UNITED PARCEL SERVICE - FORT SMITH Stormwater Outfall, Fort Smith, Arkansas

UNITED PARCEL SERVICE - FORT SMITH is a stormwater outfall located at 6715 South 28th Street in Fort Smith, Sebastian County, Arkansas. This facility manages stormwater runoff from an industrial site classified under NAICS 492110 (Couriers and Express Delivery Services). As a stormwater outfall, it discharges collected runoff into local waterways, operating under the regulatory framework of the US Clean Water Act and EPA's NPDES MS4 permit program. The facility's stormwater management is subject to Phase II MS4 requirements applicable to small municipalities and industrial sites in Arkansas. The outfall likely includes best management practices such as detention basins, oil-water separators, or vegetated swales to treat runoff before discharge. Given the industrial nature of the site, the stormwater may contain pollutants typical of transportation and logistics operations, including sediment, oil and grease, and heavy metals. This outfall contributes to the stormwater infrastructure of Fort Smith, a city in the Arkansas River Valley. Proper management of stormwater discharges is critical to protect the water quality of receiving streams, which ultimately flow into the Arkansas River. The facility's compliance with NPDES permit conditions helps mitigate the impact of urban runoff on local aquatic ecosystems.

Fort Smith is located in the Arkansas River Valley, a region with a humid subtropical climate and significant rainfall, leading to substantial stormwater runoff. The outfall discharges into local streams that are part of the Arkansas River watershed. Industrial stormwater runoff from facilities like this UPS site can carry pollutants such as sediment, oil, grease, and metals, which may impair water quality if not properly managed. The facility operates under an NPDES MS4 permit, requiring implementation of stormwater control measures to minimize environmental impact.
