Three other listed species, Black-footed ferret(Mustela nigripes), Canada lynx (lynx <br /> canadensis), and Mexican spotted owl (Strix occidentalis lucida), were analyzed in past <br /> consultations between OSMRE and the Service on Trapper Mine activities (see 1.2 Consultation <br /> History in BA). OSMRE had determined that there would be no effect to those three species. <br /> OSMRE found past analyses to be adequate and did not reanalyze effects to those species in the <br /> current BA. <br /> Below,the Service has prepared a BO with a finding that the proposed project is not likely to <br /> jeopardize the four endangered fish,nor is it likely to destroy or adversely modify their critical <br /> habitats (attached). We also concur(below)with OSMRE's determination for the western <br /> yellow-billed cuckoo (cuckoo) and its proposed critical habitat. <br /> For the Dudley Bluffs Twinpod, Ute ladies'-tresses, black-footed ferret,Mexican spotted owl, <br /> and Canada lynx,we acknowledge your determination of no effect, but neither 7(a)(3) of the Act, <br /> nor implementing regulations under section 7(a)(2) of the Act require the Service to review or <br /> concur with this determination; therefore the Service will not address these species further. <br /> However,we do appreciate you informing us of your past and current analyses for these species. <br /> Concurrence for western yellow-billed cuckoo and its proposed critical habitat <br /> No cuckoos have been found at the Trapper Mine or the Craig Generating Station (Craig <br /> Station), both of which lack cuckoo habitat. Cuckoo habitat is present approximately 1.5 miles <br /> to the northwest of the Craig Station along the Yampa River. Critical habitat has been proposed <br /> for the western yellow-billed cuckoo (79 FR 48547), including a unit along the Yampa River <br /> between the towns of Craig and Hayden. Cuckoos and their proposed critical habitat are found <br /> within the airshed analyzed for mercury deposition from the Craig Station, as outlined in the BA <br /> and discussed in our BO below. <br /> We have records of only six cuckoos from the Yampa proposed critical habitat unit. The most <br /> recent observation was from 2015. We do not know whether any of these cuckoos were nesting <br /> or not. There is potential for contamination of cuckoo insect prey items and habitats from <br /> mercury emissions from the Craig Station. However,we have no data on mercury levels from <br /> cuckoos or their prey in this area. Aquatic insects are more likely to accumulate mercury from <br /> the environment than terrestrial insects due to the mercury methylation process which takes place <br /> in the presence of anoxic lentic environments (Sandheinrich and Wiener 2011). Aquatic insects <br /> (e.g., dragonflies, caddisflies) are only a minor component of a cuckoo's diet(79 FR 48587). <br /> As described in the BA (Appendix B), in order to further our collective knowledge regarding the <br /> use of the Yampa proposed critical habitat unit by yellow-billed cuckoos, Trapper Mining Inc. <br /> (Trapper)plans to commit$5,000 for a yellow-billed cuckoo survey during the breeding season <br /> within the recently proposed critical habitat unit along the Yampa River. Trapper would either <br /> conduct the survey itself or hire a contractor to perform the survey (in either case the official <br /> survey protocol would be followed by a qualified permit holder). The results of the survey will <br /> be provided to the Service. <br /> You have determined that your proposed action may affect,but is not likely to adversely affect <br /> the cuckoo. You have also determined that your proposed action is not likely to destroy or <br />
