PHILLIPS SALVAGE Stormwater Outfall | Carlisle, Arkansas, United States

PHILLIPS SALVAGE is a stormwater outfall located at 819 South Greenlaw in Carlisle, Lonoke County, Arkansas, United States. The facility is operational and serves as a point of discharge for stormwater runoff from an industrial salvage operation, which is a common source of potential pollutants in stormwater. As a stormwater outfall in the United States, this facility operates under the Clean Water Act and is likely subject to National Pollutant Discharge Elimination System (NPDES) permit requirements, particularly the Multi-Sector General Permit (MSGP) for industrial activities. The Arkansas Department of Energy and Environment - Division of Environmental Quality (DEQ) oversees compliance with state and federal stormwater regulations. Typical controls include best management practices (BMPs) such as sediment basins, oil-water separators, and regular monitoring. The environmental significance of this outfall lies in its potential impact on local water bodies. Stormwater runoff from industrial sites can carry pollutants like heavy metals, hydrocarbons, and sediments. Proper management and treatment are essential to protect the water quality of receiving streams in the Arkansas River basin, which supports aquatic life and downstream communities.

Carlisle, Arkansas, is located in the Mississippi Alluvial Plain, an area with flat topography and clay-rich soils that can increase runoff. The region experiences a humid subtropical climate with frequent heavy rainfall, which can exacerbate stormwater runoff volumes and pollutant loads. The facility's discharge likely enters a tributary of the Arkansas River, which is a major waterway in the region. Industrial stormwater outfalls like this one are regulated to prevent contamination of surface waters, particularly from metals and hydrocarbons associated with salvage operations.
