APAC-CENTRAL INC,-GRAND AVENUE SAND PLANT Stormwater Outfall, Fort Smith, Arkansas

APAC-CENTRAL INC,-GRAND AVENUE SAND PLANT is a stormwater outfall located at 6600 Grand Ave in Fort Smith, Sebastian County, Arkansas. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, likely associated with industrial or sand processing activities given the plant name. The facility is operational and falls under the regulatory oversight of the United States Environmental Protection Agency (EPA) and the Arkansas Department of Environmental Quality. Stormwater outfalls in the United States are regulated under the National Pollutant Discharge Elimination System (NPDES) program, specifically through Municipal Separate Storm Sewer System (MS4) permits for Phase I and Phase II municipalities. Fort Smith, as an urbanized area, is subject to MS4 requirements that mandate stormwater management plans to reduce pollutant discharges to the maximum extent practicable. The facility's discharge may be subject to effluent limits or best management practices depending on its classification and the receiving water body. The environmental significance of this outfall lies in its potential impact on local water quality. Stormwater runoff from industrial and urban areas can carry pollutants such as sediment, heavy metals, and hydrocarbons. Proper management and monitoring of this outfall are essential to protect the water quality of nearby streams and rivers, which may ultimately drain into the Arkansas River or other regional water bodies. Compliance with NPDES permit conditions helps mitigate these risks.

Fort Smith is located in the Arkansas River Valley, a region characterized by a humid subtropical climate with significant rainfall, leading to substantial stormwater runoff. The area's industrial activities, including sand processing, can contribute pollutants such as sediment and hydrocarbons to stormwater discharges. The outfall's discharge likely enters a local waterway that may be impaired for sediment or other stressors, necessitating effective stormwater management under the Clean Water Act to protect aquatic ecosystems and downstream water quality.
