PESTICIDES AND TOXIC SUBSTANCES Dear Interested Party: Attached is a copy in PDF file format (369 KB) of the Revised Draft Hazard Assessment O f Perfluorooctanoic Acid (PFOA) And Its Salts, prepared by the Risk Assessment Division (RAD) of the EPA Office of Pollution Prevention and Toxics (OPPT). This revision updates the original draft assessment, released in March 2002, and the minor correction issued in April 2002, to incorporate reviews of studies that were received by the Agency between July 2001 and September 2002. These studies include the two-generation reproductive study in rats that was acknowledged as ongoing in the original draft assessment, as well as a six-month monkey study and additional blood monitoring data. All of this information was submitted to AR226 as it was received. The Annex to the assessment, which contains robust summaries o f the studies reviewed in the assessment, is not attached because of its very large size (937 KB), but is available upon request as a separate file. Both files have been placed in the publicly accessible Administrative Record file AR226: PFOS, PFAS, PFOA, Telomers, and Related Chemicals. If you have any questions concerning the assessment, please contact Jennifer Seed by phone at 202-564-7634, or by email at seed.iennifer@epa.gov. If you wish to receive a copy of the Annex, or if you have any difficulties opening the files, please contact Mary Dominiak by phone at 202564-8104, by fax at 202-564-4775, or by email at dominiak.marv@.epa.gov.
