U.S. District Judge Scott Skavdahl issued a temporary halt on new federal rules on hydraulic fracturing on public lands. The stay, which expires July 22, had been requested by energy industry groups and several states.

The rules, which had been set to take effect on June 24, would require companies to disclose information on chemicals used in fracking. They would also impose new rules to prevent leaks from oil and gas wells.

Still pending before Judge Skavdahl is a request for a preliminary injunction blocking the rules. A hearing on that request is not expected until mid-August, according to the IPAA.

Those seeking the injunction include the Independent Petroleum Association of America, the Western Energy Alliance and the states of Colorado, Wyoming, North Dakota and Utah. The states argue that the rules would infringe on their sovereign authority to regulate hydraulic fracturing.

“We are pleased the court agreed that the new BLM regulations present serious and difficult questions that justified a stay of these rules’ effective date,” Colorado Attorney General Cynthia Coffman said in a statement.
