EPA Issues Significant New Use Rules for 29 Chemical Substances

In the October 19, 2017 Federal Register, the Environmental Protection Agency (EPA) issued a direct final rule for Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA) for 29 chemical substances that were the subject of premanufacture notices (PMNs). All 29 chemical substances are subject to TSCA section 5(e) consent orders. As a result of the SNURs, any entity that intends to manufacture (which includes import) or process any of the 29 chemical substances for an activity that is designated as a significant new use within the SNURs must notify the EPA at least 90 days before the start of that activity to allow the EPA to evaluate the intended use beforehand.

If the EPA receives adverse or critical comments on one or more of the SNURs before November 20, 2017, EPA will withdraw the relevant sections of the direct final rule before it goes into effect on December 18, 2017.
