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 18, 2012, the United States Department of Defense (DoD), General Services Administration (GSA), and National Aeronautics and Space Administration (NASA) promulgated a final rule amending the Federal Acquisition Regulation (FAR) to implement changes due to the Farm Security and Rural Investment Act that require contractors to report the biobased products purchased under service

On January 26, 2012, the Natural Resources Defense Council (NRDC) filed a lawsuit in the U.S. Court of Appeals for the Ninth Circuit against the U.S. Environmental Protection Agency (EPA) concerning its conditional registration of a pesticide product containing nanosilver as a new active ingredient for use as a preservative for textiles.  NRDC states that

On March 19, 2009, the California Department of Toxic Substances Control (CDTSC) will hold a full-day nanotechnology symposium on nanomaterials regulation from a variety of perspectives. According to CDTSC, the symposium will focus on the regulatory aspects of nanotechnology, the role of the U.S. Environmental Protection Agency (EPA), and CDTSC’s chemical information call-in program including nanoscale materials. CDTSC states that federal interest in nanomaterial regulation and California’s efforts “provide a great opportunity for fostering technological advances that recognize environmental and public health concerns. The goal is to create a partnership where we can enhance research where needed and promote sustainable processes as well as applications.” Registration is required. The symposium will also be available via web cast.

The Environmental Defense Fund (EDF) recently posted two blog items regarding a consent order negotiated by the U.S. Environmental Protection Agency (EPA). The October 9, 2008, item states that EPA intends to issue a sanitized version of a consent order negotiated with a producer of multiwalled carbon nanotubes (MWCNT). According to EDF, the order was prompted by EPA’s review of a premanufacturing notification (PMN).

The International Agency for Research on Cancer (IARC) recently solicited nominations for substances for review in future IARC Monographs, which identify environmental factors that can increase the risk of human cancer. IARC states that it will select substances for review based on: (a) evidence of human exposure; and (b) evidence or suspicion of carcinogenicity. The 51 substances nominated include carbon nanotubes, which received three nominations:

DuPont and Environmental Defense (ED) will hold two interactive workshops on nano risk management. The workshops are intended to give participants the tools they need to:

  • Understand (and explain to others) why nano-specific risk management is necessary;
  • Assemble and leverage the internal and external resources to implement nano-specific risk management; and
  • Begin implementing nano-specific risk

On November 19, 2007, Environmental Defense (ED) issued a press release that states that the National Nanotechnology Initiative (NNI) is not effectively addressing the potential risks of nanotechnology, and that a potential model for resolving the conflict between NNI’s dual charges to both promote and oversee the technology could be drawn from the Atomic Energy

On October 31, 2007, the House Committee on Science and Technology’s Research and Science Education Subcommittee held a hearing on the relationship between environmental and health policy and nanotechnology. The Subcommittee examined how the U.S. can stay at the forefront of scientific research and development, while at the same time establishing priorities and a detailed plan for research on the potential environmental and health risks of engineered nanomaterials. The Science and Technology Committee held two previous hearings on this issue — one in 2005 and another in 2006 — with the objective of reviewing the importance of risk research for achieving the potential benefits of nanotechnology and the efforts of the interagency National Nanotechnology Initiative (NNI) to put in place a research strategy. Progress in developing the research strategy has been slow, however. The hearing explored the status of the planning efforts and received suggestions from outside witnesses on ways to improve the process.

On October 3, 2007, the California Department for Toxic Substances Control (DTSC) held a symposium on the potential hazards of nanoparticles in the environment. According to DTSC, exploring environmentally safe processes in nanotechnology manufacturing is a component of the California Green Chemistry Initiative.  Under the Initiative, a multi-agency state team is exploring a different approach to environmental protection — transitioning away from managing toxic chemicals at the end of the life-cycle, to reducing or eliminating their use altogether.  DTSC states that this new approach is similar to measures adopted by the European Union (EU) and the Canadian government to encourage greater manufacturer responsibility.
