NEW ORLEANS—The U.S. Supreme Court has let stand a lower court decision that environmentalists say closed an air pollution loophole for refineries, chemical plants and other major industrial complexes.
On Monday, the high court declined to review a ruling by the Washington, D.C., court of appeals against the Environmental Protection Agency. The court had said EPA went too far in allowing industrial complexes to exceed emissions standards during startups, shutdowns or malfunctions.
Environmental groups, including the Louisiana Environmental Action Network, sued EPA. Jane Williams of the Sierra Club said the Supreme Court had closed a loophole that "has been a get-out-of-jail free card for far too long for dirty industries."
