1.1.3 Allowable Non

- Stormwater Discharges

.

The following are the only non

- stormwater discharges authorized under this permit, provided that all discharges comply with the effluent limitations set forth in Part 2:

• Discharges from fire- fighting activities;

• Fire hydrant flushings;

• Potable water, including water line flushings;

• Uncontaminated condensate from air conditioners, coolers, and other compressors and from the outside storage of refrigerated gases or liquids;

• Irrigation drainage;

• Landscape watering provided all pesticides, herbicides, and fertilizers have been applied in accordance with the approved labeling;

• Pavement wash waters where no detergents or hazardous cleaning products are used (e.g., bleach, hydrofluoric acid, muriatic acid, sodium hydroxide, nonylphenol s ), and the

wash waters do not come into conta ct with oil and grease deposits or any other toxic or

hazardous materials (unless cleaned up using dry clean

- up methods) . You are prohibited from directing any authorized pavement wash waters directly into any surface water or storm drain inlet unless you have implemented appropriate control measures that meet

the non

- numeric effluent limits in Part 2.1.2. Where appropriate control measures are not in place, wash water runoff must first undergo treatment prior to discharge such as
filtration, detention, or settlement;

• Routine external building washdown / power washwater that does not use detergents or hazardous cleaning products, (such as those containing bleach, hydrofluoric acid, muriatic acid, sodium hydroxide

, nonylphenols );

• Uncontaminated ground water or spring water;

• Foundation or footing drains where flows are not contaminated with process materials;

• Incidental windblown mist from cooling towers that collects on rooftops or adjacent portions of your facility, but not intentional discharges from the co oling tower (e.g., “piped” cooling tower blowdown or drains) ; and

1 NSPS promulgated in 1974 were not removed via the 1982 regulation; therefore wastewaters generated by Part

423

- applicable sources that were New Sources under the 1974 regulations are subject to the 1974 NSPS.

Page 2 of 146Proposed 2013 MSGP

• Discharges from the spray down of lumber and wood product storage yards where no chemical additives are used in the spray

- down waters and no chemicals are applied to the wood during storage (applicable only to Sector A facilities provided the non

stormwater component of the discharge is in compliance with the non

- numeric effluent limits requirements in Part 2.1.2).

Also allowed are discharges of stormwater listed above in Parts 1.1.2 or authorized non

stormwater discharges in Part 1.1.3, commingled with a discharge authorized by a different NPDES permit and/or a discharge that does not require NPDES permit authorization. All other

non

- stormwater discharges requiring NPDES permit coverage e xcept those specifically listed in

Part 1.1.3 are not authorized by this permit. If non

- stormwater discharges requiring NPDES permit

coverage other than those specifically authorized in Part 1.1.3, including sector

- specific non

stormwater discharges that are listed in Part 8 (a non

- exclusive list provided to raise awareness of contaminants or sources of contaminants characteristic of certain sectors), will be discharged,

such non

- stormwater discharges are not covered by this permit or the permit shield provision of the CWA Section 402(k) and must be covered under another NPDES permit.

1.1.4 Limitations on Coverage.

Any discharges not expressly authorized under this permit are not within the scope of the pollutants authorized. Such discharges are not covered by this permit 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 (NOI) to be covered by the permit or by any ot her means (e.g., in the Storm w ater Pollution Prevention Plan (SWPPP) or during an inspection)

.

1.1.4.1 For Discharges Mixed with Non

- Stormwater. Stormwater discharges that are mixed with

non

- stormwater, other than those non

- stormwater discharges listed in Part 1.1.3, are not eligible for coverage under this permit.

1.1.4. 2 For Stormwater Discharges Associated with Construction Activity. Stormwater discharges associated with construction activity disturbing one acre or more, or that are part of a larger common plan of development or sale if the larger common plan will ultimately disturb one acre or more, are not eligible for coverage under this permit, unless in conjunction with mining activities or certain oil and gas extraction activities as specified in Sectors G, H, I, and J of this permit.

1.1.4 .3 For Discharges Currently or Previously Covered by Another Permit. Unless you have

r eceived written notification from EPA specifically allowing these discharges to be covered under this permit, you are not eligible for coverage under this permit for any of the following:

• Stormwater discharges associated with industrial activity that are currently covered under an individual NPDES permit or an alternative NPDES general permit;

• Discharges covered within five years prior to the effective date of this permit by an individual permit or alternative general permit where that permit established

s ite

- specific numeric water quality

- based limitations developed for the stormwater component of the discharge; or

• Discharges from facilities where any NPDES permit has been or is in the process of being denied, terminated, or revoked by EPA (this does not apply to the routine reissuance of permits every five years).

Page 3 of 146Proposed 2013 MSGP

1.1.4. 4 For Stormwater Discharges Subject to Effluent Limitations Guidelines. For discharges subject to stormwater effluent limitation guidelines under 40 CFR, Subchapter N, only

those stormw ater discharges identified in Table 1

- 1 are eligible for coverage under this permit.

1.1.4. 5 Endangered and Threatened Species and Critical Habitat Protection. Coverage under this permit is available only if your stormwater discharges, allowable non -stormwater discharges, and stormwater discharge

- related activities were the subject of an Endangered Species Act (ESA) consultation or an ESA Section 10 permit, or if your stormwater discharges, allowable non

- stormwater discharges, and stormwater discharge

- related activities are not likely t o adversely affect any species that are federally

- listed as endangered or threatened (“listed”) under the ESA and are not likely

t o adversely affect habitat that is federally

- designated as “critical habitat” under the

ESA. You must meet one of the criteria below, following the procedures in Appendix E:

Criterion A. No federally

- listed threatened or endangered species or their desi gnated 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 m ust 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

el igibility 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.

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 dischar ges 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

Page 4 of 146Proposed 2013 MSGP

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 o f 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 continu ed 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 adversel y 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 CF R §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

se ction 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 mu st 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.

You must comply with any applicable terms, conditions, or other requirements developed in the process of meeting the eligibility criteria in this section to remain eligible for coverage under this permit. Documentation of these requirements must be kept as part of your SWPPP (see Part 5.2.6.1).

1.1.4. 6 Historic Properties Preservation. Coverage under this permit is available only if you meet one of the eligibility criteria below, following the procedures in Appendix F:

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

convey ances) constructed or installed ; or

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) ; or

Page 5 of 146Proposed 2013 MSGP

Criterion C. Your 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, you 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
received a written conclusion that the subsurface stormwater controls w ill not

cause adverse effects o n 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 measur es required to mitigate or prevent adverse effects on historic properties ; or

Criterion D. Your subsurface stormwater controls have the potential to cause adverse e ffect s

on historic properties. You 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.

If you have been unable to reach agreement with a SHPO, THPO, or other tribal representative regarding appropriate measures to mitigate or prevent adverse effects, EPA may notify you of additional measures you must implement to be eligible for coverage under this permit.

1.1.4. 7 Eligibility f or New Dischargers: Based on Water Quality Standards

. If you are a new discharger (as defined in Appendix A), you are not eligible for coverage under this permit for discharges that EPA, prior to authorization under this permit, determines will not

meet a ny applicable water quality standard. Where such a determination is made prior to authorization, EPA may notify you that an individual permit application is necessary in

accordance with Part 1. 2.3 . However, EPA may authorize your coverage under this permit after you have included appropriate controls and implementation procedures designed to ensure your discharge meets water quality standards. In the absence of information demonstrating otherwise, EPA expects that compliance with the stormwater control requirements of this permit, including the requirements applicable to such discharges in Part 2, will meet applicable water quality standards.

1.1.4. 8 Eligibility for New Dischargers to Water

- Quality Impaired Waters. If you are a new discharger (as defined in Appendix A), you are not eligible for coverage under this permit to discharge to an “impaired water” (as defined in Appendix A) unless you do one of the following:

a. Prevent all exposure to stormwater of the pollutant(s) for which the waterbody is impaired, and retain documentation of procedures taken to prevent exposure onsite with your SWPPP.

b. Prior to submitting your NOI, provide to the appropriate EPA Regional Office technical information or other documentation to support your claim that the pollutant(s) for which the waterbody is impaired is not present at your site, and

retain such documenta tion with your SWPPP

.

c. Prior to submitting your NOI, provide to the appropriate EPA Regional Office information, either data or other technical documentation, to support a

Page 6 of 146Proposed 2013 MSGP

conclusion that the discharge is expected to meet applicable water quality

stand ards, and retain such information with your SWPPP. The information to be

submitted must be sufficient to demonstrate:

i. For discharges to waters without an EPA

- approved or established TMDL, that the discharge of the pollutant for which the water is impaired will meet in

stream water quality criteria at the point of discharge to the waterbody; or

ii. For discharges to waters with an applicable EPA

- approved or established TMDL, which specifically provides for a wasteload allocation to stormwater or determined that stormwater was not a source of the impairment, that there are sufficient remaining wasteload allocations in the TMDL to allow your discharge and that existing dischargers to the waterbody are subject to compliance schedules designed to bring the waterbody into attainment with water quality standards.

