Wilson City Manager City of Mebane 106 East Washington Street Mebane, NC 27302 Subject: Mebane WWTP (NC0021474) Flow Reduction Request Alamance County Dear Mr. Wilson: Dee Freeman Secretary On February 14, 2011, the Pretreatment, Emergency Response and Collection System (PERCS) Unit of the Division of Water Quality received a flow reduction request for connections to the City of Mebane WWTP. The letter requests an allowable flow rate of 80 gallons per day (gpd) per bedroom based on the evaluated data. As daily WWTP data is not representative of the project area, the DMR data from the City of Mebane WWTP (NC002I474) from January 2009 through December 2009 was evaluated to determine the peals sewage month. The highest flow month was December 2009. Daily wastewater flows were recorded downstream of the Holly Ridge Subdivision during December 2010. This data was reviewed by PERCS and Regional Office staff. Based on the data, the Division hereby grants a reduction in flow to 80 gpd/bedroom (minimum of 160 gpd for 1 and 2 bedroom residences) for sewer extension permits issued tributary to the City of Mebane WWTP. Regardless of the adjusted design daily wastewater flow rate, at no time shall the wastewater flows exceed the effluent limits defined in the NPDESRermit for the treatment facility or exceed the capacity of the sewers downstream of any new sewer extension or service connections . If you have any questions or comments regarding this matter, please contact Sarah Morrison at (919) 807-6310, or email [Sarah.Morrison@ncdenr.gov] or Deborah Gore, Unit Supervisor at (919) 807-6383, or email [Deborah.Gore@ncdenr.gov].

Project Narrative: The Bowman Place project consists of a new 128 lot subdivision which is part of a larger 177 lot subdivision with associated public roadways, utilities, open space, drives, parking, etc. being built on two parcels of land totaling 68.64 acres. The phases included for Bowman Village have been permi tedtugUbr a separate cover. The homes will be a mix of three- and four -bedroom models. The site is la4ated in the vicinity of 7117 Bowman Road, Mebane North Carolina with this portiog-of the site being south of Bowman road. It can be identified with PIN# 9824-74-5328 & -9924-73-6163. The development of this subdivision will require a public sewer extension to tie into the City of Mebane sewer system. This portion of the gravity sewer extension will consist of 22 new manholes, 2,,042 If of 8" ductile iron pipe (DIP) and 2,378 If of 8" PVC pipe. The new sewertmain will tie into a City of Mebane 8" ductile iron sewer main at a newly constructed manholr, which is part of the Bowman Village sewer permit submittal.
