2. SUMMARY OF TEST RESULTS
A total of three test runs were performed on the E2 stack. Table 2-1 provides a summary of the
HFPO Dimer Acid emissions test results. Detailed test results summaries are provided in
Section 6.
It is important to note that emphasis is being placed on the characterization of the emissions
based on the stack test results. Research conducted in developing the protocol for stack testing
HFPO Dimer Acid Fluoride, HFPO Dimer Acid Ammonium Salt and HFPO Dimer Acid
realized that the resulting testing, including collection of the air samples and extraction of the
various fraction of the sampling train, would result in all three compounds being expressed as
simply the HFPO Dimer Acid. However, it should be understood that the total HFPO Dimer
Acid results provided in Table 2-1 and in this report include a percentage of each of the three
compounds.

5. SAMPLING AND ANALYTICAL METHODS
5.1 STACK GAS SAMPLING PROCEDURES
The purpose of this section is to describe the stack gas emissions sampling trains and to provide
details of the stack sampling and analytical procedures utilized during the emissions test
program.
5.1.1 Pre-Test Determinations
Preliminary test data were obtained at the test location. Stack geometry measurements were
measured and recorded, and traverse point distances verified. A preliminary velocity traverse
was performed utilizing a calibrated S-type pitot tube and an inclined manometer to determine
velocity profiles. Flue gas temperatures were observed with a calibrated direct readout panel
meter equipped with a chromel-alumel thermocouple. Preliminary water vapor content was
estimated by wet bulb/dry bulb temperature measurements.
A check for the presence or absence of cyclonic flow was conducted at the test location. The
cyclonic flow check was negative (< 20°) verifying that the test location was acceptable for
testing.
Preliminary test data was used for nozzle sizing and sampling rate determinations for isokinetic
sampling procedures.
Calibration of probe nozzles, pitot tubes, metering systems, and temperature measurement
devices was performed as specified in Section 5 of EPA Method 5 test procedures.
5.2 STACK PARAMETERS
5.2.1 EPA Method 0010
The sampling train utilized to perform the HFPO Dimer Acid sampling at the location was an
EPA Method 0010 train (see Figure 5-1). The Method 0010 consisted of a borosilicate nozzle
that attached directly to a heated borosilicate probe. In order to minimize possible thermal
degradation of the HFPO Dimer Acid, the probe and particulate filter were heated above stack
temperature to minimize water vapor condensation before the filter. The probe was connected
directly to a heated borosilicate filter holder containing a solvent extracted glass fiber filter.

IASDATA\CHEMOURS\15418.002.018\E2 STACK REPORT 12 2019-AMD 1/21/2020 10
A section of borosilicate glass or flexible polyethylene tubing connected the filter holder exit to a
Grahm (spiral) type ice water-cooled condenser, an ice water-jacketed sorbent module containing
approximately 40 grams of XAD-2 resin. The XAD-2 resin tube was equipped with an inlet
temperature sensor. The XAD-2 resin trap was followed by a condensate knockout impinger and
a series of two impingers that contained 100 mL of high-purity distilled water. The train also
included a second XAD-2 resin trap behind the impinger section to evaluate possible sampling
train breakthrough. Each XAD-2 resin trap was connected to a 1-liter condensate knockout trap.
The final impinger contained 300 grams of dry pre-weighed silica gel. All impingers and the
condensate traps were maintained in an ice bath. Ice water was continuously circulated in the
condenser and the XAD-2 module to maintain method-required temperature. A control console
with a leakless vacuum pump, a calibrated orifice, and dual inclined manometers was connected
to the final impinger via an umbilical cord to complete the sample train.
HFPO Dimer Acid Fluoride (CAS No. 2062-98-8) that is present in the stack gas is expected to
be captured in the sampling train along with HFPO Dimer Acid (CAS No. 13252-13-6). HFPO
Dimer Acid Fluoride underwent hydrolysis instantaneously in water in the sampling train and
during the sample recovery step, and was converted to HFPO Dimer Acid such that the amount
of HFPO Dimer Acid emissions represented a combination of both HFPO Dimer Acid Fluoride
and HFPO Dimer Acid.
During sampling, gas stream velocities were measured by attaching a calibrated S-type pitot tube
into the gas stream adjacent to the sampling nozzle. The velocity pressure differential was
observed immediately after positioning the nozzle at each traverse point, and the sampling rate
adjusted to maintain isokineticity at 100% ± 10. Flue gas temperature was monitored at each
point with a calibrated panel meter and thermocouple. Isokinetic test data was recorded at each
traverse point during all test periods, as appropriate. Leak checks were performed on the
sampling apparatus according to reference method instructions, prior to and following each run,
component change (if required) or during midpoint port changes.
5.2.2 EPA Method 0010 Sample Recovery
At the conclusion of each test, the sampling train was dismantled, the openings sealed, and the
components transported to the field laboratory trailer for recovery.
A consistent procedure was employed for sample recovery:

IASDATA\CHEMOURS\15418.002.018\E2 STACK REPORT 12 2019-AMD 1/21/2020 11
1. The two XAD-2 covered (to minimize light degradation) sorbent modules (1 and 2) were
sealed and labeled.

