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-
215AC(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
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 with checklist 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 applicable design calculations including pipe and pump sizing,
velocity, pump cycle times, and level control settings, pump station buoyancy, wet well
storage, surge protection, detention time in the wet well, and force main, ability to flush low
points in force mains with a pump cycle, and downstream sewer capacity analysis. If a
portable power source or pump is dedicated to multiple stations, an evaluation of all the
pump stations' storage capacities and the rotation schedule of the portable power source or
pump, include travel timeframes, shall be provided.
c. 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.

DocuSign Envelope ID: 3E7EO4F3-EF71-4440-AOA7-5B5857OBD34D
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 .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 .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 maybe
required by the Division or any other Federal, State, of Local government agencies. [G.S. 143-
