Coal-fired power plants release more toxic air pollutants such as arsenic and lead than any other U.S. industrial pollution source, says a report Tuesday by the American Lung Association.
The report comes as the U.S. Environmental Protection Agency gets ready to propose rules to address this pollution, which it's required to do by March 16. Environmental and health care groups, including the ALA, are pushing for strict limits on pollutants. The industry seeks more flexibility.
