This bill, the "No IRIS Act of 2025," would stop the Environmental Protection Agency (EPA) from using any assessment made by the Integrated Risk Information System (IRIS) program for several official actions. Specifically, the bill would bar the EPA from using IRIS assessments to: (1) develop, finalize, or issue a rule or regulation; (2) carry out any regulatory, enforcement, or permitting action; and (3) inform air toxics assessments or other mapping or screening tools. The bill was introduced in the House on February 18, 2025, and was referred to a subcommittee.
If this bill becomes law, the EPA would not be allowed to rely on IRIS-generated assessments when making regulations, enforcing rules, issuing permits, or creating air toxics maps and screening tools. That change would apply to any EPA action that would otherwise use IRIS assessments.
