Director Stephen Glenn Morgan Moore County 425 Edward Rd Star, NC 27356 NORTH CAROLINA Environmental Quality April 7th, 2022 SUBJECT: Compliance Inspection Report Moore County WPCF NPDES WW Permit No. NC0037508 Moore County Dear Permittee: The North Carolina Division of Water Resources conducted an inspection of the Moore County WPCF on 2/15/2022. This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0037508. The findings and comments noted during this inspection are provided in the enclosed copy of the inspection report entitled "Compliance Inspection Report". There were no significant issues or findings noted during the inspection and therefore, a response to this inspection report is not required. Inspection Summary The Moore Co. WPCF is a 10MGD, grade 4 facility. The facility's grounds and laboratory were well - maintained. Stephen Morgan and Connie Flowers accompanied DEQ staff during the inspection. Records were available for review and were found to be accurate. The facility submitted a permit renewal application on 3/29/2021. We note that staff make a copy of each newly completed page of the ORC log on a monthly basis. A bound book is another option for a ORC log. Back-up ORC Jeremy Monroe will be removed and replaced with James Newman (Grade 4 WW). DMRs for Aug. and Feb. 2021 were reviewed. Reports were free of errors and records were complete. The facility contracts with Meritech Labs but will switch to Environment One in June. Three out of four influent pumps are operational. One pump is currently being repaired. Headworks alarm testing records are stored in the ORC's office. The facility has three back-up generators. Testing is conducted regularly. Records are stored in the ORC's office. Influent sampling occurs for process control D_E North Carolina Department of Environmental Quality Division of Water Resources Fayetteville Regional Office 1225 Green Street. Suite 714 I Fayetteville, North Carolina 28301 910.433.3300 only and is time -based. Copious biofilm was observed in the sampler tubing. The temperature inside the refrigerated sampler cabinet at the influent and effluent was approximately 0°C. Contents of the debris dumpster are disposed of once per day. Grit dumpsters are emptied every 1-2 days. One primary clarifier was out of service for the season. Sludge blanket was approximately 1 ft. Sludge blanket was approximately 4 in. in the secondary and tertiary clarifier. DO levels in both aeration basins averaged —2.0 mg/I. Lime slurry is added to the second stage basin to adjust pH. One chamber in the second stage basin was offline for valve replacement. Flow meters are calibrated twice annually. The last calibration occurred on 8/4/21 and is scheduled for 2/16/22. There are six total sand filters. One filter was down for media replacement at the time of the inspection. Transmittance in the UV disinfection array was —65%. Replacement bulbs are kept in a secure storage shed next to the UV array. Sludge is hauled to the Anson Co. landfill. Drying beds are only used in emergencies. Samples for permit compliance were collected at Outfall 001 from Moore Co. WPCF's 24-hour composite equipment on February 15th, 2022. Parameters sampled were BOD, TSS, fecal coliform, and nutrients (ammonia, NO2/NO3, TKN, and TP). These samples were submitted to the Division of Water Resources Laboratory in Raleigh, NC. Table 1.
