(a)(iv) The proposed floor elevation of the mine entries at the portal is 6878 feet.
Map 10, Upper Perched Water Zone - Mesa Verde Formation, shows the
elevation of the ground water in the vicinity of the portal to be above the
proposed portal elevation. Therefore, gravity discharge of water from the
portals is possible. See section 2.05.4(2)(g) for portal sealing options.
The quality of water that may discharge by gravity from the mine would be a
combination of the quality of water being encountered in the B -Seam during
mid 2008, the water quality in the B -1 Sump and the D -Seam. A one time
measurement of the mine inflow taken on June 2, 2008 from the B -8 panel
headgate had the following quality:
