Tab 21, Minesoil Reconstruction, in the PAP, indicates an estimated average of 1.8 feet (21.6 inches) will be replaced over final graded spoil in the mine area and 1.1 feet will be replaced along Haul Roads A and B and the facilities in Section 8. As determined by the 2005 mine wide sampling, topsoIl replacement to date of 22.6 inches is right in line with the original projections of 21.6 inches. REVEGETATION • Seeding and Shrub Planting A total of 96.6 acres were seeded/planted in 2005. Of that, 9.9 acres were newly established shrub plots. The azea was seeded using Seed Mis #IA (see Table 05.2, Seed Mix #lA, for constituents). Concentrated shrub seeding was conducted in 2005, in the areas where the seedling shrubs were planted. Shrub Plots. Approximately 18,200 seedlings were planted at Yoast; locations of the sites aze shown on the attached 2005 Reclamation Map. Following is the breakdown indicating the number of seedling species planted in each area. Yoast 1 Gambel oak 1,700 Yoast 3: Along Drainage Serviceberry 5,000 Boxelder 3,000 Chokecherry 2 500 9,200 Yoast 2 .

The 2005 annual revegetation monitoring report is submitted as a separate document. • Weed Control Survey for noxious weeds was carried out on the Yoast Mine permit area in 2005. Monitoring was conducted in 2005 to deteutilne the need or level of retreatment necessary for areas sprayed in 2004. Canada thistle was the primary tazget species in all control areas, with lesser activity duec[ed towards areas of hounds tongue and whitetop. The applied herbicide consisted of a tank mix of 2.5 gallons of 22K Tordon and 2.5 gallons of 2,4,D with 250 gallons of water. Escort at the rate of one (1) oz. per acre was spot sprayed on the whitetop. Control areas were sprayed in June, July and September. A spot spray gun was used to concentrate control activities on target areas, reducing potential impacts to adjacent desirable vegetation. The herbiude mix, based on recommendations from the Colorado State Extension Service, was mixed and applied by the Seneca Mine Reclamation Manager and Dillon Contracting who are certified commercial applicators. The weed control azeas will continue [o be monitored in 2006 for effectiveness and necessary retreatment. See attached weed control daily log spreadsheet and the Weed Control Areas map for a more detailed description of the 2005 herbicide application.
