The Division has completed a preliminary adequacy review of the technical revision application
(TR -77) submitted by Bowie Resources, LLC (BRL) for the Bowie No. 2 Mine. The revision
proposes the use of overburden materials as a substitute for topsoil in the Gob Pile #2 area.
We have the following comments and questions regarding the application.
1. Revised page 2.04 -101 submitted with TR -77 indicates that select overburden materials
may be used as a replacement and or supplement for the topsoil on the coal mine waste
piles. The language used should be updated to specify "coverfill material" may be used as
a supplement to the topsoil material as this is the only type of overburden material that
was evaluated and considered for this use. The use of other types of overburden material
as a replacement and or a supplement to topsoil would require a separate analysis with
the justification and test results submitted to the Division for approval in accordance with
Rule 4.06.2(4). Please revise Page 2.04 -101 to clarify that "coverfill materiaP' is the only
material that will be used as a topsoil supplement.
2. The first sentence of item (3) on revised Page 2.04 -101, should be updated to clarify that
the coverfill material will only be used to "supplement" the available topsoil material to
be replaced. The coverfill material should only be considered as a replacement to the
topsoil that was not salvageable in accordance with the variance approved in TR -76.
Please revise Item 3 of page 2.04 -101 to clarify that coverfill material will be used to
supplement available topsoil when topsoil is not available for salvage, and not as a
general replacement for topsoil.
3. The first sentence of item (3) on revised Page 2.04 -101 should specify that coverfill
material will be used to supplement the topsoil to be replaced on the gob pile #2/4 area
where the topsoil deficiency exists. The submitted revised page broadly states that
substitute material will be utilized on coal mine waste piles and this material may not be
