Project Applicant
Panamint Valley Limestone, Inc.
Present Land Use
Site is currently vacant and previously used as an ash disposal site. GP/Zoning is IR (Regional Industrial)

Document Description
The proposed use is a lime processing plant. Limestone in the form of crushed rock will be transported to the site where it will be converted into quicklime and transported to other locations. On-site facilities include the lime plant, office building, pellet plant, limestone powder plant, solar power generation array, loading bins, vertical kiln, conveyors, water storage tank, paved internal roadways, storm water basin, and other ancillary facilities. The proposed project requires a Conditional Use Permit for its operation and a Variance due to the height of the air emissions control stack.
