NC0004464 I11 12I 23/09/06 117 18 i c i Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Rachel Rose and Mara Chamlee, with the Asheville Regional Office (ARO), met with Ms. Juanita James (ORC, James & James Environmental) and Hannah Turner (General Manager, James & James Environmental) for a Compliance Evaluation Inspection of the Woodland Mills WWTP on September 6, 2023. This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0004464. Overall, the facility is well -maintained and in good condition. The average flow of the facility is approximately 600 GPD in summer and 2,000-3,000 GPD during the school year. The local mill is now part of the regular flow of the facility. The following items were noted during the inspection: Operations & Maintenance: The ORC mentioned that the low lighting for the facility makes it difficult to evaluate the facility, especially in the spring/summer months. It is suggested to install additional lighting to help with proper maintenance and evaluation of the facility. Standby Power: The control panel for the WWTP does not have the correct connection requirements to be powered by a generator. A water tower is available for the school allowing for flow to still reach the plant if the power went out, so updating the control panel to be able to connect to the backup generator is suggested if funds are available. Disinfection & De -Chlorination: The solids at the beginning of the chlorine contact chamber were high. It was scheduled to have the solids wasted to the head of the plant the week after the inspection. It is suggested to have the contact chamber pumped or wasted soon if it is not already done.
