TECHNICAL GROUP Source Test Report
Introduction
1.0 Introduction
Alliance Technical Group, LLC (Alliance) was retained by The Chemours Company (Chemours) to conduct
compliance testing at the Fayetteville Works facility in Fayetteville,North Carolina. The facility operates under Title
V Permit No. 03735T48. Source emissions testing was conducted at the inlet and outlet of the Vinyl Ethers North
(VEN) carbon bed. The testing was conducted to evaluate emissions of hexafluoro-propylene oxide-dimer acid
(BFPO-DA).
1.1 Source and Control System Descriptions
VEN is part of the fluoromonomer area at the Fayetteville facility.This area produces fluorocarbon compounds used
to produce Chemours products, such as Nafion®Krytox® and Viton®. Indoor air fugitive emissions from VEN are
vented to a carbon bed which is then vented to atmosphere through the Division Stack.Process emissions from VEN
are directed to a thermal oxidizer.
1.2 Project Team
Personnel involved in this project are identified in the following table.

Summary of Results
2.0 Summary of Results
Alliance conducted compliance testing at the Fayetteville Works facility in Fayetteville, NC on August 22, 2022.
Testing consisted of determining the emission rates of BFPO-DA at the inlet and outlet of the VEN carbon bed.
Table 2-1 provides a summary of the emission testing results. Any difference between the summary results listed in
the following table and the detailed results contained in appendices is due to rounding for presentation.

Volumetric Flow Rate 1 &2 Full Velocity Traverses
Moisture Content 4 Gravimetric Analysis
Hexafluoro-Propylene Oxide-Dimer Acid Modified Method 0010 Isokinetic Sampling
3.1 U.S.EPA Reference Test Methods 1 and 2—Sampling/Traverse Points and Volumetric Flow Rate
The sampling location and number oftraverse(sampling)points were selected in accordance with U.S.EPA Reference
Test Method 1. To determine the minimum number of traverse points,the upstream and downstream distances were
equated into equivalent diameters and compared to Figure 1-1 in U.S.EPA Reference Test Method 1.
Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the
average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement
system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K-type
thermocouple and pyrometer.
3.2 U.S.EPA Reference Test Method 4—Moisture Content
The stack gas moisture content was determined in accordance with U.S. EPA Reference Test Method 4. The gas
conditioning train consisted of a series of chilled impingers. Prior to testing,each impinger was filled with a known
quantity of water or silica gel. Each impinger was analyzed gravimetrically before and after each test run on the same
balance to determine the amount of moisture condensed.
3.3 Modified Method 0010—Hexafluoro-Propylene Oxide-Dimer Acid
HFPO-DA emissions were evaluated in accordance with Modified Method 0010.Testing followed the submitted
protocol in the execution of our onsite sampling and analysis activities.Modified Method 0010 procedure was
followed as outlined in the protocol submitted to NC Division of Air Quality.Modified Method 0010 sampling and
analysis procedures performed for this project are consistent with OTM-45,which was released by EPA in January
2021,subsequent to Chemours submittal of plans to DAQ.
The sample train consisted of a borosilicate glass nozzle attached directly to a heated borosilicate glass-lined probe.
The probe was connected directly to a heated borosilicate glass filter holder containing a solvent-extracted glass fiber
filter.In order to minimize possible thermal degradation of the BFPO-DA,the probe and particulate filter were heated
to just above stack temperature to minimize water vapor condensation before the filter. The filter holder exit was
connected to a water-cooled coil condenser followed by a water-cooled sorbent module containing approximately 40
grams of XAD-2 resin. The XAD-2 inlet temperature was monitored to ensure that the module is maintained at a
temperature below 20°C.

TECHNICAL GROUP Source Test Report
Testing Methodology
The XAD-2 resin trap was followed by a condensate knockout impinger and a series of three impingers each
containing 100-ml of high purity deionized water.The water impingers were followed by another condensate knockout
impinger equipped with a second XAD-2 resin trap to account for any sample breakthrough. The final impinger
contained approximately 250 grams of dry pre-weighed silica gel. The water impingers and condensate impingers
were submerged in an ice bath through the duration of the testing.The water in the ice bath was also used to circulate
around the coil condenser and the XAD-2 resin traps.
Exhaust gases were extracted from the sample locations isokinetically using a metering console equipped with a
vacuum pump,a calibrated orifice,oil manometer and probe/filter heat controllers.
3.4 HFPO-DA Sample Train and Equipment Preparation
Prior to conducting the field work the following procedures were conducted to prepare the field sampling glassware
and sample recovery tools.
1. Wash all glassware,brushes,and ancillary tools with low residue soap and hot water.
2. Rinse all glassware,brushes,and ancillary tools three(3)times with D.I.H2O.
3. Bake glassware (with the exception of probe liners) at 450°C for approximately 2 hours, (XAD-2 resin tube
glassware is cleaned by Eurofms/TestAmerica by this same procedure).
4. Solvent rinse three(3)times all glassware,brushes,and ancillary tools with the following sequence of solvents:
acetone,methylene chloride,hexane,and methanol.
5. Clean glassware and tools will be sealed in plastic bags or aluminum foil for transport to the sampling site.
6. Squirt bottles will be new dedicated bottles of known history and dedicated to the D.I. Water and
methanol/ammonium hydroxide(MeOH/5%NH40H) solvent contents. Squirt bottles will be labelled with the
solvent content it contains.
3.5 HFPO-DA Sample Train Recovery
Following completion of each test run,the sample probe,nozzle and front-half of the filter holder were brushed and
rinsed three times each with the McOH/5%NH40H solution(Container#1).The glass fiber filter was removed from
its housing and transferred to a polyethylene bottle (Container #2). Any particulate matter and filter fibers which
adhered to the filter holder and gasket were also placed in Container#2.The XAD-2 resin trap was sealed, labelled
and placed in an iced sample cooler.The back-half of the filter holder,coil condenser condensate trap and connecting
glassware were rinsed with the same McOH/5%NH40H solution and placed in Container#3.
The volume of water collected in all impingers was measured for moisture determinations and then placed in Container
#4. All impingers and connecting glassware were then rinsed with the McOH/5%NH40H solution and placed in
Container#5.The second(breakthrough)XAD-2 resin trap was sealed,labelled and placed in an iced sample cooler.
The contents of the fifth impinger were placed in its original container and weighed for moisture determinations.
Containers were sealed and labeled with the appropriate sample information.Samples remained chilled until analysis.
BFPO-DA analysis was conducted using liquid chromatography/dual mass spectrometry(LC/MS/MS).
