Vulcan Materials Aviation Department Stormwater Outfall, Birmingham, Alabama

Vulcan Materials Aviation Department at Birmingham International Airport is a stormwater outfall located at 4110 65th Street North in Birmingham, Jefferson County, Alabama. This facility manages stormwater runoff from the airport and associated industrial activities, operating under the U.S. EPA's NPDES MS4 permit framework. As part of a major transportation hub, the outfall handles runoff from impervious surfaces including runways, tarmacs, and industrial areas. The facility operates under Alabama's NPDES stormwater program, which implements the Clean Water Act requirements for municipal separate storm sewer systems (MS4s). Given its location at an international airport, the outfall likely manages stormwater from deicing operations, fuel storage areas, and vehicle maintenance zones, requiring treatment for pollutants such as heavy metals, hydrocarbons, and suspended solids. The NAICS code 481219 (Other Nonscheduled Air Transportation) indicates the primary activity is aviation support. Environmental significance includes potential discharge to local waterways in the Black Warrior River watershed. Stormwater from airport facilities can carry pollutants that impact aquatic ecosystems. Proper management through best management practices (BMPs) such as detention basins, oil-water separators, and regular monitoring is essential to protect water quality in Jefferson County and downstream communities.

Birmingham, Alabama, experiences a humid subtropical climate with frequent thunderstorms, leading to high stormwater runoff volumes. The airport's location in an urbanized area means runoff may carry pollutants from aviation activities, including deicing fluids, fuel residues, and heavy metals. Discharge to local streams in the Black Warrior River basin requires compliance with EPA water quality standards to prevent impairment of aquatic habitats.
