What is included in the expansion plan?
The proposed amendment to the Permanente Quarry reclamation plan, on file with the County of Santa Clara, would reconfigure the mining and materials storage areas through grading activities that would include cutting benches in the bedrock, backfilling excavations with mining overburden material, and re-vegetation of the final slopes created by this process. An area on the west side of the pit from which minerals are extracted is a stockpile area that receives overburden from the pit. This stockpile is required under the existing reclamation plan to be re-vegetated and to provide for proper drainage and erosion control. The proposed amendment would include disturbed areas that are currently outside the reclamation plan boundary, but which are used regularly as part of mining activities.
