D EXHIBIT 1 -6, RECLAMATION PLAN <br /> 1 . Top soil to be replaced as benches are made, up to <br /> two inches deep, and sown, ('see u.nder .:(d•) , method) . <br /> 2 . The limestone formation to be mined is mostly in a solid <br /> block with very tight seams, and thus can sustain a steep <br /> slope. Benches are proposed to be five feet wide with a <br /> 45° slope to the next bench. Each slope of each benched <br /> area is proposed to be 20 feet high. Soil and mulch cover <br /> on all reclaimed areas that are flat of gentle in slope <br /> would be up to six inches deep, which is consistent with <br /> the present cover. Many of the present slopes are steeper <br /> than the 45° slopes proposed in the mining plan. Each <br /> phase of plan would follow the five-year plan of Rule 6. <br /> Mining would begin from the top elevations down, and from <br /> north to south. <br /> 3 . Measures taken to revegetate: <br /> (a) Plant growth medium to be 2 to 6 inches deep, which <br /> is ". . .at least equal in extent of cover to the <br /> natural vegetation of the surrounding area. " Seeding <br /> to be consistent with Rule 6. 5 ( 1 ) . <br /> (b) Seed will be plowed and/or raked as areas become avail- <br /> able for revegetation. Fertilizer not needed. <br /> (c) Revegetation will be done in stages as benches are <br /> made. Native grasses and shrubs and trees will natural- <br /> ly invade the areas where topsoil is reapplied. <br /> Following is a list of the native species: <br /> Grasses: "The primary grasses are Mountain Muhly <br /> (Muhlenbergia montana) , Needleandthread <br /> ( Sti a comata and S. vivipara) ,and Arizona <br /> Fescue (Festuca arizonica) . Forbs are <br /> strongly dominated by Kinnikinick along with <br /> other 'wildflowers ' including Indian Paint- <br /> brush (Castillegia sp. ) , Wild Rose (Rosa <br /> woodsii ) , Fringed Sage (Artemisia fri ida) , <br /> Harebell (Campanula rotundifolia ) . <br /> Shrubs : The primary shrubs are Mountain Mahogany <br /> (Cercocarpus montanus ) , Cinquefoil (Potentilla <br /> fruticosa ) , and Tamarix Juniper (Juniperus <br /> sabina tamariscifolia) . <br /> 6 <br />
