Currently Designated Nonattainment Areas for All Criteria Pollutants

As of November 13, 2009

8-Hr Ozone classified area designations for the 1997 standard were effective on June 15, 2004. Thirteen (13) 8-Hr EAC areas were designated attainment on April 15, 2008.

On June 8, 2007, the United States Court of Appeals vacated the Subpart 1 portion of the Phase 1 Rule (Court Order). The Subpart 1 areas in the Greenbook are listed as "Former Subpart 1" until reclassification of the areas is finalized. Proposed reclassifications were published on January 16, 2009 (74 FR 2936).

Ozone Categorization/Classification Notes

Notes:

The "State(s) Area Name" column contains a common or general name for the nonattainment areas on the row, but may not reflect the exact name of any area on the row. This column cannot be exact since the nonattainment area for one pollutant may not contain the same counties, cities, or states as the nonattainment area for another pollutant on the same row. On a row, mouse over the No. Ctys to see the area name or click on them to see the associated counties. The abbreviations listed in the "State(s)" column reflect all states identified in the row. However, some states on a row may be nonattainment for some pollutants and not for others in the general area.
