VI. Statutory and Executive Order 
Reviews 
Under the CAA, the Administrator is 
required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action: 
•Is not a ‘‘significant regulatory 
action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); 
•does not impose an information 
collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); 
•is certified as not having a 
significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); 
•does not contain any unfunded 
mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); 
•does not have Federalism 
implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); 
•is not an economically significant 
regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); 
•is not a significant regulatory action 
subject to Executive Order 13211 (66 FR 28355, May 22, 2001); •is not subject to requirements of 
Section 12(d) of the National 
Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and 
•does not provide the EPA with the 
discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). 
In addition, this proposed rule does 
not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply on any Indian reservation land in Oregon or any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction.

Significant New Use Rule on Certain 
Chemical Substances 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : EPA is proposing significant 
new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for three chemical substances which were the subject of premanufacture notices (PMNs). This action would require persons who intend to manufacture (defined by statute to include import) or 
process any of the chemical substances for an activity that is designated as a significant new use by this proposed rule to notify EPA at least 90 days before commencing that activity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit the activity before it occurs. 
DATES : Comments must be received on 
or before May 13, 2016.

SUPPLEMENTARY INFORMATION : 
I. General Information 
A. Does this action apply to me? 
You may be potentially affected by 
this action if you manufacture, process, 
or use the chemical substances contained in this proposed rule. The following list of North American Industrial Classification System (NAICS) codes is not intended to be exhaustive, but rather provides a guide to help readers determine whether this document applies to them. Potentially affected entities may include: 
Manufacturers (including importers) 
or processors of one or more subject chemical substances (NAICS codes 325 and 324110), e.g., chemical 
manufacturing and petroleum refineries. 
This action may also affect certain 
entities through pre-existing import certification and export notification rules under TSCA. Chemical importers are subject to the TSCA section 13 (15 U.S.C. 2612) import certification requirements promulgated at 19 CFR 12.118 through 12.127 and 19 CFR 127.28. Chemical importers must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA. Importers of chemicals subject to these SNURs must certify their compliance with the SNUR requirements. The EPA policy in support of import certification appears at 40 CFR part 707, subpart B. In addition, any persons who export or intend to export a chemical substance to a proposed or final rule are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see § 721.20), and must comply with the export notification requirements in 40 CFR part 707, subpart D. 
B. What should I consider as I prepare 
my comments for EPA? 
1. Submitting CBI. Do not submit this 
information to EPA through regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD–ROM that you mail to EPA, mark the outside of the disk or CD–ROM as CBI and then identify electronically within the disk or CD–ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 
2. Tips for preparing your comments. 
When preparing and submitting your comments, see the commenting tips at http://www.epa.gov/dockets/comments.html. 
II. Background A. What action is the agency taking? 
EPA is proposing these SNURs under 
TSCA section 5(a)(2) for three chemical 
substances which were the subject of PMNs P–15–221, P–15–247, and P–15– 278. These SNURs would require persons who intend to manufacture or process any of these chemical substances for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity. In accordance with the procedures at § 721.160(c)(3)(i), in the Federal Register publication of October 2, 2015 (80 FR 59583) (FRL– 9933–30) EPA issued direct final SNURs on these chemical substances, which are the subject of PMNs. EPA received notices of intent to submit adverse comments on these SNURs. Therefore, as required by § 721.160(c)(3)(ii), EPA withdrew the direct final SNURs in the Federal Register of November 20, 2015 (80 FR 72592) (FRL–9936–98), and is now issuing this proposed rule on these three chemical substances. The records for the direct final SNURs on these three chemical substances were established as docket EPA–HQ–OPPT–2015–0388. Those records include information considered by the Agency in developing the direct final rule. While notices of intent to submit adverse comments were received during the direct final rule 
phase, no substantive comments were submitted. EPA awaits the adverse comments during the open comment period for this proposed rule. 
B. What is the agency’s authority for 
taking this action? 
Section 5(a)(2) of TSCA (15 U.S.C. 
2604(a)(2)) authorizes EPA to determine that a use of a chemical substance is a ‘‘significant new use.’’ EPA must make this determination by rule after considering all relevant factors, including the four bulleted TSCA section 5(a)(2) factors listed in Unit III. Once EPA determines that a use of a chemical substance is a significant new use, TSCA section 5(a)(1)(B) requires persons to submit a significant new use notice (SNUN) to EPA at least 90 days before they manufacture or process the chemical substance for that use. Persons who must report are described in § 721.5. 
