Water Quality Facility: Frye Bridge Wastewater Treatment Plant Permitting Section NPDES Permit#: NC0065587 Forsyth County Dear Mr. Roberts: Ron Boone of the Winston-Salem Regional Office of the NC Division of Water Resources (DWR or the Division) conducted a compliance evaluation inspection (CEI) of the Frye Bridge Wastewater Treatment Plant (WWTP) on May 19, 2015. The assistance and cooperation of Sam Pegram, Operator in Responsible Charge, was greatly appreciated. An inspection checklist is attached for your records and inspection findings are summarized below. General Information The Frye Bridge Wastewater Treatment Plant is located in Winston-Salem, Forsyth County, NC at approximate coordinates 35.988913°N, 80.353408°W. The permit authorizes Aqua to operate this 0.027 MGD WWTP, which consists of a bar screen, aeration basin, clarifier, aerated sludge holding tank, tablet chlorinator, chlorine contact chamber, tablet dechlorinator, and post aeration. The permit authorizes Aqua to discharge the treated effluent from the WWTP via outfall 001 to an unnamed tributary to Muddy Creek. Muddy Creek is currently classified as Class C waters and is located in the Yadkin Pee-Dee river basin. Site Review Mr. Pegram has done an excellent job operating and maintaining the plant. The plant was clean and well maintained, except for a significant amount of corrosion in the plant. This was noted in the last inspection as well and nothing has been done to address it yet. The plant is operated quite well and sludge/solids are being effectively managed. Odors at the plant were minimal. Documentation Review All documentation was reviewed and no discrepancies were found. Mr. Pegram has done an excellent job documenting the operation and maintenance of the plant as required by the permit.
