EPA Finalizes Reconsidered Chemical Manufacturing Area Sources (CMAS) Rule

Today, EPA published the final, reconsidered Chemical Manufacturing Area Sources rule (CMAS) in the Federal Register.  Publication ends the reconsideration process, which was launched in February 2010, when the Society of Chemical Manufacturers and Affiliates (SOCMA) and the American Chemistry Council (ACC) filed a Petition for Reconsideration with the agency.  The Petition challenged aspects of the original CMAS rule, which had been finalized in October 2009.  Most recently, EPA had extended the October 29, 2012 compliance deadline for the original rule until December 24 while it completed its work on the reconsidered version.

In the final version of the reconsidered rule, EPA retained the requirement that some synthetic minors have to get Title V permits, a provision which had been vigorously opposed by industry stakeholders.  But the final rule also included changes which industry groups supported, including changes to the Definition of Family of Materials and certain inspection requirements.  The final rule also included an additional 90-day extension of the compliance deadline; existing sources are now expected to comply with the rule by March 21, 2013.  Sources which will now be subject to Title V as a result of the rule have until December 21, 2013 to submit a complete Title V permit application.
