• <br />placed by CF&I. There is no soil or vegetation supporting material in this area to be <br />quarried. This overburden must first be removed to expose the ore to be quarried. The <br />overburden ranges in thickness from 0 foot to I50 foot. The overburden removed in <br />preparation for mining will be temporarily placed on the permit area as quarrying <br />progresses. Mining will commence on the northeast part of the ore outcrop and proceed <br />along the outcrop to the southwest. Once the quarry is opened up to a workable size, the <br />initial and ongoing overburden will be placed back in the quarried out area. This quarry <br />"hole" will move and progress much like a strip coal mine thus minimizing the disturbed <br />area open at any one time. In mining down from the present bottom of the quarry, there <br />will be no new area disturbed that was not disturbed by CF&I. <br />Although no water is expected to be encountered in any mining operations, the <br />northwest part of the pit shall be retained as a settling basin for any rain, run-off or <br />ground water encountered. Should excessive groundwater be encountered, it will be <br />directed or pumped to this settling pond before being discharged into the South Arkansas <br />River, the main drainage of the Monarch Pass area. <br />Unconsolidated overburden will be dug with excavators or front-end loaders and <br />hauled by off-highway rock trucks to the dispersal or stockpile area. "Shot rock" <br />overburden will be handled the same afrer being mined. Mining will be with quarry rock <br />drills and blasted with quarry approved explosives. Mined limestone or dolomite will be <br />loaded and hauled to a portable crushing plant located on the premises or transported off <br />premises to a reduction plant or directly to market. <br />The size of the areas to be mined, excluding stockpile area should not exceed let] <br />acres at any one time. Dimensions of a quarry pit will be about 850 to 900 foot long and <br />175 to 270 foot wide. <br />Removal of the spoils stockpile will commence immediately and continue until <br />the stockpile is depleted. "Mine life" of the spoils stockpile is estimated to be 10 to 30 <br />years, depending on market. <br />Also, depending on the market, quarrying could start immediately and from <br />presently known reserves could last for 20 years. <br />What product and when it will be mined will be dictated by the limestone and <br />dolomite markets. <br />Existing roads will be utilized to remove the spoils pile and to quarry the <br />"sublevel" limestone or dolomite. Access to the limestone deposit on the wall of the <br />quarry will be by easements contained in Exhibit O. All roads will be graded and <br />bermed to MSHA requirements and shall not exceed a l0 percent grade. <br />It is probable that there will be no disturbance of existing hydrology. However, if <br />ground water is encountered, only minor temporary disruption of natural groundwater <br />2 <br />
