Fact sheet about the change
Part 81 revision (PDF) (15 pp, 116KB)
EPA received nine requests for reclassification to a lower category — a "bump down." No areas requested reclassification to a higher category — a "bump up."
Reclassifying a nonattainment area to a lower classification means that the area is expected to achieve clean air sooner. Moderate areas must attain the 1997 national air quality standards for 8-hour ozone no later than June 2010. Marginal areas must attain no later than June 2007.
This page offers links to the requests, supporting documents provided by the states, and documents produced by the EPA relating to each area.
