The U.S. Environmental Protection Agency on Friday reaffirmed the basis for a rule that requires “significant reductions” in mercury and other harmful pollutants from power plants, reversing a move late in former President Donald Trump's administration to roll back emissions standards.
The EPA said it found it “appropriate and necessary” to regulate emissions of toxic air pollution under the Clean Air Act, setting the stage to restore protections enacted when President Barack Obama's EPA issued the Mercury and Air Toxics Standards.
