No IRIS Act of 2025
Summary
What This Bill Does
The No IRIS Act of 2025 bars the Environmental Protection Agency Administrator from using any assessment generated by EPA's Integrated Risk Information System program to develop, finalize, or issue a rule or regulation; carry out regulatory, enforcement, or permitting action; or inform air toxics assessments or mapping and screening tools. IRIS assessments are chemical hazard and toxicity evaluations that often inform later regulatory decisions. The bill would sharply reduce IRIS's legal influence inside EPA, benefiting regulated parties that challenge IRIS assumptions while burdening health-protection staff who rely on those assessments.
Who Benefits and How
Chemical manufacturers benefit because EPA could not use IRIS assessments as support for regulatory or permitting actions. Industrial permit applicants benefit from reduced risk that IRIS toxicity values drive permit limits or enforcement. Utilities with air-toxics exposure benefit if IRIS assessments cannot inform air toxics screening tools. Regulatory defense attorneys benefit from a statutory bar against EPA reliance on IRIS in covered actions.
Who Bears the Burden and How
EPA risk-assessment staff lose a major pathway for using IRIS assessments in rules, permits, and enforcement. Environmental health researchers bear the policy burden of EPA being unable to use IRIS findings in screening tools. Communities near toxic releases may face higher risk if EPA cannot use IRIS assessments to inform protective decisions. State environmental agencies may lose federal IRIS-based support for air toxics and screening work.
