MINING PLAN Phase I Area 8 and 9 will be stripped, and Areas 8, 9, 10 and part of 11 will be mined (mostly that part of Area 11 which was already stripped prior to 1977). The topsoil from the lower area will be removed first and stockpiled in Area A (Marked TS on some maps). The topsoil will be preserved and vegetated with annual rye and Indian ricegrass. The sandstone over- burden will be drilled and shot. It will then be stripped and piled in front of Area A. Limestone will be removed from areas 8, 9 and 10 and W 1/4 of area 11. This phase was expected to require 2 years but has lasted from 1977 to 1998 and is now expected to Last for another year. The total area worked will be approximately 43 acres. Phase 1[ Areas 4 and 5 will be stripped and mined. The topsoil will be removed, stockpiled, preserved and vegetated in area A or used immediately in reclamation. The sandstone and overburden material will be stripped and piled in front of A, or placed in area D, or placed in areas which have been mined out as backfill to facilitate concuttent reclamation. At present market conditions, this phase will last for 5 years. The area worked at this time will be approximately 16 acres. Phase III Areas 1, 2 and 3 will be stripped and mined. The topsoil will be removed, stockpiled, preserved and vegetated in area A or used immediately in areas that are being reclaimed.. The sandstone and overburden material will be stripped and piled in front of A, or placed in area D, or used immediately as backfill for reclamation. This phase is expected to last approximately 5 years at current market conditions. The area worked at this time will be approximately 15 acres. Concurrent reclamation will continue during this phase. The sandstone overburden will be backfilled into the excavation left by extraction of the limestone, leveled and contoured. The topsoil from area A will be spread over the EXHIBIT D.