You are eligible under Part 1.1.4.8.c if you receive an affirmative determination from the Regional Office that your discharge will meet applicable water quality standards, in which case you must maintain such determination onsite with your SWPPP, or if the Regional Office fails to respond within 30 days of submission of data to the Regional Office.

Note: Your project will be considered to discharge to an impaired water if the first water of the U.S. to which you discharge is identified by a state, tribe, or EPA pursuant to Section 303(d) o f the CWA as not meeting an applicable water quality standard, or is

included in an EPA

- approved or established total maximum daily load (TMDL). For discharges that enter a storm sewer system prior to discharge, the first water of the U.S. to which you dis charge is the waterbody that receives the stormwater discharge from the storm sewer system.

1.1.4. 9 Eligibility for New Dischargers to Waters with High Water Quality.

For new dischargers to Tier 2 or Tier 2.5 waters: If you are a new discharger (as defined in Appendix A), you are eligible to discharge to a Tier 2 or Tier 2.5 water only if your discharge will not lower the water quality of the applicable water. See a list of Tier 2 and Tier 2.5 waters in Appendix L.

For new dischargers to Tier 3 waters: If you are a new discharger (as defined in Appendix A), you are not eligible for coverage under this permit for discharges to waters designated by a state or tribe as Tier 3 (outstanding natural resource waters) for antidegradation purposes under 40 CF R 131.13(a)(3). See a list of Tier 3 waters in Appendix L.

Note: Your project will be considered to discharge to a Tier 2, Tier 2.5, or Tier 3 water if the first water of the US to which you discharge is identified by a state, tribe, or EPA as a Tier 2, Tier 2.5, or Tier 3 water. For discharges that enter a storm sewer system prior to discharge, the first water of the US to which you discharge is the waterbody that receives the stormwater discharge from the storm sewer system.

1.1.4.10 For Discharges to a Federal CERCLA Site. If you discharge to a federal CERCLA Site as defined in Appendix A and referenced in Appendix P , you are ineligible for coverage under this permit, unless you notify your applicable EPA Regional Office in advance and

Page 7 of 146Proposed 2013 MSGP

the EPA Region al Office determine s that you are eligible for permit coverage pursuant to

Part 1.1.4.10. In determining eligibility for coverage under this Part, 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 S ite. If it is determined that your facility discharges to a CERCLA S ite referenced in Appendix P after you have obtained coverage under this permit, you must contact your applicable EPA Regional Office and develop appropriate controls and/or implementation procedures to ensure that your discharges will not lead to recontamination of aquatic media at the CERCLA Site.

For the purposes of this permit, a permittee discharges to a f ederal CERCLA Site if the discharge flows directly into the site through its own conveyance, or a through a conveyance owned by others, such as a municipal separate s torm sewer system.

EPA reserves the right to modify or revoke and reissue this permit under 40 CFR 122.62 and 63, in which case you will be notified of any relevant changes or procedures to which you may be subject.

1.2.3 Coverage Under Alternative Permits

.

EPA may require you to apply for and/or obtain authorization to discharge under an alternative permit, i.e., either an individual NPDES permit or an alternative NPDES general permit,

in accordance with 40 CFR 122.64 and 124.5. Any interested person may petition EPA to take action under this paragraph. If EPA requires you to apply for an alternative permit, the Agency will notify you in writing that a permit application is required. This notification will include a brief statement of the reasons for this decision and will contain alternative permit application requirements, including deadlines for completing your application.

1.2.3.1 Denial of Coverage for New or Previously Unpermitted Facilities

1.2.3.2 Loss of Authorization Under the 2013 MSGP for Existing Permitted Facilities. If your stormwater discharges are covered under this permit, you may receive a written notification that you must either apply for coverage under an individual NPDES permit or an alternative general NPDES permit, according to the provisions of Part 1.2.3. In addition to the reasons for the decision and alternative permit application deadlines, the

notice will include a statement that on the effective date of your alternative permit coverage, your coverage under the 2013 MSGP will terminate. EPA may grant additional time to submit the application if you request it. If you fail to submit an alternative permit application as required by EPA, then your authorization to discharge under the 2013 MSGP is terminated at the end of the day EPA required you to submit your alternative permit application. EPA may take appropriate enforcement action for any unpermitted discharge. When you become aut horized to discharge under an alternative permit, your coverage under the 2013 MSGP is terminated on the effective date your replacement permit coverage.

1.2.3.3 Operator Requesting Coverage Under an Alternative Permit. You may request to be

excluded fro m coverage under this general permit by applying for an individual permit. In such a case, you must submit an individual permit application in accordance with the requirements of 40 CFR 122.28(b)(3)(iii), with reasons supporting the request, to EPA at the applicable EPA Regional Office listed in Part 7. 9.1 of this permit. The request may be granted by issuance of an individual permit or authorization of coverage under an alternative general permit if your reasons are adequate to support the request. When

y ou are authorized to discharge under an alternative permit, your authorization to discharge under the 2013 MSGP is terminated on the effective date of the alternative permit.

Page 10 of 146Proposed 2013 MSGP

1.3 Terminating Coverage.

1.3.1 Submitting a Notice of Termination (NOT).

To terminate permit coverage, you must submit a complete and accurate NOT. Your authorization to discharge under this permit terminates at midnight of the day that you are notified that your complete NOT has been processed. If you submit a NOT without meeti ng one or more of the conditions identified in Part 1. 3 .3, then your NOT is not valid. You are responsible for meeting the terms of this permit until your authorization is terminated.

1.3.2 How t o Submit Your NOT.

See Part 7.2 for information on how to submit required information to EPA.

1.3.3 W hen to Submit Your NOT.

You must submit a NOT within 30 days after one or more of the following conditions have

been met:

• A new owner or operator has taken over responsibility for the facility ; or

• You have ceased operations at the facility, there are not or no longer will be discharges of stormwater associated with industrial activity from the facility, and you have already implemented necessary sediment and erosion controls as required by Part 2.1.2.5; or

• You are a Sector G, H, or J facility and you have met the applicable termination requirements; or

• You have obtained coverage under an individual or alternative general permit for all discharges required to be covered by an NPDES permit, unless EPA has required that you obtain such coverage under authority of Part 1. 2.3 , in which case coverage under this permit will terminate automatically.

1.4 Conditional Exclusion for No Exposure.

If you are covered by this permit, and become eligible for a “ no exposur e” exclusion from permitting under 40 CFR 122.26(g), you may file a No Exposure Certification. You are no longer required to have a permit upon submission of a complete and accurate no exposure certification to EPA. If you are no longer required to have pe rmit coverage because of a n o

e xposure exclusion and have submitted a No Exposure Certification form to EPA, you are not required to submit a NOT

. See Part 7.2 for information on how to submit required information to

EPA.

You must submit a No Exposure Cer tification to EPA once every five years.

1.5 Permit Compliance.

Any noncompliance with any of the requirements of this permit constitutes a violation of this permit, issued under the CWA . As detailed in Part 4 (Corrective Actions) of this permit, failure to take any required corrective actions constitutes an independent, additional violation of this permit, in addition to any original violation that triggered the need for corrective action. As such, any actions and time periods specified for remedying noncompliance do not absolve parties of the initial underlying noncompliance.

Page 11 of 146Proposed 2013 MSGP

W here corrective action is triggered by an event that does not itself constitute permit noncompliance, such as an exceedance of an applicable benchmark, there is no permit violation provided you take the required corrective action within the relevant deadlines

established in Part 4.2

.

2. Control Measures and Effluent Limits.

In the technology

- based limits included in Part s 2.1 and 8, the term “minimize” means
reduce and/ or eliminate to the extent achievable using control measures (including best management practices) that are technologically available and economically practicable and achievable in light of best industry practice.

2.1 Control Measures.

You must select, design, install, and implement control measures (including best management practices) to address the selection and design considerations in Part 2.1.1, meet

the non

- numeric effluent limits in Part 2.1.2, meet limits contained in applicable effluent limitations guidelines in Part 2.1.3, and meet the water quality

- based effluent limitations in Part

2.2. The selection, design, installation, and implementation of these control measures must be in accordance with good engineering practices and manufacturer’s specifications. Note that you may deviate from such manufacturer’s specifications where you provide justification for such deviation and include documentation of your rationale in the part of your SWPPP that describes your control measures, consistent with Part 5.2.4. If you find that your control measures are not achieving their intended effect of minimizing pollutant discharges, you must modify these control measures in accordance with the corrective action requirements set forth in Part 4. Regulated stormwater discharges from your facility include stormwater run- on that commingles

with stormwater discha rges associated with industrial activity at your facility.

