HR 1415 United States House · 119th Congress

No IRIS Act of 2025

The No IRIS Act of 2025 (HR 1415) prohibits the Environmental Protection Agency (EPA) from using scientific assessments generated by its Integrated Risk Information System (IRIS) program to develop environmental regulations, enforce laws, issue permits, or inform air toxics mapping tools. This bill directly restricts the EPA’s regulatory process by banning IRIS data from key decision-making steps in environmental rulemaking. The law requires the EPA to rely on alternative scientific data for these purposes, without altering the IRIS program itself. It does not change existing EPA authority but limits how specific assessments may be applied in regulatory actions.
