'A National Outrage': Days After Monsanto Ruling, Trump EPA Approves More Forever Chemical Pesticides

Ripping "Trump's reckless push to ignore science and embrace these extremely harmful, long-lasting pesticides," one critic said his legacy will be the millions "his shortsighted policies will sicken and prematurely kill."

The US Environmental Protection Agency on Tuesday continued its betrayal of President Donald Trump's campaign promise to "Make America Healthy Again," approving the use of multiple "forever chemical" pesticides on crops despite public health concerns.

Per- and polyfluoroalkyl substances (PFAS) are called forever chemicals because they don't naturally break down—instead accumulating in human and animal bodies as well as the environment. They have been used in everything from fabrics for clothing and furniture to firefighting foam to nonstick cookware, and are tied to various health problems, including increased risk of some cancers.

The Trump EPA on Tuesday finalized its approval of using two PFAS pesticides, diflufenican and epyrifenacil, on corn and soybeans, the two most widely grown crops in the United States.

The agency also expanded its allowances for another previously approved forever chemical pesticide, bifenthrin, and greenlighted the first food use of chlormequat, a non-PFAS pesticide tied to reproductive issues.

"While the Biden administration had approved one PFAS pesticide in the prior four years, this is the third and fourth approval of a PFAS pesticide under Trump in just his second year in office," the Center for Biological Diversity (CBD) noted in a Tuesday statement. "The previous two PFAS pesticide approvals were cyclobutrifluram and isocycloseram."

As the center detailed:

The EPA has stated in press materials that these new fluorinated pesticides are not PFAS. That assertion is based on the fact that they do not meet the chemicals office's unilateral regulatory PFAS definition. But the new pesticides do meet the much more widely accepted PFAS definition that was developed transparently by dozens of scientists around the world. That definition has subsequently been endorsed by more than 150 leading PFAS researchers, is used by nearly every US state for regulating PFAS, and specifically was written into past versions of the National Defense Authorization Act.

Using the scientific definition of a PFAS that is widely accepted in this country and around the world, these pesticides are PFAS.

The EPA had even initially acknowledged that these pesticides met the more broadly accepted PFAS definition on its fluorinated pesticides webpage. Yet three weeks after creating the webpage, it removed any mention of the conflicting definition, instead portraying the agency’s unilateral definition as the only PFAS definition.

Under the Freedom of Information Act, CBD obtained documents showing that those website revisions were overseen by EPA Office of Chemical Safety and Pollution Prevention's assistant administrator, Douglas Troutman, and Kyle Kunkler—a former American Soybean Association (ASA) lobbyist controversially installed as the office's deputy assistant administrator for pesticides—and reviewed by agency Administrator Lee Zeldin.

While ASA president and Ohio soybean farmer Scott Metzger welcomed the Tuesday approvals, saying that "we appreciate EPA Administrator Lee Zeldin and the agency" for advancing the registrations, Nathan Donley, CBD's environmental health science director, was deeply critical and tied the developments to the Trump administration's other actions serving the pesticide industry.

"It's a national outrage that Trump's EPA is expanding use of dangerous, cancer-linked PFAS pesticides just days after the Supreme Court limited the American people's right to sue pesticide companies," said Donley, referring to last week's ruling in favor of Monsanto and against thousands of people who argue that its glyphosate-based weedkiller Roundup caused their cancer.

In addition to the Trump administration backing Bayer—which bought Monsanto in 2018—in the case before the high court, the president in February issued an executive order mandating the production of glyphosate. Since returning to office last year, Trump has also faced criticism for EPA approvals of other pesticides, from atrazine to dicamba, and for his administration's MAHA report that echoes industry talking points.

Donley declared Tuesday that "Trump's reckless push to ignore science and embrace these extremely harmful, long-lasting pesticides ensures his legacy won't be the many monuments he's built to himself, but the many millions of people his shortsighted policies will sicken and prematurely kill."
