Kentucky's Attorney General Details "Consequences" of a Hazardous Waste Designation for Fly Ash

I would like to take this opportunity to express my concern regarding recent comments made by the EPA at the 2009 World of Coal Ash Conference. Specifically, Matt Hale, Director of the Office of Solid Waste and Emergency Response, indicated that the EPA is considering proposing regulations the would re-classify ash released from coal-fired power plants as hazardous waste.

Concrete Association Writes EPA on Fly Ash’ Technical and Economic Value

The National Ready Mixed Concrete Association (NRMCA), the trade association representing concrete producers in the United States, is opposed to a potential ruling by the U.S. EPA that would regulate fly ash as a hazardous waste material. Such regulation could have the perverse impact of limiting beneficial uses of the material, therefore increasing wasted stockpiles that pose the very risks that EPA aims to mitigate.

American Concrete Institute Letter to EPA Opposing a Hazardous Waste Designation for Fly Ash

As one of the world’s leading authorities on concrete technology, the American Concrete Institute (ACI) urges the Environmental Protection Agency (EPA) to consider the technical and sustainability implications of classifying fly ash as a "hazardous waste" under subtitle C of the Resource Conservation and Recovery Act (RCRA). It is ACI’s opinion that designating fly ash as a "hazardous waste" will result in little or no fly ash being used in concrete in the US.
