Gate Precast Company Stormwater Outfall, Monroeville, Alabama

Gate Precast Company is a stormwater outfall located at 2440 South Alabama Avenue in Monroeville, Monroe County, Alabama, United States. This operational facility manages stormwater runoff from a precast concrete manufacturing site, classified under NAICS 327390. As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state regulatory oversight. The facility operates within the framework of the US Clean Water Act, specifically under the National Pollutant Discharge Elimination System (NPDES) for industrial stormwater discharges. Given its industrial catchment, the outfall is likely covered by a Multi-Sector General Permit (MSGP) for the construction materials sector. Typical stormwater management at such sites includes sediment basins, oil-water separators, and erosion controls to mitigate pollutant loads. Environmental significance lies in its discharge to receiving waters in Alabama, which may include streams or rivers in the Mobile Bay watershed. Proper stormwater management is critical to prevent contamination from heavy metals, hydrocarbons, and suspended solids associated with concrete manufacturing. The facility contributes to local water quality protection by complying with permit limits and best management practices.

The outfall discharges stormwater from an industrial catchment in Monroeville, Alabama, a region with a humid subtropical climate and frequent rainfall. Runoff from the precast concrete facility may contain pollutants such as sediment, pH-elevated water, and trace metals. The receiving water body is part of the Alabama River basin, which ultimately drains to Mobile Bay, an ecologically important estuary. Effective stormwater management is essential to prevent impairment of these waters, particularly under the EPA's NPDES program, which requires monitoring and controls for industrial facilities.
