Wetumpka Municipal Airport Stormwater Outfall, Elmore, Alabama | US Stormwater Facility

Wetumpka Municipal Airport Stormwater Outfall is located in Elmore, Alabama, United States, and manages stormwater runoff from the airport facility. As a stormwater outfall, it collects and discharges stormwater from the airport's impervious surfaces, including runways, taxiways, and parking areas. The facility is operational and falls under the jurisdiction of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. Stormwater outfalls at airports are typically regulated under Phase II MS4 permits for small municipalities or industrial stormwater permits. The outfall likely includes best management practices (BMPs) such as detention basins, oil-water separators, or vegetated swales to treat runoff before discharge. The facility's NAICS code 488119 (Other Airport Operations) indicates its role in supporting airport activities. The environmental significance of this outfall lies in its potential to affect local water quality. Stormwater runoff from airports can contain pollutants like de-icing fluids, fuel residues, and sediment. Proper management is essential to protect nearby water bodies, such as the Coosa River or its tributaries, from contamination. The facility's compliance with NPDES permits ensures monitoring and treatment of discharges to minimize environmental impact.

The Wetumpka Municipal Airport Stormwater Outfall discharges into the Coosa River watershed, a region with diverse aquatic ecosystems. Stormwater runoff from airport operations may carry pollutants such as hydrocarbons, heavy metals, and sediment, which can impair water quality. The outfall is subject to NPDES MS4 permit requirements, including implementation of stormwater control measures and regular monitoring to protect receiving waters.
