[9' All known operating scenarios, control devices, and emission release points have been entered for each emission source (permitted,
insignificant, and unpermitted) or note that the emission source was not operated or not required to report.
E'7 Check if SCC codes for each OS are accurate and update if needed.
Evaluate "U" sources for significance and address according to policy.
Calculations / forms appear to add up correctly.
All compliance issues are being addressed (e.g. Toxics limits, above TV thresholds, large emissions increase/decrease, installation
without a permit).
l" All volatile HAPs/TAPS were included in the VOC total.
[E' Calculations and control efficiencies appear correct. Emission factors are the best available and most current factors appropriate
for the reporting facility (e.g. stack testing, AP-42, etc.).

DAQ's Comments Regarding Inventory
CO emission increased by 10% due to a 200% increase in production of vinyl ethers. SO2 emission increased due to higher usage of
SO2 in the nafion RSU process. VOC emissions were reduced by 12.6% due to the sale of the Butacite and SentryGlas facilities to
Kuraray, removing these processes from the Chemours permit Arsenic emissions decreased by 16.2%, beryllium metal emissions
decreased by 66.7%, lead emissions decreased 53.6%, manganese emissions decreased by 12.8%, methyl chloroform emissions
decreased by 99.8%, polycyclic organic matter emissions decreased by 99.8%, and selenium emissions decreased by 86.4% due to
the boilers not firing #6 fuel oil during 2015. Ammonia emissions increased 10.4% due to somewhat higher usage of ammonia in th,
wastewater treatment process. CFC-113 emissions increased by 70% due to higher production levels in the Nafion semiworks
process. Chlorine emissions increased by 31% due to higher chlorine usage in the wastewater treatment process. Methanol
emissions decreased 12.8% due to reduction of the amount of wastewater handled during 2015. Methylene Chloride emissions
increased due to more leakage and spills from the Nafion membrane coolant systems. Sulfuric acid emissions decreased by 12.9%
due to decreased production levels in the nafion RSU process and the polymer processing aid process Ethyl Benzene emissions
increased by 76%, ethylene glycol emissions increased by 53%, MEK emissions increased by 75.8%, toluene emissions increased by
34.2%, and xylene emissions increased by 53.4% due to higher paint usage by the maintenance department Formaldehyde
emissions showed an apparent emissions increase of273%, but it appears there was an error in the input of the emissions for 2014
that accounts for this increase.

Supportin2 Documentation for WWTP Slud e Dryers (WTS-B and WTS-C
The Specific Conditions for the Impingement Type Wet Scrubber (ID No. WTCD-1) is 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:

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:
mg in = 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 my x 31 grams = 0.026 mg

AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION

Emission Source Description:
Process a
FS-B
Polyvinyl Fluoride Process No. 1
nd Emission Description:
The PVF process is a continuous manufacturing process. All emissions from this
process vent to the atmosphere, some via a vertical stack. The calculation of emissions
of VOCs will be addressed in the attached spreadsheet.
Basis and Assumptions:
FEP-131 (Analytical Equipment) emissions are calculated using the flowmeters feeding
the analyzers and the rotometers in the GC bypass loops (which are not routinely valved
to the stack).
FEP-132 (Maintenance Header) is only in operation when equipment is vented for
maintance. A flowmeter is installed immediately upstream of the VF Dispersion Stack.
Procedure requires the line to be purged with N2, then vent VF and then purged with N2
at least 3 times to remove low concentrations of VF. After maintenance air is removed
by purging the equipment with N2 an additional 3 times (min). In July of 2011, a
densitometer was installed, calibrated and verified. The densitometer accurately
measures the percent of VF in the gas leaving via the maintenance vent header, giving
an accurate emission total for that source. The year's Maintenance Header emissions
FEP-133 (Flash Tank) emissions are based on the operating pressure, temperature, and
flow through the Low Pressure Slurry Separator. It is assumed that if VF Flow to the
PVF reactor is less than 1000 pph, then there is no VF leaving the Flash Tank.
FEP-134 (Product Collection System) emissions are based on the operating time and
production rate of the baghouse and the bag efficiency. According to the manufacturer,
W.L. Gore, the Baghouse bags have a 99.97% efficiency rating on 0.3 micron
particulate. We don't expect to have any particles smaller than that, so emissions will
be 0.488 lb. PVF particulate emission per Polymer Production Unit (PPU).

