EXHIBIT F (pg 2) <br />efficient and safe manner. The remaining materials (limestone and weathered <br />granite) would be used throughout the entire reclaimed area, as needed. <br />Topsoil salvaged from National Forest System lands will remain on those lands at <br />all times during the mining process. Large quantities of donated topsoil could be <br />used on private lands but not on National Forest System lands. Small quantities <br />of donated topsoil with similar characteristics and materials as the existing topsoil <br />can be used as soil supplementation on National Forest System lands. Castle <br />Concrete will make efforts to screen the donated topsoil to comply with Forest <br />Service requirements. <br />5. Reclamation grading, including slope backfill, topsoil placement, and planting <br />would proceed from the west concurrently with mining (downslope) to the east. <br />Sloped back-walls would be created on each bench with staggered drilling depths. <br />Then, decomposed granite and limestone (if existent) would be used as backfill, <br />which would create a subsoil of approximately one to fifteen feet thick. This <br />subsoil would be stable because granite does not lose strength with moisture and <br />the slope backfill is supported with the stable underlying benches. <br />Excess granite materials removed from national Forest System lands would <br />immediately be moved to the north end of the layback area to begin construction <br />of the northern access road. This activity would continue until that road is <br />completed, most likely within 2 years of the start up. These materials would be <br />removed by bulldozer. <br />The topsoil placed on the disturbed areas would be limited to a maximum <br />thickness of one foot in National Forest System land and two fee[ on private ]and. <br />Average topsoil thickness should be between six inches (the minimum for <br />successful grass establishment) and one foot. With time, some of the topsoil <br />materials are expected to migrate into the underlying backfill materials and <br />improve moisture retention and tree root development. <br />9. Areas covered with topsoil would then be seeded following mechanical <br />roughening of the surface crust, if necessary. Seed would be broadcast by hand. <br />Raking using metal-tined rakes will only be required if the surface is no[ <br />sufficiently loose or if suitable seed to soil contact is not achieved. <br />10. Broadcast seeding would occur preferably within five days of spreading the <br />topsoil in order to reduce the need to mechanically roughen surface crusting. If <br />spreading of topsoil occurs at a time not suitable for seeding, broadcast seeding <br />will occur as soon as the best conditions for seed growth take place. <br />
