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(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

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.
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 .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. 143-215.1(b)]
