Background. Burning coal produces a variety of solid wastes known as coal combustion waste or coal combustion products. These include coal ash (fly ash and bottom ash), boiler slag, and flue-gas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other applications.

It is important to realize hexavalent chromium has its own threshold limit value (TLV) that may be lower than other components present as airborne contaminants. Remember that hexavalent chromium is usually only a percentage of the dust fume and mist generated, and other processes will produce fume containing small amounts of hexavalent chromium.
