UPDATE: Vacaville Gas Main Leak Sealed, Will Take 3-4 Hours to Repair

Update, 12:11 p.m.: PG&E have sealed off the gas leak, but it will take 3-4 hours to repair it, Vacaville City Fire Battalion Chief John Jansen said.

Residents are being allowed back into their homes one PG&E sweeps through them to make sure there is no gas. Until the repair is completed, 20 homes will be without gas.

A gas main break in a Vacaville neighboorhood has prompted the evacuation of 35 homes, according to City of Vacaville Fire Battalion Chief John Jansen.

A city repair crew hit the two-inch gas main while repairing a water leak around 9:30 a.m. on Scottsdale Drive. Twenty-five homes were intially evacuated, Jansen said. He added that the number of evacuations could rise.

"There's potential for it but for now that's the perimeter we have in place now," Jansen said.

One person complained of nausea after the leak but declined medical attention. Jansen said one fire engine and numerous police officers were on scene. A hazardous materials team was not sent to the leak.

"There's no need for hazmat on a gas leak," Jansen said. "The gas will dissipate once PG&E secures it."

Jansen expects PG&E to seal the leak around 11:50 a.m. Monday but that it would take another hour to repair it.
