DAQ's Comments Regarding Inventory
arsenic,cadmium metal,chromic acid VI,cobalt,lead,manganese,mercury,nickel metal,
formaldehyde,n-hexane,hydrogen chloride,decreased due to a 97%decrease in natural gas
throughput for their natural gas-fired boiler(OS65).
Reported emissions from PM2.5,S02,is below the de minimus.
ethylene dichloride,nitric acid decreased due to the amount purchased in 2021 for the sitewide
laboratory(OS82).Acetic acid reported emissions in 2020 was the sum over a 48 month period.
CFC-113 increased due to the increase in the number of hours used to produce dimer acid peroxide
in the semiworks area.In 2020 semiworks operated for 251 hours and in 2021 it operated for 554
hours. See EI for more detail.
Fluorides increased due to a 82%increase in throughput for the nafion MMF process.

SUBJECT: 2021 Air Emissions Inventory Report
Chemours Company—Fayetteville Works
Bladen County,North Carolina
Air Permit No. 03 73 5T48
Facility ID: 0900009
Dear Ms. Carter,
Pursuant to Section 3 of the subject Title V Air Permit, enclosed are the Inventory Certification
Form and the Air Emissions Inventory Report for the Chemours Company—Fayetteville Works.
The Confidential Submissions is being submitted under separate cover.
Chemours prepared the 2021 Air Emissions Inventory Report with the assistance of ERM NC,Inc.
The methods for calculating the emissions figures(e.g.,stack testing results,engineering estimates,
emissions factors) are provided alongside the emissions figures in the Report. Further, although
the Permit does not require the quantification of VOC emissions by the specific VOC, Chemours
is voluntarily providing emissions figures for specific VOCs as it has done for prior years.
Chemours will submit updates to this Report if it determines (e.g.,through additional testing)that
any of the emissions figures provided herein have changed.
Please note that several emissions sources have been grouped. Therefore, a portion of the NS-13
emissions are associated with fugitive outdoor equipment and some are associated with indoor
equipment that is vented to the carbon bed (NCD-Q3); however, all VOCs have been captured in
the total emission values. In addition, emissions for NS-G sources were also grouped. However,
emissions for NS-G-2 are not controlled by the thermal oxidizer and the emissions are thus
reflected.
If you have any questions regarding this Report,please call me at [phone].
Sincerely,
Dawn M Hughes
Plant Manager

In July 2018, stack testing was performed on the PPA Process Stack (ID No. AEP-Al)for the
HFPO Dimer anion and was later analyzed for PFOA. The stack testing results from the tests
showed an average emission rate of 2.75E-06 Ibs/hr of PFOA.
Annual emissions are estimated by using the stack testing emission rates in Ibs PFOA per hour and
multiplying those emission rates by the hours of operation druing this period.

NCD-Q1 - Thermal Oxidizer Natural Gas Combustion
Process Description
The Thermal Oxidizer/Scrubber System is used to control emissions from existing sources at the Fayetteville
facility. The system includes a Thermal Oxidizer to control volatile organic compounds (VOC), per-fluorinated and
poly-fluorinated (PFAS)emissions. The system also includes a Caustic Scrubber which is utilized to remove
residual hydrogen fluoride vapor and other acid gases from the discharge of the Thermal Oxidizer and Liquid Mist
Separator.The Thermal Oxidizer/Scrubber System consists of two Gas Accumulation Tanks,Thermal Converter,
Liquid Mist Separator, Catch Tank, and Acid Storage Tank.
The existing emission units are vented to the Thermal Oxidizer/Scrubber System. Overall process emissions of
VOCs and HAS compounds are controlled by more than 99.99% in the Thermal Oxidizer.The Thermal Oxidizer
also generates emissions associated with the combustion of natural gas. The Thermal Oxidizer also generates HF
and CO2 emissions due to combustion of the organic hydrocarbons. SO2 is also generated in the thermal oxidizer
from the combustion of sulfur containing organic hydrocarbons.The process emissions associated with the
Thermal Oxidizer/Scrubber system are calculated separately in the individual process workbooks.This workbook
only provides the emissions associate with the combustion of natural gas and process dimer acid emissions which
utilize stack emission test results.
Emission Calculations
Emissions from the fuel combustion in the thermal oxidizer are calculated using emission factors from AP-42, 5th
Edition, Section 1.4, 7/98 except for acetaldehyde, acrolein and ammonia,these factors are from the WebFIRE
database.

The number of decontamination events required is based on the HFP consumed divided by the typical transfer amount,rounded up.
2,476,190 / 13,500 = 183.5
Total HFP from decontamination of unloading hoses=Number of events (vented from liquid hose+vapor hose+compressor+piping)
183.5 X 19.6 = 3,601 kg HFP
7,939 Ibs HFP from hose decon
HFP is also vented from the Crude Dryers each time a dryer is changed. The basis for this calculation assumes the composition of vapor
in the dryer is 50.0%HFP and 50.0%HFPO,
and the vapor density is 3.30 Ibs/ft3(reference ASPEN model)
The molecular sieves have a bulk density of 47 Ibs per ft3 of bed volume
The density of the sieves themselves is 57 Ibs per ft3 according to a recent Certificate of Analysis.
Therefore the void fraction of a bed of sieves would be 0.175 ft3 void volume per ft3 total bed volume
From BPF dimensions of the dryer,it is estimated that 10'height of 10"diameter space is filled with sieves,plus 2'of a 6"diameter section.
The remaining space at the top containing no sieves consists of 6"high x 10"diameter section plus a 8"high x 6"dia. section.
Vapor volume in dryer= 1.43 ft3 of vapor
X vapor density of 3.3 Ibs/ft3

Dryer changes occur every 48 hours. The number of dryer changes is estimated to be 151.8

3. Fugitive Emissions From Benzene
Basis: Fugitive emissions are determined via mass balance, i.e.any mass of benzene unaccounted for in the mass balance will be
assumed to be air emissions.
Assume that: Benzene introduced into the process is mostly destroyed by reaction.
Ratio of emissions to benzene used=1.9 Ibs emission/368 Ibs benzene used
Calculations:
Benzene introduced to process: 578.2 Ibs
Benzene emissions:
578.2 Ibs x 1.90 Ibs emission = 2.985 Ibs benzene emission
368 Ibs benzene
4.Fugitive Emissions of Toluene by Mass Balance
Basis: Fugitive emissions are determined via mass balance, i.e.any mass of toluene unaccounted for in the mass balance will be assumed
to be air emissions.
Assume that: 95%of raw ingredient becomes waste
Mass Balance:
Toluene inventory in process as first day of year('User Ent + 4,830 Ibs Inventory taken into account witl
Toluene added to process: + 16,694 Ibs
Toluene inventory in process as of last day of year('User E - 4,998 Ibs 1-Jan
Toluene destroyed in process: - 0.000 Ibs
Toluene shipped off with product: - 0.000 Ibs injected into product
Toluene removed from process as a solid waste: - 16451 Ibs
Toluene released to air via permitted stack: - 0.034 Ibs
Toluene released to process wastewater: - 0.000 Ibs
Toluene released to the ground(spill): - 0.000 Ibs
Unaccounted for difference in mass: = 74.5 Ibs toluene = 74 Ibs VOC

