Auto Sales and Salvage Inc Stormwater Outfall, Caraway, Arkansas | US Stormwater Facility

Auto Sales and Salvage Inc is a stormwater outfall located at 9381 Hwy 135 South in Caraway, Arkansas, within Craighead County. The facility is operational and classified under NAICS code 441310 (Automotive Parts and Accessories Stores), indicating an industrial/commercial catchment that generates stormwater runoff requiring management. As a stormwater outfall in the United States, this facility operates under the Clean Water Act and is subject to EPA's NPDES MS4 permit framework. Depending on the municipality's designation, it may fall under Phase I or Phase II MS4 requirements, which mandate stormwater management plans to control pollution from urban and industrial runoff. The facility's location in a small city like Caraway suggests it likely operates under a Phase II small MS4 permit, focusing on best management practices for runoff quality. The environmental significance of this outfall lies in its contribution to local water quality in the Mississippi River Basin region. Stormwater runoff from automotive salvage yards can contain pollutants such as oil, grease, heavy metals, and sediment. Proper management ensures compliance with water quality standards and protects downstream water bodies, including nearby streams and the St. Francis River.

The facility is situated in the Mississippi Alluvial Plain, a region with flat topography and intensive agriculture, where stormwater runoff can carry sediments, nutrients, and industrial pollutants. The outfall discharges into local waterways that eventually feed the Mississippi River, making pollution control critical for downstream ecosystems. Arkansas's climate features frequent thunderstorms, leading to high runoff volumes that can exacerbate pollutant loading if not managed effectively.
