XXI. Bonding (2.05.4(2)(b)
The reclamation costs section of the original permit application, found
on pages 4-34a through j of Volume 1, has been reviewed by the
Division. All problems concerning the reclamation cost estimates that
were raised in the February 6, 1981 Preliminary Adequacy Review have
been satisfactorily resolved and the proposed operation is in
compliance. The total cost for reclaiming the operation has been
calculated by WECC to be $4,106,639.00.
WECC has submitted reclamation cost estimates for all five phases of
construction in the lower waste pile permit revision. These estimates
have been reviewed by the Division. WECC proposes an incremental bond
for the lower waste pile. [ACC would submit an additional $48,108.00
in reclamation bond. this amount would cover reclamation of the lower
waste pile through phases I and Ii of its construction. Additional
bond would be required before Phase III construction could commence,
With the inclusion of the following stipulation the Division finds the
incremental bonding proposal for the lower waste pile acceptable.
Stipulation No. 17
WECC MUST SUBMIT ADDITIONAL BOND, IN THE AMOUNTS DESCRIBID IN THE LOWER
WASTE PILE PERMIT REVISION APPLICATION, AT LEAST THIRTY (30) DAYS PRIOR
'PO THE CODM'4T OF CONSTRUCTION OF PHASES III, IV, and V OF THE
i.GWER WASTE PILE. THESE ADDITIONAL BONDS MUST BE APPROVED AND AC'CEPTE.D
BY THE DIVISION PRIOR 7D CUNSTRUCPION FOR THESE PHASES.
XXII. Sealing of Drilled Holes and Underground Openings (2.05.4(2)(8), 4.07)
Information demonstrating compliance with the above mentioned rules can
be found in Volume 1, section 3 and 4 of the original permit
application. The operation is in compliance.
XXIII. Subsidence (2.05.6(6), 4.20)
WECC prepared, submitted and subsequently revised a report entitled
"Subsidence Evaluation for Mt. Gunnison No. 1 Mine". This report was
prepared by WECC's Mine Engineering Staff and is included as exhibit
3.4.S.A within the amended permit application.
As a portion of its November, 1984, "Application to Revise the Mining
and Reclamation Plan for the Mt. Gunnison No. 1 Mine", to add 320 acres
to the permit area, WECC submitted a revised subsidence monitoring
plan. WECC stated in the application that the requested 320 acre
permit area expansion "...is, in part, to accommodate a revision to the
underground mining sequence necessitated by geologic conditions
encountered during mining which required that the mains be relocated".
Further, the requested area expansion allowed the relocation of the
required subsidence test panel. WECC observed, and the Division
concurred, "Relocating the five year permit boundary westward will
