Comment submitted by Michael Feldstein, President, Surface Technology, Inc.

Pursuant to conversations with Ms. Amy Breedlove of the Environmental Protection Agency on Friday April 7, 2006 and Tuesday April 11, 2006, I am writing to advise that our company is using an existing stock of a surfactant which contains PFOS. Our company does not and will not manufacture PFOS. Our company does not and will not import PFOS. Our company is only using an existing stock of this surfactant that contains some PFOS as a minor but necessary ingredient in one of our products. The product in which we use a small quantity of the PFOS containing material is a water based PTFE (DuPont trade name = Teflon) dispersion used in composite electroless nickel plating. It is our understanding that, as we have an existing stock of the material containing PFOS, we are allowed to continue to use this material as a processor by including it in our product. It would be very damaging to our company and its employees if we were not able to continue to use its current stock of this PFOS containing material. We would appreciate a letter of confirmation from the Environmental Protection Agency confirming that this is an acceptable use of our existing stock of this material. Thank you.
