ITC Issues Priority Testing List Report

In a notice in the August 4, 2009, Federal Register, the Toxic Substances Control Act (TSCA) Interagency Testing Committee (ITC) released its latest report to the Administrator. Under TSCA Section 4(e), the ITC is required ‘‘to make recommendations to the Administrator respecting the chemical substances and mixtures to which the Administrator should give priority consideration for the promulgation of rules for testing.” According to the report, “the ITC has no revisions to the TSCA section 4(e) Priority Testing List at this time.”

The report also describes the ITC’s emphasis during the reporting period (November 2008 to May 2009) on nanoscale materials and how best to regulate them. It summarizes the ITC’s recent reviews of the U.S. Environmental Protection Agency’s (EPA) Nanoscale Materials Stewardship Program’s interim report and the National Institute for Occupational Safety and Health’s (NIOSH) nanotechnology guidelines. The report concludes by recommending data needs of ITC organizations be addressed and lists many of the data deficiencies.
