VAN DER VAART Secrel..I S. JAY ZIMMERMAN Dwecmr Shuying Wang and Lon Snider of the Winston-Salem Regional Office of the North Carolina Division of Water Resources (DWR or the Division) conducted a compliance evaluation inspection of the Belews Creek Steam Station Wastewater Treatment Plant (WWTP) on March 2, 2016. Your assistance and cooperation were greatly appreciated. Inspection findings are summarized below and an inspection report is attached for your records. The facility is located at 319 Pine Hall Road, Belews Creek, Stokes County, North Carolina. The permit authorized Duke Energy to discharge from two separate outfalls. Outfall 001 discharges into West Belews Creek/Belews Lake. The effluent from this discharge consists of intake screen backwash water, recirculating cooling water, equipment cooling water, and once -through cooling water. Outfall 003 (the coal ash basin discharge) discharges to the Dan River, which is classified as WS-IV waters in the Roanoke River Basin. The coal ash basin water consists of wastestreams from the power house and yard holding sumps, ash sluice lines, chemical holding pond, coal yard sumps, stormwater and remediated groundwater, and treated FGD wastewater from internal Outfall 002. Site Review The facility was clean and well secured. Major components of the treatment system were inspected and found to be operational. No discrepancies from the permit were noted. Two outfalls (001 and 003) and one internal outfall (002) were inspected as well. Effluent water or receiving water at outfalls was free of foam and other debris. Documentation Review Laboratory data were evaluated during the inspection. Comparison of lab reports and monitoring data with discharge monitoring reports (DMRs) showed no concerns or errors. Chain of custody records were available and complete. The Duke Energy internal laboratory performed required lab testing for the 450 West Hanes Mill Road, Suite 300, Winston-Salem, NC 27105 Phone: 336-776-9800 \ Internet: www.ncwaterguality.org An EouaI Onoortunity\ Affirmative Action Emnlover —Made in oart by recycled caner facility, except for mercury.
