What is a Significant New Use Rule (SNUR) and how does it relate to Nanotechnology?
A Significant New Use Rule (SNUR) is a regulatory tool under TSCA that allows the EPA to require notification before a chemical substance is used in a new way that might create different or additional exposures or risks. For nanomaterials, SNURs can be used to ensure that any new uses are reviewed by the EPA before they are implemented, allowing for better risk management.
