. Assuming 50% reseeding will add $5,934, resulting in a total revegetation cost of $17,802. <br />Blocking access to the reclaimed Whirlwind portal azea will be more difficult than the Packrat road <br />because the azea is open and the slopes aze relatively gentle. It may be preferable to leave the fence , nd <br />gate along the road in place until the azea has achieved revegetafion standards and then remove them at <br />the same time as the sediment pond. For reclamation costing purposes, construction of a berm and <br />ditch over a 200-foot linear distance is assumed in this area along with the strategic placement of <br />boulders salvaged from the Packrat road berm. This work would be done with a D-7 dozer or <br />equivalent at an estimated cost of $2,500. The total cost for revegetation and blocking site access is <br />estimated to be $20,302. <br />U <br /> <br />Whirlwind Mine June 07 E-18 <br />
