EPA Extends Comment Period for Proposed CNT SNURs

On January 8, 2010, the U.S. Environmental Protection Agency (EPA) extended until February 8, 2010, the comment period for its November 6, 2009, proposed significant new use rules (SNUR) for multi-walled carbon nanotubes (CNT) and single-walled CNTs.  According to the January 8, 2010, notice, EPA received a request to extend the comment period.  On December 1, 2009, the U.S. World Trade Organization (WTO) Technical Barriers to Trade (TBT) Inquiry Point at the National Institute of Standards and Technology (NIST), on behalf of the European Economic Community (EEC) WTO TBT Enquiry Point, submitted a request to extend the comment period. According to the request, “the European Communities are currently reviewing the draft regulation,” and request that the comment deadline be extended. According to Charles Auer, formerly the Director of EPA’s Office of Pollution Prevention and Toxics (OPPT) and now affiliated with Bergeson & Campbell, P.C., this is the first request he is aware of from the EEC TBT Enquiry Point to OPPT. Auer noted that the EEC is not necessarily raising a trade concern, but may simply want to know the scope of the proposed regulation.

Federal Agencies Will Hold Workshop on Enabling Standards for Nanomaterial Characterization

The National Institute of Standards and Technology (NIST) will hold an October 8-9, 2008, workshop regarding enabling standards for nanomaterial characterization.  According to the workshop overview, there is an “urgent need” to elevate new protocols and practices for characterizing the physicochemical properties of nanomaterials, and their in vitro and in vivo properties with respect to biological systems, to that of internationally accepted standards to accelerate research, development, risk identification, regulation, and widespread public adoption of nanotechnology. The workshop is intended to address this need on several fronts. Workshop sponsors and contributors include:  ASTM International; Food and Drug Administration (FDA); Nanotechnology Characterization Laboratory (NCL) at NCI-Frederick; National Cancer Institute (NCI); National Institute for Occupational Safety and Health (NIOSH); NIST; National Institute of Environmental Health Sciences (NIEHS); and Oregon Nanoscience and Microtechnologies Institute (ONAMI).  The workshop is limited to 100 attendees.

Researchers Examine Nanomaterials in Food Chain

 

The August 2008 issue of Environmental Health Perspectives includes an article entitled “Nano-Food Chain Link Examined,” which reports on recent research by the U.S. National Institute of Standards and Technology (NIST) regarding whether nanomaterials biomagnify in the food chain. NIST reports that certain nanomaterials may not accumulate in the food chain, but notes that additional research is necessary before any generalizations can be made regarding environmental and human safety of nanomaterials.
