<br />s'C APPENDIX 5-7 <br /> <br />BONDING <br />The bonding calculations for the Carbon Junction Mine has <br />been recalculated based upon the changes in the mine plan, pit <br />size, facilities and activities established as a part of this <br />permit. More specifically, the bonding calculation set forth <br />in the following will be determined in accordance with the <br />procedures for the MLRD to retain a qualified company to <br />perform this reclamation under bond forfeiture scenarios. <br />Two bond forfeiture scenarios have been examined to <br />determine the maximum bond necessary to reclaim the mining <br />activity during various stages of the activity. The two <br />scenarios to be examined are as follows: <br />#1 - Reclamation of current activities. (See Table <br />II.) <br />#2 - Reclamation of Maximum open pit at South end. <br />(See Table III.) <br /> <br />There are a number of common reclamation activities to <br />each of the above scenarios. These common reclamation <br />activities (See Table I.) have been identified as: <br />1. Fill <br />2. North Pit on Rock Slope <br />3. Equipment Storage Area <br />4. Powder Storage <br />5. Sediment Pond No. 1 <br />6. Sediment Pond No. 2 <br />7. Drill Holes <br />8. Temporary Roads <br />Table I is a breakdown of these activities, reclamation <br />procedures and costs for the common reclamation activities. <br />Support calculations follow Table I and are appropriately <br />referenced to Table I. <br />The first reclamation scenario is the reclamation of the <br />current activities as of 1/92 submitted as a part of this <br />permit. The details of reclamation costs have been shown in <br />Table II and also could be referenced to Map 5-7. <br />The second reclamation scenario has been identified as <br />the reclamation of the maximum open pit at the south end of <br />the mining activity. The details of the cost associated with <br />this reclamation scenario has been established in Table III. <br />• The most cost effective method of filling the 1.2 million <br />yards of open pit in the south is to shoot the highwall and <br />"cast blast" material to the pit in combination with dozer <br />pushing of material from the south end of the pit and the <br />"fill" area. <br />JAN 1 , ;gog <br />
