JAY ZIMMERMAN Director December 7, 2015 Aqua North Carolina, Inc. Attn: Thomas J. Roberts, President 202 Mackenan Court Cary, NC 27511 RECEIVEDIDENRIDWR SUBJECT: Compliance Evaluation Inspections Mikkola Downs Subdivision WWTP, NC0067091; DEC 1 0 2015 Greystone Subdivision, NC0078115; and, Salem Quarters WWTP, NCO083933 Water Quality Permittee:Aqua North Carolina, Inc. Permitting Section Forsyth County Dear Mr. Roberts, Ron Boone of the Winston Salem Regional Office (WSRO) of the North Carolina Division of Water Resources (DWR or the Division) conducted compliance evaluation inspections of the Mikkola Downs Wastewater Treatment Plant, the Greystone Subdivision, and the Salem Quarters Wastewater Treatment Plant, on December 1, 2015. The assistance and cooperation of Morgan Turner, Operator in Responsible Charge (ORC), was greatly appreciated. Inspection reports are attached for your records and inspection findings are summarized below. Mikkola Downs Wastewater Treatment Plant, NCO067091 General Information The Mikkola Downs Wastewater Treatment Plant is located near 2777 Stable Hill Trail in Kernersville, Forsyth County, North Carolina, at approximate coordinates 36.182120° West, 80.053833° North. Aqua NC is authorized to operate this 0.072 million-gallon-per-day (MGD) wastewater treatment plant, which consists of a-flow splitter box,bar screen,dual aeration tanks,dual blowers,dual clarifiers,sludge holding tank, Sanuril tablet chlorinator, chlorine contact tank, dechlorination, post aeration tank, and an effluent flow recorder, and discharge treated effluent from outfall 001 of said treatment works, which is located approximately 150 feet southwest of the treatment works at approximate coordinates 36.1825260 West, 80.054143° North, to East Belews Creek, which is currently classified as Class C waters and is located in the Roanoke River Basin. Site Review Mr. Boone reviewed the entire plant with Mr. Turner. No discrepancies or violations were noted. The plant appears to be well operated and maintained. Documentation Review Mr.Turner had all required documentation for the inspection and everything was complete and current.This included discharge monitoring reports, chains of custody, laboratory records, calibration records, operator visitation records, and operation & maintenance logs. No discrepancies or violations were noted. Mr. Turner has done an excellent job of documenting his operation and maintenance of the plant. State of North Carolina I Environmental Quality I Water Resources 450 West Hanes Nfill Road,Suite 300 1 Winston-Salem,North Carolina 27105 336 776 9800 r Greystone Subdivision Wastewater Treatment Plant NCO078115 General Information The Greystone Subdivision Wastewater Treatment Plant is located off the north end of Pine Creek Road in Kernersville, Forsyth County, North Carolina, at approximate coordinates 36.167662°, 80.086436°. Aqua North Carolina, Inc is authorized to operate this 0.032 million-gallon-per-day (MGD) wastewater treatment plant, which consists of a bar screen,an influent pump station,an equalization basin,dual extended aeration basins and clarifiers,a sludge digester, tablet chlorination and dechlorination,and a flow meter,and discharge treated effluent from outfall 001 of said treatment works, which is located approximately 25 feet east of the treatment works at approximate coordinates 36.167670°, 80.086130°, to Belews Creek, which is currently classified as Class C waters and is located in the Roanoke River Basin. Site Review Mr. Boone reviewed the entire plant with Mr. Turner. No discrepancies or violations were noted. The plant appears to be well operated and maintained. Documentation Review Mr.Turner had all required documentation for the inspection and everything was complete and current.This included discharge monitoring reports, chains of custody, laboratory records, calibration records,-operator visitation records, and operation & maintenance logs. No discrepancies or violations were noted. Mr. Turner has done an excellentjob of documenting his operation and maintenance of the plant. Salem Quarters Wastewater Treatment Plant, NCO083933 General Information The WWTP is located inside the Salem Quarters subdivision in Winston Salem, Forsyth County, NC, at approximately coordinates 36.191667N, 80.109722W. The permit authorizes Aqua North Carolina Inc.to operate this 0.06 MGD WWTP,which consists of a bar screen,a flow splitter box,an equalization basin,dual aeration basins,dual clarifiers, a sand filter, an ultraviolet disinfection system, backup chlorination, contact and dechlorination system, a sludge holding tank, and standby power, and discharge the treated effluent via outfall 001 into an unnamed tributary (UT)to Belews Creek,this section of which is currently classified as Class C waters in the Roanoke River basin. Site Review Mr. Turner has done a good job operating and maintaining the plant. The only problem noted during the inspection was the presence of excessive sludge solids in the weir troughs on the effluent side of the clarifiers. It is unknown at this point what is causing the solids to accumulate in the troughs but Mr. Turner is preventing the solids from being discharged and plans to bring the effluent filters on line to filter out the solids. It is unknown when the filters will be brought on line. Mr. Boone noted no discrepancies. Documentation Review All documentation was reviewed. No discrepancixes were found. Mr. Turner has done an excellent job of documenting the operation and maintenance of the plant as required by the permit. This includes operations and visitation logs, discharge monitoring reports and laboratory and field laboratory records, chains of custody, etc. Mr. Boone noted no concerns during any of these inspections. If you have any questions regarding the inspections or this letter, please call him or me at(336)776-9800. Thank you for your cooperation in this matter. Sincerely, Sherri V.
