It is monitored downgradient from Eagle's underground workings in well TR-7A. Data from this well indicates wmpliance with the Basic Standards if a Basic Standards Q CWQCC compliance point were established at the well for Ground regulations y~ location. NPDES monitoring of mine pumping at Water 41 4 and 41.5 outfalls 024 and 003 shows Bumped water would . not degade Bound water if the lumped water seeps through the walls of the workings. The Bumped water is regularly pumped down to prevent flooding of the workings. The pumping limits the head acting on the walls of the workings, thus limiting s a e. R.