C. Applicability of General Provisions 
General provisions for SNURs appear 
in 40 CFR part 721, subpart A. These 
provisions describe persons subject to the rule, recordkeeping requirements, exemptions to reporting requirements, and applicability of the rule to uses occurring before the effective date of the final rule. Provisions relating to user fees appear at 40 CFR part 700. According to § 721.1(c), persons subject to these SNURs must comply with the same SNUN requirements and EPA regulatory procedures as submitters of PMNs under TSCA section 5(a)(1)(A). In particular, these requirements include the information submission requirements of TSCA section 5(b) and 5(d)(1), the exemptions authorized by TSCA section 5(h)(1), (h)(2), (h)(3), and (h)(5), and the regulations at 40 CFR part 720. Once EPA receives a SNUN, EPA may take regulatory action under TSCA section 5(e), 5(f), 6, or 7 to control the activities for which it has received the SNUN. If EPA does not take action, EPA is required under TSCA section 5(g) to explain in the Federal Register its reasons for not taking action. 
III. Significant New Use Determination 
Section 5(a)(2) of TSCA states that 
EPA’s determination that a use of a 
chemical substance is a significant new use must be made after consideration of all relevant factors, including: 
•The projected volume of 
manufacturing and processing of a chemical substance. 
•The extent to which a use changes 
the type or form of exposure of human beings or the environment to a chemical substance. 
VerDate Sep<11>2014 14:59 Apr 12, 2016 Jkt 238001 PO 00000 Frm 00074 Fmt 4702 Sfmt 4702 E:\FR\FM\13APP1.SGM 13APP1jstallworth on DSK7TPTVN1PROD with PROPOSALS21832 Federal Register / Vol. 81, No. 71 / Wednesday, April 13, 2016 / Proposed Rules 
•The extent to which a use increases 
the magnitude and duration of exposure 
of human beings or the environment to a chemical substance. 
•The reasonably anticipated manner 
and methods of manufacturing, processing, distribution in commerce, and disposal of a chemical substance. 
In addition to these factors 
enumerated in TSCA section 5(a)(2), the statute authorized EPA to consider any other relevant factors. 
To determine what would constitute a 
significant new use for the chemical substances that are the subject of these SNURs, EPA considered relevant information about the toxicity of the chemical substances, likely human exposures and environmental releases associated with possible uses, and the four bulleted TSCA section 5(a)(2) factors listed in this unit. 
IV. Substances Subject to This Proposed 
Rule 
EPA is proposing significant new use 
and recordkeeping requirements for three chemical substances in 40 CFR part 721, subpart E. In this unit, EPA provides the following information for each chemical substance: 
•PMN number. 
•Chemical name (generic name, if 
the specific name is claimed as CBI). 
•Chemical Abstracts Service (CAS) 
Registry number (assigned for non- confidential chemical identities). 
•Public comments and EPA’s 
response to comments on the three direct final SNURs 
•Basis for the TSCA non-section 5(e) 
SNURs (i.e., SNURs without TSCA 
section 5(e) consent orders). 
•Tests recommended by EPA to 
provide sufficient information to evaluate the chemical substance (see Unit VII. for more information). 
•CFR citation assigned in the 
regulatory text section of this proposed rule. 
The regulatory text section of this 
proposed rule specifies the activities designated as significant new uses. Certain new uses, including production volume limits (i.e., limits on 
manufacture volume) and other uses designated in this proposed rule, may be claimed as CBI. 
PMN Number P–15–221 
Chemical name: Isocyanate 
prepolymer (generic). 
CAS number: Claimed confidential. 
Basis for action: The PMN states that 
the generic (non-confidential) use of the 
substance will be as ingredient in an industrial adhesive. Based on Structure Activity Relationship (SAR) analysis of test data on analogous diisocyanates, EPA identified concerns for irritation 
and sensitization to the skin and lungs. As described in the PMN, EPA does not expect significant occupational dermal or inhalation exposure due to use of adequate personal protective equipment and consumer exposures are not expected as the PMN substance is not used in consumer products. Therefore, EPA has not determined that the proposed manufacture, processing, or use of the substance may present an unreasonable risk. EPA has determined, however, that any use of the substance without a National Institute for Occupational Safety and Health (NIOSH)-certified particulate respirator with an Assigned Protection Factor (APF) of at least 10 where there is a potential for inhalation exposure, or any use in consumer products may cause serious health effects. Based on this information, the PMN substance meets the concern criteria at § 721.170(b)(3)(ii). 
Recommended testing: EPA has 
determined that the results of a skin sensitization test (OPPTS Test Guideline 870.2600) and a 90-day subchronic inhalation toxicity test (OPPTS Test 
Guideline 870.3465) would help characterize the human health effects of the PMN substance. 
