B&S Used Auto Parts, Inc. Stormwater Outfall, Selma, Alabama

B&S Used Auto Parts, Inc. is a stormwater outfall located at 904 Kings Bend Road in Selma, Dallas County, Alabama, United States. The facility is operational and manages stormwater runoff from an industrial site classified under NAICS 423140 (Motor Vehicle Parts, Used). As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state regulations. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit framework. As a Phase II small MS4, it must implement a stormwater management program to reduce pollutant discharges to the maximum extent practicable. The industrial catchment area, involving auto parts recycling, may contribute pollutants such as oil, grease, heavy metals, and sediment, requiring best management practices (BMPs) for treatment. Environmental significance lies in its discharge to the Alabama River watershed, which supports aquatic habitats and downstream communities. Proper stormwater management at this facility helps protect water quality in Selma and the broader region. Compliance with NPDES permit conditions is critical to minimize impacts on impaired water bodies and maintain ecological integrity.

The facility discharges stormwater into the Alabama River basin, which is subject to Total Maximum Daily Load (TMDL) requirements for pollutants like sediment and nutrients. The industrial nature of the site increases the risk of runoff containing hydrocarbons and metals, necessitating robust stormwater controls. Local climate with seasonal heavy rainfall can exacerbate runoff volumes and pollutant loading.
