Mercury Air Center Stormwater Outfall, Birmingham, Alabama

Mercury Air Center is a stormwater outfall located at 4725 65th Place North in Birmingham, Jefferson County, Alabama. It operates within the United States' regulatory framework for stormwater management, specifically under the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. As an industrial facility classified under NAICS 488999 (Other Support Activities for Air Transportation), its stormwater discharges are subject to oversight to prevent pollution of local waterways. The facility's stormwater management involves controlling runoff from impervious surfaces and industrial operations. In Alabama, stormwater permits are administered by the Alabama Department of Environmental Management (ADEM), which enforces compliance with the Clean Water Act. Typical best management practices (BMPs) include sediment basins, oil-water separators, and regular monitoring to ensure discharge quality meets state and federal standards. As part of Birmingham's urban infrastructure, Mercury Air Center contributes to the city's stormwater network, which drains into the Black Warrior River watershed. Proper management of stormwater outfalls is critical to reducing flooding risks and protecting water quality in receiving water bodies. The facility's operational status indicates ongoing compliance with regulatory requirements to mitigate environmental impacts from stormwater runoff.

Birmingham's stormwater runoff flows into the Black Warrior River watershed, which supports diverse aquatic habitats and provides drinking water for the region. Urban and industrial catchments like Mercury Air Center can introduce pollutants such as sediment, heavy metals, and hydrocarbons into waterways. The facility's location in an industrial area necessitates robust stormwater controls to prevent degradation of local water quality and to comply with Total Maximum Daily Load (TMDL) requirements for impaired water bodies.
