MACT Parts 1 and 2
Application Information
General Information
Owners and operators of major sources of Hazardous Air
Pollutants (HAPs) in New Mexico need to know about the U.S. Environmental
Protection Agency’s (EPA) promulgation of final amendments to Section 112(j)
of the Clean Air Act and how EPA’s action may affect them.
This section of the Clean Air Act is commonly referred to as the
“MACT Hammer.” Section 112 of
the Clean Air Act covers hazardous air pollutants, or HAPs.
Major sources of HAPs– those that emit 10 tons per year or more of a
single HAP or 25 tons per year or more of combined HAPs – are controlled
through the use of Maximum Achievable Control Technology (MACT).
EPA has been setting MACT standards for a variety of different source
categories during the past 10 years, as required by the Clean Air Act
Amendments of 1990.
Recent amendments to Section 112(j) affect 33 source
categories and make compliance with the Section’s requirements more
flexible. The amendments create a
two-part application process to prepare for the MACT standards that EPA is now
developing for the 33 source categories.
Many of your sources may already have Title V permits issued by the Air
Quality Bureau; if this is the case, the MACT application procedure can be
viewed as an addition to your Title V permit(s). Many of your sources are covered by MACT standards that have
already been promulgated by EPA; if this is the case, you do not need to
complete a New Mexico MACT Application under the MACT Hammer revisions.
For more information on Hazardous Air Pollutants and
sources, visit the EPA’s Air
Toxics Website.
For more background information on EPA’s recent
amendments to Section 112(j), visit their Rule
and Implementation Information page.
