X2.04 APPLICATION FOR PERMIT FOR SURFACE OR IINOERGROUND MINING ACTIVITIES -- MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONFIENTAL RESOURCES. • 2.04.1 Objectives No change. 2.04,2 Responsibilities No change. 2.04.3 General Requirements: Site Description and Land Use Information (1)-(2)(b) No change. (2)(b)(i) As determined by the Soil Conservation Service in the Soil Survey of Paonia Area, Colorado (1981), the area of the rock slope portals is within the margin of the Saraton-Agua Fria complex, 20-50 percent slopes and Torriorthents-Rock outcrop, sandstone complex soil types. Undisturbed and potential productivities of these soils are described as follows: Saraton-Agua Fria complex, 20 to 50 percent slopes. Capability subclass Vlls, nonirrigated. Native vegeta- tion composed of pinyon-juniper, shrubs, and grasses. • Potential vegetation is pinyon-juniper with grass un- derstory. Grazing potential is limited for livestock and wildlife. Browse-grass community provides vital habitat for mule deer. Recreation potential is severe to moderate due to slope, and building site development potential is severe due to slope and surface stoni- ness. Torriorthents-Rock outcrop, sandstone complex. Capa- bility subclass VIIs, nonirrigated. Adapted species consist of wheatgrass and ricegrass. Grazing potential is restricted for livestock. Soils are best suited for wildlife habitat, and used as winter range by mule deer, Recreation potential is moderate due to rock outcrops. Building site development is not rated for these soils, but considered to be severe. These soils are unsuited for cropland due to surface stoniness and slope. (2)(b)(ii)-(4)No change. 2.04.4 Cultural and Historic Resource Information No change. 2.04.5 General Description of Hydrology and Geology • (1)(a) CWI employed the services of Golder Associates to com- • plete geotechnical analyses and design of the rock 3
