This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0069370. 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 violation(s) were noted during the inspection: Inspection Area Description of Violation _________________________________________________________________________________________________________________________________________________________________________ Pump Station - Effluent The alarms were not working. _________________________________________________________________________________________________________________________________________________________________________ Pump Station - Influent The audio and visual alarm at the influent pump station were not working, but the autodialer was working. One of the high water floats seemed to be missing. _________________________________________________________________________________________________________________________________________________________________________ Aerobic Digester The digester is full and the ORC is not able to waste solids from the aeration basins until the digester solids are pumped out. _________________________________________________________________________________________________________________________________________________________________________ DocuSign Envelope ID: FE06291E-763D-409B-B331-BBF69F79A7F5 Inspection Area Description of Violation _________________________________________________________________________________________________________________________________________________________________________ Secondary Clarifier There was only about 0.5 feet of clear supernatant in the clarifier. The sludge blanket was sitting only about 1 foot below the water surface. _________________________________________________________________________________________________________________________________________________________________________ Additional explanation about these violations: Please thoroughly review the process and current state of the WWTP described below, as it illustrates the need for immediate corrective action. An activated sludge WWTP grows bacteria sludge in the aerations basins. These bacteria are fed by and treat the organics in the sewage coming into the WWTP. To keep the amount of bacteria in the aeration basins at a stable level, a certain portion of the sludge must be “wasted” into a sludge digester. When the sludge digester becomes full, it needs to be pumped out to allow continued wasting from the aeration basins. If wasting stops the sludge begins to thicken in the aeration basins and fill the clarifiers (settling basin). If the solids spill out of the clarifier and into the WWTP effluent (which discharges to the creek), then the WWTP is violating its permit and polluting surface waters. When I conducted my inspection of the WWTP, the settleable solids in the aeration basin measured 98%, which is extremely high, and indicates to me that the WWTP is at risk of discharging its solids through the effluent. To remediate this situation, sludge solids need to be pumped from the WWTP as soon as possible. The Division of Water Resources may pursue enforcement action for this and any additional violations of State law. To prevent further action, please respond in writing to this office within 30 days upon your receipt of this Notice of Violation regarding your plans or measures to be taken to address the indicated violations and other identified issues, if applicable. If you should have any questions, please do not hesitate to contact Daniel Boss with the Water Quality Regional Operations Section in the Asheville Regional Office at 828-296-4500. Sincerely, G.
