The facility is located at 1620 Fred Hinshaw, Road, in Yadkinville, Yadkin County, North Carolina. The facility is authorized to discharge treated wastewater from the treatment works through outfall 001 to North Deep Creek, which is currently classified as Class WS -IV waters and is located in the Yadkin Pee - Dee River basin. The wastewater treatment system consists of a mechanical bar screen, dual grit removal facilities, an influent pump station, an equalization basin, a flow splitter box, aeration basins, an oxidation ditch, secondary clarification, chlorine contact chamber utilizing gas chlorination, gas dechlorination using Sulfur Dioxide, aerobic sludge digestion, sludge drying beds, and standby power. Documentation & Monitoring Review 3. The inspection was truncated to a site inspection only due to the inspectors limited time availability. However, he did conduct an in office review of all available records and no discrepancies were noted. Site Review 4. The plant was very clean and well maintained. The effluent flow meter was last calibrated in September, 2016 and is due to'be calibrated in December sometime. The effluent appeared clear and of high quality. Mr Trivette and his operations staff appear to be doing an outstanding job of operating and maintaining the facility.
