"The EPA disagreed with a White House request to use current data when revising its rule on mercury air pollution, publicly available email exchanges show, which a law professor says could weaken the agency’s legal defense of the regulation.
The regulation involved a second look at the Obama administration’s legal rationale to see whether it was “appropriate or necessary” for the Environmental Protection Agency to limit mercury and other toxic air pollution from power plants.
The Trump administration’s EPA concluded May 22 the mercury and air toxics standards, known as MATS, which were set in 2012 and met subsequently by the power sector, weren’t justified. It reached this decision by using the same health benefits and compliance estimates used in 2012 to set the standards."
