EPA Administrator Scott Pruitt.

Another day, another move to upend the Environmental Protection Agency. EPA Administrator Scott Pruitt made statements this week that suggest he’s on the verge of removing researchers from the agency’s scientific advisory boards if they’ve received EPA grants. Apparently, scientists who receive such grants are incapable of giving unbiased advice.

“What’s most important at the agency is to have scientific advisers that are objective, independent-minded, providing transparent recommendations,” Pruitt told an audience at the conservative Heritage Foundation on Tuesday. “If we have individuals who are on those boards, sometimes receiving money from the agency … that to me causes questions on the independence and the veracity and the transparency of those recommendations that are coming our way.”

In order to “fix” the problem, Pruitt plans to issue a directive sometime next week, although it’s unclear just what that directive might contain. Not surprisingly, environmental groups aren’t happy:

“Pruitt’s purge has a single goal: get rid of scientists who tell us the facts about threats to our environment and health,” Jennifer Sass, a senior scientist for the Natural Resources Defense Council, said in a statement. “There’s a reason he won’t apply the same limits to scientists funded by corporate polluters. Now the only scientists on Pruitt’s good list will be those with funding from polluters supporting Trump’s agenda to make America toxic again.”

And scientists say Pruitt’s plan is deeply flawed, too.
