The LAT has an article on the tragic explosion of a PG&E natural gas line late last week. It notes that a "7,481-foot segment of the San Bruno line, farther north, was identified as among the 100 riskiest, according to documents the utility filed with the California Public Utilities Commission. That segment, built in 1948, needs to be replaced because 'the likelihood of a failure makes the risk of a failure at this location unacceptably high,' the documents concluded. The company proposed to spend $5 million to replace it between 2012 and 2014."
