US environmental regulators now approve new chemical uses, not just track them
What happened
US environmental regulators just tightened the rules for certain chemicals. Companies that want to use these chemicals in new ways must now get approval and wait 90 days, instead of just telling the agency they plan to do so.
Why it matters
For specific chemicals, companies can no longer simply notify the agency and proceed with a new use. They now face an additional hurdle and potential delays, as the agency must review and approve the use first. This means US environmental regulators can require risk management actions before a new use begins, rather than reacting after the fact.
The signal
Watch how many new use notices are submitted for these chemicals, and how often the agency requires risk management actions or denies a proposed use.
