Peak Ranch Resource <br /> August 5, 2020 <br /> The site will be prepared to provide the best chance of vegetation establishment by completing the following <br /> as recommended by the NRCS in the Plant materials Technical Note No. 59: <br /> "The seedbed should be well settled and firm but friable enough that seed can be drilled at the <br /> recommended depth. Soils that have been compacted by traffic or other equipment should be tilled <br /> (deep-chiseled or ripped if necessary) to break up restrictive or compacted layers and then harrowed <br /> and rolled or packed to prepare the required firm seedbed. Avoid seedbed preparation when the soil <br /> is wet to prevent compaction of the seedbed. Planting depth less than 1-inch." <br /> Forest planting is not the reclamation choice for this property; however,trees will be strategically placed in <br /> order to minimize the visual impacts of the operation from adjacent properties. The general locations of tree <br /> plantings are shown on Maps C-2A, C-26, and F-1. Final locations and quantities will be field selected to <br /> maximize screening effectiveness. Table E-5 lists the trees that will be planted in the northwest and southwest <br /> corners of the site. <br /> Table E-5: Tree Plantings <br /> Species Caliper/Height Quantity(estimated) <br /> Lanceleaf Cottonwood 3-inch caliper 3-6 <br /> Quaking Aspen 3-inch caliper 2-5 <br /> Colorado Blue Spruce 5-8 feet tall 2-4 <br /> 4.0 RECLAMATION TIMING <br /> Screening berms will be seeded within 90 days of their construction using the permanent rangeland grass <br /> mixture. These berms will be irrigated for two years using either the on-site water truck or an installed on-site <br /> irrigation system. Diversions under the decreed irrigation water rights associated with the site will be used, as <br /> necessary, to provide the irrigation water supply. The southern berm will be permanent. The berms on the <br /> north and west edges will only be removed if the topsoil from those berms are needed to reclaim the Phase 2 <br /> area if the Phase 2 area is not mined to create an open water pond. If Phase 2 mining occurs,the topsoil <br /> forming the berms on the north and west edges will not be needed for reclamation and therefore these berms <br /> would remain in place on the site following reclamation. <br /> All reclamation will be completed within five years of the beginning of reclamation in a specific stage or phase <br /> and all reclamation will be complete within five years of the end of mining. Table E-6, below, summarizes the <br /> timing of reclamation throughout the life of the mine. The anticipated timing is based on a 10-15-year mine life, <br /> depending on market conditions. If the mine life is extended,the appropriate years will be added to the <br /> timeline to accommodate reclamation. <br /> Table E-6: Reclamation Timetable <br /> Years Activity <br /> 1-2± Phase 1 mining and contemporaneous reclamation within phase <br /> 2-3± Phase 1 mining and contemporaneous reclamation of slopes <br /> above Phase 2 footprint <br /> 3-13± Phase 2 mining, no required reclamation <br /> 13± Removal of all portable equipment, fuel tanks, and pumpset; <br /> reclamation of remaining disturbed areas <br /> 13-15± Revegetation monitoring <br /> O TETRA TECH <br /> crs:i.•w;�ti�a�a�ssncialo,ri i.� E-5 � <br />
