Widely-Used Tool Can Lowball Methane Pollution Rates, Scientists Report, With Huge Implications for Climate Policy

An EPA-approved methane sampler widely used to measure gas leaks from oil and gas operations nationwide can dramatically under-report how much methane is leaking into the atmosphere, a team of researchers reported in a peer-reviewed paper published in March.

The researchers, one of whom first designed the underlying technology used by the sampler, warn that results from improperly calibrated machines could severely understate the amount of methane leaking from the country’s oil and gas wells, pipelines, and other infrastructure.

“It could be a big deal,” study co-author Amy Townsend-Small, a geology professor at the University of Cincinnati, told Inside Climate News, adding that it’s not yet clear how often the machine returned bad results, in part because figuring out whether there’s an error would have required using a different kind of device to independently test gas concentrations at the time levels were originally recorded.

As Researchers Tie Fracking and Radon, Pennsylvania Moves to Keep Drilling Radioactivity Data Under Wraps

Last week, research into the connection between fracking and radon, an odorless, colorless, radioactive gas, drew international attention, making headlines in English, German and Italian.

The study, published in the scientific journal Environmental Health Perspectives, found that buildings in Pennsylvania counties where fracking is most common had significantly higher radon readings than the levels found in counties with little shale gas drilling — a difference that emerged around 2004, when the shale rush arrived.

The potential link between fracking and radon in people's homes was surprising, the researchers, based at the Johns Hopkins Bloomberg School of Public Health, said.

“We found things that actually didn’t give us the reassurance that we thought it would when we started it,” Brian S. Schwartz, MD, a professor in the Department of Environmental Health Sciences at Johns Hopkins told the Baltimore Sun.

In a little-noticed move just one day after the Johns Hopkins report was released, a Pennsylvania court allowed the state's environmental regulators to keep the public from reviewing data from radioactivity testing at oil and gas drilling sites.

New Federal Fracking Rules Rely on FracFocus Even as EPA Research Highlights Site's Flaws

It's a classic case of the government's left hand not knowing what the right hand is doing. Days after the Bureau of Land Management issued new federal rules for fracking on federal land, relying heavily on an industry-run site called FracFocus, the Environmental Protection Agency issued a study mainly noteworthy for the shortcomings of the site that it revealed.

More than 70 percent of the chemical disclosure statements that drillers posted on FracFocus between January 2011 and February 2013 were missing key information because drillers labeled that data “confidential business information,” the EPA reported.

On average, drillers reported using a mix of 14 different chemicals at each well site. At sites where information was withheld, an average of five chemicals were not named.

In fact, FracFocus allowed drillers to conceal the identity of more than one out of every ten chemicals whose use was “disclosed” on the site, EPA researchers found.

This made it impossible for EPA's researchers, who received over 39,000 disclosure statements from FracFocus in March 2013 and published their study two years later, to definitively say what chemicals drillers used most often, how much of each chemical was injected underground, or even to simply create a list of all the chemicals used at the wells.

"Frack Pack" Bills Introduced, Aim to Rein in Environmental Damage From Fracking Industry

On Thursday, Congressional Democrats introduced a set of four bills aimed at countering the environmental harms from hydraulic fracturing, or fracking, and the continuing shale gas rush.

Four Representatives — Reps. Diana DeGette and Jared Polis of Colorado, Matt Cartwright of Pennsylvania, and Jan Schakowsky of Illinois — and one Senator, Pennsylvania's Bob Casey, together announced the proposed legislation, dubbing the bills the “Frack Pack” and saying they were designed to roll-back loopholes in existing federal laws.

EPA's National Study into Fracking Narrowed as Key Goals Fall by Wayside Due to Industry Pressure

In 2010, when Congress tasked the EPA with launching a national study of the risks posed by hydraulic fracturing, environmentalists were cautiously optimistic.

“At least the EPA is paying attention,” Don Young, founder of Fort Worth Citizens Against Neighborhood Drilling Operations told the Christian Science Monitor in 2010. 

And for a while, there seemed to be strong signs that the EPA planned to conduct a rigorous investigation. At the outset, the agency's plans included investigations into public health impacts, air pollution, well failures, run-off, and a range of other harms associated with the shale drilling rush.

And into 2011, EPA withstood intense pressure from the shale gas industry and its supporters in Congress to sharply narrow the scope of their research, and in particular to focus exclusively on one part of the process, the actual frac job, rather than to look at the full range of impacts from shale oil and gas extraction.

But at the same time, the goals of the national study were drastically narrowed. Plans, for example, to model the hazards potentially posed by dumping radioactive fracking wastewater at sewage treatment plants — essentially flushing it down the drain and allowing it to enter rivers only partially treated, as was common in Pennsylvania at the time — were slashed from the study.

That industry pressure has continued in the years since, and over time, EPA has indeed dramatically lowered its ambitions and limited the scope of its research, leaving only a small fraction of the original study standing, based on a review by DeSmog of internal EPA documents and emails.

Internal Documents Reveal Extensive Industry Influence Over EPA's National Fracking Study

In 2010, the Environmental Protection Agency (EPA) launched an ambitious and highly consequential study of the risks that hydraulic fracturing, or fracking, poses to American drinking water supplies.

This is about using the best possible science to do what the American people expect the EPA to do – ensure that the health of their communities and families are protected,” Paul Anastas, Assistant Administrator for the agency's Office of Research and Development, said in 2011.

But the EPA's study has been largely shaped and re-shaped by the very industry it is supposed to investigate, as energy company officials were allowed to edit planning documents, insisted on vetting agency contractors, and demanded to review federal scientist's field notes, photographs and laboratory results prior to publication, according to a review by DeSmog of over 3,000 pages of previously undisclosed emails, confidential draft study plans and other internal documents obtained through open records requests.

Company officials imposed demands so infeasible that the EPA ultimately dropped a key goal of the research, their plans to measure pollution levels before and after fracking at two new well sites, the documents show.

All told, the documents raise serious questions about the study's credibility and they highlight a certain coziness between the EPA and Chesapeake Energy, one of the most aggressive oil and gas companies in the shale gas rush.

“[Y]ou guys are part of the team here,” one EPA representative wrote to Chesapeake Energy as they together edited study planning documents in October 2013, “please write things in as you see fit”.

Chesapeake took them up on the offer.
