PACTT.ICORP - 20 I5 IRP UPDATE CI-IAPTER 2 * PLANNING ENVIRONMENT
Segment D and part of Segment E. The agency chose to defer its decision on the western-most
portion of the project looated in Idaho in order to perform additional review o[ the Morley
Nelson Snake River Birds of Prey Conservation Area. Specifically, the sections of Gateway
West that were deferred for a later ROD include the sections of Segment E from Midpoint to
Hemingway and Cedar l{ill to Herningway. A draft supplemental EIS for thc deferred portions of
the project and the Record of Decision is anticipated in 2016.
Gateway South (Segment F): The BLM's Notice of Intent was published in the Federal Register
in April 201l, followed by public scoping meetings throughout the project area. Comments on
this project from agencies and other interested stakeholders were considered as the BLM
developed the draft EIS, which was issued in February 2014. A final EIS and the Record of
Decision is anticipated in 2016.
Sigurd to Red Butte (Segment G): Project construction is complete and the line was placed in
service in May 2015. Sigurd to Red Butte is the third major segment of Energy Cateway to be
constructed, follou,ing Mona to Oquirrh (Segment C) which was placed in service in May 2013
and Populus to Terminal (Segment B) which was placed in service in November 2010.
Boardman to Heminqwav (Sesment H): Energy Gateway Segment H represents a significant
improvement in the connection between PacifiCorp's east and west control areas and will help
deliver more diverse resources to serve its customers in Oregon, Washington and California.
Originally planned as a single circuit 500 kV line l'rom the Hemingway substation south of
Boise, Idaho, to the Captain Jack substation near Klamath Falls, Oregon, PacifiCorp has
continued to pursue alternative joint-development opportunities on other proposed lines west of
llemingway. Idaho Powcr leads the permitting efforts on this project and PacifiCorp continues to
support the permitting efforts under the conditions of the Boardman to Hemingway Transmission
Project Joint Permit Funding Agreement. The Record of Decision is anticipated in 2016 followed
by the Oregon Encrgy Facilities Siting Council's f,rnal order on the Site Certificate,
