Environmental Protection Agency Administrator Scott Pruitt’s recent announcement that EPA will not use “secret science” — that is science for which the underlying data is not available — is challenging. Whereas EPA is routinely in receipt of unpublished toxicity studies for chemicals designed for commerce, not all important scientific findings are publishable. Nor do scientific journals generally have sufficient space to include all data.

Much has been made in recent weeks of this new EPA policy, including an op-ed opposing it by former EPA Administrator Gina McCarthy and former acting Assistant Administrator Janet McCabe.
