RE: Coal Basin Environmental Audit
Dear Mr. Harlan:
The Division of Minerals and Geology wishes to provide an
additional comment regarding the environmental audit which you will
be undertaking at Coal Basin.
As we briefly discussed at our site tour on May 13, 1996, there is
a possibility that Dutch Creek may eventually be routed through the
facilities area and flow into Coal Creek in the vicinity of the
present mine gate. Excavation of a portion of the facilities area,
probably including the general location of the old Morrison Knudsen
shop, will occur if the diversion of Dutch Creek is accomplished.
The Division believes that it would be to the benefit of the
bankrupt estate, potential buyers of the property and to the State
to more fully understand the subsurface conditions in the vicinity
of the proposed stream channel relocation project. The spring and
seeps along Coal Creek should provide an indicator of the general
subsurface conditions of the area. However, information specific
to the area of proposed excavation would be most useful in helping
to determine the feasibility of proceeding with the diversion
proposal. To this end, we believe that at least two monitoring
wells within the facilities area should be completed to below the
ground water surface at base flow. One well should be situated
north of the Morrison Knudsen shop, with a second well completed
one hundred to one hundred and fifty feet to the south of the shop.
A third well could be established to the east of the shop to act as
a control point.
These wells should be sampled for VOC's, PCBs, metals and
inorganics.
Thank you for your consideration of this matter. We look forward
