horizon depth of about 1.5 to 2.5 inches, with a combined 'N and 'B' horizon depth of about 22 to <br />38 inches. The soil is typically underlain by sandstone. <br />The Persayo soil is a silty clay loam. The Persayo soils located at the Bowie No. 2 site exhibit an <br />'A' horizon of about 1.5 inches deep, with a combined 'A' and 'B' horizon depth of about 18 to 20 <br />inches. The soil is typically underlain by the Mancos Shale. <br />The Torriorthents soil tends to be associated with rock outcrop areas, and the observed texture is <br />silty loam. The site soils exhibit 'A' horizon depths of about I.5 inches. The typical combined 'A' <br />and 'B' horizon depths range from about 6 to 7 inches. <br />The operations approved in Permit Revision No. 3 disturbed an additional 1 1.0 acres, one area <br />located south of Old Highway 133 and the other area located just east of the present mine <br />entrance. Both areas appear to be previously disturbed. The soils present in these disturbed areas <br />are similar to the "Meadow" soil found in other areas of the mine site, as depicted on Map No. 4, <br />"Soils". <br />The soil that was disturbed in the construction of the Freeman Gulch vent shaft, through <br />Technical Revision No. l2, is classified as a Fughes Loam. <br />Vegetation Information - <br />Detailed vegetation information for the Bowie No. 2 permit area is presented in Section 2.04.10 <br />of the permit application document The following summary is derived from the infonnation <br />presented in Section 2.04.10 of the permit document. <br />Three (3) plant communities are present within the main surface operations, facilities and <br />surrounding areas. These communities are referred to as the Juniper Woodland, Mixed Shrub and <br />Disturbed Meadow communities. <br />The Juniper Woodland community exhibits such plant species as Snowberry, Gambel oak and <br />Serviceberry. The Mixed Shrub community exhibits plant species such as Gamble Oak and <br />Serviceberry. The Meadow community is dominated by annual and noxious plant species, such <br />as bindweed, cheatgrass and Japanese brome. Alfalfa and Kentucky Bluegrass are also present. <br />An area of approximately 031 acres is identified as wetland. This area will be disturbed, and this <br />activity will be conducted in compliance with a permit issued by the United States Army Corps <br />of Engineers. The proposed disturbed area was also surveyed for threatened and endangered <br />plant species; however, no such species were found. <br />The Division agrees with the operator's conclusion that the proposed disturbed area is similar to <br />the Lower Meadow Community that exists at the mine site and is shown on Map No. 3, <br />"Vegetation." in the permit application package. <br />A small area was disturbed in the douglas fir vegetation community in the construction of the <br />Freeman Gulch vent shaft. <br />13 <br />
