Revised Exhibit L, Reclamation Cost Estimate
In order to calculate maximum potential reclamation liability to the State, we have selected a point in
time where the mining disturbance could be at is maximum. This point occurs during the mining of
Phase II. At this time the mining face in the east/west direction will be at its greatest length. There will
be shoreline under reclamation in the Phase II area. The Phase I pit will be in use as a siltation pond and
the collected silt will be lefr in place as backfill. Please refer to page 5 for a listing of disturbed areas
that to[a145.4 acres. This estimate will follow the same order as the listing on page 6:
