National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial & Institutional Boilers and Process Heaters


Section 112 of the Clean Air Act (CAA) outlines the statutory requirements for EPA's stationary source air toxics program. Section 112 mandates that EPA develop standards for hazardous air pollutants (HAP) for both major and area sources listed under section 112(c). This regulatory action will finalize emission standards for boilers and process heaters located at major sources. Section 112(d)(2) requires that emission standards for major sources be based on the maximum achievable control technology (MACT). Industrial boilers and institutional/commercial boilers are on the list of section 112(c)(6) source categories. In this rulemaking, EPA will finalize standards for these source categories.
