California Has Solid Data on Methane Leaks, Now They Need To Be Fixed

By EDF Blogs / Published: August 23, 2016

Until recently Californians were in the dark when it came to the state’s natural gas distribution system and its pollution. But all that is changing now; for the first time ever, consistent data on the annual methane emissions from gas utilities is available for all to see. And what does this data show? California has room to reduce leaks and tighten the integrity of its gas delivery system.

A move toward better transparency

California’s recent step to boost disclosure of the amount of emissions leaked and number of repairs made to gas pipelines and other equipment is the product of Senate Bill 1371 (Leno) passed in 2014, and subsequent regulations from the California Public Utilities Commission (CPUC). SB 1371 took this approach because methane, the main component of natural gas, is a powerful climate pollutant that puts our environment and communities at risk with a leak-prone system across the natural gas transmission, distribution and storage sectors.

New EPA Guidelines: An Opportunity to Reduce Smog, Protect Public Health

By EDF Blogs / Published: August 23, 2016

With families across the country starting back to school this week, the official summer season may be gone, but the ozone season is still in full swing.

Ozone, more commonly known as “smog” is a harmful air pollutant that results in respiratory ailments like asthma and can even lead to premature death. For too many Americans, ozone pollution makes the activities that we enjoy doing outdoors in the summer difficult or even impossible. And in recent years, ozone—once a summertime phenomenon impacting mostly larger cities—now affects rural parts of the country and can persist throughout the year. In fact, rural Wyoming and Utah have experienced elevated ozone levels in the winter on par with some of the larger cities in the country. Read More »

10 Reasons Why We Love Community Solar

By Jorge Madrid / Published: August 2, 2016

Carlos Mandeville co-authored this post.

This year is set to be another record-breaker for solar power: the industry is on pace to nearly double in size by the end of 2016, and there are now more than one million solar installations in the U.S. that generated more new electricity in the first quarter of the year than coal, natural gas, and nuclear combined. This is good news, in part because 2016 is also on track to be the hottest year in recorded history – awash in scorching hot solar rays we can tap for clean, renewable energy.

Unfortunately, solar power is still inaccessible to vast, unreached markets and segments of the U.S. population. The National Renewable Energy Laboratory says only 22 to 27 percent of residential rooftops are capable of hosting a solar system because of structural challenges, tree shading, or “ownership issues” – mainly households who rent, and cannot install solar panels on roofs they don’t own. Likewise, U.S. households who earn less than $40,000 per year (40 percent of the U.S. population) account for less than five percent of all solar installations.

But the solar game is changing. New models are emerging to complement and fill gaps in the market.

Only the Gold Standard for the Golden State When Targeting Methane Pollution

By Tim O'Connor / Published: July 21, 2016

Golden_Gate_Bridge_bei_Nacht 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.

Making Gas Pipelines Safer for Communities and the Climate

By Hillary Hull / Published: July 14, 2016

In response to the deadly natural gas explosion in San Bruno, California, the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) is proposing new regulations to make pipelines safer. The regulations will go a long way toward safeguarding communities from the risks of natural gas explosions, but, if they’re done right, they could also protect the climate.

Natural gas is mostly methane – a potent climate pollutant, and reducing the amount of gas that leaks from pipelines also reduces emissions of methane. But there are aspects of the proposal that could result in an increase in methane emissions if proper action isn’t taken. The proposed safety measures require operators to conduct more testing to ensure that pipelines can handle high pressures of gas. Before this testing begins pipeline operators have to empty the pipes by blowing gas down the pipeline. Opponents to the rule say this would create a significant increase in methane emissions, but fortunately a recent study from a leading environmental consulting firm concluded otherwise. Read More »

3 Things to Know About Gas Pipeline Regulations

By Holly Pearen / Published: July 6, 2016

A ruptured natural gas pipeline in the quiet community of San Bruno, California ignited on the evening of September 9, 2010. The resulting fire destroyed 38 homes, killed eight people, and injured many others. It was one of the biggest pipeline explosions in recent history, and it very likely could have been prevented.

Now, almost six years later, the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) is proposing new regulations to prevent serious incidents, like what happened in San Bruno, from happening again. Read More »
