_'~ _ <br /> <br />1. Underground development waste will be deposited <br />into worked-out pillar areas or in other permitted <br />areas. <br />2. The dip of the strata and the mine workings is away , <br />from Trout Creek; and <br />3. Over 817 of the mine workings are above the <br />piezometric surface. <br />Therefore, the Division concludes that there will be no adverse effects <br />from the mininy operation due to leachate development from waste <br />material, mine drainage, or dewatering the alluvial aquifer. <br />A cumulative hydrologic assessment of effects of coal mining on the Yampa <br />River Basin was prepared for the Division by the consulting firm of Kaman <br />Tempo. The report stated, "The Apex No. 2 Mine appears to have <br />negligible off-site impacts to the hydroloyic balance." The Division has <br />evaluated the potential impacts of the Npex Mine to the fydrologic <br />balance in more detail since the Kaman Tempo study. The additional <br />hydrolggic data analysis confirms the statements of the Kaman Tempo study <br />that there will be negligible off-sites impacts to the hydrologic <br />balance. Even though the potential for impact is minimal, Sunland Mining <br />Corporation has proposed to continue ~rionitoring the spring flow, mine <br />inflows, surface and alluvial water flows for both quality and quantity <br />of water to substantiate the predictions. <br />The assessment of the probable cumulative impacts of all anticipated coal <br />mining in the general area on the hydrologic balance, as described in <br />2.05.6(3), leas been made by the Division, and the operations proposed <br />under the application crave been designed to prevent damage to the <br />hydrologic balance outside the proposed permit area. <br />X. Climatolo ical Information and Air Resources Protection- <br />Rules 2.04.8, 2.05.4 2 h 'L.05.6 1 and 4.17 <br />The appropriate information dealing with climatology and air resources at <br />the site is contained in Section 2.04.8 pages 71-82 of the permit <br />application. The applicant included very detailed weather information <br />from the Pyramid cooperative weather station location 6 miles southwest <br />of the permit area. <br />On March 8, 1981, Mr. and Mrs. Yorty, adjacent landowners, expressed <br />concerns about air resource protection. The comments addressed dust <br />problems that were detrimental to Mr. Yorty's asthmatic condition. <br />