CFR Citation: 40 CFR 721.10871. 
PMN Number P–15–247 
Chemical name: Methylene 
diisocyanate polymer with diols and triols (generic). 
CAS number: Claimed confidential. 
Basis for action: The PMN states that 
the generic (non-confidential) use of the 
substance will be as an industrial adhesive. Based on SAR analysis of test data on analogous diisocyanates, EPA identified concerns for respiratory and dermal sensitization and lung and mucous membrane irritation based on the isocyanate moiety. As described in the PMN, EPA does not expect significant occupational dermal or inhalation exposure due to use of adequate personal protective equipment and consumer exposures are not expected as the PMN substance is not used in consumer products. Therefore, EPA has not determined that the proposed manufacture, processing, or use of the substance may present an unreasonable risk. EPA has determined, however, that any use of the substance without a NIOSH-certified particulate respirator with an APF of at least 10 where there is a potential for inhalation exposure, or any use in consumer products, may cause serious health effects. Based on this information, the PMN substance meets the concern criteria at § 721.170(b)(3)(ii). Recommended testing: EPA has 
determined that the results of a skin 
sensitization test (OPPTS Test Guideline 870.2600) and a 90-day subchronic inhalation toxicity test (OPPTS Test Guideline 870.3465) would help characterize the human health effects of the PMN substance. 
CFR Citation: 40 CFR 721.10873. 
PMN Number P–15–278 
Chemical name: Polymer of 
isophorone diisocyanate and amine- terminated propoxylatedpolyol (generic). 
CAS number: Claimed confidential. 
Basis for action: The PMN states that 
the generic (non-confidential) use of the 
substance will be as a crosslinker. Based on analogous diisocyanates, EPA identified concerns for potential dermal and respiratory sensitization from dermal and inhalation exposures and for pulmonary toxicity from inhalation exposure to the PMN substance when the average molecular weight is below 2,500 daltons and any molecular weight species below 1,000 daltons is present. EPA does not expect significant exposures from the form of the PMN substance as described in the PMN. Therefore, EPA has not determined that the proposed manufacture of the substance may present an unreasonable risk. EPA has determined, however, that 
any manufacture of the PMN substance with an average molecular weight of below 2,500 daltons and with any molecular weight species below 1,000 daltons may cause serious health effects. Based on this information, the PMN substance meets the concern criteria at § 721.170(b)(3)(ii). 
Recommended testing: EPA has 
determined that the results of a skin sensitization test (OPPTS Test Guideline 870.2600) and a 90-day subchronic inhalation toxicity test (OPPTS Test Guideline 870.3465) would help characterize the human health effects of the PMN substance. 
CFR Citation: 40 CFR 721.10874. 
V. Rationale and Objectives of the Proposed Rule 
A. Rationale 
During review of the PMNs submitted 
for the chemical substances that are 
subject to these SNURs, EPA determined that one or more of the criteria of concern established at § 721.170 were met. For additional discussion on these chemical substances, see Units II. and IV. of this proposed rule. 
B. Objectives 
EPA is proposing these SNURs for 
specific chemical substances which 
VerDate Sep<11>2014 14:59 Apr 12, 2016 Jkt 238001 PO 00000 Frm 00075 Fmt 4702 Sfmt 4702 E:\FR\FM\13APP1.SGM 13APP1jstallworth on DSK7TPTVN1PROD with PROPOSALS21833 Federal Register / Vol. 81, No. 71 / Wednesday, April 13, 2016 / Proposed Rules 
have undergone premanufacture review 
because the Agency wants to achieve the following objectives with regard to the significant new uses designated in this proposed rule: 
•EPA would receive notice of any 
person’s intent to manufacture or process a listed chemical substance for the described significant new use before that activity begins. 
•EPA would have an opportunity to 
review and evaluate data submitted in a SNUN before the notice submitter begins manufacturing or processing a listed chemical substance for the 
described significant new use. 
•EPA would be able to regulate 
prospective manufacturers or processors of a listed chemical substance before the described significant new use of that chemical substance occurs, provided that regulation is warranted pursuant to TSCA sections 5(e), 5(f), 6, or 7. 
Issuance of a SNUR for a chemical 
substance does not signify that the chemical substance is listed on the TSCA Chemical Substance Inventory (TSCA Inventory). Guidance on how to determine if a chemical substance is on the TSCA Inventory is available on the Internet at https://www.epa.gov/tsca- inventory. 