Effluent limit requirements in Part 2.1.2 that do not involve the site

- specific selection of a control measure or are specific activity requirements (e.g., “Drain fluids from equipment and vehicles that will be decommissioned”) are marked with an asterisk (*). When documenting in your SWPPP in Part 5 how you will comply with the requirements marked with an asterisk, you have the option of including additional information or you may just “cut

- and

- pa ste” the effluent limits verbatim into your SWPPP without providing additional documentation (see Part 5.2.4).

2.1.1 Control Measure Selection and Design Considerations

.

You must consider the following when selecting and designing control measures:

• Preventing stormwater from coming into contact with polluting materials is generally more effective, and less costly, than trying to remove pollutants from
stormwater;

• Using control measures in combination is more effective than using control

measures in isolation for minimizing pollutants in your stormwater discharge;

• Assessing the type and quantity of pollutants, including their potential to impact receiving water quality, is critical to designing effective control measures that will

achieve the limits in this permit;

• Minimizing impervious areas at your facility and infiltrating runoff onsite (including bioretention cells, green roofs, and pervious pavement, among other approaches) can reduce runoff and improve ground water recharge and stream

base flow s in local streams, although care must be taken to avoid ground water
contamination;

Page 12 of 146Proposed 2013 MSGP

• Attenuating flow using open vegetated swales and natural depressions can

reduce in

- stream impacts of erosive flows;

• Conserving and/or restoring riparian buffers will help protect streams from stormwater runoff and improve water quality; and

• Using treatment interceptors (e.g., swirl separators and sand filters) may be appropriate in some instances to minimize the discharge of pollutants.

2.1.2 No n

- Numeric Technology

- Based Effluent Limits (BPT/BAT/BCT).

In addition to complying with the non

- numeric technology

- based effluent limits in Part 8, you must also:

2.1.2.1 Minimize Exposure. You must minimize the exposure of manufacturing, processing, and material storage areas (including loading and unloading, storage, disposal, cleaning, maintenance, and fueling operations) to rain, snow, snowmelt, and runoff by either locating these industrial materials and activities inside or protecting them with storm resistant coverings. In minimizing exposure, you must:

• Use grading, berming or curbing to prevent runoff of contaminated flows and

divert run- on away from these areas, unless infeasible;

• Locate materials, equipment, and activities so that potential leaks and spills are contained or able to be contained or diverted before discharge;

• Clean up spills and leaks promptly using dry methods (e.g., absorbents) to prevent the discharge of pollutants;

• Unless infeasible, store leaky vehicles and equipment indoors or, if stored

outd oors, use drip pans and absorbents;

• Use spill/overflow protection equipment;

• Perform all vehicle and/or equipment cleaning operations indoors, under cover, or in bermed areas that prevent runoff and run

- on and also that capture any

overspray;

• Drain fluids from equipment and vehicles that will be decommissioned or will remain unused for extended periods of time;* and

• Ensure that all washwater , with the exception of discharges from pavement wash water and routine building washdown described in Part 1.1.3, d rains to a sanitary sewer, sump, or other proper collection system (i.e., not the stormwater drainage system).*

The discharge of vehicle and equipment washwater, including tank cleaning operations, is not authorized by this permit. These wastewaters must be covered under a separate NPDES permit, discharged to a sanitary sewer in accordance with applicable industrial pretreatment requirements, or disposed of otherwise in accordance with applicable law.

Note: Industrial materials do not need to be enclosed or covered if stormwater runoff from affected areas does not discharge to receiving waters or if discharges are authorized under another NPDES permit.

2.1.2.2 Good Housekeeping. You must keep clean all exposed areas that are potential sources of pollut ants. You must perform good housekeeping measures

, including but not limited to, the following:

• Sweep or vacuum at regular intervals;

• Store materials in appropriate containers;

Page 13 of 146Proposed 2013 MSGP

• Identify and control all on

- site sources of dust to minimize stormwater contamination from the deposition of dust on areas exposed to precipitation ;

• Keep all dumpsters under cover or fit with a lid that must remain closed when not
in use;* and

• Ensure that waste, garbage, and floatable debris are not discharged to receiving

wa ters by keeping exposed areas free of such materials or by intercepting them before they are discharged.

Plastic Materials Requirements: Facilities that handle pre

- production plastic pellets are required to implement best management practices to eliminate discharges of plastic in stormwater. Examples of plastic material required to be addressed as stormwater pollutants include plastic resin pellets, powders, flakes, additives, regrind, scrap, waste and recycling.

2.1.2.3 Maintenance. You must maintain all contro l measures that are used to achieve the effluent limits required by this permit in effective operating condition, as well as all industrial equipment and systems to help prevent discharges of pollutants from them. This

includes:

• Performing inspections and preventive maintenance of stormwater drainage, source controls, treatment systems, and plant equipment and systems that could

fail and result in contamination of stormwater.

• Diligently maintaining nonstructural control measures (e.g., keep spill response supplies available, personnel appropriately trained).

• Inspecting and maintaining bag houses quarterly to prevent the escape of dust from the system and immediately removing any accumulated dust at the base of the exterior bag house.*

• Cleaning catch basins when the depth of debris reaches two

- thirds (2/3) of the sump depth and keeping the debris surface at least six inches below the outlet pipe.*

If you find that your control measures need to be replaced or repaired, you must immediately take all reasonable steps to prevent or minimize the discharge of pollutants until a permanent solution is installed and made operational, including cleaning up any

c ontaminated surfaces so that the material will not discharge during subsequent storm

events.

Note: In this context, the term “immediately” requires you to, on the same day you identify that a control measure needs to be replaced or repaired , take all re asonable steps to minimize or prevent the discharge of pollutants until a permanent solution is installed and made operational. However, if a problem is identified at a time in the work day when it is too late to take action, the initiation of action must begin on the following work day.

2.1.2.4 Spill Prevention and Response. You must minimize the potential for leaks, spills and other releases that may be exposed to stormwater and develop plans for effective response to such spills if or when they occur. You must conduct spill prevention and response measures, including but not limited to, the following:

• Plainly label containers (e.g., “Used Oil,” “Spent Solvents,” “Fertilizers and

Pesticides” ) that could be susceptible to spillage or leakage to encourage proper handling and facilitate rapid response if spills or leaks occur;*

Page 14 of 146Proposed 2013 MSGP

• Implement procedures for material storage and handling, including the use of secondary containment and barriers between material storage and traffic areas

, or a similarly effective means designed to prevent the discharge of pollutants

from these areas ;

• Develop training on the procedures for expeditiously stopping, containing, and cleaning up leaks, spills, and other rele ases. As appropriate, execute such procedures as soon as possible.

• Keep spill kits on

- site, located near areas where spills may occur; and

• Notify appropriate facility personnel, emergency response agencies, and regulatory agencies when a leak, spill, or o ther release occurs.

Where a leak, spill or other release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117, or 40 CFR Part 302, occurs during a 24- hour period, you must notify the National Response Center (NRC) at (800) 424

- 8802 or, in the Washington, DC, metropolitan area, call (202) 267- 2675 in accordance with the requirements of 40 CFR Part 110, 40 CFR Part 117, and 40 CFR Part 302 as soon as you have knowledge of the discharge. State or local requirements may necessitate reporting spills or discharges to local emergency response, public health, or drinking water supply agencies. Contact information must be in locations that are readily accessible and available.

2.1.2.5 Erosion and Sediment Controls. You must minimize erosion by stabilizing exposed soils at your facility and placing flow velocity dissipation devices at discharge locations. You

must also use structural and non -structural control m easures to prevent the discharge of

sediment. If you use polymers and/or other chemical treatments as part of your controls, you must identify the polymers and/or chemicals used and the purpose. There are many resources available to help you select appropriate BMPs for erosion and sediment control, including EPA’s Stormwater Discharges from Construction Activities website at: www.epa.gov/npdes/stormwater/construction

.

2.1.2.6 Management of R unoff. You must divert, infiltrate, reuse, contain, or otherwise reduce stormwater runoff, to minimize pollutants in your discharges. In selecting, designing, installing, and implementing appropriate control measures, you are encouraged to

consult with EPA’s internet

- based resources relating to runoff management, including the

sector

- specific Industrial Stormwater Fact Sheet Series

, ( www.epa.gov/npdes/stormwater/msgp ), National Menu of Stormwater BMPs ( www.epa.gov/npdes/stormwater/menuofbmps ), and National Management Measures to Control Nonpoint Source Pollution from Urban Areas ( www.epa.gov/owow/nps/urbanmm/index.html ), and any similar state or tribal

resources.

