GOLETA, Calif. -- 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 said Tuesday it's unclear when excavation might begin.
Officials say 10,000 gallons of oily water have been recovered from the ocean as government and volunteer workers clean up along the Santa Barbara County coastline.
Also Tuesday, various federal, state and local agencies briefed the Santa Barbara County Board of Supervisors 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.
25 oiled birds and 18 oiled mammals have been rescued, according to CBS affiliate KCOY-TV in Santa Barbara.
State and federal officials were still seeking volunteers to help with the cleanup efforts.
