disconformably over fine-grained sedimentary units. The underlying bedrock is Mancos shale. The <br />bedrock slope is basically flat. <br />4. Soil Salvaee <br />Topsoil will be stripped and stockpiled for use in reclamation. The depth of the surface soil <br />suitable for use in reclamation, and wrresponding depth to be stripped, depends on location on site <br />but generally ranges from about four to 12 inches (weighted average of about seven inches). <br />Map C-2 included in the appendix illustrates the anticipated locations of topsoil stockpiles. <br />All stockpiling will occur neaz the perimeter of the affected azea. As a stabilization measure, soil <br />stockpiled for longer than one yeaz will be seeded with a perennial sod-forming grass such as <br />western wheatgrass. Additional information regazding the site's soil resources is provided in <br />Exhibit I -Soils information. <br />Ground water occurs at a relatively shallow depth and the majority of the affected azea will <br />became open water. Sufficient topsoil will be salvaged for reclamation purposes but excess soil <br />will be sold. <br />5. Mining Plan <br />It is planned that operations will begin on the northeast side of the site and work toward the <br />south and west. Ground water is encountered at a depth of about three to four feet below the ground <br />surface. Up to 2006, the aggregate was wet mined using an excavator on the bank of the pit. From <br />2006 to the end of the life of the pit, the gravel will be mined by dozer and front end loader <br />operating in a dry pit utilizing a water pump. It is expected that the pump will flow approximately <br />2500 gallons per minute when the pit is neaz the bottom. The water will be pumped into a small <br />settling pond which will then release the water into a ditch which runs east to the River in a short <br />distance. Raw product stockpiles will be created in the pit and a loader will load the raw gravel into <br />North R-34 Pit I/o7 <br />
