F. Impoundments <br />The applicant has not proposed the use of alternative design criteria and <br />specifications for impoundment design and construction (4.05.9). <br />G. Surface and Groundwater Monitoring <br />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, irrigation ditches, ephemeral drainages, <br />and several springs, both upstream and downstream from the azeas <br />affected by mining. Ground water levels and quality are monitored in the <br />D-2 coal seam, the B-2 coal seam and the North Fork alluvium. <br />Monitoring and reporting of mine inflows was added to the hydrology <br />monitoring plan with the approval of Permit Revision No. 2. <br />H. Transfer of Wells <br />The Division does not propose to approve the transfer of any exploration <br />or monitoring well (4.05.15(13)). <br />Dischazge of Water into an Underground Mine <br />The Division is not proposing to approve the diversion of water from a <br />surface or underground mine into underground mine workings. <br />Stream Buffer Zones <br />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 summarized 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 />24 <br />