Emission Source Description: VE-North PPVE Manufacturing Process
Process&Emission Description: The VE-North PPVE manufacturing process is a continuous chemical
reaction. All emissions from the process are vented to the Thermal Oxidizer/Scrubber System(TO)
(Control Device ID No.NCD-Q1/Q2)which has a documented control efficiency of 99.99%for all VOC and
PFAS compounds.The control of emissions of specific compounds will be addressed and detailed in the
following pages.
Basis and Assumptions:
-The PPVE process flowsheet is the basis for relative concentrations of before-control emissions of
gaseous wastes.
-Calculations of point source emissions are based on actual vent flow totals taken from the IP21
Historian.

On April 5,2018 and April 25-26,2018,source testing was performed on the Division Stack while the HFPO Process unit
was operating and VE-North Process Unit was operating and producing PPVE. It was determined by review of process data
(i.e.,flow meter trends)that the source tests presented in the table below were conducted while the VE-North Stripper
Column was being vented. The results of those source tests are also included in the below table.
HFPONE-North(With Stripper Column Vent)Source Test Results

04-26-2018 Division 3 8.53
04-26-2018 Division 4 12.36
Avg Emission Rate 15.37
The source testing for the HFPO Process indicated emissions of 4.67 Ib/hr;therefore to determine VE-North's contribution,
4.67 Ib/hr was subtracted from the average emission rate shown in the above Table(15.37 Ib/hr). The resulting emission
rate,for VE-North during periods when the Stripper Column was venting,is 10.70 lb/hr.
VE North Stripper Column emission rate= 10.70 Ibs HFPO/hour
Review of VE-North process data from the data historian indicates that the VE-North Stripper Column vented for 639 hours
during 2017. The Stripper Column was assumed to be venting when the process was being fed and the manual and control
valves on the vent line were open. Review of the data also indicated that there were 460 hours during which the data
historian did not maintain the process data. To be conservative,the emission estimates in CY2017 assumed that the
Stripper Column was venting for 1,099 hours during 2017. During CY2017,VE-North produced 213,837 kg of vinyl ethers.
This ratio(1099 hours/213,837 kg=0.005 hr/kg produced)will be used to estimate hours of stripper column venting during
CY2018.
Stripper Column Venting Ratio= 0.005 hours of venting per kg produced
VE North Stripper Column venting time= 1,123 hours
VE North Stripper Column emissions= 1,123 hr X 10.70 Ibs HFPO/hour
VE North Stripper Column emissions= 12,013 Ibs HFPO
HFPO emissions would also be emitted from the VE-North Condensation Reactor on a routine,as-needed basis.HFPO
emissions from the VE-North Condensation Reactor,while producing PPVE,were determined using the total mass flow from
the Condensation Reactor vent along with the concentration of HFPO in the Condensation Reactor vent stream. Emissions
were calculated as follows:
HFPO unreacted in condensation is vented to the TO.

2021 Maintenance Emission Determination
A. Background
Periodically,the process vessels in the VE-North plant are emptied for campaign switches and for
maintenance. During the deinventory process,the liquid is transferred to another process vessel and then the
gases are evacuated to the Thermal Oxidizer/Scrubber System(TO),Control Device ID NCD-Q1/Q2,which
has a control efficiency of 99.99%.The amount of gasses from the condensation reactor,crude receiver and
foreshots receiver are already included in the vent flowmeter readings used to calculate emissions in previous
sections. This section estimates maintenance emissions for the rest of the major process vessels.
B. Condensation Tower
Assume the following:
(a) void fraction in distillation columns is 40%
(b) ideal gas behavior
(c) vessels are at atmospheric pressure
(d) ambient temperature(25 deg C)
(e) gases are 68%acid fluorides and 32%non-acid fluorides
(f) average molecular weight(MW)for acid fluoride component based on the average
computed from composite composition as shown on'Vessel Compositions"worksheet.
Therefore the average molecular weight for condensation is 362
(g) average MW for non-acid fluoride component= 166 (average of HFPO&HFP)
(h) number of deinventory events= 1

2021 AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION
Emission Source ID No: NS-C
Emission Source Description: VE-South PEPM Manufacturing Process
Process&Emission Description: The VE-South PEPM manufacturing process is a continuous chemical reaction.
All emissions from the process are vented to the Thermal Oxidizer/Scrubber System(TO)(Control Device ID No.
NCD-QI/Q2)which has a documented control efficiency of 99.99%for all VOC and PFAS compounds.The control
of emissions of specific compounds will be addressed and detailed in the following pages.
Basis and Assumptions:
-A process flowsheet,developed from operating data during a typical month,May 2005,is the basis for
relative concentrations of before-control emissions of gaseous wastes.
-The flowsheet is available under the"flowsheet"tab for reference and includes the basis for ratios used
in this calculation.
-Because an overall material balance for the year is used for calculation of emissions,"maintenance
emissions"related to turnarounds are assumed to be included with the calculated emissions.The usual
practice is to deinventory liquids and then vent vessels to the Waste Gas Scrubber.
-All emission determination calculations are available on the EXCEL spreadsheet found at:

COF2 is vented from the PAF column and condensation process. Because amount vented depends on the
product split,the composition exit the PAF column is calculated using the following relationship from the
flowsheet,which relates COF2 in feed to condensation to the overall amount of PMVE produced:
kg COF2 in Condensation feed = 0.555
kg PMVE produced X 320,840 kg PMVE produced
178,077 kg COF2 fed to condensation
COF2 vented from PAF column is determined from a material balance on the column:
COF2 vented from PAF column=COF2 fed to PAF column-COF2 fed to condensation
COF2 fed to PAF column = 65.24 kg/h average precursor feed,(1066FC)
X 6739 hours of operation(from uptime data)
X 55%typical COF2 in precursor feed to PAF column
241,809 kg COF2 fed to PAF column
COF2 vented from PAF column=
241,809 - 178,077 = 63,732 kg
COF2 vented from condensation(primarily the reactor vent)will also vary with product split,and is
therefore estimated using a relationship from the flowsheet:
kg COF2 vented = 0.059
kg PMVE produced X 320,840 kg PMVE produced
COF2 vented from condensation= 18,981
Total COF2 vented from process vents to TO=

