms not otherwise defined in this Facility Report shall have the meaning set forth in the Consent Decree. 

A. Purpose 
 The purposes of this Facility Report are
to: 
  

	 	1.	Identify Mosaic Fertilizer, LLC’s (Mosaic) Upstream Operations (Upstream), Animal Feed Ingredient Production (AFIP), and Downstream Operations (Downstream) at its New Wales Facility (Mosaic New Wales), its

 II.
Background3 
 Mosaic New Wales’s primary commercial products are solid ammoniated
phosphate fertilizers monoammonium phosphate (MAP), diammonium phosphate (DAP), and MicroEssentials® (MES) and the non-ammoniated animal feed ingredients monocalcium phosphate (Biofos ®), dicalcium phosphate (Dynafos®), sodium calcium phosphate (Nexfos®). DAP is
manufactured in three production trains designated as #1 DAP/MAP and #2 DAP (#2 DAP East and #2 DAP West). MAP is also produced in #1 DAP/MAP, as well as plants designated as #3 granular MAP (GMAP) and powdered MAP (PMAP). Ammonia and phosphoric
acid are the primary reactants for MAP and DAP and are consumed in the production of these fertilizers on-site. Animal feed ingredients are manufactured in the AFIP area. 

Phosphoric acid is produced by the digestion of phosphate rock with sulfuric acid. Mosaic manufactures phosphoric acid in one production plant with three
distinct reactors on-site. The reaction yields phosphoric acid and phosphogypsum (gypsum). Gypsum is filtered from the phosphoric acid on rotating pan filters, slurried with Process Wastewater in Gypsum Slurry Tanks,

exhaustive description of the Facility or its operations.

 and the resultant slurry is pumped to a lined Phosphogypsum Stack (gypstack). Because the production of
phosphoric acid is a water-intensive process and water is used throughout the process (e.g., as acid dilution water, in the ball mills, evaporators, condensers, and as a pipe and tank cleaning agent), approximately 2.5 billion gallons of Process
Wastewater is constantly stored in and circulating throughout the facility’s Phosphogypsum Stack System. 
 Mosaic deposits slurried gypsum in a
60-mil high density polyethylene (HDPE) lined Phosphogypsum Stack located southeast of the facility. The lined South Gypsum Stack operates in conjunction with the existing Phosphogypsum Stack System. 

Mosaic’s New Wales Phosphogypsum Stack System is partially lined with 60-mil HDPE (within Lined Emergency Surge Pond-1 (LESP-1) and Lined Emergency
Surge Pond-2 (LESP-2)). The pond system consists of the main cooling pond and connecting North, East, and West cooling channels, unlined Auxiliary Holding Pond (AHP), LESP-1 and LESP-2 and Northeast sump located directly east and south of the
production complex. Mosaic operates the Phosphogypsum Stack System under an Industrial Wastewater Facility Permit issued by the Florida Department of Environmental Protection (FDEP). 

III. First Saleable Products at Mosaic New Wales 

The line marking the division between Upstream and Downstream Operations lies at the point of generation of the First Saleable Product. The following are the
First Saleable Products at Mosaic New Wales: 

	 	1.	30% acid, when fed to #1DAP/MAP, #2 DAP, #3 GMAP, or any other Downstream Operation; 

	 	2.	54% acid (greater than 1% solids), when fed to #1DAP/MAP, #2 DAP, #3 GMAP, transported off-site or used in any other Downstream Operation; and 

	 	3.	54% Merchant Grade Acid (less than 1% solids) or any greater concentration of acid not associated with non-ammoniated Animal Feed Ingredient Production (AFIP). 

Downstream Operations at Mosaic New Wales are associated with the storage, transport or use of these First Saleable Products in MAP, DAP and
MicroEssentials® operations. Other First Saleable Products that are part of Upstream Operations are the non-ammoniated animal feed ingredients monocalcium phosphate (Biofos ®), dicalcium
phosphate (Dynafos ®) and sodium calcium phosphate (Nexfos ®). 

IV. Phosphoric Acid Production – Phosphoric Acid Plant 

Figure 11identifies Upstream Operations, Mixed-Use Units and BHT Recovery Units within Mosaic New Wales’ Phosphoric Acid Plant. Figure 2 identifies AFIP
Units within Mosaic New Wales’ AFIP Plant. 
 Mosaic New Wales Phosphoric Acid Plant has approximately 80% impervious surfaces. Below-grade concrete
ditches throughout the Plant convey Process Wastewater from the Plant to the Phosphogypsum Stack System at a flow rate of approximately 86,000 GPM. The main Process Wastewater return ditches within the plant are composed of high performance
concrete.

 A. Standard Acid Flow Configuration

 The Phosphoric Acid Plant produces three concentrations of phosphoric acid for use in fertilizing manufacturing – 30% P2O54, 40% P2O5, and 54% P2O55. The 30% acid that
is not used directly as feedstock to fertilizer manufacturing is further processed to 54% P2O5 in Upstream Operations. The standard
phosphoric acid manufacturing process described below is illustrated in a process flow diagram Figure 1. Deviations from the standard acid flow configuration are necessary on periodic short-term intervals. 

Mosaic New Wales produces phosphoric acid in three reactors designated as the Phosphoric acid Reactor East-Train (0048), the Phosphoric acid Reactor
West-Train (0049), and the Phosphoric acid Reactor Third-Train (0051). Approximately 70% of the acid from all reactors mixes at the 30% Clarifier Feed Storage Tank “East” (“30East Tank” or “30E Tank” - 0061) and the 30%
Clarifier Feed Storage Tank “West” (“30West Tank” or “30W Tank” - 0062). The remaining 30% is sent directly to the following three evaporator feed tanks: 30% Evaporator Feed Tank “East” (“30East Evap Feed
Tank” - 0025), 30% Evaporator Feed Tank “West” (“30West Evap Feed Tank” - 0024), and 30% Evaporator Feed Tank “Third” (“30Third Evap Feed Tank” - 0069). Prior to mixing at the 30East Tank (0061) and
30West Tank (0062), the acid flows as follows: 
 Phosphoric acid Reactor East-Train (Upstream): 

Post-reactor, the approximate 30% phosphoric acid slurry is pumped to the East Tilting Pan Filter where gypsum solids are filtered from the
phosphoric acid. Gypsum is pumped to the South Gypsum Stack and the unclarified 30% phosphoric acid filtrate flows into the East Filter Filtrate Seal Tank. From the East Filter Filtrate Seal Tank, the 30% unclarified acid is pumped to any of the
following tanks: 30E Tank (0061), 30W Tank (0062), 30East Evap Feed Tank (0025), 30West Evap Feed Tank (0024) or 30Third Evap Feed Tank (0069); 

Phosphoric acid Reactor West-Train (Upstream): 

Post-reactor, the approximate 30% phosphoric acid slurry is pumped to the West Tilting Pan Filter where gypsum solids are filtered from the
phosphoric acid. Gypsum is pumped to the South Gypsum Stack and the unclarified 30% phosphoric acid filtrate flows into the West Filter Filtrate Seal Tank. From the West Filter Seal Tank, the unclarified 30% acid is pumped to any of the following
tanks: the 30E Tank (0061), the 30W Tank (0062), 30East Evap Feed Tank (0025), 30West Evap Feed Tank (0024) or 30Third Evap Feed Tank (0069); 

Phosphoric acid Reactor Third-Train (Upstream): 

Post-reactor, the approximate 30% phosphoric acid slurry is pumped to the Third Tilting Pan Filter where gypsum solids are filtered from the
phosphoric acid. Gypsum is pumped to the South Gypsum Stack and the unclarified 30% phosphoric acid filtrate flows into the Third Filter Filtrate Seal Tank. From the Third Filter Filtrate Seal Tank the unclarified 30% acid is pumped to any of the
following tanks: the 30E Tank (0061), the 30W Tank (0062), 30East Evap Feed Tank (0025), 30West Evap Feed Tank (0024), or 30Third Evap Feed Tank (0069). 
  

 

4 All P2O5 concentrations are approximate and fluctuate slightly. 

5 Note that although the terms P2O5 and phosphoric acid (H3PO4 ) are used interchangeably, the concentrations are not
interchangeable. Mosaic manufactures phosphoric acid, however, in this document we refer to the concentration of the acid in terms of
P2O5 concentration, rather than phosphoric acid concentration. P2O5 concentration can be converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to an approximate concentration of P2O5 by multiplying by 0.7242.

Table of Contents

 Mosaic New Wales 

Facility Report 
  

 In addition, Mosaic New Wales operates a re-slurry system that recovers product that is wet and cannot be
recovered through the dry side’s reclaim system; instead, Mosaic mixes the product in a re-slurry tank with 30% acid, and/or fresh water as a batch process. This slurry is then fed back into the acid scrubber system for recovery. 

MAP, DAP and MES manufacturing operations are Downstream Operations; however, the units that are listed below are Recovery Units and are identified within
the perimeters shown in Figure 10: Containable Impervious Areas in Granulation. 
 The following equipment in the Granulation Plants are BHT Recovery
Units. Wastes from BHT Recovery Units may be recovered into Upstream Operations as designated in this Facility Report or to the BHT itself as described in Section VI (Compliance Projects 1 and 2) of this Report and Sections 3 and 6 of the BMP: 

 

	 	a.	MAP Sludge Tank (0026); 

	 	b.	#1 DAP Day Tank (0501)

	 	c.	#3 GMAP Acid Day Tank (1071)

	 	d.	#2 DAP Day Tank (0280)

 The following equipment in the Granulation Plants are GHT Recovery Units. Wastes from

 A. BHT and Cleaning Solution Return Piping Projects

 1. Project Description 

Project 1: Big Holding Tank and Wash Solution System in the Phosphoric Acid Plant 

The Big Holding Tank and wash solution system (together designated the “BHT System”) project in the Phosphoric Acid Plant shall install new tank(s)
or modify existing tanks, piping, and controls to enable Mosaic to recover the value of wastes as specified in Section VI. A.2. below. 
 Mosaic will have
two BHTs to serve as the BHT system. One of the tanks may be used in services other than BHT when not operating as a BHT (which other use shall not alter or nullify the status of the backup tank as a BHT Recovery Unit or preclude its use as a part
of Upstream Operations, if appropriate). The BHT backup tank will be used during cleaning and/or maintenance of the BHT tank. Cleaning waste from the BHT backup tank will be handled in the same way as the cleaning waste from the BHT itself as
described in Section 2. Phosphoric Acid Plant Cleaning Procedures of the BMP. 
 In addition, new or upgraded pumps, motors, small pump tanks, and
instrumentation may be needed to ensure the return to the BHT cleaning wastes and spills and leaks of: (1) phosphoric acid, sulfuric acid, SACS, PACS, or BHT Effluent; and (2) NHACS, Process Wastewater, or Phosphogypsum Stack System
Wastewater when mixed with any of the preceding solutions due to spills, leaks, or cleaning of leaks and spills. Project 1 necessarily coincides with Project 2 below. 

Project 2: Cleaning Solution Return Piping 

Mosaic will install new piping to enable Mosaic to: (1) clean phosphoric acid transfer lines from the Phosphoric Acid Plant to the 1 DAP/MAP, #2 DAP and
#3 GMAP Granulation Plants and return those cleaning wastes to the BHT; and (2) clean BHT Recovery Units located in the Granulation Plants and return those wastes to the BHT. 

2. Project Operations 

The wash solution system will be comprised of the BHT and the SACS make up tank(s), along with pumps and piping to supply cleaning solution to units that
are part of Upstream Operations or AFIP, or identified as Mixed-Use, Grandfathered, or BHT Recovery Units. 
 Phosphogypsum Stack System Wastewater,
Process Wastewater, fresh water, condensate or other water sources will be mixed with sulfuric acid, phosphoric acid, or BHT Effluent in the SACS wash make up tank(s) or BHT. The equipment and lines that are part of Upstream Operations or are
identified as Mixed-Use, Grandfathered, or BHT Recovery Units may be washed with SACS either from the BHT or the SACS wash make up tank and the solutions may be returned to the BHT. 

In addition, the BHT will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS, Non-Hazardous Aqueous Cleaning Solution,
Process Wastewater, Phosphogypsum

 Stack System Wastewater, BHT Effluent from pipes, tanks, process equipment, or other storage or transport
units that: (i) are part of Upstream Operations or AFIP, (ii) serve to manage, store, or transport Bevill-Exempt Wastes; or (iii) are identified as Mixed-Use, Grandfathered Units, or BHT Recovery Units in this Facility Report. In
accordance with the BMP, the BHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this Report. The BHT may also receive transfers from the GHT in accordance with Section VI. Compliance
Projects, B.2. Project Operations. 
 The BHT shall in turn return the recoverable streams into Upstream Operations where their values are recovered or
managed through the following (Diagram 1: BHT Inputs and Effluents): 

	 	a.	as an intermediate wash on the filter, prior to the final cake wash, to inhibit scale formation. This wash ultimately circulates back to the reactor (attack tank); and/or 

	 	b.	as direct make up to the Phosphoric acid reactors; and/or 

	 	c.	added to the rock grinding circuit where it will be pH adjusted using limestone slurry; this mixture ultimately ends up in the slurry fed into the phosphoric acid reactors; and/or 

	 	d.	discharged to the Phosphogypsum Stack System, if in compliance with the LDR standards set forth in 40 C.F.R. Part 268, Subpart D; and/or 

	 	e.	If the P2O5 content is at least 8%, the BHT Effluent may be placed in the evaporator feed tanks for P2O5 recovery.

 B. GHT Related Projects 

1. Project Descriptions 

Project 4: Upgrade Granulation Plants’ Pads and Sumps (Upgraded Recovery System) 

Mosaic will modify or install, as needed, containment pads and sumps in each granulation plant to improve the capture of spills, leaks and cleaning solutions
so materials may be returned to the granulation process via the GHT. This will include the four (4) granulation plants at New Wales - #1 DAP/MAP, #3 GMAP, #2 DAP East and #2 DAP West, as identified in the New Wales Facility Report. 

Project 5: Granulation Plant Re-slurry System (DAP2 East and West)8

 Mosaic will install a product recovery tank, hopper, piping, steam feed, valves, agitator, and pumps to recover wet fertilizer product from
the DAP 2 East & West plants. The resulting slurry will be fed to the acid scrubber system for consumption in the granulation process. 
 Project 6: Granular Holding Tank and Wash Solution System in the Granulation Plant 
 Mosaic will install two Granular
Holding Tank (GHT)9 systems- one in DAP2 East & West and the other in #1 DAP/MAP and #3 GMAP (Figure 14). The GHT plus piping, pumps, and instrumentation (together the “GHT
system”) will transport and recirculate wash solution between GHT Recovery Units and the GHT and consume the wash solution in the granulation plants (DAP2 East & West, #1 DAP/MAP and #3 GMAP) as specified in Section VI.B.2 below. 

2. Project Operations 

The GHT system will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process
Wastewater, Phosphogypsum Stack System Wastewater, or GHT Effluent from pipes, tanks, process equipment, or other storage or transport units identified as GHT Recovery Units or manage those wastes as described in Section 3. Granulation Plants
Cleaning Procedures of the BMP. In accordance with the BMP, the GHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this Report. 

 

	 	A.	The GHT shall in turn reuse or recover the recoverable streams as follows: 

  

	 	a.	consumed in the acid scrubber system for consumption in the granulation process; and/or 

  

	 	b.	consumed directly into the granulation reactor; and/or 

  

	 	c.	added to the re-slurry system; and/or 

  

 

8 DAP1 and GMAP3 already have reslurry systems for each plant.

	 	d.	recirculated to clean GHT Recovery Units; and/or 

  

	 	B.	In GHT cleaning situations identified in Section 4, GHT Cleaning - GHT Recovery Units, of the BMP, Mosaic may transfer the contents of the GHT to the BHT if they are RCRA non-hazardous. If the contents of the GHT
are hazardous only for the RCRA corrosivity characteristic (pH < 2), Mosaic may transfer the contents to the BHT no more than two times per calendar year. The GHT shall then be washed with a cleaning solution (SACS, PACS, Process
Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH < 2), it may be transferred to the BHT not more than two times per calendar year. If the solution is
non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System. 

  

	 	C.	In addition to GHT cleaning situations in B, in non-routine situations (such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures, hurricanes or similar weather events or
unexpected problems during startups) and if the GHT is (or imminently will be) at or above 90% (full), Mosaic may transfer GHT Effluent if non-hazardous or hazardous only for the RCRA corrosivity characteristic (pH < 2) to the BHT, in
order to create additional capacity in the GHT, until the GHT’s capacity is at 50% provided that Mosaic: 

  

	 	i)	Manages use of the GHT to BHT transfer line by locking the valve on the transfer line or a system interlock requiring a code to activate; 

 

	 	ii)	Obtains approval from its area manager to make the transfer; and 

  

	 	iii)	Includes information on each transfer in its reports to the EPA and FDEP as required in Paragraph 41 of the CD. 

If Mosaic chooses not to reuse or recover the GHT Effluent as described above, the GHT Effluent must instead be managed in accordance with RCRA.

 VII. Containment of Phosphoric Acid Product Spills and Leaks 

Any impervious10 manufacturing or storage areas not identified in this section as Containable
Impervious Areas are considered to be Non-Segregable Areas. 
 Non-Segregable Areas 

Mosaic New Wales Phosphoric Acid Plant has approximately 80% impervious surfaces with about 50% of it being acid brick and vinyl ester resin
lined. The concrete pad is sloped towards concrete-lined trenches that transport any leaks and spills to the Phosphogypsum Stack System (Figure 8). Process water flows through the trenches at a rate of approximately 86,000 GPM to the Phosphogypsum
Stack system. Due to the engineered slope of the concrete pad in these areas and the configuration of the Phosphoric Acid Plant, small spills and leaks of phosphoric acid and sulfuric acid onto the concrete pad cannot be feasibly segregated
(“non-segregable areas”) and are mixed in the trenches with the Process Wastewater flowing to the Phosphogypsum Stack system and managed pursuant to Appendix 5, BMP. Mosaic may manage small spills and leaks of acid within the concrete
areas of the Phosphoric Acid plant (Figure 8) in accordance with the BMP.

10 Note, the use of the term “impervious” in this section does not refer to a particular
definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to penetration, such as concrete, liners, steel, epoxy, etc. The term impervious in this section does not include gravel or soil.

 Spills and leaks of phosphoric acid, sulfuric acid, and cleaning
solutions onto impervious areas designated by Figure 9 and Figure 10 (“containable impervious areas”) shall be separately contained and then recovered in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations
under any applicable law. 
 Other Areas 

Any leak or spill of a hazardous material, including phosphoric acid and sulfuric acid, that is not contained within the Containable
Impervious Areas or Non-Segregable Areas of the plant shall be managed in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations under any applicable law. 

VIII. Proposed Phosphoric Acid Production Operations 

Mosaic has advised EPA and FDEP that it is considering one or more of the following projects at its New Wales facility, but planning has not evolved to where
detailed information is available. 
 Figure 11 depicts Upstream, Mixed-Use, and BHT Recovery Units. In the event that Mosaic reconfigures its Facility in
accordance with Figure 12 and Figure 13 or Diagrams 4-7, then Figure 12 and Figure 13 shall replace Figure 11 as identifying Upstream Operations, Grandfathered Units, BHT Recovery Units and Mixed-Use Units for the Phosphoric Acid plant. 

However, the Consent Decree does not bind Mosaic to implement the proposed project(s) as depicted in Figure 12 and Figure 13 or Diagrams 4-7. If Mosaic
chooses to implement any changes through a different process than any of those depicted in Figure 12 and Figure 13 or Diagrams 4-7 in this Facility Report, then it shall be modified prior to implementation pursuant to Section XVIII (Modification) of
the Consent Decree and EPA and FDEP will determine whether the new process as designed involves Upstream Units, Mixed-Use Units, BHT Recovery Units or Downstream Units and amend the Facility report to memorialize those determinations consistent with
the descriptions below. Such determination shall be conditioned upon the new process being built substantially as designed. If the new process deviates from that standard, EPA and FDEP will determine whether the new process as built involves
Upstream Operations, Mixed-Use Units, Grandfathered Units, BHT Recovery Units or Downstream Operations and amend the Facility Report to memorialize those determinations consistent with the descriptions below.

 II. Background4 
 Mosaic Riverview’s
primary commercial products include solid ammoniated phosphate fertilizers: monoammonium phosphate (MAP) and diammonium phosphate (DAP), MicroEssentials® (MES) as well as fluorosilicic acid
(FSA). DAP is manufactured in two production trains designated as #5 DAP and #6 DAP/MAP. MAP is also produced in #5 DAP or # 6 DAP/MAP. Ammonia and phosphoric acid are the primary reactants for MAP, DAP and MicroEssentials® and are consumed in the production of ammoniated fertilizers on-site. 
 Phosphoric acid is produced
by the digestion of phosphate rock with sulfuric acid. Mosaic manufactures phosphoric acid in one production plant, with two distinct reactors on-site. The reaction yields phosphoric acid and phosphogypsum (gypsum). Gypsum is filtered from the
phosphoric acid on rotating pan filters, slurried with Process Wastewater in Gypsum Slurry Tanks, and the resultant slurry is pumped to a lined Phosphogypsum Stack. Because the production of phosphoric acid is a water-intensive process and water is
used throughout the process (e.g., as acid dilution, in the ball mills, evaporators, condensers, and as a pipe and tank cleaning agent), approximately 500 million to 1.5 billion gallons of Process Wastewater are constantly stored in and
circulating throughout the facility’s Phosphogypsum Stack System. 
 Mosaic Riverview deposits slurried gypsum in a clay-lined Phosphogypsum Stack
(gypstack). An expansion to the gypstack is complete and is lined with 60-mil high density polyethylene (HDPE). The gypstack and the expansion are located northeast of the facility, east of US Hwy 41. The

 combined lined gypstack operates in conjunction with the 80-mil HDPE lined Phosphogypsum Stack system. 

Mosaic’s Riverview Phosphogypsum Stack system is lined with 80-mil HDPE. The pond system consists of a transfer pond located directly east of the
production complex, and the pond’s connecting ditches. Mosaic Riverview operates the Phosphogypsum Stack System under an Industrial Wastewater Facility Permit issued by the Florida Department of Environmental Protection (FDEP). 

III. First Saleable Products at Mosaic 

The line marking the division between Upstream and Downstream Operations lies at the point of generation of the First Saleable Product. Mosaic Riverview
generates two phosphoric acid First Saleable Products used as direct feedstocks to MAP or DAP production: 

	 	●	 	30% phosphoric acid that is routed to MAP or DAP production rather than to further concentration steps; 

	 	●	 	54% clarified phosphoric acid (greater than 1% solids) that is also routed to either MAP or DAP production. 

Riverview also produces fluorosilicic acid (FSA) as a First Saleable Product. Downstream operations at Mosaic Riverview are associated with the storage,
transport or use of FSA and of the phosphoric acid First Salable Products in MAP, DAP, and MES operations. 
 
IV. Phosphoric Acid and FSA Production - Phosphoric Acid Plant 
 Figure 13 identifies Upstream Operations, BHT Recovery Units, Mixed-Use
Units, and Grandfathered Units within Mosaic Riverview’s Phosphoric Acid Plant. 
 Mosaic Riverview’s Phosphoric Acid Plant has approximately
90% impervious surfaces and approximately 50% of the Plant has 40-mil HDPE liner installed below the concrete acid pads within contained areas. Below-grade concrete or acid-brick lined trenches and underground polyethylene piping throughout the
Plant convey Process Wastewater from the Plant to the Phosphogypsum Stack system at a flow rate of approximately 60,000 GPM. The main Process Wastewater return ditches within the plant are composed of high performance concrete. The entire phosphoric
acid plant is encompassed by a bentonite slurry wall that vertically intersects the limestone/bedrock layer. 
 
A. Standard Acid Flow Configuration 
 The Phosphoric Acid Plant produces three concentrations of phosphoric acid for use in fertilizer
manufacturing: 30% P2O55, 43%
P2O5, and 54% P2O56. The 30% acid that is not used directly as feedstock to fertilizer manufacturing is further processed to 54% P2O5 in Upstream Operations. The 
  

 
 5 All concentrations of P2O5 are approximate and fluctuate slightly. 

6 Note that although the terms P2O5 and phosphoric acid (H3PO4) are used interchangeably, the concentrations are not
interchangeable. Mosaic manufactures phosphoric acid, however, in this document we refer to the concentration of the acid in terms of
P2O5 concentration, rather than phosphoric acid concentration. P2O5 concentration can be converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to an approximate concentration of P2O5 by multiplying by 0.7242.

 standard phosphoric acid manufacturing process described below is illustrated in process flow diagram
(Figure 4). Deviations from the standard acid flow configuration are necessary on periodic short-term intervals. 
 Mosaic Riverview produces phosphoric
acid in two reactors designated as the Phosphoric Acid Reactor and the Dorrco Phosphoric Acid Reactor. The acid from both reactors mixes at the 30% Clarifier Feed Tank (“30 CFT” - 55T001). Prior to mixing at the 30 CFT (55T001), the acid
flow is as follows: 
 Phosphoric Acid Reactor: 

Post-reactor, unclarified 30% acid is pumped through the # 3 Filter to the #3 Filter #1 Filtrate Tank (41T001) and/or through the #1
Filter #1 Filtrate Tank (212306) then to the 30 CFT (55T001). 
 Phosphoric Acid Dorrco Reactor: 

Post-reactor, unclarified 30% acid is pumped to the Phosphoric Acid Dorrco Digester (“Digester”) for aging (additional gypsum
crystallization/solids formation) and then through the #1 Filter to the #1 Filter #1 Filtrate Tank (212306) and/or through the #2 Filter to the # 2 Filter # 1 Filtrate tank (31T24) and then to the 30 CFT (55T001).

 C. Phosphoric Acid Transfer to Downstream Operations

  

	1)	Acid Transfer between the Phosphoric Acid Plant and the Dock Tanks (BHT Recovery Units) 

Mosaic Riverview has two primary transfer lines that serve to transport 54% phosphoric acid from the Phosphoric Acid Plant to the Dock
Tanks. The East 54 Overs Line and the West 54 Overs transfer lines transfer 54% clarified phosphoric acid from 54% Clarifier to East Dock Tank (25T11) or West Dock Tank (25T10). 

All transfer lines described above are cleaned with cleaning solution to remove precipitated solids and scale to maintain acceptable
pressure levels and acid flow rates. The locations of the transfer lines are illustrated in Figure 7 and Figure 8. The estimated line lengths and cleaning frequencies are listed in Table 4. 

 

	2)	Acid Transfer between the Phosphoric Acid Plant and the #6 DAP/MAP (BHT Recovery Units) 

Mosaic Riverview has two primary transfer lines that serve to transport 30% phosphoric acid from the Phosphoric Acid Plant to #6 DAP/MAP.

	4)	Acid Transfer between the Phosphoric Acid Plant and Truck Loading (BHT Recovery Units) 

Riverview has one transfer line, the East 54 Clarifier feed, which serves to transport unclarified 54% phosphoric acid from the Phosphoric
Acid Plant to Truck Loading. The line is cleaned with cleaning solution to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. The location of the transfer line is illustrated in Figure 5. The estimated
line lengths and cleaning frequencies are listed in Table 2. 
 D. Fluorosilicic Acid (FSA)
Standard Process Configuration 
 Mosaic Riverview recovers fluoride vapors from several evaporators. The recovery of fluoride vapors
produces FSA. A generic depiction of the FSA production process is illustrated in Diagram 1. 
 FSA is produced as part of the first and second stage
evaporation of phosphoric acid. Evaporators #1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 each have a FSA recovery unit, also called a “Swift Tower,” integrated with a barometric condenser. The Swift Tower receives gas emitted from the concentration
of 28% P2O5 to 43% P2O5
(for first stage evaporators – #1, 2, 3, 4, 9 and 10) and 43% P2O5 to 54%
P2O5 (for second stage evaporators - #4, 5, 6, 7, 8) through evaporation. The gas is condensed in the Swift Tower and the liquid is
continuously recirculated through a seal tank and back through the Swift Tower to maintain the seal and operation of the FSA Swift Tower. 
 FSA is not
always produced. When FSA is not being produced for sale or use as a cleaning solution, the gases pass through the Swift Tower to the barometric condenser, there is no recirculation of FSA through the Swift Tower, and therefore FSA is not produced.
Even when FSA is not being produced, the FSA Seal Tank remains an essential part of the Phosphoric Acid Evaporator by sealing the Swift Tower downleg. 

When FSA is being produced for sale, recirculated liquid will continue to absorb fluoride vapors until the desired strength of FSA is obtained. FSA for sale
is a solution of approximately 23-26% strength and specific gravity of 1.20-1.23. 
 Once the FSA reaches the desired strength for sale, a slip stream
from the recirculation line between the FSA Seal Tank and FSA Swift Tower is sent to the FSA Scrubber Liquor Tank (25T12). In the FSA Scrubber Liquor Tank (25T12) the solution is isolated and tested for meeting customer specifications.
Solutions meeting customer specifications in the Scrubber Liquor tank are transferred to the FSA Storage Tanks: FSA “A” Tank (25T07), FSA “B” Tank (25T08), and FSA “C” Tank (25T09) and sold to customers off-site.

 Prior to commencement of operations of the BHT, if the solution does not meet the minimum customer specifications, within 90 days of that
determination, the contents from the FSA Scrubber Liquor Tank (25T12) must be: 
  

	 	1.	Returned to the #1 Evaporator Feed Tank (26T01), #3 Evaporator Feed Tank (26T03) or #4 Evaporator Feed Tank (26T04) for reprocessing and recovery of acid value when FSA is being recovered for sale; or

	 	2.	Sent to the Phosphoric Acid Reactors for reprocessing and recovery; or

	 	5.	Used as FSA Cleaning Solution (FSACS) and then sent to the Big Holding Tank, as described in Section VI. Compliance Projects of this Report for reprocessing and recovery of acid values; or 

	 	6.	Discharged to the Phosphogypsum Stack System, if in compliance with the land disposal restriction (LDR) standards set forth in 40 C.F.R. Part 268, Subpart D. 

Because the sampling cannot take place instantaneously, it may be also necessary at times to transfer FSA from the FSA Scrubber Liquor Tank to the FSA
“A” Tank (25T07), FSA “B” Tank (25T08), or FSA “C” Tank (25T09) before sampling results are obtained or a customer for this FSA is found.

 B. Granulation Plants

 Mosaic Riverview’s granulation process consists of two basic parts: (1) the wet (e.g., reactor, acid scrubber system); and
(2) the dry side (e.g., granulator, dryer). 
 In addition, Mosaic Riverview will install a re-slurry system that recovers product that becomes wet
and cannot be recovered through the dry side’s reclaim system. Mosaic will mix the product in a re-slurry tank with 30% acid, fresh water and/or GHT effluent as a batch process. This slurry will then be fed back into the acid scrubber system
for recovery. 
 MAP, DAP and MES manufacturing operations are Downstream Operations; however, the units listed below are Recovery Units and are
identified within the perimeters shown in Figure 12. 
 The following equipment in the Granulation Plant are BHT Recovery Units. Wastes from BHT Recovery
Units are recovered into Upstream Operations as designated in this Report or to the BHT itself as described in Section VI. Compliance Projects (Projects 1 and 2) of this Report and Sections 3 and 6 of the BMP: 

 

	 	●	 	#5 DAP 54% Acid Tank (33T01); 

	 	●	 	#6 DAP 54% Acid Tank (“60K”- 30T04); 

	 	●	 	East Dock Tank (25T11); and 

	 	●	 	West Dock Tank (25T10); 

 The following equipment in the Granulation Plants are GHT Recovery Units. Wastes
from GHT Recovery Units are recovered into the granulation process as designated in this Report or to the GHT itself as described in Section VI. Compliance Projects (Projects 3, 4, and 5) of this Report and Sections 3 and 6 of the BMP: 

 

	 	a.	Granulation re-slurry system; 

	 	b.	Granulation acid scrubbers; 

	 	c.	Granulation reactor; 

	 	d.	Granulator;

 Mosaic Riverview 

Facility Report 
  

 The projects described below are not all the projects in Appendix 6 (Compliance Schedule) to the Consent
Decree but are the projects that are recovery related – the BHT, GHT and reslurry systems. Timeframes for completion of the projects are found in Appendix 6 (Compliance Schedule) to the Consent Decree. 

Projects 1 and 2 comprise a plan that will enable Mosaic Riverview to clean Upstream, Mixed-Use, Grandfathered, and BHT Recovery Units and recover value
from the wastes as described below. 
 Projects 3, 4, and 5 are projects related to the Downstream Operations in Granulation and recovery of material in
the granulation process. 
 A. BHT and Cleaning Solution Return Piping Projects 

1. Project Descriptions 

Project 1: Big Holding Tank and Wash Solution System in the Phosphoric Acid Plant 

The Big Holding Tank and wash solution system (together designated the “BHT system”) project in the Phosphoric Acid Plant shall install new tank(s)
piping, and controls to enable Mosaic to recover the value of wastes, as specified in Section VI.A.2 Project Operations below. 
 Mosaic will install two
new BHTs for the BHT system. One of the tanks may be used in services other than BHT when not operating as a BHT (which other use shall not alter or nullify the status of the backup tank as a BHT Recovery Unit or preclude its use as a part of
Upstream Operations, if appropriate). The BHT backup tank(s) will be used during cleaning and/or maintenance of the BHT tank. Cleaning waste from the BHT backup tank will be handled in the same way as the cleaning waste from the BHT itself as
described in Section 2. Phosphoric Acid Plant Cleaning Procedures of the BMP. 
 In addition, new or upgraded pumps, motors, small pump tanks, and
instrumentation may be needed to ensure the return to the BHT cleaning wastes and spills and leaks of: (1) phosphoric acid, sulfuric acid, FSA, SACS, PACS, FSACS, or BHT Effluent; or (2) NHACS, Process Wastewater, or Phosphogypsum Stack
System Wastewater when mixed with any of the preceding solutions due to spills, leaks, or cleaning of leaks and spills to the BHT. Project 1 necessarily coincides with Project 2 below. 

Project 2: Cleaning Solution Return Piping 

Mosaic will install new piping to enable Mosaic to: (1) clean phosphoric acid transfer lines from the Phosphoric Acid Plant to the #6 DAP/MAP and #5 DAP
Granulation Plants and the Dock Tanks and return those cleaning wastes to the BHT; (2) clean BHT Recovery Units located in the Granulation Plants and return those wastes to the BHT; and (3) clean FSA system and return those wastes to the
BHT. 
 2. Project Operations

Table of Contents

 Mosaic Riverview 

Facility Report 
  

 The wash solution system will be comprised of the BHT and the SACS make up tank(s), along with pumps and
piping to supply cleaning solution to units that are part of Upstream Operations, or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units. 

Phosphogypsum Stack System Wastewater, Process Wastewater, fresh water, condensate or other water sources will be mixed with sulfuric acid, FSA, phosphoric
acid or BHT Effluent in the SACS wash make up tank(s) or BHT. The equipment and lines that are part of Upstream Operations or are identified as Mixed-Use, Grandfathered, or BHT Recovery Units may be washed with SACS either from the BHT or the SACS
wash make up tank and the solutions may be returned to the BHT. 
 In addition, the BHT will enable Mosaic to recover the value of wastes generated from
the use of SACS, FSA, FSACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process Wastewater, Phosphogypsum Stack System Wastewater, BHT Effluent from pipes, tanks, process equipment, or other storage or transport units that: (i) are part of
Upstream Operations, (ii) serve to manage, store, or transport Bevill-Exempt Wastes; or (iii) are identified as Mixed-Use, Grandfathered Units, or BHT Recovery Units in this Report. In accordance with the BMP, the BHT will also enable
Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this report. The BHT may also receive transfers from the GHT in accordance with Section VI. Compliance Projects, B.2. Project Operations of this Report.

 The BHT shall in turn return the recoverable streams into Upstream Operations where their values are recovered or managed through the following (Figure
1): 

	 	a.	as an intermediate wash on the filter, prior to the final cake wash, to inhibit scale formation. This wash ultimately circulates back to the reactor (attack tank); and/or 

	 	b.	as direct make up to the phosphoric acid reactors; and/or 

	 	c.	neutralized in the Pond Water Neutralization System and then added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactors; and/or 

	 	d.	discharged to the Phosphogypsum Stack System, if in compliance with the LDR standards set forth in 40 C.F.R. Part 268, Subpart D; and/or 

	 	e.	if the P2O5 content is at least 8% the BHT Effluent may be placed in the evaporator feed tanks for P2O5 recovery.

 B. GHT Related Projects 

1. Project Descriptions 

Project 3: Granulation Plant Re-slurry System 

Mosaic will install product recovery tank, hopper, piping, steam feed, valves, agitator, and pumps to recover wet fertilizer product. The resulting slurry
will be fed to the acid scrubber system for consumption in the granulation process. This may be one system for both granulation plants, or it may be two systems, one for each granulation plant. 

Project 4: Granular Holding Tank and Wash Solution System in the Granulation Plant 

Mosaic will install either one common or two Granular Holding Tank (GHT) systems for the #5 DAP and #6 DAP/MAP granulation plants (Figure 16). The GHT plus
intermediate holding tanks, piping, pumps, and instrumentation (together the “GHT system”) will transport and recirculate wash solution between GHT Recovery Units and the GHT and consume the wash solution in the granulation plants (#5 DAP
and #6 DAP/MAP) as specified in Section VI.B.2 Project Operations below. 
 Project 5: Upgrade Granulation Plants’ Pads and
Sumps As Needed 
 Mosaic will modify or install, as needed, containment pads and sumps in each granulation plant to improve the capture of
spills, leaks, and cleaning solution so materials may be returned to the granulation process via the GHT, as identified in the Riverview Facility Report. 

2. Project Operations 

The GHT system will enable Mosaic to recover the value of wastes generated from the use of SACS, PACS, Non-Hazardous Aqueous Cleaning Solution, Process
Wastewater, Phosphogypsum Stack System Wastewater, or GHT Effluent from pipes, tanks, process equipment, or other storage or transport units identified as GHT Recovery Units or manage those wastes as described in Section 3. Granulation Plants
Cleaning Procedures of the BMP. In accordance with the BMP, the GHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section VII of this report.

Facility Report 
  

	 	A.	The GHT shall in turn reuse or recover the recoverable streams as follows: 

  

	 	a.	consumed in the acid scrubber system for consumption in the granulation process; and/or 

  

	 	b.	consumed directly into the granulation reactor; and/or 

  

	 	c.	added to the re-slurry system; and/or 

  

	 	d.	recirculated to clean GHT Recovery Units. 

  

	 	B.	In GHT cleaning situations identified in Section 3: GHT Cleaning and Non-Routine Transfer Situations of the BMP, Mosaic may transfer the contents of the GHT to the BHT if they are RCRA non-hazardous. If the
contents of the GHT are hazardous only for the RCRA corrosivity characteristic (pH £ 2), Mosaic may transfer the contents to the BHT no more than two times per calendar year. The GHT shall then be washed
with a cleaning solution (SACS, PACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH £2), it may be transferred to
the BHT not more than two times per calendar year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System. 

  

	 	C.	In addition to GHT cleaning situations in B, in non-routine situations (such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures, hurricanes or similar weather events or
unexpected problems during startups) and if the GHT is (or imminently will be) at or above 90% (full), Mosaic may transfer GHT Effluent if non-hazardous or hazardous only for the RCRA corrosivity characteristic (pH
£ 2) to the BHT, in order to create additional capacity in the GHT, until the GHT’s capacity is at 50% (full), provided that Mosaic: 

 

	 	i)	Manages use of the GHT to BHT transfer line by locking the valve on the transfer line or a system interlock requiring a code to activate; 

 

	 	ii)	Obtains approval from its area manager to make the transfer; and 

  

	 	iii)	Includes information on each transfer in its reports to the EPA and FDEP as required in Paragraph 41 of the CD. 

If Mosaic chooses not to reuse or recover the GHT Effluent as described above, the GHT Effluent must instead be managed in accordance with RCRA.

