A vegetation fire covering 8 to 10 acres east of Santa Maria in Cat Canyon was contained within about two hours Monday.
The initial size was 6 to 7 acres with a slow rate of spread, Zaniboni said.
Several engines, hand crews and aircraft were assigned to the blaze, which was burning in a relatively unpopulated area.
At 2 p.m., the fire was reported contained, Zaniboni said.
No structures were threatened, he said, and no injuries were reported.
The cause of the fire was under investigation.
