Michael B. long
Division Director
Please find enclosed the Proposed Decision Document for the Phase II Bond Release request for
the North Thompson Creek Mines. The Division proposes to deny the Phase II Bond Release at
the mine site, primarily because of the likelihood that the diversity standards will not be met
without additional revegetation. The additional seeding required to meet the diversity standard
will possibly necessitate significant re-disturbance. Therefore, you are advised not to reclaim
the existing sediment ponds at the mine site prior to establishment of a more diverse stand of
vegetation.
As an additional note, the permit currently requires backfilling and grading of the No. 1 Mine
Portal Area. If it is your intention to reclaim this area in another manner, you must submit a
technical revision to that effect. Please be advised, however, that the Division is not inclined to
approve leaving the portal area as it stands. Therefore, the TR should provide for securing the
portal area and protecting it permanently from public access. The TR should also include
backfilling and grading.
Finally, reclamation of the road leading to the portal is not addressed in the permit application
package. Although the road is reported to have been installed pre-law, it was in use during the
permit term and, as such, should be reclaimed in accordance with the requirements of
Rule 4.03.2(7), unless the conditions of Rule 4.03.2(11(f) apply. A minor revision which
addresses the post-mining fate of the fan portal access road should be submitted.
If you have any questions, please call me at [phone] x 353.
Sincerely,
