Appendix A. Definitions, Abbreviations, and Acronyms (for the purposes of this permit). 

A.1. DEFINITIONS

Action Area – all areas to be affected directly or indirectly by the federal action and not merely 

the immediate area involved in the action. See 50 CFR 402. For the purposes of this permit and 

for application of Endangered Species Act requirements, the following areas are included in the 

definition of action area:

• The areas where stormwater discharges originate and flow from the industrial facility to 

the point of discharge into receiving waters. (Example: Where stormwater flows into a 

ditch, swale, or gully that leads to receiving waters and where listed species (such as 

listed amphibians) are found in the ditch, swale, or gully.)

• The areas where stormwater from industrial activities discharge into receiving waters and 

the areas in the immediate vicinity of the point of discharge. (Example: Where 

stormwater from industrial activities discharges into a stream segment that is known to 

harbor listed aquatic species.)

• The areas where stormwater controls will be constructed and operated, including any 

areas where stormwater flows to and from the stormwater controls. (Example: Where a 

stormwater retention pond would be built.)

• The areas upstream and/or downstream from the stormwater discharge into a stream 

segment that may be affected by these discharges. (Example: Where sediment 

discharged to a receiving stream settles downstream and impacts a breeding area of a 

listed aquatic species.)

Antidegradation Policy or Antidegradation Requirements - the water quality standards regulation 

that requires States and Tribes to establish a three-tiered antidegradation program:

1. Tier 1 maintains and protects existing uses and water quality conditions necessary to 

support such uses. An existing use can be established by demonstrating that fishing, 

swimming, or other uses have actually occurred since November 28, 1975, or that the 

water quality is suitable to allow such uses to occur. Where an existing use is established, 

it must be protected even if it is not listed in the water quality standards as a designated 

use. Tier 1 requirements are applicable to all surface waters.

2. Tier 2 maintains and protects "high quality" waters -- water bodies where existing 

conditions are better than necessary to support CWA § 101(a)(2) "fishable/swimmable" 

uses. Water quality can be lowered in such waters. However, State and Tribal Tier 2 

programs identify procedures that must be followed and questions that must be 

answered before a reduction in water quality can be allowed. In no case may water 

quality be lowered to a level which would interfere with existing or designated uses.

3. Tier 3 maintains and protects water quality in outstanding national resource waters 

(ONRWs). Except for certain temporary changes, water quality cannot be lowered in 

such waters. ONRWs generally include the highest quality waters of the United States. 

However, the ONRW classification also offers special protection for waters of exceptional 

ecological significance, i.e., those which are important, unique, or sensitive ecologically. 

Decisions regarding which water bodies qualify to be ONRWs are made by States and 

authorized Indian Tribes.

exceptional recreational or ecological significance.

Total Maximum Daily Loads (TMDLs) – The sum of the individual wasteload allocations (WLAs) for 

point sources and load allocations (LAs) for nonpoint sources and natural background. If 

receiving water has only one point source discharger, the TMDL is the sum of that point source 

WLA plus the LAs for any nonpoint sources of pollution and natural background sources, 

tributaries, or adjacent segments. TMDLs can be expressed in terms of either mass per time, 

toxicity, or other appropriate measure. (See section 303(d) of the Clean Water Act and 40 CFR

A. You must comply with effluent standards or prohibitions established under section 307(a) 

of the Clean Water Act for toxic pollutants within the time provided in the regulations 

that establish these standards, even if the permit has not yet been modified to 

incorporate the requirement.

B. Penalties for Violations of Permit Conditions: The Director will adjust the civil and 

administrative penalties listed below in accordance with the Civil Monetary Penalty 

Inflation Adjustment Rule (61 FR 252, December 31, 1996, pp. 69359-69366, as corrected in 

62 FR 54, March 20, 1997, pp.13514-13517) as mandated by the Debt Collection 

Improvement Act of 1996 for inflation on a periodic basis. This rule allows EPA’s penalties 

to keep pace with inflation. The Agency is required to review its penalties at least once 

every 4 years thereafter and to adjust them as necessary for inflation according to a 

specified formula. The civil and administrative penalties following were adjusted for 

inflation starting in 1996.

1. Criminal Penalties.

1.1 Negligent Violations. The CWA provides that any person who negligently 

violates permit conditions implementing Sections 301, 302, 306, 307, 308, 318, 

or 405 of the Act is subject to criminal penalties of not less than $2,500 nor 

more than $25,000 per day of violation, or imprisonment of not more than 

one year, or both. In the case of a second or subsequent conviction for a 

negligent violation, a person shall be subject to criminal penalties of not 

more than $50,000 per day of violation or by imprisonment of not more than 

two years, or both.

1.2. Knowing Violations. The CWA provides that any person who knowingly 

violates permit conditions implementing Sections 301, 302, 306, 307, 308, 318, 

or 405 of the Act is subject to a fine of not less than $5,000 nor more than 

$50,000 per day of violation, or by imprisonment for not more than 3 years, 

or both. In the case of a second or subsequent conviction for a knowing 

violation, a person shall be subject to criminal penalties of not more than 

$100,000 per day of violation, or imprisonment of not more than 6 years, or 

both.

1.3. Knowing Endangerment. The CWA provides that any person who knowingly 

violates permit conditions implementing Sections 301, 302, 306, 307, 308, 318, 

or 405 of the Act and who knows at that time that he or she is placing 

another person in imminent danger of death or serious bodily injury shall 

upon conviction be subject to a fine of not more than $250,000 or by 

imprisonment of not more than 15 years, or both. In the case of a second or 

Page B-2 
Proposed 2013 MSGP

subsequent conviction for a knowing endangerment violation, a person 

shall be subject to a fine of not more than $500,000 or by imprisonment of 

not more than 30 years, or both. An organization, as defined in section 

309(c)(3)(B)(iii) of the Act, shall, upon conviction of violating the imminent 

danger provision be subject to a fine of not more than $1,000,000 and can 

fined up to $2,000,000 for second or subsequent convictions.

1.4. False Statement. The CWA provides that any person who falsifies, tampers 

with, or knowingly renders inaccurate any monitoring device or method 

required to be maintained under this permit shall, upon conviction, be 

punished by a fine of not more than $10,000, or by imprisonment for not 

more than 2 years, or both. If a conviction of a person is for a violation 

committed after a first conviction of such person under this paragraph, 

punishment is a fine of not more than $20,000 per day of violation, or by 

imprisonment of not more than 4 years, or both. The Act further provides 

that any person who knowingly makes any false statement, representation, 

or certification in any record or other document submitted or required to be 

maintained under this permit, including monitoring reports or reports of 

compliance or non-compliance shall, upon conviction, be punished by a 

fine of not more than $10,000 per violation, or by imprisonment for not more 

than 6 months per violation, or by both.

2. Civil Penalties. The CWA provides that any person who violates a permit 

condition implementing Sections 301, 302, 306, 307, 308, 318, or 405 of the Act is 

subject to a civil penalty not to exceed the maximum amounts authorized by 

Section 309(d) of the Act and the Federal Civil Penalties Inflation Adjustment 

Act (28 U.S.C. § 2461 note) as amended by the Debt Collection Improvement 

Act (31 U.S.C. § 3701 note) (currently $37,500 per day for each violation).

3. Administrative Penalties. The CWA provides that any person who violates a 

permit condition implementing Sections 301, 302, 306, 307, 308, 318, or 405 of 

the Act is subject to an administrative penalty, as follows

3.1. Class I Penalty. Not to exceed the maximum amounts authorized by Section 

309(g)(2)(A) of the Act and the Federal Civil Penalties Inflation Adjustment

with the maximum amount of any Class I penalty assessed not to exceed 

$37,500). 

3.2. Class II Penalty. Not to exceed the maximum amounts authorized by 

Section 309(g)(2)(B) of the Act and the Federal Civil Penalties Inflation 

Adjustment Act (28 U.S.C. § 2461 note) as amended by the Debt Collection 

Improvement Act (31 U.S.C. § 3701 note) (currently $11,000 per day for each 

day during which the violation continues, with the maximum amount of any 

Class II penalty not to exceed $177,500).

B.2 Duty to Reapply.

renders inaccurate any monitoring device or method required to be maintained under 

this permit shall, upon conviction, be punished by a fine of not more than $10,000, or by 

imprisonment for not more than 2 years, or both. If a conviction of a person is for a 

violation committed after a first conviction of such person under this paragraph, 

punishment is a fine of not more than $20,000 per day of violation, or by imprisonment of 

not more than 4 years, or both.

B.11 Signatory Requirements.

A. All applications, including NOIs, must be signed as follows:

1. For a corporation: By a responsible corporate officer. For the purpose of this

subsection, a responsible corporate officer means: (i) a president, secretary, 

treasurer, or vice-president of the corporation in charge of a principal business 

function, or any other person who performs similar policy- or decision-making 

Page B-5 
Proposed 2013 MSGP

functions for the corporation, or (ii) the manager of one or more 

manufacturing, production, or operating facilities, provided, the manager is 

authorized to make management decisions which govern the operation of the 

regulated facility including having the explicit or implicit duty of making major 

capital investment recommendations, and initiating and directing other 

comprehensive measures to assure long term environmental compliance with 

environmental laws and regulations; the manager can ensure that the 

necessary systems are established or actions taken to gather complete and 

accurate information for permit application requirements; and where authority 

to sign documents has been assigned or delegated to the manager in 

accordance with corporate procedures.

2. For a partnership or sole proprietorship: By a general partner or the proprietor, 

respectively; or

3. For a municipality, state, federal, or other public agency: By either a principal 

executive officer or ranking elected official. For purposes of this subsection, a 

principal executive officer of a federal agency includes (i) the chief executive 

officer of the agency, or (ii) a senior executive officer having responsibility for 

the overall operations of a principal geographic unit of the agency (e.g., 

Regional Administrator of EPA).

B. Your SWPPP, including changes to your SWPPP to document any corrective actions 

taken as required by Part 3.1, and all reports submitted to EPA, must be signed by a 

person described in Appendix B, Subsection 11.A above or by a duly authorized 

representative of that person. A person is a duly authorized representative only if:

1. The authorization is made in writing by a person described in Appendix B, 

Subsection 11.A;

2. The authorization specifies either an individual or a position having responsibility 

for the overall operation of the regulated facility or activity such as the position 

of plant manager, operator of a well or a well field, superintendent, position of 

equivalent responsibility, or an individual or position having overall responsibility 

for environmental matters for the company. (A duly authorized representative 

may thus be either a named individual or any individual occupying a named 

position); and

3. The signed and dated written authorization is included in the SWPPP. A copy 

must be submitted to EPA, if requested.

C. All other changes to your SWPPP, and other compliance documentation required under 

Part 5.4, must be signed and dated by the person preparing the change or 

documentation.

D. Changes to Authorization. If an authorization under Part 1.3.1.3 is no longer accurate 

because the industrial facility has been purchased by a different entity, a new NOI 

satisfying the requirements of Part 1.3 must be submitted to EPA. See Table 1-2 in Part 

1.3.1.1 of the permit. However, if the only change that is occurring is a change in 

contact information or a change in the facility’s address, the operator need only make a 

modification to the existing NOI submitted for authorization.

Page B-6 
Proposed 2013 MSGP

E. Any person signing documents in accordance with Appendix B, Subsections 11.A or 11.B 

above must 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 gathered and evaluated the 

information contained therein. Based on my inquiry of the person or persons who 

manage the system, or those persons directly responsible for gathering the 

information, the information contained 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.”

F. For persons signing documents electronically, in addition to meeting other applicable 

requirements in Appenidx I, Subsection B.11, such signatures must meet the same 

signature, authentication, and identity-proofing standards set forth at 40 CFR § 3.2000(b) 

for electronic reports (including robust second-factor authentication).

G. The CWA provides that any person who knowingly makes any false statement, 

representation, or certification in any record or other document submitted or required to 

be maintained under this permit, including monitoring reports or reports of compliance or 

non-compliance shall, upon conviction, be punished by a fine of not more than $10,000 

per violation, or by imprisonment for not more than 6 months per violation, or by both.

B.12 Reporting Requirements.

A. Planned changes. You must give notice to EPA as soon as possible of any planned 

physical alterations or additions to the permitted facility. Notice is required only when:

1. The alteration or addition to a permitted facility may meet one of the criteria for 

determining whether a facility is a new source in 40 CFR 122.29(b); or

2. The alteration or addition could significantly change the nature or increase the 

quantity of pollutants discharged. This notification applies to pollutants which 

are subject neither to effluent limitations in the permit, nor to notification 

requirements under 40 CFR 122.42(a)(1). 

B. Anticipated noncompliance. You must give advance notice to EPA of any planned 

changes in the permitted facility or activity which may result in noncompliance with 

permit requirements.

