Estimated Emissions from all

(lbs/year) * |
| benzene | 4,500,000 |
| styrene | 3,400,000 |
| formaldehyde | 3,100,000 |
| total PCDD (dioxins) | 139 |
| total PCDF (furans) | 22 |
| total PCB's | 10,962 |
| hydrochloric acid | 1,000,000 |
| hydrogen cyanide | 1,700,000 |
| lead | 1790 |
| mercury | 232 |
| arsenic | 8186 |

*Note: the
factor relating
total dioxins (PCDD - all 210 congeners) to TEQ of dioxin (which considers
only the
17 congeners of TCDD, with a weighing factor applied to each) lies somewhere
between 50 and
100. Thus, the
estimate of 800 grams as TEQ TCDD is comparable with this
calculation
