HUNTINGTON BEACH – Firefighters are investigating the spill of a reported 1,040 gallons of fuel from a tanker truck Wednesday at the Chevron terminal in Huntington Beach.

The 8,000-gallon capacity tanker truck was receiving fuel when it ruptured around 6:15 a.m. Wednesday, Sept. 27, at the terminal, according to the Huntington Beach Fire Department. The truck began leaking.

The terminal’s fire suppression system was activated before the fire department arrived and covered the area with foam, said Capt. Steven Teasdale. The station on Gothard Street also shut down automatically.

Firefighters used hose lines with foam and water to suppress the vapors and prevent a fire, Teasdale said.

The department’s hazardous materials team helped stop the leak and the truck was emptied of its remaining fuel.

No one was injured.

What caused the truck – which is not owned by Chevron – to rupture is still unknown and is under investigation. There was no threat to the environment, Teasdale said.
