• EXIT E <br />RECLAMATION PLAN <br />~ The cutbanks (highwalls) on the north end of the property <br />' (Photo I-1) will be sloped at 3:1. The topsoil, approximately 5- <br />feet deep, will be removed prior to the sloping of the cutbanks. <br />Careful handling of the topsoil will provide 1,400 yards for <br />reclamation. This topsoil will be spread about 1 to 3 inches <br />' thick over the reclaimed slopes and have 6,000 pounds of manure <br />per acre incorporated into this topsoil. The 1,400 yards of <br />topsoil will provide the necessary humus for soil moisture <br />retention and the manure will provide the nutrient base necessary <br />for seedling establishment. The 1 to 3 inches of topsoil and <br />6,000 pounds of manure will be disced. The topsoil and disced <br />' manure will provide a plant-growth medium of adequate depth and <br />ensure maximum survival of revegetated species and successful <br />reclamation efforts. <br />' This process, topsoiling with manuring, will be used <br />throughout the reclamation sequence. The only change will be the <br />stockpiling of topsoil. More topsoil will be available per acre <br />' than being used to reclaim the already existing pit area, since <br />the Stoneham soil will provide 8 to 14 inches of topsoil per acre <br />from undisturbed sites. Undisturbed acreage of Stoneham soils is <br />' about 10 acres and because only 4 to 6 inches of topsoil will be <br />placed back over the reclaimed areas, this will result in the <br />stockpiling of topsoil in some years. Stockpiles will usually be <br />less than 1-acre foot. Stockpiling is necessary to ensure ode- <br />' quote cover for areas that have been disturbed previously without <br />topsoil being saved and for those areas that are now being mined <br />and did not have topsoil stockpiled. <br />' All lands will be reclaimed to rangeland which is the <br /> existing land use. There will be limited earthmoving except the <br /> sloping of the cutbanks at the north end of the property. As <br />' photo D-1 shows there will be little earth moving as the mining <br /> sequence moves southward. <br />Area A: This portion of the mined out pit will be reclaimed <br />first. It is about 4 acres in size. The cutbanks will be graded <br />to a 3:1 (horizontal to vertical) slope in order to maintain as <br />' much of the land owners field as practical and still acquire <br />topsoil for reclamation. <br />Area 8: An area of secondary extraction, that is, it has <br />been mined once for gravel and is now being mined for sand. <br />Photo D-1 shows this area in the third panel from the le Ft. It <br />is about 0.75 acre in size. <br />' Area C: Previously mined far gravel then left unreclaimed. <br />With the extraction that will be taking place in Acea B this area <br />' will be mined for its sand as well. Reclamation will be a <br />sloping of the pit side at 3:1 to acquire topsoil then sloping <br />10:1 in the pit bottom. <br />' 6 <br /> <br />
