Company Making Plans to Excavate Ruptured Santa Barbara Pipeline

Officials from Plains All American Pipeline say they are formulating a site safety plan to excavate the broken section of a pipeline that spilled oil along the California coast.

The company says details of the plan could be released Tuesday, but it's unclear when excavation might begin.

The company is still measuring the spill as it cleans up along the Santa Barbara County coastline.

Meanwhile, various federal, state and local agencies briefed the Santa Barbara County Board of Supervisors on Tuesday about their oil spill response.

Oil blackened area beaches and created a 10-square-mile slick in the ocean after the onshore pipeline ruptured May 19.

Wildlife officials say 13 birds — mostly brown pelicans — and eight marine mammals, including dolphins and sea lions, were found dead.
