AMEREX CORPORATION Stormwater Outfall, Trussville, Alabama | US Stormwater Facility

AMEREX CORPORATION is a stormwater outfall facility located at 7595 GADSDEN HWY in Trussville, Jefferson County, Alabama. The facility is operational and serves as a point of discharge for stormwater runoff from the surrounding industrial and commercial catchment, which includes activities under NAICS codes 236210 (industrial building construction), 332812 (metal coating), and 339999 (miscellaneous manufacturing). As a stormwater outfall, it is part of the broader network of regulated discharges under the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits, which govern stormwater quality in urbanized areas. In the United States, stormwater outfalls like this one are subject to Phase II MS4 requirements for small municipalities and industrial facilities, which mandate the development of stormwater management programs to reduce pollutant loads. The facility's location in an industrial area suggests that runoff may contain sediments, metals, or other contaminants typical of manufacturing and construction sites. The regulatory framework requires monitoring and best management practices to protect receiving waters. The environmental significance of this outfall lies in its potential impact on local water bodies in the Cahaba River watershed, which is a critical source of drinking water and habitat for aquatic species. Proper management of stormwater discharges helps prevent erosion, flooding, and pollution, supporting community water quality and ecosystem health. The facility's compliance with NPDES permit conditions is essential for minimizing its footprint on the surrounding environment.

The facility is located in Trussville, Alabama, within the Cahaba River watershed, a region known for its high biodiversity and importance as a drinking water source. Stormwater runoff from industrial and commercial areas can carry pollutants such as heavy metals, oils, and sediments, which may impair water quality if not properly managed. The local climate, with frequent thunderstorms, increases runoff volumes and the risk of combined sewer overflows. Regulatory oversight under the Clean Water Act and Alabama's NPDES program aims to mitigate these impacts through stormwater management plans and best management practices.
