-8- <br />Vegetation in the general area is limited by the low precipitation. In the <br />southern portion of the Canon City Co al, Field vegetation is predominately a <br />grassland/woodland community dominated by olue grams grass on the gently <br />sloping mesas and ponderosa pine on the hillslopes. In the central portion of <br />the coal field near the proposed mine, the vegetation community is pinon <br />juniper with some blue grams grasslands along drainages. <br />Soils in the general area are relatively thin (less than 1 foot to the top of <br />the C horizon) and alkaline, The soils are derived from the alluvial gravels <br />and from shale and sandstone bedrock. In the permit area, soils are generally <br />of the Louviers-Travessilla complex. The Lou viers soil, a cobbley clay loam, <br />is found on side slopes and the Transsilla soil, a thin sandy loam, is found <br />on canyon rims, ridges and upper sideslopes. As was discussed, most of the <br />area to be used for surface facilities was previously disturbed by surface <br />mining. Therefore, little salvageable topsoil remains. <br />Typical wildlife species associated with the pinyon-juniper in the area to be <br />disturbed are: mule deer, coyote, magpie, red tailed pinon jay, Western blue <br />birds, least chipmunks, Colorado chipmunks and rattle snakes. Changes in the <br />quality and amount of vegetative production due to overgrazing and previous <br />mining have diminished wildlife production, health and species diversity. No <br />threatened or endangered plant or animal species have been observed in the <br />permit or adjacent area. <br />Description of the Operations and Reclamation Plan <br />Twin Pines No. 2 Mine has been planned as a one section, room and pillar <br />underground coal mine. An average annual production rate of 48,000 tons is <br />anticipated. The estimated life of the operation is 14 years; three years to <br />drive the main entries to the south lease boundary and 11 years of retreat <br />room and pillar mining. Because the entries will be driven to the far <br />southern end of the property during the first five year permit term, the five <br />year permit area and the area for the life of the operation coincide. <br />One hundred twenty-seven acres are included within the proposed permit area. <br />The permit area is 127 acres, of which 9.75 acres will be utilized for surface <br />facilities; 95Y of the surface facilities area was previously disturbed. The <br />easement for the existing mine access road is 40 feet wide and 3,456 feet <br />long, consisting of three acres, In addition, the applicant retains the <br />reclamation obligation for four acres at the Twin Pines No. 1 tipple. All <br />areas are shown on the attached Figure 3. <br />As previously discussed, the Twin Pines No. 2 Mine has been designed and <br />located within previously disturbed areas. Only 0,5 acre of undisturbed area <br />will be utilized for the proposed operation. The additional disturbance <br />results from the construction of a ramp and a fill in Lewis Gulch to <br />facilitate a truck loading and a sedimentation structure. Any available <br />topsoil in either undisturbed or disturbed areas will be salvaged prior to <br />construction of the proposed surface operations, <br />