 VII. Containment of Phosphoric Acid Product Spills and Leaks

 Any impervious8 manufacturing or storage areas not identified in this section as
Containable Impervious Areas are considered to be Non-Segregable Areas. 
 Non-Segregable Areas 

Approximately 50% of Mosaic Riverview’s Phosphoric Acid Plant’s impervious areas have 40-mil HDPE liner installed beneath them. The concrete pad is
sloped towards concrete-lined trenches (denoted by orange lines in Figure 10) that transport any leaks and spills to the Phosphogypsum Stack System. Process Wastewater flows through the trenches at a rate of approximately 60,000 GPM to the
HDPE-lined Phosphogypsum Stack system. Due to the engineered slope of the concrete pad in these areas and the configuration of the Phosphoric Acid Plant, small spills and leaks of phosphoric acid, sulfuric acid, and FSA onto the concrete pad cannot
be feasibly segregated (“non-segregable areas”) and are mixed in the trenches with the Process Wastewater flowing to the Phosphogypsum Stack system and managed pursuant to Appendix 5, BMP to the Consent Decree. Mosaic may manage small
spills and leaks of phosphoric acid, sulfuric acid, and FSA within the concrete areas of the Phosphoric Acid plant) in accordance with the BMP. There are some areas in the Phosphoric acid area that are not concreted and they are shown with redlines
in Figure 10. 
  
  

8 Note, the use of the term “impervious” in this section does not refer to a particular
definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to penetration, such as concrete, liners, steel, epoxy, etc. The term impervious in this section does not include gravel or soil.

 INTRODUCTION 

Mosaic has developed Appendix 5: Best Management Practices Plan (hereinafter either “BMP” or “Plan”) to reduce
unintended (and seek to eliminate unauthorized) inputs of phosphoric acid, sulfuric acid, fluorosilicic acid (FSA), SACS, PACS, and FSACS to Process Wastewater entering the Phosphogypsum Stack System. Where possible, Mosaic will capture and reuse
these acid loses. 
 Through the BMP, Mosaic has established procedures to address the management, tracking, and reporting of phosphoric
acid, sulfuric acid, and FSA leaks and spills for four of its fertilizer production facilities—Bartow, New Wales, Riverview, and Uncle Sam1—in areas of the phosphoric acid plants (post
first-stage filtration, e.g. bird or belt filters), including acid clarification and evaporation, and in the granulation plants. The specific details of the BMP for the phosphoric acid and granulation plants are discussed in the Sections that follow
and the referenced Attachments. Where noted, certain BMP procedures are dependent upon the commencement of operation of the compliance projects set forth in Appendix 6 (Project Narrative & Compliance Schedules), to the Consent Decree. 

SECTION 1: PHOSPHORIC ACID PLANTS LEAK/SPILL DETECTION 

SYSTEMS AND RESPONSE PROCEDURES 

1.1        General 

Mosaic will implement two approaches to increase the likelihood of detecting non-segregable acid leaks, spills and process upsets: operator
inspections and process stream conductivity monitoring, which are discussed in greater detail below. While conductivity monitoring is exclusive to the Process Wastewater system (non-segregable areas), operator inspections also serve to identify
observable leaks and spills of acids regardless of the area of the plant where they occur – non-segregable, contained impervious, or outside contained impervious area. 

1.2        Release Reporting 

Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill of any
hazardous material listed in Attachment A, Table 1 BMP Actionable Volumes (hereinafter, “Table 1 Materials”) pursuant to this BMP. This BMP does not 

 
 1 Mosaic’s Faustina facility is not covered under this Appendix and Mosaic’s Plant City facility is the subject of a separate BMP Plan developed under a separate consent decree.

Table of Contents

 
relieve Mosaic of its obligation to provide any such notifications under applicable federal, state, or local laws. 

1.3        Inspections 

Operators shall visually inspect the plant for leaks and/or spills of phosphoric acid, sulfuric acid, and FSA during their normal rounds a
minimum of twice per shift and document the inspections. The operator shall correct any leaks from valves, flanges, pumps, or any other equipment that can be readily and safely corrected at the time of discovery. The incident shall be recorded in
the tracking database known as AON Risk Management software or any other future data collection system which replaces or supplements AON Risk Management software (hereinafter, collectively referred to as “AON”). Any leaks or spills in
excess of the applicable volume listed in Attachment A, Table 1 BMP Actionable Volumes (hereinafter “BMP Actionable Volume (Table 1)”) shall be reported to management for further action and recorded in AON. Reporting responsibilities are
outlined in Mosaic’s Spill Reporting Policy and Procedure. 

1.4        Conductivity System Description: Non-Segregable
Spills/Leaks2 
 New Wales, Bartow, Riverview, and Uncle Sam shall
monitor key outgoing streams (see Attachment B) with a conductivity system to enable the continuous detection of changes in conductivity that indicate occurrence of detectable acid leaks and spills. Each key outgoing stream shall have a conductivity
probe to continuously measure the conductivity of the Process Wastewater as shown in Attachment B of this Plan. The conductivity of the return Process Wastewater stream shall be displayed on the operators’ distributive control system, see
Attachment B of this Plan. 
 If acid leaks or spills into an outgoing water or Process Wastewater stream, the conductivity of the water
or Process Wastewater increases because the acid has a higher conductivity than the water. Visual alarms (see example in Attachment B of this Plan) shall be triggered if the conductivity increases beyond the set alarm limits for a 5-minute interval.
Upon triggering of such an alarm, the area around the probe will be investigated. Individual conductivity probe locations are found in Attachment B of this Plan. 

Individual conductivity probes will alarm based on the preliminary trigger values set for each probe found in Attachment B of this Plan. The
targets shown in Attachment B of this Plan are the initial temperature compensated conductivity targets for Bartow, New Wales, Riverview and Uncle Sam, respectively. Pursuant to Section 9: BMP Performance Standards, of this BMP, Mosaic will
monitor the conductivity probes at Bartow, New Wales, and Riverview for a year after June 30, 2015 and will monitor the conductivity probes at Uncle Sam for a year after January 31, 2016 to ensure settings are correct for alerting
operations to leaks and spills within the limits of the probes when properly operated and calibrated. 
 When a visual alarm triggers, the
operator shall inspect that piece of equipment or area of the plant for any problems and take appropriate measures to stop or minimize the release and minimize further impacts (see Attachment B of this Plan). 

 
 2 Non-Segregable Areas are described in Facility Reports “Containment of Phosphoric Acid Product Spills and Leaks.”

Table of Contents

 The conductivity system shall be maintained in accordance with specific manufacturer
recommendations or acceptable industrial practices and updated as needed. Conductivity meters will be checked monthly and the instruments calibrated if necessary. The calibration dates and probe alarm limits shall be documented in the maintenance
management system that is in place at the time. Maintenance and calibration procedures are found in Attachment B of this Plan. 

1.5        Tracking/Recording 

AON shall be used to track leaks and spills and the remedial measures taken to address a leak or spill. The area management, engineering, and
environmental departments shall use AON to ensure the prompt and proper execution of remedial measures. When plant personnel identify a leak, spill or process upset (e.g. filtrate tank overflow), resulting in a release, appropriate remedial measures
shall be taken as outlined below. A record of the incident shall be entered within 24 hours of the incident into AON to log and track releases of Table 1 Materials. Supervisors shall be trained to enter incidents into AON. AON tracks specific
information including date and time of release, date and time of report, a description of the incident, volume of the material, type of material, and additional supporting information. AON generates emails to specific personnel that identify the
severity and location of the incident. Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill, except for minor leaks or spills that already have been remedied. 

1.6        Reporting, Recovery, and Remedial Measures

 Management and environmental staff shall be notified of leaks or spills with a reasonable potential to reach or exceed
the BMP Actionable Volume (Table 1) as quickly as possible in order to verify the volume of the leak or spill and ensure that it is properly reported, documented, and corrected pursuant to this BMP. 

Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill, except for
minor leaks or spills that already have been remedied. AON shall be used to track leaks and spills and the immediate actions taken to address a leak or spill. The area management, engineering, and environmental departments shall use AON to ensure
the prompt and proper execution of remedial measures. 

1.6.1            Non-Segregable Areas of the Phosphoric Acid Plants: 

1.6.1.1 Reporting 

Any leak or spill of FSA, sulfuric acid, SACS, PACS, FSACS or phosphoric acid into a non-segregable area, as described in
each Facility’s Facility Report, which is detected as a result of visual inspections, audible alarms, conductivity monitoring, or operational detections (e.g. pressure losses) must be logged into AON. See Section 1.6.1.2: Remedial
Measures, of this BMP. 
 If the leak or spill has the potential to exceed the BMP Actionable Volume (Table 1) in a
rolling 24-hour period, appropriate management and environmental staff shall be notified and the leak or spill shall be properly reported, documented, and corrected pursuant to this BMP.

Table of Contents

 1.6.1.2 Remedial Measures 

If any leak or spill of a Table 1 Material into a non-segregable area, as described in each Facility’s Facility Report,
with a reasonable potential to approach a BMP Actionable Volume (Table 1) within any rolling 24-hour period is discovered, Mosaic will take the following measures: 
  

	 	1)	 Investigate potential release sources. 

  

	 	2)	 Address any issues found. 

  

	 	a.	 Stop the release if possible, such as by flow diversion or by closing the release gate. 

 

	 	b.	 Generate a work order if needed to correct the issue. 

 

	 	3)	 Document the release in AON. 

  

	 	4)	 Report the release to EPA, FDEP, or LDEQ pursuant with the Consent Decree. 

This BMP does not relieve Mosaic of its obligation to comply with any federal, state, or local laws applicable to such a
leak or spill. 
 1.6.2            Containable Impervious Areas: 

1.6.2.1 Reporting 

Any leak or spill of a Table 1 Material into a containable impervious area, as described in each Facility’s Facility
Report and identified in Figure 10 (Bartow), Figure 9 (New Wales), Figure 7 (Uncle Sam), and Figure 11 (Riverview), must be logged into AON but does not need to be reported to EPA if recovered to a tank containing the same chemical or the Big
Holding Tank (BHT), described in Section 6: Cleaning Solution System Operation, of this BMP. 
 1.6.2.2 Recovery and Remedial
Measures 
 Any leak or spill of a Table 1 Material into a containable impervious area, as described in each
Facility’s Facility Report and identified in Figure 10 (Bartow), Figure 9 (New Wales), Figure 7 (Uncle Sam), and Figure 11 (Riverview), shall be recovered back to a tank containing the same chemical or input into the BHT via sump pump, vacuum
truck, or other means or, if unrecoverable due to contamination or location of the spill, must be managed in compliance with the RCRA Requirements. This BMP does not relieve Mosaic of its obligation to comply with any other federal, state, or local
laws applicable to such a leak or spill. 
 1.6.3            Other Areas:

 1.6.3.1 Reporting 

Any leak or spill of a Table 1 Material that is not contained within a non-segregable area or a containable impervious area,

 SECTION 2:  PHOSPHORIC ACID PLANT CLEANING
PROCEDURES 
 2.1        General

 SACS, FSA, PACS, or FSACS are periodically used to wash lines, filters, or other equipment within the phosphoric acid
plant, including evaporation and clarification. The primary purpose for continuing to use SACS is to recover sulfate value and offset the amount of virgin sulfuric acid used. The primary purpose for continuing to use FSA and FSACS is to recover FSA
value. The primary purpose for using PACS is to recover P2O5 value. The recovery of these solutions will contribute to decreasing the
total dissolved solids in the Process Wastewater ponds. 
 SACS, FSA, FSACS and PACS shall be managed as shown in Diagram 1: Big Holding
Tank Cleaning Solution and Solids Management Plan. Following commencement of operations of the Big Holding Tank (BHT), no SACS or PACS shall be placed into the Phosphogypsum Stack System, other than indirectly via the approved uses below. SACS PACS,
FSA and FSACS shall be routed to the BHT (described in Section 7: Minimization of Operational Phosphoric Acid Inputs, of this Appendix) for consumption in the phosphoric acid plant so the BHT Effluent’s value can be realized through the
following uses described in each Facility’s Facility Report: 
  

	 	1.	 Added to the filter prior to the final cake wash to inhibit scale formation. The filtrate from this wash is sent as recycle acid to the reactor
(attack tank); or 

	 	2.	 Used as direct make up to the reactor attack tank; or 

	 	3.	 Added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactor(s); or

	 	4.	 If the P2O5 content is at least
8%, placed in the evaporator feed tank(s) for P2O5 recovery. 

If for any reason the BHT Effluent is not recovered as outlined above, it must satisfy the RCRA land disposal restriction (LDR) standards
prior to discharge to the Phosphogypsum Stack System (see Diagram 1). 
 Following commencement of operations of the BHT, if FSA has been
transferred to BHT Recovery Units for sale or cleaning,3 no FSA or FSACS shall be placed into the Phosphogypsum Stack System from BHT Recovery Units, other than indirectly via the following: 

	 	1.	 Returned to the evaporator feed tank(s) that directly feed FSA-producing evaporators when FSA is being recovered for sale and/or internal
consumption; or 

	 	2.	 Sent to phosphoric acid reactors for reprocessing and recovery of FSA values; or 

	 	3.	 Sent to the BHT as described in Section VI (Compliance Projects) of the respective Facility’s Facility Report for recovery of FSA values; or

	 	4.	 Used as FSACS and then sent to the BHT for reprocessing and recovery of acid values. 

If for any reason FSA or FSACS from BHT Recovery Units is not recovered as outlined above, it must 

 
 3 FSA is not always recovered. When FSA is not being recovered for sale or cleaning, the gases pass through the Swift Tower to the barometric
condenser, there is no recirculation of FSA through the Swift Tower, and therefore FSA is not produced. Even when FSA is not being recovered, the FSA Seal Tank remains an essential part of the Phosphoric Acid Evaporator by sealing the Swift Tower
downleg.

 SECTION 3:  GRANULATION PLANTS CLEANING PROCEDURES5 

3.1        General 

Mosaic’s intent is to minimize losses and to conserve and recover resources whenever feasible. Solutions and solids generated from
cleaning granulation equipment other than BHT Recovery Units as described in the Facility’s Facility Report shall either be recovered in the granulation process or characterized to determine if they are hazardous under the RCRA Requirements for
corrosivity (pH £ 2 or pH 3 12.5) and/or toxicity (Table 2). If the materials are not recovered to the granulation process and are hazardous, they shall be
handled according to the RCRA Requirements. If these materials are not recovered to the granulation process and are non-hazardous, they can be discharged to the Phosphogypsum Stack System. 

3.2        Line Cleaning 

All lines within the granulation plant shall be washed with an aqueous cleaning solution (i.e., Process Wastewater, Phosphogypsum Stack
Water, NHACS, SACS, PACS, FSACS, FSA or GHT Effluent). All cleaning solutions that enter the boundary of the granulation plant shall be handled according to Section 3.1: General, of this BMP. 

3.3        Phosphoric Acid Tank Cleaning (BHT Recovery Units)

 Following commencement of operations of the BHT, the following general steps shall be used in the cleaning of any
phosphoric acid storage tank in the granulation plants (BHT Recovery Units). Empty the tank by feeding the remaining acid to the Granulation process or recovering phosphoric acid back to the phosphoric acid clarification process or another
phosphoric acid tank within the Granulation area. Wash the tank with an aqueous cleaning solution (i.e., Process Wastewater, Phosphogypsum Stack Water, NHACS, SACS, PACS, FSACS, FSA or BHT Effluent) if needed. Fill the tank with cleaning solution
and recirculate to facilitate cleaning for an appropriate period of time (typically 12-48 hours), until the scale is adequately removed. The wash may be repeated multiple times until adequately cleaned, and the wash solution (including entrained
solids) sent to the BHT. Solids that are removed with high pressure cleaning with NHACS or by other mechanical means will be dewatered. The liquid portion of the dewatered solids will be recovered to the BHT. If the dewatered solids are
non-hazardous, they will be transferred to the Phosphogypsum Stack System. If they are hazardous, they will be handled in compliance with the RCRA Requirements. 

At Bartow, ammonia may be added as a scale softening agent to DAP Pond water, Phosphogypsum Stack System Wastewater, or Process Wastewater
and the resulting cleaning solution is used to clean phosphoric acid storage tanks in the granulation plant. This non-hazardous spent wash solution shall only be recovered to the DAP process pond.

operations of the Granular Holding Tank (GHT), the resulting stream shall be sent to the GHT. High pressure cleaning with NHACS or other mechanical means may be used to remove hard scale and buildup or to strip rubber from the equipment. Solids that
are removed from the Tailgas Scrubber system will be characterized and handled in compliance with the RCRA Requirements. 
 
3.5        Granulation Dry Side Equipment Cleaning - GHT Recovery Units 
 The
wash solution, such as Process Wastewater, DAP Pond water, Phosphogypsum Stack Wastewater, or NHACS is collected either in the Acid Scrubber or the Reactor and a continuous flow is sent to the Dry Side Equipment, such as the granulator, dryer,
cooler, elevators, screens, milling equipment and the associated piping. The cooler may be washed as part of the Dry Side Equipment wash or separately. High pressure cleaning with NHACS or other mechanical means may be used to remove hard scale.
Following commencement of operations of the GHT, liquids (including entrained solids) will be recovered to the GHT. Solids that are removed with high pressure cleaning or mechanical means will be dewatered, if needed. Following commencement of
operations of the GHT, any liquid portion of these solids will be recovered to the GHT. The solids will be recovered back to the granulation process through either the dry reclaim system or the re-slurry system. 

3.6        GHT Cleaning and Non-Routine Transfer Situations

 3.6.1    GHT Cleaning 

Following commencement of operations of the GHT, the following general steps shall be used in cleaning of the GHT(s) and the Riverview and
New Wales GHT intermediate tanks. The tanks shall be emptied by recovering as much liquid (with entrained solids) as possible back into the granulation process and/or the BHT. Any residual volume that is hazardous only for RCRA corrosivity (pH £2) and cannot be recovered into the granulation process may be transferred to the BHT not more than two times per calendar year. The GHT shall then be washed with a cleaning solution (SACS, PACS, Process
Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH £2), it may be transferred to the BHT; not more than two times per calendar
year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System.

 6.2        Granulation
Areas9 
 The granulation containment pads shall be designed to collect
rainfall, spills, leaks, and cleaning solutions within plant areas. The collection sumps for these containment pads shall pump to the granulation plant scrubbers, re-slurry tank, GHT or, if non-hazardous, may be discharged to a permitted National
Pollutant Discharge Elimination System (NPDES) outfall. The sumps will be designed with pH probes that will allow storm water run-off during high rainfall to be diverted to the Phosphogypsum Stack System if pH > 2.0 or to a permitted NPDES
outfall. This will eliminate excessive rain water getting into the GHT, diluting it and also leading to the tank level being high. The granulation plant acid scrubbers and re-slurry tank are designed to recover fertilizer materials, product and raw
materials for consumption in the granulation process. 
 Cleaning solutions in the Granulation area (except for cleaning solutions from
BHT Recovery Units) shall be managed as follows: 

	 	•	 	 If the resulting stream from the cleaning process is non-hazardous, the solution may be discharged directly to the Phosphogypsum Stack System or
recovered in the granulation process via the GHT. 

	 	•	 	 If the resulting stream is hazardous, then the resulting solution shall be recovered in the granulation process via the GHT for recovery of

 SECTION 7:  MINIMIZATION OF OPERATIONAL PHOSPHORIC
ACID INPUTS 
 7.1        Background

 During normal operation of the Phosphoric Acid Plants, various activities may result in the operational input of
phosphoric acid to impervious areas within the battery limits of the Phosphoric Acid Plants or to the Phosphogypsum Stack System. These activities include sample collection, slide gate valve operation, clearing plugged piping or process equipment,
and similar routine operations. Operators shall minimize the volume of such phosphoric acid inputs by releasing only the amount of acid necessary in order to accomplish the task and recover acid loss where practicable. Intermittent operational
inputs of phosphoric acid to impervious areas or the Phosphogypsum Stack System are unavoidable and shall not be considered malfunctions, leaks, or spills, unless the volume from one of these inputs to the Phosphogypsum Stack System exceeds the BMP
Actionable Volume (Table 1). Any continuing release resulting from these activities may indicate the need for maintenance activity and shall be entered into AON and the computerized maintenance management system (currently MAXIMO) for correction.

 7.2        Operational Input Minimization

 7.2.1     Sample Collection 

Samples of phosphoric acid or reactor slurry collected for purposes of plant process control shall be returned to the process. 

7.2.2     Clarifier/Valve/Line Operational Releases 

Operational inputs of phosphoric acid from clarifier unplugging, valve operation and line unplugging shall be minimized to the extent
practicable, releasing only the amount of acid necessary out of the primary containment area in order to accomplish the task and recovery where practicable. 

7.3        Response 

7.3.1     Releases Outside Containment Areas 

All reasonable measures shall be taken to avoid releases of phosphoric acid outside of plant containment areas. This BMP does not relieve
Mosaic of its obligation to comply with any federal, state, or local laws applicable to such a release. 

7.3.2     Emergency Response

 SECTION 9:  BMP PERFORMANCE STANDARDS

 9.1        Performance Criteria

 The goals of the BMPs are listed in the Introduction of this Appendix. Mosaic shall develop appropriate performance
criteria consistent with the BMPs herein for the purpose of evaluating trends and improving performance. The performance criteria include progress review of the construction and utilization of the projects in Appendix 6 (Project
Narrative & Compliance Schedules) to the Consent Decree, BMP training, and implementation of the procedures set forth herein. 

For two years from the Effective Date of the CD, semi-annual meetings will be held with the State Agency and EPA to review BMP performance.
Meetings will occur annually after the first two years and may be adjusted based on the completion of the implementation schedule. 

9.2        Performance Criteria for Spill and Leak Detection

 An initial data collection period of 12 months will be used to establish baseline performance criteria for spills, leaks,
and other releases. Mosaic will monitor the conductivity probes at Bartow, New Wales, and Riverview for a year after June 30, 2015 and will monitor the conductivity probes at Uncle Sam for a year after January 31, 2016. Once BMP
performance criteria and a baseline are established, Mosaic shall review the criteria quarterly. Based upon the reviews, BMPs will be updated as warranted to minimize leaks, spills, and other releases. Mosaic shall initiate additional review of the
BMP Program under the following circumstances: 
  

	 	•	 	 At any time during a calendar quarter when two or more leak or spill events of phosphoric acid, sulfuric acid or FSA into “non-segregable
areas” at the same facility have occurred that exceed the quantity shown in Table 1: BMP Actionable Volumes (Table 1) in a rolling 24-hour period. 

  

	 	•	 	 At any time during a calendar quarter when two or more leak or spill events of phosphoric acid, sulfuric acid or FSA inside a “containable
impervious area” at the same facility have occurred that exceed the quantity shown in Table 1: BMP Actionable Volumes (Table 1) in a rolling 24-hour period. 

 

	 	•	 	 At any time during a calendar quarter when two or more leak or spill events of phosphoric acid, sulfuric acid or FSA have occurred outside of
non-segregable or containable impervious areas at the same facility that exceed the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) Reportable Quantity. 

9.3        Reporting/Auditing 

Reporting shall be conducted pursuant to the Consent Decree and the aforementioned Performance Criteria.

 SECTION 10:  BMP TRAINING 

10.1    Overview Training 

An overview of BMP issues and procedures shall be included in the periodic environmental compliance training provided to all affected
employees, such as the managers, superintendents, supervisors, operators, and maintenance personnel in the phosphoric acid, FSA, AFIP, and granulation plants. 

10.2    Area Specific Employee Training 

Employees within phosphoric acid, FSA, AFIP, and granulation plants shall receive initial training on RCRA and the Consent Decree, including
the BMPs, through classes and materials developed by Mosaic. Employee training is part of project implementation and is found in Appendix 6 (Project Narrative & Compliance Schedules) to the Consent Decree. Detailed refresher training on the
Consent Decree, including RCRA and the BMPs, shall be conducted for all affected employees every year. Updated training shall be provided as BMP projects are completed, and will commence within two months of establishing a baseline under
Section 
9.2, and if the BMP is modified. Records of training shall be maintained by the Training Department. 
 10.3    Contractors
 
 The relevant portions of this BMP shall be incorporated into contractors’ site-specific training where appropriate.

 Maintenance 

Each Mosaic concentrate plant uses manufacturer recommended calibration procedures specific to the type of probe. The four calibration methods that are
being used are Bench Calibration using a User-Supplied Wire, Bench Calibration Using a Foxboro Calibration Plug and Solution Calibration and the Decade resistor box. Table 5 below shows methods that are being used at each of the sites. Probes are
removed, cleaned and dried every time prior the calibration procedure is performed.

PHOSPHOGYPSUM STACK SYSTEM ALTERNATIVE 

LINER REQUIREMENTS 
  

 

    A.    MOSAIC BARTOW 

 

			
	      	  	 

 Appendix 1 of this Consent Decree sets forth requirements for lining Phosphogypsum Stack Systems (“Stack Systems”)
within five years of the Effective Date of this Consent Decree as a means of reducing or eliminating contamination migrating from such stacks. On January 10, 2011, Mosaic submitted a demonstration document titled “Overview of Seepage
Control Features and Projected Groundwater Quality Impacts for Mosaic Fertilizer, LLC Bartow Phosphogypsum Stack System,” hereafter referred to as the “Bartow Demonstration,” proposing that alternate means of containment can meet the
Environmental Protection Agency’s (EPA) and Florida Department of Environmental Protection’s (FDEP) environmental protection goals and obviate the requirement of Appendix 1, Attachment D, Section VII to, within five years of the Effective
Date, line existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment C, Section VI, or within five years of the Effective Date, close existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment
D. This Appendix identifies the specific Phosphogypsum Stack System components that, subject to the terms of the Consent Decree (including Paragraph 24(b) thereof), the EPA and FDEP have determined either meet the liner design standards of Appendix
1, Attachment C, Section VI, or are considered an acceptable alternative to those standards. The EPA and FDEP’s acceptance of the Bartow Demonstration for this purpose does not bind the EPA or the FDEP to the factual assertions and conclusions
of the Bartow Demonstration. This Appendix also identifies the specific Phosphogypsum Stack System components that either meet the closure design standards of Appendix 1, Attachment D, or that are considered to be an acceptable alternative to the
closure design standards of Appendix 1, Attachment D. 
 General Description 

The Bartow Phosphogypsum Stack System consists of the Closed North Phosphogypsum Stack (North Stack) and its associated system components and the Lined South
Phosphogypsum Stack Expansion (South Stack) and its associated system components (Figure 1). The following water bodies illustrated in Figure 1 are not part of the Phosphogypsum Stack System and as such are exempt from the liner requirements: Steel
Lake, Lake Vondrasek, Bonny Lake, Terry Lagoon, Clear Water Pits, Lake Greener, Lake Law, Lake Donny and Brown Lake. In addition, Mosaic has identified other water bodies existing at Bartow that are not part of the Phosphogypsum Stack System. 

The Lined DAP Pond is not associated with the North Stack System or South Stack System. It is associated with the production of monoammonium phosphate (MAP)
and diammonium phosphate (DAP) fertilizers. 

Table of Contents

 Florida Appendix 7 

 

 The North Stack-associated components include two lined auxiliary holding ponds on top of the North Stack
(Lined North Pond and Lined South Pond), a Cooling Pond System, and Area 8E South (Emergency Diversion Impoundment). The Cooling Pond System includes the R1 and R2 Return Water Channels (“R1 Canal” and “R2 Canal”) on the west
side of the North Stack, the closed Cooling Pond Area R-7 and the R-7 associated channel that runs along the north and east side of the North Stack, Area R3, Area R5, and Cooling Pond Area LR6 (Figure 2). The Cooling Pond System is used for process
water management, as well as circulation and cooling of process water, and receives incidental discharges of gypsum slurry. 
 The South Stack-associated
components include the South Stack Toe Ditches, Lined Surge Pond Area (“Area 2C”). Non-Process Wastewater ponds SR-South, SR-North and CJ-North are notable water features but they are not part of the Phosphogypsum Stack System. 

The key components of Mosaic’s Demonstration rely mostly upon soil bentonite cut-off walls (“slurry walls”) installed as engineered seepage
prevention features, and certain existing liners, as summarized below. 
 Soil Bentonite Cut-Off Walls 

Closed North Stack 
 Currently the Closed North Stack and
its Cooling Pond System have a 2  1⁄2-foot thick slurry wall that extends 35 to 75-feet into the natural ground clay confining unit beneath the Stack System to
mitigate lateral seepage from the North Stack System along the east and south walls. The slurry wall initiates at the northeast side of the North Stack and traverses the entire eastern side of the Cooling Pond System and southern end of the Cooling
Pond System, and terminates at the southwest end of the North Stack at the R1 Return Water Channel. The location of the slurry wall is designated by the green line in Figure 2. 

South Stack 
 Currently the South Stack and its associated
Lined Surge Pond and South Stack Toe Ditches has a 2  1⁄2-foot thick slurry wall that extends into the natural ground clay confining unit beneath the Stack
System to mitigate lateral seepage from the South Stack System along the north, east and south walls. The slurry wall initiates at the northwest side of the South Stack and traverses the entire northern end, eastern side and southern end of the
South Stack and terminates at the southwest end of the South Stack. The location of the slurry wall is designated by the green line in Figure 3. 

Synthetic Liners 
 Closed North Stack 

The Closed North Stack has an amended gypsum grassed cover over its side slopes and a grassed soil cover over the 40-mil HDPE liner installed within slope
runoff ditches for closure. The only two areas not covered with a soil and grass top cover are the two 80-mil HDPE-lined auxiliary holding ponds situated atop the North Stack (Figure 2).

 Florida Appendix 7 

 

 South Stack 

The South Stack has 60-mil HDPE liners installed at an interim height within the stack. The liners cover the entire portion of the stack that receive
phosphogypsum. The Lined Surge Pond at the western base of the South Stack is lined with a 80-mil HDPE liner that extends to the upstream slope of the perimeter earthen dike (Figure 3). 

Liner Requirements for Specific Components of the Stack System and for Other Water Features 

The following components or former components generally designated by red lines in Figure 4 of Mosaic Bartow’s North and South Stack Systems or
adjacent water features listed above are not subject to the lining requirements of Appendix 1, Attachments C and D, as long as they do not hereafter receive Process Wastewater or Phosphogypsum (except in emergency situations as approved by the
Florida Department of Environmental Protection). 
 1) Area 8E South (Emergency Diversion Impoundment) 

2) Inactive North Stack (including the unlined portion underlying the RO Plant Area) 

3) SR-South 
 4) SR-North 

5) CJ-North 
 The following components of Mosaic Bartow’s
North and South Stack Systems or process-water receiving ponds designated in purple in Figure 5 have existing engineered seepage control features that, as installed, either meet the liner design standards of Appendix 1, Attachment C, Section VI or
are considered by EPA and FDEP to be environmentally protective and thus considered to be an acceptable alternative to the liner design standards of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary).

 1) Lined North Pond (Inactive North Stack) 
 2) Lined
South Pond (Inactive North Stack) 
 3) South Gypsum Stack Lined Vertical Expansion (Over Unlined Stack) 

4) South Gypsum Stack Lined Surge Pond Area 
 5) Lined Cooling
Pond Area LR6 
 6) Lined DAP Pond 
 7) Lined Ditch connecting
R5 and LR6 
 8) Lined South Stack West Relief Ditch 
 9) Lined
Booster Pump Spill Containment Area 
 The following components of Mosaic Bartow’s North Stack System designated by dark blue lines in Figure 6
deviate from the Government’s liner design standards of Appendix 1, Attachment C, Section VI but are determined to be environmentally protective and thus considered to be an acceptable alternative to the requirements of Appendix 1, Attachment
C, Section VI (i.e. no additional equivalency determination necessary), subject to the Continued Monitoring Project below. All components in Mosaic Bartow’s South Stack System either do not deviate from the

 Appendix 1 of this Consent Decree sets forth requirements for lining Phosphogypsum Stack Systems (“Stack Systems”)
within five years of the Effective Date of this Consent Decree as a means of reducing or eliminating contamination migrating from such stacks. On August 16, 2010, May 27, 2011 and November 7, 2011, Mosaic submitted demonstration
documents titled “Overview of Seepage Control Features and Projected Groundwater Quality Impacts for Mosaic Fertilizer, LLC New Wales Phosphogypsum Stack System,” hereafter referred to as the “New Wales Demonstration,” proposing
that alternate means of containment can meet the EPA’s and FDEP’s environmental protection goals and obviate the requirement of Appendix 1, Attachment D, Section VII to, within five years of the Effective Date, line existing unlined
Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment C, Section VI or within five years of the Effective Date, close existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment D. This Appendix identifies
the specific Phosphogypsum Stack System components that, subject to the terms of the Consent Decree (including Paragraph 24(b) thereof), the EPA and FDEP have determined either meet the liner design standards of Appendix 1, Attachment C, Section VI
or are considered an acceptable alternative to those standards. The EPA and FDEP’s acceptance of the New Wales Demonstration for this purpose does not bind the EPA or the FDEP to the factual assertions and conclusions of the New Wales
Demonstration. This Appendix also identifies the specific Phosphogypsum Stack System components that either meet the closure design standards of Appendix 1, Attachment D or that are considered to be an acceptable alternative to the closure design
standards of Appendix 1, Attachment D. 
 General Description 

The New Wales Phosphogypsum Stack System consists of the Closed North Phosphogypsum Stack (North Stack) and its associated system components and the Lined
South Phosphogypsum Stack (South Stack) and its associated system components (Figure 1). 
 The North Stack-associated components include two lined
auxiliary holding ponds on top of the North Stack (“Lined Surge Pond (LESP)-1 and LESP-2”), a below-grade auxiliary holding pond to the southwest of the North Stack and a Cooling Pond System. The Cooling Pond System is used for process
water management, as well as circulation and cooling of Process Water, and receives incidental discharges of gypsum slurry. The Cooling Pond System consists of the main Cooling Pond, the North Channel, the East Channel, and the West Channel (Figure
2). Since closure of the North Stack, all these components (even those located on the North Stack) are now part of the operating South Stack System. Non-Process Wastewater Impoundment Area A-11 is a notable water feature used by the New Wales
Facility but is not part of the Phosphogypsum Stack System. Mosaic has identified other water bodies existing at New Wales that are not part of the Phosphogypsum Stack System.

 Florida Appendix 7 

 

 The South Stack-associated components include the Toe Ditches, comprised of the seepage collection ditch and
the decant water/runoff collection ditch, circling the South Stack, and a lined auxiliary holding pond (LESP 3) on top of the South Stack (Figure 3). 
 The
key components of the Demonstration rely mostly upon soil bentonite cut-off walls (“slurry walls”) installed as engineered seepage prevention features, and certain existing liners, as summarized below. 

Soil Bentonite Cut-Off Walls 
 Currently the Closed North
Stack and the surrounding Cooling Pond System have three 2  1⁄2-foot thick slurry walls (two of which are interconnected) that extend 70 to 115-feet into the
natural ground clay confining unit beneath the Stack System to mitigate lateral seepage from the North Stack and Cooling Pond System. The North Perimeter Dike and Plant slurry walls (which overlap and are interconnected) initiate at the northeast
side of the North Perimeter Dike and traverse the entire northern alignment of the North Stack, encompass the Plant area, and terminate midway down the western side of the North Stack. The Phase I Expansion Area slurry wall (installed to
hydraulically isolate the unlined cooling pond from the lined South Stack expansion area) initiates on the southwest end of the main Cooling Pond and West Channel and traverses the entire southern perimeter of the main Cooling Pond, and terminates
at the southeast end of the main Cooling Pond. The location of the slurry walls are designated by the green line in Figure 1. Pursuant to Appendix 6 (RCRA Project Narrative & Compliance Schedule), Mosaic has completed a slurry wall
extension project by overlapping the existing Expansion Area cut-off wall at the southwest corner of the Cooling Pond with a new slurry wall keyed 3 feet into bedclay that initiates about 900 feet east of the southeast corner of the Below Grade
Unlined Auxiliary Holding Pond (AHP) and traverses the entire south and west perimeters of the AHP, terminating at a tie-in with the existing Plant slurry wall 400 feet north of the northwest corner of the AHP. 

Synthetic Liners 
 Closed North Stack 

The Closed North Stack has an amended gypsum grassed cover over its side slopes and a grassed soil cover over the 40-mil to 60-mil high density polyethylene
(HDPE) liner installed atop the stack and mid-slope and toe drainage ditches, respectively, for closure. The only two areas not covered with a soil and grass top cover are the two 60-mil HDPE-lined auxiliary holding ponds situated atop the North
Stack (Figure 2). 
 South Stack 
 The South Stack has
60-mil HDPE liners installed over the entire base of the stack including perimeter toe ditches and upstream slope of the perimeter earthen dike (Figure 3).

does not fully conform to the liner design standards of Appendix 1, Attachment C, Section VI. EPA and FDEP anticipate that, once Mosaic implements the Northeast Sump project set forth in Appendix 6 (RCRA Project Narrative & Compliance
Schedule), it will be environmentally protective, and thus it is considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency determination necessary). 

The following components of Mosaic New Wales’s Stack System designated in purple in Figure 4 have existing engineered seepage control features that,
as installed, either meet the liner design standards of Appendix 1, Attachment C, Section VI or are determined to be environmentally protective and thus are considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C,
Section VI (i.e. no additional alternative determination necessary). 
 1) South Gypsum Stack 

2) South Gypsum Stack Toe Ditches 
 3) LESP-1 

4) LESP-2 
 5) LESP-3 on South Stack 

The following components of Mosaic’s Stack System designated in orange in Figure 5 deviate from the Government’s liner design standards of
Appendix 1, Attachment C, Section VI, but are determined to be environmentally protective, and thus are considered to be an acceptable alternative to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency

 C.   MOSAIC RIVERVIEW 

 
  

Appendix 1 of this Consent Decree sets forth requirements for lining Phosphogypsum Stack Systems (“Stack Systems”) within five years of the
Effective Date of this Consent Decree as a means of reducing or eliminating contamination migrating from such stacks. This Appendix identifies the specific Riverview Phosphogypsum Stack System components that, subject to the terms of the Consent
Decree (including Paragraph 24(b) thereof), the EPA and FDEP accept as either meeting the liner design standards of Appendix 1, Attachment C, Section VI, or being an acceptable alternative to those standards. This Appendix also identifies the
specific Riverview Phosphogypsum Stack System components that either meet the closure design standards of Appendix 1, Attachment D, or are considered to be an acceptable alternative to the closure design standards of Appendix 1, Attachment D. The
EPA and FDEP’s acceptance of Mosaic’s description of the Riverview Phosphogypsum Stack System and non-Phosphogypsum Stack System components below does not bind the EPA or the FDEP to the factual information below. 

General Description 
 The
Riverview Phosphogypsum Stack System consists of the Closed Phosphogypsum Stack (Closed Stack) and its associated system components, as well as the Northeast Phosphogypsum Stack (Northeast Stack), the Phosphogypsum Stack Expansion (Stack Expansion),
the lined cooling pond system, and associated stack system components (Figure 1). Mosaic has identified other water bodies existing at Riverview that are not part of the Phosphogypsum Stack System. 

The Closed Stack no longer receives Phosphogypsum and, therefore, is exempt from the liner requirements. The Closed Stack-associated components include a
lined auxiliary holding pond on top of the Closed Stack (Figure 1). 
 The Northeast Gypsum Stack was constructed with an 18-inch thick compacted
bottom clayey soil liner that predated the Florida Phosphogypsum Management Rule, and at the time was deemed to be adequately protective and approved by FDEP as such. The Stack is contemplated to be constructed in phases. Its current elevation is
the maximum for the existing stage, and therefore the Stack is not currently actively used for Phosphogypsum disposal. It currently is used only for Process Wastewater management. 

