A federal panel of independent scientific experts says the EPA has flouted the panel’s guidance in its efforts to roll back a number of Obama-era regulations, resulting in an agency push that will affect public health for millions of Americans without the consideration of environmental science.

The EPA’s Science Advisory Board (SAB) wrote in four draft reports published online Tuesday that the agency’s published revisions to at least four regulations “conflict with established science,” according to the Washington Post.

Although two-thirds of the SAB’s current members are Trump appointees, Juliet Eilperin wrote in the Post, the panel “found serious flaws” in the proposed changes to rules governing pollution, gas mileage, and how regulations are written.

The revisions and regulatory rollbacks in question include:

• a reversal of a rule that limits the use of pesticides and other chemicals near waterways, which the SAB says “neglects established science” that has shown how contamination from such toxins can pollute drinking water
• a reduction in mileage targets for vehicles, which was decided based on “implausible” economic analyses
• the rollback of the Mercury and Air Toxics Standards (MATS), which the EPA pushed after performing a flawed cost-benefit analysis, failing to consider the public health benefits and savings that would result from controlling mercury pollution
• the EPA’s push to exclude certain scientific studies from policy-making, saying the change “could easily undercut the integrity of environmental laws, as it will allow systematic bias to be introduced.”