2.1.2.7 Salt Storage Piles or Piles Containing Salt

. You must enclose or cover storage piles of salt, or piles containing salt, used for deicing or other commercial or industrial purposes, including maintenance of paved surfaces. You must implement appropriate measures (e.g., good housekeeping, diversions, containment) to minimize exposure resulting from adding to or removing materials from the pile. Piles do not need to be enclosed or covered if stormwater runoff from the piles is not discharged or if discharges from the piles are authorized under another NPDES permit.

2.1.2.8 Employee Training. You must train all employees who work in areas where industrial materials or activities are exposed to stormwater, or who are responsible for implementing activities necessary to meet the conditions of this permit (e.g., inspectors,

Page 15 of 146Proposed 2013 MSGP

maintenance personnel), including all members of your Pollution Prevention Team. You

must ensure the following personnel understand the requirements of this permit and their specific responsibilities with respect to those requirements:

• Personnel who are responsible for the design, installation, maintenance, and/or repair of controls (including pollution prevention measures);

• Personnel responsible for the storage and handling of chemicals and materials

that could become contaminants in stormwater discharges;

• Personnel who are responsible for conducting and documenting monitoring and inspections as required in Parts 3 and 6; and

• Personnel who are responsible for taking and documenting corrective actions as required in Part 4.

P ersonnel must be trained in at least the following if related to the scope of their job duties (e.g., only personnel responsible for conducting inspections need to understand how to conduct inspections):

• An overview of what is in the SWPPP;

• Spill response procedures, good housekeeping, maintenance requirements, and material management practices;

• The location of all controls on the site required by this permit, and how they are to
be maintained;

• The proper procedures to follow with respect to the permit’s pollution prevention requirements; and

• When and how to conduct inspections, record applicable findings, and take

corrective actions.

2.1.2.9 Non

- Stormwater Discharges. If non

- stormwater discharges requiring NPDES permit

coverage other than those specifically authorized in Part 1.1.3 will be discharged, such

non

- stormwater discharges are not covered by this permit or the permit shield provision of the CWA Section 402(k) and must be covered under another NPDES permit.

2.1.2.10 Dust Generation and Vehicle Tracking of Industrial Materials. You must minimize generation of dust and off

- site tracking of raw, final, or waste materials.

2.1.3 Numeric Effluent Limitations Based on Effluent Limitations Guidelines

.

If you are in an industrial category subject to one of the effluent limitations guidelines

identified in Table 6

- 1 (see Part 6.2.2.1), you must meet the effluent limits referenced in Table 2 -1

below:

2.2 Water Quality

- Based Effluent Limitations.

2.2.1 Water Quality Standards

.

Your discharge must be controlled as necessary to meet applicable water quality

standards.

EPA expects that compliance with the conditions in this permit will control discharges as necessary to meet applicable water quality standards. If at any time you become aware, or EPA determines, that your discharge does not meet applicable water quality standards, you must take corrective action as required in Part 4.1 and document the corr ective actions as required in Part 4.3. You must also comply with any additional requirements that your state or tribe requires
in Part 9.

EPA may also impose additional water quality

- based limitations on a site

- specific basis, or require you to obtain coverage under an individual permit, if information in your NOI, require d reports, or from other sources indicates that your discharges are not controlled as necessary to

meet applicable water quality standards

. You must implement all controls necessary to comply with a wasteload allocation in an EPA established or approved TMDL.

2.2.2 Discharges to Water Quality

- Impaired Waters.

Note: Your project wil l be considered to discharge to an impaired water if the first water of the U.S. to which you discharge is identified by a state, tribe, or EPA pursuant to Section 303(d) of the CWA as not meeting an applicable water quality standard, or is

included in an EPA

- approved or established total maximum daily load (TMDL). For discharges that enter a storm sewer system prior to discharge, the first water of the U.S. to which you discharge is the waterbody that receives the stormwater discharge from the

stor m sewer system.

2.2.2.1 Existing Discharge to an Impaired Water with an EPA

- Approved or Established TMDL. If you discharge to an impaired water with an EPA approved or established TMDL, EPA will inform you if any additional limits or controls are necessa ry for your discharge to be consistent with the assumptions of any available wasteload allocation in the TMDL, or if coverage under an individual permit is necessary in accordance with Part 1.5.1.

Page 17 of 146Proposed 2013 MSGP

2.2.2.2 Existing Discharge to an Impaired Water without an EPA

- Approved or Established TMDL. If you discharge to an impaired water without an EPA approved or established TMDL, you are still required to comply with Part 2.2.1, and you must comply with the monitoring requirements of Part 6.2.4. No te that this provision also applies to situations where EPA determines that your discharge is not controlled as necessary to meet water quality standards in a downstream water segment, even if your discharge is to a receiving water that is not specifically identified on a Section 303(d) list.

2.2.2.3 New Discharge to an Impaired Water. If your authorization to discharge under this permit relied on Part 1.1.4.8 for a new discharge to an impaired water, you must implement and maintain any control measures or conditions on your site that enabled you to become eligible under Part 1.1.4.8, and modify such measures or conditions as necessary pursuant to any Part 4 corrective actions. You are also required to comply with Part 2.2.1 and the monitoring requiremen ts of Parts 6.2.4.

2.2.3 T ier 2 Antidegradation Requirements for New or Increased Dischargers

.

If you are a new discharger, or an existing discharger required to notify EPA of an increased discharge consistent with Part 7.7 (i.e., a “planned changes” re port), and you discharge directly to waters designated by a state or tribe as Tier 2 or Tier 2.5 for antidegradation

purposes und er 40 CFR 131.12(a), in the absence of information demonstrating otherwise, EPA expects that compliance with the stormwater control requirements of this permit will result in discharges that will not lower the water quality of the applicable water. See list of Tier 2 and 2.5 waters in Appendix L. However, EPA may notify you that additional analyses, control measures, or other perm it conditions are necessary to comply with the applicable antidegradation requirements, or notify you that an individual permit application is necessary in accordance with

Part 2.2. 1.

2.3 Requirements Relating to Endangered Species and Historic Properti es

.

If your eligibility under either Part 1.1.4. 5 or Part 1.1.4.6 was made possible through your, or another operator’s, agreement to include certain measures or prerequisite actions, or implement certain terms and conditions, you must comply with all su ch agreed

- upon requirements to maintain eligibility under the MSGP.

3. Inspections

.

3.1 Ro utine Facility Inspections.

During normal facility operating hours you must conduct inspections of areas of the facility covered by the requirements in this permit, including the following:

• Areas where industrial materials or activities are exposed to stormwater.

• Areas identified in the SWPPP and those that are potential pollutant sources (see Part 5.2.3).

• Areas where spills and leaks have occurred in the past 3 years.

• Discharge points.

• Control measures used to comply with the effluent limits contained in this permit.

Inspections must be conducted at least quarterly (i.e., once each calendar quarter), or in some instances more frequently (e.g., monthly), as appropriate. Increased frequency may be appropriate for some types of equipment, processes and stormwater control measures, or areas

Page 18 of 146Proposed 2013 MSGP

of the facility with significant activities and materials exposed to stormwater. At least one of your routine inspections must be conducted during a period when a stormwater discharge is occurring.

Inspections must be performed by qualified personnel (as defined in Appendix A) with at least one member of your stormwater pollution prevention team participating. Inspectors must consider the results of visual and analytical monitoring (if any) for the past year when planning and conducting inspections.

During the inspection you must examine or look out for the following:

• Industrial materials, residue or trash that may h ave or could come into contact with

stormwater.

• Leaks or spills from industrial equipment, drums, tanks and other containers.

• Offsite tracking of industrial or waste materials, or sediment where vehicles enter or exit

the site.

• Tracking or blowing of raw, final or waste materials from areas of no exposure to exposed

areas.

• Control measures needing replacement, maintenance or repair.

During an inspection occurring during a stormwater discharge, control measures implemented to comply with effluent limits must be observed to ensure they are functioning correctly. Discharge points, as defined in Appendix A, must also be observed during this inspection. If such discharge locations are inaccessible, nearby downstream locations must be inspected.

3.1.1 Ex ceptio ns to Routine Facility Inspections for Inactive and Unstaffed Sites

.

The requirement to conduct facility inspections on a routine basis does not apply at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. Such a facility is only required to conduct an annual site inspection in

accordance with Part 3.1. To invoke this exception, you must indicate your facility is inactive and unstaffed on your NOI. If you are already covered under the permit and your facility has changed from active to inactive and unstaffed, you must modify your NOI. You must also maintain a statement in your SWPPP pursuant to Part 5.2.5.2 indicating that the site is inactive

and unstaffed , and that there are no industrial materials or activities exposed to precipitation, in accordance with the substantive requirements in 40 CFR 122.26(g)(4)(iii). The statement must be sig ned and certified in accordance with Appendix B, Subsection 11. If circumstances change and industrial materials or activities become exposed to stormwater or your facility becomes active and/or staffed, this exception no longer applies and you must immedi ately resume routine facility inspections. If you are not qualified for this exception at the time you are authorized under this permit, but during the permit term you become qualified because your facility is inactive and unstaffed, and there are no industrial materials or activities that are exposed to stormwater, you must include the same signed and certified statement as above and retain it with your records pursuant to Part 5.5.

