SUPPLEMENT TO PERMIT COVER SHEET
Charlotte -Mecklenburg Utility Department 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 McAlpine Creek Wastewater
Treatment Plant in accordance with Permit Number NC0024970.
Permitting of this project does not constitute an acceptance of any part of the project that does not
meet 15A NCAC 2T; 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 Force Mains adopted June 1, 2000 as applicable, unless specifically mentioned herein. Division
approval is based on acceptance of the certification provided by a North Carolina -licensed Professional
Engineer in the application. It shall be the Permittee's responsibility to ensure that the as -constructed
project meets the appropriate design criteria and rules.
Construction and operation is contingent upon compliance with the Standard Conditions and any Special
Conditions identified below.
I. SPECIAL CONDITIONS
1. The portion of the project denoted as the "Westhall Gravity Sewer" shall be incorporated into the
Permittee's Preventative Maintenance schedule in accordance with Section V of the Individual
System -Wide Collection System Permit (WQCS00001). [15A NCAC 02T.0108]
I1. STANDARD CONDITIONS

other supporting materials as may be appropriate. The approval of this request shall be considered
on its merits and may or may not be approved. [15A NCAC 02T.0104]
2. This permit shall become voidable unless the wastewater collection facilities are constructed in
accordance with the conditions of this permit; 15A NCAC 2T; the Division's Gravity Sewer Minimum
Design Criteria adopted February 12, 1996 as applicable; the Division's Minimum Design Criteria for
the Fast -Track Permitting of Pump Stations and Force Mains adopted June 1, 2000 as applicable; and

Page 4 of 8
. Noncompliance Notification:
The Permittee shall report by telephone to a water resources staff member at the Mooresville
Regional Office, telephone number (704) 663-1699, as soon as possible, but in no case more than 24
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
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

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]
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.0403]
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 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.
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. 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,
Page 5 of 8
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. 115A 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. 115A 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
