This facility manages stormwater runoff from a commercial retail site, classified under NAICS 811192 (Car Washes). As a stormwater outfall, it discharges collected runoff into local waterways, operating under the regulatory framework of the US EPA's National Pollutant Discharge Elimination System (NPDES) and the Clean Water Act. In Alabama, stormwater outfalls from commercial facilities are typically regulated under NPDES MS4 permits, which require controls to reduce pollutant discharges. The facility's location in Mobile County places it within a region subject to Phase II MS4 requirements, given the county's urbanized area designation. Stormwater management at such sites often involves best management practices (BMPs) like detention basins, oil-water separators, or filtration systems to treat runoff before discharge. The environmental significance of this outfall lies in its potential impact on local water bodies. Grand Bay is near the Gulf Coast, where stormwater runoff can affect sensitive estuarine ecosystems. Proper management of runoff from commercial sites helps protect water quality in receiving streams and ultimately Mobile Bay. The facility's operational status indicates ongoing compliance with local stormwater regulations.