C. Transfers. This permit is not transferable to any person except after notice to EPA. Where a 

facility wants to change the name of the permittee, the original permittee (the first 

owner or operators) must submit a Notice of Termination pursuant to Part 1.4. The new 

owner or operator must submit a Notice of Intent in accordance with Part 1.3.1 and 

Table 1-2. See also requirements in Appendix B, Subsections 11.B and 11.D.

D. Monitoring reports. Monitoring results must be reported at the intervals specified 

elsewhere in this permit.

Page B-7 
Proposed 2013 MSGP

1. Pursuant to Part 7.1, all monitoring data collected pursuant to Part 6.2 and 6.3 

must be submitted to EPA using EPA’s online eNOI system 

(www.epa.gov/npdes/eNOI). 

2. If you monitor any pollutant more frequently than required by the permit using 

test procedures approved under 40 CFR Part 136 or as specified in the permit, 

the results of this monitoring must be included in the calculation and reporting 

of the data submitted in the MDMR.

3. Calculations for all limitations which require averaging of measurements must 

use an arithmetic mean. For averaging purposes, use a value of zero for any 

individual sample parameter, which is determined to be less than the method 

detection limit. For sample values that fall between the method detection level 

and the quantitation limit (i.e., a confirmed detection but below the level that 

can be reliably quantified), use a value halfway between zero and the 

quantitation limit.

E. Compliance schedules. Reports of compliance or noncompliance with, or any progress 

reports on, interim and final requirements contained in any compliance schedule of this 

permit must be submitted no later than 14 days following each schedule date.

F. Twenty-four hour reporting. 

1. You must report any noncompliance which may endanger health or the 

environment. Any information must be provided orally within 24 hours from the 

time you become aware of the circumstances. A written submission must also 

be provided within five days of the time you become aware of the 

circumstances. The written submission must contain a description of the 

noncompliance and its cause; the period of noncompliance, including exact 

dates and times, and if the noncompliance has not been corrected, the 

anticipated time it is expected to continue; and steps taken or planned to 

reduce, eliminate, and prevent reoccurrence of the noncompliance.

2. The following shall be included as information which must be reported within 24 

hours under this paragraph.

a. Any unanticipated bypass which exceeds any effluent limitation in the 

permit. (See 40 CFR 122.41(m)(3)(ii))

b. Any upset which exceeds any effluent limitation in the permit

c. Violation of a maximum daily discharge limit for any numeric effluent 

limitation. (See 40 CFR 122.44(g).) 

3. EPA may waive the written report on a case-by-case basis for reports under 

Appendix B, Subsection 12.F.2 if the oral report has been received within 24 

hours.

G. Other noncompliance. You must report all instances of noncompliance not reported 

under Appendix B, Subsections 12.D, 12.E, and 12.F, at the time monitoring reports are 

submitted. The reports must contain the information listed in Appendix B, Subsection 12.F.

Page B-8 
Proposed 2013 MSGP

H. Other information. Where you become aware that you failed to submit any relevant 

facts in a permit application, or submitted incorrect information in a permit application 

or in any report to the Permitting Authority, you must promptly submit such facts or 

information.

B.13 Bypass.

A. Definitions.

1. Bypass means the intentional diversion of waste streams from any portion of a 

treatment facility See 40 CFR 122.41(m)(1)(i). 

2. Severe property damage means substantial physical damage to property, 

damage to the treatment facilities which causes them to become inoperable, 

or substantial and permanent loss of natural resources which can reasonably 

be expected to occur in the absence of a bypass. Severe property damage 

does not mean economic loss caused by delays in production. See 40 CFR 

122.41(m)(1)(ii). 

B. Bypass not exceeding limitations. You may allow any bypass to occur which does not 

cause effluent limitations to be exceeded, but only if it also is for essential maintenance 

to assure efficient operation. These bypasses are not subject to the provisions of 

Appendix B, Subsections 13.C and 13.D. See 40 CFR 122.41(m)(2). 

C. Notice.

1. Anticipated bypass. If you know in advance of the need for a bypass, you must 

submit prior notice, if possible at least ten days before the date of the bypass. 

See 40 CFR 122.41(m)(3)(i). 

2. Unanticipated bypass. You must submit notice of an unanticipated bypass as 

required in Appendix B, Subsection 12.F (24-hour notice). See 40 CFR 

122.41(m)(3)(ii). 

D. Prohibition of bypass. See 40 CFR 122.41(m)(4). 

1. Bypass is prohibited, and EPA may take enforcement action against you for 

bypass, unless:

a. Bypass was unavoidable to prevent loss of life, personal injury, or severe 

property damage;

b. There were no feasible alternatives to the bypass, such as the use of 

auxiliary treatment facilities, retention of untreated wastes, or maintenance 

during normal periods of equipment downtime. This condition is not satisfied 

if adequate back-up equipment should have been installed in the exercise 

of reasonable engineering judgment to prevent a bypass which occurred 

during normal periods of equipment downtime or preventive maintenance; 

and

c. You submitted notices as required under Appendix B, Subsection 13.C.

Page B-9 
Proposed 2013 MSGP

2. EPA may approve an anticipated bypass, after considering its adverse effects, 

if EPA determines that it will meet the three conditions listed above in Appendix 

B, Subsection 13.D.1. 

B.14 Upset.

A. Definition. Upset means an exceptional incident in which there is unintentional and 

temporary noncompliance with technology based permit effluent limitations because of 

factors beyond your reasonable control. An upset does not include noncompliance to 

the extent caused by operational error, improperly designed treatment facilities, 

inadequate treatment facilities, lack of preventive maintenance, or careless or improper 

operation. See 40 CFR 122.41(n)(1).

B. Effect of an upset. An upset constitutes an affirmative defense to an action brought for 

noncompliance with such technology based permit effluent limitations if the 

requirements of Appendix B, Subsection 14.C are met. No determination made during 

administrative review of claims that noncompliance was caused by upset, and before 

an action for noncompliance, is final administrative action subject to judicial review. See 

40 CFR 122.41(n)(2). 

C. Conditions necessary for a demonstration of upset. See 40 CFR 122.41(n)(3). A permittee 

who wishes to establish the affirmative defense of upset must demonstrate, through 

properly signed, contemporaneous operating logs, or other relevant evidence that:

1. An upset occurred and that you can identify the cause(s) of the upset;

2. The permitted facility was at the time being properly operated; and

3. You submitted notice of the upset as required in Appendix B, Subsection 

12.F.2.b (24 hour notice). 

4. You complied with any remedial measures required under Appendix B, 

Subsection 4.

D. Burden of proof. In any enforcement proceeding, you, as the one seeking to establish 

the occurrence of an upset, have the burden of proof. See 40 CFR 122.41(n)(4). 

B.15 Retention of Records.

Copies of the SWPPP and all documentation required by this permit, including records of all data 

used to complete the NOI to be covered by this permit, must be retained for at least three years 

from the date that permit coverage expires or is terminated. This period may be extended by 

request of EPA at any time.

B.16 Reopener Clause.

A. Procedures for modification or revocation. Permit modification or revocation will be 

conducted according to 40 CFR §122.62, §122.63, §122.64 and §124.5. 

B. Water quality protection. If there is evidence indicating that the stormwater discharges 

authorized by this permit cause, have the reasonable potential to cause or contribute to 

an excursion above any applicable water quality standard, you may be required to 

Page B-10
Proposed 2013 MSGP

obtain an individual permit in accordance with Part 1.3.3 of this permit, or the permit may 

be modified to include different limitations and/or requirements.

C. Timing of permit modification. EPA may elect to modify the permit prior to its expiration 

(rather than waiting for the new permit cycle) to comply with any new statutory or 

regulatory requirements, such as for effluent limitation guidelines that may be 

promulgated in the course of the current permit cycle.

B.17 Severability

Invalidation of a portion of this permit does not necessarily render the whole permit invalid. EPA’s 

intent is that the permit is to remain in effect to the extent possible; in the event that any part of 

this permit is invalidated, EPA will advise the regulated community as to the effect of such 

invalidation.

Proposed 2013 MSGP

Appendix E. Procedures Relating to Endangered Species Protection

E.1 Assessing the Effects of Your Discharges and Discharge-Related Activities

You must follow the procedures in this appendix to determine which of the eligibility 

criterion in Part 1.1.4.5 (see Part E.2), if any, you qualify under, by assessing the potential effects 

of applicable stormwater discharges, discharge-related activities, and allowable nonstormwater discharges on listed threatened and endangered species and their designated 

critical habitat. In accordance with Part 5.2.6.1 of this permit, you must keep the E.4 worksheet in 

this appendix and additional documentation with your SWPPP to support your certification of 

eligibility. You must complete your eligibility determination prior to submitting your NOI for 

coverage under the MSGP, and must provide all information required on the NOI form that 

supports the ESA eligibility criterion you qualify under. (Note that if you have determined your 

eligibility under Criterion C, you must submit your completed Criterion C worksheet to EPA and 

the Services a minimum of 30 days prior to submitting your NOI for permit coverage). 

When evaluating the potential effects of your activities, you must consider effects to 

listed species or critical habitats within the “action area.” Action area is defined in Appendix A 

as all areas to be affected directly or indirectly by the federal action and not merely the 

immediate area involved in the action. This includes areas beyond the footprint of the facility 

that are likely to be affected by stormwater discharges, discharge-related activities, and 

allowable non-stormwater discharges. For example, discharges of pollutants into downstream 

areas can increase the “action area” beyond the footprint of the facility. “Facility” is defined in 

Appendix A.

E.2 Eligibility Criterion

 As required by Part 1.1.4.5, you must meet one or more of the following five criteria (A - E) 

to be eligible for coverage under the permit for your stormwater discharges, discharge-related 

activities, and allowable non-stormwater discharges: 

Criterion A. No federally-listed threatened or endangered species or their designated critical 

habitat(s) are likely to occur in the “action area” as defined in Appendix A. To 

certify your eligibility under this criterion, you must use the E.4 Criterion Selection 

worksheet. You must also provide a description of the basis for the criterion you 

selected on your NOI form and provide documentation supporting your eligibility 

determination in your SWPPP.

Criterion B. The industrial activity’s discharges and discharge-related activities were already 

addressed in another operator’s valid certification of eligibility for your action 

area under this permit and there is no reason to believe that federally-listed 

species or federally-designated critical habitat not considered in the prior 

certification may be present or located in the “action area” (e.g., due to a new 

species listing or critical habitat designation). To certify your eligibility under this 

criterion, there must be no lapse of NPDES permit coverage in the other 

operator’s certification. You must also comply with any terms and conditions 

imposed under the other operator's valid certification of eligibility to ensure that 

your discharges and discharge-related activities are protective of listed species 

and/or critical habitat. To certify your eligibility under this criterion, you must use 

the E.4 Criterion Selection worksheet. You must include in your NOI the NPDES ID 

from the other operator’s notification of authorization under this permit, and a 

description of the basis for the criterion selected on your NOI form, including the 

eligibility criterion selected by the other operator’s certification. You must also 

provide any documentation in your SWPPP that supports the other operator’s 

eligibility determination, as well as any terms and conditions imposed under the 

eligibility requirements that applied under the prior certification. 

Page E-2 
Proposed 2013 MSGP

Criterion C. Federally-listed threatened or endangered species or their designated critical 

habitat(s) are likely to occur in or near your facility’s “action area,” and your 

industrial activity’s discharges and discharge-related activities are not likely to 

adversely affect listed threatened or endangered species or critical habitat. To 

certify your eligibility under this criterion, you must use the E.4 Criterion Selection 

worksheet. At least 30 days prior to filing your NOI for permit coverage, you must 

submit to EPA and the Services your completed Criterion C worksheet. After 

evaluation of your worksheet, EPA may require additional controls that you must 

implement to avoid or eliminate adverse effects on listed species and critical 

habitat from discharges and discharge-related activities. You may submit your 

NOI for permit coverage 30 days after submitting your completed Criterion C

worksheet. You must provide a description of the basis for the criterion you 

selected on your NOI form and provide documentation supporting your eligibility 

determination in your SWPPP.

Criterion D. Consultation between a Federal Agency and the U.S. Fish and Wildlife Service 

and/or the National Marine Fisheries Service under section 7 of the ESA has been 

concluded. Consultations can be either formal or informal, and would have 

occurred only as a result of a separate federal action (e.g., during application for 

an individual wastewater discharge permit or the issuance of a wetlands dredge 

and fill permit), and consultation must have addressed the effects of the industrial 

activity’s discharges and discharge-related activities on all federally-listed 

threatened or endangered species and all federally-designated critical habitat. 

The result of this consultation must be either:

i. A biological opinion that concludes that the action in question (taking into 

account the effects of your facility’s discharges and discharge-related 

activities) is not likely to jeopardize the continued existence of listed species, 

nor the destruction or adverse modification of critical habitat; or

ii. Written concurrence from the applicable Service(s) with a finding that the 

facility’s discharges and discharge-related activities are not likely to adversely 

affect federally-listed species or federally-designated critical habitat. 

