I haveY~revlewed Perma's March 14, 1985 response to my memorandum of January
14, 1985•regarding revegetation success criteria. Perma has several concerns
regarding the proposed species diversity criterion. As I.understand it, all
other criteria are acceptable to Perma as outlined in my January 14 memo", and
are now a binding part of the permit.
With regard to species diversity, Perma makes several assertions regarding the
range condition at CCMC and the similarity of communities at Chimney Rock and
CCMC. For the record, grazing has not been excluded at the CCMC site as has
been stated (the cattle have been blamed repeatedly for the lack of growth on
• the topsoil stockpiles), nor has any demonstration of similarity been made
between Chimney Rock and CCMC vegetation communities.
I developed the proposed species diversity criteria based on site-specific
baseline information provided in the permit application and on the capability
of the site (See Table 1.) Upon review of Table 25 (Reclamation Seed Mixture)
approved by the Division, it became apparent that, there was a different
balance in seasonality between baseline communities and the approved mix (see
Table 25). I therefore amend my species diversity success criteria to the
following: the permittee should establish a minimum~~o~,2.coo ~e~~so 's
