Manuel, Assistant Regional Supervisor Water Quality Regional Operations Section Raleigh Regional Office, Division of Water Resources, NCDEQ 3800 Barrett Drive Raleigh, NC 27609 Re: Notice of Violation & Intent to Assess Civil Penalty Neuse River Village WWTP, Wake County Permit No. NC00387S4 NOV-2023-LV-0693 Dear Ms. Manuel: Aqua North Carolina, Inc. (Aqua) offers the following response to the above -referenced Notice of Violation and Intent to Assess Civil Penalty, for the daily maximum for Fecal Coliform, from the August 2023 Discharge Monitoring Report. Anua's Response: The WWTP disinfection system was operating properly at the time of these excursions. The post -treatment pond is consistently battling natural influences such as algae growth and temperature changes and the results are not a true representation of the treatment plant's effluent quality. Aqua has hired an outside engineer, Black and Veatch, to assist in the process of conducting preliminary testing and evaluations of the existing WWTP in order to determine the root cause of the solids settling issues. A preliminary site investigation has been conducted and 5 days of water quality sampling will be conducted in the next 2 weeks. After the lab results return, B&V will model the plant and draft a technical memo outlining issues and recommendations for rehab. Initial thoughts are installing tertiary filtration after the clarifiers and re - purposing the settling pond as an upset pond to provide more EQ storage. If you have any questions or comments, please do not hesitate to contact me at (919) 653-6982. Sincerely, Robert Krueger Area Manager cc: Joseph Pearce PE Shannon Becker
