Ill. COMMENTS -COMPLIANCE
Below are comments on the inspection. The comments include discussion of observations made
during the inspection. Comments also describe any enforcement actions taken during the inspection
and the facts or evidence supporting the enforcement action.
This was a partial inspection related to the termination of jurisdiction for the Twin Pines mine,
permit# C-83-058. The Division of Reclamation, Mining, and Safety(Division) is in the
process of tenninating jurisdiction of this revoked site. As per Division policy and in
accordance with Rule 3.03.3, the Division may terminate jurisdiction upon a written
determination that all requirements of the Rules and the Act have been successfully
completed and a final decision has been made in accordance with the bond release
procedures of Rule 3.03. Ground conditions on this day were very dry and the weather was
clear, cold, and windy.
During development of the written findings for the termination of jurisdiction process, it was
discovered that a water monitoring well may still be present and require abandonment and
reclamation. This well TPW-1 was located last month located in a remote area south of the
Coal Sales yard. The purpose of this inspection was to accurately measure the water level in
the well.
Hydrologic Balance
Due to a malfunction (likely low battery) in the water level meter last month, the water level
was crudely estimated at between 105-110 feet below the top of the casing. The last known
measurement of well TPW-1 was in June 1995 and indicated a water level at 144.7 feet
below the measuring point.
Using a 300 foot Solinst
water level meter, the
water level was
accurately measured in
well TPW-1 as 136 feet
2 inches below the top
of the well casing. This
value correlates much
better with the June
1995 measurement prior
to the permit
revocation/bond
forfeiture Board Order.
A check of records filed
with the Division of
Water Resources
indicates no well permit
was filed or approved for
water monitoring well
TPW-1 or any other well in this location.
