Sibert Yard Stormwater Outfall, Mobile, Alabama | United States

Sibert Yard is a stormwater outfall located at the end of Industrial Canal Road in Mobile, Alabama, United States. It is part of the stormwater management infrastructure for the Mobile area, handling runoff from industrial and urban catchments. The facility is operational and falls under the regulatory framework of the US Clean Water Act, specifically the NPDES MS4 permit program for Phase I and Phase II municipalities. As a stormwater outfall, Sibert Yard discharges collected stormwater into receiving waters, likely the Mobile River or Mobile Bay. The facility's NAICS code 482111 indicates its association with rail transportation, suggesting the outfall serves an industrial area with potential for pollutant loads typical of such settings. Stormwater outfalls in Alabama are regulated by the Alabama Department of Environmental Management (ADEM) under delegated authority from the EPA. The environmental significance of Sibert Yard lies in its role in managing urban and industrial stormwater runoff, which can carry pollutants such as sediments, heavy metals, and hydrocarbons. Proper operation and maintenance of this outfall help protect water quality in downstream water bodies, including ecologically important estuaries like Mobile Bay. Compliance with NPDES permit conditions is critical to minimizing impacts on aquatic life and recreational uses.

Mobile, Alabama, is located on the Gulf Coast with a humid subtropical climate, receiving heavy rainfall that generates significant stormwater runoff. The area includes industrial zones along the Mobile River and Mobile Bay, which are ecologically sensitive estuaries supporting diverse aquatic life. Stormwater outfalls like Sibert Yard must manage runoff from impervious surfaces and industrial activities to prevent pollution of these water bodies. Regulatory oversight under the Clean Water Act and ADEM ensures that discharges meet water quality standards to protect aquatic ecosystems and public health.
