Regional Supervisor Water Quality Regional Operations Section Raleigh Regional Office Division of Water Resources, NCDEQ SUBJECT: NOV Letter Response Tracking Number: NOV-2019-PC-0662 Permit No. WQCS00294 Mr. Bolick: NC Dept of Environmental Quality (-Jr r z 8 2019 Raleigh Regional Office The Town of Selma has and is taking immediate action to resolve issues that contributed to an SSO at the Johnston County Lift Station on September 7, 2019 during Hurricane Dorian. Since Hurricane Florence, the Town of Selma has experienced an extreme increase of Inflow and Infiltration (1&1) into the Town of Selma sewer system. On April 171h, 2019 the Town of Selma reached out to WithersRavenei for assistance identifying potential sources of I&I.On May 10, 2019 the Town pursued a Golden LEAF Disaster Recovery (GLF-DR) grant to study the effects of Hurricane Florence on the sewer system. The Town was awarded a GLF-DR grant of $142,000 to study the sanitary sewer impacts of Hurricane Florence on June 6, 2019. Contracting began shortly after and work began immediately on the GLF-DR Sanitary Sewer Evaluation and Study (SSES) Project. (Application documents provided shared Dropbox). The Tasks associated with the GLF-DR grant area as follows: Task 1-- Surveying Services 1.1 — Data Acquisition (Complete) 1.2 — GPS Manhole Locations and Internal 360 degree photography (Complete) 1.3 — GIS connectivity and QC (Complete) Task 2 — Flow Monitoring (Scheduled for November) Task 3 — Smoke Testing (Complete) Task 4 — Report (Preliminary Draft Complete - Pending Flow Monitoring) All documents associated with the GLF-DR SSES Project are included as supporting information with this letter. Upon completion of smoke testing, the Town identified a multitude of missing clean out caps in low lying areas that were contributing I&I to the system. All of the caps have been repaired and a clean out cap education program is being developed to inform the public of the importance of keeping storm water out of the sewer system. 114 N. Raiford Street - Selma, NC 27576 - P: (919) 965-9641 - F: (919) 965-4637 - www.selma-nc.com Other areas of major I&I entry that were identified are associated with storm drainage inlets. One area showing signs of extreme I&I was determined to be eligible for potential CDBG-I funding. An application was developed and submitted on September 30, 2019. If funded, the CDBG-I project would rehabilitate/replace approximately 6,505LF of sewer and rehabilitate / replace 33 manholes. (Application documents provided shared Dropbox). Additionally, an amendment to the GLF-DR application was submitted on October 18, 2019 requesting $824,370 to rehabilitate / replace 3,990LF of gravity sewer in five (5) different locations associated with storm drainage failures attributed to Hurricane Florence. The Town of Selma is hopeful this funding will be made available and repair to this portion of the sewer system could begin within a few short months. (Application documents provided shared Dropbox). To support the modification of the GLF-DR grant, the Town of Selma has begun to CCTV gravity sewer mains that are likely candidates of extreme I&I based on age, material, and smoke testing results. Some of the video captures are included with the letter. (Application documents provided shared Dropbox). The Town of Selma is taking all necessary steps to reduce the I&I issues that have occurred since Hurricane Florence. The Town of Selma is experiencing approximately $720K of additional annual sewer treatment costs as a result of the sudden increase of I&I. This increase in operational expense further complicates the ability to resolve issues. The lack of resources has been a driving force to identify funding opportunities to resolve very costly repairs. In addition, the Town of Selma has limited personnel and capability to complete repairs. Lastly, the Town of Selma recently replaced their Interim Town Manager and Interim Public Works Director with permanent replacements. With the addition of permanent staff in key leadership positions, the Town of Selma can now set a long-term vision on how to address the I&I issues for the next decade. The Mayor and Town Council are committed to resolve the sewer issues. The Mayor, Town Council, and staff are actively engaged together to identify immediate reductions in I&I and to develop a sustainable path forward for the large capital projects that will be required for years to come. The Town of Selma welcomes the opportunity to discuss any of our current and future plans to reduce I&I in greater detail with all stakeholders. We are hopeful that this response to the NOV letter demonstrates the Town of Selma's commitment to resolving these issues and prevent a future SSO.
