The U.S. Court of Appeals for the Third Circuit determined in an August 20 ruling that residents neighboring a Pennsylvania coal-fired power plant may sue for property damage even though the plant complies with state and federal rules. The court sided with the two plaintiffs who said fly ash emissions from the Cheswick Generating Station prevented them from fully using their land. A lower court, the U.S. District Court for the Western District of Pennsylvania, previously ruled against the residents, saying their claims were preempted by the Clean Air Act.
