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: R(OCH2CH)n-OH. Polymers are excluded from the glycol
category.
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.
