Gov. Jerry Brown has declared a state of emergency in Santa Barbara County over the coastal oil spill.
The move Wednesday night from the governor frees up emergency state funding and resources to help in the cleanup efforts.
Also Wednesday, Santa Barbara County District Attorney Joyce Dudley says her office, along with the state attorney general, is investigating the pipeline spill for possible criminal prosecution or a finding of civil liability.
The chairman and CEO of the company, Plains Pipeline LP, says he deeply regrets that the incident happened and apologized to residents and visitors affected by it.
The spill occurred Tuesday about 20 miles west of Santa Barbara. A broken onshore pipeline spewed oil down a storm drain and into the Pacific Ocean for several hours before it was shut off.
