Ron Boone of the Winston-Salem Regional Office of the NC Division of Water Resources (DWR or the Division) conducted compliance evaluation inspections (CEI) at the Neilson and RA Thomas water treatment plants on November 13, 2015. The assistance and cooperation of Bill Brewer, Rodney Darr, and Kenneth Atkins was greatly appreciated. Inspection reports are attached for your records and the inspection findings are summarized below. NCO086011, NEILSON WATER TREATMENT PLANT General 2. The facility is located at 5725 Frye Bridge Road, in Winston Salem, Forsyth County, North Carolina. The facility is authorized to discharge wastewater from the treatment works through outfall 001 to an unnamed tributary (UT) of Muddy Creek, this section of which is currently classified as Class C waters in the Yadkin Pee -Dee River basin. However, the wastewater treatment system does NOT discharge. All wastewater is recycled through two wastewater treatment lagoons and one of the raw water reservoirs. The wastewater is then treated through the potable water treatment system. The waste stream consists of backwash water from the water treatment system's filters and sludge from the water treatment system's sedimentation basins. Documentation & Monitoring Review 3. All required records were readily available, complete, and current. There are no DMRs for review. The plant currently has a waiver from submitting monthly DMRs because the plant recycles all wastewater and there is no discharge. The waiver is in effect until the plant begins discharging again. Site Review 4. Filter backwash wastewater is pumped to the easternmost raw water reservoir. Sedimentation basin blowdowns (sludge) go to one of three waste lagoons and decant from that sludge is then also pumped to the easternmost raw water reservoir. All wastewater is recycled through this process and then back through the potable water treatment system. As stated above, there is currently no discharge from the waste treatment system. Decanted and dried sludge from the waste lagoons is land disposed on the "Cooper Road Disposal Site", which is located a few miles from the water treatment plant. The site was very clean and no discrepancies or violations were noted.

RA THOMAS WATER TREATMENT PLANT General 5. All required records were readily available, complete, and current. Discharge monitoring reports for 2015 were reviewed and no discrepancies were noted. Site Review 6. Filter backwash wastewater goes directly to the equalization basin, then to the clarifier. The treated effluent from the clarifier goes to a flume where it is measured and discharged. The sludge from the clarifier goes to the waste lagoons. Sedimentation basin blowdowns (sludge) go directly to the waste lagoons: Decant from the waste lagoons goes to the equalization basin, then to the clarifier. The effluent flow meter was last calibrated on September 16, 2015. 7. Please encourage your operators to continue their outstanding efforts in complying with all permit conditions. Should you have any questions, please feel free to contact Mr. Boone or me at (336) 776-9800. Sincerely, Sherri V. Knight Asst.