PVF-1 Process PM Determination (Emission Source ID Nos. FS-B)
Year 2015
Basis and Assumptions:
FEP-64 (Product Collection System) emissions are based on the operating time and
production rate of the baghouse and the bag efficiency. According to the manufacturer,
W.L. Gore, the Baghouse bags efficiency rating on 0.3 micron particulate indicates the
potential particulate emissions would be 0.488 lb. particulate matter ("PM") per Polymer
Production Unit ("PPU°). It is not expected that any particles would be smaller than 0.3
micron.

nd Emission Description:
The PVF process is a continuous manufacturing process. All emissions from this

of VOCs will be addressed in the attached spreadsheet.
Basis and Assumptions:
FEP-C1 (Analytical Equipment) emissions are calculated using the flowmeters feeding
the analyzers and the rotometers in the GC bypass loops (which are not routinely valved
to the stack).
FEP-C2 (Maintenance Header) is only in operation when equipment is vented for
maintance. A flowmeter is installed immediately upstream of the VF Dispersion Stack.
Procedure requires the line to be purged with N2, then vent VF and then purged with N2
at least 3 times to remove low concentrations of VF. After maintenance air is removed
by purging the equipment with N2 an additional 3 times (min). It is therefore
conservatively assumed that 50% of the flow is VOC (VF or Propylene) when
densitometer data is not available (January -April). In May of 2012, a densitometer was
installed, calibrated and verified. The densitometer accurately measures the percent of
VF in the gas leaving via the maintenance vent header, giving an accurate emission
total for that source. The year's Maintenance Header emissions are calculated using
data from the densitometer from May through December and in January through April,
50% of the flow was assumed to be VOC.
FEP-C3 (Flash Tank) emissions are based on the operating pressure, temperature, and
flow through the Low Pressure Slurry Separator. It is assumed that if VF Flow to the
PVF reactor is less than 1000 pph, then there is no VF leaving the Flash Tank.
FEP-C4 (Product Collection System) emissions are based on the operating time and
production rate of the baghouse and the bag efficiency. According to the manufacturer,
W.L. Gore, the Baghouse bags have a 99.97% efficiency rating on 0.3 micron
particulate. We don't expect to have any particles smaller than that, so emissions will
be 0.488 lb. PVF particulate emission per Polymer Production Unit (PPU).

2015 Air Emissions Inventory Supporting Documentation
Emission Source ID No.: GHG-HDR
Emission Source Description: HFA-Hydrate Destruction Reactor System
Process and Emission Description:
The HFA-Hydrate Destruction Reactor System (HDR) consists of a thermal -alkaline
reactor that decomposes HFA-hydrate to trifluoromethane (HFC-23 or fluoroform) and
trifluoroacetate. The trifluoroacetate is water soluble and leaves the HDR system in the
wastewater stream. The HFC-23 is vented to the atmosphere via the Nafion® Process'
main vent stack (NEP-1).
HFC-23 is not a VOC, HAP, or North Carolina TAP. As such, HFC-23 is not a regulated
air pollutant. Because of this, the HDR is not listed on the site's Title V Air Permit.
Therefore, for the purpose of this report, HFC-23 is reported as a greenhouse gas emission.
Basis and Assumptions:
The basis of the HFC-23 emissions is the formation of HFA-hydrate in the HFPO Process.
In the HDR system, the HFA-hydrate is chemically decomposed to HFC-23. Per the HFPO
Process flowsheet (W1208078), 0.4 kg of HFC-23 is formed and emitted for every 30.48
HFP Units fed into the HFPO Process. Therefore, the emission of HFC-23 is proportional
to the quantity of HFP make-up fed to the HFPO Process. Vent testing of the HFPO
Process has established the HFC-23 emission factor for that process. Therefore the
emissions of the HFC-23 from the HDR system is simply the difference between the total
HFC-23 emissions and the HFPO Process' HFC-23 emissions.

