READY MIX USA- DEMOPOLIS FACILITY Stormwater Outfall, Demopolis, Alabama

READY MIX USA- DEMOPOLIS FACILITY is a stormwater outfall located at 302 Maria Ave in Demopolis, Alabama, within Marengo County. The facility is operational and classified under NAICS code 327320 (Ready-Mix Concrete Manufacturing), indicating an industrial catchment area. As a stormwater outfall, it manages runoff from the concrete production site, discharging into local water bodies. The facility operates under the US EPA NPDES MS4 permit framework, which regulates stormwater discharges from industrial facilities. Given its industrial nature, the outfall is subject to stormwater pollution prevention plans (SWPPP) and monitoring requirements to control pollutants like sediment, pH, and concrete washout. The facility's scale is typical for a ready-mix concrete plant, with moderate stormwater flow volumes. Environmental significance lies in its discharge to the Tombigbee River watershed, which supports aquatic habitats and downstream communities. Proper stormwater management at this facility helps prevent erosion, sedimentation, and chemical runoff, aligning with Clean Water Act goals. The facility's compliance with NPDES permits is critical for protecting local water quality.

The facility discharges stormwater into the Tombigbee River basin, a major waterway in Alabama that supports diverse aquatic life and provides drinking water. The industrial catchment, involving concrete production, poses risks of sediment, pH fluctuations, and heavy metal runoff. Regulatory oversight under the Clean Water Act and Alabama's NPDES program aims to mitigate these impacts through best management practices and monitoring.
