On October 31, 2022, in a Federal Register Notice (FRN), the Environmental Protection Agency (EPA) proposed significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 25 chemical substances that were subject to premanufacture notices (PMNs). This would require notifying the EPA at least 90 days before beginning any manufacturing or processing for the SNUR.
The affected chemicals include:
- Nonanamide, N,N-dimethyl;
- 2H-Pyran, tetrahydro-4-methyl; and
- Silane, halogenated (generic).
Comments will be accepted through November 30, 2022.
The complete list of affected chemical substances as well as details on applicability and processing requirements can be found in the FRN:
