The Environmental Agency has filed an appeal in federal court to delay its decision on the rule.
The rule would require companies to reduce emissions of methane, a greenhouse gas that is 30 times more potent than carbon dioxide when it comes to warming the planet.
The EPA is seeking an emergency stay of the rule in the Supreme Court.
The agency said in a court filing that the stay request would require it to “prepare a comprehensive environmental analysis” of the proposed rule before it could be issued, and it would ask for an extension of a temporary restraining order.
The order was filed on Thursday in federal district court in Washington, DC.
It was filed with the court’s clerk’s office.
The court is expected to issue its ruling on the stay application sometime later this week.
