How community air monitoring projects provide a data-driven model for the future

Nicoyia Hurt, EDF Oil and Gas Health Policy Intern, contributed to this post

Downtown Los Angeles with misty morning smog.

This month marks the one year anniversary since the residents in Imperial County California did something pretty amazing.

After experiencing some of the highest asthma hospitalization rates in the state, the community got together to launch the IVAN air monitoring project– a community website that provides real time air quality data collected from 40 different pollution monitors across the county.

Frances Nicklen said the air monitors make a huge difference to her community.

"The placement of these 40 air monitors throughout the Imperial Valley will be very beneficial so that the people can make educated decisions to protect their health and that of their families," she told the Comite Civico Del Valle. “We only have one valley, and we have to live here, and we need to make it a better place for all of our residents.” Read More »

Investor sees methane management as self-help for oil and gas companies

Q&A with Tim Goodman, Hermes Investment Management

When burned, natural gas produces half the carbon as coal, so it is often touted as a “bridge” fuel to a cleaner energy future. But the carbon advantage of natural gas may be lost if too much of it escapes across its value chain.

Natural gas is mostly methane, which, unburned, is a highly potent greenhouse gas accounting for roughly a quarter of today’s global warming. Worldwide, oil and gas companies leak and vent an estimated $30 billion of methane each year into the atmosphere.

EDF’s Sean Wright sat down with Tim Goodman, Director of Engagement at London-based Hermes Investment Management. Goodman, who views methane management as practical self-help for the industry to pursue, engages with oil and gas companies on strategies to manage their methane emissions. This is the first of a two-part conversation with Hermes, a global investment firm, whose stewardship service Hermes EOS, advises $330.4 billion in assets.  Read More »

Busy in the Beehive: Utah joins growing list of states tackling oil and gas pollution

Ozone pollution — also known as smog — is a growing problem in Utah, both in the state’s urban areas and in largely rural regions where oil and gas development has been directly tied to unhealthy air.

That’s why new draft rules for oil and gas emissions released yesterday are a breath of fresh air for the Beehive State.

These new standards are designed to reduce the amount of smog-forming volatile organic compound (VOC) pollution emitted from both new and existing oil and gas sites across Utah. If strengthened and finalized as soon as possible, these rules will help limit Utah’s smog problem and protect Utah families from asthma attacks, respiratory problems and other health issues.

Natural gas, meet Silicon Valley. The challenge for mobile methane monitoring is now underway

 Ben Ratner and Ramon Alvarez, Ph.D. 

Three years ago, Environmental Defense Fund (EDF) united with oil and gas industry leaders including Shell and Statoil to launch the Methane Detectors Challenge – a collaborative effort to catalyze the development and deployment of stationary, continuous methane monitors. With industry pilot projects now cropping up from Texas to Alberta, continuous methane monitoring on natural gas sites is on a pathway to become one of the core tools in the monitoring toolkit.

And that’s a good thing – 24/7 monitoring is the gold standard for emissions control, opening a new frontier in site-level insight. It will enable real time identification and repair of natural gas waste that pollutes the atmosphere, and the industry’s own reputation.

Now, another exciting area of innovation is emerging, as entrepreneurs, technologists, and academics pursue mobile approaches to monitor leaks. Whether by plane, helicopter, drone or truck, mobile monitoring offers the promise of surveying highly dispersed industrial facilities – including smaller and older ones – quickly and effectively. With an estimated one million well pads in the United States alone, the speed and coverage of monitoring matter. Read More »

California’s new methane leakage requirements for gas utilities are already delivering benefits

EDF Schneider fellow Scott Roycroft co-authored this post

California’s gas utilities have had their share of problems in recent years – so improvements in environmental impacts, operations, and safety are important to track.

In 2014, the California legislature passed a law to require utility companies to publicly disclose data on gas leaks and emissions while working to actually cut those emissions.  Now, three years later, utility reporting has been standardized, an emissions trend has emerged, and the results are significant.

New study reveals gaps in the methods used to assess chemicals in oilfield wastewater

A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.

Oilfield wastewater is extremely salty and can contain multiple combinations of many potentially harmful chemicals (approximately 1600 on a national basis). However, most standard or approved analytical methods available to regulators were designed to work with fresh water. Because oil and gas wastewater is so salty—sometimes 10 times saltier than seawater or more—chemists often have to dilute wastewater samples to manage the high salt content.

This means they may also be diluting chemicals of concern to concentrations too low to detect, even though they may be present at risky levels. For example, benzene is a chemical associated with petroleum hydrocarbons and a known carcinogen. It also has a drinking water standard of 5 parts per billion – that’s 5 cents in 10 million dollars. It really doesn’t take much dilution of a sample to lose that level of precision. Read More »
