tanks will be located in the processing area. Several hazardous materials will be stored and used <br /> onsite throughout the project. These materials include products that are associated with diesel <br /> motors and products associated with asphalt and concrete production. <br /> No night mining activity is scheduled for the operation; however, portable lighting may be used <br /> within the pit from time to time. Portable lights will only be used for the purpose of equipment <br /> maintenance activities within permitted hours in the winter months while the days are shorter. <br /> Portable toilets will be used for employees. Mining structures such as the scale house, fueling <br /> area, and office trailer,will be portable and will be located within the processing area. Structures <br /> such as the asphalt plant, concrete plant, and crushing and screening equipment will also be <br /> portable and will move throughout the site, as needed. <br /> Existing 4-strand barbed wire fences border parts of the western edge of the site parallel to the <br /> Union Pacific and Burlington Northern Santa Fe railroad tracks. The southern extent of the site is <br /> boarded by barbed wire fences separating Edmundson Ranch lands from neighboring parcels. <br /> The Operator commits to clearly marking the permit boundary in areas that do not have fences. <br /> Speed limits and other traffic control signs will be found throughout the site and around the <br /> operation area. No problems are expected with vandalism. <br /> The site will use existing on site roads located on Edmundson Ranch land, see Map C-3.No new <br /> roads will be created through the Colorado State Land Board property with the exception of <br /> temporary tracks used to transport blasted material to the processing area. Unimproved roads on <br /> State Land Board and Edmundson Ranch lands are detailed on Figure 6, Figure 7, and in Table <br /> D-2. The gravel haul road exists solely on Edmundson Ranch land until it joins County Road <br /> 120 as shown on Map C-3. To facilitate drainage across the ROW, 18" corrugated metal pipe <br /> culverts will be installed at a spacing of every 1,000 horizontal feet. Multiple fences are crossed <br /> and gates are shown on Map C-3. After turning south on County Road 120, haul trucks will join <br /> CO-10 to Highway 25 for transport north and south or will enter the town of Walsenburg to <br /> access US-160 to transport material to the west. The Edmundson Ranch land road is an <br /> unimproved road that will be graveled prior to hauling; County Road 120 is a gravel road <br /> without shoulders; and CO-10 and US-160 are paved roads without shoulders.No sidewalks are <br /> Bradford Mesa Quarry „� .,., •. ,.�rt_ <br /> January 2020 D-15 <br />
