City of Durham Collection System, Durham County
Dear Mr. Vinson,
This letter is in response to your notice dated September 14,2020 which was received by the City of Durham on
September 24,2020. The September 14`h letterstates that the City of Durham is provided an opportunityto
presentevidence and justification to demonstrate thatthe proposed civil penalties forthe Notice of Violation
(NOV) should not be assessed forthe sanitary sewer overflows (SSOs) which occurred in the City's sewe rcollection
system between August 1, 2020 and August 31, 2020.
As requested, the City of Durham, Department of Water Management (DWM) is providing information about three
incidents which occurred duringthis timeframe which will support the City's position that despite meeting all the
conditions of the City's Collection System permit including site visits, inspections and easement maintenance,
these events were exceptional, unintentional, temporaryand beyond the City's exercise of reasonable control.
DWM staff consider it especially important to note that the attached map shows that the SSOs are dispersed
throughout Durham's service area.
Incident# 202002325 —135 Latta Road — August 12, 2020
On August 11`h a manhole (#25841) at 135 Latta Road overflowed, with an estimated 820 gallons of untreated
wastewater discharging into an unnamed tributaryof Crooked Creek. The overflow occurred due to a blockage in
the sewermain caused by grease from businesses and homes in the area. Water and Sewer Maintenance staff
used a high-pressure jetand vacuum to remove the blockage from the manhole, cleaningthe lines above and
below with a jettruck. The creek was flushed using nearby hydrant(dechlorinated) and the untreated
wastewaterwas pumped back into the collection system.
The City's StormwaterServices Division responded and conducted ammonia testingto 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 occurred.
The department's FOG program staff distributed notices in the neighborhood regarding the effects of grease on
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, being checked by CCTV truck everytwo weeks until further notice.
As required, a news release was issued within the 24-Dour window. The cost to remediate this spill was $3,843.33.

Incident# 202002499 —Stadium Drive/Woodereen Drive -- August27, 2020
On August 271h a manhole (#23419) at Stadium Drive and Woodgreen Drive overflowed, with an estimated 645
gallons of untreated wastewater discharging into an unnamed tributary ofIumping Run Creek. The overflow
occurred due to a blockage of wood debris. Atree had fallen, damaging the manhole and allowing branches and
other debris to enterthe system. Water and Sewer Maintenance staff responded by using high-pressure jetand
vacuum to remove the blockage from the manhole and cleaning the lines with a jet truck. The creek was flushed
using a nearby hydrant (dechlorinated) and the untreated wastewater was pumped back into the collections
system.
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 occurred.
As required, a news release was issued within the 24-hour window. The cost to remediate this spill by the City of
Durham was$3,963.22.
Incident# 202002500 — 2806 Snowhili Road —August 27 2020
On August 2-ph a section of sewerforce main located at 2806 Snowhill Road failed due to a buildup of gases in the
line. An estimated 6000 gallons of untreated wastewater flowed through a ditch into a 1-acre farm pond that
ultimately flows into an unnamed tributary of Little River. Waterand Sewer Maintenance (WSM) and Lift Station
Maintenance staff responded to the site, shut down the Snow Hill pump station and used fourJet Vac Trucks to
continuously pump out the wet well to keep the pumps from coming on while WSM Excavation crews attempted
repairs. City crews determined there were multiple failures in the pipe and a contractor would be needed to make
a permanent repair. Using a nearby hydrant, Waterand Sewer Maintenance crews flushed the affected ditch with
dechlorinated waterand setup a 6-inch pump downstream of the pond to return the untreated wastewater back
into the sewerforce main.
The Department's Utility Engine eringstaff contacted the 0n-Ca11 contractor - Carolina Civil Works (CCW) - for
assistance to make a permanent pipeline replacement. Within 48 hours of the initial event, CCW had mobilized
and setup a by-pass to allow for the re place me nt of approximately 1, 160 fe et of 12"- in ch pipe.
The City's StormwaterServices 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 occurred.
As required, a news release was issued within the 24-hour window. The cost to remediate this spill by the City of
Durham was $16,947.53. Contractor costs were $221,830.84 fora total cost of $238,778.37.
On oin City -Wide Measuresto Reduce the Occurrence of SSOs
The City has several programs in place to reduce and/or prevent the occurrence ofSSOs. 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 sewercollection system. The City is completingthe 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. For the FY 2021 year to date, the
City has cleaned 2.41% of the system. As operations normalize post-Covid-19, staff will dedicate more time to
this program.

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'ssystem rehabilitation
programs in the Utility Engineering Division of DWM. This workgroup handles flow monitoring and system
data managementand contract preparation, administration and inspections. There are 21 employee positions
in our Collections Systems Maintenance workgroup in the Water & Sewer Maintenance (WSM) Division of
DWM. This group performs CCTV inspections, hydrauliccleaning activities, mowing and manhole inspection
and repair. They respond to blockages and overflows. WSM does contract inspections as well. In addition,
crews from the Main Line workgroup of WSM perform point repairs, line replacements and some 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 14-
memberwork group 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 apart 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 a
numberof communityevents (Earth Day, CenterFest, and Landlord Workshops) as well as neighborhood
meetings to increase awareness of what is appropriate to put in the sewersystem. 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.) regardingthe properdisposal of FOG.
Summary:
Based upon the documented information provided above regarding these incidents, the City believes that
overflows 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 all
the requirements of the Collection System permit. As detailed above, the City systematically inspects, flushes and
rehabilitates its wastewater collection system. The department works actively to educate the community
regarding what should and should not be discharged into the City's sewercollection system.
Department staff welcomes the opportunity to meet with you and yourstaff 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] orvia email at
[e-mail].

For Immediate Release: August 28, 2020
City of Durham Contains Two Unrelated Sewer Spills
DURHAM, N.C. —The City of Durham Department of Water Management reports that on August 27, 2020, staff
responded to a pair of unrelated sanitary sewer overflows. The first was reported at 9:30 am when a force main fai
at 2806 Snow Hill Road. Approximately 6,000 gallons of untreated wastewater was released into a large field adjac

to the site. Crews shut down the pumps at the lift station to contain the spill and remained on site to make tempo
repairs the broken main. A contractor has been mobilized to make permanent repairs to the main.
Crews responded to the second overflow at 1:32 pm, finding a dead tree on top of a manhole at Stadium Drive and
Woodgreen Drive. The tree dislodged the manhole casting allowing debris to fall into the open manhole causing th
release of 645 gallons of untreated wastewater into a tributary of Warren Creek. The spill was contained at 2:1.
Crews jetted the main, remediated the spill site, dammed the creek downstream, flushed the creek, and pumped t
untreated wastewater back into the sanitary sewer system.
There were no observed hazards to persons or property as a result of either event. The N.C. Department of
