RE: North Thompson Creek Mine Mid-term Review
C-81-025
I reviewed information related to topsoil and vegetation in the North Thompson Creek PAP
(Sections 3.8, 3.9, 4.4.2.4, 4.4.3.3, Appendices 3-V and 3-W), the 1994 Annual Reclamation
Report, the Division's 1993 Findings document, and the 1993 Phase II bond release request
for the mine site. Here are some points Minrec should revise or update in the PAP, as well
as some helpful hints for your mid-term review.
For Minrec:
1. Page 3-123 mentions the 56 acre reference area originally approved for comparison
of vegetative success. Since this reference area was superseded by an extended
reference area (TR-14), mention of the 56 acre reference should be deleted.
2. The vegetative baseline data for the loadout in pages 3-128 through 3-132 could be
dropped from the permit, since the loadout is no longer part of the permit area.
Discussion of loadout reclamation in pages 4-85 through 4-94 could also be removed.
(BARB- If this is not consistent with what you're telling him to do with loadout info in
the PAP, forget it.)
3. The discussion of the interim reclamation plans in pages 4-42 through 4-47 could be
removed from the permit since the results of that work have been replaced by the
permanent reclamation.
4. Page 9 of Appendix 3-W contains a reference to the old diversity standard on page
4-64. Page 4-64 now includes the currently approved diversity standard. Page 9 of
the appendix should be revised.
5. Although use of an extended reference area in the mountain shrub community
adjacent to the mine was approved in TR-14, there is no map in the permit showing
the location and extent of the extended area. Please include a map indicating the
