What it does
This bill redirects chemical safety assessments from EPA's centralized Integrated Risk Information System (IRIS) program to individual EPA program offices (Water, Air, Chemical Safety, etc.), requiring them to assign toxicity values and maintain a shared database. It establishes a steering committee to prevent duplication and mandates that all assessments follow specified scientific standards and be reported to Congress every two years.
Why we flagged it
The bill's core mechanism is organizational: it shifts authority for chemical toxicity assessments from a centralized EPA program (IRIS) to distributed program offices. This is a structural change to how EPA conducts science, not a new substantive protection or restriction.
What the text implies
- Decentralization may reduce transparency: IRIS assessments were published in a single, searchable database; fragmented assessments across program offices may be harder for the public, states, and industry to locate and compare.
- Program offices have discretion to determine 'need' for assessments (section 7(b)), potentially allowing regulatory priorities to override scientific completeness—a chemical may not be assessed if a program office deems it outside its mandate.