To certify your eligibility under this criterion, you must use the E.4 Criterion 

Selection worksheet. You must verify that the consultation remains valid, in 

accordance with 50 CFR §402.16. If reinitiation of consultation is required, in order 

to be eligible under this Criterion you must conclude the reinitiated consultation 

and the result of the consultation must be consistent with (i) or (ii) above. 

If eligible, you must also provide supporting documentation for your 

determination in your NOI and SWPPP, including the Biological Opinion (or PCTS 

tracking number) or concurrence letter. 

Criterion E. Your industrial activities are authorized through the issuance of a permit under 

section 10 of the ESA, and this authorization addresses the effects of the facility’s 

discharges and discharge-related activities on federally-listed species and 

federally-designated critical habitat. To certify your eligibility under this criterion, 

you must use the E.4 Criterion Selection worksheet. You must also provide 

supporting documentation for your determination in your NOI and SWPPP, 

including a copy of the permit from the Services.

E.3 Eligibility Compliance

You must comply with any applicable terms, conditions, or other requirements developed in the 

process of meeting the eligibility criteria in this section for the duration of your coverage under 

Page E-3 
Proposed 2013 MSGP

the MSGP in order to maintain your eligibility for coverage under the permit. Documentation of 

these requirements must be kept as part of your SWPPP (see Part 5.2.6.1). 

E.4 Criterion Selection Worksheet

Instructions:

You must follow the step-by-step instructions in this worksheet in order to determine your eligibility 

under the Part 1.1.4.5 criteria, and must enter in the appropriate information supporting the 

criterion you have selected. If you prefer to use a Biological Evaluation (or its equivalent) in making 

a determination of your eligibility, you should ensure all of the information requested below for the 

criterion you are selecting is fully addressed in such a document. You must attach this completed 

document or Biological Evaluation (or equivalent) to your SWPPP to support your Part 1.1.4.5 

eligibility determination. 

You may need the following information in order to determine your eligibility: 

1) Your facility’s draft Stormwater Pollution Prevention Plan (SWPPP), including information on 

receiving waters.

2) Any additional site-specific information related to your facility’s discharges and dischargerelated activities. 

3) The list(s) of endangered and threatened species and any designated critical habitat in 

your action area, as acquired from the Fish and Wildlife Service and/or the National Marine 

Fisheries Services. Directions on how to acquire species lists is described in a subsequent 

section below.

Note that much of this information you will need to have in preparing your NOI for permit 

coverage, and is also information that you must develop as part of your SWPPP. Any information 

that is already required and completed in your SWPPP you may copy and paste into this 

worksheet. (You may also decide to make minor changes or additions to your SWPPP while filling 

out the worksheet for clarification purposes or to address any concerns that are identified below.)

STEP 1: DETERMINE IF THE ELIGIBILITY REQUIREMENTS OF CRITERION B, D, OR E CAN BE MET.

You should first determine whether you are eligible under criterion B (because another operator has 

accounted for your action area in their valid certification of eligibility, criterion D (because of a 

previously completed ESA section 7 consultation), or criterion E (because of a previously issued ESA 

Section 10 permit). If your facility is likely to be eligible under criterion B, D or E, you may skip ahead 

to the applicable criterion’s requirements to determine if you are eligible. If after completing the 

relevant section you find that your facility does not in fact meet criteria B, D, or E (e.g., due to 

difference in action area described, lack of analysis of appropriate effects, new listings or 

designation of critical habitat), proceed to Step 2 below.

If your facility is not likely to be eligible under criterion B, D or E, you may proceed directly to Step 2. 

Criterion B Eligibility Requirements

If your industrial activities were already addressed in another operator’s valid certification of 

eligibility under the current 2013 MSGP, you may be eligible for coverage under criterion B. In order 

to be eligible for coverage under criterion B, you must confirm that all the following are true: 

You have confirmed that the other operator’s certification of eligibility accounted for your action 

area and that the eligibility determination was valid. 

There has been no lapse of NPDES permit coverage in the other operator’s certification.

Page E-4 
Proposed 2013 MSGP

 Your facility will comply with all terms and conditions imposed under the other operator’s valid 

certification of eligibility. List any terms and conditions here (or enter “N/A” if none exist):

- If all of the above are true, you may select criterion B on your NOI. You must include in your NOI 

the NPDES ID from the other operator’s notification of authorization under this permit, and a 

description of the basis for the criterion selected on your NOI form, including the eligibility 

criterion selected by the other operator’s certification. You must include this completed 

Appendix E.4 worksheet in your SWPPP.

- If any of the above are not true, you may not select criterion B and must proceed to Step 2. For 

example, if there are any listed species in your action area that were not addressed in the other 

operator’s certification, you are not eligible under criterion B. 

Criterion D Eligibility Requirements

If consultation under section 7 of the ESA has been concluded, you may be eligible for coverage 

under criterion D. In order to be eligible or coverage under criterion D, you must confirm that all the 

following are true:

 A consultation between a Federal Agency and the U.S. Fish and Wildlife Service and/or the 

National Marine Fisheries Service under section 7 of the ESA has been concluded. Consultations can 

be either formal or informal, and would have occurred only as a result of a separate federal action 

(e.g., during application for an individual wastewater discharge permit or the issuance of a 

wetlands dredge and fill permit), and consultation must have addressed the effects of the industrial 

activity’s discharges and discharge-related activities on all federally-listed threatened or 

endangered species and all federally-designated critical habitat in your action area. The result of 

this consultation must be either:

i. A biological opinion that concludes that the action in question (taking into account the 

effects of your facility’s discharges and discharge-related activities) is not likely to jeopardize 

the continued existence of listed species, nor the destruction or adverse modification of 

critical habitat. The biological opinion must have included the effects of your facility’s 

dischargesa and discharge-related activities on all the listed species and designated critical 

habitat in your action area; or

ii. Written concurrence (e.g., letter of concurrence) from the applicable Service(s) with a 

finding that concludes that your facility’s discharges and discharge-related activities are not 

likely to adversely affect listed species or designated critical habitat. The concurrence letter 

must have included the effects of your facility’s discharges and discharge-related activities 

on all the listed species and designated critical habitat on your species list(s) acquired from 

the Service(s) as part of this worksheet. 

a Effects of discharge includes, but is not limited to, the analysis of the hydrological, chemical, and biological effects 

of the discharge on listed species, their prey, and their habitat, as well as critical habitat, where designated. For 

example, the effects analysis would have evaluated whether the various pollutants in the discharge (e.g., TSS, 

metals) would adversely affect listed species through exposure to the pollutants, or to their prey or habitat. Effects 

that look only at short-term effects unrelated to the stormwater discharge effects to listed species are not sufficient 

for these purposes.

Proposed 2013 MSGP

 The consultation remains valid, in accordance with 50 CFR §402.16; or, if reinitiation of 

consultation is required (e.g., due to a new species listing or critical habitat designation; new 

information), you have concluded the reinitiated consultation and the result of the consultation is 

consistent with the statements above. Attach a copy of any reinitiation documentation from the 

Services or other consulting federal agency. 

- If all of the above are true, you may select criterion D on your NOI. You must also provide a 

description of the basis for the criterion selected on your NOI form and you must include this 

completed Appendix E.4 worksheet in your SWPPP. In both your SWPPP and NOI you must also 

provide the Biological Opinion (or PCTS tracking number) or concurrence letter and any other 

documentation supporting your eligibility determination. 

- If any of the above are not true, you may not select criterion D and must proceed to Step 2. For 

example, if the biological opinion or written concurrence did not include the effects of the 

discharge or discharge-related activities as described above (e.g., the previous consultation 

covered some but not all of the species or critical habitat in your action area as shown on your 

species list), or if the consultation is no longer valid (e.g., due to new species listings), you are not 

eligible under criterion D. 

Criterion E Eligibility Requirements

If industrial activities are authorized through the issuance of a permit under section 10 of the ESA, 

and this authorization addresses the effects of the facility’s discharges and discharge-related 

activities on federally-listed species and federally-designated critical habitat, you may be eligible for 

coverage under criterion E. In order to be eligible or coverage under Criterion E, you must confirm 

that the following is true:

 A permit has been issued under section 10 of the ESA. The permit authorization specifically 

addresses the effects of the facility’s discharges and discharge-related activities (if applicable) on 

all federally listed species and designated critical habitat in your action area. 

- If the above is true, you may select criterion E on your NOI. You must also provide a description 

of the basis for the criterion selected on your NOI form must include this completed Appendix E.4 

worksheet in your SWPPP. In both your SWPPP and NOI you must provide a copy of the permit 

issued by the Services. 

- If the above is not true, you may not select criterion E and must proceed to Step 2. For example, 

If a permit has been issued under section 10 of the ESA, but the permit authorization does not 

address the effects of the facility’s discharges and/or discharge-related activities on all federally 

listed species and designated critical habitat on your species list, you are not eligible under 

criterion E, but you should attach a copy of the permit to the SWPPP for reference.

STEP TWO: DETERMINE THE EXTENT OF YOUR ACTION AREA

You must determine whether species listed as either threatened or endangered, or their critical 

habitat(s) (see definitions of these terms in Appendix A), are located in your facility’s action area 

(i.e., all areas to be affected directly or indirectly by the federal action and not merely the 

immediate area involved in the action, including areas beyond the footprint of the facility that are 

likely to be affected by stormwater discharges, discharge-related activities, and allowable nonstormwater discharges). Consider the following in determining the action area for your facility:

• Discharges of pollutants into downstream areas can expand the action area well beyond 

the footprint of your facility and the discharge point(s). Take into account the controls you 

will be implementing to minimize pollutants and the receiving waterbody characteristics 

(e.g., perennial, intermittent, ephemeral) in determining the extent of physical, chemical, 

and/or biotic effects of the discharges. All receiving waterbodies that could receive 

pollutants from your facility must be included in your action area. 

Page E-6 
Proposed 2013 MSGP

• Discharge-related activities must also be accounted for in determining your action area. 

Discharge-related activities are any activities that cause, contribute to, or result in 

stormwater and allowable non-stormwater point source discharges, and measures such as 

the siting, construction, and operation of stormwater controls to control, reduce, or prevent 

pollutants from being discharged. For example, any new or modified stormwater controls 

that will have noise or other similar effects, and any disturbances associated with vehicle 

access or construction of controls, are part of your action area.

If you have any questions about determining the extent of your action area, you may choose to 

contact EPA or the Services for assistance. 

You must describe the action area of your facility in Attachment 1 of this Appendix. 

You must proceed to Step 3 below.

STEP 3: DETERMINE IF LISTED THREATENED OR ENDANGERED SPECIES AND CRITICAL HABITAT ARE 

PRESENT IN YOUR ACTION AREA.

You must determine whether species listed as either threatened or endangered under the 

Endangered Species Act (ESA), or their designated critical habitat(s)b, are located in your facility’s 

action area. Federally-listed species and designated critical habitat are under the purview of the 

National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (FWS) (together, 

“Services”), and in many cases, species and critical habitat lists will need to be acquired from both 

Services. 

• For NMFS species and critical habitat information, use the following webpages, which 

provide up-to-date information on listed species 

(http://www.nmfs.noaa.gov/pr/species/esa/) and critical habitat 

(http://www.nmfs.noaa.gov/pr/species/criticalhabitat.htm). To determine the field office 

that corresponds to your facility, go to http://www.nmfs.noaa.gov/ (under the left tab for 

“Regions”). 

• For FWS species information, use the on-line mapping tool IPAC (the Information, Planning, 

and Consultation System) located at http://ecos.fws.gov/ipac/, and follow these steps:

o Select Initial Project Scoping. 

o Use the Map feature to define your project location. (Using the state/county list may 

result in more species being listed than you need to consider for your project.)

o Zoom into your location or choose the “Find a Place” search to locate your site. 

o Use the zoom feature to see the entire extent of your action area on the screen.

o Use the draw feature (represented by the pencil icon) to draw your action area as a 

polygon. 

 For the aquatic portion of your action area, trace the water body(ies) with the tool 

to characterize your action area. (A large/broad circle may include more species 

than would be present with better definition of your action area.)

 If your proposal wil include any upland activities (e.g., discharge-related activities), 

or if there is some aspect of your discharge that would potentially result in effects 

to terrestrial species, include the corresponding upland areas within your action 

area.

 When you are done, press Continue. 

o Select “Water Quality Modification” under the project type and continue.

b See definitions of these terms in Appendix A of the MSGP.

