(c) The only water diversions would be for stormwater management to keep all stormwater <br />• from running into or off site, and for erosion control. <br />No water impoundments are planned at this time, however, if water for processing would <br />become available at a future date, all the needed water system and controls would be <br />engineered for this site. <br />(d) The proposed mining would be done in the direction shown on the Mining Plan Map - <br />Exhibit "C" of this application. The area disturbed would not exceed 20 acres at any time, <br />including haul roads and processing areas. <br />(e) An approximate timetable to describe the mining operation is shown on the Mining Plan <br />Map -Exhibit "C". The life of this mine may extend beyond the 50 years. It is proposed to <br />use a floating bond on 20 acres on this operation as mining is completed in the mining <br />units as proposed (see Mining Map Exhibit "C°). <br />(i) The estimate of the periods of time which is stated above, is between 3 to 5 years to <br />establish the reclaimed area back to rangeland that may be considered for release by the <br />Mined Land Reclamation Board of the Division of Mining and Geology. The reclamation <br />will be an ongoing process as soon as the first unit is deemed mined-out, and the phasing <br />of the mining and reclamation will follow a natural progression with final reclamation as the <br />ultimate goal. <br />• (ii) As stated in this report, the mining units will range between 5 to 20 acres with a <br />maximum of 20 acres being disturbed at any time. Reclamation would be occurring on the <br />lands mined out concurrently with mining. <br />(iii) The sequence in which each stage or phase will be carried out is outlined in this report. <br />Also, please see Mining Map Exhibit "C". . <br />(f) The backsloping and final pit floor will be done contemporaneous with the mining. It <br />is planned to start reclaiming 5 to 10 acres, as they are deemed mined-out. This allows <br />the operator the allotted time to establish a planned reclamation plan and continue to mine <br />hence the 20-acre floating bond. <br />As stated before, this site is on an upland terrace deposit with the following characteristics: <br />(i) The areas to be mined are as follows: USDA Soil Unit 77 -Schamber-Midway <br />complex, 3 to 25 percent slopes. This map unit is on hills, terrace edges, and side <br />slopes. The native vegetation is mainly grass. Elevation is 5,500 to 6,600 feet. This unit is <br />about 65 percent Schamber sandy loam and about 20 percent Midway clay. The Schamber <br />soil is in the gently sloping areas and on the hilltops, and the Midway soil is on the steeper <br />side slopes. The components are intricately intermingled. Included in this unit is <br />approximately 75 percent Kim fine sandy loam on foot slopes and in drainageways. <br />l~J <br />
