Section 2.04.8 Climatological Information <br />• (1) A statement of the climatological factors that are representative <br />of the proposed permit area. <br />The Red Canyon #1 Mine and proposed #2 Mine site lie on the <br />southern slope of Grand Mesa in a small box canyon about 3-1/2 <br />miles northwest of the town of Cedaredge, Colorado. No detailed <br />information is available for the mine site. The closest station <br />to the mine site is the town of Cedaredge, elevation 6,200'. <br />Refer to Drawing 2.04.3(2)(b)(i)-1 and to Drawing 2.04.8(1)-1. <br />(a) The mean monthly precipitation. <br />For the period 1951 through 1973 the town of Cedaredge, Colorado <br />averaged 0.99 inches of precipitation per month, or approximately <br />12 inches per year. October had the greatest average precipita- <br />tion of 1.40 inches. February had the least average precipitation <br />of 0.77 inches. This information can be found on Tables 2.04.8 <br />• (1)(a)-1 and 2.04.8(1)(a)-3. Information for December 1981 to <br />November 1983 is included in Table 2.04.8(1)(a)-9. <br />(b) The average direction and velocity of the prevailing winds. <br />As noted above, there is no wind monitoring station in the Red <br />Canyon #1, Mine and proposed #2 Mine or in the town of Cedaredge. <br />The closest station is in Grand Junction, Colorado. Refer to <br />Drawing 2.04.8(1)-1. The data, therefore, cannot be official for <br />the mine site area. <br />Information obtained from Grand Junction on prevailing wind, in the <br />Red Canyon #1 Mine and proposed #2 Mine site is as as follows: <br />1. Average wind direction is from the north. <br />2. Average wind velocity is light, about five to six~MPH. As <br />stated before, a more local source is not available for wind <br />• patterns at the mine site. <br />REVISED January 13, 1984 65 <br />
