RE: Fast Track Sewer Application Raleigh Regional Office
Wastewater Treatment Plant Improvements — Sewer Interceptor
Town of Siler City, North Carolina
Dear Mr. Vinson:
Please find enclosed for your review one (1) original and one (1) copy of a Fast Track Sewer
System Extension Application package for the above referenced project. Please also find a check
in the amount of $480 to cover the application fee.
The proposed project is replacement of the Town of Siler City's existing 24" interceptor along
Loves Creek with a new 36" Interceptor. No additional flows are permitted with this project as an
existing interceptor no new connections are included. The proposed project is intended to increase
capacity and reduce Infiltration and Inflow into the sewer system. This project is part of the pending
Special Order by Consent.
If you have any questions during your review or require further information regarding this project,
please do not hesitate to give me a call at 910-295-3159.
Sincerely,
McGILL ASSOCIATES, P.A.
