Federal Advisory Council on Occupational Safety and Health Considers Dispersible Engineered Nanomaterials

The Federal Advisory Council on Occupational Safety and Health (FACOSH) met on May 3, 2012, during which it discussed the use of occupational exposure levels (OEL) by the federal government. Because the Occupational Safety and Health Administration’s (OSHA) permissible exposure limits (PEL) have remained unchanged since their adoption on May 29, 1971, and do not account for advances in technology or the latest data, FACOSH asked its Emerging Issues Subcommittee to analyze federal agencies’ use of PELs. As part of its review, the Subcommittee identified other issues of interest, including dispersible engineered nanomaterials (DENM). A document entitled “Recommendations for Consideration by the U.S. Secretary of Labor on the Adoption and Use of Occupational Exposure Limits by Federal Agencies” includes the following text concerning DENMs:

  • OSHA defines nanomaterials as, “materials that have been purposefully manufactured, synthesized, or manipulated to have a size with at least one dimension in the range of approximately 1 to 100 nanometers and that exhibit unique properties determined by their size.”
  • Published scientific studies have indicated that at least some DENMs are biologically active, have produced toxicological reactions in the lungs of exposed experimental animals, and may readily penetrate intact human skin. While DENMs are truly an emerging issue and published results are not plentiful, scientists and federal agencies, such as NIOSH, continue to conduct research to understand fully the potential health effects of exposure.
  • Currently, both scientists and federal agencies agree that DENM toxicity depends heavily on the physical and chemical properties of the nanoparticles, such as particle size and size distribution, agglomeration state, shape, crystal structure, chemical composition, surface area, surface chemistry, surface charge, and porosity, and that these properties may differ substantially from those of the same material in macro-scale form.

EU Biocides Regulation Addresses Nanomaterials

On May 10, 2012, the Council of the European Union (EU) announced the adoption of a regulation concerning the placing on the market and use of biocidal products, which include insecticides, disinfectants, and repellents, but not medicines or agricultural pesticides. The regulation will take effect September 1, 2013, with a transitional period for certain provisions. The regulation incorporates the European Commission’s (EC) recommendation on the definition of a nanomaterial, and requires that, where nanomaterials are used in a product, the risk to the environment and to health be assessed separately. Labels would be required to include the name of all nanomaterials contained in biocidal products, followed by the word “nano” in brackets. The regulation states that “approval of an active substance shall not cover nanomaterials except where explicitly mentioned.”

U.S. Delegation May Present Nanotechnology Guidance at UN GHS Subcommittee Meeting

The U.S. delegation to the July 4-6, 2012, meeting of the United Nations (UN) Subcommittee of Experts on the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is considering presenting an information paper on how to classify nanomaterials under the GHS. According to Kathy Landkrohn, Occupational Safety and Health Administration (OSHA) Directorate of Standards and Guidance, the paper would be presented under a work group examining the types of physical and chemical properties listed on safety data sheets (SDS). Landkrohn stated that a lack of data has impeded the work group’s ability to create a separate hazard class for nanomaterials.

EPA Releases Roadmap on Technology Innovation for Environmental and Economic Progress

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, regulatory, financial, and voluntary actions, grounded in science, that will promote innovation along the entire continuum of technology development and deployment.” Specifically, according to the Roadmap, EPA “will advocate more cost-effective, innovative solutions that eliminate, or significantly reduce, adverse impacts to natural resources in a manner that promotes healthy, productive communities.” EPA states that its initial efforts will focus on four broad actions:

  1. Designing EPA policies, regulations, standards, permits, and procedures to leverage technology innovation;
  2. Catalyzing technology design, development, finance, commercialization, and adoption through partnerships with stakeholders;
  3. Stimulating cross-Agency consideration, development, commercialization, and adoption of breakthrough technologies; and
  4. Developing a new relationship with the investment community. EPA will take a number of steps to build relationships and improve communication.

NNI Agencies Announce New Nanotechnology Signature Initiative

On May 14, 2012, the agencies participating in the National Nanotechnology Initiative (NNI) announced the fourth Nanotechnology Signature Initiative, “Nanotechnology Knowledge Infrastructure:  Enabling National Leadership in Sustainable Design” (NKI). According to a press release issued by the National Nanotechnology Coordination Office (NNCO), this signature initiative will stimulate the development of models, simulation tools, and databases to enable the prediction of specific properties and characteristics of nanoscale materials.  This will then accelerate commercialization of nanotechnology innovations that maximize benefits to humans and the environment while minimizing risks. NKI identifies four areas that will benefit from focused attention:

  1. A diverse collaborative community of scientists, engineers, and technical staff to support research, development, and applications of nanotechnology to meet national challenges;
  2. An agile modeling network for multidisciplinary intellectual collaboration that effectively couples experimental basic research, modeling, and applications development;
  3. A sustainable cyber-toolbox to enable effective application of models and knowledge to nanomaterials design; and
  4. A robust digital nanotechnology data and information infrastructure to support effective data sharing, collaboration, and innovation across disciplines and applications.

