WYATT QUARRY Stormwater Outfall, Calico Rock, Arkansas | United States

WYATT QUARRY is a stormwater outfall facility located at the end of Bory Road in Calico Rock, Izard County, Arkansas, United States. The facility is operational and serves as a discharge point for stormwater runoff from the surrounding area, which includes quarrying activities (NAICS 212321). As a stormwater outfall, it is part of the broader network of municipal separate storm sewer systems (MS4) regulated under the US Clean Water Act. The facility operates under the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting program, which governs stormwater discharges from industrial and municipal sources. In Arkansas, the Department of Energy and Environment - Division of Environmental Quality administers the NPDES program. Stormwater outfalls like WYATT QUARRY are subject to regulations that require controls to minimize pollutant runoff, particularly from industrial sites such as quarries. Environmental significance of this outfall relates to its potential impact on local water bodies. Stormwater runoff from quarry operations can carry sediment, metals, and other pollutants. The facility's location in a rural area of Arkansas means it may discharge to streams or rivers that are part of the White River watershed. Proper management of stormwater discharges is essential to protect water quality and aquatic habitats in the region.

The facility is located in a rural area of north-central Arkansas, within the Ozark Mountains region. Local water bodies are typically clear, spring-fed streams that support diverse aquatic life. Stormwater runoff from quarry operations can introduce sediment and turbidity, which may affect stream habitats. The area's karst geology means that surface water and groundwater are closely connected, increasing the importance of controlling stormwater discharges to prevent contamination of groundwater resources.
