<br />Reclamation Cost Estimate <br /> <br />Revised Exhibit L <br />In order to calculate maximum potential reclamation liability to the State, we have selected a <br />point in time where the mining disturbance could be at its maximum. This point occurs during <br />the mining of Phase 6. At this time the interior mining face will be at its greatest length. There <br />will be shoreline (exterior wall) under reclamation in Phases 1 through 5. Please refer to <br />Exhibit D for a listing of disturbed areas that total 40.0 acres. This estimate will follow the same <br />order as the listing in Exhibit D. <br /> Unit Cost Cost <br />As ect Reclamation O eration uantit Units $ $ <br />A.
