Notice of Intent to Seek Phase I, II, & III Bond Release
To Whom It May Concern,
Tri-State Generation and Transmission Association Inc. (Tri-State), is the parent
company to Axial Basin Coal Company, which is the general partner to Colowyo Coal Company
L.P. (Colowyo). Therefore, Tri-State on behalf of Colowyo is notifying you that Colowyo is
submitting an application for Phase I performance bond release on areas reclaimed in from 2012
to 2018, and Phase I, II, and III bond release on a post -mine channel reclaimed in stages from
1992 to 2005. This application for Phase 1, Il, and III bond release, when submitted, will be
denoted as SL -15.
A Phase I bond release includes an evaluation of the backfilling and grading to the
approved post -mining topography.
A Phase I1 bond release application focuses on vegetative cover and species composition
in support of the post mine land use. Further, a Phase II evaluation demonstrates the contribution
of suspended solids to streamflow or runoff is not in excess of pre -mining levels or levels
documented for comparable non -mined areas. Finally, the Phase II application demonstrates that
topsoil depths are in compliance with the approved mining permit.
A Phase III bond release evaluation demonstrates achievement of Phase I and Phase II
bond release, a minimum of five (5) years since the last seeding and rill and gully repair, and the
reclamation parcels have met the requirements of the revegetation success criteria for two years.
This written notice is sent to you pursuant to Colorado Division of Reclamation, Mining
and Safety Rule 3.03.2(1). Prior to filing a request for the bond release, Colowyo must send
written notices in accordance Rule 3.03.2(1), of intention to seek bond release. Additionally, for
your convenience, enclosed please find a copy of the Public Notice, which will be published in
the Craig Daily Press in the near future.
If you should have any questions regarding this notice for the Phase I bond release
application, please contact Tony Tennyson at your convenience at [phone].
