RECEIVED <br />SEP 13 ZOOb <br />EXHIBIT L Division of Reclamation, RECLAMATION COSTS <br />Mining and Safety <br />This reclamation cost estimate in based on the assumption that <br />the entire site will need some form of reclamation any one time. This <br />is the worse case scenario i.e., at a time when the greatest area will <br />need some form of reclamation. At that time we will have to respread <br />11,688 cubic yards of topsoil, shape 33.72 acres of floor area and <br />revegetate 7.12 ac. ±. The table below outlines the various areas of <br />disturbance at that time. The amount of topsoil that will be re- <br />spread is based on an average of 4 inches. A 631-D motor scraper will <br />be used to resoil the area and a 140G motor grader will be used to <br />shape the seed bed and mine floor. We have included the cost to <br />reduce the highwall using a D-BN dozer from near vertical to 2:1 if <br />mining ends prematurely. These figures are then used in the calcula- <br />tion for the bond amount. The revegetation cost figure includes <br />fertilizer, grass seed, mulch and drilling costs. <br />STAGE TOTAL SOIL DEPTH <br />NEEDS REBOILING 7.21 AC 4" <br />NEEDS SEEDING 7.21 AC <br />GRADING FLOOR 33.72 AC <br />REBOIL @ 4" 4,269 CY <br />CUT/FILL (29.62 cY/nFx> 12,444 CY <br />Secondary revegetation 25°s <br />ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: <br />Unit Cost <br />1.
