Abstract
On November 6, 1997, EPA published a rule announcing our finding that the Phoenix, Arizona, metropolitan area had failed to attain the 1-hour national ambient air quality standard for ozone as required by the Federal Clean Air Act (CAA or the Act). This finding resulted in the area being reclassified by operation of law from a ``moderate'' to a ``serious'' ozone nonattainment area. In the rule, we also set a deadline of December 8, 1998 for Arizona to submit the revisions to its implementation plan that are needed to meet the Act's requirements for serious ozone nonattainment areas. In this action, we are extending the submittal deadline to March 22, 1999.
