As required by Clean Air Act, in this action, the Administrator will establish the air quality designations for all areas of the United States under the 2015 ozone NAAQS.  The designations "attainment", "nonattainment", or "unclassifiable" are based upon air quality monitoring data and other relevant information pertaining to the air quality in the affected area, including whether an area contains emissions sources that contribute to a violation of the standard in a nearby area. Under the schedule prescribed in the CAA, the Administrator is required to promulgate designations for the 2015 ozone NAAQS no later than  October 1, 2017 , and EPA may extended for up to 1 year in the event the Administrator has insufficient information to promulgate the designations. EPA extended the deadline to  October 1, 2018 . If the Administrator intends to modify any of the designation recommendations previously provided by States or Tribes, he must notify those states or tribes no less than 120 days prior to promulgating final designations and provide them an opportunity to demonstrate why an proposed modification is inappropriate.
