* Coal-tar-pitch Volatile's standard is exceeded only if the following conditions are met:
1. The volatile emissions are from distillation residues of coal, petroleum, wood, or other organic matter, and
2. Volatile emissions are found to contain more than 0.2 mg/M3 of benzene-soluble material and
3. Laboratory analysis by mass spectrometry of the benzene-soluble fraction confirms the presence of benzo(a)pyrene and/or one or more of five additional fused polycyclic hydrocarbons: anthracene, acridine, pyrene, chrysene and phenanthrene.
