Section - 2.05.4 Disturbed areas will broadcast seeded following necessary surface preparation, All dismrbance areas will be broadcast seeded using equipment-mounted or hand broadcast seeders. Seed will be broadcast at the increased rates speciFed 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 is not practical due to slope gradients and related equipment safety concerns (> 3HaU) will either be hydro-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 early winter temperatures and there is typically sufficient moisture for effective germination 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 activities for the Elk Creek Facilities area, beginning with the decision to abandon the site. Years 1 and 2 -Remaining structures, facilities, and equipment, including assouated concrete foundations, will be dismantled, demolished, and either removed from the site or buried on site. Culverts will be removed, associated drainage segments will be reestablished, and riprap erosion protection will be placed, where required. Year 3 -Excavations and highwall areas will be backfilled, disturbance areas regraded to the design final postmining configuration, and postmining drainages constructed. Year 4 -Available soil material will be replaced on regraded surfaces, surfaces will be prepared fox seeding, and reclaimed areas will be seeded in accordance with the approved xevegetation plan. It should be noted that mining may be completed for individual mining aeeas and these areas may be reclaimed prior to reclamation of the Elk Creek Facilities area since the surface facilities will continue to be used fox any ongoing mining. The Elk Creek Facilities will be reclaimed as a sepazate unit following completion of all associated mining activities fox the entire property. Reclamation Costs - A summary of the estimated costs for reclaiming the Elk Creek Facilities area is provided in Exhibit 2.03-E3, Insurance and Bonding Information. Sanborn Creek Mine Facilities -The Sanborn Creek Mine Facilities include the Sanborn Creek Mine portals, the associated ventilation installation and electrical substation in the portal azea, the Sanbom Creek Mine overland conveyor and associated road, the C-Gulch ventilation installation and Substation No. 3, and several degasification or fue control/monitoring boreholes and associated roads. Reclamation plans for the Sanbom Creek Mine facilities are based on cessation of mining from the Sanbom Creek Mine 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 Mine portals will be sealed in accordance with applicable provisions of Rule 4.07 (as shown by the Figure, Typical Cross-Section -Mine Seals, in Exhibit 2.05-E5, Reclamation Details). Seals will be formed and pumped with cementitious foam a minimum of 25 feet in from the portal surface openings. The portal entries will then be backfilled from the seals to the portal openings with soil and broken cock materials and portal and face-up areas backfilled and graded to completely cover all portal structures, establish a stable slope configuration, and eliminate exposed portal face-up areas.
