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 diethers 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 100° C.

⁵ A type of atom which spontaneously undergoes radioactive decay.
