• hauled to an open pit for disposal. The entire parking area will be ripped to a depth of three feet. <br />Approximately one foot of topsoil from the topsoil stockpiles will then be hauled by scraper to the <br />ripped parking area. <br />Miscellaneous Utilities.. Underground utility reclamation, including phone lines, water lines, and <br />powerlines, will be abandoned in place. <br />Sediment Ponds. Three of the sediment ponds will be totally reclaimed (009, 015 and 0161, while two <br />(006 and 005) will remain in place as permanent ponds. Location of all impoundments can be found on <br />Exhibits 12-2 and 12-3. Embankment volumes were taken from existing, proposed, and typical designs <br />as shown in Tab 13. The embankment material and sediment accumulated from the ponds would be <br />dozed into the surrounding area fo reestablish the drainage. Aone-time cost for dredging sediment from <br />the ponds has also been included. <br />Road Reclamation. The three types of roads requiring reclamation within the mine site are haul roads <br />that are to be totally reclaimed, light-use roads that are to be totally reclaimed, and roads that are <br />presently haul roads but will be left for the postmine landowner and must be narrowed. There are <br />approximately 3.6 miles of haul roads that will be totally reclaimed, 2.1 miles of light-use roads that will <br />• be totally reclaimed, and 11.0 miles of haul roads and access roads that will be downsized for postmine <br />landowner use. <br />Light-Use Roads. There will be approximately 2.1 miles of light-use roads that will be reclaimetl. As a <br />general rule, these roads are not surfaced. The subgrade will be ripped, and the cut/fills will be graded <br />to cover the surface material. The culverts and embankments will be removed, topsoil respread, and <br />the area revegetated. <br />Haul Roads. There are approximately 3.6 miles of haul road that will need to be reclaimed. The <br />surfacing material will be hauled into the pit and buried as part of the final pit grading <br />Permanent Roads. There are approximately 11.0 miles of proposed permanent haul roads and access <br />roads. These roads will be narrowed to 20 foot wide for postmining use (see Tab 13 for detailsl. <br />These roads will take the place of jeep trails that existed in the area prior to mining and add <br />transportation routes that were not available prior to mining. <br />Fleet Determination <br />• Once the volumes for the various phases of reclamation were determined, the number of shifts, hours <br />per shift, equipment types, operator/operating efficiencies, support shifts, hours per shift, equipment <br />PR-OS 5 Revised 05/05 <br />
