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

The Canada-U.S. Regulatory Cooperation Council (RCC) will hold a webinar on November 28, 2012, on its RCC Nanotechnology Work Plan. Canada and the U.S. created the RCC to align better their regulatory approaches in a number of areas, including nanotechnology. According to the U.S. Environmental Protection Agency (EPA), the purpose of the RCC’s nanotechnology initiative is to increase, where possible, regulatory transparency and coordination between the U.S. and Canada respecting nanomaterials. The Nanotechnology Work Plan includes specific objectives, deliverables, and milestones for tangible progress within the RCC’s two-year mandate. During the November 28, 2012, webinar, RCC will provide additional background information, as well as updates on ongoing activities under the Nanotechnology Work Plan. Stakeholders should confirm their webinar attendance no later than October 25, 2012.

On September 5, 2012, the National Research Council (NRC) released a pre-publication version of a report entitled Science for Environmental Protection:  The Road Ahead. The U.S. Environmental Protection Agency (EPA) asked NRC to assess EPA’s overall capabilities “to develop, obtain, and use the best available scientific and technologic information and tools to meet persistent, emerging,

On August 1, 2012, the U.S. Environmental Protection Agency (EPA) posted a final report entitled Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray, which EPA states “is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in

According to a July 10, 2012, memorandum added to the registration review docket for nanosilver, the Federal Register notice announcing the opening of the docket erroneously listed the comment period end date as August 19, 2012. The U.S. Environmental Protection Agency (EPA) memorandum states that the comment period has been extended to September 10, 2012

The U.S. Environmental Protection Agency (EPA) announced on July 2, 2012, the availability of an external review draft document entitled Nanomaterial Case Study: A Comparison of Multiwalled Carbon Nanotube and Decabromodiphenyl Ether Flame-Retardant Coatings Applied to Upholstery Textiles (EPA/600/R-12/043A). EPA states that the draft document “does not draw conclusions regarding potential environmental risks or hazards of multiwalled

On April 16, 2012, the Natural Resources Defense Council (NRDC) filed its brief in its lawsuit against the U.S. Environmental Protection Agency (EPA) concerning EPA’s conditional registration for HeiQ AGS-20, an end-use product containing nanosilver. NRDC filed suit on January 26, 2012, in the U.S. Court of Appeals for the Ninth Circuit (California) against EPA, seeking to limit public exposure to the nanosilver’s use in clothing, baby blankets, and other textiles and prevent EPA “from allowing nanosilver on the market without the legally-required data about its suspected harmful effects on humans and wildlife.”

On April 4, 2012, the U.S. Environmental Protection Agency (EPA) promulgated, through a direct final rule, significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). This includes a SNUR for “infused carbon nanostructures (generic).” According to EPA, the PMN states that the generic (non-confidential) use of the substance is

On February 9, 2012, the U.S. Environmental Protection Agency (EPA) posted a summary report on its January 2011 workshop on nanoscale silver. The workshop was the second in a series conducted by the National Center for Environmental Assessment (NCEA) to further the development of a research strategy for completing comprehensive environmental assessments of nanomaterials.  The basis of the workshop was the report Nanomaterial Case Study:  Nanoscale Silver in Disinfectant Spray.  According to the summary report, the outcomes of this and future workshops in the series — prioritized information gaps and risk tradeoffs — will be used in developing and refining a long-term research strategy to assess potential human health and ecological risks of nanomaterials and to manage associated risks of specific nanomaterials.
