CRYSTAL MOUNTAIN PIT Stormwater Outfall, Berryville, Arkansas

CRYSTAL MOUNTAIN PIT is a stormwater outfall located at 8316 Highway 21 S in Berryville, Arkansas, within Carroll County. The facility is operational and classified under NAICS code 212321, indicating a connection to construction sand and gravel mining operations. As a stormwater outfall, it manages runoff from industrial activities, ensuring compliance with local and federal water quality standards. The facility operates under the regulatory framework of the US Clean Water Act, specifically through the National Pollutant Discharge Elimination System (NPDES) permit program. Stormwater outfalls like this one are typically subject to Multi-Sector General Permits (MSGP) for industrial activities, which require monitoring and best management practices to control pollutants in runoff. The site's location in the Ozark region of Arkansas means it may handle runoff from karst topography, which can influence drainage patterns and groundwater recharge. Environmental significance includes the potential for discharge to nearby water bodies, such as tributaries of the White River system. Proper management of stormwater from mining operations is critical to prevent sedimentation and contamination of local streams. The facility's role in the community involves mitigating flood risks and protecting water quality in the region, supporting both ecological health and downstream water uses.

The facility is located in the Ozark Mountains region of Arkansas, characterized by karst geology with sinkholes and underground drainage. Stormwater runoff from mining operations can carry sediment and pollutants into sensitive aquatic ecosystems. The area's streams are part of the White River watershed, which supports diverse fish and wildlife. Regulatory oversight under the Clean Water Act aims to minimize impacts on these water bodies through NPDES permit conditions, including erosion control and water quality monitoring.
