Box 326 RECEIVED/DENR/DWR Boonville, NC 27011-0326 SUBJECT: Compliance Evaluation Inspection MAY 5 2015 Boonville Wastewater Treatment Plant Water Quality NPDES Permit: NC0020931 Permitting Section Yadkin County Dear Mr. Hunter: Ron Boone of the Winston Salem Regional Office(WSRO)of the North Carolina Division of Water Resources (DWR or the Division) conducted a compliance evaluation inspection of the Boonville Wastewater Treatment Plant on April 14, 2015. The assistance and cooperation of Jeff Jones, Operator in Responsible Charge (ORC), was greatly appreciated. An inspection report is attached for your records and the inspection findings are summarized below. The Boonville Wastewater Treatment Plant is located at 456 Lon Avenue, at approximate coordinates 36.246177°, -80.707273°, in Boonville, Yadkin County, North Carolina. The Town of Boonville is authorized to operate this 0.2 million-gallon-per-day (MGD) wastewater treatment plant, which consists of a bar screen, splitter box, comminutor, aeration basins,secondary clarifiers, UV disinfection,digesters, sludge drying beds, and flow measurement, and discharge treated effluent from outfall 001 of said treatment works, which is located approximately 250 feet east of the treatment works at approximate coordinates 36.246536°, -80.706452°, into Tanyard Creek, which is currently classified as Class C waters and is located in the Yadkin Pee-Dee River Basin. SITE REVIEW Mr. Boone reviewed the entire plant with Mr. Jones. Everything was in good condition and well maintained. The effluent was clear and there was no foam at the discharge point into Tanyard Creek. The discrepancies Mr. Boone noted are as follows: 1. The plant does not have a field laboratory certification. A certification must be acquired for the plant to run dissolved oxygen, pH, and temperature analyses themselves. Please go to the following website to initiate this process: http://portal.ncdenr.orq/web/wq/lab/cert 2. Influent sampling is not flow proportional as required by the permit. There is no influent flow meter. The Town may wish to request exemption from this requirement from the Division.
