Ozone Implementation
1995-1997 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 1995 to 1997 ozone data (except as noted below). 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 that the list that EPA will use to make designations will be different from this list.

This list is based on 1995 to 1997 ozone data (except as noted below). 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 that the list that EPA will use to make designations will be different from this list.
In a few cases potential nonattainment counties are included on
this list based on less than 3 years of data. In some cases
where monitoring has been discontinued, data from an earlier year
was used. No monitoring site was used which had only one year of
data.
* The county was selected based on 3 years worth of data
showing nonattainment for 1994 to 1996. The historical data
was used because the monitor has incomplete data in 1997.
** The county was selected based on 2 years of data.
