HUNTSVILLE DC Stormwater Outfall, Madison, Alabama | United States

HUNTSVILLE DC is a stormwater outfall located at 114 Jetplex Circle in Madison, Alabama, within Madison County. It is part of the stormwater management infrastructure for the Huntsville metropolitan area, a region experiencing rapid urban growth. The facility operates under the US EPA NPDES MS4 permit framework, which regulates stormwater discharges from municipal separate storm sewer systems to protect water quality. As a stormwater outfall, this facility collects and discharges urban runoff from impervious surfaces such as roads, parking lots, and rooftops. The NAICS code 484121 indicates a focus on general freight trucking, suggesting the outfall may serve an industrial or commercial catchment area. The facility's operational status ensures ongoing management of stormwater volumes and pollutant loads, which is critical for compliance with Clean Water Act requirements. Environmental significance lies in its role in mitigating flooding and reducing pollutant loads to receiving waters. The outfall likely discharges to a local waterbody, such as the Tennessee River system, which supports aquatic habitats and regional water supply. Effective stormwater management helps prevent erosion, sedimentation, and contamination from urban runoff, contributing to the ecological health of the surrounding area.

Madison, Alabama, is part of the Tennessee Valley region, characterized by a humid subtropical climate with frequent thunderstorms and occasional hurricanes, leading to high stormwater runoff volumes. Urban development in the Huntsville metropolitan area increases impervious surfaces, elevating runoff and pollutant loads. The facility likely discharges to a tributary of the Tennessee River, which is a major water resource for the region. Regulatory oversight under the EPA NPDES MS4 program requires controls to minimize impacts on water quality, including sediment, nutrients, and heavy metals from urban and industrial sources.
