The 10th Circuit Court of Appeals granted a request from the Trump Administration to halt a plan for new pollution controls at Utah's oldest coal-fired power plants.
The court granted the request Monday.
The plan was aimed at reducing haze near several national parks. The court approved EPA administrator Scott Pruitt's request while his agency revises the plan.
The plan called for new equipment to reduce nitrogen oxide emissions at two coal plants in Emery County.
Environmental and clean air groups say the decision rejects EPA's own research, which showed the plan would have cut down haze near Arches and Canyonlands national parks, in addition to other conservation and wilderness areas.
Utah state officials and Rocky Mountain Power said the federal plan would have cost about $700 million — which would have been passed on to customers — without cutting emissions and improving visibility.
