From Small Times:
The US Environmental Protection Agency (EPA) has issued a Federal Register notice regarding carbon nanotubes (CNTs).
The document gives notice of the Toxic Substances Control Act (TSCA) requirements potentially applicable to CNTs, reminding 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..
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.
