When Is My Boiler MACT Notification Due?

In a May 18, 2011 Federal Register notice US EPA announced that it was delaying the "effective dates" relative to the Boiler MACT rule for existing sources. Some potentially affected facilities have since been inquiring if this delay mean that potentially affected facilities do not need to submit a notification of applicability by Sept. 17, 2011.

According to EPA, notifications for major sources are not due by September 17, 2011. The agency plans to complete the reconsideration proposal by the end of October 2011 and issue a revised final rule by the end of April 2012. The final rule will include revised compliance due dates, including dates by which facilities will need to submit a notification of applicability.

Notifications for area sources , which includes most smaller sources, are due by September 17, 2011.
