Mining activities in the Phase 1 azea will have, inmost cases, immediate concurrent reclamation following gravel excavation. Depressions will be filled and a more normal slope and matching topography will be established as the "clean-up" and pocket mining is completed. The applicant intends to complete the reclamation as part of the miaiag and process operations (ezeluding the 5 acre operations -stockpile area) in the Phase 1 Area as excavation operations move to the Phase 2 area. The clean-uu and minine of the Phase 1 area will assist, be part of and necessary for a reasonable reclamation of the Phase t Area due to the several soot} piles and uneven totw~ranhv left by orevious cermits. Subsequent mining phases (Phase #s 2 = 7) will be mined using scut-and-fill method where any existing overburden material will be placed into the excavated area depression created behind the advancing mine front. The general site excavation methods will place overburden materials into the base of the excavated gravel areas in compacted lifts, grade to match slope and topography and place reserved topsoil ASAP for seedbed preparation and subsequent seeding to keep surface disturbance azea under a maximum of 10 acres. The overburden and tazget aggregate thickness for Phase Areas I - 7 are as follows: Phase Area Overburden Thickness Gravel Thickness 1- 60 acres 0 to 6 feet 9 to I S feet 2 = 30 acres mostly outcrop with surface 9 [0 10 feet 3 - 30 acres mostly outcrop! l2 inches loam 9 to l0 feet 4 - 40 acres 6 to 10 feet * ** l5 to 20 feet 5 -30 acres 6 to 10 feet *** 9 to 10 feet 6 - 40 acres some outcrop, up to 6 feet 9 to 10 feet 7 - #O acres 10 to 13 feet ] 0 to I5 feet ***_ Phase Area 4 and Phase Area 5 may 6e switched ih mining order. Only 10-acres or less will be disturbed at a time in the subsequent Phase Areas #s 2-7. Reclamation will generally be concurrent with continued mining and processing operations. The limited (max 10 acres) disturbance area during the excavation operations at the site wilt provide enough room for any site excavation/reclamation, process operations and material stockpiling as the excavation front moves across and through each of Phase Area #s 2-7. Topsoil and all other useful surface material will be stripped and reserved for reclamation. Topsoil will be temporarily stockpiled in areas within each phase area which will be convenient to the concurrent reclamation activites. If topsoil stockpiles are to be left for more than 1 growing season, they will be seeded with the USDA recommended seed mix. These stockpiles will be 1_ocated out of mine traffic areas and possible temporary stockpile locations. As future mi_rting activiti_ex progress across the site from phase to phase, topsoil material will be stockpiled in a similar manner All Phase azeas will be mined as fully as possible from one area to the next leaving a uniform slope and topography and slope across Phase Area Boundaries. Spur-roads will be graded (on the original surface) into the separate phase areas as necessary from the existing site road. Spur-roads may remain at the landowners request but otherwise they will be reclaimed and seeded when no longer needed for site operations. The current site "eastside" road wilt be improved and maintained as necessary for site operation requirements. This road will remain after ail site activities have been completed. At the end of Phase 7 at the site the final 10 acre disturbance, at the Phase 7 area and Ore remaining 5 acre operations area located in the Phase i Area will be left to reclaim and that approximately l5 acres, more or less, will remain disturbed at that time. (b) Earthmoving; All topsoil material, and/or usable surface material, will be stripped and stockpiled as necessary in each phase area using bulldozers, motorgraders, scrapers and frost-end loaders. All mined materials will be excavated and handled onsite using bulldozers and front~nd loaders to feed the
