Federal Board Wants Hydrofluoric Acid To Be Studied Again

The U-S Chemical Safety Board wants the E-P-A to review a 1993 study on the safety of using hydrofluoric acid while making gasoline.  The explosion at the Husky Energy oil refinery in Superior last April led to the call.  The Environmental Protection Agency is tasked with determining how effective existing regulations are and whether it is viable to use safer technologies at refinery operations.  About one-third of the nation’s refineries still use the volatile chemical.
