EXHIBIT L <br /> Reclamation Cost Estimate <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 l through 5. Please refer to Exhibit <br /> D for a listing of disturbed areas that total 34.8 acres. This estimate will follow the same order as <br /> the listing in Exhibit D. <br /> Unit Cost Cost <br /> Aspect Reclamation Operation Quantity Units $ $ <br /> A.
