RE: 1995 Annual Hydrology Report Review
Foidel Creek Mihe
/}C-82-056
Dear Mr. Koehler:
The Division has completed review of the 1995 Annual Hydrology
Report (AHR) for the Foidel Creek mine. Please respond to each
item as appropriate.
General Comments
1. The October date in Table 1 for well 009-79-4 is represented
as 10/26/95. Should this date read 10/26/94?
2. No elevation information is shown on Figure 2 for well FBR-
11B.
3. Figure 85 y-axis is labeled incorrectly as (cfs).
4. Figure No. 28 y-axis is labeled Field Conductivity but TDS is
plotted on the graph and labeled on the heading. Please
Clarify and/or correct.
5. Historic flow and/or level information should be included in
the summary tables for each site in future AHR's, similar to
the historical summary for the water quality parameters. The
Division approved of TCC submitting only current year data, if
it was included with summary tables representing the historic
data for each site. This was done to reduce AHR size and
eliminate repetition. However, to justify this type of
reporting, we need complete summary information .for all
parameters, including flow and water level. -
