It is the largest backf fling action in the life of the mine. Since the mining slopes along the south and east side of the pit will be mined to final reclaimed slopes, they will not require backfiling. When mining occurs along the north side of the pit, the backfiliing of Phase 1A will alreal,'have occurred or will be in progress. Thus, the backfiliing of Phase 1A and 1 B will be the sciario at which material movement needs are greatest, thus leading to the largest bond. r The components of the worst-case reclamation scenario are as follows: 1. tBackfill and grade Phase 1A to the final contour �., a. 236,192 CY of backfill placed via loader, haul truck, and dozer from stockpile in Phase 1 C. b. Rip all 5 acres to a depth of 12 inches 2.�1 „ ckfill and grade Phase 1 B to final contour { , a. 138,904 CY of backfill placed via loader, haul truck, and dozer from stockpile in Phase 1 C. b.
