APAC-CENTRAL, BONANZA SITE Stormwater Outfall, Bonanza, Arkansas

APAC-CENTRAL, BONANZA SITE is a stormwater outfall located at HWY 45 SOUTH in Bonanza, Sebastian County, Arkansas, United States. This facility manages stormwater runoff from an industrial site classified under NAICS 212312 (Crushed and Broken Limestone Mining and Quarrying). As a stormwater outfall, it discharges collected stormwater into local waterways, operating under the regulatory oversight of the US Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) program. Stormwater outfalls like this one are subject to NPDES Multi-Sector General Permit (MSGP) requirements for industrial activities, which mandate stormwater pollution prevention plans (SWPPPs) and monitoring of discharge quality. The facility's location in a mining sector suggests potential pollutants include sediment, metals, and pH imbalances. Compliance with permit conditions is critical to minimize environmental impact. The outfall serves the Bonanza area in western Arkansas, a region with mixed urban and industrial land use. Proper stormwater management helps protect downstream water bodies, including the Arkansas River watershed, from pollution and flooding. The facility's operational status indicates ongoing management of stormwater runoff to meet regulatory standards.

The Bonanza site is located in the Arkansas River watershed, which supports diverse aquatic ecosystems and is used for recreation and water supply. Stormwater discharges from industrial facilities like this one can carry sediment, heavy metals, and other pollutants that may impair water quality. The region experiences seasonal rainfall, with potential for high-intensity storms that increase runoff volumes and pollutant loads. Effective stormwater management is essential to prevent erosion, sedimentation, and contamination of local streams and rivers.
