DUNN CONSTRUCTION - OPNS/MAINT. FACILITY Stormwater Outfall in Birmingham, Alabama

DUNN CONSTRUCTION - OPNS/MAINT. FACILITY is a stormwater outfall located at 2524 Birmingham Road in Birmingham, Jefferson County, Alabama. As a stormwater outfall, it discharges runoff from the Dunn Construction operations and maintenance facility into the local watershed. The facility operates under the United States regulatory framework, specifically the EPA NPDES MS4 program, which governs stormwater discharges from industrial and municipal sources. The facility's primary function is to manage stormwater runoff from an industrial construction site, which may include sediment, debris, and other pollutants. Typical stormwater management at such facilities involves best management practices (BMPs) such as detention basins, sediment traps, and erosion controls to comply with Clean Water Act requirements. In Alabama, stormwater permits are administered by the Alabama Department of Environmental Management (ADEM), which enforces effluent limits and monitoring requirements. This outfall contributes to the overall stormwater management infrastructure in Birmingham, a city with a significant industrial base. Proper operation helps prevent flooding and protects receiving water bodies from pollution. The facility's location in an urban-industrial area means its discharge may affect local streams and rivers, highlighting the importance of compliance with permit conditions to minimize environmental impact.
