WASHINGTON  – Today, the U.S. Environmental Protection Agency (EPA) announced an extension of the comment period on the proposed rule, “Strengthening Transparency in Regulatory Science.” EPA is also announcing a public hearing for the proposed rule, which will be held on July 17, 2018, in Washington, D.C.

“EPA is committed to public participation and transparency in the rulemaking process,” said EPA Administrator Scott Pruitt. “By extending the comment period for this rule and holding a public hearing, we are giving stakeholders the opportunity to provide valuable input about how EPA can improve the science underlying its rules.”

On April 30, 2018, EPA announced the proposed rule with a 30-day comment period that was scheduled to close on May 30. With today’s extension, the comment period will now close on August 16. EPA is soliciting comments on all aspects of the proposal and specifically on the issues identified in Section III. The public hearing will provide a forum for interested parties to present data, views, and arguments regarding EPA’s proposed rule.

The proposed rule will strengthen the science used in regulations issued by EPA. It will require that underlying scientific information be publicly available. Also, this rule is consistent with data access requirements for major scientific journals and builds upon Executive Orders 13777 and 13783.
