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

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.
