Final grading will create a final topography that is appropriate for the final land use. For example,final grading of the reservoir above the high water line will replace material no steeper than 3:1 slope to meet the grade at the top of the banks. For cells mined at greater than a 3:1 slope, the slopes will be reclaimed at a 4:1 slope to meet existing grade. Topsoil will be uniformly placed and spread on areas disturbed by the mining, above the anticipated high water line. The minimum thickness shall be 6 inches above the surrounding finished grade. 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 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 for each phase. 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. Reclamation for any given stage of mining may take up to five years to allow for successful revegetation. 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. (f) A description of.• i. Final grading-maximum anticipated slope gradient or expected ranges thereof; The finished slopes of the reservoir will be no steeper than 3:1 for slopes mined at a 3:1. If slopes were mined at a steeper slope, the slope will be reclaimed with a 4:1 clay liner. Section 20-Gravel Mine—MLRB 112 Permit Application Exhibit E-5
