Dear Mr. Vinson,
Please permit this letter to respond to the above referenced Notice of Violation & Intent to
Issue Civil Penalty received on January 22, 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 550s that occurred in
the City's wastewater collection system between December 1, 2023, and December 31, 2023.
Incident #202301622 — December 9, 2023 —1508 Pinecrest Road
On December 9, 2023 at 10:32 AM, an overflow was reported near 1508 Pinecrest Road
releasing an estimated 458,000 gallons of wastewater into a tributary of Sandy Creek. Crews
discovered that a tree fell during a wind event with gusts reported over 26 mph. A tree located
outside of the easement fell and damaged an aerial gravity main causing the release of
wastewater. Crews set two 4-inch by-pass pumps to divert flow and brought in a contractor to
it v

make an emergency 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 two nearby hydrants (dechlorinated
water). This approach contained the sewer flow and minimized the environmental impact on
the surrounding land and downstream waters. No grease or non -woven debris were observed.
The contractors set a larger bypass pump and later returned to replace 60 feet of the gravity
main.
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 aerial high priority lines (HPLs) from
incidents such as this one. Staff perform comprehensive bi-annual inspections of all sewer lines
categorized as a HPL including looking for obstructions, changes in the creek bank and bed, and
trees in proximity to the easement. If possible, City staff will remove trees or shrubs that cause
an immediate threat to infrastructure. The Department also contracts to remove trees that
pose a risk to the infrastructure. To date, the Department has spent $1,192,643.80 on the
current tree removal contract that was started in February 2023.
The Department's initial cost to respond to this spill was $22,375.99 with an additional
$3,477.71 spent to make the emergency repair. The contractor repair costs totaled to
$57,785.63. Together, the Department's costs to remediate this spill was approximately
$98,639.33.

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 inspections and removal of trees near exposed infrastructure. The 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.

Incident #202301655 — December 15, 2023-4800 Marlborough Way
On December 15, 2023 at 4:08 PM, an overflow occurred near 4800 Marlborough Way
releasing an estimated 810 gallons of wastewater into an unnamed tributary of Third Fork
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 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.
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 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.
The Department's cost to remediate this spill was $3,410.36.
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 removal. 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 #202301729 — December 26, 2023 —1021 Wedgewood Lane
On December 26, 2023 at 11:34 AM, an overflow was reported near 1021 Wedgewood Lane
releasing an estimated 14,400 gallons of wastewater into a tributary of Northeast Creek. Crews
discovered that non -woven debris and fat solids were the cause of the backup. Staff 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 and a 2-inch pump to transfer 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 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 immediate visible adverse environmental impacts or hazards to persons or property,
including no fish kill 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.
The Department's initial cost to respond to this spill was $ 6,812.7.
The factors leading to this spill are unintentional, temporary, and the Department has made
consistent strategic efforts to prevent such an occurrence. 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.
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 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.

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 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 post-550 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 S5O 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 Don.GreelevPdurhamnc.eov.
Sincerely,
Donald F. Greeley,
Director

DURHAM, N.C. —The City of Durham Department of Water Management reports that on

Approximately 14,400 gallons of untreated wastewater flowed into Northeast Creek North
Prong Tributary. The cause of the overflow was nonwoven material clogging the sewer line.
Staff were notified of the overflow at 11:34 a.m. on December 26, 2023, and the spill was
stopped at 1:10 p.m. The crew cleared the blockage, dammed the creek downstream and
pumped the untreated wastewater back into the sewer system. There were no observed
hazards to persons, property, or the environment.
As a reminder, only water, human waste, and toilet paper are permitted to be discharged into
the sewer system. All other materials —nonwoven materials (so called flushable wipes and
rags) and fats, oils, and greases (FOGS) that should not be allowed into the sink or toilet —
contribute to sanitary sewer overflows. To learn more about the way FOGS and nonwovens
clog pipes and how to properly dispose of them, visit our Industrial Waste Control,
Pretreatment, and Grease Reduction Program at www.durhamnc.gov/1077.
The N.C. Department of Environmental Quality Division of Water Resources was notified of
the event on December 26, 2023 as required by state regulations/law. For more information,
contact Junior Mobley, Superintendent of Water & Sewer Maintenance.

SUBJECT: NOTICE OF VIOLATION & INTENT TO ISSUE CIVIL PENALTY
Tracking No.: NOV-2024-DV-0010
Sanitary Sewer Overflows - December 2023
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 Report/s 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:

27713
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.
If you have any questions, please do not hesitate to contact Kevin Fowler with the Water Quality Section in the
Raleigh Regional Office at 919-791-4200 or via email at [e-mail].
