READY MIX USA WINFIELD PLANT Stormwater Outfall, Winfield, Alabama

READY MIX USA WINFIELD PLANT is a stormwater outfall located in Winfield, Marion County, Alabama, United States. 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 industrial stormwater discharges to be covered by an NPDES permit. The ready-mix concrete sector typically involves management of runoff from aggregate storage, truck washout areas, and concrete production processes. Best management practices (BMPs) such as sediment basins, filtration, and pH adjustment are commonly employed to control pollutants like total suspended solids (TSS) and elevated pH. Environmental significance of this outfall lies in its potential impact on local water quality in Marion County. Stormwater discharges from industrial sites can carry pollutants that affect receiving waters. The facility's compliance with its NPDES permit and implementation of stormwater pollution prevention plans (SWPPP) are critical for minimizing ecological impacts. Proper management ensures protection of downstream water bodies and adherence to federal and state water quality standards.

The facility is located in Winfield, Alabama, within the watershed of the Tombigbee River basin. Industrial stormwater discharges from ready-mix concrete operations can introduce sediment, metals, and alkaline pH levels into local waterways. The region's climate, with frequent rainfall events, increases the potential for runoff-related pollution. Effective stormwater management is essential to protect aquatic habitats and comply with the Clean Water Act's goal of restoring and maintaining water quality.
