## Summary

**Strengthen scientific standards and interagency coordination for chemical risk evaluations under TSCA.** This bill would tighten testing rules, require coordinated review among federal agencies, and add formal peer review and worker‑protection steps to how EPA evaluates chemical risks. - Workers: EPA would have to consult with OSHA and other departments and weigh input from industrial hygiene, toxicology, engineering, and process safety experts when deciding whether a unique worker protection standard is needed. This aims to better align workplace protections with chemical risk findings. - Federal agencies and scientists: The bill would create a formal interagency review giving agencies not less than 30 days to submit information and comments on draft risk evaluations before public notice. It also lengthens certain review windows to 60 days, requires EPA to consider exposure limits developed by other agencies, and adds in-person peer review with at least 30 days for reviewers to examine the science used in evaluations. - Manufacturers and registrants: Testing rules would require technically feasible methods, ask that testing requests state intended and known uses, and rely on OECD test guidelines that EPA must identify and update at least once every 2 years. The bill also removes a clause that previously said some actions were made "without consideration of costs or other nonrisk factors", and it requires selection of cost‑effective risk‑mitigation measures that do not create greater risks.

## Provisions PRIA read

The bill would also remove a rule that actions must be made without considering costs, allowing EPA t…
- Changes to how EPA reviews chemical risks: mixed, medium. If enacted, the bill would make EPA get formal interagency input when doing TSCA risk evaluations and give other agencies at least 30 days to comment before public notice. EPA would have to consider exposure limits from other federal agencies and not assume noncompliance with laws like OSHA. Risk e…
- New rules for chemical testing: mixed, low. If enacted, the bill would require EPA to use identified OECD test guidelines where relevant when setting accepted test methods. The agency would update its official list of test methods at least once every 2 years. Testing plans would have public notice and comment on both the plan and each propos…
