In addition, the units exceeded several operating limits, such as combustion efficiency and flue gas temperature limits during this period. Limits on carbon monoxide, combustion efficiency, and temperature ensure that good combustion practices are followed.
Poor combustion can result in the formation and emission of toxicants, such as dioxins and furans.
This is a preliminary finding of violations. The company has 30 days from receipt of the notice to request a meeting to discuss the alleged violations and how to resolve them. EPA has concluded that dioxin causes cancer in animals and probably causes cancer in humans. Exposure to high doses can cause chloracne, a severe skin lesion that usually occurs on the head and upper body.
