Bill > S623

This bill, known as the "No IRIS Act of 2025," prohibits the Administrator of the Environmental Protection Agency (EPA) from using assessments generated by the Integrated Risk Information System (IRIS) program for several key purposes. Specifically, the EPA cannot use IRIS assessments as a basis for developing, finalizing, or issuing rules or regulations, conducting regulatory, enforcement, or permitting actions, or informing air toxics assessments or other mapping and screening tools. The IRIS program is a EPA database that evaluates information on human health effects that may result from exposure to environmental contaminants. By restricting the use of IRIS assessments, this bill would significantly limit the EPA's ability to rely on this specific scientific evaluation tool when making regulatory decisions, potentially impacting how the agency assesses and manages environmental and health risks. The bill appears to be aimed at constraining the EPA's regulatory authority by removing a key data source from its decision-making process.
