Final grading will create a final topography that is appropriate for the final land use. For example, grades on the site will be returned to existing (pre-mining)grade. Topsoil will be uniformly placed and spread on areas disturbed by the mining. The minimum thickness shall be 6 inches above the surrounding finished grade, consistent with existing topsoil depths on-site. The topsoil shall be keyed to the underlying and surrounding material by the use of harrows, rollers or other equipment suitable for the purpose. In those areas where revegetation is part of the reclamation plan, the Operator will revegetate the land in such a manner so as to establish a diverse, effective, and long- lasting vegetative cover that is capable of self-regeneration without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. Seed will be drilled and mulched. The revegetation seeding and plant list on the Reclamation Plan Map contains the preferred species of grasses, shrubs and trees to be planted. Seeding will take place once final grading and replacement of topsoil have been completed. Timing of seeding will be consistent with standard horticultural practice for dryland applications-generally between late September and the middle of April to ensure there is adequate moisture for germination. (e) A plan or schedule indicating how and when reclamation will be implemented. Include: i. An estimate of the periods of time which will be required for the various stages or phases of reclamation. Please refer to the Timetable for Mining and Reclamation in Section (e) of Exhibit D. ii. A description of the size and location of each area to be reclaimed during each phase. Please refer to the Reclamation Plan Map (Exhibit F). iii. Outlining the sequence in which each stage or phase of reclamation will be carried out. Please refer to the Timetable for Mining and Reclamation in Section (e) of Exhibit D. (t) A description of: i. Final grading—maximum anticipated slope gradient or expected ranges thereof; The finished slopes of the reservoir will be 3 horizontal to 1 vertical. Any area reclaimed to native grade will match natural topography. ii. Seeding—types, mixtures, quantities and time of application; Please refer to the Reclamation Plan Map for the list of plant materials and seeds to be utilized. The operator will seed during the appropriate season to ensure adequate moisture for germination and implement weed controls to allow the grasses to successfully BURNCO COLORADO LLC—Tricycle Amendment-Nissen Mine—MLRB 112 Permit Application Exhibit E-4
