The north end of the mine floor would <br />have to gradually slope to the canyon. This may mean that only a <br />small part of the north side will be mined for slab rock. I have <br />revised the Reclamation Plan Map showing how this may look. <br />Water is not an issue on this land. The minor pools in the <br />bottom of the ephemeral canyon will not be disturbed. The up <br />gradient flows that replenish these pools will not be disturbed <br />by mining so nothing will change. Since no mining will take <br />place in the bottom of the canyons and only loose rock will be <br />removed then the carrying capacity should actually be increased. <br />I also think that any precipitation water that collects in the <br />mined area could provide a source of water for wildlife and stock <br />that does not exist now. <br />(d) See the typical sketch for the location of the topsoil <br />piles. Considering the general plan for "reclaiming as we <br />go", there will be a minimal "pushing" distance, resulting <br />in a modest bond cost. <br />(e) This timetable would only apply for the final five years of <br />the mining operation. Since reclamation has to run concur- <br />rent with mining, for mining to be able to progress, all but <br />20 acres of the total mine would be reclaimed or undis- <br />turbed. The numbers used in Exhibit L better reflect the <br />amount of work necessary if mining ceased or when mining <br />ended. The timetable below is for a typical 20 acres of <br />disturbance. The total slope length exceeds the perimeter <br />length because the working face would also have to be <br />sloped. <br /> ACRES t LINEAR FEET <br />PHASE YEARS TOTAL <br />AREA REVEGETATI <br />ON NEEDED REBOILING ROAD SLOPING <br />COMPLETE SLOPING <br />NEEDED <br />SLAB 3-5 15.00 15.00 10.80 0.0 1,143 2,468 <br />SURFACE 3-5 5.00 5.00 NA 0.0 NA NA <br />(f)(ii) The following seed mix and rates are the same as for <br />the Pinon Mine with Little Bluestem added.
