The Chemours Company FC, LLC 910-678-1213 22828 NC Hwy 87 W Fayetteville, NC 28306-7332 VIA EMAIL January 24, 2018 Linda Culpepper Interim Director Division of Water Resources North Carolina Department of Environmental Quality RE: Receipt of Wastewater Dear Ms. Culpepper: I write on behalf of The Chemours Company FC, LLC (“Chemours”) and in response to your January 18, 2018 letter requesting information regarding the reclamation of certain materials at Chemours’ Fayetteville, North Carolina facility (“Fayetteville Works”). Your January 18th letter refers to Chemours’ reclamation of spent FRD-902 at the Fayetteville Works. This reclamation occurs entirely within the Fayetteville Works’ Polymer Processing Acid (“PPA”) area. Process wastewater from the PPA area, including wastewater generated during the reclamation of spent FRD-902, is not sent to the Fayetteville Works’ wastewater treatment plant (but instead is sent offsite for incineration). Please note that the spent FRD-902 reclaimed at the Fayetteville Works is nonhazardous under RCRA and that Chemours (and DuPont before it) has notified the U.S. Environmental Protection Agency (“EPA”) of these reclamation activities on multiple occasions. Chemours manages the reclamation of spent FRD-902 similar to how it manufactures virgin FRD-902 in the PPA area, including under the requirements of the 2009 TSCA Consent Order with EPA. Due to the scope of NCDEQ’s questions (including requests for historical information), Chemours needs additional time to respond to NCDEQ’s remaining January 18th questions. Chemours recently received a similar set of questions from EPA Linda Culpepper January 24, 2018 Page 2 with a requested due date of February 5th. Chemours proposes that it also respond to NCDEQ’s remaining questions by February 5th, at which time Chemours will also provide NCDEQ the information provided in response to EPA’s questions. Sincerely, Christel Compton Program Manager
