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

[forest444]

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.

Thousands of households have evacuated the area, despite little help, much less information, from the gas company about when they might be able to return. As reported by the Los Angeles Times, SoCalGas spokesperson Michael Mizrahi claimed the company had paid to relocate and house 2,092 households — but that effort is severely lacking, says Los Angeles City Attorney Mike Feuer. Yesterday, the city attorney’s office sought a restraining order to mandate SoCalGas relocate residents in the affected area within 48 hours of their request; and it is also seeking a “special master” to oversee the entire relocation operation, which is currently being handled by the gas company. On Thursday, Los Angeles Unified School District board members voted unanimously to close two Porter Ranch schools and relocate their 1,900 students and staff to different locations for the foreseeable future. A local emergency has been declared by the Los Angeles County Board of Supervisors.

Multiple lawsuits have now been initiated against SoCalGas and/or its parent company, Sempra Energy. A class-action lawsuit has also been filed on behalf of the Save Porter Ranch group; and City Attorney Mike Feuer filed a civil suit earlier this month due to the leak’s continued threat to residents’ health and damage to the environment, alleging failure by SoCalGas to prevent the leak and further exacerbation of the effects.

SoCalGas insists there will be no long-term health effects resulting from the persistent leak; but as Brockovich pointed out, “no one really knows the potential long-term side effects of benzene and radon, the carcinogens that are commonly found in natural gas.” But what’s making this massive leak so difficult to stop pertains to the storage ‘container,’ itself. In fact, there are some 300 such depleted subterranean oil fields being employed this way around the United States. Aliso Canyon, a natural gas storage site since the 1970s, has one of the largest capacities: 86 billion cubic feet.

Beginning December 4th, SoCalGas crews began drilling a relief well to intercept the fissured pipe. Cement will then be poured into both to seal the wells permanently. Flaring, or setting a deliberate fire to burn off excess gas, simply isn’t an option. The mammoth scope of this leak means a flare would ultimately complicate matters even further.

“There is no stone being left unturned to get this well closed,” Bohlen stated. “It’s our top priority.” SoCalGas did have this consolation for affected residents: “We are deeply sorry for the frustration.”
