The La Grande City Council has issued a proclamation declaring its opposition to the proposed 300-mile Boardman to Hemingway 500-kilovolt transmission power line, which would pass through Union County and the La Grande area. Idaho Power is leading the effort to get the line built with help from PacifiCorp and the Bonneville Power Administration. It will cost about $1 billion, and two routes are being considered through La Grande, both in the Morgan Lake area.
