Bridget and Jamie,
Before proceeding with this interview, DWR has some research to do.
First, according to Dr. Knappe the chemical of concern is C6HF1103, CAS# 13252-13-6. However, this can and should be
verified by contacting the Lab doing the testing (Testing America?). The Lab can give the CAS# of the chemical they are
testing for soxve are all in agreement astowhat is being tested. Dr. Knappe refers tothis chemical a Perf|uoro'2'
prupuxypropanoic add, some refer to it as FRD 903 "GenX", and other states have called itC-3. [hemouru refers to it as
HFPO climer acid on occasion. If nothing else, DWR needs to be clear on what chemical is being analyzed at the lab.
Second, I believe that it was Chemours that stated DuPont had been releasing this chemical into the Cape Fear River
since the 1980s as a byproduct. Perhaps someone who attended the CFPUA meeting can confirm that statement from
Chemours. This date or statement cannot be concluded by looking at permit files that only go back to 1992.
Third, Connie and I just learned on June 301h that the HFPO climer that Michael Johnson refers to is the same thing as
FRD9O3^GenX". We have heard Michael refer to it as GenX at some points during the last couple of weeks but we were
unclear asto which GenX compound it was. Note, NPDE5 permit applications have stated that wastewater from the
HFPO monomer and the Vinyl Ethers Process are discharged to the VVVVTP but it was not stated that a byproduct in the
discharge was GenX. Again, this could be because it goes by so many different names or Chemours choose to describe it
differently —| don't know.
Fourth, I am still unclear on whether the FRD 903 GenX is used as an ingredient in the PPVE process or is a byproduct or
both. [hemours needs to explain the process and chemistry to us more clearly.
The reporters are asking good questions but we need time to research this as well.
Thanks,
Julie

Hey Bridget. Below is my email to Marla from last Thursday, modified to better reflect my current
questions. You'll see that I've made a couple of FOI requests too. The most pressing thing is the
interviews. I'm filing my story on Wednesday.
All the best,
Cathy
