Wolf Creek Sand & Gravel Quarry Stormwater Outfall, Antoine, Arkansas

Wolf Creek Sand & Gravel Quarry is a stormwater outfall facility situated at 882 Wildcat Rd in Antoine, Pike County, Arkansas, United States. The facility is operational and falls under the industrial stormwater discharge sector, specifically associated with NAICS code 212319 (Other Crushed and Broken Stone Mining and Quarrying). As a quarry operation, it manages stormwater runoff from mining and processing areas. In the United States, industrial stormwater discharges are regulated under the Clean Water Act through the National Pollutant Discharge Elimination System (NPDES). Facilities like this quarry must obtain permit coverage, typically under the Multi-Sector General Permit (MSGP) for industrial activities. The permit requires implementation of stormwater pollution prevention plans (SWPPPs) and best management practices (BMPs) to control pollutants in runoff. The environmental significance of this outfall lies in its potential to discharge sediment, metals, and other quarry-related pollutants into local waterways. Proper management of stormwater at mining sites is critical to protect water quality in the surrounding watershed. The facility's location in rural Arkansas suggests that receiving waters may include streams and rivers that support aquatic ecosystems and downstream uses.

The quarry is located in Pike County, Arkansas, a region characterized by forested hills and numerous small streams that feed into larger river systems like the Little Missouri River. Stormwater runoff from mining operations can carry sediment, heavy metals, and other pollutants that may impair water quality. Effective stormwater management is essential to prevent degradation of these aquatic habitats and to comply with water quality standards under the Clean Water Act.
