Right-of-ways and easements shall be maintained in the full easement width for personnel and equipment
accessibility.
Documentation shall be kept for Subparagraphs (a) through (i) of this Rule for a minimum of three years
with exception of the map, which shall be maintained for the life of the system.
5. Noncompliance Notification:
The Permittee shall report by telephone to a water resources staff member at the Asheville Regional Office,
telephone number 828-296-4500, as soon as possible, but in no case more than 24 hours or on the next
working day, following the occurrence or first knowledge of the occurrence of either of the following:
a. Any process unit failure, due to known or unknown reasons, that renders the facility incapable of
adequate wastewater transport, such as mechanical or electrical failures of pumps, line blockage or
breakage, etc.; or
b. Any SSO and/or spill over 1,000 gallons; or
c. Any SSO and/or spill, regardless of volume, that reaches surface water
Voice mail messages or faxed information is permissible, but this shall not be considered as the initial verbal
report. Overflows and spills occurring outside normal business hours may also be reported to the Division of
Emergency Management at telephone number (800) 858-0368 or (919) 733-3300. Persons reporting any of
the above occurrences shall file a spill report by completing and submitting Part I of Form CS-SSO (or the most
current Division approved form) within five days following first knowledge of the occurrence. This report must
outline the actions taken or proposed to be taken to ensure that the problem does not recur. Part II of Form
CS-SSO (or the most current Division approved form) can also be completed to show that the SSO was beyond
control.
6. Construction of the gravity sewers, pump stations, and force mains shall be scheduled so as not to interrupt
service by the existing utilities nor result in an overflow or bypass discharge of wastewater to the surface
waters of the State.
Per 15A NCAC 2T.0116, upon completion of construction and prior to operation of these permitted facilities,
the completed Engineering Certification form attached to this permit shall be submitted with the required
supporting documents to the address provided on the form. A complete certification is one where the form is
fully executed and the supporting documents are provided as applicable. Any wastewater flow made tributary
to the wastewater collection system extension prior to completion of this Engineer's Certification shall be
considered a violation of the permit and shall subject the Permittee to appropriate enforcement actions.
If the permit is issued to a private entity with an Operational Agreement, then a copy of the Articles of
Incorporation, Declarations/Covenants/Restrictions, and Bylaws that have been appropriately filed with the
applicable County's Register of Deeds office shall be submitted with the certification.
A complete certification is one where the form is fully executed and the supporting documents are provided as
applicable. Supporting documentation shall include the following:
a. One copy of the project construction record drawings (plan & profile views of sewer lines & force mains)
of the wastewater collection system extension. Final record drawings should be clear on the plans or on
digital media (CD or DVD disk) and are defined as the design drawings that are marked up or annotated
with after construction information and show required buffers, separation distances, material changes,
etc.
b. One copy of the supporting pump station design calculations (selected pumps, system curve, operating
point, buoyancy calculations, available storage if portable generator(s) or storage greater than longest
past three year outage reliability option selected) for any pump stations permitted as part of this project.
Changes to the project that do not result in non-compliance with this permit, regulations, or the Minimum
Design Criteria should be clearly identified on the record drawings, on the certification in the space
provided, or in written summary form.
Prior to Certification (Final or Partial): Permit modifications are required for any changes resulting in non-
compliance with this permit (including pipe length increases of 10% or greater, increased flow, pump station
design capacity design increases of 5% or greater, and increases in the number/type of connections),
regulations, or the Minimum Design Criteria. Requested modifications or variances to the Minimum Design
Criteria will be reviewed on a case -by -case basis and each on its own merit. Please note that variances to the
Minimum Design Criteria should be requested and approved during the permitting process prior to
construction. After -construction requests are discouraged by the Division and may not be approved, thus
requiring replacement or repair prior to certification & activation.
8. A copy of the construction record drawings shall be maintained on file by the Permittee for the life of the
wastewater collection facilities.
Failure to abide by the conditions and limitations contained in this permit; 15A NCAC 2T; the Division's Gravity
Sewer Design Criteria adopted February 12, 1996 as applicable; the Division's Minimum Design Criteria for the
Fast -Track Permitting of Pump Station and Force Mains adopted June 1, 2000 as applicable; and other
supporting materials may subject the Permittee to an enforcement action by the Division, in accordance with
North Carolina General Statutes §143-215.6A through §143-215.6C, construction of additional or replacement
wastewater collection facilities, and/or referral of the North Carolina -licensed Professional Engineer to the
licensing board.
10. In the event that the wastewater collection facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as may be required
by this Division, such as the construction of additional or replacement facilities.

In accordance with your application received May 19, 2017, we are forwarding herewith Permit No.
WQCS00158, dated June 9, 2017, to the Town of Robbinsville for the operation and maintenance of the
subject wastewater collection system.
This permit shall be effective from June 9, 2017 until February 28, 2025 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 anyspecial conditions.
Changes have been made to the boiler plate language of the permit. Mostoftne 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
rulemaking-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 tratment facilities is referred to herein as a Sanitary Sewer Overflow (S5O). 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 apr;ropriate
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.). 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:

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 subm itted 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 thatthe 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 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC

In accordance with your application received May 19, 2017, we are forwarding herewith Permit No.
WQCS00158, dated June 9, 2017, to the Town of Robbinsville for the operation and maintenance of the
subject wastewater collection system.
This permit shall be effective from June 9, 2017 until February 28, 2025 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 anyspecial conditions.
Changes have been made to the boiler plate language of the permit. Mostoftne 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
rulemaking-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.

Robbinsville Collection System
June 9, 2017
A discharge of wastewater to the environment from the Permittee's wastewater collection system prior to
reaching the wastewater tratment facilities is referred to herein as a Sanitary Sewer Overflow (S5O). 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 apr;ropriate
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.). 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:

550(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 subm itted 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 thatthe 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 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC

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 .0108 (b)]
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