Page E-7 

 
Proposed 2013 MSGP

Note: For existing 

dischargers that have 

previously obtained 

coverage under Criterion 

A, you must verify whether 

listed species and/or 

critical habitat are 

expected to exist in your 

action area, as described 

above. Please note that if 

you now find that your 

action area overlaps with 

listed species or critical 

habitat, you must proceed 

to Step 4. 

o Follow the link to acquire an Official Species List, which should show both listed species as 

well as any designated critical habitat that is present in the action area polygon in the 

previous step. Note: If a link to an Official Species List is not available on the page, 

follow the web link of the office(s) indicated, or contact the office directly by mail or 

phone if a web link is not shown.

The principle authority for critical habitat designations and associated requirementsis found at 50 

CFR Parts 17 and 226. http://www.access.gpo.gov. 

Attach a copy of the species and critical habitat list(s) from the Service(s) to Attachment 2 of this 

appendix and use the list(s) to complete the rest of this worksheet. 

If after following the steps you have determined that there are no listed species and/or designated 

critical habitat in your action area, you may be eligible for coverage under criterion A. 

If you have determined that there are or may be listed species 

and/or designated critical habitat in your action area, you are not 

eligible under criterion A and must proceed to Step 4 below.

Criterion A Eligibility Requirements

In order to be eligible or coverage under criterion A, you must 

confirm that the following is true: 

 I have confirmed there to be no listed species and no critical 

habitat in my action area. 

- If the above is true, you may select criterion A on your NOI form. 

You must also provide a description of the basis for the criterion 

selected on your NOI form. You must include this completed 

Appendix E.4 worksheet in your SWPPP.

- If the above is not true, you may not select criterion A and must 

proceed to Step 4 to determine if you can become eligible 

under criterion C. 

STEP 4: Determine if Your Industrial Facility’s Discharges or Discharge-Related Activities Are 

Likely to Adversely Affect Listed Threatened or Endangered Species or Designated 

Critical Habitat and Any Measures that Must be Implemented to Avoid Adverse Effects

If in Step 3 you determined that listed species and/or designated critical habitat could exist in your 

action area, you must next assess whether your discharges and discharge-related activities are likely 

to adversely affect listed threatened or endangered species or designated critical habitat, and 

whether any additional controls are necessary to ensure no likely adverse affects. In order to make 

a determination of your facility’s likelihood of adverse affects, you must complete the attached 

criterion C worksheet and must submit this worksheet to EPA and the applicable Services office a 

minimum of 30 days prior to filing your NOI for permit coverage. After you submit your worksheet, 

you may be contacted by EPA with additional requirements that you must implement in order to 

ensure your eligibililty under criterion C. 

Page E-8 
Proposed 2013 MSGP

Criterion C Worksheet 

Instructions:

In order to be eligible for coverage under Criterion C, you must complete the following worksheet 

and must make a preliminary determination that your discharges and discharge-related activities 

are not likely to adversely affect listed threatened or endangered species or designated critical 

habitat. This determination may require the implementation of additional controls or modifications 

to your discharge-related activities. You must submit this worksheet to EPA and the Services a 

minimum of 30 days prior to filing your NOI for permit coverage. After you submit your worksheet, 

you may be contacted by EPA with additional requirements that you must implement in order to 

ensure your eligibility under criterion C.

If after completing this worksheet you cannot make a determination that your discharges and 

discharge-related activities are not likely to adversely affect listed threatened or endangered 

species or designated critical habitat, you must submit this completed worksheet to EPA and the 

Services, but you may not file your NOI for permit coverage. You must coordinate with EPA and the 

Services to determine if there are any additional controls you can implement in order to become 

eligible under criterion C.

Note: Much of the information needed for this from you can gather from your draft SWPPP and will 

be needed when you file your NOI.

SECTION II. ACTION AREA

Ensure that your action area is described in Attachment 1, as required in Step 2. 

SECTION III. LISTED SPECIES AND CRITICAL HABITAT LIST

Ensure that the listed species and critical habitat list is 

included in Attachment 2, as required in Step 3. 

Review your species list in Attachment 2, and choose 

one of the following three statements and follow the 

corresponding instructions: 

 The species list includes only terrestrial species 

and/or their designated critical habitat. No aquatic or 

aquatic-dependent species or their critical habitat are 

present in the action area. You must fill out Section IV 

of this worksheet and you are not required to fill out

area. You must fill out Section V of this worksheet and are not required to fill out Section IV. 

The species list includes both terrestrial and aquatic or aquatic-dependent species and/or their 

designated critical habitat. You must fill out both Section IV and V of this worksheet. 

SECTION IV. EVALUATION OF DISCHARGE-RELATED ACTIVITIES EFFECTS

Note: You are only required to fill out this section if your facility’s action area included terrestrial species 

and/or their designated critical habitat. If your action area only contains aquatic and/or aquaticdependent species and/or their designated critical habitat, you can skip directly to Section V.

Page E-10
Proposed 2013 MSGP

Most of the potential effects related to coverage under the MSGP are assumed to occur to aquatic 

and/or aquatic-dependent species. However, in some cases, potential effects to terrestrial species 

and/or their critical habitat should be considered as well from discharge-related activities that 

occur during coverage under the MSGP. Examples of potential effects that could occur from 

discharge-related activities include the storage of materials and land disturbances associated with 

stormwater management-related activities (e.g., the installation or placement of stormwater control 

measures).

a. Select the applicable statement(s) below and follow the corresponding instructions: 

There are no discharge-related activities that are planned to occur during my coverage under 

the MSGP. You can conclude that your discharge-related activities will have no likely adverse 

effects, and:

- If there are any aquatic or aquatic-dependent species and/or their critical habitat in your 

action area, you must skip to Section V, Evaluation of Discharge-Related Activities, below. 

- If there are no aquatic or aquatic-dependent species you may skip to Section VI and verify that 

your activities will have no likely adverse affects. You must submit this worksheet to EPA and the 

Services as specified in Section VII of this worksheet. You may select criterion C on your NOI and 

submit your NOI for permit coverage 30 days after you have submitted this worksheet. You must 

also provide a description of the basis for the criterion you selected on your NOI form, including 

the species and critical habitat list(s), as well as this worksheet and any other documentation 

supporting your eligibility. You must also include this completed Criterion C worksheet in your 

SWPPP.

 There are discharge-related activities planned as part of the proposal. Describe your dischargerelated activities in the following box and continue to b below. 

Describe these activities:

b. In order to ensure any discharge-related activities will have no likely adverse affects on listed 

species and/or their designated critical habitat, you must certify that all the following area true: 

Discharge-related activities will occur:

• on previously cleared/developed areas of the site where maintenance and operation of the 

facility are currently occurring or where existing conditions of the area(s) in which the 

discharge-related activities will occur precludes its use by listed species (e.g., work on 

existing impervious surfaces, work occurring inside buildings, area is not used by species), 

and

Page E-11
Proposed 2013 MSGP

• if discharge-related activities will include establishment of structures (including but not limited 

to infiltration ponds and other controls)or any related disturbances, these structures and/or 

disturbances will be sited in areas that will not result in isolation or degradation of nesting, 

breeding, or foraging habitat or other habitat functions for listed animal species (or their 

designated critical habitat), and will avoid the destruction of native vegetation (including 

listed plant species).

If vegetation removal (e.g., brush clearing) or other similar activities will occur, no terrestrial listed 

species that use these areas for habitat would be expected to be present during vegetation 

removal. 

- If all the above are true, you can conclude that your discharge-related activities will have no 

likely adverse affects, and:

- If there are any aquatic or aquatic-dependent species and/or critical habitat in your action 

area, you must skip to Section V, Evaluation of Discharge-Related Activities, below.

- If there are no aquatic or aquatic-dependent species you may skip to Section VI and verify 

that your activities will have no likely adverse affects. You must submit this worksheet to EPA 

and the Services as specified in Section VII of this worksheet. You may select criterion C on 

your NOI and submit your NOI for permit coverage 30 days after you have submitted this 

worksheet. You must also provide a description of the basis for the criterion you selected on 

your NOI form, including the species and critical habitat list(s), as well as this worksheet and 

any other documentation supporting your eligibility. You must also include this completed 

Criterion C worksheet in your SWPPP.

- If any of the above are not true, you cannot conclude that your discharge-related activities will 

have no likely adverse affects. You must complete the rest of this worksheet (if applicable), and 

must submit the worksheet to EPA and the Services for assistance in determining your eligibility for 

coverage. 

SECTION V. EVALUATION OF DISCHARGE EFFECTS

Note: You are only required to fill out this section if your facility’s action area includes aquatic and/or 

aquatic-dependent species and/or their critical habitat.

In this section, you will evaluate the likelihood of adverse effects from your facility’s discharges. The 

scope of effects to consider will vary with each facility and species/critical habitat characteristics. 

The following are examples of discharge effects you should consider:

• Hydrological Effects. Stormwater discharges may adversely affect receiving waters from 

pollutant parameters such as turbidity, temperature, salinity, or pH. These effects will vary with 

the amount of stormwater discharged and the volume and condition of the receiving water. 

Where a stormwater discharge constitutes a minute portion of the total volume of the 

receiving water, adverse hydrological effects are less likely. 

• Toxicity of Pollutants. Pollutants in stormwater may have toxic effects on listed species and 

adversely affect critical habitat. Exceedances of benchmarks, effluent limitation guidelines, 

or state or tribal water quality requirements may be indicative of potential adverse affects 

on listed species or critical habitat. However, some listed species may be adversely affected 

at pollutant concentrations below benchmarks, effluent limitation guidelines, and state or 

tribal water quality standards. In addition, stormwater pollutants identified in Part 5.2.3.2 of 

your SWPPP, but not monitored as benchmarks or effluent limitation guidelines, may also 

adversely affect listed species and critical habitat.

As these effects are difficult to analyze for listed species, their prey, habitat, and designated critical 

habitat, this worksheet helps you to analyze your discharges and make a determination of whether 

Page E-12
Proposed 2013 MSGP

your discharges will have likely adverse affects and whether there are any additional controls you 

can implement to ensure no likely adverse affects. 

A. Evaluation of Pollutants and Controls to Avoid Adverse Affects. In this section, you must document all of your 

pollutant sources and pollutants expected to be discharged in stormwater. You must also document the controls you will 

implement to avoid adverse affects on listed aquatic and aquatic-dependent species. You must include specific details 

about the expected effectiveness of the controls and your determination of whether the pollutants will be controlled to 

avoid adverse affects to the listed aquatic-and aquatic-dependent species identified in Step 2. 

Pollutant Source Pollutants Controls to Avoid Adverse Affects on Listed Aquatic 

and Aquatic-Dependent Species. Include a detailed 

analysis of why the control(s) will ensure no adverse affects, 

including any data you have about the effectiveness of the 

control in reducing pollutant concentrations. You may also 

attach photos of your controls to this worksheet.

Page E-13
Proposed 2013 MSGP

 Check if you are not able to make a preliminary determination that any of your pollutants will be 

controlled to a level necessary to avoid adverse affects on aquatic and/or aquatic-dependent listed 

species and their designated critical habitat. You must check in Section VI that you are unable to make a 

determination of no likely adverse affects, and must complete the rest of the worksheet. You must submit 

your completed worksheet to EPA and the Services for assistance in determining your eligibility for coverage. 

You may not file your NOI for permit coverage until you are able to make a determination that your 

discharges will avoid adverse affects on listed species and designated critical habitat. 

B. Analysis of Effects Based on Past Monitoring Data. Select which of the following applies to your facility:

I have no previous monitoring data for my facility because there are no applicable monitoring 

requirements for my facility’s sector(s). 

 I have no previous monitoring data for my facility because I am a new discharger, but I am subject to 

monitoring under the 2013 MSGP. You must provide information to support a conclusion that your facility’s 

discharges are not expected to result in benchmark or numeric effluent limit exceedances that will adversely 

affect listed species or their critical habitat:

My facility has not had any exceedances under the 2008 MSGP of any required benchmark(s) or numeric 

effluent limits. 

My facility has had exceedances of one or more benchmark(s) or numeric effluent limits under the 2008 

MSGP, but I have addressed them during my coverage under the 2008 MSGP, or in my evaluation of controls 

to avoid adverse affects in A above. Describe all actions (including specific controls) that you will implement 

to ensure that the pollutants in your discharge(s) will not result in adverse affects from future exceedances.

Check if your facility has had exceedances of one or more benchmarks or numeric effluent limits under 

the 2008 MSGP and you have not been able to address them to adverse affects from future exceedances, 

or if you are a new discharger but you are not sure if you can avoid adverse affects from possible 

exceedances. You must check in Section VI that you are unable to make a determination of no likely 

adverse affects. You must submit your completed worksheet to EPA and the Services for assistance in 

determining your eligibility for coverage. You may not file your NOI for permit coverage until you are able to 

make a determination that your discharges will avoid adverse affects on listed species and designated 

critical habitat.

