H. Transfer of Wells <br />At the conclusion of mining, the two wells used in the operation will be transferred <br />back to the owners at the written request of the surface owners (4.05.14). <br />Discharge of Water into an Underground Mine <br />There will be no diversion of water from a surface or underground mine into <br />underground mine workings (4.05.15). <br />Stream Buffer Zones <br />The Division has approved surface operations within 100 feet of Hay Gulch <br />(entrance roads) and within ephemeral streams (tributaries to Hay Gulch) that have <br />drainage areas greater than one square mile. The Division has determined that water <br />quality standards will not be violated and environmental resources shall not be <br />adversely affected due to these operations. <br />K. Probable Hydrologic Consequences <br />Ground Water Effects <br />The ground water -bearing units having the greatest potential to be affected by <br />mining at the King I and II Mines are the Hay Gulch alluvium, the Cliff House <br />Sandstone, and the Menefee Formation. (GCC has stated that the Point Lookout <br />Sandstone is well beyond the area of influence of the mines because it is <br />approximately 250 feet stratigraphically below the workings. Monitoring data show <br />no impacts from mining at the King I and II Mines.). <br />Hay Gulch Alluvium - The Hay Gulch alluvium has been monitored in the Wiltse <br />well, downstream from the west sediment pond at the King I Mine. GCC also <br />monitors alluvial water quality in a well down -gradient of King II. Monitoring data <br />indicate no significant mining impacts to this unit. <br />Cliff House Sandstone - It appears unlikely that the King I and II Mines will fill with <br />water after mining is finished. With the exception of one inflow event, the mine <br />workings of the King I Mine have been dry. Both mines appear to underlie the <br />updip, unsaturated portion of the Cliff House Sandstone. Impermeable shale and <br />siltstone of the Menefee Formation underlie the workings, and also are unlikely <br />
