EXHIBIT D MINING PLAN (CONT) County roads (22 & 22 . 5) are adjacent to the eastern area. The eastern area also has oil and gas facilities, which include four (4) oil/gas wells, three (3) of which are shut-in. "Shut-in wells" is "A well which is capable of producing but is not presently producing. " They are usually plugged and abandoned completely by the oil/gas company at some time in the future . The Platteville Ditch runs along the east side of the east parcel . MAP EXHIBIT C-CURRENT CONDITIONS MAP, shows the outline of the Affected Lands/permit area, the adjacent landowners within 200 feet of the facility, current topography, hydrologic and surface features of the property. Of particular note, the western permit/affected lands line is established one-hundred (100) feet east and parallel to the east toe of the berm built by the landowners along the South Platte River and/or historical levees built by the US Army Corps of Engineers along the South Platte. Over the years, it appears this bank has been lined with armoring materials along its entire length by multiple landowners . No mining will take place within a minimum of 150 feet from the river bank that exists at this time . Mining will be done at a slope of 3-height (3h) to 1-vertical (lv) from ground surface to the floor of the mine inside each reservoir. The initial access to the site is via an existing Private 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 will be located on the area north of this access road. A second mine access road may be constructed on the east side near the eastern Plant Site in Phase 4A when operations begin in that area . The approximate location of both access roads are shown on MAP EXHIBIT C-1 - MINING PLAN MAP and MAP EXHIBIT C -CURRENT CONDITIONS MAP. In the future a conveyor crossing from the eastern area to the western area may need to be constructed. This would only happen if L.G. Everist, Inc . were to obtain the necessary permits to cross Highway 85 and the UPRR with a conveyor. Should this happen, an amendment will be filed with the Division that would include the, Source of Legal Rights to Enter, crossing permits and show the location and design details for the crossings . The access roads will be constructed of gravel from the site . They will be at least 40 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 road will be maintained as needed. Maintenance roads will be built around each reservoir to provide access for the owners . The access roads will remain when reclamation ends as they will be used to access 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 L.G. Everist, Inc- Ragsdale Reservoirs June 11, 2020 D-2
