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. [G.S. 143-
215.1C(a1)]
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

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.
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.
Page 6 of 9

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. [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 .0104; 15A NCAC 02T .0108(b -c)]
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 .0108(b)]
12. The issuance of this permit shall not exempt the Permittee from complying with any and all statutes,
rulesI regulations, or ordinances that may be imposed by the Division any other Federal, State, or

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
provide 24 -hours' worth of wastewater storage or,p exceed the greatest power outage
over the last three years or the documented response time to replace a failed pump,
