Re: 99% Facility-Wide Reduction of GenX Compounds Emissions Pursuant to
Consent Order Paragraph 8.c

Dear Mr. Abraczinskas,

This submittal is intended to satisfy Paragraph 8.c of the Consent Order and Section 2.2 D.1 of
the facility’s Title V Air Permit, which requires Chemours to submit a report by February 28,
2021 documenting that Facility-wide air emissions of GenX Compounds in calendar year 2020
have been reduced by at least 99% from 2017 Total Reported Emissions.

Please find in Table 1 on the following page a summary of the GenX Compounds emissions for
calendar year 2020. This table demonstrates that Chemours has met the Consent Order’s and
Title V Permit’s 99% requirement for plant-wide reductions of GenX Compounds emissions
from 2017 Total Reported Emissions. These emissions were calculated pursuant to Paragraph 8.c
of the Consent Order, which requires that Chemours submit annual emissions reports for GenX
Compounds and include fugitive, maintenance, malfunction and accidental emissions.

The spreadsheet file with the calculations underlying the GenX Compounds emissions presented
in Table 1 was prepared by our consultant, ERM NC, Inc. (“ERM”). The spreadsheet file also
provides the emissions test data, control device data, and production data underlying the
calculations, as well as notes on the calculation methodologies. Because the spreadsheet file
contains confidential business information of Chemours, 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.

If you have any questions, please contact me at [e-mail].

Sincerely,

Dawn M Hughes
Plant Manager
