If a Compact areas deferral is ended, and its nonattainment designation for the 8-hour standard becomes effective, when will conformity apply?
If a Compact area’s deferral is ended, conformity for the 8-hour standard will apply one year after the effective date of the designation. For example, if a Compact area misses a milestone and its deferral ends, and its 8-hour nonattainment designation becomes effective on September 30, 2005, conformity under the 8-hour standard would apply on September 30, 2006.
