January 5, 2021 Sergei Chemikov, PhD North Carolina Department of Environmental Quality Division of Water Resources 1617 Mail Service Center Raleigh, NC 27699-1617 Subject: Marshall Stearn station NPDES Permit NC0004987 NPDES permit modification request Dear Dr. Chemikov: Marshall Steam Statton 8320 East NC Nrghway 50 Terrell, NC 28682 Duke Energy requests that NPDES permit # NC0004987 be modified to incorporate recently modified steam electric Federal Effluent Guidelines (40 CFR Part 423). It is requested that purge water from the bottom ash handling system be permitted as a contributing wastewater source to outfall 005. Purge water from the bottom ash submerged flight conveyer (SFC) handling system will primarily be directed to be used for FGD makeup water when available but, as allowed in the modified rule in accordance with 40 CFR 423.13(k)(2)(i)(A), this purge water may be released to the lined retention basin for treatment and then discharged through outfall 005 as needed to maintain water system chemistry and/or water balance. In accordance with the updated federal effluent guideline rule, a 30-day rolling average SFC purge water flow volume of 0.098 MGD is requested to be added to the permit based on a calculated bottom ash system volume of 0,983 million gallons. Duke Energy requests that this be added as a special condition. Additionally, Duke Energy requests for internal outfall 006 that the amended concentration limits for FGD wastewater found in the modified rule be incorporated into the permit. Those limits are as follows with changes from current permit limits highlighted: Pollutant Arsenic Mercury Selenium Nitrate/Nitrite Existing monthly average/daily max 8 ug/I and 11 /ug/I 356 ng/I and 788 nq/1 12 ug/I and 23 uq/1 4.4 mg/I and 17 mg/I Modified Rule monthly average/daily_max Bug/land 18ug/I 1 34 ng/I and 103 nag/1 19 uq/I and 70 ug/I 3 mg/land 4 m /1 Dr. Sergei Chemikov North Carolina Department of Environmental Quality Division of Water Resources January 5, 2021 Duke Energy request the pH limits at internal outfall 006 be removed. The pH of the wastewater is adjusted as needed later in the treatment process and prior to discharging from the final outfall 005. This change is consistent with other Duke Energy permits where pH was removed from internal outfalls. Internal outfall 006 is subject to the Federal Effluent Guidelines 40 CFR 423 and these guidelines do not include pH. Attached is a check for $1,030 in order to process this modification request.
