IV. PROPOSED DECISION
Based on the observations above, the Division proposes to approve Coors Energy Company's
request for a Phase II bond release for the Keenesburg Strip Mine. This proposed decision will
release the applicant from a portion of the liability in accordance with Rule 3.03.1(2)(b). The :Phase
II bond release applies to 51.05 acres consisting of parcels 2, 5, 6, 7, 9, 10, 15, 16, 19, 23, and 29.
The Division in SL -03 redefined the original bond amount of $4,402,022.00 to be the "applicable
bond amount' ' for determining bond release, with no subtraction of structural demolition costs prior
to calculating Phase WFIII liability release values.
In SL -05, Coors Energy Company has requested a bond release of $179,646.00. However, the
Division has estimated the cost to complete remaining reclamation tasks and maintenance following
the proposed approval of SL -05 to be $2,001,475.00 (see Appendix A). Rule 3.03.1(3)(d) requires
that adequate bond be retained to allow the Division to conduct any remaining reclamation tasks in
the event that the Division takes over the permit. Based on the Division's estimate of remaining
liability and the Division's observations of reclamation success, the Division proposes to release
$120,385.00 (costs associated with Phase II revegetation and topsoil replacement tasks) of Phase II
reclamation liability. The remaining bond of $2,001,475.00 shall be sufficient to assure completion
of the remaining reclamation work at the site if the work had to be performed by the Division,
including the cost of reestablishing vegetation on any revegetated areas should those areas fail.
The following table summarizes the history of liability at the Keenesburg Mine.
Reclamation work which remains to be done at the site includes completion of backfill and grading
of the remaining portions of Pit B; ripping and regrading of interior access roads; topsoil
