Significant New Use Rules on Certain Chemical Substances (24-5.5e)
What happened
Donald Trump signed significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for specific chemical substances. These rules apply to chemicals that were subject to premanufacture notices (PMNs) and an EPA Order. Persons must notify EPA 90 days before manufacturing or processing these chemicals for a designated significant new use, including import. Manufacturing or processing for a significant new use cannot start until EPA reviews the notification, makes a determination, and takes required actions.
Why it matters
These rules ensure EPA evaluates new uses of certain chemical substances before they commence, giving the agency oversight. This process initiates EPA's assessment of the conditions for new chemical uses. This helps regulate potentially harmful activities with these chemicals, preventing them from being used without prior review and approval.
