RE: Bowie No. 2 Mine
New Application
Reclamation Cost Estimate
I have completed a review of portions of the permit application for rite Bowie No. 2 Mine. I
reviewed the operation and reclamation plans and evaluated the operator's reclamation cost
estimate. In addition to reviewing that information, I generated my own estimate of the
reclamation costs associated with the site. As a result of the review and completing a Division
estimate, I have the following questions and comments which can be piLSSed on to the operator.
The permit application states that drill hole logs are presented in Exhibit 4. That
information could not be located in Exhibit 4 or anywhere else in the permit. In order
for the Division to verify the estimated costs to seal monitoring wells and drill holes, we
need the total depth of each hole to be reclaimed. Please either provide drill logs or a
figure for the depth of each hole.
2. The application that Bowie Resources Ltd. completed for an emissions permit lists the
volume of the coal stockpile as 60,000 tons, and the silo at ei,100 tons. The permit
application, on Pages 2.05-11 through 15 gives volumes of 100,000 tons and 5,000 tons,
respectively. What will be the maximum volume of the stockpile and the silo?
3. Page 2.05-11 includes a description of a control room and weigh bin which will be located
beneath the proposed silo. There are no costs for reclamation of these structures in the
reclamation cost estimate. Please provide a detailed reclamatil~n plan and an estimate
of the cost to reclaim those structures.
4. Page 2.05-12 states that the silo is 170.5 feet tall and 58 feet in diameter. Page 3.02-16
gives dimensions of 110 feet tall and 70 feet in diameter. Which dimensions are correct?
5. Page 2.05-12 of the permit application notes that, depending on contract cost estimates,
the stoker bin will be of concrete or steel construction. Page 3.02-16 Provides an
estimate for cost of demolition based on steel construction. If the construction material
has not yet been decided, the estimate should be based on the more expensive of the two
(worst case), which would be concrete. If there has been a final decision to use a steel
bin, page 2.05-12 should be revised accordingly.
6. Will there be a floor or footing beneath the stoker bin? If so, a reclamation plan and
associated costs need to be included in the permit application package.
7. Page 2.05-13 notes that a fabricated steel water tank will be constructed on an oiled sand
base. The reclamation cost estimate does not include removal of the base. Please
