Harbert Aviation, LLC Stormwater Outfall, Birmingham, Alabama | USA

Harbert Aviation, LLC is a stormwater outfall facility located at 4904 69th Street North in Birmingham, Jefferson County, Alabama, United States. The facility is operational and serves as a point of discharge for stormwater runoff from an aviation-related industrial site, classified under NAICS code 488119 (Other Airport Operations). As a stormwater outfall, it is part of the broader network of municipal separate storm sewer systems (MS4) regulated under the Clean Water Act. The facility operates within the regulatory framework of the US EPA's NPDES MS4 permit program, which governs stormwater discharges from industrial and municipal sources. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program. The outfall likely handles stormwater from impervious surfaces such as runways, tarmacs, and parking areas, with typical management practices including detention basins, oil-water separators, or filtration systems to control pollutants. The environmental significance of this outfall lies in its potential impact on local water bodies in the Birmingham area. Stormwater runoff from industrial sites can carry pollutants like heavy metals, hydrocarbons, and sediment. Proper management is critical to protect receiving waters, which may include tributaries of the Black Warrior River system. The facility's compliance with its NPDES permit ensures that discharges meet water quality standards, supporting the ecological health of the region.

Birmingham, Alabama, experiences a humid subtropical climate with frequent thunderstorms, leading to significant stormwater runoff. The area's industrial history, including aviation and manufacturing, contributes to potential pollutant loads in runoff. The facility's discharge likely enters local waterways that are part of the Black Warrior River basin, which supports diverse aquatic life and is used for recreation and water supply. Effective stormwater management is essential to prevent erosion, flooding, and contamination of these sensitive water bodies.
