Re: Bowie No. 2 Mine (Permit No. C- 1996 -083)
4t" Quarter 2013 Coal Mine Waste Bank Inspection and Instrumentation Monitoring
Dear Mr. Bear:
The Division has received and reviewed BRL's report of the 4th Quarter 2013 Coal Mine Waste Bank
Inspection and Instrumentation Monitoring for the Bowie No. 2 Mine. The report included all of the
information required by Rules 4.10.1 and 4.09.1(11), and noted no appearance of instability, structural
weakness, or other hazardous conditions. Observations on the gob piles are consistent with Division
observations during the quarter.
The report confirms removal of the tree that was observed in the East Diversion Ditch of Gob Pile #2
during the 3rd quarter inspection of the gob pile.
The report includes documentation of the construction of the Gob Pile #3 underdrain, including color
photographs, as required by Rule 4.09.1(11)(c).
The report indicates that all of the compaction tests passed, and that there are currently no outstanding
density test failures. This is consistent with the Division's record of compaction tests.
In the Vibrating Wire Piezometers (VWP) section of the Summary of Instrumentation Monitoring, the
first paragraph describes the series of VWPs that have been installed at CWDA No. 2. Please revise this
paragraph to include the date (month and year) for those that were damaged and fell out of service.
Also, please add a sentence which indicates that the locations of the VWPs are shown on the
Instrumentation Site Plan.
The first paragraph of the VWP section refers to BGI (2009) for completion details of VWP -06 through
VWP -08. Please include this document (it was the 2nd Quarter report for 2009) in the list of References.
The Division has been unable to locate specific information regarding the installation of VWP -09 and
VWP -10. Details for VWP -01 thru VWP -05 were provided in Tables 1 and 2 of BGI (2006), and BGI (2nd
Qtr 2009) provides information on VWP -06 thru VWP -08. Please provide comparable details for the
completion of VWP -09 and VWP -10 (Northing, Easting, Borehole Elevation, and Piezometer Elevation).
The second paragraph of the VWP section discusses pore pressure measurements taken during the
subject quarter. The fourth sentence states, "Readings at these piezometers have generally decreased
since they were installed." This general statement is not supported by the graph presented in the
