TABLE 2.05.3(3)10-4 <br />RECLAMATION CALCULATION SHEET <br />Surface Disturbance <br />Five drill pads with a total disturbance of about 9,000 ft2 or 0.21 acre. The pads are in an area that historically has <br />been considered dryland pasture. Revegetation of this land type is with seed mix #8 at a drilled rate of 5.7 <br />pounds/acre. The 2004 price for seed mix #8 was $2.62/pound. <br />Seed Cost <br />Rounding the 2004 cost to $3.00/pound and increasing the application rate to 24pounds per acre <br />for broadcast seeding (2X drilled rate for broadcasting x 2"just-in-case" = 24) yields a per acre seed cost of $72.00 <br />Recontour pads to approximate original contours <br />2 hrs 2CY bucket excavator or equiv x $200/hr (includes mob-demob <br />far local wntractor) =$400.00 <br />0.21 acre of disturbance x $72 =$15.12 <br />Labor to broadcast seed 1 hr x $20.00 = 20.00 <br />Surface Disturbance Subtotal $435.12 <br />Hole Abandonment (14 holes at aoprox 60' ea) <br />Hole Sealing <br />WFC estimates that each hole will be dry. Hole sealing will consist of backfilling the holes with bentonite <br />chips and then placing a 10 foot concrete plug from -3 to -13 feet. The top three feet of the hole will be backfilled <br />with native soil. <br />Hale Plugging <br />Materials <br />14 boreholes x 47 ft (60 ft avg depth - 13 feet concrete + topsoil) = 658 lin ft <br />658 lin ft X 12 Ibs Baroid-type bentonite chips/ft 7,896 Ibs <br />7,896 Ibs x $0.20/Ib = =$1,579.00 <br />14 boreholes x .136 ft3lborehole ft = 1.90 ft3 <br />1 80# of dry mix concrete = .66 ft3 <br />each drill hole plug will need 2.88 bags (say 3) <br />3 bags x $5 ea = $15.00 x 14 holes = $ 210.00 <br />Labor for sealing and plugging <br />42 hrs x $20.00/hr = $ 840.00 <br />Hole Abandonment Subtotal $2,629.00 <br />Total $ 3,064.12 <br />Misc.
