The EPA just halted an Obama-era methane rule for oil and gas companies, 4 days before it would have taken effect

The U.S. Environmental Protection Agency on Wednesday halted methane emission standards for oil and gas companies in its latest move to unwind Obama administration climate change rules, amid reports that the United States will withdraw from a global climate change agreement.The agency issued a 90-day stay of the 2016 New Source Performance Standards for the oil and gas industry, which require companies to capture fugitive emissions, obtain engineer certifications and install leak detention devices while it reconsiders the rule.The rule, completed last year under former President Barack Obama, was due to go into effect on June 3.The EPA said it expects to prepare a proposed rule and launch a public comment period after the stay.Environmental groups vowed on Wednesday to block the EPA move in court.
