ROCK-IT NATURAL STONE Stormwater Outfall, Clarksville, Arkansas

ROCK-IT NATURAL STONE is a stormwater outfall facility located at 10841 HWY 164 in Clarksville, Johnson County, Arkansas, United States. The facility is operational and serves as a point of discharge for stormwater runoff from a stone mining and quarrying operation (NAICS 212311). As a stormwater outfall, it is part of the broader network of facilities managing runoff in the region. The facility operates under the regulatory framework of the United States Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) program. Stormwater discharges from industrial activities such as mining are typically regulated under NPDES permits, which require compliance with effluent limitations and monitoring requirements. The Arkansas Department of Energy and Environment - Division of Environmental Quality is the delegated authority for implementing the NPDES program in the state. Stormwater outfalls like ROCK-IT NATURAL STONE play a critical role in managing runoff from industrial sites to prevent pollution of receiving waters. The facility's location in the Arkansas River basin means its discharges could affect local water quality. Proper management of stormwater is essential to minimize erosion, sedimentation, and potential contamination from mining operations.

The facility is located in the Arkansas River basin, which supports diverse aquatic ecosystems and is used for recreation, water supply, and agriculture. Stormwater runoff from industrial sites like stone quarries can carry sediment, heavy metals, and other pollutants that may impair water quality. The region experiences seasonal rainfall patterns, with heavy precipitation events potentially increasing runoff volumes and pollutant loads. Effective stormwater management is critical to protect downstream water bodies from degradation.
