1 INTRODUCTION
11 FACILITY AND BACKGROUND INFORMATION
The Chemours Fayetteville Works (Chemours) is located in Bladen County North Carolina
approximately 10 miles south of the city of Fayetteville Chemours operating areas on the site
include the Fluoromonomers IXM and Polymers Processing Aid (PPA) manufacturing areas
Wastewater Treatment and Powerhouse
Chemours contracted Weston Solutions Inc (Weston) to perform HFPO Dimer Acid Fluoride
captured as HFPO Dimer Acid and other target compound emission testing on the Division
stack at the facility Testing was performed on 22 November and 4 December 2019 and generally
followed the ldquoEmission Test Protocolrdquo reviewed and approved by the North Carolina
Department of Environmental Quality (NCDEQ) This report provides the results from the
emission test program
12 TEST OBJECTIVES
The specific objectives for this test program were as follows
Measure the emissions concentrations and mass emissions rates of HFPO Dimer Acid Fluoride and other target compounds from the Division stack which is located in the Fluoromonomers process area
Monitor and record process and emissions control data in conjunction with the test program
Provide representative emissions data
13 TEST PROGRAM OVERVIEW
During the emissions test program the concentrations and mass emissions rates of HFPO Dimer
Acid and other target compounds were measured at the Division stack
Table 1-1 provides a summary of the test location and the parameters that were measured along

2 SUMMARY OF TEST RESULTS
A total of three MM18 and two M0010 test runs were performed on the Division stack Table 2-1
provides a summary of the HFPO Dimer Acid emissions test results associated with M0010
Table 2-2 provides a summary of the target compound emissions test results associated with
MM18 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 M0010 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 M0010 HFPO
Dimer Acid results provided in Table 2-1 and in this report include a percentage of each of the
three compounds

4 DESCRIPTION OF TEST LOCATIONS
41 DIVISION STACK
Two 6-inch ID test ports were installed on the 36-inch ID fiberglass stack as shown below The
four vents that enter the top of the stack and the one vent ~11 feet below are catch pots which
under normal process operations do not discharge to the stack They are used to vent process gas
to the stack in the event of a process upset and are not considered a flow contributor or a
disturbance
Per EPA Method 1 a total of 12 traverse points (six per axis) were used for M-0010 isokinetic
sampling Figure 4-1 provides a schematic of the test ports and traverse point locations

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 previously 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

IASDATACHEMOURS15418002018DIVISION REPORT 11 2019-AMD 1212020 11
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

54 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations A diagram of the Weston sampling system is
presented in Figure 5-4
For the Division stack test campaign the sample was collected at the exhaust of the Method
0010 sampling system At the end of the line a tee permitted the introduction of calibration gas
The sample was drawn through a heated Teflonreg sample line to the sample conditioner The
output from the sampling system was recorded electronically and one minute averages were
recorded and displayed on a data logger
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 sample line integrity was verified by performing a bias test before and after each test period
The sampling system bias test consisted of introducing the zero gas and one up-range calibration
standard in excess to the valve at the probe end when the system was sampling normally The
excess calibration gas flowed out through the probe to maintain ambient sampling system
pressure Calibration gas supply was regulated to maintain constant sampling rate and pressure
Instrument bias check response was compared to internal calibration responses to insure sample
line integrity and to calculate a bias correction factor after each run using the ratio of the
measured concentration of the bias gas certified by the calibration gas supplier
The oxygen and carbon dioxide content of each 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 and
performance was verified by sample bias checks before and after each test run

6 DETAILED TEST RESULTS AND DISCUSSION
M0010 test run number two was stopped prior to the full run time due to a process upset in the
area The run was considered complete and the sample was recovered and submitted for analysis
A total of two M0010 test runs were performed at the location A total of three MM18 test runs
were performed at the location
Table 6-1 provides detailed M0010 test data and test results for Division stack Table 6-2
provides detailed MM18 test data and test results for the Division stack
The Method 3A 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 should be noted that methylene chloride was identified in the MM18 analytical results This
detection was due to a special procedure done in the process area in which methylene chloride
was used to unplug equipment that experienced plugging during testing Methylene chloride
would not typically be detected in this process area

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
Quality Control and Data Interpretation
Unless otherwise noted all holding times and QC criteria were met and the test results shown in this report meet all applicable NELAC requirements
Method 0010Method 3542 Sampling Train Preparation
Train fractions were extracted and prepared for analysis in TestAmericarsquos Knoxville laboratory Extracts and condensate samples were forwarded to the Denver laboratory for HFPO-DA analysis All results are reported in ldquoTotal ugrdquo per sample
LCMS
Method 8321A The following samples were inadvertently spiked with a native solution of HFPO-DA rather than the isotope dilution
internal standard prior to extraction in the Knoxville Laboratory
middot DIV VEN Stack R1 FHmiddot DIV VEN Stack R1 BHmiddot DIV VEN R1 Breakthrough middot DIV VEN Stack R2 FHmiddot DIV VEN Stack R2 BHmiddot DIV VEN R2 Breakthrough
As a result these samples received a relatively small fortification of the native HFPO-DA and no labeled IDA as typically applied Upon
discovery of the processing issue the IDAs were post spiked onto the extracted samples which were then re-analyzed to acquire the
Total HFPO-DA content in the samples The spiked amount of native HFPO-DA was subsequently subtracted from the Total HFPO-DA
and the corrected concentration is reported in with the data set below
Please note that under these conditions the affected samples are not corrected for extraction losses through isotope dilution internal
standard data reduction However the HFPO-DA concentrations are accurate and useful for their intended purpose
Method 8321A The laboratory control sample (LCS) and or laboratory control sample duplicate (LCSD) for preparation batch 280-478940 and analytical batch 280-479928 recovered outside control limits for the following analytes HFPO These analytes were biased high in the LCS and were not detected in the associated samples therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The LCS (LCS 140-357061-A) for analytical batch 140-35903 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were analyzed outside of analytical holding time due to ongoing instrumentation problems Y-2972 R2 VEN DIV STACK MM18 IMPINGER 3 (140-17461-9) Y-2973 R2 VEN DIV STACK MM18 IMPINGER 4 (140-17461-10) Y-2974 R2 VEN DIV STACK MM18 IMPINGER 5 (140-17461-11) and Y-2975 R2 VEN DIV STACK MM18 IMPINGER 6 (140-17461-12)
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 89459
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature

