The accident appears to be the result of human error. The company was excavating a trench for a water line. The location of the gas line was clearly marked. “They had several options for excavating around the pipeline,” said Charlie Knox, director of Community Planning and Public Works for the City of Benicia. “They were using a very laborious method and thought they had a little more room, but they didn’t”

It sounds as though PG&E crews have gotten the leak isolated and have been able to shut off the supply of gas. Fire officials and PG&E are using instruments to check the gas level in the air. Shortly after the accident happened officials said the gas level was at seven percent and five percent is considered lethal.

PG&E crews arrived on site and estimated it will take four hours to repair the broken four inch high pressure gas line.
Water Line Workers Break Gas Line
Workers excavating a trench for a water line project accidentally broke a high pressure gas distribution line. The city has evacuated businesses and residences in the 100 and 200 blocks of East J, East K and East L Streets.
City Hall and the Post Office have been evacuated and the Emergency Dispatch center has been moved from the police station to the fire station.
Fire Marshal Ray Iverson reported that the damaged line is a four inch plastic high pressure distribution line. “There are two feeds so the break will have to be isolated from both sides,” said Iverson.
Iverson also reported that there was no disruption in 911 emergency dispatch service as it was moved from the dispatch center at the police station to the Emergency Operations Center at the main fire house across from the Solano Square Shopping. “We have a plan in place and we’re executing it,” said Iverson.
Evacuated residents can gather at the Benicia Community Center. According to Iverson, “There are people there to receive them.”
