planted to introduce organic material into the developing topsoil. When virgin areas are mined, all <br /> topsoil will be stripped and either immediately replaced on the previous cuts in reclamation or <br /> will be stored in topsoil stockpiles that will be immediately stabilized with vegetation and will <br /> later be used in reclamation of the site. <br /> Since the plant area cannot be reclaimed until the end of the mine's life, the silty material for this <br /> area will be stockpiled as shown on Map C-2. This area is approximately 10 acres,therefore, <br /> 4,000 CY of silt will be stockpiled for final reclamation of the plant area. All fines piles will be <br /> constructed to 2.5H:1 V slopes and will be seeded and mulched if they are to be in place over 180 <br /> days. <br /> 710,056.6 CY of overburden will be available for use during reclamation from unmined areas. <br /> This material will be generated during regular mining of placer material,with some portion of <br /> the gravel used or sold as secondary product. However, the majority is likely to be used as <br /> backfill. See Map F-1 for the planned final contour. <br /> Roughly 14 acres of the pre-law disturbance that was part of the 110 gravel operation is graded, <br /> topsoiled, and seeded. The spreading of fines will occur at a thickness of 3" over the pre-law <br /> areas. Grading of post-law areas will occur concurrently with mining. Topsoiling and seeding of <br /> future mining post-law areas will occur over 65.5 acres at a depth of 4.5 inches. <br /> At the end of the mining life, the following equipment will be dismantled and hauled off site: <br /> • all fuel tanks <br /> • piping,portable conveyors,pumps, etc. <br /> • camp trailers <br /> • portable plants <br /> • pump house <br /> Internal roads will be left in place throughout the property to be used post reclamation. Electric <br /> power poles will remain for post-mining land use. The smoothing of the final cut lake,the <br /> various ponds, and the processing area will then take place. All remaining disturbed areas will be <br /> Alma Placer Mine <br /> December 2017 E-2 <br />
