• -19- • <br />Piezo~netric contours indicate that the overburden is of low permeability <br />however it appears as thouylr the reclaimed spoils may increase <br />permeability. This would indicate that the mine has the potential to <br />increase recharge rates. Curren[ monitoring of spoils will aid in <br />verifying this prediction. <br />Pump tests of the overburden reveal trans~nissibilities of 514 gal, per <br />day with storage coefficients of 2,12x10 4 (theis). This data <br />indicates that water availability from shallow hedrock aquifers is small <br />and could not be expected to yield large amounts of water for sustained <br />periods. <br />Water quality analysis of the shallow bedrock aquifers indicate it to be <br />of the calcium, magnesium-sulfate type. The content of sulfates, iron, <br />magnesium and dissolved solids make it unsuitable fur drinking water <br />purposes. This indicates that the water has been in the aquifer a long <br />time and .therefore ground water movement is slow. Un this basis it does <br />not appear that local ground water resources are significant. The mine <br />may be benefiting local ground water conditions by increasing recharge <br />which would tend to dilute the poor quality yround water. future <br />monitoring data should verify this prediction. <br />Based on the applicant's statement of probable hydrologic consequences <br />the Division finds that the proposed operation will not cause material <br />damage outside the permit area. <br />IX. Climatological/Information and Air Resources (2.U4.f3 <br />n n[ n o ti n ] ~ <br />Climatological information is found in tab 8 of the permit appilcation. <br />The climate of proposed permit area is typical of continental <br />intermountain regions. Typically the area experiences cold winters, hot <br />summers, low rainfall and short growing seasons. The Nucla area receives <br />approximately 12" of precipitation which primarily falls between October <br />and May. Predominate winds in the area are from the southwest. The <br />applicant has supplied the information required by these sections. <br />in a discussion with Barry Andrews of the Air Pollution Control Division, <br />it was confirmed that the Nucla f4ine does not need an Emissions Permit. <br />This is based on the fact that Equipment installed at the mine prior to <br />February 1, 1972 which has not been moved is qualified to be <br />grandfathered from Emissions permitting. <br />X.
