HUNTINGTON BEACH, Calif. — Officials investigating one of California’s largest recent oil spills are looking into whether a ship’s anchor may have struck an oil pipeline on the ocean floor, causing heavy crude to leak into coastal waters and foul beaches, authorities said Monday.
The head of the company that operates the pipeline said company divers were inspecting the area of the suspected leak that was discovered Saturday, and he expected that by Tuesday there would be a clearer of what caused the damage.
A anchor from a cargo ship striking the pipeline is “one of the distinct possibilities” behind the leak, Amplify Energy CEO Martyn Willsher told a news conference. He said divers have examined more than 8,000 feet (2,438 meters) of the pipeline and were focusing on “one area of significant interest.”
Cargo ships entering the twin ports of Los Angeles and Long Beach routinely pass through the area, Coast Guard officials said. Backlogs have plagued the ports in recent months and several dozen or more of the giant vessels have regularly been anchored as they wait to enter the ports and unload.
“We’re looking into if it could have been an anchor from a ship, but that’s in the assessment phase right now,” Coast Guard Lt. Cmdr. Jeannie Shaye said.
The spill sent up to 126,000 gallons (572,807 liters) of heavy crude into the ocean, contaminating the sands of famed Huntington Beach and other coastal communities. The spill could keep beaches closed for weeks or longer.
The Orange County district attorney, Todd Spitzer, said he has investigators looking into whether he can bring state charges for the spill even though the leak occurred in waters overseen by the U.S. government.
Spitzer also said Amplify’s divers should not be allowed near the pipeline without an independent authority alongside them.
Other potential criminal investigations were being pursued by the U.S. Attorney’s Office for the Central District of California, the Coast Guard and the California Department of Fish and Wildlife, officials said.
Safety advocates have pushed for years for federal rules that would strengthen oil spill detection requirements and force companies to install valves that can automatically shut down the flow of crude in case of a leak. The oil and pipeline industries have resisted such requirements because of the high cost.
“If the operator had more valves installed on this line, they’d have a much better chance at having the point of failure isolated by now,” said Bill Caram with the Pipeline Safety Trust, an organization based in Bellingham, Washington.
The pipeline was built using a process known as electric resistance weld, according to a regulatory filing from the company. That welding process has been linked to past oil pipeline failures because corrosion can occur along seams, according to government safety advisories and Pipeline Safety Trust Director Bill Caram.
