On July 28, 2020, in a Federal Register Notice (FRN), the Environmental Protection Agency (EPA) issued significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for seven chemicals.  This would require notifying the EPA at least 90 days before beginning any manufacturing or processing for the SNUR.

The affected chemicals include:

  • Phosphonium, tributylmethyl-, iodide (1:1);
  • Phosphorous acid, triisotridecyl ester; and
  • Metal oxide-chloro (generic).

The rule will be effective on September 28, 2020.

Details on applicability and processing requirements can be found in the FRN:
