SMI STEEL LLC Stormwater Outfall, Birmingham, Alabama | Industrial Stormwater Management

SMI STEEL LLC operates a stormwater outfall located at 101 50th St S in Birmingham, Jefferson County, Alabama. This facility manages stormwater runoff from an industrial steel manufacturing site, classified under NAICS 331110 (Iron and Steel Mills). As a stormwater outfall, it is part of the broader network of regulated discharges under the Clean Water Act, specifically subject to EPA NPDES MS4 permits for industrial stormwater. The facility operates within Alabama's regulatory framework, which follows the EPA's Phase II MS4 program for small municipalities and industrial facilities. Stormwater outfalls like this one are designed to control the volume and quality of runoff from impervious surfaces, reducing pollutants such as sediment, heavy metals, and oils that can impact receiving waters. The outfall's location in an industrial area of Birmingham suggests it handles runoff from manufacturing activities, requiring compliance with stormwater pollution prevention plans (SWPPPs). This outfall plays a key role in managing stormwater in the Birmingham urban area, helping to mitigate flooding and protect water quality in local streams and rivers. The facility's operational status indicates ongoing management of stormwater discharges, contributing to the region's environmental compliance and community resilience against stormwater-related issues.

Birmingham, Alabama, experiences a humid subtropical climate with frequent thunderstorms and occasional hurricanes, leading to significant stormwater runoff. The city's industrial history, including steel manufacturing, contributes to potential pollutants in runoff such as heavy metals and suspended solids. The outfall discharges into the Black Warrior River watershed, which is subject to TMDL requirements for sediment and other pollutants. Effective stormwater management is critical to protect aquatic habitats and downstream water quality in this region.
