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 [phone].

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

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

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, including 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°Y or greater, and increases in the number/type of
Page 6 of 8

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 .01161
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 priorto completing and submitting
the construction certification. [ 15A NCAC 02T.0105(n)]

the wastewater collection facilities. [15A NCAC 02T .01161
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 and updated March 2008,
as applicable; the Division's Minimum Design Criteria for the Fast -Track Permitting of Pump Station
and Force Mains adopted June 1, 2000 and updated March 2008 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)1
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)]
