EPA Finalizes 2008 Ozone Air Quality Implementation Rule

Posted Tuesday, February 24th, 2015

On February 13, 2015, the U.S. Environmental Protection Agency (EPA) signed a final rule implementing the 2008 ozone national ambient air quality standards (NAAQS). The final rule establishes submission deadlines for state implementation plans for nonattainment areas; sets attainment dates for each nonattainment area; revokes the 1997 ozone NAAQS for all purposes; establishes anti-backsliding requirements for areas that remain in nonattainment for the 1997 ozone NAAQS; addresses requirements for attainment demonstrations, reasonable further progress emissions reduction plans, reasonably available control technology, reasonably available control measures, nonattainment new source review, and emission inventories; and clarifies attainment dates in light of the D.C. Circuit Court of Appeals’ recent decision vacating previously established deadlines.

EPA previously designated all of Florida as unclassifiable/attainment for the 2008 ozone NAAQS and approved of Florida’s infrastructure implementation plan for the 2008 ozone NAAQS, with the exception of outstanding final action on certain limited elements related to interstate transport. EPA’s final rule for implementing the NAAQS in nonattainment areas will be effective 30 days after publication in the Federal Register, which is expected in the next several weeks.
