INTEROFFICE MEMORANDUM
SAFETY
SUBJECT: Bowie No. 1 Mine, Permit No. C-81-038, Permit Revision No. 4
As requested I have reviewed Permit Revision No. 4 regarding transfer of a large portion of the
Bowie No. 1 permit area to Bowie No. 2. You specifically requested that I look at ground water
information contained in the revision application. There is no plan for continued monitoring of deep
bedrock groundwater because Bowie No. I was granted a significant monitoring reduction plan in
1993 with TR -24 as indicated in the application. Some shallow alluvial and colluvial wells and
selected springs will continue to be monitored. The application states that there were discussions
between BLM, CMLRD, and the operator and a significant reduction in the groundwater hydrology
monitoring program was addressed and approved. As stated on page 122 of the application,
selected springs, deep bedrock groundwater monitoring wells, and shallow alluvial monitoring
wells were removed from the program.
Given this current plan, my main concern after reviewing the application is the presentation of the
information regarding deep bedrock groundwater. Some of the text regarding the deep bedrock
groundwater descriptions and specifically the baseline data collection could be better described and
clarified which may prove to be useful for the transfer of groundwater monitoring and associated
liability to the Bowie No. 2 permit. Keep in mind that the text that I refer to below has already been
approved by our Division so we should probably discuss my cormnents after you have had a chance
to review them before forwarding them on to the operator.
In reference to Table 4B seven wells are identified as being completed in the coal member of the
Mesaverde Fonnation; however, none of them are presently monitored. I have briefly looked
through the older AHRs to determine how these wells have been utilized in the past and there is
some water level data available for some of these wells (DH -60 and DH -65) but I have had
difficulty locating any water quality information. The text describing deep bedrock groundwater
monitoring is somewhat unclear as described below in Comment 2.
