Processing Area). <br /> -Reclamation of North Silt Pond(currently being proposed) <br /> -Reclamation of Perimeter Disturbed Areas(outside of cells) <br /> -Backfill and Reclamation of Mined Areas(80%since mining sides will be at 3:1 reclamation slope). <br /> -Slurry Wall Repair(50%rebuild) <br /> We appreciate your review.
