This facility manages stormwater runoff from industrial operations, including iron foundries and industrial valve manufacturing (NAICS 331511, 332911, 332919). As a stormwater outfall, it is part of the regulated industrial stormwater discharge framework under the US Clean Water Act. The outfall operates under the National Pollutant Discharge Elimination System (NPDES) permitting program, which governs stormwater discharges from industrial activities. Facilities like NIBCO INC are required to implement Stormwater Pollution Prevention Plans (SWPPPs) and monitor discharge quality to comply with state and federal regulations. The Arkansas Department of Energy and Environment oversees compliance in this region. Stormwater management at industrial sites is critical for protecting local water quality. The outfall discharges into receiving waters that may drain to the Mississippi River watershed. Effective stormwater control helps prevent pollutants such as sediment, metals, and chemicals from entering waterways, supporting ecological health and community water resources.

The outfall is located in Mississippi County, Arkansas, an area with a mix of agricultural and industrial land use. The region's climate includes significant rainfall, which can increase stormwater runoff volumes and pollutant loads. Industrial stormwater discharges may contain metals, oils, and other contaminants from manufacturing processes. Compliance with NPDES permit limits is essential to protect downstream water bodies, including tributaries of the Mississippi River, which support diverse aquatic ecosystems and provide drinking water for communities.