The lined Stack Expansion is constructed south of and extends on top of the south slope of the Northeast Stack. When the Stack Expansion reaches the crest
elevation of the Northeast Stack, the Northeast Stack top area will be lined with a 60-mil liner and the Expanded Phosphogypsum Stack (consisting of the combined Stack Expansion and lined vertical expansion atop the Northeast Stack) will be raised
to the final design elevation. 
 The Stack Expansion and Expanded Stack-associated components include a lined cooling pond system. The HDPE-clay composite
and/or HDPE/compacted gypsum inverted composite lined

cooling pond system consists of a lined Cooling Pond south of the Stack Expansion and a 32-acre cooling pond adjacent to the chemical facility. In addition, a 15-acre Lime Sludge Area with a
bottom clayey soil liner (formerly part of the cooling pond) receives seepage but is currently not actively used for process water storage and as such installation of a planned HDPE inverted composite liner in this area has been deferred. The Lime
Sludge Area will be lined with an inverted composite liner (80-mil HDPE covered with 2 feet of compacted gypsum) prior to incorporating it into a future Phosphogypsum Stack expansion and/or the Cooling Pond (Figure 1) and, in any event, within 5
years of the Effective Date. The slopes below Elevation 140 feet (NGVD) and the toe swale on the north, east and west walls of the Northeast Stack are closed. The toe swale has a grassed soil-covered 40-mil HDPE liner, and the stack slopes have a
grassed soil cover. 
 Two triangular areas located on the west side of the Stack Expansion were originally a part of the main Cooling Pond, but were later
closed and removed from the stack system watershed. 
 Soil Bentonite Cut-Off Walls 

Northeast Phosphogypsum Stack 
 The Northeast
Phosphogypsum Stack has a 2.5-foot wide slurry wall that was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below natural grade to control lateral seepage from the stack. The location of the
slurry wall is designated by the green line in Figure 1. 
 Phosphogypsum Stack Expansion 

The Phosphogypsum Stack Expansion, which was constructed mostly within the northern compartments of the former 238-acre cooling pond, is enclosed by the
2.5-foot wide slurry wall that was constructed along the perimeter dike crest of the original 238-acre cooling pond. The slurry wall was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below
natural grade. The location of the slurry wall is designated by the green line in Figure 1. 
 Cooling Pond 

The northern part of the Cooling Pond (including the Lime Sludge Area which is not currently actively used for process water storage but receives seepage from
the stack system), was constructed mostly within the southern compartments of the former 238-acre cooling pond, and is enclosed by the 2.5-foot wide slurry wall that was constructed along the perimeter dike crest of the original 238-acre cooling
pond. The slurry wall was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below natural grade. The location of the slurry wall is designated by the green line in Figure 1. 

Closed Phosphogypsum Stack 
 The Closed Phosphogypsum
Stack has a 2.5-foot wide slurry wall along its north and west boundaries that was keyed 3 feet into the underlying clayey deposit of the Hawthorn Group at typical depths of 10 to 15 feet below natural grade. The location of the slurry wall is
designated by the green line in Figure 1.

 Synthetic and Clay Liners 

Northeast Gypsum Stack 
 The Northeast Gypsum Stack, which
was constructed prior to enactment of the Phosphogypsum Management Rule in the State of Florida (i.e., Rule 62-673 Florida Administrative Code), was constructed with an 18-inch thick compacted bottom clayey soil liner installed in 6-inch lifts for
control of vertical seepage, with measured saturated hydraulic conductivities less than 1.0x10-8 cm/sec. A series of lateral drains were installed above the bottom clayey soil liner at the base of the gypsum stack along with a sand blanket drain
near the toe to collect stack seepage. A toe drain was installed during closure of the toe swale to collect all seepage in the stack seepage collection concrete sump for pumping to the cooling pond 

Phosphogypsum Stack Expansion 
 The Phosphogypsum Stack
Expansion has: (i) an inverted composite liner system at its base consisting of an 80-mil high density polyethylene (HDPE liner) and 2 feet of compacted gypsum placed over the geomembrane with a saturated hydraulic conductivity less than
1.0x10-4 cm/sec; and (ii) a 60-mil HDPE liner placed on the south slope of the Northeast Stack currently installed to an elevation of approximately 157 feet (NGVD) that will be extended upslope in phases up to the crest of the Northeast Gypsum
Stack. 
 32-Acre Cooling Pond 
 The 32-acre cooling
pond has an inverted composite liner system consisting of an 80-mil HDPE liner and 2 feet of compacted gypsum cover with a saturated hydraulic conductivity of less than 1.0x10-4 cm/sec. 

Cooling Pond 
 With the exception of an approximately
15-acre lime sludge area that has a compacted clay liner at its base, the northern portion of the cooling pond has an inverted composite liner system consisting of an 80-mil HDPE liner and 2 feet of compacted gypsum cover with a saturated hydraulic
conductivity of less than 1.0x10-4 cm/sec. The southern portion of the cooling pond has a composite liner system consisting of an 80-mil HDPE liner underlain by a 12-inch thick compacted clay liner with a saturated hydraulic conductivity of less
than 1.0x10-7 cm/sec. 
 Closed Phosphogypsum Stack 

The Closed Phosphogypsum Stack has a grassed soil cover over its side slopes and a grassed soil cover over the 40-mil HDPE liner installed atop the southern
10-acre area of the stack top grade. The only area atop the stack not covered with soil and grass is the 80-mil HDPE-lined auxiliary holding pond situated atop the Closed Phosphogypsum Stack (Figure 1). 

Lined Floating Ditch 
 The “Lined Floating
Ditch” connecting the chemical plant to the lined 32-acre cooling pond was lined by Mosaic in 2011 (pursuant to a plan approved by FDEP) with an 80-mil HDPE liner and completely covered with 6-inch concrete fabriform. The HDPE liner was tied
into the 32-acre cooling pond liner (Figure 1).

Supplemental Environmental Project Description 

As the Supplemental Environmental Project (SEP) required under Paragraph 39 of this Consent Decree, Mosaic shall implement the following project to mitigate
and prevent certain potential environmental impacts associated with seepage emanating from areas abutting closed components of the Phosphogypsum Stack System at the facility formerly owned and operated by Mulberry Phosphates Inc., located in
Mulberry, Florida (the “Mulberry Facility”). 
 Mosaic’s performance and satisfactory completion of this project shall be as determined based
on inspection and project oversight to be provided by the Florida Department of Environmental Protection (Department). Based on the Department’s review of options for eliminating or preventing the seepage emanation discussed herein, the
Department believes the value of this SEP to the State of Florida is in excess of $1,200,000. Mosaic has previously voluntarily agreed, pursuant to Department Contract No. EXC005, to undertake closure activities on behalf of the Department at the
Mulberry Facility. The project described herein is not addressed by existing contracts or agreements between Mosaic and the Department. 

I.    Project Description: 

Following closure of the South Cooling Pond (“SCP”) of the Mulberry Phosphogypsum Stack System, rainfall infiltration in an abutting parcel of land
caused lateral seepage of historically contaminated ground water to rise and emanate from the ground surface in a location just east of the at the northeast corner of the closed SCP. Such contaminated ground water, once emanating at the ground
surface, would no longer be captured by the buried collection drains constructed for closure of the Mulberry Facility, resulting in an otherwise preventable source of nutrients and other surface water pollutants in the Alafia River and Tampa Bay
watersheds. In order to mitigate and prevent potential contamination of surface water runoff that would otherwise be discharged through the Mulberry Facility’s NPDES permitted outfall, the following tasks will be performed by Mosaic: 

 

	 	1.	Perform engineering services (and related permitting, administrative, and other tasks) for site investigations, basic and detailed design, construction QA/QC, construction inspection, and certification of the completed
works 

	 	2.	Provide engineering staff to perform onsite project construction management. 

	 	3.	Following the Department’s approval of the basic and detailed designs under this SEP, Mosaic shall then commence construction activities under this SEP as follows: 

	 	a.	Install an additional underdrain system, including a seepage conveyance system to intercept and collect impacted seepage that would otherwise emanate from the ground surface as described above. 

	 	b.	Provide earthen fill and re-grade the impacted construction area to meet the corresponding approved design grade. 

	 	c.	Install an HDPE liner and protective cover at the northeast corner of the SCP, to design grade, that would be tied into the existing SCP HDPE liner, to control infiltration in this area. 

	 	d.	Perform limited cut/fill in the adjacent area to match the design grade, promote positive drainage of stormwater away from the SCP and minimize rainfall infiltration that would affect groundwater levels and otherwise
contribute to the referenced groundwater seepage. 

	 	4.	Perform hydraulic calculations and reconfigure (if needed in accordance with the detailed design) Outfall 001F, and the associated conveyance structure to meet design flow requirements. 

Table of Contents

	 	5.	Re-grass and provide maintenance as may be needed to establish a stabilized vegetative cover for the disturbed project construction area, for a minimum of nine months from the end of the associated construction
activities. 

 II.  Environmental Benefit: 

Completion of the above tasks are expected to mitigate and prevent future contamination to surface water runoff with nutrients and other contaminants that
would otherwise cause pollutions of stormwater runoff within the Alafia River and Tampa Bay contributing watersheds. 
 III. Performance Schedule:

 Within 90 days from the Effective Date of this Consent Decree, Mosaic will finalize a work plan and schedule to implement the project outlined
above for the Department’s review and approval. Such schedule shall include a milestone for the Department’s separate approval of detailed design plans, prior to Mosaic’s commencement of installation for the additional underdrain
system under this SEP. Such schedule shall provide for the completion of the tasks in Section I.1 - I.4 within 1.5 years of the Effective Date of this Consent Decree. 

Following the Department’s approval of such final work plan, Mosaic shall implement the work plan in accordance with the design, associated
specifications, and the schedule incorporated therein. Any changes required to the work plan, or its implementation schedule shall be agreed upon by Mosaic and the Department. Within 90 Days of completion of the tasks in Section I.1 - I.4, Mosaic
will provide the Department with as-built construction drawings and a Certification of Construction Completion for the works under this SEP.

 CONSENT DECREE

 WHEREAS, Plaintiffs, the United States of America (United States), on behalf of the United States Environmental Protection
Agency (EPA), and the Louisiana Department of Environmental Quality (LDEQ), an agency of the State of Louisiana to which the Louisiana Legislature has delegated the power and duty to enforce the Louisiana Environmental Quality Act (EQA) and
Louisiana Environmental Quality Regulations, including the authority to bring actions in courts of competent jurisdiction for violations of the EQA (La. R.S. 30:2001 et seq.) and Louisiana’s Hazardous Waste Regulations (LAC 33: V. Subpart 1),
(together the Plaintiffs), have filed a complaint alleging that Defendant, Mosaic Fertilizer, LLC (Mosaic) has violated the Resource Conservation and Recovery Act (RCRA), 42 United States Code (U.S.C.) § 6901 et seq., La. R.S. 30:2001 et
seq, and the applicable regulations in 40 C.F.R. Parts 260-270, and LAC 33:V.Subpart 1, at its sulfuric acid, phosphoric acid and fertilizer manufacturing facilities located in Uncle Sam and Saint James, Louisiana, respectively the Uncle Sam
Facility and the Faustina Facility (collectively the Facilities); 
 WHEREAS, the Complaint includes allegations that Mosaic failed
to characterize and illegally treated, stored and disposed of hazardous waste from various processes at its Facilities, including: the production of sulfuric acid, diammonium phosphate (DAP) and monoammonium phosphate (MAP) fertilizer, and
fluorosilicic acid (FSA); wastes generated during cleaning of the phosphoric acid plant and fertilizer plant equipment; and wastewaters generated from the scrubbers used to control air pollution from the phosphoric acid plants and from other
chemical and waste management processes at its Facilities without a RCRA permit or interim status. The Complaint also alleges that Mosaic illegally placed hazardous wastes in the Uncle Sam Phosphogypsum Stack System dedicated for managing phosphoric
acid production wastes

Consent Decree and any such action and over Mosaic and The Mosaic Company, and further consent to venue in this judicial district. 

2.        Pursuant to Section 3008(a)(2) of RCRA, 42 U.S.C. § 6928(a)(2), notice of the
commencement of this action has been given to LDEQ. 
 3.        For purposes of this Consent Decree
only, Mosaic agrees that the Complaint states claims upon which relief may be granted pursuant to Sections 3004 and 3005 of RCRA, 42 U.S.C. §§ 6924 and 6925, and La. R.S. 30:2001 et seq. 

II.  APPLICABILITY 

4.        The obligations of this Consent Decree apply to and are binding upon the United States,
LDEQ, Mosaic, and, as provided herein, The Mosaic Company, and any successors, assigns, or other entities or persons otherwise bound by law. Rights granted to EPA under this Consent Decree may be exercised by LDEQ upon the written agreement of EPA
and LDEQ with notice to Mosaic. Nothing in this Consent Decree shall apply to administrative or enforcement proceedings other than this action or an action to enforce this Consent Decree. Nor does anything in this Consent Decree relieve Mosaic of
its obligation to comply with any federal and state laws applicable to activities that are not within the definition of Work in this Consent Decree. 

5.        No transfer of ownership or operation of all or a portion of a Facility, whether in
compliance with the procedures of this Paragraph or otherwise, shall relieve Mosaic of its obligation to ensure that the terms of this Consent Decree are implemented, unless: (1) the transferee agrees in writing to undertake the obligations
required by this Consent Decree and to be substituted for Mosaic as a Party to the Consent Decree and thus be bound by the terms thereof; and (2) the United States, after consultation with LDEQ, consents in writing to relieve Mosaic and the
Mosaic Company of their respective obligations under this Consent Decree

pursuant to Section XVIII (Modification) of this Consent Decree. At least thirty (30) Days prior to a proposed transfer of Mosaic’s obligations under this Consent Decree, or such other
period agreed to by the Parties in writing: (i) Mosaic shall provide a copy of this Consent Decree to the proposed transferee, if not previously provided; and (ii) shall provide written notice of the prospective transfer, together with a
copy of the proposed written agreement (subject to Paragraphs 82 and 83 of this Consent Decree and as may otherwise be agreed in writing) transferring obligations to the transferee, to EPA, LDEQ, the United States Attorney for the Eastern District
of Louisiana, and the United States Department of Justice, in accordance with Section XV (Notices) of this Consent Decree, together with a request for approval. The United States’ decision whether to approve the transferee’s substitution
for Mosaic under this Consent Decree, and what conditions may attend approval, will take into account: (i) the status of the projects in Appendix 6 (RCRA Compliance Schedule), (ii) whether the transferee has or will have prior to the
transfer the financial and technical capability to comply with this Consent Decree, (iii) and other factors that may be deemed relevant, including but not limited to the environmental compliance history of the proposed transferee and the
environmental management capabilities of the proposed transferee. As set forth in Appendix 2, Paragraph 36, any such transfer will not include the Financial Assurance obligations specified for Mosaic therein, and therefore will include Financial
Assurance conditions appropriate to the transferee. Any transfer of ownership or operation of all or a portion of the Facilities without complying with this Paragraph constitutes a violation of this Consent Decree. The United States’ refusal to
approve, or approval with conditions for, the substitution of the transferee for Mosaic under this Consent Decree shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of this Consent Decree, but any judicial review
shall be conducted pursuant to Paragraph 76(a) of this

 32.        Correction of Non-Compliance at the
Uncle Sam Facility. 
 (a)        If Mosaic determines, with or without notice from EPA and/or
LDEQ, that it is violating, or will violate, any requirement of Section V (Compliance Requirements) of this Consent Decree, other than those set forth in Paragraphs 15(f) (temporary storage of First Saleable Product) and 25 (Financial Assurance
obligations governed by Appendix 2 (Financial Assurance)), Mosaic shall submit with its report of the violation, pursuant to Section VIII (Reporting Requirements) of this Consent Decree, and shall subsequently implement, a Correction Plan to rectify
the violation, if it has not already corrected the violation by the time of the report. The Correction Plan shall include a schedule for correcting the violation. 

(b)  In the event of a violation subject to Paragraph 32(a), Mosaic shall be considered to be in compliance with this Consent Decree
for purposes of: (1) continuing to manage wastes that Paragraphs 15 through 18 allow to be input to Upstream Operations or Downstream Operations or managed in BHT Recovery Units or together with Bevill-Exempt Wastes; and (2) assessing
Mosaic’s compliance with this Consent Decree under Paragraphs 34, 85, 86 and 87 of this Consent Decree, provided that: 

(1)     Mosaic deposits wastes governed by Paragraphs 15-18 only in a Phosphogypsum Stack System
subject to the Stack System Requirements set forth in Paragraph 15(a); and 
 (2)     Mosaic: 

(i).      Timely implements and completes its Correction Plan; or 

(ii).     Refers an allegation of non-compliance with Section V (Work Requirements) or with a Correction Plan to
dispute resolution pursuant to Section XI (Dispute Resolution) and either 

   a.        Prevails in the dispute resolution or

 b.        Satisfactorily complies with an EPA or
judicial directive to correct any instances of non-compliance 
 (collectively, Continuing Compliance Criteria). Nothing in this Paragraph shall be
construed as EPA approval of Mosaic’s correction efforts pursuant to this Paragraph, as a waiver of stipulated penalties for the violation pursuant to Section IX (Stipulated Penalties), or as limiting the rights reserved by Plaintiffs under
Section VI (Work Takeover) or Paragraph 88 of this Consent Decree. EPA reserves the right to require, upon written request that a Correction Plan be submitted to EPA for approval in accordance with Paragraphs 27 - 31, above. Mosaic’s compliance
with this Paragraph is without prejudice to its rights under Section X (Force Majeure) and Section XI (Dispute Resolution) of this Consent Decree. 

33.        Permits. Where any compliance obligation under this Section requires Mosaic to
obtain a federal, Louisiana, or local permit, or other form of approval, Mosaic shall submit timely and complete applications and take such actions as are necessary to obtain all such permits or approvals. A request for supplementation by the
permitting agency does not constitute a notice or finding that an application was incomplete for the purpose of this Paragraph unless the permitting agency determines that the original application was so deficient as to constitute a material breach
of Mosaic’s obligations under this Consent Decree. Mosaic may seek relief under the provisions of Section X (Force Majeure) of this Consent Decree for any delay in the performance of any such obligation resulting from a failure to obtain, or a
delay in obtaining, any permit or approval required to fulfill such obligation, if Mosaic has submitted timely and complete applications and has taken such actions as are necessary to timely obtain all such permits or approvals.

 34.        Provided that Mosaic remains in compliance
with Section V (Compliance Requirements) or the Continuing Compliance Criteria set forth in Paragraph 32 at the Uncle Sam Facility, that Facility shall not be required to operate as a Treatment Storage and Disposal Facility pursuant to
Section 3005 of RCRA and its implementing federal and/or Louisiana regulations, with respect to: 

           (a) the treatment, storage, transport, management, and
disposal of Bevill-Exempt 
 Wastes that have been commingled with hazardous wastes or otherwise managed in violation of law as alleged in
the Complaint, 

                     
 (i) prior to the lodging of this Consent Decree, 

                     
 (ii) prior to completing the compliance projects set forth in Appendix 6 (RCRA Project Narrative and Compliance Schedule) as provided by Paragraph 13, or 

                     
 (iii) during timely implementation of a Correction Plan as set forth in Paragraph 32; and 

             (b) wastes that Paragraphs 15 through 18 allow to be input
to Upstream Operations or Downstream Operations or managed in BHT Recovery Units or together with Bevill-Exempt Wastes. 
  

VI.  WORK TAKEOVER 

35.        In the event EPA determines that Mosaic has: (a) ceased implementation of any portion
of the Work; or (b) is seriously or repeatedly deficient or late in its performance of the Work; or (c) is implementing the Work in a manner that may cause an endangerment to human health or the environment, EPA, after consultation with
LDEQ and with the joint approval of the EPA Region 6 Regional Administrator and the Assistant Administrator for the EPA Office of Enforcement and Compliance Assurance, may issue a written notice (Work Takeover Notice) to 

  
 42 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 Mosaic. Any Work Takeover Notice issued by EPA shall specify the grounds upon which such notice was issued
and shall provide Mosaic a period of thirty (30) Days within which to remedy the circumstances giving rise to EPA’s issuance of such notice. 

36.        If, after expiration of the thirty (30) Day period specified in Paragraph 35 of this
Section, the Work Takeover Notice has not been withdrawn by EPA and Mosaic has not remedied to EPA’s satisfaction the circumstances giving rise to EPA’s issuance of the Work Takeover Notice, EPA at any time thereafter may undertake Work
Takeover by: (a) assuming and/or directing the performance of; (b) seeking the appointment of a receiver to direct the performance of; or (c) accessing Financial Assurance (with the concurrence of LDEQ) to finance the performance of
all or any portions of the Work that EPA deems necessary to correct the violations or conditions that triggered the Work Takeover Notice pursuant to Paragraph 35 (Work Takeover). EPA shall notify Mosaic in writing (which writing may be electronic)
if EPA determines that implementation of a Work Takeover is warranted under this Section of the Consent Decree. In the event that EPA seeks to appoint a receiver to direct the performance of the Work, Mosaic shall not oppose such appointment on
grounds other than lack of competence or conflict of interest, but shall retain its right to challenge the underlying Work Takeover in Dispute Resolution, as set forth in the following Paragraph and Section XI (Dispute Resolution) of this Consent
Decree. In implementing any Work Takeover, EPA shall make reasonable efforts not to interfere with Facility operations not directly affected by the conditions that triggered the Work Takeover. 

37.        In the event that Mosaic invokes Section XI (Dispute Resolution) of this Consent Decree
with respect to EPA’s Work Takeover and/or its selection of options set forth in Paragraph 36 (which must be disputed together with the underlying Work Takeover and pursuant 

  
 43 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
to Paragraph 76(a) of this Consent Decree), EPA during the pendency of any such dispute may, in its unreviewable discretion, commence and continue a Work Takeover until the earlier of:
(a) the date that Mosaic remedies, to EPA’s satisfaction, the circumstances giving rise to issuance of the Work Takeover Notice; or (b) the date that a final decision is rendered in accordance with Section XI (Dispute Resolution) of
the Consent Decree requiring EPA to terminate such Work Takeover. 
 38.        After commencement
and for the duration of any Work Takeover, EPA or any appointed receiver shall have immediate access to and benefit of any Financial Assurance provided pursuant to Paragraph 25 of this Consent Decree and Appendix 2 to implement the Work. If EPA
or any appointed receiver are unable to access the Financial Assurance, or the Work addressed by the Work Takeover is not covered by Financial Assurance, then any unreimbursed costs incurred by EPA in connection with the Work Takeover shall be
considered a financial obligation owed by Mosaic to the United States and collectible in an action to enforce this Consent Decree. Nothing in this Paragraph shall be construed to relieve Mosaic of its obligation to provide adequate Financial
Assurance pursuant to Appendix 2. In the event that it is determined in Dispute Resolution that the Work Takeover was not warranted, any unexpended funds in a Stand-by Trust that originated from a letter of credit, surety bond or corporate guarantee
shall be used to restore any pre-existing Trust Fund to the pre-Work Takeover level, if necessary, and any balance of unexpended funds shall be released and used to re-establish the original financial mechanism(s). 

VII.  BENEFICIAL ENVIRONMENTAL PROJECTS 

39.        Within thirty (30) Days after the Effective Date of the Consent Decree, Mosaic shall
deposit $1,000,000.00 into an escrow account established and administered by LDEQ, in 

  
 44 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
accordance with instructions that will be provided by LDEQ within sixty (60) Days of the lodging of this Consent Decree, for the purpose of LDEQ’s conducting the beneficial
environmental projects (BEPs) identified in this Section. After January 1, 2020, any funds that remain in this escrow account and that have not been committed to the BEPs identified in this Section will be transferred by LDEQ to the Louisiana
Hazardous Waste Clean-Up Fund. 
 40.        Minerals Toxicity Study and Mineral Criteria
Assessment BEP. LDEQ will assess statewide water quality criteria/standards for minerals (e.g., chlorides, sulfates) based upon a thorough review of scientific literature, data from aquatic toxicity tests, and a review of criteria/standards from
other states and jurisdictions. BEP funding will be utilized in conducting aquatic toxicity testing that will be utilized in establishing a statewide formula for the development of mineral criteria and/or standards protective of waters of the State.
The results of these studies will provide data that may be used by Louisiana to help develop or refine state mineral related standards. 

41.        Minerals Toxicity Study and Mineral Criteria Assessment BEP Objectives. The
objectives for the BEP referenced in Paragraph 40 are to: (1) Develop a study, including acute and chronic toxicity tests, on representative Louisiana species across a range of hardness values (including low hardness waters) typical of
Louisiana; and (2) Conduct toxicity studies to determine acute and chronic effects to calculate ratios and/or genus mean acute values that can be used to help develop State standards for chlorides, sulfates, and/or other appropriate minerals
criteria. 
 42.        Producer-Specific Watershed Nutrient Management Plans BEP. LDEQ, in
coordination with the Louisiana State University Agricultural Center, will develop producer-specific master programs and Watershed Nutrient Management Plans (collectively WNMP) to be 

  
 45 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
utilized by beef cattle, dairy, and poultry producers for the purpose of reducing pollution, such as excess nutrients, into the environment through improved farm practices specific to producer
needs. These WNMPs will enhance the Comprehensive Nutrient Management Plans that are available from the United States Department of Agriculture (USDA) by incorporating complementary activities for nutrient management, such as operation and
maintenance, tracking, monitoring, and beneficial use. 
 43.        Producer-Specific Watershed
Nutrient Management Plans BEP Objectives. The objectives for the BEP referenced in Paragraph 42 are to: (1) Develop WNMPs to address nutrients, potentially including the completion of an environmental needs assessment to identify the water
quality issues for a watershed; and (2) Develop WNMPs for the identified producer-specific commodities in targeted watersheds. 

44.        Mosaic’s funding of the escrow account shall not be construed as an endorsement of,
and Mosaic reserves all rights to dispute, any methodologies, analyses, conclusions or findings resulting from the BEPs described above. 

45.        If Defendant fails to deposit funds in the escrow account in accordance with Paragraph 39,
stipulated penalties may be assessed under Section IX (Stipulated Penalties). 
 VIII.  REPORTING REQUIREMENTS 

46.        If Mosaic determines that it has violated or will violate, any requirement of this Consent
Decree, Mosaic shall notify EPA and LDEQ of such violation and its likely duration, in writing (unless otherwise directed by EPA or LDEQ), within twelve (12) Days of the date Mosaic first becomes aware of the violation, with an explanation of
the likely cause of the violation and of the remedial steps taken, or to be taken, to prevent or minimize such violation. If the cause of a violation cannot be fully explained at the time the report is due, Mosaic shall so

state in the report. Mosaic shall investigate the cause of the violation and shall then submit an amendment to the report, including a full explanation of any identifiable cause(s) of the
violation, within thirty (30) Days of the date Mosaic becomes aware of the violation. Nothing in this Paragraph or Paragraphs 47 and 48 relieves Mosaic of its obligation to provide the notice required by Section X of this Consent Decree (Force
Majeure). 
 47.        Periodic Reporting 

(a)        Uncle Sam. Within forty-five (45) Days after the end of each calendar-quarter

minimize such violation; and (i) any notification or reporting pursuant to 40 CFR 265.196(d) or LAC 33:V.1913.D, as set forth in Project 6 in Appendix 6 (RCRA Narrative and Compliance
Schedule) for the Faustina Facility. Thereafter, Mosaic shall submit such reports annually until this Consent Decree is terminated with respect to the Faustina Facility. 

48.        Whenever any violation of this Consent Decree, or any other event affecting Mosaic’s
performance under this Consent Decree or the performance of its Facility, may pose an immediate threat to the public health or welfare or the environment, Mosaic shall, unless otherwise directed, notify EPA and LDEQ in Section XV (Notices) orally or
by electronic or facsimile transmission as soon as possible, but no later than twenty-four (24) hours after Mosaic first knew of the event, and shall comply with the requirements of Appendix 1, Attachment E (Imminent and Substantial
Endangerment Diagnostic Requirements). Any violation of this notice requirement shall be deemed to terminate on the Day that both Plaintiffs have received actual notice of the violation or event from Mosaic or by other means. This notice requirement
does not relieve Mosaic of its obligation to comply with any federal and state laws applicable to the violation or event. This notice requirement is in addition to the requirement to provide notice of a violation of this Consent Decree set forth in
the preceding Paragraph. 
 49.        All reports shall be submitted to the persons designated to
receive Notices for Plaintiffs in Section XV (Notices) of this Consent Decree. All notices and submittals to “EPA and/or LDEQ” under this Consent Decree (including Appendices), other than those required by this Section or that are
submitted for approval pursuant to Paragraphs 27-31, may be submitted to LDEQ only, provided that a copy of the cover letter identifying the notice or submittal is also sent to EPA. Mosaic also shall supply EPA with a copy of such notice(s) or
submittal(s) upon request by EPA.

Section shall be signed by a responsible corporate official of Mosaic (as defined in 40 C.F.R. § 270.11(a)) and shall include the following certification: 

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a
system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the

violations. 
 This certification requirement does not apply to emergency notifications where compliance would be impractical. 

51.        The reporting requirements of this Consent Decree do not relieve Mosaic of any reporting
obligations required by the RCRA Requirements, or by any other federal, Louisiana, or local law, regulation, permit, or other requirement. However, the reporting requirements of this Consent Decree shall not require Mosaic to re-submit any report,
plan or information submitted by Mosaic to EPA and/or LDEQ prior to the Effective Date of this Consent Decree. 

52.        Any information provided pursuant to this Consent Decree may be used by the Plaintiffs in
any proceeding to enforce the provisions of this Consent Decree and as otherwise permitted by law.

(12) Days of a written demand by either Plaintiff, subject to its right to invoke dispute resolution in accordance with Section XI (Dispute Resolution). Except as provided in Paragraph 45, Mosaic shall pay fifty percent (50%) of the total
stipulated penalty amount due to the United States and fifty percent (50%) to LDEQ. The Plaintiff making a demand for payment of a stipulated penalty shall simultaneously send a copy of the demand to the other Plaintiff. 

59.        Each Plaintiff, may, in the unreviewable exercise of its discretion, reduce or waive
stipulated penalties otherwise due to it under this Consent Decree. The determination by 

  
 52 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
one Plaintiff not to seek stipulated penalties, or to subsequently waive or reduce the amount it seeks, shall not preclude the other Plaintiff from seeking the full amount of the stipulated
penalties owed. 
 60.        Stipulated penalties shall continue to accrue as provided in Paragraph
57, during any Dispute Resolution, but need not be paid until the following: 
 (a)        If the
dispute is resolved by agreement or by a decision of the United States or LDEQ that is not subject to judicial review or appealed to the Court, Mosaic shall pay accrued penalties determined to be owing, together with Interest, to the United States
or LDEQ within thirty (30) Days of the effective date of the agreement or the receipt of the United States’ or LDEQ’s decision or order. 

(b)        If the dispute is appealed to the Court and the United States or LDEQ prevails in whole or
in part, Mosaic shall pay all accrued penalties determined by the Court to be owing, together with Interest, within sixty (60) Days of receiving the final Court decision. 

61.        Mosaic shall pay stipulated penalties owing to the United States in the manner set forth
and with the confirmation notices required by Paragraph 10, except that the transmittal letter shall state that the payment is for stipulated penalties and shall state for which violation(s) the penalties are being paid. Mosaic shall pay stipulated
penalties owing to LDEQ in accordance with Paragraph 11, except that the transmittal letter shall state that the payment is for stipulated penalties and shall state for which violation(s) the penalties are being paid. 

62.        Mosaic shall not deduct stipulated penalties paid under this Section in calculating its
Louisiana and federal income tax. 
 63.        If Mosaic fails to pay stipulated penalties
according to the terms of this Consent Decree, Mosaic shall be liable for Interest on such penalties, as provided for in 28 U.S.C. § 1961, 

  
 53 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
accruing as of the date payment became due. Nothing in this Paragraph shall be construed to limit the United States or LDEQ from seeking any remedy otherwise provided by law for Mosaic’s
failure to pay any stipulated penalties. 
 64.        Subject to the provisions of Section XIII
(Effect of Settlement/ Reservation of Rights) of this Consent Decree, the stipulated penalties provided for in this Consent Decree shall be in addition to any other rights, remedies, or sanctions available to the United States or LDEQ for
Mosaic’s violation of this Consent Decree or applicable law. Where a violation of this Consent Decree is also a violation of relevant statutory or regulatory requirements, Mosaic shall be allowed a credit for any stipulated penalties paid
against any statutory penalties imposed for such violation. 
 X. FORCE MAJEURE 

65.        Force majeure, for purposes of this Consent Decree, is defined as any event arising from
causes beyond the control of Mosaic, of any entity controlled by Mosaic, or of Mosaic’s contractors that delays or prevents the performance of any obligation under this Consent Decree despite Mosaic’s best efforts to fulfill the
obligation. The requirement that Mosaic exercise best efforts to fulfill the obligation includes using best efforts to anticipate any potential force majeure and best efforts to address the effects of any potential force majeure (1) as it is
occurring and (2) following the potential force majeure such that the delay and any adverse effects of the delay are minimized to the greatest extent possible. Force majeure does not include Mosaic’s financial inability to perform any
obligation under this Consent Decree. 
 66.        If any event occurs or has occurred that may
delay the performance of any obligation under this Consent Decree, whether or not caused by a force majeure event, Mosaic shall provide notice orally or by electronic or facsimile transmission as soon as possible, as

  
 54 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
provided in Section XV (Notices) of this Consent Decree, but not later than seven (7) Days after the time when Mosaic first knew that the event might cause a delay. Within ten (10) Days
thereafter, Mosaic shall provide written notice to EPA and LDEQ with an explanation and description of the reasons for the delay; the anticipated duration of the delay; all actions taken or to be taken to prevent or minimize the delay; a schedule
for implementation of any measures to be taken to prevent or mitigate the delay or the effect of the delay; Mosaic’s rationale for attributing such delay to a force majeure event if it intends to assert such a claim; and a statement as to
whether, in the opinion of Mosaic, such event may cause or contribute to an endangerment to public health, welfare or the environment. Mosaic shall include with any notice all available documentation supporting a claim that the delay was
attributable to a force majeure event. Mosaic shall be deemed to know of any circumstance of which Mosaic, any entity controlled by Mosaic, or Mosaic’s contractors knew or reasonably should have known. Failure to comply with the above
requirements regarding an event shall preclude Mosaic from asserting any claim of force majeure regarding that event, provided, however, that if EPA, despite the late notice, is able to assess to its satisfaction whether the event is a force majeure
under Paragraph 65 and whether Mosaic has exercised its best efforts under Paragraph 65, EPA may, in its unreviewable discretion, excuse in writing Mosaic’s failure to submit timely notices under this Paragraph. 

67.        If EPA, after consultation with LDEQ, agrees that the delay or anticipated delay is
attributable to a force majeure event, the time for performance of the obligations under this Consent Decree that are affected by the force majeure event will be extended by EPA, after consultation with LDEQ, for such time as is necessary to
complete those obligations. An extension of the time for performance of the obligations affected by the force majeure event shall not, of itself, extend the time for performance of any other obligation. If EPA, after consultation

  
 55 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
with LDEQ, agrees that the delay is attributable to a force majeure event, EPA will notify Mosaic in writing of the length of the extension, if any, for performance of the obligations affected by
the force majeure event. 
 68.        If EPA, after consultation with LDEQ does not agree that the
delay or anticipated delay has been or will be caused by a force majeure event, EPA will notify Mosaic in writing of its decision. 

69.        If Mosaic elects to invoke the dispute resolution procedures set forth in Section XI
(Dispute Resolution), it shall do so no later than fifteen (15) Days after receipt of EPA’s notice. In any such proceeding, Mosaic shall have the burden of demonstrating by a preponderance of the evidence that the delay or anticipated
delay has been or will be caused by a force majeure event, that the duration of the delay or the extension sought was or will be warranted under the circumstances, that best efforts were exercised to avoid and mitigate the effects of the delay, and
that Mosaic complied with the requirements of Paragraphs 65 and 66, above. If Mosaic carries this burden, the delay at issue shall not constitute a violation by Mosaic of the affected obligation of this Consent Decree identified to EPA and the
Court. 
 XI.  DISPUTE RESOLUTION 

70.        Unless otherwise expressly provided for in this Consent Decree, the dispute resolution
procedures of this Section shall be the exclusive mechanism to resolve all disputes arising under or with respect to this Consent Decree. Mosaic’s failure to seek resolution of a disputed issue under this Section shall preclude Mosaic from
raising any such issue as a defense to an action by the United States or LDEQ to enforce any obligation of Mosaic arising under this Consent Decree. 
  

  
 56 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 71.        Informal Dispute Resolution. Any
dispute subject to Dispute Resolution under this Consent Decree shall first be the subject of informal negotiations, which may include any third-party assisted, non-binding alternative dispute resolution process agreeable to the Parties. Mosaic
shall submit a written Notice of Dispute to both the United States and LDEQ within thirty (30) Days after receiving written notice from EPA of a decision that Mosaic disputes. The dispute shall be considered to have arisen on the later of the
dates that the United States or LDEQ receives a written Notice of Dispute. Such Notice of Dispute shall state clearly the matter in dispute. The period of informal negotiations shall not exceed twenty (20) Days from the date that the dispute
arises, unless that period is modified by written agreement between the United States and Mosaic. If the Parties cannot resolve a dispute by informal negotiations, then the position of EPA, after consultation with LDEQ, shall be considered binding,
unless Mosaic invokes formal dispute resolution procedures as provided in the following Paragraph. 

72.        Formal Dispute Resolution. If Mosaic elects to invoke formal dispute resolution,
Mosaic shall, within thirty (30) Days after the conclusion of the informal negotiation period, submit to EPA and LDEQ a written Statement of Position regarding the matter in dispute. The Statement of Position shall include, but need not be
limited to, any factual data, analysis, or opinion supporting Mosaic’s position and any supporting documentation relied upon by Mosaic. 

73.        EPA, after consultation with LDEQ, shall submit its Statement of Position within forty-five
(45) Days of receipt of Mosaic’s Statement of Position. The EPA Statement of Position shall include or clearly reference, but need not be limited to, any factual data, analysis, or opinion supporting that position and any supporting
documentation relied upon by EPA. Where appropriate, EPA may allow submission of supplemental statements of position by the 

  
 57 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
Parties to the dispute. The EPA Statement of Position shall be binding on Mosaic unless Mosaic files a motion for judicial review of the dispute in accordance with the following Paragraph. 

74.        Unless expressly stated otherwise in this Consent Decree, Mosaic may seek judicial review
of the dispute by filing with the Court and serving on the United States and LDEQ, in accordance with Section XV (Notices) of this Consent Decree, a motion requesting judicial resolution of the dispute. The motion must be filed within thirty
(30) Days of receipt of the EPA Statement of Position pursuant to the preceding Paragraph. The motion shall contain a written statement of Mosaic’s position on the matter in dispute, including any supporting factual data, analysis,
opinion, or documentation, and shall set forth the relief requested and any schedule within which the dispute must be resolved for orderly implementation of the Consent Decree. 

75.        The United States, after consultation with LDEQ, shall respond to Mosaic’s motion
within the time period allowed by the Local Rules of this Court. Mosaic may file a reply memorandum, to the extent permitted by the Local Rules. 

76.        Standard of Review 

 (a)        Disputes Concerning Matters Accorded Record Review. In any dispute brought
under this Section pertaining to the adequacy or appropriateness of plans, procedures to implement plans, schedules or any other items requiring approval by EPA under this Consent Decree; the adequacy of the Work performed pursuant to this Consent
Decree; and all other disputes that are accorded review on the administrative record under applicable principles of administrative law, EPA shall compile an administrative record of the dispute containing all Statements of Position, including
supporting documentation and referenced data or information, 

  
 58 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
and Mosaic shall have the burden of demonstrating, based on the administrative record, that the position of the United States is arbitrary and capricious or otherwise not in accordance with law.

 (b)    In any other dispute brought under this Section, Mosaic shall bear the burden of demonstrating that its
position complies with and furthers the objectives of this Consent Decree. 
 77.        The
invocation of dispute resolution procedures under this Section shall not, by itself, extend, postpone, or affect in any way any obligation of Mosaic under this Consent Decree, unless and until final resolution of the dispute so provides or unless
ordered by the Court. Stipulated penalties with respect to the disputed matter shall continue to accrue from the first Day of noncompliance, but payment shall be stayed pending resolution of the dispute as provided in Paragraph 72. If Mosaic does
not prevail on the disputed issue, stipulated penalties shall be assessed and paid as provided in Section IX (Stipulated Penalties). 

