A
runaway natural gas leak from a storage facility in the hills above
Los Angeles is shaping up as a significant ecological disaster, state
officials and experts say, with more than 150 million pounds of
methane pouring into the atmosphere so far and no immediate end in
sight. The rupture within a massive underground containment system —
first detected more than two months ago — is venting gas at a rate
of up to 110,000 pounds per hour, California officials confirm. The
leak already has forced evacuations of nearby neighborhoods, and
officials say pollutants released in the accident could have
long-term consequences far beyond the region.
Newly
obtained infrared video captures a plume of gas — invisible to the
naked eye — spouting from a hilltop in the Aliso Canyon area above
Burbank, like smoke billowing from a volcano. Besides being an
explosive hazard, the methane being released is a powerful greenhouse
gas, more potent than carbon dioxide in trapping heat in the lower
atmosphere. Scientists and environmental experts say the Aliso Canyon
leak instantly became the biggest single source of methane emissions
in all of California when it began two months ago. The impact of
greenhouse gases released since then, measured over a 20-year time
frame, is the equivalent of emissions from six coal-fired power
plants or 7 million automobiles, environmentalists say.
“It
is one of the biggest leaks we’ve ever seen reported,” said Tim
O’Connor, California climate director for the Environmental Defense
Fund, a nonprofit group that obtained the video. “It is coming out
with force, in incredible volumes. And it is absolutely uncontained.”
The
gas company has pledged in statements to “execute all possible
efforts” to plug the leak. “SoCalGas recognized the impact this
incident is having on the environment,” company president Dennis V.
Arriola said in a letter last week to Gov. Jerry Brown (D). ). The
company has drilled a relief well while also pouring a brine solution
and other materials into the damaged well in an attempt to seal it,
so far without significant results. The company’s losses in natural
gas alone are estimated in the tens of millions of dollars, with
total damages likely to exceed that figure many times over. A number
of neighbors already have filed lawsuits, part of a growing outcry
that includes calls for the company to close the facility altogether.
The
leak is a setback to California’s efforts to reduce emissions
blamed for climate change. The Brown administration is seeking to
implement the country’s toughest standards on greenhouse-gas
emissions by promoting renewable energy and strengthening measures to
prevent methane from escaping from refineries, pipelines and storage
facilities. –Washington
