The Eugene to Medford Transmission Line is a 146-mile, 500 kilovolt (kV) transmission line between PacifiCorp’s Meridian Substation near Medford and PacifiCorp's Spencer Switching Station south of Eugene.

Review on hold/Operating. On January 2, 2018, the Department received the preliminary Request for Amendment (RFA) #4 to the Eugene to Medford Transmission Line Site Certificate (provided in link below). On February 20th the Department notified the certificate holder that the preliminary RFA is incomplete. The Department requires additional information from the certificate holder before it can find the RFA complete. The Department has put the review of the preliminary RFA on hold until such time that the certificate holder re-initiates review with updated information for Exhibit S..

On October 20, 2022 the certificate folder submitted Exhibit X-2 Wildfire Prevention and Risk Mitigation pursuant to OAR 345-022-0115. The exhibit is added to the pRFA4 documents below and is under review by the Department.

The preliminary RFA requests Council approval for the following primary components: expansion of the site boundary from approximately 23,975 to 24,463 acres; decommissioning of an existing 115 kV transmission line; construction and operation of a new 17.6-mile 230 kV transmission line to be double circuited with the existing 115 kV transmission line; a new 500/230 kV substation (Sams Valley substation); upgrading of the existing Grants Pass substation to accommodate the termination of the new proposed 230 kV transmission line; reconductoring a 4.9-mile segment of existing 230 kV transmission line; and, temporary substantial modification of existing access roads.

The components included in preliminary RFA would be located within Jackson and Josephine counties, and the City of Rogue River. Map
