This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0075353. We met with Juanita James (Owner of James & James Environmental) for the inspection. Rick Swilling (ORC) was not present due to concerns with COVID-19. Overall, the plant seemed to be operating well. The structural integrity of the plant should continue to be closely monitored as the facility is beginning to show age-related corrosion and may need to be painted. The following are recommendations pertaining to the inspection findings: 1. There's a leak in the return sludge pipe which needs to be fixed. 2. The structural integrity of the plant should continue to be closely monitored as the facility is beginning to show age-related corrosion and may need to be painted. 3. The chlorine contact chamber contained solids which will need to be pumped out. 4. The currently sampling location is not ideal for ease of sampling and should be assessed further during any future plant upgrades. Perhaps once the outfall access is maintained the sampling could occur there. 5. The effluent pipe could not be accessed. Please maintain the right of way to the outfall. NC0075353 17 (Cont.)
