Comment Period for proposed Significant New Use Rule on Carbon Nanotubes extended

Published: Thursday 14 January 2010

According to Bergeson & Campbell P.C. Nanotechnology Law Blog, the US Environmental Protection Agency (EPA) has extended the comment period for its Significant New Use Rule (SNUR) proposal for multi-walled and single-walled carbon nanotubes (CNTs) (published 6th November 2009). The deadline has been extended to the 8th February 2010, after ‘EPA received a request to extend the comment period.  On December 1, 2009, the U.S. World Trade Organization (WTO) Technical Barriers to Trade (TBT) Inquiry Point at the National Institute of Standards and Technology (NIST), on behalf of the European Economic Community (EEC) WTO TBT Enquiry Point, submitted a request to extend the comment period.’ 

Bergeson & Campbell P.C. Nanotechnology Law Blog reports that Charles Auer, formerly the Director of EPA’s Office of Pollution Prevention and Toxics (OPPT), ‘noted that the EEC is not necessarily raising a trade concern, but may simply want to know the scope of the proposed regulation.’
