Approximately eight inches of topsoil will be removed and stockpiled. Overburden depths, ranging from <br /> five to seventeen feet, and waste material will be removed and stockpiled. Clay will then be mined by <br /> first ripping with a dozer and then pushing it into stockpiles or by using a scraper. Average thickness of <br /> the clay lens is 27 feet, with the deepest area being 45 feet below the existing ground surface. <br /> Mining will not disturb more than 20.8 acres. Each segment will result in a topsoil stockpile, an <br /> overburden stockpile, and an excavated mine pit. Overburden will then be dozed back into the pit after <br /> each mining segment. Stockpiled clay will average 25,000 tons. A new stockpile will be started as the old <br /> stockpile is depleted. <br /> Clay will be hauled from the stockpile by loading into tractor-trailer trucks using a front-end loader. <br /> Mining equipment (dozer and scraper) will be located on the mine site during active mining operations <br /> only. As haulage will be on a demand basis, the front-end loader will remain on-site during hauling <br /> episodes. <br /> 2.3 Mine Phasing <br /> No more than 20.8 acres will be worked at any one time before reclamation commences. <br /> Time Table <br /> PHASE NUMBER ACRES APPROXIMATE APPROXIMATE* <br /> TONNAGE TIME PERIOD <br /> Phase 1 5.8 112,000 5.6 <br /> Phase 2 5.5 108,000 5.4 <br /> Phase 3 9.5 180,000 9.0 <br /> TOTAL 20.8 748,800 20 years <br /> *Assumes production of 25,000 tons of clay per year. <br /> 2.4 Reclamation Process <br /> The post-mining land use will be rangeland and wildlife habitat. All reclamation shall be completed by <br /> July 10, 2032. The approximate post-mining land form will result in a depression approximately 15 feet <br /> below the original ground surface with all slopes graded to no steeper than 3h:1v, as shown on the <br /> Reclamation Plan Map. <br /> Regular 112 Permit application for mining and reclamation will be submitted to the Colorado Division of <br /> Minerals of Geology at a later date. That permit application will also be submitted to Douglas County. <br /> The general reclamation process and purpose are presented below. <br /> Reclamation will take place concurrently with mining with no more than 20.8 acres being disturbed at <br /> any one time before reclamation commences. Vegetation will be removed, and then available topsoil <br />
