This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0033227. A summary of the findings and comments noted during the inspection are provided in the enclosed copy of the inspection report. The Compliance Evaluation inspection was conducted by Division of Water Resources staff from the Asheville Regional Office. The following deficiencies were noted during the inspection: Inspection Area Description of Deficiency Operations & Maintenance Influent overflowed/splashed over plant. Plant is high in solids. Secondary Clarifier The blankets in the clarifier were too high at 7'and 8' of 10' water depth. Solids need to be removed. Plant needs to be able to waste solids. North Carolina Department of Environmental Quality I Division of Water Resources 2090 U.S. 70 Highway, Swannanoa, NC 28778 828-296-4500 DocuSign Envelope ID: D5FD430A-CE20-4570-A397-E3FCDAB74CD6 Inspection Area Description of Deficiency Bar Screens The bar screen had excessive debris allowing influent to spill out of plant onto adjacent ground. Effluent Pipe The streambank at the domestic wastewater effluent pipe (#I) has eroded from recent storms and compromised the effluent pipe and its structure. In addition, the issues below must also be addressed: Compliance Issues: Unknown Plumbing: The WWTP appears to possibly have plumbing for wasting solids (WAS). There is also an unknown pipe in the chlorine contact chamber. This possible WAS plumbing and the unknown pipe in the chlorine contact chamber need to be assessed and verified. Remedial actions should have already been taken to correct this problem and prevent further occurrences in the future. Please submit a written response to this Notice of Deficiency. Your response is to be received by the regional office within 30 business days following receipt of this Notice. If you should have any questions, please do not hesitate to contact Linda Wiggs with the Water Quality Regional Operations Section in the Asheville Regional Office at 828-296-4500.

NC0033227 I11 121 18/11/07 117 18 ICI Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) The Inspector, Linda Wiggs, met with Jason Rummel (ORC) and Doug Dodd (EHS Mgr) onsite. BAR SCREEN: The bar screen had excessive debris. The bar screen is at the water level of the aeration tank and the return solids (RAS) are deliver next to the bar screen. All these issues appear to contribute to the influent spilling/splashing out of plant onto the adjacent ground. An email was received by the Inspector on 11/8/2018 with photos verifying a temporary splash guard was installed to keep wastewater from spilling/splashing over. SOLIDS: The plant was high in solids. Settleability at 30 minutes was 850 ml. The blankets in the clarifier were 7'and 8' of 10' water depth. Solids need to be removed promptly. The log book indicated solids had been pumped in March and July. This WWTP does not have a digester, there is no tank to waste sludge/solids (WAS). However, the WWTP appears to have plumbing for WAS. This plumbing needs to be assessed and its use verified. Tankage (digester) where solids can be sent for removal is a crucial component of a WWTP. The addition of a digester needs to be given serious consideration. CHLORINE CONTACT CHAMBER: There is a large buried tank used as a chlorine contact basin; this basin has an unknown pipe in it. The unknown pipe's origin and destination need to be verified. The original Plans of this WWTP and any ancillary components should be researched. EFFLUENT PIPE: The streambank at the domestic wastewater effluent pipe (001) has eroded from recent storms and compromised the effluent pipe and its structure. This is a safety issue and has compromised the effluent sampling location. Furthermore, the next high flow storm event could break the effluent pipe and dislodge the structure.