XII. INFORMATION COLLECTION AND RETENTION 

78.        The United States, LDEQ, and their representatives, including attorneys, contractors, and
consultants, shall have the right of entry into any of Mosaic’s Louisiana Facilities, at all reasonable times, upon presentation of appropriate identification, to: 

 (a)  monitor the progress of activities required under this Consent Decree; 

 (b) verify any data or information submitted to the United States or LDEQ in accordance with the terms of this Consent Decree; 

 (c)  obtain samples and, upon request, splits of any samples taken by Mosaic or its representatives, contractors, or
consultants; 
  (d)  obtain documentary evidence, including photographs and similar data; 

 (e)  assess Mosaic’s compliance with this Consent Decree; and 

  
 59 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

  (f)  conduct, direct or review Work pursuant to Section VI (Work Takeover)
of this Consent Decree. 
 79.        Upon request, Mosaic shall provide EPA, LDEQ and their
authorized representatives splits of any samples taken by Mosaic. Upon request, EPA and LDEQ shall provide Mosaic splits of any samples taken by EPA, LDEQ, and their authorized representatives. 

80.        Mosaic shall retain, and shall require its contractors and agents to preserve, all
non-identical copies of all documents, records, or other information (including documents, records, emails or other information in electronic form and including any documents, records, data or other information underlying the submission of any
Report required pursuant to Section VIII (Reporting Requirements)) in its or its contractors or agents possession or control, or that come into its or its contractors’ or agents’ possession or control and that relate to Mosaic’s
performance of its obligations under this Consent Decree or adherence to the requirements associated with the management of waste materials allowed under Paragraphs 15 through 18 for a period of five (5) years after the creation of such
documents, records or other information. This information-retention requirement shall apply regardless of any contrary corporate or institutional policies or procedures. At any time during this information-retention period, upon request by the
United States or LDEQ, Mosaic shall provide copies of any documents, records, or other information required to be maintained under this Paragraph. 

81.        At the conclusion of the information-retention period provided in the preceding Paragraph,
Mosaic shall notify the United States and LDEQ at least ninety (90) Days prior to the destruction of any documents, records, or other information subject to the requirements of the preceding Paragraph and, upon request by the United States or
LDEQ, Mosaic shall deliver any such documents, records, or other information to EPA or LDEQ. Mosaic shall not dispose of 

  
 60 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
materials following the expiration of its five (5) year retention period more often than once a year. 

82.        In connection with any request for documents, records, or other information pursuant to
this Consent Decree, Mosaic may assert that certain documents, records, or other information are privileged under the attorney-client privilege or any other privilege recognized by federal law, provided that Mosaic shall not assert a legal privilege
for any data, records or information (excluding legal advice) generated or received in connection with Mosaic’s obligations pursuant to the requirements of this Consent Decree. If Mosaic asserts a privilege, it shall provide the following:
(1) the title of the document, record, or information; (2) the date of the document, record, or information; (3) the name and title of each author of the document, record, or information; (4) the name and title of each addressee
and recipient; (5) a description of the subject of the document, record, or information; and (6) the privilege asserted by Mosaic. If Plaintiffs and Mosaic disagree as to whether a particular document or record is privileged, Mosaic shall
deliver such document or record to the United States or LDEQ unless it invokes dispute resolution pursuant to Section XI (Dispute Resolution), in which case, Mosaic shall not have an obligation to deliver such document or record until a final
determination is made, pursuant to the procedures set forth in Section XI (Dispute Resolution), that such document or record is not privileged. 

83.        Mosaic may also assert that information provided pursuant to this Consent Decree is
protected as Confidential Business Information (“CBI”) under the criteria and procedures set forth in 40 C.F.R. Part 2 or LAC 33:I.Chapter 5, provided that: (a) Mosaic shall not assert a CBI claim with respect to any physical,
sampling, monitoring, or analytical data other than data related to: (i) development of new or modified products; (ii) development of new or modified 

  
 61 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
production processes; (iii) production materials or analyses collected for quality control or other manufacturing purposes; or (iv) analyses undertaken for competitive business
purposes; and (b) Mosaic shall not assert a CBI claim for Financial Assurance information required to be provided pursuant to Paragraphs 10.e, 15(e) and 32 of Appendix 2 of this Consent Decree. If Mosaic claims any information related to
Financial Assurance submissions and Cost Estimates is CBI, Mosaic shall submit two versions, one version with the CBI material redacted, and so identified in the document, which will be publicly available, and the second version will contain the CBI
material. 
 84.        This Consent Decree in no way limits or affects any right of entry and
inspection, or any right to obtain information, held by the United States or LDEQ pursuant to applicable federal or Louisiana laws, regulations, or permits, nor does it limit or affect any duty or obligation of Mosaic to maintain documents, records,
or other information imposed by applicable federal or Louisiana laws, regulations, or permits. 
 XIII. EFFECT OF SETTLEMENT/RESERVATION
OF RIGHTS 
 85.        This Consent Decree resolves the civil claims of the United States and
LDEQ against Mosaic and, as to liability arising out of Mosaic’s liability only, The Mosaic Company for the violations at the Facilities alleged in the Complaint filed in this action through the date of the lodging of the Consent
Decree. This Consent Decree also resolves such claims, if any, of the United States and LDEQ against the corporate officers, directors, and employees, acting in their capacities as such, of Mosaic or The Mosaic Company, but only as to liability
arising out of Mosaic’s liability. For continuing violations alleged in the Complaint, provided that Mosaic complies with this Consent Decree at a Facility, as set forth in Paragraph 87, from the date of lodging of the Consent Decree through
its Effective Date, these claims shall also be resolved 

  
 62 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
through the Effective Date of this Consent Decree, as of the Effective Date, for that Facility; and, provided that Mosaic complies with the Consent Decree at a Facility from the Effective Date of
this Consent Decree through the date of termination of this Consent Decree for that Facility pursuant to Section XIX (Termination), these claims shall be finally resolved as of the date the Consent Decree terminates for that Facility. 

86.        Provided that Mosaic is in compliance with this Consent Decree, and subject to the
reservation below, Plaintiffs covenant not to sue or take administrative action, under Section 3008(a) of RCRA, 42 U.S.C. § 6928(a) or a state law counterpart, seeking to require Mosaic’s Facilities to comply with the RCRA
Requirements, with respect to: (a) the generation, treatment, storage, transport, management, and disposal of Bevill-Exempt Wastes that have been commingled with hazardous wastes or otherwise managed in violation of law as alleged in the
Complaint, and that are resolved in accordance with Paragraph 85; (b) wastes that Paragraphs 15 through 18 of this Consent Decree allow to be input to Upstream Operations or Downstream Operations or managed in BHT Recovery Units, IGPUs, GPUs,
Granulation Sump Ditches or with Bevill-Exempt Wastes; and (c) conditions addressed under Paragraphs 23 and 24. Further, provided that Mosaic is in compliance with this Consent Decree, LDEQ covenants not to sue or take administrative action
seeking to require the Phosphogypsum Stack System at Mosaic’s Uncle Sam Facility to comply with otherwise applicable requirements of the Louisiana Solid Waste Management and Resource Recovery Law (La. R.S. 30:2151 et seq.) and the regulations
promulgated thereunder (LAC 33:VII, Subpart 1). (The interface of the Louisiana Solid Waste Management and Resource Recovery Law (La. R.S. 30:2151 et seq.) and the regulations promulgated thereunder (LAC 33:VII, Subpart 1) and Defendant’s
obligations under this Consent Decree is further addressed in the letter from LDEQ dated September 29, 2015.) 

  
 63 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
Nothing in this Paragraph, however, shall affect Plaintiffs’ rights to determine and require necessary Corrective Action Work in accordance with Paragraphs 21 and 22(a)(1), respectively, of
this Consent Decree, or to restrict Non-CD Corrective Action that may be required at a Facility pursuant to Plaintiffs’ residual authorities under federal, state, and local laws. 

87.        The resolution under this Section XIII (Effect of Settlement/Reservation of Rights) of the
Plaintiffs’ civil claims set forth in the Complaint and the Plaintiffs’ covenants not to sue are expressly conditioned upon Mosaic’s timely and satisfactory compliance with the requirements of this Consent Decree. For the purposes of
this Paragraph (and Paragraphs 85 and 86), and with respect to the wastes that Paragraphs 15 through 18 allow to be input to Upstream Operations or Downstream Operations, managed in BHT Recovery Units, IGPUs, GPUs, Granulation Sump Ditches, or with
Bevill-Exempt Wastes, compliance with the Continuing Compliance Criteria set forth in Paragraph 32 constitutes compliance with this Consent Decree. 

88.        The United States and LDEQ reserve all legal and equitable remedies available to enforce
the provisions of this Consent Decree, and Mosaic reserves all legal and equitable defenses available to it in the defense of any such enforcement. This Consent Decree shall not be construed to limit the rights of the United States or LDEQ to
obtain penalties or injunctive relief under the federal and Louisiana environmental statutes or their implementing regulations, or under other federal or Louisiana law regulations or permit conditions, including Section 3008(h) of RCRA, 42
U.S.C. § 6928(h), except as expressly specified in Paragraphs 85 and 86, and Mosaic in any such action shall not assert any defense based upon the contention that such claims raised by the Plaintiffs were or should have been brought in the
instant case under principles of waiver, res judicata, collateral estoppel, issue preclusion, claim preclusion, claim-splitting, or other such defenses. The United States and LDEQ further retain all authority and

  
 64 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
reserve all rights to take any and all actions authorized by law to protect human health and the environment, including Corrective Action Work and Non-CD Corrective Action, and all legal and
equitable remedies to address any imminent and substantial endangerment to the public health or welfare or the environment arising at, or posed by, Mosaic’s Facilities, whether related to the violations addressed in this Consent Decree or
otherwise. 
 89.        This Consent Decree is not a permit, or a modification of any permit, under
any federal, State, or local law or regulation. While this Consent Decree resolves the Parties’ dispute regarding the violations alleged in the Complaint as set forth in Paragraph 85, compliance with the terms of this Consent Decree does not
guarantee compliance with all applicable federal, State, or local laws or regulations. Except as provided in Paragraphs 34, 85, and 86 of this Consent Decree, Mosaic is not relieved of its obligation to achieve and maintain compliance with all
applicable federal, State, and local laws, regulations, and permits; Mosaic’s compliance with this Consent Decree shall be no defense to any action commenced by Plaintiffs pursuant to any such law, regulation, or permit, except
as expressly specified in Paragraphs 34, 85 and 86.
 90.        This Consent Decree does not
limit or affect the rights of the Parties against any third-parties (persons not a Party to this Consent Decree), nor does it limit the rights of third-parties except as otherwise provided by the doctrine of federal preemption or by other applicable
principles of law or precedent. 
 91.        This Consent Decree shall not be construed to create
rights or obligations in, or grant any cause of action to, any third-party. 
 92.        Nothing in
the Complaint filed in this action or in this Consent Decree, including the execution and implementation of this Consent Decree, shall constitute an admission by Mosaic of any violation of the RCRA Requirements or of any of the allegations of the

  
 65 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
Complaint. Mosaic reserves all rights to dispute the factual and legal representations of the Complaint and Consent Decree except in an action to enforce this Consent Decree by a Party. The terms
of this Consent Decree may not be used as evidence in any litigation between the Parties except (a) pursuant to Section XI (Dispute Resolution), (b) in an action to enforce this Consent Decree, or (c) in an action by Plaintiffs in
which Mosaic asserts a defense based on this Consent Decree. 
 XIV. COSTS 

93.        The Parties shall bear their own costs of this action, including attorneys’ fees,
except that the United States and LDEQ shall be entitled to collect costs (including attorneys’ fees) incurred in any action necessary to access Financial Assurance pursuant to Paragraph 25 and Appendix 2 (Financial Assurance) of this Consent
Decree, or to collect any portion of the civil penalty or any stipulated penalties or other costs due under this Consent Decree but not paid by Mosaic. 

94.        LDEQ Costs Incurred in Oversight of Consent Decree. 

(a)        LDEQ may employ, arrange for, or contract with a qualified person to perform oversight
tasks related to the Work performed under this Consent Decree. Mosaic shall bear reasonable and necessary costs incurred by LDEQ for oversight related to the Work performed under this Consent Decree following the Entry Date and as allowed by law.
Following the first anniversary of this Consent Decree, LDEQ may propose to increase the Annual Oversight Cost Cap on an annual basis to reflect cost increases; provided, however, such proposed increase shall not exceed the current inflationary rate
for the specific year. 
  (b)        LDEQ shall keep accurate books and accounts of oversight
costs. Such books and accounts may be audited by Mosaic upon written request. Annually from the 

  
 66 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
Effective Date of this Consent Decree, or at the end of each calendar-quarter if deemed appropriate by LDEQ, LDEQ shall submit to Mosaic an invoice for oversight costs that LDEQ asserts are
recoverable under Paragraph 94(a). The invoice shall describe for each person and for each day the oversight work for which LDEQ seeks reimbursement in sufficient detail to document the amount of time spent on oversight work and to describe the
oversight work performed during the time documented. If Mosaic disagrees with this invoice on the basis that costs incurred by LDEQ are not reasonable, not necessary, or excessive or the invoice fails to provide sufficient information as described
above, then Mosaic may invoke Section XI (Dispute Resolution) of this Consent Decree. Mosaic shall, within sixty (60) calendar Days of receiving the invoice, unless it has invoked Section XI (Dispute Resolution) before this 60 Day period has
passed, remit a check or electronic payment for the amount of those costs made payable to the Louisiana Department of Environmental Quality. Checks shall specifically reference the Facility and invoice number, and be mailed to the following address:

 96.        Any Party may, by written notice to the
other Parties, change its designated notice recipient or notice address provided above. 

97.        Notices submitted pursuant to this Section shall be deemed submitted upon electronic
transmission, unless otherwise provided in this Consent Decree or by mutual agreement of the Parties in writing. 

XVI.  EFFECTIVE DATE 

98.        The Entry Date of this Consent Decree shall be the date of a Final Order by which this
Consent Decree is entered by the Court or by which a motion to enter the Consent Decree is granted, whichever occurs first, as recorded on the Court’s docket. The Effective Date of this Consent Decree shall be the later of the Entry Date of
this Consent Decree or the Entry Date of the Consent Decree resolving claims by the United States and the Florida Department of Environmental Protection against Mosaic relating to Mosaic’s facilities in Florida. The filing or pendency of an
appeal of the Court’s entry of this Consent Decree shall not stay the Effective Date, except as may be otherwise determined pursuant to Paragraph 100 (Modification). In the event that either Consent Decree is not entered by the Court, the
Parties shall jointly stipulate to stay any previously entered Consent Decree. Notwithstanding the foregoing, Mosaic hereby agrees that it shall be bound from the date of its execution of this Consent Decree to perform obligations scheduled in this
Consent Decree to occur prior to the Effective Date. 
 XVII.  RETENTION OF JURISDICTION 

99.        The Court shall retain jurisdiction over this case until termination of this Consent Decree

entered pursuant hereto) or entering orders modifying this Consent Decree, pursuant to Sections XI (Dispute Resolution) and XVIII (Modification), or effectuating or enforcing compliance with the
terms of this Consent Decree. 
 XVIII.  MODIFICATION 

100.      The terms of this Consent Decree may be modified only by a subsequent written agreement of the Parties
to this Consent Decree as set forth herein. Any modifications to the provisions of Appendices 1 through 7, hereto and any other modifications to any other provisions of this Consent Decree that do not constitute a material change to this Consent
Decree may be made without approval by the Court upon written agreement between Mosaic and the United States, after consultation with LDEQ. Any modifications to the provisions of Appendix 8 may be made without approval by the Court upon written
agreement between Mosaic and LDEQ, after consultation with the United States. Any such changes shall become enforceable under this Consent Decree upon execution by Mosaic and the United States (for changes to the Consent Decree or Appendices 1
through 7) or Mosaic and LDEQ (for changes to Appendix 8), shall be made available to the public by EPA and LDEQ (except to the extent such changes contain information determined to be CBI pursuant to Paragraph 83 and 40 C.F.R. Part 2), and shall
periodically be filed by EPA or LDEQ with the Court. Any other modifications agreed to by the Parties shall be effective only upon approval by the Court. Except as otherwise provided in this Paragraph and in Paragraph 102, a Party’s
refusal to agree to a modification of this Consent Decree shall be subject to dispute resolution, but a Party seeking judicial review of such a refusal shall bear the burden of demonstrating that it is entitled to the requested modification based on
a significant change in factual conditions or the law or other reason that would make inequitable the continued application of the Consent Decree without the modification sought.

 101.      In the event that a potential transferee under
Section II (Applicability) of this Consent Decree has agreed to become a party to this Consent Decree and subject to all its terms and provisions, it may do so upon written approval of the United States pursuant to Section II (Applicability) of this
Consent Decree and Section XVIII (Modification), without further order from the Court, in which event a supplemental signature page will be affixed to this Consent Decree and filed with the Court. 

XIX. TERMINATION 

102.      Periodic Review of Work Status. At least once every three (3) years, and more often if the
Parties so agree, the Parties shall meet to review the status of the Work and to evaluate whether discrete portions of the Work have either been completed or may be accomplished and supervised under an EPA or LDEQ administrative order or permit in
lieu of this Consent Decree. If all Parties agree to such a modification, such agreement shall be memorialized in a written modification to this Consent Decree pursuant to Section XVIII (Modification) and shall not require judicial approval. If the
Parties agree that such modifications allow this Consent Decree to be terminated as to one or both Facilities, the Parties shall submit, for the Court’s approval, a joint stipulation terminating the Consent Decree for the relevant Facilities.
The Parties’ inability to reach an agreement under this Paragraph shall not be subject to dispute resolution or judicial review. 

103.      Completion of Work. Within ninety (90) Days after Mosaic concludes that all Work required
under this Consent Decree has been fully performed at a Facility, EPA and/or LDEQ may conduct an inspection of the Facility to be attended by EPA, LDEQ and Mosaic at a mutually agreeable time. Following the inspection, and correction of any problems
or deficiencies noted by EPA, after consultation with LDEQ, Mosaic shall submit one or more 

  
 73 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
written reports by a third-party registered professional engineer in the relevant technical field, certifying compliance with Section V (Compliance Requirements) of this Consent Decree that the
Work has been completed in full satisfaction of the requirements of this Consent Decree. The reports shall indicate the case name and civil action number, and shall be submitted, together with a request for Acknowledgment of Completion, in
accordance with Section VIII (Reporting Requirements) of this Consent Decree. Third-party engineer certification of any of the written reports may be waived at EPA’s discretion, after consultation with LDEQ. 

104.      If, after review of the written report(s) and certification and consultation with LDEQ, EPA determines
that any portion of the Work has not been completed in accordance with this Consent Decree, EPA will notify Mosaic in writing of the activity(ies) and/or obligation(s) that must be undertaken to complete the Work. EPA will set forth in the notice a
schedule for performance of the activity(ies) and/or obligation(s) required under the Consent Decree, or will require Mosaic to submit a schedule for EPA approval pursuant to Section V (Compliance Requirements) of this Consent Decree. Mosaic shall
perform all activities described in the notice in accordance with the specifications and schedules established therein, subject to Mosaic’s right to invoke the dispute resolution procedures set forth in Section XI (Dispute Resolution) of this
Consent Decree. 
 105.      If EPA concludes, based on the initial or any subsequent request for an
Acknowledgment of Completion by Mosaic, and after reasonable opportunity for review and comment by LDEQ, that the Work has been fully performed in accordance with this Consent Decree, EPA will so notify Mosaic in writing, which notice shall
constitute the Acknowledgment of Completion. 

  
 74

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 106. Termination. After Mosaic has completed the requirements set forth in Paragraphs
102 and 103 of this Section, has obtained an Acknowledgment of Completion, has complied with all other requirements of this Consent Decree, and has paid the civil penalty and any accrued stipulated penalties as required by this Consent Decree,
Mosaic may serve upon the United States and LDEQ a Request for Termination, stating that Mosaic has satisfied those requirements, together with all necessary supporting documentation. A Request for Termination may address one or both of
Mosaic’s Facilities. 
 107. Following receipt by the United States and LDEQ of Mosaic’s Request for Termination, the Parties
shall confer informally concerning the Request and any disagreement that the Parties may have as to whether Mosaic has satisfactorily complied with the requirements for termination of this Consent Decree. If the United States, after consultation
with LDEQ agrees that the Consent Decree may be terminated for one or both Facilities, the Parties shall submit, for the Court’s approval, a joint stipulation terminating the Consent Decree as to the relevant Facilities. 

108. If the United States, after consultation with LDEQ, does not agree that the Consent Decree may be terminated as to one or both
Facilities, Mosaic may invoke Dispute Resolution under Section XI (Dispute Resolution) of this Consent Decree. However, all time periods and deadlines established under Section XI (Dispute Resolution) shall be extended by sixty (60) Days, or
more by the agreement of the Parties. 
 XX.  PUBLIC PARTICIPATION 

109. This Consent Decree shall be lodged with the Court for a period of not less than forty-five (45) Days for public notice and comment
in accordance with 28 C.F.R. § 50.7 and La R.S. 30:2050.7. The United States reserves the right to withdraw or withhold its consent if the 

  
 75 

Table of Contents

 Mosaic Consent Decree – EPA Region 6 and LDEQ 

 

 
comments regarding the Consent Decree disclose facts or considerations indicating that the Consent Decree is inappropriate, improper, or inadequate. Mosaic and The Mosaic Company consent to entry
of this Consent Decree without further notice and agree not to withdraw from or oppose entry of this Consent Decree by the Court or to challenge any provision of the Consent Decree, unless the United States has notified Mosaic in writing that it no
longer supports entry of the Consent Decree. Further, the parties agree and acknowledge that final approval by LDEQ and entry of this Consent Decree is subject to the requirements of LA. R.S. 30:2050.7, which provides for public notice of this
Consent Decree in the newspapers of general circulation and the official journal of the parish in which the Facilities are located, an opportunity for public comment, consideration of any comments, and concurrence by the State of Louisiana Attorney
General. Evidence of final approval of this Consent Decree by LDEQ shall be LDEQ’s execution of a Motion to Enter this Consent Decree. LDEQ reserves the right to withdraw or withhold consent and will not join in the filing of a Motion to Enter
this Consent Decree if the state Attorney General raises objections or if comments regarding this Consent Decree disclose facts or considerations which indicate that this Consent Decree is inappropriate, improper or inadequate. 

XXI.  SIGNATORIES/SERVICE 

110.      Each undersigned representative of Mosaic and The Mosaic Company, the Assistant Attorney General for
the Environment and Natural Resources Division of the Department of Justice, or her designee, and the Secretary of the Louisiana Department of Environmental Quality certifies that he or she is fully authorized to enter into the terms and conditions
of this Consent Decree and to execute and legally bind the Party he or she represents to this document. The undersigned Attorney General of Louisiana is authorized to and as

of Civil Procedure and any applicable Local Rules of this Court including, but not limited to, service of a summons. 
 XXII. INTEGRATION

 112.      This Consent Decree and its Appendices constitute the final, complete, and exclusive
agreement and understanding among the Parties with respect to the settlement embodied in the Consent Decree and supersedes all prior agreements and understandings, whether oral or written, concerning the settlement embodied herein. Other than the
Appendices, which are attached to and incorporated in this Consent Decree, no other document, nor any representation, inducement, agreement, understanding, or promise, constitutes any part of this Consent Decree or the settlement it represents, nor
shall it be used in construing the terms of this Consent Decree. 
 XXIII. FINAL JUDGMENT 

113.      Upon approval and entry of this Consent Decree by the Court, this Consent Decree shall constitute a
final judgment of the Court as to the United States, LDEQ, Mosaic and The Mosaic Company. The Court finds that there is no just reason for delay and therefore enters this judgment as a final judgment under Fed. R. Civ. P. 54 and 58.

 APPENDIX 1 

Table of Contents

 APPENDIX 1- OPERATING AND CLOSURE REQUIREMENTS FOR THE 

PHOSPHORIC ACID PRODUCTION INDUSTRY IN LOUISIANA 

ATTACHMENT A: SITE ASSESSMENT, REPORTING, AND CORRECTIVE ACTION 

SAMPLING AND ANALYSIS WORKPLAN 

Defendant’s obligations pursuant to this Attachment A are governed by Paragraph 21 of the Consent Decree. 

 

	1)	The Defendant shall submit to LDEQ and/or EPA for approval an Outline for a Sampling and Analysis Workplan (“Outline”), for carrying out the required monitoring, testing, analysis, and reporting.

  

	2)	The Defendant shall submit to LDEQ and/or EPA a Sampling and Analysis Workplan (“Workplan”), unless Defendant has already submitted a Sampling and Analysis Workplan that has been approved by LDEQ and/or EPA
and is consistent with this Attachment. 

  

	3)	The Sampling and Analysis Workplan shall be designed to determine the presence, magnitude, extent, direction, and rate of movement of any hazardous waste, hazardous waste constituents, and/or constituents of concern
(“COC”) as defined by the Louisiana Risk Evaluation and Corrective Action Program (“RECAP”) and EPA (for Radionuclides) within and beyond the Facility boundary. COCs shall be limited to those contaminants that are reasonably
likely to be found at the Facility. The Workplan shall document the procedures the Defendant shall use to assess sampling and analysis data that is generated and that relate to the purposes of this Attachment. The Workplan shall also document the
procedures the Defendant shall use to conduct those activities necessary to: characterize the source(s) of contamination; characterize the potential pathways of contaminant migration; define the degree and extent of contamination; and identify
actual or potential human and/or ecological receptors. The Defendant may implement the work contained in the Workplan in a multi-phased approach. A specific schedule for expeditious implementation of all activities shall be included in the Workplan.
At a minimum, the Workplan for assessment shall include the following [All requirements below would be Facility-specific]:  

  

	 	(a)	A sediment and/or soil, as appropriate, sampling and analysis section to collect and analyze representative sediment and/or soil samples to determine the nature and extent of potential contamination, both vertically and
horizontally. Areas of sampling shall include process areas, areas of historical spills and/or historical contamination, areas of waste management, stormwater and non-Process Wastewater ditches and ponds, and ditches associated with National
Pollutant Discharge Elimination System (“NPDES”) outfall(s). The Workplan must define the number, location, and depth of the samples, and the parameters for analysis. The number of samples shall be sufficient to produce a 95% confidence
level that the results are representative of the environmental conditions found at each location. 

  
 1 

Attachment A: Phosphogypsum Stack System Construction and Operational Requirements 

Table of Contents

	 	(b)	A Surface Water (including Run-Off) sampling and analysis section to determine the nature and extent of any contaminated Surface Water flowing from the portions of the Facility adjacent to and down-gradient from the
unlined areas of Facility operations (to be defined). The Workplan shall define the number, location, and depth of samples, and the parameters for analysis. 

  

	 	(c)	A Groundwater sampling and analysis section to characterize the Groundwater quality and the extent of any Groundwater contamination, both vertically and horizontally, that may be migrating from Defendant’s
Facility. This shall include unlined areas, and/or lined areas which do not meet the requirements of Attachment C, within the Facility operations (including the Phosphogypsum Stack System and other impoundments and ponds). The Workplan shall define
the number, location, and depth of Groundwater samples (either from existing wells included in the current Groundwater monitoring program, temporary wells, or direct-push technology), and the parameters for analysis. 

 

	 	(d)	Upon confirmation of the existence of hazardous waste, hazardous constituents and/or COCs in Groundwater emanating from the Facility’s designated Point(s) of Compliance at concentrations exceeding the applicable
RECAP standards, a section addressing a potable well survey within a  1⁄2 mile radius of the Facility including a schedule for sampling of each well, and the
parameters for analysis shall be included. Upon confirmation of an exceedance of applicable RECAP Groundwater Screening standards in any of the potable wells, the well survey will be extended by  1⁄2 mile radial increments in the appropriate direction depending on the results of the initial well survey. 

  

	 	(e)	In the event an area of investigation is identified, the ecological checklist (RECAP Form 18) should be completed and included in the plan. 

 

	 	(f)	A Project Management Plan. 

  

	 	(g)	A Data Collection Quality Assurance Project Plan for new sampling and analysis. 

  

	 	(h)	A Data Management Plan for new sampling and analysis. 

  

	 	(i)	A timeline for work detailed above and a schedule for the submission of progress reports, including a draft Sampling and Analysis Report, and a final Sampling and Analysis Report. 

 

	4)	Concurrent with the submission of the Sampling and Analysis Workplan, the Defendant shall submit a Health and Safety Plan with respect to the work to be performed. 

 

	5)	 Upon receipt of LDEQ’s and/or EPA’s approval of the Workplan, the Defendant shall implement the approved Workplan pursuant to the terms and
schedules contained therein. Upon completion of the Agency-approved sampling activities proposed in the Workplan, the 

  
 2 

Attachment A: Phosphogypsum Stack System Construction and Operational Requirements 

Table of Contents

	 	
Defendant shall submit to LDEQ and/or EPA for approval a draft Sampling and Analysis Report, pursuant to the requirements and schedule contained in the approved Sampling and Analysis Workplan.
Upon approval of the draft Sampling and Analysis Report by LDEQ and/or EPA, the Defendant shall submit a final Sampling and Analysis Report. 

  

	6)	LDEQ and/or EPA acknowledge that the Defendant may have completed some of the tasks required by this Attachment and/or that the Defendant has available pertinent information and data required by this Attachment. This
previous work may be used to meet some of the requirements of this Attachment, upon submission to and written approval by LDEQ and/or EPA. 

  

	7)	The Defendant shall for COCs when appropriate to distinguish site-related constituent concentrations from naturally-occurring concentrations or as default screening action levels when the screening action levels are
less than the naturally occurring Background Concentration. 

 ADDITIONAL WORK 

 

	8)	Based on work performed under the Workplan described above, LDEQ and/or EPA may determine that additional monitoring, testing, analysis, and/or reporting is necessary to ascertain the nature and extent of any hazard to
human health or the environment that may be presented by the presence or release of hazardous wastes and/or hazardous constituents at or from the Facility. If LDEQ and/or EPA determine that such additional work is necessary, LDEQ and/or EPA will
notify the Defendant in writing and specify the basis for its determination that additional work is necessary. 

 MINIMUM
QUALIFICATIONS FOR PERSONNEL

 APPENDIX A-1 

Screening Criteria- Action Levels for Assessment of Corrective Action 

 

	I.	Definition 

 Action levels are conservative health-based concentrations of hazardous
wastes and/or hazardous constituents determined to be indicators for the protection of human health or the environment. Action levels shall be set by LDEQ using their Risk Evaluation/Corrective Action Program (RECAP) and/or EPA for all hazardous
wastes and/or hazardous constituents identified through Attachment A which LDEQ and/or EPA has reason to believe may have been released in soils, sediments, or Surface Water, or in Groundwater from the Facility into the environment. Should the
concentration of hazardous wastes and/or hazardous constituents in soils, sediments, or Surface Water, or in Groundwater (at the Point(s) of Compliance) exceed the RECAP action levels established for any environmental medium by LDEQ, LDEQ and/or EPA
may require the Respondent to conduct a Risk Assessment and/or perform Corrective Action to achieve final RECAP standards established pursuant to RECAP. If LDEQ and/or EPA determine that concentrations of hazardous wastes and/or hazardous
constituents released from the Facility, below established action levels, may pose a substantial threat to human health or the environment given site-specific exposure conditions, cumulative effects, ecological concerns or other factors, then LDEQ
and/or EPA may require a Risk Assessment pursuant to Paragraph 17b of Attachment A. 
 Action levels shall be concentration levels that
satisfy the following criteria. 
  

	II.	Soils 

 Action levels for COCs in soils shall be derived from the levels established by LDEQ RECAP or
EPA’s Regional Screening Levels. In compliance with RECAP, industrial soil levels can be applied for onsite soil as long as the current site use remains industrial. 
  

	III.	Sediment 

 RECAP Screening Standards and Risk Standards are not available for constituents in sediment.
Screening standards and risk standards shall be developed as follows: 
 1.        Site specific
sediment standards to serve as screening standards and action levels shall be developed under RECAP (2003)’s Management Option 3 (or its replacement) and shall address: 1) toxicity to benthic and aquatic organisms, and 2) bioaccumulation
and potential risks to ecological receptors and human health. 
 2.        Constituents of concern
(COCs) whose maximum concentration exceeds the site specific screening standard shall be identified as site-related COCs and RECAP (2003) Management Option 3 (or its replacement) risk standards for sediment shall be developed to addressed
constituent-specific concerns. 

  
 9 

Appendix A-1: Screening Criteria – Action Levels for Assessment of Corrective Action 

Table of Contents

	IV.	Groundwater 

 Action levels for COCs in Groundwater at the Point(s) of Compliance shall
be concentrations specified as: 
 1.        Maximum Contaminant Levels (“MCLs”)
established at 40 CFR Part 141, or the applicable state law (RECAP calculated levels based on the Groundwater classification of the underlying water bearing zone/zones) or Facility permit requirements for the State in which the Facility is located,
these action levels must meet appropriate aquatic water quality criteria if it is determined through the process outlined in Attachment A that Groundwater has the potential to impact Surface Water (Point of Exposure). 

2.        For facilities where the MCL is the most stringent standard for individual contaminants, if
the Background Concentration exceeds the MCL, representative Natural Background will be the default Groundwater standard, unless the applicable state law or Facility permit is more stringent than Natural Background for that contaminant, in which
case the applicable state law or Facility permit will provide the appropriate standard for that contaminant. 
  

	V.	Surface Water 

 Action levels for COCs in Surface Water shall be specified as: 

1.        LDEQ’s Surface Water Quality Criteria 

2.        If action levels are not available from the screening values, Ambient Water Quality Criteria
as established by the Clean Water Act will be used.

III. Construction of New Perimeter Dikes 
 (1) Design.

 (a) Site investigation. The general area desired for construction of a Perimeter Dike shall be carefully inspected by an Engineer prior
to selection of the exact location for the Perimeter Dike. Areas of uneven natural subsidence, sinkholes, pockets of organic matter, or other unstable soils shall be avoided, unless special provisions are made for their mitigation. 

(b) Soil testing. A program of soil sampling and testing adequate to determine the characteristics of the foundation material that will
support the proposed Perimeter Dike and of the material to be used for construction of the Perimeter Dike shall be performed. Sampling shall include borings, test pits, or in-place samples from the associated exposed excavation face. All borings
and/or test pit explorations shall be logged using a recognized engineering soil classification system, with location and depths of all samples recorded on the Log. Tests to determine in-place densities, shear-strength, and permeabilities of the
foundation and embankment soils shall be performed. Tests on foundation soils shall be performed either on undisturbed samples or on the in-place soil. Tests on embankment soils shall be performed on samples remolded to the densities and moisture
contents to be used in construction. 
 (c) Cross section design. 

(i) The crest on the top of the Perimeter Dike shall be graded toward the Inside or the Outside Slope. If the Perimeter Dike exceeds ten
(10) feet in height and crest runoff is directed toward the Outside Slope, runoff controls shall be used to protect the Outside Slope against erosion. Both Inside and Outside Slopes shall be no steeper than two and one-half
(2.5) horizontal to one (1.0) vertical. Seepage control shall be provided by means of a Liner constructed in accordance with Section VI: Construction Requirements for New Phosphogypsum Stack Systems or Lateral Expansions of Existing
Phosphogypsum Stack Systems, of this Attachment, placed on the Inside slope of the Perimeter Dike. 
 (d) Freeboard provisions 

(i) The design Freeboard of an above-grade Perimeter Dike shall not be less than five (5) feet unless a design Freeboard of less than
five (5) feet is justified based on results of seepage and stability analyses and Wave Run-Up analyses. However, in no event shall the design Freeboard of an above-grade Perimeter Dike be less than three (3) feet. 

(e) Design factors of safety and slope stability of Perimeter Dikes. 

(i) Stability analysis. A seepage or flow net analysis shall be made, when applicable, for use in the stability analysis. The stability
analysis shall consider the minimum fluid level as well as the fluid level at the design Freeboard on the upstream slope of the Perimeter Dike, and possible fluctuations of the tail water level.

Table of Contents

 (ii) Design safety factors for Perimeter Dikes – The Engineer shall use the safety factors
identified in Section VI (Construction Requirements for New Phosphogypsum Stack Systems or Lateral Expansions of Existing Phosphogypsum Stack Systems) for Perimeter Dikes; any safety factor that does not meet a minimum of 1.5 is subject to approval
by LDEQ and/or EPA prior to construction of the Perimeter Dike. 
 (2) Site preparation. In accordance with specifications provided by the Engineer, ground
which will become the foundation of Perimeter Dikes shall be stripped of vegetation and organic detritus or residue, including muck, mud, slimes, or other material which would flow or undergo excessive consolidation under heavy loading. All earth
foundation surfaces on which fill is to be placed shall be scarified or moistened and compacted prior to spreading of first course of fill material, and the Perimeter Dike base shall be well drained during construction, except when placing hydraulic
fill. 
 (3) Material to be used. Material used for Perimeter Dikes shall be free of extraneous matter that could affect the compactability, density,
permeability, or shear strength of the finished Perimeter Dike (e.g. stumps, vegetation, trees, palmettos, debris). Tailings may be used for Perimeter Dike fill when such a completed Perimeter Dike will meet the seepage and structural requirements
above. 
 (4) Process Wastewater control design. Conveyance ditches, pumps, pipes, and hydraulic structures located within a Phosphogypsum Stack System
shall have adequate capacity to circulate the Process Wastewater stream(s), if applicable, and to contain or transfer runoff on the Process Watershed upstream of the water control structures resulting from a storm event generating a 100-year
rainfall in twenty-four (24) hours, while maintaining at the same time the design Freeboard of the Perimeter Dike. If provisions are made to contain all or part of the storm surge resulting from such event within the Phosphogypsum Stack System
upstream from the conveyance system or water control structures, then the transfer capacity of the ditches, pumps, pipes, and related structures may be reduced accordingly. 

(5) Methods of construction: 
 (a) Each new
Perimeter Dike shall be constructed to meet or exceed the minimum safety requirements of this Section and the specifications and design for that Perimeter Dike. Appropriate earthmoving equipment shall be used to place materials in Perimeter Dike
construction. The soil shall be compacted and density tests shall be performed to ensure that the designed densities are obtained. A representative of the Third-Party Engineer shall be present on the site during construction of the Perimeter Dike
and Liner, and during construction and installation of spillways and penetrations through the Perimeter Dike or Liner. LDEQ and the EPA shall be advised of the date on which construction of a new Perimeter Dike will begin. 

(b) Areas around any water level control structure pipe, any other conduit, or any surface of discontinuity between materials within the mass
of the Perimeter Dike shall be carefully inspected to avoid potential concentration of seepages and to ensure that soils under and around a culvert are uniformly compacted and are in continuous contact with the external culvert surface.

thermoplastic at least thirty (30) mils thick, with a maximum water vapor transmission rate of 2.4 grams per square meter per day, have chemical and physical resistance to materials it may come in contact with, and withstand exposure to the
natural environmental stresses and forces throughout the installation, seaming process, and settlement of the Phosphogypsum during the closure and long-term care period. A protective soil layer at least twenty-four (24) inches thick, which will
sustain vegetation, shall be put on top of the Geomembrane prior to final closure. Material specifications, type of vegetation, installation methods, and compaction specifications shall be adequate to protect the barrier layer from damage during
placement of the protective cover, root penetration, resist erosion, and remain stable on the final design slopes. 
 c. An alternate Final
Cover for the top gradient, consisting of a barrier layer, a protective soil layer over the barrier layer and vegetative growth, shall be designed to meet the performance standards for Final Cover and provide, at a minimum, the equivalent degree of
protection (e.g., minimize infiltration, erosion, etc.) as would be achieved if the Final Cover conformed with the criteria set forth in Section III(7)(c)1.a and b, above. The request for an alternate Final Cover for the top gradient must be
submitted and approved by LDEQ and/or EPA. 
 2. Side slopes and all other grades, except those grades associated with the top gradient and
with Cooling/Surge Ponds, Auxiliary Holding Ponds (AHP), lime treatment sludge ponds within the definition of the Phosphogypsum Stack System, Process Wastewater and Leachate channels (including cooling channels) and ditches, and Toe drainage swales,
shall be designed to minimize erosion of the Final Cover material and infiltration. Such designs shall consider the erosion susceptibility of the material proposed for Final Cover relative to historical rainfall patterns for the area, the ability to
establish and maintain vegetation and special maintenance procedures proposed to address and minimize infiltration and erosion. In addition, for the side slopes of the Phosphogypsum Stack, the following criteria shall be applicable: 

a. The side slopes shall be no steeper than three (3)-feet horizontal run to one (1)-foot vertical rise (3H:1V).

 b. The Final Cover shall be a minimum of six (6) inches of clay to silty clay soil with a
fines content (i.e., percent by dry weight finer than the U.S No. 200 Standard Sieve Size) no less than 30% that can achieve a permeability no greater than 1x10-7 cm/sec. 

c. Agricultural lime or dolomitic limestone will be applied, if needed, over the surface of the side slopes and plowed into the upper six
(6) to eight (8) inches of the phosphogypsum. The Final Cover, as specified in 2.b, above, will be installed over the amended phosphogypsum. 

