This fetter is in response to the notice dated January 24, 2022 which was received by the City of Durham on
February 3, 2022. The January 24, 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 (SSOs) which occurred in the City's sewer collection system
between December 1, 2021 and December 31, 2021.
As requested, the City of Durham, Department of Water Management (DWM) is providing information about the
two 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 site visits, inspections, and easement maintenance.
Incident # 202102248 -1610 Juniper Street— December 9, 2021
On December 9, 2021, an overflow occurred near 1610 Juniper Street with an estimated 300 gallons of wastewater
discharging into Goose Creek. This overflow occurred due to a blockage in the sewer main caused by a collection of
grease. The line was initially cleared by a quick response truck. Crews set up a JetVac truck and cleaned all grease
and debris out of the manhole. The creek was dammed downstream with sandbags, the area was flushed using a
nearby hydrant (dechlorinated water) and a 4-inch pump was set up to pump the untreated wastewater back into
the collection system. After the initial cleanup was completed, crews used a JetVac truck to clean the three
upstream manholes and three downstream manholes to ensure the pipes were clear per the division's Standard
Operating Protocols.
The department's Industrial Waste Control/FOG program staff distributed notices to the neighborhood to inform
and educate the residents on the effects of grease in the collection system and the appropriate disposal options.
At this time, the indicated series of reaches are on a Hot Spot program for the immediate future and will be
checked by CCTV truck every two weeks until further notice.
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.

Page 2 of 3
City of Durham crews have followed up by cleaning the lines above and below the incident location and using CCTV
trucks to ensure the pipes are cleared. As required, a news release was issued within the 24-hour window. The cost
to remediate this spill was $9,783.15.
Incident # 202102307 —1221 Kendall Drive — December 27, 2021
On December 27, 2021, an overflow occurred near 1221 Kendall Drive releasing an estimated 960 gallons of
wastewater into Little Lick Creek. This blockage was caused by a buildup of unknown debris in the line. The line
was initially cleared by a quick response truck. Crews setup a JetVac truck and cleaned the debris out of the
manhole. The creek was dammed downstream with sandbags, the area was flushed using a nearby hydrant
(dechlorinated water) and a 4-inch pump was set up to pump the untreated wastewater back into the collection
system. Crews also installed a locking lid on MH 12163 to prevent vandalism. After the initial cleanup was
completed, crews used a JetVac truck to clean the three upstream manholes and three downstream manholes to
ensure the pipes were cleared per the division's Standard Operation Protocols.
The department's Industrial Waste Control/FOG staff have developed public communications, including ads on
local television stations, regarding the impact of woven and non -woven materials on the sewer system. These
communications also educate residents on the appropriate disposal of these materials via trash to prevent backups
and spills.
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 were observed.
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
$8,970.56
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.
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. As of December 31, 2021, the City
has cleaned 7.76% of the system.
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 20 employee positions in
our Collections Systems Maintenance workgroup in the Water and Sewer Maintenance (WSM) Division of
DWM. This group performs CCTV inspections, hydraulic cleaning activities, mowing, and manhole inspection

Page 3 of 3
and repair. Crews respond to blockages and overflows. The department does contract inspections as well. In
addition, crews from the main line workgroup of WSM perform point repairs, line replacements, and 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 18-
member workgroup 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 several
community events (Earth Day, Center Fest, 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 these
SSOs were exceptional, unintentional, temporary and caused by factors beyond the City's/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.
Department of Water Management 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.Greeley durhamnc.Fov.

Donald F. Greeley, Director, PE,

News Release
For Immediate Release: December 10, 2021
City of Durham contains sewer spill near 1610 Juniper Street
DURHAM, N.C. —The City of Durham Department of Water Management reports that on December 9, 2021
staff responded to a manhole overflowing near 1610 Juniper Street. Approximately 300 gallons of
untreated wastewater flowed into an unnamed tributary of Goose Creek. The overflow was caused by
blockage of grease in the sewer line.
Staff were notified of the overflow at 1:30 p.m. on December 9, and the overflow was stopped at 2:30 p.m.
Crews dammed the creek downstream, pumped the untreated wastewater back into the sewer system,
and flushed the sewer line around the manhole to remove any remaining buildup of grease in the line.
As a reminder, only water, human waste, and toilet paper are permitted to be discharged into the sewer
system. All other materials —including fats, oils, and grease (FOG) that should not be allowed into the
sink —contribute to sanitary sewer overflows. To learn more about the way FOG clogs 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 9, 2021, as required by state regulations/law. For more information, contact Junior Mobley,
Superintendent of Water & Sewer Maintenance.

How was the SSO remediated (i.e. Stopped and cleaned up)?
Crews used a quick response mini flusher to removed blockage from asset id 12163. After flushing crews removed
blockage and found the issue was 25ft of twisted sisal rope entangled with non woven materials. After removal crews test
several areas of the creek to find ammonia levels at 0 in order to set up pump to bypass all untreated wastewater back in1
the Sewer System. After testing creek crews set up a bypass pump at 3622 Wake Forest Hwy and used Manhole 17833
to discharge all the untreated wastewater. Crews set up diffusers at two severate hydrants on Horseshoe Rd. to help pu:
untreated wastewater to pump. Pump location used sandbags to dam creek so no wastewater_ could get by. Crews calle
Dwr State at 3:15am on12/28/21 and spoke with George Jones and reported spill. After setup crews used trashcans to
remove all debris and a percentage of dirt on ground to make sure no untreated waste water or debris was left on ground
We removed 5 industrial size trash bins from site filled with dirt and tainted grass. After complete removal crews used
straw and grass seed to fix area to put it back at its natural state. Crews will clean 7 total assets in area to ensure no
debris left in sewer main. We will do 3 assets above and 3 assets below. Also these lines will be put on Collections
department hots of program. We monitor these lines monthly to ensure no follow up SSO in area. On 12/29/21 Storm
Water Quality was called at 6am so they can check all Dolnts on contact in creek with ammonia.
As a representative for the responsible party, I certify that the information contained in this report is true and accurate to the

News Release
For Immediate Release: December M, 2021
City of Durham contains sewer spill near 1210 Kendall Drive
DURHAM, N.C. -- The City of Durham Department of Water Management reports that on December 27,
2021 staff responded to a manhole overflowing near 1210 Kendall Drive. Approximately 960 gallons of
untreated wastewater flowed into little Lick Creek Watershed. The overflow was caused by debris in the
sewer line.
Staff were notified of the overflow at 7:23 p.m. on December 27, and the blockage was cleared at 10:35
p.m. Crews flushed and removed the blockage, dammed the creek, and pumped the untreated wastewater
back into the sewer system.
As a reminder, only water, human waste, and toilet paper are permitted to be discharged into the sewer
system. All other materials —including fats, oils, and grease (FOG) that should not be allowed into the
sink —contribute to sanitary sewer overflows. To learn more about the way FOG clogs 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 28, 2021, as required by state regulations/law. For more information, contact Junior Mobley,
Superintendent of Water & Sewer Maintenance.
