About TRAA

Thank you for visiting our site! We hope you will consider joining us at an upcoming meeting.

The Torrance Refinery Action Alliance is a grass roots organization of South Bay residents and business owners. We formed our group after an explosion at the ExxonMobil Torrance Refinery (now PBF Energy’s Torrance Refining Company) on February 18, 2015 rocked Torrance and the surrounding cities, covering us in ash.

We had many questions. What was in the ash that fell on us and our property? Would it make us sick? Why did the warning system fail so abysmally? Some of us were warned to shelter in place until long after the ash fell.  Others received no warnings at all. Why didn’t the authorities know what to do?

After our initial meetings, we became aware that the refinery still uses a form of HydroFluoric (HF) acid. HF is an extremely deadly chemical that causes respiratory problems, deep chemical burns, and even death. According to ExxonMobil’s own research provided to the EPA, a release of just 5,000 lb of Modified HydroFluoric (MHF) acid could be lethal to residents within a 2 mile radius, and cause serious, irreversible health damage to those in a 3.2-mile radius. More than 250,000 people live in the affected areas. (See our Maps page for more information.)


We hope you’ll consider joining our group to urge elected bodies to ban the use of hydrofluoric acid and modified hydrofluoric acid in our communities. The risk to public health is simply too great.
