A letter sent by Oklahoma Attorney General Scott Pruitt and 12 other states to the federal EPA expressing concern that the EPA not settle a threatened lawsuit from several northeastern bully states over the EPA's program to regulate methane emissions in shale fracking. The EPA backed down from those regulations when it was shown their methodology is inaccurate. States like New York and Rhode Island have threatened a lawsuit to force the EPA to regulate under the Clean Air Act. Oklahoma and other states are saying if EPA settles that lawsuit and starts regulating, they'll have a new lawsuit to content with.
