Snider, Assistant Regional Supervisor Water Quality Regional Operations 450 West Hanes Mill Road, Suite 300 Winston-Salem, North Carolina 27105 Dear Mr. Snider, This letter is in response to the Notice of Violation and Recommendation for Enforcement Letter dated July 11, 2022 received by the City of Greensboro. The address where the violation occurred and the amount spilled is shown below: 1. 1881 Mayfair Avenue 3000 Gallons The sanitary sewer release at 1881 Mayfair Avenue on May 1, 2022, was due to debris accumulation in the sanitary sewer at this address. A combination jet truck was dispatched to unstop the blockage and clean the line. Once the sanitary sewer overflow was stopped, we thoroughly cleaned all lines in the area to ensure we could perform a CCTV inspection of the line to see if further action would need to be taken to prevent future debris accumulation. Upon our CCTV inspection, we found a heavy presence of "flushable wipes" that the residents are using. To combat this current trend, we produced and distributed public notices via social media and television on the effects that wipes have on the collections system to help prevent future accumulation. The line is now on a biannual PM schedule, and we will monitor the line to see if that cycle needs to be increased in the future. Remediation efforts include opening fire hydrants to flush the affected area, and we spread lime to minimize the spill's impact. It is our duty to comply with the requirements of Collection System Permit Number WQCS00006 and G.S. 143-215.1(a)(1), and we will continue to address unforeseen circumstances as quickly as they occur. If any additional information is required, please do contact me. We appreciate your review and welcome your feedback.
