More than 500 gallons of jet fuel spilled onto the road and roadside near the northbound lanes of Interstate 5 just south of Gorman Wednesday morning after a big rig hauling 5,000 gallons of the fuel overturned.

None of the spilled fuel, however, got into the (California) Aqueduct, said Austin Bennett, spokesman for the Los Angeles County Fire Department.

The crash happened about 4:15 a.m. in the northbound lanes of I-5 when the tanker and a pickup truck collided, said Officer Josh Greengard of the California Highway Patrol.

“The Department of Water (Resources) was on the scene,” he said. “But, we were told it (jet fuel) did not hit the water. It was on the right shoulder and in the dirt.”

The big rig driver suffered minor injuries but “did not want to be transported” to the hospital, Bennett said. The pickup truck driver also suffered minor injuries but was not taken to the hospital.

“The call came in as a big rig over the embankment,” Bennett said. “The truck’s tanker was leaking and it was originally thought to be diesel, but it turned out to be jet fuel.”

More than a dozen emergency response vehicles from two Los Angeles County fire battalions, including four hazardous materials crews, responded to the spill.

Officials from Homeland Security and from the California Department of Fish and Wildlife were also dispatched to the crash, Bennett said.

At 6:15 a.m., fire officials at the scene requested three Health HazMat units, he said.

At 10:30 a.m., one of the HazMat units — HazMat No. 150 — was released from the scene.

“About 500 gallons of jet spilled and they tried to dike the leak,” Bennett said, noting it did “not enter the aqueduct.”

In all, between 1,500 and 1,700 gallons of jet fuel escaped from a slow leak on the damaged tanker.

At 7:30 a.m., most of the fuel had been offloaded from the damaged tanker onto a second tanker dispatched to the crash site.

Health HazMat crews were still at the crash site at 11 a.m. assessing the situation, Bennett said.

The No. 4 lane of the northbound I-5 remains closed and is expected to remain closed until about 2 p.m., Greengard said.