PAF vented from condensation(primarily the reactor vent)will also vary with product split,and is therefore
estimated using a relationship from the flowsheet:

Process&Emission Description: The VE-South PPVE manufacturing process is
a continuous chemical reaction. All emissions from the process are vented to the
Thermal Oxidizier/Scrubber System(Control Device ID No.NCD-Q1/Q2)which
has a documented control efficiency of 99.99%for all VOC and PFAS compounds.
The control of emissions of specific compounds will be addressed and detailed in
the following pages.
Basis and Assumptions:
-The VE South's PPVE process emissions are based on the calculated emissions
from the VE North's PPVE Process,since both processes produce the identical
product with the identical process steps. Hence the VE South's PPVE emissions
are determined using the calculated emission factor for each speciated compound
per kilogram of PPVE produced.

RSU Process(NS-D)
Introduction
Page 1 of 11
2021 Air Emissions Inventory Supporting Documentation
Emission Source ID No.: NS-D
Emission Source Description: Nafion RSU Process
Process and Emission Description:
The RSU process is a continuous manufacturing process. All emissions from this
process vent to the Thermal Oxidizer/Scrubber System (TO), Control Device ID NCD-
Q1/Q2, which has a control efficiency of 99.99%. The control of VOC and PFAS
emissions will be addressed in the attached spreadsheet.
Basis and Assumptions:
The RSU process fowsheet#4 (W1207831) is used as a basis for relative
compositions and flow rates of vent streams to the division WGS. A 30 kg/hr maximum
RSU production rate is used as the basis for maximum vent rates.
Information Inputs and Source of Inputs:
Information Input Source of Inputs
RSU production quantity RSU Production Facilitator
Speciated emission rates RSU Process Flowsheet#4 (W1207831)
Point Source Emissions Determination:
Point source emissions for individual components are given in the following pages. A
detailed explanation of the calculations are attached.
Equipment Emissions and Fugitive Emissions Determination:
Emissions from equipment leaks which vent as stack (point source) emissions and true
fugitive (non-point source) emissions have been determined using equipment
component emission factors established by DuPont. The determination of those
emissions are shown in a separate section of this supporting documentation. Per PHA
07-12 Rec# 3, a Scrubber was installed in the RSU process that would scrub any RV
release from equipment inside the tower and also any leak that occurred inside the RSU
tower. Therefore, any equipment emissions from equipment inside the RSU tower will
be scrubbed. However since the efficiency of the Scrubber has not been documented
and the fact that the equipment emissions are extremely small for the RSU process, we
have elected not to take credit for the Scrubber in regards to equipment emissions.

Emission Summary
Page 9 of 11
Fugitive and Equipment Emissions Determination (Non-point Source):
Fugitive(FE) and Equipment Emissions(EE) are a function of the number of emission points in the
plant(valves,flanges, pump seals). The inventory shown below is conservative and based on plant
and process diagrams. Note that the calculations below include equipment emissions inside
as well as equipment emissions outside(fugitive emissions).
A. Equipment emissions from SU Reactor, Rearranger, RSU Still and RSU Hold Tank:
Emissions are vented from equipment located inside the RSU barricade and are vented to a vent
stack.
Barricade:
Valve emissions: 250 valves x 0.00036 Ib/hr/valve = 0.090 Ib/hr EE
Flange emissions: 550 flanges x 0.00018 Ib/hr/flangE = 0.099 Ib/hr EE
Total equipment emission rate = 0.189 Ib/hr EE
Hours of operation = 2,409
On average 0.13 Ibs of HF are produced for every 1 lb of RSU, SU or PAF.
VOC: 0.189 Ib/hr EE HF: 0.189 Ib/hr EE
x 2409 hours/yr x 2409 hours/yr
= 455.3 Ib/yr VOC from EE x 0.13 lb HF per lb VOC
59.2 Ib/yr HF from EE
B. Fugitive Emissions From S03 Storage Tank and Vaporizer
This equipment is not inside a building,therefore emissions are true Fugitive Emissions
Valve emissions: 85 valves x 0.00036 Ib/hr/valve = 0.031 Ib/hr FE
Flange emissions: 180 flanges x 0.00018 Ib/hr/flangE = 0.032 Ib/hr FE

Waste Liquid Stabilization (NS-E)
Page 1 of 9
2021 Air Emission Inventory Supporting Documentation
Emission Source ID No.:NS-E
Emission Source Description: Nafion Liquid Waste Stabilization
Process &Emission Description:
The Fluoromonomers liquid waste stabilization is a continuous system of storage with batch
neutralization. To comply with the regulatory requirements of RCRA Subpart CC, neither the
storage tank nor the reactor vent during normal operating conditions. All venting from this system
occurs as a non-routine maintenance activity,which is detailed in the following pages.All
emissions from this system are vented through the Thermal Oxidizer/Scrubber System (TO)
(Control Device ID No.NCD-Q1/Q2)which has a documented control efficiency of 99.99%for
acid fluoride compounds. The control of emissions of specific compounds will be addressed and
detailed in the following pages.
The Nafion liquid waste stabilization process emits compounds in the acid fluoride family. In the
presence of water,these acid fluorides will eventually hydrolyse to hydrogen fluoride. For the
purpose of this emissions inventory, a conservative approach will be take and the acid fluorides
will be reported both as a VOC and as the equivalent quantity of hydrogen fluoride.
Basis and Assumptions:
- For the HF emissions the entire gas flow is assumed to be HF
- The VOC emissions are assumed to be 30%COF2 and 70%TAF for the Reactor
- The VOC emissions are calculated based on Trimer and RSU for the Storage Tank
- The ideal gas law is used.

