The WSJ is reporting that California regulators are proposing to require the state's natural gas utilities to undertake safety tests on decades-old pipelines in response to the PG&E explosion that occurred in the fall of last year. "The proposed order, issued late Tuesday, stems from an explosion last September of a natural-gas line owned by PG&E Corp. that killed eight people and destroyed dozens of homes in San Bruno. A federal investigation showed the pipeline, built in the 1950s, had manufacturing defects but had never had a safety test that might have revealed such flaws."
