• equipment fleet. The conditions in determining the bond is to establish the maximum financial exposure in the life of the project during which the Division would exercise its rights to reclaim pursuant to bond forfeiture. These costs and associated activities are shown in Appendix 5-7. In order to establish the bond, it is necessary to understand the mining operation which has been explained in Section 2.05.1 through 2.05.3. At maximum exposure under the Development scenario, the largest pit will have been opened with the most volume moved to the fill area. Map 5-6 shows the maximum disturbance scenario with the lazgest "open pit" for the planned mine life. The maximum open pit will require a maximum of 850,000 cubic yards of fill to reclaim to Division requirements, which will be pushed to the pit. As the pit expands to the north, it will progressively become smaller and smaller, as can be seen from the cross sections. The moving pit concept uses newly mined materials to be placed at the south end of the steady-state pit. The bonding calculation uses a wncept of the optimal post mining land use with the best operational and cost effective method of reclamation of the "worst case" scenario. The details of the reclamation plan under the bond forfeiture scenario has been set forth in Appendix 5-7. • Ba~/Jiug and Crnding A plan for backfilling with reference to time, has been discussed above in Subsection (a) and is illustrated on Final Reclaimed Topography Map 5-4 and Geologic Cross sections A through X. Backfilling will be accomplished by the use of dozers pushing overburden/spoil from the benches into to the final excavated pits as much as possible. Much of the overburden will be hauled directly from a new bench cut to the backfill pit. These operations will require the use of one 988B Caterpillar End Loader, two to four 773B Caterpillar Trucks, one D-9HJD-8K Caterpillar Tractor dozer and one 637D Caterpillar Scraper. The plan for bacldlling and grading is different during normal reclamation procedure versus the bond forfeiture scenario of reclamation. The post-mining topography shown on Map 5-3 will achieve approximate original contour. In order to ensure compliance, the applicant will incorporate a verification plan into the permit application. OEI will submit a map, on an annual basis when actively mining, showing the topography of azeas reclaimed during the preceding year. This map will be submitted as part of the Annual Reclamation Report. The applicant has an approved permanent realignment of the Carbon Junction Canyon. This realignment constitutes a permanent diversion of surface flows subject to Rule 2.05.3(4). Therefore, the applicant has submitted a detailed plan prepared by or under • Technical Revision 08 (v 1.3) 5-23 Revised 9/1997
