The fault will be encountered by the mine at a future time and will <br />probably produce water again. Additionally, it is anticipated that mine <br />inflows will increase as the workings extend further downdip into the <br />predicted saturated portion of the Cameo seam. In order to monitor the <br />effect of the operation on ground water resources and to assist in the <br />prediction of hydrologic impacts of future permit terms, the following <br />stipulation is required: <br />3. THE APPLICANT MUST SUBMIT TO THE DIVISION AN ANNUAL REPORT <br />CHARACTERIZING THE INFLOWS, DISCHARGES AND THE CONSUMPTION OF WATER <br />WITHIN THE MINE. THIS REPORT IS TO INCLUDE A MINE WORKING MAP <br />SHOWING THE LOCATION AND QUANTITY OF INFLOWS; A TABLE KEYED TO THE <br />MINE MAP WHICH SHALL CONTAIN THE SOURCE (i.e. FAULT, FRACTURES, <br />ETC.), QUANTITY, DURATION, AND QUALITY (i.e. pH, <br />ELECTRO-CONDUCTIVITY AND TEMPERATURE) OF ALL NON-SEEP INFLOWS; A <br />TABLE CONTAINING RECORDS OF WATER DISCHARGED FROM THE MINE, <br />CONSUMED IN THE MINE AND IMPORTED FOR USE WITHIN THE MINE; A <br />DISCUSSION OF THE WATER BALANCE WITHIN THE MINE; AND, A PROJECTION <br />OF HYDROLOGIC IMPACTS OF MINING IN THE UPCOMING YEAR. <br />Examples of the type of inflow report requested are on file at the <br />Division office (see inflow reports for the U.S. Steel Somerset Mine and <br />Western Slope Carbon's Hawk's Nest Mine). <br />An alluvial ground water aquifier has been identified along East Salt <br />Creek. Monitoring wells established in the alluvium indicate that <br />alluvial water levels fluctuate seasonally in response to flow in East <br />Salt Creek. Data collected by the applicant from the Salt Creek alluvial <br />aquifer thus far indicate acarbonate-sulfate type water, similar to the <br />characteristics of the surface water in the system as would be expected. <br />No significant adverse affects on ground water are anticipated for this <br />operation. <br />Salt Creek Mining Company intends to monitor this aquifer upstream and <br />downstream of the mine to identify any affects from mining. The Division <br />therefore requires the following stipulation to verify its conclusions: <br />4. A) THE APPLICANT WILL CONTINUE MONITORING WELLS GW-1 AND GW-4 IN <br />SALT CREEK ALLUVIUM QUARTERLY. AT THESE TIMES THE WATER LEVEL IN <br />THE WELLS WILL BE MEASURED AND SAMPLES WILL BE TAKEN FOR ANALYSIS <br />OF pH, TEMPERATURE AND SPECIFIC CONDUCTANCE. THE RESULTS OF THIS <br />MONITORING WILL BE SUBMITTED TO THE DIVISION IMMEDIATELY AFTER DATA <br />COLLECTION AND ANALYSIS. <br />B. THE REQUIREMENTS OF THIS STIPULATION ARE SUSPENDED BY THE <br />DIVISION ONLY FOR SUCH PERIOD OF TIME THAT THE OPERATION IS UNDER A <br />DIVISION APPROVED TEMPORARY CESSATION OF OPERATIONS AND NO <br />ADDITIONAL DISTURBANCES ARE CREATED. <br />With satisfactory resolution of the stipulations, the operation will be <br />in compliance with ground water hydrology requirements. <br />_lp_ <br />
