READY MIX USA - PELHAM FACILITY Stormwater Outfall, Pelham, Alabama

READY MIX USA - PELHAM FACILITY is a stormwater outfall located at 2486 Simmsville Road in Pelham, Shelby County, Alabama. This facility manages stormwater runoff from a ready-mix concrete manufacturing operation, classified under NAICS 327320. As an industrial stormwater outfall, it is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework, specifically under the Multi-Sector General Permit (MSGP) for industrial activities. The facility operates within the regulatory context of the Clean Water Act, which requires stormwater discharges from industrial sites to obtain NPDES permit coverage. The ready-mix concrete sector typically involves stormwater management practices such as sediment basins, silt fences, and proper storage of raw materials to prevent pollutant runoff. The facility's location in Pelham, a suburban area near Birmingham, places it within a region with moderate rainfall, necessitating effective stormwater controls to protect local water quality. Environmental significance lies in the facility's role in managing industrial stormwater to prevent contamination of nearby water bodies. The ready-mix concrete industry can generate stormwater pollutants like sediment, pH-elevated runoff, and concrete washout. Compliance with NPDES permit requirements, including regular monitoring and best management practices, is critical to minimizing environmental impact. The facility contributes to the broader stormwater management infrastructure in Shelby County, supporting local water quality goals.

Pelham, Alabama, experiences a humid subtropical climate with significant rainfall, averaging about 55 inches annually. Stormwater runoff from industrial sites like ready-mix concrete plants can carry pollutants such as sediment, heavy metals, and high pH levels into local waterways. The facility's discharge likely enters a tributary of the Cahaba River, a biologically diverse river system. Regulatory oversight under the EPA's NPDES MSGP ensures that industrial stormwater outfalls implement best management practices to minimize environmental harm.
