Air contaminant potential (MACT standards have substantially reduced dioxin, WTE 19% of Hg emissions in 1995 – 90% reduction since then)

Public disapproval
Risk imposed rather than voluntary
Incineration will decrease property value (perceived not necessarily true)
Distrust of government/industry ability to regulate