2. The glass fiber filter(s) were removed from the holder with tweezers and placed in a
polyethylene container along with any loose particulate and filter fragments.

3. The particulate adhering to the internal surfaces of the nozzle, probe and front half of the
filter holder were rinsed with a solution of methanol and ammonium hydroxide into a
polyethylene container while brushing a minimum of three times until no visible
particulate remained. Particulate adhering to the brush was rinsed with methanol/
ammonium hydroxide into the same container. The container was sealed.

4. The volume of liquid collected in the first condensate trap was measured, the value
recorded, and the contents poured into a polyethylene container.

5. All train components between the filter exit and the first condensate trap were rinsed with
methanol/ammonium hydroxide. The solvent rinse was placed in a separate polyethylene
container and sealed.

6. The volume of liquid in impingers one and two, and the second condensate trap, were
measured, the values recorded, and the sample was placed in the same container as Step 4
above, then sealed.

7. The two impingers, condensate trap, and connectors were rinsed with methanol/
ammonium hydroxide. The solvent sample was placed in a separate polyethylene
container and sealed.

8. The silica gel in the final impinger was weighed and the weight gain value recorded.

9. Site (reagent) blank samples of the methanol/ammonium hydroxide, XAD resin, filter
and distilled water were retained for analysis.

Each container was labeled to clearly identify its contents. All samples were maintained cool.
Following sample recovery, all samples were transported to TestAmerica Laboratories, Inc.
(TestAmerica) for sample extraction and analysis.
See Figure 5-2 for a schematic of the Method 0010 sample recovery process.

5.2.3 EPA Method 0010 Sample Analysis
Method 0010 sampling trains resulted in four separate analytical fractions for HFPO Dimer Acid
analysis according to SW-846 Method 3542:
 Front-half Composite—comprised of the particulate filter, and the probe, nozzle, and
front-half of the filter holder solvent rinses;
 Back-half Composite—comprised of the first XAD-2 resin material and the back-half of
the filter holder with connecting glassware solvent rinses;
 Condensate Composite—comprised of the aqueous condensates and the contents of
impingers one and two with solvent rinses;
 Breakthrough XAD-2 Resin Tube—comprised of the resin tube behind the series of
impingers.
The second XAD-2 resin material was analyzed separately to evaluate any possible sampling
train HFPO-DA breakthrough.
The front-half and back-half composites and the second XAD-2 resin material were placed in
polypropylene wide-mouth bottles and tumbled with methanol containing 5% NH4OH for 18
hours. Portions of the extracts were processed analytically for the HFPO dimer acid by liquid
chromatography and duel mass spectroscopy (HPLC/MS/MS). The condensate composite was
concentrated onto a solid phase extraction (SPE) cartridge followed by desorption from the
cartridge using methanol. Portions of those extracts were also processed analytically by
HPLC/MS/MS.

Samples were spiked with isotope dilution internal standard (IDA) at the commencement of their
preparation to provide accurate assessments of the analytical recoveries. Final data was corrected
for IDA standard recoveries.
TestAmerica developed detailed procedures for the sample extraction and analysis for HFPO
Dimer Acid. These procedures were incorporated into the test protocol.
5.3 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations.
For the E2 stack test campaign, the sample bag was collected at the exhaust of the Method 0010
sampling system.
Each analyzer was set up and calibrated internally by introduction of calibration gas standards
directly to the analyzer from a calibration manifold. The calibration manifold is designed with an
atmospheric vent to release excess calibration gas and maintained the calibration at ambient
pressure. The direct calibration sequence consisted of alternate injections of zero and mid-range
gases with appropriate adjustments until the desired responses were obtained. The high-range
standards were then introduced in sequence without further adjustment.
The oxygen and carbon dioxide content of the stack gas was measured according to EPA Method
3A procedures which incorporate the latest updates of EPA Method 7E. A Servomex Model
4900 analyzer (or equivalent) was used to measure oxygen content. A Servomex Model 4900
analyzer (or equivalent) was used to measure carbon dioxide content of the stack gas. Both
analyzers were calibrated with EPA Protocol gases prior to the start of the test program.

6. DETAILED TEST RESULTS AND DISCUSSION
Each test was a minimum of 96 minutes in duration. A total of three test runs were performed at
the test location.
Table 6-1 provides detailed test data and test results for E2 stack.
The Method 3/3A sampling indicated that the O2 and CO2 concentrations were at ambient air
levels (20.9% O2, 0% CO2), therefore, 20.9% O2 and 0% CO2 values were used in all
calculations.
