A federal investigation into the October oil spill that paved the Orange County coast has been stalled for several months as authorities await approval to cut, remove and analyze part of the ruptured pipeline.
Coast Guard and National Transportation Safety Board investigators currently have to rely on video captured during underwater pipeline inspections. Without a more detailed forensic examination of the damage in a lab, investigators won’t know whether to continue with their original investigation or move the investigation in a new direction.
It’s not good when bureaucratic processes stall an important investigation. Hopefully the responsible agencies will be sufficiently embarrassed to get the investigation moving.
Per the LA Times, a DCOR pipeline has been identified as the source of a sheen in California State waters near Bolsa Chica State Beach. The pipeline transports oil from Platform Eva. All platform and pipeline operations in the vicinity have ceased.
This will be an interesting case given that the root cause of the leak appears to be anchor dragging and the responsible shipping company has yet to be identified. Also, these informed quotes about leak detection from a previous post are highly pertinent:
“My experience suggests this would be a darned hard leak to remotely determine quickly,” said Richard Kuprewicz, a private pipeline accident investigator and consultant. “An opening of this type, on a 17-mile-long (27-kilometer) underwater pipe is very hard to spot by remote indications. These crack-type releases are lower rate and can go for quite a while.”
The type of crack seen in the Coast Guard video is big enough to allow some oil to escape to potentially trigger the low pressure alarm, Kuprewicz said. But because the pipeline was operating under relatively low pressure, the control room operator may have simply dismissed the alarm because the pressure was not very high to begin, he said.
According to the Coast Guard, investigators determined the ship “was involved in an anchor dragging incident on Jan. 25, 2021 during a heavy weather event that impacted the Ports of L.A. and Long Beach.” The anchor- dragging occurred “in close proximity” to an underwater pipeline later determined to be the source of the October leak that spilled thousands of gallons of oil into the ocean, forcing the closure of beaches and harbors across Orange County.
The hearings and the liability battles that follow will be most interesting. Those lined up to sue the pipeline operator (Amplify), such as this Huntington Beach disc jockey, may have difficulties.
Due to water currents and a robust emergency clean-up effort, local beaches and ocean were re-opened on Oct. 11. By mid October, walking along the wide, sandy beaches there’s no sign of the spill as dolphins and surfers share the waves against a backdrop of cargo ships, oil rigs and the soft silhouette of Catalina Island.
“Right now, there’s high confidence that the spill was approximately 24,696 gallons. The exact number won’t be able to be verified until the investigation has been completed. But there’s high confidence in that number,” Shaye said.
“Our world environment is very resilient, which is a positive thing,” Shaye said. “As far as the birds and wildlife; there have been some deaths, as happens in this kind of situation. But quite a few have been rehabilitated and released back into their environment.
A group of environmental organizations demanded Wednesday that the Biden administration suspend and cancel oil and gas leases in federal waters off the California coast after a recent crude oil spill.
While not the disaster that some had predicted, this spill is another setback for California offshore production. However, cancellation of the remaining producing leases would be a very difficult and costly proposition for the Federal government. At this time, the Beta Unit operator appears to be minimally responsible for the spill, so what would be the basis for cancelling those leases? Cancelling other producible leases would be even more problematic.
This quote from an AP article is consistent with the view expressed here after our review of the inspection reports for the Beta Unit (Platform Elly to shore) pipeline. Further per the AP article:
Safety inspections in 2015, 2017 and 2019 found anomalies in Amplify’s pipeline, including instances of metal loss and three dents that were previously repaired. But several experts who reviewed the reports said the metal loss — which can be a sign of a pipe wall thinning as it corrodes with age — was relatively minor. The dents were not in the same area as the spill.
The 16” oil pipeline was found to be in good condition with no visible damage or anomalies. One (1) CP test point that was installed in 2014 was found to be displaced from its location on the pipeline (this was also noted in the 2018 survey), and no damage was noted at the location (Fix #101).
Aqueos inspection report, May 2020
Pipe‐to‐electrolyte potential values recorded were: ‐ 921 millivolts (mV) on the 6” gas pipeline ‐ 910 millivolts (mV) on the 10” water pipeline ‐ 963 millivolts (mV) on the 10” gross fluids pipeline ‐ 906 millivolts (mV) on the 16” oil pipeline
As the NACE Standard SP0169‐2013 “Control of External Corrosion on Underground or Submerged Metallic Pipelines” criterion is ‐800 mV, all readings indicate that Cathodic Potential is within specifications.

Metal loss data from Baker Hughes internal inspection (12/2019):
The metal loss findings are consistent with those reported in a previous internal inspection (Baker Hughes, 11/2017).
BSEE has general authority to require pipeline inspections under 30 CFR 250.1005. BSEE, the State Lands Commission, and the operator appear to have implemented an effective inspection program for the Beta Unit.
Matt Harty, a 61-year-old retired construction supervisor from the nearby community of Seal Beach, said he was glad to return to the waves in Huntington Beach with other early morning surfers. He said he’s seen oil spills before and this one didn’t seem that bad, and in fact, the beach looks great.
“This is the cleanest I’ve seen the beach in years, right, because there’s been nobody here for a week,” Harty said. “I think they cleaned it up really well.”
While the size of the spill isn’t known, the Coast Guard on Thursday slightly revised the parameters of the estimates to at least about 25,000 gallons (95,000 liters) and no more than 132,000 gallons (500,000 liters).
So far the impact on wildlife has been minimal – 10 dead birds and another 25 recovered alive and treated – but environmentalists caution the long-term impacts could be much greater.

Comment: One gets the sense that some anti-production activists are disappointed that the spill is not the environmental disaster needed to end oil and gas production in U.S. offshore waters, that the pipeline operator is (at most) only partially responsible, and that the primary regulators have been doing their job despite outdated regulations and jurisdictional uncertainty.
So far, two proposed class-action lawsuits have been filed on behalf of a disc jockey who runs beachfront events in Huntington Beach and a surf school that operates in the city known as “Surf City USA.”
