-32- from the interception of a fault deviation from expected inflows. at Mt. Gunnison using the Jacob radius will extend to 0.4 miles reasonable. are possible and would cause a Radius of influence calculations done straight-line method project that the in five (5) years. This value seems It is projected by the applicant that most springs in the lease area derive their water from the Barren Member of the Mesa Verde Group, and further, that pumping from the mine in the F-seam should not affect aquifers in the zone more than l00 feet above the seam. Although the 100-foot estimation is somewhat generalized, this conclusion probably is realistic. Mining Will impact springs issuing from the F-seam and beds in the Barren Member immediately overlying it. Interference with springs will be most likely in areas of shallow overburden. In zones of substantial fracturing, springs issuing from beds more than 100 feet above the F-seam may be affected. If subsidence occurs, all springs overlying excavated areas have some potential for being affected in the five year permit area. However all water from the springs will remain in the ground-water/surface water regime of the North Fork of the Gunnison and there will be no impact to down stream water rights.. The applicant anticipates no degradation of ground water quality during mining. All water developed in the mine is to be used for dust control. The applicant confirms that "any effluent will be treated as necessary to meet water quality standards prior to discharge." The applicant further confirms "there will be no uncontrolled mine water discharge after mining is complete which might otherwise degrade surface streams or ground water" (v.l, -p. 2-349). The mine operation plans indicate (v.l, -p. 3-39) that mine discharges may occur when WECC's water rights are not in priority, but again, that all discharges will be appropriately treated. The operation plan further indicates most water used for dust control will be absorbed on the coal and carried from the mine thereby minimizing the quantity to be treated. Any discharge will be delivered and treated in the sedimentation ponds and discharge as specified in the NPDES permit. In order to assess the quantity, quality, and source of mine inflows, and in order to assess the impacts of the mine workings on the hydrologic balance within the mine plan adjacent areas, the Division is requiring the following stipulation to the permit: Stipulation No. 6 THE APPLICANT SHALL CONTINUE TO SUBMIT TO THE DIVISION, AN ANNUAL REPORT OF INFLOWS, DISCHARGES AND CONSUMPTION OF WATER WITHIN THE MINE. THIS REPORT IS TO INCLUDE A MINE WORKINGS MAP SHOWING THE LOCATION AND QUANTITY OF INFLOWS, A TABLE KEYED TO THE MINE MAP WHICH SHALL CONTAIN THE SOURCE (I.E. FAULT, FRACTURES, ETC), QUANTITY, DURATION, AND QUALITY (I.E. PH, ELECTRO-CONDUCTIVITY AND TEMPERATURE) OF ALL INFLOWS; A TABLE CONTAINING RECORDS OF WATER DISCHARGED FROM THE MINE, CONSUMED IN THE MINE, AND IMPORTED FOR USE WITHIN THE MINE, A DISCUSSION OF THE WATER BALANCE WITHIN THE MINE, AND FINALLY A PROJECTION OF HYDROLOGIC IMPACTS OF MINING IN THE UPCOMING YEAR.
