Executive Director
The Division of Reclamation, Mining and Safety (DRMS) has reviewed Sage Creek
Coal Company's (SCCC's) adequacy response and permit application update package
dated March 16, 2010 (received by our office March 18, 2010). SCCC submitted the
package in response to DRMS adequacy comment letters of February 11 and 16, and
March 2, 5, and 11, 2010.
We previously found the following DRMS comments to be adequately addressed by
SCCC: 1 through 4, 6 through 9, 13, 15, 16a, 16b, 16c(ii), and 17 through 47. Our
review of the March 16 package has found that SCCC's responses adequately address
the following DRMS comments: 5, 10, 11, 12, 14, 16c (i and iii), 48 through 54, 56, 58
through 65, and 67.
Set forth below are the remaining DRMS comments that have not yet been adequately
addressed. DRMS is in the process of preparing a reclamation cost estimate which may
result in additional adequacy comments that we will send to you when they become
available.
55. Please revise the subsidence monitoring plan in the permit application to include:
a. Premining surveys of Boeddeker Reservoir #15 and County Road 27,
b. A premining survey of the thalweg of Grassy Creek, and provision for a
postmining survey of the creek in the event mining is not subsequently
proposed beyond the current plan,
c. Semi-annual reporting of subsidence monitoring results, as required by
Rule 2.05.6(6)(c)(i)(E), and