VI. Applicability of the Proposed Rule 
to Uses Occurring Before the Effective Date of the Final Rule 
To establish a significant new use, 
EPA must determine that the use is not ongoing. The chemical substances subject to this proposed rule have undergone premanufacture review. In cases where EPA has not received a notice of commencement (NOC) and the chemical substance has not been added to the TSCA Inventory, no person may commence such activities without first submitting a PMN. Therefore, for chemical substances for which an NOC has not been submitted EPA concludes that the designated significant new uses are not ongoing. 
When chemical substances identified 
in this proposed rule are added to the TSCA Inventory, EPA recognizes that, before the rule is effective, other persons might engage in a use that has been identified as a significant new use. The identities of the three chemical substances subject to this proposed rule have been claimed as confidential and EPA has received no post-PMN bona fide submissions (per §§ 720.25 and 
721.11). Based on this, the Agency believes that it is highly unlikely that any of the significant new uses described in the regulatory text of this proposed rule are ongoing. 
Therefore, EPA designates April 13, 
2016 as the cutoff date for determining whether the new use is ongoing. Persons who begin commercial manufacture or processing of the chemical substances for a significant new use identified as of that date would have to cease any such activity upon the effective date of the final rule. To resume their activities, these persons would have to first comply with all applicable SNUR notification requirements and wait until the notice review period, including any extensions, expires. If such a person met the conditions of advance compliance under § 721.45(h), the person would be considered exempt from the requirements of the SNUR. Consult the Federal Register document of April 24, 1990 (55 FR 17376) for a more detailed discussion of the cutoff date for ongoing uses. 
VII. Test Data and Other Information 
EPA recognizes that TSCA section 5 
does not require developing any 
particular test data before submission of a SNUN. The two exceptions are: 
1. Development of test data is 
required where the chemical substance subject to the SNUR is also subject to a test rule under TSCA section 4 (see TSCA section 5(b)(1)). 
2. Development of test data may be 
necessary where the chemical substance has been listed under TSCA section 5(b)(4) (see TSCA section 5(b)(2)). 
In the absence of a TSCA section 4 
test rule or a TSCA section 5(b)(4) listing covering the chemical substance, persons are required only to submit test data in their possession or control and to describe any other data known to or reasonably ascertainable by them (see 40 CFR 720.50). However, upon review of PMNs and SNUNs, the Agency has the authority to require appropriate testing. Descriptions of tests are provided for informational purposes. EPA strongly encourages persons, before performing any testing, to consult with the Agency pertaining to protocol selection. To access the OCSPP test guidelines referenced in this document electronically, please go to http://www.epa.gov/ocspp and select ‘‘Test 
Guidelines for Pesticides and Toxic Substances.’’ 
The recommended tests specified in 
Unit IV. may not be the only means of addressing the potential risks of the chemical substance. However, submitting a SNUN without any test data may increase the likelihood that EPA will take action under TSCA section 5(e), particularly if satisfactory test results have not been obtained from a prior PMN or SNUN submitter. EPA recommends that potential SNUN submitters contact EPA early enough so that they will be able to conduct the 
appropriate tests. 
SNUN submitters should be aware 
that EPA will be better able to evaluate SNUNs which provide detailed information on the following: 
•Human exposure and 
environmental release that may result from the significant new use of the chemical substances. 
•Potential benefits of the chemical 
substances. 
•Information on risks posed by the 
chemical substances compared to risks posed by potential substitutes. 
VIII. SNUN Submissions 
According to § 721.1(c), persons 
submitting a SNUN must comply with 
the same notification requirements and EPA regulatory procedures as persons submitting a PMN, including submission of test data on health and environmental effects as described in 40 
CFR 720.50. SNUNs must be submitted on EPA Form No. 7710–25, generated using e-PMN software, and submitted to the Agency in accordance with the procedures set forth in 40 CFR 720.40 and 721.25. E–PMN software is available electronically at https://www.epa.gov/reviewing-new-chemicals- under-toxic-substances-control-act-tsca/how-submit-e-pmn. 
IX. Economic Analysis 
EPA has evaluated the potential costs 
of establishing SNUN requirements for 
potential manufacturers and processors of the chemical substances subject to this proposed rule, during the development of the direct final rule. EPA’s complete economic analysis is available in the docket under docket ID number EPA–HQ–OPPT–2015–0388. 
X. Statutory and Executive Order 
Reviews 
A. Executive Order 12866 
This proposed rule would establish 
SNURs for three chemical substances 
that were the subject of PMNs. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ‘‘Regulatory Planning and Review’’ (58 FR 51735, October 4, 1993). 