Stack Emissions from Maintenance Activity or Emergency Activity for the Reactor
Background
Before performing maintenance on the reactor or storage tank,the pressure from the system is vented to the
Thermal Oxidizer/Scrubber System(TO),Control Device ID NCD-Q1/Q2,which has a control efficiency of
99.99%. Each vent is recorded in IP21 by the weight before and after the vent.There can be times when the
pressure in either the reactor or storage tank rises rapidly due to reaction. During these times if the pressure
rises above 700 kpa in either tank,a pressure control valve can be opened to vent the tank to avoid the relief
valve opening.
Sample calculation using maintenance activity dated 10/12/21

MMF Process Fugitive/Equipment Emissions
Page 10 of 12
Fuqitive and Equipment Emissions Determination (Non-point Source):
Fugitive (FE) and Equipment Emissions (EE) are a function of the number of emission points in the
plant (valves, flanges, pump seals). The inventory shown below is conservative and based on plant
and process diagrams. Note that the calculations below include the following: (1) equipment
emissions not inside buildings, which are"fugitive" in nature and will be reported as such, and
(2) equipment emissions in side buildings, which are not"fugitive" in nature and will be reported as
equipment emissions only.
A. Fugitive emissions from MMF equipment outside of the barricade:
Emissions from this equipment are not inside a building and are therefore"fugitive" in nature.
Valve emissions: 757 valves x 0.00036 Ibs/hr/valve = 0.273 Ibs/hr EE
Flange emissions: 2,271 flanges x 0.00018 Ibs/hr/flange = 0.409 Ibs/hr EE
Pump emissions: 4 pumps x 0.00115 Ibs/hr/pump = 0.005 Ibs/hr EE
Total equipment emission rate = 0.686 lbs/hr EE
Days of operation = 66
On average 0.13 Ibs of HF are produced for every 1 pound of process material released
VOC: 0.686 Ibs/hr EE HF: 0.686 Ibs/hr EE
x 1,343 hrs/year x 1,343 hrs/year
921.2 Ibs/yr VOC from EE x 0.13 Ibs HF per lb VOC
119.8 Ibs/yr HF from EE
B. Equipment Emissions From MMF Reactor and Transfer Tank
This equipment is inside a building, therefore emissions are not true Fugitive Emissions
Valve emissions: 90 valves x 0.00036 Ibs/hr/valve = 0.032 Ibs/hr FE
Flange emissions: 270 flanges x 0.00018 Ibs/hr/flange = 0.049 Ibs/hr FE
Total fugitive emission rate = 0.081 Ibs/hr FE
VOC: 0.081 Ibs FE/hr HF: 0.081 Ibs FE/hr
x 1,343 hrs/year x 1,343 hrs/year
= 108.8 Ibs/yr VOC from EE x 0.13 Ibs HF per lb VOC

Note: Speciated equipment emissions were estimated by assuming that each
compound's equipment emission concentration was equal to that compound's
stack emission fraction of the total stack emission (excluding CHY whose
emissions are completely accounted for as Stack Emissions).
Example: The DMC equipment emissions were determined by the ratio of the
DMC stack emission (0.1 Ibs) divided by the total stack emission (0.4 Ibs)
minus the CHY stack emissions (0.2 Ibs) or 0.1 Ibs, which is multiplied by
the total fugitive emissions (921.2 Ibs)
Specifically: 0.1 921.2 = 638.4 Ibs DMC

Fugitive and Equipment Emissions Determination(Non-point Source):
Fugitive(FE)and Equipment Emissions(EE)are a function of the number of emission points in the plant(valves,flanges,
pump seals). The inventory shown below is based on plant and process diagrams. Note that the calculations below
include equipment emissions which will not be controlled by the thermal oxidizer.
A.Fugitive emissions from Resins equipment:
Emissions from this equipment are calculated using the DuPont Excellent emission factors,the number of components,
and the composition of each process stream.
Valve emission rates: 0.00036 Ib/hr/valve
Flange emissions: 0.00018 Ib/hr/flange

Methanol can potentially be emitting from two tank vents in Polymerization.The Recovery Tank operates at a low enough temperature that no methanol exists in the vapor space,thus no methanol is released.
The Recirculation Tank vents whenever condensed liquid is introduced into the tank.This calculation is based on a Vapor-Liquid Equilibrium calculation for E2,VE,and methanol.
There is also a vent of Methanol from the Conservation Vent on the Methanol tote.

Introduction
Page 1 of 3
AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION
Emission Source: IXM Membrane Process
Emission Source ID No.: NS-H
Process Description: The resin membrane treatment process (hydrolysis) is carried out continuously
by passing the film resin or laminated resin membrane through a succession of
tanks containing the necessary reagent chemicals to complete the hydrolysis
reaction. Chemically, the objective is to expose the membrane to the reagent
solution under conditions of time, temperature, concentration and agitation
which are sufficient to complete the desired reaction. Mechanically,the objective
is to convey the sheet, that is changing in dimension as it reacts, through a
series of vertical passes, in a number of tanks, in a straight line, at a constant
tension, without folding, creasing or tearing.
The resin membrane treatment process is contained in a enclosed room. All
emissions are contained within the room and vent through emission control
stacks. Air is supplied into the room and vented on a once through basis.
The resin membrane treatment process (extrusion) is carried out continuouly by
melting resin polymer pellets into an single screw extruder, heating to high
temperatures so as to melt the resin polymer and extruded into film sheet form.
The resin membrane treatment process (extrusion) is contained in an enclosed
room. All emissions are contained within the room and vented through emission
control stacks. Air is supplied into the room and vented on a once through basis.

IXM Membrane Coating Process (NS-1) Introduction
Page 1 of 7
2021 Air Emissions Inventory Supporting Documentation - Introduction
Emission Source ID No.: NS-1
Emission Source Description: lXM Membrane Coating Process
Process and Emission Description:
The lXM Membrane Coating Process is a batch process in which Nafion®
membranes are spray coated with zirconium oxide and SR resin to enhance
the performance of the membrane. The zirconium/resin is applied to the
membrane as a dispersion in a mixture of ethanol, 1-propanol, and 2-
propanol. A small amount of a high molecular weight surfactant (Triton X-
100) is added to improve the wettability of the coating on the membrane.
All VOC emissions are exclusively from the evaporation of the alcohols,
which make up 78.37% by weight the total mass of the sprayed coating.
Sources of VOC emissions are the three tanks (Binder Storage Tank, Hi-
Speed Dispersion Tank, and Paint Supply Tank), the Spray Booth Operation,
and clean-up of the equipment using 2-propanol. The VOC emissions are
uncontrolled.
The particulate matter (PM) emissions would be exclusively from the
zirconium oxide, the SR resin, and the Triton X-100 surfactant, which make
up 18.13% by weight the total mass of the sprayed coating. Overspray is
captured by paint arrestors, currently a double-layer of the Research
Products Spra-Gard Paint Arrestors Model 3232. Testing of a double layer of
the paint arrestors showed that they were 99.77% efficient in removing the
paint spray droplets from a conventional air gun. Tlt is assumed the paint
arrestor control efficiency is 98%.
Basis and Assumptions:
The lXM Membrane Coating Process total VOC emissions are based on the
total quantity of binder and coating consumed during the calendar year, and it
is assumed that 100% of the alcohols (VOCs) in the binder and coating
become air emissions.
The standard paint batch recipe presented below is used in the calculations
Ethanol 76.59%
1-propanol 11.55%
2-propanol 3.72%
Water 4.39%
SR Resin 3.75%

IXM Membrane Coating Process (NS-1) Introduction
Page 2of 7
The standard binder density of 0.839 kg/L is used to convert from volume to
weight.
The PM emissions are determined using the following data and assumptions:
1) the total quantity of solids, meaning zirconium oxide (ZrO2), Triton X-
100, and SR Resin, consumed during the reporting year,
2) a transfer efficiency of 40% of the sprayed solids adhering to the
membrane and 60% of the solids being the before-control PM quantity,
and
3) a conservative paint arrestor control efficiency of 98%.

