EXHIBIT D MINING PLAN (CONT) Road, located west of Highway 85 and in alignment with County Road 20, and running along the south side of Phase 3 in the western parcel . In most cases, existing farm roads will be used that are within the permit area. The initial Plant Site is located on the area north of this access road in Phase 3 . If the elevated conveyor system over HWY 85 is not constructed, a second mine access road may be constructed on the east side near a proposed second Plant Site in Phase 4A when operations begin in that area. The approximate location of both access roads are shown on MAP EXHIBIT C CURRENT CONDITIONS MAP and MAP EXHIBIT C 1 MINING PLAN MAP . At this time, the plan is to install an elevated conveyor system as explained in the original application, from the eastern Phases to the Plant Site in Phase 3 . It will be located in an approximately 400-feet by 1000-feet corridor that crosses the UP Railroad and HWY 85 . The surface of this land is owned by Cannon Land Company. L.G. Everist, Inc, is currently working with the UPRR and CDOT to obtain the necessary agreements and permits to cross the railroad and HWY 85 . The crossing permits will be filed with the Division prior to construction of the conveyor system. The location of this conveyor corridor is shown on all Map Exhibits, and the 7 . 90 acres is included in the Phase 3 total acres . The access roads used in the mine site will be constructed of gravel from the site. They will be an average of 30 feet wide and graded to allow for drainage and have ditches as necessary to collect runoff. Any runoff from the road will be retained on site and allowed to soak into the ground or evaporate. The access roads will be maintained as needed. Reservoir access roads will be built around each reservoir to provide access for the owners . The reservoir access roads will remain when reclamation ends as they will be used to access and maintain the property. GEOLOGIC SETTING The affected lands are located along the South Platte River in a Quaternary age, Piney Creek alluvial deposit . The eastward dipping beds of upper Cretaceous age are overlain at an angular unconformity, by the Piney Creek alluvium. The sand and gravel encountered in the Piney Creek alluvium are a result of water erosion and redisposition of rock materials from the Front Range of the Rocky Mountains . The deposition of this material occurred during a time when the river was much larger than it is now. But, judging from the scarcity of large rocks found at the L.G. Everist, Inc.
