TR -26 has been submitted to the Division to further address ground <br />water monitoring, springs 8s seeps and additional surface monitoring of <br />the Hay Gulch Ditch. Data obtained will be used to update the Probable <br />Hydrologic Consequences and the Cumulative Hydrologic Impact <br />Assessment of Hay Gulch and surrounding areas. <br />No significant hydrologic consequences of mining are anticipated. All <br />coal to be removed from the mine lies above the potentiometric surface of <br />Hay Gulch, the only known aquifer in the area. Therefore, there should <br />be no diminution of water quality or quantity to Hay Gulch from the <br />mine workings or any subsidence related to mining. <br />As there are no surface drainages from the project area connecting to <br />Hay Gulch there is little likelihood of surface water impacts to water <br />quality or quantity from the operation. <br />No water is known to occur in any rock unit above or immediately below <br />the coal seams being mined based on the mining at the National King <br />Mine within or immediately adjacent to the permit boundaries. Again, <br />there is little likelihood of significant impact to quantity or quality of <br />groundwater resources resulting from the King II Mine. Should <br />subsidence related features appear above the mine, water would recharge <br />into the localized groundwater system and not continue off-site, given the <br />dissected nature of the project site topography. <br />The design of the portal facilities and the dip of the strata facilitate <br />drainage of any encountered water in the workings toward the surface. <br />While not anticipated, should water be encountered in amounts that <br />reach the surface, monitoring and control measures will be employed. <br />GCC Energy, LLC <br />Section 2.05.6 <br />Page 5 <br />King II Mine <br />October 13, 2016 (TR -26 AR#2) <br />
