hydrology of the azea. Temperature extremes at Paonia have ranged from -28 ~F in January to 100 <br />~F during July and August. The average temperature is approximately 49 ~F. Snowfall averages 58 <br />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 azea. <br />A soil survey was conducted on the Blue Ribbon Mine permit azea and adjacent areas on July 29, <br />1981. The field analysis and laboratory data were used to determine soil suitability as a plant growth <br />medium and soil requirements for successful revegetation. <br />Five map units, consisting of three soil series and three miscellaneous types, were identified. The <br />units included Absazokee, Pollard-Torriorthents, Work Clay loams, Disturbed land, and Fluvents. <br />Disturbed land was considered the areas disturbed by mine development. <br />The influence of topography is readily appazent in the development of the soils at the Blue Ribbon <br />Mine. On the east-facing slope to the west of the mine, the soils are generally deep (more than 60 <br />inches) and have clayey subsoils. On the west-facing ridge, those slopes with a more southerly <br />exposure are generally shallow (less than 20 inches) to moderately deep (20 to 40 inches) and aze <br />clayey throughout. On the more northerly exposures on the west-facing ridge, the soils aze <br />moderately deep to deep, and have clayey subsoils. <br />Vegetation -Rule 2.04.10 <br />Specific information regarding collection and analysis of vegetation can be found in Section 2.04.10. <br />Additional information can be found in Exhibit E. <br />Vegetation communities on the Blue Ribbon Mine pemut azea were surveyed on July 29, 1981. Five <br />communities were identified and their distributions aze shown in Exhibit E. The communities aze <br />oak shrub (west aspect and east aspect), mountain mahogany, riparian, and disturbed azeas. These <br />communities are still evident with the exception of the disturbed azea, since the mine is now mostly <br />reclaimed. <br />The west aspect, oak shrub community can be found along the northeastern edge of the permit area. <br />The dominant overstory species is Gambel oak. Grasses were found only in openings in the oak <br />shrub, and were practically nonexistent under the dense stands. The slope of this area vanes from <br />15 to 50 percent, with a west aspect. At the time of the survey it was noted that this community had <br />been extensively grazed, with Indian Ricegrass showing the heaviest signs of use. <br />The Mountain mahogany and Oak shrub cormunity can be found along the southeastern side of the <br />permit azea. The slope vazies from 40 to 70 percent, and has a southwest aspect. Due to the aspect, <br />the vegetation on the southwest-facing slope is not as dense as the oak shrub community with the <br />
