“There’s industry with a tremendous vested interest in the policy decisions that might occur later on,” based on the assessments made by ORD. “What the industry does is try to engage in a proxy war over the policy by attacking the science.”
Among the IRIS assessments that stirred the most industry concern were those outlining the dangers of formaldehyde, ethylene oxide, arsenic, and hexavalent chromium. Regulatory actions had begun or were looming on all during the Biden administration.
The Biden administration also launched a lawsuit against a LaPlace, Louisiana, plant that had been the only US manufacturer of neoprene, Denka Performance Elastomer, based in part on the IRIS assessment of one of its air pollutants, chloroprene, as a likely human carcinogen. Denka, a spinoff of DuPont, announced it was ceasing production in May because of the cost of pollution controls.
Public health advocates charge that eliminating the IRIS program, or shifting its functions to other offices in the agency, will rob the EPA of the independent expertise to inform its mission of protection.
“They’ve been trying for years to shut down IRIS,” said Darya Minovi, a senior analyst with the Union of Concerned Scientists and lead author of a new study on Trump administration actions that the group says undermine science. “The reason why is because when IRIS conducts its independent scientific assessments using a great amount of rigor… you get stronger regulations, and that is not in the best interest of the big business polluters and those who have a financial stake in the EPA’s demise.”
The UCS report tallied more than 400 firings, funding cuts, and other attacks on science in the first six months of the Trump administration, resulting in 54 percent fewer grants for research on topics including cancer, infectious disease, and environmental health.
