This submittal is intended to satisfy Section 2.2 D.1 j of the facility's Title V Air Permit,which requires
Chemours to submit quarterly continuous compliance reports.
Please find in Table 1 on the following page a summary of the GenX Compounds emissions for the 12-
month period ending September 30,2022.
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.
The control device operating parameters for the thermal oxidizer/scrubber system are provided under
separate cover in the quarterly Thermal Oxidizer report and control device operating parameters for the
carbon beds are provided under separate cover in the quarterly Carbon Bed report. The monitoring data is
maintained onsite and available for review upon request. If you have any questions,please contact me at

Section 2.1 B.11.k.
Prior to operation of the Thermal Oxidizer and 4-Stage Scrubber System, the Permittee shall
develop, and submit to NC DAQ for approval, a detailed shutdown and malfunction plan for the
Thermal Oxidizer and 4-stage Scrubber System that contains specific procedures for initiating
the shutdown of process emission sources during periods of control device shutdown and
malfunction, and a program of corrective action for malfunctioning processes, and control
systems used to comply with the limits in Section 2.1 B.11.a. The Permittee shall keep a copy of
the approved plan onsite.
A Shutdown and Malfunction Plan for the Thermal Oxidizer and Y
4-Stage Scrubber System was
submitted to NC DAQ on December 18,2019,which included a Proactive Maintenance Plan. The
maintenance plan includes predictive maintenance, preventive maintenance, functional checks,
corrective maintenance, and annual inspections to ensure the reliability of the Thermal Oxidizer
and 4-Stage Scrubber System.
A copy of the Shutdown and Malfunction Plan is maintained onsite and available upon request.
Section 2.1 B.H.k.i: To ensure that the control devices are well maintained to minimize
malfunctions, the plan shall include a maintenance schedule for the Thermal Oxidizer and 4-
Stage Scrubber System that is consistent with, but not limited to the manufacturer's instructions
and recommendations for routine and long-term maintenance, as specified in Section 2.1
B.11.h. and B.11,i.
A Shutdown and Malfunction Plan was submitted to NC DAQ on December 18,2019 that includes
a Proactive Maintenance Plan,which is the maintenance schedule for the Thermal Oxidizer and 4-
