A description of surface water occurrence and mining impacts on surface water <br />within the permit and adjacent areas can be found in the "Probable Hydrologic <br />Consequences of Hining" section of this document and the "Cumulative Hydrologic <br />Impact Study" document for this mine area. <br />The permit area ie drained primarily by the North Fork of the Gunnison River and <br />two ephemeral tributaries to the North Fork. There are no perennial or <br />intermittent streams on the permit area or adjacent to the permit area. The Fire <br />Mountain Canal intersects all overland flow upstream from the permit area. <br />Production of agricultural products at the Bite ie possible only by irrigation. <br />Geoloav-Rules 2.04.5 and 2.04.6 <br />For a description of the geology, refer to Section 2.04.6 in the permit document. <br />Hap 2 details the Geology/Hydrology within the permit and adjacent areas. <br />The rocks exposed in the vicinity of the permit area are the sandstones and <br />shales of the Upper Cretaceous Meeaverde formation. The structure of the <br />sedimentary rocks in the area dips gently to the east. Localized faults and <br />rolls occur as a result of tectonic activity. Due north of the permit area, the <br />Meeaverde formation contains several sequences of coal bearing rocks. The rocks <br />present in the area of the Terror Creek site are of Hancoe shale formation. <br />Within the North Fork of the Gunnison River Valley, Quaternary Age alluvial <br />deposits are found. A colluvial deposit in excess of 50 feet thick overlies the <br />Mancoe within the permit area and consists of an unconsolidated mixture of large, <br />angular shaped boulders, and rocks and cobbles of various sizes. The <br />unconsolidated material etratigraphically overlies the Hancoe shale in the permit <br />area, and since the early 1900s has been graded to its present surface <br />configuration to allow for irrigated agriculture. The unconsolidated and poorly <br />sorted nature of the colluvial material indicates that it was placed by <br />gravitational mass wasting from the adjacent steep elopes. Some transport by <br />overland flow of surface waters ie also evident. The unconsolidated nature of <br />the material lends itself to deep weathered zones and infiltration of surface <br />water. <br />Climatological Information-Rule 2.04.8 <br />Information on the climate in the area of the Terror Creek Loadout ie detailed <br />in Section 2.04.8 in the permit document. In addition, Exhibit 6 provides data <br />from the weather station in Paonia, Colorado, on average precipitation, <br />temperature, and wind. The wind information was developed for the Weet Elk Mine <br />site. <br />The climate of the region is typical of the Rocky Hountain area. The valley ie <br />semi-arid with annual precipitation averaging about 15 inches per year. The <br />May-September precipitation is 5 inches for the lowlands and 13 inches for the <br />mountain peaks. Temperature extremes at Paonia have ranged from -28°F in January <br />to 100°F during July and August. The average annual temperature is approximately <br />49°F. Snowfall averages 58 inches per year. <br />Soils-Rule 2.04.9 <br />Soil resource information is contained in section 2.04.9 of the permit document. <br />Exhibit 7 contains more detailed information on soils as well ae soil sample <br />cross sections and analyses, which were taken from different areas of the site. <br />The soil samples collected by the applicant has indicated a clay loam soil with <br />poor horizonal development overlying unconsolidated colluvial parent material at <br />an average depth of 11 to 13 inches. The soil mapping units which are present <br />in the permit area consist of Progresso Loam, which is found on slopes of 6 to <br />12 percent and Torriorthents-Haplargids. Review of the soils analyses indicates <br />Terror Creek Loadout Page 4 <br />
