MITSUBISHI POLYCRYSTALLINE SILICON OF AMERICA CORPORATION Stormwater Outfall, Theodore, Alabama

MITSUBISHI POLYCRYSTALLINE SILICON OF AMERICA CORPORATION operates a stormwater outfall in Theodore, Mobile County, Alabama, United States. This facility manages stormwater runoff from an industrial site involved in semiconductor and related manufacturing (NAICS 331410, 331419, 334413). The outfall is part of the company's environmental compliance infrastructure for its operations in the region. As a stormwater outfall in the United States, this facility is subject to the Clean Water Act and EPA's NPDES permitting program. Industrial stormwater discharges are typically regulated under Multi-Sector General Permits or individual permits, requiring implementation of stormwater pollution prevention plans (SWPPPs) and best management practices (BMPs) to control pollutants. The facility's location in an industrial area of Theodore suggests runoff may contain metals, chemicals, or other process-related constituents. The outfall discharges to local water bodies in the Mobile Bay watershed, which is ecologically significant for its estuarine habitats and biodiversity. Proper stormwater management at this facility helps protect downstream water quality and supports compliance with Alabama's water quality standards. The facility's operational status indicates ongoing monitoring and maintenance of stormwater controls.

The stormwater outfall discharges into the Mobile Bay watershed, a large estuarine system supporting diverse aquatic life and commercial fisheries. Industrial runoff from semiconductor and metals manufacturing can contain pollutants such as heavy metals, acids, and suspended solids. The facility's stormwater management program is critical to minimizing impacts on sensitive downstream habitats, including wetlands and coastal areas. Regulatory oversight under the Clean Water Act ensures that discharge limits and best management practices are maintained to protect water quality.
