MINING PLAN EXHIBIT D(CONT) The PRE-MINING MAP-EXHIBIT C shows how the area looks at this time. The gravel deposit is an alluvial deposit that averages 15 to 45 feet deep across the property. This deposit will tend to thin as mining progresses from east to west and moves into the lower level . The deepest area is under the terrace area on the east . The numerous buildings and structures located on the site at this time will be demolished and hauled from the site prior to mining commencing. This includes any buried gas, phone and water lines on the site . The operator will contact a buried line location service to check the area for any type of buried utility or gasline that are not owned by the landowners and need to be left when mining is complete. MAP EXHIBIT C shows the outline of the mining area, the touching landowners, the 200 foot ownership, current topography, and hydrologic features of the property. The land is presently used for rural residential and agricultural purposes by the landowners . Most of the area is highly disturbed where equipment has been stored or used for various agricultural activities . Most of the area would be considered poor range land or pasture. There has been little or no maintenance of the site for many years . It is overgrown by invading weeds and contains little natural vegetation except around the old gravel mine lake. Cottonwood, Elm and Russian Olive trees have invaded the area on the lower terrace and western area that have shallow ground water. The Russian Olive trees will be removed during mining and any other trees outside the area to be disturbed will remain. Access to the site is via 2 existing driveways; one from the Monaco Street on the east side and the other down a shared private lane from East 88th Ave. , on the southwest part of the property. The driveways will be widened and maintained as needed and will remain when mining is complete . Since the lanes are an existing private road that will remain when reclamation ends, they are not included as part of the permit area. 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 Pine Creek alluvium. The sand and gravel encountered in the Piney Creek alluvium are a result of water 4(Revised 12/15/2014)
