As a major producer and consumer of oil and gas, California can set the bar for reducing methane leaks. And today, the Golden State showed it’s up to the challenge, making a critical change in proposed rules aimed at cutting methane pollution from oil and gas wells, pipelines and equipment of the like – now putting California firmly on the path to adopt the nation’s strongest methane controls anywhere.
This matters because methane, the main ingredient in natural gas and a common byproduct of oil production, is a damaging greenhouse gas, with more than 80 times the warming power of carbon dioxide over a 20-year time frame.
A big lesson-learned from the months-long, mega-gas leak at Aliso Canyon, and the similarly tragic eight month gas leak in Arvin, CA in 2014, is that oil and gas infrastructure can fail. While leaks the size of Aliso Canyon are rare, it’s an example of the risk we face daily as this infrastructure ages, and a sobering reminder of how important it is to have protections that ensure methane stays in the pipelines—and not in our air.

California’s oil and gas industry emitted approximately 270,000 tons of methane in 2014 – nearly three times the gas released during the Aliso Canyon storage facility disaster. This wasted methane – primarily natural gas – is worth over $50 million, and would have met the heating and cooking needs of about 400,000 homes in the state, had it not been lost to the atmosphere.
Notwithstanding the fact that methane pollution damages the climate and co-pollutants can cause dramatic public health problems, losing natural gas is a wasteful practice. However, as demonstrated during a 2-day joint agency symposium in Sacramento earlier this month, there are businesses that are ready, willing and able to help the state reduce leaks by deploying cutting edge technology, many of which are based in California.
Innovative solutions on display
The symposium featured companies, like United Electric Technologies, Safety Scan, Rebellion and Heath Consultants, that showcased technologies and capabilities being used today to reduce methane emissions across the U.S. in the area of oil and gas production, transmission, and natural gas storage.

Aliso Canyon was a big methane release, especially in Los Angeles, but in the grand scheme of methane released every day by the nation’s oil and gas industry, it was a blip. And recent footage from Texas, coupled with a new study of over 8,000 oil and gas wells gives a glimpse at the kind of leaks that are happening outside of California’s borders – leaks that have huge implications for the state.
The Texas infrared footage shows a cloud of methane leaking from a pump jack in an oil field in Texas’ Permian Basin. While these smaller leaks may not be as egregious as the one at Aliso Canyon, they often go undetected and unaddressed, adding up to a large amount of pollution. And as these leaks happen in Texas – with little plans to stop them – the climate footprint of the gas supply system continues to increase.
So what does this have to do with California? California imports nearly 90 percent of its natural gas from regions across western North America, with a large portion coming from Texas production areas like the Permian and Anadarko basins. To put it another way: when it comes to the climate, what happens in Texas doesn’t stay in Texas. So even while progress is happening to cut oil and gas pollution in the Golden State, there is still a lot of work to be done to make sure imported gas isn’t responsible for significant climate damage before it gets here.

The leak in Southern California Gas Company’s Aliso Canyon Facility released a massive amount of methane – a powerful climate change pollutant. Like other catastrophes, now that the pollution release is stemmed, the focus shifts towards cleanup and mitigation (as well as establishing causation, preventing recurrence, and pursuing legal actions).
Last week California took a major step on the cleanup front with the release of the final Aliso Canyon mitigation plan, a plan to cut pollution equal to about 100,000 metric tons of methane. Its aims to achieve these reductions by focusing on the agriculture and waste sectors, increasing energy efficiency and decreasing use of fossil fuels, and reducing methane “hot spots.”
While the portfolio of strategies laid out within the finalized plan is strong, this is only the beginning of a lengthy process, and one in which pushback from SoCalGas is already palpable. As the critical details of the mitigation plan are put into action, adherence to core principles is necessary to ensure mitigation from the Aliso Canyon disaster is a success story for the climate and people of California.

Methane leaking from pipes before natural gas is delivered to customers can have a large, harmful impact on the climate. This idea was first brought to light in a major scientific paper published in 2012, and supported by numerous papers since. For California, a climate leader, and a state that consumes 10 percent of the nation’s natural gas supply – this leakage epiphany was and continues to be a very big deal.
Last week, after years of science, politics, and policy deliberations, the state took one of its boldest steps yet in the quest to cut methane escaping from its vast network of aging pipes underneath city streets – a move that should result in a new direction for California, and likely for utilities across the nation.
That move, taking the form of a 28-page report and staff recommendations from California Public Utilities Commission (CPUC) as part of the implementation of a 2014 law (SB 1371), proposes to require utilities in California to use specific best practices to find, fix, and prevent leaks from the natural gas distribution system.

After nearly ten months of waiting, California regulators at the state’s Air Resources Board stepped up this month in a big way to reduce emissions of the powerful greenhouse gas methane from the state’s oil and gas industry.
For a state that prides itself on leading the charge to fight climate change, it was odd to see California had been lagging behind others when it came to addressing methane pollution. After all, methane is such a powerful short-term climate forcer that it’s responsible for a quarter of the warming we feel today. Now, by introducing long-awaited draft rules tackling the problem, the golden state has put itself back in the game.
A rule worthy of praise – with still room for improvement
Several provisions in the draft rule represent some of the strongest standards in the nation and have the potential to seriously advance the conversation on methane controls. Among them, the new rule proposes to cover both new and existing sources in oil and gas fields – something that should draw the federal government’s attention as it contemplates whether to include both types of categories in its proposed national rules. The rule also uses better science than prior proposals – evaluating methane’s impact based on its 20-year impact rather than a longer 100-year value. Read More
