REOAN u91#0P fttiirV JAY ZIMMERMAN Dkertor On July 17, 2017, Paul DiMatteo of the Division of Water Resources ("Division"), Winston-Salem Regional Office conducted a Compliance Evaluation Inspection of the above referenced wastewater treatment system. Paul Smith, Operator in Responsible Charge (ORC), was present for the inspection. An inspection summary follows and an inspection report is attached for your records. Site Review 1. Permit The current permit became effective on July 1, 2016 and expires on April 30, 2021. A copy of the current permit was not available for review — one should be kept for inspection. Permitted components include an aeration basin, clarifier, and chlorine disinfection. 2. Facility Site Review The facility was as described in the permit. 3 Operation and Maintenance The high-water alarm in the influent tank was not operational. The facility appeared to otherwise be well maintained. The operator or a properly designated backup visits the site as required. Visitation logs were current and available during the inspection. Please have the high-water alarm repaired by the next inspection. 4. Flow Measurement Flow is measured using a V -notch weir. The weir did not appear to be obstructed. 5 Effluent/Receiving Waters The outfall could not be accessed during the inspection. A cleared path to the outfall is not maintained. State of North Carolina I Environmental Quality I Water Resources ecn TV— u_- l.f.11 A.,.,.7 q, m snn W' 777n5 Documentation Review I; 6. Records/Reports Discharge Monitoring Reports (DMRs) and lab data are maintained according to the permit. DMRs include all permit parameters. Copies of DMRs, operator visitation logs, lab reports and Chain -of -Custody forms were available for review during the inspection. 7. Self -Monitoring Program A review of DMRs from May, 2016 through May, 2017 showed the following violations, which have been addressed in previous correspondence from this office: PARAMETER VIOLATION DATE VIOLATION ACTION Nitrogen, Total - Concentration 03/31/2017 Proceed to NOD Phosphorus, Total (as P) - Concentration 03/31/2017 Proceed to NOD Phosphorus, Total (as P) - Concentration 06/30/2016 Proceed to NOD Coliform, Fecal MF, MFC Broth, 44.5 C 07/19/2016 Proceed to NOV Solids, Total Suspended - Concentration 11/30/2016 Proceed to NOD A comparison of submitted DMR data and field records showed no errors or concerns. Laboratory Field parameters are measured by the ORC under certification # 5169 (Smith Industries). All effluent samples are taken from the aerobic digester. All other parameters are measured by Pace Analytical under certification # 633. Chain -of -custody forms were complete and available for all parameters measured off site. Records for parameters measured on-site were complete. 9. Sludge Handling Disposal Sludge is removed from the plant as needed. We appreciate your efforts in effectively operating and maintaining this treatment system. No additional response to this report is required. If you should have any questions, please do not hesitate to contact Paul DiMatteo at (336) 776-9691 or our office at (336) 776-9800. Sincerely, ft,/Sherri V.
