Sheila — want me to forward the below to Sec. Cohen or do you have another message to send her?
I. What are the uses ofNsfion?
The Chemours facility provided the following description in their wastewater discharge permit application:
"The[hemouo Company -- Fayetteville Works' F|uoromonomeo/ NaOonO Membrane
manufacturing area produces several final products. ChemoursTK4 NafionO Membrane is plastic
film used inthe ch|uona|ka|i industry and inelectrochemical fuel cells. ChemoursTM NafiunO
Polymer Dispersions are used in the fabrication of thin films and coating formulations for fuel
cells membranes, catalyst coatings, sensors, and avariety ofelectrochemical applications.
The HFPO monomer and the Vinyl Ether monomers are used to manufacture various fluorochemical products such as
[hemoursTMTeOon�"
3. What can you tell us about the two Nafion byproducts: what are their chemical names and molecular structur
and are they chemically similar to GenX?
The two byproducts have Chemical Abstract Numbers: 66796-30-3 and 749836-20-2. Molecular structures are:

At this time, EPA has indicated their research leads them to believe the two above chemicals are associated with the
Nafion manufacturing process.

I don't have access to the permit application to insert into questions I & 2. Can you do that for me? I can get 3
from the EPA document. Thank you.

3?

Chris has the pen onthe press release. Attached isastart unthe Q\for review that mostly speaks to
the health side (and lack ofscientific info).
Below are some additional questions dhat|vvou|dsu88estw/eputtogetheransvver for before the press
release goes out (thanks to mark for brainstorming these — there are likely others we may want to add)
1. What are the uses of Nafion?
2. Do we know how long Chemours or it's predecessor, Dupont, has been manufacturing Nafion?
3. What can you tell us about the two Nafion byproducts: what are their chemical names and molecular
structure, and are they chemically similar toGenX?
4.Did DEQorDHH8ask the EPA to analyze the water samples for these two compounds? |fnot, why
did the EPA toss these two chemical compounds into their report?
I like our question 4 in the Q&A sent out by Jamie yesterday afternoon.
5. When did Nafion byproduct 1 or 2 appear on the radar screen for either DEQ or DHHS? How about
the EPA?
DEQ learned that EPA was analyzing for the Nafion byproducts 1 and 2 around August 11 when EPA sent
over a document identifying the 5 compounds that they would have estimates of concentration to
present tothe state later inthe month. EPA had included the two compounds inastudy inJU15.
6. How long did DEQ give Chemours to stop discharging the Nafion byproducts into the Cape Fear
River? And what will be the State's next step if Chemours refuses to do so?
DEQ requested the company reduce or eliminate the discharge of the Nafion byproducts in a letter sent
tothe company onAugust J9,Z0l7. DE[\will explore all options available tothe agency for addressing
these new compounds.
7. Did the EPA give an estimate on how long it will take to complete any of it's next steps?
EPA expects to send a report to DEQ covering the five compounds at the two locations (Chemours and
Sweeney Treatment Plan) bythe end ofthis week. DE{lwill post the report onthe vvebshe.

EPA expects a full analysis of all compounds and all locations to take several weeks or months. The
agency focused on the compounds estimated to be present in concentrations equal to or greater than
GenX. The remaining compounds are expected tubeatmuch lower concentrations.

9. What steps have been taken by DEQ and DHHS since Monday's meeting?
DE[l requested Chemours to evaluate all measures available to reduce or eliminate the discharge of
the Nahonbyproducts.

Subject: Re: Water sampling issue
I sent some edits from our office to Jamie and Chris a little while ago. Jamie can you take the lead on
combining the various edits being sent and circulate a revised draft first thing tomorrow?
I think we should anticipate both Michael and Mandy being available tomorrow afternoon by phone for
follow upquestions ifneeded.

Thanks Mandy, we will be on the look out for Chris's email and fold in the edits we have been working
on.
FYI ... We made contact with the company this afternoon via telephone and also sent a letter. The plan
is to do a press release tomorrow, so | don't think vvewill be doing a press call or at least no one has
discussed that option with me thus far so I might be out of the loop. Jamie and Noelle?

I have asked my legislative director Andy Miller to coordinate with Brad on outreach strategy and the
goal is to do ERC / member outreach tomorrow morning around 10 am. Very high level touch points. I'll
likely follow up with a few members later in the day, but asked Andy to do the initial outreach. Lets
touch base first thing inamoncoordinating GAoutreach.

Want toconfirm that the timeline below isstill accurate. What time are you planning
the press call so|can rearrange myschedule? Best would be1pm'2pmfor me. |xviUbe
inGo|dsburroatCherry Hospital for anevent but can call in.
Also — I would like to call a couple of the Members myself after the initial touch in the
rollout plan below — so would be good to coordinate with whomever is making those
calls. I will likely call Senator Lee and Rep McGrady .... but if you think I should connect
with others, let me know.
