Yesterday, U.S. EPA issued Significant New Use Rules (SNURs) for 35 substances which were subject to Premanufacture Notices (PMNs) under the Toxic Substances Control Act (TSCA). The SNURs were promulgated as a Direct Final Rule, and take effect starting April 14, 2014.
Fourteen of the substances, including various polyfluorinated alkyl compounds and multi-walled carbon nanotubes, are subject to “risk-based” TSCA § 5(e) consent orders which require use of protective measures to limit exposure or otherwise mitigate risk; the SNURs for these substances designate as a significant new use the absence of these protective measures. The SNURs for the other 21 substances designate various significant new uses, including releases to water as well as certain industrial, commercial and consumer activities, and establish certain protection in the workplace requirements, such as the use of respirators.
Written adverse or critical comments, or notice of intent to submit such comments, must be received by E.P.A. by March 14, 2014.
