Submission of Quarterly Progress Report Pursuant to Consent Order Paragraph 28

Dear Ms. Holman,
Chemours is pleased to submit the enclosed fourth quarterly progress report, as required
under paragraph 28 of the Consent Order entered by the Superior Court for Bladen County onFebruary 25, 2019. This quarterly progress report details the work and activities undertaken andcompleted pursuant to the Consent Order for the period from October 1, 2019 to December 31,
2019.
Our comprehensive work to implement the projects set forth in the Consent Ordercontinues on schedule. Significant actions undertaken during this reporting period include:•Chemours successfully completed installation and startup of its new thermal oxidizer
facility on December 27, 2019. The thermal oxidizer facility represents a $100 million
investment by Chemours in emissions control technology, and positions the Fayettevilleplant as a best-in-class manufacturing facility for air emission control. Construction wasmechanically complete in November, and after routine commissioning activities and tests
for the facility, the thermal oxidizer became fully operational on December 27.
Chemours switched to the permitted operating scenario for the thermal oxidizer on
December 31. Within 90 days of installation, Chemours and the North Carolina Divisionof Air Quality will conduct testing to confirm that the thermal oxidizer is destroying
99.99% of all PFAS air emissions routed to it.

•Chemours continued to test its interim air controls, which have worked to meet therequirements of the Consent Order, including achieving a 92% reduction in air emissionsof GenX Compounds for 2019 from 2017 levels.

•All of Chemours’s process wastewater continues to be captured and safely disposed ofoff-site.

•Significant work continues to reduce the remaining PFAS loadings from surface waterand groundwater to the Cape Fear River. The remaining areas of PFAS contamination atthe Site, and associated discharges therefrom, are almost entirely the legacy of prior
operations, mostly by Chemours’s predecessor, DuPont. On November 4, 2019,
Chemours submitted a Supplemental Information Report for its August 26 Cape FearRiver PFAS Loading Reduction Plan, providing supplemental information to support theevaluation of remedial options to reduce loadings from this legacy PFAS contamination.
On December 31, 2019, Chemours submitted the Corrective Action Plan (CAP), which
describes proposed remediation activities to address legacy PFAS in groundwater andsurface waters at the Site, in accordance with the requirements of the Consent Order andthe North Carolina 2L Rules. The CAP proposes a robust set of nine corrective actions
and two interim actions that will further reduce PFAS loadings, including interim andpermanent actions that will address at least 95% of the loadings from the groundwater
seeps and at least 99% of the loadings from the Old Outfall 002 channel, which are thetwo most significant contributors of ongoing loadings of PFAS to surface waters.
•Chemours continues to conduct extensive testing and provide replacement drinking watersupplies to qualifying residences and other private well users. Nearly 1500 residences arereceiving bottled water, and whole building and under sink filtration systems arecontinuing to be installed.

We are focused and intent on ensuring that the Consent Order implementation continues
to proceed in the same manner.
As always, if you have any questions or need any additional information concerning thisreport, or the Consent Order implementation generally, please contact me at
