Q (Samuel Hadeed) Tom said earlier this morning that incineration concentrates metals in solids, and Bobtalked about significant reductions of emissions. Are there any regulations on ash as being generated and if there are already concentrated wastes in the ash itself, is this something
that may cause concern? A (Tom Quinn) What I meant was that, you are correct, that metal is being concentrated in the ash. Currently there are no regulations. One of the uses for ash is to put it into landfills as cover. There are no current regulations; I do not believe there
is any at all. It is not a hazardous waste. Typically, in an incinerating operation, ash is hydraulically removed from the furnace and placed into a lagoon where it settles like a rock. The lagoons are dried, and then the material is stacked and taken away to a landfill for cover. There is
no regulation. Some states call it special waste, but those regulations are typically minimal. it is not hazardous waste at all.
