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.
