"Gas Blasts Spur Questions on Oversight"
A 2008 natural gas explosion that killed a man in Sacramento "was one example of what many experts and studies say is weak oversight of gas pipelines in the United States, a problem that has contributed to hundreds of pipeline episodes that have killed 60 people and injured 230 others in the last five years. Those figures do not include the final toll of the explosion of another Pacific Gas and Electric pipeline this month in San Bruno, Calif., that left seven people dead and more than 50 injured."
