Dear Mr. Tharrington,
On behalf of Carolina Water Service, Inc. of NC (CWSNC), please accept this letter in response to the
Belvedere Plantation Wastewater Treatment Facility (Permit Number WQ0001664) Notice of Violation,
Tracking Number NOV-2024-LV-0289.
On April 10, 2024, Carolina Water Service, Inc. of NC received a notice of violation for total nitrogen
monthly average exceedance, reporting violation for chloride, and reporting violation for total dissolved
solids.
The cause of the monthly average total nitrogen exceedance remains unknown. To ensure future
wastewater treatment effluent compliance staff has diligently focused on various aspects of the wastewater
treatment plant processes. These include monitoring activated sludge wasting rates, aeration dissolved
oxygen (D.O.) levels, anoxic zone D.O. levels, and activated sludge recirculation rates. As a result of
increased vigilance, there has been a significant reduction in total nitrogen effluent discharges. Notably, the
total nitrogen effluent complied with regulations for December 2023, January 2024, and February 2024.
Additionally, chloride and total dissolved samples were collected. Unfortunately, these sample results were
inadvertently omitted from the National Pollutant Discharge Elimination System (NPDES) Discharge
Monitoring Report (NDMR). However, the missing data has now been included, and the NDMR report has
been resubmitted. Moving forward, the staff will exercise extra caution to prevent any reporting violations in
future reports.
If you need additional information, please feel free to contact me at 312-965-3728, or by email at