B. Paperwork Reduction Act (PRA) 
According to PRA (44 U.S.C. 3501 et 
seq.), an agency may not conduct or 
sponsor, and a person is not required to respond to a collection of information that requires OMB approval under PRA, unless it has been approved by OMB and displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in title 40 
VerDate Sep<11>2014 14:59 Apr 12, 2016 Jkt 238001 PO 00000 Frm 00076 Fmt 4702 Sfmt 4702 E:\FR\FM\13APP1.SGM 13APP1jstallworth on DSK7TPTVN1PROD with PROPOSALS21834 Federal Register / Vol. 81, No. 71 / Wednesday, April 13, 2016 / Proposed Rules 
of the CFR, after appearing in the 
Federal Register, are listed in 40 CFR part 9, and included on the related collection instrument or form, if applicable. 
The information collection 
requirements related to this proposed rule have already been approved by OMB pursuant to PRA under OMB control number 2070–0012 (EPA ICR No. 574). This proposed rule would not impose any burden requiring additional OMB approval. If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average between 30 and 170 hours per response. This burden estimate includes the time needed to review instructions, search existing data sources, gather and maintain the data needed, and complete, review, and submit the required SNUN. 
Send any comments about the 
accuracy of the burden estimate, and any suggested methods for minimizing respondent burden, including through the use of automated collection techniques, to the Director, Collection Strategies Division, Office of Environmental Information (2822T), Environmental Protection Agency, 1200 Pennsylvania Ave. NW., Washington, DC 20460–0001. Please remember to include the OMB control number in any correspondence, but do not submit any completed forms to this address. 
C. Regulatory Flexibility Act (RFA) 
On February 18, 2012, EPA certified 
pursuant to RFA section 605(b) (5 U.S.C. 
601 et seq.), that promulgation of a 
SNUR does not have a significant economic impact on a substantial number of small entities where the following are true: 
1. A significant number of SNUNs 
would not be submitted by small entities in response to the SNUR. 
2. The SNUR submitted by any small 
entity would not cost significantly more than $8,300. 
A copy of that certification is 
available in the docket for this proposed rule. 
This proposed rule is within the 
scope of the February 18, 2012 certification. Based on the Economic Analysis discussed in Unit IX. And EPA’s experience promulgating SNURs (discussed in the certification), EPA believes that the following are true: 
•A significant number of SNUNs 
would not be submitted by small entities in response to the SNUR. 
•Submission of the SNUN would not 
cost any small entity significantly more than $8,300. 
Therefore, the promulgation of the 
SNUR would not have a significant economic impact on a substantial number of small entities. 
D. Unfunded Mandates Reform Act 
(UMRA) 
Based on EPA’s experience with 
proposing and finalizing SNURs, State, local, and Tribal governments have not been impacted by these rulemakings, and EPA does not have any reasons to believe that any State, local, or Tribal government would be impacted by this proposed rule. As such, EPA has determined that this proposed rule would not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments subject to the requirements of UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.). 
E. Executive Order 13132 
This proposed rule would not have a 
substantial direct effect on States, on the 
relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled ‘‘Federalism’’ (64 FR 43255, August 10, 1999). 
F. Executive Order 13175 
This proposed rule would not have 
Tribal implications because it is not 
expected to have substantial direct effects on Indian Tribes. This proposed rule would not significantly nor uniquely affect the communities of Indian Tribal governments, nor would it involve or impose any requirements that affect Indian Tribes. Accordingly, the requirements of Executive Order 13175, entitled ‘‘Consultation and Coordination with Indian Tribal Governments’’ (65 FR 67249, November 9, 2000), do not apply to this proposed rule. 
G. Executive Order 13045 
This proposed rule is not subject to 
Executive Order 13045, entitled 
‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997), because this is not an economically significant regulatory action as defined by Executive Order 12866, and this proposed rule does not address environmental health or safety risks disproportionately affecting children. 
H. Executive Order 13211 
This proposed rule is not subject to 
Executive Order 13211, entitled 
‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001), because this proposed rule is not expected to affect energy supply, distribution, or use and because this proposed rule is not a significant regulatory action under Executive Order 12866. 
I. National Technology Transfer and 
Advancement Act (NTTAA) 
In addition, since this proposed rule 
would not involve any technical standards, NTTAA section 12(d) (15 U.S.C. 272 note), would not apply to this proposed rule. 
J. Executive Order 12898 
This proposed rule does not entail 
special considerations of environmental 
justice related issues as delineated by Executive Order 12898, entitled ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations’’ (59 FR 7629, February 16, 1994).
