EPA has published final significant new use rules (SNURs) for two carbon nanotubes that would require companies to provide the agency with 90 days’ notice before they manufacture or import them. 75 Fed. Reg. 56,880 (9/17/10). The new rules would also require that any covered company comply with restrictions EPA has already imposed on the original manufacturer. They would require any new manufacturer to protect its workers by having employees wear gloves and full-body clothing impervious to the carbon nanotubes, and employees who would be reasonably likely to inhale the carbon nanotubes would have to wear a NIOSH full-face respirator. The two chemical substances covered by the rules are identified generically as multi-walled carbon nanotubes (PMN P-08-177) and single-walled carbon nanotubes (PMN P-08-328). The final rule is effective October 18, 2010.
