Judges Overturn Bush Bid to Ease Pollution Rules By MICHAEL JANOFSKY

WASHINGTON, March 17 — A federal appeals court on Friday overturned a clean-air regulation issued by the Bush administration that would have let many power plants, refineries and factories avoid installing costly new pollution controls to help offset any increased emissions caused by repairs and replacements of equipment.

Ruling in favor of a coalition of states and environmental advocacy groups, the United States Court of Appeals for the District of Columbia Circuit said the "plain language" of the law required a stricter approach. The court has primary jurisdiction in challenges to federal regulations.
