The Office of Environmental Health Hazard Assessment (OEHHA) has posted comments received on its July 29, 2011, revised proposed regulation concerning the specification of hazard traits, environmental and toxicological endpoints, 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

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.

Last week, the University of California, San Francisco’s (UCSF) Program on Reproductive Health and the Environment announced the publication of its “Recommendations for Addressing Potential Health Risks from Nanomaterials in California,” which provides recommendations for addressing potential health risks from nanomaterials to the Office of Environmental Health Hazard Assessment (OEHHA) and to the state of California.  OEHHA contracted with UCSF to prepare the report, which provides an overview of nanotechnology materials, potential exposures, and human-health risks, and recommendations for addressing potential health hazards and risks from nanotechnology. Recommendations include those that can be implemented under the existing regulatory structure of OEHHA, such as establishing a publicly accessible clearinghouse and inventory of nanomaterial sources and products. The report also includes recommendations that are outside the scope of OEHHA, many of which may require legislative changes, such as requiring testing of release and exposure potential for nanomaterials in existing and new consumer products, and implementing a labeling system that requires labeling of products that contain nanomaterials.  According to UCSF, the recommendations primarily focus on requiring information on potential exposures and health hazards for nanomaterials used in the marketplace.

On November 16, 2010, the California Department of Toxic Substances Control (CDTSC) released revisions to its safer consumer product alternatives regulations for a 15-day comment period. Of particular note, CDTSC has removed all references to nanotechnology and nanomaterials in the proposed regulations, which previously defined nanomaterials and included “physical, chemical, or quantum properties specific to nanomaterials&rdquo

On April 22, 2010, the California Office of Environmental Health Hazard Assessment (OEHHA) announced that, on May 5, 2010, the University of California at San Francisco’s (UCSF) Program on Reproductive Health will hear comments from an expert panel and the public on a draft UCSF document entitled “A Nanotechnology Policy Framework: Policy Recommendations for
