Emissions

Chemical Emissions
There has been a significant reduction in chemical emissions since the baseline year of 1994. The reduction trend in chemical emissions can be attributed to a variety of factors and emission reduction projects.

Reason for change: EPA required reductions due to Cellulose MACT standard implementation.

Emissions of Priority Compounds
Louisiana Operations met the company target on this critical 2005 EHS goal five years earlier than expected by reducing priority compounds by more than 75 percent since the baseline year of 1994.

Reason for change: Regulatory mandated change to a new calculation methodology issued by EPA resulted in increased actual emissions being reported this year.

Emissions of Volatile Organic Compounds (VOC)
There has been a significant reduction in actual Volatile Organic Compound emissions since the baseline year of 1994.

Reason for change: EPA required reductions due to Cellulose MACT standard implementation.

CO₂ Emissions per Pound of Production
Reason for change: Increased Start-up and shutdown flaring at LHC III resulted in increased flaring waste and reduced production.

Dioxin Emissions — Air and Water
Air: Reduction in 2005 – all units operated at comparable to even better performance versus 2004.

Water: Process variability; WWTP (Vinyl Oxy waste water contribution) slightly up, Vinyl- and Chlorine-outfalls lower than 2004.

Dioxin On-Site Landfill — Disposal
Landfill: TEQ down significantly from 2004, less Chlorine cell waste disposed.

Dioxin Treatment — On-Site Destruction

Treated: Lower Oxy-EDC production rates (tars burned) are compensated by higher disposal rate of Oxy waste water solids (candle filters and a tank cleaning event). The extreme TM-17/TEQ ratio of these solids caused the increased TM-17 number.
