Road Reclamation. There are approximately 3,300 ft. of haul roads (HGLF-HR1 and <br />HGLF-HR2) that will be reclaimed, and 400 feet of access roads that will be <br />reclaimed. It was assumed that this could be accomplished in three 8-hour <br />shifts by a D10N dozer. <br />Railroad. The track and ties will be removed from the site (no salvage value <br />was credited in the cost estimate). Ballast along fill areas will be picked up <br />and loaded by scraper to cut areas for use as backfill that will then be covered <br />with adjacent slope material. Cut areas will not require the disposal of <br />ballast material due to the fact that these areas will be filled in anyway. <br />Costs for this operation were determined using CIRCES. <br />Prior to pushing material into a cut area, the topsoil will be dozed out of the <br />way. Once the area has been rough graded, the topsoil will be re-spread with <br />dozers. After the areas have been topsoiled, then revegetation can take place. <br />Finish Grading. A cost has been estimated to finish grade the area with wheeled <br />motor graders. The CIRCES Cost Estimation Software was used to estimate grader <br />production; CDMG estimated 81.1 hours. Attachment 23-1 includes motor grader <br />production and cost worksheets. <br />Topsoil Replacement. Topsoil replacement volumes were based on the volume of <br />material in stockpiles as determined by the soil survey. The CIRCES Cost <br />Estimation Software was used to estimate scraper production. Attachment 23-1 <br />includes scraper product and cost worksheets. <br />Topsoil placement was broken down into two tasks: 1) Topsoiling the <br />approximately 9,200 feet of spur track, north of the loop area (costs were also <br />included for support equipment and a D10N dozer was used to push the topsoil off <br />the side slopes for later distribution); 2) topsoiling the remaining loop track <br />area and facilities areas including Haul Road HGLF-HR2. <br />Revegetation <br />After the topsoil has been replaced, the seedbed must be prepared prior to <br />seeding. This is accomplished by ripping and disking the seedbed. Seeding is <br />principally accomplished using a rangeland drill. All costs are shown on the <br />appropriate worksheets in Attachment 23-1.