Inactive and unstaffed facilities covered under Sectors G (Metal Mining), H (Coal Mines and Coal Mining

- Related Facilities), and J (Non

- Metallic Mineral Mining and Dressing), are not required to meet the “no industrial materials or activities exposed to stormwater” standard to be eligible for this exception from routine inspections, consistent with the requirements established in
Parts 8.G.8.4, 8.H.8.1, and 8.J.8.1.

Page 19 of 146Proposed 2013 MSGP

3.1 .2 Routine Facility Inspection Documentation.

You must document the findings of your facility inspections and maintain this report with your SWPPP as required i n Part 5.5. Do not submit your routine facility inspection report to EPA, unless specifically requested to do so. However, you must summarize your findings in the annual report per Part 7.5. Document all findings, including but not limited to, the following information:

• The inspection date and time;

• The name(s) and signature(s) of the inspector(s);

• Weather information;

• All observations relating to the implementation of control measures at the facility, including:

o A descri ption of any discharges occurring at the time of the inspection;

o Any previously unidentified discharges and/or pollutants from the site;

o Any evidence of, or the potential for, pollutants entering the drainage system;

o Observations regarding the physical condition of and around all outfalls including any flow dissipation devices, and evidence of pollutants in discharges and/or the receiving water;

o Any control measures needing maintenance, repairs, or replacement;

• Any additional control measures needed to comply with the permit requirements; and

• Any incidents of noncompliance observed

.

Any corrective action required as a res ult of a routine facility inspection must be performed consistent with Part 4 of this permit.

If you performed a discharge visual assessment required in Part 3. 2 during your facility inspection, you may include the results of the assessment with the report required in Part 3 .1.2, as long as all components of both types of inspections are included in the report.

3. 2 Quarterly Visual Assessment of Stormwater Discharges.

3. 2 .1 Quarterly Visual Assessment Procedures.

Once each quarter for the entire permit term, you must collect a stormwater sample from each outfall (except as noted in Part 3. 2. 3) and conduct a visual assessment of each of these samples. These samples are not required to be collected consistent with 40 CFR Part 136 procedures but should be collected in such a manner that the samples are representative of the stormwater discharge. Guidance on monitoring is available at www.epa.gov/npdes/stormwater/msgp

.

The visual assessment must be made:

• Of a sample in a clean, clear glass, or plastic container, and examined in a well

- lit

area;

• On samples collected within the first 30 minutes of an actual discharge from a

storm event. If it is not possible to collect the sample within the first 30 minutes of discharge, the sample must be collected as soon as practicable after the first 30 minutes and you must document why it was not possible to take samples within the first 30 minutes. In the case of snowmelt, samples must be taken during a period with a measurable discharge from your site; and

• For storm events, on discharges that occur at least 72 hours (3 days) from the previous discharge. The 72

- hour (3

- day) storm interval does not apply if you

Page 20 of 146Proposed 2013 MSGP

document that less than a 72

- hour (3

- day) interval is representative for local storm events during the sampling period.

You must visually inspe ct or observe the sample for the following water quality

characteristics:

• Color;

• Odor;

• Clarity ( diminished );

• Floating solids;

• Settled solids;

• Suspended solids;

• Foam;

• Oil sheen; and

• Other obvious indicators of stormwater pollution.

Whenever the visual assessment shows obvious signs of stormwater pollution, you must initiate the corrective action procedures in Part 4.

3. 2 .2 Quarterly Visual Assessment Documentation.

You must document the results of your visual assessments and maintain this

documentati on onsite with your SWPPP as required in Part 5.5. You are not required to submit your visual assessment findings to EPA, unless specifically requested to do so. Your
documentation of the visual assessment must include , but not be limited to :

• Sample loca tion(s);

• Sample collection date and time, and visual assessment date and time for each sample;

• Personnel collecting the sample and performing visual assessment, and their signatures;

• Nature of the discharge (i.e., runoff or snowmelt);

• Results of observatio ns of the stormwater discharge;

• Probable sources of any observed stormwater contamination; and

• If applicable, why it was not possible to take samples within the first 30 minutes.

Any corrective action required as a result of a quarterly visual assessment must be performed consistent with Part 4 of this permit.

3. 2 .3 Exceptions to Quarterly Visual Assessments.

Adverse Weather Conditions : When adverse weather conditions prevent the collection of samples during the quarter, you must take a substitute sample during the next qualifying storm event. Documentation of the rationale for no visual assessment for the quarter must be included with your SWPPP records as described in Part 5.5. Adverse conditions are those that are dangerous or create inaccessibility for personnel, such as local flooding, high winds, or electrical storms, or situations that otherwise make sampling impractical, such as extended frozen conditions.

Climates with Irregular Stormwater Runoff : If your facility is located in an area where limited rainfall occurs during many parts of the year (e.g., arid or semi

- arid climate) or in an area where freezing conditions exist tha t prevent runoff from occurring for extended periods, then your samples for the quarterly visual assessments may be distributed during seasons when precipitation runoff occurs.

Page 21 of 146Proposed 2013 MSGP

Areas Subject to Snow : In areas subject to snow, at least one quarterly visu al assessment must capture snowmelt discharge, as described in Part 6.1.3, taking into account the exception described above for climates with irregular stormwater runoff.

Inactive and U nstaffed S ites : The requirement for a quarterly visual assessment d oes not apply at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. To invoke this exception, you must maintain a statement in your SWPPP as required in Part 5.2.5.2 indicating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to precipitation, in accordance with the substantive requirements in 40 CFR 122.26(g)(4)(iii). The statement must be signed and certified in accordance with Appendix B, Subsection 11. If circumstances change and industrial materials or activities become exposed to stormwater or your facility becomes active and/or staffed, this exception no longer applies and you must immediately resume quarterly visual asse ssments. If you are not qualified for this exception at the time you are authorized under this permit, but during the permit term you become qualified because your facility is inactive and unstaffed,

and there are no industrial materials or activities tha t are exposed to stormwater, then you must include the same signed and certified statement as above and retain it with your records pursuant to Part 5.5.

Inactive and unstaffed facilities covered under Sectors G (Metal Mining), H (Coal Mines and Coal Mining

- Related Facilities), and J (Non

- Metallic Mineral Mining and Dressing), are not required to meet the “no industrial materials or activities exposed to stormwater” standard to be eligible for this exception from quarterly visual assessment, consistent with the requirements established in Parts 8.G.8.4, 8.H.8.1, and 8.J.8.1.

Substantially Identical O utfalls : If your facility has two or more outfalls that you believe discharge substantially identical effluents, as documented in Part 5.2.5. 3 , you may conduct quarterly visual assessments of the discharge at just one of the outfalls and report that the results also apply to the substantially identical outfall(s) provided that you perform visual assessments on a rotating basis of each substantially identical outfall throughout the period of your coverage under this permit.

If stormwater contamination is identified through visual assessment performed at a substantially identical outfall, you must assess and modify your control measures as

app ropriate for each outfall represented by the monitored outfall.

4. Corrective Actions

.

4.1 Conditions Requiring SWPPP Review and Revision to Eliminate Problems

.

When any of the following conditions occur or are detected during an inspection, monitoring or other means, or the EPA, or local, state or tribal entity informs you that any of the following conditions has occurred, you must review your SWPPP (e.g., sources of pollution, spill and leak procedures, non

- stormwater discharges, selection, design, installation and implementation of your control measures) to determine if and where revisions may need to be made to eliminate the condition, prevent its reoccurrence, and ensure that effluent limits are

met:

• An unauthorized release or discharge (e.g., spill, leak, or discharge of non

- stormwater not authorized by this or another NPDES permit) occurs at your facility.

Page 22 of 146Proposed 2013 MSGP

• A discharge violates a numeric effluent limit.

• Your control measures are not stringent enough for the discharge to meet applicable water quality standards or the non

- numeric effluent limits in this permit.

• A required control measure was never installed, was installed incorrectly, or not in

accordance with Parts 2 and/or 8 , or is not being properly operated or maintained

.

• Visual assessments indicate obvious signs of stormwater pollution (e.g., color, odor, floating solids, settled solids, suspended solids, foam)

.

• The average of four quarterly sampling results exceeds an applicable benchmark (see Part 6.2.1.2) . If less than four benchmark samples have been taken, but the results are such that an exceedance of the four quarter average is mathematically certain (i.e., if the sum of quarterly sample results to date is more than four times the benchmark level) this is considered a benchmark exceedance, triggering this review.

