Attached is the final NPDES Permit for your discharge. The Permit as issued covers discharge limitations, monitoring, and reporting requirements. Failure to meet any portion of the Pennit could result in civil and/or criminal penalties. The Illinois Environmental Protection Agency is ready and willing to assist you in interpreting any of the conditions of the Penn it as they relate specifically to your discharge.

In reference to the comments in your letter dated August 4, 2021, the Agency offers the following response:

I. The name and address of the Discharger were changed to match the name and address of the facility on Page 1 of the Fact Sheet.

2. The name and address of the Discharger were changed to match the name and address of the facility on Page I of the Permit.

3. The language in the second sentence of the first paragraph of Special Condition 4 was not changed, because including outfall 005 in the manner requested would imply that there is a defined mixing zone for outfall 005.

Outfall 001 does have a defined mixing zone, but outfall 005 only has allowed mixing for them1al discharges.

4. The language in Special Condition 9.S has been changed per Exelon 's request. The infom1ation collection period for annual inspections shall now begin on July l s1 each year, with the associated inspection report due for submission .

to the Agency by September 30'h of the following year.

5. The language in Special Condition 9.U has been changed per Exelon's request, allowing annual inspection reports to be submitted to the Agency electronically or by mail. Previously, both fonns of submission were required.

6. The language in Special Condition l l has been changed per Exelon's request, shifting the due date for DMRs for a given month to the 28 th day of the following month. Previously, DMRs were due on the 25 th day of the following month.

Pursuant to the Final NPDES Electronic Reporting Rule, all pem1ittees must report DMRs electronically unless a waiver has been granted by the Agency. The Agency utilizes NetDMR, a web based application, which allows the submittal of electronic Discharge Monitoring Reports instead of paper Discharge Monitoring Reports (DMRs). More information regarding NetDMR can be found on the Agency website, hups) "ww2.illinois.go\ *\::pa topics watcr-qualitv surfacc-water/netdmr/Pages/quick-answer-guide.asi:2x.

Additional information and instructions will accompany the preprinted DMRs. P!ease see the attachment regarding the electronic reporting rule.

The attached Pern1it is effective as of the date indicated on the first page of the Penn it. Until the effective date of any re.

issued Permit, the limitations and conditions of the previously-issued Permit remain in full effect You have the right to appeal any condition of the Permit to the Illinois Pollution Control Board within a 35 day period following the issuance date.

5, Storm Water Management Practices

• Storm water management practices are practices other than those which control the source of pollutants. They include measures such as installing oil and grit separators, diverting storm water into retention basins, etc. Based on assessment of the potential of various sources to contribute pollutants, measures lo remove pollutants from storm water discharge shall be implemented. In developing the p!an, the following management practices shall be considered:

L Containment

• Storage within berms or other secondary containment devices to prevent leaks and spills from entering storm

• water runoff. To the maximum extent practicable storm water discharged from any area where material handling equipment or activities, raw material, intermediate products, final products, waste materials, by-products, or Industrial machinery are exposed to storm water should not enter vegetated areas or surface waters or infiltrate into the soil unless adequate treatment is provided.

ii. Oil & Grease Separation - Oil/water separators, booms, skimmers or other methods to minimize oil contaminated storm water discharges.

iii. Debris & Sediment Control - Screens, booms, sediment ponds or other methods to reduce debris and sediment in storm water discharges.

iv. Waste Chemical Disposal - Waste chemicals such as antifreeze, degreasers and used oils shall be recycled or disposed of in an approved manner and in a way which prevents them from entering storm water discharges.

v. Storm Water Diversion - Storm water diversion away from materials manufacturing, storage and other areas of potential storm waler contamination. Minimize !he quantity .of storm water entering areas where material handling equipment of activities, raw material, intermediate products, final products, waste materials, by-products, or industrial machinery are exposed to storm waler using green infrastructure techniques where practicable in the areas outside the exposure area, and otherwise divert storm waler away from exposure area.

vi. Cov~red Storage or Manufacturing Areas - Covered fueling operations, materials manufacturing and storage areas to prevent contact with storm water.

vii. Storm Water Reduclion - install vegetation on roofs of buildings within or adjacent to the exposure area to detain and evapotranspirate runoff where precipitation falling on the roof is not exposed to contaminants, to minimize storm water runoff; capture storm waler in devices that minimize the amount of storm water runoff and use this water as appropriate based on quality.

