This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0021601. 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. However, we appreciate the efforts made thus far by the Town to secure bids for replacement/repair of the clarifier weirs. This issue has been noted in the last two inspections. We hope the Town recognizes the importance of moving forward to allocate funds for this repair.

Deborah Bradley, Ronnie Pack and Christopher Cochrane were present and assisted with the inspection. Four bids have been received for replacement of the clarifier weirs. The weirs on both clarifiers are severely rusted and weir teeth are eroding in places. The Town Manager will present the bids to the Town Board at the next meeting. The ORC reports that the bids will not be awarded before July 2018. Foam at the effluent pipe should be monitored. If it persists at the level observed at the time of inspection or gets worse, operational adjustments should be made at the WWTP or with Carolina Yarn Processors. The facility appears to be well maintained and operated. Records appeared to be complete. NC0021601 17 (Cont.)
