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

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.

A Handy Checklist for Regulators on Well Integrity

20141118_132328After 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 »

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

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.