Job Narrative140-17557-1
Receipt The samples were received on December 7 2019 at 800 AM the samples arrived in good condition properly preserved and where required on ice The temperatures of the 2 coolers at receipt time were 09ordm C and 14ordm C
GCMS VOA Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B (LCS 140-359561-A) for analytical batch 140-35964 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were diluted to bring the concentration of target analytes within the calibration range Y-2976 R3 VEN DIV STACK MM18 IMPINGER 1 (140-17557-1) Y-2977 R3 VEN DIV STACK MM18 IMPINGER 2 (140-17557-2) Y-2978 R3 VEN DIV STACK MM18 IMPINGER 3 (140-17557-3) Y-2979 R3 VEN DIV STACK MM18 IMPINGER 4 (140-17557-4) Y-2980 R3 VEN DIV STACK MM18 IMPINGER 5 (140-17557-5) and Y-2981 R3 VEN DIV STACK MM18 IMPINGER 6 (140-17557-6) Elevated reporting limits (RLs) are provided
Method 8260B The continuing calibration verification (CCV) associated with batch 140-35990 recovered above the upper control limit for Chloroethane The samples associated with this CCV were non-detects for the affected analytes therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
General Chemistry Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the
12302019Page 8 of 706103
concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 33ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The following analyte(s) recovered outside control limits but within marginal exceedance limits for the LCS associated with batch 140-35880 Trichlorofluoromethane This is not indicative of a systematic control problem because these were random marginal exceedances Qualified results have been reported

General Chemistry Total Chlorine The samples were prepared for total chlorine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX- WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards

The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature

1 INTRODUCTION
11 FACILITY AND BACKGROUND INFORMATION
The Chemours Fayetteville Works (Chemours) is located in Bladen County North Carolina
approximately 10 miles south of the city of Fayetteville Chemours operating areas on the site
include the Fluoromonomers IXM and Polymers Processing Aid (PPA) manufacturing areas
Wastewater Treatment and Powerhouse
Chemours contracted Weston Solutions Inc (Weston) to perform HFPO Dimer Acid Fluoride
captured as HFPO Dimer Acid and other target compound emission testing on the Division
stack at the facility Testing was performed on 22 November and 4 December 2019 and generally
followed the ldquoEmission Test Protocolrdquo reviewed and approved by the North Carolina
Department of Environmental Quality (NCDEQ) This report provides the results from the
emission test program
12 TEST OBJECTIVES
The specific objectives for this test program were as follows
Measure the emissions concentrations and mass emissions rates of HFPO Dimer Acid Fluoride and other target compounds from the Division stack which is located in the Fluoromonomers process area
Monitor and record process and emissions control data in conjunction with the test program
Provide representative emissions data
13 TEST PROGRAM OVERVIEW
During the emissions test program the concentrations and mass emissions rates of HFPO Dimer
Acid and other target compounds were measured at the Division stack
Table 1-1 provides a summary of the test location and the parameters that were measured along

2 SUMMARY OF TEST RESULTS
A total of three MM18 and two M0010 test runs were performed on the Division stack Table 2-1
provides a summary of the HFPO Dimer Acid emissions test results associated with M0010
Table 2-2 provides a summary of the target compound emissions test results associated with
MM18 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 M0010 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 M0010 HFPO
Dimer Acid results provided in Table 2-1 and in this report include a percentage of each of the
three compounds

4 DESCRIPTION OF TEST LOCATIONS
41 DIVISION STACK
Two 6-inch ID test ports were installed on the 36-inch ID fiberglass stack as shown below The
four vents that enter the top of the stack and the one vent ~11 feet below are catch pots which
under normal process operations do not discharge to the stack They are used to vent process gas
to the stack in the event of a process upset and are not considered a flow contributor or a
disturbance
Per EPA Method 1 a total of 12 traverse points (six per axis) were used for M-0010 isokinetic
sampling Figure 4-1 provides a schematic of the test ports and traverse point locations

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 previously 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

IASDATACHEMOURS15418002018DIVISION REPORT 11 2019-AMD 1212020 11
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

54 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations A diagram of the Weston sampling system is
presented in Figure 5-4
For the Division stack test campaign the sample was collected at the exhaust of the Method
0010 sampling system At the end of the line a tee permitted the introduction of calibration gas
The sample was drawn through a heated Teflonreg sample line to the sample conditioner The
output from the sampling system was recorded electronically and one minute averages were
recorded and displayed on a data logger
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 sample line integrity was verified by performing a bias test before and after each test period
The sampling system bias test consisted of introducing the zero gas and one up-range calibration
standard in excess to the valve at the probe end when the system was sampling normally The
excess calibration gas flowed out through the probe to maintain ambient sampling system
pressure Calibration gas supply was regulated to maintain constant sampling rate and pressure
Instrument bias check response was compared to internal calibration responses to insure sample
line integrity and to calculate a bias correction factor after each run using the ratio of the
measured concentration of the bias gas certified by the calibration gas supplier
The oxygen and carbon dioxide content of each 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 and
performance was verified by sample bias checks before and after each test run

6 DETAILED TEST RESULTS AND DISCUSSION
M0010 test run number two was stopped prior to the full run time due to a process upset in the
area The run was considered complete and the sample was recovered and submitted for analysis
A total of two M0010 test runs were performed at the location A total of three MM18 test runs
were performed at the location
Table 6-1 provides detailed M0010 test data and test results for Division stack Table 6-2
provides detailed MM18 test data and test results for the Division stack
The Method 3A 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 should be noted that methylene chloride was identified in the MM18 analytical results This
detection was due to a special procedure done in the process area in which methylene chloride
was used to unplug equipment that experienced plugging during testing Methylene chloride
would not typically be detected in this process area

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
Quality Control and Data Interpretation
Unless otherwise noted all holding times and QC criteria were met and the test results shown in this report meet all applicable NELAC requirements
Method 0010Method 3542 Sampling Train Preparation
Train fractions were extracted and prepared for analysis in TestAmericarsquos Knoxville laboratory Extracts and condensate samples were forwarded to the Denver laboratory for HFPO-DA analysis All results are reported in ldquoTotal ugrdquo per sample
LCMS
Method 8321A The following samples were inadvertently spiked with a native solution of HFPO-DA rather than the isotope dilution
internal standard prior to extraction in the Knoxville Laboratory
middot DIV VEN Stack R1 FHmiddot DIV VEN Stack R1 BHmiddot DIV VEN R1 Breakthrough middot DIV VEN Stack R2 FHmiddot DIV VEN Stack R2 BHmiddot DIV VEN R2 Breakthrough
As a result these samples received a relatively small fortification of the native HFPO-DA and no labeled IDA as typically applied Upon
discovery of the processing issue the IDAs were post spiked onto the extracted samples which were then re-analyzed to acquire the
Total HFPO-DA content in the samples The spiked amount of native HFPO-DA was subsequently subtracted from the Total HFPO-DA
and the corrected concentration is reported in with the data set below
Please note that under these conditions the affected samples are not corrected for extraction losses through isotope dilution internal
standard data reduction However the HFPO-DA concentrations are accurate and useful for their intended purpose
Method 8321A The laboratory control sample (LCS) and or laboratory control sample duplicate (LCSD) for preparation batch 280-478940 and analytical batch 280-479928 recovered outside control limits for the following analytes HFPO These analytes were biased high in the LCS and were not detected in the associated samples therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The LCS (LCS 140-357061-A) for analytical batch 140-35903 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were analyzed outside of analytical holding time due to ongoing instrumentation problems Y-2972 R2 VEN DIV STACK MM18 IMPINGER 3 (140-17461-9) Y-2973 R2 VEN DIV STACK MM18 IMPINGER 4 (140-17461-10) Y-2974 R2 VEN DIV STACK MM18 IMPINGER 5 (140-17461-11) and Y-2975 R2 VEN DIV STACK MM18 IMPINGER 6 (140-17461-12)
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 89459
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature

Job Narrative140-17557-1
Receipt The samples were received on December 7 2019 at 800 AM the samples arrived in good condition properly preserved and where required on ice The temperatures of the 2 coolers at receipt time were 09ordm C and 14ordm C
GCMS VOA Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B (LCS 140-359561-A) for analytical batch 140-35964 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were diluted to bring the concentration of target analytes within the calibration range Y-2976 R3 VEN DIV STACK MM18 IMPINGER 1 (140-17557-1) Y-2977 R3 VEN DIV STACK MM18 IMPINGER 2 (140-17557-2) Y-2978 R3 VEN DIV STACK MM18 IMPINGER 3 (140-17557-3) Y-2979 R3 VEN DIV STACK MM18 IMPINGER 4 (140-17557-4) Y-2980 R3 VEN DIV STACK MM18 IMPINGER 5 (140-17557-5) and Y-2981 R3 VEN DIV STACK MM18 IMPINGER 6 (140-17557-6) Elevated reporting limits (RLs) are provided
Method 8260B The continuing calibration verification (CCV) associated with batch 140-35990 recovered above the upper control limit for Chloroethane The samples associated with this CCV were non-detects for the affected analytes therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
General Chemistry Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the
12302019Page 8 of 706103
concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 33ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The following analyte(s) recovered outside control limits but within marginal exceedance limits for the LCS associated with batch 140-35880 Trichlorofluoromethane This is not indicative of a systematic control problem because these were random marginal exceedances Qualified results have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
LCMS No analytical or quality issues were noted other than those described in the DefinitionsGlossary page
General Chemistry Total Chlorine The samples were prepared for total chlorine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX- WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 820132
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Organic Prep No analytical or quality issues were noted other than those described in the DefinitionsGlossary page

1 INTRODUCTION
11 FACILITY AND BACKGROUND INFORMATION
The Chemours Fayetteville Works (Chemours) is located in Bladen County North Carolina
approximately 10 miles south of the city of Fayetteville Chemours operating areas on the site
include the Fluoromonomers IXM and Polymers Processing Aid (PPA) manufacturing areas
Wastewater Treatment and Powerhouse
Chemours contracted Weston Solutions Inc (Weston) to perform HFPO Dimer Acid Fluoride
captured as HFPO Dimer Acid and other target compound emission testing on the Division
stack at the facility Testing was performed on 22 November and 4 December 2019 and generally
followed the ldquoEmission Test Protocolrdquo reviewed and approved by the North Carolina
Department of Environmental Quality (NCDEQ) This report provides the results from the
emission test program
12 TEST OBJECTIVES
The specific objectives for this test program were as follows
Measure the emissions concentrations and mass emissions rates of HFPO Dimer Acid Fluoride and other target compounds from the Division stack which is located in the Fluoromonomers process area
Monitor and record process and emissions control data in conjunction with the test program
Provide representative emissions data
13 TEST PROGRAM OVERVIEW
During the emissions test program the concentrations and mass emissions rates of HFPO Dimer
Acid and other target compounds were measured at the Division stack
Table 1-1 provides a summary of the test location and the parameters that were measured along
with the samplinganalytical procedures that were followed

2 SUMMARY OF TEST RESULTS
A total of three MM18 and two M0010 test runs were performed on the Division stack Table 2-1
provides a summary of the HFPO Dimer Acid emissions test results associated with M0010
Table 2-2 provides a summary of the target compound emissions test results associated with
MM18 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 M0010 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 M0010 HFPO
Dimer Acid results provided in Table 2-1 and in this report include a percentage of each of the
three compounds

41 DIVISION STACK
Two 6-inch ID test ports were installed on the 36-inch ID fiberglass stack as shown below The
four vents that enter the top of the stack and the one vent ~11 feet below are catch pots which
under normal process operations do not discharge to the stack They are used to vent process gas
to the stack in the event of a process upset and are not considered a flow contributor or a
disturbance
Per EPA Method 1 a total of 12 traverse points (six per axis) were used for M-0010 isokinetic
sampling Figure 4-1 provides a schematic of the test ports and traverse point locations

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 previously 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
18

IASDATACHEMOURS15418002018DIVISION REPORT 11 2019-AMD 1212020 11
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
IASDATACHEMOURS15418002018DIVISION REPORT 11 2019-AMD 1212020 12
1 The two XAD-2 covered (to minimize light degradation) sorbent modules (1 and 2) weresealed and labeled
2 The glass fiber filter(s) were removed from the holder with tweezers and placed in apolyethylene container along with any loose particulate and filter fragments

54 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations A diagram of the Weston sampling system is
presented in Figure 5-4
For the Division stack test campaign the sample was collected at the exhaust of the Method
0010 sampling system At the end of the line a tee permitted the introduction of calibration gas
The sample was drawn through a heated Teflonreg sample line to the sample conditioner The
output from the sampling system was recorded electronically and one minute averages were
recorded and displayed on a data logger
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 sample line integrity was verified by performing a bias test before and after each test period
The sampling system bias test consisted of introducing the zero gas and one up-range calibration
standard in excess to the valve at the probe end when the system was sampling normally The
excess calibration gas flowed out through the probe to maintain ambient sampling system
pressure Calibration gas supply was regulated to maintain constant sampling rate and pressure
Instrument bias check response was compared to internal calibration responses to insure sample
line integrity and to calculate a bias correction factor after each run using the ratio of the
measured concentration of the bias gas certified by the calibration gas supplier
The oxygen and carbon dioxide content of each 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 and
performance was verified by sample bias checks before and after each test run

6 DETAILED TEST RESULTS AND DISCUSSION
M0010 test run number two was stopped prior to the full run time due to a process upset in the
area The run was considered complete and the sample was recovered and submitted for analysis
A total of two M0010 test runs were performed at the location A total of three MM18 test runs
were performed at the location
Table 6-1 provides detailed M0010 test data and test results for Division stack Table 6-2
provides detailed MM18 test data and test results for the Division stack
The Method 3A 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 should be noted that methylene chloride was identified in the MM18 analytical results This
detection was due to a special procedure done in the process area in which methylene chloride
was used to unplug equipment that experienced plugging during testing Methylene chloride
would not typically be detected in this process area

