<br />MINING PLAN <br /> <br />EXHIBR D (CONT) <br />All interior pit slopes will be maintained with a pit-ward <br />attitude so that there will be no drainage off the affected land. <br />This same slope management plan will prevent any offsite slides <br />or other disruptions, and will also address some of the storm- <br />water runoff questions arising from the new Clean Water Act. No <br />water will be discharged from the pit, until we have a National <br />Pollutant Discharge Elimination System (NPDES) Permit that will <br />address dewatering and Stormwater Permit that is now required by <br />law. we have adequate-water-available-to-meet-the-r-equr-ements <br />for e~aporaflve loss. An application will be made for a well <br />permit-to address the need for evaporative losses associated with <br />mining in the ground water table. It may become practical in the <br />future to line the lake areas, making storage reservoirs of some <br />of them. If this is done the necessary permit changes will be <br />made. <br />MINING TIMETABLE <br />The continuing uncertainty of economic conditions in the <br />construction materials industry precludes an accurate forecast of <br />demand during the life of the mine. We therefore, elect to <br />estimate the mining timetable based on an average year and expect <br />a specific year to vary widely from the average. The estimated <br />life of each area is the calculated life of the area based on an <br />average yearly production. This list does not imply a mining <br />direction, but rather outlined the various lakes that will be <br />created during the life of the mine. <br /> :~~ ACRES ~ ~~ ~~ ~ ~ AVERAGE ANNUAL <br />MINING AREA YEARS <br />~TOTAL~~AREA~. <br />~~MINED.'AREA PRODUCTION <br />TONS/YEAR <br />Bluff Lake 10-16 143.71 92.83 600,000 <br />Confluence Lake 3-5 39.86 23.18 600,000 <br />Highlands Lake 4-6 78.03 42.78 600,000 <br />Longhorn Lake 18-20 207.73 118.22 600,000 <br />Lake St. Vrain 3-5 74.32 30.90 600,000 <br />Krystal's Leke 1-3 51.54 12.70 600,000 <br />Meadow Lake 20-30 212.34 154.10 600,000 <br />Sand Flats Lake 8-10 80.72 61.05 600,000 <br />Sharkey's Lake 47-50 351.15 296.73 600,000 <br />Totals 1,239.40 832.49 <br />10 ~ZL~1' ~S O <br />
