Box 2511 JUN 0 3 Z015 Winston-Salem, NC 27102-2511 Water Quality Subject: Compliance Evaluation Inspections 7;n:1378347a: Archie Elledge Wastewater Treatment Plant, NPDES Permit Muddy Creek Wastewater Treatment Plant, NPDES Permit NC0050342 City of Winston-Salem Forsyth County Dear Mr. Hargrove: Ron Boone of the Winston-Salem Regional Office of the NC Division of Water Resources (DWR or the Division) conducted compliance evaluation inspections (CEI) of the Archie Elledge Wastewater Treatment Plant (NC0037834) and the Muddy Creek Wastewater Treatment Plant (NC0050342) on May 21, 2015. The assistance and cooperation of Jon Southern, Keith Jones, and Carol Bell, during these inspections, was greatly appreciated. Inspection checklists are attached for your records and inspection findings are summarized below. Archie Elledge Wastewater Treatment Plant, NPDES Permit NC0037834 General Information The WWTP is located at 2801 Griffith Road in Winston Salem, Forsyth County, NC. The permit authorizes the City to operate this 30 MGD WWTP, which consists of bar screens, grit basins, primary clarifiers, aeration basins, final clarifiers, sodium hypochlorite and bisulfite feed for disinfection and dechlorination, lime/magnesium hydroxide blend and caustic feed for alkalinity control, centrifuges with screw conveyors, sludge digestion, polymer and iron salt feed, odor control systems, a sludge drying facility, waste sludge lagoons and instrumented flow measurement. The permit authorizes the City to discharge treated effluent from the plant via outfall 001 into Salem Creek, this section of which is currently classified as Class C waters in the Yadkin Pee-Dee river basin. Site Review As was also the case during the previous inspection, Mr. Southern and his crew continue to do an outstanding job operating and maintaining the plant. Mr. Boone noted no issues or discrepancies. Documentation Review 450 West Hanes Mill Road,Suite#300,Winston-Salem,North Carolina 27105 Phone:336-776-98001 Internet:www.ncdenr.gov An Equal Opportunity\Affirmative Action Employer—Made in part by recycled paper All documentation was reviewed. Mr. Southern and his staff, as well as Carol Bell and the laboratory staff, have done an excellent job of documenting the operation and maintenance of the plant and laboratory operations, as required by the permit; this includes operations/maintenance and operator visitation logs, discharge monitoring reports, laboratory and field laboratory records, chains of custody, etc. Muddy Creek Wastewater Treatment Plant, NPDES Permit NC0050342 General Information The WWTP is located at 4561 Cooper Road in Winston Salem, Forsyth County, NC. The permit authorizes the City to operate this 21 MGD WWTP, which consists of bar screens, grit chambers, primary clarification, three aeration basins with fine bubble diffusers, a hydrated lime silo, secondary clarification, chlorination, dechlorination, instrumented flow measurement, anaerobic sludge digesters, a gravity thickener, sludge storage lagoons, a belt filter press, a carbon pellet odor scrubber, two emergency generators, an effluent/flood control pump station, and solids blending tanks. The permit authorizes the City to discharge treated effluent from this facility into the Yadkin River(outfall 001) or, under flood conditions, into Muddy Creek (outfall 002). Both receiving waters are currently classified as WS-IV (water supply) waters in the Yadkin Pee- Dee River Basin. Site Review As was the case during the previous inspection, Mr. Jones and his crew continue to do an outstanding job operating and maintaining the plant. Mr. Boone noted no problems, discrepancies, violations, etc., during the site review portion of the inspection. Documentation Review All documentation was reviewed. Mr. Jones and his staff, as well as Carol Bell and the laboratory staff, have done an excellent job of documenting the operation and maintenance of the plant and laboratory operations, as required by the permit; this includes operations/maintenance and operator visitation logs, discharge monitoring reports, laboratory and field laboratory records, chains of custody,etc. The Division greatly appreciates the City's efforts to effectively and efficiently operate and maintain the Elledge and Muddy Creek WWTPs. Mr. Southern and Mr.Jones, and their crews, as well as Carol Bell and the laboratory staff, have done an excellent job and should be commended for their efforts.
