US EPA issues SNURs for two Carbon Nanotube Substances; receives multiple Nano Pre-Manufacture Notices

The US Environmental Protection Agency (EPA) has today announced Significant New Use Rulings (SNUR) for 13 chemical substances, and revealed that from 23 May 2013 to 30 September 2013 it received 249 Pre-Manufacutre Notices (PMN). Two of the SNURs apply to carbon nanotube (CNT) substances, and ten of the PMNs received are for nanomaterials.

The SNURs for both CNT-based substances enforce protective measures required by section 5(e) of the US Toxic Substances Control Act (TSCA). These were applied to the materials as the EPA found for each ‘that this substance may present an unreasonable risk of injury to human health and the environment’. The SNUR requires that any person not enforcing the particular measures described for the substances notify the EPA ‘at least 90 days before commencing that activity’ for safety evaluation.

PMNs were received for 10 nanomaterial-based substances – most of these provide all of the information requested by EPA. All ten of the materials incorporate carbon nanotubes.
