Stephens Pipe and Steel LLC Stormwater Outfall, Warrior, Alabama | Industrial Stormwater Management

Stephens Pipe and Steel LLC is a stormwater outfall located at 2891 State Hwy 160 in Warrior, Blount County, Alabama, United States. The facility is operational and classified under NAICS code 331222 (Steel Wire Drawing). As an industrial stormwater outfall, it manages runoff from steel manufacturing operations, which is a sector with potential for pollutant loading including metals and suspended solids. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) permitting framework. Industrial stormwater discharges are typically regulated under Multi-Sector General Permits (MSGP) or individual permits, requiring implementation of stormwater pollution prevention plans (SWPPPs) and best management practices (BMPs) to control runoff. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program. Environmental significance of this outfall relates to its discharge into local waterways in the Black Warrior River watershed. Industrial stormwater can carry pollutants that may impact water quality and aquatic habitats. Proper management through BMPs such as sediment basins, oil-water separators, and regular monitoring is essential to minimize environmental impact and maintain compliance with Clean Water Act requirements.

The facility is located in the Black Warrior River watershed in Alabama, a region with a humid subtropical climate characterized by frequent rainfall events that generate stormwater runoff. Industrial stormwater discharges from steel manufacturing can contain pollutants such as heavy metals, oils, and total suspended solids, which may affect receiving water quality. The local environmental context includes potential impacts on aquatic ecosystems and downstream water uses, necessitating effective stormwater management under the Clean Water Act.
