The "No Industrial Restrictions in Secret Act of 2025," also known as the "No IRIS Act of 2025" , proposes to prohibit the Environmental Protection Agency (EPA) from using assessments generated by its Integrated Risk Information System (IRIS) program. This legislation establishes a comprehensive ban on the application of IRIS data across various EPA activities. Specifically, the bill mandates that the EPA Administrator may not use IRIS assessments to develop, finalize, or issue any rule or regulation. Furthermore, it prohibits their use in carrying out any regulatory, enforcement, or permitting actions. The legislation also prevents IRIS assessments from informing air toxics assessments or other mapping and screening tools, thereby significantly limiting their influence on environmental policy and risk evaluation.
