EPA Sets SNUR for Carbon Nanotubes

The Environmental Protection Agency is issuing a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) for a bimodal mixture consisting of multi-walled carbon nanotubes and other classes of carbon nanotubes, it said in a final rule. As a result of the SNUR, persons planning to manufacture, import or process the carbon nanotube mixture for an activity that is designated as a significant new use by this rule are to notify EPA at least 90 days in advance. The final rule takes effect Nov. 2.