• Construction or a change in design, operation, or maintenance at your facility that significantly changes the nature of pollutants discharged in stormwater from your facility, or significantly increases the quantity of pollutants discharged.

4.2 Corrective Actions and Deadlines

.

4.2.1 Immediate Actions

.

In all circumstances, you must immediately take all reasonable steps necessary to minimize or prevent the discharge of pollutants until a permanent solution is installed and made operational, including cleaning up any contaminated surfaces so that the material will not discharge in subsequent storm events.

Note: In this context, the term “immediately” requires you to, on the same day a condition requiring corrective action is found, take all reasonable steps to minimize or prevent the discharge of pollutants until a permanent solution is installed and made operational. However, if a probl em is identified at a time in the work day when it is too late to initiate corrective action, the initiation of corrective action must begin on the following work day.

4.2.2 Subsequent Actions

.

If you determine that additional changes are necessary beyond those implemented pursuant to Part 4.2.1, you must install a new or modified control and make it operational, or complete the repair, before the next storm event if possible, and within 14 calen dar days from the time of discovery. If it is infeasible to complete the installation or repair within 14 calendar days, you must document why it is infeasible to complete the installation or repair within the 14

- day timeframe . You must also identify your schedule for completing the work, which must be

done as soon as practicable after the 14

- day timeframe but no longer than 45 days after discovery.

Where your corrective actions result in changes to any of the controls or procedures documented in your SWPPP, you must modify your SWPPP accordingly within 14 calendar days of completing corrective action work.

These time intervals are not grace periods, but are schedules considered reasonable for documenting your findings and for making repairs and improvements. They are included in this permit to ensure that the conditions prompting the need for these repairs and improvements are not allowed to persist indefinitely.

Page 23 of 146Proposed 2013 MSGP

4.3 Corrective Action Documentation

.

You must docu ment the existence of any of the conditions listed in Part 4.1 within 24 hours of becoming aware of such condition. You are not required to submit your corrective action documentation to EPA, unless specifically requested to do so. Include the following

in formation in the documentation :

• Identification and description of the condition triggering the need for corrective action

review . For any spills or leaks, include the following information: a description of the incident including material, date/time, amount, location, and reason for spill , and any leaks, spills or other releases that resulted in discharges of pollutants to waters of U.S., through stormwater or otherwise;

• Date the condition was identified; and

• A discussion of whether the triggering condition requires corrective action. For any spills or leaks, include response actions, the date/time clean

- up completed, notifications
made, and staff involved. Also include any measures taken to prevent the reoccurrence of such releases (see Part 2.1.2.4).

You must also document the corrective actions taken that occurred as a result of the conditions listed in Part 4.1, within 14 days from the time of discovery of any of those conditions.

Provide the dates when eac h corrective action was initiated and completed (or is expected to be completed). If applicable, document why it is infeasible to complete necessary installations or repairs within the 14

- day timeframe and document your schedule for installing the controls and making them operational as soon as practicable after the 14

- day timeframe.

4.4 Effect of Corrective Action

.

If the event triggering the review is a permit violation (e.g., non

- compliance with an effluent limit), correcting it does not remove the original violation. Additionally, failing to take corrective action in accordance with this section is an additional permit violation. EPA will consider the appropriateness and promptness of corrective action in determining enforcement responses to permit violations.

4.5 Substantially Identical Outfalls

.

If the event triggering corrective action is linked to an outfall that represents other substantially identical outfalls, your review must assess the need for corrective action for each outfall represented by the outfall that triggered the review. Any necessary changes to control

measures that affect these other outfalls must also be made before the next storm event if possible, or as soon as practicable following that storm event. Any corrective actions mus t be
conducted within the timeframes set forth in Part 4 .2

.

5. Storm water Pollution Prevention Plan (SWPPP).

You must prepare a SWPPP for your facility before submitting your NOI for permit coverage. If you prepared a SWPPP for coverage under a previous version of this NPDES permit, you must review and update the SWPPP to implement all provisions of this permit prior to submitting your NOI. The SWPPP does not contain effluent limitations; the limitations are contained in Parts 2, 8, and 9 of the permit. The SWPPP is intended to document the selection, design, and installation of control measures. As distinct from the SWPPP, the additional documentation requirements (see Part 5.5) are intended to document the implementation

Page 24 of 146Proposed 2013 MSGP

(including inspection, maintenance, monitoring, and corrective action) of the permit requirements.

Note that a ny 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 via the SWPPP or by any other means (e.g., during an inspection).

5.1 Person(s) Responsible for SWPPP Preparation

.

The SWPPP shall be prepared in accordance with good engineering practices and to industry standards. The SWPPP may be developed by either a person on your staff or a third party you h ire, and it shall be certified in accordance with the signature requirements in Part

5.2.7 . If EPA concludes that the SWPPP is not in substantial compliance with Part 5.2 of this permit, EPA may require the SWPPP to be reviewed, amended as necessary, and certi fied by a Professional Engineer, or for Sector G, H or J, by a Professional Geologist, with the education and experience necessary to prepare an adequate SWPPP.

5.2 Co ntents of Your SWPPP.

For coverage under this permit, your SWPPP must contain all of the following elements:

• Stormwater pollution prevention team (see Part 5.2.1);

• Site description (see Part 5.2.2);

• Summary of potential pollutant sources (see Part 5.2.3);

• Description of control measures (see Part 5.2.4);

• Schedules and procedures (see Part 5.2.5);

• Documentation to support eligibility considerations under other federal laws (see Part 5.2.6); and

• Signature requirements (see Part 5.2.7).

Where your SWPPP refers to procedures in other facility documents, suc h as a Spill Prevention, Control and Countermeasure (SPCC) Plan or an Environmental Management System (EMS), copies of the relevant portions of those documents must be kept with your SWPPP.

5.2.1 Stormwater Pollution Prevention Team.

You must identify the staff members (by name or title) that comprise the facility’s stormwater pollution prevention team as well as their individual responsibilities. Your stormwater pollution prevention team is responsible for overseeing development of the SWPPP, any later modifications to it, and for compliance with the requirements in this permit. Each member of the stormwater pollution prevention team must have ready access to either an electronic or paper copy of applicable portions of this permit, the most updated copy of your SWPPP, other relevant documents or information that must be kept with the SWPPP.

5.2.2 Site Description.

Your SWPPP must include the following:

• Activities at the Facility. Provide a d escription of the nature of the industrial activities at your facility.

Page 25 of 146Proposed 2013 MSGP

• General location map . Provide a general location map (e.g., U.S. Geological Survey (USGS) quadrangle map) with enough detail to identify the location of your facility and all receiving waters for your stormwater discharges.

Page 26 of 146Proposed 2013 MSGP

5.2.3 Summary of Potential Pollutant Sources.

You must document areas at your facility where industrial materials or activities are exposed to stormwater or from which allowable non

- stormwater discharges may be released

. Industrial materials or activitie s include, but are not limited to: material handling equipment or activities; industrial machinery; raw materials; industrial production and processes; and intermediate products, by

- products, final products, and waste products. Material handling

activities include, but are not limited to: the storage, loading and unloading, transportation, disposal, or conveyance of any raw material, intermediate product, final product or waste product. For structures located in areas of industrial activity, you must be aware that the structures themselves are potentia l sources of pollutants. This could occur, for example, when metals such as aluminum or copper are leached from the structures as a result of acid rain.

For each area identified, the description must include:

5.2.3.1 Activities in the Area. A list of the industrial activities exposed to stormwater (e.g., material storage; equipment fueling, maintenance, and cleaning; cutting steel beams).

5.2.3.2 Pollutants. A list of the pollutant(s) or pollutant constituents (e.g., crankcase oil, zinc,

s ulfuric acid, and cleaning solvents) associated with each identified activity, which could be exposed to rainfall or snowmelt and could be discharged from your facility. The pollutant list must include all significant materials that have been handled, trea ted, stored, or disposed, and that have been exposed to stormwater in the three years prior to the date you prepare or amend your SWPPP.

5.2.3.3 Spills and Leaks. You must document where potential spills and leaks could occur that could contribute pollutants to stormwater discharges, and the corresponding outfall(s) that would be affected by such spills and leaks. You must document all significant spills and leaks of oil or toxic or hazardous pollutants that actually occurred at exposed areas,

or that dra ined to a stormwater conveyance, in the three years prior to the date you prepare or amend your SWPPP.

Note: Significant spills and leaks include, but are not limited to, releases of oil or hazardous substances in excess of quantities that are reportabl e under CWA Section 311 (see 40 CFR 110.6 and 40 CFR 117.21) or Section 102 of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), 42 USC §9602. This permit does not relieve you of the reporting requirements of 40 CFR 110, 40 CFR 117, and 40 CFR 302 relating to spills or other releases of oils or hazardous substances.

