CA Methane Gas Leak: Worst Catastrophe Since BP Gulf Disaster

Unstoppable Porter Ranch, CA, methane gas leak being called worst catastrophe since BP Gulf disaster

Methane gas continues spewing, unchecked, into the air over southern California from a fractured well to an underground storage site — at such an alarming rate that low-flying planes have necessarily been diverted by the FAA, lest internal combustion engines meet highly volatile gas and explode. This is, indeed, the biggest environmental catastrophe since the BP Deepwater Horizon oil rig exploded in the Gulf of Mexico in 2010; and for now, there is no way to stop it.

According to the California Air Resources Board, methane — a greenhouse gas 72 times more impactful in the atmosphere than carbon dioxide — has been escaping from the Aliso Canyon site with force equivalent “to a volcanic eruption” for about two months now. So far, the total leaked gas measures somewhere around 100,000 tons — adding “approximately one-quarter to the regular statewide methane emissions” during that same time frame.

“The relative magnitude of emissions from the leak compared to other sources of methane in the State underscores the urgency of stopping the gas leak. This comes on top of any problems caused by odor and any potential impacts from exposure,” states the initial report on the Aliso leak by air quality officials. “The enormity of the Aliso Canyon gas leak cannot be overstated. Gas is escaping through a ruptured pipe more than 8,000 feet underground, and it shows no signs of stopping. As the pressure from the weight on top of the pipe causes the gas to diffuse, it only continues to dissipate across a wider and wider area,” explained Erin Brockovich, who spent time in nearby Porter Ranch investigating the leak. Officials and experts are concerned, and they can’t recall another leak of this magnitude in decades — if ever. “I asked this question of our staff of 30 years,” said Steve Bohlen, who recently left his position as state supervisor of oil and gas.
