Executive Director
Ronald W. Cottony
Acting Division Director
The Division has completed review of the 2001 Annual Hydrology Report (AHR) for the Golden
Eagle Mine. Review of our file indicates the Division has not received a response to our review
of the 2000 Annual Hydrology Report (letter dated March 16, 2001 to R. Thompson). Please
review that letter and our comments below, and provide responses as necessary.
2001 Report -Monitoring Frequency
Deviations from the required monitoring plan were noted as follows:
• The annual water sample required for the constituents listed on page 2.05-47d of the
approved permit was not taken for alluvial wells CCAW-1, PAW-5, PAW-6.
• Dissolved iron was omitted from the semi-annual sampling of CCAW-1, PAW-5,
PAW-6 for both semi-annual samples.
• Water level measurements were not taken for GEM-2 for January, March, and April.
• Semi annual sampling for the short list as presented on page 2.05-47d of the
approved permit was not conducted for GEM-2.
• The annual water sample required for the constituents listed on page 2.05-47d of the
approved permit was not completed for GEM-2.
• One of two required semi-annual field measurements was not taken for GEM-2.
Based on severity of the deviations from the approved hydrologic monitoring program, a notice
of violation will be taken by the Division (see CV-2002-008, Golden Eagle Mine, #C-81-013)
2001 Report - Surtace Water Quantity and Quality
Two stations on the Purgatoire River were monitored for flow and field parameters on a quarterly
basis until mid-2001, when the hydrologic monitoring plan was modified by Technical Revision
#52 (TR-52). PRS-2 is located upstream of all Golden Eagle mining activities and PRS-3 is
located downstream of all mining activities. The limited monitoring in the first half of 2001
continues to indicate that no impact to the surface water system is apparent. Total dissolved
