Overview
SEMCOA is a stormwater outfall in Bauxite, Arkansas, United States, serving the local drainage area. It operates under the US EPA NPDES MS4 permit framework.
SEMCOA is a stormwater outfall located on Mount Olive Road in Bauxite, Saline County, Arkansas, United States. As a stormwater outfall, it discharges collected stormwater runoff from the surrounding catchment into a receiving water body. The facility is operational and falls under the regulatory oversight of the US Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program, which governs stormwater discharges in urbanized areas. In Arkansas, stormwater management is regulated by the Arkansas Department of Energy and Environment - Division of Environmental Quality (DEQ), which implements the NPDES MS4 program. Facilities like SEMCOA are typically part of a larger network of outfalls that manage runoff from industrial, commercial, and residential areas. The NAICS code 212319 indicates the catchment may include mining-related activities, as Bauxite is historically associated with bauxite mining. The environmental significance of SEMCOA lies in its role in controlling the quality and quantity of stormwater discharge. Proper management helps prevent erosion, flooding, and pollution of local water bodies. The facility's location in Saline County, part of the Ouachita River basin, means its discharge could affect downstream water quality, making compliance with NPDES permits critical for protecting aquatic ecosystems.
Environmental context
The Bauxite area in Saline County, Arkansas, has a history of bauxite mining, which can contribute to sediment and metal loading in stormwater runoff. The region's climate, with frequent thunderstorms, generates significant runoff that must be managed to prevent erosion and flooding. The outfall discharges into a water body that is part of the Ouachita River basin, which supports diverse aquatic life. Effective stormwater treatment is essential to minimize impacts on water quality, particularly from suspended solids and potential contaminants associated with industrial land use.
