RE: Proposed Rep cement for Stipulation 112 for the Trapper Mine
Pursuant to your request.i have reviewed the stipulation amendments requested
by Trapper Coal Company. The company's proposal agrees to the completion of
the annual post-mining topography but delays the completion of the first map
until January, 1989. This does not significantly effect our control of the
situation, particularly since flyash is not now being disposed of within the
backfilled area. With the following minor amendments the stipulation modification
is acceptable, in my opinion.
Stipulation 2A:
THE DIVISION DIRECTS THE PERMITTEE TO MONITOR POST-MINING TOPOGRAPHY OF~
BACKFILLED AND REGRADED SURFACES OF THE DISTURBED AREA AT THE TRAPPER MINE.
MONITORING FOR THIS PURPOSE SHALL CONSIST OF A CONTOUR MAP (CONTOUR INTERVAL
NOT TO EXCEED 5 FEET) PRODUCED FROM AN ANNUAL SURVEY UTILIZING FIELD OR
AEROPXOTGRAMMETRZC TECHNIQUES ACCEPTABLE TO THE DIVISION. THE POST-MINING
TOPOGRAPHIC MAPS SXRLL BE SUBMITTED TO THE DIVISION FOR REVIEW AND APPROVAL
ON AN ANNUAL BASIS, COMMENCING IN JANUARY, 1989.
The second half of the company's proposal concerns the verification of the
projected overburden swell factor at the Trapper Mine. The proposed stipulation
modification defers resolution of this task to next year. Considering the
life of the mining operation this amendment also appears to be acceptable, in
my opinion. With the following minor amendments the stipulation can be
approved.
Stipulation 2B:
TTIE DIVISION DIRECTS THE PERMITTEE, ZN CONSULTATION WITH 2XE DIVISION, TO
PREPARE AND SUBMIT FOR APPROVAL A PLAN FOR VERIFICATION OF THE 25$ OVERBURDEN
SWELL FACTOR PROJECTED BY TXE PERMITTEE FOR THE TRAPPER MINE. THIS PLAN SHALL
Hf:' SUBMITTED IN ACCEPTABLE FORM WITHIN 6 MONT1f5 FOLLOWING PERMIT APPROVAL.
