Preventing Future Aliso Canyon-Sized Gas Leaks – the Importance of Well Integrity

By Scott Anderson / Published: January 28, 2016

AlisoCanyon4 Southern California is now in month three of one of the country’s worst environmental disasters. In October 2015, a natural gas storage well operated by SoCal Gas sprung a massive leak hundreds of feet underground, releasing nearly 1,400 tons of gas into the air each day at its peak. Thousands of local residents impacted by noxious fumes and oily mist have been evacuated from the communities around the Aliso Canyon storage field. Because the leak is so large and technically complex, SoCal Gas has been working for months to fix it – so far without success.

In January, California Governor Jerry Brown declared a State of Emergency because of the ongoing leak. In addition to addressing the immediate disaster at Aliso Canyon, Gov. Brown ordered emergency regulations for the state’s natural gas storage industry and has directed several state agencies and commissions to prepare and submit reports and propose how to prevent similar leaks at similar sites across the state.

2016 Starts With Growing Momentum To Cut Oil And Gas Methane Pollution

By Felice Stadler / Published: January 27, 2016

Logo_PDD_2016.svg (1) We’re less than a month into 2016, and there are already signs that this could be the year the United States finally gets serious about addressing methane pollution from the oil and gas industry.

Some strong first steps in 2015 got the ball rolling, and now attention-grabbing events like the massive methane leak in Southern California and the announcement that 2015 was the warmest year on record are opening people’s eyes to the urgency of tackling this potent climate-forcing pollution.

Great Strides Made in 2015

Many important first steps to curb oil and gas methane pollution were taken in 2015, most notably, the Obama administration setting a goal of reducing this pollution 40 to 45 percent by 2025. To help achieve this goal, the U.S. Environmental Protection Agency (EPA) in August proposed a national methane emissions standard for newly built oil and gas sources. Read More »

Pennsylvania Announces Plan for Strongest Methane Rules in the Nation

John Quigley, Secretary of Pennsylvania’s Department of Environment Protection, joins Cindy Dunn, Secretary of the Department of Natural Resources and Pennsylvania Governor Tom Wolf at a Facebook town hall event Jan. 19 to announce plans to regulate methane emissions from the state’s oil and gas industry.

Pennsylvania leaders have a duty to protect Keystone residents from oil and gas pollution. Fortunately, Governor Wolf and the Pennsylvania Department of Environmental Protection took an important step in that direction this week when they released a blueprint for cutting methane pollution from the natural gas industry.

“The goal here is to cover not only new sources of methane and VOC emissions [from oil and gas facilities], but also existing sources over time,” DEP Secretary John Quigley told hundreds of viewers during a live Facebook town hall event yesterday. “We want to have a comprehensive emissions program that is nation-leading. I think it’s the strongest set of provisions in the country, and I think the number two natural gas producing state in the nation should have the best regulations. That’s what we’re going to have in Pennsylvania.”

That’s a bold and laudable commitment – one that deserves our support to help make sure the promise becomes reality. Read More »

The California Gas Disaster: What Comes Next and Where Else Could it Happen?

By Mark Brownstein / Published: January 14, 2016

The ongoing leak at the Aliso Canyon natural gas facility owned by Southern California Gas has driven more than 2,000 families from their homes in the Porter Ranch area of Los Angeles and prompted Gov. Brown to declare a state of emergency. It’s dumped an estimated 83 thousand metric tons of methane into the atmosphere so far (see our leak counter here), with no clear end in sight.

But what are the next steps from here? What are the wider implications of this continuing disaster; and where else could something like this happen? What do we do to prevent another Aliso, and how will Southern California make up for the environmental damages once the leak stops?

The troubling fact is that Aliso Canyon is just the tip of a very big iceberg, reflecting both the industry’s widespread methane problem, and the potential local risks of over 400 other storage facilities nationwide. It spotlights a longstanding, largely invisible problem, promising to shift political dynamics around solutions. And the penalty phase, when it comes, will hopefully codify important principles that will also have a big effect on industry behavior. Read More »

In California, Electric Vehicles are the New DeLorean in ‘Back to the Future’

By Larissa Koehler / Published: December 28, 2015

As any child of the ’80s knows, October 21, 2015 is “Back to the Future Day” – the day that the film’s protagonist, Marty McFly, travels to the future in his DeLorean. Though it would no doubt be useful to have access to flying cars (think of the traffic one could avoid), Californians are seeing increased access to something more practical: electric vehicles (EVs).

In order to meet the state’s greenhouse gas (GHG) reduction goals, emissions from transportation – the sector most responsible for harmful pollution – need to be addressed. Enter Governor Brown’s zero-emission vehicle (ZEV) mandate, which aims to build enough infrastructure statewide to support one million clean vehicles by 2020, and put 1.5 million ZEVs on the road by 2025. With this executive order, we have a much better chance of ensuring a low-carbon future and effectively combatting climate change in California. Read More »

Infrared Camera Reveals Huge, Wafting Cloud of Methane over California’s Aliso Canyon

By Tim O'Connor / Published: December 10, 2015

Methane pollution from the oil and gas industry is a serious problem for our climate and communities, but it’s one most people aren’t even aware of. That’s because, while methane is a powerful pollutant, it is colorless, odorless and invisible to the naked eye.

But residents of Southern California’s Porter Ranch neighborhood had their eyes opened wide to the methane problem when a natural gas storage well in nearby Aliso Canyon ruptured and created a massive leak right next to their homes – an incident detected by residents in October from the putrid smell of mercaptan, an additive utilities use to more easily detect natural gas leaks.

Natural gas is made mostly of methane, and when it is released unburned, it has a warming power over 84 times that of carbon dioxide over 20 years. So, leaking or intentionally emitting unburned natural gas – which happens not just through malfunctions but often during routine production and transportation of oil and gas – can do major climate damage. The California Air Resources Board estimates that Aliso Canyon is pumping out methane at about 50,000 kg per hour, or about 62 million standard cubic feet, per day – that’s the same 20-year greenhouse gas impact as the daily emissions from 7 million cars.

Now, on day 48 in a very uncertain timeline of the one of the largest U.S. natural gas leaks ever recorded, infrared cameras are giving us a true glimpse at the size of this man-made methane volcano. Looking at side-by-side images of Aliso Canyon taken on Dec. 9 using an everyday camera and one equipped with infrared technology reveals just how blind we are to this kind of pollution:
