EPA Regulatory Agenda Includes Several Notices Concerning Nanoscale Materials

Lynn L. Bergeson

The U.S. Environmental Protection Agency’s (EPA) December 20, 2010, Regulatory Agenda includes several notices concerning nanoscale materials:

  • Test Rule for Certain Nanoscale Materials — EPA states that it is developing a test rule under Section 4(a) of the Toxic Substances Control Act (TSCA) to require manufacturers (defined by statute to include importers) and processors of the multiwall carbon nanotube described in Premanufacture Notice (PMN) P-08-199, certain clays (e.g., kaolin (including halloysite) and bentonite (including montmorillonite)), alumina, and spray-applied nanomaterials to conduct testing for health effects, ecological effects, and environmental fate, as well as provide material characterization data. EPA intends to issue a notice of proposed rulemaking (NPRM) in April 2011.
  • Reporting Under TSCA Section 8(a) — Under TSCA Section 8(a), EPA is developing a proposal to establish reporting requirements for certain nanoscale materials.  According to the notice, the rule would propose that persons who manufacture these nanoscale materials notify EPA of certain information including production volume, methods of manufacture and processing, exposure and release information, and available health and safety data. The notice states that EPA intends to issue an NPRM in February 2011. EPA submitted a proposed rule to the Office of Management and Budget (OMB) for review on November 22, 2010.
  • Significant New Use Rule (SNUR) — EPA is developing a SNUR for nanoscale materials under TSCA Section 5(a)(2).  The SNUR would require persons who intend to manufacture, import, or process this/these chemical substance(s) 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. EPA intends to issue an NPRM in February 2011.
