According to traders and sources familiar with plant operations, the five oil refineries located in Los Angeles have come through Hurricane Hilary’s landfall with no damage or loss of operations.

Spot market California wholesale gasoline prices in Los Angeles finished trading with no change from Friday’s close, when it fell 14.5 cents per gallon as the fears over the potential effects of Hilary lessened.

On Monday morning, PBF Energy reported a malfunction at its 180,000 barrel per day (bpd) refinery to regulators in California, however traders said the malfunction was unrelated to Hilary, which passed over the area overnight, after being downgraded to a tropical storm.

A spokesperson for PBF said the refinery activating its safety flare in response to the malfunction was unplanned.

Sources and West Coast market traders said the four other refineries were all operating as per normal. Combined, the five refineries in Los Angeles have a crude oil refining capacity of 1.1 million bpd.

The US West Coast receives its petroleum products and motor fuels primarily from refineries in California and Washington, with additional supplies from Asian imports. The West Coast does not have any pipelines connecting it to major crude oil refining centers in the US Gulf Coast region, or the Middle West region.

Southern California has not been hit by a tropical cyclone like Hilary since 1939.
