[1] XCN where X=H or any other group where a formal dissociation may
	 occur
[2] Include mono-and di-ethers of ethylene glycol, diethylene glycol,
	 and triethylene glycol R-(OCH2CH2 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. Ethylene glycol
	 monobutyl ether is excluded from this category.
[3] Includes glass microfibers, glass wool fibers, rock wool fibers and
	 slag wool fibers, each characterize "respirable" (fiber diameter < 3.5
	 micrometers) and possessing an aspect ratio (fiber length divided by fiber
	 diameter) > 3.
[4] A type of atom which spontaneously undergoes radioactive
	 decay.
[5] For this chemical group, specific copounds or subgroups are named
	 specifically in this table. For the remainder of the chemicals in the chemical
	 group, a single
de minimis
value is listed, and this value
	 applies to the sum of the compounds in the group which are not named
	 specifically.
[6] The "toxic equivalen factor" method in EPA/625/ 3-89 -016, [U.S.
	 EPA (1989) Interim procedures for estimating risk associated with exposure to
	 mixtures] should be used for PCDD/PCDF mixtures. A different
de
	 minimis
level will be determined for each mixture depending on the
	 equivalency factors which are compound specific.
[7] The EPA relies on Subparts B and I, and Appendix E of 40 CFR Part
	 61 and assigns a
de minimis
level based on an effective dose
	 equivalent of 0.3 millirem per year for a 7 year exposure period that would
	 result in a cancer risk of 1 per million. The individual radionuclides subject
	 to
de minimis
levels used for section 112(g) are also
	 contained in 40 CFR Part 61.
[8] Emissions from all substances in each set below should be
	 aggregated for the purpose of determining major source status as described in
	 Chaper 2, section 001:

				o-Cresol; p-Cresol
