Tonsoilin~ <br />The top 2 to 6 inches of soil on the property is classified as topsoil. This layer includes the root <br />zone of grasses and crops, which will be stripped and stockpiled separately. By using concurrent <br />reclamation techniques, the topsoil is not expected to remain in stockpiles for more than 1 to 2 <br />years. If the stockpile remains more than one growing season, it will be seeded with a fast <br />growing vegetative cover to prevent erosion. All topsoil will be retained on-site to reclaim the <br />lake shoreline, replacement wetlands, and other areas disturbed by mining activities. Where <br />required, topsoil will be replaced to a depth of approximately 4 to 6 inches. <br />When necessary, stripped topsoil will be stockpiled parallel to potential flood flows to reduce the <br />risk of inhibiting the flow. Throughout the mining phases, the amount of topsoil stockpiled will <br />be limited by continuously using it to cap backfilled areas. <br />Reveeetation <br />As mining operations are completed, aeeas for reclamation will be graded and shaped for <br />revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes <br />being graded and seeded. If needed, berms will be constructed to divert excess water and dispose <br />of it in a safe and non-erosive manner. <br />Upland Areas. The grass mixture below was selected to be long lasting and regenerating. The <br />ground will be fine graded prior to seeding and fertilizers will be applied according to <br />recommendations from the Natural Resource Conservation Service. Based on the soils in the <br />area, the following upland seed mixture is recommended: <br /> <br />Upland Grass Seed Application Rate <br />(#PLS/acre) <br />Indian Rice rass "Nez ar" 1.48 <br />Indian Ricegrass "Rimrock" 1.48 <br />Western Wheatgrass 4.75 <br />Sideoats Gramma 0.91 <br />Blue Gramma 0.63 <br />Mountain Brome 1.94 <br />Slender Wheatgrass 1.10 <br />Pruie Junegrass 0.21 <br />Great Basin Wildr e 4.02 <br />Needle and Thread Grass 3.03 <br />Narrowleaf Indian Paintbrush 0.02 <br />Blue Flax 0.12 <br />Foothills Golden Banner 0.23 <br />TOTAL Lbs.
