EXHIBIT D <br /> MINING PLAN AND TIMETABLE <br /> LOCATION <br /> This is an open pit mine located about 0 . 75 miles south of Fort <br /> Lupton, Colorado, with the primary entrance on the east side of <br /> State Highway 85 approximately 1 . 8 miles north of WCR 6 at the <br /> west end of WCR 8 . 5 . The coordinates of the west entrance are <br /> 40003119. 407411, -104049108 . 8772" . A second entrance can be used <br /> to reach the mine from the HWY 85 and HWY 52 exit (Ft . Lupton) , <br /> go east 0 . 6 mile to Denver Street then south on South Denver St . <br /> 2 . 0 miles to WCR 8 . 5 then west on WCR 8 . 5, 0 .26 mile to the <br /> entrance. Please refer to EXHIBITB-VICINITY MAP for the property <br /> configuration and the relationships to surrounding geological <br /> features . The area to be mined lies north of this point on the <br /> east of side of HWY 85 . <br /> GENERAL INFORMATION <br /> The primary commodities to be mined are sand, gravel, topsoil, <br /> overburden, and borrow materials . No incidental commodities will <br /> be produced at this mine. The mine will be operated as a Single <br /> Stage with the maximum allowed disturbance not to exceed 45.46 <br /> acres . The area will be backfilled as mining progress from south <br /> to north. <br /> The area is made up of 3 use areas at the current time. Most <br /> of the property is an irrigated agriculture field used for gen- <br /> eral crop production, the southern area has been used histori- <br /> cally as a farm yard where equipment has been stored. The final <br /> area is the road corridor along the southwest side that slopes <br /> from the field to the neighbors pond. <br /> As mining progresses north, backfilling will begin once enough <br /> area is open so the two activities do not interfere with each <br /> other. Only clean Inert Material will be imported for use as <br /> backfill. <br /> The area being permitted and much of the surrounding areas have <br /> historically been used as irrigated crop land, vacant land and a <br /> small rural residential area. Immediately south of this site is <br /> a Denver Water Board reservoir (M-2004-078) and to the southwest <br /> is an Asphalt Specialties Mine, M-2015-030 . Both mines are still <br /> active so mining is compatible with the neighborhood. This site <br /> lies east of the South Platte River, east of HWY 85 on a terrace <br /> deposit containing an alluvial gravel deposit of commercial <br /> quality. Mining will stay 2 feet above the groundwater table. <br /> Once mining gets close to the elevation of the pond on the south, <br /> 8 1/2 Enterprises LLC.
