EXHIBIT D MINING PLAN (CONT.) <br />take place. Stockpiles of material will be maintained on the <br />site and, as the need arises, it will be hauled to our project <br />sites. This will be a single stage operation, but the amount of <br />disturbance will be limited to 20 acres or less at any one time. <br />This will allow us to use approximately 5 acres as a processing <br />plant:/stockpile area and approximately 15 acres for the active <br />mining area. As mining progresses around the property the bank <br />slopes will be mined or shaped to the required grades where they <br />are in their final location. This will reduce the amount of work <br />that has to be done to reclaim the site. Reclamation will begin <br />once we have enough area for stockpiled material and the section <br />to be reclaimed will not have to be disturbed again. <br />We do not expect to reach bedrock in this area due to the <br />depth of the gravel and the wish to control the final floor level <br />along the drainage. Review of MAP EXHIBIT C-1 shows how we expect <br />the site to look when mining is approximately 626 done. Note, <br />the floor of the excavation is flat and the slopes into the mined <br />area are 3h to lv where mining is complete on the perimeter. <br />The excess overburden will be used to backfill parts of the <br />exterior slopes. Please note that reclamation is running concur- <br />rent with mining to reduce the amount of disturbance at any one <br />time and that reclamation is following option 1. <br />By limiting the amount of area stripped at any one time we will <br />lessen the visual effects of the mining operation on surrounding <br />area: as much as possible. Please refer to the MINING TIMETABLE on <br />page 11 for the estimated acreage of each area associated with <br />the mining part of this operation. <br />This mine adjoins another mine along the northwest side <br />operated by Mountain Park Concrete (Permit # M-1998-034). We are <br />having discussions with the mine operator to join the floors of <br />the two mines in the future. If this is done each party would <br />mine to their respective property line until the floors meet. <br />This would reduce the amount/of sloping work needed where the <br />mines meet by eliminating the ridgeline between the two mines. <br />We have developed two reclamation plans for this area so in the <br />future we will only need to file a Technical Revision to imple- <br />ment the change. <br />Mining equipment may include but is not limited to, front- <br />end loaders, scrapers, a dragline, bulldozers, dump trucks and a <br />water truck. Processing equipment may include but is not limited <br />to conveyors, crushers and screen plants. A scale and scale <br />house as well as shop and maintenance buildings may also be built <br />at the mine during its life. <br />As much as possible, the surface drainage will be maintained <br />in the same direction as it now exists. The proposed sloping <br />plan for the excavated area should eliminate any concerns of <br />erosion occurring on the site. <br />On a typical operation of this type we may use 2 to 3 ac-ft <br />of water per year. Most of the water used for dust control will <br />be used on haul roads. Please refer to EXHIBIT G - WATER for the <br />discussion of how water will be used at the site and the source <br />of said water. <br />a <br />10 (revised 9/23/09)
