The New York Times reported today that the controversial PM2.5 Panel (which studies Particulate Matter, 2.5 micrometers in diameter or less,” i.e. small enough to invade even the smallest airways), comprised mostly of EPA grantees, is being disbanded. Their provocative findings –– which alleged that “PM2.5 would kill more than 2,000 per year in southern California due to air pollution,” and which led to the recent passage of a $28 billion increase to taxpayers in southern California –– have been recently published in the N Engl J Med (and described in these GEITP pages) and challenged by many epidemiologists and other scientists who cannot accept a universal Linear No-Threshold (LNT) Model. This model proposes that every environmental agent, even one mollecule, will be toxic to cells, whereas opponents claim that most, if not all, environmental agents (including gamma-irradiation) are safe, or even beneficial, at low concentrations –– although they can be toxic at higher concentrations.
Below this NYT article today is a WSJ article from July, 2o17, describing the problem with the controversial PM.5 Panel.
EPA disbands PM2.5 panel
EPA is disbanding the CASAC PM panel that was accused of being “too in-house” opinionated.
From today’s (Oct 14, 2o18) New York Times:
This was a Wall Street Journal July 17, 2o17 Op-Ed article:
The Trump administration in May began the process of replacing the small army of outside science advisers at the Environmental Protection Agency. In June 2017, 38 additional EPA advisers were notified that their appointments would not be renewed in August. To Mr. Trump’s critics, this is another manifestation of his administration’s “war on science.” Histrionics aside, the administration’s actions are long overdue.
The most prominent of the EPA’s myriad boards of outside advisers are the Science Advisory Board and the Clean Air Scientific Advisory Committee, or CASAC. Mostly made up of university professors, these boards also frequently draw members from consulting firms and activist groups. Only rarely do members have backgrounds in industry. All EPA boards are governed by the Federal Advisory Committee Act, which requires that they be balanced and unbiased. While the EPA is required by law to convene the SAB and CASAC, the agency is not bound by law to heed their advice.
The EPA’s Obama -era “war on coal” rules and its standards for ground-level ozone—possibly the most expensive EPA rule ever issued—depend on the same scientifically unsupported notion that the fine particles of soot emitted by smokestacks and tailpipes are lethal. The EPA claims that such particles kill hundreds of thousands of Americans annually.
The EPA first considered regulating fine particles in the mid-1990s. But when the agency ran its claims past CASAC in 1996, the board concluded that the scientific evidence did not support the agency’s regulatory conclusion. Ignoring the panel’s advice, the EPA’s leadership chose to regulate fine particles anyway, and resolved to figure out a way to avoid future troublesome opposition from CASAC.
In 1996 two-thirds of the CASAC panel had no financial connection to the EPA. By the mid-2000s, the agency had entirely flipped the composition of the advisory board so two-thirds of its members were agency grantees. Lo and behold, CASAC suddenly agreed with the EPA’s leadership that fine particulates in outdoor air kill. During the Obama years, the EPA packed the CASAC panel. Twenty-four of its 26 members are now agency grantees, with some listed as principal investigators on EPA research grants worth more than $220 million.
Although the scientific case against particulate matter hasn’t improved since the 1990s, the EPA has tightened its grip on CASAC. In effect, EPA-funded researchers are empowered to review and approve their own work in order to rubber-stamp the EPA’s regulatory agenda. This is all done under the guise of “independence.”
Another “independent” CASAC committee conducted the most recent review of the Obama EPA’s ground-level ozone standards. Of that panel’s 20 members, 70% were EPA grantees who’d hauled in more than $192 million from the agency over the years. These EPA panels make decisions by consensus, which has lately been easy enough to achieve considering they are usually chaired by an EPA grantee.
Would-be reformers have so far had no luck changing the culture at these EPA advisory committees. In 2016 the Energy and Environment Legal Institute, where I am a senior fellow, sued the agency. We alleged that the CASAC fine-particulate subcommittee was biased—a clear violation of the Federal Advisory Committee Act. We found a plaintiff who had been refused CASAC membership because of his beliefs about fine particles. Unfortunately, that individual was not willing to take a hostile public stand against the EPA for fear of professional retribution. We ultimately withdrew the suit.
The EPA’s opaque selection process for membership on its advisory boards has opened the agency to charges of bias. In 2016 Michael Honeycutt, chief toxicologist of the Texas Commission on Environmental Quality, was recommended in 60 of the 83 nominations to the EPA for CASAC membership. The EPA instead selected Donna Kenski of the Lake Michigan Air Directors Consortium. Ms. Kenski received only one of the 83 recommendations. While no one objected to Mr. Honeycutt’s nomination, Sen. James Inhofe (R., Okla.) lodged an objection to Ms. Kenski’s nomination, claiming she had exhibited partisanship during an earlier term on the committee.
Congress has also tried to reform the EPA’s science advisory process. During the three most recent Congresses, the House has passed bills to provide explicit conflict-of-interest rules for EPA science advisers, including bans on receiving EPA grants for three years before and after service on an advisory panel. The bills went nowhere in the Senate, where the threat of a Democrat-led filibuster loomed. Had they passed, President Obama surely would have vetoed them.
President Trump and his EPA administrator have ample statutory authority to rectify the problem. As Oklahoma’s attorney general, Scott Pruitt spent years familiarizing himself with the EPA’s unlawful ways. He is in the process of reaffirming the independence of the agency’s science advisory committees. This won’t mean that committee members can’t have a point of view. But a committee as a whole must be balanced and unbiased. Mr. Pruitt’s goal is the one intended by Congress—peer review, not pal review.
