CMU Project No. 379-00-609
Pressure Sewer Extension
Mecklenburg County
Dear Mr. Shearin:
In accordance with your permit modification application received May 31, 2001, we are forwarding
herewith Permit No. WQ0016366 dated August 29, 2001, to the Charlotte -Mecklenburg Utility Department
for the continued operation of the existing Nantz Road pressure sewer system (with corrected flow) and for
construction and operation of the Whispering Oaks Drive pressure sewer system extension. The sewer lines
in this project are also associated with Permit No. WQ0016555 and Permit No. WQ0016784 (same system).
The flow for the existing Nantz Road portion will be modified to reflect the correct number of lots served
for the portion of line installed for this permit. The initial permit application for this project identified flow
for total build -out of the system and not the portion of the project being constructed. Therefore, subsequent
permit applications for other portions of the system double accounted for flow. From now on, additional
flows will be allocated at the time new line is installed in the system. This permit shall be effective from
the date of issuance until rescinded, shall void Permit No. WQ0016366 issued on March 10, 1999, and shall
be subject to the conditions and limitations as specified therein, with the following special conditions
regarding the project design and/or specifications:
Condition 6: Construction of the pressure sewer system 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. Calculations completed before release of the final design documents for installation
shall indicate that the downstream sewer has adequate capacity to accept the new wastewater flows
anticipated for this project.
Condition 8: A copy of the approved plans and specifications shall be maintained on file by the
Permittee for the Iife of the wastewater collection facilities. The final specifications shall indicate that
leakage testing shall be maintained for two hours.
Condition 12(e): Flood protection if the pump station is located below the 100-year flood
elevation. All pump stations must be protected from the 100-year flood by installing the pump station
so that the top of the wet well is at least two feet above flood elevation or by providing a water tight
tank with the vent and all other external controls extending at least two feet above flood elevation.

Most top of wet well elevations were set right at the flood elevation in the submitted calculations. If
necessary, modify the tables shown in the plans for corrected elevations and other operating
parameters prior to the release of the final design documents for installation.
Condition 12(h): Anti -floatation for the pump station. Buoyancy calculations for the selected
pump stations must be completed before the release of the final design documents for installation to
ensure floatation of the pump station will not occur in submerged conditions.
Condition 17: The pressure sewer shall be encased in ductile iron (DIP) and the service lines
routed beyond the encasement where the pressure sewer line must be placed within the 100-foot
radius of only one well. In the case of multiple wells where radii overlap and ferrous pipe is not
available, SDR 13.5 pipe (for less than 4-inch diameter) may be used if tested to water main
stand rds with no leakage and marked with detector tape (per Division variance letter of 4/13/2000).
Since one well is shown in the project plans, the plans shall be modified to reflect DIP encasement.
The above bolded wording must be completed prior to the release of the final design documents for
installation of the system and certified as part of the Engineering Certification. Additionally, pay particular
attention to Permit Condition 3 which requires that the wastewater collection facilities be properly operated
and maintained in accordance with 15A NCAC 2H .0227 or any individual system -wide collection system
permit issued to the Pemiittee. It is also important to review the other permit conditions specific to this
system including Permit Conditions 11, 12 and 16, noted in bold throughout this permit.
Permitting of this project does not constitute an acceptance of any part of the project that does not
meet 15A NCAC 2H .0200; the Division of Water Quality's (Division) 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. Failure to comply
may result in penalties in accordance with North Carolina General Statute §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.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within 30 days following receipt of this
permit. This request must be in the form of a written petition, conforming to Chapter 15013 of North
Carolina General Statutes, and filed with the Office of Administrative Hearings. 6714 Mail Service Center,
Raleigh, NC 27699-6'714. Unless such demands are made this per ndt shall be final and binding.
One set of approved plans and specifications is being forwarded to you. If you need additional
information concerning this matter, please contact Marie Doklovic at (91 733-5083 extension 371.

(xii) Ferrous sewer pipe with joints equivalent to water main standards, shall be used where
these minimum separations cannot be maintained. The minimum separation shall however
not be less than 25 feet from a private well or 50 feet from a public water supply well;
4

14. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions, the Permittee shall take immediate corrective action, including those that may be required
by this Division, such as the construction of additional or replacement wastewater collection facilities.
15. Noncompliance Notification:
The Permittee shall report by telephone to the Mooresville Regional Office, telephone number (704)
663-1699, as soon as possible, but in no case more than 24 hours or on the next working day
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 render the facility incapable of
adequate wastewater transport such as mechanical or electrical failures of pumps, line blockage or
breakage, etc.
b. Any failure of a pumping station or sewer line resulting in a by-pass directly to receiving waters
without treatment of all or any portion of the influent to such station or facility.
Persons reporting such occurrences by telephone shall also file a written report in letter form within
five (5) 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.
16. The pressure sewer lines permitted herein shall be designated "high priority" until such time
that the contributing flow provides a velocity exceeding 2 feet per second. High priority lines
must be inspected once every six months and cleaned as necessary. This line will be included in
the Charlotte -Mecklenburg Utility Department individual collection system permit upon
issuance.
17. The pressure sewer shall be encased in ductile iron (DIP) and the service lines routed beyond
the encasement where the pressure sewer line must be placed within the 100-foot radius of only
one well. In the case of multiple wells where radii overlap and ferrous pipe is not available,
SDR 13.5 pipe (for less than 4-inch diameter) may be used if tested to water main standards
with no leakage and marked with detector tape (per Division variance letter of 4/13/2000).
Since one well is shown in the project plans, the plans shall be modified to reflect DIP
encasement and not SDR 13.5 PVC pipe as shown.
