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:
(OCH2CH)n-OH. Polymers are excluded from the glycol category.
The substance ethylene glycol monobutyl ether (EGBE, 2-Butoxyethanol) (CAS Number 111-76-2) is deleted from the list of hazardous air pollutants.
3 Includes mineral fiber emissions from facilities manufacturing or processing glass, rock, or slag fibers (or other mineral derived fibers) of average diameter 1 micrometer or less.
4 Includes organic compounds with more than one benzene ring, and which have a boiling point greater than or equal to 100º C.
5 A type of atom which spontaneously undergoes radioactive decay.
NOTE: For all listings above which 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.
