I • 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. All costs, including fencing, are shown on the appropriate <br />worksheets in Attachment 23-1. A revegetation maintenance fee of 20 percent was also <br />included in case any of the seeded areas required stand retreatment. <br />Facility Reclamation <br />The following facilities, buildings, structures, and miscellaneous support items would <br />have to be demolished, 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 />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. The CIECES Cost Estimation <br />Software was used to estimate these costs. Volume determinations were made from existing <br />maps, Table 12-3 and/or field measured. The cost per cubic foot includes disposal. Most <br />costs, except where noted, were based on a mixture of construction materials. Concrete is <br />hauled to railroad cut area. All information regarding structure volumes and costs can be <br />found on appropriate worksheets in Attachment 23-1. <br />Powerlines. Powerline demolition was not estimated. Powerlines 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 />Facility Areas. After the buildings are demolished and disposed, the site is reclaimed. <br />Three feet Of material will be ripped in the facilities area. The top one foot of <br />gravel/scoria surfacing on the parking/storage areas will be dozed into a cut or low area <br />adjacent to the facility. This material will be coveted during the gratling process. <br />Concrete foundation areas will be hauled to a railroad cut area for disposal. Monitor <br />wells HGDALI and HGDAL2 were abandoned as part of TR-06, monitor well HGDA13 will be <br />• abandoned during final reclamation <br />TR-06 3 Revised OS/OS <br />
