"A coal company has challenged an Environmental Protection Agency (EPA) power plant pollution regulation in court after the agency recently finalized changes that weaken the standards' legal underpinnings.
Westmoreland Mining Holdings sued the EPA in federal court in Washington, D.C., on Friday over its Mercury and Air Toxics Standards (MATS) rule, which regulates the emission of mercury and other toxins emitted from power plants.
The Trump administration last month issued a final rule concerning the standards. The final rule did not change the Obama-era standards but did alter the cost-benefit analysis that justifies them."
