Sixty-First Report of the TSCA Interagency Testing Committee to the Administrator of the Environmental Protection Agency; Receipt of Report and Request for Comments
The Toxic Substances Control Act (TSCA) Interagency Testing Committee (ITC) transmitted its 61\st\ ITC Report to the Administrator of EPA on December 18, 2007. In the 61\st\ ITC Report, which is included with this notice, the ITC is revising the TSCA section 4(e) Priority Testing List by adding 4 cresols and removing 35 High Production Volume (HPV) Challenge Program orphan chemicals. The cresols were added to obtain dermal sensitization data. To obtain dermal sensitization data, including case reports of workers and any in vivo animal sensitization test data, the ITC is asking EPA to add the 4 cresols to the TSCA section 8(d) Health and Safety Data Reporting (HaSDR) rule. The 35 HPV Challenge Program orphan chemicals are being removed from the Priority Testing List either because: Commitments were made to sponsor these chemicals under the EPA's HPV Challenge Program, the Organization for Economic Cooperation and Development (OECD) HPV Screening Information Data Set (SIDS) Program, and/or the International Council of Chemical Associations (ICCA) HPV Initiative, or because the substances were determined by EPA to be ``no longer'' HPV chemical substances.
Nanoscale Materials Stewardship Program
This document describes the design and format of EPA's Nanoscale Materials Stewardship Program (``the program'') for nanoscale materials under the Toxic Substances Control Act (TSCA). On July 12, 2007, EPA sought public comment on a concept paper that outlined its initial thinking on the design and development of the program, and several related documents. Based on ideas in the concept paper, written public comments, comments at public meetings, and scientific peer consultations on material characterization and risk management practices, EPA has developed this document to provide the final description and format of the program. EPA will consider refinements to the program over time based on experience and additional feedback from participants.