SECTION VI VERIFICATION OF PRELIMINARY EFFECTS DETERMINATION

Based on Steps I – V of this worksheet, you must verify your preliminary determination of whether your 

discharges and/or discharge-related activities effects on listed species and designated critical 

habitat:

Following the applicable Steps in I – V above, I have made a preliminary determination that my discharges 

and/or discharge-related activities are not likely to adversely affect listed species and designated critical 

habitats.

Following the applicable Steps in I – V above, I am not able to make a preliminary determination that my 

discharges and/or discharge-related activities are not likely to adversely affect listed species and designated 

critical habitats.

SECTION VII WORKSHEET SUBMISSION INSTRUCTIONS

If you have been directed to this section, then you must submit this completed worksheet to 

EPA and the Services, including any attachments and any additional information that 

demonstrates how you will avoid or eliminate adverse effects to listed species or critical 

habitat (e.g., specific controls you will implement to avoid or eliminate adverse effects). Any 

missing or incomplete information may result in a delay on your coverage under the permit. 

If you have made a preliminary determination that your discharges and/or dischargerelated activities will not likely affect listed species and critical habitat, this worksheet must 

be submitted a minimum of 30 days prior to submitting your NOI for permit coverage under 

criterion C. Please note that during either the initial 30-day time period, or within 30 days 

after your NOI submission and before you have been authorized for permit coverage, EPA 

may advise you whether additional information is needed, or whether there are additional 

controls you must implement to avoid adverse effects.

If you are unable to make a preliminary determination that your discharges and/or 

discharge-related activities will not likely affect listed species and critical habitat, this 

worksheet must be submitted to EPA and the Services, but you may not file your NOI for 

permit coverage until you have coordinated with EPA and the Services and received a 

determination from EPA that your discharges and/or discharge-related activities will not likely 

affect listed species and critical habitat.

Appendix F 

Procedures Relating to Historic Properties Preservation

Page F-17
Proposed 2013 MSGP

F. 1 Background

Section 106 of the National Historic Preservation Act

(NHPA) requires Federal agencies to take into account the 

effects of Federal “undertakings”, such as the issuance of 

this permit, on historic properties that are either listed or 

eligible for listing on the National Register of Historic Places. 

To address any issues relating to historic properties in 

connection with the issuance of this permit, EPA has 

developed the screening process in this appendix that 

enables facility operators to appropriately consider the 

potential impacts, if any, from the installation of stormwater 

controls that involve subsurface disturbance, on historic 

properties and to determine whether actions can be 

taken, if applicable, to mitigate any such impacts. 

Although the coverage of individual industrial facilities

under this permit does not constitute separate Federal 

undertakings, the screening process in this appendix 

provides an appropriate site-specific means of addressing 

historic property issues in connection with EPA’s issuance of 

the permit. 

Before an operator is eligible for coverage under 

the 2013 MSGP (unless otherwise noted, all references to 

“eligible” or “eligibility” refer only to coverage under the 

2013 MSGP), the operator must meet one of the 

certification criteria related to historic properties included 

in the permit. In the event an operator cannot meet any of 

the certification criteria included in the permit relating to 

historic properties, the operator must apply for an individual 

permit.

Activities Associated with the MSGP that have No Potential to Cause an Effect on Historic 

Properties

The purpose of the MSGP is to control pollutants that may be discharged in stormwater to 

waters of the United States from certain industrial facilities. EPA does not anticipate effects on 

historic properties from the pollutants in the discharges of stormwater and allowable nonstormwater from industrial facilities. Thus, to the extent EPA’s issuance of this general permit 

authorizes discharges of such constituents, confined to existing stormwater channels or natural 

drainage areas, the permitting action does not have the potential to cause effects on historic 

properties. 

Activities Associated with the MSGP that have Potential to Cause an Adverse Effect on Historic 

Properties

EPA requires permittees to implement controls to reduce pollutants in their discharges. 

The majority of controls implemented for industrial activites are pollution prevention practices, 

e.g., good housekeeping or performing industrial activities in covered areas. In some cases, 

physical controls such as a swale or a retention pond may need to be constructed and/or 

installed to achieve permit compliance. It is the installation of controls that involve subsurface 

Key Terms

Historic Property – Prehistoric or historic districts, 

sites, buildings, structures, or objects that are 

included in or eligible for inclusion in the 

National Register of Historic Places, including 

artifacts, records, and remains that are related 

to and located within such properties.

ACHP – Advisory Council on Historic 

Preservation; an independent Federal agency.

SHPO – The State Historic Preservation Officer for 

a particular state. 

THPO or Authorized Tribal Representative – The 

Tribal Historic Preservation Officer for a 

particular Tribe, or if there is no THPO, the 

representative designated by such Tribe for 

NHPA purposes. Historic properties could have 

significance to more than one Indian tribe; 

therefore, all Indian tribes that attach religious 

and cultural significance to a historic property 

must be identified and included in the historic 

properties screening process. 

Area of Potential Effects (APE) – The geographic 

area or areas within which an undertaking may 

directly or indirectly cause changes in the 

character or use of historic properties, if any 

such properties exist. The area of potential 

effects is influenced by the scale and nature of 

an undertaking and may be different for 

different kinds of effects caused by the 

undertaking. 

Page F-18
Proposed 2013 MSGP

disturbance, also referred to as “discharge-related activities”, that may have a potential to 

cause an adverse effect on historic properties. 

The types of control measures that are presumptively expected to cause subsurface 

ground disturbance include, but are not limited to, the following:

• catch basins, drainage inlets

• pipes, culverts 

• dikes

• ponds, bioretention areas

• ditches, trenches, channels, swales

• land manipulation: contouring, sloping and grading

• perimeter drains

• stormwater injection wells

• manufactured treatment devices (e.g., particle separators, oil/water separators)

In the MSGP, discharge-related activities as applied to the construction, installation or 

alteration of subsurface controls are limited in size to less than one acre of subsurface 

disturbance (except for mining activities covered under Sectors G, H, J in which all sizes of earth 

disturbance are covered by the MSGP). Controls involving ground disturbances of one acre 

(except mining) or more generally require coverage under a different permit, the Construction 

General Permit. 

Therefore, any new or existing facility seeking coverage under this permit that intends to 

install new subsurface controls must determine, following the procedures in this appendix, 

whether there are any historic properites within the area of potential effect (APE), and, in 

coordination with the EPA and appropriate SHPO, THPO or an authorized tribal representative, 

whether the subsurface controls will have the potential to cause an adverse effect on historic 

properties. If there are potential adverse effects, the operator must, in coordination with the EPA 

and appropriate SHPO, THPO or an authorized tribal representative, determine measures to 

mitigate or prevent the adverse effects. Alternatively, an operator may substitute controls that 

comply with permit requirements which do not involve subsurface disturbances (e.g., directing 

runoff via surface-only berms or diversions in lieu of digging trenches). 

F.2 Historic Properties Eligibility Criteria 

Prior to submitting your Notice of Intent (NOI) for permit coverage, you must determine 

which of the following eligibility criteria (A – D) best applies to your facility (if none of the four 

criteria apply, you cannot submit an NOI and you must apply for an individual stormwater 

permit). To help make your criterion selection, you must follow the historic properties screening 

procedures in this appendix, and then enter the criterion on your NOI. 

After submitting your NOI, and during the 30-day waiting period, the public, ACHP, or 

SHPO, THPO, or an authorized tribal representative may request that EPA place a hold on 

authorization based upon concerns regarding potential adverse effects to historic properties. 

EPA, in coordination with the ACHP and/or SHPO, THPO, or an authorized tribal representative 

will evaluate any such request and notify you whether any additional measures to address 

potential adverse effects to historic properties are necessary.

Page F-19
Proposed 2013 MSGP

Criterion A. There is no potential of an adverse effect on historic properties because there will 

be no new subsurface control measures (which include stormwater 

conveyances) constructed or installed.

Criterion B. There are no historic properties or properties eligible for listing in the National 

Register of Historic Places within the area of potential effects (APE).

Criterion C. My subsurface stormwater controls have the potential to cause adverse effects 

on historic properties. After contacting in writing the EPA Regional office and the 

appropriate SHPO, THPO or an authorized tribal representative, I have 

coordinated with the SHPO, THPO or an authorized tribal representative (or EPA in 

coordination with the SHPO, THPO or an authorized tribal representative), and I 

received a written conclusion that my subsurface stormwater controls will not 

cause adverse effects on historic properties; or I have entered into a written 

agreement with the SHPO, THPO or an authorized tribal representative (or EPA in 

coordination with the SHPO, THPO or an authorized tribal representative)

regarding measures required to mitigate or prevent adverse effects on historic 

properties.

Criterion D. My subsurface stormwater controls have the potential to cause adverse effects 

on historic properties. I have contacted both the EPA Regional office and the 

SHPO, THPO or an authorized tribal representative in writing, and EPA provided 

the additional measures, if any, required for me to be eligible for permit 

coverage. 

F.3 Steps for Establishing Eligibility Regarding Protection of Historic Properties

The questions and procedures in the following steps must be considered and complied 

with, as applicable, by all operators seeking to establish eligibility for coverage under the 2013 

MSGP. 

Step One: Was your facility eligible for coverage under the 2008 MSGP and have you 

retained your eligibility and compliance with that permit? 

If your answer is no or you are a new facility, proceed directly to Step Two. 

As an existing facility, you should have previously addressed historic properties issues 

when establishing your eligibility for coverage under the 2008 permit. You had to certify there 

was not an adverse effect to historic properties or you had obtained a written agreement from 

the appropriate SHPO or THPO regarding methods for mitigating potential impacts. If historic 

properties are known to exist within your APE as a result of compliance with previous versions of 

the MSGP or other stormwater permit, you must document any actions you took to mitigate or 

eliminate your potential to cause an adverse effect on historic properties.

A historic properties-related agreement and/or additional requirements given to you in 

order to become eligible for coverage under the 2008 MSGP will be considered your eligibility 

requirements for the 2013 MSGP, provided you will not construct, install or alter any subsurface 

stormwater control measures during the term of the permit. If you will not construct, install or alter 

any subsurface stormwater control measures during the term of the permit, then you may select 

eligibility Criterion A on your NOI form and you have no further obligations relating to historic 

properties. 

Page F-20
Proposed 2013 MSGP

Step Two: Are you constructing, installing or altering any stormwater control measures that 

involve subsurface disturbance of less than one acre

If your answer is yes, then proceed to Step Three.

As in Step One, if your compliance with this permit will not involve building, installing or 

altering subsurface control measures, then you may select eligibility Criterion A on your NOI form 

and you have no further obligations relating to historic properties. However, if at any time during 

the permit term you determine a subsurface control measure is needed and you initially chose 

eligibility Criterion A, you must ensure your eligibility for continued authorization to discharge is 

maintained before any subsurface disturbance occurs by performing the procedures in Step 

Three through Five.

Step Three: Within your APE determine whether: a) there is a property listed in the National 

Register of Historic Places; or b) prior earth disturbances, surveys or other activity 

revealed the existence of a historic property or provided evidence that a historic 

property may exist.

Under this step your must consider the APE associated with your subsurface disturbance

for both of the cases a) and b) below. The APE for your discharge-related activities is limited to 

the area where you construct, install or alter subsurface controls to comply with the MSGP. 

Therefore, you only need consider the location of the actual subsurface disturbance and the 

depth of the disturbance (i.e., for a swale that you excavated down to one foot, you only need 

consider the presence of historic properties down to one foot).

a) Determine whether your APE includes any portion of a property listed in the National 

Register of Historic Places. Listed properties can be identified via the National Register of Historic 

Places website at www.nps.gov/nr/. Note the National Register of Historic Places website may 

not be upto-date or that the connection between your APE and a listed historic property may 

not be apparent. For any questions regarding listings in the National Register of Historic Places 

you should contact your SHPO, THPO or an authorized tribal representative. 

If the result of your inquiry is yes then proceed to Step Five. If no, you must still consider 

whether part b) below applies to your site.

b) Determine whether any prior earth disturbance (disturbances do not need to be 

related to compliance with a stormwater permit), prior survey of historic resources, or other 

activity has revealed the presence of historic properties (which includes properties eligible for 

listing in the National Register of Historic Places) or provided other evidence that a National 

Register-eligible historic property may exist within your APE. Evidence that a National Registereligible historic property may exist includes any artifacts, records or remains that may have been 

found indicating the presence of a potential historic property even though such evidence or 

property has not yet been evaluated for eligibility for listing in the National Register of Historic 

Places. Be aware that discovery of human remains may trigger separate requirements under 

state law or the federal Native American Graves Protection and Repatriation Act (NAGPRA), but 

any such requirements are not associated with MSGP permit eligibility.

 If a prior earth disturbance, survey, or other activity has revealed the presence of historic 

properties or other evidence that a National Register-eligible historic property may exist within 

your APE proceed to Step Five. 

