LANXESS CORP - CENTRAL PLANT Stormwater Outfall, El Dorado, Arkansas

LANXESS CORP - CENTRAL PLANT is a stormwater outfall located at 2226 Haynesville Hwy in El Dorado, Union County, Arkansas. This facility manages stormwater discharge from an industrial chemical manufacturing site, with NAICS codes indicating activities in industrial building construction, water and sewer line construction, and various chemical manufacturing sectors. As a stormwater outfall, it is part of the broader stormwater management infrastructure for the LANXESS Corporation's central plant. The facility operates under the regulatory framework of the US Clean Water Act, specifically through the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. In Arkansas, stormwater discharges from industrial facilities are typically regulated under NPDES industrial stormwater permits, which require compliance with effluent limitations and best management practices to control pollutants. The plant's location in an industrial catchment area means it handles runoff from chemical manufacturing processes, necessitating robust treatment and monitoring. This stormwater outfall plays a critical role in managing runoff from the LANXESS central plant, helping to prevent flooding and reduce pollutant loads to receiving waters. The facility's operational status ensures ongoing management of stormwater quality and quantity, contributing to local environmental protection and regulatory compliance. Its location in El Dorado, a city with a strong industrial base, underscores the importance of effective stormwater management in industrial settings.

The stormwater outfall discharges into receiving waters in the Ouachita River basin, which supports diverse aquatic ecosystems. Industrial stormwater runoff from chemical manufacturing can contain pollutants such as heavy metals, organic compounds, and suspended solids. The facility's compliance with NPDES permit conditions is essential to protect water quality in downstream water bodies, which may be used for drinking water, recreation, and habitat.
