Vulcan Construction Materials - Blakely Island Sales Yard Stormwater Outfall, Mobile, Alabama

Vulcan Construction Materials - Blakely Island Sales Yard is a stormwater outfall located at 1767 Cochrane Bridge Causeway in Mobile, Alabama, United States. This facility manages stormwater runoff from a construction materials sales yard, operating under the regulatory framework of the US EPA NPDES MS4 program. As a stormwater outfall, it discharges collected runoff into nearby water bodies, likely the Mobile River or Mobile Bay. The facility operates under a National Pollutant Discharge Elimination System (NPDES) permit, which sets limits on pollutants in stormwater discharges. The NAICS codes (212312, 237990, 423320) indicate activities related to crushed stone mining, utility construction, and construction materials wholesaling, suggesting the site handles heavy equipment and materials that may contribute sediment or other pollutants to runoff. Typical stormwater management at such facilities includes sediment basins, oil-water separators, and erosion controls. This outfall is part of the broader stormwater infrastructure in Mobile County, which serves a coastal urban area with significant industrial activity. Proper management of stormwater discharges is critical to protect water quality in Mobile Bay, an ecologically important estuary. The facility's compliance with its NPDES permit helps minimize impacts on local waterways.

The outfall discharges into the Mobile Bay watershed, a large estuary that supports diverse aquatic life and commercial fisheries. Urban and industrial runoff from Mobile can carry pollutants like sediment, heavy metals, and hydrocarbons. The facility's location on Cochrane Bridge Causeway near the bay makes its discharge quality important for maintaining the health of this sensitive coastal ecosystem.
