Johnson March 31, 2003 Page 20f 10 `The APFO Users are committed to reducing emissions of APFO from fluoropolymer manufacturing facilities. The APFO Users have committed to developing information to support a better understandingofexposure to APFO through conducting studies on finished resins and finished products, and on emissions and discharges from fluoropolymer processing facilities. `They are also committed to further studiesof the toxicology of APFO. Through the Society of the Plastics Industry (SP), the APFO Users will submit information on work with EPA as this process moves forward. SPI is signing this agreementonlyto signify its willingness to act as a Facilitator and conduit for information and communications between EPA and the fluoropolymer manufacturers and other membersofthe fluoropolymer industry, including fluoropolymer processors. Its participation is not an indication that SPI has any obligations addressed by separate agreements or Lettersof Intent submitted by the APFO Users, the Telomer Companies, or 3M. `The Telomer Companies do not use PFOA or APFO in their manufacturing processes. `These companies have committed to investigating whether and how telomer products can transform or break down into PFOA, andifso, to support a better understanding of those: processes. `The 3M Company has 1) provided a summaryofprevious activity taken by the company including the phase-outof the production for sale ofPFOA at the end of 2002, and 2) committed 10a plan to continue a monitoring program for its former manufacturing sites. `The APFO Users, the Telomer Companies and 3M will each keep the EPA apprised of progress in conducting the research under their respective Lettersof Intent. They will provide status reports to EPA and individually share the results from all studies, surveys or other investigations, as specified in the Letters of Intent The signatoriesofthis letter appreciate the opportunity to work with EPA on this matter and agree that close coordination ofour efforts and sharing of information is important. Accordingly, we will continue to communicate with EPA as information becomes available. Respectfully Submitted, APFO Users Telomer Companies `The 3M Company & Mr. Stephen L.
