MoreThe EPA is making a small change to its anti-backsliding
provisions for the former 1-hour ozone standard under New Source Review.
The proposed action, to be announced in tomorrow's Federal Register would clarify the obligation to retain 1-hour nonattainment new source review (NSR) program requirements for certain areas designated nonattainment for the 1997 8-hour ozone national ambient air quality standard (NAAQS).
The EPA proposes to revise the rule for implementing the 1997 8-hour ozone NAAQS to address how NSR requirements that applied by virtue of the area's 1-hour ozone NAAQS classification should apply under the anti-backsliding provisions of the 1997 8-hour implementation rule.
The rule is a response to the ruling by the U.S. Court of Appeals for the District of Columbia Circuit that the 1-hour major NSR program, as it applies to areas that were designated 1-hour nonattainment on the date of designation for the 1997 8-hour NAAQS, is a required control to prevent backsliding. The EPA has separately proposed to remove the vacated provisions of the rule that allowed states to remove (or not include, if not yet adopted) 1-hour major NSR for nonattainment areas from their state implementation plans (SIPs).
