Sulfur is off-gassing and the water <br />appears of good quality. MCC is able to capture all inflow to the mine. They are prepared to <br />bypass as soon as approval is received from the WOCD. <br />MCC has shut down Pond MB-2R (Outfall 004) discharge flow. Yesterday morning, they <br />completed discharge of Pond MB-1 through Outfall 002. <br />With the reduced flows to the ponds and directly discharging through the bypass, MCC <br />believes they will have the surface water quality issues under control. <br />Recorded by: Kathleen Sullivan <br />Date: January 28, 1997 <br />cc- Dwain Watson, District Engineer, Field Support Section <br />David Berry/Mike Boulay, DMG <br />Original to MS-3 File <br />
