42.04 APPLICATION FOR PERMIT FOR SURFACE OR IINDERGROIIND MINING ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES. <br />2.04.3 General Requirements: Site Description and Land Use Information. <br />(2) (b) (i) (Cont'd.) <br /> <br />• <br />Cerro stony loam, 10-35% slopes. Capability <br />subclass VIIS, nonirrigated. Native_vegetation <br />consists of western wheatgrass, big sagebrush, <br />Gambel oak, serviceberry, pinyon, and juniper. <br />Because of surface stoniness and slope, the <br />soil is unsuited to crops, but is utilized for <br />recreation and livestock and wildlife grazing. <br />Building site development is severe due to the <br />slope, shrink-swell, and low strength charac- <br />teristics of the clayey soil. <br />Orchard Valley West Mine <br />The OV[1M site is very similar to the existing <br />OVM site. Slopes on both sites are moderate to <br />severe and elevations are generally 7200 feet. <br />Soils are stony and well-drained on both sites, <br />vegetation communities are pinyon- juniper and <br />oakbrush types, and land use is predominately <br />for wildlife and livestock grazing. <br />As identified in the SCS, "Soils Survey of <br />Paonia, Colorado", the soils of the OVWM site <br />consist predominately of Delson very stony <br />loam, 20-50% slopes, with smaller areas of Sar- <br />aton-Agua Fria complex, 20-50% slopes and tor- <br />riorthents-rock outcrop-sandstone complex in <br />the lower elevations. <br />Delson very stony loam, 20-60% slopes is in ca- <br />pability sub-class VIIS, non-irrigated. Native <br />vegetation is composed of Gambel oak, service- <br />berry, sagebrush and adapted grasses. Poten- <br />tial vegetation on this soil consists of wheat <br />grasses, blue grasses and needle grasses. <br />Grazing potential is limited for livestock and <br />wildlife. This soil is used for winter range <br />by elk and deer and for recreation purposes. <br />Limitations on building site development are <br />surface stoniness, slope and shrink-swell po- <br />tential, but can be overcome by proper design <br />and construction methods. This soil is also <br />unsuited to crops due to surface stoniness and <br />slope. <br />Revised 10/12/86 <br />Added 10/12/86 <br />Revised 10/01/87 <br />7 <br />
