In response to your request for formal consultation and conference, received on December 1O, 2003, the Service provides the attached Biological/Conference Opinion (BO/CO) which addresses the effects of the proposed license amendments on bull trout (Sah,elinus confluentus) and proposed critical habitat for bull trout in accordance with section 7 of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). The Service concludes in the attached BO/CO that the implementation of the proposed action is not likely to jeopardize the continued existence of the Columbia River distinct population segment of bull trout, and is not likely to destroy or adversely modify proposed critical habitat for bull ~ut. The Service also concurs with the FERC determination that the proposed action, which does not include future projects under the Hatchery Compensation and Tn'butary Conservation Plans, may affect but is not likely to adversely affect bald eagle (Haliaeetm leueocephalus), grizzly bear (Ursus horribilis), and Ute ladies'-tre&~ (Splranthe dilm,lalis) and will have no effect on pygmy rabbit (brachylagus idahoensis), Canada lynx (Lynx Canadens/s), gray wolf (Can/s Jnofflclal FERC-Generated PDF of 20040514-0034 Received by FERC OSEC 05/13/2004 in Docket#: P-2145 -000 lupus), marbled murrclet (Braehyramphus marmoratus), northern spotted owl (Strix occidentalis) or critical habitat for the northern spotted owl, showy stickseed (llakelia venusta), and Wenatchee mountains checkermallow (Sidalcea oregano). Please note that the accompanying incidental take statement includes reasonable and prudent measures and terms and conditions that arc designed to minimize incidental take. If you have further questions about this document or your responsibilities under the Act, please contact Gregg Kurz of the Central Washington Fish and Wildlife Office in Wenatchee at 509-665-3508 cxtension 22.
