Ozone Implementation
1993-1995 Counties Not Meeting the 1997 8-hour Ozone Standard
Note: EPA no longer updates this information, but it may be useful as a reference or resource.This list is based on 1993 to 1995 ozone data. Please note that EPA will not designate ozone nonattainment areas until 2000, and these designations will be based on the data that is most recently available at that time. It is very likely the list that EPA will use to make designations will be different from this list.
