Pipeline Safety Bill Puts New Focus on Aging Gas Infrastructure

By Simi George / Published: April 1, 2016

9496055390_6ce041c81b_oLast month, the U.S. Senate unanimously passed the SAFE PIPES Act, reauthorizing the Pipelines and Hazardous Materials Safety Administration (PHMSA). Tucked inside the bipartisan bill are important new measures intended to advance the ways in which regulators facilitate the repair and replacement of old, increasingly leaky pipeline systems.

The bill also creates a multi-agency task force looking into the health, safety, environmental and economic impacts of the four-month disaster at the 70-year-old Aliso Canyon natural gas storage facility – and what should be done to prevent another one like it.

Aging pipeline systems are a huge challenge. Besides safety concerns, the cost of lost gas is a needless burden on ratepayers. And regulators are also growing increasingly concerned about the climate impact of leaking methane, the main ingredient in natural gas. Read More »

Moving Up: New Accounting Shows Full Scale of Aliso Canyon and U.S. Methane Leaks

By Steven Hamburg / Published: February 25, 2016

rp_AlisoCanyon4-300x209.jpgA paper today in the journal Science, estimating emissions from the massive methane leak at Aliso Canyon, indicates that nearly 100,000 metric tons of methane escaped into the atmosphere over Southern California – more than previous estimates. The new findings come days after the Environmental Protection Agency released draft results of their updated accounting of methane emissions from the nation’s oil and gas supply chain that shows that emissions are up 27% above the agency’s early estimate.

The more we know about methane emissions, the higher they get. The new findings show not just the massive scale of the oil and gas industry’s methane problem, but also how critical it is to get the science right to both understand this source of a potent climate pollutant and reduce it. We know that cutting methane is one of the fastest, most cost effective ways to curb today’s warming, and when combined with critical efforts to reduce carbon dioxide pollution, substantial climate progress can be made.

Coming Soon: Solutions for Finding Methane Leaks Faster

By Aileen Nowlan / Published: February 25, 2016

porter-ranch-aliso-canyon-methane-gas-leak-3-1020x610After more than four months of spewing potent methane pollution, the massive Aliso Canyon gas leak has finally been plugged. But now the state of California and the utility that owns the site, SoCalGas, are left with the responsibility of ensuring a disaster like this doesn’t happen again.

While Aliso Canyon has captured the attention of the nation, it’s important to remember that there are smaller—and far more prevalent—leaks happening throughout the country’s oil and gas supply chain every day. In fact, those emissions add up to more than 7 million metric tons of methane pollution every year.  That equals over $1 billion worth of wasted natural gas at 2015 prices. Read More »

EPA Draft Says Oil & Gas Methane Emissions Are 27 Percent Higher than Earlier Estimates

By David Lyon / Published: February 23, 2016

2014EPAInventory2Methane emissions from the oil and gas industry are significantly higher than previous official estimates, according to draft revisions of the U.S. greenhouse gas emissions inventory released Monday by the Environmental Protection Agency. At 9.3 million metric tons, revised estimates of 2013 emissions are 27% percent higher than the previous tally. Over a 20-year timeframe, those emissions have the same climate impact as over 200 coal-fired power plants. The lost gas is worth $1.4 billion at 2015 prices.

The big jump makes it crystal clear that there can be no more excuses for ignoring this huge challenge – not only controlling methane emissions from future sources, as proposed new EPA rules will do, but also controlling emissions from the tens of thousands of leaking facilities already operating now. Existing systems account for all of today’s emissions, and will generate the lion’s share of pollution for many years to come, yet federal rules so far don’t apply to them. Read More »

California Back In The Saddle On Tackling Oil And Gas Pollution

By Tim O'Connor / Published: February 17, 2016

9194136580_6eb9c79293_oAfter 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 »

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

By Scott Anderson / Published: January 28, 2016

AlisoCanyon4Southern 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.
