RE: Inspection and Review, Climax Amendment, File No. M-77-493
This report is in response to your memo of August 22, 1989, regarding the
Climax inspection and amendment application.
The inspection left me with the impression that, at present, Climax is doing
the best job possible of reclamation given the climatic conditions and
available resources. The amendment contains a reclamation plan that is as
good or better than the original plan, in most respects. After reviewing the
original permit, the amendment, and accompanying you on the inspection; I have
the following comments and questions.
1 . The reclamation final slopes of the amendment are consistent with the
original permit, except that dam #2 slopes are amended from 2:1 to 3:1
slopes. A definite improvement.
2. The reclamation seed mix (Climax Mix) has changed since the original
permit. Four additional grasses have been added, with resulting changes
in composition by weight. I agree with Gregg Squire that it would be
good to see western yarrow added to the mix. I also think it would be
good to add other forbes to the mix. The Subal pine/Al Dine area seed mix
recommended in the Colorado Inactive Mine Reclamation Program, General
Bid Specifications has a few more forbes and would be a good
recommendation. This mix appears to be a slight modification of the
Climax mix.
3. Commercial granular fertilizer formulations and rates of application
remain the same as the original permit and are adequate.
4. Seeding and mulching methods remain the same and are adequate.
5. The Amendment states that " as a general rule trees and shrubs will not
be planted at the mine except in specific selected areas not yet
identified." The original permit states that "Climax anticipates a long
and beneficial native tree planting program. . . . " The original permit
states that shrub planting rates will be 50-100 per acre." The amendment
states that "shrub plantings presently are envisioned to the extent of
