The EPA will repeal President Obama’s signature climate change policy the Clean Power Plan and ask for public comments to replace the rule, the New York Times and Reuters reported after reviewing an internal EPA document.

The move would be the first step toward formally scrapping the Obama-era policy, aimed at cutting greenhouse gas emissions from electric power generation.

The EPA also plans to develop a new rule "similarly intended to reduce carbon dioxide emissions from existing fossil-fueled electric utility generating units," according to the document, the Times and Reuters reported.

EPA spokeswoman Liz Bowman declined to comment to the Times on the document or plans for the policy. The document did not provide any details for the possible new rule, the Times and Reuters reported.

Janet McCabe, former head of the EPA’s Office of Air and Radiation under Obama, told Reuters that the process for creating a new rule could take years.

The reports come after President Trump signed an executive order in March directing the EPA to review Obama's climate policy. The rule has remained on hold in federal court as legal battles between states and the agency play out. The D.C. Circuit Court of Appeals had set a deadline for later this month to hear from the EPA on how it plans to proceed with the rule.

Finalized in 2015, the Clean Power Plan seeks to cut carbon emissions by 32% by 2030 compared to 2005 levels. Under the rule, states would develop their own plan to meet the emissions requirements.

Trump has called climate change a "hoax" in the past and taken aim at other Obama-era environmental policies since taking office. In June, he announced the U.S. would withdraw from the Paris climate agreement. The Clean Power Plan was one of the main ways through which the U.S. would have met its requirements under the Paris accord.
