wastewater collection system extension. This permit shall be effective from the date of issuance until
rescinded and shall be subject to the conditions and limitations as specified therein. This cover letter
and supplement shall be considered a part of this permit and are therefore incorporated therein by
reference.
Please pay particular attention to the following conditions contained within this permit:
Condition 1.1: All low pressure sewers, pressure service laterals and grinder pump stations shall be
installed outside of the 50-foot buffer of Lake Wylie (Class WS-IV), per 15A NCAC 2T
.305(f) and the provided plans.
Condition 1.2: Minimum separation for all low pressure sewers shall not be less than 25 feet from

appurtenances shall remain outside of the 100-foot radius of well in accordance with
15A NCAC 02T.0305(g).
Condition 1.6 The Permittee shall be responsible for all individual pumps, tanks, service laterals and
main lines as permitted. This does not prohibit the Permittee from entering into a
service agreement (as submitted in the permit application supporting document
package) with another entity for maintenance or operation of these units, however, the
Permittee shall be responsible for correcting any environmental or public health
problem with the system and bears the ultimate responsibility for ensuring these units
are maintained in operable condition. [15A NCAC 02T.0304(c)]

Regional Office, telephone number [phone], as soon as possible, but in no case more than 24
hours, 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 [phone] 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 11 of Form CS-SSO (or the most current
Division approved form) can also be completed to show that the SSO was beyond control. [G.S. 143-
215.IC(al)]
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. [15A NCAC 02T.0108(b)]
7. 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.
Page 6 of 9

DocuSign Envelope ID: 08D3CEC5-578C-4199-Al96-59308DA27732
if the permit is issued to a private entity with an Operational Agreement, then a copy of the
Articles of Incorporation, Dec I a rations/Coven a nts/Restricti on s, 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. 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 but not limited to pipe length changes 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. [15A NCAC 02T .0116]
8. Gravity sewers installed greater than ten percent below the minimum required slope per the
Division's Gravity Sewer Minimum Design Criteria shall not be acceptable and shall not be certified
until corrected. If there is an unforeseen obstacle in the field where all viable solutions have been
examined, a slope variance can be requested from the Division with firm supporting documentation.
This shall be done through a permit modification with fee. Such variance requests will be evaluated
on a case -by -case basis. Resolution of such request shall be evident prior to completing and
submitting the construction certification. [ 15A NCAC 02T.0105(n)]
9. A copy of the construction record drawings shall be maintained on file by the Permittee for the life
of the wastewater collection facilities. [15A NCAC 02T.0116]
10. 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. [15A
NCAC 02T.0108(b-c)]
Page 7 of 9

DocuSign Envelope ID: 08D3CEC5-578C-4199-Al96-59308DA27732
11. 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. [15A NCAC 02T.0110; 15A NCAC 02T.0108(b)]
12. The issuance of this permit shall not exempt the Permittee from complying with any and all statutes,
rules, regulations, or ordinances that may be imposed by the Division any other Federal, State, or
Local government agencies which have jurisdiction or obtaining other permits which may be
required by the Division or any other Federal, State, of Local government agencies. [G.S.143-
215.1(b)]

provided to automatically activate the standby source and signal an alarm condition.
3. As an alternative to Part (c) for pump stations with an average daily design flow less
than 15,000 gallons per day as calculated using 15A NCAC 02T.0114, a portable power
source or pumping capability may be utilized. It shall be demonstrated to the Division
that the portable source is owned or contracted by the permittee and is compatible
with the station. if the portable power source or pump is dedicated to multiple pump
stations, an evaluation of all the pump stations' storage capacities and the rotation
schedule of the portable power source or pump, including travel timeframes, shall be
provided in the case of a multiple station power outage.
4. As an alternative to Part (ii) for pump or vacuum stations connecting a single building to
an alternative sewer system, wet well storage requirements shall be documented to
