MINING PLAN EXHIBIT D(coNT) <br /> proposed sloping plan for the excavated area should eliminate <br /> any concerns of erosion occurring on the site. <br /> On a typical operation of this type up to 3 ac-ft of water <br /> per year will be used for dust control . Most of the water used <br /> for dust control will be used on haul roads . Please refer to <br /> EXHIBIT G -WATER for the discussion of how water will be used at <br /> the site and the source of said water. <br /> There are no ditches crossing the site and no surface or <br /> subsurface water will be impacted by the mining operation. All <br /> interior pit slopes will be maintained with a pit-ward attitude <br /> so that historic drainage patterns can be maintained. This <br /> same slope management plan will prevent any offsite slides or <br /> other disruptions . All stormwater contacting the disturbed area <br /> will be retained on site and allowed to evaporate or soak into <br /> the underlying gravel and will not be retained for more then 72 <br /> hours . No U.S. Army Corps of Engineers 404 permit is <br /> necessary, as there are no water bodies on the site nor are <br /> there any wetland areas that will be disturbed by mining or <br /> reclamation. <br /> MINING TIMETABLE <br /> If there are changes in the mining timetable we will <br /> discuss the reasons for the change in the annual report that <br /> follows the change and modify it at that time. <br /> ESTIMATED MINING TIMETABLE <br /> ACRES ± <br /> ESTIMATED TOTAL TOTAL MINED MINED <br /> YEARS AREA MINED 100% SLOPES <br /> 35-45 44 .49 40 . 01 28 . 31 11 . 17 <br /> Big Bull Dog Trucking, Inc.
