Antonio Ornelas Velazquez was taken into custody by Cal Fire peace officers on Saturday. He faces two counts of involuntary manslaughter and one count of unlawfully starting a fire causing bodily injury.
Investigators said the garbage truck driver dumped a burning pile of trash on the side of the road before flames ignited a wildfire that ultimately spread to about 1,000 acres. Dashcam video released by authorities shows the truck pulling over as smoke rises from its payload.
Winds blew the fire into a mobile home park, and two people later died in the blaze.
Seventy-two structures, including dozens of homes, were also destroyed.
