It also would likely have a chilling effect on the agency's ability to conduct research on the environmental issues it is charged with regulating.
Ericksen's comments come just days after Trump's team ordered agencies to limit their external communications to the public. Employees at the EPA, the Department of Agriculture and the Interior Department, among others, have been instructed not to post on social media accounts. At the EPA, the staff was told not to speak to the news media.
Ericksen said it's not abnormal for administrations to limit outward communication during their transition while they work toward getting different branches on point. Trump's nominee for EPA administrator, Oklahoma Attorney General Scott Pruitt, is still awaiting confirmation.
It's also not abnormal for administrations to restrict access to government scientists. In 2013, a statement by the Society of Environmental Journalists called the EPA under former-President Obama "one of the most closed, opaque agencies to the press."
"It's certainly the case that every administration tries to control information, but I think that what we're seeing here is much more sweeping than has ever been done before," said Andrew Light, the distinguished senior fellow in the Global Climate Program at the nonpartisan World Resources Institute. "And in particular, it's noteworthy that it seems to be aimed at a cluster of science-driven agencies that primarily work on the environment and climate change."
While previous administrations have restricted government scientists' communications to the public, controlling their scientific conclusions is far more rare.
Perhaps the most notable case came in 2003, when the administration of President George W. Bush tried to alter the climate change section of a major EPA report on the environment. According to the Union of Concerned Scientists, which tracks such issues, changes included the deletion of a 1,000 year temperature record and insertion of a study funded by the American Petroleum Institute.
Many federal agencies employ scientists to help conduct research. Those findings are crucial in ensuring that regulations and government policy are based on the best information available. Data collected by federal scientists is also used by state and local governments as well as private industry.
The EPA's policy, like those of other technical agencies within the government, is designed to encourage its scientists to participate in the scientific process. To that end, the agency's official policy is to "encourage publication and presentation of research findings in peer-reviewed, professional, or scholarly journals and at professional meetings."
There's a growing concern in the scientific community and among environmental organizations that the new administration might take aim at climate change research in particular. Trump has previously called climate change a hoax created by China to hurt the U.S. economy, though he later said he had an "open mind" on the issue. In the weeks before his inauguration, groups of scientists rushed to copy and preserve federal public climate data out of fear that it would be purged.
Ericksen said that under Trump, the EPA will focus on its "core mission, which is to protect the environment and protect human health."
When asked if climate change fit into that, he repeated that they'll focus on the core mission.
