As graciously requested in the letter, the following evidence and justification demonstrates that these events were exceptional, unintentional, temporary, and beyond reasonable control of the utility. This evidence will also establish the significant costs and actions taken to stop the discharge; contain the release of untreated wastewater; collect the wastewater, and restore any possible environmental impacts. Further, it demonstrates the City of Durham Department of Water Management's (DWM) strong commitment to and investment in preventing and mitigating sanitary sewer overflows (SSO). All conditions of the City's Collection System permit are met by the Department, including system cleaning, site visits, inspections, and easement maintenance. As such, we respectfully request that no civil penalties be assessed for the SSOs that occurred in the City's wastewater collection system between May 1, 2024 and May 31, 2024. Incident##202400846 — May 1, 2024 — 400 Muldee Street On May 1, 2024 at 12:08 PM, an overflow occurred near 400 Muldee Street releasing an estimated 860 gallons of wastewater into a tributary of Eilerbe Creek. Crews discovered that vandalism was the primary cause of the spill as they found the manhole ajar with wood and concrete debris clogging the infrastructure. Crews manually removed the debris and then used a JetVac truck to successfully clear the line. After assessing the extent of the spill, crews dammed the downstream creek with sandbags, set up a 4-inch pump to pump the untreated wastewater back into the collection system, and flushed the area using a nearby hydrant (dechlorinated water). This approach contained the sewer flow and minimized the environmental impact on the surrounding land and downstream waters. Crews replaced the standard manhole lid and casting with a bolt -down model in order to prevent future tampering and vandalism. In addition, crews completed manhole inspections on the nearby manholes to ensure no additional vandalism of the system had occurred and used a JetVac truck to clean the three upstream and three downstream pipe reaches to ensure the pipes were clear. ®® Gravity Main Cleaning Muldee SSO Area ►N Legend Last Cleaning of Gravity Mains - FY24 All Obff GmWy 1 W m Cey ft�d PrhW • Ma�hoY IfieL' • LFulda� SSO NO N N -' 0 100 Z00 300 400 500 SW 700 800 900 1000 Fee[ Image 1. Spill locotion and identified gravity mains cleaned as part of remediation for incident#202400846 The City's Stormwater Services Division responded and conducted ammonia testing to determine the spill's extent and advise the Department when the site returned to normal conditions. Visual inspection of the affected area and downstream waters confirmed there were no immediately visible adverse environmental impacts or hazards to persons or property, including no fish kill or unnecessary vegetative damage. The Department's cost to remediate this spill was $3,966.52. f� : f � r 17 b s y The incident leading to this spill is exceptional, unintentional, temporary, and caused by factors beyond reasonable control. The staff immediately responded to the incident to mitigate the impact of the spill and used every effort to ensure the infrastructure and environment was restored. The Department replaced the standard infrastructure with bolted down manhole lids to prevent further vandalism of the system at this location. Incident #202401021— May 30, 2024 —1324 Maplewood Drive On May 30, 2024 at 4:23 PM, an overflow was reported near 1324 Maplewood Drive releasing an estimated 270 gallons of wastewater into a tributary of Ellerbe Creek. Crews discovered that grease in the line was the primary cause of the blockage and used a JetVac truck to successfully clear the line. After assessing the extent of the spill, crews dammed the downstream creek with sandbags, set up a 6-inch pump to pump the untreated wastewater back into the collection system, and flushed the area using a nearby hydrant (dechlorinated water). This approach contained the sewer flow and minimized the environmental impact on the surrounding land and downstream waters. Crews used a JetVac truck to clean the three upstream and three downstream pipe reaches to ensure the pipes were clear. In the follow up cleaning, crews found debris as well as grease in the manholes. Due to the proximity of the spill to the City's Dearborn lift station, staff prioritized the cleaning of the gravity main reaches Between the spill location and the lift station. No significant debris were found during follow up with only moderate grease being identified in a few of the lines. 0� W Gravity Main Cleaning Update - Dearborn P.S.