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
Quality Control and Data Interpretation
Unless otherwise noted all holding times and QC criteria were met and the test results shown in this report meet all applicable NELAC requirements
Method 0010Method 3542 Sampling Train Preparation
Train fractions were extracted and prepared for analysis in TestAmericarsquos Knoxville laboratory Extracts and condensate samples were forwarded to the Denver laboratory for HFPO-DA analysis All results are reported in ldquoTotal ugrdquo per sample
LCMS
Method 8321A The following samples were inadvertently spiked with a native solution of HFPO-DA rather than the isotope dilution
internal standard prior to extraction in the Knoxville Laboratory
middot DIV VEN Stack R1 FHmiddot DIV VEN Stack R1 BHmiddot DIV VEN R1 Breakthrough middot DIV VEN Stack R2 FHmiddot DIV VEN Stack R2 BHmiddot DIV VEN R2 Breakthrough
As a result these samples received a relatively small fortification of the native HFPO-DA and no labeled IDA as typically applied Upon
discovery of the processing issue the IDAs were post spiked onto the extracted samples which were then re-analyzed to acquire the
Total HFPO-DA content in the samples The spiked amount of native HFPO-DA was subsequently subtracted from the Total HFPO-DA
and the corrected concentration is reported in with the data set below
Please note that under these conditions the affected samples are not corrected for extraction losses through isotope dilution internal
standard data reduction However the HFPO-DA concentrations are accurate and useful for their intended purpose
Method 8321A The laboratory control sample (LCS) and or laboratory control sample duplicate (LCSD) for preparation batch 280-478940 and analytical batch 280-479928 recovered outside control limits for the following analytes HFPO These analytes were biased high in the LCS and were not detected in the associated samples therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The LCS (LCS 140-357061-A) for analytical batch 140-35903 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were analyzed outside of analytical holding time due to ongoing instrumentation problems Y-2972 R2 VEN DIV STACK MM18 IMPINGER 3 (140-17461-9) Y-2973 R2 VEN DIV STACK MM18 IMPINGER 4 (140-17461-10) Y-2974 R2 VEN DIV STACK MM18 IMPINGER 5 (140-17461-11) and Y-2975 R2 VEN DIV STACK MM18 IMPINGER 6 (140-17461-12)
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 89459
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature

Job Narrative140-17557-1
Receipt The samples were received on December 7 2019 at 800 AM the samples arrived in good condition properly preserved and where required on ice The temperatures of the 2 coolers at receipt time were 09ordm C and 14ordm C
GCMS VOA Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B (LCS 140-359561-A) for analytical batch 140-35964 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were diluted to bring the concentration of target analytes within the calibration range Y-2976 R3 VEN DIV STACK MM18 IMPINGER 1 (140-17557-1) Y-2977 R3 VEN DIV STACK MM18 IMPINGER 2 (140-17557-2) Y-2978 R3 VEN DIV STACK MM18 IMPINGER 3 (140-17557-3) Y-2979 R3 VEN DIV STACK MM18 IMPINGER 4 (140-17557-4) Y-2980 R3 VEN DIV STACK MM18 IMPINGER 5 (140-17557-5) and Y-2981 R3 VEN DIV STACK MM18 IMPINGER 6 (140-17557-6) Elevated reporting limits (RLs) are provided
Method 8260B The continuing calibration verification (CCV) associated with batch 140-35990 recovered above the upper control limit for Chloroethane The samples associated with this CCV were non-detects for the affected analytes therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
General Chemistry Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the
12302019Page 8 of 706103
concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 33ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The following analyte(s) recovered outside control limits but within marginal exceedance limits for the LCS associated with batch 140-35880 Trichlorofluoromethane This is not indicative of a systematic control problem because these were random marginal exceedances Qualified results have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
LCMS No analytical or quality issues were noted other than those described in the DefinitionsGlossary page
General Chemistry Total Chlorine The samples were prepared for total chlorine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX- WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 820132
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Organic Prep No analytical or quality issues were noted other than those described in the DefinitionsGlossary page

1 INTRODUCTION
11 FACILITY AND BACKGROUND INFORMATION
The Chemours Fayetteville Works (Chemours) is located in Bladen County North Carolina
approximately 10 miles south of the city of Fayetteville Chemours operating areas on the site
include the Fluoromonomers IXM and Polymers Processing Aid (PPA) manufacturing areas
Wastewater Treatment and Powerhouse
Chemours contracted Weston Solutions Inc (Weston) to perform HFPO Dimer Acid Fluoride
captured as HFPO Dimer Acid and other target compound emission testing on the Division
stack at the facility Testing was performed on 22 November and 4 December 2019 and generally
followed the ldquoEmission Test Protocolrdquo reviewed and approved by the North Carolina
Department of Environmental Quality (NCDEQ) This report provides the results from the
emission test program
12 TEST OBJECTIVES
The specific objectives for this test program were as follows
Measure the emissions concentrations and mass emissions rates of HFPO Dimer Acid Fluoride and other target compounds from the Division stack which is located in the Fluoromonomers process area
Monitor and record process and emissions control data in conjunction with the test program
Provide representative emissions data
13 TEST PROGRAM OVERVIEW
During the emissions test program the concentrations and mass emissions rates of HFPO Dimer
Acid and other target compounds were measured at the Division stack
Table 1-1 provides a summary of the test location and the parameters that were measured along

2 SUMMARY OF TEST RESULTS
A total of three MM18 and two M0010 test runs were performed on the Division stack Table 2-1
provides a summary of the HFPO Dimer Acid emissions test results associated with M0010
Table 2-2 provides a summary of the target compound emissions test results associated with
MM18 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 M0010 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 M0010 HFPO
Dimer Acid results provided in Table 2-1 and in this report include a percentage of each of the
three compounds

4 DESCRIPTION OF TEST LOCATIONS
41 DIVISION STACK
Two 6-inch ID test ports were installed on the 36-inch ID fiberglass stack as shown below The
four vents that enter the top of the stack and the one vent ~11 feet below are catch pots which
under normal process operations do not discharge to the stack They are used to vent process gas
to the stack in the event of a process upset and are not considered a flow contributor or a
disturbance
Per EPA Method 1 a total of 12 traverse points (six per axis) were used for M-0010 isokinetic
sampling Figure 4-1 provides a schematic of the test ports and traverse point locations

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 previously 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

IASDATACHEMOURS15418002018DIVISION REPORT 11 2019-AMD 1212020 11
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

