General Direction of Mining
Mining Plan assumes that Charter Oak Ranch Road remains in place
for public access.
Mining to proceed from initial excavation outward to the permit
boundaries and southward until material runs out at the valley edge
below the southern slopes.
Final sloping (see Reclamation Plan) will be implemented as side areas
of the pit are mined out and no longer needed for access.
Access will be from Charter Oak Ranch Road. Its location may vary
from time to time depending on what is easiest for extraction
processes.
Best Management Practices will be used to limit discharge of
sediment on to adjacent land to the south during mining.
