Automatic Screw Machine Products Stormwater Outfall, Decatur, Alabama

Automatic Screw Machine Products is a stormwater outfall located at 709 Second Ave SE in Decatur, Alabama. This facility manages stormwater discharge from an industrial site classified under NAICS codes 332721 and 332722, which cover precision turned product manufacturing. 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 under the 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. Industrial stormwater outfalls like this one are subject to monitoring and best management practices to control pollutants such as metals, oils, and sediments. Located in Decatur, a city on the Tennessee River in northern Alabama, this outfall contributes to local stormwater management in an area with a mix of industrial and urban land uses. Proper operation helps protect downstream water quality in the Tennessee River watershed, which supports regional water supply and aquatic habitats.

The outfall discharges into the Tennessee River basin, a major waterway in the southeastern United States. The surrounding area in Decatur includes industrial zones and urban development, which can contribute pollutants such as heavy metals, hydrocarbons, and sediment to stormwater runoff. Regulatory oversight under the Clean Water Act and ADEM permits aims to minimize these impacts through pollution prevention and treatment measures.
