The above referenced April 18, 2022 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 (SSO) which occurred in the City's sewer collection system
between March 1, 2022 and March 31, 2022.
As requested, the City of Durham, Department of Water Management (DWM) is providing information about the
four incidents that occurred during this timeframe to support the City's position that these events were
exceptional, unintentional, temporary, and beyond the City's exercise of reasonable control despite meeting all the
conditions of the City's Collection System permit including system cleaning, site visits, inspections, and easement
maintenance.
Incident # 202200321-110 Nancy Rhodes Drive — March 6. 2022
On March 6, 2022, an overflow occurred near 110 Nancy Rhodes Drive releasing an estimated 27,900 gallons of
wastewater into an unnamed tributary of the Eno River. The quick response team cleared the line by breaking up
the initial blockage which was caused by debris. Water and Sewer Maintenance (WSM) crews assessed the creek
to determine the extent of the spill and then 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). Crews used a JetVac truck to clean the three upstream and three downstream pipe reaches
to ensure the pipes were cleared of any remaining debris. The type of debris removed from the line indicates that
the blockage was due to vandalism. To prevent similar issues of this nature going forward, crews installed bolt -
down manhole covers on four manholes in the area to prevent unauthorized access.
The City's Stormwater Services Division responded and conducted ammonia testing to help determine the spill's
extent and advise when the site returned to normal conditions. No immediately visible adverse environmental
impacts or hazards to persons or property were observed.
WSM crews have followed up by cleaning three upstream and three downstream pipe reaches at the incident
location and used CCTV trucks to ensure the pipes remain clear. As required, a news release was issued within the
24-hour window. The cost to remediate this spill was $16,110.24.

Incident # 202200342 —1031 Bacon Street — March 8, 2022
On March 8, 2022, an overflow occurred near 1031 Bacon Street releasing an estimated 1,120 gallons of
wastewater into an unnamed tributary of Third Fork Creek. Initial attempts to clear the blockage by the quick
response crew were unsuccessful so a JetVac truck was quickly deployed. Crews discovered that roots were the
cause of the blockage and used a mechanical cutting tool to cut the root ball and 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). Crews then used a JetVac truck to clean the three upstream and three downstream pipe
reaches to ensure the pipes were clear.
The City's Stormwater Services Division responded and conducted ammonia testing to help determine the spill's
extent and advise when the site returned to normal conditions. No immediately visible adverse environmental
impacts or hazards to persons or property were observed.
Staff will continue to monitor this reach of the collection system for root intrusion on a periodic basis. If the roots
are observed to be an ongoing issue, the area will be added to the City's chemical root control contract or
escalated to the slip -lining contract dependent on the severity of observed growth.
WSM crews have followed up by cleaning three upstream and three downstream pipe reaches at the incident
location and using CCTV trucks to ensure the pipes remain clear. As required, a news release was issued within the
24-hour window. The cost to remediate this spill was $9,746.77.
Incident# 202200377 —1109 Oakland Avenue — March 12 2022
On March 12, 2022, contractors replacing a Duke Power utility pole damaged an 8-inch gravity main near 1109
Oakland Avenue resulting in an estimated discharge of 1,500 gallons of wastewater into an unnamed tributary of
Ellerbe Creek. Crews immediately deployed a bypass pump to stop the discharge; the bypass remained in place
while the repairs were made. After determining 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).
Since the utility pole needed to be supported by Duke Power crews while the repair was completed, WSM
Excavation Crews scheduled the repair of the damaged pipe during normal operational hours. The bypass pump
remained in place until the sewer pipe repair was completed. Crews used a JetVac truck to clean the three
upstream and three downstream pipe reaches to ensure the pipes were clear.
The City's Stormwater Services Division responded and conducted ammonia testing to help determine the spill's
extent and advise when the site returned to normal conditions. No immediately visible adverse environmental
impacts or hazards to persons or property were observed.
WSM crews have followed up by cleaning the lines upstream and downstream of the incident location and using
CCTV trucks to ensure the pipes have remained clear. There is no further indication of damage from the utility
construction. As required, a news release was issued within the 24-hour window. The cost to remediate this spill
was $15,509.51.

Incident#i 20220043_4 —1901 Jersey Avenue — March 20, 2022
On March 20, 2022, an overflow occurred near 1901 Jersey Avenue releasing 680 gallons of wastewater into an
unnamed tributary of Sandy Creek. Crews used a quick response truck to clear the blockage which was caused by
debris including rope and a metal rod in the manhole. 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). Crews then used a JetVac
truck to clean the three upstream and three downstream pipe reaches to ensure the pipes were clear of any
remaining debris. Additionally, since the blockage occurred due to vandalism, crews installed a bolt -down manhole
cover to prevent further unauthorized access.
The City's Stormwater Services Division responded and conducted ammonia testing to help determine the spill's
extent and advise when the site returned to normal conditions. No immediately visible adverse environmental
impacts or hazards to persons or property were observed.
WSM crews have followed up by cleaning the lines upstream and downstream of the incident location and using
CCTV trucks to ensure the pipes remain clear. As required, a news release was issued within the 24-hour window.
The cost to remediate this spill was $10,626.20.
Ongoing City -Wide Measures to Reduce the Occurrence of SSOs
The City has several programs in place to prevent and reduce the occurrence of SSOs. The City has implemented a
CMOM plan that expands and enhances its existing programs.
■ System Flushing and Inspection: The City routinely contracts cleaning, CCTV inspection, smoke testing, and
manhole inspections of portions of the sewer collection system. The City completes the inspection of the
collection system systematically based City defined geographical basins.
The City ensures the requirements of the collection system permit are met by deploying City crews to clean 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 cleaning on a fiscal year basis starting July 1. As of March 31, 2022, 11.17% of the
City's collection system has been cleaned by City staff and contractors.
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 four full-time equivalents (1=TEs) employees 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
20 FTEs in the City's Collections Systems Maintenance workgroup in the Water and Sewer Maintenance (WSM)
Division of DWM. This group performs CCTV inspections, hydraulic cleaning activities, mowing, manhole
inspections, and manhole repairs. They respond to all reported concerns including blockages and overflows. In
addition, the CSM crews are supported by the Excavation Services workgroup of WSM who perform identified
point repairs, line replacements, and cured -in -place lining. In 2018, the department established the Lift Station
Maintenance Division to focus on oversight and maintenance of the 65 lift stations throughout the service area
and the 136 ARVs in the system. This 18 FTE workgroup conducts required daily and 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.

Page 4 of 4
Fats, Oils, and Grease Program (FOG): The department's FOG education and outreach effort are conducted by
three 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 several
community events, such as Earth Day, Center Fest, and Landlord Workshops, as well as neighborhood
meetings to increase awareness of the proper disposal of waste and the impact on the wastewater system.
FOG staff conducts post-SSO follow-up education and enforcement as necessary. The City also invests more
than $35,000 per year in advertising the proper disposal of FOG on television, social media, and other media
avenues.
Summary:
Based upon the documented information provided above regarding these incidents, the City believes that these
SSOs were exceptional, unintentional, temporary, and caused by factors beyond the City and Department's
reasonable control. The City 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, the City systematically inspects,
flushes, and rehabilitates its wastewater collection system. The Department actively works to 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. If you have any questions
or need any additional information please do not hesitate to contact me at [phone] or via email at
