Briar Creek Relief Sewer - Phase II
Pre-Construction Notification for Nationwide 12/GC 3819
Dear Mr. McMillan,
Charlotte-Mecklenburg Utilities proposes to construct a new sewer along Briar Creek in
Mecklenburg County. The Briar Creek Relief Sewer is needed to increase capacity in the sewer
system to minimize system surcharging and overflows. The overall project is being designed
and constructed in three separate phases, and this application addresses only Phase Il. Phase II
of the Briar Creek Relief Sewer project involves the installation of approximately 4,235 feet of
54-inch, 3,265 feet of 48-inch, and 9,000 of 42-inch sewer. The project will begin just west of
Country Club Drive and follow Briar Creek downstream to south of Randolph Road. Briar
Creek will be temporarily impacted by installation of the sewer pipe across Briar Creek and its
tributaries at 11 locations. In addition, four existing aerial sewers crossing Briar Creek or its
tributaries will be removed. No wetlands will be impacted by this project.
Enclosed please find the following items:
1. a check in the amount of $570 for the application fee;
2. five copies of the Pre-Construction Notification Application with attachments (including
A. continued stream impacts table, B. latitudes and longitudes of stream crossings, C.
stream crossing GIS map, D. USGS map, E. photocopy of SEPA approval
documentation, and F. Wetland Determination Data Form).
3. two copies of full size plans;
4. three copies of 11x17 plans.
If you have any questions, please contact me at [phone].

This project will not expand the existing wastewater treatment service area. the project addresses wet-weather capacity
inadequacies in the system. The increased capacity as a result of this project will allow the build-out population of the
Briar Creek sewer shed to be served by the sewer syetem. The service area is expected to increase in population by
approximately 14 percent by 2030, the year the service area is expected to reach the build-out level. An Environmental
Assessment was prepared and FONSI approved for the project (See attached copies of letters).
4. Sewage Disposal (DWQ Requirement)
4a. Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from
the proposed project, or available capacity of the subject facility.
Wastewater flow generated from the proposed project will be conveyed by this relief sewer and the existing collection
system to CMU's existing Sugar Creek WWTP, where it will be treated and discharged.

Dear Ms. Bo=:
Tne Division of Water Quality (DWQ) has reviewed your 24 October 2005 cmTM5po^3Pn1e (?taclled 'or

An Envimnr ,tai Assessment (EA) was xepa.red for hz project m Aug st 2000; an,
