Tyson Poultry - Spadra Feedmill Stormwater Outfall, Clarksville, Arkansas

Tyson Poultry - Spadra Feedmill is a stormwater outfall located at 1700 S Crawford St, Clarksville, Arkansas, within Johnson County. This facility manages stormwater runoff from a large-scale poultry processing and feedmill operation, operating under the US EPA's National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit framework. As a Phase II small MS4, it is subject to regulations aimed at reducing pollutant discharges to the maximum extent practicable. The facility's stormwater management system is designed to handle runoff from industrial activities classified under NAICS codes 311110 (Animal Food Manufacturing), 311119 (Other Animal Food Manufacturing), and 311611 (Animal Slaughtering and Processing). Typical stormwater controls may include detention basins, oil-water separators, and vegetated swales to treat runoff before discharge. The regulatory context in Arkansas involves compliance with the Clean Water Act and state-level permits issued by the Arkansas Department of Energy and Environment. This outfall plays a critical role in protecting local water quality in the Arkansas River basin, which receives stormwater discharges from the facility. Given the industrial nature of the catchment, the facility must implement best management practices (BMPs) to prevent pollutants such as nutrients, sediments, and organic matter from entering waterways. Effective stormwater management here supports both regulatory compliance and the ecological health of downstream water bodies.

The facility is located in the Arkansas River watershed, which supports diverse aquatic habitats and is used for recreation and water supply. Stormwater runoff from industrial sites like this feedmill can carry pollutants such as nitrogen, phosphorus, and organic matter, potentially contributing to eutrophication and oxygen depletion in receiving waters. The region's climate, with seasonal heavy rainfall, increases the risk of runoff events, making proper stormwater management essential to protect water quality.
