EPA Boiler MACT Rules

Boiler MACT Rules reminder from Swagelok Energy Advisors

If you operate a coal-fired boiler, an oil-fired boiler, or a biomass-fired boiler, you should be aware of three rules that will regulate facilities considered potential sources of hazardous air pollutants (HAPs). On March 21, 2011, U.S. Environmental Protection Agency (USEPA) published the rules, collectively known as the Boiler Maximum Achievable Control Technology or “Boiler MACT” rules. For many boiler operators the rules will require a one-time assessment, boiler tune-ups every two years, and records and reports in various combinations depending on several factors, including whether you are an “area source” (small source less than 10 MM Btu/hr) or a “major source” (large source 10 MM Btu/hr and greater).
