EPA Announces Receipt of CNT PMNs
In a January 5, 2009, Federal Register notice, the U.S. Environmental Protection Agency (EPA) announces receipt of several premanufacture notices (PMN) concerning multi-walled carbon nanotubes (CNT). Under Section 5 of the Toxic Substances Control Act (TSCA), EPA requires any person who intends to manufacture (defined by statute to include import) a new chemical (i.e., a chemical not on the TSCA Inventory) to notify EPA and comply with the statutory provisions pertaining to the manufacture of new chemicals. According to the notice, EPA received the CNT PMNs on September 17, 2008, and the projected end date was December 15, 2008. The submitter name is claimed as confidential business information (CBI). Comments on the PMNs are due February 4, 2009.
The notice includes the following information:
| Case No. | Use | Chemical |
| P-08-0733 | (G) (1) A reinforcement for composites: Open, non-dispersive use; (2) A conductive additive for composites: Open, non-dispersive use; (3) A conductive additive for batteries: Contained use | (G) A multi-walled CNT |
| P-08-0734 | (G) (1) A reinforcement for composites: Open, non-dispersive use; (2) A conductive additive for composites: Open, non-dispersive use; (3) A conductive additive for batteries: Contained use | (G) A multi-walled CNT |
