Triangle Wastewater Treatment Plant Collection System
Durham County
Dear Mr. Worsley:
In accordance with your permit application received July 15, 2014, we are forwarding herewith
Permit No. WQCS00038, dated September 7, 2016, to the Durham County for the operation and
maintenance of the subject wastewater collection system.
This permit shall be effective from September 7, 2016, until January 31, 2020 and shall be
subject to the conditions and limitations specified herein. It is your responsibility to thoroughly
review this pemrit. Please pay particular attention to the monitoring and reporting requirements
in this permit and any compliance schedules shown in bold.
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 release of wastewater from the wastewater collection system is referred to herein as a Sanitary
Sewer Overflow(SSO). The evaluation of enforcement options after an SSO,will be determined
considering the criteria listed in condition I(3)(a) and I(3)(b) of the permit and all other 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 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 SSO of any amount
that reaches surface water(including through ditches, storm drains, etc.) Below is the procedure
to use for reporting SSOs to the Division:
1. Report by telephone to a Division of Water Resources (DWR) staff member (not email,
facsimile, or voicemail) at your regional DWR office during regular business hours
(Monday to Friday, 8AM to 5PM) as soon as possible, but in no case more than 24 hours
after the SSO is-known or discovered. To report outside of regular business hours, call
[phone].
2. Follow up the verbal report by sending a completed written report on the most current
Division approved form within five days.
To provide a uniform method for all systems covered under this permit and to provide useful and
consistent information pertaining to SSOs, please utilize form CS-SSO consisting of two parts.
Part I serves to provide to the Division the required information that has always been necessary.
Part II serves as an area to provide a justification for the spill, as optional under Condition I(3) of
your permit. Form CS-SSO can be downloaded from the SSO Reporting area at
http://portal.nedenr.org/web/wq/swp/ps/cs/ssorenort.
An 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 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. Begin using this form immediately to report SSOs from the collection
system. Continue to use our old form for reporting bypasses at the wastewater treatment plant
until further notice. The time frame for submittal of both Part I and Part II, if pertinent, is five
days.
Failure to abide by the conditions in this permit may subject the Permittee to enforcement action.
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 150B 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.

ENVIRONMENTAL MANAGEMENT COMMISSION
DEPARTMENT OF ENVIRONMENTAL QUALITY
RALEIGH
SYSTEM-WIDE WASTEWATER COLLECTION SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of
North Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Durham County
Durham County
FOR THE
operation and maintenance of a wastewater collection system consisting of, at the time of permit
issuance, approximately 94.9 miles of gravity sewer, approximately 8.8 miles of force main, 12
duplex pump stations, and all associated piping, valves, and appurtenances required to make a
complete and operational wastewater collection system, pursuant to the permit application
received July 15, 2014, and in conformity with the documents referenced therein and other
supporting data subsequently filed and approved by the Department of Environment Quality.and
considered a part of this permit. Other satellite wastewater collection systems, operated and -
maintained by others, are tributary to this collection system and include a portion 'of the City of
Durham wastewater collection system and several deemed permitted wastewater collection
systems. The wastewater.collected by this system shall be treated in the Triangle Wastewater
Treatment Plant.
This permit shall be effective from September 7, 2016 until January 31, 2020, and shall be
subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. The wastewater collection system shall be effectively managed, maintained and
operated at all times. [15A NCAC 02T .0108(b)]
2. The Director may take enforcement action against the Permittee for SSOs that must be
reported to the Division as stipulated in Condition IV(2). This includes SSOs that were
caused by severe natural conditions or exceptional events unless the Permittee
demonstrates through properly signed, contemporaneous operating logs, or other
relevant evidence that:

a. The SSO was caused by severe natural conditions; there were no feasible
alternatives to the SSO, such as the use of auxiliary treatment facilities, retention
of untreated wastewater, reduction of inflow and infiltration, use of adequate
back-,up equipment, or an increase in the capacity of the system. This provision
is not satisfied if, in the exercise of reasonable engineering judgment, the
Permittee should have installed auxiliary or additional collection system
components, wastewater retention or treatment facilities, adequate back-up
equipment or should have reduced inflow and infiltration; or
b. The SSO was exceptional, unintentional, temporary and caused by factors
beyond the reasonable control of the Permittee; the SSO could not have been
prevented by the exercise of reasonable control, such as proper management,
operation and maintenance; adequate treatment facilities or collection system
facilities or components (e.g., adequately enlarging treatment or collection
facilities to accommodate growth or adequately controlling and preventing
infiltration and inflow); preventive maintenance; or installation of adequate back-
up equipment;
The Permittee can submit a claim to the Division Regional Office that the SSO meets the
criteria of this condition. The Permittee has the option of submitting this claim along with
the spill report required by Condition IV(2) (i.e., within five business days) in order to be
considered for immunity from enforcement action. Form CS-SSO Part II, or most current
Division approved form, shall be used for any claims. The Permittee has the burden of
proof that the above criteria have been met. [G.S. 215.6A; 15A NCAC 02T .0108(b)]
3. The Permittee shall establish by ordinance, interlocal agreement or contract its legal.
authority to require new sewers be properly constructed; to ensure proper inspection and
testing of sewer mains and connections thereto; to address flows from satellite systems
and to take enforcement action as required by Condition 1(4). [G.S. 143-215.9B; G.S.
143-215.1(f)(1)]
4. The Permittee shall develop and implement an educational fats, oils and grease program
that shall include at least semiannual distribution of educational material targeted at both
residential and non-residential users. The Permittee shall also develop and implement
by ordinance or contract an enforceable fats, oils and grease program for non-
residential users under which the Permittee can take enforcement against users who
have not properly installed, operated and maintained grease traps or grease interceptors
as directed or otherwise violated the terms of the enforcement program pertaining -to
fats, oils and grease. [15A NCAC 02T .0108(b)]
5. The Permittee shall adopt and implement a Capital Improvement Plan (CIP) to designate
funding for reinvestment into the wastewater collection system infrastructure. The CIP
should address the short-term needs and long-term "master plan" concepts. The CIP
should typically cover a three to five year period and include a goal statement,
description of the project area, description of the existing facilities, known deficiencies
(over a reasonable period) and forecasted future needs. Cost analysis is integral to the
CIP. [G.S. 143-215.913
6. Overflow piping from manholes and pump stations, excluding piping to approved
equalization structures, known or discovered after permit issuance shall be immediately
removed or permanently capped. Plugged or valved emergency pumping connections
are allowable for portable pumping or rerouting without intentionally bypassing the
wastewater treatment facility. [15A NCAC 02T .0305(d)]

7. The Permittee shall maintain a contingency plan for pump failure at each pump station:
If one of the pumps in a pump station containing multiple pumps fails, the process of
repairing or replacing the pump shall be initiated immediately and the new parts or pump
shall be installed as soon as possible. The Permittee shall provide justification for delay
in initiating the process for repair or replacement at the Division's request. If the pump in
a simplex pump station serving more than a single building or pump station not capable
of pumping at a rate of 2.5 times the average daily flow rate with the largest pump out of
service fails, it shall be replaced immediately. [15A NCAC 02T .0305(h)(1)]
8. Each pump station shall be clearly and conspicuously posted with a pump station
identifier and an emergency contact telephone number at which an individual who can
initiate or perform emergency service for the wastewater collection system 24 hours per
day, seven days per week can be contacted. This emergency contact telephone number
shall be coupled with instructions that the emergency contact should be called if the
visual alarm illuminates, if the audible alarm sounds, or if an emergency is apparent.
[15A NCAC 02T .0305(h)(2)]
9. Pump station sites, equipment and components shall have restricted access. [15A
NCAC 02T .305(h)(4)]
10. Pump stations that do not employ an automatic polling feature (i.e. routine contact with
pump stations from a central location to check operational status of the communication
system) shall have both audible and visual high water alarms. The alarms shall be
weather-proof and placed in a clear and conspicuous location. Permits issued for the
construction of pump stations that included high water alarms in the description must
maintain the alarms even if simple telemetry (i.e. notification of an alarm condition
initiated by the pump station control feature) is installed. [15A NCAC 02T .0305(h)(1)]
11. For all newly constructed, modified and rehabilitated pump stations, material selection
shall address installation and operating factors such as physical, chemical and biological
wastewater characteristics, corrosive gas production, soil characteristic and groundwater
presence. [15A NCAC 02T .0108(b)]

Operators Certification Commission (WPCSOCC), the Permittee shall designate and
employ a certified operator to. be in responsible charge (ORC) and one or more certified
operator(s) to be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G
.0201. The ORC shall visit the system within 24 hours of knowledge of a bypass, spill,
or overflow of wastewater from the system, unless visited by the Back-Up ORC, and
shall comply with all other conditions of 15A NCAC 8G .0204. 115A NCAC 08G .0200
et.seq.]
2. The Permittee shall develop and adhere to a schedule for reviewing all inspection,
Maintenance, operational and complaint logs. If the review process results in the
identification of any recurring problem in the wastewater collection system that cannot be
resolved in a short time period, the Permittee shall establish a plan for addressing the
problem(s). [15A NCAC 02T .0108 (b)]

within the storage capacity provided in a sewer line extension permit. [15A NCAC 02T
.0108 (b)]
7. Rights-of-way and/or easements shall be properly maintained to allow accessibility to the
wastewater collection system unless the Permittee can demonstrate the ability to gain
temporary access in an emergency situation where existing land-use conditions do not
allow the establishment and maintenance of permanent access. In this case, the
Permittee shall continue to observe the lines visually, utilize remote inspection methods
(e.g.. CCTV) and use the opportunity of drier conditions to perform further inspections
and necessary maintenance. [15A NCAC 02T .0108 (b)]
8. The Permittee shall assess cleaning needs, and develop and implement a program for
appropriately'cleaning, whether by hydraulic or mechanical methods, the wastewater
collection system. At least 10 percent of the gravity wastewater collection system,
selected at the discretion of the ORC, shall be cleaned each year. Preventative cleaning
is not required for sewer lines less than five years old unless inspection otherwise
