<br />RECLAMATION COSTS <br />EXHIBIT L <br />This reclamation cost estimate in based on the assumption that <br />there will be no more that 35.00 acres ± disturbed at any one time. <br />It is also based on a worse case scenario i.e., at a time when the <br />greatest area will need some form of reclamation. At that time we <br />will have to respread 20,166 cubic yards of topsoil, do 5,400 cubic <br />yards of cut/fill dozer work on the working face, prepare 35 acres of <br />seedbed and revegetate 35.00 ac. t. The table below outlines the <br />various areas of disturbance at that time. The amount of topsoil that <br />will be re-spread is based on an average of 6 inches and the cut/fill <br />volume per linear foot is 2.00 cy/lf. In this estimate a D-8 dozer <br />will be used to do the cut/fill sloping. A 631-D motor scraper will <br />be used to resoil the area and a 140G motor grader will be sued to <br />shape the seed beds. These figures are then used in the calculations <br />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 25.00 6" <br />NEEDS SEEDING 35.00 <br />SEED BED PREPARATION 35.00 <br />SECONDARY RESEEDING 25$ <br />SLOPE CUT/FILL 2700 LINEAR FEET <br />REBOIL @ 6" 20,166 CUBIC YARDS <br />EST/MATED UN/T COSTS FOR RECLAMAT/ON /TEMS: <br />Unit Cost <br />1.
