2.04.8(1)(a) <br />Precipitation patterns are not obvious for the area. Percipitation <br />• has been lowest between May and November, especially between June <br />and October; yet considerable precipitation has fallen during <br />each of these months in one year or another. All months but <br />November have received more than two inches at least in some <br />years. Precipitation during April and June is most variable; <br />the range between their maximum and minimum values (U.S. Deparment <br />of Commerce, N.O.A.A. Environmental Data Service.) <br />(b) Average direction and velocity of prevailing winds. There <br />are no meteorological monitoring stations and therefore, no <br />data accumulation for the area of the Bear r^.ine. Because of <br />the extreme topographical influence on the wind flows over <br />the area of the Bear i4ine the direction of the prevailing wind <br />varies with the time of the day. The direction in the morning <br />is basically southeast. The afternoon is northwest. The <br />evening is again southeast. Refer to Figures 2.04.8(1)(b)-1, <br />2.04.8(1)(b)-2 and 2.04.8(1)(b)-3 for wind roses recorded by ARCO. <br />• <br />Information presented below was obtained by ARCC at three (3) <br />sites established within one-quarter mile of the Bear Mine. <br />Data is for the Period March 1, 1977 through August 31, 1977, and <br />is presented in Table 2.04.8(1)(b). <br />(c) Mean Monthly Temperature. <br />Table 2.04.8(1)(c) below shows the temperature data collected <br />as part of the ARCO program referred to in (1)(b) above. <br />As data is accumulated and becomes available, the data will be <br />presented to the D1LR Board for attachment to the file containing <br />this application. <br />Section 2.04.9 Soils Resource Information <br />• (1) This is an underground mine. Refer to Drawing 2.04.3(2)(a)-1, <br />Existing Land Use, to determine the extent of surface disturbance. <br />The total disturbed area is approximately 19.3 acres. <br />5-63 <br />
