RECLAMATION PLAN EXHIBIT E ~®np~u~ zooz In this amendment the method of mining and reclamation remain unchanged from what is now approved, only the size of the mine will change. Grading will be such that drainage of the interior area will be toward the existing natural drainage course that is at the western mine entrance. This proposed change increases the amount of revegetation that will be done on the mine. Under the old plan only the flat benches around the mine needed to be reclaimed, and the floor area is designated as commercial area. Under the new plan this does on change on the existing mine area. what does change is that the north face will be removed and a long 3h to lv slope will be created along the north side of the new area. There will still be near vertical benches in the new area, they will only exist as an extension of the east face, around the northwest corner of the new area and along the west side of the mine. All of the mined area has been combined into Phase I to create a single mining and reclamation stage/phase. Reclamation for the existing areas of Phase I remains unchanged from the previously approved plan. The current methods and plan to reclaim the area will be used on the new area with a minor change in the tree planting scheme. In the three areas where vertical benches will be left, the west side, and along the ease and south side of the existing permit area, the overall bench slopes (horizontal to vertical) may vary between Oh:ly and l.lh:ly. The Current Conditions Map shows that existing natural slopes are, about 0.8h:1v in certain places along the south side of the property, and approximately how the site looks at this time. The operator expects the slope of the mine floor when finished, to be a very gentle, one or two percent from east to west, thereby establishing positive drain- age. On the north slope area where the newly mined slope blend 14 (Revised 8/19/02)