54 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations A diagram of the Weston sampling system is
presented in Figure 5-4
For the Division stack test campaign the sample was collected at the exhaust of the Method
0010 sampling system At the end of the line a tee permitted the introduction of calibration gas
The sample was drawn through a heated Teflonreg sample line to the sample conditioner The
output from the sampling system was recorded electronically and one minute averages were
recorded and displayed on a data logger
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 sample line integrity was verified by performing a bias test before and after each test period
The sampling system bias test consisted of introducing the zero gas and one up-range calibration
standard in excess to the valve at the probe end when the system was sampling normally The
excess calibration gas flowed out through the probe to maintain ambient sampling system
pressure Calibration gas supply was regulated to maintain constant sampling rate and pressure
Instrument bias check response was compared to internal calibration responses to insure sample
line integrity and to calculate a bias correction factor after each run using the ratio of the
measured concentration of the bias gas certified by the calibration gas supplier
The oxygen and carbon dioxide content of each 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 and
performance was verified by sample bias checks before and after each test run

6 DETAILED TEST RESULTS AND DISCUSSION
M0010 test run number two was stopped prior to the full run time due to a process upset in the
area The run was considered complete and the sample was recovered and submitted for analysis
A total of two M0010 test runs were performed at the location A total of three MM18 test runs
were performed at the location
Table 6-1 provides detailed M0010 test data and test results for Division stack Table 6-2
provides detailed MM18 test data and test results for the Division stack
The Method 3A 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 should be noted that methylene chloride was identified in the MM18 analytical results This
detection was due to a special procedure done in the process area in which methylene chloride
was used to unplug equipment that experienced plugging during testing Methylene chloride
would not typically be detected in this process area

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
Quality Control and Data Interpretation
Unless otherwise noted all holding times and QC criteria were met and the test results shown in this report meet all applicable NELAC requirements
Method 0010Method 3542 Sampling Train Preparation
Train fractions were extracted and prepared for analysis in TestAmericarsquos Knoxville laboratory Extracts and condensate samples were forwarded to the Denver laboratory for HFPO-DA analysis All results are reported in ldquoTotal ugrdquo per sample
LCMS
Method 8321A The following samples were inadvertently spiked with a native solution of HFPO-DA rather than the isotope dilution
internal standard prior to extraction in the Knoxville Laboratory
middot DIV VEN Stack R1 FHmiddot DIV VEN Stack R1 BHmiddot DIV VEN R1 Breakthrough middot DIV VEN Stack R2 FHmiddot DIV VEN Stack R2 BHmiddot DIV VEN R2 Breakthrough
As a result these samples received a relatively small fortification of the native HFPO-DA and no labeled IDA as typically applied Upon
discovery of the processing issue the IDAs were post spiked onto the extracted samples which were then re-analyzed to acquire the
Total HFPO-DA content in the samples The spiked amount of native HFPO-DA was subsequently subtracted from the Total HFPO-DA
and the corrected concentration is reported in with the data set below
Please note that under these conditions the affected samples are not corrected for extraction losses through isotope dilution internal
standard data reduction However the HFPO-DA concentrations are accurate and useful for their intended purpose
Method 8321A The laboratory control sample (LCS) and or laboratory control sample duplicate (LCSD) for preparation batch 280-478940 and analytical batch 280-479928 recovered outside control limits for the following analytes HFPO These analytes were biased high in the LCS and were not detected in the associated samples therefore the data have been reported

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The LCS (LCS 140-357061-A) for analytical batch 140-35903 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were analyzed outside of analytical holding time due to ongoing instrumentation problems Y-2972 R2 VEN DIV STACK MM18 IMPINGER 3 (140-17461-9) Y-2973 R2 VEN DIV STACK MM18 IMPINGER 4 (140-17461-10) Y-2974 R2 VEN DIV STACK MM18 IMPINGER 5 (140-17461-11) and Y-2975 R2 VEN DIV STACK MM18 IMPINGER 6 (140-17461-12)
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards

Job Narrative140-17557-1
Receipt The samples were received on December 7 2019 at 800 AM the samples arrived in good condition properly preserved and where required on ice The temperatures of the 2 coolers at receipt time were 09ordm C and 14ordm C
GCMS VOA Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B (LCS 140-359561-A) for analytical batch 140-35964 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were diluted to bring the concentration of target analytes within the calibration range Y-2976 R3 VEN DIV STACK MM18 IMPINGER 1 (140-17557-1) Y-2977 R3 VEN DIV STACK MM18 IMPINGER 2 (140-17557-2) Y-2978 R3 VEN DIV STACK MM18 IMPINGER 3 (140-17557-3) Y-2979 R3 VEN DIV STACK MM18 IMPINGER 4 (140-17557-4) Y-2980 R3 VEN DIV STACK MM18 IMPINGER 5 (140-17557-5) and Y-2981 R3 VEN DIV STACK MM18 IMPINGER 6 (140-17557-6) Elevated reporting limits (RLs) are provided
Method 8260B The continuing calibration verification (CCV) associated with batch 140-35990 recovered above the upper control limit for Chloroethane The samples associated with this CCV were non-detects for the affected analytes therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
General Chemistry Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the
12302019Page 8 of 706103
concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 33ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The following analyte(s) recovered outside control limits but within marginal exceedance limits for the LCS associated with batch 140-35880 Trichlorofluoromethane This is not indicative of a systematic control problem because these were random marginal exceedances Qualified results have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
LCMS No analytical or quality issues were noted other than those described in the DefinitionsGlossary page
General Chemistry Total Chlorine The samples were prepared for total chlorine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX- WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 820132
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Organic Prep No analytical or quality issues were noted other than those described in the DefinitionsGlossary page

1 INTRODUCTION
11 FACILITY AND BACKGROUND INFORMATION
The Chemours Fayetteville Works (Chemours) is located in Bladen County North Carolina
approximately 10 miles south of the city of Fayetteville Chemours operating areas on the site
include the Fluoromonomers IXM and Polymers Processing Aid (PPA) manufacturing areas
Wastewater Treatment and Powerhouse
Chemours contracted Weston Solutions Inc (Weston) to perform HFPO Dimer Acid Fluoride
captured as HFPO Dimer Acid and other target compound emission testing on the Division
stack at the facility Testing was performed on 22 November and 4 December 2019 and generally
followed the ldquoEmission Test Protocolrdquo reviewed and approved by the North Carolina
Department of Environmental Quality (NCDEQ) This report provides the results from the
emission test program
12 TEST OBJECTIVES
The specific objectives for this test program were as follows
Measure the emissions concentrations and mass emissions rates of HFPO Dimer Acid Fluoride and other target compounds from the Division stack which is located in the Fluoromonomers process area
Monitor and record process and emissions control data in conjunction with the test program
Provide representative emissions data
13 TEST PROGRAM OVERVIEW
During the emissions test program the concentrations and mass emissions rates of HFPO Dimer
Acid and other target compounds were measured at the Division stack
Table 1-1 provides a summary of the test location and the parameters that were measured along

