Why has the U.S. Environmental Protection Agency (EPA) failed to take adequate action against disastrous, climate-warming methane emissions from the fracking industry?

An environmental watchdog alleges that the answer may be a years-long, systematic cover-up of the true data surrounding these toxic emissions. That cover-up, the group says, was at the hands of at least one EPA researcher who accepted payments from the oil and gas industry.

In an incendiary federal complaint filed on Wednesday with the EPA's Inspector General, the 28-year-old North Carolina-based group NC WARN wrote that "there has been a persistent and deliberate cover-up that has prevented the agency from requiring the natural gas industry to make widespread, urgently needed and achievable reductions in methane venting and leakage across the nation's expanding natural gas infrastructure."

"Studies relied upon by EPA to develop policy and regulations were scientifically invalid," the organization charged.

Specifically, wrote NC WARN in a press statement, "Dr. David Allen, then-head of EPA's Science Advisory Board, has led an ongoing, three-year effort to cover up underreporting of the primary device, the Bacharach Hi-Flow Sampler and a second device used to measure gas releases from equipment across the natural gas industry. Allen is also on the faculty of the University of Texas at Austin, where he has been funded by the oil and gas industries for years."

"The EPA's failure to order feasible reductions of methane leaks and venting has robbed humanity of crucial years to slow the climate crisis," said Jim Warren, director of NC WARN. "The cover-up by Allen's team has allowed the industry to dig in for years of delay in cutting emissions—at the worst possible time."

The cover-up was discovered by NC WARN, the group wrote in its complaint, when it became aware that the very inventor of the Bacharach Hi-Flow Sampler, an engineer named Touché Howard, had been attempting to blow the whistle for years on the crucial instrument's malfunctioning. The critical failure causes the instrument to under-report methane emissions "up to 100-fold," the organization wrote.

Studies have shown the EPA underestimating methane leaks from fracked gas production for years and Howard's own research found that the agency has been "hugely underestimating" methane emissions specifically as a result of the faulty instrument, asCommon Dreams reported.

"In the extreme, that kind of failure could lead to catastrophic explosions," Howard told the Los Angeles Times.

The complaint describes Howard's repeated attempts to warn the EPA and Allen about the instrument and the silence he received in response.

"It appears that the goal of the [University of Texas] team was not to critically examine the problems but to convince [Environmental Defense Fund, who co-authored the study] and its production committee members that no problems existed," NC WARN added.

"We believe Mr. Howard was specifically prevented from providing input because the [University of Texas] team knew that he would be able to show that their counterarguments were faulty and the resulting studies scientifically invalid," the group concluded.

Howard's concerns and the specific mechanical problems of the measurement instrument he has repeatedly pointed out have to this date never been addressed, "resulting in the failure of the EPA to accurately report methane emissions for more than two years, much less require reductions," the complaint noted. "Meanwhile, the faulty data and measuring equipment are still being used extensively throughout the natural gas industry worldwide."

Indeed, a graphic included in the complaint demonstrates that the malfunctioning Bacharach Hi-Flow Sampler is relied upon to measure methane emissions at nearly every point in the fracked gas production process:
