In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina
as amended, and other applicable Laws, Rules, and Regulations, permission is hereby granted for the
.construction and operation of 247 linear feet of 8 inch gravity sewer, 5,266 linear feet of 18 inch gravity
sewer, 18,213 linear feet of 24 inch gravity sewer, 8,941 linear feet of 30 inch gravity sewer, 11,000
linear feet of 36 inch gravity sewer, 3,930 linear feet of 78 inch gravity sewer, a 12,500 gpm pump station
with three duty pumps and one stand-by pump, high water alarms, standby generator with automatic
transfer switch and approximately 423 linear feet of 30 inch force main to serve the Six Mile Creek Basin
with zero (0) additional gallons per day of collected domestic wastewater into the Charlotte Mecklenburg
Utilities existing sewerage system in conformity with 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

Environment and Natural Resources and considered a part of this permit.
The sewage and wastewater collected by this pump station shall be treated in the McAlpine
Creek WWTP (NPDES No. NC0024970) prior to being discharged into the receiving stream.
Assessing subsequent impacts to the downstream collection system is the complete
responsibility of Charlotte Mecklenburg Utilities. Charlotte Mecklenburg Utilities must utilize whatever
tracking tools necessary for planning additions of sewer flow in order to maintain compliance with the
WQCS00001 permit requirements.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the

blockage or breakage, etc.; or
2

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.
Voice mail messages or faxed information is permissible, but shall not be considered as the

Subject: CMU Six Mile Creek Pumping Station
Fast -Track Application
Dear Ms.. Browder:
136099-200/10
Enclosed are an original and a copy of the Fast -Track Application for the
modification to the Six Mile Creek Pumping Station (PS) owned and
operated by Charlotte Mecklenburg Utilities (CMU). Brown and Caldwell
was retained to provide the design, permitting, bidding and construction
administration for the upgrades to the existing Six Mile Creek PS.
The Six Mile Creek PS is located off of Marvin Road in southern
Mecklenburg County and serves the Six Mile Creek sewer basin. It was
originally built in the mid-1990s under permit WQ0010438 along with the
Six Mile Creek influent sewer and discharge force main and gravity sewer for
discharge at McAlpine Creek Wastewater Treatment Facility (NC0024970).
As stated in the original permit application dated December 11, 1995, the
facility was built to ultimately accommodate four pumps (3 duty, 1 stand-by)
for a firm pumping capacity of 18 million gallons per day (MGD). However,
only two pump units (1 duty, 1 stand-by) were initially installed to meet the
demands at that time. Since the station was built, the basin sewer flows have
increased and the station is nearing its current capacity. This project will add
the remaining two pumps to the facility to bring the firm pumping capacity to
18 MGD in order to meet the future sewer conveyanceneeds of the Six Mile
Creek basin.
