Sssiun - 2.05.4 along stream banks, Juniper Woodland habitat on the south- and southwest-facing slopes, and • Mountain Shmbland habitat on the somewhat more "mesic" east facing slopes. Disturbed azeas will broadcast seeded following necessary surface preparation. All disturbance areas will be broadcast seeded using equipment-mounted or hand broadcast seeders. Seed will be broadcast at the increased rates specified in the seed mixtures and seeded areas will be harrowed, raked, or dragged to bed and cover the seed. Seeded areas will be mulched with straw or native mulch at a rate of approximately 2 tons per acre. Areas where conventional mulching u not practical due to slope gradients and related equipment safety concerns (> 3H:1~ will either be hytiro-seeded and hydro- mulched or broadcast seeded and protected by erosion control blankets or similar materials. The seed mixtures are comprised primarily of cool-season species, therefore seeding will occur in the fall when these species will benefit from cool fall and eazly winter temperatures and there is typically sufficient moisture for effettive gemtination and initial establishment. The proposed seed mixtures include a number of tree and shrub species and, in combination with natural re-invasion, should be effective in reestablishing both the herbaceous and woody components of the affected plant communities. Reclamation Schedule -The following summarizes the timing of the future final reclamation attivities for the Elk Creek Facilities area, beginning with the decision to abandon the site. Years 1 and 2 - Rema+n~ng stmctures, facilities, and equipment, including associated concrete foundations, will be dismantled, demolished, and either removed from the site or buried on site. Gtlverts will be removed, associated drainage segments will be reestablished, and riprap erosion protection will be placed, where required. Yeaz 3 -Excavations and highwall areas will be backfilled, disturbance areas regraded to the design final postnairtirtg configuration, and postmining drainages constructed. • Year 4 -Available soil material will be replaced on regraded surfaces, surfaces will be prepared for seeding, and reclaimed areas will be seeded in accordance with the approved revegetation plan. It should be noted that mining maybe completed for individual mining areas and these areas may be reclaimed prior to reclamation of the Elk Creek Facilities area since the surface facilities will continue to be used for any ongoing minting. The Elk Creek Facilities will be reckumed as a separate unit following completion of all associated mining actitlties for the entire property. Reclamation Costs - A summary of the estimated cosss for reclaiming the Elk Creek Facilities area is provided in Exhibit 2.03-E3, Instuance andBoi3mg 1 0 . Sanborn Creek Mine Facilities -The Sanborn Creek Mme Facilities include the Sanborn Creek Mine portals, the associated ventilation installation and electrical substation in the portal area, the Sanborn Creek Mine overland conveyor and associated road, the GGulch ventilation installation and Substation No. 3, and several degassification or fire contro]/monitoring boreholes and associated roads. Reclamation plans for the Sanborn Creek Mine facilities are based on cessation of mining from the Sanborn Creek Mme and subsequent closure of the mine, removal of related surface structures and facilities, and reclamation of the associated surface disturbance at some indefinite future date. Demolition and Final Grading -The Sanborn Creek Mme portals will be sealed in accordance with applicable provisions of Rule 4.07 (as shown by the figure, Typical Cross-Section -Mme Seals, in Exhibit 2.05-E5, Reclamation Details). Solid block seals will be constructed a minimum of 25 feet in • PR04 2.05-60 Revised May 2001
