Here are my comments on your draft letter to Jim Stover. These are just ideas, so let's discuss your
thoughts about my comments when you finish reading this.
Topic 1: Your comments look fine. However, we need to additionally inform MINREC that as
the Mine No.l portal was rebonded for backfilling and grading following installation
of [he mine water treatment system, MINREC may, a[ some point in the future, also
have to submit a Partial Phase I bond release, as well as Partial Phase II and Partial
Phase ID bond releases, for the Mine No. 1 portal area.
Topic 2: Let's ask MINREC to correct the discrepancy in their permit regarding retention of the
conveyor light use road with a Minor Revision rather than a Technical Revision. If
DMG had not already approved the road for retention, then I would agree with you
that a TR would be somewhat more appropriate. However, as we've already approved
the retention of the road, and all we're asking MINREC do is correct a permit
discrepancy between conflicting sections of the mine permit, an MR would be the
better choice.
While I agree that it makes sense to combine this item with a TR that addresses pond
retention or removal, it could be that we won't see that TR for quite some time. I
would rather have MINREC submit an MR now to (1) correct the permit discrepancy
regarding the conveyor road, (2) add the Old Fan Shaft Area and [he Lower Conveyor
Terrace to permit page 4-64, and (3) demazcate [he limits of the water treatment
system area on a map that would replace Map D-14-16. This revised Map D-14-16
could also contain information about post-mining topography and features approved to
remain or be reclaimed. That way, MINREC could proceed with its bond release
application if it wanted to without first having to decide what to do about the sediment
ponds.
