Dudash Ff R ~ ~ ~3~~ Environmental Protection Specialist Colorado Division of Minerals & Geology 1313 Sherman Street, Room 2l5 ..:::i~,~,, Denver, CO 80203 Re: Trapper Mining Inc., Permit No. C-81-010 Seed,Mirtures Changes, TechoicalRevisioo TR-74 Dear Mr. Dudash: In accordance with our telephone conversation of February 13, enclosed is a revised seed mixture (fable 1-1) for Range Sites A and 8. The revised mixture reduces th~big sagebrush seeding rate and adds chokecherry and serviceberry. Applicable pages of Tables 3.6-7 and 3.6-9 are also revised and included to reflect a reduction in the allowable sceding rate of big sagebrush from 5.0 l0 3.0 PLS per square foot. Regarding documentation that mountain mahogany was not a significant component of the pro- mining mountian brush plant community (Range Sites A&B), please refer to Section 2.3 in volume 1 of the permit document. Note that moantian mahogany is not even listed in Table 2.3-I (page 2-61) which gives a comprehensive Gst of plant species encountered on the proposed pre-mining permit area. Notice also that it does not appear in any of the other plant community/range site vegetation summary fables in Section 2.3. The enclosed changes should respond to your remaining concerns with this revision application and allow it to be approved. As we discussed, however, I would like to continue a dialogue about the relative merits of certain shrub species and seeding rates for the Range Sites A and B seed mixture. Please contact me if you have Further questions or concerns.
