6.4.4 Exhibit D <br /> Mining Plan <br /> a) This will be a dry mining operation with an aggregate wash plant, and mining methods <br /> will be consistent throughout the life of the mine. The water table here is very deep and <br /> no water will be encountered. Excavation will be performed by powered scrapers <br /> which will remove and haul the raw resource to a processing plant. This processing plant <br /> will move with the mining operation in phases. The scrapers will deposit the material in <br /> a surge pile. A front-end loader will deposit the material from the surge pile into the <br /> crushing and screening plant. After crushing and screening, the products will either be <br /> hauled off site or will be further processed by washing or used in the production of <br /> Portland cement concrete to asphaltic concrete. The finished products will be hauled <br /> off the Penrose pit site on a haul route proceeding on the eastern haul route. The haul <br /> road will enter the Penrose pit site and connect with existing haul roads. The route has a <br /> permitted access point from Colorado Highway 115. The haul route within the site will <br /> be left in place following reclamation for the use of landowners in their ranching <br /> operation. The Colorado Highway 11S access point will also remain at the request of <br /> the landowners. The applicant has a truck scale and office shown on the map. There <br /> may also be stockpiles of materials for retail sales and for severe weather days when <br /> mining areas are not accessible. The applicant also anticipates placing a portable <br /> asphalt batch plant and/ or a concrete batch plant in this area. <br /> b) Excavation will be performed by powered scrapers which will remove and haul the raw <br /> resource to a processing plant. This processing plant will move with the mining <br /> operation in phases. The scrapers will deposit the material in a surge pile. A front-end <br /> loader will deposit the material from the surge pile into the crushing and screening <br /> plant. After crushing and screening, the products will either be hauled off site or will be <br /> further processed by washing or used in the production of Portland cement concrete to <br /> asphaltic concrete. The finished products will be hauled off the Penrose pit site on a <br /> haul route proceeding on the eastern haul route. <br /> c) The water table here is very deep and no water will be encountered. The mining <br /> operation will not disturb the existing hydropic balance of the affected land since <br /> groundwater will not be exposed. Post reclamation will flow toward Eight Mile Creek <br /> and the Arkansas River similar to the present condition. This operation is not expected <br /> to directly affect surface water or ground water systems. The tributary aquifer for <br /> Arkansas River is approximately 40 to 50 feet below the ground elevation. This fact is <br /> evidenced by the lack of springs coming out of the bluff along Eight Mile Creek and <br /> along the Arkansas River where active mining is occurring. During the life of the mine, <br /> the ground water-table will not be encountered. Because of the distance of these wells <br />
