analyses secured annually. Since the Trout Creek may be the <br />• source, at least in part, of the water inflow into the No. 5 Mine, <br />additional data, systematically collected, on the water levels in <br />these wells would be useful in evaluating the impact of the mine <br />inflow on the Trout Creek aquifer. Any test data from these wells <br />would be 'ielpful in the determination of hydraulic conductivity and <br />storativity of the Trout Creek. Empire Energy should add monthly <br />determinations of water levels for the No. 5 and Okie Plaza wells <br />to its future monitoring plan and supply what it now has or may <br />secure i n the future i n the way of test data for the Trout Creek <br />wells. <br />RESPONSE: Page 2.04.7-6 and Exhibit 29, Water Quality Monitoring <br />Manual - Empire Energy has been revised; Figure Ila, No. 5 Mine <br />Replacement Well Drawdown has been added to address this issue. <br />• 7. Rule 2.07.6(2)(c) Permit Approval or Denial - CHIS <br />The Division is obligated, as part of the application process, to <br />assess the probably cumulative impacts on the hydrologic balance of <br />all anticipated coal mining in the general area. There is some <br />doubt in the Division as to the geologic relationships of the <br />operations at Empire and the adjacent Trapper Mine. An accurate <br />evaluation of the cumulative impacts of these mines requires their <br />relationships be better understood. The Division, therefore, <br />requests the cooperation of Empire Energy and the use of the <br />specific stratigraphic information and geophysical logs Empire <br />possesses from their exploration and evaluation activities in <br />establishing both correlations between the operations at Empire and <br />Trapper Mines and a comprehensive geological framework for the <br />general are. Division personnel may request review of Empires <br />oeoohvsical loos either at Empires offices or other locations to be <br />agreed upon. <br />• <br />39-18 <br />
