Rifle '�r�vel Pit #1 <br /> The plan and general schedule for when and how reclamation will occur throughout the <br /> mining phases is provided on Exhibit E1, Figure 14 and Exhibit E2, Figure 15 including <br /> the periods of time (phases and stages), size and locations, and sequence for reclamation. <br /> These exhibits also depict the final grading, seeding, fertilization (none), revegetation and <br /> topsoiling. <br /> 6.3.1 Topsoil Segregation, Preservation, and Replacement <br /> The topsoil excavated, stockpiled and or used for berm construction during Phase 1 will be <br /> used to support the revegetation of the site. <br /> Backfilling and recontouring of the site will occur after the mining and extraction activities <br /> finish. Pit slopes will generally be backfilled with subsoils, overburden, and unmined <br /> materials. This will be placed with a bulldozer and haul trucks. Then the use for a roller for <br /> compaction and sloping will be tracked in. Recontouring to a rough texture will support the <br /> establishment of broadcasted seeds and moisture retention. <br /> Stored topsoil and growth medium will be replaced evenly to a depth of 4-6 inches unless <br /> site conditions preclude this depth. Topsoil will also be left very rough. Soils will not be <br /> worked when wet to avoid mixing, loss of topsoil, and potential erosion issues. <br /> See Section 6.1.1.5 for more information. <br /> 6.3.2 Final Grading <br /> Final grading of the site is depicted in Exhibit E1, Figure 16. This figure shows the <br /> anticipated maximum slope gradient range for reclamation as depicted in the Typical <br /> Section. The site will need to take on fill dirt for a source of a disposal area for clean dirt and <br /> to fill part of the pit, minimizing the size of the pond and reducing evaporation potential. <br /> The creation of a pond is planned for the site. Existing ephemeral draws and washes <br /> passing through the mine area will be reestablished or allowed to continue conveyance of <br /> ephemeral flows through the site. <br /> 6.3.3 Seeding <br /> There are different types of seed mixes to support temporary and permanent stabilization <br /> and reclamation of the site. Exhibit E2, Figure 16 provides specific information regarding <br /> the reclamation plans, final reclaimed pit pond footprint, typical section of the reclaimed pit, <br /> estimate of revegetation areas, including the types of vegetation. <br /> 6.3.3.1 Temporary Seed Mix <br /> Final seeding is best done in the late fall; therefore, if construction occurs in the summer, it <br /> may be desirable to apply a temporary seed mix to the area to help minimize erosion and <br /> provide some site stabilization. Temporary seed mixes are relatively inexpensive, and the <br /> large seeds germinate quickly. Exhibit E2, Figure 16 provides detailed information <br /> regarding the various types of seed mixes proposed including form and application rate. <br /> 34 <br />
