ELK CORPORATION OF ALABAMA Stormwater Outfall, Tuscaloosa, Alabama

ELK CORPORATION OF ALABAMA is a stormwater outfall located at 4602 Stillman Boulevard in Tuscaloosa, Alabama, United States. The facility is operational and serves as a point of discharge for stormwater runoff from an industrial site classified under NAICS 324122 (asphalt paving mixture and block manufacturing). As a stormwater outfall, it is part of the broader municipal separate storm sewer system (MS4) network in Tuscaloosa County. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) permitting program. Stormwater discharges from industrial activities are typically regulated under NPDES Multi-Sector General Permits (MSGP) or individual permits. The outfall is subject to requirements for stormwater pollution prevention plans (SWPPP), best management practices (BMPs), and monitoring to minimize pollutant loads to receiving waters. This outfall contributes to managing stormwater runoff from an industrial facility in Tuscaloosa, a city in west-central Alabama. The local environmental context includes potential discharge to tributaries of the Black Warrior River, which is a significant waterbody in the region. Proper stormwater management is critical to protect water quality and aquatic habitats in this watershed.

The outfall is located in Tuscaloosa, Alabama, within the Black Warrior River watershed. Industrial stormwater discharges from facilities like asphalt manufacturing can introduce pollutants such as sediment, heavy metals, and hydrocarbons into local waterways. The region experiences a humid subtropical climate with frequent rainfall, increasing the importance of effective stormwater management to prevent erosion and contamination. Regulatory oversight under the NPDES program aims to mitigate these impacts through permit conditions and monitoring requirements.
