[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 compounds 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 equivalent 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:

Cresols/Cresylic acid (isomers and mixture); m-Cresol; o-Cresol; p-Cresol
