WASHINGTON – President Trump’s environmental chief announced Monday he’ll undo former President Obama’s initiative to reduce emissions by power plants.

“The war on coal is over,” Environmental Protection Agency Administrator Scott Pruitt told coal miners in Hazard, Kentucky.

Pruitt mocked Obama’s effort to stem global warming as a “so-called” plan.

“Tomorrow in Washington, DC, I’ll be signing a proposed rule to withdraw the so-called Clean Power Plan of the past administration and thus begin the effort to withdraw that rule,” Pruitt said.

The Clean Power Plan directed power plants to reduce carbon pollution emissions by a third below 2005 levels by 2030.

But Pruitt says Obama overstepped its legal authority when he tried to limit greenhouse gases.

“Regulatory power should not be used by any regulatory body to pick winners and losers,” Pruitt said. “The past administration was unapologetic. They were using every bit of power, every bit of authority to use the EPA to pick winners and losers on how we generate electricity in this country. And that’s wrong.”

Obama’s order was put on hold last year, when the Supreme Court issued a stay pending the resolution of legal challenges.

Trump signed an executive order on March 28 to formally review the Obama-rule and its legality. Repeal of the regulation on the electric utility plants is the next step.

The action is consistent with Trump’s ongoing efforts to unravel Obama’s environmental protection efforts, including withdrawal of the Paris climate agreement.
