Candy Thompson - 2 - March 4, 1986 <br /> refuse pile. Mid-Continent may wish to provide an alternate scenario and <br /> detailed cost estimate for the reclamation of the prep plant area. <br /> The original backfilling costs for the roads were based on decreasing the road <br /> widths from 22 feet to 11 feet. However, although the permit application <br /> states that the roads are 22 feet wide, field inspection and the 1983 Haul <br /> Road Report from Geo-Hydro Consulting indicates that the roads are 50-60 feet <br /> wide. I have based the B and G costs for the haul roads on decreasing the <br /> road widths from 55 feet to 11 feet. The road length was taken from the <br /> Geo-Hydro report (14.74 miles). Mid-Continent may wish to provide an <br /> alternate, detailed backfilling plan. <br /> Backfilling and Grading Costs <br /> No. 1 Mine <br /> D9 dozer: 435 hrs x $158.68/hr = $69,026.00 <br /> No. 2 Mine <br /> D9 dozer: 146 hrs x $158.68/hr = $23,167.00 <br /> No. 3 Mine <br /> D9 dozer: 3140 hrs x $158.68/hr = $498,255.00 <br /> No. 4 Mine <br /> D9 dozer: 1297 hrs x $158.68/hr = $205,808.00 <br /> No. 5 Mine <br /> D9 dozer: 420 hrs x $158.68/hr = $66,646.00 <br /> Rock Tunnel Portal <br /> D9 dozer: 390 hrs x $158.68/hr = $61 ,885.00 <br /> Haul Roads <br /> 245 backhoe: 7375 hrs x $178.24/hr = $1 ,314,520.00 <br /> D9 dozer: 260 hrs x $158.68/hr = $41 ,257.00 <br /> Additional Mine Roads <br /> increased rental rate @ 1 .075 percent <br /> of original cost, based on increased <br /> rental rate only. _ $105,791 .00 <br /> Sediment Ponds <br /> D9 dozer: 38 hrs x $158.68/hr = $6,030.00 <br /> Wash Plant Area <br /> 988 B loader: 200 hrs x $107.96/hr = $21 ,592.00 <br /> (3) 773 B trucks: Geo hrs x $115.81 /hr = $69,486.00 <br /> D9 dozer: 600 hrs x $158.68/hr = $31 ,736.00 <br /> III.
