On March 3, 2020, the United States Environmental Protection Agency released a “Supplemental notice of proposed rulemaking” for the Agency’s previously proposed rule entitled “Strengthening Transparency in Regulatory Science.”  EPA explained in its notice:

“This supplemental notice of proposed rulemaking (SNPRM) includes clarifications, modifications and additions to certain provisions published on April 30, 2018. This SNPRM proposes that the scope of the rulemaking apply to influential scientific information as well as significant regulatory decisions. This notice proposes definitions and clarifies that the proposed rulemaking applies to data and models underlying both pivotal science and pivotal regulatory science. In this SNPRM, EPA is also proposing a modified approach to the public availability provisions for data and models that would underly significant regulatory decisions and an alternate approach. Finally, EPA is taking comment on whether to use its housekeeping authority independently or in conjunction with appropriate environmental statutory provisions as authority for taking this action.”
