. Please include a cost for ripping the facility area. <br />Impoundments <br />The Division reviewed the performance bond estimate to reclaim <br />impoundments located on the HG Loadout Facility Mine. Please <br />address the following concerns: <br />1. Peabody used the cost of a D10N to reclaim the sediment <br />ponds located on the mine site. The Division recommends using a <br />D8N Dozer to reclaim the ponds because the D8N Dozer is less <br />expensive than the D10N Dozers for this size task. Please also <br />remember that reclamation of the ponds will not be performed at the <br />same time of backfilling and rough grading of the mine site. The <br />Division estimates the cost of a D8N to be 104.44/hr. based on a <br />single shift. If you believe that D8N Dozers are more appropriate <br />to reclaim the ponds, please change the bond estimate to <br />incorporate this cost. For further clarification of the cost of <br />D8N Dozers, please see the attached cost report sheet. <br />2. Please inform the Division of the push distance used to <br />reclaim the ponds. It appears that page 1 and page 3 of the <br />Earthmovinq Fundamentals report is missing form the submitted bond <br />estimate. Please submit these pages as well as state the average <br />push distance used in the program. <br />3. Please include a cost for reclaiming the Leach Field <br />area. The equipment cost and correction factors should be similar <br />to the factors used in the pond reclamation. <br />4. Please include a cost for regrading the ditches. <br />According to Exhibit 12-2, numerous ditches are located at the HG <br />Mine Facility. These ditches will most likely be reclaimed the <br />same time as the ponds. Please include a cost for regrading the <br />ditches using a D8N Dozer or a motor grader. <br />Final Grading <br />Peabody did not include a cost for final grading of the <br />reclaimed area. The Division recommends using a 14G motor grader <br />at $87.16/hr based on a single shift. The Division feels that <br />rough grading roughly 100 acres would cost $5,866.00. Please see <br />the attached cost report for further detail on 14G motor graders. <br />Roads <br />The Division reviewed the cost estimate summary regarding road <br />reclamation and has the following concerns: <br />1. All road reclamation should be conducted on a single <br />shift. Please change the operating cost accordingly in the bond <br />estimate. <br />
