Michael S. Savage Page 2 January 5, 2006 cubic yazd for the 4,805 cyds of rock filter and rock riprap, which is similaz to a gravel pit production cost. The prices used in the Task 24 spreadsheet of the draft estimate ($13.47/cyd for filter and $17.06 for riprap) reflect the prices available to a third-party conducting reclamation on the Carbon Junction site. Task 25 -The draft estimate uses an excavator as proposed in the TR-13 submittal. Tasks 29 and 30 -The draft estimate eliminates Task 29 (haul 3,000 cyds of topsoil from stockpile #2 to reconstructed channel) and Task 30 (seed, mulch, and fertilize reconstructed Carbon Junction Canyon channel) because, as noted in the TR-13 submittal, these tasks are not in the reclamation plan. Tasks 31a, 316, 31c -The draft estimate subdivides tasks for reclaiming sediment ponds 001 and 002. Task 31c was added to provide a riprapped channel that would be necessary to control erosion in the pond 002 fill. Task 42 -The draft estimate includes an estimate of costs for disassembly and removal of equipment and other materials from the equipment yazd at the south end of the permit area, reflecting the Division's general cost estimating policy of not including credit for equipment salvage, Task 44 -The draft estimate includes hauling of topsoil for fill (and for revegetation) from stockpile #4 to the equipment storage area as shown on page 5-30 of the reclamation plan. Task 44 previously included only topsoil for revegetation. Tasks 50 and 51 -The draft estimate adds these new tasks (rill gully maintenance and weed control). The 10-yeaz maintenance period is a contingency for not achieving the approved alternative postmining land use. The draft estimate retains the following tasks which the TR-13 submittal proposed for elimination: Task 2 -This task is necessary to account for item 2 on page 5-24 of the approved reclamation plan (also shown as Task 2 on page 5-35 of the plan). Task 3 -This task was retained, rather than adding its 6,423 cyds of dozer work to the 4,000 cyds of excavator work in Task 1 (as proposed in the TR-13 submittal). Task 16 -This task is needed to account for what is shown as Task 4 on page 5-36 of the approved reclamation plan. Task 28 - Surveying is work that apparently has been completed and, therefore, would need to go through the bond release process before elimination from the cost estimate.
