NCO068799 I11 12I 23/11/30 117 18 i c i Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Rachel Rose, Lauren Armeni, and Mara Chamlee, with the ARO Regional Office (ARO), met with Juanita James (BORC, James & James Environmental), Hannah Turner (General Manager, James & James Environmental), and Jeff Singleton (Maintenance Tech, James & James Environmental) to conduct a Compliance Evaluation Inspection on November 30, 2023 for the Greystone Subdivision WWTP. This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0068799. The following items were noted during the inspection: Operations & Maintenance: There was significant rusting of the grating throughout the facility, especially the grating between the aeration basin and digester. It is suggested to replace the grating for the safety of the workers. Secondary Clarifier: The floating solids seemed excessive at the time of the inspection, however, the skimmer is turned on manually by the ORC and had not yet been turned on for the day at the time of the inspection. When it was turned on briefly during the inspection, the skimmer was working and the top layer of solids was clearing up efficiently. Effluent Pipe: The right of way needs to be maintained to allow for regular observation of the effluent pipe. Standby Power: The control panel for the WWTP does not have the correct connection requirements to be powered by a generator and there is no generator currently available. The subdivision is on city water which allows for flow to reach the WWTP if the power went out, so updating the control panel to be able to connect to a portable backup generator to have a form of standby power available is suggested if funds are available.
