Aliso Canyon Disaster One Year Later: Some Progress, But More Action Needed

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

When the gusher of methane pouring out of the Aliso Canyon natural gas storage field was discovered last October 23, it almost instantly transformed the sleepy Los Angeles suburb of Porter Ranch into the site of one of the biggest environmental disasters in recent history. It would ultimately take four months to stop the massive leak. According to a new report released today, it pumped nearly 100,000 tons of methane into the atmosphere.

Now, a year later, the question: What’s been done to fix the problem, and to prevent future blowouts – either at Aliso Canyon, or the 400 similar facilities in more than 30 states? The answer is, while there’s been some progress, it’s not nearly enough.

New EPA Guidelines Will Help Oil And Gas Communities Breathe Easier

By Felice Stadler / Published: October 20, 2016

While air quality as a whole has been improving across the United States over the past few decades, many areas that are ground zero for the nation’s expanding oil and gas industry have shown an increase in dangerous pollutants. In fact, states with substantial drilling activities saw worsening air quality recently, according to the American Lung Association’s last State of the Air report.

That’s because the oil and gas industry is the largest industrial source of volatile organic compounds (VOCs), which mix with NO_X and sunlight to form ground-level ozone, also known as smog. Additionally, existing oil and gas sources do not face comprehensive nationwide limits for this type of pollution.

This smog has tangible effects, though. In late September, the Clean Air Task Force released a report detailing that the amount of smog forming emissions from the oil and gas sector could lead to as many as 750,000 asthma attacks. The report, called “Gasping for Breath,” similarly documents that these emissions could lead to more than 500,000 days of school missed and 2,000 asthma-related emergency room visits. Accompanying the report is an interactive map, developed by Earthworks, which displays data about the location of active oil and gas wells, and areas of threats to public health.

What would it mean for Los Angeles to go 100% renewable?

By Irene Burga / Published: October 20, 2016

10182500174_6070b2f074_k The Los Angeles City Council recently passed a unanimous resolution requiring Los Angeles Department of Water and Power – the largest municipally-owned utility in the country — to study how the city can achieve a 100% clean energy future. With help from research partners, including academic institutions, the U.S. Department of Energy, and environmental and consumer groups, the study has the potential to become a foundational roadmap for running the utility on only clean and renewable energy.

California currently has a goal to reduce greenhouse gas emissions 40% below 1990 levels by 2030, with half of the state’s energy supply powered by renewable electricity by 2030. To achieve these targets, it is imperative for the state to look seriously at how to get off of fossil fuel dependency for our energy needs. Utilities and cities can be the key to reaching those climate goals. Read More »

Latest EPA Greenhouse Emission Numbers Demonstrate Success Of Methane Standards

By David Lyon / Published: October 7, 2016

Click image to expand

This week sees the release of new figures from the U.S. Greenhouse Gas Emissions Reporting Program (GHGRP), which includes self-reported, large facility-level emissions data for 2015.

The good news is that methane pollution from the oil and gas industry is down slightly, thanks to a combination of stronger safeguards starting to take effect, along with a decline in new drilling projects due to an overall market cooling.

Operators report that methane pollution from onshore oil and gas production is down about 3.8% in 2015 from 2014. However, overall greenhouse gas emissions from all reporting segments in the oil and gas sector are only down 1.6%.

Sensible methane standards are starting to work

Some in industry will undoubtedly point to the new numbers as evidence that new emission rules are unnecessary. In fact, the figures show that sensible safeguards are responsible for much of the progress. Read More »

A Handy Checklist for Regulators on Well Integrity

By Adam Peltz / Published: September 12, 2016

20141118_132328 After several years of collaboration among regulatory experts from across the country, the Groundwater Protection Council (GWPC), recently published a set of 136 “Regulatory Elements” intended to provide regulators with ideas to consider when improving oversight of the permitting, construction, operation and plugging of oil and gas wells.

This may sound dry, but regulations addressing these elements are what keep oil and gas wells from blowing up during drilling or later leaking methane, oil, saltwater, hydraulic fracturing fluid, and other contaminants into air or groundwater.

With over 15 million Americans living within a mile of a well, strong rules on well integrity covering the wide variety of topics addressed in these elements make a huge difference to human health and the environment. Read More »

Smart Policies to Stop Disastrous Natural Gas Leaks

By Adam Peltz / Published: August 29, 2016

Infrared footage reveals massive methane emissions from a gas storage facility in California’s Aliso Canyon

Last fall, a massive leak from a natural gas storage facility in California’s Aliso Canyon released nearly 100,000 tons of methane pollution into the atmosphere — the largest uncombusted release of this potent greenhouse gas in U.S. history, and seen by many as the industry’s worst environmental disaster since the BP oil spill.

Facilities like Aliso Canyon inject gas pumped in from elsewhere and withdraw it when needed for electric production or heating. Aliso Canyon is the largest field of its kind west of the Mississippi River. There are around 400 such facilities across the U.S., about 14 in California. Until recently, regulatory oversight of these facilities has been uneven at best.

The exact cause of the Aliso Canyon incident is still being investigated, but all signs point to a problem in the aging, corroded casing of one of over a hundred individual wells at the sprawling site. Neither the utility’s maintenance programs nor the state’s lax enforcement of 1980s-era policies were sufficient to prevent this disaster. But now that’s about to change. Read More »
