After speaking with a few EPA employees, I have some follow-up information related to the
Canary in a Coal Mine article from October 6th.
The EPA intends to propose a rule on the status of fly ash by the end of 2009. There are three broad options for what this rule might be:
- All residue of coal combustion may be treated as a hazardous waste.
- All residue of coal combustion may be regarded as non-hazardous.
- A hybrid approach to regulation. For example, disposal may be considered hazardous while some beneficial uses are considered non-hazardous.
Further information about fly ash is available from the Coal Combustion Products Partnership (C2P2).
