County Road No. 27. Detailed discussion concerning Alluvial Valley Floors can be found in Section B, part XVII of this document. Technical revision 14 (TR-14) approved the undermining and subsequent subsidence of a small portion of Fish Creek between the Fish Creek borehole facility and County Road No. 27. The operator presented information predicting no adverse impacts to the alluvial valley floor would be realized. Rigorous monitoring was established and conducted to verify the accuracy of this prediction. Details discussing the results of this experiment can be found in section B, part XVII of this document as well as in Exhibit 7j of the permit application. The climate within .the azea is semi-arid with an annual precipitation of 14.6 inches. Approximately 45 percent of this precipitation occurs during the growing season of April though September. High temperatures generally range from 70-80~F in the summer months to below freezing in the winter months. Normally, a significant snowpack resides on the ground for 4-5 months during the winter. Two broadly classified soil complexes exist within the permit area. These are Typic Paleoborolls - Borollic Camborthids and Argic Cryoborolls - Cryic Paleoborolls. All soils except for approximately three acres have already been disturbed by surface mining. However, prior to mining, the Typic Paleoborolls - Borollic Camborrhids soils covered the disturbed area. They occur primarily on uplands and are formed in materials weathered in place from soft shale. These clayey soils are moderately deep to deep, well drained and usually contain less than 35 percent rock fragments. Permeability is slow, shrink-swell potential is high and potential frost action is moderate to high. These soils aze used for rangeland, non-irrigated cropland, and irrigated hay and pastureland. Vegetation in the vicinity of the mine is characterized by four major communities: grassland, mountain shrub, big sagebrush, and cropland; and by two sub-types: aspen and mountain shrub-rock outcrop. Within the Foide] Creek Mine disturbed area, the prominent vegetation types prior to disturbance were big sagebrush and cropland (dryland small grains). Numerous wildlife species inhabit the general area. The most predominant are elk, mule deer and grouse. Other wildlife species include: black bear, cougar, rabbit, coyote, bobcat, red fox, rodents, bats, skunks, waterfowl, amphibians and reptiles. Two golden eagle nests are located on sandstone cliffs adjacent to the disturbed area within the permit boundary for CYCC Permit No. C-81-071. There is critical winter habitat for elk, an elk migration corridor and elk calving grounds and critical sage grouse habitat within and adjacent to the proposed permit area. Sage grouse critical habitat is located outside of the disturbed area. Cultural and historic resources within the permit azea include three historic sites and one prehistoric or protohistoric site. Two of the historic sites are undistinguished homesteads with no important architectural features and which are not associated with persons important in history. The other historic site, the Foidel Canyon Schoolhouse, is listed in the National Register of Historic Places, and is located in the general area of the main facilities along Foidel Creek. It will not be undermined or subsided and is protected appropriately. The prehistoric site (SRT345) is a rock art site located on the outcrop of the Twentymile Sandstone directly north of the main mine facility area. Mining approved under PR-02 (Southwest Mining District) undermined and subsided SRT345. Stipulation No. 33 was attached to the PR-02 approval and the required appropriate 6
