US EPA will publish a final rule in an upcoming Federal Register placing a “stay” on revisions to emissions standards for chemical manufacturing area sources (CMAS). The stay effectively places the rule on hold.
In January 2012, EPA issued a proposed rule reconsidering provisions in the final National Emissions Standards for Hazardous Air Pollutants for CMAS. The compliance date for the final CMAS rule is October 29, 2012. However, EPA is still in the process of finalizing the reconsideration action and needs more time to complete it. The rule, as found at 40 CFR Part 63, Subpart VVVVVV, will be on hold until 60 days after it is published in the Federal Register.
EPA had originally published the final CMAS rule in 2009, but petitioners asked the Agency to reconsider certain provisions in the rule. The January 2012 proposed reconsiderations include provisions that, if finalized, would revise the applicability of the final rule.
