Using the acreage table for Task I for for this task should be very minimal. It is revegetation, it is seen that the total haul estimated that the actual cost for this work road area is 99.3 acres, of which the DMG shoiuld be $1000 per acre instead of$3721 per has reclaimed 52.9 acres or 53%of the total acre for the entire road area of 99.3 acres. area. The DMG credit for this task is Therefore, the total cost for this task should be therefore 53%of$369,577 or$195,875. $99,300, not$369,577. The actual cost of the remaining work is therefore 47%of the 99.3 acres x $1000 per acre or$46,671. 17 Backfill Rock $41,6 32 $0 $0 $24,979 $16,653 $16,653 The actual cost of this work is estimated to be This area is currently being completed by Tunnel to Prep Plant identical to the remaining bond amount. the DMG(September 1997), All upper areas Area are done from the rock tunnel to immediately above the prep plant area. Some backfilling immediately above the prep plant remains to be done. All pad areas near the creek are ready for revegetation. It is estimated that 6O%of the backfilling work is done for this task. Therefore the DMG credit for work completed is 600/0 of $41,632 = $24,979.
