Document Description
Project is the expansion of an existing 113.5-acre aggregate mine site and reclamation plan to encompass an additional 356 acres for a total of 469.5 acres. 178 acres of the total will be preserved as habitat for desert tortoise and other species. The plan includes a new excavation pit, a new lime marination plant, expanded storage capacity, an increase in annual aggregate production from 330,000 tons to 450,000 tons, and a new closure date of 2092. Reclamation activity will be concurrent with the project. At closure, the site would be restored to unirrigated open space, retention basin for flood control, and wildlife habitat.