3. Cover for the side slope swales, if an aspect of the Phosphogypsum Stack closure design, shall be designed to minimize ponding and low
spots, and minimize erosion and infiltration, and at a minimum consist of: 
 (i) A barrier layer which may be either a Geomembrane Liner
or re-compacted soil. 
 (ii) An adequate protective soil layer over the barrier layer that can sustain vegetation. 

(iii) Unless an alternative cover is submitted to and approved by LDEQ and/or EPA, the barrier layer and the protective soil layer for the
side slope swales shall conform to the minimum criteria specified in Section III(7)(c)1.a&b, above, except that the minimum thickness of the Geomembrane if used in side slope swales shall be 60-mil (e.g. 60-mil HDPE). The alternative cover, if
requested, shall be designed to meet the performance standards for Final Cover and provide, at a minimum, the equivalent degree of protection (e.g., minimize infiltration, erosion, etc.) as would be achieved if the Final Cover conformed to the
criteria set forth in Section III(7)(c)1.a&b, above. 
 4. Final Cover for Cooling/Surge Ponds, cooling channels, AHPs, lime treatment
sludge ponds within the definition of the Phosphogypsum Stack System, Toe drainage swales, and Process Wastewater and Leachate channels or ditches of the Phosphogypsum Stack System, once the Process Wastewater, Leachate and any sludges removed have
been addressed pursuant to Section III(6)(c)1-2 of this Attachment, shall be designed to control, minimize or eliminate the post closure escape of Phosphogypsum, Process Wastewater, Leachate and contaminated runoff to ground and Surface Waters, and
also minimize ponding (except in such circumstances where LDEQ approves use of these units for process water storage), minimize infiltration and erosion, and the need for further maintenance. Such a design, depending on the activities under Section
III(6)(c)1-2 and the performance standards herein, may require providing a suitable barrier layer (e.g., Geomembrane, re-compacted soil) and an adequate protective soil layer that can sustain vegetation. In addition, the closure design shall at a
minimum include material specifications (e.g., soil, fill material), vegetation type, installation methods (e.g., grading, excavation), and compaction specifications adequate to meet the performance standards. 

5. The closure design plan shall describe provisions for cover material for long-term care erosion control, filling other depressions,
maintaining Berms, vegetation and general maintenance of the Phosphogypsum Stack System, and shall specify the anticipated source and

II. Cost Estimate 

1.         Unless Defendant has provided the following submission to EPA prior to the Lodging of the Consent Decree
and such submission has already been approved by EPA, within thirty-five (35) Days of the Lodging of this Consent Decree, Defendant shall submit to EPA for approval its initial Cost Estimate. In such case, and if the United States thereafter
moves for entry of the Consent Decree, such motion shall be deemed approval of such initial Cost Estimate. 

a.         The initial Cost Estimate, except as set out below in Paragraph 1.b for Financial Assurance
being provided pursuant to Paragraph 10.a(1)(c), shall include a detailed written Cost Estimate for Phosphogypsum Stack System Closure and Long Term Care for each Facility, including but not limited to the cost of cover material, topsoil, seeding,
fertilizing, mulching, labor, land surface care, and groundwater monitoring, collection and analysis and any other costs of compliance with Appendix 1, Attachment D. The Cost Estimate shall be calculated based on the point in time when the manner
and extent of the operation of the Phosphogypsum Stack System would make the Phosphogypsum Stack System Closure and Long Term Care the most expensive. All Cost Estimates shall be based on what it would cost to hire a Third Party to complete
Phosphogypsum Stack System Closure and Long Term Care in that year, except as provided in Paragraph 1.c., below. Defendant shall include as part of its initial Cost Estimate the information specified in Attachments B and C of this Appendix. 

b.         If Defendant is providing Financial Assurance in accordance with Paragraph 10.a(1)(c),
then the initial Cost Estimate shall consist of a written Cost Estimate in the form specified in Attachments B and C. The Cost Estimate shall be calculated based on the December

2011 configuration of the Phosphogypsum Stack System(s) at the Operating Facility and Closing Facility (“Operating and Closing Facilities”) with the configuration of the Phosphogypsum
Stack Systems for the Operating and Closing Facilities being updated every five (5) years thereafter (e.g., December 2016, December 2021). All Cost Estimates shall be based on what it would cost to hire a Third Party to complete
Phosphogypsum Stack System Closure and Long Term Care in that year, except as provided in Paragraph 1.c., below. 

c.         Subject to the conditions for access set forth below, Defendant may, if the conditions of
this Paragraph 1.c. are met, provide a Cost Estimate that includes a cost for soil from a borrow area at the Facility, based on information provided by the Defendant describing the soil borrow areas to be used (e.g., location), in lieu of the cost
to obtain soil from a Third Party. In that event, Defendant agrees that the United States and LDEQ, in addition to their right to Financial Assurance as set forth in the Consent Decree, shall have the same legal right of access to and use of such
soil, and any equipment necessary to access and process such soil, as Defendant would have. Defendant shall confirm with its Updated Cost Estimate submittal required under Paragraph 4, below, that the United States and LDEQ continue to have a right
to access and use the soil, that the soil available is sufficient for closure of the Phosphogypsum Stack System, and that Defendant knows of no reasons as to why the United States and LDEQ, or their representatives, could not have access to and use
of the borrow area(s) and soil. If, for any reason, Defendant or EPA determines that such access cannot be had, or that the available soil in the borrow area is insufficient for closure of the Phosphogypsum Stack System, then Defendant in its next
annual Updated Cost Estimate or ninety (90) Days prior to Phosphogypsum Stack System Closure shall submit to EPA a revised Cost Estimate recalculating the soil cost either: (i) based on the cost of soil from a substitute borrow area at the
Facility; (ii) based on the cost of soil and transportation from a substitute borrow area in the vicinity of the Facility on property owned by Mosaic Fertilizer, LLC; or (iii) if such substitute borrow area is not available, as a cost of a
Third Party buying the soil for closure of the Phosphogypsum Stack System, and shall provide any additional or alternative Financial Assurance necessary to cover this cost. If Defendant has established Financial Assurance pursuant to Paragraph
10.a(1)(c) of this Appendix, then such additional cost shall be covered by the Corporate Guarantee until such time as the trust fund is fully funded. Nothing in this Paragraph 1.c. shall be construed as transferring to the United States, LDEQ or
their representatives any obligation that Defendant may have under the law, including permit requirements, to properly manage, close and/or remediate the soil borrow areas, or otherwise creating such obligations for the United States and/or LDEQ, or
their duly designated representatives. 
 2.         Each Cost Estimate shall be calculated as follows: 

a.         In Current Dollars if Defendant provides Financial Assurance under Section III.A (Type A
Financial Assurance), below; or 
 b.         In Current Dollars for Phosphogypsum Stack System
Closure and using NPV for Long Term Care if Defendant provides the Financial Assurance pursuant to Section III.B (Type B Financial Assurance), below. NPV shall be calculated using the 30-Year Treasury Constant Maturity Rate, averaged for the
previous twelve (12) months (using the average spot rate for each month) from the date of the annual Cost Estimates, and discounted over the time period for which Long Term Care is required.

 3.         Defendant shall not include in any Cost Estimate any credit
for salvage value or a zero cost for handling hazardous waste with potential future value, as set forth in LAC 33:V.3705.A.3-4. 

4.         Defendant shall submit the Updated Cost Estimate, together with supporting documentation, to EPA in the
following manner: 
 a.         Defendant shall submit annually to EPA an Updated Cost Estimate
reflecting inflationary adjustments to the initial Cost Estimate or prior Updated Cost Estimate, except as set forth in Paragraph 4.c, below. Such adjustment may be made by either method in Paragraph 4.a.(1) or 4a.(2) below, except as otherwise
required in this Appendix: 
 (1) Recalculating the costs, in Current Dollars (i.e., OSWER Directive No. 9476.00- 5,
Section 4.4.1); or 
 (2) Using an inflationary factor derived from the most recent Implicit Price Deflator for the Gross National
Product published by the U.S. Department of Commerce in its Survey of Current Business, in the manner as specified by LAC 33:V.3705.B and LAC 33:V.3709.B. If the Cost Estimate is due by the end of February, the Defendant shall:
(i) use the Implicit Price Deflator for the Gross National Product published for Q1, Q2 & Q3 of the prior year, calculate the change in the Deflator between Q1 and Q2, and the change in Deflator between Q2 and Q3, take the average of
these values, and add this average to the Q3 Deflator to impute a Q4 Deflator; or (ii) if the Implicit Price Deflator for the Gross National Product has not been published for Q3 of the prior year by February 10 of the following year,
Defendant shall calculate the change in the published Deflator between Q1 and Q2, adding this value both to the Deflator for Q2 to impute a Q3 Deflator and to the imputed Q3 Deflator to impute a Q4 Deflator. If Defendant calculates imputed Deflators
by using an average of the change in Deflators from prior quarters, because the actual Implicit Price Deflator for Q3 or Q4 were not then available, annual inflationary adjustments in subsequent years shall be based on the actual Implicit Price
Deflator, as and when published values become available. An example of the inflationary factor calculation is provided in Attachment B of this Appendix. 

b.         Defendant shall submit for the Updated Cost Estimate, unless required to provide an Updated
Cost estimate pursuant to Paragraph 4.c., below, a supplement to the Initial Closure Plan updating any new information (e.g., revised closure schedule) and Attachments B and C of this Appendix, except that if Defendant is providing Financial
Assurance pursuant to Paragraph 10.a.(1)(c), then Defendant shall provide only Attachment B. 

c.         Defendant shall: 

(1) If providing Financial Assurance other than pursuant to Paragraph 10.a.(1)(c), submit every five (5) years for the annual Updated
Cost Estimate, a Cost Estimate with supporting documentation and an updated Initial Closure Plan (if needed), reflecting cost adjustments (e.g., revised treatment protocols, additional studies; treatment costs, material and labor cost increases,
etc.) as specified in Paragraph 4.c.(3), below. Defendant shall provide the Updated Cost Estimate and associated documentation five (5) years after the submittal of the initial Cost Estimate (pursuant to Paragraph 1.a. of this Appendix).
Defendant shall also provide such an Updated Cost Estimate for a Facility: (i) in the event of a re-evaluation of when the manner and extent of the operation of the Phosphogypsum Stack System makes the Phosphogypsum Stack System Closure and
Long Term Care the most expensive; (ii) with the submittal of the Permanent Phosphogypsum Stack System Closure Plan as specified in Appendix

1, Attachment D of the Consent Decree; and (iii) thirty (30) Days prior to a Facility transfer with the information requested pursuant to Paragraph 34 of this Appendix. 

(2) If providing Financial Assurance pursuant to Paragraph 10.a.(1)(c), submit every five (5) years for the annual Updated Cost Estimate,
(i) an updated Initial Closure Plan, including detailed Cost Estimate information consistent with the level of detail in Section 3 (and associated Tables) and Attachment 1 (and associated Tables) of the draft 2012 Initial Closure Plans
provided by Defendant to EPA and LDEQ prior to the lodging of the Consent Decree and (ii) Attachments B and C. The updated Initial Closure Plan and Updated Cost Estimate shall reflect cost adjustments (e.g., (as applicable), revised treatment
protocols, additional studies; revised programmatic and administrative needs; treatment costs, material, and labor cost increases; etc.) and the configuration of the Phosphogypsum Stack System as of December of the prior year (e.g., stack height,
acreage to be closed, number of side slope and/or toe drains, volume of process wastewater, leachate, and sludge (within the Phosphogypsum Stack System) to be managed, updated aerial photographs, updated engineering drawings of the Phosphogypsum
Stack System, any new components (e.g., cooling pond, ditches)). Such costs shall be adjusted as specified in Paragraph 4.c.(3) below. Defendant shall provide the Updated Cost Estimate and Initial Closure Plan under this Paragraph in 2017, with
subsequent Updated Cost Estimates and updated Initial Closure Plans every five (5) years thereafter (e.g., 2022, 2027). Defendant shall also provide such an Updated Cost Estimate for a Facility: (i) at least sixty (60) Days prior to
the Defendant constructing a lateral expansion at a Facility referenced in Paragraph 29.b; (ii) with the submittal of the Permanent Phosphogypsum Stack System Closure Plan as specified in Appendix 1, Attachment D of the Consent Decree; and
(iii) thirty (30) Days prior to a Facility transfer with the information requested pursuant to Paragraph 34 of this Appendix, unless such Updated Cost Estimate has been performed for such Facility within the prior two (2) years. The
submittal of an Updated Cost Estimate under Paragraph 4.c.(2)(i)&(ii), above, shall not alter the five (5)-year schedule for receipt of an Updated Cost Estimate under this Paragraph. 

(3) An Updated Cost Estimate submitted under this Paragraph 4.c. shall be adjusted by recalculating the costs, in Current Dollars, as set
forth in Paragraph 4.a.(1), above. 
 (a) In the event a specific cost needed to prepare the Updated Cost Estimate has been
updated pursuant to Paragraph 4.a.(1), above, within one (1) year, Defendant may adjust that specific cost pursuant to Paragraph 4.a.(2), above. 

(b) In the event a specific cost needed to prepare the Updated Cost Estimate has not been updated pursuant to Paragraph
4.a.(1), above, within one (1) year and is not otherwise available, then Defendant may utilize the most recent update of that specific cost, and adjust that prior cost pursuant to Paragraph 4.a.(2), above, provided that Defendant identifies the
specific cost and includes a brief explanation for adjusting the cost pursuant to Paragraph 4.a.(2), above. 

d.        If providing Financial Assurance under Section III.B (Type B Financial Assurance), in
addition to Paragraphs 4.a.-4.c., Defendant shall submit with the initial Cost Estimate and Updated Cost Estimate the calculation and documentation for the average discount rate used for the NPV. In addition, the inflation factor to be used to
inflate Long Term Care costs for purposes of deriving the NPV of Long Term Care shall be the mathematical average of the calculated inflation factors for each year over a five (5)-year period. Each year’s calculated inflation factor shall be
the product of dividing the GDP Deflator for the relevant year by the GDP Deflator for the year immediately prior, beginning with the first year in which the GDP Deflator is an estimate and for each year thereafter until the fifth year. The Gross
Domestic

Product (GDP) Deflator is as specified in the “GDP (Chained) Price Index” of the Gross Domestic Product Deflators Used in the Historic Tables (Table 10.1), published by the
Office of Management and Budget (“OMB”). If the OMB publication is unavailable, in a written agreement not subject to Court approval under Section XVIII (Modification) of the Consent Decree, EPA and Defendant shall identify another method
to derive the inflation factor. 
 e.         Defendant shall submit the Updated Cost Estimate, in
accordance with this Paragraph, sixty (60) Days prior to the Anniversary Date of the establishment of the Financial Mechanism, except if otherwise provided herein. If more than one Financial Mechanism is being used to establish Financial
Assurance, the Updated Cost Estimate shall be submitted sixty (60) Days prior to the earliest Anniversary Date, for a given calendar year, of a Financial Mechanism. Notwithstanding the foregoing, if Defendant is establishing Financial Assurance
pursuant to Paragraph 10.a(1)(c), Defendant shall submit Updated Cost Estimate(s) pursuant to this Paragraph 4.e. as follows: (1) Updated Cost Estimate required pursuant to Paragraph 4.c. by March 31, 2017, and by March 31 every five
(5) years thereafter; and (2) Updated Cost Estimate required by Paragraph 4.a. by the end of February in 2018 and in all years thereafter except when the Updated Cost Estimate is provided under 4.e.(1), above. 

5.         Notwithstanding the provisions of Section XII (Information Collection and Retention) of the Consent Decree,
Defendant shall maintain, or have electronic access to (such that upon request the information can be readily downloaded and printed), at the Facility for the duration of this Consent Decree the Updated Cost Estimate. 

III. Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care 

6.         Within thirty (30) Days of the Effective Date of the Consent Decree or within thirty (30) Days of
EPA’s approval of Defendant’s initial Cost Estimate, whichever is later, and on the first Anniversary Date and annually thereafter, Defendant’s CFO shall provide to EPA an originally signed CFO Certification, together with supporting
documentation, confirming that it has established Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care, in an amount no less than the Total Louisiana Cost Estimate and pursuant to the requirements of either Section III.A
(Type A Financial Assurance) or Section III.B (Type B Financial Assurance), of this Appendix, at Defendant’s election. If Defendant is providing Financial Assurance pursuant to Paragraph 10.a(1)(c), Defendant’s CFO shall provide a CFO
Certification in accordance with Paragraph 29.d of this Appendix within fifteen (15) Days after such Financial Assurance has initially been provided. 

7.         Once Defendant establishes either Section III.A (Type A Financial Assurance) or Section III.B (Type B
Financial Assurance) (hereinafter also known as Section III.A or Section III.B, respectively) for Phosphogypsum Stack System Closure and Long Term Care, it shall maintain such Financial Assurance pursuant to the requirements of Section III.A or
Section III.B, as applicable, unless EPA approves a request to provide Financial Assurance pursuant to the other Section (i.e., Section III.A or Section III.B, as applicable). If Defendant wishes to request such a change in its Financial Assurance
as specified above, then Defendant shall submit to EPA for approval: (a) an originally signed CFO Certification, together with supporting documentation, explaining in detail the reasons for the request; and (b) proposed Financial
Assurance, compliant with the applicable Section III.A or Section III.B requirements, that can become effective within

written approval of Defendant’s request and the alternate Financial Assurance is in effect (e.g., trust fund is funded; insurance policy is in effect). If Defendant is providing Section III.A (Type A Financial Assurance) pursuant to Paragraph
10.a.(1)(c), a request to substitute another form of Section III.A (Type A Financial Assurance), or substitute Section III.B (Type B Financial Assurance), EPA’s approval of such a request, shall not release the Defendant from its obligation to
maintain the existing Louisiana Phosphogypsum Trust Fund. EPA’s determination whether to approve Defendant’s request to provide alternate Financial Assurance may take into account Defendant’s ability to promptly comply with the
requirements of the other of Section III. A or Section III.B, its financial stability, and other such factors and proposals as Defendant may advance in requesting the change.

(5) In addition to the requirements of LAC 33:V.3707.A and LAC 33:V.3711.A, unless the Defendant is complying with Paragraph 10.a.(1)(c) and
thus subject to Paragraph 30.g, below, Defendant shall pay all expenses incurred by the Trustee in connection with the administration of the trust fund, including reasonable fees for legal services rendered to the Trustee, and compensation of the
Trustee. 
 b.         For a surety bond guaranteeing payment or performance, Defendant shall comply

33:V.3711.B.4.c&C.4.b, such required approval by EPA shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree, but not judicial review. 

c.         For a letter of credit, Defendant shall comply with LAC 33:V.3707.D and LAC 33:V.3711.D,

comply with LAC 33:V.3707.F and LAC 33:V.3711.F, except that: 
 (1) In lieu of complying with LAC 33:V.3707.F.1.b.i and LAC
33:V.3711.F.1.b.i, Defendant shall use the current rating of either Standard & Poor’s (“S&P”) Long-Term Issuer Credit Rating or Moody’s long-term Corporate Family Rating, which assesses a company’s capacity to
meet its long-term (greater than one (1) year) financial commitments, as they come due. The rating must be BBB or greater as issued by S&P, or Baa2 or greater as issued by Moody’s. If Defendant has more than one rating, the lower of
the two will be used to meet the criteria in LAC 33:V.3707.F and LAC 33:V.3711.F. If Defendant with multiple ratings discontinues a rating that is below BBB (S&P) or Baa2 (Moody’s), or a rating agency discontinues a rating that is below BBB
(S&P) or Baa2 (Moody’s), such that the remaining rating(s) subsequently would enable the Defendant to satisfy the corporate financial test criteria, Defendant shall provide alternate Financial Assurance and shall be disqualified from using
the corporate financial test for two (2) years. 
 (2) The phrase “all Environmental Obligations” is substituted for
“current closure and post-closure cost estimates and current plugging and abandonment cost estimates” found in LAC 33:V.3707.F.1 and LAC 33:V.3711.F.1. 

(3) The term “assets” specified in LAC 33:V.3707.F.1.a.iv&b.iv and LAC 33:V.3711.F.1.a.iv&b.iv shall be replaced by the term
“tangible assets.” 
 (4) In lieu of complying with LAC 33:V.3707.F.3 and LAC 33:V.3711.F.3, Defendant shall document its
satisfaction of the corporate financial test by submitting to EPA within ninety (90) Days after the close of Defendant’s fiscal year, for each year Defendant is providing a Self-Assurance Mechanism: 

(a) A letter signed by Defendant’s CFO worded exactly as specified in Form 4-A, Attachment D of this Appendix
(“CFO Letter”). 
 (b) A copy of the independent CPA report on examination of Defendant’s audited financial
statements for the latest completed fiscal year that Defendant is using for the basis of the financial test. 
 (c) A copy of
the audited financial statements for the last completed year.

 (d) A report of procedures and findings from Defendant’s independent CPA,
resulting from an agreed-upon procedures engagement performed in accordance with the AICPA Statement on Standards for Attestation Engagements, AT Section 201 – Agreed Upon Procedures Engagements (including AICPA related
attestation interpretations), as updated, that describes the procedures performed and related findings, including whether or not differences or discrepancies were found in the comparison of financial information set out in the letter (including
attachments and exhibits) from Defendant’s CFO and Defendant’s Independently Audited, year-end financial statements for the last fiscal year, including all attachments. Where differences or discrepancies exist between Defendant’s CFO
Letter and Defendant’s Independently Audited year-end financial statements, the report of procedures and findings will reconcile any differences or discrepancies between the values or information represented in Defendant’s CFO Letter and
Defendant’s Independently Audited financial statements. Procedures to be performed by the independent CPA shall be in accordance with AT Section 201. 

(5) In addition to complying with LAC 33:V.3707.F.6 and LAC 33:V.3711.F.6, if Defendant determines at any time during the fiscal year that it
no longer meets or will not meet the requirements of this Paragraph 10.e, Defendant shall provide alternate Financial Assurance pursuant to the requirements of Section III.A (Type A Financial Assurance) and Section VII (Temporary Non-Compliance) of
this Appendix. If EPA determines that Defendant has failed to provide alternate Financial Assurance as required by this Paragraph 10.e.(5), such determination by EPA is not subject to dispute resolution pursuant to Section XI (Dispute Resolution) of
the Consent Decree, and is not subject to judicial review. 
 (6) Within thirty (30) Days of notice from EPA that EPA, pursuant to LAC
33:V.3707.F.7 and LAC 33:V.3711.F.7, no longer believes that Defendant meets the requirements of the corporate financial test criteria of Paragraph 10.e., or that EPA disallows the use of the corporate financial test based on qualifications in the
opinion expressed by the independent CPA as set out in LAC 33:V.3707.F.8 and LAC 33:V.3711.F.8, Defendant shall establish alternate Financial Assurance as required by LAC 33:V.3707.F.7&8 and LAC 33:V.3711.F.7&8 pursuant to this Section III.A
(Type A Financial Assurance). Defendant’s failure to timely establish alternate Financial Assurance is not subject to Section VII (Temporary Non-Compliance) of this Appendix. EPA’s determination to disallow the Financial Assurance provided
by the Self-assurance Mechanism based on the Defendant’s (or Defendant’s Guarantor’s) independent CPA’s adverse or disclaimer opinion based on examination of the financial statement’s shall be subject to dispute resolution
under Section XI (Dispute Resolution) of the Consent Decree, but shall not be subject to judicial review. 
 (7) In addition to complying
with LAC 33:V.3707.F and LAC 33:V.3711.F, Defendant shall: 
 (a) If more than sixty percent (60%) of
Defendant’s tangible assets are in the form of one (1) or more note receivables from one (1) or more Related Parties, submit to EPA, when providing the information required by Paragraph 10.e.(4), above, and LAC 33:V.3707.F.5 and LAC
33:V.3711.F.5, an originally signed CFO Certification together with a list of each note receivable, the name of the Related Party and a description (along with any necessary documentation) of the Related Party’s financial strength, to
demonstrate that each Related Party maintains the financial strength to meet its obligation to the Defendant.

f.         For the Corporate Guarantee, Defendant shall comply with LAC 33:V.3707.F.10 and LAC
33:V.3711.F.11, as modified by Paragraph 10.e. above, and shall meet the requirements specified below:

which it has its principal place of business; (b) Defendant submits to EPA a written legal opinion from an Independent Attorney, prior to the execution of the Guarantee, confirming that a Guarantee executed as required under this Section by the
non-U.S. Guarantor is a legally valid and an enforceable obligation in the State(s); (c) the Non-U.S. Corporation provides Independently Audited financial statements in conformance with GAAP; (d) the total amount of the Non-U.S.
Corporation’s present and proposed Guarantee’s (including self-guarantees) to cover all Environmental Obligations in the United States shall not exceed twenty-five percent (25%) of the Non-U.S. Corporation’s tangible net worth in
the United States; and (e) the written Guarantee reflects the Non-U.S. Corporation’s (Guarantor’s) agreement to comply with the reporting requirements required under the Consent Decree and that within thirty (30) Days of
executing the Guarantee the Guarantor will establish a stand-by trust with a financial institution within the continental United States, Alaska, or Hawaii. 

(2) Defendant shall use the exact wording as specified in Form 5-A, Attachment D of this Appendix, for the Corporate Guarantee. The certified
copy of the Corporate Guarantee must accompany the items sent to EPA, in accordance with Section XV (Notices) of the Consent Decree, as specified in Paragraph 10.e.(3) of this Appendix. 

11.         If Defendant seeks to provide: 

a.         More than one Third-Party Mechanism to demonstrate Financial Assurance for Phosphogypsum
Stack System Closure and Long Term Care, pursuant to LAC 33:V.3707.G and LAC 33:V.3711.G, Defendant shall submit to EPA an originally signed CFO Certification verifying that the Third-Party Mechanisms do not incorporate terms subrogating one
Financial Mechanism to another, i.e., designating a prioritization for the release of the funds or the payment of a claim. EPA, if the need arises, will determine in its unreviewable discretion the priority for the release of funds or payment of a
claim. 
 b.         A Financial Mechanism establishing Financial Assurance at more than one Facility
pursuant to LAC 33:V.3707.H and LAC 33:V.3711.H, Defendant: 
 (1) Shall not provide a single trust fund or insurance policy to cover the
multiple Facilities in different States, but shall provide each affected State with its own distinct trust fund or insurance policy; 
 (2)
May use the same letter of credit or surety bond for multiple Facilities provided that the following conditions are met: (a) the Facilities’ EPA Identification Numbers, names, addresses, and the Phosphogypsum Stack System Closure and Long

requirements of LAC 33:V.3707.A-B&D-I, LAC 33:V.3711.A-B&D-I, LAC 33:V.3717, and LAC 33:V.3719, except as clarified and modified in this Section III.B (including Attachment E). Defendant shall use the Cost Estimates generated pursuant to
Section II (Cost Estimate), above, in lieu of the cost estimates required pursuant to LAC 33:V.3705 and LAC 33:V.3709 unless otherwise directed by this Appendix, to establish Financial Assurance under this Section III.B. Defendant shall provide
Section III.B (Type B Financial Assurance) in an amount at least equal to the Total Louisiana Cost Estimate. 

13.         The options and requirements for Type B Financial Assurance depend upon Defendant’s threshold rating,
which shall be based on: (a) current S&P Long-Term Issuer Credit Rating of AAA through BB-; (b) current Moody’s Corporate Family Rating of Aaa though Ba3; or (c) an equivalent current rating from an NRSRO that assesses a
company’s capacity to meet its long-term (greater than one (1) year) financial commitments, as they come due. If Defendant has more than one rating, it shall use the lowest rating to determine its threshold rating. 

14.         A Defendant that qualifies to use a Self-Assurance Mechanism based on its threshold rating and Attachment
E shall use only one Self-Assurance Mechanism. When required under Attachment E to provide a Third-Party Mechanism in combination with a Self-Assurance Mechanism, Defendant shall use a trust fund unless permitted to substitute another type of
Third-Party Mechanism pursuant to Paragraphs 16 and 17, below. Defendant shall meet the minimum threshold amount specified in Attachment E to be funded in, or covered by, a Third-Party Mechanism. 

15.         Defendant shall use the Financial Mechanisms specified in LAC 33:V.3707.A-B&D-F and LAC
33:V.3711.A-B&D-F to establish Type B Financial Assurance as set out in Attachment E and below, provided that, if Defendant is using Third-Party Mechanisms (a trust fund, letter of credit, surety bond guaranteeing payment, or insurance), the
Trustee of any trust fund, or the provider of any letter of credit, surety bond guaranteeing payment, or insurance shall not be a Related Party to Defendant. Defendant shall word the Financial Mechanism as specified in LAC 33:V.3719, unless EPA
provides an alternate form, e.g., to address more than one beneficiary of the Financial Mechanism (i.e., EPA and the State). Defendant shall also comply with the requirements of LAC 33:V.3707.A.7-8, B.7, D.7 & E.9 and LAC 33:V.3711.A.7-8,
B.7, D.7 & E.9 , except that the corpus of the trust fund, the penal sum of the payment surety bond, the value of the letter of credit, or the limit of liability of the insurance policy shall not be reduced to reflect reductions in the Cost
Estimates until such time as the Updated Cost Estimate is equivalent to the

the requirements of LAC 33:V.3707.A.10&E.5 and LAC 33:V.3711.A.11&E.9, except as provided for in Paragraph 19 of this Appendix. If Financial Assurance is provided by multiple Third-Party Mechanisms pursuant to Paragraph 17 of this Appendix,
the individual value of the Third-Party Mechanisms shall not be reduced to reflect any reductions in the Cost Estimate until such time as the Updated Cost Estimate is equivalent to the sum of the total obligations covered by the Third-Party
Mechanisms. 
 a.         For a trust fund, Defendant shall comply with LAC 33:V.3707.A and LAC
33:V.3711.A, except that:

Defendant’s inability to immediately fund the trust fund, and including a proposal for a pay-in period of no longer than three (3) years, with at least fifty percent (50%) of the initial Cost Estimate to be funded in the first year.
Any subsequent request for an extension to an approved pay-in period shall be made at least 180 Days before the close of an approved pay-in period, and shall include an originally signed CFO Certification explaining in detail why a longer pay-in
period is needed, together with supporting documentation.

review) under Section XI (Dispute Resolution) of the Consent Decree, the surety under the terms of the bond will deposit the amount of the penal sum into the stand-by trust fund. 

(3) In the event that Defendant must provide alternate Financial Assurance pursuant to of LAC 33:V.3707.B.4.c and LAC 33:V.3711.B.4.c, such
required approval by EPA shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree, but not judicial review.

 (1) The phrase “all Environmental Obligations” is substituted for “current
closure and post-closure cost estimates and current plugging and abandonment cost estimates” found in LAC 33:V.3707.F.1 and LAC 33:V.3711.F.1. 

(2) In lieu of complying with LAC 33:V.3707.F.1.a-b and LAC 33:V.3711.F.1.a-b, Defendant shall: 

(a) Meet the corporate financial test criteria specified in Attachment E which corresponds to Defendant’s rating
threshold as specified in Paragraph 13, above. If a Defendant with multiple ratings discontinues, or S&P, Moody’s, or an NRSRO discontinues, the lower of the ratings, Defendant shall for a period of two (2) years commencing on
Defendant’s fiscal year-end apply the criteria and requirements of Attachment E (and this Paragraph) as if the lower rating were in effect. If during that two (2) year period, a change in Defendant’s other rating(s) results in
Defendant not satisfying the corporate financial test or becoming subject to a more stringent set of corporate financial test criteria under Attachment E, Defendant shall provide Financial Assurance as specified in Paragraphs 15.e.(4)(a) and 18.

 (b) Calculate the three (3)-year rolling average specified in Attachment E for the Debt-to-Equity Ratio (TL/NW), Current
Ratio, or the Operating Cash Flow metric (“OCF metric”) as follows: (i) TL/NW is a three (3)-year rolling average of total liabilities divided by three (3)-year rolling average of net worth; (ii) CA/CL is a three (3)-year rolling

33:V.3707.F.3 and LAC 33:V.3711.F.3, Defendant shall document its satisfaction of the corporate financial test by submitting to EPA within ninety (90) Days after the close of Defendant’s fiscal year, for each year Defendant is providing a
Self-Assurance Mechanism:

Defendant’s independent CPA, resulting from an agreed-upon procedures engagement performed in accordance with the AICPA Statement on Standards for Attestation Engagements, AT Section 201 - Agreed Upon Procedures Engagements
(including AICPA related attestation interpretations), as updated, that describes the procedures performed and related findings, including whether or not differences or discrepancies were found in the comparison of financial information set out in
the letter (including attachments and exhibits) from Defendant’s CFO and Defendant’s Independently Audited, year-end financial statements for the last fiscal year, including all attachments. Where differences or discrepancies exist between
Defendant’s CFO Letter and Defendant’s Independently Audited year-end financial statements, the report of procedures and findings will reconcile any differences or discrepancies between 

  
 21 

Mosaic Appendix 2

the values or information represented in Defendant’s CFO Letter and Defendant’s Independently Audited financial statements. Procedures to be performed by the independent CPA shall be in
accordance with AT Section 201. 
 (4) In addition to complying with LAC 33:V.3707.F.6 and LAC 33:V.3711.F.6, if Defendant determines
at any time during the fiscal year that: 
 (a) It no longer meets or will not meet the requirements of this Paragraph
15.e. (including the loss of a threshold rating except as provided by Paragraph 15.e.(2)(a), above), Defendant shall within ten (10) Days send written notice to EPA of this determination, by certified mail, stating the basis for such a
determination. If Defendant cannot re-establish compliance with the requirements of this Paragraph 15.e. pursuant to Section VII (Temporary Non-Compliance) and/or Section VIII.B (Compliance Schedule: Type B) of this Appendix, the Defendant, within
thirty (30) Days of its notice to EPA as specified above, shall provide alternate Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care pursuant to Paragraph 18, below. 

(b) Its threshold rating requires Defendant to change from one set of corporate financial test criteria under Paragraph
15.e.(2), above, and Attachment E (e.g., CFT Criteria A) to a more stringent set of corporate financial test criteria (e.g., CFT Criteria C), Defendant shall notify EPA within ten (10) Days of the change in corporate financial test criteria and
within thirty (30) Days of such notice shall submit to EPA a revised corporate financial test or Corporate Guarantee based on the most recent evaluation conducted under Paragraph 15.e.(6)(c), below, demonstrating compliance with the more
stringent corporate financial test criteria. To the extent necessary, Defendant shall at the same time make a contribution to the Third-Party Mechanism to comply with the minimum threshold amount specified in the corporate financial test
requirements in Paragraph 15.e.(2), above. 
 (c) If EPA determines that Defendant has failed to provide alternate Financial
Assurance as required, or complied with Paragraphs 15.e.(4)(a) and (4)(b), such determination by EPA is not subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree, and is not subject to judicial review. 

(5) Within thirty (30) Days of notice by EPA that EPA, pursuant to LAC 33:V.3707.F.7 and LAC 33:V.3711.F.7, no longer believes that

33:V.3707.F.8 and LAC 33:V.3711.F.8, Defendant shall provide alternate Financial Assurance as required by LAC 33:V.3707.F.7&8 and LAC 33:V.3711.F.7&8 pursuant to Paragraph 18 of this Appendix. Defendant’s failure to timely provide
alternate Financial Assurance is not subject to Section VII (Temporary Non-Compliance) of this Appendix. EPA’s determination to disallow the Financial Assurance provided by the Self-Assurance Mechanism based on the Defendant’s (or
Defendant’s Guarantor’s) independent CPA’s adverse or disclaimer opinion based on examination of the financial statement’s shall be subject to dispute resolution under Section XI (Dispute Resolution) of the Consent Decree, but is
not subject to judicial review. 
 (6) In addition to complying with LAC 33:V.3707.F and LAC 33:V.3711.F, Defendant shall: 

(a) If Defendant with an S&P rating of BB-, Moody’s rating of Ba3, or an equivalent NRSRO rating, receives a
negative outlook posted on one or more of its ratings, or receives a qualified opinion from an independent CPA, or is delisted from an Exchange

for any reason other than: (i) Defendant’s decision to take the company into private ownership, or (ii) a transaction which results in the acquisition of Defendant (or
Defendant’s ultimate parent corporation) by another company subjecting Defendant to Section X (Business Transactions) of this Appendix, then Defendant shall within ten (10) Days of such an event send written notice by certified mail of
such event to EPA, and within thirty (30) Days of such notice shall provide an alternate form of Financial Assurance, in compliance with Paragraph 18 of this Appendix. In the event that the delisting is due to Defendant’s decision to take
the company into private ownership Defendant may continue to provide Financial Assurance using the Financial Mechanism(s) already in place if, within twenty (20) Days of the delisting, it provides documentation to EPA from S&P, Moody’s
or the NRSRO confirming that Defendant meets a current S&P Long-Term Issuer Credit Rating, Moody’s long-term Corporate Family Rating, or equivalent current rating from an NRSRO, as specified in Paragraph 13 of this Appendix. 

(b) If more than sixty percent (60%) of Defendant’s tangible assets are in the form of one (1) or more note
receivables from one (1) or more Related Parties, submit to EPA, when providing the information required by Paragraph 15.e.(3), above, and LAC 33:V.3707.F.5 and LAC 33:V.3711.F.5, an originally signed CFO Certification by the Defendant’s
CFO together with a list of each note receivable, the name of the Related Party and a description (along with any necessary documentation) of the Related Party’s financial strength, to demonstrate that each Related Party maintains the financial
strength to meet its obligation to the Defendant. 
 (c) On a quarterly basis prepare and use financial statements (including
balance sheets, income statements, and cash flow statements), reviewed by an independent CPA, to evaluate Defendant’s ability to meet the criteria of the corporate financial test. To meet the criteria involving rolling averages, the averages
shall be based on the results as of the end of the same quarter for the prior years (i.e., a three (3)-year rolling average evaluated at the end of the first quarter for Year X shall include the results from
the first quarter of Year X-2 and X-1). In addition, Operating Cash Flow for this evaluation shall be based on the results from the most recent four (4) quarters (i.e., for a first quarter analysis, the Operating Cash Flow shall be based on the
results from the second quarter of the previous year through the first quarter of the current year). The same adjustment shall be made for the OCF metric for prior periods if the criteria involve the use of a rolling average. 

(d) If Defendant with a S&P rating of BBB- through BB, a Moody’s rating of Baa3 through Ba2, or an equivalent rating
from an NRSRO receives a negative outlook posted on one or more of its ratings, or receives a qualified opinion rendered by an independent CPA, Defendant within twenty (20) Days of such event shall submit to EPA a revised corporate financial
test based on the most recent evaluation conducted under Paragraph 15.e.(6)(c), above. 

f.        For the Corporate Guarantee, Defendant shall comply with LAC 33:V.3707.F.10 and LAC
33:V.3711.F.11, and shall meet the requirements specified below, if applicable. 
 (1) Defendant may use a Non-U.S. Corporation as a
Guarantor only if the following conditions are met: (a) Non-U.S. Corporation meets the requirements of Paragraph 10.f. of this Appendix, and (b) Non-U.S. Corporation has a current rating for either the S&P long-term issuer credit
rating of AAA through BBB, Moody’s long-term corporate family rating of Aaa though

Baa2 or an equivalent rating from an NRSRO that assesses a company’s capacity to meet its long-term (greater than one (1) year) financial commitments, as they come due. 

