Moore Rock Quarry

Moore Rock Quarry

A modification and renewal of Conditional Use/Surface Mining Permits and approval of Reclamation Plan and review of financial assurance cost estimates for continued quarry operations of the Moore Rick Quarry. In 1992, the County permitted re-opening of the historic rock quarry and allowed extraction of up to 10,000 cubic yards every 2 years with a total removal volume of 70,000 cubic yards. Only half of the total volume of rock available has been removed. The current project proposes extraction and crushing of up to 10,000 cubic yards of rock as frequently as annually and will utilize an ~2.45 acres. Mining activties include extraction of rock from the quarry face, crushing and transporting crushed gravel to the stockpile near the road. Extraction is proposed to be accomplished by ripping and breaking up the rock with a bulldozer. In the event that localized graywacke boulders are encountered, small scale seperation with charges will be performed. Vegetation, including 10 trees, will be removed from the west side of the quarry. Equipment also includes crawler tractor, crusher unit, front-end loader and dump truck. The Couty Dept. of Public Works has a License Agreement with the land owner for activities associated with mining, crushing and stockpiling rock. The permit term is 15 yrs and will expire June 8, 2022.
