MOBLEY CONCRETE COMPANY Stormwater Outfall, Harrisburg, Arkansas

MOBLEY CONCRETE COMPANY is a stormwater outfall located at 1300 Freeman Road in Harrisburg, Poinsett County, Arkansas, United States. The facility manages stormwater runoff from a concrete manufacturing site (NAICS 327320) and is classified as a stormwater outfall. It operates under the regulatory framework of the US Clean Water Act, which governs discharges from industrial facilities through NPDES permits. As a concrete manufacturing facility, the stormwater outfall handles runoff from impervious surfaces and material storage areas, which may contain sediment and other pollutants typical of construction materials. The facility's location in eastern Arkansas places it within the Mississippi River watershed, where stormwater management is critical for protecting local water quality. Regulatory oversight likely involves compliance with EPA's Multi-Sector General Permit for industrial stormwater discharges. The environmental significance of this outfall lies in its role in preventing untreated runoff from entering nearby waterways. Concrete facilities often require best management practices such as sediment basins and erosion controls to minimize pollutant loads. The operational status of the outfall indicates ongoing management of stormwater to meet permit conditions and protect downstream aquatic habitats.

The facility is situated in Poinsett County, Arkansas, within the Mississippi River Alluvial Plain, an area characterized by intensive agriculture and periodic flooding. Stormwater runoff from industrial sites like concrete manufacturing can carry suspended solids, pH-altering substances, and heavy metals, posing risks to local streams and the larger Mississippi River ecosystem. Effective stormwater management is essential to prevent degradation of water quality in this region, which supports diverse aquatic life and agricultural water use.
