Containment lines are "holding" according to a tweet sent Wednesday afternoon by Santa Barbara County Fire Capt. David Sedecki.  By 6:00 p.m. some crews assigned to the fire were sent home.

Employees at the World Minerals business complex were evacuated shortly after the flames broke out.

Most evacuation orders were lifted Tuesday night except for San Miguelito Road, South of Willow. Wednesday morning, all evacuation orders were lifted.

An estimated 1,200 structures were threatened during the fire.  None were damaged.

Trinity Nazzarine at D and North Street was set up as the primary evacuation site Tuesday night.   An evacuation center was established at Lompoc High School for large animals.

Crews used numerous resources including eight air tankers, water tenders and engines from various agencies as well as dozens of ground crews to make aggressive attacks on the flames.
