RSCLA!lATION COSTS (rev~d 9/91) <br />III IIIIIIIIIIIIIIII i <br />BxBIBIT L <br />Reclamation costs are estimated assuming that the greatest area of <br />disturbance will exist when 608 of Stage A is reclaimed and 758 of Stage <br />B is partially mined and all stripped. Included in the calculation is <br />the cost to slope the highwall that will cross Stage B. The table below <br />outlines the various areas of disturbance in each stage and the amount <br />of topsoil that will be spread in each stage. These figures are then <br />used in the calculations for the bond amount. <br />STAGE A B P TOTALS SOIL DEPTH <br />NEEDS REBOILING, <br />FERTILIZER & MULCH 15.74 36.08 13.41 65.23 <br />DRYLAND SEEDING 3.17 7.70 0.00 10.87 6.0" <br />IRRIGATED SEEDING 12.57 28.38 13.41 54.36 10.0" <br />ROAD 0.48 0.00 1.16 1.64 <br />GRADING/SHAPING 15.74 36.08 13.41 65.23 <br />UNMINED 0.00 9.02 13.41 22.43 <br />REVEGETATION CMPLT 23 60 0 00 0 00 23.60 <br />STAGE TOTAL 39.34 36.08 14.54 89.96 <br />CUT/FILL HIGHWALL <br />SLOPES @ 6" <br />FLAT AREAS @ 10" <br />TOTAL <br />32.41 CY/LF <br />8,770 CY <br />73,085 CY <br />81, 855 CY <br />F.RTTMATF.D ('ORTS FOR RF.('i.AMATTON TTF.MS AR F.