SAICM Will Publish Comments on Adding Nanotechnology Activities to Global Plan of Action

The Strategic Approach to International Chemicals Management (SAICM) Secretariat is expected to publish this month comments on Switzerland’s proposal that activities relating to nanotechnology be added to the SAICM Global Plan of Action.  The proposal would include a new work area on nanotechnologies and manufactured nanomaterials, with corresponding activities, actors, and targets. The Secretariat will compile the comments to inform discussion at the third International Conference on Chemicals Management (ICCM3), which will be held September 17-21, 2012. The Nanotechnology Industries Association (NIA) submitted detailed comments on the proposal.

CRS Publishes Nanotechnology Policy Primer

The Congressional Research Service (CRS) published an April 13, 2012, document entitled Nanotechnology: A Policy Primer that provides an overview of federal research and development (R&D) in nanotechnology, U.S. competitiveness, environmental, health, and safety (EHS) concerns, nanomanufacturing, and public understanding of and attitudes toward nanotechnology. CRS states that, since the launch of the National Nanotechnology Initiative (NNI) in 2000 through fiscal year (FY) 2012, Congress has appropriated approximately $15.6 billion for nanotechnology R&D, including approximately $1.7 billion in FY 2012. President Obama has requested $1.8 billion in NNI funding for FY 2013. More than 60 nations have established similar programs, and, according to CRS, in 2010, the total global public R&D investments were approximately $8.2 billion, complemented by an estimated private sector investment of $9.6 billion.  Based on the data on inputs (e.g., R&D expenditures) and non-financial outputs (e.g., scientific papers, patents), the U.S. appears to be the overall global leader in nanotechnology, though CRS cautions that some believe the U.S. lead “may not be as large as it was for previous emerging technologies.” According to CRS, some research has raised concerns about the safety of nanoscale materials, and “[t]here is general agreement that more information on EHS implications is needed to protect the public and the environment; to assess and manage risks; and to create a regulatory environment that fosters prudent investment in nanotechnology-related innovation.”

EO on Promoting International Regulatory Cooperation Includes Emerging Technology

On May 1, 2012, President Barack Obama signed an Executive Order (EO) entitled “Promoting International Regulatory Cooperation,” which is intended to ensure that differing regulatory approaches taken by foreign governments do not unnecessarily limit the ability of American businesses to export and compete internationally. EO 13563, which Obama signed on January 18, 2011, states that the U.S. regulatory system must protect public health, welfare, safety, and the environment while promoting economic growth, innovation, competitiveness, and job creation. The May 1, 2012, EO calls for the Regulatory Working Group established by Executive Order 12866, and reaffirmed by EO 13563, to serve as a forum to discuss, coordinate, and develop a common understanding among agencies of U.S. government positions and priorities with respect to: international regulatory cooperation activities that are reasonably anticipated to lead to significant regulatory actions; efforts across the federal government to support significant, cross-cutting international regulatory cooperation activities; and promotion of good regulatory practices internationally, as well as the promotion of U.S. regulatory approaches, as appropriate.

Bill to Provide Tax Credits for Renewable Chemicals Introduced in the House

Representatives Bill Pascrell, Jr. (D-NJ) and Brian Bilbray (R-CA) introduced on April 26, 2012, the Qualifying Renewable Chemical Production Tax Credit Act of 2012 (H.R. 4953), which would amend the Internal Revenue Code to provide a credit for the production of renewable chemicals. The credit would be equal to $0.15 per pound of eligible content of renewable chemical produced during the taxable year. Eligible content would mean the biobased content percentage of the total mass of organic carbon in such chemical. Renewable chemical would mean any chemical produced in the U.S. from renewable biomass that is sold or used for the production of polymers, plastics, or formulated products, or as polymers, plastics, or formulated products, and is not sold or used for the production of any food, feed, or fuel. Chemicals would be excluded if the biobased content percentage is less than 25 percent; 10,000,000 pounds or more of such chemical was produced in 2000 from renewable biomass; the chemical is neither the product of nor reliant upon, biological conversion, thermal conversion, or a combination of biological and thermal conversion, of renewable biomass; or the chemical is composed of renewable chemicals that are eligible for a credit under the bill. The total number of credits under the program would be limited to $500,000,000, and no taxpayer may receive more than $25,000,000 in any taxable year. The program would end five years after the date of enactment of the bill. The bill was referred to the House Committee on Ways and Means.

ECHA Announces Updated Guidance for Registering Nanomaterials

On April 30, 2012, the European Chemicals Agency (ECHA) announced the availability of three appendices, updating Chapters R.7a, R.7b, and R.7c of the Guidance on Information Requirements and Chemical Safety Assessment (IR & CSA). ECHA prepared a draft revision of the Guidance, based on the outcome of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Implementation Projects on Nanomaterials (RIP-oN) 2 final report. ECHA updated the Guidance via a fast-track procedure, and states that this was justified on the basis that the final RIP-oN 2 report had already been the subject of consultation with relevant stakeholders. Its content could, therefore, be considered as reflecting a consensus. Furthermore, according to ECHA, the update “needed to be made urgently in order to allow publication of the guidance as soon as possible and well in advance of the next REACH registration deadline,” May 30, 2013. The updated Guidance provides tailored advice to prepare registrations for substances in the nanoform.
