FEDEX FREIGHT FSM Stormwater Outfall, Fort Smith, Arkansas | United States

FEDEX FREIGHT FSM is a stormwater outfall located in Fort Smith, Sebastian County, Arkansas, United States. It serves industrial and transportation-related activities, handling stormwater runoff from freight and logistics operations. The facility is operational and falls under the regulatory oversight of the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. As a stormwater outfall, the facility manages runoff from impervious surfaces typical of industrial and transportation sites. The NAICS codes 484122 (General Freight Trucking, Long-Distance) and 488490 (Other Support Activities for Road Transportation) indicate the catchment includes trucking terminals and related infrastructure. Stormwater management at such sites often involves best management practices (BMPs) like detention basins, oil-water separators, and sediment controls to mitigate pollutant loads. The facility's location in Fort Smith, near the Arkansas River, places it in a region with potential downstream water quality concerns. Compliance with the Clean Water Act and local MS4 permits is critical to prevent discharge of pollutants to receiving waters. The outfall contributes to the broader stormwater management network in Sebastian County, supporting flood control and water quality protection.

The outfall discharges stormwater from an industrial catchment in Fort Smith, which may contain pollutants such as sediments, oils, and heavy metals from trucking and transportation activities. The receiving waters are likely tributaries of the Arkansas River, a major waterway in the region. Effective stormwater management is essential to protect aquatic habitats and comply with the Clean Water Act's goal of restoring and maintaining water quality.
