OMNISOURCE SOUTHWEST LLC- BIRMINGHAM Stormwater Outfall, Birmingham, Alabama

OMNISOURCE SOUTHWEST LLC- BIRMINGHAM is a stormwater outfall facility located at 3700 14th Ave N, Birmingham, Alabama, in Jefferson County. The facility is operational and serves as a point of discharge for stormwater runoff from an industrial catchment area. As a stormwater outfall, it is subject to the US Clean Water Act and NPDES MS4 permit requirements, which regulate stormwater discharges to protect water quality. Stormwater outfalls like this one are critical components of urban drainage systems, conveying runoff from impervious surfaces such as parking lots, roofs, and industrial yards. In Alabama, stormwater management is governed by state and federal regulations, including the EPA's Phase II MS4 program for small municipalities and industrial facilities. The facility's location in an industrial area suggests potential exposure to pollutants typical of such settings, including heavy metals, oils, and sediments. The environmental significance of this outfall lies in its potential impact on receiving waters. Discharges from industrial catchments can carry pollutants that may impair water quality if not properly managed. The facility's compliance with its NPDES permit is essential to minimize adverse effects on local waterways. Stormwater outfalls in urban and industrial areas are increasingly managed through best management practices (BMPs) such as detention basins, filtration systems, and regular monitoring to reduce pollutant loads.

Birmingham, Alabama, has a humid subtropical climate with frequent thunderstorms, leading to significant stormwater runoff. The city's industrial history, including steel and manufacturing, contributes to potential pollutant loads in stormwater discharges. The outfall is located in an industrial area near the Village Creek watershed, which drains to the Black Warrior River. Managing stormwater quality is critical to protect these water bodies from sedimentation, heavy metals, and other contaminants associated with industrial activities.
