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

On July 6, 2012, the U.S. Environmental Protection Agency (EPA) announced the establishment of a registration review docket for nanosilver. EPA states that registration review is its “periodic review of pesticide registrations to ensure that each pesticide continues to satisfy the statutory standard for registration, that is, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment.” Registration review dockets include information intended to assist the public in understanding the types of information and issues that EPA may consider during the course of registration reviews. According to the preliminary work plan, EPA has information that there are silver-based pesticide products that were registered without the registrant disclosing to EPA the presence or characteristics of the nanosilver in their products. EPA sent a letter in August 2009 to each registrant with silver-based products requesting a statement as to whether their products contained any amount of silver in any form having a dimension that measures between 1 and approximately 100 nanometers. Four registrants responded that their products, which were registered using data for conventional silver, contain nanosilver. In the preliminary work plan, EPA states it is identifying several other products, registered using data for silver chloride, as potentially containing nanosilver. The registration review for nanosilver includes these products, as well as the two HeiQ nanosilver products conditionally registered in December 2011. According to the preliminary work plan, EPA believes that additional data are needed to determine whether the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) standard for maintaining these registrations is met “due to nanosilver’s unique physical and chemical properties, and thus nanosilver’s potentially different health and safety properties as compared to silver.”

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 May 14, 2012, the U.S. Environmental Protection Agency (EPA) and the Department of Commerce announced efforts to launch an environmental technology initiative intended to help create American jobs in the growing environmental industry. EPA released a document entitled Technology Innovation for Environmental and Economic Progress: An EPA Roadmap, which states that EPA “will undertake policy

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
