A table of the No. 3 Mine water level measurements and a graph which shows the increase
and decrease in water level over time are presented in Appendix III.
The discharge from the No. 3 Mine and No.
The average flow measurements from the No.
summarized below.
I Mine were combined on August 11, 1995.
3 Mine for the period 1990 through 1994 is

Water from the No.1 Mine and No. 3 Mine continue to be treated by the passive water
treatment system. The quality of the discharge is presented in a table in Appendix IV. A
six inch diameter PVC pipe was installed from the old air shaft to the long pond in 1997 to
handle an increased flow from the old air shaft.
The following table presents arithmetic averages of flow and quality measurements taken
at Outfall 001. Outfall 001 is the discharge point for the passive water treatment system.
As of August 11, 1995, the discharge from Outfall 001 is the combined discharge from the
No. 1 Mine and the No. 3 Mine.
