<br />the Blue Ribbon Mine. <br />The disturbed area .associated with the Blue Ribbon Mine is approximately 20 acres, or about 0.1 percent ofthe <br />drainage area of Hubbard Creek, excluding those areas of upstream diversion. Since the mine workings are <br />above the level of Hubbard Creek, the mine presently does not experience any inflows which can be directly <br />related to water flowing in Hubbard Creek. <br />A spring survey of'the permit area has been completed and one spring was located. This spring is located <br />below the mine bench and discharges from rock strata which are stratigraphically below the E seam. <br />A small ephemeral drainage enters Hubbard Creek from the east near the northeast corner of the permit area. It <br />flows only during spring runoff. The gradient of the channel is 28 percent. <br />Geology -Rules 2.04.5 and 2.04.6 <br />For a description of'the geology of the area, please refer to the "Probable Hydrologic Consequence" section of <br />this document. <br />The geology sections in the permit application can be found in Section 2.04.6 and in Exhibit R. <br />Climatological Information -Rule 2.04.8 <br />The climatological information in the permit application can be found in Section 2.04.8. <br />The Wilcox Ranch Station is the climatic data station closest to the Blue Ribbon Mine. This station is <br />approximately three miles southeast of the Blue Ribbon Mine, just east of Bowie, on the north side of the <br />North Fork of the Gunnison River. <br />At Paonia, the climate is semi-arid with annual precipitation averaging about 15 inches per year. Mean annual <br />precipitation increases with elevation, reaching over 40 inches per year near the summit of Crater Peak. The <br />May-September pre;capitation is 5 inches for the lowlands and 13 inches for the mountain peaks. 'T'his indicates <br />that snowfall patterns play an important part in determining the hydrology ofthe area. Temperature extremes at <br />Paonia have ranged from -28 ~F in January to 100 ~F during July and August. The average temperature is <br />approximately 49 ~l?. Snowfall averages 58 inches per year. <br />Soils -Rules 2.04.9 <br />Information on Soil Resources can be found in the permit application in Section 2.04.9. Additional <br />information can be found in Exhibit D, which is a map of the soils on and adjacent to the permit area. <br />A soil survey was conducted on the Blue Ribbon Mine permit area and adjacent areas on July 29, 1981. The <br />field analysis and laboratory data were used to determine soil suitability as a plant growth medium and soil <br />requirements for successful revegetation. <br />Five map units, consisting of three soil series and three miscellaneous types, were identified. The units <br />
