MINING PLAN EXHIBIT C <br /> we will use the upper 25 feet of material. when mining ends the <br /> floor will be leveled and reseeded using the seedmix shown in the <br /> vegetation information on page 5 . <br /> We expect to remove the upper 25 feet of the deposit. This <br /> site has three layers of material. The upper layer is 8 to 12 <br /> inches of topsoil; the second layer is a 24 to 45 inch thick <br /> layer of whitish clay suitable for pond lining material and the <br /> last is a deep deposit of silty gravely sand that is usable for <br /> dressing roads and as structural fill. o.,z <br /> As noted in the soils and vegetation section there 1-9,_8 to <br /> 12 inches of very sandy topsoil on the site. When encountered it <br /> will be stripped and stockpiled around the perimeter of on the <br /> floor of the site for use in reclamation. If the soil stockpiles <br /> remain undisturbed for more than one growing season� a cover crop✓ <br /> of Western Wheatgrass will be planted at a rate of 3 .0 pls/200 <br /> Ft2. <br /> The entrance to this site will be from an existing road used <br /> for internal access between the irrigated fieldy This road is <br /> our primary access to this field and it will remain when mining <br /> is complete. The northern part of this road is not included in <br /> the permit because it is an existing road that will remain when <br /> reclamation is complete. Periodic grading will be necessary to <br /> keep the road in its present condition and to make it passable. <br /> On-site equipment may include, but is not limited toe a <br /> motor grader, front-end loaders, motor scrapers, a dozer, convey- <br /> ors, a screening plant, dump trucks and a water truck. Final <br /> processing may be done offsite depending on the need at a partic- <br /> ular project site. <br /> Little or no water will be used at the site. This material <br /> is very sandy and we do not plan to wash it. If dust control <br /> water is use it will be obtained from sources we have available <br /> and approved for that use. <br /> 9 <br />
