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.
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.
