LOS ANGELES — A pipeline rupture that spilled an estimated 101,000 gallons of crude oil near Santa Barbara last month occurred along a badly corroded section that had worn away to a fraction of an inch in thickness, according to federal regulators.
The preliminary findings released Wednesday by the federal Pipeline and Hazardous Materials Safety Administration point to a possible cause of the May 19 spill that blackened popular beaches and created a 9-mile slick in the Pacific Ocean.
