A key Pacific Gas and Electric Co. gas engineer testified that he repeatedly told his bosses the company was relying on flawed data to vouch for the safety of its gas transmission lines before the San Bruno disaster, but that the utility took no steps to fix the problem.
In a civil deposition that attorneys for 350 plaintiffs filed Tuesday in San Mateo County Superior Court, PG&E's Todd Arnett said gas-system managers had ignored his and other employees' concerns that the company was relying on incomplete and inaccurate records contained in its geographic information system.
Legal actions are continuing after the San Bruno explosion and on Sept. 9, 2010 that killed eight people and destroyed 38 homes.
