Coal contains minute levels of fluorspar which are converted to hydrofluoric acid during combustion. These facilities, which began reporting in 1991, accounted for 24% of HF use in 1996. Hydrofluoric acid use in Massachusetts declined slightly, by 5%, between 1990 and 1996. Excluding power plants, who were first required to report in 1991, hydrofluoric acid use declined by 28% between 1990 and 1996.
