GOLETA, Calif. (AP) - Slicks of oil that spilled into California coastal waters from an onshore pipeline spanned a total of 9 miles Wednesday, and a company official said the line was operating at full capacity when it broke, suggesting much more oil escaped than initially estimated.
The oil that spilled Tuesday off southern Santa Barbara County formed two slicks, said Coast Guard Capt. Jennifer Williams, one of two federal response coordinators.
Before a morning flyover, the oil was estimated to span 4 miles of ocean.
The spill from a Plains All American Pipeline LP pipe was initially estimated at 21,000 gallons, but officials were not relying on that.
Company official Darren Palmer said Wednesday it remained unknown how much oil actually spilled.
But he said the pipeline was running at a rate of 2,000 barrels an hour - equivalent to 84,000 gallons.
The pipe was built in 1991 and underwent integrity testing a few weeks ago, he said.
Palmer said the company took responsibility for the spill and would pay for the cleanup.
Workers from an environmental cleanup company strapped on boots and gloves and picked up shovels and rakes Wednesday to tackle the gobs of goo stuck to sand and rocks along Refugio State Beach.
The rupture happened on the same stretch of coastline as a 1969 spill that was the largest ever in U.S. waters at the time and is credited with giving rise to the American environmental movement.
Members of the International Bird Rescue organization also were on hand Wednesday to clean any birds that become covered with oil, though none were immediately spotted in the calm seas that produced small waves.
Fan Yang, 26, of Indianapolis, stood on a bluff overlooking the beach, where the stench of petroleum was heavy.
"It smells like what they use to pave the roads," said Yang, who was hoping to find cleaner beaches in Santa Barbara. "I'm sad for the birds - if they lose their habitat."
The broken 24-inch pipeline spewed oil down a storm drain and into the Pacific Ocean for several hours Tuesday before it was shut off.
