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 is maximum. This point occurs during <br />the mining of Phase I1I. At this time the active mining face and interior walls of the Pond 3 <br />mining area will be at its greatest length. There will be shoreline (exterior mine area wall) under <br />reclamation in the Pond 3 mining area. Please refer to Exhibit D for a listing of disturbed areas <br />that total 31.8 acres. This estimate will follow the same order as the listing in Exhibit D. <br />Aspect <br />Reclamation Operation <br />Quantity <br />Units <br />Unit Cost <br />($1 <br />Cost ($) <br />Pond 3 <br />A <br />Slurry Wall, 10,000 LFx 30 feet deep <br />�20 <br />60,000 <br />SgFt <br />3 <br />180,0(20016) <br />B <br />Stripped Overburden and Topsoil in <br />Anticipation ofA inin <br />1.
