This facility is part of the stormwater management infrastructure for the region, handling runoff from industrial and urban areas. The outfall operates under the regulatory framework of the US Clean Water Act, specifically the EPA's NPDES MS4 permit program, which governs stormwater discharges in municipalities and industrial sites. As a stormwater outfall, the facility's primary function is to convey collected stormwater runoff from the surrounding catchment to a receiving water body. The site is classified under NAICS code 213112 for support activities related to oil and gas operations, indicating an industrial context. The facility is operational and likely subject to monitoring and best management practices to control pollutants in stormwater discharge. The environmental significance of this outfall lies in its role in managing runoff from an industrial area in Union County, Arkansas. Proper stormwater management helps protect local water quality by reducing the transport of sediments, chemicals, and other pollutants into nearby streams and rivers. The facility contributes to the community's resilience against flooding and erosion, supporting both environmental and public health objectives.

The outfall is located in El Dorado, Arkansas, within the Ouachita River basin. The region experiences a humid subtropical climate with significant rainfall, making stormwater management critical for flood control and water quality. The industrial catchment, including oil and gas support activities, may contribute pollutants such as hydrocarbons and heavy metals to runoff. The facility's discharge likely enters a water body that is subject to state water quality standards, and compliance with NPDES permit conditions is essential to protect aquatic ecosystems.
