As supplied to those industrial users, telomer-based products may contain PFOA as an impurity in trace amounts. Given the known worldwide production of telomers, the levels of PFOA that would be placed in commerce per year, based on this understanding, is expected to be relatively small. We are not sure how that amount of PFOA is formed, but this information may suggest that there is some potential for telomers to transform to PFOA. We are now trying to determine whether there are relevant routes by which telomers may, in fact, transform io PFOA and to what degree these transformations take place. An important element of this LOI is our evaluation of this question. Investigating the amount of PFOA from telomer products is made more challenging by direct inputs of PFOA from other sources into the environment and by environmental loadings from legacies attributable to widespread useof discontinued surfactants and oil- and waterrepellent chemistries.

Product Stewardshipfor Customers `The TRP members are committed to the continued safe manufacture and use of telomerbased products. The TRP acknowledges that it is equally important to continue to establish and support responsible occupational health and environmental practices in the se of telomer products. TRP member companies have in place product stewardship practices with their customers. related to the application, use and occupational exposure to telomer-based products, and have ach adopted workplace health and safety practices to minimize occupational exposure. These activities are essential parts of long-standing product stewardship programs and are ongoing. Further efforts on occupational product stewardship programs will focus on technical support and assistance to telomer-based product users (customers) to assist them in keeping their occupational safety and health programs current. Accordingly, the TRP members' product stewardship role is to provide the necessary information, assist in the understandingof the. information, and provide support to customers using telomer-based products. `The TRP has no single unified product stewardship program. As a result, the TRP member companies plan to have additional product stewardship programs in place by July 2003. `These programs willbedeveloped with reference to the Responsible Care guidelines outlined in SOCMA Management Practices/ Product Stewardship Code. Each member company will provide documented evidence for their respective programs to EPA by July 2003. In addition, the TRP believes the development and distributionof a "Safe Handling and Use" handbook would be a valuable tool for our customers. This handbook would amplify the basic information contained in MSDS to provide additional information about telomers and suggestions for overall occupational exposure reduction measures for our customers" consideration. In developing such a product, we would focus on ways to make it user friendly and practical. This TRP handbook will be developed for customer review by August 2003. Continuation ofTRP Research Activites `The TRP has had a research program underway for two years, which has focused primarily on the 8-2 Telomer Alcohol. Many of these efforts wil be producing important results in 2003. In light of EPA's expressed interest in the potential formation of PFOA from telomer-based products, the TRP is reconsidering the priority of new work on the 8-2 Telomer Alcohol. The TRP intends to complete the majority of the projects that are already underway. 3 Mr. Stephen L.

Accordingly, we will continue to communicate with EPA when important information arises. In closing, we would like to emphasize that the TRP is committed to the continued safe manufacture, processing and use of telomer chemistry. We look forward to working with EPA in the future to achieve these goals. Respectfully submitted, TRP Member Companies 7 MMra.rcShte1p4h,e2n0L0.3Johnson Page 80. signature: __A, Arr Name: MH.
