• Soil Salvage and Storage. The disturbance azea from which soil was salvaged and the soil stockpile <br />sites as of December 31, 2004 aze shown on the Yoast Mine 2004 Reclamation Map. During 2004, <br />there was soil salvaged from 20.4 acres all of which was live handled and respread on reclaimed land, <br />in addition soil was removed from stockpiles L, M and Q and respread. <br />The volume of soil remaining in stockpiles as of December 31, 2004 was determined by Geld survey. <br />The stockpile volumes as of December 31, 2004 aze listed in Table 04.1. As of December 31, 2004, <br />there were 596.9 acre-feet of soil stockpiled in the mining area. <br />Soil Replacement. Topsoil was replaced on 64.8 acres of disturbed area in 2004. Therefore, the <br />total remaining life-of--mine disturbance azea requiring topsoil as of December 31, 2004 is 492.2 acres. <br />Soil Replacement Thiclmess. The soil balance as of December 31, 2004 for the remaining life-of- <br />mine is calculated as follows: <br />Mine Area <br />Total disturbance area = 858.9 acres <br />Permanent Facilities & Topsoil replaced = 366.7 acres <br />Disturbance area requiring soil = 492.2 acres <br />Soil in stockpiles (T'able 04.1) = 596.9 acre-feet <br />Mean replacement depth available = ].2 feet <br />By dividing the soil available by the area requiring soil replaced, we arrive at the 2004 soil balance <br />thickness of 1.2 Eeet for the thine azea. Enough topsoil has been salvaged to reclaim the existing <br />• disturbance with the permitted tninimum replacement thickness of 1.0 foot <br />• Seeding and Shrub Planting <br />A total of 64.5 acres were seeded/planted in 2004. The area was seeded using Seed Mia #IA (see <br />Table 04.1, Seed Mix #lA, for constituents). <br />No concentrated shrub seeding was conducted in 2004. <br />Shrub Plots. Approxanately 6,250 seedlings were planted at Yoast; locations of the sites are shown <br />on the attached 2004 Reclamation Map. Following is the breakdown indicating the number of <br />seedling species planted in each azea. <br />North Area <br />Gambel oak 200 <br />Serviceberry 400 <br />Chokecherry 350 <br />Mtn.
