Section 3.1.11 Buildings and Structures: <br /> The existing house and outbuilding in the western portion of Cell 4 will be utilized as office <br /> buildings until mining progresses to that portion of the Cell and the buildings are removed. <br /> A portable building will be utilized as an office during Phase 5 and will be placed in the <br /> plant area. <br /> An aggregate processing plant, a 250 by 50-foot sand drying and screening plant and two <br /> 80-foot tall silos will be located at the site for the duration of mining operations. These <br /> structures will be removed and the footprint will be graded back to native grade prior to <br /> final reclamation. The plant structures are shown on Figure C-5. <br /> Conveyors will be constructed at the site to move material from the cells to the processing <br /> plant. The approximate conveyor alignment is shown on Figure C-5. <br /> Section 3.1.12 Signs and Markers: <br /> The Operator will post appropriate signage at the entrance to the mine site. The permit <br /> area will be marked by existing fencing, or proximity to existing County roads. <br /> (d) Plans for topsoil segregation,preservation and replacement;for stabilization, <br /> compaction and grading of spoil,and for revegetation. <br /> Topsoil will be removed and segregated from other spoil. Topsoil not needed for <br /> reclamation may be sold or removed from the site. For reclamation, topsoil will be <br /> replaced by a scraper and generally graded with a blade. Grading shall be done in a <br /> manner that controls erosion and siltation of the affected land and protects areas outside <br /> the affected land from slides and other damage. In addition, backfilling and grading shall <br /> be completed as soon as feasible after the mining process. <br /> Final grading will create a final topography that is appropriate for the final land use. For <br /> example, final grading of the reservoir above the high water line will replace material no <br /> steeper than 3:1 slope to meet the grade at the top of the banks. Topsoil will be uniformly <br /> placed and spread on areas disturbed by the mining, above the anticipated high water line. <br /> The minimum thickness shall be 6 inches above the surrounding finished grade. The <br /> topsoil shall be keyed to the underlying and surrounding material by the use of harrows, <br /> rollers or other equipment suitable for the purpose. <br /> In those areas where revegetation is part of the reclamation plan, the Operator will <br /> revegetate the land in such a manner to establish a diverse, effective, and long-lasting <br /> vegetative cover that is capable of self-regeneration without continued dependence on <br /> irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the <br /> surrounding area. Seed will be drilled and mulched. <br /> The revegetation seeding list on the Reclamation Plan Map contains the preferred species <br /> of grasses to be planted. <br /> Monarch-DENM—Gravel Mine—MLRB 112 Permit Application <br /> Exhibit E-4 <br />