(2) Defendant shall use the exact wording as specified in Form 5-A, Attachment D of this Appendix, for the Corporate Guarantee. The certified
copy of the Corporate Guarantee must accompany the items sent to EPA, in accordance with Section XV (Notices) of the Consent Decree, as specified in Paragraph 15.e.(3) of this Appendix. 

16.        Defendant may submit annually, for EPA approval, a request to use a letter of credit, surety bond
guaranteeing payment, or insurance in lieu of the trust find required under Paragraph 14, above. Defendant shall include in its request documentation demonstrating compliance with Financial Assurance under this Subsection III.B. Defendant may not
rely upon the letter of credit, payment surety bond, or insurance to establish compliance with this Appendix until EPA has approved the Third-Party Mechanism. Defendant shall comply with the letter of credit, payment surety bond, or insurance
requirements of Paragraph 15 of this Appendix, as applicable. Defendant shall also demonstrate compliance with Paragraph 11 of this Appendix. EPA’s determination whether or not to accept Defendant’s request is subject to dispute resolution
pursuant to Section XI (Dispute Resolution) of the Consent Decree, but is not subject to judicial review. 

17.        Defendant may submit annually, for EPA approval, a request to use multiple Third-Party Mechanisms (i.e.,
trust fund, letter of credit, surety bond guaranteeing payment, and insurance) in conjunction with a Self-Assurance Mechanism, together with supporting documentation, to demonstrate Financial Assurance for Phosphogypsum Stack System Closure and Long
Term Care. Defendant shall not rely upon the additional Third-Party Mechanism to establish compliance with this Consent Decree until EPA has approved the additional Third-Party Mechanism. Defendant shall also demonstrate compliance with Paragraph 11
of this Appendix. EPA’s determination whether or not to accept Defendant’s request is subject to dispute resolution under Section XI (Dispute Resolution) of the Consent Decree, but is not subject to judicial review. 

18.        If Defendant at any time becomes ineligible to rely on a Self-Assurance Mechanism pursuant to this Section
III.B, and cannot re-establish such eligibility pursuant to Section VII (Temporary Non-Compliance) and/or Section VIII.B (Compliance Schedule: Type B) of this Appendix, then Defendant shall establish alternate Financial Assurance based on Current
Dollars by: (a) maintaining the existing Financial Assurance in the trust fund (or as approved, other Third-Party Mechanism) as established pursuant to Paragraph 14; (b) providing additional Financial Assurance using Third-Party
Mechanism(s) pursuant to Paragraphs 10.a-d, except for Paragraph 10.a.(1)(c); and (c) meeting the requirements of Paragraph 11 of this Appendix when providing more than one Financial Mechanism. If Defendant meets the above requirements and EPA
approves the alternate Financial Assurance (including the termination of a Corporate Guarantee if provided), Defendant does not need to meet the requirements of Paragraph 15 of this Appendix. Defendant shall continue to be subject to Section III.B
(Type B Financial Assurance), as set forth in this Paragraph 18, unless EPA approves a request to change to Section III.A (Type A Financial Assurance) pursuant to Paragraph 6 of this Appendix.

 19.        If the Total Louisiana Cost Estimate at the commencement of
Defendant’s fiscal year is less than or equal to the value of the following Third-Party Mechanism(s), trust fund or insurance, then Defendant, may draw upon the Third-Party Mechanism(s) to pay for Phosphogypsum Stack System Closure and Long
Term Care. Otherwise, Defendant shall first draw upon the resources of the Self-Assurance Mechanism before drawing upon a Third-Party Mechanism to pay for Phosphogypsum Stack System Closure or Long Term Care. If EPA approves the use of multiple
Third-Party Mechanisms under Paragraph 17, above, EPA will designate the priority for drawing on the Third-Party Mechanisms and EPA’s designation shall not be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the
Consent Decree, and shall not be subject to judicial review. 
 IV. Financial Assurance for Corrective Action

this Appendix as applied to the Plan Work. 
 22.        Within thirty (30) Days of receiving written approval
by EPA of any Corrective Action Plan required pursuant to Paragraph 18 of Attachment A of Appendix 1 of the Consent Decree, or any corrective action assessment by EPA for the Zone of Discharge required pursuant to Section D of Attachment B of
Appendix 1 of the Consent Decree, Defendant shall submit to EPA for approval a proposed Financial Assurance Plan to implement the applicable Plan Work. The proposed Financial Assurance Plan shall include, as appropriate:

Assurance, wishes to provide Financial Assurance in phases corresponding to the estimated costs for each stage of Plan Work or wishes to seek a waiver of all or part of the Financial Assurance required under this Section IV, Defendant shall submit a
request to EPA explaining the basis for the proposed alternate, reduced or phased Financial Assurance, or the waiver of all or part of the Financial Assurance, together with supporting documentation, for approval. 

c.        A proposed schedule (on at least a semi-annual basis) to update the Corrective Action Cost
Estimate pursuant to Paragraph 22.b., above, to reflect inflationary adjustments and/or changes to the Plan Work. 

23.        Within thirty (30) Days of EPA’s approval of Defendant’s Financial Assurance Plan, Defendant
shall provide Financial Assurance for the Plan Work in an amount no less than the approved Corrective Action Cost Estimate, and in accordance with the Financial Assurance Plan approved by EPA.

schedules set forth in Paragraph 25, provide the Financial Mechanism and information required for Third Party Liability in accordance with the schedule and deadlines in Paragraph 29.d. The Financial Assurance for Third Party Liability shall comply
with LAC 33:V.3715, except as provided in Paragraph 25, below, and in lieu of complying with LAC 33:V.3715.E Defendant shall maintain such Financial Assurance for the duration of Phosphogypsum Stack System Closure or Long Term Care. If Defendant
wishes to propose an adjustment to the amount of Financial Assurance pursuant to LAC 33:V.3715.C, Defendant shall submit to EPA for approval an originally signed CFO Certification and, as set forth in LAC 33:V.3715.C, explaining the basis for the
proposed adjustment, together with supporting documentation. Until such time as EPA approves the adjusted Financial Assurance in writing, Defendant shall provide Financial Assurance for Third Party Liability as required herein. Nothing in this
Paragraph shall be construed to waive or limit EPA’s right, pursuant to LAC 33:V.3715.D, to adjust the level of Financial Assurance required in LAC 33:V.3715.A&B. EPA’s determination of whether or not to approve Defendant’s
request under LAC 33:V.3715.C is subject to dispute resolution under Section XI (Dispute Resolution) of the Consent Decree, but not judicial review. 

25.        Defendant’s Financial Assurance for Third Party Liability shall comply with LAC 33:V.3715.A-B&F-J, and LAC 33:V.3719.G,H.2 & I-N, except as otherwise provided in the F.A.C., and as modified by this Paragraph. If Defendant is using a trust

31.j. through 31.m., and Defendant requests additional time to secure and provide alternate Financial Assurance under Paragraphs 31.j. through 31.m., Defendant shall submit to EPA for approval a plan and schedule for providing such alternate
Financial Assurance. Such plan may include the continued role of the Guarantor under a Corporate Guarantee. 
 (1) The proposed plan and

Financial Assurance. Such certification shall be required annually, and submitted along with the information provided under the Corporate Guarantee. 

(3) EPA’s determination of whether or not to approve Defendant’s plan and schedule for providing alternate Financial Assurance, as
required by Paragraphs 31.j, 31.l, and 31.k for an EPA decision based on an independent CPA’s adverse or qualified opinion, is subject to dispute resolution under Section XI (Dispute Resolution) of the Consent Decree, including judicial review
except that Defendant shall seek any such judicial review in Court within seven (7) Days after the conclusion of the dispute resolution period, and the position of EPA shall become effective unless stayed or modified by the Court within twenty
(20) Days of the conclusion of the dispute resolution period. EPA’s determination of whether or not to approve Defendant’s plan and schedule for providing alternate Financial Assurance as required by Paragraphs 31.k. (except for EPA

 A.        Type A Financial
Assurance 
 29.        In the event that the Defendant establishes Financial Assurance pursuant to Section
III.A (Type A Financial Assurance), Paragraph 10.a.(1)(c), Defendant shall meet the following: 

a.        Defendant shall: 

(1) Deposit $113.696 Million into a trust fund (“Louisiana Phosphogypsum Trust Fund”) that shall be set up in accordance with
Paragraph 30, below, for the Phosphogypsum Stack System Closure of the Operating Facility and for the Long Term Care at the Operating and Closing Facilities no later than thirty (30) Days after the Effective Date of the Consent Decree or by
January 11, 2016, whichever is later; and 
 (2) Provide an executed Corporate Guarantee, in accordance with Paragraph 31, below, in
the amount represented by the Louisiana Financial Assurance Delta. The signed Guarantee is attachment to this Appendix (Attachment I) and will be in effect as of the Effective Date of the Consent Decree. 

b.        For each Facility: 

(1) Financial Assurance provided by Defendant pursuant to this Section VIII.A shall apply only to and shall satisfy all requirements
concerning Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care under this Consent Decree with respect to: 

(a) The current configuration of the Phosphogypsum Stack System at the Operating and Closing, as reflected in Attachment F,
Exhibit F-1 (i.e., existing Phosphogypsum Stack System), including any increase in height within that configuration and its current footprint up to its design height, and 

(b) Any planned lateral expansion(s) of the existing Phosphogypsum Stack System at the Operating Facilities as identified by
the Defendant in 2015 (i.e., Attachment F, Exhibit F-2, and identified in Attachment G: Baseline as “Planned Future Expansion Closure Area”) (“Planned Expansion”): (i) that qualifies as a “Covered Expansion” under
Paragraph 29.b.(2) below, and (ii) that becomes part of the Phosphogypsum Stack System configuration (i.e., fully-engineered and constructed) upon and in accordance with any requisite approvals by LDEQ pursuant to the laws and regulations of
Louisiana. Nothing in this Paragraph or in the Consent Decree shall be construed to limit, alter or supersede the permitting and approval authorities of LDEQ with respect to the permitting or timing and conditions of the Planned Expansion(s). 

(2) The Planned Expansion(s) shall be a Covered Expansion if it meets either of the following criteria, below, to be determined at the time
the Planned Expansion(s) is fully engineered and the information required by Paragraph 29.b.(3), below, has been submitted (the “Determination Date”): 

(a) The Total Phosphogypsum Volume3 in the Phosphogypsum Stack System
anticipated at the Determination Date (calculated pursuant to Paragraph 29.b.(3), below) is not more than two point five percent (2.5%) greater than the Total Phosphogypsum Volume anticipated in 2015 (as specified in the Attachment G:
Baseline), and the 
  
 3 Total Phosphogypsum Volume is utilized herein as an approximate surrogate for pore water volume. 

  
 30 

Mosaic Appendix 2 

Table of Contents

 
anticipated Total Future Closure Area at the Determination Date (calculated pursuant to Paragraph 29.b.(3), below) is not more than three percent (3%) greater than the Total Future Closure
Area anticipated in 2015 (as specified in Attachment G: Baseline); or 
 (b) The sum of the following is not more than
five percent (5%): 
     (i) The percent (%) change between the Total Phosphogypsum Volume
anticipated at the Determination Date (calculated pursuant to Paragraph 29.b.(3), below) and the Total Phosphogypsum Volume anticipated in 2015 (as specified in the Attachment G: Baseline), and 

    (ii) The percent (%) change between the Total Future Closure Area anticipated at the
Determination Date (calculated pursuant to Paragraph 29.b.(3), below) and the Total Future Closure Area anticipated in 2015 (as specified in the Attachment G: Baseline). 

(c) Defendant shall, in making the calculations required by Paragraph 29.b.(2)(b), above, substitute zero (“0”) for a
negative percentage that may be generated when comparing the Total Phosphate Volume or the Total Future Closure Area as of the Determination Date to the 2015 baseline. 

(3) Defendant shall submit to EPA information regarding the Planned Expansion(s) at the Operating Facility as follows: 

(a) If Defendant has not provided the information regarding the Planned Expansion(s) at the Operating Facility identified
by Defendant in 2015, using the form in Attachment G, prior to the Effective Date of the Consent Decree, then Defendant shall submit such information to EPA (the “Attachment G: Baseline”) within thirty (30) Days of the Effective Date
of the Consent Decree to use as a baseline in determining if the Planned Expansion(s) once fully engineered is a Covered Expansion. 

(b) Defendant shall submit updated information regarding the Planned Expansion using the form in Attachment G (the
“Attachment G: Updated”), within 45 (forty-five) Days of the time that a Planned Expansion has been fully-engineered. The information submitted shall be used to determine if the Planned Expansion as fully engineered is a Covered Expansion.
Attachment G: Updated shall include the following adjustments, if applicable: 
 (i) If Defendant has not installed a liner
as identified in the 2015 baseline as reflected in Attachment G: Baseline at the corresponding average stack elevation prior to activation of the Planned Expansion, then the Total Phosphogypsum Volume shall be revised in the Attachment G: Updated to
account for the lack of the liner by adding in the corresponding values of phosphogypsum volume deducted for that anticipated liner as previously calculated and reflected in the Attachment G: Baseline in the column labelled “Phosphogypsum
Volume to be Added if Proposed HDPE Liner is Not Installed at Elevation 100’(acre-feet).” 
 (ii) If Defendant
has, after 2015, either lined or closed an isolated section of the Phosphogypsum Stack System or has installed a liner for such section that had not been identified in the 2015 Attachment G, the volume of phosphogypsum beneath the liner at the time
of liner installation may be reduced at the rate of eight percent (8%) annually for the period following the installation of the liner until the Determination Date, when calculating the Total Phosphogypsum Volume on the Updated Attachment G.

 (iii) If Defendant, after 2015, closes a portion of the stack top area or slope
area earlier than scheduled to be closed, the corresponding area(s) may be deducted from the Total Future Closure Area in the Updated Attachment G, provided there are no then-planned lateral or vertical expansions that would require re-activating
the closed areas. 
 (4) Notwithstanding the adjustments in Paragraph 29.b.(3)(b), above, a Planned Expansion shall not be considered a
Covered Expansion if the total area of the Planned Expansion as fully engineered exceeds the area of the Planned Expansion as specified in Attachment F (Figure F-2) and the Attachment G: Baseline (i.e., “Future Expansion Closure Area”) by
more than eight percent (8%). 
 (5) Defendant shall provide financial assurance under applicable State law and regulations for: 

(a) Any new Phosphogypsum Stack, new Phosphogypsum Stack System, or new expansion of a Phosphogypsum Stack System (i.e., any
lateral expansions, increased height above the design height as of 2015, new cooling pond or other form of expansion, in each case to the extent not identified in Attachment F); and 

(b) A Planned Expansion that exceeds the criteria for a Covered Expansion. The financial assurance shall be in an amount equal
to the difference in the (i) costs of Phosphogypsum Stack System Closure and Long Term Care between the Planned Expansion as anticipated in 2015 (see Attachment G: Baseline, “Planned Future Expansion Closure Area” and
“Planned Future Expansion Phosphogypsum Volume”) for the Operating Facility and (ii) and the fully-engineered, actual build of the Planned Expansion, as permitted by LDEQ, and as reflected in Attachment G: Updated (i.e.,
“Expansion Closure Area” and “Expansion Phosphogypsum Volume”). This financial assurance, unless otherwise agreed to by LDEQ in its sole discretion, is due within ninety (90) Days of submitting the Attachment G: Update. 

(6) Defendant shall not use the Financial Mechanisms demonstrating Financial Assurance under this Consent Decree (e.g., Financial Mechanisms
specified in Paragraph 29.a. of this Appendix) or that may be required in Paragraphs 27 or 31 of this Appendix, in establishing or demonstrating compliance with any financial assurance required pursuant to any federal or State law or regulations.
Defendant is not precluded from relying on such Financial Mechanisms in satisfying any financial metric or test utilized for financial assurance when permitted under a federal or State law or regulation. 

(7) Defendant shall archive and maintain the Computer Aided Design (“CAD”) files, for the Operating Facility, which contain the
underlying information for the values specified in Attachment G: Baseline. Defendant shall maintain the CAD files until Phosphogypsum Stack System Closure and Long Term Care, pursuant to a Permanent Closure Plan, has been implemented at the New
Wales Facility. Defendant shall provide access to the CAD files, or provide the CAD files, within thirty (30) Days of the EPA’s request. 

c.        Defendant shall first draw upon its own resources or a Guarantor’s resources (as set
forth in Paragraph 31), before requesting any reimbursement or release from the Louisiana Phosphogypsum Trust Fund or any other Third-Party Mechanism established pursuant to this Section VIII to pay for the Phosphogypsum Stack System Closure and/or
Long Term Care at the Operating and Closing Facilities. If EPA approves additional Third-Party Mechanisms, as set out in Section III.A (Type A Financial Assurance) of this Appendix (e.g., insurance), EPA will

determine the priority for drawing on the Third-Party Mechanisms and such determination is not subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree and
is not subject to judicial review. 
 d.        Within forty five (45) Days of the trust fund
being established and funded as set forth in Paragraph 29.a., above, or by March 31 of the calendar year in which the trust fund is established and funded, whichever is later, and on or before the Anniversary Date in the following calendar year
and annually thereafter, Defendant shall provide to EPA an originally signed CFO Certification in the form attached hereto as Attachment A from the Defendant’s CFO together with supporting documentation, confirming that it has established
Financial Assurance for Phosphogypsum Stack System Closure and Long Term Care at the Operating and Closing Facilities in a total amount no less than the Total Louisiana Cost Estimate. The Anniversary Date under this Section XVIII.A. of the Appendix

the Third-Party Mechanism by twenty-five percent (25%). If Defendant can satisfy the corporate financial test criteria by the fiscal year-end (i.e., in its annual submission pursuant to Paragraph 15.e.(3), above) and Defendant’s quarterly
review under Paragraph 15.e.(6)(b) for the following fiscal year does not result in notification from Defendant that it does not satisfy the corporate financial test, Defendant can request and EPA will authorize the release of funds or a reduction
in the value of the Third-Party Mechanism commensurate with the contemporaneous Cost Estimate and requirements of Paragraph 15.e. of this Appendix. 

b.         If Defendant fails to satisfy the corporate financial test criteria and requirements of
Paragraph 15.e., above, for any two (2) consecutive quarters in a given fiscal year (not including the fourth quarter (i.e., fiscal year-end)), Defendant shall provide alternate Financial Assurance in accordance with Paragraph 18 of this
Appendix. If Defendant can satisfy the corporate financial test criteria by the fiscal year-end (i.e., in its annual submission pursuant to Paragraph 15.e.(3)) and its annual submissions pursuant to Paragraph 15.e.(3), above, for the following two
(2) fiscal years do not trigger Paragraphs 15.e.(4) or 15.e.(5), above, EPA upon Defendant’s request will authorize a release of the funds or a reduction in the value of the Third-Party Mechanism(s) so that the value of the Third-Party
Mechanism is commensurate with the minimum threshold funding for a Third-Party Mechanism as specified in Attachment E plus an additional twenty-five percent (25%) of the Cost Estimate. 

c.          Defendant shall be deemed to be without Financial Assurance for purposes of enforcement
(but not for accessing or collecting Financial Assurance should it be necessary) if Defendant fails to meet a compliance schedule. Failure to timely comply with a compliance schedule or to provide alternate Financial Assurance pursuant to this
Section VIII.B (Compliance Schedule: Type B Financial Assurance) is not subject to the provisions of Section VII (Temporary Non-Compliance) of this Appendix. 

IX. Business Transactions 

33.         No transfer of ownership or operation of a Facility shall relieve Defendant of its Financial Assurance
obligations under this Consent Decree, except as provided by this Section X (Force Majeure) and Section II (Applicability) of the Consent Decree. 

34.         At least thirty (30) Days prior to any transfer, Defendant shall submit to EPA information explaining
the proposed transfer in detail and stating whether Defendant requests the transfer of its Financial Assurance responsibilities to the Transferee pursuant to Section II (Applicability) of the Consent Decree and Paragraph 35.b, below. 

35.         In the event of a transfer of a Facility’s ownership or operation: 

a.         If Defendant is to retain its Financial Assurance obligations upon the transfer of the
Facility, Defendant, based on a Cost Estimate in Current Dollars, shall establish and fund a trust fund, or obtain a surety bond or letter of credit in accordance with this Appendix. Any 

  
 42 

Mosaic Appendix 2 

Table of Contents

 
existing trust fund established pursuant to Paragraph 10.a.(1)(c) shall remain in place. Defendant shall provide EPA the appropriate documentation evidencing the trust fund, surety bond, or
letter of credit by the date of the Facility transfer. If using a trust fund, the portion of funds vested in the trust fund that are not required to meet annual withdrawals shall be invested in U.S. Treasury Bills, or market-based notes and bills
that achieve an investment goal or preservation of principle and guarantee an inflation-adjusted rate of return no less than the 30-Year Treasury Constant Maturity Rate average for the previous twelve (12) months from the date of the annual
Cost Estimate. If Defendant wishes to propose alternate Financial Mechanism(s) in lieu of the trust fund, surety bond, or letter of credit, Defendant at least thirty (30) Days prior to the transfer shall submit an originally signed CFO
Certification from the Defendant’s CFO, together with supporting documentation, explaining the compelling reasons why the proposed alternate Financial Mechanism is being requested and is an equivalent substitute for the trust fund, surety bond,
or letter of credit. Upon EPA’s approval, which shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of the Consent Decree but shall not be subject to judicial review, Defendant shall establish the approved
Financial Assurance. If by the date of the transfer, EPA does not approve such a request or the Defendant has not put in place the approved Financial Assurance, then Defendant shall fully fund the trust fund or obtain a surety bond or letter of
credit, as described above. 
 b.         If Transferee agrees to assume Defendant’s Financial
Assurance obligations, Defendant shall submit to EPA for approval an originally signed certification by Transferee’s CFO, together with supporting documentation, explaining in detail its ability to provide Financial Assurance pursuant to the
requirements of this Appendix (except for Paragraph 10.a.(1)(c)) and agreeing to provide the Financial Assurance if approved by EPA pursuant to Section II (Applicability) of the Consent Decree. Defendant shall comply with the requirements of
Paragraph 35.a., above, until: (1) EPA has approved Transferee’s proposed Financial Assurance; (2) the United States, after consultation with Louisiana, consents to the transfer of obligations pursuant to Section II (Applicability) of
the Consent Decree; (3) Transferee has established the approved Financial Assurance; and (4) EPA has given its consent for Defendant to terminate its Financial Assurance. If Defendant is providing Financial Assurance pursuant to Paragraph
10.a.(1)(c) of this Appendix, and if the Transferee is acquiring all of the Defendant’s Operating and Closing Facilities in Louisiana, then the Louisiana Phosphogypsum Trust Fund (see Paragraph 30.b), and if still in existence,
the required Guarantee (see Paragraph 31.c) and the required letter of credit, will be the Financial Assurance subject to Paragraph 35.b.(4) that may be terminated. 

36.         If Defendant is providing Financial Assurance through the use of any Financial Mechanism other than the
exclusive use of a fully funded trust fund in Current Dollars, in the event of a business transaction that results, or Defendant determines will result, in an adverse material change to Defendant’s financial or corporate structure such that
Defendant or its successor (or a Guarantor of Defendant or its successor) has insufficient operating cash flow or Tangible Assets to cover the long-term (greater than one (1) year) financial liabilities as represented on the Defendant’s or
successor’s audited balance sheet and to comply with the Financial Assurance requirements of this Consent Decree, Defendant shall provide notice to EPA within fourteen (14) Days of identifying such adverse material change and comply with
the requirements for Financial Assurance in Paragraph 35.a., above.

 37.         If Defendant becomes a private company, Defendant shall
provide, in addition to the CFO Letter in Attachment D (Forms 4), a full accounting of its financial condition and a certification from the CFO that the Defendant expects to have sufficient operating cash flow or Tangible Assets located in the
United States to cover long-term (greater than one (1) year) financial liabilities as represented in the audited financial statements and to comply with the Financial Assurance requirements of this Consent Decree Defendant shall make such a
certification as long as Defendant provides a Self-Assurance Mechanism a part of its Financial Assurance. 
 X. Reservation of Rights 

38.         If EPA determines at any time that the Financial Assurance provided by Defendant no longer satisfies the
requirements of this Consent Decree, it shall notify Defendant. EPA may base this determination on Defendant’s failure to provide notices or documentation required by this Appendix as well as on a substantive evaluation of Defendant’s
Financial Assurance. Within thirty (30) Days of written notice from EPA that Defendant’s Financial Assurance no longer satisfies the requirements of this Consent Decree, Defendant shall submit to EPA for approval revised or alternate
Financial Assurance that satisfies the requirements of this Consent Decree. Defendant shall not cancel the existing Financial Assurance until the revised or alternate Financial Assurance has been approved by EPA and EPA has provided written consent
permitting Defendant to cancel the existing Financial Assurance. Failure to timely provide alternative Financial Assurance as required by this Section (or any Paragraph of this Appendix that references this Section) is not subject to the provisions
of Section VII of this Appendix. EPA’s determination shall be subject to dispute resolution pursuant to Section XI (Dispute Resolution) of this Consent Decree, but not judicial review, and the time frames for notices and submissions under the
dispute resolution process shall be reduced by half (e.g., under Informal Dispute Resolution Defendant shall submit its Notice of Dispute within fifteen (15) Days). In the event that Defendant is providing Financial Assurance pursuant to
Paragraph 10.a.(1)(c), and there is a conflict between this Paragraph 38 and Paragraph 31, then the provisions of Paragraph 31 shall control, except that the time frames for notices and submissions under Section XI (Dispute Resolution) of this
Consent Decree shall be reduced by half unless otherwise specified in Paragraph 31 of this Appendix.

 II.         COST ESTIMATE ADJUSTMENT 

Please check below the appropriate boxes identifying the type of Cost Estimate adjustment under this Section. In addition, Defendant shall complete Attachments B-1 and,
if needed, Attachments B-2 and B-3, unless providing Financial Assurance pursuant to Paragraph 10.a.(1)(c) of Appendix 2, in which case Defendant need not provide Attachments B-2 and B-3 and need only provide Attachment B-1 when providing the
Updated Cost Estimate pursuant 

  
 Mosaic 

Appendix 2, Attachment B

 to Paragraph 4.c.(2). Requirements under the Consent Decree for Cost Estimate are found in Appendix 2, Section II, of the
Consent Decree. 

 ̈  
       A.         Inflation Adjustment to Cost Estimate 
 The Cost Estimate
may be adjusted for inflation by using an inflation factor. Please follow the instructions below in each subsection to derive the inflation factor that must be used when adjusting the Cost Estimate for inflation. If providing Financial Assurance
pursuant to Appendix 2, Subsection III.A, of the Consent Decree, complete subsections A(1)-(2), below. If providing Financial Assurance pursuant to Appendix 2, Subsection III.B of the Consent Decree, complete subsections A(1) & (3), below.
Use of an inflation factor may only occur when there is a Phosphogypsum Stack System Closure and Long Term Care Cost Estimate and a periodic re-evaluation of the Cost Estimate is not required under Section II of Appendix 2 (e.g., Paragraph 4.c.).

 Inflation Factor 
 When adjusting for inflation to
update the current dollar Cost Estimate in subsection A(1) and A(2), below, the inflation factor must be derived from the most recent Implicit Price Deflator for Gross National Product (“Deflator”) published by the U.S. Department of
Commerce in its Survey of Current Business. The inflation factor is the result of dividing the latest published annual Deflator by the Deflator in effect at the time of the latest current dollar Cost Estimate. Attachment B, Exhibit 1 provides
information (and examples) to use when deriving the imputed deflators for the annual inflationary adjustments under Appendix 2. See also Appendix 2, Paragraphs 4.a.(1) and 4.a.(2), of the Consent Decree. (For additional information and
guidance see 40 C.F.R. §§ 264.142(b)(1)&(2) and 264.144(b)(1)&(2).)

update the Long Term Care Cost Estimate for inflation, complete the following steps as instructed and place the information in the line items designated below: 
  

	 	(i)	To determine the Long Term Care and associated Water Management Costs in Current Dollars, calculate the costs as instructed in subsection A(2), above, filling in the necessary information. 

	 	(ii)	To inflate forward the current Long Term Care and associated Water Management costs for all remaining years of Long Term Care, adjust the costs as instructed in Attachment B-2, adjusting each year’s costs by the
inflation factor specified in Attachment B-2. (For additional reference information, see Paragraph 4.d., Appendix 2, of the Consent Decree.) 

	 	(iii)	Using each year’s adjusted costs due to inflation, place the information from Attachment B-2 in the corresponding line items located in Attachment B-3. 

	 	(iv)	 Following the instructions for Attachment B-3 to determine the present value of Long Term Care and associated Water Management costs for each year. To derive the
net present value dollars for inflation adjusted Long Term Care, add each year’s present value for Long Term Care costs; to

 This example assumes that the latest published quarterly deflator is Q2 2013. Because there are only two quarters with
published deflators in Column (B), the values in Column (C) and Column (D) are the same. The value in Cell D2 is added to Cell B2 to derive the imputed deflator for Q3 2013 (see Cell E3). To derive the imputed deflator for Q4 2013, the
value in Cell D2, is added to imputed deflator for Q3 2013 (Cell E3) to derive the imputed deflator for Q4 2013 (Cell E4).

 Attachment B-1: Instructions 

Attachment B-1 (and associated Forms 1-3) provides a framework that summarizes the types of activity, quantity (or volume), and costs
associated Phosphogypsum Stack System Closure (Form 1), Long Term Care (Form 2) and the associated Water Management activities (Form 3). The information to be captured in the Exhibits and submitted in accordance with Section II (Cost Estimate),
Appendix 2 of the Consent Decree, is Facility specific and, therefore, as appropriate, the line item information in the Exhibits shall be adjusted accordingly, as well as any other information or assumptions provided in (or accompanying) the
Exhibits. 
 In general, the costs for the associated Water Management activities are broken out based on which activities are associated
with Phosphogypsum Stack System Closure and which activities are associated with Long Term Care. In additions to listing out the activity, and costs, any assumptions, comments descriptions or relevant information (e.g., adjusted for inflation)
needed to explain the costs shall be included. For example, specifying the estimated hours per week for an activity; yearly salary for an on-site engineer tasked with Long Term Care activities; assumptions for mowing the grassed stacks; assumptions
for the identified contingency; and what costs are captured by administrative costs.

 ADJUSTING LONG TERM CARE AND ASSOCIATED WATER MANAGEMENT COSTS TO CALCULATE CURRENT (THEN-YEAR) COSTS 

Instructions: 
  

	 	1.	Use the information and formulas, below, to determine the current (then-year) dollars for Long Term Care and associated Water Management costs (i.e., columns [C] and [E], below). 

	 	2.	The Long Term Care and associated Water Management costs in Current Dollars to be used in columns [B] and [D], below, shall be obtained, as appropriate, by calculating the inflation adjusted Long Term Care and
associated Water Management costs pursuant to Section II.A(2) of Attachment B or from the information provided in Section II.B(1)(b) of Attachment B. 

	 	3.	For purposes of determining the inflation factor, the Gross Domestic Product (GDP) Deflator is as specified in the “GDP (Chained) Price Index” of the Gross Domestic Product Deflators Used in the Historic
Tables, published by the Office of Management and Budget (“OMB”). The inflation factor used to inflate the costs in this attachment shall be derived from the mathematical average of the calculated inflation factors for each year over a
five-year period. Each year’s calculated inflation factor shall be the product of dividing the GDP for the relevant year by the GDP for the year immediately prior, beginning with the first year in which the GDP Deflator is an estimate and for
each year thereafter until the fifth year. (See Paragraph 4.d, Appendix 2, of the Consent Decree.) 

	 	4.	The inflated costs, as calculated in this Attachment B-2, shall be used to calculate the present value for Long Term Care and associated Water Management costs in Attachment B-3 and to provide information in Section
II.A(3) and Section II.B(2) of Attachment B. [Note: Each year’s adjusted costs due to inflation as specified in columns [C] and [E], below, shall be placed in the corresponding line items designated by year in columns [B] and [D] in Attachment
B-3.]

 Attachment C: Instructions 

As part of the annual update of the Phosphogypsum Stack System Closure and Long Term Care Cost Estimate, Defendant shall submit Attachment C. The costs
represented in Attachment C are in Current Dollars for the year in which the annual submittal is required. When filling out Attachment C, use the information and definition specified below, and provide any assumptions utilized to provide the
information. If it is determined that additional columns are required to accurately represent the annual volume of water to be addressed during Phosphogypsum Stack System Closure or Long Term Care, insert such information providing appropriate notes
and assumptions for the additional information. 
  

	 	1.	Ponded Water Inventory is the annual volume of water to be removed from the cooling pond, the sedimentation ponds on the Phosphogypsum Stack, the return canal and collection ditches, and from other storage or surge
ponds, or sumps in excess of  1⁄4 acre, that are part of the Phosphogypsum Stack System (such water is also known as “process water inventory”).

	 	2.	Water Balance During Closure is the average annual rainfall that is captured in the Phosphogypsum Stack System minus the average annual evaporation from the ponded water surfaces and evapotranspiration from non-ponded
surfaces. 

	 	3.	Drainable Pore Water is the annual volume of water contained within the pores of the phosphogypsum that gravity drains during and after closure of the Phosphogypsum Stack. 

	 	4.	Infiltration is the annual volume of water that infiltrates into the side slopes of the closed Phosphogypsum Stack.1 

	 	5.	Total Annual Water Volume is the summation of Ponded Water Inventory, Water Balance During Closure, Drainable Pore Water, and Infiltration water. 

	 	6.	Annual Average Removal Rate, in gallons per minute (GPM), is determined by dividing the Total Annual Water Volume by 525,600 minutes per year. 

	 	7.	Annual Water Removal Cost is the total annual cost in millions of dollars needed for the Total Annual Water Volume to achieve the applicable standards. 

	 	8.	Planning & Closure Period O&M and Monitoring Costs represent annual program management costs, miscellaneous O&M expenses, surface water monitoring costs, groundwater monitoring costs and piezometer
installation costs incurred during the five year closure construction period and one year planning period. 

	 	9.	Closure Construction Costs represent the annual cost of all materials, labor and equipment to close the phosphogypsum stack system including but not 

 

1 The area of the side slopes of the Phosphogypsum Stack is the horizontal projection of the grassed
slopes. The lined ditches and roads are not included in the slope area.

 limited to: grading and earthwork with soil and phosphogypsum; HDPE liner and associated
geosynthetics, cost of clay and mixing if utilized, liner soil cover; side slope drains; toe drains; sumps/pump stations; header pipes; grassing soil and phosphogypsum surfaces; security fence; surface water control; permitting and design services;
and construction management, QA/QC, and surveying. 

	 	10.	Program Management Costs represent the annual costs to manage the facility during the 50-year long-term care period. 

	 	11.	Long Term Care Operational Costs are based on annual: (a) costs for on-site personnel to conduct maintenance, inspection and care activities during the Long Term Care period with a 5% contingency allowance;
(b) surface water and groundwater monitoring and analysis costs; (c), mowing and land surface care costs; (d) contingency repairs (e.g., restoration of eroded areas); and (e) pump operation and maintenance costs (e.g., convey water
from seepage collection system to water treatment). 

	 	12.	Total Water Treatment and Closure Costs represent the sum of the Annual Water Treatment Costs, Planning & Closure Period O&M and Monitoring Costs, Closure Construction Costs, Long Term Care Period Program
Management Costs, and Long Term Care Operational Costs.

investment policies and guidelines.
			
		  	B.	    	Seeks to provide 25-50 basis points of excess return over benchmark, gross-of-fees, over a market cycle (~5 years).
			
		  	C.	    	Provide clear guidelines as to the allocation of investments among Treasury instruments, and investment grade corporate and municipal instruments.
		
	II. PERFORMANCE BENCHMARK	    	
			
		  	A.	    	The Trust’s performance benchmark will be the composite benchmark of its underlying strategies

  
 Mosaic 

Appendix 2, Attachment D, Form 1-B 

Table of Contents

					
		  		    	and their policy weights, which may vary through time.
			
		  	B.	    	Given the initial policy allocation, the Trust’s starting performance benchmark will be 40% US Treasuries with a maturity profile aligned with the Glide Path detailed in Section IV, 30% Barclays U.S. Corporate Intermediate
Index, and 30% Barclays U.S. Municipal 1-10 Year Index.
			
	III. POLICY ALLOCATION	  	A.	    	40% U.S. Treasuries managed by Russell, 30% Intermediate Corporates managed by Russell or a Russell-appointed sub-advisor, 30% Municipal Bonds managed by Russell or a Russell-appointed sub-advisor. These are targets subject to the
ranges set forth below. In addition, the [insert state name] Phosphogypsum Trust Fund may hold funds in interest bearing accounts of a banking institution to the extent insured by an agency of the Federal or State government.
			
		  	B.	    	The allocation to U.S. Treasuries (which may include U.S. backed obligations of U.S. Agencies) shall at all times be no less than 40% and no more than 50% of the Net Asset Value (NAV) of the [insert state name] Phosphogypsum

	IV. GLIDE PATH	  	A.	    	The US Treasury allocation will vary in its maturity profile according to changes in yield on the 10-year US Treasury as expressed by the following glidepath:
			
		  		    	 ●    10-year yield less than 2.00% = 100% 5-yr

		  		    	 ●    10-year yield 2.00-2.74% = 80% 5-yr, 20% 10-yr

		  		    	 ●    10-year yield 2.75-3.49% = 60% 5-yr, 40% 10-yr

		  		    	 ●    10-year yield greater than 4.99% = 100% 10-yr

			
		  	B.	    	Actual maturities held may vary within +/- 1 year-to-maturity from the glide path target.
			
		  	C.	    	When the 10-year Treasury yield reaches 4.99% Mosaic and Russell will reevaluate the appropriate duration target for the [insert state name] Phosphogypsum Trust Fund in light of the full funding objective and the Trust’s
asset size at which time this Glide Path may be altered to encompass US Treasury instruments with maturities greater than 10 years.
			
		  	D.	    	In conjunction with moves along the glide path, the performance benchmark will also change to include an equivalent weight in the Barclays Treasuries Bellwethers:10-Year Index and other appropriate benchmarks as the maturity of the
investments extend beyond 10 years.
		
	V. INVESTMENT PARAMETERS	    	
			
	1. Duration Range	  	a)	    	Portfolio effective duration is permitted to range from 0.70 to 1.30 times the duration of the benchmark at all times.

Corporate Guarantee for Phosphogypsum Stack System Closure and Long Term Care 

Guarantee made this [date] by The Mosaic Company, a business corporation organized under the laws of the State of Delaware, herein
referred to as “Guarantor.” This Guarantee is made on behalf of Mosaic Fertilizer, LLC (“Mosaic Fertilizer”) of 3033 Campus Dr., Plymouth, Minnesota 55441, which is our wholly-owned subsidiary, to the United States Environmental
Protection Agency (“EPA”) and [insert appropriate State designation]. 
 Whereas, pursuant to the Resource Conservation and
Recovery Act (“RCRA”), as amended, 42 U.S.C. §§ 6901 et seq., Mosaic Fertilizer has entered into a Consent Decree with EPA and [insert appropriate State designation] (dated [insert date], Docket No. [insert case
information]), to resolve the civil claims asserted by EPA, and [insert appropriate State designation] by establishing certain injunctive relief, including Financial Assurance, under the Consent Decree;1 
 Whereas, the Effective Date of the Consent Decree is defined in Section XVI (Effective
Date) of the Consent Decree; 
 Whereas, the Consent Decree requires Mosaic Fertilizer to provide Financial Assurance to EPA and [insert
appropriate State designation] to address Phosphogypsum Stack System Closure and Long Term Care, whenever required to do so, at the Operating and/or Closing Facilities; 

Whereas, in order to provide a portion of the Financial Assurance required by the Consent Decree, Mosaic Fertilizer has agreed to provide EPA
and [insert appropriate State designation] with a Guarantee, issued by the Guarantor, as set forth more fully in this Guarantee, below. 
 I.
Recitals 
 Now therefore, in consideration of the promises contained herein and for the other good and valuable consideration, the receipt and adequacy of
which is hereby acknowledged, the Guarantor agrees to the following: 
 1. Mosaic Fertilizer owns or operates the Operating and Closing Facilities
identified in the Consent Decree covered by this Guarantee: [List for each facility: EPA Identification Number, 
  

 

1 Unless otherwise defined herein, the capitalized items in this Guarantee, including the preamble and
recitals, have the meaning provided in the Consent Decree, including Appendix 1 and Appendix 2.

 name, address and Cost Estimate for each Facility]. 

