"Fourteen states — including Oregon and Washington — are threatening to sue the U.S. Environmental Protection Agency for violating the Clean Air Act.

In a letter to the EPA sent Thursday, the group argues Director Scott Pruitt broke the law when he ordered his agency to halt part of the rule-making process for regulating methane and other air pollution from oil and gas facilities.

Last year, the EPA adopted a rule limiting methane and other pollutants from new and modified oil and gas extraction facilities and pipelines. Then, in March, Pruitt stopped the EPA from developing guidelines for existing oil and gas facilities to go along with that rule."
