Environmental groups Friends of the Columbia Gorge (Friends) and Save Our Scenic Area (SOSA) filed a petition for judicial review in the federal Ninth Circuit Court of Appeals last week challenging a recent decision by the Bonneville Power Administration (BPA) to approve the Whistling Ridge Energy Project’s application to connect to BPA’s energy grid.

The Whistling Ridge Energy Project, proposed by SDS Lumber Company based in Bingen, would be sited near Underwood, Wash. in Skamania County, overlooking the Columbia River Gorge. Proposed are 35 wind turbines, each up to 430 feet high.
