JAY ZIMI ERMAN Dimdar RECEIVED/NCDE0/0WR AUG 0 9 2017 Water Quality Permitting Section Subject: Compliance Evaluation Inspection Report NPDES Permit NCO060259 Willow Oak Mobile Home Park WWTP, Rockingham County Dear Mr. Radford: 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 a bar screen, facultative lagoons and alum feed tanks. 2. Facility Site Review The facility was as described in the permit. Flow is low compared to the permitted amount (permitted for 22,000 gpd; average reported flow over the last 2 years is about 150 gpd). 3. Operation and Maintenance The operator or a properly designated backup visits the site as required. Visitation logs were current and available during the inspection. The 4th chamber of the alum feed system was observed to be leaking on the lagoon -facing side. A follow-up visit was conducted on July 31 to verify that the leak had been plugged, but the ORC mentioned additional maintenance may be needed. State of North Carolina 1 Environmental Quality I Water Resources dan m t w-- &NI Rnad Nuite 40n Wmetnn-.Salem. NC 27105 A.. 4. Flow Measurement The permit requires instantaneous flow measurement influent or effluent. Flow is measured at the influent. 5. Effluent/Receiving Waters The effluent is discharged into Little Troublesome Creek. The outfall was not accessible during the inspection due to the lack of a path and swampy ground. Documentation Review 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 no violations. A comparison of submitted DMR data with bench sheets did reveal one minor error on the August, 2016 DMR. Mr. Smith said he would more carefully check that the data has been transferred correctly before submittal. 8. 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. 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, Sherri V.
