Oro Grande Quarries
AN AMENDED MINING RECLAMATION PLAN FOR CALPORTLAND COMPANY’S PLANNED EXPANSION OF THE ORO GRANDE QUARRIES. The Amended Plan will add approximately 315 acres to be disturbed including an additional 15 acres for Superior Quarry and minus 67 acres for removal of the cement kiln dust (CKD) dump/landfill for a total disturbed area of approximately 1,165 acres. (CKD is a by-product from the cement kilns typically captured with baghouses and mostly recycled.) Buffer areas around the quarries and overburden stockpiles, miscellaneous uses, and islands of on-developed lands within the reclamation boundary where some disturbance could occur, consists of approximately 487 acres. The overall Reclamation Plan area totals approximately 1,652 acres. The permitted Superior Quarry Reclamation Plan is on a total area of approximately 40 acres. CalPortland is currently proposing to re-open the mine and limit future mining to an approximate 14.5-acre area.
