Hum Co DPW-Drewry Rock Quarry Conditional Use/Surface Mining Permits and Reclamation Plan

Description

A modification and renewal of a Conditional Use/Surface Mining Permits, approval of Reclamation Plan and review of financial assurance cost estimates for an existing surface mining operation known as the Drewry Rock Quarry and previously known as the Bell Springs Rock Quarry. THe term is 15 years and will expire in March 10, 2023. The site has historically been mined since 1993 by the Humboldt County Dept. of Public Works for a total of 30,807 cubic yards. The original permit allowed for annual extraction of 2,000 cubic yards for a total of 30,000 cubic yards and periodic use of a portable crusher 2 weeks annually. The modification proposes an annual extraction of up to 20,000 cubic yards with the total amount of extraction not to exceed 69,200 cubic yards. Operations include extraction, crushing and stockpiling. No washing and no asphalt/cement batch processing will be conducted on site. In the event localized greywacke boulders are encountered, small scale seperation with charges may be performed. No new access roads to the quarry will be constructed. Heavy equipment to be used on site includes: an excavator, a front end loader, and a portable rock crusher. The Humboldt County Dept. of Public Works has a License Agreement with the owner for activities associated with mining, crushing and stockpiling.
