Project Information


PROJECT SUMMARYThe proposed Project consists of a revision to Surface Mining Permit No. 159 (SMP 159R2) for an existing aggregate mining site (Gilman Springs Mine). SMP159R2 proposes the following: 1) expand areas for mining by adding approximately 54.5 acres to the currently approved 150.4 acres of mining area, resulting in approximately 204.9 acres of mining area; 2) increase the total tonnage of minable aggregate from approximately 14,000,000 tons to 44,000,000 tons, an increase of approximately 30,000,000 tons; 3) allow for the operation of an IDEFO to facilitate ultimate site reclamation; 4) to establish a revised reclamation plan in compliance with the Surface Mining and Reclamation Act of (SMARA, Public Resources Code § 2710 et seq.) and Riverside County Code Riverside County Ordinance No. 555 (Surface Mining Reclamation Act) (Riverside County,  012); and 5) to revise the Mine’s timing restrictions for mining activities within 300 feet of the Mine’s boundaries from between 7:00 a.m. and 10:00 p.m., Monday through Saturday except holidays, to 24 hours per day, seven days per week including Sundays and federal holidays. The proposed Project also refers to the changes that would result from approval of the proposed Project, such as increased traffic and additional employees, pursuant to CEQA’s requirements for evaluating revisions to on-going permits.

PROJECT LOCATIONThe project is located within the Reche Canyon/ Badlands San Jacinto Valley Area Plan of the Riverside County General Plan and specifically located north of Gillman Springs Road, south of Highway 60, east of Bridge Street, and west Highway 79. Assessor's Parcel Numbers 422-240-(007, 008), 423-240-(001, 018, 019, 020, 021, 022, 023, 024), and 424-190-(001, 002).
