The June 14, 2021 letter states that the City of Durham is provided an opportunity to present evidence and justification to demonstrate that the proposed civil penalties for the Notice of Violation (NOV) should not be assessed for the sanitary sewer overflows (SSOs) which occurred in the City's sewer collection system between May 1, 2021 and May 31, 2021. As requested, the City of Durham, Department of Water Management (DWM) is providing information about the three incidents which occurred during this timeframe which will support the City's position that despite meeting all the conditions of the City's Collection System permit including site visits, inspections And easement maintenance, these events were exceptional, unintentional, temporary and beyond the City's exercise of reasonable control. Incident # 202101269 — 900 Sprina Meadow Drive — Mav 1 2021 On May 1, 2021, manhole #31508 at 900 Spring Meadow Drive overflowed with an estimated 695 gallons of wastewater discharging into Third Fork Creek. This overflow occurred due to a blockage in the sewer main caused by roots. Water and Sewer Maintenance staff used a high- pressure jet and a root cutter to remove the blockage from the main, cleaning the lines with a VAC -ALL combo truck. The creek was dammed and then flushed using dechlorinated water from a nearby hydrant, pumping the untreated wastewater back into the sanitary sewer system (4" pump used). The City's Stormwater Services Division responded and conducted ammonia testing to help determine the extent of the spill and to advise when the site returned to normal conditions. No immediately visible adverse environmental impacts or hazards to persons or property occurred. Staff will continue to monitor this portion of the collection system for root intrusion and if the roots become an ongoing issue, the area will be included in the City's root control contract. Page 2 of 4 City of Durham crews have followed up by cleaning the lines above and below the incident location and using CCTV trucks. As required, a news release was issued within the 24-hour window. The cost to remediate this spill was $11,359.69. Incident # 202101305 - 2001 Duke University Road — May 11, 2021 On May 11, 2021, manhole #13697 at 2001 Duke University Road overflowed with an estimated 900 gallons of wastewater discharging into Sandy Creek. This overflow occurred due to a blockage in the sewer main caused by roots. Water and Sewer Maintenance staff used a high- pressure jet and a root cutter to remove the blockage from the main, cleaning the lines with a VAC -ALL combo truck. The creek was dammed and then flushed using dechlorinated water from a nearby hydrant, pumping the untreated wastewater back into the sanitary sewer system (4" pump used). The City's Stormwater Services Division responded and conducted ammonia testing to help determine the extent of the spill and to advise when the site returned to normal conditions. No immediately visible adverse environmental impacts or hazards to persons or property occurred. Staff will continue to monitor this portion of the collection system for root intrusion and if the roots become an ongoing issue, the area will be included in the City's root control contract. City of Durham crews have followed up by cleaning the lines above and below the incident location and using CCTV trucks. As required, a news release was issued within the 24-hour window. The cost to remediate this spill was $5,333.71. Incident # 202101343 — 3101 Fayetteville Street — May 19 2021 On May 19, 2021, a contractor for the City and City Utility Engineering staff walking the outfall discovered that a large tree had fallen due to severely eroded creek bank behind 3101 Fayetteville Street. When the tree fell, it significantly damaged the sewer main, allowing an estimated 11,325 gallons of wastewater to be discharged into Third Fork Creek. As a part of the routine High Priority Inspection program, the site was visited on May, 4 2021; inspectors did not note any immediate concerns about bank stability at the time of the inspection. Water and Sewer Maintenance staff brought in an excavation crews to dig out the area and the section of damaged pipe was replaced with 20 feet of new 12-inch Ductile iron pipe. The creek was dammed and then flushed using dechlorinated water from a nearby hydrant, pumping the untreated wastewater back into the sanitary sewer system (4" pump used). The City's Stormwater Services Division responded and conducted ammonia testing to help determine the extent of the spill and to advise when the site returned to normal conditions. No immediately visible adverse environmental impacts or hazards to persons or property occurred. City of Durham crews have followed up by cleaning the lines above and