On September 22, 2010, the California Department of Toxic Substances Control (CDTSC) and the U.S. Environmental Protection Agency (EPA) held a public workshop on state and federal nanomaterial activities. During the workshop, CDTSC and EPA discussed the results of California’s data call-in (DCI) for carbon nanotubes (CNT), its plans for future DCIs, and EPA’s efforts related to CNTs. The candidate chemicals for CDTSC’s second DCI, which it intends to issue this Fall, include...

On September 17, 2010, the U.S. Environmental Protection Agency (EPA) issued final significant new use rules (SNUR) for two chemical substances that were the subject of premanufacture notices (PMN). The two chemical substances are identified generically as multi-walled carbon nanotubes (MWCNT) (PMN P08177) and single-walled carbon nanotubes (SWCNT) (PMN P08328). Persons who intend to manufacture, import, or process either of these substances for a use that is designated as a...

The California Department of Toxic Substances Control (CDTSC) has rescheduled its workshop on state and federal nanomaterial activities for September 22, 2010. CDTSC, the U.S. Environmental Protection Agency (EPA), and the University of California, Los Angeles (UCLA) are cosponsoring the workshop to discuss the results of California’s carbon nanotube (CNT) information call-in, future data call-in requests for additional nanomaterials, and federal efforts related to CNTs for...

According to the California Department of Toxic Substances Control’s (CDTSC) website, it is drafting a memorandum of understanding (MOU) with the U.S. Environmental Protection Agency (EPA) to facilitate information exchange, collaboration, and outline a working partnership on emerging chemicals, green chemistry, and materials management. Under the new MOU, EPA and CDTSC will: 1.  Establish chemical specific teams for priority chemicals of mutual interest;...

On August 13, 2010, the U.S. Environmental Protection Agency (EPA) announced that it is proposing to register conditionally a pesticide product containing nanosilver as a new active ingredient for a period of four years. According to EPA, the antimicrobial pesticide product, HeiQ AGS-20, is a silver-based product that is proposed for use as a preservative for textiles. As a condition of registration, EPA is proposing to require additional product chemistry, toxicology, exposure, and...

On August 13, 2010, the U.S. Environmental Protection Agency (EPA) announced the availability of a draft document entitled Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray, which EPA intends to serve as part of a process to help identify and prioritize scientific and technical information that could be used in conducting comprehensive environmental assessments of selected nanomaterials. EPA states that the Case Study does not attempt to draw conclusions regarding potential...

Due to California’s budget issues and resulting furlough for civil service employees, the California Department of Toxic Substances Control (CDTSC) has postponed its August 13, 2010, workshop on state and federal nanomaterial activities. CDTSC, the U.S. Environmental Protection Agency (EPA), and the University of California, Los Angeles (UCLA) are cosponsoring the workshop to discuss the results of California’s carbon nanotube (CNT) information call-in, future data call-in requests for...

According to the Office of Management and Budget (OMB) website, on July 30, 2010, OMB received from the U.S. Environmental Protection Agency (EPA) a notice concerning “Pesticide Products Containing Nanoscale Materials.” No additional information regarding the notice is available on OMB’s website. During the April 29, 2010, meeting of EPA’s Pesticide Program Dialogue Committee (PPDC), William Jordan, Senior Policy Advisor, Office of Pesticide Programs (OPP), stated that EPA was in the...

The August 2010 issue of the National Institute of Environmental Health Sciences (NIEHS) Environmental Factor includes an article regarding the Intramural NanoHealth Signature Program, which is intended to investigate the health effects of engineered nanomaterials (ENM) in susceptible populations. According to the article, ENMs are increasingly found in medications, cosmetics, electronics, and other consumer products, creating environmental as well as occupational...

On July 28, 2010, the U.S. Environmental Protection Agency (EPA) published a Federal Register notice announcing that it is reopening the comment period for its February 3, 2010, proposed significant new use rule (SNUR) for the chemical substance identified generically as multi-walled carbon nanotubes (P-08-199).  According to the July 28, 2010, notice, a commenter noted that neither the proposed rule nor the docket contained specific carbon nanotube data or data supporting the nature of the...
