GRANT GARRETT EXCAVATING, INC. - VAUGHN ASPHALT PLANT Stormwater Outfall in Bentonville, Arkansas

GRANT GARRETT EXCAVATING, INC. - VAUGHN ASPHALT PLANT is a stormwater outfall located at 8601 S Vaughn Rd in Bentonville, Benton County, Arkansas. The facility operates as an industrial stormwater discharge point for an asphalt plant, classified under NAICS codes 237310 (Highway, Street, and Bridge Construction) and 324121 (Asphalt Paving Mixture and Block Manufacturing). As a stormwater outfall, it is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting framework, specifically under the Clean Water Act's Industrial Stormwater Program. The facility operates under the regulatory oversight of the Arkansas Department of Energy and Environment - Division of Environmental Quality, which implements the NPDES program in the state. Industrial stormwater discharges from asphalt plants typically require coverage under a Multi-Sector General Permit (MSGP) or an individual permit, with requirements for stormwater pollution prevention plans (SWPPP), best management practices (BMPs), and monitoring of effluent limits for pollutants such as total suspended solids, oil and grease, and pH. As an industrial stormwater outfall in the rapidly developing region of Northwest Arkansas, the facility plays a role in managing runoff from construction and manufacturing activities. The outfall discharges to local waterways that ultimately feed into the Illinois River watershed, which is a focus of regional water quality efforts due to nutrient and sediment concerns. Proper stormwater management at this facility helps protect downstream aquatic habitats and comply with state water quality standards.

The facility is located in Bentonville, Arkansas, within the Illinois River watershed, which is subject to nutrient and sediment impairment concerns. Industrial stormwater runoff from asphalt plants can contain pollutants such as suspended solids, hydrocarbons, and heavy metals. The region's rapid urbanization increases impervious surfaces, potentially exacerbating runoff volumes and pollutant loads. Regulatory compliance under the NPDES Industrial Stormwater Program is critical to minimize impacts on receiving waters.
