London Mountain Clean Up July 2025 E-1 Exhibit E Reclamation Plan The reclamation work at the London Mountain Clean Up will be applied to each waste pile disturbed. Map F-1 shows a standardized view of a waste pile in reclaimed conditions. Annual reports to CDRMS will list the areas reclaimed in the prior year, ensuring that the 20-acre limit of disturbed waste piles is not exceeded. Exhibit T Section 1.1.1. details measures taken to preserve vegetation and topsoil for the London Mountain Cleanup. This reclamation plan expands upon that of the approved London Mine 110D, which can be found in Exhibit D of Appendix 1. The associated reclamation maps for the 110D can be found in Exhibit E of that same document. The London Mine 110D area retains all current mining plans without alteration through this application, as documented in Appendix 1. 1. Reclamation Plan All reclamation at the London Mountain Clean Up will be to achieve stable slopes and site conditions for the post mine land use of alpine rangeland or bare rock. Final slopes will be no steeper than what surrounding topography can allow. Typically slopes will be 1.5H:1V or shallower. All stormwater and sediment controls will remain in place until revegetation is successful. Topsoil placement and revegetation will vary depending on the mining environment. Fertilizer may be applied to vegetated areas depending on reclaimed soil conditions. The type, quantity, and schedule of application of fertilizer will be determined in conjunction with the US Forest Service. Any roads built to access waste piles will be reclaimed according to the mining environment that the access road is in. No structures will be installed as part of mining, so none will need to be removed during reclamation. Each mining environments reclamation plan is discussed in more detail below. Topsoil disturbed areas with either stockpiled topsoil from local stripping, or cap with crushed NPAF material processed at the London Mine 110D to an average depth of four inches. Scarify the soil prior to seeding. Revegetate with the Alpine seed mix, as described in Table E-1. Drill seed if possible, broadcast at two times the drill rate if broadcast seeding is required. Cap with crushed NPAF material processed at the London Mine 110D to an average depth of four inches. No revegetation will occur on these areas. Topsoil disturbed areas with either stockpiled topsoil from local stripping, or leave bare to match surrounding bare rock conditions. If topsoiled, revegetate with the Alpine seed mix, as described in Table E-1. Drill seed if possible, broadcast at two times the drill rate if broadcast seeding is required.
