REYNCO Stormwater Outfall, El Dorado, Arkansas | United States

REYNCO is a stormwater outfall located at 510 Hinson Rd, El Dorado, Arkansas, within Union County. It operates under the US EPA NPDES MS4 permitting framework, which governs stormwater discharges from municipal separate storm sewer systems. As a stormwater outfall, it collects and discharges runoff from surrounding areas, primarily serving industrial catchments associated with NAICS codes 212321 (Construction Sand and Gravel Mining) and 488210 (Support Activities for Rail Transportation). The facility's operational status is active, and it is subject to Clean Water Act requirements for stormwater management. In Arkansas, stormwater outfalls like REYNCO must comply with state and federal regulations to control pollutants in runoff. The local industrial mix suggests potential for sediment, heavy metals, or hydrocarbon runoff, necessitating best management practices (BMPs) such as detention basins or filtration systems. Environmentally, the outfall may discharge to nearby water bodies, potentially impacting water quality in the Ouachita River basin. Proper stormwater management is critical to prevent erosion, flooding, and contamination of aquatic habitats. REYNCO's role in the local stormwater network helps mitigate these risks by conveying runoff safely while complying with permit limits.

El Dorado, Arkansas, lies in the Ouachita River basin, a region with mixed forest and industrial land use. Stormwater runoff from industrial sites can carry sediments, metals, and hydrocarbons, posing risks to local streams and the Ouachita River. The area experiences a humid subtropical climate with frequent heavy rainfall, increasing runoff volumes. Effective stormwater management is essential to protect water quality and aquatic ecosystems from urban and industrial pollution.
