Industrial/Commercial/Institutional Boilers and Process Heaters
Announcements:
- 12/21/12: The EPA finalized changes to the National Emission Standards for Hazardous Air Pollutants for Area Sources: Industrial, Commercial, and Institutional Boilers (subpart JJJJJJ), as well as the National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters (subpart DDDDD). For more information, go to: http://www.epa.gov/airquality/combustion/actions.html
- 07/18/12 - The EPA is extending the March 13, 2012 No Action Assurance to apply to the deadline for submitting the Notification of Compliance Status regarding initial tune-ups in the final Area Source Boiler rule. The EPA is also amending the expiration date of the No Action Assurance so that it will run until either the final reconsideration rule is issued and becomes effective or to December 31, 2012. For details, please see Area Source NAA EXTENSION MEMO (PDF).(7pp, 2.0 MB)
- 03/13/12 - The EPA issued a No Action Assurance Letter to establish that we will exercise our enforcement discretion to not pursue enforcement action for violations of the initial tune-up deadlines in the final Area Source Boiler rule. The EPA intends to issue the final reconsideration rule prior to any of the compliance dates for existing sources. For details, please see Area Source NAA LETTER (PDF). (1.2 MB)
- 02/07/12 - The EPA issued a No Action Assurance Letter to establish that we will exercise our enforcement discretion to not pursue enforcement action for violations of certain notification deadlines in the final Major Source Boiler rule. The EPA intends to issue the final reconsideration rule prior to any of the compliance dates for existing sources. The EPA has not identified any new sources that have commenced operation. For details, please see NAA LETTER (PDF). (1.2 MB)
