RE: North Thompson Creek Mine (C-1981-025)
2007 and 2008 Annual Hydrology Report (AHR)
Dear Mr. Stover:
The Division has received copies of the 2007 and 2008 Annual Hydrology Reports for
the North Thompson Creek Mine. Thank you for your timely submittal of these reports.
Both reports state 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."
In addition to applying for final bond release, 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-IA 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 termination of the Colorado Discharge Permit on 14
March 2005.
Although there is no current water monitoring at the North Thompson Creek Mine, the
Division is not eliminating the requirement for the submittal of the Annual Hydrology
Report. This is due to the fact that on or around 27 March 2008 Minrec was notified by
the Colorado Department of Public Health and Environment, Water Quality Control
Division (WQCD) that the North Thompson Creek Mine would need to reapply for a
discharge permit for the site. On 28 April 2008 Minrec reapplied for an NPDES permit
and that permit is apparently still under review by WQCD. Once WQCD approves and
issues a new NPDES permit for the North Thompson Creek Mine water monitoring will
need to be reinitiated and Minrec will need to submit that data in the following year(s)
AHR.
