6.4.5 Exhibit E -Reclamation Plan <br />Description <br />All areas adjacent to oil and gas wells will be backfilled to a radial distance of <br />150ft following excavation. Reclamation will occur concurrently with mining <br />following completion of gravel extraction in the western 1/3 of Cell A. <br />Reclamation will backfill slopes to 3H:1 V in the pit and the pit will be reclaimed as <br />a water-storage reservoir. <br />All affected areas above the normal pool elevation of the reservoir will have <br />topsoil replacement and be re-vegetated with native vegetation followed by a <br />weed control program. Exhibit F- Reclamation Plan Map shows final grading and <br />topsoil/ re-vegetation areas. <br />Reclamation Earthwork <br />Reclamation earthwork will occur concurrently with mining and will begin <br />following extraction of sand and gravel from the northern 1/3 of Cell A. <br />Stockpiled overburden located adjacent to the mined out cell (--60,000 yd3) will <br />then be placed onto the slopes of the northern 1/3 of Cell A. Additional <br />overburden stripped from the remaining mine area will be directly replaced onto <br />mined out slopes as the operation proceeds. There is approximately 500,000 yd3 <br />of overburden within the pit area. Approximately 500,000 yd3 of overburden will <br />be used to backfill the slopes. Following slope backfilling, clay material will be <br />ripped from the pit floor and used to construct a compacted clay liner. About <br />34,000 yd3 of clay material located on the pit floor will be ripped, moisture <br />conditioned and placed in 1 ft thick lifts on the pit slopes. Compaction will then <br />occur for each lift and scarification between lifts will be achieved. The <br />compacted clay liner will be constructed to a thickness of 4 feet. The applicant <br />chooses to place a 100% bond for the clay liner. <br />Topsoil Replacement <br />Topsoil will be placed to a depth of 1 ft on all affected areas above the normal <br />pool elevation of the reservoir. The total area to undergo topsoil replacement is <br />10.7 acres and the total topsoil replacement volume is approximately 17,300 yd3 <br />Nelson Mining Resource <br />Regular 112 Permit Application <br />
