. 14. Seeding, Mulching, and Blocking of Packrat Road <br />The backfilled surface will be reseeded as segments of road aze reclaimed, since there will be no future <br />access. The methods are the same as that described for the Packrat Portal area in Section 12 of this <br />Exhibit. As measured from Figure E-1, the width of azea to be reseeded is 25 feet times the road length <br />of 1,660 feet = 41,500 squaze feet (sf) or 0.95 acres. The unit cost is $1,500 per acre, which includes <br />50% reseeding resulting in an estimated cost of $1,425. <br />s <br />Boulders salvaged from the road berm will be placed across the road entrance to discourage access by <br />recreational vehicles. This work will be done with a front end loader at an estimated cost of $300. <br />Total estimated cost for seeding, mulching, and blocking the road is $1,725. <br />Therefore, the total cost of this task is $1,425 + $1,725 = $3,150. <br />15. Rip Compacted Traffic Areas of Whirlwind Mine Prior to Topsoiling <br />The Whirlwind portal bench, access roads, facility azeas and top of waste embanlanents wilt be ripped <br />to a depth of 2.5 feet prior to topsoiling to relieve compaction from vehicle traffic. The total area to be <br />ripped is 7.41 acres and the estimated unit price is $300 per acre resulting in a total cost of $2,223. <br />16. Topsoil Replacement on Remaining Areas of Whirlwind Mine <br />As shown on Map F, the remaining areas that will require topsoiling at the end of the mine life aze the <br />water treatment azea, called Area #1, which is 2.35 acres in size. The Whirlwind portal bench, and the <br />eastern portion of the waste embanlanent aze called area #2, which is 5.72 acres in size. The total azea <br />for re-topsoiling is 8.07 acres. The replacement thickness is from 12 to 16 inches with an expected <br />average of 14 inches, therefore, the volume to be spread and graded is 15,189 cubic yards. As shown in <br />Exhibit D, 15,324 cy are available from the three stockpiles. <br />The required topsoil will be obtained from the following stockpiles: <br />Whirlwind Mine June 07 E-16 <br />
