Attn: Thomas J. Roberts, President and CEO 202 Mackenan Drive Cary, NC 27511 Subject: Compliance Evaluation Inspection Permittee: Aqua NC Inc. Facilities: Wellesley Place Wastewater Treatment Plant, NCO084409 Forest Ridge Wastewater Treatment Plant, NCO063720 Frye Bridge Wastewater Treatment Plant, NCO065587 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 compliance evaluation inspections (CEI) of the subject facilities on November 12, 2015. The assistance and cooperation of Samuel Pegram, Operator in Responsible Charge, was greatly appreciated. Inspection checklists are attached for your records and inspection findings are summarized below. Wellesley Place Wastewater Treatment Plant, NCO084409 General Information The Wellesley Place Wastewater Treatment Plant is located in the Wellesley Place subdivision in Lewisville, Forsyth County, NC at approximate coordinates 36.1181370N, 80.4175420W. The permit authorizes Aqua to operate this 0.06 MGD WWTP, which consists of a bar screen, equalization basin, dual pumps and blowers, flow splitter box, dual aeration basins with fine bubble diffusers and blowers, dual basin clarifier, UV disinfection, backup dual tablet chlorinators and dechlorinators and a chlorine contact chamber, aerobic sludge digester, and an effluent flow meter with a weir. The permit authorizes Aqua to discharge the treated effluent from the WWTP via outfall 001 to Mill Creek, which is currently classified as WS -IV waters and is located in the Yadkin Pee -Dee river basin. Site Review Plant operation and maintenance was reviewed with Mr. Pegram. He is doing an excellent job as the plant was found to be well operated and maintained. No issues were noted. 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. This includes operations and visitation logs, discharge monitoring reports, laboratory and field laboratory records, chains of custody, etc. 450 West Hanes Mill Road, Suite #300, Winston-Salem, North Carolina 27105 Phone: 336-776-98001 Internet: www.ncdenr.gov An Equal Opportunity 1 Affirmative Action Employer — Made in part by recycled paper Forest Ridge Wastewater Treatment Plant, NC0063720 General Information The Forest Ridge Wastewater Treatment Plant is located near 6931 August Drive in Clemmons, Forsyth County, North Carolina, at approximate coordinates 36.060669° West, 80.397985° North. Aqua NC is authorized to operate this 0.033 million -gallon -per -day (MGD) wastewater treatment plant, which consists of aeration, secondary clarification, tablet chlorination, tablet dechlorination, post aeration, and sludge holding, and discharge treated effluent from outfall 001 of said treatment works, which is located approximately 270 feet east of the treatment works at approximate coordinates 36.060804° West, 80.397024° North, to Blanket Creek, which is currently classified as Class WS -IV (water supply) waters and is located in the Yadkin Pee - Dee River Basin. Site Review Mr. Boone reviewed the entire plant with Mr. Pegram. No discrepancies or violations were noted. The plant appears to be operated and maintained very well. DOCUMENTATION REVIEW Mr. Pegram had all required documentation for the inspection and everything was complete and current. Mr. Boone found no discrepancies or violations. Mr. Pegram has done an excellent job of documenting his operation and maintenance of the plant. Frye Bridge Wastewater Treatment Plant, NC0065587 General Information The Frye Bridge Wastewater Treatment Plant is located in Clemmons, Forsyth County, NC at approximate coordinates 35.9889130N, 80.3534080W. 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. There is still significant corrosion in the plant that should be addressed as soon as possible. This issue has been mentioned in the two inspection letters previous to this one (about two years). 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. This includes operations and visitation logs, discharge monitoring reports, laboratory and field laboratory records, chains of custody, etc. The Division greatly appreciates the efforts of Aqua and Mr. Pegram in running these plants effectively and efficiently. Please consider an in-depth evaluation of the Frye Bridge WWTP to determine what can be done to address the corrosion problem at that plant. Please remember that violations of these NPDES permits, as well as the NC rules and regulations that implement them, are subject to civil penalties not to exceed $25,000 per violation, per day. If you have any questions regarding these inspections or this letter, please call Mr. Boone or me at (336) 776-9800. Thank you for your cooperation in this matter. Sincerely, Sherri V. Knight Asst.
