IMPORT AUTO SALES Stormwater Outfall, Madison, Alabama

IMPORT AUTO SALES is a stormwater outfall located at 30585 Highway 72 in Madison, Limestone County, Alabama, United States. This facility is part of the stormwater management infrastructure serving an industrial catchment area, likely associated with auto sales or related commercial activities. As a stormwater outfall, it discharges collected runoff into local waterways, operating under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. The facility is operational and falls under the jurisdiction of Alabama's stormwater regulations, which implement the Clean Water Act requirements. Stormwater outfalls in industrial catchments typically handle runoff from impervious surfaces such as parking lots, rooftops, and loading areas. The outfall likely includes basic treatment measures such as sediment basins or oil-water separators to manage pollutants common in automotive settings, including heavy metals, hydrocarbons, and suspended solids. As part of the Tennessee River watershed, the outfall discharges into receiving waters that may be sensitive to urban runoff. The facility's location in a growing suburban area near Huntsville underscores the importance of stormwater management in preventing flooding and protecting water quality. Compliance with MS4 permit requirements, including monitoring and best management practices, is essential for minimizing environmental impact.

The outfall discharges into the Tennessee River basin, which supports diverse aquatic life and provides drinking water for downstream communities. Urban and industrial runoff from the Madison area can introduce pollutants such as sediment, oil, grease, and heavy metals. Effective stormwater management is critical to prevent impairment of local water bodies and to comply with Clean Water Act goals.
