CEMEX Mining and Reclamation Plan Permit Amendment (ZF2018-0015)

CEMEX Mining and Reclamation Plan Permit Amendment (ZF2018-0015)

The proposed project is a request to modify an approved mining permit and reclamation plan for the existing CEMEX sand and gravel mining operation to allow more mining over a longer period of time. The operation is located primarily east of Interstate 505, along the south bank of Cache Creek, near the unincorporated community of Madison. The existing off-channel mining operation is operated subject to a 1996 permit approval, but has been operating continuously at that location since the 1970’s. The project site is 1,902 acres, with mining limited to 586 acres and reclamation required for 716 acres (including the 30-acre plant site). The current approvals allow maximum annual mining of 1,445,783 tons (1,200,000 tons sold), and maximum total mining of 32,170,000 tons (26,700,000 tons sold). Mining is allowed to occur in seven phases moving generally from west to east, over a 30-year period ending in 2027, to a maximum depth of 70 feet. The applicant is seeking approvals to increase maximum annual mining to 2,117,647 tons (1,800,000 tons sold), increase maximum total mining to 56,248,958 (48,256,687 tons sold), extend the permit period by 20 years to 2047, increase the reclamation area by 121 acres (to 837 acres) to include disturbed land along the northerly boundary of mining (adjoining the creek bank), and make other minor modifications to correct the total mining acreage and adjust phasing. These modifications, if approved, would result in changes to the approved conditions of approval and development agreement for the project.