2. For value received from Mosaic Fertilizer, Guarantor guarantees to EPA and [insert appropriate State designation] that, in the event Mosaic
Fertilizer fails to perform Phosphogypsum Stack Closure and/or Long Term Care at any or all of the Operating and/or Closing Facilities in accordance with the Initial Phosphogypsum Stack System Closure Plan or Permanent Phosphogypsum Stack System
Closure Plan and other terms of the Consent Decree, whenever required to do so, the Guarantor shall do so, or shall establish alternate Financial Assurance in the name of Mosaic Fertilizer in accordance within Section III.A of Appendix 2 (except for
Paragraph 10.a.(1)(c)), of the Consent Decree, in an amount at least equal to the Total [insert State name] Cost Estimate less the sum of: (i) the most recent value of the [insert State name] Phosphogypsum Trust Fund established
in accordance with Appendix 2 of the Consent Decree and as represented by the Trustee in its most recent valuation statement to Grantor and (ii) the aggregate value of any other Third-Party Mechanism secured to establish Financial Assurance in
accordance with Appendix 2 of the Consent Decree (“[insert State name] Financial Assurance Delta”). 
 3. Guarantor shall comply with the
reporting requirements of Paragraph 32.h. of Appendix 2 of the Consent Decree, including an annual Representation and Certification from the Chief Financial Officer of Guarantor stating that Guarantor has the financial resources for the next fiscal
year to fund the lesser of: (i) $415 million or (ii) the Financial Assurance Delta. 
 4. In the event that Guarantor determines, at any time for
the duration of the Guarantee, for any reason, that: (i) the Guarantor is unable to meet the terms of the Guarantee, including Recital 2; (ii) the Guarantor is unable to provide the Representation and Certification required under Recital 3
of this Guarantee; (iii) the Guarantor becomes aware of any changes in the Total Cost Estimate or the Guarantor’s financial conditions that would invalidate or otherwise be inconsistent with the Representation and Certification; or
(iv) the Guarantor becomes aware of any changes in the Total Cost Estimate that would invalidate or otherwise be inconsistent with the Representation and Certification, then Guarantor shall, within five (5) Days of such a determination,
provide notice of such determination by certified mail to Mosaic Fertilizer, EPA and [insert appropriate State designation]. Such notice shall be admissible in evidence in any litigation and create a presumption that the Guarantor cannot
provide the required Representation and Certification, and that the Guarantor cannot perform Phosphogypsum Stack System Closure and/or Long Term Care at the Operating and Closing Facilities or establish alternate Financial Assurance in accordance
with Appendix 2 in an amount that is at least equal to the Financial Assurance Delta. The Guarantor may rebut this presumption only by clear and convincing evidence. 

5. Any notice provided by Guarantor of Guarantor’s inability to comply with the requirements of this Guarantee, shall include a statement of the value of
the guaranteed obligations based on current Updated Cost Estimates, and the amount of financial resources that the Guarantor expects to have available for the next fiscal year either to perform Phosphogypsum Stack System Closure and/or Long Term
Care activities at the Operating and Closing Facilities or to provide alternate Financial Assurance.

 6. Guarantor agrees that, within thirty (30) Days after providing the notice required by Recitals 4 and 5,
or after being notified by Mosaic Fertilizer, EPA, or [insert appropriate State designation] of a determination that the Guarantor no longer is able to meet its obligations under Recital 2 of this Guarantee or is disallowed from continuing as
a Guarantor as specified in Paragraph 32.k. of Appendix 2 because the independent Certified Public Accountant has issued in the report on examination of the Guarantor’s audited financial statements an adverse opinion or a disclaimer of opinion,
or has failed to provide a Representation and Certification as required pursuant to Recital 3 or provided an invalid Representation and Certification, and if Mosaic Fertilizer during that time has not provided alternate Financial Assurance for the
[insert State name] Financial Assurance Delta (including written approval by EPA and [insert appropriate State designation]), then Guarantor shall provide alternate Financial Assurance in accordance with Section III.A of Appendix 2
(except for Paragraph 10.a(1)(c)), in the name of Mosaic Fertilizer, in an amount at least equal to the [insert State name] Financial Assurance Delta. In the event that Mosaic Fertilizer invokes dispute resolution, subject to the terms set
forth in Appendix 2, of a determination by EPA or [insert appropriate State designation], Guarantor agrees that it shall be bound by the final outcome of the dispute resolution.

under Paragraphs 32.j. and 32.l. of Appendix 2 of the Consent Decree to establish alternate Financial Assurance in accordance with Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), or to return Mosaic Fertilizer to compliance if EPA
approves a compliance plan and schedule pursuant to Section VII (Temporary Non-Compliance) of Appendix 2 of the Consent Decree. Acceptance by EPA and [insert appropriate State designation] of any compliance plan and schedule shall not relieve
The Mosaic Company of its obligations under this Corporate Guarantee. 
 8. In the event that EPA approves a compliance plan and schedule pursuant to
Section VII (Temporary Non-Compliance) of Appendix 2 to return Mosaic Fertilizer to compliance with its Financial Assurance obligations under the Consent Decree, and such plan requires the Guarantor to

Closure Plan or Permanent Phosphogypsum Stack System Closure Plan, as applicable, amendment or modification of the Consent Decree, the extension or reduction of the time of performance of Phosphogypsum Stack System Closure or Long Term Care, or any

 11. Guarantor shall remain bound under this
Guarantee for as long as Mosaic Fertilizer must comply with the applicable Financial Assurance requirements of the Consent Decree (including

appendices and attachments of the Consent Decree) for the Operating and Closing Facilities, except as provided in Recital 12 of this Guarantee. 

12. Guarantor may terminate this Guarantee by sending notice of cancellation by certified mail to Mosaic Fertilizer, EPA, and [insert appropriate State

10.a.(1)(c)), of the Consent Decree, in an amount at least equal to the [insert State name] Financial Assurance Delta. In the event that Mosaic Fertilizer fails to provide alternate Financial Assurance or obtain EPA’s and [insert
appropriate State designation] written approval of the alternate Financial Assurance, Guarantor agrees and shall provide alternate Financial Assurance in the name of Mosaic Fertilizer. This Guarantee shall not terminate unless and until EPA and
[insert appropriate State designation] has approved the alternate Financial Assurance in writing and such approved alternate Financial Assurance is in place. 

13. Guarantor expressly waives notice of acceptance of this Guarantee by EPA, [insert appropriate State designation], or by Mosaic Fertilizer.

Closure and/or Long Term Care at any or all of the Operating and/or Closing Facilities in accordance with the Initial Phosphogypsum Stack System Closure Plan or Permanent Phosphogypsum Stack System Closure Plan and other terms of the Consent Decree,
whenever required to do so, the Guarantor shall do so, or shall establish alternate Financial Assurance in the name of Mosaic Fertilizer in accordance within Section III.A of Appendix 2 (except for Paragraph 10.a.(1)(c)), of the Consent Decree, in
an amount at least equal to the Total Louisiana Cost Estimate less the sum of: (i) the most recent value of the Louisiana Phosphogypsum Trust Fund established in accordance with Appendix 2 of the Consent Decree and as represented by the Trustee
in its most recent valuation statement to Grantor and (ii) the aggregate value of any other Third-Party Mechanism secured to establish Financial Assurance in accordance with Appendix 2 of the Consent Decree (“Louisiana Financial Assurance
Delta”). 
 3. Guarantor shall comply with the reporting requirements of Paragraph 32.h. of Appendix 2 of the Consent Decree, including an annual
Representation and Certification from the Chief Financial Officer of Guarantor stating that Guarantor has the financial resources for the next fiscal year to fund the lesser of: (i) $415 million or (ii) the Financial Assurance Delta. 

4. In the event that Guarantor determines, at any time for the duration of the Guarantee, for any reason, that: (i) the Guarantor is unable to meet the
terms of the Guarantee, including Recital 2; (ii) the Guarantor is unable to provide the Representation and Certification required under Recital 3 of this Guarantee; (iii) the Guarantor becomes aware of any changes in the Total Cost
Estimate or the Guarantor’s financial conditions that would invalidate or otherwise be inconsistent with the Representation and Certification; or (iv) the Guarantor becomes aware of any changes in the Total Cost Estimate that would
invalidate or otherwise be inconsistent with the Representation and Certification, then Guarantor shall, within five (5) Days of such a determination, provide notice of such determination by certified mail to Mosaic Fertilizer, EPA and LDEQ.
Such notice shall be admissible in evidence in any litigation and create a presumption that the Guarantor cannot provide the required Representation and Certification, and that the Guarantor cannot perform Phosphogypsum Stack System Closure and/or
Long Term Care at the Operating and Closing Facilities or establish alternate Financial Assurance in accordance with Appendix 2 in an amount that is at least equal to the Financial Assurance Delta. The Guarantor may rebut this presumption only by
clear and convincing evidence.

 Mosaic Faustina 

Facility Report 
  

 II. Background 

The Faustina Facility’s primary commercial products are the solid ammoniated phosphate fertilizers: monoammonium phosphate (MAP), diammonium phosphate
(DAP), and MicroEssentials® (MES). DAP and MAP are manufactured in all three Granulation trains designated as A-Train, B-Train and C-Train. MES is produced in C-Train. Ammonia and phosphoric acid are the
primary reactants for the manufacture of MAP, DAP and MES and are consumed in the production of ammoniated fertilizers on-site. 
 Faustina does not make
phosphoric acid and its Phosphogypsum Stack System is in the process of undergoing closure pursuant to LDEQ closure requirements. A component of the Faustina Phosphogypsum Stack System, the cooling pond, consists of 38 acres and is regulated under a
LDEQ Solid Waste Permit under Louisiana law. The cooling pond is used to collect the leachate from the Phosphogypsum Stack for treatment and discharge. See Map 1. 

DAP Recycle Pond 
 The DAP Recycle Pond, which is
undergoing closure, is regulated under a LDEQ permit as a solid waste impoundment under Louisiana law. The DAP Recycle Pond collects rainwater. The DAP Recycle Pond is usually separated from the cooling pond, but Mosaic occasionally transfers water
from the DAP Recycle Pond to the cooling pond in order to maintain capacity in the DAP Recycle Pond (e.g., after heavy rain events). 

III. First Saleable Products at Faustina 

Faustina does not generate First Saleable Products as defined in the CD. Rather, it imports the following First Saleable Products from Mosaic’s Uncle
Sam Facility and other phosphoric acid producers and uses them as direct feedstocks to DAP, MAP and MES production: 

	 	1)	30% phosphoric acid 

	 	2)	54% clarified phosphoric acid (greater than 1% solids) 

	 	3)	High solids acid (HSA) - phosphoric acid 

 IV. Phosphoric
Acid Storage and Consumption1  
  

	 	A.	Phosphoric Acid Storage 

There are four phosphoric acid storage tanks (Phos Acid Storage Tanks) that store imported phosphoric acid with concentrations ranging from 30 to 54%. These
tanks are referred to as the East, West, North and South Tanks and are all located in an area of the plant referred to as the Phosphoric Acid Tank Farm (See Figures 4, 5 and 6). These four tanks are also periodically used to store cleaning wastes
that are used in Granulation.1 At the time of the drafting of this Facility Report, the four tanks in the Phosphoric Acid Tank Farm are not equipped with secondary containment. 

 
  

1 This Section describes current operations, which will be altered as described in Section VI (Compliance
Projects) once the GPHTs are installed pursuant to the schedule set forth in Appendix 6 (RCRA Project Narrative and Compliance Schedule) to the CD.

Table of Contents

 Mosaic Faustina 

Facility Report 
  

 However, secondary containment will be installed (see Figure 7) pursuant to the schedule set forth in
Appendix 6 (RCRA Project Narrative and Compliance Schedule) to the CD. The East Tank and West Tank share a pump and piping system serviced by an acid brick lined sump. Any leaks or discharges (other than cleaning wastes) from the East or West Tanks
to this shared sump are recovered and pumped back to the East, West, North, or South Tanks. The North Tank and South Tank share a pump and piping system serviced by a stainless steel sump. Any leaks or discharges (other than cleaning wastes) from
the North or South Tanks to this shared sump are recovered and pumped back to the North, South, East, or West Tanks. 
 The Phos Acid Storage Tank Farm
area slopes toward a section of the earthen ditch and will be addressed by Section VI. Project 1 Secondary Containment in Phosphoric Acid Tank Farm. The section of the earthen ditch leading to the DAP Recycle Pond has been completely filled in with
earth thereby isolating the Phosphoric Acid Tank Farm from the DAP Recycle Pond. 
 The Phos Acid Storage Tanks are cleaned periodically with fresh water
and the wastewaters and solids are then transferred via a concrete pad and a sump to another Phos Acid Storage Tank. From the Storage Tank, the solution is transferred to and used in Granulation. 

 

	 	B.	Phosphoric Acid Transfer to Granulation 

 

	1)	Acid Transfer between Barge Unloading and the Phosphoric Acid Storage Tanks 

 Faustina has one
(1) primary transfer line from the barge unloading area to the Phos Acid Storage Tanks in the Phosphoric Acid Tank Farm area. This line transfers either 30%, 54% or HSA phosphoric acid from the barges to a Phos Acid Storage Tank. This line is
cleaned with SACS generated at and barged from Uncle Sam solely for this purpose to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. 

The location of the transfer line is shown in Figure 3. The estimated line length and cleaning frequency is listed in Table 2. 

 

	2)	Acid Transfer between the Phosphoric Acid Storage Tanks and the Granulation Plants 

 Faustina has four
(4) primary transfer lines that transfer acid from the Phos Acid Storage Tanks to the Granulation plants’ reactors and scrubber seal tanks. These lines are designated as the A-line, B-line, C-line and Spare line. These lines are cleaned
with Faustina Cleaning Solution to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. Periodically, these lines are used to transport waste from the Phos Acid Storage Tanks to Granulation for use1. The
locations of the transfer lines are shown in Figure 4. The estimated line lengths and cleaning frequencies are listed in Table 3. 
  

	3)	Acid Transfer between the Truck Unloading and the Phosphoric Acid Storage Tanks 

 Faustina has one
(1) transfer line that transfers acid from the truck unloading area to the Phosphoric Acid Tank Farm. These lines are cleaned with Faustina Cleaning Solution to remove precipitated solids and scale to maintain acceptable pressure levels and
acid flow rates. 
 The location of the transfer line is illustrated in Figure 5. The estimated line length and cleaning frequency is listed in Table 4.

 Mosaic Faustina 

Facility Report 
  

	 	C.	Granulation  

Faustina has three Granulation plants (A-Train, B-Train, and C-Train, referred to collectively as Faustina Granulation plants) that produce MAP, DAP and
MES. Faustina’s Granulation plants use 30% phosphoric acid as the scrubbing media in the first stage of the air pollution control devices (“APCDs”). 

The APCDs in A-Train, B-Train and C-Train consist of a first stage system that uses phosphoric acid for scrubbing and a second stage scrubber system that
uses non-hazardous DAP Recycle Pond water or clarified water or GPU Effluent for scrubbing. The scrubbing media is recirculated through the scrubbers and a slip stream is sent to the reactor. All the effluents from these scrubbers are used in
Granulation. 
 Faustina Granulation plants use clarified water, hot condensate, Granulation Plant Holding Tank Effluent (described in Section VI
(Compliance Projects), Project 3), or non-hazardous DAP Recycle Pond water. These solutions are referred to collectively as “Faustina Cleaning Solution” when used for cleaning. 

Faustina uses a sump referred to as the Granulation Sump, discussed further in the Section below, as a central collection point for: wash-down of the floor
area within the curbing and sloped area of the Granulation plants, stormwater, and Faustina Cleaning Solution transferred via concrete ditches from each of the three Granulation plants during cleaning and maintenance. The Granulation Sump is a GPU
that transfers its contents to another GPU, the Existing Holding Tank, which then transfers the content for use in Granulation. The Granulation plant has also recently connected spare tanks, the North Holding Tank and the “Storm Water
Tank” to receive excess solution from the Granulation Sump, which can then be transferred to the Existing Holding Tank for use in Granulation (Diagram 1). The Existing Holding Tank is the source of scrubber liquor (normal operation) to all
three plants. 
 The concrete area underlying the Faustina Granulation plants are designated as the “granulation pad.” The granulation pad
slopes and drains to concrete drainage ditches, which are below grade and are lined with an acid-resistant coating that will be inspected and repaired in accordance with Project 7, Section VI (Compliance Projects). All of these drainage ditches are
depicted in Diagram 2 and flow into the Granulation Sump located near Train A (“Granulation Sump Ditches”). 
 The concrete floors within the
Faustina Granulation plants are washed with non-hazardous clarified water. Wastes generated from the use of Faustina Cleaning Solution are input into Granulation via the GPUs. See Figure 1 and Figure 2. 

Granulation Sump 
 The Granulation Sump (See Diagram
2) is constructed of concrete and is lined with acid-resistant brick. The Granulation Sump is being modified to meet the design specifications of a Hazardous Waste Tank System as detailed in Section VI. Project 5. 

The inputs to/contents of the Granulation Sump are comprised primarily of clarified water, process equipment wash water, Granulation fines, and stormwater
flowing into the granulation pad drainage ditches. The contents of the Granulation Sump are returned to Granulation via the GPU referred to as the Existing Holding Tank. The contents of the Existing Holding Tank are used in Granulation. If

Table of Contents

 Mosaic Faustina 

Facility Report 
  

 
the volume of the Existing Holding Tank becomes too low it can receive additional makeup material from the “Storm Water Tank,” from the DAP Pond, or from the clarified water system. The
Granulation Sump has a water level “float” that triggers a pump to transfer the contents of the Granulation Sump to the Existing Holding Tank, the North Holding Tank, or the “Storm Water Tank” for use in Granulation. 

When the Granulation Sump is cleaned to remove solids, fresh water sprayed with a fire hose is used to agitate the contents of the Granulation Sump. The
Granulation Sump wastewaters and solids are sent to the Existing Holding Tank, the North Holding Tank, or the “Storm Water Tank” for use in Granulation. 

Wastewaters and solids from equipment washouts in the Granulation plant are drained to the granulation pad where they enter the drainage ditches that
gravity flow to the Granulation Sump. The contents from the Granulation Sump are sent to the GPHTs for use in Granulation. Sulfuric acid is occasionally used in “boil-outs” to remove scale from process equipment. Ammonia is added to the
boil-out solution to adjust the pH within the tank and then the solution flows over the granulation pad to the Granulation Sump where it is returned to Granulation via the GPHTs. 

Following commencement of operations of the GPHTs, wastes from the Existing Holding Tank and the Granulation Sump units may be input to a GPHT for use in
Granulation in accordance with Section VI. Compliance Projects of the Facility Report. 
 Sump 101 

The 101 Sump (see Diagram 2) collects stormwater and non-hazardous product spills from the shipping area and transfers it to the Granulation Sump for use in
Granulation. The contents of Sump 101 are pumped over a short distance over the road, running east-west, to the Granulation Sump. Sump 101 is on the North side of the road, as is the granulation warehouse. The high point crest of this road divides
the North side from the “phos acid” or “wet” side (reactor/scrubbers/ phosphoric acid storage tanks) on the South side. Stormwater from the North side of the road flows to Sump 101, while stormwater from the South side of the
road flows into the Granulation Sump. Sump 101 is a below grade stainless steel-lined concrete sump. Sump 101 only receives non-hazardous stormwater and non-hazardous floor wash wastewaters from around the granulation warehouse. 

Existing Holding Tank Sump 
 The Existing Holding Tank
Sump (see Diagram 2) is constructed of concrete with a stainless steel liner and collects stormwater and pavement wash wastewaters, as well as spills and leaks within the secondary containment for the Existing Holding Tank. The Existing Holding
Tanks Sump’s contents are transferred to the Existing Holding Tank for use in Granulation. The Existing Holding Tank Sump will be modified to meet the design specifications of a Hazardous Waste Tank System as detailed in Appendix 6 (RCRA
Project Narrative and Compliance Schedule) of the CD and Section VI. Project 8 of this Facility Report.

 Project 3: Granulation Plant Holding Tank Installation

 Mosaic will install two new tanks and/or convert at least one existing tank. These tanks will be referred to as Granulation Plant Holding
Tanks (GPHTs) and will be identified as GPUs. The GPHTs will be used to capture cleaning wastes generated from the use of Faustina Cleaning Solutions. Spills and leaks within the Granulation plants will be placed into the GPHTs for use in
Granulation. At times, stormwater run-off may be transferred to the GPHTs for use in Granulation. The GPHTs also will receive the cleaning wastes from the Phos Acid Storage Tanks and the Barge Transfer Line. Mosaic plans to install these GPHTs in
the approximate locations depicted in Figure 7, but the ultimate location of these GPHTs may differ. 
 Contents of the GPHTs (GPU Effluent) will be fed
to the EHT, the acid scrubber system or the reactor within the Granulation plant for use in Granulation. Mosaic plans to use one of the two GPHTs to handle stormwater when the tank is not in service as a back-up tank to one of the other GPUs; this
will allow the stormwater to be transferred to the LPDES permitted water treatment plant or LDEQ permitted effluent pond system for handling. 
 Project 4: Interim Granulation Plant Units Tank and Transfer Line Operating Requirements 

Mosaic operates Interim Granulation Plant Units (IGPUs) that manage, store or transport wastes from Downstream Operations (hereinafter called
“Downstream Waste” or “Downstream Wastes”) for use in Granulation. Mosaic intends to use these units to manage, store or transport Downstream Wastes until such time as the Granulation Plant Holding Tanks are put in service to
replace the IGPUs. 
 The requirements of this Project apply when the IGPUs identified in Project 4 of the Faustina Compliance Schedule set forth in
Appendix 6 (RCRA Project Narrative and Compliance Schedule) to the CD is in Downstream Waste handling service. 
 Mosaic’s compliance obligations
with respect to the IGPUs is set forth in Paragraph 16(b)(2)(iii) of the CD. 
 Project 5: Interim
Granulation Plant Units – Sump Operating Requirements 
 Mosaic operates Interim Granulation Plant Units (IGPUs) that manage, store or
transport Downstream wastes for use in Granulation. Mosaic intends to use these units to manage, store or transport Downstream wastes until such time as the Granulation Plant Holding Tanks are put in service to replace the IGPUs. 

The East/West and North/South Phos Acid Storage Tank Sumps, which are IGPUs, will be in periodic Downstream Waste handling service. The requirements of this
Project apply when the East/West and/or the North/South Phos Acid Storage Tank Sumps are in Downstream waste handling service.

VII. Containment of Phosphoric Acid Spills and Leaks 

Containable Impervious Areas 
 Containable impervious2 areas listed below are found in Figure 6. 

	 	1)	Phosphoric Acid Tank Farm Area Sumps 

	 	 	The Phosphoric Acid Tank Farm is designed to recover spills and leaks via two sumps (as described in Section IV. A). The areas between the sumps and the tanks are concreted in order to collect spills and leaks. Any
material captured in the sumps is pumped back into one of the Phosphoric Acid Storage Tanks in the Phosphoric Acid Tank Farm. The configuration of the existing system is shown in Diagram 2. Project 1 will install additional secondary containment in
this area. See Figure 7. 

	 	2)	A-Train Granulation plant 

	 	3)	B-Train Granulation plant 

	 	4)	C-Train Granulation plant 

	 	5)	All GPUs (See Figure 7) 

  

 
 2 Note, the use of the term “impervious” in this Section does not refer to a particular definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to
penetration, such as concrete, liners, steel, epoxy, etc. The term impervious in this Section does not include gravel or soil.

 As required by Paragraph 16 of the CD, spills and leaks of phosphoric acid and sulfuric acid onto
containable impervious areas, designated by Figure 6, shall be recovered and transferred for use in Granulation, either directly or via the GPUs, or managed in accordance with applicable law. 

Outside Impervious Areas 
 Spills and leaks of
phosphoric acid and sulfuric acid, outside an impervious area, shall be managed and reported in accordance with all applicable law. 

VIII. Process Wastewater Inventory Management Plan 

Faustina uses lime to treat acidic wastewater leached from the Phosphogypsum Stack collected in the cooling pond prior to discharging it through the NPDES
Outfall 001. Lime treatment is part of the Process Wastewater System management and closure plan (see Permit Nos. LA0029769, AI 2425/GD-093-0791/P-0063/CPL20050001). Lime treatment is a neutralization process that results in the formation of a fine
whitish-gray sludge primarily consisting of calcium fluoride, calcium phosphate and unreacted lime solids. 
 Following the installation of the two new
GPHTs, Mosaic plans to operate with one of the GPHTs being used for stormwater when the tank is not in service as a back-up tank to the other GPU; this will allow the stormwater to be used in Granulation or transferred to the LPDES permitted water
treatment plant or LDEQ permitted effluent pond system. The foregoing shall not relieve Mosaic of its obligations under any applicable law.

 II. Background3 
 Mosaic’s Uncle Sam Facility primarily produces unclarified 54%4 phosphoric acid (P2O55) referred
to as 54% Run of Plant (ROP), clarified 54% phosphoric acid referred to as 54% clarified ROP, High Solids Acid (HSA) and Fluorosilicic Acid (FSA). The 54% ROP, 54% clarified ROP, HSA, a clarified intermediate grade of acid (30% P2O5), and blends thereof are transported via barge across the Mississippi River to Mosaic’s Faustina facility where they are used to
produce the granulated ammoniated phosphate fertilizers: monoammonium phosphate (MAP), diammonium phosphate (DAP) and MicroEssentials (MES). 
 Mosaic
Uncle Sam produces phosphoric acid by the digestion of phosphate rock imported from Florida and other places with sulfuric acid. Mosaic Uncle Sam manufactures phosphoric acid in a single Phosphoric Acid Plant (PAP) with two distinct reactors. The
reaction yields 30% P2O5 and Phosphogypsum (gypsum). Gypsum is filtered from the phosphoric acid on rotating pan filters, slurried with
process wastewater in Gypsum Slurry Tanks, and then the resultant slurry is pumped to a Phosphogypsum Stack (gypstack). Because the production of phosphoric acid is a water-intensive process and water is used throughout the process (e.g., in the
ball mills, and as a pipe and tank cleaning agent), approximately 1.5 billion gallons of Process Wastewater is constantly stored in and circulating throughout the facility’s Phosphogypsum Stack System. 

Mosaic Uncle Sam deposits slurried gypsum in a Phosphogypsum Stack located east of the facility. 

Mosaic Uncle Sam’s Phosphogypsum Stack System includes a pond system that consists of four cooling ponds located directly east of the production
complex and the ponds’ connecting ditches. Mosaic operates the Phosphogypsum Stack System under a Gypsum Management Area Solid Waste Permit issued by the Louisiana Department of Environmental Quality (LDEQ). 

III. First Saleable Products 

The line marking the division between Upstream and Downstream Operations lies at the point of generation of the First Saleable Product. Mosaic Uncle Sam has
the capability to generate four first Saleable Products that are transported via barge to Mosaic’s Faustina facility to be used as direct feed stocks to MAP, DAP and MicroEssentials® production: 

	 	●	 	30% clarified acid; 

	 	●	 	54% unclarified ROP (greater than 1% solids); 

	 	●	 	54% clarified ROP; 

	 	●	 	HSA (High solids acid); 

  

 

3 This Background Section is provided solely for informative purposes and is not a definitive or
exhaustive description of the Facility or its operations. 
 4 All phosphoric acid concentrations are
approximate and fluctuate slightly 
 5 Note that although the terms P2O5 and phosphoric acid
(H3PO4) are used interchangeably, the concentrations are not interchangeable. Mosaic manufactures phosphoric acid, however, in this
document we refer to the concentration of the acid in terms of P2O5 concentration, rather than phosphoric acid concentration. P2O5 concentration can converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to
an approximate concentration of P2O5 by multiplying by 0.7242.

 Downstream Operations at Mosaic Uncle Sam are associated with the storage and transport or use of these
saleable commodities. In conjunction with the production of 30% acid and the production of 50% clarified acid, Mosaic Uncle Sam recovers fluoride vapors to produce FSA as a First Saleable
Product.6 
 IV. Phosphoric Acid and FSA
Production – Phosphoric Acid Plant 
 Figure 6 identifies Upstream Operations, Downstream Operations, Mixed-Use Units and Grandfathered
Units for the Phosphoric Acid Plant. This figure does not identify all BHT Recovery Units-Downstream. 
 
A. Standard Acid Flow Configuration 
 The Phosphoric Acid Plant produces three concentrations of phosphoric acid for use in fertilizer
manufacturing: 30% P2O5, 40%
P2O5 and 54% P2O57,8. The 30% acid that is not used directly as feedstock to fertilizer manufacturing is further processed into 54% P2O5 in Upstream Operations. The typical phosphoric acid manufacturing process described below is illustrated in process block flow Diagram (Figure 3). Deviations from the standard acid flow
configuration are necessary on periodic short-term intervals. 
 Mosaic Uncle Sam produces phosphoric acid in two reactors within the Phosphoric Acid
Plant designated as Phosphoric Acid Reactor North A&F (Attack & Filter) (TNK027) and Phosphoric Acid Reactor South A&F (TNK028). The acid from both reactors mixes at the North 30% Clarifier Feed Storage Tank (“North 30%
Tank” - TNK149) and the South 30% Clarifier Feed Storage Tank (“South 30% Tank” - TNK150). Prior to mixing at the North 30% Tank (TNK149) and South 30% Tank (TNK150), the acid flows as follows: 

Phosphoric Acid Reactor North A&F (Upstream): 

Post-reactor, unclarified 30% acid is gravity fed to the North Filtrate Tank (TNK036) via the North Filter and then pumped to either the
North 30% Tank (TNK149) or the South 30% Tank (TNK150). 
 Phosphoric Acid Reactor South A&F (Upstream): 

Post-reactor, unclarified 30% acid is gravity fed to the South Filtrate Tank (TNK050) via the South Filter and then pumped to either to the
North 30% Tank (TNK149) or the South 30% Tank (TNK150). 
  
  

6 As of the date of this Facility Report, Uncle Sam only produces FSA for use as a cleaning solution. 

7 Note that although the terms P2O5 and phosphoric acid (H3PO4) are used interchangeably, the concentrations are not
interchangeable. Mosaic manufactures phosphoric acid, however, in this document we refer to the concentration of the acid in terms of
P2O5 concentration, rather than phosphoric acid concentration. P2O5 concentration can be converted to an approximate concentration of phosphoric acid by multiplying by 1.3808. Phosphoric acid is converted to an approximate concentration of P2O5 by multiplying by 0.7242. 
 8 All phosphoric acid concentrations are approximate and fluctuate slightly.

on a temporary or permanent basis, with the exception of the following: 

	 	●	 	Phosphoric Acid Reactor North A&F; 

	 	●	 	Phosphoric Acid Reactor South A&F; 

	 	●	 	Filters; 

	 	●	 	Gypsum Slurry Tanks. 

 C. Acid Transfers to Downstream
Operations 
  

	1)	Acid Transfer from the Phosphoric Acid Plant to Barge Loading (BHT Recovery Units) 

  

	  	Mosaic Uncle Sam - has one primary transfer line that serves to transport 30% phosphoric acid, 54% phosphoric acid, and High Solids Acid to the barges for transfer into one of four phosphoric acid holding tanks at
Mosaic’s Faustina facility for use in the production of DAP/MAP. The transfer line is cleaned with a cleaning solution to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. This line may be cleaned
and the acid-containing waste recovered via the Big Holding Tank. The location of the transfer line is illustrated in Figure 5. The line length and cleaning frequency is listed in Table 4. 

D. Fluorosilicic Acid (FSA) Standard Process Configuration 

Mosaic Uncle Sam captures fluoride vapors from 2nd Stage (#4, #5) and Final Stage (#6) Evaporators to
produce FSA for use as a cleaning solution. A generic depiction of the FSA production process is illustrated in Diagram 1. 
 The second (#4, #5) and
final Stage (#6) Evaporators each have a FSA production unit, also called a “Swift Tower,” integrated with a barometric condenser. The Swift Tower receives gas emitted from the concentration of 40% P2O5 to 54% P2O5 through
evaporation. The gas is condensed in the Swift Tower and the liquid is continuously recirculated through a seal tank and back through the Swift Tower to maintain the seal and operation of the FSA Swift Tower. 

FSA is not always produced. When FSA is not being produced for use as a cleaning solution, the gases pass through the Swift Tower to the barometric
condenser, there is no recirculation of FSA through the Swift Tower, and therefore FSA is not produced. Even when FSA is not being produced, the FSA Seal Tank remains an essential part of the Phosphoric Acid Evaporator circuit by sealing the Swift
Tower downleg.

Table of Contents

 Mosaic Uncle Sam 

Facility Report 
  

 When FSA is being produced for use as a cleaning solution, recirculated liquid will continue to absorb
fluoride vapors until the desired quality of FSA is obtained. 
 Once the FSA reaches the desired quality for use as a cleaning solution, a slip stream
from the recirculation line between the FSA Seal Tank and FSA Swift Tower is sent to the A Reactor Storage Tank (TNK106) where it can then be used as a cleaning solution. 

Prior to commencement of operations of the BHT, FSA produced for use as a cleaning solution may continue to be managed consistent with Mosaic’s
consolidated waste management practices submittal dated September 8, 2015. Following commencement of operations of the BHT, FSA produced for use as a cleaning solution may be used and then must be sent to the Big Holding Tank, as described in
Section VI (Compliance Projects) of this Report, for recovery of acid values.

 Transfer of FSA 
  

	 	1)	FSA Transfer from the South Seal Tank to FSA Storage A Reactor (TNK 106) for use as a cleaning solution. 

Mosaic has two transfer lines that serve to transport FSA from FSA South Seal Tank (TNK 066) to FSA Storage A Reactor (TNK 106). The transfer
lines are cleaned with a cleaning solution as needed to remove precipitated solids and scale to maintain acceptable pressure levels and acid flow rates. This line may be cleaned and the acid-containing waste recovered via the Big Holding Tank.

 Mosaic Uncle Sam has no Granulation Plants on site. Granulation is performed at Mosaic’s Faustina facility. 

VI. Compliance Projects 

The projects described below are not all the projects in Appendix 6 (Compliance Schedule) to the Consent Decree but are the projects that are recovery
related – the BHT. Timeframes for completion of the projects are found in Appendix 6 (Compliance Schedule) to the Consent Decree. 
 Projects 1 and 2
comprise a plan that will enable Mosaic Uncle Sam to clean Upstream, Mixed-Use, Grandfathered, and BHT Recovery Units and recover acid values from the wastes as described below.10 

A. BHT and Cleaning Solution Return Piping 

1. Project Descriptions 

Project 1: Big Holding Tank and Wash Solution System in the Phosphoric Acid Plant 

The Big Holding Tank and wash solution system (together designated the “BHT system”) project in the Phosphoric Acid Plant shall install new or
convert an existing tank(s), piping, and controls to enable Mosaic to recover the value of wastes as specified in Section VI.A.2. Project Operations, below. 

Mosaic Uncle Sam plans to convert Storage Tank D (TNK126) to be the primary BHT. Storage Tank E (TNK124) will be the designated back-up tank (which when
used in other services shall not alter or nullify the status of the backup tank as a BHT Recovery Unit or preclude its use as a part of Upstream Operations, if appropriate). The backup tank will be used during cleaning or maintenance of the BHT
tank. Cleaning waste from the BHT backup tank(s) will be handled in the same way as the cleaning waste from the BHT itself as described in Section 2. Phosphoric Acid Plant Cleaning Procedures of the BMP. 

 
  

10 The project numbers coincide with the project numbers in Appendix 6 (Compliance Schedule), and
therefore are not sequential.

 In addition, new or upgraded pumps, motors, small pump tanks, and instrumentation may be needed to ensure
the return to the BHT cleaning wastes and spills and leaks of: (1) phosphoric acid, sulfuric acid, FSA, SACS, PACS, FSACS, or BHT Effluent; or (2) NHACS, Process Wastewater, or Phosphogypsum Stack System Wastewater when mixed with any of
the preceding solutions due to spills, leaks, or cleaning of leaks and spills. Project 1 necessarily coincides with Project 2 below. 
 Project 2:
Cleaning Solution Return Piping 
 Mosaic will install new piping to enable Mosaic to (1) clean phosphoric acid transfer lines from the Phosphoric
Acid Plant to the Barge Loading and return those cleaning wastes to the BHT; (2) clean BHT Recovery Units located at the Phosphoric Acid Plant and the Barge Loading and return those wastes to the BHT; and (3) clean FSA system and return
wastes to the BHT. 
 2. Project Operations 

The wash solution system will be comprised of the BHT and the Boilout (SACS/FSACS) tank(s), along with pumps and piping to supply cleaning solution to units
that are part of Upstream Operations or, are identified as Mixed-Use, Grandfathered, or BHT Recovery Units. 
 Phosphogypsum Stack System Wastewater,
Process Wastewater, fresh water, condensate or other water sources may be mixed with sulfuric acid, FSA or BHT Effluent in the Boilout tank(s) or BHT. The equipment and lines that are part of Upstream Operations or are identified as Mixed-Use,
Grandfathered, or BHT Recovery Units may be washed with SACS or FSACS either from the BHT or the Boilout tank and the solutions may be returned to the BHT. 

In addition, the BHT will enable Mosaic to recover the value of wastes generated from the use of SACS, FSA, FSACS, PACS, NHACS, Process Wastewater,
Phosphogypsum Stack System Wastewater, BHT Effluent from pipes, tanks, process equipment, or other storage or transport units that: (i) are part of Upstream Operations, (ii) serve to manage, store, or transport Bevill-Exempt Wastes; or
(iii) are identified as Mixed-Use, Grandfathered Units, or BHT Recovery Units in this Facility Report. In accordance with the BMP, the BHT will also enable Mosaic to recover spills and leaks in Containable Impervious Areas described in Section
VII of this report. 
 The BHT shall in turn return the recoverable streams into Upstream Operations where their values are recovered or managed through
the following (Figure 1): 

	 	1.	as an intermediate wash on the filter, prior to the final cake wash, to inhibit scale formation. This wash ultimately circulates back to the reactor (attack tank); and/or 

	 	2.	as direct make up to the phosphoric acid reactors; and/or 

	 	3.	added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactors; and/or 

	 	4.	Discharged to the Phosphogypsum Stack System, if in compliance with the LDR standards set forth in 40 C.F.R. Part 268, Subpart D; and/or 

	 	5.	if the P2O5 content is at least 8%, the BHT Effluent may be placed in the evaporator feed tanks for P2O5 recovery.

 B. Scrubber System Upgrades 
 Project 4: Scrubber System Upgrades 

Mosaic will install a single large scrubber to replace five existing ejector venturi scrubbers (A Scrubber (004), B Scrubber (005), #1 Scrubber, #2 Scrubber,
and G Tank Scrubber) located in the phosphoric acid and FSA storage areas. These scrubbers serve Upstream, Mixed Use and Downstream tanks. The new scrubber will be named the Tank Farm Scrubber and will reduce usage of the Process Wastewater by
approximately 200-600 gallons per minute. 
 VII. Containment of Phosphoric Acid, Sulfuric Acid and FSA
Product Spills and Leaks within the Phosphoric Acid Plant 
 Any impervious12
manufacturing or storage areas not identified in this section as Containable Impervious Areas are considered to be Non-Segregable Areas. 
 Non-Segreable Areas 
 Approximately 20% of Mosaic Uncle Sam’s Phosphoric Acid Plant
has a concrete pad installed within the process areas (Figure 7: Phosphoric Acid department concreted areas and water trenches). In several areas, the concrete pad is sloped towards trenches that transport any leaks and spills to the 04 Basin active
water reservoir. Due to the engineered slope of the concrete pad in these areas and the configuration of the Phosphoric Acid Plant, spills and leaks of phosphoric acid, sulfuric acid, and FSA onto the concrete pad cannot be feasibly segregated
(“Non- 
  
  

12 Note, the use of the term “impervious” in this section does not refer to a particular
definition of impervious or a particular leakage rate, but instead is used to mean a surface barrier to penetration, such as concrete, liners, steel, epoxy, etc. The term impervious does not include gravel or soil.

