GRICE DIRT PIT #1 Stormwater Outfall, Chastang, Alabama | US Stormwater Management

GRICE DIRT PIT #1 is a stormwater outfall located in Chastang, Alabama, within Mobile County. As a stormwater outfall, it functions as a discharge point for stormwater runoff from the surrounding area, which includes industrial and urban catchments typical of the region. The facility is operational and falls under the regulatory oversight of the US Clean Water Act and the EPA's NPDES MS4 permit program, which governs stormwater discharges in municipal separate storm sewer systems. The facility's NAICS code (212321) indicates it is associated with construction sand and gravel mining, suggesting the outfall may serve an industrial catchment related to mining activities. Stormwater outfalls in such contexts are designed to manage runoff from disturbed surfaces, controlling sediment and pollutant loads before discharge into receiving waters. The regulatory framework for this facility likely includes compliance with effluent limitations and best management practices to protect water quality. Located in the Gulf Coast region, the outfall discharges into local waterways that may ultimately drain to the Mobile Bay or Gulf of Mexico. Effective stormwater management at this site is important for mitigating impacts on downstream aquatic ecosystems, particularly given the region's vulnerability to heavy rainfall events and flooding. The facility's role in controlling runoff from industrial activities contributes to broader community and environmental protection efforts.

The stormwater outfall is situated in Mobile County, Alabama, within the Gulf Coast region, which experiences high annual rainfall and is prone to flooding. Discharges from this outfall may enter water bodies that are part of the Mobile Bay watershed, an ecologically significant estuary. The surrounding area includes industrial mining operations, which can contribute sediment and pollutants to stormwater runoff. Regulatory oversight under the Clean Water Act and NPDES MS4 permits aims to minimize these impacts through erosion control and water quality monitoring.
