No IRIS Act of 2025

Bill 119 s 623, also known as the "IRIS Act," aims to restrict the Environmental Protection Agency (EPA) from utilizing assessments produced by the Integrated Risk Information System (IRIS) as a primary data source in various decision-making processes. The bill specifically prohibits the EPA from using IRIS assessments as a tier 1 data source in rulemakings, enforcement actions, permitting decisions, and other regulatory activities.

The Integrated Risk Information System is a program within the EPA that evaluates the potential health risks of various chemicals and substances. However, some critics argue that the assessments produced by IRIS are not always scientifically sound or reliable, leading to potentially flawed regulatory decisions by the EPA.

If passed, this bill would require the EPA to seek alternative sources of data and information when making important regulatory decisions, in order to ensure that the agency is using the most accurate and up-to-date information available. Proponents of the bill believe that this will lead to more effective and evidence-based environmental regulations. Overall, Bill 119 s 623 seeks to improve the transparency and reliability of the EPA's decision-making processes by limiting the use of potentially flawed assessments from the Integrated Risk Information System.
