8-hr Ozone Design Value Report Based on 1995-97 Data

Information provided for informational purposes onlyNote: EPA no longer updates this information, but it may be useful as a reference or resource.

For the Nation by State and County - Only Counties with Ozone Monitors

This list is based on 1995 to 1997 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.

A Violation is a 8-hr Design Value Greater Than or Equal to 85 ppb

This list is based on 1995 to 1997 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.
