EPA Demands 90-Day Heads-Up on New Chemicals
Published Date: 6/13/2025
Rule
Summary
The EPA is setting new rules for certain chemicals, making sure anyone who wants to make or use them in new ways tells the EPA 90 days ahead. This gives the EPA time to check if the new use is safe before it starts. If you work with these chemicals, get ready to follow these steps to keep things safe and legal!
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
90-Day Notice Required Before New Chemical Uses
If you manufacture, import, or process any of the listed chemical substances for a use the rule calls a “significant new use,” you must notify the EPA at least 90 days before starting. "Manufacture" includes import, and you cannot begin the new activity until EPA reviews the notice, makes a determination, and takes any required actions.
EPA Review Before New Uses Protects Public
When a business submits the required notification, EPA will evaluate the conditions of the proposed use and must review and make a determination before the new use can start. The 90-day-notice process gives EPA time to evaluate and take actions about the proposed use before it begins.
