The remaining material generated from the grading of the ponds will be used to reclaim the Lower Mine <br />Area. This leads to a total of 734 cubic yards of material that will need to be moved via dozer to re- <br />contour the ponds at a cost of $0.75 per cubic yard. This leads to cost of $0.75 per cy x 734 cy = $551. <br />10. Reclamation of ventilation shafts (4) by sealing with surface excavation, plate and polyurethane foam, <br />as described in the reclamation plan (Exhibit E) The cost is $3,580 per vent shaft. The estimated cost is <br />$3,580 x 4 shafts = $14,320. <br />11. Placing soil material on all remaining disturbed areas of the site (excluding waste embankment) to a <br />depth of 6 inches This area includes the Lower Mine Area, which consists of the area of the mine <br />building, fuel tank, portal area and other minor areas. The subtotal is 1.2 acres. Therefore, the total area <br />requiring topsoiling is 1.2 acres which will require 968 cy of soil to be imported to the site. The cost of <br />placement is expected to be $1.20 per cy. Therefore, the total cost is $1.20 per cy x 968 cy = $1,161.60. <br />Roads will be left in place for future access to the site and will not be covered with soil material. <br />12. Ripping topsoil to a depth of 3 inches on an area of 1.2 acres This cost is $200 per acre for a total cost <br />= $240. The waste embankment area will be pocked and not ripped. <br />13. Seed This amounts to 1.3 acres and primarily consists of the waste embankment. The cost of the work <br />is $1,200 per acre. The cost is therefore 1.3 acres x $1,200 per acre = $1,560. <br />14. Hvdroseed and mulch on all slopes greater than 3H:1 V Broadcast seed and mulch on all slopes 3H:1V <br />or less. This is 6.9 acres and primarily consists of the upper mine area ponds, ventilation shaft areas and <br />other minor areas. The cost of this work is $600 per acre. The cost is therefore 6.9 acres x $600 per acre <br />= $4,140. <br />15. Mobilization costs will consist of the following: <br />i. CAT track hoe $1,500 <br />ii. CAT D -7 $1,200 <br />iii. 2 tandem trucks $600 <br />iv. Seeding equipment $1,500 <br />Total mobilization cost = $4,800. <br />L -4 <br />
