NELSON RD PIT 1 Stormwater Outfall, Grand Bay, Alabama

NELSON RD PIT 1 is a stormwater outfall located at 11201 Nelson Rd in Grand Bay, Alabama, within Mobile County. As a stormwater outfall, it manages runoff from the surrounding area, contributing to local flood control and water quality management. The facility is operational and falls under the regulatory oversight of the US EPA's NPDES MS4 program, which governs stormwater discharges in urbanized areas. The facility's NAICS code (212321) indicates it is associated with construction sand and gravel mining, suggesting the outfall may serve an industrial catchment. In the United States, stormwater outfalls like this one are typically permitted under Phase II MS4 permits for small municipalities or industrial facilities, requiring compliance with stormwater pollution prevention plans. The specific design capacity or discharge volume is not detailed, but the facility's location in a coastal region of Alabama implies a focus on managing runoff to protect local waterways. Environmental significance lies in its role in mitigating stormwater impacts on nearby water bodies, such as the Mobile Bay estuary. Proper operation helps reduce flooding and pollutant loads, supporting local water quality goals. The facility's context within Mobile County highlights the importance of stormwater infrastructure in growing suburban areas, where development increases impervious surfaces and runoff volumes.

The facility is located in Grand Bay, Alabama, near the Mobile Bay estuary, a sensitive coastal ecosystem. Stormwater runoff from urban and industrial areas can carry pollutants like sediment, nutrients, and heavy metals into local waterways. The outfall's operation under NPDES MS4 regulations aims to minimize these impacts through best management practices, such as erosion control and sediment basins, to protect water quality in the region.
