RE: 2001 Annual Hydrology Report Review,l~'ew Elk Mine, #C-81-012
Dear Mr. Koblitz:
The Division of Minerals and Geology has completed review of the 2001 Annual Hydrology Report for the
New Elk Mine, #C-81-012. Please respond to any issues as necessary within 60 days of receipt of this
letter.
General Comments
1. The text of the report continues to refer to [he Golden Eagle mine, apparently from previous
reporting submitted when the same company owned the two sites. Please eliminate references
(e.g. pages 14, 16) to the Golden Eagle mine unless the comments are specific to a comparison of
data or analysis of impact related to the New Elk site.
2. Please identify the superscript " 2" on Table 1.2-1 for the short list.
Monitoring Frequency
Site visits and samples were appazently not taken in accordance with the approved plan. During the first
nine months of 2002, the mine was on a reduced frequency for the hydrologic monitoring plan due to
temporary cessation status. The plan as approved (p. 2.05-90b) allows for a reduced frequency of
monitoring during temporary cessation. The plan indicates when the preparation plant becomes active, the
Division will receive written notification and the frequency of monitoring will be increased. The Division
received written notification that the mine was once again in an "active" slams on October 18, 2001.
Therefore, monitoring should have followed the reduced schedule for [he first nine months of the year and
the increased frequency of monitoring schedule for the last three months of the yeaz. Based on this plan,
deviations from the approved plan are noted as follows.
• No field readings (pH, conductivity, temperature) were reported for the four alluvial wells
PAW-I, PAW-2, PAW-8, and PAW-9 in May (the first semi-annual visit).
• No monitoring data was reported (water level and field measurement) for NEW-2, NEW-3,
NEW-4 for October and November. The field measurements for December for NEW-3 were
also not reported.
