<br />Ftti 1 0 [UUl EXHIBIT L <br />RECLAMATION COSTS oivisionofReraamation, <br />Mining and Safety <br />This reclamation cost estimate in based on the assumption <br />that there will be no more that 20.00 acres ± disturbed at any <br />one time. The following information also depicts a worse case <br />scenario. At that time we will have to respread 16,133.33 cubic <br />yards of topsoil, do 1,085 cubic yards of cut/fill dozer work, <br />and revegetate 20.00 ac. ±. The table below outlines the various <br />areas of disturbance at that time. The amount of topsoil that <br />will be re-spread is based on an average of 6 inches. A D-8N <br />dozer will be used to do all of the dirt work. These figures are <br />then used in the calculations for the bond amount. The <br />revegetation cost figure includes fertilizer, grass seed, mulch <br />and drilling costs. <br />STAGE TOTAL SOIL DEPTH <br />NEEDS REBOILING 18.75 4" <br />NEEDS SEEDING 20.00 <br />RIPPING SHALE 13.88 <br />SLOPE CUT/FILL 840 LINEAR FEET <br />REBOIL @ 4" 10,833.33 CUBIC YARDS <br />ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: <br />Unit Cost <br />1.
