Gulf States Ready-Mix Plant 30 Stormwater Outfall, Semmes, Alabama

Gulf States Ready-Mix Plant 30 is a stormwater outfall located at 1540 Schillinger Rd N, Semmes, Alabama, in Mobile County. It serves the ready-mix concrete manufacturing sector (NAICS 327320) and is currently operational. As a stormwater outfall, it manages runoff from industrial facilities, which is regulated under the US Clean Water Act. The facility operates within the regulatory framework of the US EPA NPDES MS4 program, which requires permits for stormwater discharges from industrial activities. Alabama's Department of Environmental Management (ADEM) oversees compliance with state and federal stormwater regulations. The outfall likely handles runoff from concrete production areas, including process water and stormwater mixed with cementitious materials. Stormwater outfalls from concrete plants are significant due to the potential for high pH runoff and sediment discharge. Proper management helps protect local water bodies, such as those in the Mobile Bay watershed. The facility's location in a rapidly developing area underscores the importance of stormwater controls to mitigate environmental impacts.

The facility is located in Semmes, Alabama, within the Mobile Bay watershed, which drains into the Gulf of Mexico. Stormwater runoff from industrial sites like concrete plants can carry high pH levels, suspended solids, and heavy metals, potentially impacting aquatic ecosystems. The area experiences a subtropical climate with heavy rainfall, increasing runoff volumes. Regulatory oversight under the NPDES program aims to minimize these impacts through best management practices.
