A subcommittee of the Senate Committee on Environment and Public Works held a hearing on October 3 to gauge expert opinion on the Environmental Protection Agency’s (EPA) “Strengthening Transparency in Regulatory Science” proposed rule. The proposed rule directs the EPA to use “peer-reviewed information, standardized test methods, consistent data evaluation procedures, and good laboratory practices to ensure transparent, understandable, and reproducible scientific assessments.” Two witnesses testified in favor of the rule, asserting it would ensure timely scientific and administrative accountability, while a third witness expressed concern that the rule is focused on reducing regulations, not promoting transparent or sound science.
