• Should any type of fire or hazardous spillage occur at the mine area or the disposal area, the <br />person in charge of mine operations is responsible for evaluating the situation, evacuating the area <br />if required, and allowing only authorized personnel to attempt to rectify the danger. <br />The operator has developed contingency plans for emergencies such as a fire in the coal waste <br />bank, a fire in the petroleum storage area, a spillage of petroleum, etc. These plans have been <br />submitted to the appropriate regulatory agencies prior to the start of mine operations. <br />V.E Disposal of Mine Development Waste <br />During the grading of the "D" Portal and Ventilation Entry areas and construction of the mine entry <br />tunnels at the "D" Portal Area, cut materials were used as fill for the construction of the pads, level <br />areas, and roads. If cut material was more than required for fill, the excess cut material was either <br />stockpiled for use during final regrading or transported to the Refuse Disposal Area by truck, <br />stockpiled, and used later as cover for the coal waste banks. If material unsuitable for fill or cover, <br />such as large amounts of oxidized coal, was encountered, it was trucked to the Refuse Disposal <br />Area and disposed of in the same fashion as if it were coal processing waste. As previously <br />discussed in Section IV -1 (Grading Plan), a maximum of 30,000 cubic yards of excess cut material <br />was generated at the "D" Portal Area. In addition to site development excess cut material, approxi- <br />mately 10,000 cubic yards of rock was generated during construction of the mine tunnel entries. <br />• This material was either used in embankment construction or disposed of in the refuse disposal <br />area. <br />n <br />�J <br />After mine operations commenced, any development waste was transported to the preparation <br />plant waste hopper, mixed with coal processing waste and disposed of in the Refuse Disposal <br />Area. <br />V.F Sealing of Mine Openings and Drill Holes <br />All mine openings and drill holes are located, designed, and constructed to prevent gravity <br />discharge of water from the mine. <br />All exploration holes, drill holes, shafts and wells are cased or otherwise managed as approved by <br />the regulatory authority. Holes uncovered or exposed during mine operations are permanently <br />plugged unless approved for water monitoring or otherwise managed as approved by the regulatory <br />authority. <br />Drill holes or wells which the Bureau of Land Management (BLM) wishes to retain for use as water <br />wells shall be transferred to the control of the BLM as per Section 4.05.14. <br />Except for wells transferred to BLM control and openings required for ventilation of the mine, all <br />other holes or openings will be permanently sealed at the end of their useful functions. <br />Mid -Term Review 2002 (8/2002) V -17 <br />
