Appendix A: Polycylic Aromatic Hydrocarbons (PAHs) and Benzene Emission Reductions

The PAH and benzene emission inventories for the base year 1993, 1997, and 2000 industry commitments are shown in Table I.1 together with the percent reductions in emissions. The emission inventory for the base year was calculated for the SOR based on the best information available at that time. The 1997 emission inventory and the 2000 industry commitments are abstracted from the 1997 companies' submissions to ARET. Since naphthalene is not included in ARET, the naphthalene emissions for 1997 are taken from 1996 NPRI data^{Footnote 25}, which are presumed to be similar to the 1997 emissions. The naphthalene emissions for the 2000 commitments are estimated from the 1996 NPRI data and the companies' commitments for the other PAH species. The benzene emissions are taken from the companies' ARET submissions for 1997 and their 2000 commitments. The emission inventories for both PAHs and benzene include emissions from both the coke ovens and the by-product plants.
