United States of America (USA/499: Chemical substances (HS 2803))
EPA is proposing significant new use rules (SNURs) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for two chemical substances which were the subject of premanufacture notices. The two substances are identified generically as multi-walled carbon nanotubes (P-08-177) and single-walled carbon nanotubes (P-08-328). These substances are subject to TSCA section 5(e) consent orders issued by EPA. The consent orders require protective measures to limit exposures or otherwise mitigate the potential unreasonable risk. The proposed SNURs on these substances are based on and consistent with the provisions in the underlying consent orders. The proposed SNURs designate as a "significant new use'' the absence of the protective measures required in the corresponding consent orders. This action would require persons who intend to manufacture, import, or process either of these two substances for an activity that is designated as a significant new use by this proposed rule to notify EPA at least 90 days before commencing that activity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.
