JET-PEP #430 (CROWN TARRANT) Stormwater Outfall, Birmingham, Alabama

JET-PEP #430 (CROWN TARRANT) is a stormwater outfall located at 4318 Vanderbilt Road in Birmingham, Jefferson County, Alabama. As a stormwater outfall, it discharges collected stormwater runoff from the surrounding urban catchment into local waterways. The facility is operational and falls under the regulatory purview of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program, which governs stormwater discharges in urbanized areas. In Alabama, stormwater management is primarily regulated by the Alabama Department of Environmental Management (ADEM) under delegated authority from the EPA. The facility likely serves an industrial or commercial area, given its location in an urban setting. Stormwater outfalls like this one are critical for controlling runoff volume and quality, preventing flooding, and reducing pollutant loads to receiving waters. The environmental significance of this outfall lies in its role in managing stormwater runoff from the Birmingham area. Urban runoff can carry pollutants such as sediment, heavy metals, and nutrients, which can impair water quality in downstream water bodies. Proper operation and maintenance of this outfall are essential for compliance with water quality standards and for protecting the ecological health of local streams and rivers.

Birmingham, Alabama, experiences a humid subtropical climate with frequent thunderstorms and heavy rainfall, making stormwater management crucial. The outfall discharges into the Black Warrior River watershed, which supports diverse aquatic life and provides drinking water. Urban runoff from industrial and residential areas can introduce pollutants, necessitating effective stormwater controls under the NPDES MS4 program to protect water quality.
