Commission staff prepared a Final Environmental Impact
Statement (FEIS) for relicensing of PacifiCorp’s
169-megawatt Klamath Hydroelectric Project, located
primarily on the Klamath River in Klamath County, Oregon and
Siskiyou County, California. On average, the project
generates 716,820 megawatt-hours of electricity annually.
The project occupies 219 acres of lands of the United
States, which are administered by the U.S. Bureau of
Reclamation and the U.S. Bureau of Land Management.
The existing project consists of eight developments, seven
of which are located on the Klamath River. PacifiCorp
proposes to decommission the upstream-most East Side and
West Side developments and to remove the Keno development,
which has no generating facilities, from the project. The
remaining project developments on the main stem of the
Klamath River are J.C. Boyle, Copco No. 1, Copco No. 2, and
Iron Gate. The proposed project also includes the existing
Fall Creek development, located on a Klamath River
tributary.
In this FEIS, Commission staff assessed the environmental
and economic effects of:
- Continuing to operate the project with no changes or
enhancements (no-action alternative);
- Operating the project as proposed by PacifiCorp
(PacifiCorp’s proposal);
- Operating the project as proposed by PacifiCorp with
additional or modified environmental measures (staff
alternative);
- Staff alternative with conditions filed by the
Department’s of the Interior and Commerce;
- Retirement of the Iron Gate and Copco No. 1
developments with additional or modified measures for the
remaining developments; and
- Retirement of the Iron Gate, Copco No. 2, Copco No. 1,
and J.C. Boyle developments, with additional or modified
measures for the remaining developments.
The staff alternative incorporates most of PacifiCorp’s
proposed environmental measures, some with certain
modifications. The staff alternative also includes 25
environmental measures additional to those proposed by
PacifiCorp, including:
- Implementation of an integrated fish passage and
disease management program;
- Implementation of an adaptive spawning gravel
augmentation program in the J.C. Boyle bypassed reach and
downstream of Iron Gate dam.
Based on our detailed analysis of the environmental benefits
and costs associated with the five action alternatives
considered in detail in this FEIS, we conclude that the best
alternative for the Klamath Hydroelectric Project would be
to issue a new license consistent with the environmental
measures specified in the Staff Alternative.
