TABLE 2.05.3(3)10-6 <br />RECLAMATION CALCULATION SHEET <br />Surface Disturbance <br />Three drill pads with a total disturbance of about 5,400 ft2 or 0.12 acre. The pads are in an area that historically <br />has been considered dryland pasture. Revegetation of this land type is with seed mix #8 at a ddlled 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 />for local contractor) =$400.00 <br />0.12 acre of disturbance x $72 =$8.64 <br />Labor to broadcast seed 1hr x $20.00 = 20.00 <br />Surtace Disturbance Subtotal $435.12 <br />Hole Abandonment (14 holes at aoorox 60' eal <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.
