NEMAK USA INC Stormwater Outfall, Sylacauga, Alabama | United States

NEMAK USA INC is a stormwater outfall facility located at 2100 Old Sylacauga Highway in Sylacauga, Talladega County, Alabama, United States. The facility is operational and serves as a point of discharge for stormwater runoff from industrial activities, specifically aluminum die-casting operations classified under NAICS codes 331521-331524. As an industrial stormwater outfall, this facility operates under the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework, which requires compliance with effluent limitations and best management practices to control pollutants in stormwater runoff. The facility is subject to Phase II MS4 requirements if located in a regulated small municipal separate storm sewer system area, or may have an individual or general industrial stormwater permit. The environmental significance of this outfall lies in its role in managing stormwater from an industrial catchment, which can carry pollutants such as heavy metals, oils, and sediments. Proper operation and maintenance of stormwater controls are critical to protect receiving waters in the Talladega County region, which may include streams and rivers that support local ecosystems and downstream water quality.

The facility discharges stormwater from an industrial catchment in Sylacauga, Alabama, an area with a humid subtropical climate that experiences significant rainfall, increasing the potential for runoff-related pollution. The outfall may discharge to local water bodies that are part of the Coosa River basin, which is ecologically important for aquatic life and downstream water supplies. Industrial stormwater discharges are regulated under the Clean Water Act to prevent contamination from heavy metals, oils, and other pollutants typical of aluminum die-casting operations.