Spills and leaks of phosphoric acid, sulfuric acid, and FSA onto impervious areas designated by Figure 6: Equipment designations for Upstream, Mixed Use,
Grandfathered and BHT Recovery Units with Containable Impervious Area delineations. Containable Impervious Areas shall be separately contained and then recovered, or managed in accordance with the BMP. The foregoing shall not relieve Mosaic of its
obligations under any applicable law. 
 Other Areas 

Any leak or spill of a hazardous material, including phosphoric acid, FSA and sulfuric acid, that is not contained within Containable Impervious Areas or
Non-Segregable Areas of the plant shall be managed and reported in accordance with the BMP. The foregoing shall not relieve Mosaic of its obligations under any applicable law. 

VIII. Proposed Phosphoric Acid Production Operations 

Mosaic has advised EPA and LDEQ that it is considering one or more of the following projects at its Uncle Sam facility, but planning has not evolved to where
detailed information is available. 
 Figure 6 depicts equipment designations for Upstream, Mixed Use, Grandfathered and BHT Recovery Units. In the event
that Mosaic reconfigures its Facility in accordance with Figure 8, Figure 9, Diagram 2, Diagram 3 and Diagram 4, then Figure 8 and Figure 9 shall replace Figure 6 identifying Upstream Operations, Grandfathered Units, BHT Recovery Units, and Mixed
Use Units for the Phosphoric Acid plant. 
 However, the Consent Decree does not bind Mosaic to implement the proposed project(s) as depicted in Figure 8,
Figure 9, Diagram 2, Diagram 3, and Diagram 4. If Mosaic chooses to implement any changes through a different process than depicted in Figure 8, Figure 9, Diagram 2, Diagram 3 and Diagram 4, this Facility Report shall then be modified prior to
implementation pursuant to Section XVIII (Modifications) of the Consent Decree and EPA and LDEQ will determine, consistent with this Facility Report, whether the new process as designed involves Upstream Operations, Mixed-Use Units, Grandfathered
Units, BHT Recovery Units, or Downstream Operations and coordinate with Mosaic to amend the Facility Report to memorialize those determinations. Such determination shall be conditioned upon the new

 process being built substantially as designed. If the new process deviates from that standard, EPA and LDEQ
will determine whether the new process as built involves Upstream Operations, Mixed-Use Units, Grandfathered Units, BHT Recovery Units or Downstream Operations and amend the Facility Report to memorialize those determinations consistent with the
descriptions below.

 INTRODUCTION 

Mosaic has developed Appendix 5: Best Management Practices Plan (hereinafter either “BMP” or “Plan”) to reduce
unintended (and seek to eliminate unauthorized) inputs of phosphoric acid, sulfuric acid, fluorosilicic acid (FSA), SACS, PACS, and FSACS to Process Wastewater entering the Phosphogypsum Stack System. Where possible, Mosaic will capture and reuse
these acid loses. 
 Through the BMP, Mosaic has established procedures to address the management, tracking, and reporting of phosphoric
acid, sulfuric acid, and FSA leaks and spills for four of its fertilizer production facilities—Bartow, New Wales, Riverview, and Uncle Sam1—in areas of the phosphoric acid plants (post
first-stage filtration, e.g. bird or belt filters), including acid clarification and evaporation, and in the granulation plants. The specific details of the BMP for the phosphoric acid and granulation plants are discussed in the Sections that follow
and the referenced Attachments. Where noted, certain BMP procedures are dependent upon the commencement of operation of the compliance projects set forth in Appendix 6 (Project Narrative & Compliance Schedules), to the Consent Decree. 

SECTION 1:  PHOSPHORIC ACID PLANTS LEAK/SPILL DETECTION 

SYSTEMS AND RESPONSE PROCEDURES 

1.1        General 

Mosaic will implement two approaches to increase the likelihood of detecting non-segregable acid leaks, spills and process upsets: operator
inspections and process stream conductivity monitoring, which are discussed in greater detail below. While conductivity monitoring is exclusive to the Process Wastewater system (non-segregable areas), operator inspections also serve to identify
observable leaks and spills of acids regardless of the area of the plant where they occur – non-segregable, contained impervious, or outside contained impervious area. 

1.2        Release Reporting 

Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill of any
hazardous material listed in Attachment A, Table 1 BMP Actionable Volumes (hereinafter, “Table 1 Materials”) pursuant to this BMP. This BMP does not 

 
 1 Mosaic’s Faustina facility is not covered under this Appendix and Mosaic’s Plant City facility is the subject of a separate BMP Plan developed under a separate consent decree.

Table of Contents

 
relieve Mosaic of its obligation to provide any such notifications under applicable federal, state, or local laws. 

1.3        Inspections 

Operators shall visually inspect the plant for leaks and/or spills of phosphoric acid, sulfuric acid, and FSA during their normal rounds a
minimum of twice per shift and document the inspections. The operator shall correct any leaks from valves, flanges, pumps, or any other equipment that can be readily and safely corrected at the time of discovery. The incident shall be recorded in
the tracking database known as AON Risk Management software or any other future data collection system which replaces or supplements AON Risk Management software (hereinafter, collectively referred to as “AON”). Any leaks or spills in
excess of the applicable volume listed in Attachment A, Table 1 BMP Actionable Volumes (hereinafter “BMP Actionable Volume (Table 1)”) shall be reported to management for further action and recorded in AON. Reporting responsibilities are
outlined in Mosaic’s Spill Reporting Policy and Procedure. 

1.4        Conductivity System Description: Non-Segregable
Spills/Leaks2 
 New Wales, Bartow, Riverview, and Uncle Sam shall
monitor key outgoing streams (see Attachment B) with a conductivity system to enable the continuous detection of changes in conductivity that indicate occurrence of detectable acid leaks and spills. Each key outgoing stream shall have a conductivity
probe to continuously measure the conductivity of the Process Wastewater as shown in Attachment B of this Plan. The conductivity of the return Process Wastewater stream shall be displayed on the operators’ distributive control system, see
Attachment B of this Plan. 
 If acid leaks or spills into an outgoing water or Process Wastewater stream, the conductivity of the water
or Process Wastewater increases because the acid has a higher conductivity than the water. Visual alarms (see example in Attachment B of this Plan) shall be triggered if the conductivity increases beyond the set alarm limits for a 5-minute interval.
Upon triggering of such an alarm, the area around the probe will be investigated. Individual conductivity probe locations are found in Attachment B of this Plan. 

Individual conductivity probes will alarm based on the preliminary trigger values set for each probe found in Attachment B of this Plan. The
targets shown in Attachment B of this Plan are the initial temperature compensated conductivity targets for Bartow, New Wales, Riverview and Uncle Sam, respectively. Pursuant to Section 9: BMP Performance Standards, of this BMP, Mosaic will
monitor the conductivity probes at Bartow, New Wales, and Riverview for a year after June 30, 2015 and will monitor the conductivity probes at Uncle Sam for a year after January 31, 2016 to ensure settings are correct for alerting
operations to leaks and spills within the limits of the probes when properly operated and calibrated. 
 When a visual alarm triggers, the
operator shall inspect that piece of equipment or area of the plant for any problems and take appropriate measures to stop or minimize the release and minimize further impacts (see Attachment B of this Plan). 

 
 2 Non-Segregable Areas are described in Facility Reports “Containment of Phosphoric Acid Product Spills and Leaks.”

Table of Contents

 The conductivity system shall be maintained in accordance with specific manufacturer
recommendations or acceptable industrial practices and updated as needed. Conductivity meters will be checked monthly and the instruments calibrated if necessary. The calibration dates and probe alarm limits shall be documented in the maintenance
management system that is in place at the time. Maintenance and calibration procedures are found in Attachment B of this Plan. 

1.5        Tracking/Recording 

AON shall be used to track leaks and spills and the remedial measures taken to address a leak or spill. The area management, engineering, and
environmental departments shall use AON to ensure the prompt and proper execution of remedial measures. When plant personnel identify a leak, spill or process upset (e.g. filtrate tank overflow), resulting in a release, appropriate remedial measures
shall be taken as outlined below. A record of the incident shall be entered within 24 hours of the incident into AON to log and track releases of Table 1 Materials. Supervisors shall be trained to enter incidents into AON. AON tracks specific
information including date and time of release, date and time of report, a description of the incident, volume of the material, type of material, and additional supporting information. AON generates emails to specific personnel that identify the
severity and location of the incident. Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill, except for minor leaks or spills that already have been remedied. 

1.6        Reporting, Recovery, and Remedial Measures

 Management and environmental staff shall be notified of leaks or spills with a reasonable potential to reach or exceed
the BMP Actionable Volume (Table 1) as quickly as possible in order to verify the volume of the leak or spill and ensure that it is properly reported, documented, and corrected pursuant to this BMP. 

Mosaic personnel are responsible for notifying the appropriate personnel immediately upon the identification of a leak or spill, except for
minor leaks or spills that already have been remedied. AON shall be used to track leaks and spills and the immediate actions taken to address a leak or spill. The area management, engineering, and environmental departments shall use AON to ensure
the prompt and proper execution of remedial measures. 

1.6.1            Non-Segregable Areas of the Phosphoric Acid Plants: 

1.6.1.1  Reporting 

Any leak or spill of FSA, sulfuric acid, SACS, PACS, FSACS or phosphoric acid into a non-segregable area, as described in
each Facility’s Facility Report, which is detected as a result of visual inspections, audible alarms, conductivity monitoring, or operational detections (e.g. pressure losses) must be logged into AON. See Section 1.6.1.2: Remedial
Measures, of this BMP. 
 If the leak or spill has the potential to exceed the BMP Actionable Volume (Table 1) in a
rolling 24-hour period, appropriate management and environmental staff shall be notified and the leak or spill shall be properly reported, documented, and corrected pursuant to this BMP.

If any leak or spill of a Table 1 Material into a non-segregable area, as described in each Facility’s Facility Report,
with a reasonable potential to approach a BMP Actionable Volume (Table 1) within any rolling 24-hour period is discovered, Mosaic will take the following measures: 
  

	 	1)	 Investigate potential release sources. 

  

	 	2)	 Address any issues found. 

  

	 	a.	 Stop the release if possible, such as by flow diversion or by closing the release gate. 

 

	 	b.	 Generate a work order if needed to correct the issue. 

 

	 	3)	 Document the release in AON. 

  

	 	4)	 Report the release to EPA, FDEP, or LDEQ pursuant with the Consent Decree. 

This BMP does not relieve Mosaic of its obligation to comply with any federal, state, or local laws applicable to such a
leak or spill. 
 1.6.2             Containable Impervious Areas: 

1.6.2.1  Reporting 

Any leak or spill of a Table 1 Material into a containable impervious area, as described in each Facility’s Facility
Report and identified in Figure 10 (Bartow), Figure 9 (New Wales), Figure 7 (Uncle Sam), and Figure 11 (Riverview), must be logged into AON but does not need to be reported to EPA if recovered to a tank containing the same chemical or the Big
Holding Tank (BHT), described in Section 6: Cleaning Solution System Operation, of this BMP. 
 1.6.2.2  Recovery and
Remedial Measures 
 Any leak or spill of a Table 1 Material into a containable impervious area, as described in each
Facility’s Facility Report and identified in Figure 10 (Bartow), Figure 9 (New Wales), Figure 7 (Uncle Sam), and Figure 11 (Riverview), shall be recovered back to a tank containing the same chemical or input into the BHT via sump pump, vacuum
truck, or other means or, if unrecoverable due to contamination or location of the spill, must be managed in compliance with the RCRA Requirements. This BMP does not relieve Mosaic of its obligation to comply with any other federal, state, or local
laws applicable to such a leak or spill. 
 1.6.3             Other Areas:

 1.6.3.1  Reporting

 SECTION 2:  PHOSPHORIC ACID PLANT CLEANING
PROCEDURES 
 2.1        General

 SACS, FSA, PACS, or FSACS are periodically used to wash lines, filters, or other equipment within the phosphoric acid
plant, including evaporation and clarification. The primary purpose for continuing to use SACS is to recover sulfate value and offset the amount of virgin sulfuric acid used. The primary purpose for continuing to use FSA and FSACS is to recover FSA
value. The primary purpose for using PACS is to recover P2O5 value. The recovery of these solutions will contribute to decreasing the
total dissolved solids in the Process Wastewater ponds. 
 SACS, FSA, FSACS and PACS shall be managed as shown in Diagram
1:    Big Holding Tank Cleaning Solution and Solids Management Plan. Following commencement of operations of the Big Holding Tank (BHT), no SACS or PACS shall be placed into the Phosphogypsum Stack System, other than
indirectly via the approved uses below. SACS PACS, FSA and FSACS shall be routed to the BHT (described in Section 7: Minimization of Operational Phosphoric Acid Inputs, of this Appendix) for consumption in the phosphoric acid plant so the BHT
Effluent’s value can be realized through the following uses described in each Facility’s Facility Report: 
  

	 	1.	 Added to the filter prior to the final cake wash to inhibit scale formation. The filtrate from this wash is sent as recycle acid to the reactor
(attack tank); or 

	 	2.	 Used as direct make up to the reactor attack tank; or 

	 	3.	 Added to the rock grinding circuit where it will ultimately end up in the slurry fed into the phosphoric acid reactor(s); or

	 	4.	 If the P2O5 content is at least
8%, placed in the evaporator feed tank(s) for P2O5 recovery. 

If for any reason the BHT Effluent is not recovered as outlined above, it must satisfy the RCRA land disposal restriction (LDR) standards
prior to discharge to the Phosphogypsum Stack System (see Diagram 1). 
 Following commencement of operations of the BHT, if FSA has been
transferred to BHT Recovery Units for sale or cleaning,3 no FSA or FSACS shall be placed into the Phosphogypsum Stack System from BHT Recovery Units, other than indirectly via the following: 

 

	 	1.	 Returned to the evaporator feed tank(s) that directly feed FSA-producing evaporators when FSA is being recovered for sale and/or internal
consumption; or 

	 	2.	 Sent to phosphoric acid reactors for reprocessing and recovery of FSA values; or 

	 	3.	 Sent to the BHT as described in Section VI (Compliance Projects) of the respective Facility’s Facility Report for recovery of FSA values; or

	 	4.	 Used as FSACS and then sent to the BHT for reprocessing and recovery of acid values. 

If for any reason FSA or FSACS from BHT Recovery Units is not recovered as outlined above, it must 

 
 3 FSA is not always recovered. When FSA is not being recovered for sale or cleaning, the gases pass through the Swift Tower to the barometric condenser, there is no recirculation of FSA through the
Swift Tower, and therefore FSA is not produced. Even when FSA is not being recovered, the FSA Seal Tank remains an essential part of the Phosphoric Acid Evaporator by sealing the Swift Tower downleg.

When SACS, PACS, or FSACS is used to clean lines and equipment, the cleaning solution shall be managed as shown in Diagram 1. 

2.4        Evaporator Cleaning – Upstream and
Grandfathered 
 Evaporators (including Swift Tower and FSA Seal Tank, if applicable) shall be washed using the following
procedure. Prior to the wash, evaporators shall be drained of phosphoric acid; the acid shall be recovered in the phosphoric acid production process. The wash shall be performed with hot cleaning solution, typically condensate, Phosphogypsum Stack
System Wastewater, Process Wastewater, SACS, or FSACS. The cleaning solution is circulated through the evaporator and various lines that require cleaning. All SACS, PACS, or FSACS shall be managed as shown in Diagram 1. 

Note:    If Phosphogypsum Stack System Wastewater, Process Wastewater, or NHACS is used, the cleaning solution(s)
may be input into Upstream Operations or sent to the Phosphogypsum Stack System. 

2.5        Phosphoric Acid Tank and Equipment Cleaning –
Upstream, Mixed-Use and 
 Grandfathered 

The following general steps shall be used in cleaning of units that are part of Upstream Operations, Mixed-Use Units, or Grandfathered Units,
or phosphoric acid tanks in the Phosphoric Acid Plant. The tanks shall be emptied by recovering as much phosphoric acid and as many solids as possible back into the phosphoric acid production process. The tanks shall then be washed with a cleaning
solution, including at times SACS. High pressure cleaning with NHACS or other mechanical means may be used to remove hard phosphogypsum scale and buildup or to strip rubber from the tank. Solids from these units may be transferred to the
Phosphogypsum Stack System. If Phosphogypsum Stack System Wastewater, Process Wastewater or NHACS is used to clean these tanks, such cleaning solutions may be input to Upstream Operations or sent to the Phosphogypsum Stack System. SACS, PACS, and
FSACS shall be managed as shown in Diagram 1. 

2.6        Phosphoric Acid Tank and Equipment Cleaning –
BHT Recovery Units 
 Following commencement of operations of the BHT, the following general steps shall be used in cleaning
of phosphoric acid tanks designated as BHT Recovery Units. The tanks shall be emptied by recovering as much phosphoric acid and as many solids as possible back into the phosphoric acid production process. The tanks shall then be washed with a
cleaning solution (SACS, PACS, FSACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). Liquids (including entrained solids) will be recovered to the BHT. Solids that are removed with high pressure cleaning with NHACS or by other
mechanical means will be dewatered. The liquid portion of the dewatered solids will be recovered to the BHT. If the dewatered solids are non-hazardous, they will be transferred to the Phosphogypsum Stack System. If they are hazardous, they will be
handled in compliance with the RCRA Requirements.

2.7        BHT/Pump Tank Cleaning – BHT Recovery Units

 Following commencement of operations of the BHT, the following general steps shall be used in cleaning of BHT(s) or any
pump tanks installed with the project for collecting cleaning solutions prior to returning to BHT. The tank(s) shall be emptied by recovering as much liquid and as many solids as possible back into the BHT or a backup BHT. The tank(s) shall then be
washed with a cleaning solution (SACS, PACS, FSACS, Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS) and the wash solution sent to the available BHT. 

Liquids (including entrained solids) will be recovered to the available BHT. Solids that are removed with high pressure cleaning with NHACS
or by other mechanical means will be dewatered. The liquid portion of the dewatered solids will be recovered to the available BHT. If the dewatered solids are non-hazardous, they will be transferred to the Phosphogypsum Stack System. If they are
hazardous, they will be handled in compliance with the RCRA Requirements. 

2.8        FSA Tank and Equipment Cleaning: BHT Recovery Units

 Following commencement of operations of the BHT, the following procedure shall be used for cleaning FSA tanks designated
as BHT Recovery Units in a Facility’s Facility Report. Transfer as much acid as possible from the tank into an available FSA tank. Wash out the remaining solids in the tank using NHACS. Liquids (including entrained solids) will be recovered to
the available BHT. Solids that are removed with high pressure cleaning with NHACS or by other mechanical means will be dewatered. The liquid portion of the dewatered solids will be recovered to the available BHT. If the dewatered solids are
non-hazardous, they will be transferred to the Phosphogypsum Stack System. If they are hazardous, they will be handled in compliance with the RCRA Requirements. 

2.9        Rotating Pan Filter Cleaning 

An aqueous cleaning solution is used to wash filter pans. High pressure cleaning with freshwater, aqueous cleaning solution or mechanical
equipment may be used to remove hard phosphogypsum scale and buildup. When Phosphogypsum Stack System Wastewater, Process Wastewater or NHACS is used to clean the filter pans, such cleaning solutions may be input to Upstream Operations or sent to
the Phosphogypsum Stack System. If SACS, PACS, or FSACS are used to wash filter pans, such solutions shall be sent to the BHT. Phosphogypsum solids removed by high pressure cleaning with NHACS or other mechanical means shall be transferred to the
Phosphogypsum Stack System. 
 2.10        Phosphoric Acid
Reactor (Attack Tank) Cleaning 
 The following general steps shall be used in the cleaning of phosphoric acid attack tanks
(phosphoric acid reactors). Empty the attack tank by recovering phosphoric acid and solids back to the process. The attack tank may then be washed with a cleaning solution. High pressure cleaning with NHACS or other mechanical means may be used to
remove hard phosphogypsum scale and buildup. Solids removed using Phosphogypsum Stack System Wastewater, Process Wastewater or NHACS or by mechanical means shall be transferred to the Phosphogypsum Stack System. If Phosphogypsum Stack System

 SECTION 3:  GRANULATION PLANTS CLEANING PROCEDURES5 

3.1        General 

Mosaic’s intent is to minimize losses and to conserve and recover resources whenever feasible. Solutions and solids generated from
cleaning granulation equipment other than BHT Recovery Units as described in the Facility’s Facility Report shall either be recovered in the granulation process or characterized to determine if they are hazardous under the RCRA Requirements for
corrosivity (pH £ 2 or pH 3 12.5) and/or toxicity (Table 2). If the materials are not recovered to the granulation process and are hazardous, they shall be
handled according to the RCRA Requirements. If these materials are not recovered to the granulation process and are non-hazardous, they can be discharged to the Phosphogypsum Stack System. 

3.2        Line Cleaning 

All lines within the granulation plant shall be washed with an aqueous cleaning solution (i.e., Process Wastewater, Phosphogypsum Stack
Water, NHACS, SACS, PACS, FSACS, FSA or GHT Effluent). All cleaning solutions that enter the boundary of the granulation plant shall be handled according to Section 3.1: General, of this BMP. 

3.3        Phosphoric Acid Tank Cleaning (BHT Recovery Units)

 Following commencement of operations of the BHT, the following general steps shall be used in the cleaning of any
phosphoric acid storage tank in the granulation plants (BHT Recovery Units). Empty the tank by feeding the remaining acid to the Granulation process or recovering phosphoric acid back to the phosphoric acid clarification process or another
phosphoric acid tank within the Granulation area. Wash the tank with an aqueous cleaning solution (i.e., Process Wastewater, Phosphogypsum Stack Water, NHACS, SACS, PACS, FSACS, FSA or BHT Effluent) if needed. Fill the tank with cleaning solution
and recirculate to facilitate cleaning for an appropriate period of time (typically 12-48 hours), until the scale is adequately removed. The wash may be repeated multiple times until adequately cleaned, and the wash solution (including entrained
solids) sent to the BHT. Solids that are removed with high pressure cleaning with NHACS or by other mechanical means will be dewatered. The liquid portion of the dewatered solids will be recovered to the BHT. If the dewatered solids are
non-hazardous, they will be transferred to the Phosphogypsum Stack System. If they are hazardous, they will be handled in compliance with the RCRA Requirements. 

At Bartow, ammonia may be added as a scale softening agent to DAP Pond water, Phosphogypsum Stack System Wastewater, or Process Wastewater
and the resulting cleaning solution is used to clean phosphoric acid storage tanks in the granulation plant. This non-hazardous spent wash solution shall only be recovered to the DAP process pond. 

3.4        Acid Scrubber, Reactor and Tailgas Scrubber System
Cleaning - GHT Recovery Units 
 Granulation plant scrubbers and reactors are cleaned with a cleaning solution based on the
frequency of scale buildup. After recovering scrubber liquid to the process, the scrubbers and reactors shall be filled and recirculated with the cleaning solution until scale is adequately removed. SACS is normally

used as a cleaning solution, but Process Wastewater, Phosphogypsum Stack System Wastewater, or NHACS (including water from the DAP Pond or fresh water) can be used. Following commencement of
operations of the Granular Holding Tank (GHT), the resulting stream shall be sent to the GHT. High pressure cleaning with NHACS or other mechanical means may be used to remove hard scale and buildup or to strip rubber from the equipment. Solids that
are removed from the Tailgas Scrubber system will be characterized and handled in compliance with the RCRA Requirements. 
 
3.5        Granulation Dry Side Equipment Cleaning - GHT Recovery Units 
 The
wash solution, such as Process Wastewater, DAP Pond water, Phosphogypsum Stack Wastewater, or NHACS is collected either in the Acid Scrubber or the Reactor and a continuous flow is sent to the Dry Side Equipment, such as the granulator, dryer,
cooler, elevators, screens, milling equipment and the associated piping. The cooler may be washed as part of the Dry Side Equipment wash or separately. High pressure cleaning with NHACS or other mechanical means may be used to remove hard scale.
Following commencement of operations of the GHT, liquids (including entrained solids) will be recovered to the GHT. Solids that are removed with high pressure cleaning or mechanical means will be dewatered, if needed. Following commencement of
operations of the GHT, any liquid portion of these solids will be recovered to the GHT. The solids will be recovered back to the granulation process through either the dry reclaim system or the re-slurry system. 

3.6        GHT Cleaning and Non-Routine Transfer Situations

Following commencement of operations of the GHT, the following general steps shall be used in cleaning of the GHT(s) and the Riverview and
New Wales GHT intermediate tanks. The tanks shall be emptied by recovering as much liquid (with entrained solids) as possible back into the granulation process and/or the BHT. Any residual volume that is hazardous only for RCRA corrosivity (pH £2) and cannot be recovered into the granulation process may be transferred to the BHT not more than two times per calendar year. The GHT shall then be washed with a cleaning solution (SACS, PACS, Process
Wastewater, Phosphogypsum Stack System Wastewater, or NHACS). If the wash solution is hazardous only for RCRA corrosivity (pH £2), it may be transferred to the BHT; not more than two times per calendar
year. If the solution is non-hazardous, it can be transferred to the BHT or sent to the Phosphogypsum Stack System. 

3.6.2      Non-Routine Situations 

In non-routine situations, such as mechanical failure in the Granulation Plant, unexpected plant outages, electrical power failures,
hurricanes or similar weather events or unexpected problems during startups, Mosaic may transfer GHT Effluent that is hazardous only for RCRA corrosivity (pH £2) from the GHT to the BHT(s) as described in
each Facility’s Facility Report. 
 3.7        Wash
Down 
 NHACS (including fresh water or DAP Pond water) may be used for wash down of the floors, conveyor belts, and other
equipment within the granulation plant. If non-hazardous, the resulting streams may be transferred to the Phosphogypsum Stack System or the DAP Pond. If the resulting streams are hazardous, they will be recovered to the GHT or characterized and
handled in compliance with the RCRA Requirements.

 4.7        Maintenance Department Responsibilities 

The Maintenance Department personnel will be responsible for repairs and maintenance to faulty equipment. If the leak or spill is the result
of a mechanical failure, the appropriate operations personnel shall notify the Maintenance Department of the condition and shall initiate a work order request for correction of the problem. The Maintenance Department shall be responsible for timely
completion of leak repairs. Maintenance work requests and their status are tracked in a computerized maintenance management system (currently MAXIMO). When the Maintenance Department completes the repairs, the appropriate operations personnel shall
be notified. 
 SECTION 5:  GRANULATION PLANT SECONDARY SCRUBBERS7 
 The granulation plants utilize secondary scrubbers. These secondary
scrubbers are utilized on the reactor, granulator, dryer, equipment, and/or cooler scrubbing circuits for fluoride scrubbing. The New Wales site utilizes once through Process Wastewater as a scrubbing medium. Pursuant to the Consent Decree, the New
Wales granulation plants shall eliminate the use of Process Wastewater as a scrubber medium. Mosaic may continue to discharge Process Wastewater used in the aforementioned scrubbers within the New Wales granulation plants to the Phosphogypsum Stack
System until the referenced projects described in Appendix 6 (Project Narrative & Compliance Schedules) of the Consent Decree are completed. 
 SECTION 6:  
CLEANING SOLUTION SYSTEM OPERATION 
 6.1        
Phosphoric Acid Plant Areas 
 The cleaning solution system shall be composed of a containment system to capture and return
cleaning solution streams from Upstream, Mixed-Use, Grandfathered, and BHT Recovery Units, including SACS, PACS, FSA, and FSACS to the BHT(s). Mosaic also may recover spills and leaks of phosphoric acid, sulfuric acid, FSA, SACS, PACS, FSACS, or BHT
Effluent; or NHACS, Process Wastewater, Phosphogypsum Stack System Wastewater, when mixed with any of the preceding solutions due to spills, leaks, or cleaning of leaks and spills, in containable impervious areas to the BHT(s). The BHT(s) shall in
turn return the spills, leaks, and cleaning solution streams to the phosphoric acid production process, where their values can be realized through the methods outlined in Section 2: Phosphoric Acid Plant Cleaning Procedures, of this BMP. All
inputs to and effluents from the BHT are illustrated in Diagram 2.

 6.2        Granulation
Areas9 
 The granulation containment pads shall be designed to collect
rainfall, spills, leaks, and cleaning solutions within plant areas. The collection sumps for these containment pads shall pump to the granulation plant scrubbers, re-slurry tank, GHT or, if non-hazardous, may be discharged to a permitted National
Pollutant Discharge Elimination System (NPDES) outfall. The sumps will be designed with pH probes that will allow storm water run-off during high rainfall to be diverted to the Phosphogypsum Stack System if pH > 2.0 or to a permitted NPDES
outfall. This will eliminate excessive rain water getting into the GHT, diluting it and also leading to the tank level being high. The granulation plant acid scrubbers and re-slurry tank are designed to recover fertilizer materials, product and raw
materials for consumption in the granulation process. 
 Cleaning solutions in the Granulation area (except for cleaning solutions from
BHT Recovery Units) shall be managed as follows: 

	 	•	 	 If the resulting stream from the cleaning process is non-hazardous, the solution may be discharged directly to the Phosphogypsum Stack System or
recovered in the granulation process via the GHT. 

	 	•	 	 If the resulting stream is hazardous, then the resulting solution shall be recovered in the granulation process via the GHT for recovery of
product value. 

 Mosaic may transfer cleaning solution from GHT to BHT as specified in the Facilities’ Facility
Reports.

 SECTION 7:  MINIMIZATION OF OPERATIONAL PHOSPHORIC
ACID INPUTS 
 7.1        Background

 During normal operation of the Phosphoric Acid Plants, various activities may result in the operational input of
phosphoric acid to impervious areas within the battery limits of the Phosphoric Acid Plants or to the Phosphogypsum Stack System. These activities include sample collection, slide gate valve operation, clearing plugged piping or process equipment,
and similar routine operations. Operators shall minimize the volume of such phosphoric acid inputs by releasing only the amount of acid necessary in order to accomplish the task and recover acid loss where practicable. Intermittent operational
inputs of phosphoric acid to impervious areas or the Phosphogypsum Stack System are unavoidable and shall not be considered malfunctions, leaks, or spills, unless the volume from one of these inputs to the Phosphogypsum Stack System exceeds the BMP
Actionable Volume (Table 1). Any continuing release resulting from these activities may indicate the need for maintenance activity and shall be entered into AON and the computerized maintenance management system (currently MAXIMO) for correction.

 7.2        Operational Input Minimization

 7.2.1    Sample Collection 

Samples of phosphoric acid or reactor slurry collected for purposes of plant process control shall be returned to the process. 

7.2.2    Clarifier/Valve/Line Operational Releases 

Operational inputs of phosphoric acid from clarifier unplugging, valve operation and line unplugging shall be minimized to the extent
practicable, releasing only the amount of acid necessary out of the primary containment area in order to accomplish the task and recovery where practicable. 

7.3        Response 

7.3.1    Releases Outside Containment Areas 

All reasonable measures shall be taken to avoid releases of phosphoric acid outside of plant containment areas. This BMP does not relieve
Mosaic of its obligation to comply with any federal, state, or local laws applicable to such a release. 

7.3.2    Emergency Response 

Mosaic’s Spill Reporting Policy and Procedure also contains guidance for the management of environmental spills or releases that may
require emergency response measures.

8.2        Tanks 

The mechanical integrity of phosphoric acid tanks shall be managed in accordance with the current version of Mosaic’s Liquid Storage
Tanks, Secondary and Impermeable Containment Program. 
 Phosphoric acid storage tanks that are regulated by Florida Department of
Environmental Protection (FAC § 62-762) shall be inventoried. Phosphoric acid storage tanks that are not regulated by Florida Department of Environmental Protection (FAC § 62-762) or Louisiana Department of Environmental Quality shall be
inventoried and inspected in accordance with Mosaic’s Liquid Storage Tanks, Secondary and Impermeable Containment Program. 

8.3        Concrete Acid Pads 

The mechanical integrity of concrete acid pad containment systems for phosphoric acid leaks or spills shall be inspected and evaluated
annually in accordance with requirements contained in Mosaic’s Liquid Storage Tanks, Secondary and Impermeable Containment Program. 

Mosaic shall be responsible for conducting annual inspections of concrete acid pads in the Phosphoric Acid and Granulation Plant areas.
Visual inspection will be for the following indicators: erosion/holes, protective liner damage and/or floor drainage irregularities. Inspection results shall be documented in a report with recommendations, reviewed with appropriate management, and
implemented as needed. 
 When Mosaic determines it is necessary to replace or partially replace concrete acid pads in the Phosphoric Acid
and Granulation Plant areas, under-slab liners shall be installed in the affected area. 

8.4        Sumps and Ditches 

The mechanical integrity of sumps and ditches used in washing circuits and collection of phosphoric acid leaks or spills shall be managed as
specified in Mosaic’s Liquid Storage Tanks and Secondary Containment Program. 
 Mosaic shall be responsible for conducting
inspections of sumps and ditches whenever major plant outages or turnarounds in the phosphoric acid and granulation plant areas allow for the sumps to be drained (approximately once every 5 years). Inspection results shall be documented in a report
with recommendations and reviewed with appropriate management and implemented as needed.

PHOSPHOGYPSUM STACK SYSTEM ALTERNATIVE 

LINER REQUIREMENTS 
  

 
  

MOSAIC UNCLE SAM 
  

 
 Appendix 1 of this Consent Decree sets forth
requirements for lining Phosphogypsum Stack Systems within five years of the Effective Date of this Consent Decree as a means of reducing or eliminating contamination migrating from such stacks. On January 6, 2011 and November 7, 2011,
Mosaic submitted demonstration documents titled “Overview of Seepage Control Features and Projected Groundwater Quality Impacts for Mosaic Fertilizer, LLC Uncle Sam Phosphogypsum Stack System,” hereafter referred to as the “Uncle Sam
Demonstration,” proposing that alternate means of containment can meet the Environmental Protection Agency’s (EPA) and the Louisiana Department of Environmental Quality’s (LDEQ) environmental protection goals and obviate the
requirement of Appendix 1, Attachment D, Section VII to, within five years of the Effective Date, line existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment C, Section VI, or within five years of the Effective Date,
close existing unlined Phosphogypsum Stack Systems in accordance with Appendix 1, Attachment D. This Appendix identifies the specific Phosphogypsum Stack System components that, subject to the terms of the Consent Decree (including Paragraph
22(a)(2)), the United States and LDEQ have determined either meet the liner design standards of Appendix 1, Attachment C, Section VI, or are considered an acceptable alternative to those standards. The United States’ and LDEQ’s acceptance
of the Uncle Sam Demonstration for this purpose does not bind the United States or LDEQ to the factual assertions and conclusions of the Demonstration. This Appendix also identifies the specific Phosphogypsum Stack System components that either meet
the closure design standards of Appendix 1, Attachment D or that are considered to be an acceptable alternative to the closure design standards of Appendix 1, Attachment D. 
  

General Demonstration of Environmental Protectiveness 

The active Uncle Sam Phosphogypsum Stack System and inactive system (including non-process water ponds) consist of Inactive Stacks 1- 3 (Stacks 1 -3), a
110-Acre Reservoir, Active Gypsum Stack Number 4 (Stack 4), Stack 4 Side Slopes (closed), Stack 4 Side Slopes (active), and a Cooling Pond System. The Cooling Pond System consists of the Active Toe Ditch on the north side of Stack 4, a
two-compartment 30-acre Active Reservoir, a water return ditch from the 30-acre Active Reservoir to Dunn’s Dam, and Return Flume into the 04 Basin, and the 04 Basin (Figure 1). The Cooling Pond System is used for process water management, as
well as circulation and cooling of process water, and receives incidental discharges of gypsum slurry. Other water bodies exist at Uncle Sam that are not part of the Phosphogypsum Stack System.

 Mosaic Uncle Sam 

Alternative Liner Requirements 

Appendix 7 
  

 The key components of Mosaic’s Demonstration rely mostly upon an engineered compacted clay cut-off
trench keyed into the natural confining unit and a soil bentonite cut-off wall as a seepage prevention features, and certain synthetic liners yet to be installed, as summarized below. 

Cut-Off Features 
 The entire Phosphogypsum Stack System,
except for the Return Flume and 04 Basin, are encompassed by a compacted clay perimeter levee with a compacted clay key (cut-off trench) that extends 4 to 8 feet into the natural ground clay confining unit and mitigates lateral seepage from the
stack system. 
 In addition to the compacted clay key, the southern portion of Inactive Stacks 1-3 has a soil bentonite cut-off wall keyed 18 feet into the
natural ground clay confining unit. 
 Synthetic Liners 

In addition to the clay cut-off trench, Mosaic plans to vertically expand and line the Phosphogypsum Stack System (excluding the Active Toe Ditch, 30-Acre
Active Reservoir, and the water return ditch from the 30-Acre Active Reservoir to Dunn’s Dam and excluding the 110-Acre Reservoir and existing gypsum stack slopes) in two phases (See Figure 2 illustrated in orange/ Compliance Project 9). 

Phase 1 
 Mosaic will raise Stack 4 to an interim average
elevation of 200 feet (MSL) and then begin to install an intermediate liner on Stacks 1-3 no later than 1 year after that milestone is reached (i.e., before or about 2016 depending on plant production and water balance considerations). The liner
will comport with the liner requirements of Appendix 1, Attachment C, but with placement of sedimented gypsum over the liner instead of a mechanically compacted phosphogypsum component. 

Phase 2 
 Mosaic will begin the vertical expansion of the
newly lined Stacks 1-3 within 18 months after initiating liner installation and will then install an intermediate liner on Stack 4 no later than one year after the Stacks 1-3 vertical expansion reaches an average elevation of 200 feet (MSL) that
comports with the liner requirements of Appendix 1, Attachment C, but with placement of sedimented phosphogypsum over the liner instead of a mechanically compacted phosphogypsum component. Phase 2 will include lining the Decant Ditch. Phosphogypsum
will continue to be deposited on Stacks 1-3 up to an interim height of 200 feet so that Stacks 1-3 and 4 are at equivalent heights. Mosaic will then begin depositing Phosphogypsum on the combined lined Stacks 1-4.

 The following components or former components designated in orange in Figure 3 of Mosaic’s Stack System or other adjacent
non-process ponds are not subject to the liner requirements of Appendix 1, Attachments C and D, as long as they do not hereafter receive Process Wastewater or Phosphogypsum. 

1) Inactive Stack 4 Side Slopes 
 2) Inactive Stacks 1-3 

The following components of Mosaic’s Stack System designated in orange in Figure 4 have existing engineered seepage control features that deviate from
the Government’s liner design standards of Appendix 1, Attachment C, Section VI but are determined to be environmentally protective and thus deemed to meet the requirements of a lined system, consistent with Appendix 1, Attachment C,
Section VI (i.e. no additional equivalency determination necessary). 
 1) Active Toe Ditch 

2) 30-Acre Active Reservoir- both compartments 
 3) Water return
ditch from the 30-acre Active Reservoir to Dunn’s Dam 
 The following components of Mosaic’s Stack System designated in orange in Figure 5
deviate from the Government’s liner design standards of Appendix 1, Attachment C, Section VI but are deemed environmentally protective and equivalent to the requirements of Appendix 1, Attachment C, Section VI (i.e. no additional equivalency
determination necessary) upon completion of the Phase 1 and Phase 2 lining projects described above. 
 1) Stack 4 (including the Decant Ditch) 

2) Stacks 1-3 Vertical Expansion 
 The following components of
Mosaic’s Stack System designated in orange in Figure 6 are not contained within the clay cut-off trench and must be lined and/or replaced with a piped system as may be appropriate pursuant to the permit applications Mosaic will submit for LDEQ
approval under Compliance Schedule Projects 8 (Lining of Active Water Return Flume) and 9 (Lining of the 04 Basin). Once Mosaic implements the LDEQ approved permit modifications, the following components will be environmentally protective, and thus
they are considered to be acceptable alternatives to the requirements of Appendix 1, Attachment C, Section VI (i.e., no additional equivalency determination necessary). 

1) Return Flume from Dunn’s Dam into the 04 Basin (Compliance Schedule, Project 8) 

2) The 04 Basin (Compliance Schedule, Project 9)