below the incident location and using CCTV trucks. As required, a news release was issued within the 24-hour window. The cost to remediate this spill was $22,356.91. Ongoing City -Wide Measures to Reduce the Occurrence of SSOs The City has several programs in place to reduce and/or prevent the occurrence of SSOs. The City has implemented a CMOM plan that expands and enhances its existing programs. Page 3 of 4 ■ System Flushing and Inspection: The City routinely contracts flushing, CCTV inspection, smoke testing and manhole inspections of portions of the sewer collection system. The City is completing the inspection of the collection system systematically through City defined basins. Additionally, the City ensures the requirements of the collection system permit are met by deploying City crews to flush at least 10% of the collection system annually with a goal of exceeding the requirement by at least 2 to 5% each year. The City measures the flushing on a fiscal year basis. For the FY 2021 year to date, the City has cleaned 12.88% of the system. As operations normalize post-Covid-19, staff will dedicate more time to this program. ■ Sewer Rehabilitation Program: The City 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 4 employee positions dedicated to the City's system rehabilitation programs in the Utility Engineering Division of DWM. This workgroup handles flow monitoring and system data management and contract preparation, administration and inspections. There are 21 employee positions in our Collections Systems Maintenance workgroup in the Water & Sewer Maintenance (WSM) Division of DWM. This group performs CCTV inspections, hydraulic cleaning activities, mowing and manhole inspection and repair. They respond to blockages and overflows. WSM does contract inspections as well. In addition, crews from the Main Line workgroup of WSM perform point repairs, line replacements and some cured -in -place lining. The department established the Lift Station Maintenance Division in 2018 to focus oversight and maintenance of the 65 lift stations throughout the service area and the 136 ARVs in the system. This 14-member work group conducts the required daily/weekly inspections and associated preventive maintenance activities. The City spends more than $5,000,000 on Sewer Rehabilitation projects annually as a part of its Capital Improvements Programs. ■ Fat Oils and Grease Program (FOG): The department's FOG education and outreach effort is conducted by 3.0 FTEs (staff shared 50/50 with the Industrial Waste Control Program). In addition to working closely 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 participates in a number of community events (Earth Day, CenterFest, and Landlord Workshops) as well as neighborhood meetings to increase awareness of what is appropriate to put in the sewer system. FOG staff conducts post-SSOs follow-up education and enforcement as necessary. The City also invests more than $35,000 per year in advertising (TV commercials, social media, etc.) regarding the proper disposal of FOG. Summary Based upon the documented information provided above regarding these incidents, the City believes that overflows were exceptional, unintentional, temporary and caused by factors beyond the City's/department's reasonable control. The City actively manages, operates and Page 4 of 4 maintains its system in such a manner as to meet all the requirements of the Collection System permit. As detailed above, the City systematically inspects, flushes and rehabilitates its wastewater collection system. The department works actively to educate the community regarding what should and should not be discharged into the City's sewer collection system. 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.

A contractor for DWM's Utilities Engineering Division discovered that a tree had fallen, damaging and dislodging a section of the 12" sewer main. This inforeseen incident caused approximately 11,325 gallons of untreated wastewater to flow into Third Fork Creek. The dill was contained within that section of the creek. Due to a prior overflow along the creek on May 16, equipment — sandbags and pumps --were already in place, and DWM personnel were monitoring the area as follow up to the May 16 spill. Staff were notified of the spill at 11:55 a.m. and the sewer main was repaired at 7:28 p.m. Crews jetted the sewer main, repaired the pipe, remediated the spill site, flushed the creek, and pumped the untreated wastewater back into the sanitary sewer system. DWM crews will return to the site and repair the washed out stream bank and remediate the area. The N.C. Department of Environmental Quality Division of Water Resources was notified of the event on May 19, 2021, as required by state regulations/law.
