Support equipment will to come to the site on an as- needed basis. The 3.67 acre area will house the mine office, the shop, parts storage and a truck scale. There will be no blasting as part of this operation. No refuse, acid or toxic producing materials are expected to be encountered in this operation. If these materials are encountered, topsoil will be placed over the area and mining will move to a different area. The stormwater containment berms are intended to hold the stormwater for less than 24 hours. This will be done by storing the water on the pit floor. The stormwater will infiltrate to the groundwater as it did prior to mining. All existing fencing will stay in place. Any new fencing will be installed according to the Division of Parks and Wildlife's specifications. The operator commits to clearly marking the permit boundary with stakes surveyed on site. It is planned that the material may be used to provide base material for construction projects in the area. One main road will be present in the mining area and will change locations in the pit as mining progresses. This road will access Mining Area 1, which also is accessed by the new access road. In pit roads are not delineated as they will move throughout mining. 4. Topsoil, Overburden Handling Topsoil will be salvaged from all Mining Areas as well as the reclaimed slope that needs to be re- disturbed. Topsoil from Mining Area 1 will be stockpiled in Topsoil Stockpile 1 located in the southwest portion of the permit area. All other topsoil will be directly replaced. Overburden encountered during mining will be placed on the pit floor of previously excavated areas. The expected average topsoil thickness available for salvage is approximately 12 inches with a stripping range of 6 -18 inches. The topsoil stockpile will be seeded with the rangeland seed mix shown in Exhibit E. Uncompahgre Pit, February 2013 D -6
