• will occur in this 30 foot buffer zone. Topsoil stockpiles will be clearly labeled with signs to avoid any disturbance prior to use for reclamation. Long term topsoil stockpiles that will remain for more than 2 years will be graded and quick seeded to minimize erosion. All topsoil stockpiles will be inspected for erosion and maintained as needed. Proposed topsoil stockpiles are located on the mining plan map. Mining equipment will then be moved into the area to commence the mining process. The sand and gravel will be mined utilizing scrapers, bulldozers, loaders and graders. Mining will occur only within the delineated 5 acre (or less) area and in areas where topsoil has been removed. In most areas excavation will not exceed 25 or 30 feet. In some areas, however, material will be removed to depths up to 40 or 50 feet. In areas where the m~ning excavation will be over 10 feet, mining will occur in lifts and the mining highwall will be benched or sloped as • necessary to maintain a geotechnically stable configuration. once removed, the material will be transported to a screen deck located within the permit boundary for processing. The usable screened materials will be separately stockpiled from the unusable materials, such as fines or larger diameter rocks. Usable material will transported from the stockpile as necessary. Material stockpile locations will vary from time to time within the permit area, depending on which areas are being mined and concurrently reclaimed. Once an area has been graded and reseeded for final reclamation, it will not be used for mining, screening, or stockpiling. The major drainages in the area will not be disturbed. These are small ephemeral drainages that run only during snowmelt or storm events. Any runoff into the excavation pit area will be contained in the pit. Silt fences or straw bales will be • installed to control sediment from any uncontained runoff. An existing gravel access road to the site will be utilized.
