Delta Asphalt of Arkansas, Inc.-Ash Flat Stormwater Outfall, Ash Flat, Arkansas

Delta Asphalt of Arkansas, Inc.-Ash Flat is a stormwater outfall located in Ash Flat, Sharp County, Arkansas, United States. The facility is operational and classified under NAICS code 324121, which corresponds to asphalt paving mixture and block manufacturing. As an industrial stormwater outfall, it manages runoff from the asphalt plant site, discharging into local waterways. In the United States, industrial stormwater discharges are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES). Facilities like this one typically require an NPDES permit for stormwater discharges associated with industrial activity, which includes monitoring and best management practices to control pollutants. The Arkansas Department of Energy and Environment - Division of Environmental Quality (DEQ) administers the NPDES program in the state. The environmental significance of this outfall lies in its potential to affect water quality in nearby receiving waters. As an asphalt facility, stormwater runoff may contain pollutants such as sediment, oils, and heavy metals. Proper management through permit compliance and pollution prevention measures is essential to protect local streams and rivers in the Spring River watershed area.

The facility is located in Sharp County, Arkansas, within the Spring River watershed. The region experiences a humid subtropical climate with moderate rainfall, which can generate significant stormwater runoff from industrial sites. Local water bodies may be sensitive to pollutants from asphalt production, including hydrocarbons and suspended solids. Regulatory oversight under the NPDES program aims to minimize these impacts through stormwater pollution prevention plans and regular monitoring.