5.2.3.4 Non

- Stormwater Discharges. You must document that you have evaluated for the presence of non -stormwater discharges. If non

- stormwater discharges requiring NPDES permit coverage other than those specifically authorized in Part 1.1.3 will be discharged,

consistent with Part 6.2.1.2.

• Documentation to support any determination that pollutan ts of concern are not expected to be present above natural background levels if you discharge directly to impaired waters, and that such pollutants were not detected in your discharge or were solely attributable to natural background sources (see Part 6.2. 1 .2); and

• Documentation to support your claim that your facility has changed its status from active to inactive and unstaffed with respect to the requirements to conduct routine facility inspections (see Part 3.1), quarterly visual assessments (see Part 3. 2 ), and/or benchmark monitoring (see Part 6.2.1.3).

6. Monitoring.

You must collect and analyze stormwater samples and document monitoring activities consistent with the procedures described in Part 6 and Appendix B, Subsections 10 – 12, and any
additio nal sector

- specific or state/tribal

- specific requirements in Parts 8 and 9, respectively. Refer to Part 7 for reporting and recordkeeping requirements.

6.1 Monitoring Procedures

.

6.1.1 Monitored Outfalls.

Applicable monitoring requirements apply to each outfall authorized by this permit, except as otherwise exempt from monitoring as a “substantially identical outfall.” If your facility has two or more outfalls that you believe discharge substantially identical effluents, based on the similarities of the general industrial activities and control measures, exposed materials that may significantly contribute pollutants to stormwater, and runoff coefficients of their drainage areas, you may monitor the effluent of just one of the outfalls and report that the results also apply to the substantially identical outfall(s). As required in Part 5.2.5. 3 , your SWPPP must identify each outfall authorized by this permit and describe the rationale for any substantially identical outfall determinations. The allowance for monitoring only one of the substantially identical outfalls is not applicable to any outfalls with numeric effluent limitations. You are required to monitor each outfall covered by a numeric effluent limit as identified in Part 6.2.2.

Page 32 of 146Proposed 2013 MSGP

6.1.2 Commingled Discharges.

If discharges authorized by this permit commingle with discharges not authorized under this permit, any required sampling of the authorized discharges must be performed at a point before they mix with other waste streams, to the extent practi cable.

6.1.3 Measurable Storm Events.

All required monitoring must be performed on a storm event that results in an actual discharge from your site (“measurable storm event”) that follows the preceding measurable storm event by at least 72 hours (3 days). The 72

- hour (3 -day) storm interval doe s not apply if you

are able to document that less than a 72

- hour (3

- day) interval is representative for local storm events during the sampling period. In the case of snowmelt, the monitoring must be performed at a time when a measurable discharge occurs at your site.

For each monitoring event, except snowmelt monitoring, you must identify the date and 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. For snowmelt monitoring, you must identify the date of the sampling event.

6.1.4 Sample Type.

You must take a minimum of one grab sample from a discharge resulting from a measurable storm event as described in Part 6.1.3. Samples must be collected within the first 30 minutes of a measurable storm event. If it is not possible to collect the sample within the first 30 minutes of a measurable storm event, the sample must be collected as soon as practicable after the first 30 minutes and documentation must be kept with the SWPPP explaining why it was not possible to take samples within the first 30 minutes. In the case of snowmelt, samples must be taken during a period with a measurable discharge.

6.1.5 Adverse Weather Conditions.

When adverse weather c onditions as described in Part 3.2 .3 prevent the collection of samples according to the relevant monitoring schedule, you must take a substitute sample during the next qualifying storm event. Adverse weather does not exempt you from having to file a benchmark monitoring report in accordance with your sampling schedule. You must report any failure to monitor as specified in Part 7.4 indicating the basis for not sampling during the usual reporting period.

6.1.6 Climates with Irregular Stormwater Runoff.

If your facility is located in areas where limited rainfall occurs during parts of the year (e.g., arid or semi- arid climates) or in areas where freezing conditions exist that prevent runoff from occurring for extended periods, required monitoring events may be distributed during seasons when precipitation occurs, or when snowmelt results in a measurable discharge from your site. You must still collect the required number of samples.

6.1.7 Monitoring Periods.

Monitoring requirements in this permit begin in the first full quarter following either January 1, 2014 or your date of discharge authorization, whichever date comes later. If your monitoring is

Page 33 of 146Proposed 2013 MSGP

required on a quarterly basis (e.g., benchmark monitoring), you must monitor at least once in each of the following 3

- month intervals:

• January 1 – March 31;

• April 1 – June 30;

• July 1 – September 30; and

• October 1 – December 31.

For example, if you obtain permit coverage on June 2, 2014, then your first monitorin g quarter is July 1 - September 30, 2014. This monitoring schedule may be modified in accordance with Part 6.1.6 if the revised schedule is documented with your SWPPP and provided to EPA with your first monitoring report.

6.1.8 Monitoring for Allowable Non

- Stormwater Discharges

.

You are only required to monitor allowable non

- stormwater discharges (as delineated in Part 1.1.3) when they are commingled with stormwater discharges associated with industrial activity.

6.2 Req uired Monitoring.

This permit includes five types of required analytical monitoring, one or more of which may apply to your discharge:

• Quarterly benchmark monitoring (see Part 6.2.1)

• Annual effluent limitations guidelines monitoring (see Part 6.2.2);

• State - or tribal- specific monitoring (see Part 6.2.3);

• Impaired waters monitoring (see Part 6.2.4); and

• Other monitoring as required by EPA (see Part 6.2.5).

When more than one type of monitoring for the same parameter at the same outfall applies (e.g., total suspended solids once per year for an effluent limit and once per quarter for benchmark monitoring at a given outfall), you may use a single sample to satisfy both monitoring requirements (i.e., one sample satisfying both the annual effluent limit sample and

one of the four quarterly benchmark monitoring samples).

All required monitoring must be conducted in accordance with the procedures described in Appendix B, Subsection 10.D.

6.2.1 Benchmark Monitoring.

This permit specifies pollutant benchmark concentrations that are applicable to certain
sectors / subsectors. Benchmark monitoring data are primarily for your use to determine the

overall effectivene ss of your control measures and to assist you in knowing when additional corrective action(s) may be necessary to comply with the effluent limitations in Part 2.

The benchmark concentrations are not effluent limitations; a benchmark exceedance,

therefore , is not a permit violation. However, if corrective action is required as a result of a benchmark exceedance, failure to conduct required corrective action is a permit violation.

Page 34 of 146Proposed 2013 MSGP

At the Permittee’s discretion, more than four samples may be taken during se parate runoff events and used to determine the average benchmark parameter concentration for facility discharges.

6.2.1.1 Applicability of Benchmark Monitoring. You must monitor for any benchmark parameters specified for the industrial sector(s), both primary industrial activity and any

co

- located industrial activities, applicable to your discharge. Your industry

- specific

benchmark concentrations are listed in the sector

- specific sections of Part 8. If your facility is in one of the industrial sectors subject to benchmark concentrations that are

hardness

- dependent, you are required to submit to EPA with your first benchmark report a hardness value, established consistent with the procedures in Appendix J, that is representative of your receiving water.

Samples must be analyzed consistent with 40 CFR Part 136 analytical methods and using test procedures with quantitation limits at or below benchmark values for all benchmark parameters for which you are required to sample.

6.2.1.2 Benchmark Monitoring Sch edule. Benchmark monitoring must be conducted quarterly, as identified in Part 6.1.7, for your first four full quarters of permit coverage commencing no earlier than January 1, 2014. Facilities in climates with irregular stormwater runoff, as described in Part 6.1.6, may modify this quarterly schedule provided that this revised schedule is reported to EPA when the first benchmark sample is collected and reported, and that this revised schedule is kept with the facility’s SWPPP as specified in Part 5.5.

When conditions prevent you from obtaining four samples in four consecutive quarters, you must continue monitoring until you have the four samples required for calculating your benchmark monitoring average.

Data not exceeding benchmarks : After collection of four quarterly samples, if the average of the four monitoring values for any parameter does not exceed the benchmark, you have fulfilled your monitoring requirements for that parameter for the permit term.

Data exceeding benchmarks : After collection o f four quarterly samples, if the average

of the four monitoring values for any parameter exceeds the benchmark, you must, in accordance with Part 4, review the selection, design, installation, and implementation of your control measures to determine if modifications are necessary to meet the effluent limits in this permit, and either:

• Make the necessary modifications and continue quarterly monitoring until you have completed four additional quarters of monitoring for which the average

does not exceed th e benchmark; or

• Make a 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

th e water

- quality

- based effluent limitations in Parts 2.1 and 2.2 of this permit, in which case you must continue monitoring once per year. You must also document your rationale for concluding that no further pollutant reductions are achievable, and retain all records related to this documentation with your

SWPPP.

