SWONCOTT ASPHALT Stormwater Outfall, Madison, Alabama | United States

SWONCOTT ASPHALT is a stormwater outfall facility located at 860 Swancott Road in Madison, Alabama, United States. The facility is operational and serves the Madison area, managing stormwater runoff from an industrial catchment associated with asphalt manufacturing (NAICS 324121). As a stormwater outfall, it discharges treated stormwater into local waterways, subject to regulatory oversight. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. Madison, Alabama, is part of the Phase II MS4 area, requiring stormwater management plans to reduce pollutant discharges to the maximum extent practicable. The facility's industrial classification suggests potential exposure to pollutants typical of asphalt production, such as hydrocarbons and suspended solids, which are regulated under the Clean Water Act. Stormwater outfalls like SWONCOTT ASPHALT play a critical role in preventing flooding and protecting water quality in urban and industrial areas. The facility contributes to local stormwater infrastructure, helping to manage runoff from impervious surfaces and industrial operations. Its location in Madison, a growing city in northern Alabama, underscores the importance of effective stormwater management in supporting community development and environmental protection.

The facility discharges stormwater into local water bodies in the Tennessee River basin, which may be sensitive to pollutants from industrial runoff. Madison's climate features frequent rainfall, increasing the volume of stormwater runoff and the potential for pollutant transport. The industrial catchment, including asphalt manufacturing, introduces risks of hydrocarbon and sediment contamination, requiring effective best management practices to protect aquatic ecosystems.
