measures will be taken to prevent the material from moving downslope (e.g., silt <br /> fences). <br /> Upon replacing the overburden and reclamation of the dig site,the compacted soil <br /> where overburden stockpiles were placed will be raked with the backhoe bucket to <br /> break up the soil and provide small furrows for trapping and holding water, seeds, <br /> and nutrients for plant growth. If needed we will also hand-rake areas that need <br /> further de-compaction. <br /> Regolith and substratum will be piled adjacent but separated from the topsoil. When <br /> the excavation is reclaimed, the substratum and rock will be placed first into the <br /> excavation, followed by the topsoil. The soil will be distributed evenly to a maximum <br /> depth allowed by the amount of soil initially present. The site will be re-contoured <br /> to match the original contour except where prudent to terrace the surface to <br /> prevent erosion and to hold the soil. Silt fences or deadfall from the Hayman fire <br /> may also be used on steeper slopes and will remain in place until vegetation is <br /> reestablished. See Exhibit E-map (Detail — 1) for approximate stockpile locations. <br /> 6.3.3 (1) (d) <br /> The thickness of the deposits to be mined will vary depending on the depth of the <br /> pegmatite lode. The maximum depth will not exceed 20 feet from a safely benched <br /> surface area. <br /> 6.3.3 (1) (e) <br /> Three dig sites are specified in this permit (see Exhibit A, location map, Detail-1) for <br /> precise locations). However, dig sites A and B are in close proximity to one another <br /> and may eventually join depending on the size and direction of the pegmatites. The <br /> main roads and access route to the Redemption 2 & 3 mines is specified in the maps <br /> of Exhibits A& E. No new roads will be created to access the mine sites.All vehicles <br /> and equipment (a small backhoe or excavator) will be "walked in" from the main <br /> access road (Forest Service Road 274) to the mining sites using the temporary roads <br /> labeled "temporary access routes" in Exhibit A Map - Detail 1. These temporary <br /> roads will be approximately 12 feet in width. Only dead trees up to a width of 10 <br /> inches will be removed along the routes. The grade on these routes is no more than <br /> a 5:1 ratio.As such, no significant grade changes or culverts are anticipated. Only <br /> personal vehicles and excavation equipment will be used along these routes.All <br /> routes will be graded to their original grade if changed and will be reclaimed with a <br /> blend of native grass seed approved by the U.S. Forest service. <br /> No on site processing facilities or structures will be constructed.All processing of <br /> the mineral specimens will take place off-site. No underground ventilation is <br /> required as the dig sites will be open pits. <br /> 6.3.3 (1) (fj <br /> The total mining disturbance will not exceed 2.22 acres with a maximum of 1 acre <br /> affected at any one time (excluding the temporary access routes), with no more than <br />
