Twenty AGs Supported EPA’s Regulation of Hazardous Air Pollutants from Power Plants

Massachusetts Attorney General Maura Healey led a coalition of 20 attorneys general in comments supporting the Environmental Protection Agency’s (EPA) proposed national emission standards for coal and oil-fired power plants emitting mercury and other hazardous air pollutants. In 2012, EPA issued the Mercury and Air Toxics Standards Rule under the Clean Air Act, which required power plants to significantly reduce their hazardous air emissions. But in 2020, the agency walked back its obligation to control those pollutants. In their comments, the AGs stressed the need for strong regulation of toxic pollutants emitted from power plants that harm human health and the environment, especially for communities that are already disproportionately burdened by pollution.
