Dear Mr. Shearin:
In accordance with your permit modification application received March 13, 2002, and subsequent
additional information received September 4, 2002, and November 5, 2002 we are forwarding herewith Permit
No. WQ0016366 dated December 20, 2002, to Charlotte Mecklenburg Utilities for the construction and continued
operation of the subject wastewater collection extension. This permit shall be effective from the date of issuance
until rescinded, shall void Permit No. WQ0016366 issued August 29, 2001, and shall be subject to the conditions
and Iimitations as specified therein.
Please 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 Permtttee.
In the permit issued August 29, 2001, conditions 6, 8, and 12(e) were modified for the whispering Oaks
Drive portion of the project. These conditions have been placed at the end of this permit as Conditions 18 - 20
and are still applicable to that part of the project.
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 150B of North Carolina General Statutes, and
filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699-6714. Unless

7. Upon completion of construction and prior to operation of these permitted facilities, a certification and a copy
of the construction record drawings shall be received from a North Carolina -licensed Professional Engineer
certifying that the facilities have been installed in accordance with this permit; 15A NCAC 2H .0200; the

their options explained (STEP system vs. grinder pump). If the homeowner chooses to keep the existing
septic tank and implement a STEP system, an effluent pump will be an acceptable selection for connection to
the pressure sewer system. If the conventional septic system is completely abandoned, a grinder pump is the
only acceptable pump to install for connection to the pressure system.
12. The Permittee shall provide information about the proper operating head conditions applicable to the
homeowner's specific lot to the homeowner and the selected plumbing contractor upon request for connection
to the system. Other pertinent information required for the proper selection and installation of the pump

the Permittee .response time for service or the Iongest non -catastrophic power outage of the previous
three years for any simplex pump station serving a single family residence.
b. A screened vent for the wet well.
c. Fillets located in the wet well(s) at the intersection of the flooring and side walls.
d. Sufficient devices which will protect the pump station from vandals.
e. Flood protection if the pump station is located below the 100-year flood elevation.
f. Audible and visual high water alarms.
g. Anti -flotation for the pump station. Buoyancy calculations for the selected pump stations must be
completed prior to the release of the final design documents for installation to insure flotation of the
pump station will not occur in submerged conditions.
h. Each pump station shall be clearly and conspicuously posted with the telephone number of the
owner/operator of the pressure sewer system and instructions to call the number in the event of high
water alarm activation.

13. The permittee shall provide the following for the force main:
a. An air relief valve located at all high points along the force main.
b. Three feet of cover (minimum) over the force main or the use of ferrous material where three feet cannot

tide elevation)] 50 feet
(vi) Any other stream, lake or impoundment 10 feet
(vii) Any building foundation 5 feet
(viii) Any basement 10 feet

(xi) Any swimming pool 10 feet
(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;
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 as "high priority" until such time as the
contributing flow provides a velocity exceeding 2 feet per second. High priority lines must be inspected
every six months and cleaned as necessary. These lines 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 pipe (DIP) and service lines routed beyond the encasement
where the sewer line must be placed within the 100 foot radius of only one well. I case of multiple wells
where radii overlap and DIP is not available, SDR 13.5 PVC 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 Ietter
of 4/13/2000).. For Whispering Oaks Drive only, since only one_ well is shown, the plans shall be modified to
reflect DIP encasement and not SDR 13.5 PVC pipe as shown.
4

The following conditions apply to the Whispering Oaks Drive portion of this permit.
18. Calculations completed before the release of final design documents for installation shall indicate that the
downstream sewer has adequate capacity to accept the new wastewater flows expected from this project.
19. The final specifications shall indicate that the leakage test pressure shall be maintained for two hours.
20. 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 the flood elevation or by providing a water tight tank with the vent and
all other external controls extending at least two feet above the flood elevation.
