Overview
LOCKHEED MARTIN CORPORATION operates a stormwater outfall in Huntsville, Alabama, managing runoff from industrial facilities under US EPA NPDES MS4 regulations.
LOCKHEED MARTIN CORPORATION operates a stormwater outfall located at 4000 South Memorial Parkway in Huntsville, Alabama. This facility manages stormwater runoff from industrial operations, including paint and coating manufacturing (NAICS 325510) and miscellaneous manufacturing (NAICS 339999). As a Phase II small MS4 under the Clean Water Act, the outfall is subject to NPDES permit requirements for stormwater discharge. The facility operates under the regulatory framework of the US EPA's National Pollutant Discharge Elimination System (NPDES), which governs stormwater discharges from industrial activities. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program. The outfall likely includes best management practices (BMPs) such as detention basins, oil-water separators, or filtration systems to treat runoff before discharge. This stormwater outfall serves a critical role in managing runoff from a large industrial complex in Huntsville, a city with significant aerospace and manufacturing sectors. Proper stormwater management helps protect local water bodies, including the Tennessee River watershed, from pollutants such as heavy metals, oils, and sediments. The facility's compliance with NPDES permits ensures that industrial runoff meets water quality standards, supporting both environmental protection and community water resources.
Environmental context
The facility is located in Huntsville, Alabama, within the Tennessee River watershed. The region experiences a humid subtropical climate with frequent rainfall, making stormwater management critical to prevent flooding and water pollution. Industrial runoff from manufacturing operations can contain pollutants like heavy metals, hydrocarbons, and suspended solids. The outfall discharges to local waterways that may be impaired, requiring stringent permit conditions under the Clean Water Act to protect aquatic ecosystems and downstream water quality.
