' VIII. EYHIB[T L - RECLAiV[ATION COSTS <br />' As described in Exhibit E -Reclamation Plan. and as shown on Figures F-1 and F-2. <br />Reclamation Plan Maps. the proposed reclamation will consist of either an open water lake or <br />a water reservoir. Both conditions will include a reclaimed shoreline seeded with native <br />grasses as shown on Figures F-l and F-2. Along the Cache La Poudre River, trees and shrubs <br />' will also be planted with two inch caliper cottonwood trees planted randomly to appear <br />natural, but on average on d0-ft centers. Because of the open water reclamation of the <br />majority of the acreage within the site, most of the site will not be seeded, but wilt be <br />' submerged. The following assumptions were made to develop the reclamation cost table, <br />Table L-l, presented below: <br />^ The total site area is 69.89 acres, of which a maximum of 50.34 acres will be disturbed <br />1 if the Ogilvy Ditch remains in-place, or a minimum of X9.91 acres will be disturbed if <br />the Ogilvy Ditch is relocated. Total acreages of 14.5 and 19.98 would constitute <br />undisturbed training area perimeter (setbacks and minimum Cache La Poudre River <br />' buffer zone) for in-place and relocation scenarios, respectively. <br />' ^ Overburden backfill will be at 3:1 (H:V). Topsoil will be placed and slopes reseeded <br />and fertilized, and also mulched, above lake pool elevation. <br />' ^ No reseeding will be performed on the lake bouom or other submerged areas that are <br />expected to consist of low permeability claystone bedrock or permanently submerged 3:1 <br />' backfill slopes, respectively. <br />' ^ Reclamation will be concurrent with mining. Reclamation earthwork costs assume that <br />at any given time during peak mining activities that a maximum approximately 35-acre <br />' phase is mined out requiring regrading and seeding of a maximum of one-half of its <br />perimeter. At the same time. the adjacent approximately l5-acre phase is assumed to be <br />stripped of topsoil requiring only regrading, topsoiling and seeding. <br />^ All mining will be done with portable eyuipmen[ and field conveyors that, if left <br />' abandoned, would be reclaimable at no cost ro DMG based on the salvage value. <br />^ The Rzady Mixed plan[ will also he portable and, if left abandoned, would be <br />' reclaunable at no cost to DMG based on the salvage value. <br /> <br />i8^7~iiiiii ' b <br />
