Gas price spikes blamed on shutdowns, but report indicates plants online

WASHINGTON -- West Coast gasoline price spikes in May and October were widely blamed on idled refineries, but new research to be released at a hearing today shows that refiners continued to produce gasoline in periods when the public was told the contrary.

The information comes from Oregon-based McCullough Research, which combed through thousands of pages of environmental documents to conclude that refineries were in fact operating during supposed shutdowns.

Specifically, the report alleges that in May, at a time when Royal Dutch Shell's Martinez plant was reported to be down for maintenance for two weeks, it appears to have been making gasoline for at least half that time. That conclusion is reached from state environmental documents showing nitrogen oxide emissions had returned to normal at the refinery a full week before it was reported to have come back on line.

Similarly, Chevron's Richmond refinery was reported down for maintenance for two weeks in May, but emissions data suggests the refinery never ceased operation.

The research also concludes that gasoline inventories actually were building in May during a time in which West Coast motorists paid at least 50 cents more per gallon than the national average. This inventory building, evident in data from the California Energy Commission, happened even as four refiners were supposedly down for some portion of May.

At the time, media reports, citing analysts and industry officials, blamed the price hikes on maintenance shutdowns.

But the shutdowns, which energy companies said had been planned long in advance, have not traditionally happened in May, the research showed, in part because it is a high-demand month for gasoline usage.

The October price spike, which mostly affected California, was shown by the research to be about 66 cents higher per gallon of gasoline than should have been the case based on historical patterns of oil prices and gasoline inventories.

"This is an environment where market power, defined as the ability of a few producers to set prices outside of market forces, is likely to exist," Robert McCullough said in a report that he will formally present today during a hearing in Sacramento on California's refineries. His access to state regulatory data was aided by a push from the office of Sen. Dianne Feinstein, D-Calif.

The hearing will be held by the state's Senate Select Committee on Bay Area Transportation.
