Dear Mr. Vinson,
NC Dept of Environmental Quality
DEC 15 202Z
Raleigh Regional Office
The above referenced 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 June
1, 2022 and June 30, 2022.
For the purposes of supporting the City's position that these events were exceptional, unintentional, temporary,
and beyond its reasonable control, the Durham Department of Water Management (DWM) is providing
information about the requested incidents that occurred during this timeframe. All conditions of the City's
Collection System permit are met by the Department, including system cleaning, site visits, inspections, and
easement maintenance.
Incident# 202200863 - 314 Rondela Drive - June 7 2022 9:20 PM
On June 7, 2022 at 9:20 PM, an overflow occurred near 314 Rondelay Drive releasing an estimated 1,750 gallons of
wastewater into a retention pond in the Lick Creek basin. Crews discovered that damage to a force main coupling
at the lift station was the cause of the overflow and used a bypass pump to stop the flow while infrastructure
repairs were made to the wet well. After assessing the extent of the spill, crews cleaned the affected area using a
Vac truck.
Department staff conducted ammonia testing to help determine the spill's extent at three distinct locations
around the retention pond. No visible adverse environmental impacts or hazards to persons or property were
observed. Crews perform weekly inspections of the lift station and have observed no lasting effects to persons,
property, or the environment. As of July 19, 2022, the impacted lift station was moved out of service and all flow
was routed to the new Southeast Regional Lift Station (SERL).
A news release was issued within the 24-hour window. The cost to remediate this spill was $4,821.98.

Incident# 202200939 - 27 Jenee Lane - June 19 2022 4:11 PM
On June 19, 2022 at 4:11 PM, an overflow occurred near 27 Jenee Lane releasing an estimated 83,600 gallons of
wastewater into a tributary of Little Lick Creek. Crews discovered that debris in the line was the 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 4-inch pump to pump the untreated wastewater back into
the collection system, and flushed the area using nearby hydrants (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.
The department's Industrial Waste Control staff responded to this event with an approximate 360 mailings and
200 non -woven door hanger packets. Staff also provided approximately 400 information cards for two nearby
apartment complexes to distribute to future tenants.
In addition to the news release issued within the 24-hour window, the Department published a Notice of Discharge
as required in the locally circulating news publications. The cost to remediate this spill was $11,079.14.
Incident# 202200973 -1833 Camden Avenue - June 21, 202212:41 PM
On June 21, 2022 at approximately 12:41 PM, an overflow occurred near 1833 Camden Avenue releasing an
estimated 2,850,000 gallons of wastewater into a tributary of Ellerbe Creek. Staff discovered a large tree fell and
damaged a 30-inch gravity aerial sewer line during a storm. Immediately, upon discovery, crews set up a bypass
pump to isolate the damaged portion of the sewer line while the infrastructure was repaired. 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 4 nearby hydrants
(dechlorinated water). DWM staff replaced a large section of damaged line and performed clean-up activities to
minimize the impact to the environment. The aerial line and HPL was visually inspected in October 2022 as part of
the biannual HPL inspection project and no long term impacts were noted on the infrastructure or the
environment.
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.
In addition to the news release issued within the 24-hour window, the Department published a Notice of Discharge
as required in the locally circulating news publications. The cost to remediate this spill was $76,597.65.

Oneoing Citv-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 E
Collection System Management, Operations & Maintenance (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 on 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 2% to 5% each year.
The City measures the cleaning on a fiscal year basis starting July 1. As of June 30, 2022, 10.10% of the City's
collection system had 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 (FTEs) 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
21 FTEs in the City's Collections Systems Maintenance (CSM) 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 (LSM) to focus on oversight and maintenance of the 63 lift
stations throughout the service area and the 136 air relief valves (ARVs) in the system. This workgroup of 21
FTEs conducts required daily, weekly, monthly, and annual 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.
Fats Oils, and Grease Program (FOG): The department's FOG education and outreach effort is conducted by
three FTEs (staff 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 several community events, such as Earth Day, Center Fest and Bimbe, as well as neighborhood
meetings. Department staff deliver residential Fat Trappers to increase awareness of the proper disposal
methods for waste. FOG staff also conducts post-SSO follow-up education and enforcement as necessary. The
City 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 these incidents, the City believes that these
SSOs were exceptional, unintentional, temporary, and caused by factors beyond the City and Department's
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 also 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

Donald F. Greeley
