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 />