Point Source Emissions Determination:
The point source emissions for individual components are given in the
following pages. A detailed explanation of the calculations are attached.
Equipment Emissions and Fugitive Emissions Determination:
The IXM Membrane Coating Process is completely inside a building,
therefore all emissions are point source and there are no fugitive emissions.
Since the total VOC emissions are based on the total quantity of binder and j
coating consumed during the calendar year, and it is assumed that 100% of
the alcohols in the binder and coating becomes an air emission, then any
equipment leaks would be accounted for in this material balance.

IXM Membrane Coating Process (NS-1) VOC Emissions
Page 4 of 7
Point Source Volatile Organic Compounds (VOC) Emission Determination
The emissions of volatile organic compounds (VOC) from the IXM Membrane Coating
Process is exclusively comprised of the ethanol, 1-propanol, and 2-propanol that are
consumed during the calendar year. These three compounds make up the solvent of the
coating that is sprayed on the Nafiona membranes, and also 2-propanol is used to clean
the tanks and ancillary equipment.
The quantities of ethanol and 1-propanol that are consumed during the calendar year,
are assumed to be completely emitted as VOC air emissions from the spray booth
operation.
The 2-propanol emitted as VOC air emissions from the spray booth operation are
determined by subtracting the quantity of 2-propanol that is collected as a solid waste
(WFN-210) from the total quantity of 2-propanol that is consumed during the calendar
year.
The emissions of these chemicals are determined through a material balance of the
quantity of binder solution consumed during the year and the composition of that binder
that results in the highest VOC emission rate, and the quantity of 2-propanol that was
consumed during the year.
The binder composition, or Chemical Weight Fraction, is assumed to be that of the "Low
SR/Zr02 Ratio, High Solids Binder" formula.
The binder density during the reporting year is conservatively assumed to be 0.839 kg/L.

IXM Membrane Coating Process (NS-1) PM Emissions
Page 6 of 7
Point Source Particulate Matter ("PM") Emission Determination
The emissions of particulate matter (PM) from the IXM Membrane Coating Process
is exclusively comprised of the SR Resin, zirconium dioxide, and Triton X-100 that
are consumed during the calendar year. These three compounds make up the
solids of the coating that is sprayed on the Nafiona membranes.
The emissions of these compounds are determined through a material balance of
the quantity of binder solution consumed during the year and the composition of that
binder, and the quantities of zirconium oxide and Triton X-100 that were consumed
during the year.
The binder composition, or Chemical Weight Fraction, is assumed to be that of the
"Low SR/ZrO2 Ratio, High Solids Binder" formula.
The transfer efficiency, or the fraction of the solids sprayed onto the membrane that
adheres to the membrane, is assumed to be before-control particulate matter
emissions.
The current paint arrestor filter spray removal efficiency is 99.37% for a single layer
and 99.77% for a double layer of arrestor filters. While two layers are actually used
in the Spray Booth, a 98% removal efficiency was assumed for the particulate
matter estimation.
The binder density during the reporting year was assumed to be 0.839 kg/L.

Background
Two vessels, Interface Tank and 55 Gal. Drum, inside the E2 Building vent to the E2 Bldg. stack(EP-NEP-1). The
Transfer Tank is vented to the Thermal Oxidizer/Scrubber System (TO), Control Device ID NCD-Q1/Q2, which
has a control efficiency of 99.99%. The crude E-fluids tote is filled on the outside on the E2 building, therefore
vented emissions from this tote are true"Fugitive Emissions."

Fugitive/Equipment Emissions
Page 10 of 12
Fugitive and Equipment Emissions Determination (Non-point Source):
Fugitive Emissions(FE)and Equipment Emissions(EE)are a function of the number of emission points in the
plant(valves, flanges, pump seals). For the equipment emission calculations the inventory shown below is
conservative and based on plant and process diagrams. Note that the calculations below include equipment
emissions inside buildings as well as vessel emissions outside(fugitive emissions).
A. Fugitive Emissions from Crude E-fluids tote:
This 180-gallon tote is filled with dry crude E-fluids from the 55 gallon drum. This material then gets transported
to the Polymers area for use. This tote can hold several batches of material. This filling activity occurs on the
outside of the E2 building. Assume the filling is at 30 degrees Celsius and assume that one batch of E-fluids
displaces 33%of the tote, or 60 gallons of volume, during filling. These emissions will be"Fugitive"in nature.

B. Equipment Emissions From Valves, Pumps and Flanges
The emission rates for valves, flanges, etc. have been established by the Chemours Company. The emission
rates from these types of equipment in the E-fluids process is considered"Excellent"and therefore the following
rates are use: valve=(0.00039 Ibs/hr), flange=(0.00018 Ibs/hr)
Calculations:
Valve emissions: 93 valves x 0.00039 Ibs/hr/valve = 0.0363 Ibs/hr VOC

2021 Air Emissions Inventory Supporting Documentation
Emission Source ID No.: NS-M
Emission Source Description: TFE/CO2 Separation Process
Process and Emission Description:
The TFE/CO2 separation process is a continuous process. All emissions from this
process vent to the Thermal Oxidizer / Scrubber System (TO), Control Device ID NCD-
Q1/Q2, which has a control efficiency of 99.99%. The control of emissions of the TFE
compound will be addressed in the attached spreadsheet.
Basis and Assumptions:
A mass balance is used as the basis for the TFE/CO2 area emissions. The TFE/CO2
emissions includes the TFE/CO2 area as well as the Polymers LJC and dryers. The flow
of TFE/CO2 into the area is divided by two in order to determine the amount of TFE fed
to the system. Then each of the end users (which includes polymers, semi-works, MMF
and RSU) determine how much they have consumed and these numbers are subtracted
from the total TFE into the system to determine the emissions. Mass flowmeters in each
area are used to determine the total input and output flows.
Information Inputs and Source of Inputs:
Information Input Source of Inputs
TFE/CO2 consumption Precursor Production Facilitator/IP21
Polymers Consumption Polymers Production Facilitator/IP21
Semiworks Consumption Semiworks Production Facilitator/IP21
MMF Consumption Precursor Production Facilitator/IP21
RSU Consumption Precursor Production Facilitator/IP21
Point Source Emissions Determination:
Point source emissions for individual components are given in the following pages. A
detailed explanation of the calculations are attached.
Equipment Emissions and Fugitive Emissions Determination:
Emissions from equipment leaks which vent as stack (point source) emissions and true
fugitive (non-point source) emissions have been determined using equipment component
emission factors established by Chemours. The determination of those emissions are
shown in a separate section of this supporting documentation.

