The U.S. Environmental Protection Agency is moving to bolster its authority to enforce mercury emissions rules for coal- and oil-fired powerplants.
EPA wants to reverse a Trump administration rule that undercut the legal basis to regulate mercury and other pollutants from those plants, and reaffirm public health and environmental benefits of reducing air pollutants through the 2012 Mercury and Air Toxic Standards (MATS), the agency said Jan. 31.
