THE DANGER

“Modified” hydrofluoric acid (MHF) is a dangerous industrial chemical used in massive quantities in only two California refineries, Torrance and Valero, Wilmington. If released, it forms a ground-hugging cloud that can drift for miles, causing death and injury. The refineries’ other mitigation measures, like water sprays and barriers, are also ineffective. Mass casualties can result from an MHF release — wind direction determines who dies.

 

Results of 2015 explosion that nearly released 50,000 lbs of MHF, which could have killed or injured tens of thousands, according to the U.S. Chemical Safety Board

WHAT’S BEING DONE

For decades, the South Bay has battled the refineries’ all-too-successful campaign to keep using MHF rather than converting to a much safer process, such as is used at Chevron in El Segundo and the other California refineries. Following the massive Torrance refinery explosion in February 2015, which nearly released 50,000 lb of MHF, investigations by TRAA and the U.S. Chemical Safety Board uncovered the true threat MHF poses. Now, the South Coast Air Quality Management District (SCAQMD) is considering Rule 1410 to require MHF/HF replacement with a safer alternative at both refineries. But industry is fighting back with well-financed campaigns.
