"A coalition of public health and environmental groups filed a petition for review Monday, arguing the EPA’s recent move to weaken power plant emission rules endangers people’s health and lives.

The Environmental Protection Agency’s February rollback of its Mercury and Air Toxics Standards (MATS) rule “will expose more communities to mercury and other toxic pollutants, leading to brain development impacts, asthma attacks, cancers, and premature deaths,” Harold Wimmer, president of the American Lung Association—one of the litigants in the case—said in a statement.

“Our mission is to save lives, and we are taking this action because EPA has retreated from their mission and is putting Americans at risk,” Wimmer said.

The case was filed in the US Court of Appeals for the District of Columbia Circuit."
