Outfall Ol 1 was monitored for the full suite of groundwater <br />parameters quarterly for 1996, as required by Technical Revision No. 20. The data for Outfall <br />O1 lis contained in section 5 <br />During 1994, MSHA granted approval to use the idle C-Seam workings as a sump. <br />This has increased the retention time to settle out the suspended solids from the mine <br />dischazge water.

No <br />significant changes to mine inflow have occurred in the past year. <br /> <br />U <br />
