HB1415, the “No Industrial Restrictions in Secret Act of 2025” or “No IRIS Act of 2025,” would bar the Environmental Protection Agency from using assessments produced by its Integrated Risk Information System (IRIS) program in a wide range of agency actions. Specifically, the bill prohibits EPA from relying on IRIS assessments to develop, finalize, or issue rules and regulations, and also from using them in other regulatory, enforcement, or permitting actions.
The bill would also prevent EPA from using IRIS assessments to inform air toxics assessments and other mapping or screening tools. In practical terms, it would remove a major scientific risk-assessment resource from EPA decision-making and could affect how the agency evaluates chemical hazards, air pollution risks, and related environmental health issues.
Impact
If enacted, the bill would significantly limit EPA’s ability to use IRIS-derived scientific assessments in regulatory and enforcement processes, altering how the agency supports rulemaking, permitting, and environmental screening. It would not repeal IRIS itself, but it would prohibit federal regulators from relying on its assessments for key agency actions, potentially affecting existing and future EPA standards involving toxic substances, air toxics, and environmental risk mapping.
Sentiment
Based on the bill’s title and structure, the measure appears to reflect a skeptical or critical view of EPA’s use of IRIS assessments, framing them as secretive or overly restrictive. No committee transcript or vote data is available, so there is no recorded bipartisan debate or formal vote history in the provided materials. The bill’s introduction and referral indicate it is still in the early committee stage.
Contention
The main point of contention is likely the role of IRIS as a scientific basis for EPA regulation. Supporters of the bill would likely argue that IRIS assessments can drive burdensome regulation and should not be used in rulemaking or enforcement, while opponents would likely argue that removing IRIS from EPA decision-making weakens science-based environmental protections and public health safeguards. The bill’s prohibition on using IRIS for air toxics assessments and screening tools suggests additional concern from stakeholders focused on environmental justice, chemical safety, and pollution monitoring.
