San Pablo Bay oil sheens were caused by the Phillips 66 refinery or the tanker Yumuna Spirit during transfer operations

RODEO — The mysterious oil sheens that appeared on San Pablo Bay last month were connected to a crude oil tanker or the Phillips 66 refinery, the U.S. Coast Guard announced Thursday night.

An analysis of the oil samples collected during the sheen event on Sept. 20 “matched the light Arabian crude oil cargo being transferred from the vessel Yamuna Spirit to the Phillips 66 refinery,” according to a news release from the U.S. Coast Guard.

Authorities were unable to determine if the sheen found in the bay originated from the Yumuna Spirit of the Phillips 66 facility. The U.S. Coast Guard said the vessel and the facility are responsible for recovering federal related response costs.

The Yamuna Spirit was allowed to complete transfer operations and depart the port after a thorough investigation. The crude oil tanker is owned by Teekay Shipping, an English company, and sails under the Bahamian flag.

The Coast Guard could not determine what caused the odor that sent dozens of people to hospitals in Vallejo with complaints of headaches, nausea and dizziness on Sept. 20.

Tests Show Substance in San Pablo Bay Oil Spill was Crude, More Clues Point to Refinery Tanker As Source

For the first time since two oil sheens were discovered in San Pablo Bay a month ago and a sickening odor sent dozens of people to the hospital in Vallejo around the same time, officials have revealed a clue that could help determine what caused the spill.

Results of tests taken of the substance found in the water in late September show that it was crude oil from the Middle East, according to an official with California’s lead agency for responding to oil spills.

“Tests indicate the product in the water was Arabian Crude,” Amy Norris, a spokeswoman for the state Office of Spill Prevention and Response (OSPR), said in an email.

The office and the U.S. Coast Guard have yet to identify the source or cause of the spill, Norris said.

But Randy Sawyer, chief environmental health and hazardous materials officer for Contra Costa County Health Services, says the crude must have come from an oil tanker at a marine terminal in Rodeo.

“Based on the analysis and where the sheen was located, the oil sheen originated from the ship while it was unloading to Phillips 66,” Sawyer said.

Sawyer said refinery personnel told him the tanker, the Yamuna Spirit, was delivering Arabian Crude shortly before the oil sheens were found.

There were initial indications that the tanker and the refinery could have been tied to the spill. Phillips 66 shut down its marine terminal shortly after the first of two oil sheens were discovered. But Coast Guard and OSPR officials have repeatedly emphasized that their investigation has not been completed.

In fact, on Tuesday OSPR’s Norris confirmed that investigators still do not know how much crude was spilled in the water.

A week after the probe began, the tanker left the region and Phillips 66 reopened its marine terminal.

Phillips 66 declined to comment on the investigation and activity of the Yamuna Spirit at its marine terminal.

“Phillips 66 generally does not comment on activity as it relates to our crude supply and transportation arrangements,” said Aimee Lohr, a refinery spokeswoman.

Officials with Teekay Shipping, which owns the vessel, have not returned requests for comment.

The Yamuna Spirit was reportedly involved in a major spill in Nigeria in February.

Weeks before it arrived in California, the oil tanker was in the Middle East.

The vessel offloaded a portion of its cargo in Southern California days before arriving in Rodeo, according to Gordon Schremp, a state energy commission specialist.

But it’s unclear how the oil might have leaked from the vessel.

“I know that Phillips did check their piping and there were no leaks,” Sawyer said. “There may have been a portion of the piping (that was) not tested.”

When the investigation is concluded, local environmentalists say whoever is responsible should be held accountable.

“The perpetrators need to face stiff penalties for this absolutely unacceptable oil spill,” said Patrick Sullivan, an Oakland-based spokesman for the Center for Biological Diversity.

“But even the steepest fines won’t undo the damage this oil has done to the bay,” Sullivan said. “That’s why we’ve got to move away from shipping dirty crude through California’s fragile coastal ecosystems.”

It’s common for Arabian Crude to make those trips. A significant amount of oil from the Middle East is refined at facilities in the Bay Area and the rest of California.

More than 150 million barrels of crude were imported to the state from countries in the region last year, according to Schremp.