Fugitive and Equipment Emissions Determination (Non-point Source):
Fugitive emissions (FE) are a function of the number of emission points in the plant(valves,
flanges, pump seals). The inventory shown below is conservative and based on plant and
process diagrams. Note that the calculations in A and B include only the equipment upstream
of the TFE/CO2 mass meter. Emissions in Section C would be included in the Point Source
Emissions tab since the values are obtained from the system mass balance. Section C
emissions are subtracted from the uncontrolled Point Source emissions for TFE.

HFPO Product Container Decontamination Process
HFPO and HFP product containers returned from customers are decontaminated by venting residual
hexafluoropropylene oxide ("HFPO") and hexafluorop ropy lene ("HFP") to the Thermal Oxidizer/Scrubber System
(TO), Control Device ID No. NCD-Q1/Q2, which has a control efficiency of 99.99%. To determine the amount
emitted from this process, the vapor density of HFPO and HFP is used along with the volume of the container.
To determine the amount emitted from this process, the vapor density of HFPO is used along with the volume of
the container and the number of containers decontaminated during the year. The vapor density is based on an
Aspen process simulation at 13°C. A temperature of 13°C was chosen based on the average 24 hour temperature
for Audubon, NJ, which is located 30 miles northeast of Deepwater, NJ, the location of the primary customer of
isotainers and ton cylinders (i.e. where containers are emptied).All containers are assumed to contain HFPO
vapor. Occasionally some containers may contain rearranged HFPO in the form of hexafluoroacetone (HFA),
however this should not affect vapor density since HFA has the same molecular weight as HFPO.
HFP Venting results were calculated manually for each ISO by using the Initial/Tare ISO weight with the weight
transferred to the HFP Storage Tanks on the day of offload.

Decontamination Process
Container Emissions Estimation Basis:
PPVE, PSPEVE, and EVE are the products that are shipped to customers in ISO tank
containers, LINT cylinders, 1-ton cylinders, 4BW cylinders, and 4BA/3AA cylinders from
the Vinyl Ethers North ("VEN")Manufacturing Process. Usually only PPVE is shipped in 1-
ton cylinders from the VEN area.
Empty containers returned to the site may be decontaminated by pressurizing with
nitrogen and venting to the Thermal Oxidizer/ Scrubber System (TO), Control Device ID
No. NCD-Q1/Q2, for numerous cycles. This TO has a documented control efficiency of
99.99% for VOCs. Some returned containers are filled on top of heels in cylinders without
the need to decontaminate.
To determine the amount emitted from this process, the vapor density of each component
is used along with the volume of the container.
The vapor densities are estimated using the ideal gas law equation.
It is assumed the temperature of the container systems is 77°F(25°C). It is also assumed
that when the containers are emptied they remain full of vapors.
To calculate the amount of product vented per container, the container volume is
multiplied by the vapor density.
Product Vapor Density
(lb/gal @ 25°C)
PPVE 0.0908

pressurizing with nitrogen and venting to the Thermal Oxidizer/Scrubber System (TO), Control Device ID
No. NCD-Q1/Q2, which has a control efficiency of 99.99%.
PMVE, PEVE, and PPVE are the products that are shipped to off-site customers in 1-ton cylinders, 4BW
cylinders, 4BA/3AA cylinders and ISO tank containers from the Vinyl Ethers South ("VES") Manufacturing
Process. HFPO Dimer Acid Fluoride("DAF") is loaded into ISO tank containers at the VES area for
transportation to the PPA Process. If needed, the containers are decontaminated by pressurizing with
nitrogen, venting to the Thermal Oxidizer/Scrubber System (TO) Control Device ID NO. NCD-Q1/Q2 with a
control efficiency of 99.99%, and evacuating for numerous cycles. To determine the amount emitted from
this process, the vapor density of each component is used along with the volume of the container. DAF is
determined separately.The vapor densities are estimated using the ideal gas law equation. It is assumed the
temperature of the container systems is 77°F (251C). It is also assumed that when the containers are
emptied they remain full of vapors. To calculate the amount of product vented per container, the container
volume is multiplied by the vapor density.

Container Emissions Estimation Basis:
PMVE, PEVE, and PPVE are the products that are shipped to off-site customers in 1-ton
cylinders, 4BW cylinders, 4BA/3AA cylinders and ISO tank containers from the Vinyl Ethers South
("VES") Manufacturing Process. HFPO Dimer Acid Fluoride ("DAF") is loaded into ISO tank
containers at the VES area for transportation to the PPA Process. If needed, the containers are
decontaminated by pressurizing with nitrogen, venting to the Thermal Oxidizer/ Scrubber System
(TO) Control Device ID NO. NCD-Q1/Q2, and evacuating for numerous cycles.
To determine the amount emitted from this process, the vapor density of each component is used
along with the volume of the container. DAF is determined separately.
The vapor densities are estimated using the ideal gas law equation.
It is assumed the temperature of the container systems is 77°F (25°C). It is also assumed that
when the containers are emptied they remain full of vapors.
To calculate the amount of product vented per container, the container volume is multiplied by the
vapor density.

Product (lb/gal @ 25°C)
PMVE 0.0566
PEVE 0.0737

The mass of vapor("Mvap") in a container emptied of liquid is equal to the volume of the container
("V") multiplied by the vapor density ("rvap')-
Mvap = V X rvap

HFPO Dimer Acid Fluoride
BASIS:
HFPO Dimer Acid Fluoride ("DAF") is pneumatically unloaded from an ISO Tank Container into
the PPA Process area using nitrogen gas (a.k.a. blow-casing). After unloading, the ISO Tank
Container is full of nitrogen gas at 5 psig with a small heel of liquid DAF. If the container is
decontaminated, it is done by venting the vapor headspace and any liquid heel to theThermal
Oxidizer/ Scrubber System (TO) Control Device ID NO. NCD-Q1/Q2, which has been measured
as 99.99% efficient in capturing acid fluoride compounds such as DAF.
Emissions are estimated using Raoult's Law and the initial pressure of the nitrogen-filled ISO Tank
Container.

