annual distribution of grease education materials to users of the collection system by the
permittee or its representative.
3. Grease education materials shall be distributed more often than required in Parts (1) and (2)
of this Subparagraph if necessary to prevent grease -related sanitary sewer overflows.
i. Right-of-ways and easements shall be maintained in the full easement width for personnel and
equipment accessibility.
j. Documentation shall be kept for Subparagraphs (a) through (i) of this Rule fora minimum of three
years with exception of the map, which shall be maintained for the life of the system.

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
Page 6 of 8
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 (800) 858-0368 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. 143-215.1C(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
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.
Prior to Certification (Final or Partial): Permit modifications are required for any changes resulting
in non-compliance with this permit (including 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
Page 7 of 8
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 may be required by
the Division or any other Federal, State, of Local government agencies. [G.S. 143-215.1(b)]
