West Elk Mine • tributary to the Third West seals is about 2 gpm, compazed to the 18 to 30 gpm observed by Bear. The outflow tributary to the Second West bleeder seals would be less than 0.5 gpm. W WE also performed flow path analyses for inflows observed within the Beaz Mine. The water emerging from the Third West seals, the only water reported in 1995, would not flow to the base of the Beaz Mine's C-seam to B Seam slopes, but rather to the extreme northeast corner of the mine. Water in this location could not possibly have entered the Edwards Mine or contributed to the Edwazds Portal flows that emerged neaz the toe of the new landslide activity in November 1997. Only water emerging from the Second West bleeder seals would be tributary to the base of the slopes, where it could enter the Edwards Mine only after traveling through another unmined coal block sepazating the Bear No. 3 B Seam mine from the abandoned Edwazds Mine. Given the orientation of the BEM and 14HG faults, MCC has considered the potential for downgradient migration of groundwater stored in the proposed Box Canyon sealed sump towazd the abandoned B Seam workings of the Sanbom Creek Mine (a B Seam mine on the north side of the North Fork that is no longer active). The very low permeability of the coal seams and surrounding formations suggest that very limited downgradient movement of water from the sealed sump is likely. Projections of the BEM and 14HG fault systems show that, if they were to extend across the North Fork, they would not intersect any of the B Seam workings of the Sanborn Creek Mine (i.e., projections are to the east of the mine workings) and therefore unlikely to be a receiver of water contained in or stored over these fault systems. These fault zones do, however, project into the F Seam workings of the Hawks Nest Mine (east of the Sanborn Creek Mine) which neither encountered these faults zones nor experienced any significant groundwater inflows. MCC believes that the water-bearing BEM and 14HG fault systems are unique to West Eik Mine and, as a result, do not extend any significant distance away from the permit area. As a result, the proposed storage of water within the Box Canyon Sealed Sumps is not expected to increase groundwater inflows within the abandoned downgradient mine workings primarily due to the low permeability of the coal and the lack of hydraulic connection between the mines via the fault systems. Potential Impact of NW and NE Panels Sealed Sumps on F Seam Workings WWE has evaluated the potential for water stored in the NW and NE Panels sealed sumps to impact the abandoned F Seam workings. This analysis showed that the maximum build-up of water, or rise of water level or water elevation, in the sumps would be less than 150 feet. Since the F Seam is approximately 400 feet above the B Seam, there will not be any water transmitted from the sumps to the F Seam workings. 1.05-148 Revised November 1004 PRl0
