ROCERS, JR. Director NORTH CAROLINA Environmental Q¢aflry SENT VIA ELECTRONIC MAIL ONLY: NO HARD COPY WILL BE MAILED. October 4, 2022 Wilson Hooper, City Manager City of Brevard E-mail: Wilson.Hooper@cityofbrevard.com SUBJECT: Compliance Inspection Report Brevard WWTP NPDES WW Permit No. NC0060534 Transylvania County Dear Permittee: The North Carolina Division of Water Resources conducted an inspection of the Brevard WWTP on 10/03/2022. This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0060534. The findings and comments noted during this inspection are provided in the enclosed copy of the inspection report entitled "Compliance Inspection Report". The following items were noted during the inspection: •The facility experiences high annual chemical usage due to the limitations of its biological treatment capacity. An assessment of alternative and/or expanded biological treatment options is being assessed for future upgrades. Continue to keep ARO informed on this process. •The backup generator appears to be near the end of its service life, and replacement should be evaluated. •The Chemical Feed Building was being renovated at the time of the inspection and bulk chemical tanks were temporarily stored outside. It is recommended that this project be finished, and the tanks moved back inside prior to the onset of winter. •The EQ tank cannot be completely emptied and cleaned due to accumulation of debris/solids from the collection system and potential for fouling of treatment components. It is recommended that macerator pumps be installed to address this issue when conveying water back to the treatment train. •It is recommended that the Pretreatment Coordinator attend the annual NC Pretreatment Consortium on a regular basis for training and continuing education opportunities.

Emory Owen (ORC) and Tom Williams (Pretreatment Coordinator and Lab Manager) were present and assisted with the inspection. The facility appeared well operated and maintained at the time of the inspection, and in compliance with Permit NC0060534. The following additional items were noted at the time of the inspection: The facility experiences high annual chemical usage due to the limitations of its biological treatment capacity. An assessment of alternative and/or expanded biological treatment options is being assessed for future upgrades. Continue to keep ARO informed on this process. The backup generator appears to be near the end of its service life, and replacement should be evaluated. The Chemical Feed Building was being renovated at the time of the inspection and bulk chemical tanks were temporally stored outside. It is recommended that this project be finished, and the tanks moved back inside prior to the onset of winter. The EQ tank cannot be completely emptied and cleaned due to accumulation of debris/solids from the collection system and potential for fouling of treatment components. Its is recommended that macerator pumps be installed to address this issue when conveying water back to the treatment train. Pump trucks hauling sludge from package plants and water treatment facilities are currently being emptied into the digester to reduce the biological load on the treatment train and reduce chemical costs. It is recommended that the Pretreatment Coordinator attend the annual NC Pretreatment Consortium on a regular basis for training and continuing education opportunities. The Pretreatment Coordinator reported a continued good working relationship and communication with the single SIU: Oscar Blues Brewery.
