The sanitary sewer overflow occurred during an intense rain event while antecedent wet weather conditions had failed to diminish. Incident 202400591 referenced in this NOV was published in a press release pursuant to NCGS 143-215.1C(b)(1). Attached are images of radar from the storm as it passed through North Carolina on March 6, 2024. Also attached is an image of radar from another strong storm as it passed through North Carolina less than a week prior to this SSO. This chronic spill site arises from high inflows into the Belmont Pump Station located in sub -basin `A' of the collection system. Peak wet weather flows to the Belmont Pump Station occasionally exceed the pumping capacity in the existing pumps and when the pump station runs frequently the downstream gravity sewer becomes surcharged and is at risk for overflows in several shallow manholes. On March 15, 2023, RRSD received a Belmont Pump Station Preliminary Engineering Report from Freese and Nichols, Inc. which recommended increasing the pumping capacity at the pump station along with rerouting the force main to a larger gravity line downstream with more capacity. On September 29, 2023, RRSD submitted a Belmont Pump Station Improvement Project Application for Funding to NCDEQ Division of Water Infrastructure requesting a funding amount of $2,859,165. We are confident this Page 1 of 2 project will eliminate the upstream and downstream surcharging this pump station is causing. On February 20, 2024, we learned this funding request was not awarded. On April 10, 2024, RRSD purchased adjacent property to the existing Belmont Pump Station. Our intent is to construct a new pump station on the newly acquired property. On April 30, 2024, RRSD submitted a Belmont Pump Station Improvement Project Application for Funding to NCDEQ Division of Water Infrastructure requesting a total funding amount of $3,405,937. Also on April 30, 2024, RRSD issued a purchase order to Freese and Nichols, Inc. to begin design services on the new Belmont Pump Station and force main. We are diligently pursuing other funding opportunities for this project while optimizing pump station operations. We trust our actions are deemed adequate and prudent. Roanoke Rapids Sanitary District greatly appreciates your time and consideration in this matter. Should you require additional information, please do not hesitate to contact us. Sincerely, Thomas C.
