The maximum exposed area prior to reclamation would be between 3 and 4 acres. This amount of working area is needed in order to extract the r« k. While the South Peak is being mined the maximum extent of disturbance would be experienced, but as soon as that area is finished and while the mining is being completed to the north, the area of reclamation implementation would accelerate rapidly. Please keep in mind that this amendment area is quite small and highly confined, plus most of the r« k is contained in only about 1/2 of the entire amendment. This means that most of the r« k will be removed from an area which is smaller than the average city bl« k. lY~til nearly all of that area is completed it is simply impossible to implement any reclamation without endangering the reclamation itself. ITQ1 4 - You have stated that the largest portion of Phase III will be mined from south to north. Will benching «cur in a general west to east direction, an east to west direction, or a general upslope direction. RE5PWSE: Benching will not «cur immediately under the South Peak. That area will be very gently sloped to the south and southeast. Benches an the west side of the remains of the South Peak will face east to northeast and will be linearly directed along a north-south line. Benches to the north of the gently sloped area under the existing South Peak will face south and will have a general west~ast linear orientation. Bench development will follow the direction of mining. ITEM 5 - Will a bench section be mined completely across the Phase III area before pr«eeding to the next higher bench or will there be several levels of benching «curring at the same time? f~ONSE: This all depends upon the total depth of mining at a particular 1«ation. If the depth of mining is approximately equal to the planned final wall height then only one or maybe two benches would be created at a time. But if the total depth of mining is greater than the final wall height//several benches must be worked at a time in order to satisfy safety requirements. ~bwever, in those instances where several benches are worked at a time~ance the final bench pattern is created,virtually all of that area can be reclaimed at once. ITEM 6 _ If mining from the north end southward does not «cur, will the northern drainage crossing still be necessary? If so, why? RESPUV5E: hider the revised plan, where the horseshoe shaped 2.4 acres have been removed from the extreme north End of the amendment, it is unlikely that a north crossing would ever be needed. I-bwever, we wish to keep that in the plan because it is possible that equipment access to the north end of the mining area might still be needed in order to avoid crossing land under reclamation on the south end of the amendment. If that did came to pass then the south crossing would probably be abandoned and reclaimed when the north crossing is established, as there would be no need to have a south crossing.
