On October 5, 2012, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) for potassium titanium oxide, which was previously the subject of a consent order under Section 5(e) of the Toxic Substances Control Act (TSCA). EPA states that, based on test data on the premanufacture notice (PMN) substance and structure…

On December 30, 2011, the U.S. Environmental Protection Agency (EPA) Office of Inspector General (OIG) released a report entitled EPA Needs to Manage Nanomaterial Risks More Effectively. According to OIG, the purpose of its review was to determine how effectively EPA is managing the human health and environmental risks of nanomaterials. OIG states that it found “that EPA does not currently have sufficient information or processes to effectively manage the human health and environmental risks of nanomaterials.” According to OIG, although EPA has the statutory authority to regulate nanomaterials, it “currently lacks the environmental and human health exposure and toxicological data to do so effectively.” EPA proposed a policy, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), that would identify new pesticides being registered with nanoscale materials.  After “minimal industry participation” in EPA’s Nanoscale Materials Stewardship Program (NMSP), a voluntary data collection program, EPA has chosen to propose mandatory reporting rules for nanomaterials under FIFRA, and is developing proposed rules under the Toxic Substances Control Act (TSCA).…

The U.S. Environmental Protection Agency (EPA) published on December 28, 2011, proposed significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). Of particular interest, seven of the PMN substances’ reported chemical names include the term “carbon nanotube” (CNT) or “CNT.”  EPA states that because of a lack of established nomenclature for CNTs, the Toxic Substances Control Act (TSCA) Inventory names for CNTs are currently in generic form, e.g., “carbon nanotube (CNT), multi-walled carbon nanotube (MWCNT), double-walled carbon nanotube (DWCNT), or single-walled carbon nanotube (SWCNT).” EPA uses the specific structural characteristics provided by the PMN submitter to characterize more specifically the TSCA Inventory listing for an individual CNT. According to EPA, all submitters of new chemical notices for CNTs have claimed those specific structural characteristics as confidential business information (CBI). The proposed rule includes the generic chemical name along with the PMN number to identify that a distinct chemical substance was the subject of the PMN without revealing the confidential chemical identity of the PMN substance. Comments are due January 27, 2012.…

The Office of Environmental Health Hazard Assessment (OEHHA) has posted comments received on its July 29, 2011, revised proposed regulation concerning the specification of hazard traits, environmental and toxicological endpoints, and other relevant data that are to be included in California’s Toxics Information Clearinghouse.  The California Department of Toxic Substances Control (DTSC) will use information…

On September 22, 2011, during a meeting of nano interests in Washington, D.C., the following people spoke:

  • Jeffrey Weiss, Senior Director, Technical Barriers to Trade, Office of the United States Trade Representative, “U.S. Trade Policy and Nanotechnology”;
  • Richard A. Canady, Ph.D., Director, Center for Human Health Risk Assessment Research Foundation, International Life Sciences

The Office of Environmental Health Hazard Assessment (OEHHA) announced on July 29, 2011, that it revised its proposed regulation concerning the specification of hazard traits, environmental and toxicological end-points, and other relevant data that are to be included in California’s Toxics Information Clearinghouse.  The California Department of Toxic Substances Control (DTSC) will use information from the Clearinghouse to help identify chemicals of concern in consumer products as part of its Green Chemistry Program. Comments are due September 12, 2011.…

The U.S. Environmental Protection Agency’s (EPA) July 7, 2011, 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 recast of the Directive on the Restriction of Hazardous Substances (RoHS) was published in the July 1, 2011, Official Journal of the European Union. The notice calls for the restriction of other hazardous substances and their substitution by more “environmentally friendly alternatives” as soon as scientific evidence is available, and taking into account the…

On May 6, 2011, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as multi-walled carbon nanotubes (MWCNT), which was the subject of premanufacture notice (PMN) P-08-199. Under the final SNUR, persons intending to manufacture, import, or process MWCNT for a use that is designated as a significant new use by the final rule must notify EPA at least 90 days before commencing that activity. EPA states that it believes the final rule is necessary “because the chemical substance may be hazardous to human health,” and 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. The final rule will be effective June 6, 2011.…

On April 6, 2011, several members of the NanoSafety Consortium submitted to the U.S. Environmental Protection Agency (EPA) a proposed testing agreement under Section 4 of the Toxic Substances Control Act (TSCA). Under the proposed testing agreement, the substances to be tested may include multi-walled carbon nanotubes, double-walled carbon nanotubes, single-walled carbon nanotubes, and graphene nanoplatelets. Participants…
