The facility operates under NPDES permit #NC0033111. The facility was found to be compliant with permit #NC0033111. The facility was inspected due to a complaint filed against the facility by residents nearby the facility. There was complaint was that there of an overwhelming odor issue and noise issue with the blowers. Upon inspection of the facility, there was no odor issue to be found and the blowers were no louder than ones found at the average facility. The facility has an emergency fuel agreement with Mallard. All required records were present for review, and all were maintained well over 5 years. The April 2021 DMR was spot checked vs corresponding lab data. Only a minor issue was found on the third week of the month where Total N was reported as 22.63mg/I vs the 22.56m1/I that was reported on the lab data. After a small review with ORC Mathew Golden, this was found due to a small rounding error. No other issues were found on the April 2021 DMR. The sludge blanket for clarifier 1 was 5ft and 4.5ft in clarifier 2 and this was measured via sludge judge. It is important to note both clarifiers have a sidewall depth of 14ft. Another issue noted with the clarifiers where the skimmer arms in one of the units did not touch the water and was in need repair. The skimmer arm for the clarifier was fixed the next week and a video of the fix was sent on 08/04/2021 via email. During the inspection the Eluent flowmeter was found to be last calibrated over 3 years ago on 01/01/2018. It was discussed with the ORC that the effluent flowmeter had to be calibrated annually. ORC Golden Mathew followed up 2 days later and showed that he had the effluent flowmeter calibrated on 07/28/2021.
