Boulders and fallen dead or felled timber (not harvested for firewood) will be arranged <br /> approximately near their original locations to give the site a natural look. All work is aimed at <br /> returning the area to look natural and undisturbed (after re-growth). <br /> As detailed in Exhibit C—Mining Plan, large dumps will be avoided and reclamation efforts will <br /> be reduced as the backfill, though rough, will be already replaced into the trenched area during <br /> actual trenching using a cut ahead and fill behind cut and fill approach. Final recontouring, <br /> topsoil replacement, raking, and seeding will be all that would remain after backfill from this <br /> type of excavation. <br /> Excavation, with concurrent backfilling, will take place first. When work is completed in a given <br /> locality, reclamation work (consisting of re-contouring, topsoil replacement, raking, and <br /> placement of felled trees and boulders), will be conducted prior to moving to the next locality. <br /> Seeding would be conducted during the fall as recommended by USFS. <br /> To re-iterate; area and volume-wise, over the life of the permit and operation, a maximum of <br /> only 2.0 acres of topsoil replacement/final recontour work and seeding and up to 1,000 yards of <br /> trench backfill work would be necessary at the close of each area or season or at the end of the <br /> permit. <br /> 6.3.4. (1) (a) <br /> All overburden will be backfilled into excavations proposed under this permit. Depths will very <br /> likely not exceed 12 or 15 feet from original surface. Excavations will be backfilled and <br /> recontoured to approximate their original surface contours and topsoil will be replaced to <br /> approximately its original depth from topsoil stockpiles once an excavation site is backfilled. <br /> Excavation of material is very limited. While some settling of backfilled materials over time is <br /> expected, no depressions will remain. Recontoured areas will be slightly bowed since <br /> excavated materials expand. Over a season or two, after being returned to the excavation site, <br /> the backfilled materials will settle somewhat and any bulging will dissipate. <br /> 6.3.4. (1) (b) <br /> The maximum gradient of backfilled and recontoured surface slopes will depend largely on the <br /> original topography of the areas disturbed. Based on USGS DEMs and topographic maps, <br /> recontoured slopes will not exceed 3:1 horizontal: vertical. In general, maximum slopes will be <br /> 4:1, horizontal: vertical or flatter. Original, pre-disturbance slope gradients will be maintained <br /> and recontouring will match existing slopes. <br /> In order to prevent undue erosion of reclaimed areas and promote seed and moisture <br /> retention, recontoured disturbance will be raked (lightly furrowed) parallel to contours. <br /> Silt fencing will be used below all excavation sites and disturbed areas which occur on slopes of <br /> 20 percent or greater(>_ 5:1 horizontal: vertical). Silt fences will be removed after 50 percent <br /> growth is established. <br /> Reclamation Permit Application for Ten Percenter Claim BLM CMC254209 <br /> USFS File Code 2810,USFS MPO-2018-004 <br />
