DEQUEEN PVNG ASPHALT PLANT 453 Stormwater Outfall, DeQueen, Arkansas

DEQUEEN PVNG ASPHALT PLANT 453 is a stormwater outfall located in DeQueen, Sevier County, Arkansas, United States. The facility manages stormwater runoff from an asphalt plant site, operating under the regulatory framework of the US EPA's National Pollutant Discharge Elimination System (NPDES) and Clean Water Act. As a stormwater outfall, it is part of the broader municipal separate storm sewer system (MS4) that controls pollution from urban and industrial runoff. The facility's technical specifications are not detailed, but typical stormwater outfalls in industrial settings like asphalt plants manage runoff from impervious surfaces, vehicle fueling areas, and material storage. The site is subject to NPDES permitting for industrial stormwater discharges, which requires implementation of best management practices (BMPs) to reduce pollutants. In Arkansas, the Department of Energy and Environment oversees compliance with state and federal stormwater regulations. Environmental significance lies in the outfall's role in preventing untreated runoff from entering local waterways. The facility is located near the Oklahoma border, and its discharge may affect water quality in the Red River basin. Proper management of stormwater from asphalt plants is critical to avoid contamination from hydrocarbons, heavy metals, and sediments, protecting aquatic ecosystems and downstream water users.

The facility is situated in a region with a humid subtropical climate, characterized by frequent rainfall that generates substantial stormwater runoff. The outfall discharges into local waterways that are part of the Red River watershed, which supports diverse aquatic life and is used for recreation and water supply. Industrial stormwater from asphalt plants can contain pollutants such as oil, grease, and heavy metals, posing risks to water quality. Regulatory oversight under the Clean Water Act aims to minimize these impacts through NPDES permits and BMPs.
