An environmental group is suing the Trump administration for modifying Biden-era methane regulations in response to complaints from the oil and gas industry.

The lawsuit filed Monday in federal appeals court in Washington, comes as President Donald Trump’s EPA has embarked on a broader reconsideration of its landmark 2024 new source performance standards and emissions guidelines for existing oil and gas infrastructure. The Environmental Defense Fund, the group behind Monday’s lawsuit, is already challenging those changes in a separate case.

EPA’s modifications at issue in EDF’s new lawsuit allow more natural gas flaring in certain circumstances and alter vent gas monitoring requirements.

“The 2024 methane standards for the oil and gas sector are common sense protections against dangerous air pollution,” said Rosalie Winn, EDF’s senior director and lead counsel for methane and clean air policy, in a statement announcing the new lawsuit.
