Pacific Gas and Electric (PCG) released a list of 100 high priority gas lines in California, 11 days after a gas main exploded in San Bruno, killing at least four people.
PG&E compiled the list using criteria including potential for corrosion and the potential for third-party damage such as construction, the company said on its website.
The pipeline in San Bruno was not on the Top 100 list, company President Chris Johns said. It is still not known what caused the explosion in San Bruno, which sent flames shooting high into the air and consumed homes and cars while residents fled for their lives.
"We were not aware of anything in this particular area that would have met the criteria to put it on that list," Johns said, according to NBC.
