Re: July 21, 2017 North Carolina Department of Environmental Quality Letter to The
Chemours Company
Dear Ms. Culpepper:
This letter is to advise you that The Chemours Company FC, LLC ("Chemours")
received the July 21, 2017 letter from Secretary Regan regarding issues related to Chemours'
Fayetteville, NC facility, which directed us to provide the requested information to your
attention.
1 can assure you that Chemours intends to continue to cooperate with DEQ and to
respond to the requests for information in Secretary Regan's letter. To that end, we have asked
one of our outside counsel, Steve DeGeorge, in Charlotte, North Carolina, to contact DEQ
counsel, to obtain clarification of DEQ's requests and discuss a timetable for response. Mr.
DeGeorge has not yet heard back from DEQ counsel. His letter dated August 2, 2017 to DEQ's
General Counsel William Lane is attached. As you can see, that letter reaffirms Chemours'
commitment to cooperating with DEQ.
Mr. DeGeorge's letter indicated that Chemours would provide by today a summary of the
sampling and analysis conducted by Chemours in June and July for C3 dimer acid at its
discharge into the Cape Fear River. Specifically, please find attached a July 28, 2017 letter from
Dawn Clark (Chemours, U.S. Chemical Management Leader) to Shelia Holman (DEQ, Assistant
Secretary for the Environment) that encloses recent sampling data and a hard copy of the July
13th presentation that Chemours provided to representative's of the U.S. Environmental
Protection Agency and DEQ, including Ms. Holman and yourself. As you may be aware, DEQ
is conducting its own testing of the Cape Fear River and those results are publicly available. See
DEQ, GenX Sampling Sites, ktt ps:#Aeg.ne.gov/news/hot-topicstgcnx-investigad2n/genx-
sampling-sites. Chemours is not conducting its own sampling within the Cape Fear River.
Since we submitted the attached July 28th letter, Chemours has received analytical results
fi-oin its internal laboratory for samples collected on July 25 and 26, 2017 in the effluent channel
upstream and near outfall 002 at the Fayetteville Works and these results --like other from the
DEQ-CFW 00074646

effluent channel taken during the preceding week —show that the concentrations of 0 dimer
acid were below, the laboratory's 2ppb level of detection.
We expect to be able to provide further responsive materials promptly once our
respective counsel have been able to discuss the matter further.
We look forward to continuing to work with DE Q cooperatively on this matter.
Cc: William Lane, Esq.
Sincerely,
dA
