A federal appeals court has left in place the rule that treats two of the most studied chemicals as hazardous substances under the Superfund law forever, preserving the government's ability to make polluters pay for cleaning them up.
The U.S. Court of Appeals for the District of Columbia Circuit issued the decision on Tuesday, rejecting a challenge brought by seven industry groups led by the U.S. Chamber of Commerce and including the American Chemistry Council and the National Waste and Recycling Association. The three-judge panel was unanimous, and the opinion was written by Judge Patricia Millett.
