• Cultural and Historic Resources -Rules 2.04.4 and 2.05.6(4) and2.07.6(2)(el <br />Information regarding the cultural and historic resources of the permit area are in Section <br />2.04.4 of the Bear No. 1 and 2 permit application, and in Section 2.04.4, and Exhibits 6 <br />and 7 of the Bear No. 3 permit revision application. <br />No known cultural or historic resources that are listed or are eligible to be listed on the <br />National Register of Historic Places exist within the life-of-mine permit area or in areas to <br />be affected by mining. This determination has been made through examination of files of <br />the Colorado Historical Preservation Office, the Colorado State Archaeological Office, the <br />Colorado Office of the Bureau of Land Management, the State Historical Preservation <br />Office and the National Register. The Colorado Historic Preservation Office was contacted <br />by the Division at the initiation of this renewal process. <br />Results of a March 1977 archaeological survey of the permit area are presented in <br />Exhibit 7. No archeological resources were discovered. <br />The Colorado State Historic Preservation Office confirmed in a letter dated <br />December 13, 1993, that the Permit Revision No. 1 activities will not impact any cultural <br />resources due to the lack of any such resources in the area. <br />No public park or national historic place will be adversely affected by the Bear mining <br />operation; therefore, a damage mitigation plan is not required per Rule 2.05.6(41. <br />• Climatolooical Information and Air Resources -Rules 2.04.8. 2.05.4(2)(hl <br />Climatological and air resource information is contained in Sections 2.04.8 and 2.05.6 of <br />the Bear No. 1 and 2 permit application, and in Sections 2.03.10, 2.04.8 and 2.05.6 and <br />4.1 6 of the Bear No. 3 permit revision application. <br />Local temperature is inversely related to elevation. Mean annual temperatures along the <br />mountain peaks are much colder than the mean annual temperatures of adjacent valleys. <br />The mean annual temperature of Paonia, Colorado is approximately 50~F. Temperature <br />extremes recorded at Paonia are -28~F (January 1913) and 100~F (June 1927; July and <br />August 1934). <br />Precipitation is directly related to elevation. The valley in which Paonia and Somerset are <br />situated is semi-arid with average annual precipitation of 15 inches. Mean annual <br />precipitation increases with elevation, approaching 40 inches per year on the summit of <br />Mt. Gunnison. Annual snowfall on mountain peaks south of Somerset, Colorado, is <br />greater than 300 inches. Average annual snowfall at Paonia, Colorado, is approximately <br />58 inches. The May to September precipitation is five inches for the lowlands, and 13 <br />inches for the nearby mountain peaks. The remaining majority of precipitation occurs <br />during the months of October to April. <br />Average annual precipitation at Somerset, Colorado, is twenty-five inches (Figure 2). <br />Information from the West Elk Mine permit application indicates that approximately <br />• two-thirds of the annual precipitation occurs between October and April of each year. The <br />remainder of the precipitation occurs between the months of May and September. The <br />5 <br />
