The 1990 Clean Air Act (CAA) directs the U.S. Environmental Protection Agency (EPA) to regulate emissions into the air of the following 189 toxic chemicals. These chemicals, called Hazardous Air Pollutants (HAPs), are known or suspected carcinogens, and have high usage and emissions in a wide variety of industries, including printing, metal fabrication, autobody repair, automotive repair, wood finishing, dry cleaning and others. Consequently, the EPA has determined that emissions of these chemicals present a threat to human health or the environment. As an owner or operator of equipment that uses products that contain chemicals, it is your responsibility to determine if your company uses any of the 189 regulated chemicals and whether you are required to adhere to strict controls.

NOTE:
For all listings above that contain the word "compounds" and for glycol ethers, the following
applies: unless otherwise specified, these listings are defined as including any
unique chemical substance that contains the named chemical (i.e., antimony, arsenic, etc.) as part of that chemical's infrastructure.
1 X'CN where X=H' or any other group where a formal dissociation may occur. For example, KCN or Ca(CN)2
2 Includes mono- and di- ethers of ethylene glycol, diethylene glycol, and triethylene
glycol R-(OCH2CH2)n-OR' where n=1, 2, or 3: R=alkyl or aryl groups; R'=R, H, or
groups which, when removed, yield glycol ethers with the structure: R-(OCH2CH)n-OH. Polymers
are excluded from the glycol category.
3 Includes glass, rock, or slag fibers (or other mineral derived fibers) of average diameter 1 micrometer or less.
