The Division has received a copy of the 2009 Annual Hydrology Report (AHR) for the
North Thompson Creek Mine. The AHR was dated 4 January 2010 and received by the
Division on 6 January 2010. Thank you for your timely submittal of this report.
The 2009 AHR states that "The operator applied for final bond release (and)... It
appeared the final bond release would become final- during the year so no hydrology
monitoring was performed." The reports further state that "the monitoring program no
longer includes the requirements of the Colorado Discharge Permit... since it was
terminated by the Department of Health effective March 14, 2005."
On 22 December 2009 the Division proposed a decision to partially approve the Phase I,
II and III Bond Release, SL-06, for the North Thompson Creek Mine. The surface
portion of the mine that contains the developed water resource (the Mine #1 and Mine #3
discharges and their associated pipeline corridors, the Long Pond, treatment ponds T1
and T2, sediment pond P9 and the pipeline corridor for the discharge from T2 to the
North Thompson Creek) remains in the permit as disturbed acres.
There is no current water monitoring required at the North Thompson Creek Mine and,
therefore, no data to be submitted. Sampling of monitoring wells D-lA and D-2A, the
final two wells in the hydrologic monitoring plan, was discontinued with the approval of
Technical Revision 23, approved on 23 February 2004. Sampling of the mine water
discharge and other NPDES discharges was discontinued with the termination of the
Colorado Discharge Permit effective 14 March 2005.
Although there is no current water monitoring at the North Thompson Creek Mine (based
on the termination of groundwater monitoring with TR-23 and the termination of the
CDPS permit), the Division is not eliminating the requirement for the submittal of the
