Mining Plan <br />J <br />• <br />TOPSOIL REMOVAL <br />Lands containing topsoils: As explained in the Soils Information (Exhibit 1) because very <br />little currently undisturbed land will be disturbed under this plan there is little native soil to be <br />salvaged. The only soil that can be salvaged is located on the southwest side of Area MV. This <br />soil is on a very steep hillside underlain primarily by Saguache Sandstone and Pikes Peak <br />Granite. The soil quality is poor, but whatever can be saved will be saved. The depth of <br />salvage will probably not be more than about 6 inches as the soil structure is very immature with <br />a very indistinct A horizon. However, on the lower slopes of this hillside near the bottom of the <br />valley, the soil may be somewhat deeper. If so, then the salvage will extend to a greater depth, <br />but even there the soil is probably not over one foot in depth. <br />On the north facing slope across the valley the vegetation is primarily forest and the soil <br />is more organic, but depth is similar. Soil from this area will also be salvaged to an approximate <br />depth of six to twelve inches. <br />No other land that will be disturbed in the operation contains native topsoils. Therefore, <br />no other salvage is needed. <br />The volume of soil to be salvaged from these areas is probably about 1500 cubic yards. <br />Soil stockpiling and stockpile protection: Salvaged soil will be stockpiled along with <br />other soils hauled into the site through donation from various construction projects. Much of the <br />soil hauled into the site contains large amounts of woody material that provides excellent <br />protection from erosion. If any soil stockpiles are created that do not have adequate protection <br />by woody material inherent in the soil then the stockpiles will be protected th accordance with <br />the Topsoiling section of the Reclamation Plan (Exhibit F). <br />OVERBURDEN REMOVAL <br />Overburden presence and characteristics: No overburden as such exists over the <br /> <br />limestone to be mined. The limestone deposit extends to the surface and is exposed because of <br />previous mining operations (see Mining History of the Site in this exhibit). <br />Although low grade limestone occasionally is found on top of the higher grade limestone, <br />this low grade limestone is often mined and processed the same as the high grade limestone. <br />This low grade limestone could be considered overburden, but because it is mined, it is not <br />considered overburden. <br />Pikeview Quarry Amendment Exhibit D Page 9 <br />
