Greenbrier Ready Mix, Inc. Stormwater Outfall, Greenbrier, Arkansas | United States

Greenbrier Ready Mix, Inc. is a stormwater outfall located at 583 Highway 65 in Greenbrier, Faulkner County, Arkansas, United States. The facility is operational and serves an industrial catchment associated with ready-mix concrete manufacturing (NAICS 327320). As a stormwater outfall, it manages runoff from the industrial site, discharging into local waterways. The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) program. Stormwater discharges from industrial activities are typically regulated under Multi-Sector General Permits (MSGP) or individual permits. The facility's location in Arkansas places it under the jurisdiction of the Arkansas Department of Energy and Environment - Division of Environmental Quality, which implements the NPDES program in the state. Stormwater outfalls from industrial facilities like concrete batch plants can carry pollutants such as sediment, pH-elevated runoff, and heavy metals. Proper management through best management practices (BMPs) is essential to protect receiving waters. The facility's discharge likely enters a tributary of the Arkansas River basin, which supports regional water quality and aquatic habitats.

The facility is located in Faulkner County, Arkansas, within the Arkansas River basin. The region experiences a humid subtropical climate with significant rainfall, which can generate substantial stormwater runoff. Industrial stormwater discharges from concrete manufacturing can contain high pH levels, total suspended solids, and trace metals. The receiving waters may be subject to state water quality standards for aquatic life and recreation. Compliance with NPDES permit conditions, including effluent limits and monitoring requirements, is critical to minimize environmental impact.