Page F-21
Proposed 2013 MSGP

Alternatively, if you substitute or modify your activities to eliminate any controls involving

subsurface disturbance, you may select eligibility Criterion A on your NOI form and you have no 

further obligations relating to historic properties. 

If a prior earth disturbance, survey, or other activity has not conclusively revealed the 

existence of historic properties or other evidence that a National Register-eligible historic 

property may exist within your APE, or if there has been no prior earth disturbance, survey, or 

other activity with which to make this assessment, then proceed to Step Four.

Step Four: Determine whether any historic properties identified in Step Three may be 

located within your APE in coordination with your SHPO, THPO or an authorized 

tribal representative, or by retaining a qualified consultant in the historical or 

archaeological fields.

Step Four assumes that the APE for your intended subsurface control measures does not 

include any site listed in the National Register of Historic Places and that a prior earth 

disturbance, survey, or other activity has not revealed the presence of historic properties or other 

evidence that a National Register-eligible historic property may exist within your APE. In these 

circumstances, you must still determine, in coordination with the the relevant SHPO, THPO or 

authorized tribal representative or a qualified professional consultant, whether any properties 

eligible for listing in the National Register of Historic Places exist within your APE.

You may contact your appropriate SHPO, THPO or an authorized tribal representative to 

request their help in determing the presence of historic properties, or alternatively, you may opt 

to contact a qualified consultant in the historical or archaeological fields without first contacting 

the SHPO, THPO or an authorized tribal representative. If the SHPO, THPO or an authorized tribal 

representative indicates to you within 15 calendar days after your contact that they are unable 

to provide you assistance, then you must engage the services of a qualified professional 

consultant. If the SHPO, THPO or an authorized tribal representative does not respond within 15 

days after your contact, you may assume there are no historic properties or National Register of 

Historic Places-eligible property within your APE, and you may certify your eligibility under 

Criterion B on your NOI form, and you have no further obligations relating to historic properties. 

The SHPO, THPO or an authorized tribal representative and/or a qualified professional 

consultant can assist your analysis and determination in many ways, including examining local 

records to determine whether historic artifacts have been found in nearby areas, conducting 

surveys of your APE, and performing limited surface and subsurface examinations. Your historic

resource survey assistance provider and results must be documented and retained per Part 

5.2.6.2 of the MSGP. 

If, after completion of a historic resource survey, you determine there are no historic 

properties within your APE, you may select eligibility Criterion B. If you determine there are, or

may be, historic properties within your APE, continue to Step Five.

Alternatively, if you substitute or modify your activities to eliminate any controls involving

subsurface disturbance, you may select eligibility Criterion A on your NOI form and you have no 

further obligations relating to historic properties.

Page F-22
Proposed 2013 MSGP

Step Five: Contact the EPA and appropriate historic preservation authorities. 

If you intend to build, install or alter subsurface control measures, you must contact in 

writing (which may include using email) EPA and also the relevant SHPO, THPO or an authorized 

tribal representative if any of the following circumstances apply within your APE: 

• There is a property listed or eligible for listing in the National Register of Historic Places;

• A prior earth disturbance, survey, or other activity provided evidence that a National

Register-eligible historic property may exist;

• You wish to begin the process for nominating a property in the National Register.

Contact with all parties should be made as soon as possible, but in no event less than 30

days before you submit your NOI. Your written correspondence must advise them that you are 

seeking coverage under EPA’s industrial stormwater permit and that one of the circumstances 

listed in the bullets in Step Five is applicable. Your requirements for each of the circumstances 

are as follows. If you do not receive a response from either EPA or your SHPO, THPO or an 

authorized tribal representative within 15 days after making contact with both parties, you may 

select eligibility Criterion C on your NOI form and you have no further obligations relating to 

historic properties.

For when you have a property listed or eligible for listing in the National Register of Historic 

Places:

You must coordinate with EPA and the SHPO, THPO or an authorized tribal representative 

regarding the determination of whether your construction, installation or alteration of subsurface 

control measures will have any adverse effects on historic properties / properties eligible for 

listing in the National Register of Historic Places, and if so, to discuss appropriate measures to 

mitigate or prevent such effects. You must provide all relevant information in your written 

correspondence necessary to facilitate an effects determination (the nature of the historic 

property, size and location of the subsurface disturbance, etc.).

For when a prior earth disturbance, survey, or other activity provided evidence that a National 

Register-eligible historic property may exist:

When you have evidence such as artifacts, records or remains that are not associated 

with a property listed in the National Register of Historic Places, you must coordinate with EPA 

and the SHPO, THPO or an authorized tribal representative regarding whether the property is 

eligible for listing in the National Register of Historic Places. You must provide all relevant 

information and evidence in your written communication necessary to make eligibility 

determinations.

To begin the process for nominating a property for listing in the National Register: 

The nominating process begins with contacting the SHPO, THPO or an authorized tribal 

representative. Properties eligible for listing must meet certain criteria, found in the National 

Register Criteria for Evaluation, at www.nps.gov/nr/publications/bulletins/nrb15/nrb15_2.htm. 

Basically, this involves examining the property’s age, integrity and significance.

• Age and Integrity: Is the property old enough to be considered historic (generally at

least 50 years old) and does it still look much the way it did in the past?

Page F-23
Proposed 2013 MSGP

• Significance: Is the property associated with events, activities, or developments that

were important in the past? With the lives of people who were important in the past?

With significant architectural history, landscape history, or engineering achievements?

Does it have the potential to yield information through archeological investigation about

our past?

Following your contact with EPA and SHPO, THPO or an authorized tribal representative: 

If, in response to your written correspondence or as part of any additional coordination, 

the SHPO, THPO or an authorized tribal representative (or EPA in coordination with your SHPO, 

THPO or an authorized tribal representative) provides a written conclusion that your subsurface 

stormwater controls will have no adverse effect or historic properties, you have met eligibility 

Criterion C. You must retain a copy of the SHPO, THPO or an authorized tribal representative’s 

written conclusion consistent with Part 5.2.6.2 of the MSGP. You must also file a copy of that 

written conclusion with the ACHP within 14 days of receiving it. You may then select eligibility 

Criterion C on your NOI form and you have no further obligations relating to historic properties. 

If potential adverse effects on historic properties are identified and if, as a result of your 

coordination with the SHPO, THPO or an authorized tribal representative (or EPA in coordination 

with your SHPO, THPO or an authorized tribal representative), you enter into and comply with a 

written agreement with the SHPO, THPO or an authorized tribal representative on how to address 

(i.e., through elimination or mitigation) such potential adverse effects, you may then select 

eligibility Criterion C on your NOI form and you must retain a copy of the written agreement 

consistent with Part 5.2.6.2 of the MSGP. You have no further obligations relating to historic 

properties. 

If potential adverse effects on historic properties are identified but following appropriate 

coordination with the SHPO, THPO or an authorized tribal representative (or EPA in coordination 

with SHPO, THPO or an authorized tribal representative), you cannot come reach an agreement 

regarding appropriate measures to mitigate or eliminate such effects, you should alert EPA 

about the lack of agreement. EPA will work with you and the SHPO, THPO or an authorized tribal 

representative, and the ACHP to develop an agreement to address any adverse effects. Until 

an agreement is reached, you may not submit your NOI. 

If agreement with historic preservation authorities (the SHPO, THPO or an authorized tribal 

representative and also, potentially, the ACHP, as necessary) cannot be reached, EPA may 

require you to obtain coverage under an individudal permit. Alternatively, EPA may determine 

what additional measures, if any, are required for you to become elgible for MSGP coverage. 

After you comply with any such additional measures you must document your compliance and 

retain such documentation consistent with Part 5.2.6.2 of the MSGP. If no additional measures 

are required for you to become elgible for permit coverage, retain the written statement from 

EPA informing you of this per Part 5.2.6.2 of the MSGP. You may then select eligibility Criterion D 

on your NOI form and you have no further obligations regarding historic properties.

After submittal of your NOI:

After you submit your NOI there is a 30-day waiting period during which the public, 

ACHP, SHPO, THPO or an authorized tribal representative may review your NOI and request that

EPA delay your permit authorization based on concerns about potential adverse impacts to 

historic properties. EPA will evaluate any such delay request and will coordinate with the SHPO, 

THPO or an authorized tribal representative, and/or ACHP, as necessary to address potential 

adverse effects to historic properties. As in the options and process described above under the 

Page F-24
Proposed 2013 MSGP

“Following your contact with EPA and SHPO, THPO or an authorized tribal representative

section”, EPA may require that additional measures be implemented for you to become elgible 

for permit coverage, or the Agency may require you to obtain coverage under an individudal 

permit. If you have previously entered into a written agreement with the SHPO, THPO or an 

authorized tribal representative addressing impacts on historic properties, EPA would generally 

accept any such written agreement as addressing such concerns unless new information was 

brought to the Agency’s attention that was not considered in your previous discussions with the 

SHPO, THPO or an authorized tribal representative.

Historic Preservation Authorities Contact Information

Addresses for State Historic Preservation Officers and Tribal Historic Preservation Officers 

may be found on the Advisory Council on Historic Preservation’s website 

(www.achp.gov/programs.html). In instances where a Tribe does not have a Tribal Historic 

Preservation Officer, you should contact the appropriate Tribal government office when 

addressing permit eligibility requirements relating to historic properties.

A for the definition of new discharger). If you are not a new 

discharger, you must indicate whether stormwater discharges from 

your facility have been previously covered under another NPDES 

permit. If yes, you must provide the unique NPDES ID (i.e., permit 

tracking number) for the previous permit your facility was covered 

under.

Section C. Facility Operator Information

Provide the legal name of the person, firm, public organization, or 

any other entity that operates the facility described in this 

application. An operator of a facility is the legal entity that controls 

the operation of the facility. Refer to Appendix A of the permit for 

the definition of “operator”. Provide the operator’s mailing address, 

phone number, and e-mail. Correspondence for the NOI will be sent 

to this address. Also provide the name and title for the operator 

point of contact (note that the point of contact name may be the 

same as the operator name).

If the NOI was prepared by someone other than the certifier (for 

example, if the NOI was prepared by the facility SWPPP contact or a 

consultant for the certifier’s signature), include the full name, 

organization, phone number, and email address of the NOI preparer.

Section D. Facility Information

Enter the official or legal name and complete street address, including 

city, state, ZIP code, and county or similar government subdivision of

location of the facility (e.g., Intersection of State Highways 61 and 34). 

Complete facility information must be provided for permit coverage to 

be granted.

Provide the latitude and longitude of your facility in degrees decimal 

format. The latitude and longitude of your facility can be determined 

in several different ways, including through the use of global 

positioning system (GPS) receivers, U.S. Geological Survey (U.S.G.S.) 

topographic or quadrangle maps, and EPA’s web-based siting tools, 

among others. Refer to 

http://transition.fcc.gov/mb/audio/bickel/DDDMMSS-decimal.html/ for 

assistance in providing the proper latitude/longitude format. For 

consistency, EPA requests that measurements be taken form the 

approximate center of the facility. Specify which method you used to

determine latitude and longitude. If a U.S.G.S. topographic map is 

used, specify the scale of the map used. Enter the horizontal reference 

datum for your latitude and longitude. The horizontal reference datum 

used on USGS topographic maps is shown on the bottom left corner of 

USGS topographic maps; it is also available for GPS receivers.

For Sector S facilities (Air Transportation), indicate whether you 

anticipate that the entire airport facility will use more than 100,000 

gallons of glycol-based deicing/anti-icing chemicals and/or 100 

tons or more of urea on an average annual basis. If so, additional 

effluent limits and monitoring conditions apply to your discharge 

(see Part 8 Sector S of the permit). 

Indicate whether your facility is currently inactive and unstaffed. 

Note that if your facility becomes inactive and unstaffed during the 

permit term, you must submit an NOI modification to reflect the 

change.

Section E. Discharge Information

Indicate whether you are you seeking coverage under this permit 

for any discharges other than stormwater discharges and the 

allowable non-stormwater discharges listed in Part 1.1.3. Note that 

The MSGP only authorizes the allowable stormwater discharges in 

Part 1.1.2 and the allowable non-stormwater discharges in Part 1.1.3. 

Any discharges not expressly authorized under the MSGP are not 

covered by the MSGP or the permit shield provision of the CWA 

Section 402(k) and they cannot become authorized or shielded by 

disclosure to EPA and/or state via the Notice of Intent to be 

covered by the permit or by any other means (e.g., in the 

Stormwater Pollution Prevention Plan or during an inspection). If any 

discharges requiring NPDES permit coverage other than the 

allowable stormwater and non-stormwater discharges listed in Parts 

1.1.2 and 1.1.3 will be discharged, they must be covered under 

another NPDES permit.

Depending on your industrial activities, your facility may be subject 

to effluent limitation guidelines which include additional effluent 

limits and monitoring requirements for your facility. Please review 

these requirements, described in Part 2.1.3 of the MSGP, and check 

any appropriate boxes on the NOI form.

