EXHIBIT L <br />RECLAMATION COSTS <br />This reclamation cost estimate in based on the assumption that <br />there will be no more that 34.97 acres ± disturbed at any one time. <br />The following information also depicts a worse case scenario. At that <br />time we will have to respread 6,623 cubic yards of topsoil, do 800 <br />cubic yards of cut/fill dozer work, and revegetate 34.97 ac. ±. The <br />table below outlines the various areas of disturbance at that time. <br />The amount of topsoil that will be re-spread is based on an average of <br />4 inches. A D-8U Catepillar dozer will be used to do all of the <br />cut/fill work. A Catepillar 140H blade to rip and shape the seed bed <br />and a Catepillar 627E to resoil the site. These figures are then used <br />in the calculations for the bond amount. The revegetation cost figure <br />includes fertilizer, grass seed, mulch and drilling costs. <br />STAGE TOTAL SOIL DEPTH <br />NEEDS RESOILING 34.97 1.5" <br />NEEDS SEEDING 34.97 <br />GRADING & SHAPING 34.97 <br />RIPPING SHALE 34.97 <br />SLOPE CUT/FILL 800 LINEAR FEET <br />RESOIL @ 1.5"11 6,623 CUBIC YARDS <br />ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: <br />1 <br />2 <br />3 <br />4 <br />5 <br />Revegetation includes grass seed mix, fertilizer <br />and labor to drill . . . . . . . . . . . . . <br />Re-spreading soil with a, 627E scraper, haul distance <br />less than 700 . . . . . . . . . . <br />Sloping using cut/fill method <br />D-8U cat, push distance less than 90 <br />Ripping shale surface using 140G <br />Grading and shaping seedbed using <br />140G motor grader . . . . . . . . <br />RECLAMATION COSTS <br />1.
