19 April, 2019, the US Environmental Protection Agency (EPA) announced 11 Significant New Use Rules on certain chemical substances. The deadline for notification and evaluation is May 20, 2019.

EPA is now proposing significant new use rules (SNURs) for 11 chemical substances subject to pre-production notification (PMN) under the toxic substances management act (TSCA). This measure requires that persons who produce (as required by law, including imports) or process these 11 chemicals notify the EPA at least 90 days prior to the commencement of a significant new use activity designated under the proposed regulations. If regulatory proposals are finalized, the production and processing of significant new use substances may not commence until significant new use announcements are submitted and the EPA reviews the announcements and makes appropriate decisions and takes necessary actions.

The 11 substance are as follows:
