Dear Mr. Vinson,
Please permit this letter to respond to the above referenced Notice of Violation & Intent to
Issue Civil Penalty received on March 26, 2024. 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 the 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 February 1, 2024 and February 29, 2024.
Incident#202400407 — February 1, 2024-905 Parkridge Road
On February 1, 2024 at 5:08 PM, an overflow occurred near 905 Parkridge Road releasing an
estimated 12,100 gallons of wastewater into a storm water ditch in the Third Fork Creek basin.
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 determined that no
waste water entered the waters of the State or any unnamed tributary of the Third Fork Creek.

Crews carefully dammed the storm water ditch with sandbags, used a JetVac truck to vacuum
the untreated wastewater, and flushed the area using a nearby hydrant (dechlorinated water).
This approach contained the sewer 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.
The incident was reported to the Department's Industrial Waste staff so they could canvas the
neighborhood and nearby homeowner's associations with information about the effects of non-
woven materials 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.
During the follow up investigation, crews cctv'd the three upstream and three downstream pipe
reaches and found areas containing root growth. These gravity mains have been added to the
annual lining contract that the Department is funding and the manholes have been sent to the
Department's excavation workgroup for sealing.
The Department's cost to remediate this spill was $3,319.71.
The incident leading to this spill is exceptional, unintentional, temporary, and caused by factors
beyond reasonable control. 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 disposal. 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.
Incident#202400418 — February 5, 2024 — 2006 Aiken Avenue
On February 5, 2024 at approximately 11:00 AM, an overflow was reported near 2006 Aiken
Avenue releasing an estimated 4,200 gallons of wastewater into a tributary of Ellerbe Creek.
Crews responded and promptly discovered that separation of the pipe was the cause of the
spill. Crews used a by-pass pump to divert flow and called in an excavation crew to make the
repair. 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 used a JetVac truck to clean the three upstream and three
downstream pipe reaches to ensure the pipes were clear.
The pipe separation occurred in a pipe segment that was scheduled to be replaced as part of
our Aiken Avenue Sewer Rehabilitation Project. The contractor had recently started
construction on the project.
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.
DWM takes substantial and consistent actions to protect and monitor high priority lines (HPLs).
Staff perform comprehensive bi-annual inspections of all sewer lines categorized as an HPL
including looking for obstructions, changes in the creek bank and bed, and trees in proximity to
the easement. This section of easement had been identified as a high -risk area previously and
the location was put on a replacement contract. Following this spill, the Department escalated
the replacement of the pipe at 2006 Aiken Avenue to fully remediate the site.
The Department's initial cost to respond to this spill was $17,141.94. The contractor project
costs totaled to $680,772.72. Together, the Department's costs to remediate this spill was
approximately $697,914.66

Table 1. Responsive costs accrued by the Department to remediate 2006 Aiken Avenue and area.
The incident leading to this spill is exceptional, unintentional, temporary, and caused by factors
beyond reasonable control. The Department has made consistent efforts to prevent such an
incident by regular HPL inspections and a proactive pipe replacement plan. Department staff
immediately responded to the incident to mitigate the impact of the spill and used
extraordinary efforts to ensure the infrastructure and environment were restored.
Ongoing City -Wide Measures to Reduce the Occurrence of SSO Incidents
DWM has several programs in place to prevent and reduce the occurrence of SSO 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 approximately $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.

Table 2. 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 Systems Maintenance (CSM) 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 CSM 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 63
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 post-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. If you have any questions or need any additional information, please do not hesitate
to contact me at [phone] or via email at [e-mail].
Sincerely,
Donald F. Greeley,

Sanitary Sewer Overflows - February 2024
Collection System Permit No. WQCS00005
Durham Collection System
Durham County
Dear Mr. Greeley:
A review has been conducted of the self -reported Sanitary Sewer Overflows (SSO's) 5-Day Reports submitted by
City of Durham. The Division's Raleigh Regional Office concludes that the City of Durham violated Permit Condition
I (2) of Permit No. WQCS00005 by failing to effectively manage, maintain, and operate their collection system so
that there is no SSO (Sanitary Sewer Overflow) to the land or surface waters and the SSO constituted making an
outlet to waters of the State for purposes of G.S. 143-215.1(a)(1), for which a permit is required by G.S.
143-215.1.
The Raleigh Regional Office is providing the City of Durham an opportunity to provide evidence and justification as
to why the City of Durham should not be assessed a civil penalty for the violation(s) that are summarized below:

DocuSign Envelope ID: OCAF9C57-120A-4E53-98F4-2244CE231432
This Notice of Violation / Notice of Intent to Enforce (NOV/NOI) is being issued for the noted violation. Pursuant
to G.S. 143-215.6A, a civil penalty of not more than twenty-five thousand dollars ($25,000.00) may be assessed
against any person who violates or fails to act in accordance with the terms, conditions, or requirements of any
permit issued pursuant to G.S. 143-215.1.
This office requests that you respond to this Notice, in writing, within 10 business days of its
receipt. In your response, you should address the causes of non-compliance, remedial actions, and all other
actions taken to prevent the recurrence of similar situations. The response to this correspondence will be
considered in this process. Enforcement decisions will also be based on volume spilled, volume reaching surface
waters, duration and gravity, impacts to public health, fish kills or recreational area closures. Other factors
considered in determining the amount of the civil penalty are the violator's history of non-compliance, the cost of
rectifying the damage, whether the spill was intentional and whether money was saved by non-compliance.
