To direct that certain assessments with respect to toxicity of chemicals be carried out by the program offices of the Environmental Protection Agency, and for other purposes.

Summary
What This Bill Does
This bill reorganizes how the EPA assesses the health risks of toxic chemicals. It transfers chemical hazard assessments from the EPA centralized Integrated Risk Information System (IRIS) program to individual EPA program offices (Water, Air, Land, Chemical Safety). It also creates a new steering committee to coordinate these assessments and establishes new scientific standards that emphasize non-linear dose-response modeling.
Who Benefits and How
Chemical manufacturers and industries that use or produce potentially toxic chemicals benefit from this bill. The new scientific standards favor non-linear dose-response approaches, which typically result in higher allowable exposure thresholds compared to the traditional linear models used for carcinogens. Industries also benefit from decentralized assessments that may be more responsive to their regulatory needs and less rigorous than centralized IRIS reviews.
Who Bears the Burden and How
Public health and environmental groups may face weaker protections as the decentralized assessment process could reduce scientific rigor and independence. The EPA Office of Research and Development loses its central role in chemical assessments, with authority dispersed to program offices that may be more subject to industry influence. Communities near industrial facilities may face increased health risks if toxicity standards are weakened.
Key Provisions
- Transfers IRIS chemical assessments to individual EPA program offices rather than centralized scientific review
- Creates a 15-member steering committee to coordinate assessments and consider third-party assessments
- Mandates scientific standards emphasizing non-linear dose-response modeling, which typically results in less protective exposure limits
