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 Hasentree WWTP, Wake County Permit No. WQ0021934 NOV-2024-LM-0069 Dear Ms_ Manuel: Aqua North Carolina, Inc. (Aqua) offersthe following response to the above -referenced Notice of Violation for Nitrogen, Ammonia Total (as N) daily and monthly exceedance and pH frequency violation, found in the March 2024 Non -Discharge Monitoring Report. Agua's Response: In reference to the above NOV for the Ammonia exceedance, staff investigated the plant process and could not determine a root cause for this excursion. All additional sampling has been within compliance. The pH reading was recorded the day in question but was unintentionally left off the non -discharge monitoring report. The pH reading of 7.6 was documented on 3/18/24 in the logbook at the WWTP. Attached please find the March 2024 revised NDMR which was mailed into the State on 9/12/24. Aqua respectfully requests that the monitoring frequency violation for the pH reading be rescinded. If you have any questions or comments, please do not hesitate to contact me at (919) 653 - 5776.
