G. Surface and Groundwater Monitoring <br />1. The applicant will conduct monitoring of surface and ground waters in a <br />manner approved by the Division. The surface and ground water <br />monitoring plan is specified in Section 2.05.6(3)(b)(iv) of the Bowie No. 2 <br />Mine permit application (4.05.13(1)). BRL monitors surface water quantity <br />and quality in perennial streams, imgation ditches, ephemeral drainages, <br />and several springs, both upstream and downstream from the areas <br />affected by mining. Ground water levels and quality are monitored in the <br />D-2 coal seam and the North Fork alluvium. Monitoring and reporting of <br />mine inflows was added to the hydrology monitoring plan with the <br />approval of Pernut Revision No. 2. <br />H. Transfer of Wells <br />1. The Division does not propose to approve the transfer of any exploration <br />or monitoring well (4.05.15(13)). <br />I. Dischazge of Water into an Underground Mine <br />1. The Division is not proposing to approve the diversion of water from a <br />surface or underground mine into underground mine workings. <br />J. Stream Buffer Zones <br />1. The Division does not propose to approve surface or underground mining <br />activities within 100 feet or through a perennial stream or stream with a <br />biological community (4.05.18(1)). <br />K. Probable Hydrologic Consequences <br />BRL provided an analysis of the Probable Hydrologic Consequences to be <br />expected as a result of mining and reclamation operations at the Bowie No. 2 <br />Mine. The analysis is 'presented in Section 2.05.6(3)(b)(iii) of the permit <br />application document. Possible hydrologic impacts to the local surface and <br />ground water systems aze summazized below. <br />Surface water systems directly above the mine working, and within the permit <br />azea, could be minimally impacted due to mine subsidence. Surface cracking <br />resulting from subsidence could occur within the ephemeral and intermittent <br />stream channels which overlie the mine; however, such impacts should be <br />minimal and surface cracks should fill with sediment relatively quickly. Actual <br />interruption of surface flows should not be significant. <br />Stock ponds located above the mine, and within the permit azea, could also be <br />impacted by subsidence; however, significant impacts aze unlikely, due to the <br />29 <br />