Emission Source Description:
The lime processing system receive pebble or hydrated lime in the Lime Silo (NS-
R1) and mixes into a wet slurry in the Lime Slaker (NS-R2). A bin vent on the
Lime Silo collects dust generated during truck unloading. This baghouse is an
integral part of the process. The emissions from the lime silo were based on a
load factor of 0.02 grains per dry standard cubic feet of air that was provided by
the vendor of the baghouse and the system has a maximum air flow rate of
1,000 cubic feet per minute.
Particulate matter emissions from the Lime Silo are calculated using a vendor
supplied emission factor of 0.02 grains of PM per standard cubic feet. A
maximum air flow rate of 1,000 cubic feet per minute and the hours that the silo
was loaded were used to calculate annual emissins. Emissions of PM10 and
PM2.5 assumed to equal the emissions of PM.

Emission Source ID No. : NS-R2
Emission Source Description:
The Lime Slaker (NS-R2) mixes water and calcium oxide (pebble lime
or hydrated lime) to form a calcium hydroxide lime slurry. Fugitive
dusts from mixing pebble lime and water in the Lime Slaker will be
controlled by a wet scrubber. The lime slurry then is introduced into the
Crystallizer, along with the aqueous 18 wt% HF acid from the Thermal
Oxidizer/Scrubber System. Calcium fluoride (CaF2) crystals will form in
the Crystallizer and be fed to the batch hold-up or Filter Feed Tank.
Particulate matter emissions from the Lime Slaker are calculated using
a vendor supplied inlet emission rate to the wet scrubber of 6.17
pounds per hour and a control efficiency of 99.7%. Emissions of PM 10
and PM2.5 assumed to equal the emissions of PM.

Wastewater Treatment Plant(WTS-A)
Introduction
Page 1 of 7
2021 Air Emissions Inventory Supporting Documentation
Emission Source ID No.: WTS-A
Emission Source Description: Central Wastewater Treatment Plant
Process and Emission Description:
The Wastewater Treatment Plant (VW `TP) consists of the biological treatment of
process and sanitary wastewater utilizing extended aeration. The WWTP is
comprised of an open equalization basin and open-top tanks and clarifiers. The
basin is mixed using floating mixers and the tanks are aerated primarily with diffused
air.
Emissions from the WWTP result from the volatilization of solubilized compounds
which are air stripped via the aeration of the wastewater. The extent of the
volatilization is a function of the specific compound's solubility in water and its vapor
pressure, typically expressed as the compound's Henry's Law Constant. Also, the
volatilization of an organic compound is dependent on its rate of biodegradability. For
example, methanol which is a Hazardous Air Pollutant (HAP), is highly
biodegradable, and as such its biodegradation rate is much faster than its
volatilization rate, thereby limiting the air emissions of methanol from the WWTP.
Basis and Assumptions:
The three major compounds that are treated in the WWTP are butyraldehyde,
ethylene glycol, and methanol. Due to process shutdowns from Kuraray, butaldehyde
and methanol were not sent to the WWTP during CY2021.
The emissions of methanol from the WWTP were determined using the EPA
WATER8 model. This modeling takes into account the specific operational units of
the WWTP to predict the ultimate fate of specific compounds.
P p P
The Henry's Law Constant for ethylene glycol is 6.0 x 10e-08 atm-m3/mole. Not
surprisingly, ethylene glycol is exempt from the wastewater control requirements of
40 CFR 63 Subpart G as ethylene glycol is excluded from Table 9 of that subpart.

Wastewater Treatment Plant(WTS-A)
Introduction
Page 2 of 7
Because of the above, it will be assumed that the VWVfP unit operation's emission
factors for ethylene glycol are the same as those for dimethylformamide. However,
the biodegradation rate of ethylene glycol will be assumed to be the same as that of
methanol, since the technical literature found in the Handbook of Environmental Data
on Organic Chemicals indicates that for an acclimated system, ethylene glycol is
biodegraded at twice the rate of methanol. To be conservative, the slower methanol
rate will be used.
The Henry's Law Constant for butyraldehyde is 1.15 x 10e-04 atm-m3/mole which is
higher than the Henry's Law Constant for methanol of 4.55 x 10e-06 atm-m3/mole,
meaning the quantity that is air stripped from the wastewater would be expected to be
higher than that for methanol. According to the Handbook of Environmental Data on
Organic Chemicals, butyraldehyde is biodegraded at the same rate of methanol in an
acclimated system.
Because of the above, it will be assumed that the VWVfP unit operation's emission
factors for butyraldehyde are twice as those for methanol.
Dimethyl sulfoxide (DMSO) is a minor compound in the VWVfP influent. The fugitive
emissions of DMSO are estimated separately from the above compounds.
The VWVTP is fed 30% aqueous ammonia as a nutrient for the biological microbes.
To be conservative, the emissions of ammonia from the VWVTP will assume that
none of the NH3 is utilized by the microbes, who would convert the ammonia into
nonvolatile nitrate. The emissions of ammonia is determined using Henry's Law.

the reports beginning calendar year 2012. It is believed that an acclimated biological
system would be able to biodegrade 85% these simple organic compounds during the 18-

Emission Source Description: Central Wastewater Treatment Plant
Ammonia (NH3) Emissions
The wastewater treatment plant ("VW TP") is fed aqueous ammonia (30% NH3) as a
nutrient for the biological microbes.
In 2021, the VWV>-P consumed 31,080 pounds of 30% NH3 aqueous ammonia, which
equates to 9,324 pounds of 100% ammonia (100% NH3).
The aqueous ammonia is fed directly into the VWVTP Aeration Tank that is aerated via
2,000 cubic feet per minute of diffused air injected into the bottom of the tank. To be
conservative, the emissions of ammonia from the VW TP will assume that none of the NH3
is utilized by the microbes, who would convert the ammonia into nonvolatile nitrate.
The VWVTP influent averages approximately one (1) million gallons of water per day, which
is equal to 3,044,100,000 lb. of water per year.

