* Based on Calendar years 1995, 1997, and 1998, which is not suitable for attainment determination (nonconsecutive years)
** Based on Calendar years 1995, 1996, and 1997
***Based on Calendar years 1998 alone, which is not sufficient for attainment determination
Note:
- Designations will be based on 1997-1999 ozone seasons
- Additional counties may be involved in emission reduction strategies
- Nonattainment designations may not follow county boundaries
