‚ÄčMcNary-John Day Transmission Line Project
Oregon and Washington (DOE/EIS-0332) 

The McNary-John Day Transmission Line Project was proposed to help integrate power from multiple generation projects being considered in the area. The project involved construction of a 79-mile long 500-kilovolt transmission line.  The line, located next to existing transmission lines, starts at McNary Substation in Umatilla County, Oregon, crosses the Columbia River below McNary Dam, then parallels the north side of the Columbia through Benton and Klickitat counties, and crosses back into Oregon near John Day Dam. BPA completed an Environmental Impact Statement (EIS) that analyzed the potential impacts of the project and released a Record of Decision in 2002. The project was then put on hold due to changing energy market conditions.
In 2008, the need for the line reemerged through a process called Network Open Season (NOS), in which BPA received many new requests for use of transmission lines in the area. To help determine whether to proceed with building the McNary-John Day Transmission Line Project, BPA prepared a Supplement Analysis under the National Environmental Policy Act (NEPA). The Supplement Analysis reviewed the 2002 EIS and assessed whether there had been any significant changes in the project or its environmental impacts. As part of the analysis, BPA sent letters to potentially affected publics requesting comments and held two open house style public meetings. The Supplement Analysis determined that a supplemental EIS for the project is not required, the 2002 EIS remains valid, and no further NEPA documentation was required.
The McNary-John Day transmission line was constructed and the line was energized 2011.
