Document Description
Surface Mining Permits (SMP) 161, Revision No. 4 is an application to revise the existing permit to add a 10.5-acre material retail sales yard area on two small land parcels contiguous to the existing SMP 161R3 project area. This plan also proposes to increase maximum annual aggregate production from the currently authorized 900,000 tons per year to 1.8 million tons per year. Finally, on-site operating hours, for the block plant, will continue to involve the 24 hour operation of the concrete block plant seven days a week. Other than maintenance or emergencies, the remaining project site operations for excavation are limited to the hours between 6 am and 10 pm, Monday through Saturday. Truck and hauling operations shall be limited to the hours between 6 am and 9 pm, Monday through Saturday. All operations for excavation, trucking, or hauling of materials shall be prohibited on Sundays and Federal holidays. Mining is proposed to continue as currently approved under SMP 161R3 with maximum slopes of 80 feet in height, and average excavation depth of 70 feet. Maximum final cut and reclaimed slope inclinations are not to exceed 3:1 (H:V). Reclamation activities will commence annually in areas that will not be impacted by further mining activities. Upon completion of mining operations, all equipment and buildings will be removed and the site will be revegetated with native plant species and reclaimed as vacant open space. The project is located easterly of the intersection of Dillon Road and Berdoo Canyon Road, approximately 12 miles northeast of Indio, and approximately 4 miles southwest of the Joshua Tree National Park boundary.
