CARMAN, INC. - FT. SMITH YARD Stormwater Outfall, Fort Smith, Arkansas

CARMAN, INC. - FT. SMITH YARD is a stormwater outfall located at 6705 HWY 271 S in Fort Smith, Sebastian County, Arkansas. The facility is operational and classified under NAICS code 484121 (General Freight Trucking, Long-Distance, Truckload), indicating an industrial catchment area. As a stormwater outfall, it manages runoff from the facility's yard and associated impervious surfaces. In the United States, stormwater discharges from industrial facilities are regulated under the Clean Water Act through NPDES permits, including Multi-Sector General Permits (MSGP) for industrial stormwater. Facilities like this one must implement stormwater pollution prevention plans (SWPPPs) and monitor discharge quality to protect receiving waters. The outfall likely discharges to a local waterbody, potentially the Arkansas River or a tributary, given Fort Smith's location. The environmental significance of this outfall lies in its role in managing runoff from a trucking yard, which may contain pollutants such as sediment, oil, grease, and heavy metals. Proper management is essential to prevent degradation of local water quality. The facility's compliance with NPDES requirements helps mitigate risks to downstream ecosystems and community water resources.

Fort Smith is located in the Arkansas River Valley, with the Arkansas River flowing nearby. The region experiences a humid subtropical climate with significant rainfall, increasing the potential for stormwater runoff. Industrial facilities like this trucking yard can contribute pollutants such as sediment, hydrocarbons, and metals to local waterways if not properly managed. The outfall's discharge likely enters a tributary of the Arkansas River, which is a major waterway supporting aquatic life and downstream water uses.
