SEMO Operating Company, LLC DBA Near Ready Mix - Blytheville Stormwater Outfall, Arkansas

SEMO Operating Company, LLC DBA Near Ready Mix - Blytheville is a stormwater outfall located at 290 Cotton Road in Blytheville, Mississippi County, Arkansas. This facility manages stormwater discharge from a ready-mix concrete operation, classified under NAICS 327320. As a stormwater outfall, it is part of the broader network of regulated point sources under the US Clean Water Act. The facility operates under the National Pollutant Discharge Elimination System (NPDES) framework, which governs stormwater discharges from industrial activities. Given its industrial catchment, the outfall is subject to EPA's Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity. The facility's location in the Mississippi River floodplain influences local drainage patterns and potential downstream impacts. Stormwater management at this site is critical for controlling runoff from concrete production, which can contain sediment, pH-altering materials, and other pollutants. Effective treatment and monitoring help protect local water quality in the Mississippi River watershed. The facility's compliance with NPDES permit conditions ensures that stormwater discharges meet applicable water quality standards.

The facility is located in the Mississippi River alluvial plain, an area with flat topography and high agricultural activity. Stormwater runoff from industrial sites like ready-mix concrete operations can carry suspended solids, elevated pH, and trace metals. The Mississippi River and its tributaries are major water resources, and discharges must comply with state water quality standards to prevent impairment. The region experiences seasonal heavy rainfall, increasing the risk of runoff events that could impact downstream ecosystems.
