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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 14

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

front-half of the filter holder solvent rinses

Back-half Compositemdashcomprised of the first XAD-2 resin material and the back-half of

the filter holder with connecting glassware solvent rinses

Condensate Compositemdashcomprised of the aqueous condensates and the contents of

impingers one and two with solvent rinses

Breakthrough XAD-2 Resin Tubemdashcomprised 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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

523 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 Compositemdashcomprised of the particulate filter and the probe nozzle and

front-half of the filter holder solvent rinses

Back-half Compositemdashcomprised of the first XAD-2 resin material and the back-half of

the filter holder with connecting glassware solvent rinses

Condensate Compositemdashcomprised of the aqueous condensates and the contents of

impingers one and two with solvent rinses

Breakthrough XAD-2 Resin Tubemdashcomprised 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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

5 SAMPLING AND ANALYTICAL METHODS

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

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 methanolammonium 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 methanolammonium 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

523 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 Compositemdashcomprised of the particulate filter and the probe nozzle and

front-half of the filter holder solvent rinses

Back-half Compositemdashcomprised of the first XAD-2 resin material and the back-half of

the filter holder with connecting glassware solvent rinses

Condensate Compositemdashcomprised of the aqueous condensates and the contents of

impingers one and two with solvent rinses

Breakthrough XAD-2 Resin Tubemdashcomprised 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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

5 SAMPLING AND ANALYTICAL METHODS

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

5 SAMPLING AND ANALYTICAL METHODS

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

5 SAMPLING AND ANALYTICAL METHODS

51 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

511 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 bulbdry 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 (lt 20deg) 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

52 STACK PARAMETERS

521 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

523 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 Compositemdashcomprised of the particulate filter and the probe nozzle and

front-half of the filter holder solvent rinses

Back-half Compositemdashcomprised of the first XAD-2 resin material and the back-half of

the filter holder with connecting glassware solvent rinses

Condensate Compositemdashcomprised of the aqueous condensates and the contents of

impingers one and two with solvent rinses

Breakthrough XAD-2 Resin Tubemdashcomprised 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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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 plusmn 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

522 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

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 methanolammonium 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 methanolammonium 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

523 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 Compositemdashcomprised of the particulate filter and the probe nozzle and

front-half of the filter holder solvent rinses

Back-half Compositemdashcomprised of the first XAD-2 resin material and the back-half of

the filter holder with connecting glassware solvent rinses

Condensate Compositemdashcomprised of the aqueous condensates and the contents of

impingers one and two with solvent rinses

Breakthrough XAD-2 Resin Tubemdashcomprised 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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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 plusmn 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

522 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

IASDATACHEMOURS15418002018E2 STACK REPORT 12 2019-AMD 1212020 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 methanolammonium 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 methanolammonium 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

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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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 methanolammonium 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 methanolammonium 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

523 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 Compositemdashcomprised of the particulate filter and the probe nozzle and

front-half of the filter holder solvent rinses

Back-half Compositemdashcomprised of the first XAD-2 resin material and the back-half of

the filter holder with connecting glassware solvent rinses

Condensate Compositemdashcomprised of the aqueous condensates and the contents of

impingers one and two with solvent rinses

Breakthrough XAD-2 Resin Tubemdashcomprised 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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

523 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 Compositemdashcomprised of the particulate filter and the probe nozzle and

front-half of the filter holder solvent rinses

Back-half Compositemdashcomprised of the first XAD-2 resin material and the back-half of

the filter holder with connecting glassware solvent rinses

Condensate Compositemdashcomprised of the aqueous condensates and the contents of

impingers one and two with solvent rinses

Breakthrough XAD-2 Resin Tubemdashcomprised 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 (HPLCMSMS) 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

HPLCMSMS

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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

53 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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations

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 33A sampling indicated that the O2 and CO2 concentrations were at ambient air

levels (209 O2 0 CO2) therefore 209 O2 and 0 CO2 values were used in all

calculations