Spill location and identified gravity mains cleaned as port of remediation for Incident#202401021 The City's Stormwater Services Division responded and conducted ammonia testing to determine the spill's extent and advise the Department when the site returned to normal conditions. Visual inspection of the affected area and downstream waters confirmed there were no immediately visible adverse environmental impacts or hazards to persons or property, including no fish !till or unnecessary vegetative damage. The incident was reported to the Department's Industrial Waste staff so they could canvas the neighborhood with information about the effects of non -woven and grease in the collection system. Industrial Waste staff educate the community about the appropriate disposal options, as well as providing interactive giveaways like grease trappers through the website. They distributed 37 mailings regarding the appropriate disposal of nonwovens and grease to educate the community. The Department's cost to remediate this spill was $9,420.73. The incident leading to this spill is exceptional, unintentional, temporary, and caused by factors beyond reasonable control. The staff immediately responded to the incident to mitigate the impact of the spill and used every effort to ensure the infrastructure and environment was restored. The Department has made consistent efforts to prevent such an incident by regular cleaning of the sewer system, a cyclical hot spot program, and constant engagement with the community about proper waste removal. In addition, the Division coordinates with City paving projects to perform pre -paving and post -paving inspections on manholes and gravity mains to ensure that no debris enter the collection system. Ongoing City -Wide Measures to Reduce the Occurrence of SSO Incidents DWM has several programs in place to prevent and reduce the occurrence of 550 incidents. DWM has implemented a Collection System Management, Operations & Maintenance (CMOM) plan that expands and enhances its existing programs. System Flushing and Inspection: DWM routinely contracts cleaning, CCTV inspection, smoke testing, and manhole inspections of portions of the sewer collection system. DWM completes the inspection of the collection system systematically based on City defined geographical basins. In FY23, DWM spent about $22 million on Sewer Rehabilitation projects as a part of its Capital Improvements Programs. DWM ensures the requirements of the collection system permit are met by deploying City crews to clean at least 10% of the collection system annually. DWM measures the cleaning on a fiscal year basis starting July 1. Reporting Period Miles Percent of System FY24 134.97 11.72% FY23 119.86 10.40% FY22 116.16 10.14% Table T. Unique mileage of gravity mains cleaned by DWM Staff for the three most recent fiscal years. Sewer Rehabilitation Program: DWM has an active Sewer Rehabilitation Program. The program includes flow monitoring (25 permanent monitors), CCTV inspection, manhole inspection, easement mowing, field inspections and investigations, point repairs, line replacement, root and grease abatement and cured -in -place manhole and line rehabilitation. There are seven full-time equivalents (FTEs) employees dedicated to DWM's system rehabilitation programs in the Utility Engineering Division of the Department. This workgroup handles flow monitoring and system data management and contract preparation, administration, and inspections. There are 20 FTEs in the City's Collections Line Maintenance (CLM) workgroup in the Sewer Maintenance Division of DWM. This group performs CCTV inspections, hydraulic cleaning activities, manhole inspections, and manhole repairs. They respond to all reported concerns including blockages and overflows. In addition, the CLM crews are supported by the Excavation Services workgroup who perform identified point repairs, line replacements, and cured -in -place lining. The Lift Station Maintenance workgroup (LSM) focuses on oversight and maintenance of the 61 lift stations throughout the service area. This workgroup of 17 FTEs conducts required daily, weekly, monthly, and annual inspections and associated preventive maintenance activities. The 11 FTEs in the Outfall Maintenance (OFM) workgroup perform routine inspection and mowing of easements and inspection of the designated high priority lines. In addition, they facilitate the inspections and repair of the 136 air relief valves (ARVs) in the City's sewer system. Fats, Oils, and Grease Program (FOG): The department's FOG education and outreach effort is conducted by three FTEs. (Staff are shared between the Industrial Pretreatment, Septage and FOG Programs). In addition to working with the Durham County Health Department, staff routinely inspect over 800 food service establishments (FSEs) annually to ensure appropriate cleaning and maintenance of grease interceptors. Staff participate in community events, such as Earth Day, Center Fest and the Bimbe Festival, as well as neighborhood meetings. Department staff deliver residential Fat Trappers to increase awareness of the proper disposal methods for waste. DWM staff also conduct past-SSO follow-up education and enforcement as necessary. DWM invests over $50,000 per year in advertising the proper disposal of FOG on television. Staff post to the City's quarterly newsletter, the Durham Digest, along with multiple mentions in the City Manager's Report known as City Connect, to reach a broad range of Durham residents. Summary: Based upon the documented information provided above regarding this incident, DWM believes that this SSO was exceptional, unintentional, temporary, and caused by factors beyond the City and Department's control. DWM actively manages, operates, and maintains its system in such a manner as to meet or exceed all the requirements of the Collection System permit. As detailed above, DWM systematically inspects, flushes, and rehabilitates its wastewater collection system. The Department also actively works to regulate and educate the community regarding what should and should not be discharged into the City's sewer collection system. The department staff welcomes the opportunity to meet with you and your staff to review our program and discuss constructive ways to improve what we are already doing in the City of Durham.

After crew arrived onsite they tried to stop overflow with mini flusher but were unsuccessful. They used 'et/vac combo to flush line with vacuum tube in manhole. After knocking the pressure of the flow down they were able to see the sticks an( concrete blocking the invert headed downstream. They removed the debris that had been tossed in the manhole remediating all issues. Crews cleaned up around manhole removing all sail that was touched by wastewater and uttin back seed and straw in the area. We set up a pump downstream with sandbags blocking the flow. We used the pump to remove all untreated wastewater from Ellerbe Creek and pump it back into manhole 21666 where we tested for zero ammonia levels. Crew will continue to monitor area until bolt down manhole is complete. Local storm water quality was called to inform them as well of the overflow to test creek levels for pump removal.