The amount of CF3H emitted from the HFPO Process is based on the before -control CHF3
emissions factor documented in TA NF-11-1824 from the stripper column vent.
ECF3H= 0.0114 kg CHF3 / HFP Units fed to process
Therefore the amount emitted from the HFPO process is:
0.0114 kg CHF3 x 583,653 HFP Units = 6,672 kg CHF3
1.00 HFP Units
14,709 lb. CHF3
Therefore the quantity of trifluoromethane emitted from the HFA-hydrate Destruction Reactor
System (GHG-HDR) would be the difference between the total CHF3 emissions and the quantity
emitted from the HFPO Process (NS-A).
16,884 lb. CHF3 minus 14,709 lb. CHF3

Determination of Actual PM-10 Emissions: PVF-1 House Vacuum System
Particulate Matter Emissions Determination
For general good housekeeping purposes, the DuPont PVF-1 Process uses a vacuum system
(ID No. PVF-Vac-A) to remove any PVF resin powder (particulate matter) from the building's
floor and equipment. The emission of particulate matter from this vacuum system is
controlled by a two -stage fabric filter.
The 1st -stage fabric filter (Control Device ID No. CD-PVF-Al) is a TDC Filter QX blended
cellulous / synthetic fiber paper filter. Its efficiency for capturing / controlling particles is 48%
for 0.3 - 1.0 micron size, 88% for 1.0 - 3.0 micron size, and 99% for 3.0 - 10.0 micron size.
The 2nd-stage fabric filter (Control Device ID No. CD-PVF-A2) is a TDC Filter SB-ME
heavy-duty spunbond 100% polyester metalized spunbond filter media with a conductive
coating to prevent static buildup. Its MERV Test results shows the filter's efficiency for
capturing / controlling particles is 38% for 0.3 - 1.0 micron size, 72% for 1.0 - 3.0 micron
size, and 98% for 3.0 - 10.0 micron size.
Determination of before -control particulate matter is based on the conservative estimate of
8,160 lb/yr collected from the 1st -stage filter, the capture efficiencies of that filter, and the
particle size distribution of the PVF resin powder.
Results of particle size distribution testing of batches of PVF resin powder during August
through October 2013 showed the worst -case situation of 68% being less than 1.0 µm. To be
conservative, assume 70% is less than 1.0 µm and 30% is greater than 1.0 µm.
Vendor literature from TDC Filter states the capture / control efficiency of their QX Filter is
48% for particles less than 1.0 µm and 88% for particles greater than 1.0 µm.
The quantity of particulate emissions that is captured / controlled by the 1st -stage filter is
8,160 lb. per year and is equal to the following:

Process 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 can not currently be disposed of
offite. 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 is
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/(lb-mole)
- Molecular Weight of DMSO = 78 (78 lb DMSO / lb -mole DMSO)
- Assume one complete tank volume turnover per day for point source emissions.
- Assume "Good" Emission Factor on Equipment Leaks for fugitive emissions (See

APPENDIX A: FUGITIVE EMISSION LEAK RATES FOR PROCESS EQUIPMENT
Fugitive emission studies have been done on a number of DuPont facilities and the measurements
were considerable 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 (COC 12), chlorine (C 12), 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.

equipment is considered to be in 'light liquid service" even though sodium hypochlorite is not an
organic compound.

Process and Emission Description:
The Chemours Company - Fayetteville Works has several laboratories located throughout
the site. The use of normal laboratory chemicals result in assumed emissions of these
compounds.
Basis and Assumptions:
The amount of the laboratory chemicals used in the various laboratories is not easily
quantified due to the current procurement procedures. In previous years these quantities
could and were determined. During those years, it was assumed that 100% of the
laboratory chemicals purchased were emitted as air emissions.
To be conservative, it will be assumed that the annual emission of laboratory chemicals is
the summation of the emissions that occurred in the four (4) year period from 2003 to
2006.

Process and Emission Description:
The Chemours Company - Fayetteville Works has a free-standing structure that is used to
abrasive blast large metal parts prior to painting.
Basis and Assumptions:
The abrasive blasting activity in this structure is infrequent. Purchasing records of the
abrasive media used in this operation is the basis of the abrasive media consumption.
Per the AP-42 Section 13.2.6 particulate emission factors for abrasive blasting of mild
steel panels with a five mile per hour wind speed, total particulate matter emissions
would be 27 pounds per 1,000 pounds of abrasive. The choice of this low wind speed is
appropriate since the blasting operation is conducted inside an enclosure.

