KIM, DIRECTOR 217/782-0610 August 20, 2021 Exelon Generation Company, LLC Braidwood Nuclear Power Station 35100 South Route 53 Braceville, IL 60407-9619 Re:        Exelon Generation Company, LLC Braidwood Nuclear Power Station NPDES Pennit No. IL004832 l BOW ID: Wl978160003 Final Pem1it Gentlemen:
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|date=August 4, 2021|text=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.

Page 2 If your facility has received a waiver from the NetDMR program, a supply of preprinted paper DMR Fom1s will be sent to your facility during the interim period prior to your registration in the NetDMR program. 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.
Should you have questions concerning the Pennit, please contact Keegan MacDonna at the 217/782-0610.

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.

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 hours 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.

: 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),
