On December 21, 2010, the California Department of Toxic Substances Control (CDTSC) issued a data call-in (DCI) for information regarding analytical test methods, and other relevant information, from manufacturers of nano silver, nano zero valent iron, nano titanium dioxide, nano zinc oxide, nano cerium oxide, and quantum dots. According to CDTSC, Health and Safety Code Section 57018(a)(4) defines a “manufacturer” as a “person who produces a chemical in this state or imports a chemical...

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” on the list of prioritization factors that CDTSC would consider in...

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...

The California Department of Toxic Substances Control (CDTSC) has rescheduled its workshop on state and federal nanomaterial activities for September 22, 2010. CDTSC, the U.S. Environmental Protection Agency (EPA), and the University of California, Los Angeles (UCLA) are cosponsoring the workshop to discuss the results of California’s carbon nanotube (CNT) information call-in, future data call-in requests for additional nanomaterials, and federal efforts related to CNTs for...

According to the California Department of Toxic Substances Control’s (CDTSC) website, it is drafting a memorandum of understanding (MOU) with the U.S. Environmental Protection Agency (EPA) to facilitate information exchange, collaboration, and outline a working partnership on emerging chemicals, green chemistry, and materials management. Under the new MOU, EPA and CDTSC will: 1.  Establish chemical specific teams for priority chemicals of mutual interest;...

Due to California’s budget issues and resulting furlough for civil service employees, the California Department of Toxic Substances Control (CDTSC) has postponed its August 13, 2010, workshop on state and federal nanomaterial activities. CDTSC, the U.S. Environmental Protection Agency (EPA), and the University of California, Los Angeles (UCLA) are cosponsoring the workshop to discuss the results of California’s carbon nanotube (CNT) information call-in, future data call-in requests for...

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...

In a January 22, 2009, letter, the California Department of Toxic Substances Control (CDTSC) announced that it is requiring the submission of data “regarding analytical test methods, fate and transport in the environment, and other relevant information from manufacturers of carbon nanotubes” (CNT). CDTSC states that the term “manufacturers” includes persons and businesses that produce CNTs in California or import CNTs into California for sale.  According to the letter, CDTSC is using...

The California Department of Toxic Substances Control (CDTSC) will hold a symposium entitled “Nanotechnology Symposium II:  Potential Hazards of Nanomaterials in the Environment” on October 3, 2007. The draft agenda includes the following topics: ...
