Tarrant Plant Stormwater Outfall in Birmingham, Alabama

Tarrant Plant is a stormwater outfall located at 2201 Pinson Highway in Birmingham, Alabama, within Jefferson County. As a stormwater outfall, it is part of the municipal separate storm sewer system (MS4) that manages runoff from urban and industrial areas in the region. The facility is operational and plays a role in conveying stormwater to receiving waters, subject to regulatory oversight under the Clean Water Act. The facility operates under the US EPA NPDES MS4 permit framework, which requires stormwater management programs to reduce pollutant discharges. Birmingham, as a Phase I municipality, has specific permit requirements for controlling stormwater runoff. The plant's NAICS code 324121 indicates its association with petroleum refining, suggesting the outfall may serve an industrial catchment area, which can influence the characteristics of the discharged stormwater. Environmental significance of Tarrant Plant lies in its role in managing stormwater quality and quantity in an urban-industrial setting. Proper operation helps mitigate flooding, erosion, and pollution of local water bodies. The facility contributes to community resilience by reducing the impact of stormwater runoff on Birmingham's infrastructure and downstream ecosystems.

Birmingham, Alabama, experiences a humid subtropical climate with frequent thunderstorms and heavy rainfall, making stormwater management critical. The outfall likely discharges to a local water body, potentially the Black Warrior River or its tributaries, which are important for regional ecology and water supply. Urban and industrial runoff can carry pollutants such as sediment, heavy metals, and hydrocarbons, necessitating effective stormwater controls under the MS4 permit program.
