Officials unable to locate source of strong gas smell throughout Alameda County

Alameda County Fire department and PG & E officials were unable to determine the source of a natural gas odor smelled by dozens of residents in Alameda, Oakland, San Leandro and Castro Valley on Saturday.

Dozens of residents in a three-mile radius in the area of Fiji Lane, Remmel Court and Melrose Avenue in Alameda called to report a strong natural gas smell around 7 p.m., said Alameda County Fire Capt. James Colburn. Although emergency responders also smelled the strong odor, they were unable to determine the source, he said.

The smell eventually disappeared. No residents were evacuated and the scene was determined safe and cleared.

But the smell appears to have traveled as it was then reported to have wafted east toward San Leandro and Castro Valley, said PG & E spokeswoman Libby O'Connell.

PG & E continued to investigate the odor using a sensitive gas-detecting equipment. No gas leaks were found

So there you go.
