"A coalition of more than 20 health, environmental and racial justice organizations are suing the Environmental Protection Agency (EPA) over a finding that undermines the legal justification behind a regulation for the emission of mercury and other toxins from power plants.

The groups sued the EPA on Friday over the finding that it is not "appropriate and necessary" to regulate certain power plant emissions, which was based on changes to an analysis that justified its Mercury and Air Toxics Standards (MATS) rule.

The Trump EPA did not make any changes to the power plant regulations themselves but did change the cost-benefit analysis behind them to make it appear that the Obama-era rule’s costs outweighed its benefits."
