OEHHA Revises Proposed Regulation for Hazard Traits and Environmental and Toxicological Endpoints

The Office of Environmental Health Hazard Assessment (OEHHA) announced on July 29, 2011, that it revised its proposed regulation concerning the specification of hazard traits, environmental and toxicological end-points, and other relevant data that are to be included in California’s Toxics Information Clearinghouse.  The California Department of Toxic Substances Control (DTSC) will use information from the Clearinghouse to help identify chemicals of concern in consumer products as part of its Green Chemistry Program. Comments are due September 12, 2011.

Comment Deadline Approaches for EPA's Policy on Nanoscale Materials in Pesticide Products

Comments on the U.S. Environmental Protection Agency’s (EPA) proposed policy on nanoscale materials in pesticide products are due August 17, 2011. EPA offers two approaches for obtaining the information EPA believes it needs concerning nanoscale materials in pesticide products. Under the first approach, EPA would use Section 6(a)(2) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to obtain information regarding what nanoscale material is present in a registered pesticide product and its potential effects on humans or the environment. EPA states that it would “prefer” to use this approach, despite industry’s concern over the use of the “adverse effects” reporting provision to obtain information. Under the second approach, EPA would use a data call-in (DCI) under FIFRA Section 3(c)(2)(B). EPA also proposes to apply an initial presumption that active and inert ingredients that are the nanoscale versions of non-nanoscale active and inert ingredients already present in registered pesticide products are potentially different from those conventionally sized counterparts. Registrants could rebut this initial presumption on a case-by-case basis.

EU Project Tackles Engineered Nanomaterials Risk

The European Commission (EC) announced on July 13, 2011, that European Union (EU)-funded scientists have developed risk assessment criteria for engineered nanomaterials “that will help support experts in making innovation and policy decisions.” According to the EC, findings reveal that product design can affect the unintentional release of engineered nanomaterials. The scientists suggest that the risk assessment criteria should be used to assess and minimize potential risks, which the EC states “would benefit those working in the building sector in particular, because it is estimated that nanomaterials will be used to develop 15% to 30% of facade coatings within the next 4 years.” The study is presented in the journal Environment International.

NNI Releases Reports from EHS Workshops

On July 19, 2011, the National Nanotechnology Initiative (NNI) announced the release of four reports from a series of workshops focusing on issues in the nanotechnology environmental, health, and safety (EHS) arena. According to NNI, the workshops were a part of an ongoing strategy to coordinate nanotechnology-related EHS research by convening experts from industry, academia, and the federal government to share the latest information and newest developments, to discuss the current state-of-the-science, and to identify research gaps in the nanotechnology-related EHS field. NNI states that “knowledge gleaned from the nanoEHS workshop series was critical to the development of the soon-to-be-released, updated NNI EHS Research Strategy.”

EPA Regulatory Agenda Includes Notices Concerning Nanoscale Materials

The U.S. Environmental Protection Agency’s (EPA) July 7, 2011, Regulatory Agenda includes several notices concerning nanoscale materials:

  • Test Rule for Certain Nanoscale Materials -- EPA states that it is developing a test rule under Section 4(a) of the Toxic Substances Control Act (TSCA) to require manufacturers (defined by statute to include importers) and processors of the multiwall carbon nanotube described in Premanufacture Notice (PMN) P-08-199, certain clays (e.g., kaolin (including halloysite) and bentonite (including montmorillonite)), alumina, and spray-applied nanomaterials to conduct testing for health effects, ecological effects, and environmental fate, as well as provide material characterization data. EPA intends to issue a notice of proposed rulemaking (NPRM) in August 2011.
  • Significant New Use Rule (SNUR) -- EPA is developing a SNUR for nanoscale materials under TSCA Section 5(a)(2). The SNUR would require persons who intend to manufacture, import, or process this/these chemical substance(s) for an activity that is designated as a significant new use by this proposed rule to notify EPA at least 90 days before commencing that activity. In addition, according to the notice, EPA is developing a proposal to require reporting and recordkeeping under TSCA Section 8(a), which would require that persons who manufacture these nanoscale materials notify EPA of certain information, including production volume, methods of manufacture and processing, exposure and release information, and available health and safety data. The notice regarding a TSCA Section 8(a) rulemaking was previously separate, but EPA states “those two efforts were combined into a single rulemaking.” EPA submitted a proposed rule regarding TSCA Section 8(a) reporting to the Office of Management and Budget (OMB) for review on November 22, 2010, where it remains. According to the notice, EPA intended to publish an NPRM in June 2011. Nothing has been published to date, however.

EPA Extends Comment Period on Nanoscale Materials in Pesticide Products

The U.S. Environmental Protection Agency (EPA) is expected to publish a Federal Register notice on July 13, 2011, extending the comment period concerning possible approaches for obtaining information about what nanoscale materials are present in registered pesticide products until August 17, 2011. EPA states that it received requests from CropLife America, the Biocides Panel of the American Chemistry Council, the Chemical Producers & Distributors Association, and the International Center for Technology Assessment. The NanoBusiness Commercialization Association (NanoBCA) also requested a 90-day extension of the comment period, which was not granted.

Final Recast of the RoHS Directive Published

The recast of the Directive on the Restriction of Hazardous Substances (RoHS) was published in the July 1, 2011, Official Journal of the European Union. The notice calls for the restriction of other hazardous substances and their substitution by more “environmentally friendly alternatives” as soon as scientific evidence is available, and taking into account the precautionary principle. The notice specifically states that these “other hazardous substances” include “any substances of very small size or with a very small internal or surface structure (nanomaterials) which may be hazardous due to properties relating to their size or structure.” Proposed restrictions on additional substances, including nanosilver and long multi-walled carbon nanotubes, were not supported by the European Union (EU) Council and were not included in the version of the legislation passed by both the EU Council and European Parliament (EP).

Senate Subcommittee Will Hold Hearing on Nanotechnology Investment

Today Senator John D. Rockefeller IV (D-WV), Chair of the Senate Commerce Committee, announced that the Science and Space Subcommittee will hold a hearing on July 14, 2011, at 10:00 a.m. (EDT) on national nanotechnology investment. According to Rockefeller’s July 1, 2011, press release, as the Commerce Committee considers a reauthorization of the National Nanotechnology Initiative (NNI), the hearing will examine the potential of nanotechnology, federal initiatives to coordinate research investments, barriers to commercialization, possible environmental and health risks, and steps Congress can take to improve the return on federal nanotechnology investments.