Page 35 of 146Proposed 2013 MSGP

In accordance with Part 4, you must review your control measures and perform any required corrective action immediately (or document why no corrective action is required), without waiting for the full four quarters of monitoring data, if an exceedance

of the four quarter average is mathematically certain. If after modifying your control measures and conducting four additional quarters of monitoring, your average still exceeds the benchmark (or if a n exceedance of the benchmark by the four quarter average is mathematically certain prior to conducting the full four additional quarters of monitoring), you must again review your control measures and take one of the two

actions above.

Natural background pollutant levels : Following the first four quarters of benchmark monitoring (or sooner if the exceedance is triggered by less than four quarters of data, see above), if the average concentration of a pollutant exceeds a benchmark value, and you determine that exceedance of the benchmark is attributable solely to the presence of that pollutant in the natural background, you are not required to perform corrective action or additional benchmark monitoring provided that:

• The average concentration of your benchmark monitoring results is less than or equal to the concentration of that pollutant in the natural background;

• You document and maintain with your SWPPP, as required in Part 5.5, your supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background pollutant levels. You must include in your supporting rationale any data previously collected by you or others (including literature studies) that describe the levels of natural background pollutants in yo ur stormwater discharge; and

• You notify EPA on your final quarterly benchmark monitoring report that the benchmark exceedances are attributable solely to natural background pollutant

levels.

Natural background pollutants include those substances that are naturally occurring in soils or ground water. Natural background pollutants do not include legacy pollutants from earlier activity on your site, or pollutants in run

- on from neighboring sources which are not naturally occurring

, such as other industrial s ites or roadways . However, permittees may be eligible to discontinue monitoring for pollutants that occur solely from

run

- on sources and should consult the appropriate EPA Regional Office for related guidance

.

6.2.1.3 Exception for Inactive and Unstaffed Sites. The requirement for benchmark monitoring does not apply at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. To invoke this exception, you must do the following:

• Maintain a statement with your SWPPP stating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to stormwater in accordance with the substantive requirements in 40 CFR 122.26(g) and sign and certify the statement in accordance with Appendix B, Subsection
11; and

• If circumstances change and industrial materials or activities become exposed to stormwater or your facility becomes active and/or staffed, this exception no longer applies and you must immediately begin complying with the applicable benchmark monitoring requirements under Part 6.2 as if you were in your first year

Page 36 of 146Proposed 2013 MSGP

of permit coverage. You must indicate in your NOI that your facility has materials or activities exposed to stormwater or has become active and/or staffed.

• If you are not qualified for this exception at the time you are authorized under this permit, but during the permit term you become qualified because your facility is
inactive and unstaffed, and there are no industrial materials or activities that are exposed to stormwater, then you must notify EPA of this change in your next benchmark monitoring report. You may discontinue benchmark monitoring once you have notified EPA, and prepared and signed the certification statement

described above concerning your facility’s qualification for this special exception.

Note: This exception has different requirements for Sectors G, H, and J (see Part 8).

6.2.2 Effluent Limitations Monitoring.

6.2.2.1 Monitoring Based on Effluent Limitations Guidelines. Table 6

- 1 identifies the stormwater discharges subject to effluent limitation guidelines that are authorized for coverage under this permit. Beginning in the first full quarter following January 1, 2014 or your date of discharge authorization, whichever date comes later, you must monitor once per year at each outfall containing the discharges identified in Table 6 -1 for the parameters specified in the sector

- specific section of Part 8.

6.2.2.2 Substantially Identical Outfalls. You must monitor each outfall dischargi ng runoff from any regulated activity identified in Table 6

- 1. The substantially identical outfall monitoring provisions are not available for numeric effluent limits monitoring.

6.2.2.3 Follow

- up Actions if Discharge Exceeds Numeric Effluent Limit. You must conduct follow

up monitoring within 30 calendar days (or during the next qualifying runoff event, should

Page 37 of 146Proposed 2013 MSGP

none occur within 30 days) of implementing corrective action(s) taken pursuant to Part 4 in response to an exceedance of a numeric effluent limit contained in this permit. See Part 9 for specific monitoring requirements applicable to individual states or tribes. Monitoring must be performed for any pollutant(s) that exceeds the effluent limit. If this

follow

- up monitoring exceeds the applicable effluent limitation, you must:

• Submit an Exceedance Report: You must submit an Exceedance Report no later than 30 days after you have received your lab result consistent with Part 7.6; and

• Continue to Monitor: You must monitor, at least quarterly, until your discharge is in compliance with the effluent limit or until EPA waives the requirement for additional monitoring.

6.2.3 State or Tribal Monitoring Provisions

.

6.2.3.1 Sectors Required to Conduct State o r Tribal Monitoring. You must comply with any state or tribal monitoring requirements (see Part 9) applicable to your facility’s location.

6.2.3.2 State or Tribal Monitoring Schedule. If a monitoring frequency is not specified for an applicable requirement in Part 9, you must monitor once per year for the entire permit

term.

6.2.4 Discharges to Impaired Waters Monitoring.

6.2.4.1 Permittees Required to Monitor Discharges to Impaired Waters. If you discharge to an impaired water, you must monitor all pollutants for which the waterbody is impaired and for which a standard analytical method exists (see 40 CFR Part 136). See EPA’s Discharge Mapping Tool which provides information on the i mpairment status of the water, potential pollutants of concern, as well as applicable total maximum daily loads (TMDLs). For the purposes of this permit, a permittee discharges to an impaired water if the discharge flows directly to the impaired water.

Note: Your project will be considered to discharge to an impaired water if the first water of the U.S. to which you discharge is identified by a state, tribe, or EPA pursuant to Section 303(d) of the CWA as not meeting an applicable water quality standar d, or is

included in an EPA

- approved or established total maximum daily load (TMDL). For discharges that enter a storm sewer system prior to discharge, the first water of the U.S. to which you discharge is the waterbody that receives the stormwater discharge from the storm sewer system.

If the pollutant of concern for the impaired waterbody is suspended solids, turbidity or sediment/sedimentation, you must monitor for Total Suspended Solids (TSS). If a pollutant of concern is expressed in the form of an indicator or surrogate pollutant, you must monitor for that indicator or surrogate pollutant. No monitoring is required when a waterbody’s biological communities are impaired but no pollutant, including indicator or surrogate pollutants, is specified as causing the impairment, or when a waterbody’s impairment is related to hydrologic modifications, impaired hydrology, or other non

pollutant. Permittees should consult the appropriate EPA Regional Office for any available guidance regarding required monitoring parameters under this part.

Page 38 of 146Proposed 2013 MSGP

If the Discharge Mapping Tool does not provide the information you need, you may consult the appropriate EPA Regional Office for guidance regarding required monitoring parameters under this part.

6.2.4.2 Impaired Wate rs Monitoring and Schedule

.

Discharges to impaired waters without an applicable EPA

- approved or established TMDL

WLA: Beginning in the first full quarter following January 1, 2014 or your date of discharge authorization, whichever date comes later, you must monitor once per year at each outfall (except substantially identical outfalls) discharging stormwater to impaired waters without an applicable EPA

- approved or established TMDL waste load allocation. This monitoring requirement no longer applies once the pollutant of concern is not detected above natural background levels in your stormwater monitoring results, and you document, as required in Part 5.5 (Additional Documentation Requirements), that this pollutant is not expected to be present above natural background levels in your discharge.

If the pollutant of concern is not present and not expected to be present in your discharge, or it is present but you have determined that its presence is caused solely by natural background sources, you must includ e a notification to this effect in your first monitoring report, after which you may discontinue monitoring. To support a determination that the pollutant’s presence is caused solely by natural background sources, you must document and maintain with your S WPPP, as required by Part 5.5:

• An explanation of why you believe that the presence of the pollutant of concern in your discharge is not related to the activities or materials at your facility; and

• Data and/or studies that tie the presence of the pollutant of concern in your discharge to natural background sources in the watershed.

Natural background pollutants include those that occur naturally as a result of native soils, and vegetation, wildlif e, or ground water. Natural background pollutants do not include legacy pollutants from earlier activity on your site, or pollutants in run

- on from neighboring sources that are not naturally occurring. However, permittees may be eligible to discontinue annual monitoring for pollutants that occur solely from these sources and should consult the appropriate EPA Regional Office for related guidance.

Discharges to impaired waters with an EPA

- approved or established TMDL WLA: For stormwater discharges to wat ers for which there is an EPA approved or established TMDL waste load allocation, you are not required to monitor for the pollutant for which the TMDL was written unless EPA informs you, upon examination of the applicable TMDL and/or WLA, that you are subj ect to such a requirement consistent with the assumptions of the applicable TMDL and/or WLA. EPA’s notice will include specifications on which pollutant to monitor and the required monitoring frequency. Permittees must consult the appropriate EPA Regional Office for guidance regarding required monitoring under this part.
