<br />EXHIBIT D <br />Reclamation Plan <br />The ultimate goal of C.O.M. Inc.'s reclamation plan is to return the land sur- <br />face affected by this milling operation to a forest environment that will have an <br />enhanced suitability for wildlife habitation. This plan will be centered around <br />the reclamation of the mine dumps and the tailings impoundment area. <br />The exposure of these sulfides to the atmosphere and to surface water during <br />the last 113 years has resulted in their weathering, oxidation, leaching, and <br />erosion. The separation and removal of the ore bearing vein and rte accom- <br />panyingsulfides will greatly seduce the degradation of the environment that <br />occurs when this material is left exposed on the surface of the land. <br />Because of their composition, acidic nature, and steep slope gradients, topsoil <br />has not developed on these mine dumps. The lack of topsoil on these mine <br />dumps obviates the requirement for removing, segregating, and stockpiling <br />topsoil from these portions of the permit area. <br />Reclamation and the future use of the land affected by this milling operation <br />were considerations in the final site selected for tailings disposition, and in the <br />design of the tailings retention structure. Land reclamation will concentrate on <br />maintaining the structural stability of the tailings dam, protecting the em- <br />bankment from erosion, and establishing the growth of a permanent cover of <br />indigenous vegetation on the tailings impoundment area. The plan for <br />reclaiming these dumps. <br />'Hess Ski b~ <br />Lodgepole Pine Common Juniper <br />Limber Pine KinnikinniCk <br />Ponderosa Pine Myrtle Blueberry <br />Engehnann Spruce Native Rose <br />Blue Spruce Bitterbrush <br />Between 20 and 30 trees ranging from 3 to 6 feet in height will be planted every <br />15 feet in a row along the outer edge of the permit area. Approffimately 30 <br />shrubs will be planted between the trees. In the event that more than one <br />species of tree ie selected For transplanting, the trees will be planted in pure <br />stands. <br />The area selected for the tailings dam has a elope gradient that varies between <br />16 percent on the northeastern edge of the site and 14 percent on the eouth- <br />western edge. When the tailings impoundment structure has reached its <br />storage capacity, the outer face of the embankment will have a elope gradient <br />of 35 percent (see Map A). <br />
