The site is bordered by Chappell Loop Rd. to the south, and residential properties to the north, east and west. The project proposes the construction of five apartment buildings containing 60 one-bedroom and 14O two-bedroom apartments. The requested flow will be for 28,000 GPD (14O gpd/unit). This flow will be routed to an Existing Public SSMH by means of 8" gravity mains with 6" PVC services proposed for this site. The flow will ultimately reach the Belville WWTP treatment plant, Permit No. NCo07554O. Stormwater runoff from this site is discharged to Brunswick River in the Cape Fear River Basin, Classification SC, Index# 18-77.

November 5,2010 Coast Line Engineering PLLC 2107 Laurel Oak Way Leland,NC 28451 Subject: Belville WWTP (NC0075540) Flow Reduction Request Brunswick County- Dear Mr.Fennell: On May 17, 2010, the Pretreatment, Emergency Response and Collection Systems (PERCS)Unit of the Division of Water Quality received a flow reduction request for connections to the Belville WWTP. The letter requests an allowable flow rate of 70 GPD per bedroom based on the evaluated data from the WWTP and water usage data. Additional information requested regarding Belville WWTP DMR flow values, diverted wastewater flows and flow calibration was received on October 7,2010. The DMR data from the Belville WWTP (NC0075540) from January 2009 through July 2010 was analyzed by PERCS Unit staff, along with water usage data from H2GO, as well as inflow and infiltration data. The highest usage month was February 2010 for the Belville WWTP. Based on the data, the Division hereby grants a reduction in flow,to 70 gpd/bedroom (minimum of 140 gpd for 1 and 2 bedroom residences) for sewer extension permits issued tributary to the Belville WWTP. Regardless of the adjusted design daily wastewater flow rate at no tune 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 connections) If you have any questions or comments regarding this matter, please contact Sarah Morrison at (919) 807-6310, email [Sarah.Morrison@icdenr.gov] or Deborah Gore, Unit Supervisor at (919) 807-6383, email [Deborah.Gore@ncdenr.gov].
