Permit Revision PR-09,Response to Adequacy Reviews No. 2 and 3
Dear Ms. Reilley:
Enclosed are two copies of our response to your Adequacy Review#2 letter of December 24,2018 and a
third Adequacy Review letter of February 22, 2019 to Trapper's Permit Revision PR-09 application. We
have used your original letter as the base format,with our responses following each of your comments.
Only the remaining outstanding items from the Adequacy Review#2 letter have been included in this
response as most items have been addressed adequately.
A second response to the third adequacy letter is attached to this letter detailing the importance of the
spoil handling in the L-Pit area concerning safety and pit stability. It furthers explains the necessity of a
variance from Approximate Original Contour in order to successfully reclaim Cut#20 of L-Pit. This
document also includes further information pertaining to the BLM Royalty Rate reduction Trapper sought
in conjunction to the highwall instability issues in L-Pit.
Also attached for reference is page 2-4 from the "Radian Corporation, Evaluation of Hydrologic Impacts
of Disposing of the Craig Station Power Plant Wastes in the Trapper Mine, Moffat County Colorado."
This attachment pertains to Trappers last response on item 26.
The following revised permit tables are enclosed: Table 4.8-6 (pages 1 [4-185], 2 [4-186] and 3 [4-186a])
and Table 4.8-7 (pages 1 [4-189], 2 [4-190] and 3 [4-190a]).
The following revised maps are enclosed: M6(sheet 2)and M 13 (sheet 2). Revisions of these two maps
was required to show the Johnson Coal Stockpile as approved in TR-121, not originally shown on the PR-
09 materials when submitted. Inclusion of the pile was necessary to properly depict the mine site and
bonding requirements once PR-09 is approved and the maps provided with TR-121 are superseded.
