MACT Compliance



In May 2013 the Ohio EPA sent a letter to all power generators that fall under MACT Guidelines. The letter stated that there will be no more extensions on compliance. While initial MACT Compliance projected shutdowns were only 9GW of generation would be lost, but quickly estimate went to over 27GW in 2011 and now some studies suggest as much as 72GW will be retired.  it is both  Compliance is both Critical and Urgent

  • History

The Boiler Maximum Achievable Control Technology (MACT) rule applies to new and existing boilers and process heaters at major source emitters of Hazardous Air Pollutants (HAPs). In the context of this rule, major sources are defined as having actual emissions of HAPs in excess of 10 tons per year of any single HAP or 25 tons per year of all HAPs combined. If your facility possess a Title V or Part 70 (Major Source) Air Quality Permit, this does not necessarily mean the Boiler MACT applies to you. A Title V Air Quality Permit signifies that actual emissions of at least one criteria pollutant (e.g. particulate matter, carbon monoxide, volatile organic compounds, etc.) exceed 100 tons per year for non-HAP pollutants, or the 10/25 ton per year HAP thresholds previously stated. If permitted emissions of HAPs are below the major source thresholds, Boiler MACT does not apply to you; however, Boiler GACT may.

On January 31, 2013 the U.S. Environmental Protection Agency (EPA) published in the Federal Register the final rule 40 CFR Part 63: National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters.

Existing boilers will have to complete the following no later than January 31, 2016:

  • Meet the requirements during periods of startup and shutdown.
  • Conduct performance tests to demonstrate compliance with all applicable emission limits.
  • Boiler tune-up
  • Energy Assessment


IPU can help in the following ways:

  1. Meeting EPA’s Compliance requirement by creating a plan ( points to consulting service that produces an Individual Compliance Plan)
  2. Provide an alternative power generation plan that:
    • Optimizes Capital Investment
    • Scalable & flexible to market requirements (up and down)
    • Enables focus on customer acquisition, service, and billing
    • Protects against EPA changes in how they read the law or new Fed or State compliance legislature
