City of Birmingham Department of Public Stormwater Outfall, Birmingham, Alabama

The City of Birmingham Department of Public stormwater outfall is located at 501 6th Avenue South in Birmingham, Alabama, within Jefferson County. As a stormwater outfall, it discharges collected stormwater runoff from urban and industrial areas into local waterways, operating under the regulatory framework of the US Clean Water Act and EPA NPDES MS4 permits. Birmingham, as a Phase I large municipality, is required to implement a comprehensive stormwater management program to reduce pollutant discharges. The facility's NAICS codes (325320 and 926130) indicate connections to pesticide manufacturing and environmental program administration, suggesting the outfall may serve industrial catchments. Stormwater outfalls in urban settings like Birmingham typically manage runoff from impervious surfaces, roads, and industrial sites, with treatment often limited to basic controls like detention basins or green infrastructure. The facility's operational status confirms active management of stormwater flows. This outfall is part of Birmingham's broader stormwater infrastructure, which is critical for preventing flooding and protecting water quality in receiving waters such as the Black Warrior River and Cahaba River. Effective stormwater management reduces pollutant loads, mitigates erosion, and supports compliance with Total Maximum Daily Load (TMDL) requirements for impaired water bodies in the region.

Birmingham's stormwater outfalls discharge into urban waterways that may be impaired by sediment, heavy metals, and nutrients from industrial and residential runoff. The city's combined sewer system and aging infrastructure pose additional challenges for water quality. Regulatory compliance under the NPDES MS4 permit requires monitoring and implementation of best management practices (BMPs) to reduce pollutant loads and protect downstream ecosystems.
