Mav '2 2 <br /> 2.12.8 Implementation of the Reclamation Plan <br /> 2.12.8.1 Topsoil Segregation, Preservation, and Replacement <br /> The topsoil and overburden excavated, stockpiled an/ or used for berm construction during <br /> Phase 1 will be used to support the revegetation of the site. <br /> Backfilling and recontouring of the excavation area will not occur; the 12.56-acre pond filling <br /> the excavation pit will be left in place after the mining and extraction activities finish. Areas <br /> outside the boundaries of the pond, including the Operation Pad, will resurfaced with <br /> overburden and topsoil. This will be placed with a bulldozer and haul trucks. A roller will be <br /> used for compaction and sloping. Recontouring to a rough texture will support the <br /> establishment of broadcasted seeds and moisture retention. Stored topsoil and growth <br /> medium will be replaced evenly to a depth of 4-6 inches unless site conditions preclude this <br /> depth. Topsoil will also be left very rough. Soils will not be worked when wet to avoid mixing, <br /> loss of topsoil, and potential erosion issues. <br /> 2.12.8.2 Final Grading <br /> Final grading of the site is depicted on the Reclamation Map(Figure 6). This figure shows the <br /> anticipated maximum slope gradient range for reclamation. <br /> The pond created by the mining activity is proposed to remain as a permanent feature of the <br /> site. The Last Chance Ditch tailwater channel will continue to discharge agricultural return <br /> flows into the pond. There are no other existing ephemeral draws and washes that pass <br /> through the mine area. <br /> 2.12.8.3 Seeding <br /> Figure 7 includes the proposed seed mixes for the upland and wetland reclamation areas, as <br /> well as estimates of the revegetation area by type. <br /> 2.12.8.4 Temporary Seed Mix <br /> A temporary seed mix is not proposed at this time. Construction is proposed to begin in <br /> summer of 2022, and the permanent reclamation seeding would be applied in the fall. <br /> Temporary seed mixes may be considered if the site needs additional stabilization, but the <br /> completion of reclamation in concert with mining operations should obviate the need for this <br /> measure. <br /> 2.12.8.5 Long-Term/Permanent Seed Mix <br /> Seeding should occur in the late fall to avoid seeds from germinating in the summer or early <br /> fall, and then either desiccating or freezing. Figure 7 provides detailed information regarding <br /> the various types of seed mixes proposed including form (shrub, bunch, sod, etc.) and <br /> application rate. <br /> Seeding application is expected to be by drilling exclusively. Broadcast seeding may be <br /> employed in areas where drill seeding is not possible (due to steep slopes or constrained <br /> access). The wetland reclamation areas will also include hand-planting for the woody <br /> vegetation. <br /> 2-24 <br />
