Assemblyman Jerry Hill was in San Bruno on Tuesday morning to promote state legislation that would impose stricter regulations on natural gas providers.
Hill, whose district includes San Bruno, held a news conference in the city's Crestmoor Canyon neighborhood to outline the details of Assembly Bill 56, which would require utilities to install automatic shutoff valves on pipelines in highly populated areas.
The Crestmoor Canyon neighborhood was the site of the PG&E gas pipeline explosion on Sept. 9, 2010, that killed eight people and destroyed 38 homes. It took PG&E more than 90 minutes to shut off the flow of gas that day.
The proposed law is scheduled to be voted on in the state Assembly on Friday, the first anniversary of the explosion.
The new law would also require that gas companies submit plans for comprehensive testing of their transmission systems to state regulators.
