• • EXHIBIT L RECLAMATION COSTS This reclamation cost estimate in based on the assumption that there will be no more that 13.00 acres ± disturbed at any one time. The following information also depicts a worse case scenario. At that time we will have to respread 18,279.07 cubic yards of topsoil on 11 .30 acres, shape 9 .43 acres prior to resoiling and revegetate 13 .00 ac. ±. The amount of topsoil that will be re-spread is based on an average of 12 inches. A 631D motor scraper will be used to do all of the topsoiling work and a D-9 dozer will be used to shape the area. These figures are then used in the calculations for the bond amount. The revegetation cost figure includes fertilizer, grass seed, mulch and drilling costs.
