H.R. 1415, titled the No IRIS Act of 2025 (also referred to as the No Industrial Restrictions in Secret Act of 2025), would bar the Environmental Protection Agency (EPA) Administrator from using any assessments generated by the Integrated Risk Information System (IRIS) program for federal regulatory actions. Specifically, the bill prohibits using IRIS assessments to develop, finalize, or issue rules; to conduct regulatory, enforcement, or permitting actions; or to inform air toxics assessments or other mapping or screening tools. The measure, if enacted, would restrict EPA’s reliance on IRIS as a basis for risk-based decision-making and shift the agency toward alternative methods or data sources for regulatory actions. In short, the bill aims to prevent EPA from using IRIS-derived toxicology assessments in rulemaking and related regulatory activities, potentially altering how federal environmental health risks are evaluated and addressed.
