EPA issues a Federal Register notice regarding carbon nanotubes

(Nanowerk News) On Friday, October 31st, 2008, the U.S. Environmental Protection Agency (EPA) issued a Federal Register notice regarding carbon nanotubes (CNTs). The notice reminds manufacturers and importers that they must notify EPA 90 days prior to the manufacture or import of new chemical CNTs for commercial purposes, in accordance with TSCA Section 5 regulations for new chemicals at 40 C.F.R. 720.22.
This document gives notice of the Toxic Substances Control Act (TSCA) requirements potentially applicable to carbon nanotubes (CNTs).
EPA generally considers CNTs to be chemical substances distinct from graphite or other allotropes of carbon listed on the TSCA Inventory. Many CNTs may therefore be new chemicals under TSCA section 5.
Manufacturers or importers of CNTs not on the TSCA Inventory must submit a premanufacture notice (PMN) (or applicable exemption) under TSCA section 5 where required under 40 CFR part 720 or part 723. In order to determine the TSCA Inventory status of a CNT, a manufacturer may submit to EPA a bona fide intent to manufacture or import under 40 CFR 720.25.
If CNT manufacturers or importers have any questions regarding their TSCA requirements, they should contact Jim Alwood at EPA at 202-564-8974 or alwood.jim@epa.gov
