Rigorous, independent research and analysis should undergird everything the government does. Nowhere is that more true than at the Environmental Protection Agency, which crafts and enforces a wide range of regulations aimed at limiting damage to the environment — and to people — from pollutants. Democratic administrations tend to use data to justify more aggressive regulation, while Republican administrations tend to prefer a lighter touch. But the current administration is following a third path, seemingly bent on converting the EPA into a science-be-damned rubber stamp for industry. And if director Scott Pruitt is successful, we will be living in a much more dangerous environment.

When his name first surfaced as President Trump’s pick to run the agency, critics complained that the president was putting a fox in charge of the henhouse. Pruitt has done nothing to dissuade the country that his critics were wrong. In his most recent move, he has decreed that academics and other scientists who hold research grants through the EPA cannot serve on long-standing panels that advise the EPA on the science upon which it bases its regulations.

These committees aren’t merely window-dressing; rather, their work carries considerable weight at the agency. But Pruitt’s new ban, which he said is necessary to avoid conflicts of interest, would boot many of the academic researchers. It’s a stretch to argue that because the scientists conduct some of their research under EPA grants — won through competitive bids — that they can’t offer independent advice.

Pruitt notably has issued no similar ban on people who work in industries facing regulation, where the conflict of interest is clear. Terry F. Yosie, who directed the Scientific Advisory Board in the Reagan administration (itself no friend of regulation), told The Washington Post that Pruitt’s move represents “a major purge of independent scientists and a decision to sideline the SAB from major EPA decision-making in the future.”

The new policy is in keeping with some of Pruitt’s other troubling moves at the EPA. Critics complain that he gives more time to industry voices than to his in-house experts or environmentalists and operates under a cloak of secrecy (he’s installing a soundproof booth in his office and generally bars note-taking at meetings).

All of this is being done to undercut an agency that Pruitt spent years suing, and then was appointed to run. Pruitt signed off on a proposal to cut his own budget by nearly a third, and has aggressively worked to undo or undermine more than 50 rules and regulations promulgated primarily by the Obama administration. By replacing academic researchers on his advisory panels with people tied to industry or those who share his disdain for science, he makes a mockery of the idea that science ought to be the result of independent inquiry, not ideology.

Pruitt is under investigation over his frequent trips home to Oklahoma using tax dollars and his occasional use of costly private planes and military aircraft. Whether that will affect his future at the EPA is unknown. But what is clear is that he has been a disaster for the agency and the environment. And this new move to clear the advisory panels of some of the nation’s most respected researchers in their fields is unconscionable.
