The Trump administration will move Wednesday to repeal federal limits on power plant climate pollution, attacking the Biden era’s most ambitious attempt to use regulations to rein in heat-trapping gases from the electric grid, according to six people familiar with the situation.
Environmental Protection Agency Administrator Lee Zeldin will announce the repeal of the power plant carbon dioxide rule along with a separate regulation to curb hazardous air pollution such as mercury during an event at agency headquarters, the people said.
The two repeal proposals are the most important EPA regulatory actions of President Donald Trump’s second term to date. Without offering details, EPA said Tuesday that Zeldin will make a “major policy announcement” at 2 p.m. Wednesday.
Scrapping the Biden-era power plant rule would effectively shelve regulations for the nation’s second-biggest producer of climate pollution — the electricity sector — which accounts for one-quarter of U.S. greenhouse gases.
