CDTSC and EPA Hold Public Workshop on State and Federal Nanomaterial Activities

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 nanosilver, nano zero valent iron, nano titanium dioxide, nano zinc oxide, nano cerium oxide, and quantum dots. CDTSC may also include in the DCI a request for more information concerning CNTs incorporated in nanometals. According to CDTSC, the DCI will focus its initial questions on analytical test methods for the respective nanomaterial chemical, as well as its metabolites and breakdown products, in various matrices. The meeting presentations for each of the DCI candidates include more specific information regarding applications, production, human health and environmental concerns, why CDTSC is interested, and possible DCI questions.


Bush Administration Releases Principles for Nanotechnology Environmental, Health, and Safety Oversight

On November 8, 2007, the Office of Science and Technology Policy (OSTP) and the Council on Environmental Quality (CEQ) issued a memorandum regarding “Principles for Nanotechnology Environmental, Health, and Safety Oversight.” According to the memorandum, OSTP and CEQ “led a multi-agency consensus-based process” to develop principles intended to guide the development and implementation of policies for nanotechnology environmental, health, and safety oversight at the agency level.  The memorandum says that federal agencies such as the U.S. Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), the Occupational Safety and Health Administration (OSHA), and the National Institute for Occupational Safety and Health (NIOSH) “must implement sound policies to protect public health and the environment,” and “agencies that perform nanotechnology research and development or that use nanotechnology in accomplishing their mission must provide appropriate oversight.”

The memorandum states that these agencies should follow the following principles in developing policies for environmental, health, and safety oversight related to nanotechnology:

  • Purpose:  Federal oversight approaches should be cognizant of the potential benefits of nanotechnology, including health, economic, and environmental benefits, while recognizing uncertainties surrounding the evolving science and technology.  The purpose of considering environmental, health, and safety oversight approaches in the context of nanotechnology is to protect human health and the environment.
  • Current Understanding:  The federal government’s current understanding is that existing statutory authorities are adequate to address oversight of nanotechnology and its applications.  As with any developing area, as new information becomes available the federal government will adapt or develop additional oversight approaches, as necessary, to address the area of nanotechnology.
  • Information Development:  Adequate information should be developed with respect to the effects of nanomaterials on human health and the environment.  To the extent practicable and respecting confidential information (e.g., Confidential Business Information (CBI)), this information should be developed in an open and transparent manner by stakeholders, including the federal government and developers of nanomaterials.
  • Risk Assessment and Risk Management:  The federal government should use standard oversight approaches to assess risks and benefits, and manage risks, considering safety, health and environmental impacts, and exposure mitigation.  As experience is gained, these approaches can be refined.  The federal government should strive to reach an appropriate level of consistency in risk assessment and management approaches across the government.
  • International:  Recognizing the global efforts to develop nanotechnology, the federal government should proactively promote international cooperation.  The federal government should encourage coordinated and collaborative health and environmental research and test data development across the international community.  The federal government should also promote access to information across the international community.  These efforts will allow the federal government to contribute to, and take advantage of, risk assessment and risk management approaches, as appropriate, across the international community.
  • Regulatory Path Forward:  In light of the “Purpose” of oversight as described above, the federal government should consider the following, to the extent permitted by law and where applicable, in establishing environmental, health, and safety regulations for nanotechnology:
