Officials at Oakland International Airport were investigating a possible jet fuel leak Monday evening that could reach San Francisco Bay.
An airport employee smelled fuel near a group of tanks close to Terminal 2 on Monday afternoon, airport spokesman Robert Bernardo said.
Officials were continuing to investigate the odor and whether fuel had leaked from any tanks.
Bernardo said the fuel leak could reach the Bay because the tanks are near a retention pond that filters storm water into the Bay.
An absorbent boom has been placed in the pond as a precaution to help contain any fuel that may have leaked.
U.S. Coast Guard Petty Officer Russell Nagle said an incident management team did not spot any fuel in the Bay on Monday afternoon.
