EPA met its requirements of the Clean Air Act by signing the most stringent 8-hour standard ever for ozone, revising the standards for the first time in more than a decade. The agency based the changes on the most recent scientific evidence about the effects of ozone, the primary component of smog. EPA Administrator, Stephen L. Johnson, said: "America's air is cleaner today than it was a generation ago." (source: yosemite.epa.gov)
