On September 21, EPA published significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 107 chemical substances that were the subject of premanufacture notices. Eight of the chemicals are also subject to TSCA consent orders issued by EPA. The rule is effective on November 20, 2012.

Under the new SNURs, anyone who intends to manufacture, import, or process any of the listed 107 chemical substances for any activity that EPA designates as a significant new use must notify EPA at least 90 days before beginning the activity. EPA will, in turn, evaluate the intended activity, and, if necessary, prohibit or limit the activity before it occurs.
