RE: 1993 and 1994 Annual Hydrology Reports, Somerset Mine, $`C-81-
022, Somerset Response Review
I have reviewed the information submitted by the Somerset Mine with
regard to the Division review of the 1993 and 1994 Annual Hydrology
Report and have the following comments:
The operators response was somewhat lengthy (14 pages) and somewhat
defensive with regard to the Division's questions. Part of this
could be that my memo to you and your cover letter were fairly
brief and included the threat of a potential enforcement action.
Given this fact, I will provide some additional information as well
address the operators responses to our initial questions. I have
included my original question as appropriate.
Original Division question:
General Comments
The operator should include a discussion of the results of
monitoring and how it supports or contradicts the probable
hydrologic consequences section of the permit. Currently, the
operator is only re-iterating the data collected for the year.
Clarification of Division Concern:
The Division is requesting, as of now, and as Rule
4.05.13(4)(c)(iii) allows, that the operator include a
discussion and analysis of the data collected and relate it to
the Probable Hydrologic Consequences that are specifically
discussed in the permit. We appreciate and welcome a brief re-
iteration of the results of monitoring, which was done very
well by the operator in the 1993 and 1994 AHR's. However, of
particular interest is whether the data supports, refutes or
otherwise alters in any way the probable impacts of mining. It
is this type of discussion that the Division desires be
included in the AHR.