Emission of NH3 from the WWTP Clarifiers
The final wastewater treatment unit operation are the clarifiers in which the biomass is
separated from the treated process wastewater through gravity settling. The clarifiers are
quiescent tanks with no mixing or aeration. Any emissions of ammonia from the clarifiers
would be a small fraction of the estimated ammonia emissions from the Aeration Tank.
To be conservative, it will be assumed that the emissions of ammonia from the clarifiers
are equal to the ammonia emissions from the Aeration Tank.
Emission of NH3 from the WWTP Clarifiers = 178 Ibs NH3/year
Total Emission of NH3 from the WWTP System (ID No. WT-A)
Emission of NH3 from the VW -FP Aeration Tank = 178 Ibs NH3/year

Emission Source ID No. : WTS-B and WTS-C
Emission Source Description:
The Specific Conditions for the Impingement Type Wet Scrubber(ID No.WTCD-1)are discussed
in Part 1 Section 2.1(E)of the site's Title V Air Permit. The Permit states that the scrubber is to
control the"odorous emissions from the wastewater treatment sludge dryers(Nos. WTC-B and
WTS-C)."
Major categories of offensive odors from the drying of activated sludge could generally be
grouped into the following:
Odor Threshold of
Odor Category Common Chemical in Common Chemical
Odor Category (ppmv)
Amines Methyl amine 0.021
Ammonia Ammonia 1.5
Hydrogen sulfide Hydrogen sulfide 0.13
Mercaptans Methyl mercaptan 0.002
Organic sulfides Dimethyl sulfide 0.001
Skatole 3-Methyl-1 H-indole 0.019
Based on the lack of odors coming from the discharge of the WWTP Sludge Dryer scrubber, and
the low odor threshold of the possible odorous compounds coming from the scrubber, it is
believed that only an insignificant amount of VOCs could be emitted from this source.
To quantify the worst-case scenario, it will be assumed that the scrubber is running continuously
during the entire year with the above compounds being vented at their odor threshold
concentration. This is an obvious overstatement of actual emissions since the WWTP Scrubber
normally operates with no detectable odors.
Conversion of concentration expressed as ppmv to mg/m3 is via the following equation:
mg ppmv x 12.187 x Molecular Weight
m3 (273.15 + Temperature)°C
For the purpose of this concentration conversion, it will be assumed that the actual scrubber
discharge temperature is a constant 27°C. Therefore, the above equation reduces to:
m
m3 = 0.0406 x ppmv x Molecular Weight
For example, converting 0.021 ppmv of methyl amine(MW=31)to mg/m3 follows:
0.0406 x 0.021 ppmv x 31 grams
e = 0.026 mg

Emission Source Description: Waste DMSO Storage Tank
Process and Emission Description:
This tank is used as an intermediate storage space for disposal of DMSO
(dimethyl sulfoxide) offsite. DMSO is used in the Hydrolysis process and
cannot currently be disposed of onsite. When the material in Hydrolysis can no
longer be used for the process, the chemical is transferred to the Waste DMSO
Storage Tank. From this tank, the waste DMSO solution is pumped to the
facility's NPDES permitted wastewater treatment plant for disposal. The tank
vents to the atmosphere through a gooseneck pipe with a conservation vent
coming off the top that ends 12" above the diked area.
Basis and Assumptions:
- Direct vent to atmosphere
- Tank volume= 6000 gallons or 802 ft3
- DMSO vapor pressure = 0.46 mm Hg @ 20°C
- Molar volume of an Ideal Gas @ 0°C and 1 atm= 359 ft3/(Ib-mole)
- Molecular Weight of DMSO = 78 (78 lb DMSO/lb-mole DMSO)
- Assume one complete tank volume turnover per month for point source emissions.
- Assume"Good" Emission Factor on Equipment Leaks for fugitive emissions (See Appendix A).
- Flange emissions were used for all equipment except valves and pumps.

Fugitive Emissions Determination
Fugitive emission studies have been done on a number of DuPont facilities and the measurements
were considerably lower than emission factors recommended by the EPA for SOCMI chemical
processes. These screening and bagging data have been used to establish"typical"emission factors
from DuPont facilities. The data separated into three categories of emission levels for"as found"
emissions form plants who were not involved in LDAR programs.
As a result of this effort, three sets of DuPont factors were developed: "superior", "excellent", and
"good." The superior factors are typical of processes that contain extremely hazardous materials, i.e.
phosgene(COC12), chlorine(C12), and hydrogen fluoride(HF). A set of example questions to help
guide DuPont sites as to when to use the different categories was also developed and is discussed in
the next section. The three categories represent the range found at DuPont facilities, but still are much
lower than EPA SOCMI factors. All three sets of factors are listed below.

Note a : Sodium hypochlorite has a vapor pressure of 17 mmHg (2.26 Kpa) at 20 degrees C. Per 40 CFR 63
Subpart H, "light liquid service" means equipment whose contents have a vapor pressure of greater than 0.3
kilopascals at 20 degrees C. Therefore, for the purpose of determining fugitive emissions from the river water
chlorination system, the sodium hypochlorite equipment is considered to be in "light liquid service" even though
sodium hypochlorite is not an organic compound.

2021 Air Emissions Inventory Supporting Documentation
Emission Source ID No.: 1-07
Emission Source Description: Paint Shop
Process and Emission Description:
The Chemours Company - Fayetteville Works operates a Paint Shop in which
product cylinders and assorted metal parts are painted.
Basis and Assumptions:
The painting activity at this source is fairly frequent. Most of the painting is of the
Fluoromonomer product cylinders. The basis of the emissions determination is the
historical actual consumption records of paints and primers used at this source.
This activity results in very low overall emissions of both VOC and HAP/TAP
emissions. In addition, the type and brand of paints consumed varies dramatically
each year. As such, the effort to accurately quantify and qualify the emissions from
this activity is much greater than the relative scale of the emissions.
Therefore, a conservative approach will be used to determine the air emissions, in
which it will be assumed that all the paint consumed was 100% VOC by mass, that
all of the paints' density is 12.71 Ibs/gal which is the greatest known density of a
previously used paint, and that each paint has the highest concentration of
HAP/TAP of anv previously used paint.

The Chemours Company - Fayetteville Works has several small spray paint booths
located throughout the site. The function of these spray booths is to perform
occasional painting of metal parts using aerosol spray cans.
Basis and Assumptions:
The painting activity in these spray booths is very infrequent. Some spray paint
booths are used once or twice a year. However, for the purposes of this air
emissions inventory, it will be assumed that a extremely conservative high estimate
exists:
(1) While most if not all of the paint spray booths are used less than one day
per month, it will be assumed that each spray booth has five (5) aerosol
cans of paint emptied into it each day, five days per week.
(2) Most commercial spray paints contain 60% to 65% VOC. However, for the
purpose of this report, it will be assumed that the paint is 100% VOC by
weight.
(3) To account for the emission of hazardous air pollutants, it will be assumed
that the paint contains the highest concentration of the individual HAPs per
the Material Safety Data Sheets for Krylon and Rust-oleum paints.
