Implementation of the 1997 8-Hour Ozone National Ambient Air Quality Standard: Addressing a Portion of the Phase 2 Ozone Implementation Rule Concerning Reasonable Further Progress Emissions Reductions Credits Outside Ozone Nonattainment Areas
EPA is taking final action to revise a portion of its Phase 2 implementation rule for the 8-hour ozone National Ambient Air Quality Standard (NAAQS or standard) for which the Agency had sought a voluntary remand from the U.S. Circuit Court of Appeals for the District of Columbia Circuit. The Court granted EPA's request by remanding and vacating that portion of the rule. Specifically, this rule addresses an interpretation that allowed certain credits toward reasonable further progress (RFP) for the 8-hour standard from emissions reductions outside the nonattainment area.
