Bonneville Power Administration (BPA) proposes to rebuild its existing 60-mile-long Shelton-Fairmount No. 1 115-kilovolt (kV) wood pole transmission line, which extends from BPA’s Shelton Substation in Mason County, Washington to BPA’s Fairmount Substation in Jefferson County, Washington. The line is the sole point of service for multiple substations/customers west of the Hood Canal including Potlatch Substation, Duckabush Substation, and Quilcene Substation. The Shelton-Fairmount No. 1 line was built in 1949 and is nearing the end of its service life. It is experiencing performance issues due to its age, its poor grounding, and its overall condition. The line needs to be rebuilt to ensure reliable electric service and the safety of the public and transmission workers.
The proposed rebuild project would include rebuilding most of the existing wood pole structures along the line and replacing conductors (the transmission wires), overhead ground-wire, all associated hardware, and disconnect switching facilities. New structures would also be added at some locations along the line, and access roads along the line would be upgraded or repaired where needed to accommodate construction vehicles.
The proposed project would also replace the existing fiber optic cable along about 107 miles of existing BPA transmission lines, including the Shelton-Fairmount No. 1 line. In addition to replacing the fiber optic cable on the Shelton-Fairmount No. 1 line, fiber optic cable would be replaced on existing BPA transmission lines from BPA’s Olympia Substation in Thurston County, Washington to the Shelton Substation, and from the Fairmount Substation to BPA’s Port Angeles Substation in Clallam County, Washington. Access roads associated with the fiber optic cable replacement in the Olympia to Shelton and the Fairmount to Port Angeles sections would be upgraded or repaired where needed to accommodate replacement activities.
The U.S. Forest Service is cooperating with BPA on the environmental review process because about four miles of the transmission line traverse the Olympic National Forest. BPA will work with potentially affected landowners, tribes, federal, state and local agencies, and interest groups to inform the environmental review.
The proposed schedule for the environmental review is as follows:
Comment period March 23, 2022 – April 22, 2022
Draft EA (if warranted) Fall 2022
Final EA (if warranted) Late Spring 2023
Finding of No Significant Impact (if warranted) Late Spring 2023
If decision to build, construction start Spring 2024
