As previously reported in the HGS Update, on December 20, 2012, the U.S. Environmental Protection Agency (EPA) finalized revisions to a suite of air quality regulations: (i) the National Emission Standard for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers and Process Heaters (Boiler MACT); (ii) the Standards of Performance for New Stationary Sources and Emissions Guidelines for Existing Sources: Commercial and Industrial Solid Waste Incineration Units (CISWI rule); and (iii) the Identification of Non-Hazardous Secondary Materials That are Solid Wastes rule (NHSM rule). The final Boiler MACT has now been published in the Federal Register, lifting the stay of the effective date and making amendments to the Boiler MACT effective April 1, 2013. Further information regarding EPA’s Boiler MACT action is available here. The final joint action on the CISWI rule and NHSM rule has also been published in the Federal Register, with further information available here. In the joint action, EPA lifted the stay of the effectiveness for 40 C.F.R. part 60, subpart CCCC (CISWI constructed after November 30, 1999, or modified or reconstructed after June 1, 2001) and subpart DDDD (CISWI constructed before November 30, 1999). The final amendments to 40 C.F.R. part 60, subpart DDDD are effective February 7, 2013, while the final amendments to subpart CCCC are effective August 7, 2013.
