LOS ANGELES — A Texas company whose ruptured pipeline created the largest coastal oil spill in California in 25 years had assured the government that a break in the line while possible was “extremely unlikely” and state-of-the-art monitoring could quickly detect possible leaks and alert operators, documents show.
Nearly 1,200 pages of records, filed with state regulators by Plains All American Pipeline, detail a range of defenses the company established to guard against crude oil spills and, at the same time, prepare for the worst should a spill occur.
The company acknowledged the potential for oil to leak from the 24-inch, 10.6-mile-long pipeline west of Santa Barbara. A team of experts organized by the company, however, assessed that risk as remote, according to the records, known as a spill response plan, and were released under the state’s public records act.
“The pipeline and its operation are state-of-the-art,” asserted the analysis submitted to the state. “Spills are still possible, though extremely unlikely.”
On May 19, a 6-inch breach along a badly corroded section of the line caused up to 101,000 gallons of oil to spill, blackening beaches and creating a 9-mile ocean slick. The breach and the environmental damage have challenged the company’s conclusions about safe operation and rigorous monitoring.
