The San Francisco gas pipe explosion last week along with an oil pipeline leak near Chicago is likely to draw regulators’ attention to fuel transportation networks, some of which have been in service more than four decades.
Four people are confirmed dead and four are missing after the Sept. 9 explosion of a 54-year-old PG&E Corp. natural-gas pipeline in the San Bruno suburb. The blast happened one day after an Enbridge Inc. crude-oil line leaked near Chicago, forcing a shutdown threatening fuel supplies in the U.S. Midwest. The Enbridge pipe, which can handle 670,000 barrels a day, started service in 1968.
