The Oregon Court of Appeals says Clatsop County can change its mind and block a pipeline that would carry natural gas to an LNG terminal at the mouth of the Columbia River.
The court's ruling Wednesday paves the way for the county to make final its decision against zoning for the Oregon LNG terminal at Warrenton.
The county commissioners approved the pipeline in 2010. Four months later, a newly elected slate of commissioners reversed the decision.
In a lawsuit, the company argued that the first decision was irreversible. The Court of Appeals disagreed.
Local opposition led backers to drop plans for another LNG terminal, upriver from Astoria, in 2010.
A third terminal project, at Coos Bay, remains active.
