PLANT #4-DEQUEEN ASPHALT PLANT Stormwater Outfall, DeQueen, Arkansas

PLANT #4-DEQUEEN ASPHALT PLANT is a stormwater outfall located at 170 W Robinson Rd in DeQueen, Sevier County, Arkansas. This facility manages stormwater runoff from an industrial asphalt plant, classified under NAICS 324121 (Asphalt Paving Mixture and Block Manufacturing). As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state regulations. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) permitting framework, specifically the Construction General Permit (CGP) or Multi-Sector General Permit (MSGP) for industrial activities. Stormwater outfalls at industrial sites must implement best management practices (BMPs) to control pollutants such as sediment, oils, and chemicals. The Arkansas Department of Energy and Environment - Division of Environmental Quality (DEQ) oversees compliance with the Clean Water Act. This outfall is part of a network managing stormwater from asphalt production, which can involve exposure to heated materials and vehicle traffic. Proper management reduces the risk of contaminating nearby water bodies. The facility's location in southwestern Arkansas places it in a region with clay soils and moderate rainfall, where erosion control is a key concern for stormwater quality.

The facility is located in Sevier County, Arkansas, within the Red River watershed. The region experiences a humid subtropical climate with annual rainfall averaging 50 inches, leading to significant stormwater runoff. Industrial sites like asphalt plants can contribute pollutants such as suspended solids, hydrocarbons, and heavy metals. The outfall discharges to unnamed tributaries that flow into the Little River, which is part of the larger Red River basin. Effective stormwater management is critical to protect aquatic habitats and downstream water quality, especially given the potential for industrial contaminants.
