Beckford Drive Henderson, NC 27536-1434 Phone: (252) 431-6030 / Fax: (252) 431-0124 February 14, 2022 Mr. Scott Vinson, Regional Supervisor Water Quality Regional Operations Section Raleigh Regional Office Division of Water Resources, NCDEQ 1628 Mail Service Center Raleigh, NC 27699-1628 Re: Response to Notice of Violation & Intent to Issue Civil Penalty Tracking No. — NOV-2022-DV-0019 Sanitary Sewer Overflows — December 2021 Henderson Collection System Permit No. — WQCS00055 Dear Mr. Vinson: I am writing in response to the above -mentioned violation that we received on February 1, 2022. The overflow in Incident Number 202102215 was due to rags/paper towels in the sewer main. While checking our sewer outfalls, aerials line, sewer flow, etc., our crews discovered the creek was unusually dirty along our Hugh's Farm Outfali. Further investigation led us to manhole HEND-26-MH-038 near Ranes Drive which was surcharging. We used our tow behind jetter to clear a blockage in the downstream sewer main. Once the blockage was cleared the SSO subsided, and flow returned to normal. Once the blockage was cleared, we damned the creek roughly 2000 feet downstream of the SSO. We placed a pump in the creek and pumped water from the creek into a nearby manhole at a rate of approximately 400 gpm for 4 hours. In addition to pumping the creek, we introduced clean water from a fire hydrant into the creek upstream at approximately 400 gpm for 4 hours. Crews walked the creek to clean and rake as needed. We placed 50 pounds of lime around the manhole that surcharged. No fish were killed and oxygen levels in the creek were normal. We take our responsibility to maintain compliance for our collection system very seriously. Our efforts in stopping and mitigating this sewer overflow has already cost the city over $4,600. I respectfully request that the City be allowed to dedicate our funds to the maintenance and operation of our sewer collection system rather than paying fines. I trust that you find the City's actions for compliance are satisfactory. Thank you very much for the opportunity to respond. Please feel free to contact our staff or myself should you need any further information.
