Box 2511 SAN 1 3 20ij Winston Salem, NC 27101 WaterQuali Pem;itting Sectior Subject: Compliance Evaluation Inspections NPDES Permits: NC0086762, Swann (Northwest) Water Treatment Plant NC0086011, Neilson Water Treatment Plant NC0079821, RA Thomas Water Treatment Plant Forsyth County Dear Mr. Hargrove: 1. 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 subject facilities on October 23, 2014. The assistance and cooperation of Bill Brewer and Kenneth Atkins was greatly appreciated. Inspection reports are attached for your records and the inspection findings are summarized below. NC0086762, SWANN (NORTHWEST)WATER TREATMENT PLANT General 2. The facility is located at 2800 River Ridge 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 Bashavia Creek, which is currently classified as Class C waters in the Yadkin Pee-Dee River basin. The wastewater treatment system consists of one equalization basin and two settling lagoons with a sodium bisulfite dechlorination 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.. Discharge monitoring records for 2013 and 2014 were reviewed and no discrepancies were noted. North Carolina Division of Water Resources,Winston-Salem Regional Office Location:585 Waughtown St Winston-Salem,North Carolina 27107 Phone:336-771-50001 FAX:336-771-4630\Customer Service:1-877-623-6748 Internet www.ncwaterquality.org An Equal Opportunity l Affirmative Action Employer Site Review 4. Filter backwash wastewater goes to the equalization basin, then to the lagoon(s), and is then discharged. The sedimentation basin blowdowns(sludge) go directly to the lagoons for settling and are then discharged. Wastewater is dechlorinated using sodium bisulfate before discharge. Decanted and dried sludge from the lagoons is land applied on site as authorized by Permit WQ0031314. The effluent flow meter was calibrated on 10/21/2014. The site was very clean and no discrepancies or violations were noted. NC0086011, NEILSON WATER TREATMENT PLANT General 5. 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 6. 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 7. Filter backwash wastewater is pumped to the eastemmost 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 eastemmost 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. NC0079821, RA THOMAS WATER TREATMENT PLANT General 8. All required records were readily available, complete, and current. Discharge monitoring reports for 2013 and 2014 were reviewed and no discrepancies were noted. Site Review 9. 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 calibrated on 9/23/2014. 10. 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) 771- 5000. Sincerely, W.
