Just weeks after this year’s March for ScienceEnvironmental Protection Agency (EPA) administrator Scott Pruitt is taking a shot at science — “secret science,” in his words. Pruitt recently proposed a rule that would limit the kinds of research the agency could draw on in crafting regulations. Reuters described the move as “an apparent concession to big business” which has angled for the restrictions for a long time.

An Environmental Protection Agency (EPA) flag waves in the air at the agency's building in Washington, D.C.

Pruitt’s proposal would mean the EPA wouldn’t be able to use scientific research based on confidential data. That means the agency would only be able to draw on studies that make all their data publicly available for everyone to scrutinize, according to NPR. The administrator said in a statement, “The era of secret science at EPA is coming to an end. The ability to test, authenticate, and reproduce scientific findings is vital for the integrity of rulemaking process. Americans deserve to assess the legitimacy of the science underpinning EPA decisions that may impact their lives.” The EPA’s statement said the proposal is consistent with scientific journals like Nature and Science‘s data access requirements.

But some scientists are worried — the move could place crucial data off limits. NPR quoted Sean Gallagher, the American Association for the Advancement of Science‘s senior government relations officer, as saying, “Our concern with this is they are quite literally limiting the best available science that can be used by the EPA.”

Epidemiological studies are often utilized in the agency’s regulatory decisions, and Gallagher said, “Those studies involve people like you and me, signing confidentiality agreements that the scientists doing the studies won’t reveal my personal health information, like my vital statistics, or my death certificate, if I die during the course of the study. This is the kind of science that the EPA relies on, whether it looks at chemicals or particulates and their mortality or health effects. It involves private data.”

The proposal won’t enter into force yet; Reuters said there will be a 30-day comment period and the proposal would need to be finalized.
