Re: Monthly Emissions Report Pursuant to Consent Order Paragraph 8
Dear Mr. Abraczinskas,
Pursuant to Paragraph 8.d of the Consent Order, please find enclosed the monthly
emissions report for GenX Compounds from Fayetteville Works. The report was prepared with
support from our consultant, ERM NC, Inc. (“ERM”). Please note that the spreadsheet file
underlying the report contains confidential business information of Chemours. Accordingly, we
will send that spreadsheet file under separate cover directly to you, and the spreadsheet file will
not be further distributed or posted on Chemours’ website.

Also enclosed are the final reports from Weston Solutions, Inc. (“Weston”) for the recent
emissions testing of GenX Compounds at the Polymer Processing Aid (“PPA”) and Vinyl Ethers
South (“VES”) manufacturing areas. The results from these recent testing events have been
incorporated into the calculations underlying the enclosed monthly emissions report. These
recent testing events supplement the prior emissions testing at PPA and VES performed this past
January and pursuant to the Consent Order during the first product campaigns of 2019.

The enclosed monthly emissions report shows the estimated GenX Compounds emissions
through May and the projected emissions for the rest of the year, and identifies the assumptions
that underlie the estimates, including the installation of a carbon bed at VES by the end of this
month for further control of process and indoor air (equipment) emissions. This installation
remains on track for timely completion.

Based on the identified assumptions in the enclosed monthly emissions report, ERM’s
calculations continue to show that the facility will meet the Consent Order’s 82% and 92%
requirements for plant-wide interim reductions of emissions of GenX Compounds. Should these
assumptions change, we will take other actions as necessary to maintain compliance.
