Dear Mr, Greeley:

cio.g
LF--47,2.2-,4_02-,
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 S50 (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:

This Notice of Violation / Notice of Intent to Enforce (NOV/NOI) is being issued for the noted violation. Pursuant
:o G.S. 143-2.15.6A, 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
iermit 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.

Dear Mr. Vinson,

JUL 15 Ztld
Raleigh Regional Otis
This letter is in response toyour notice dated May 20, 2021 which was received by the City of Durham on June 29,
2021. The May 20, 2021 Ietterstatesthat 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 forthe sanitary sewer overflows (SSOs) which occurred in the City's sewer collection system between
April 1, 2021 and April 30, 2021.
As requested, the City of Durham, Department of Water Management (DWM) is providing information about the
two inddents which occurred during this 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, temporary and beyond the City's exercise of reasonable control.
Incident# 202101195 — 9 Yarmouth Place —April 17, 2021
On April 17, 2021 manhole #04057 at 9 Yarmouth Place overflowed, with an estimated 1,000 gallons of
wastewaterdischarging into New Hope Creek. This overflow occurred due to a blockage in the sewer main caused
by roots. Water and Sewer Maintenance staff used a high-pressure jet and a root cutter to remove the blockage
from the main, cleaning the lines with a VAC ALLoombo truck. The creek was dammed and then flushed using a
nearby hydrant (dechlorinated) and the untreated wastewater was pumped back into the sanitary sewersystem
(4" pump used).
The City's Stormwate rSe rvices Division responded and conducted ammonia testing to help determine the extent
of the spill and to advise when the site retumed to normal conditions. No immediately visible adverse
environmental impacts or hazards to persons or property occurred. Staff will continue to monitorthis portion of
the collection system for root intrusion and if the roots become an ongoing issue, the area will be included in the
City's root control contract.
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
$5,719.53.
Incident* 202101217 —1010 Grant Street— April 22i 2021
On April 22, 2021, Water and Sewer Maintenance crews were called to an incident at 1010 Grant Street by a City
contractor who discovered a blockage on a main caused by grease. As staff investigated further, they found a pipe

Page 2 of 3
failure allowing wastewaterto leak into the stream. The pipe failure had occurred due to a large tree branch falling
on the pipe, damaging the topside of the exposed pipe. Temporary repairs were made at the location by replacing
the existingductile iron pipe with 9 linear feet of 12-inch ductile iron pipe. The department's Utility Engineering
will be working with a contractor to make permanent repairs. The creekwas dammed and then flushed using a
nearby hydrant (dechlorinated) and the untreated wastewater was pumped back into the sanitary sewer system
(4" pump used).
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. Departmental public information staff
provided information regarding the properdisposal of grease via social media and IWC/FOG staff distributed
educational materials in the neighborhood.
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
$7,300.80.
OngoinRCity-Wide Measures to Reduce the Occurrence of SSOs
The City has several programs in place to reduce and/orprevent 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 1O% 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 12.08% 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 Tine 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 21 employee positions
in our Collections Systems Maintenance workgroup in the Water & Sewer Maintenance (WSM) Division of
DWM. This group performs CCTV inspections, hydraulicdeaning 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 UftStation 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 assodated 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 workingdosely with the

Page 3 of 3
Durham County Health Department, staff routinely inspect over 800 food service establishments (FSEs)
annually to ensure appropriate cleaningand maintenance of grease interceptors. Staff participates in a
number of community events (Earth Day, CenterFest, 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 believesthat
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 sewer collection system.
Department staff welcomes the opportunity to meet with you and your staff to review ourprogram 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

Dear Mr. Greeley:
NORTH CAROLINA
Environmental Quality
August 16, 2018
In accordance with your application received August 9, 2018, we are forwarding herewith Permit No. WQCS00005,
dated August 16, 2018, to the City of Durham for the operation and maintenance of the subject wastewater collection
system.
This permit shall be effective from August 16, 2018 until July 31, 2026 and shall be subject to the conditions and
limitations specified herein. It is your responsibility to thoroughly review this permit. Please pay particular attention
to the monitoring and reporting requirements in this permit and any special conditions.
Changes have been made to the boiler plate language of the permit. Most of the changes are for clarification
purposes, however Condition 1(3) has been removed. The Department of Environmental Quality (DEQ) believes
that condition was included erroneously in previous permits. It was included based on proposed ruiemaking by EPA
which was never promulgated and, in the continued absence of Federal regulations, DEQ lacks authority to include
such language in a permit. DEQ will continue to exercise enforcement discretion when evaluating sanitary sewer
overflows that may be considered to be beyond the reasonable control of the Permittee. A highlighted copy of the
permit identifying the changes made is available at:

For purposes of permitting, the collection system is considered to be any existing or newly installed system
extension up to the wastewater treatment facility property or point of connection with a separately owned sewer
system. The collection system is considered all gravity lines, pump stations, force mains, low pressure sewer
systems, STEP systems, vacuum systems, etc. and associated piping, valves and appurtenances that help to collect,

manage and transport wastewater to a wastewater treatment plant under the Permittee's ownership or
maintained and operated by the Permittee through a perpetual legal agreement. Satellite systems are systems
tributary to the Permittee's collection system but those collection systems are not owned or maintained by the
Permittee. The system description provided on Page 1 of this permit Is meant to provide a general idea about the
size of the system and may not be all inclusive of the collection system at the time of permit issuance or afterward.
A discharge of wastewater to the environment from the Permittee's wastewater collection system prior to reaching
the wastewater treatment facilities is referred to herein as a Sanitary Sewer Overflow (SSO). The evaluation of
enforcement options after an SSO will be determined considering all relevant information available or requested of
the Permittee Compliance with all conditions of the permit as well as all statutes and regulations pertaining to the
wastewater collection system must be maintained or appropriate enforcement actions may be taken as noted in
Condition VI (2).
A reportable SSO is an SSO greater than 1,000 gallons to the ground or an S50 of any amount that reaches surface
water (including through ditches, storm drains, etc.). Reporting requirements including the required verbal report
and written report to the appropriate regional office are referenced in Condition IV (2). Form CS-SSO can be
downloaded from the SSO Reporting area at:

public/Water9620Qua1ity/Surface%20Water%20Protectton/PE RCS/WCS%20(SSO%20Docu mentsj/CS-
SSO(2015).doc.
A notice of deficiency (NOD), notice of violation (NOV), civil penalty, and/or a moratorium on the addition of waste
to the system may be issued if adequate justification for an SSO is NOT submitted to the regional office. In order to
submit a claim for justification of an SSO, you must use Part II of form CS-SSO with additional documentation as
necessary. DWR staff will review the justification claim and determine if enforcement action is appropriate. Please
be advised that the information needed to justify a spill Is very comprehensive.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing upon written request within thirty days following the receipt of this permit. This request must
be in the form of a written petition, conforming to Chapter 15013 of the North Carolina General Statutes, and filed
with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699-6714. Unless such
demands are made, this permit shall be final and binding.
If you have questions regarding compliance, contact the appropriate regional office. If you need additional
information concerning this permit, please contact Gwyn Ann McCullough at [phone].
Sincerely,
Aken-ksi.
