April 17, 2006 TSCA Confidential Business Information Center (7407M) EPA East - Room 6428 Attn: FYI U.S. Environmental Protection Agency 1200 Pennsylvania Avenue, NW Washington, DC 20460-0001 RE: Supplemental Submission TSCA 8(e) FYI Notice - 0804-01378 CERTIFIED M/ 33 2D S2 mso S3 c~> a Ao Cft cn On August 3, 2005, the General Electric Company (GE) submitted a package of corroborative data on Ammonium Perfluorooctanoate (APFO) CAS# 3825-26-1, the ammonium salt of Perfluorooctanoic Acid (PFOA) CAS# 335-67-1. The data submitted on August 3, 2005 confirmed and supported data already known to the U.S. Environmental Protection Agency (the "Agency"), as embodied in numerous reports, studies, draft risk assessm ents, and related manufacturer supplied chemical information with the Agency. Since the August 3, 2005 submission, GE tested two different dry solid samples of manufactured T-SAN (Teflon-styrene acrylonitrile co-polymer), the product described under Processing Scenario 2 in the August 3, 2005 submission. Results of such testing (in parts per billion [ppb]) are provided in the following table. Resin Sample CC3YFG RD 9112 Original Test Method Result 78,000 130,000 Alternative Test Method Result 110,000 160,000 According to the laboratory chemist conducting the analysis, the Alternative Test Method results are viewed as a better representation of the sample's PFOA content. The full laboratory results report is provided as Attachment A. As provided in the August 3, 2005 submission, T-SAN is often used in small quantities in the manufacture of thermoplastic resins (or "thermoplastics"). Such thermoplastic resins may be found in a variety of end-use market segments including, but not limited to. electronics, automotive and construction. 85060000003 e oooooi As with the August 3, 2005 submission, none of the information provided in this submission represents new information, or information that would substantially change or alter the current understanding of any potential risk posed by PFOA to human health or the environment. However, given EPA's continued interest in this substance, GE is submitting this data for record completeness. Questions regarding this submission should be directed to me. Sincerely, Mark G.
