Trump EPA Erects New Barriers To Crucial Science

A new EPA rule will make it more difficult for the regulators to use some scientific studies about the connection between pollution and health.

The Environmental Protection Agency adopted a new rule restricting the types of scientific studies its own regulators can use to rein in pollution, in the Trump administration’s latest effort to undercut the use of science in establishing public health standards.

The rule goes into effect on Wednesday and applies to all future EPA regulations. It puts a premium on scientific studies that are based on underlying data that is available to other scientists or to the public. Studies that do not meet that standard, which could include major epidemiological studies, will be given less weight by regulators unless the head of the EPA personally intervenes. The rule also requires that the agency disclose which studies it uses to set future pollution limits.

“The American public deserves to know which studies we are using to craft our regulations, which of those studies are key or pivotal to our decisions and, to the extent possible, that data should be available for the public to see,” EPA Administrator Andrew Wheeler said in an announcement about the rule. The event was hosted by the conservative think tank the Competitive Enterprise Institute.
