In another proposed reversal of an Obama-era standard, the Environmental Protection Agency Friday said limiting mercury and other toxic emissions from coal- and oil-fired power plants is not cost-effective and should not be considered "appropriate and necessary."
"It's not unreasonable to expect that if the standards go away there will be some number of utilities that will choose to no longer operate pollution controls that they've installed," says Janet McCabe, former acting assistant administrator of the Office of Air and Radiation at EPA during the Obama administration.
