Oh yeah, that Chinese drywall: "The coal-ash muck is laden with heavy metals linked to cancer... [but] isn't considered hazardous waste. EPA officials late last year delayed a decision whether to propose reclassifying coal ash as hazardous. Doing so would limit where it could be sent for disposal, possibly increasing the projected $1.2 billion cleanup cost for TVA ratepayers and affecting the ability to recycle the ash into cement and building materials."
