CARMAX #7224 is a stormwater outfall located at 2796 John Hawkins Parkway in Hoover, Jefferson County, Alabama. This facility manages stormwater runoff from a used car dealership (NAICS 441120), operating under the regulatory framework of the US EPA's NPDES MS4 program, which governs discharges from municipal separate storm sewer systems. As a Phase II small MS4, Hoover's stormwater management is subject to local permit requirements aimed at reducing pollutant loads to receiving waters. Typical stormwater outfalls in this sector manage runoff from impervious surfaces such as parking lots and building roofs. The outfall likely includes basic treatment measures like sediment basins or oil-water separators to comply with state and federal water quality standards. Located in the Cahaba River watershed, this outfall discharges to a waterbody that supports diverse aquatic life and serves as a drinking water source. Proper stormwater management is critical to prevent erosion, flooding, and contamination from automotive pollutants like oil, grease, and heavy metals. The facility's role is part of a broader network of controls required under the Clean Water Act to protect downstream ecosystems.
Environmental context
The outfall discharges into the Cahaba River basin, a biologically diverse watershed that provides habitat for several rare species and serves as a water supply for Birmingham. Urban runoff from commercial areas like this dealership can carry pollutants such as hydrocarbons, heavy metals, and sediment. Regulatory oversight under the EPA's NPDES MS4 program requires implementation of best management practices to minimize these impacts and protect water quality.
