Foster Farms Demopolis Plant Stormwater Outfall | Demopolis, Alabama

Foster Farms Demopolis Plant is a stormwater outfall located at 232 North Industrial Park Drive in Demopolis, Marengo County, Alabama. This facility manages stormwater runoff from an industrial poultry processing site, classified under NAICS codes 311412, 311615, and 311919. As a stormwater outfall, it plays a key role in conveying treated or untreated stormwater to receiving waters, subject to federal and state regulations. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) permitting framework, which governs stormwater discharges from industrial activities. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program, including Multi-Sector General Permits for industrial stormwater. The plant's stormwater management likely includes best management practices (BMPs) such as detention basins, oil-water separators, or vegetated swales to control pollutants. Environmental significance centers on the potential discharge to nearby water bodies, such as the Tombigbee River, which flows through Demopolis. Industrial stormwater can carry pollutants like sediment, nutrients, and chemicals, making compliance with permit limits critical for protecting aquatic ecosystems. The facility's location in an industrial park underscores the importance of stormwater controls in urbanized catchments.

Demopolis, Alabama, lies along the Tombigbee River in the Gulf Coastal Plain, a region with high rainfall and clay soils that can generate significant stormwater runoff. Industrial facilities like poultry processing plants contribute pollutants such as organic matter, phosphorus, and pathogens to stormwater, which can impair water quality in receiving streams. The area's ecology supports diverse aquatic life, including fish and mussels, making effective stormwater management essential to prevent eutrophication and habitat degradation.
