<br />deer and elk range. We leave seen an occasional deer but no elk on the site for over ten <br />years since the animals were fed by DOW on the flat top of the ridge immediately north <br />of the pit. Little feed exists on the leased area. Plentifiil grass exists on meadows <br />mentioned to the north and west and leave been purchased by the state DOW for critical <br />range. This purchase fiirther relieved our bleak site. We have agreed not to operate <br />during a time of emergency winter feeding operations. We have been in contact with <br />the CDOW and their comments will be sent directly to you. <br />Error made -- fmal use to be open range-pasture. Rules 6, 4, 8 (1) and (2) do not <br />apply. <br />Exhibit I -Soils information to be provided during early March by Jolm Scott, <br />SCS. Vegetation information will also be included. Also, John will provide additional <br />climate information. <br />Exhibit K -Climate information. <br />Climate equal to Gunnison, Colorado. Elevation of site is 7,762 feet on top. <br />Temperatures vary from -50 in the winter to 90 in the summer. Typical high desert <br />climate. Vegetation indicates very dry conditions, sage, short grasses and occasional <br />small juniper. Further information will be included in Jolm Scott's report. <br />Exhibit L -Reclamation Costs. <br />The fmished pit floor area will be approximately 20 acres. The final elevation of <br />the pit floor will be overdrilled and shot about two feet below fmal grade to allow for <br />root growth and moisture storage. This overshot material will remain in place and not <br />have to be moved or replaced. At your suggestion, we will stockpile all available soil <br />and vegetation from the site and also additional yards of crusher fines or decomposed <br />granite to make a total of 10,750 cubic yards stored for reclamation. By loosening the <br />subsurface by blasting during normal mining operations, ripping will not be required. <br />About two inches of crusher fines or decomposed granite will be spread over the final <br />elevation of the pit floor. Then approximately two inches of soil and previous <br />vegetation will be spread both by scatterdumping with dumptrucks or scrapers and <br />spread with a motorgrader. Dozers will no longer be required with the additional <br />blasting depth. Average haul distance from stockpile area is 675 feet. We estimate six <br />loads per hour per truck with off road load of 14 cubic yards per truck. This equates to <br />84 cubic yards per hour per truck. Two trucks would be the most efficient with a 3.5 - <br />4 cubic yard loader and one motor grader; loading, hauling, dumping and grading about <br />168 cubic yards per Hour. This would require 64 hours to complete. Loader rate <br /> <br />
