Wilmington, DE 19880-0023 ~ 5~ ~ Lpielf~._ 0 7M~'~R 12 A1.1 6: 0 3 2007 ~ Dear Jim, Thank you for your time in meeting with us Februa ry 20 t ', as well as for the good discussion that ensued. Enclosed ple ase find the additional information you requested on: 1) The comprehensive, peer reviewed study commissioned by DuPont and conducted by Environ on the global fate and exposure potential from DuPont Fluorotelomer products and 2) Information on the studies that DuPont h as conducted and commissioned on the biodegradation of fluorotelomer intermediates and products. Specifically, you will find the Wildlife International invoices in Appendix I (outlined in the attached document pages 2 and 3), invoices from ENVIRON in Appendix II (outlined in the attached document page 4), and Academic Studies we have suppo rted in Appendix III pages 9, 10, and 19-41 (outlined in the attached document page 5) . As well, I have included a document in Appendix IV that reviews the information we have shared with the EPA and at various scientific meetings . Included in this Appendix is the most recent information shared at the SETAC meeting in November . If you would like any of these documents please don't hesitate to ask . As a follow up I would like to arr ange a time to discuss these items and their signific ance for future work with you at your earliest convenience . With best regards, #~l *0, f ., Henry E.
