ExN181T E RECLAMATION PLAN (CONT) „~~ nnaxc zooz Amendment # 5 - NORTN SLOPE AREA The new north slope area will be reclaimed using the methods of resoiling and reseeding currently approved. This will be a predominately south facing slope so the methods described in the original application for that type of slope will be used. Only the number of trees planted is changed. In the existing plan for south facing areas the plan calls for Rocky Mountain Juniper to be planted 20 to 40 feet apart to help screen the vertical faces. This is practical on mine benches but on large open areas it is cost prohibitive and would create an unnatural looking picket fence appearance on the reclaimed area. The change only affects the 3h to lv slopes on the north side on the mine. The proposed change for this slope area involves planting groups of 5 to 10 Rocky Mountain Juniper trees in scattered clumps on the slope, in an attempt to match the natural conditions. This will be incor- porated into the concurrent reclamation as mining progresses across the mine. As noted in the mining platt, filling of the benches created in this area will leave a slope that is 3h to lv and will match the upper parts of the mountain above the site. The cross sections on Figure D-1, page 11 shows how the benches would look during mining. The cross hatched area is the fill that will be placed to create a uniform 3h to lv slope. if at any time there is not enough fill to create the slope, mining will switch so no benches are mined and the slope will be mined 3h to 1 to match what is shown on the map. Once mining ends on a section of north slope backfilling will begin. No more that 1000 feet of open face mine/benches will be open on this side of the mine. Since mining will prog- ress from west to east in this area, the western 500 feet will be undergoing reclamation as the eastern 500 feet is being mined and 17 (Revised 8/19/02)