2 SUMMARY OF TEST RESULTS
A total of three MM18 and two M0010 test runs were performed on the Division stack Table 2-1
provides a summary of the HFPO Dimer Acid emissions test results associated with M0010
Table 2-2 provides a summary of the target compound emissions test results associated with
MM18 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 M0010 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 M0010 HFPO
Dimer Acid results provided in Table 2-1 and in this report include a percentage of each of the
three compounds

4 DESCRIPTION OF TEST LOCATIONS
41 DIVISION STACK
Two 6-inch ID test ports were installed on the 36-inch ID fiberglass stack as shown below The
four vents that enter the top of the stack and the one vent ~11 feet below are catch pots which
under normal process operations do not discharge to the stack They are used to vent process gas
to the stack in the event of a process upset and are not considered a flow contributor or a
disturbance
Per EPA Method 1 a total of 12 traverse points (six per axis) were used for M-0010 isokinetic
sampling Figure 4-1 provides a schematic of the test ports and traverse point locations

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 previously 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

IASDATACHEMOURS15418002018DIVISION REPORT 11 2019-AMD 1212020 11
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) weresealed and labeled
2 The glass fiber filter(s) were removed from the holder with tweezers and placed in apolyethylene container along with any loose particulate and filter fragments
3 The particulate adhering to the internal surfaces of the nozzle probe and front half of thefilter holder were rinsed with a solution of methanol and ammonium hydroxide into apolyethylene container while brushing a minimum of three times until no visibleparticulate remained Particulate adhering to the brush was rinsed with methanolammonium hydroxide into the same container The container was sealed
4 The volume of liquid collected in the first condensate trap was measured the valuerecorded and the contents poured into a polyethylene container
5 All train components between the filter exit and the first condensate trap were rinsed withmethanolammonium hydroxide The solvent rinse was placed in a separate polyethylenecontainer and sealed
6 The volume of liquid in impingers one and two and the second condensate trap weremeasured the values recorded and the sample was placed in the same container as Step 4above then sealed
7 The two impingers condensate trap and connectors were rinsed with methanolammonium hydroxide The solvent sample was placed in a separate polyethylenecontainer and sealed

54 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations A diagram of the Weston sampling system is
presented in Figure 5-4
For the Division stack test campaign the sample was collected at the exhaust of the Method
0010 sampling system At the end of the line a tee permitted the introduction of calibration gas
The sample was drawn through a heated Teflonreg sample line to the sample conditioner The
output from the sampling system was recorded electronically and one minute averages were
recorded and displayed on a data logger
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 sample line integrity was verified by performing a bias test before and after each test period
The sampling system bias test consisted of introducing the zero gas and one up-range calibration
standard in excess to the valve at the probe end when the system was sampling normally The
excess calibration gas flowed out through the probe to maintain ambient sampling system
pressure Calibration gas supply was regulated to maintain constant sampling rate and pressure
Instrument bias check response was compared to internal calibration responses to insure sample
line integrity and to calculate a bias correction factor after each run using the ratio of the
measured concentration of the bias gas certified by the calibration gas supplier
The oxygen and carbon dioxide content of each 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 and
performance was verified by sample bias checks before and after each test run

6 DETAILED TEST RESULTS AND DISCUSSION
M0010 test run number two was stopped prior to the full run time due to a process upset in the
area The run was considered complete and the sample was recovered and submitted for analysis
A total of two M0010 test runs were performed at the location A total of three MM18 test runs
were performed at the location
Table 6-1 provides detailed M0010 test data and test results for Division stack Table 6-2
provides detailed MM18 test data and test results for the Division stack
The Method 3A 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 should be noted that methylene chloride was identified in the MM18 analytical results This
detection was due to a special procedure done in the process area in which methylene chloride
was used to unplug equipment that experienced plugging during testing Methylene chloride
would not typically be detected in this process area

The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
Quality Control and Data Interpretation
Unless otherwise noted all holding times and QC criteria were met and the test results shown in this report meet all applicable NELAC requirements
Method 0010Method 3542 Sampling Train Preparation
Train fractions were extracted and prepared for analysis in TestAmericarsquos Knoxville laboratory Extracts and condensate samples were forwarded to the Denver laboratory for HFPO-DA analysis All results are reported in ldquoTotal ugrdquo per sample
LCMS
Method 8321A The following samples were inadvertently spiked with a native solution of HFPO-DA rather than the isotope dilution
internal standard prior to extraction in the Knoxville Laboratory
middot DIV VEN Stack R1 FHmiddot DIV VEN Stack R1 BHmiddot DIV VEN R1 Breakthrough middot DIV VEN Stack R2 FHmiddot DIV VEN Stack R2 BHmiddot DIV VEN R2 Breakthrough
As a result these samples received a relatively small fortification of the native HFPO-DA and no labeled IDA as typically applied Upon
discovery of the processing issue the IDAs were post spiked onto the extracted samples which were then re-analyzed to acquire the
Total HFPO-DA content in the samples The spiked amount of native HFPO-DA was subsequently subtracted from the Total HFPO-DA
and the corrected concentration is reported in with the data set below
Please note that under these conditions the affected samples are not corrected for extraction losses through isotope dilution internal
standard data reduction However the HFPO-DA concentrations are accurate and useful for their intended purpose
Method 8321A The laboratory control sample (LCS) and or laboratory control sample duplicate (LCSD) for preparation batch 280-478940 and analytical batch 280-479928 recovered outside control limits for the following analytes HFPO These analytes were biased high in the LCS and were not detected in the associated samples therefore the data have been reported

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The LCS (LCS 140-357061-A) for analytical batch 140-35903 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were analyzed outside of analytical holding time due to ongoing instrumentation problems Y-2972 R2 VEN DIV STACK MM18 IMPINGER 3 (140-17461-9) Y-2973 R2 VEN DIV STACK MM18 IMPINGER 4 (140-17461-10) Y-2974 R2 VEN DIV STACK MM18 IMPINGER 5 (140-17461-11) and Y-2975 R2 VEN DIV STACK MM18 IMPINGER 6 (140-17461-12)
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards

