Santa Margarita Quarry Expansion Project / Conditional Use Permit and Reclamation Plan Amendment

Santa Margarita Quarry Expansion Project / Conditional Use Permit and Reclamation Plan Amendment

FYI Final The Applicant proposes to expand the existing boundaries of the quarry by an estimated 33 acres, thereby enlarging the "footprint" of the quarry from 160.1 acres to 193.1 acres. The proposed expansion would yield approximately 21.5 million tons of aggregate reserves. These reserves, in combination with existing entitled reserves, would result in the quarry producing 33.2 million tons of aggregate products over a 59-year period. Proposed reclamation activities would be initiated in those areas of the quarry that have been depleted of resources in a manner concurrent to ongoing mining operations. All proposed reclamation activities would be fully completed within 5 year of resource depletion (e.g., five years after mining activities have stopped). Lands within the quarry would be reclaimed to open space uses, including seasonal water storage, riparian habitat, oak woodland habitat, and chaparral vegetation. Based upon the above, the proposed project is defined as all mining operations associated with the proposed 33-acre expansion area and reclamation of the entire quarry site, as expanded. The full 193.1-acre site is referred to as either the Proposed Project area, or Proposed RPA area. No changes to the quarry's existing annual production volumes or intensity are proposed beyond what is currently permitted.
