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 its maximum. This point occurs during the
mining of the cell 4. Here the dewatering ditch will be at its maximum length along with roads to
the processing azea. Please refer to page 5 for a listing of disturbed azeas that total 34 acres. This
estimate will follow the same order as the listing on page 5.
