Water Quality 512 North Permitting h Salisbury Street, itCS nit t, Sue 9256,VL 3 2019 ,1Q Raleigh, North Carolina 27604 "V Re: Whiteville - Phase 1 Mollies Branch Sewer Improve iVennt NCDEQ-DWI Project #E-SRP-W-17-0123 ES Project # 18006 Please find the enclosed sewer system extension application package for the above referenced project for your review. The City of Whiteville is proposing to make improvements to their sanitary sewer system by replacing a section of one of their sewer outfall lines. This portion of their existing sewer system is old, has exceeded is useful life -expectancy, and is deficient, which increases the likelihood of sewer back-ups, overflows, and spills during heavy rain events and exfiltration of sewage during dry periods. Enclosed for your review are the following: • One (1) original and one (1) copy of this cover letter. • A check for $480.00 for the application review fee. • One (1) original and one (1) copy of the Sewer System Extension Form (SSEA 04-16) with Attachment "A" for High Priority Sewers. • One (1) original and one (1) copy of the Flow Tracking/Acceptance Form (FTSE 04-16). • Two sets of plan drawings. • One (1) original and one (1) copy of a site map using an 8.5" x 11" color copy of a USGS Topographic Map to show the project location. There are street level maps showing the project area on the Title Page and the Index Page of the plan drawings. • One (1) original and one (1) copy of the Technical Specifications. This project is funded through a loan from NCDEQ's State Reserve Program. The City is proposing to replace these existing sewer mains, manholes, and services with like -size pipe and manholes, in the same basic horizontal location; although in a few areas the sewer main is being moved a short distance horizontally to get the main out from under buildings or away from drainage ditches. The project will not include any additional connections or flow and is primarily for the purpose of maintenance. The existing sewer mains are 8", 12" and 15" VCP and will be replaced with 8", 12", and 16" PVC and DIP, and 14" HDPE (Pipe Bursting, 12" I.D.) mains.
