MINING PLAN EXHIBIT D <br />1. General Mining Plan <br />The permit area will be staked prior to any additional site disturbance. Map C -2A shows the <br />configuration of the site after mining has progressed through mining Area 4. This map also <br />displays the visual buffer berm left as Mining Area 5. Map C -2B shows the configuration of the <br />fully mined out pit as well as the location of the processing plants, stockpiles and office /shop <br />area. The plan shows that mining will be done in 5 phases: Mining Areas 1 through 5. Mining <br />Areas 1 through 4 contain the majority of the gravel resource and Mining Area 5 is used to retain <br />the visual buffer to the end of mining. Processing of the gravel will be conducted within Mining <br />Area 1 as shown on Map C -2B. The gravel will be excavated and hauled to the crusher with a <br />loader. Mining will progress in order starting in Mining Area and finishing in Mining Area 5. <br />Access to the mining area will be from a new access road starting at T Road immediately west of <br />the Horsefly Creek bridge crossing. Originally, it was contemplated to use T Road to access the <br />pit area, but a few houses are very close to the road, so therefore, Rocky Mountain decided to <br />move the access 100 feet south of T Road. This new access slightly disrupts the irrigated field, <br />but it provides better mitigation for the homes along T Road. In addition to constructing this new <br />access, the operator commits to constructing a permanent berm of 6 feet height, with slight <br />undulations immediately north of the access road to protect the residences from noise, dust and <br />visual impact from the truck traffic on the road. The berm will be topsoiled with at least 8 -12 <br />inches of topsoil and seeded and mulched using the dryland range mix described later in this <br />reclamation plan. This access road will cross the Montrose West Canal with a new crossing, and <br />will then traverse up the side of the terrace and end in Mining area 1. This access road is shown <br />on Map C -2A. The access road will be approximately 24 feet wide travel surface with a small v- <br />shaped drainage ditch on any cut slope of approximately 1.0 feet depth. The entire access road <br />will be paved with recycled asphalt to a depth of 4 inches, underlain by 2 inches of Class 6 road <br />base, underlain by 18 inches of pit run gravel. The crossing of the Montrose West Canal will be <br />in a new small bridge, which is the same size as all other crossings of the Canal in the <br />surrounding area. This bridge will be designed by an experienced professional engineer <br />acceptable to Montrose County Engineering Department. The design will also be approved by <br />Uncompahgre Pit, February 2013 D -1 <br />
