I• <br /> <br />Topsoiling was broken down into two tasks: 1) Topsoiling the approximately 9,200 feet of <br />spur track, north of the loop area (costs were also included for support equipment and a <br />D10N dozer was used to push the topsoil off the side slopes for later distribution); 2) <br />topsoiling the remaining loop track area and facilities areas including Haul Road 2. <br />Revegetation <br />After the topsoil has been replaced, the seedbed must be prepared prior to seeding. This <br />is accomplished by ripping and disking the seedbed. Seeding is principally accomplished <br />using a rangeland drill. A11 costs, including fencing, are shown on the appropriate <br />aorksheets in Attachment 23-1. Areas to be revegetated are shown on the worksheet. A <br />revegetation maintenance fee of 20 percent was also included in case any of the seeded <br />areas required stand re treatment. <br />Facility Reclamation <br />• The following facilities, huildings, structures, and miscellaneous support items would <br />have to be demolishetl, disposed, and the area reclaimed once operations cease entirely. <br />The following discusses the reclamation of these structures. The attached worksheets and <br />tables show the pertinent volume and area calculations. <br /> <br />Structure Demolition. This estimate assumes that all structures within the Hayden Gulch <br />Loadout facility would have to be demolished and materials disposed. It also assumes that <br />no salvage value be attached to any of the structures. Means Site work Coet Data (1998), <br />was used to estimate these costs. Volume determinations were made from existing maps <br />and/or field measured. The cost per cubic foot includes disposal. Most costs, except <br />where noted, were based on a mixture of construction materials. Concrete is hauled to <br />railroad cut area. "' A11 information regarding structure volumes and coats can be <br />found on appropriate worksheets in Attachment 23-1. <br />Powe rl roes. Powe rl ine demolition was not estimated. Powe dines that run through the <br />permit area also service the Routt County Maintenance Yard and the Yampa valley Airport <br />and therefore the lines will remain in place. <br />3 Revised O6/00 <br />
