ENCOMPASS HEALTH CORPORATION HANGAR 20 Stormwater Outfall, Birmingham, Alabama

ENCOMPASS HEALTH CORPORATION HANGAR 20 is a stormwater outfall located at 4851 65th Place North in Birmingham, Jefferson County, Alabama. The facility is operational and falls under the stormwater management framework of the United States, specifically regulated under the Clean Water Act and EPA's NPDES MS4 permit program. As a stormwater outfall, it discharges runoff from an industrial catchment, likely associated with healthcare or related activities given the NAICS code 622310 (hospitals). The facility operates within the regulatory context of Phase II MS4 permits, which require stormwater management programs to reduce pollutant discharges to the maximum extent practicable. Typical controls include best management practices (BMPs) for erosion, sediment, and runoff quality. The outfall's location in Birmingham places it within the jurisdiction of local MS4 authorities that must comply with NPDES requirements. Environmental significance of this outfall relates to its potential impact on receiving waters in the Birmingham area. Stormwater runoff from industrial sites can carry pollutants such as heavy metals, oils, and pathogens. Proper management and monitoring are essential to protect local water quality and comply with the Clean Water Act's goal of restoring and maintaining the chemical, physical, and biological integrity of the nation's waters.

Birmingham, Alabama, experiences a humid subtropical climate with frequent rainfall, making stormwater management critical. The outfall discharges into local waterways that may be impaired by urban and industrial runoff. Regulatory oversight under the EPA's NPDES MS4 program requires permits to control pollutants through structural and non-structural BMPs. The facility's industrial catchment (NAICS 622310) may contribute specific contaminants requiring targeted treatment.