The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature

Job Narrative140-17557-1
Receipt The samples were received on December 7 2019 at 800 AM the samples arrived in good condition properly preserved and where required on ice The temperatures of the 2 coolers at receipt time were 09ordm C and 14ordm C
GCMS VOA Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B (LCS 140-359561-A) for analytical batch 140-35964 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were diluted to bring the concentration of target analytes within the calibration range Y-2976 R3 VEN DIV STACK MM18 IMPINGER 1 (140-17557-1) Y-2977 R3 VEN DIV STACK MM18 IMPINGER 2 (140-17557-2) Y-2978 R3 VEN DIV STACK MM18 IMPINGER 3 (140-17557-3) Y-2979 R3 VEN DIV STACK MM18 IMPINGER 4 (140-17557-4) Y-2980 R3 VEN DIV STACK MM18 IMPINGER 5 (140-17557-5) and Y-2981 R3 VEN DIV STACK MM18 IMPINGER 6 (140-17557-6) Elevated reporting limits (RLs) are provided
Method 8260B The continuing calibration verification (CCV) associated with batch 140-35990 recovered above the upper control limit for Chloroethane The samples associated with this CCV were non-detects for the affected analytes therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
General Chemistry Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the
12302019Page 8 of 706103
concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 33ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The following analyte(s) recovered outside control limits but within marginal exceedance limits for the LCS associated with batch 140-35880 Trichlorofluoromethane This is not indicative of a systematic control problem because these were random marginal exceedances Qualified results have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
LCMS No analytical or quality issues were noted other than those described in the DefinitionsGlossary page
General Chemistry Total Chlorine The samples were prepared for total chlorine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX- WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 820132
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Organic Prep No analytical or quality issues were noted other than those described in the DefinitionsGlossary page

1 INTRODUCTION
11 FACILITY AND BACKGROUND INFORMATION
The Chemours Fayetteville Works (Chemours) is located in Bladen County North Carolina
approximately 10 miles south of the city of Fayetteville Chemours operating areas on the site
include the Fluoromonomers IXM and Polymers Processing Aid (PPA) manufacturing areas
Wastewater Treatment and Powerhouse
Chemours contracted Weston Solutions Inc (Weston) to perform HFPO Dimer Acid Fluoride
captured as HFPO Dimer Acid and other target compound emission testing on the Division
stack at the facility Testing was performed on 22 November and 4 December 2019 and generally
followed the ldquoEmission Test Protocolrdquo reviewed and approved by the North Carolina
Department of Environmental Quality (NCDEQ) This report provides the results from the
emission test program
12 TEST OBJECTIVES
The specific objectives for this test program were as follows
Measure the emissions concentrations and mass emissions rates of HFPO Dimer Acid Fluoride and other target compounds from the Division stack which is located in the Fluoromonomers process area
Monitor and record process and emissions control data in conjunction with the test program
Provide representative emissions data
13 TEST PROGRAM OVERVIEW
During the emissions test program the concentrations and mass emissions rates of HFPO Dimer
Acid and other target compounds were measured at the Division stack
Table 1-1 provides a summary of the test location and the parameters that were measured along

2 SUMMARY OF TEST RESULTS
A total of three MM18 and two M0010 test runs were performed on the Division stack Table 2-1
provides a summary of the HFPO Dimer Acid emissions test results associated with M0010
Table 2-2 provides a summary of the target compound emissions test results associated with
MM18 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 M0010 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 M0010 HFPO
Dimer Acid results provided in Table 2-1 and in this report include a percentage of each of the
three compounds

4 DESCRIPTION OF TEST LOCATIONS
41 DIVISION STACK
Two 6-inch ID test ports were installed on the 36-inch ID fiberglass stack as shown below The
four vents that enter the top of the stack and the one vent ~11 feet below are catch pots which
under normal process operations do not discharge to the stack They are used to vent process gas
to the stack in the event of a process upset and are not considered a flow contributor or a
disturbance
Per EPA Method 1 a total of 12 traverse points (six per axis) were used for M-0010 isokinetic
sampling Figure 4-1 provides a schematic of the test ports and traverse point locations

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 previously 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

IASDATACHEMOURS15418002018DIVISION REPORT 11 2019-AMD 1212020 11
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) weresealed and labeled
2 The glass fiber filter(s) were removed from the holder with tweezers and placed in apolyethylene container along with any loose particulate and filter fragments
3 The particulate adhering to the internal surfaces of the nozzle probe and front half of thefilter holder were rinsed with a solution of methanol and ammonium hydroxide into apolyethylene container while brushing a minimum of three times until no visibleparticulate remained Particulate adhering to the brush was rinsed with methanolammonium hydroxide into the same container The container was sealed
4 The volume of liquid collected in the first condensate trap was measured the valuerecorded and the contents poured into a polyethylene container
5 All train components between the filter exit and the first condensate trap were rinsed withmethanolammonium hydroxide The solvent rinse was placed in a separate polyethylenecontainer and sealed
6 The volume of liquid in impingers one and two and the second condensate trap weremeasured the values recorded and the sample was placed in the same container as Step 4above then sealed
7 The two impingers condensate trap and connectors were rinsed with methanolammonium hydroxide The solvent sample was placed in a separate polyethylenecontainer 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 filterand 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 Eurofins TestAmerica
(TestAmerica) for sample extraction and analysis

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

54 GAS COMPOSITION
The Weston mobile laboratory equipped with instrumental analyzers was used to measure carbon
dioxide (CO2) and oxygen (O2) concentrations A diagram of the Weston sampling system is
presented in Figure 5-4
For the Division stack test campaign the sample was collected at the exhaust of the Method
0010 sampling system At the end of the line a tee permitted the introduction of calibration gas
The sample was drawn through a heated Teflonreg sample line to the sample conditioner The
output from the sampling system was recorded electronically and one minute averages were
recorded and displayed on a data logger
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 sample line integrity was verified by performing a bias test before and after each test period
The sampling system bias test consisted of introducing the zero gas and one up-range calibration
standard in excess to the valve at the probe end when the system was sampling normally The
excess calibration gas flowed out through the probe to maintain ambient sampling system
pressure Calibration gas supply was regulated to maintain constant sampling rate and pressure
Instrument bias check response was compared to internal calibration responses to insure sample
line integrity and to calculate a bias correction factor after each run using the ratio of the
measured concentration of the bias gas certified by the calibration gas supplier
The oxygen and carbon dioxide content of each 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 and
performance was verified by sample bias checks before and after each test run

6 DETAILED TEST RESULTS AND DISCUSSION
M0010 test run number two was stopped prior to the full run time due to a process upset in the
area The run was considered complete and the sample was recovered and submitted for analysis
A total of two M0010 test runs were performed at the location A total of three MM18 test runs
were performed at the location
Table 6-1 provides detailed M0010 test data and test results for Division stack Table 6-2
provides detailed MM18 test data and test results for the Division stack
The Method 3A 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 should be noted that methylene chloride was identified in the MM18 analytical results This
detection was due to a special procedure done in the process area in which methylene chloride
was used to unplug equipment that experienced plugging during testing Methylene chloride
would not typically be detected in this process area

