Georgia-Pacific Sawmill Stormwater Outfall, El Dorado, Arkansas

Georgia-Pacific Sawmill is an industrial stormwater outfall located in El Dorado, Union County, Arkansas, United States. The facility manages stormwater runoff from sawmill and related industrial activities, operating under the US EPA's NPDES MS4 permit framework for industrial stormwater discharges. As a sawmill facility, the stormwater outfall handles runoff from industrial surfaces, including log yards, processing areas, and vehicle access roads. The facility's NAICS codes (236210, 321113, 321912) indicate activities in industrial building construction, sawmills, and cut stock manufacturing, which generate stormwater with potential pollutants like sediment, wood debris, and fuel residues. The outfall is subject to Clean Water Act requirements for industrial stormwater permits, including stormwater pollution prevention plans (SWPPP) and best management practices (BMPs). Located in southern Arkansas, the facility discharges into local waterways that are part of the Ouachita River basin. The region's climate includes significant rainfall, making stormwater management critical to prevent erosion and pollutant transport. The facility's operational status and regulatory compliance contribute to local water quality protection in an area with mixed industrial and agricultural land use.

The facility is situated in Union County, Arkansas, within the Ouachita River watershed, which supports diverse aquatic habitats. Industrial stormwater discharges from sawmill operations can carry sediment, organic matter, and hydrocarbons, potentially impacting receiving water bodies if not properly managed. The region experiences heavy rainfall events, increasing runoff volumes and the risk of pollutant mobilization. Regulatory oversight under the Clean Water Act requires the facility to implement erosion control, sediment management, and spill prevention measures to protect downstream water quality.
