Energy Dept. Panel Warns of Environmental Toll of Current Gas Drilling Practices

A federal energy panel issued a blunt warning to shale gas drillers and their regulators today, saying they need to step up efforts to protect public health and the environment or risk a backlash that stifles further development.

“Concerted and sustained action is needed to avoid excessive environmental impacts of shale gas production and the consequent risk of public opposition to its continuation and expansion,” said members of the Energy Department’s Shale Gas Subcommittee in a draft report released today.

The seven-member committee, appointed in January by Energy Secretary Steven Chu, provides a way for the Obama administration to weigh in on gas drilling, which is primarily overseen by state regulatory agencies.

In August, the panel issued a lengthy set of recommendations to state and federal agencies and the gas industry for making gas drilling safer.

Today’s report – acknowledging that progress on the panel’s suggestions has been slow – sets out who needs to do what in order to turn recommendations into reality. The panel also stressed the importance of shale gas to the nation’s energy policy, noting that it already makes up 30 percent of domestic gas production.

The report calls on the EPA to revise a proposed rule on air emissions to include limits on methane, a potent greenhouse gas, and criticizes recent moves by the agency that have hindered efforts to get better data from the oil and gas industry, a crucial step toward improving controls.

The report also concludes that joint federal and state efforts to ensure water quality are “not working smoothly” and urges the EPA to move unilaterally to improve oversight as it carries out a study on potential effects of hydraulic fracturing on drinking water.

The panel’s recommendations are not binding, but Amy Mall, a senior policy analyst with the Natural Resources Defense Council, said they carry significant weight.

“We need more experts acknowledging publicly that there are real risks and they can be addressed,” she said. NRDC and other environmental organizations sent a letter to President Obama last week, urging him to issue an executive order directing federal agencies to carry out the panel’s recommendations.

Drilling companies have in the past resisted some policy changes that the panel is recommending, such more stringent federal limits on emissions. Reid Porter, a spokesman for the American Petroleum Institute, an industry group, would not comment on the specific recommendations, but said API members have begun to implement some of the panel’s recommendations, including working with state agencies to strengthen best practices on well design and minimizing water use.

The Energy Department’s advisory board will hold a public meeting on the draft report on Monday before finalizing it.

Correction (11/10): This story has been changed. An earlier version made it seem as if Reid Porter, an API spokesman, said that drillers have opposed some of the energy panel’s recommendations. Porter did not comment on that issue.

Myths in the Public Relations Messages from the Gas Industry

Four myths frequently reported by the gas industry were recently described by Professor Anthony Ingraffea, who is a Faculty Fellow at the Atkinson Center for a Sustainable Future at Cornell University:

Myth 1. Fracking is a 60-year-old, safe, well proven technology – -

Yes, fracking is 60 years old. But using this shorthand obscures the truth that what’s at issue here isn’t really just fracking. It’s the entire process of coaxing gas from shale using high-volume, slickwater fracking with long laterals from clustered, multi-well pads. Used together, they form a new process, having been introduced about five six years ago, the jury is still very much out on its safety.

Myth 2. Fluid migration from faulty wells is rare – – -

Fluid migration is not rare. For example, industry researchers Watson and Bachu, in a Society of Petroleum Engineers paper in 2009, examined 352,000 Canadian wells and found sustained casing pressure and gas migration. They found that about 12 per cent of newer wells leaked, considerably more than older wells. Also, EPA found benzene, methane and chemicals in water-monitoring wells in Pavilion, Wyoming.

Myth 3. The use of clustered, multi-well drilling pads reduces surface impacts – – -

Such pad sites are large and growing, up to 10 acres or more. Newer sites, in Canada, are bigger than 50 acres, and each will leave behind clusters of wellheads and holding tanks for decades. Cluster drilling facilitates and prolongs intense industrialization and leaves a larger, more concentrated, and very long-term footprint, not a smaller and shorter one.

Myth 4. Natural gas is a “clean” fossil fuel – – -

The newest evidence here is discouraging. NASA climate scientist Drew Shindell’s work, published in Science, shows that methane (i.e. natural gas) is 105 times more powerful than carbon dioxide as a global warming contributor over a 20-year time horizon, and 33 times more powerful over a century. Unfortunately, unconventional gas drilling techniques actually leak more methane than conventional ones. Leakage happens routinely during regular drilling, fracking and flowback operations, liquid unloading, processing, and along pipelines and at storage facilities.

Other myths were also mentioned in the article: “There are plenty of other myths swirling around this debate which require analysis: local job-creation versus the reality of imported expertise from Oklahoma and Texas; development of a home-grown resource versus selling gas on the world markets; revitalized, vibrant local economies versus boom-and-bust syndromes of strangled small business investment and profits sent to Norway or China; natural gas as a short-term bridge fuel to renewables, versus an impediment to developing the long-term sustainable energy future.

Officials charge Gas Drilling Company with contaminating the Aquifer

(CBS/AP) The U.S. Environmental Protection Agency issued an emergency order against a Texas gas driller Tuesday, accusing the company of contaminating an aquifer and giving it 48 hours to provide clean drinking water to affected residents and begin taking steps to resolve the problem….

…The EPA inspected the wells with the commission, Armendariz said, and found high levels of explosive methane, as well as other contaminants, including cancer-causing benzene.
