CHP reports a semi truck rolled over on the northbound Highway 99 just south of Houghton Road Sunday afternoon.
The crash was first reported at 3:39 p.m.
Kern Public Heath tweeted an Environmental Health Hazmat team arrived to handle the semi that was carrying 77,000 pounds of biodiesel fuel.
Public Health later said the trailer’s biodiesel load was intact, but did need to clean up 50 gallons of diesel fuel from the truck.
As of 11 p.m. all lanes on the northbound Highway 99 were open.
