Three tests were performed on the VE South stack. Table 2-1 provides a summary of the HFPO
Dimer Acid emission 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 thevarious 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 on Table 2-1 and in this report include a percentage of each of the threecompounds.

4.1 VE SOUTH STACK
Two 6-inch ID test ports are installed on the 42-inch ID steel stack. The ports are placed 150
inches (3.6 diameters) from the location where the waste gas scrubber vent enters the stack and
20 feet (5.7 diameters) from the stack exit.
Per EPA Method 1, a total of 24 traverse points (12 per axis) were used for M0010 isokinetic
sampling. It should be noted that near the port locations are a number of small ducts leading to
the stack. These are catch pots which, under normal operation, do not discharge to the stack.
They are used to vent process gas to the stack in the event of a process upset. For the purpose of
test port location, and given the fact that there is no flow from these catch pots, they are notconsidered a flow contributor or a disturbance.
See Figure 4-1 for a schematic of the test port and traverse point locations.
Note: All measurements at the test location were confirmed prior to sampling.

5. SAMPLING AND ANALYTICAL METHODS
5.1 STACK GAS SAMPLING PROCEDURES
The purpose of this section is to describe the stack gas emissions sampling train 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 wasestimated by wet bulb/dry bulb temperature measurements.
A check for the presence or absence of cyclonic flow was previously conducted at the test
location. The cyclonic flow check was negative (< 20°) verifying that the source 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 was an EPA Method0010 train (see Figure 5-1). The Method 0010 consisted of a borosilicate nozzle that attacheddirectly 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 tominimize water vapor condensation before the filter. The probe was connected directly to aheated borosilicate filter holder containing a solvent extracted glass fiber filter.

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 anda 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 thecondensate traps were maintained in an ice bath. Ice water was continuously circulated in thecondenser and the XAD-2 module to maintain method-required temperature. A control consolewith a leakless vacuum pump, a calibrated orifice, and dual inclined manometers was connectedto 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 tobe 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 andduring the sample recovery step, and was converted to HFPO Dimer Acid such that the amountof 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 wasobserved immediately after positioning the nozzle at each traverse point, and the sampling rateadjusted to maintain isokineticity at 100% ± 10. Flue gas temperature was monitored at eachpoint with a calibrated panel meter and thermocouple. Isokinetic test data was recorded at eachtraverse point during all test periods, as appropriate. Leak checks were performed on thesampling 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 thecomponents transported to the field laboratory trailer for recovery.
A consistent procedure was employed for sample recovery:

6/18/20191. The two XAD-2 covered (to minimize light degradation) sorbent modules (1 and 2) weresealed and labeled.
2. The glass fiber filter(s) were removed from the holder with tweezers and placed in apolyethylene 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 thefilter holder were rinsed with a solution of methanol and ammonium hydroxide into apolyethylene 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 withmethanol/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, filterand distilled water were retained for analysis.
Each container was labeled to clearly identify its contents. The height of the fluid level was
marked on the container of each liquid sample to provide a reference point for a leakage check
during transport. All samples were maintained cool.
During the VE South test campaign, a Method 0010 blank train was set up near the test location,leak-checked and recovered along with the respective sample train. 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, andfront-half of the filter holder solvent rinses;

Back-half Composite—comprised of the first XAD-2 resin material and the back-half ofthe filter holder with connecting glassware solvent rinses;Condensate Composite—comprised of the aqueous condensates and the contents ofimpingers one and two with solvent rinses;



Breakthrough XAD-2 Resin Tube—comprised of the resin tube behind the series ofimpingers.

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 inpolypropylene 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 wasconcentrated 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.

The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations. An integrated gas sample was collected from theexhaust of the Method 0010 sample console.
The oxygen and carbon dioxide content of the stack gas was measured according to EPA Method
3/3A procedures. 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 thestart of the test program and performance was verified by calibration checks before and after
each test run.

6/18/20196. DETAILED TEST RESULTS AND DISCUSSION
Preliminary testing and the associated analytical results required significant sample dilution tobring the HFPO Dimer Acid concentration within instrument calibration; therefore, sample times
and sample volumes were reduced for the formal test program. This was approved by the North
Carolina Department of Environmental Quality (NCDEQ).
Each test was a minimum of 96 minutes in duration. A total of three test runs were performed on
the VE South stack. During Run 3, a power outage occurred for approximately one minute andthen the test run was resumed without further incident.
Table 6-1 provides detailed test data and test results for the VE South stack.
The Method 3A sampling during all tests indicated that the O2 and CO2 concentrations were atambient air levels (20.9% O2, 0% CO2), therefore, 20.9% O2 and 0% CO2 values were used in all
calculations.
