An outdated piece of pipe that had corroded so much its sides were the width of half a credit card led to the catastrophic explosion and fire at the Philadelphia Energy Solutions refinery in June, according to a new report out Wednesday by the Chemical Safety and Hazard Investigation Board.

Federal investigators said Wednesday that an aging, failed elbow pipe appears to be the initial cause of a June 21 fire and subsequent explosions that injured five people and destroyed part of the processing unit at the largest oil refinery on the East Coast.

Pennsylvania's governor says his administration doesn't plan to spend any state money to help restart a massive Philadelphia refinery shut down since explosions and a blaze damaged it last month.

Democratic Gov. Tom Wolf said Wednesday that his administration is analyzing whether the Philadelphia Energy Solutions Refining Complex can be restarted.

The administration says barriers to getting it back in operation include the fire damage, safety and contamination concerns and competition from more modern refineries.

A fire in a Philadelphia refinery struck by explosions and a pre-dawn blaze last week has now been extinguished as an investigation is launched into what caused it, authorities said.

The blaze at the Philadelphia Energy Solutions Refining Complex, the East Coast's largest oil refinery, was extinguished Saturday afternoon, fire department and city officials said in a statement Sunday. The gas valve that had been fueling the blaze had been shut off and the tank involved in the explosion had been isolated, officials said.