You must identify all the outfalls from your facility that discharge 

stormwater. Each outfall must be assigned a unique 3-digit number 

(e.g., 001). You must also provide the latitude and longitude for each 

outfall from your facility. You must also indicate whether any outfalls 

are substantially identical to an outfall already listed, and identify the 

outfall it is identical to. For each outfall you list, you must specify the 

names of any waters of the U.S. that receive stormwater directly from 

the outfall and/or from the MS4 that the outfall discharges to. You 

must also specify whether any receiving waters that you discharge to 

are listed as ”impaired” as defined in Appendix A, and the pollutants 

for which the water is impaired. You must also check whether a Total 

Maximum Daily Load (TMDL) has been completed any of the waters 

of the U.S. that you discharge to. You must also provide information 

about the outfall latitude/longitude, including data source, the scale 

(if applicable), and the horizontal reference datum. See the 

instructions in Section D for more information about determining the 

latitude and longitude. 

Identify whether your facility discharges into a Municipal Separate 

Storm Sewer System (MS4). If yes, provide the name of the MS4 

operator. If you are uncertain of the MS4 operator, contact your local 

government for that information. 

Indicate whether discharges from the facility will enter into a water of 

the U.S that is designated as a Tier 2, Tier 2.5, or Tier 3 water. A list of Tier 

2, 2.5, and 3 waters is provided as Appendix L. If the answer is “yes”, 

name all waters designated as Tier 2, Tier 2.5, or Tier 3 to which the 

facility will discharge. Note that you are ineligible for coverage if you 

are a new discharger to waters designated as Tier 3 (outstanding 

natural resource waters) for antidegradation purposes under 40 CFR 

131.13(a)(3).

If you are subject to any benchmark monitoring requirements (see the 

requirements applicable to your Sector in Part 8 of the permit), 

indicate the hardness for your receiving water(s). See Appendix J of 

the permit for information about determining waterbody hardness

If you are subject to benchmark monitoring requirements for metals 

you must also answer whether your facility discharges into any 

saltwater receiving waters. 

Indicate whether your facility will discharge into a receiving water that 

is part of a federal CERCLA site (as defined in Appendix A). Refer to the 

list of federal CERCLA sites that include a waterbody cleanup are 

provided in Appendix P of the permit. Note that if your facility will 

discharge into a federal CERCLA site, you are not eligible for coverage 

under this permit unless you notify your applicable EPA Regional Office 

in advance and the EPA office authorizes overage under this permit 

after you have included appropriate controls and implementation 

procedures designed to ensure that discharges will not lead to 

recontamination of aquatic media at the CERCLA site. 

Section F. Stormwater Pollution Prevention Plan (SWPPP) Information

All facilities eligible for coverage under this permit are required to 

prepare a SWPPP in advance of filing the NOI, in accordance with Part 

5. Indicate whether the SWPPP has been prepared in advance of filing 

the NOI. 

Indicate the contact information (name, phone, and email) for the 

person who developed the SWPPP for this facility. 

You identify how your SWPPP information will be made available, 

consistent with Part 5.4.1 and 7.3 of the permit. If you are making your 

SWPPP publicly available on a web site, check Option 1 and provide 

the appropriate Internet URL address. If you are not providing a URL, 

check Option 2 and provide the selected SWPPP information on this 

NOI form. You may copy and paste this information directly from your 

SWPPP. 

Section G. Endangered Species Protection

Using the instructions in Appendix E, indicate under which endangered 

species criterion listed in Part 1.1.4.5 of the permit (i.e., A, B, C, D, or E) 

you are eligible with regard to the protection of federally listed 

endangered and threatened species and designated critical habitat. 

A description of the basis for the criterion selected must also be 

provided.

If criterion B is selected, provide the NPDES ID (i.e., permit tracking 

number) for the other operator who has certified their eligibility under 

this permit. The NPDES ID was assigned when the operator received 

coverage under this permit.

Calculating Hardness in Receiving Waters for Hardness Dependent Metals

Proposed 2013 MSGP

Appendix J. Calculating Hardness in Freshwater Receiving Waters for Hardness Dependent 

Metals

Overview

For any sectors required to conduct benchmark samples for a hardness-dependent metal, EPA 

includes ‘hardness ranges’ from which benchmark values are determined. To determine which 

hardness range to use, you must collect data on the hardness of your receiving water(s). Once 

the site-specific hardness data have been collected, the corresponding benchmark value for 

each metal is determined by comparing where the hardness data fall within hardness ranges, as 

shown in Table 1. You only need to determine hardness for your discharges into freshwater as 

the benchmark values for metals do not vary for discharges to saline waters.

Lead, Nickel, Silver, and Zinc.

How to Determine Hardness for Hardness-Dependent Parameters in Freshwater. 

You may select one of three methods to determine hardness, including; individual grab 

sampling, grab sampling by a group of operators which discharge to the same receiving water, 

or using third-party data. Regardless of the method used, you are responsible for documenting 

the procedures used for determining hardness values. Once the hardness value is established, 

you are required to include this information in your first benchmark report submitted to EPA so 

that the Agency can make appropriate comparisons between your benchmark monitoring 

results and the corresponding benchmark. You must retain all report and monitoring data in 

accordance with Part 7.5 of the permit. The three method options for determining hardness are 

detailed in the following sections.

(1) Permittee Samples for Receiving Stream Hardness

This method involves collecting samples in the receiving water and submitting these to a 

laboratory for analysis. If you elect to sample your receiving water(s) and submit samples for 

analysis, hardness must be determined from the closest intermittent or perennial stream 

downstream of your point of discharge. The sample can be collected during either dry or wet 

Page J-2 
Proposed 2013 MSGP

weather. Collection of the sample during wet weather is more representative of conditions 

during stormwater discharges; however, collection of in-stream samples during wet weather 

events may be impracticable or present safety issues.

Hardness must be sampled and analyzed using approved methods as described in 40 

CFR Part 136 (Guidelines Establishing Test Procedures for the Analysis of Pollutants).

(2) Group Monitoring for Receiving Stream Hardness

You can be part of a group of permittees discharging to the same receiving waters and 

collect samples that are representative of the hardness values for all members of the group. In 

this scenario, hardness of the receiving water must be determined using 40 CFR Part 136 

procedures and the results shared by group members. To use the same results, hardness 

measurements must be taken on a stream reach within a reasonable distance of the discharge 

points of each of the group members.

(3) Collection of Third-Party Hardness Data

You can submit receiving stream hardness data collected by a third party provided the 

results are collected consistent with the approved 40 CFR Part 136 methods. These data may 

come from a local water utility, previously conducted stream reports, TMDLs, peer reviewed 

literature, other government publications, or data previously collected by the permittee. Data 

should be less than 10 years old.

Water quality data for many of the nation’s surface waters are available on-line or by 

contacting EPA or a state environmental agency. EPA’s data system STORET, short for STOrage 

and RETrieval, is a repository for receiving water quality, biological, and physical data and is 

used by state environmental agencies, EPA and other federal agencies, universities, private 

citizens, and many others. Similarly, state environmental agencies and the U.S. Geological 

Service (USGS) also have water quality data available that, in some instances, can be accessed 

online. “Legacy STORET” codes for hardness include: 259 hardness, carbonate; 260 hardness, 

noncarbonated; and 261 calcium + magnesium, while more recent, “Modern STORET” data 

codes include: 00900 hardness, 00901 carbonate hardness, and 00902 noncarbonate hardness; 

or the discrete measurements of calcium (00915) and magnesium (00925) can be used to 

calculate hardness. Hardness data historically has been reported as “carbonate,” 

“noncarbonate,” or “Ca + Mg.” If these are unavailable, then individual results for calcium (Ca) 

and magnesium (Mg) may be used to calculate hardness using the following equation:

mg/L CaCO3 = 2.497 (Ca mg/L) + 4.118 (Mg mg/L) 

When interpreting the data for carbonate and non-carbonate hardness, note that total 

hardness is equivalent to the sum of carbonate and noncarbonate hardness if both forms are 

reported. If only carbonate hardness is reported, it is more than likely that noncarbonate 

hardness is absent and the total hardness is equivalent to the available carbonate hardness.

NO EXPOSURE CERTIFICATION (NOE) FOR EXCLUSION FROM EPA’S 

MULTI-SECTOR GENERAL PERMIT FOR STORMWATER DISCHARGES ASSOCIATED WITH 

INDUSTRIAL ACTIVITY (MSGP)

Form Approved 

OMB No. XXXX-XXXX

Submission of this No Exposure Certification constitutes notice that the operator identified in Section B does not require permit authorization under EPA’s 

Stormwater Multi Sector General Permit for its stormwater discharges associated with industrial activity from the facility identified in Section C of this form due to 

the existence of a condition of no exposure.

A condition of no exposure exists at an industrial facility when all industrial materials and activities are protected by a storm resistant shelter to prevent exposure 

to rain, snow, snowmelt, and/or runoff. Industrial materials or activities include, but are not limited to, material handling equipment or activities, industrial 

machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage, loading and 

unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product. A storm resistant shelter is not required for 

the following industrial materials and activities:

– drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak. “Sealed” means 

banded or otherwise secured and without operational taps or valves;

– adequately maintained vehicles used in material handling; and

– final products, other than products that would be mobilized in stormwater discharges (e.g., rock salt).

A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In addition, the exclusion from NPDES permitting is 

available on a facility-wide basis only, not for individual outfalls. If any industrial activities or materials are or will be exposed to precipitation, the facility is not 

eligible for the no exposure exclusion.

By signing and submitting this No Exposure Certification form, the operator in Section II is certifying that a condition of no exposure exists at its facility or site, and 

is obligated to comply with the terms and conditions of 40 CFR 122.26(g).

Associated with Industrial Activity Under an NPDES General Permit

NPDES Form Date (X/13) This Form Replaces From 3510-11 (09/08) Form Approved OMB No. XXXX-XXXX

Who May File a No Exposure Certification

Federal law at 40 CFR Part 122.26 prohibits point source discharges 

of stormwater associated with industrial activity to waters of the 

U.S. without a National Pollutant Discharge Elimination System 

(NPDES) permit. However, NPDES permit coverage is not required 

for discharges of stormwater associated with industrial activities 

identified at 40 CFR 122.26(b)(14)(i)-(ix) and (xi) if the discharger 

can certify that a condition of “no exposure” exists at the industrial 

facility or site.

Stormwater discharges from construction activities identified in 

40 CFR 122.26(b)(14)(x) and (b)(15) are not eligible for the no 

exposure exclusion.

Obtaining and Maintaining the No Exposure Exclusion

This form is used to certify that a condition of no exposure exists at 

the industrial facility or site described herein. This certification is 

only applicable in jurisdictions where EPA is the NPDES permitting 

authority and must be re-submitted at least once every five years.

The industrial facility operator must maintain a condition of no 

exposure at its facility or site in order for the no exposure exclusion 

to remain applicable. If conditions change resulting in the 

exposure of materials and activities to stormwater, the facility 

operator must obtain coverage under an NPDES stormwater 

permit immediately.

Completing the Form

You must type or print, using uppercase letters, in appropriate 

areas only. Enter only one character per space (i.e., between the 

marks). Abbreviate if necessary to stay within the number of 

characters allowed for each item. Use one space for breaks 

between words. One form must be completed for each facility or 

site for which you are seeking to certify a condition of no 

exposure. Please make sure you have addressed all applicable 

questions and have made a photocopy for your records before 

sending the completed form to the above address.

Section A. Approval to Use Paper NOE Form

You must indicate whether you have been granted a waiver from 

electronic reporting from the Regional Office. Note that you are 

not authorized to use this paper NOE form unless the Regional 

Office has approved its use. Where you have obtained approval 

to use this form, indicate the waiver that you have been granted, 

the name of the EPA Regional Office staff person who granted the 

waiver, and the date that approval was provided. See 

www.epa.gov/npdes/stormwater/contacts for a list of EPA

Instructions for Completing EPA Form 3510-11

No Exposure Certification(NOE) for Exclusion from Stormwater Discharges 

Associated with Industrial Activity Under an NPDES General Permit

NPDES Form Date (X/13) This Form Replaces From 3510-11 (09/08) Form Approved OMB No. XXXX-XXXX

Section E. Exposure Checklist

Check “Yes” or “No” as appropriate to describe the exposure 

condition at your facility. If you answer “Yes” to ANY of the 

questions in this section, a potential for exposure exists at your site 

and you cannot certify to a condition of no exposure. You must 

obtain (or already have) coverage under an NPDES stormwater 

permit. After obtaining permit coverage, you can institute 

modifications to eliminate the potential for a discharge of 

stormwater exposed to industrial activity, and then certify to a 

condition of no exposure.

