E. Acid-forming and Toxic-forming Spoil <br /> Based upon information provided by BRL, the Division does not anticipate that any <br /> acid-forming or toxic-forming spoil will be encountered during the operation of the Bowie <br /> No. 2 Mine (4.05.8(3)). <br /> F. Impoundments <br /> The applicant has not proposed the use of alternative design criteria and specifications for <br /> impoundment design and construction(4.05.9) other than the design for Pond D, <br /> discussed above. <br /> G. Surface and Groundwater Monitoring <br /> The applicant will conduct monitoring of surface and ground waters in a manner <br /> approved by the Division. The surface and ground water monitoring plan is specified in <br /> Section 2.05.6(3)(b)(iv)of the Bowie No. 2 Mine PAP(4.05.13(1)). BRL monitors <br /> surface water quantity and quality in perennial streams, irrigation ditches,ephemeral <br /> drainages, and several springs,both upstream and downstream from the areas affected by <br /> mining. Groundwater levels and quality are monitored in the D-2 coal seam,the B-2 coal <br /> seam and the North Fork alluvium. Monitoring and reporting of mine inflows was added <br /> to the hydrology 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 or monitoring <br /> well(4.05.15(13)). <br /> 1. Discharge of Water into an Underground Mine <br /> The Division is not proposing to approve the diversion of water from a surface or <br /> underground mine into underground mine workings. <br /> J. Stream Buffer Zones <br /> The Division does not propose to approve surface or underground mining activities within <br /> 100 feet or through a perennial stream or stream with a biological community(4.05.18(1)). <br /> K. Probable Hydrologic Consequences <br /> BRL provided an analysis of the Probable Hydrologic Consequences to be expected as a <br /> result of mining and reclamation operations at the Bowie No. 2 Mine. The analysis is <br /> presented in Section 2.05.6(3)(b)(111)of the PAP.Possible hydrologic impacts to the local <br /> surface and ground water systems are summarized below. <br /> Surface water systems directly above the mine working, and within the permit area,could <br /> be minimally impacted due to mine subsidence. Surface cracking resulting from <br /> subsidence could occur within the ephemeral and intermittent stream channels which <br /> overlie the mine; however, such impacts should be minimal and surface cracks should fill <br /> 19 <br />
