WASHINGTON — The Trump administration is preparing to significantly limit the scientific and medical research that the government can use to determine public health regulations, overriding protests from scientists and physicians who say the new rule would undermine the scientific underpinnings of government policy making.
A new draft of the Environmental Protection Agency proposal, titled Strengthening Transparency in Regulatory Science, would require that scientists disclose all of their raw data, including confidential medical records, before the agency could consider an academic study’s conclusions. EPA officials called the plan a step toward transparency and said the disclosure of raw data would allow conclusions to be verified independently.
“We are committed to the highest quality science,” Andrew Wheeler, the EPA administrator, told a congressional committee in September. “Good science is science that can be replicated and independently validated, science that can hold up to scrutiny.”
The measure would make it more difficult to enact new clean air and water rules because many studies detailing the links between pollution and disease rely on personal health information gathered under confidentiality agreements. And, unlike a version of the proposal that surfaced in early 2018, this one could apply retroactively to public health regulations already in place.
“This means the EPA can justify rolling back rules or failing to update rules based on the best information to protect public health and the environment, which means more dirty air and more premature deaths,” said Paul Billings, senior vice president for advocacy at the American Lung Association.
Public health experts warned studies that have been used for decades — to show, for example, that mercury from power plants impairs brain development, or that lead in paint dust is tied to behavioral disorders in children — might be inadmissible when existing regulations come up for renewal.
For instance, a groundbreaking 1993 Harvard University project that definitively linked polluted air to premature deaths, currently the foundation of the nation’s air-quality laws, could become inadmissible. When gathering data for their research, known as the Six Cities study, scientists signed confidentiality agreements to track the private medical and occupational histories of more than 22,000 people in six cities. They combined that personal data with home air-quality data to study the link between chronic exposure to air pollution and mortality.
But the fossil fuel industry and some Republican lawmakers have long criticized the analysis and a similar study by the American Cancer Society, saying the underlying data sets of both were never made public, preventing independent analysis of the conclusions.
The change is part of a broader administration effort to weaken the scientific underpinnings of policy making. Senior administration officials have tried to water down the testimony of government scientists, publicly chastised scientists who have dissented from President Trump’s positions and blocked government researchers from traveling to conferences to present their work.
On Wednesday, the House Committee on Science, Space and Technology will hold a hearing on the EPA’s efforts. A top pulmonary specialist and a representative of the country’s largest nonprofit funder of research on Parkinson’s disease, the Michael J. Fox Foundation, are expected to testify that the EPA’s proposed rule would eliminate the use of valuable research showing the dangers of pollution to human health.
The National Association of Pediatric Nurse Practitioners said it was “deeply concerned” that the rule would lead to the exclusion of studies, “ultimately resulting in weaker environmental and health protections and greater risks to children’s health.” The National Center for Science Education said ruling out studies that do not use open data “would send a deeply misleading message, ignoring the thoughtful processes that scientists use to ensure that all relevant evidence is considered.”