Section F and G. Certification Information

All applications, including NOEs, must be signed as follows:

For a corporation: by a responsible corporate officer, which 

means: (i) president, secretary, treasurer, or vice-president of the 

corporation in charge of the principal business function, or any 

other person who performs similar policy or decision making 

functions, or (ii) the manager of one or more manufacturing, 

production, or operating facilities employing more than 250 

persons or having gross annual sales or expenditures exceeding 

$25 million (in second-quarter 1980 dollars), if authority to sign 

documents has been assigned or delegated to the manager in 

accordance with corporate procedures;

For a partnership or sole proprietorship: by a general partner or 

the proprietor; or

For a municipality, state, federal, or other public agency: By either 

a principal executive officer or ranking elected official. For 

purposes of this Part, a principal executive officer of a federal 

agency includes (i) the chief executive officer of the agency, or 

(ii) a senior executive officer having responsibility for the overall 

operations of a principal geographic unit of the agency (e.g., 

Regional Administrator of EPA).

List of Tier 2, Tier 2.5 and Tier 3 Waters

EPA Form 3510-11 

Page L-1 
Proposed 2013 MSGP

Appendix L - List of Tier 3, Tier 2, and Tier 2.5 Waters

EPA’s MSGP has special requirements for discharges to waters designated by a state or tribe as 

Tier 2/2.5 or Tier 3 for antidegradation purposes under 40 CFR 131.12(a). See Parts 1.1.4.8 and 

1.1.4.10 

The list below is provided as a resource for operators who must determine whether they 

discharge to a Tier 2/2.5 or Tier 3 water. Only Tier 2/2.5 or Tier 3 waters specifically identified by a 

water quality standard authority (e.g., a state, territory, or tribe) are identified in the table below. 

Many authorities evaluate the existing and protected quality of the receiving water on a 

pollutant-by-pollutant basis and determine whether water quality is better than the applicable 

criteria that would be affected by a new discharge or an increase in an existing discharge of 

the pollutant. In instances where water quality is better, the authority may choose to allow lower 

water quality, where lower water quality is determined to be necessary to support important 

social and economic development. Permittees are not required to identify those waters which 

are evaluated on an individual basis.

Section A. Approval to Use Paper MDMR Form

You must indicate whether you have been granted a waiver from 

electronic reporting from the Regional Office. Note that you are 

not authorized to use this paper MDMR form unless the Regional 

Office has approved its use. Where you have obtained approval 

to use this form, indicate the waiver that you have been granted, 

the name of the EPA staff person who granted the waiver, and the 

date that approval was provided. See 

www.epa.gov/npdes/stormwater/contacts for a list of EPA 

Regional Office contacts. 

Section B. Permit Information

Provide the NPDES ID (i.e., NOI tracking number) assigned to your 

facility. 

Indicate your reason(s) for submitting this MDMR by checking all 

boxes that apply. The reasons for submission are defined as follows:

• Submitting monitoring data: For each storm sampled, 

submit one MDMR form with data for all outfalls sampled. 

Select this reason even if you only have monitoring data 

for some of your outfalls (i.e., some outfalls did not 

discharge). If you select this reason you are required to 

complete all Sections of the form.

• Reporting no discharge for all outfalls for this monitoring 

period: Indicates that there were no discharges from all 

outfalls during this monitoring period. If you select this 

reason you are only required to complete Sections A, B, 

C, D, E.1, and G.

• Reporting that your site status has changed to inactive 

and unstaffed: Indicates that your facility is currently 

inactive and unstaffed (See Part 6.2.1.3 of the permit for 

more information). If you select this reason you are only 

required to complete Sections A, B, F and include date of 

status change in comment field in Section F.4

• Reporting that you site status has changed from inactive 

to active: Indicates that your facility is currently active 

(See Part 6.2.1.3 of the permit for more information). If 

you select this reason you are required to complete all 

Sections 

of the form and include date of status change in the 

comment field in Section F.4.

• Reporting that no further reductions are achievable for 

all outfalls and for all pollutants via Part 6.2.1.2 of the 

permit: Indicates that your facility has determined that 

no further pollutant reductions are technologically and 

economically practicable in light of best industry 

practice to meet the technology-based effluent limits or 

are necessary to meet the water-quality-based effluent 

limitations in Parts 2 of the permit (See Part 6.2.1.2 of the 

permit for more information). If you select this reason 

you are required to complete Sections A, B, C and G. 

However, if you can make this finding for some outfalls 

and pollutants, but not for others, you cannot select this 

reason; you will instead be able to identify which outfalls 

and which pollutants you can make this finding for in 

Section F.

Section C. Facility Operator Information.

Provide the legal name of the person, firm, public organization, or 

any other entity that operates the facility described in this 

application. An operator of a facility is the legal entity that 

controls the operation of the facility. Refer to Appendix A of the 

permit for the definition of “operator”. Provide the operator’s 

mailing address, phone number, and e-mail. The operator 

information in this Section should match the operator information 

provided on your NOI form. 

Provide the name, organization, phone number, an email 

address for the person who prepared this MDMR form. 

Section D. Facility Information

Enter the official or legal name and complete street address,

including city, state, ZIP code, and county or similar government 

subdivision of the facility. If the facility lacks a street address, 

indicate the general location of the facility (e.g., Intersection of 

State Highways 61 and 34). Complete facility information must be 

provided for permit coverage to be granted. The facility 

information in this Section should match the facility information 

provided on your NOI form. 

Section E. Discharge Information.

Indicate the appropriate monitoring period (Quarter 1, 2, 3, or 4) 

covered by the MDMR. “Alternative” monitoring periods can apply 

to facilities located in arid and semi-arid climates, or in areas 

subject to snow or prolonged freezing. To use alternative 

monitoring periods, you must provide a revised monitoring 

schedule here in the first monitoring report submitted and indicate 

for which alternative monitoring period you are reporting 

monitoring data. If using alternative monitoring periods, identify the 

first day of the monitoring period through the last day of the 

monitoring period for each of the four periods. The dates should be 

displayed as month (Mo) / day (Day). See Parts 6.1.6 and 6.1.7 of 

the permit for more information.

If you are submitting benchmark monitoring data, identify if your 

facility is required to collect benchmark samples for one or more 

hardness-dependent metals (i.e., cadmium, copper, lead, nickel, 

silver, and zinc). If you select “yes” to this question provide the 

hardness level of the receiving water (in mg/L)). If you select “no” 

to this question, you must identify if your facility discharges into any 

saltwater receiving waters.

Notice of Intent (NOI) for Stormwater Discharges 

Associated with Industrial Activity Under the NPDES Multi-Sector General Permit

NPDES Form Date (X/13) Form Approved OMB No. 2040-0004

F. Monitoring Information

For the reported monitoring event indicate whether the discharge 

was from a rainfall or snowmelt event. If you select “rainfall” then 

indicate the duration (in hours) of the rainfall event, rainfall total (in 

inches) for that rainfall event, and time (in days) since the previous 

measurable storm event in line items 2.a-c. For both rainfall and 

snowmelt monitoring, you must identify the date of collection for 

the monitoring event in column 3.i. of the table. If the discharge 

occurs during a period of both rainfall and snowmelt, check both 

the rainfall and snowmelt boxes and report the appropriate rainfall 

information in item 2.a-c. To report multiple monitoring events in 

the same reporting period, copy Page 3 of this Form and enter 

each monitoring event separately with data for all outfalls 

sampled. 

Identify all the outfalls from your facility that discharge stormwater. 

Each outfall must be assigned a unique 3-digit number (e.g., 

001),and should match the outfalls identified on your NOI form. 

If any outfalls are substantially identical, check the box in 3.b and 

identify the outfall that the outfall in 3.a is substantially identical to. In 

3.d – k, you only need to provide benchmark monitoring data for 

one of the outfalls. 

For any outfall for which there was no discharge during the 

monitoring period, check the box in 3.

In 3.d, identify the type of monitoring using the specified codes, in 

parentheses, below:

• (QBM) – Quarterly benchmark monitoring

• (ELG) – Annual effluent limitations guidelines monitoring; 

• (S/T) – State- or Tribal-specific monitoring; 

• (I) – Impaired waters monitoring; or

• (O) – Other monitoring as required by EPA.

In 3.e, enter each “parameter” (or “pollutant”) monitored. For 

QBM and ELG monitoring, use the same parameter name as in 

Part 8 of the permit.

In 3.f., enter a sample measurement value for each parameter 

analyzed and required to be reported. Enter “ND” (i.e., not 

detected) for any sample results below the method detection limit 

or “BQL” (i.e., below quantitation limit) for sample results above 

the detection limit but below the quantitation limit. 

In 3.g., enter the units for sample measurement values (i.e., “mg/L” 

for milligrams per liter) for each parameter analyzed and required 

to be reported. For monitoring results reported as ND or BQL this 

space will be left blank and the units will be reported in Column 

3.f.

3.h. must be completed for any monitoring results reported as ND 

or BQL in the “Quality or Concentration” column. For ND, report 

the laboratory detection level and units in this column. For BQL, 

report the laboratory quantitation limit and units in this column.

In 3.i. identify the sampling date for each parameter monitoring 

result reported on this form.

3.h. Exceedance due to natural background pollutant levels: 

Check box if following the first 4 quarters of benchmark monitoring 

(or sooner if the exceedance is triggered by less than 4 quarters of 

data) you have determined that the exceedance of the 

benchmark is attributable solely to the presence of that pollutant 

in the natural background for that outfall and any substantially 

identical outfalls. See Part 6.2.4.2 of the permit for more 

information. Attach supporting rationale for your determination to 

the submitted MDMR and reference attachment in Section E.4. 

In 3.j .check the box if after collection of 4 quarterly samples (or 

sooner if the exceedance is triggered by less than 4 quarters of 

data), the average of the 4 monitoring values for any parameter 

exceeds the benchmark and you have made the determination 

that no further pollutant reductions are technologically available 

and economically practicable and achievable in light of best 

industry practice to meet the technology-based effluent limits or 

are necessary to meet the water-quality-based effluent

Where violations of the permit requirements are reported, include 

a brief explanation to describe the cause and corrective actions 

taken, and reference each violation by date. Also, this section 

should include any additional comments such as are required 

when changing site status from inactive and unstaffed to active 

or vice versa. Attach additional pages if you need more space.

Attach additional copies of Section F as necessary to 

address all outfalls and parameters. 

Section G. Certification Information

Any facility whose primary activity is 

manufacturing coke oven products 

(e.g., coke, gases, tars) made in coke 

oven establishments should be 

regulated under Sector D, but may 

continue to be regulated under Sector 

F. Sector F requires sector-specific 

benchmark monitoring requirements 

for total aluminum and total zinc, 

Sector D does not require benchmark 

monitoring from these facilities.

Regulatory burden would be greater 

under Sector F.

List of Federal CERCLA Sites

Part 1.1.4.10 of the proposed MSGP has special requirements for discharges to a federal CERCLA site3. 

If your facility discharges to one of the federal CERCLA sites listed below, you are ineligible for coverage under this permit, unless you 

notify your applicable EPA Regional Office in advance and the EPA Office determines that you are eligible for permit coverage. In 

determining eligibility for coverage under Part 1.1.4.10, the EPA Regional Office may evaluate whether you have included 

appropriate controls and implementation procedures designed to ensure your discharge will not lead to recontamination of aquatic 

media at the CERCLA Site. If it is determined that your facility discharges to a CERCLA Site listed below after you have obtained 

coverage under this permit, you must contact your applicable EPA Regional Office to develop appropriate controls and/or

implementation procedures to ensure that your discharges will not lead to recontamination of aquatic media at the CERCLA Site. 

EPA Region 10

The CERCLA Sites and the receiving waters associated with these sites to which the requirements of Part 1.1.4.10 apply known at the 

time of permit issuance are listed in the table below. The areas where the permit applies are enumerated in Part C of the permit. For 

an up to date list and maps of CERCLA sites in Region 10, please check the Region 10 Superfund list viewable at 

http://yosemite.epa.gov/R10/cleanup.nsf/sites/cleanuplist. 

Operators who discharge / intend to discharge into the receiving waters listed must first contact the Regional office before submitting 

an NOI. Contact information is viewable at: http://yosemite.epa.gov/r10/water.nsf/Stormwater/industrial/. 

Similarly, if you have received notice from EPA that the facility to be covered under the MSGP is considered a potential source to a 

clean up site, you must first contact the Regional EPA office before submitting an NOI.

Because the boundaries of clean up sites are complicated, and sometimes change as new information becomes available, if it 

appears that your site may discharge storm water in the vicinity of a clean up site, it may be most expedient to check with the EPA 

Remedial Project Manager (RPM) to confirm whether this is indeed the case. Contact information can be found through 

(http://yosemite.epa.gov/r10/cleanup.nsf/sites/bh) 

The RPM can then access geo-references available for that site to pinpoint where the discharge is with respect to the official site.
