MACT stands for Maximum Achievable Control Technology. You might be thinking you do not know much more now than when you thought MACT was just some four-lettered acronym that did not apply to you. The Clean Air Act Amendments (CAAAs) of 1994 are responsible for the MACT acronym. As part of the 1994 CAAAs, National Emission Standards for Hazardous Air Pollutants (NESHAPs) were required to be established for approximately one hundred and 188 hazardous air pollutants (HAPs). The basis for these emissions standards was to be the MACT available for the specified HAP. In other words, the limit would be based on the maximum degree of control achievable (a performance-based approach to developing the standard).
