Sullins Governor Director March 15, 2011 Robert L. 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: Resources 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 (NC0021474) from January 2009 through December 2009 was evaluated to determine the peak 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 NPDES permit for the treatment facility or exceed the capacity of the sewers downstream of any new sewer extension or service connection(s). 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].
