No water impoundments are planned at this time; however, water for processing will <br />become available at a future date. At that time all the needed water systems and controls <br />would be engineered for this site. At the time of needing water to wash aggregates the <br />operator will most likely get the water from a nearby well and run a pipeline to this site. The <br />State Engineers Offrce will be noti{ed and all of the proper permits will be obtained and in <br />place before the washing operation would begin. The Division of Minerals and Geology / <br />MLRB Office will also be informed. <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 10 acres at any time, <br />including haul roads and processing areas. The 10 acre section that is active shall not have <br />more than 5 acres being excavated atone time and the remainder shall be in the process <br />of being reclaimed as requested by the Division of Wildlife and the Custer County Board <br />of County Commissioners per the granted S.U.P. on November 7, 2002. <br />(e) An approximate timetable to describe the mining operation is shown on the Mining Plan <br />Map -Exhibit "C". The I'rfe of this mine may extend beyond the 50 years. It is proposed to <br />use a floating bond on 10 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 recaimed 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 15 acres with a <br />maximum of 10 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 in concert with the mining. It is planned <br />to start reclaiming 5 acres as they are deemed mined-out. This allows the operator the <br />allotted time to establish a planned reclamation plan and continue to mine, hence the 10 <br />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 8 - Coutis sandy loam, 2% to <br />5% slopes. This is a deep, well drained soil in drainageways and foot slopes. It formed in <br />mixed alluvium. Elevation is 7,800 to 8,800 feet. Typically, the surface is dark brown sandy <br />loam 11 inches thick. It is underlain by dark sandy loam 37 inches thick. The substratum <br />is brown gravelly loam to a depth of 60 inches or more. This Coutis soil is a good source <br />of topsoil. <br />