6. Sediment and Erosion Prevention - The plan shall identify areas which due to topography, activities, or other factors, have a hlgh potential for significant soil erosion. The plan shall describe measures to limit erosion.

7. Employee Training - Employee training programs shall inform personnel at all levels of responsibility of the components and goals of the storm water pollution control plan. Training should address topics such as spill response, good housekeeping and material management practices, The plan shall identify periodic dates for such training.

8. Inspection Procedures - Qualified plant personnel shall be identified to inspect designated equipment and plant areas, A tracking or follow-up procedure shall be used to ensure appropriate response has been taken in response to an inspection. Inspections and maintenance activities shall be documented and recorded.

G. Non-Storm Water Discharge

• The plan shall include a certification that the discharge has been tested or evaluated for the presence of non-storm water discharge. The certification shall include a description of any lest for the presence of non-storm water discharges, the methods used, the dates of the testing, and any onsite drainage points that were observed during !he testing. Any facility that is unable to provide this certification must describe the procedure of any test conducted for the presence of non-storm water discharges, the test results, potential sources of non-storm water discharges lo the storm sewer. and why adequate tests for such storm sewers were not feasible.

H. Quarterly Visual Observation of Discharges - The requirements and procedures far quarterly visual obser..ations are applicable to all outfalls covered by this condition.

1. You must perform and document a quarterly visual observation of a storm water discharge associated with industrial activity from each outfaH. The visual observation must be made during daylight hours. If no storm event resulted in runoff during daylight

Page 14 NPDES Permil No. il0048321 Special Conditions hours from the facility during a monitoring quarter, you are excused from the visual observations requirement for that quarter, provided you document in your records that no runoff occurred. You must sign and certify lhe document.

2. Your visual observation must be made on samples collected as soon as practical, but not to exceed 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or when the runoff or snow melt beglns discharging from your facility. Ail samples must be collected from a storm event discharge that is greater than 0.1 inch in magnitude and that occurs at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> from the previously measureable (greater than 0.1 inch rainfall) storm event. The observation must document: color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of storm water porlution. If visual observations indicate any unnatural color, odor, turbidity, floatable material, oil sheen or other indicators of stomi water pollution, the permitlee shall obtain a sample and monitor for the parameter or the list of pollutants !n Part E.4.

3. You must maintain your visual observation reports onsite with the SWPPP. The report mus! include the obsetVation date and lime, inspection personnel, nature of the discharge (Le., runoff or snow melt), visual quality of the storm water discharge (including observations of color, odor, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of storm water pollution), and probable sources of any observed storm water contamination.

4. You may exercise a waiver of the visual *observation requirement at a facility that is inactive or unstaffed, as long as there are no industrial materials or activities exposed to storm water. If you exercise this waiver, you must maintain a certification with your SWPPP stating that the site is inactive and unstaffed, and Iha! there are no industrial materials or activities exposed to storm water.

5. Representative Outfalls - If your facility has two or more outfalls that you believe discharge substantially identical effluents, based on similarities of the industrial activities. significant materials, size of drainage areas, and storm water management practices occurring within the drainage areas of the outfalls, you may conduct visual observations of the discharge at just one of the outfalls and report that the results also apply to the substantially identical outfa!l(s),

6. The visual observation documentation shall be made available to the Agency and general public upon written request L The permittee shall conduct an annual facility inspection to verify that all elements of the plan, including the site map, potential pollutant sources, and structural and non-structural controls to reduce pollutants in industrial storm waler discharges are accurate.

Observations that require a response and the appropriate response to the observation shall be retained as part of the plan. Records documenting significant observations made during !he site inspection shall be submitted to the Agency in accordance with the reporting requirements of this permit

• J. This plan should briefly describe the appropriate elements of other program requirements, including Spill Prevention Control and Countermeasures (SPCC) plans required under Section 311 of the CWA and the regulations promulgated there under, and Best Management Programs under 40 CFR 125.100.

K. The plan ls considered a report that shall be available to the public at any reasonable time upon request L. The plan shall include the signature and title of the person responsible for preparation of the plan and include the* date of initial preparation and each amendment thereto.
