New chemical uses now get a 90-day pause for US environmental review
What happened
US environmental regulators want companies to get approval before using certain chemicals in new ways. Manufacturers must now tell the agency 90 days in advance and wait for a decision before starting any new activity with these substances.
Why it matters
Companies could once develop new uses for chemicals and only face scrutiny after the fact. This proposed rule means US environmental regulators want to review potential risks before a new use begins. It puts the burden of proof and delay on manufacturers, rather than letting new uses proceed unchecked.
The signal
Watch for the final rule to see which specific chemicals and new uses are covered, and how quickly the US environmental regulators process the first few applications.
