(Docket# OAR-2002-0058 ) Major Sources

(Docket# OAR-2006-0790 ) Area Sources

The boiler MACT and boiler area source final rules were signed by the EPA Administrator on 

February 21, 2011. A copy of the signed final rules can be downloaded at : 

http://www.epa.gov/airquality/combustion/. On May 18, 2011, EPA published a notice 

delaying the effective date of the major source rule pending the completion of 

reconsideration or judicial review, whichever is earlier. Updates to the status of the rule will 

be provided periodically on this site.
