Subject: RE: Presentation at DWR
It seems to me that the GenX and other ethers we find originate from the monomer production area. HFPO,
which is one monomer Chemours is producing can form GenX (also called HFPO diner acid) in water.

Question: For the sample information discussed in the paper, what laboratory performed the tests for "GenX
compounds"?
Thanks,
Julie
FYI — met with Michael Johnson from Chemours on Monday. The GenX manufacturing area referred to as
PPA is closed loop and does not have a discharge. All process wastewaters generated in this area are shipped to
AR or OH for incineration. You had asked where they were being sent in an earlier email.

That time works for me, Julie.
I will talk about the analytical method along with results. I was aware of the letter, which is also posted on the
New Hanover government web site.
See you on Friday,
Detlef

Thanks for agreeing to come in and speak this Friday, June 16th . I have made arrangements
for a room in the Archdale Building, Room 1109, from I to 3 PM (512 N. Salisbury St.,
Raleigh).
We will have a mix of wastewater engineers, hopefully some lab techs, and upper management
personnel, about 20-22 people. If you could speak a little on the test method you used to
analyze the samples that would be great. Hoping this time works for you — please let me know.
I have reserved parking space 104 in Lot 25 for you — directions are attached.
The Deputy Director asked me to forward the letter DWR received from New Hanover — that is
attached as well.
Looking forward to seeing you on Friday.
Thanks,
Julie

Dear Ms. Ravitz,
DEQ-CFW-00049649

Thank you for your letter concerning water service from the Cape Fear Public Utilities Authority
(CFPUA). Representatives from my Department have been in contact with Chemours, the Cape
Fear Public Utilities Authority, the U.S. EPA and elected officials representing the district.
Although North Carolina is awaiting guidance from the U.S. EPA, I join you in your concern.
The Department of Environmental Quality is working diligently with all partners to ensure we
evaluate the nature, extent and potential impacts of GenX. We will also continue working with
Chemours to assess waste streams containing GenX and the potential for reducing the amount of
the chemical compound being discharged to the river while we evaluate this matter.
1, and members of my senior team stand ready to join New Hanover County, CFPUA, the City of
Wilmington, Chemours and local community leaders in a meeting next week in Wilmington. We
are committed to working with all interested stakeholders to address this potential public safety
matter swiftly and thoroughly. If I can be of further assistance, please don't hesitate to contact me
at Michael Regan((Tncdenr.gov or 919-707-8622.
