SUPPLEMENT TO PERMIT COVER SHEET

Town of Pittsboro is hereby authorized to:

Construct, and then operate upon certification the aforementioned wastewater collection extension. The
sewage and wastewater collected by this system shall be treated in the Town of Pittsboro’s Wastewater
Treatment Facility in accordance with Permit Number NC0020354.

Permitting of this project does not constitute an acceptance of any part of the project that does not meet
15A NCAC 02T; the Division’s Gravity Sewer Minimum Design Criteria adopted February 12, 1996 as
applicable; and the Division’s Minimum Design Criteria for the Fast-Track Permitting of Pump Stations and

h. A Grease Control Program is in place as follows:
1. For public owned collection systems, the Grease Control Program shall include at least
biannual distribution of educational materials for both commercial and residential users and
the legal means to require grease interceptors at existing establishments. The plan shall also

sewer systems.
2. For privately owned collection systems, the Grease Control Program shall include at least bi-
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)

the Division of Emergency Management at telephone number [phone] or [phone].
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 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
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 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 individual permit and 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 02T; 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 .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)]
