On December 20, 2012, the U.S. Environmental Protection Agency (U.S. EPA) finalized changes to the rule (40 CFR Part 63, Subpart DDDDD) regulating existing and new industrial, commercial, and institutional boilers located at major source hazardous air pollutants (HAPs). A major source emits or has the potential to emit more than or equal to 10 tons per year (tpy) of any single air toxic or more than or equal to 25 tpy of any combination of air toxics. The final rule applies to boilers located at major sources that burn coal, oil, biomass, or non-waste materials, but not boilers that burn only gaseous fuels (including but not limited to natural gas, process gas, landfill gas, hydrogen, LPG) and or any solid waste as defined in 40 CFR Part 241. Compliance dates are as follows:

  • Initial Notification of Applicability (available on the IDEM Forms page) due by May 31, 2013 or within 15 days of start up of a new source
  • Existing sources must be in compliance by January 31, 2016 and requirements include:
    1. Energy Assessment
    2. Performance Testing /Fuel Analysis
    3. Work Practice Standards
  • Notice of Compliance Status is due 60 days after the completion of performance testing and/or compliance demonstrations. As of January 1, 2014, the Notice of Compliance Status must be submitted via the Compliance and Emissions Data Reporting Interface (CEDRI) through the U.S. EPA Central Data Exchange (CDX).

Major Source Initial Notification forms must be submitted to:

U.S. EPA Region 5

Boilers with a heat input capacity of 10MMBTU/hr or greater must conduct annual tune-ups.Boilers with a heat input capacity less than 10MMBTU/hr, seasonal boilers, or limited use boilers must conduct tune-ups every two (2) years.

Boiler equipped with an oxygen trim system have a tune-ups frequency of every five (5)years. Boiler tune-ups must include the following:

  • Measure concentrations in the effluent stream of carbon monoxide and oxygen in parts per million (PPM) by volume BEFORE and after adjustments are made to the burner
  • Inspect burner or clean or replace any components as necessary
  • Inspect the flame pattern and adjust the burner as necessary
  • Inspect the air-to-fuel ratio system (Oxygen Trim System) and adjust as necessary
  • Optimize total emissions of carbon monoxide

Energy Assessments are a onetime requirement for existing boilers that were purchased or rebuilt prior to June 4, 2010.
