Overview
CLAY PIT #2 is a stormwater outfall in Mobile County, Alabama, United States. It serves an industrial catchment associated with NAICS 212321 (Construction Sand and Gravel Mining).
CLAY PIT #2 is a stormwater outfall located in Mobile County, Alabama, approximately 1 mile west of Grand Bay on Highway 90, crossing the railroad on Paul Ward Road. The facility operates under the regulatory framework of the US EPA NPDES MS4 program, which governs stormwater discharges in urbanized areas and industrial catchments. As a stormwater outfall, it manages runoff from a site classified under NAICS 212321, indicating construction sand and gravel mining operations. In the United States, stormwater outfalls like CLAY PIT #2 are subject to the Clean Water Act and typically require NPDES permits for discharges to waters of the U.S. The facility's location in Mobile County places it within the jurisdiction of the Alabama Department of Environmental Management (ADEM) for permitting and compliance. Stormwater management in this region often addresses sediment control and erosion prevention due to the area's sandy soils and proximity to coastal waterways. The environmental significance of CLAY PIT #2 lies in its role in managing runoff from industrial activities that could impact local water quality. Proper operation helps prevent sedimentation and pollutant loading into nearby streams and rivers, which ultimately drain into the Mobile Bay estuary. The facility contributes to the broader stormwater infrastructure that protects aquatic habitats and supports community water resources in the Gulf Coast region.
Environmental context
The Mobile County area features a humid subtropical climate with high annual rainfall, making stormwater management critical for flood control and water quality. The region's sandy soils and coastal location mean that runoff from industrial sites like CLAY PIT #2 can carry sediment and pollutants into sensitive waterways, including the Mobile Bay estuary. Effective stormwater treatment helps protect aquatic ecosystems and supports compliance with the Clean Water Act.
