Response: The enclosed Area Map shows the existing features of the proposed expansion area. VICINITY MAP Response: The enclosed Vicinity Map is an excerpt of the Milner, Colorado, 1971 U.S.G.S. quad map, which shows the location of the proposed expansion area in relationship to the Town of Milner and the surrounding areas. EXISTING CONDITIONS MAP Response: A map showing all of the current features currently found on the site is found on Camilletti Milner Pit #2 -Existing Conditions Map. This map shows the locations of all current manmade features such as roads, fences, homes, buildings, etc. found on or immediately adjacent to the property. PHASING PLAN SKETCH/MINE PLAN MAP Response: See attachments. As set forth below in the project narrative, this permit amendment request anticipates modification of the phasing of extraction of materials from Milner Pit #2. Upon completion of extraction of gravel from Mine Block #2 of Pit #2, mining operations would be moved to the proposed expansion area. After removal and stockpiling of topsoil and . overburden, gravel mining will commence. The gravel will be removed down to the shale valley floor bottom and. transported via conveyer belt and/or haul trucks from the extraction area to the current operations area. Processing, including crushing, washing, screening and stockpiling of various products, would remain in the current pit operations area. There would be no change in the existing operations area, with the loading of haul trucks and utilization of the existing access/ haul road in and out of the pit. As discussed below, the amendment requests elimination or relaxation of the condition which limits the maximum disturbed area to 25 acres, so as to allow for a safe and reasonable circulation of it equipment, and adequate space for processing facilities, stockpiles of the multiple materials and circulation of haul trucks in and out of the pit. Mining will proceed in phases of the proposed expansion area as generally shown on the enclosed Mine Plan, with a 50' setback from the south side of Trout Creek. This proposed setback is the same as the setback imposed for the existing pit #2. The expansion area is currently traversed by a gas transmission line contained within a 50' wide easement, which must be either avoided or relocated. The gas line easement is identified on the enclosed Mine Plan. The Applicants have been involved in discussions with Xcel Energy, owners of the gas transmission line. It has not yet been determined whether the gas transmission line will be relocated or whether the line will be avoided, in a similar fashion to the Yampa Valley Electric Association (YVEA) transmission line, which was left in place during the extraction operations in Pit #2. Additionally, there is an existing YVEA power line near the south boundary of the proposed expansion area, as shown on the Mine Plan. The preferred
