• • MINING PLAN <br />topsoil. These stockpiles will be removed as land becomes available for reclamation to the south of <br />the active mining in Phase I. As subsequent cuts are made these stockpiles may be added to. Or, if <br />preferred and mined out land is available, subsequent stripping of subsoil and overburden may <br />simply be hauled to the final location and used for backfill. This process avoids the need to store <br />material and avoids double handling expenses. <br />Mining Processes: Mining of Phase 1 will be done in a fashion similar to a classic <br />coal strip mine. An initial cut is made at one end of the mining area (the southern end, in this case). <br />When that is mined out, subsequent cuts are made adjacent to the previous cut. The conveyor and <br />dewatering facilities are moved to serve the new cut. Overburden from the new cut can be simpl}' <br />hauled to the mined out portion of the previous cut and placed in accordance with the reclamation <br />plan. Final shaping of the backfilled area need not be done until a reasonable amount of backfilling <br />has been completed. Because of the shape and size of this site, it is unlikely that any final shaping of <br />backfilled land will occur until the mining has proceeded to about the middle of Phase 1. That <br />condition is shown on Exhibit C-2B. At this point, final shaping of the south end of the lake area <br />can be done. <br />The important point in this mining and reclamation sequence in Phase 1 is that reclamation <br />is occurring in the mined out portions of the pit while mining is occurring in other portions of the <br />pit. This avoids the problems of having to reclaim the entire area all at once when all the mining is <br />completed. This procedure is especially important for Phase 1 because of the configuration of the <br />final lake in Phase 1. More detail on this aspect is presented in Exhibit E -Reclamation Plan, but in <br />general, the shape and extent of the backfill in Phase 1 will probably be greater than the available <br />material. That is, to complete the designed lake configuration in Phase 1, some overburden and soil <br />ma}' need to be borrowed from Phase 2. This borrowing process has been accounted for in the <br />design of the operation. The lake configuration in Phase 2 is not so critical as it is in Phase 1 and <br />therefore deficiencies of backfill in Phase 2 will not have such a significant impact on the final <br />condition as they would have in Phase 1. <br />PHASE 2: <br />Initiation of Phase 2: Phase 2 does not need to wait until the full completion of <br />Phase 1 to begin. In fact, that is probably not desirable from a mining or reclamation point of view. <br />As noted in the previous section on Phase I, it is possible that some overburden and subsoil from <br />Phase 2 will be needed to complete the backfilling of Phase 1. Because the exact amounts of backfill <br />needed and available in Phase 1 are not precisely known, it cannot be determined beforehand <br />Grisenti Farms Gravel Pit Original Application Exhibit D Page D-6 <br />
