<br /> <br />16. Communications facility located in the SE', of the NE; of Sec 25 1.00 acres <br />17. Exhaust stack site located in the NE; of the NE; of Sec 25 1.00 acres <br />Total land disturbance expected 73.65 acres <br />The location of these areas are shown on Exhibit F and coincide with the <br />numbering above. <br />B. No earth moving is contemplated. <br />C. Water diversion or impounding facilities are the two overflow ponds already in <br />existence, and the sediment impoundment described in the Reclamation Plan. <br />D. Moderate Disturbances: <br />A site of approximately 24988-ftz, graded and leveled, will be required to set <br />up raise boring equipment for boring ventilation and off-gas raises. <br />Another site of approximately 40,000 ft2 will be leveled and graded to provide <br />an area for the processing facilities. The dump site, when filled to the 8.6 <br />million yd3 capacity, will require approximately 30 acres. <br />Access roads will have to be provided to each of the above areas. However, <br />existing roads lie very close to the proposed areas and it is anticipated that <br />less than 200 ft of additional road will be necessary resulting in a disturbed <br />area of approximately 2,800 ft2. <br />E. Timetable: <br />The enlargement of the lower dump will take place at about 16,250 yd3 per month. <br />This rate will remain relatively constant depending on the number of working <br />areas available underground and the amount of equipment breakdowns that are <br />encountered. <br />Work on the processing area should start in July and take approximately two <br />months to complete. The location of the processing area will be situated so that <br />as little leveling as possible will have to be done. <br />The 24,000 ft2 are necessary for the raise boring will be constructed when the <br />initial access drifts are completed to the proposed retorts. The access mining <br />is scheduled to be completed by November and the preparation and raise boring will <br />continue through next year. <br />This facility is expected to remain a research and development activity for the <br />foreseeable future. Revegetation of the raw shale will begin within one year <br />of any area becoming inactive, such as benches not being used as part of the <br />ongoing operations. The slopes of the dumps and other affected areas will be <br />prepared for revegetation activities upon abandonment which is anticipated to be <br />in the year 2040. The life of the mine is expected to be 63 years. <br />