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
Quality Control and Data Interpretation
Unless otherwise noted all holding times and QC criteria were met and the test results shown in this report meet all applicable NELAC requirements
Method 0010Method 3542 Sampling Train Preparation
Train fractions were extracted and prepared for analysis in TestAmericarsquos Knoxville laboratory Extracts and condensate samples were forwarded to the Denver laboratory for HFPO-DA analysis All results are reported in ldquoTotal ugrdquo per sample
LCMS
Method 8321A The following samples were inadvertently spiked with a native solution of HFPO-DA rather than the isotope dilution
internal standard prior to extraction in the Knoxville Laboratory
middot DIV VEN Stack R1 FHmiddot DIV VEN Stack R1 BHmiddot DIV VEN R1 Breakthrough middot DIV VEN Stack R2 FHmiddot DIV VEN Stack R2 BHmiddot DIV VEN R2 Breakthrough
As a result these samples received a relatively small fortification of the native HFPO-DA and no labeled IDA as typically applied Upon
discovery of the processing issue the IDAs were post spiked onto the extracted samples which were then re-analyzed to acquire the
Total HFPO-DA content in the samples The spiked amount of native HFPO-DA was subsequently subtracted from the Total HFPO-DA
and the corrected concentration is reported in with the data set below
Please note that under these conditions the affected samples are not corrected for extraction losses through isotope dilution internal
standard data reduction However the HFPO-DA concentrations are accurate and useful for their intended purpose
Method 8321A The laboratory control sample (LCS) and or laboratory control sample duplicate (LCSD) for preparation batch 280-478940 and analytical batch 280-479928 recovered outside control limits for the following analytes HFPO These analytes were biased high in the LCS and were not detected in the associated samples therefore the data have been reported

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 16ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The LCS (LCS 140-357061-A) for analytical batch 140-35903 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were analyzed outside of analytical holding time due to ongoing instrumentation problems Y-2972 R2 VEN DIV STACK MM18 IMPINGER 3 (140-17461-9) Y-2973 R2 VEN DIV STACK MM18 IMPINGER 4 (140-17461-10) Y-2974 R2 VEN DIV STACK MM18 IMPINGER 5 (140-17461-11) and Y-2975 R2 VEN DIV STACK MM18 IMPINGER 6 (140-17461-12)
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards

The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature

Job Narrative140-17557-1
Receipt The samples were received on December 7 2019 at 800 AM the samples arrived in good condition properly preserved and where required on ice The temperatures of the 2 coolers at receipt time were 09ordm C and 14ordm C
GCMS VOA Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B (LCS 140-359561-A) for analytical batch 140-35964 recovered below marginal exceedance limits for Trichlorofluoromethane This is an ongoing instrument issue with LCS recoveries for this analyte The project manager approved moving forward with analysis for the current job
Method 8260B The following samples were diluted to bring the concentration of target analytes within the calibration range Y-2976 R3 VEN DIV STACK MM18 IMPINGER 1 (140-17557-1) Y-2977 R3 VEN DIV STACK MM18 IMPINGER 2 (140-17557-2) Y-2978 R3 VEN DIV STACK MM18 IMPINGER 3 (140-17557-3) Y-2979 R3 VEN DIV STACK MM18 IMPINGER 4 (140-17557-4) Y-2980 R3 VEN DIV STACK MM18 IMPINGER 5 (140-17557-5) and Y-2981 R3 VEN DIV STACK MM18 IMPINGER 6 (140-17557-6) Elevated reporting limits (RLs) are provided
Method 8260B The continuing calibration verification (CCV) associated with batch 140-35990 recovered above the upper control limit for Chloroethane The samples associated with this CCV were non-detects for the affected analytes therefore the data have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
General Chemistry Total Halogens The samples were prepared for total fluorine chlorine bromine andor iodine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX-WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the
12302019Page 8 of 706103
concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page

Sample Receipt
The samples were received on November 25 2019 at 800 AM in good condition and properly preserved The temperature of the cooler at receipt was 33ordm C
GCMS VOA
Impinger Sample Preparation and Analysis Impinger samples were analyzed for the volatile organic target analytes by purge and trap GCMS using Eurofins TestAmerica Knoxville standard operating procedure KNOX-MS-0015 based on the following method
middot SW-846 8260B ldquoVolatile Organic Compounds by Gas Chromatography Mass Spectrometry (GCMS)rdquo
Each sample is prepared by adding a known amount of sample to the purge water in a purge and trap vessel and spiking with internal standards surrogates and matrix spike analytes (as needed) Volatile compounds are introduced into the gas chromatograph by the purge and trap method The components are separated using the chromatograph and detected using a mass spectrometer which provides both qualitative and quantitative information
Impinger sample results were calculated using the following equation
Concentration μgsample = (C times DF times W times Vt) (Va)WhereC = On-column concentration μgLDF = Dilution factorW = Volume of water purged LVt = Methanol extract final volume μL Va = Volume of extract analyzed microL
Method 8260B The following analyte(s) recovered outside control limits but within marginal exceedance limits for the LCS associated with batch 140-35880 Trichlorofluoromethane This is not indicative of a systematic control problem because these were random marginal exceedances Qualified results have been reported
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
LCMS No analytical or quality issues were noted other than those described in the DefinitionsGlossary page
General Chemistry Total Chlorine The samples were prepared for total chlorine using SOP number KNOX-WC-0016 (based on ASTM Method E442 and SW-846 Method 5050) The sample is oxidized by combustion in an oxygen flask at atmospheric pressure or a bomb containing oxygen under pressure The liberated halogen compounds are absorbed primarily as halides in a sodium carbonatesodium bicarbonate buffer solution The combustion products are collected by repeated rinsing of the combustion apparatus and analyzed by ion chromatography in accordance with SOP KNOX- WC-0005 (based on SW-846 Method 9056) The results are calculated using the following equation
C = [(Ccom times Vcom) W] times 1000 gKg
WhereC = Concentration of analyte in the sample mgKgCcom = Concentration of analyte in the combustate mgLVcom = Total volume of combustate LW = Weight of sample combusted g
Anions in Impinger Solutions Anions are is determined in accordance to SOP KNOX-WC-0005 (based on methods 3000A and 9056) The samples were diluted a minimum of 120 in ion chromatography solvent buffer solution to reduce the methanol concentration before injection Buffer concentrate was added until the pH was 10 Samples are diluted with ion chromatography eluate solution to bring the concentrations within the calibration range when necessary Higher dilutions are applied as necessary
An aliquot of prepared sample is introduced into the ion chromatograph Anions are identified based on their retention times as compared to those of known standards Quantification is accomplished by measuring the peak response and comparing it to a calibration curve generated from known standards
12232019Page 8 of 820132
The pH of all samples were tested with pH paper QC consisted of initial CCV and LCS which also serve as initial calibration duplicate analysis for every 10 samples and closing CCV A certified thermometer was used to check the ambient temperature
No additional analytical or quality issues were noted other than those described above or in the DefinitionsGlossary page
Organic Prep No analytical or quality issues were noted other than those described in the DefinitionsGlossary page
