Mining Life Time Table <br />The expected mine life can be seen below. The life is based on the average production rate. If <br />demand changes, the life expectancy of the pit will change. <br />Mine Life <br />Task Description Expected DuraSon (yr) <br />Mine remaining reserves in orginal pit and pre-mining 0.90 <br />prepazations (Ditches, Berms, Stripping, etc.) for <br />expansion area. <br />Mine Area 1 Phase 1 reclaim previous area. 0.59 <br />Mine Area 1 Phase 2 reclaim previous area 0.58 <br />Mine Area I Phase 3 reclaim previous area. 0.61 <br />Mine Area 1 Phase 4 reclaim previous area. 0.63 <br />Mine Area 2 Phase 1 reclaim previous area. 0.58 <br />Mine Area 2 Phase 2 reclaim previous area. 0.60 <br />Mine Area 2 Phase 3 reclaim previous area. 0.58 <br />Mine Area 2 Phase 4 reclaim previous area. 0.55 <br />Mine Area 3 Phase 1 reclaim previous area 0.98 <br />Mine Area 3 Phase 2 reclaim previous area. 0.87 <br />Mine Area 3 Phase 3 reclaim previous area. 0.93 <br />Mine Area 3 Phase 4 reclaim previous area. 0.98 <br />Mine Area 3 Phase 5 reclaim previous area 0.80 <br />Reclaim final mining area and Staging Area. 0.90 <br />Total 10.2 <br />Garfield County and Enviromental Impacts <br />No significant change of impact is expected from this operation to the County. This <br />amendment is only a new mining area to supply the existing demand supplied from the site. <br />Also, portions of the previous pit will be reclaimed while the initial phase of the expansion is <br />mined. There will be unavoidable visual impacts to I-70. This is due to I-70 being elevated <br />above the site. The pit is wet, therefore dust will be mitigated. All tanks will have secondary <br />containment and discharges are carefully regulated under the CDPHE discharge permit. The <br />final landscape will consist of lakes, wetlands, dryland areas, and cottonwood riperian areas, <br />which will have an excellent appearance from the I-70 corridor and will be an asset for wildlife. <br />4/26/04 Page D-9 <br />
