RIVIANA FOODS - CARLISLE is a stormwater outfall located at 400 West Main Street in Carlisle, Lonoke County, Arkansas. The facility is part of the Riviana Foods rice milling operations, classified under NAICS 311212 (Rice Milling). As an industrial stormwater outfall, it manages runoff from the facility's premises and is subject to the US EPA's NPDES MS4 permitting framework. The outfall operates under the regulatory oversight of the Arkansas Department of Energy and Environment, which implements the Clean Water Act's stormwater program for industrial facilities. The site's stormwater management likely includes best management practices (BMPs) such as sediment basins, oil-water separators, or vegetative swales to control pollutants common in food processing runoff, including organic matter and nutrients. This outfall contributes to local stormwater management in the Carlisle area, a small agricultural community. The facility's discharge may affect nearby water bodies, including the Arkansas River watershed. Proper operation ensures compliance with water quality standards and protects downstream ecosystems from industrial runoff impacts.
Environmental context
The outfall is located in the Arkansas River basin, where stormwater runoff from industrial facilities can carry pollutants like sediments, nutrients, and organic matter. Carlisle's agricultural setting means local water bodies may already be sensitive to nutrient loading. The facility's rice milling operations generate process-related runoff that requires careful management to prevent water quality degradation.
