RE: SIB181 Annual Report to WQCC Division Director
The following operations, for which I have been assigned lead specialist responsibilities, are subject to
ground water protection requirements under Rule 3.1.7. A brief compliance status.description is included.
Also, I have attached copies of the appropriate ground water monitoring tracking forms showing the
sampling being done at each site.
Henderson Mine and Mill, Permit No. M-77-342, Clear Creek and Grand Counties
The Division received TR-4 in September 1993 that established a preliminary ground water monitoring and
characterization plan for the Henderson Mine and Mill. TR-5 was submitted in October 1995 and included
the Operator's proposal for a final ground water monitoring and protection plan for the mine and mill. The
Division and the Operator have, at this point, not agreed on a final plan for either points of compliance or
numeric protection levels. The interim plan that has been established includes quarterly monitoring of one
well at the mine, and two wells at the mill. A third well is to be established at the mill during 1998 to gather
ambient ground water quality infor ion ahead of tailings pond expansion.

The Division received TR-3 in September 1993 that established a preliminary ground water monitoring and
characterization plan for the Climax Mine. TR-8 was submitted in October 1995 and included the
Operator's proposal for a final ground water monitoring and protection plan. The Division and the Operator
have, at this point, not agreed on a final plan for either points of compliance or numeric protection levels.
The interim plan that has been established includes quarterly monitoring of two wells in the Ten Mile Creek
drainage basin, one well in the Arkansas River basin, and one well in the Eagle River basin.

Unit was approved as TR-5 on March 6, 1997. The final plan specifies quarterly monitoring of six wells and
