EPA will withdraw significant new use rules (SNUR) for carbon nanomaterial (generic)

Date: 04/12/2018

The U.S. Environmental Protection Agency (EPA) is scheduled to publish a Federal Register notice withdrawing significant new use rules (SNUR) promulgated under the Toxic Substances Control Act (TSCA) for 26 chemical substances, including carbon nanomaterial (generic), that were the subject of premanufacture notices (PMN).

The Federal Register notice is available here.

As previously reported, EPA issued the SNURs through a direct final rule in October 2018.

EPA states that it received adverse comments regarding the SNURs identified in the direct final rule, and is withdrawing them.

In October, the EPA also issued proposed SNURs covering these 26 chemical substances. EPA states that it will address all adverse public comments in a subsequent final rule, based on the proposed SNURs.
