The massive natural gas leak in Porter Ranch, CA, just outside of Los Angeles, has been temporarily capped. That’s the good news. The bad news is that the leak isn’t yet permanently stopped and that it has already done incredible damage over the 111 days it spewed methane and toxic chemicals into the air.

The state of emergency called by Governor Jerry Brown is still in effect for what is being named the largest environmental disaster since the BP oil spill. Over 94,700 metric tons of methane has escaped since October 23, which is one of the largest leaks ever recorded. This incident has taken California two steps back in its progress towards greenhouse gas emissions reductions especially since methane is 87 times more potent of a greenhouse gas than carbon dioxide. For perspective, the amount of methane released so far from the natural gas leak will have the same impact on climate over the next twenty years as emissions from seven coal power plants. Despite these environmental crimes, not one person has been arrested, although this past week, the citizens of Los Angeles County have begun taking legal action.

Southern California Gas Co (SoCal Gas), a subsidiary of Sempra Energy, is the responsible company for the Aliso Canyon Methane Leak, and is finally facing charges for this disaster. District Attorney Jackie Lacey announced the criminal charges filed against SoCal Gas for failing to immediately report the gas leak at its Aliso Canyon facility to the proper state authorities. The site leaked for three days before SoCal Gas officials contacted the city’s fire department.

Major public health concerns are also leading to lawsuits. Residents across the county are reporting health issues such as nose bleeds, female health problems (excessive bleeding), rashes, vomiting, headaches, and dizziness, and have packed town hall meetings voicing their concerns. One Porter Rach resident, Christine Katz, stated, “Even though you can’t see the gas, it’s there. And that’s the saddest part — people don’t understand it. Because it’s not a mudslide, it’s not an earthquake. You just don’t see the devastation, but it’s there.”

SoCal Gas has yet to release a full listing of the chemicals being emitted from the leak, furthering distrust and anxiety from the community. Local law firms have organized a website (www.porterranchlawsuit.com) for citizens to reach out if they have been impacted. More than 25 lawsuits have been filed pursuing damages from the SoCal Gas and Sempra Energy. For example, a family of an elderly woman has filed a wrongful death lawsuit against the gas company, claiming that the leaking chemicals led to the worsening of her health and untimely death this past January.

Legal actions will certainly hurt these gas companies financially, but is this an effective way of enforcing the law? History says no. Time and time again, environmental crimes are punished with fines, and these disasters continue to happen putting the public at risk. New regulations, transparency, and stricter criminal enforcement on the individuals responsible very well could bring justice in these incidents.

Crimes committed under a corporate veil are still crimes and should be treated as such. No amount of money will ever reverse the harsh health and environmental effects the Aliso Canyon Methane Leak is having on the region. But we can put into place policies that make corporations take the environmental risks of their operations much more seriously. A proactive justice process would be exponentially more effective means of dealing with environmental crimes than merely reacting after the fact.

satellite-image-of-the-methane-hotspot_1_NASA and University of Michigan scientists have discovered a massive cloud of methane that spans 2500 square miles (about the size of Delaware) located above the the Four Corners intersection of Arizona, Colorado, New Mexico, and Utah.

The atmospheric methane concentration of methane in that area is equivalent to 1.3 million pounds of emissions a year, which is 80% higher than EPA estimates.  This is the largest concentration of methane in the United States.  It was so large in fact that scientists “weren’t sure if it was a true signal or an instrument error,” but they recently verified the levels of methane in the affected area.

Eric Kort of the University of Michigan, Ann Arbor attributed the dramatic methane emissions to leaks in natural gas production and processing equipment in New Mexico’s San Juan Basin.  The San Juan Basin is the most active coalbed methane production area in the US.  The coalbed methane covers the pores and cracks in coal.  As this methane seeps out from underground coal mines, it causes fatal explosions almost yearly.

While the methane concentrations in that area are not an immediate health risk to the local inhabitants, it has significant implications for climate change.  As a greenhouse gas, methane is 86 times more potent in its atmospheric effect than carbon dioxide in the first two decades after release.  25% of human-induced global warming is caused by methane emissions in the environment.

As the U.S. considers transitioning from coal to natural gas as a means of reducing greenhouse gas emissions, it is critical that accurate assessments of leaking methane are accounted for in all calculations.  If leakage of natural gas isn’t greatly reduced, switching fuels may make little or no difference in combating climate change.  This methane hot spot should serve as a warning that other undiscovered leaks are probably out there and having a significant impact.