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:
1-07
Page 1 of 1
The painting activity at this souirce 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 lb/gal which is the greatest known density of a previously used paint, and
that each paint has the highest concentration of HAP/TAP of any previously used paint.
During the period from 2008 through 2014, the Paint Shop averaged 681 gallons per year.
Therefore, to be conservative it will be assumed that 750 gallons of the above described
worst -case paint was consumed during the reporting year.

Process and Emission Description:
The Chemours Company - Fayetteville Works has several small 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.

C. Acid Fluoride Solvent- mixture of TAF and TFF
Perfluoro-3,5,7,9,11-pentaoxadodecanoyl fluoride (TFF)
Trifluoromethyl ester of carbonofluoridic acid (TAF)
HF Potential:
The acid fluoride solvent is a mixture of telomeric acid fluorides (TAF) and telomeric fluoroformates (TFF).
TAF behaves as typical acid fluorides, however an average molecular weight must be used since chain length varies.
Each mole of TAF (avg MW = 330) can generate one mole of HF (MW = 20).
1 lb TAF . 1 mole TAF 20 lb HF 1 mole HF = 0.0606 lb HF
1
330 Ib TAF mole HF 1 mole TAF
Therefore, each 1 lb of TAF generates 0.061 kg of HF
Telomeric Fluoroformates break down into multiples of COF2 (MW = 66), which in turn generate 2 moles of HF (MW =20).
Using n=4 would mean for every mole of TFF, 6 moles of COF2 can be generated. MW of n=4 TFF is 396.
Nlnct TFF is helieved to be of chain length less than n=4 based on recent analysis.
l lb TFF . mole TFF 6 mole COF 2 20 lb HF 2 moles HF = 0.606 lb HF
396 lb TFF 1 mole TFF 1 mole HF 1 mole COF 2
CAS Nos. 690-43-7
3299-24-9
Therefore, each 1 lb of TFF generates 0.606 lb of HF
For the purpose of HF Potential, it will be conservatively assumed that all of the Acid Fluoride Solvent is TFF, since the potential HF is greater.

HFP sent to VE-South Process when VE-S shutdown (from "VE-S Flow" Tab): = 310 lb HFP
Additional HFP is emitted from the unloading of HFP, specifically the decontamination of hoses and compressor after each trailer is unloaded.
The decontamination involves venting the contents of the two hoses and compressor piping to the WGS.
Each hose is 2" diameter x 20 feet long.
Volume of each hose = 753.98 in = 12.36 L
The density of HFP liquid at 16C is 1.42 kg/L Determined from physical property data
The density of HFP vapor at 16C is 0.0281 kg/L Determined by ideal gas law @ 16C and vapor press of 450 kPa abs.
(pressure from H27457PG on iso container, after H27451 HV closes)
HFP vented from Liquid Hose: (assumes hose volume is filled with li uid
Volume of hose X liquid density = 17.54 1 kg from Liquid Hose
HFP vented from Vapor Hose: (assumes hose volume is filled with va or)
Volume of hose X vapor density = 0.35 kg from Vapor Hose
There is an additional estimated 20' of 1 1/2" piping between the hose and 27460HV, also decontaminated, volume = 7 L
HFP vented from vapor piping= 7 L X vapor density = 0.20 kg from Vapor Piping

Suction bottle volume is 30.2 L, typical temperature is 27C and pressure is 270 kPa(g) at time of decontamination.
Vapor density of HFP= 0.0223 kg/L Determined by ideal gas law @ 27C and 371.3 kPa (a)
Reference H27454TG & H27453PG
Additional vapor in 10' of V diameter pipe, estimated volume is 1.5 L. Total volume is 31.7 L
Suction side volume X vapor density= 0.71 kg
Discharge bottle volume is 30.2 L, typical temperature is 37C, 370 kPa (g) at time of decontamination.

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 %HFP and 50 %HFPO,
and the vapor density is 3.3 Ib/ft3 (reference ASPEN model)
The molecular sieves have a bulk density of 47 lb per ft3 of bed volume
The density of the sieves themselves is 57 lb 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= 1.429 ft3 of vapor
X vapor density of 3.3 Ib/ft3
4.72 lb VOC vapor released per dryer change
Dryer changes occur every 48 hours. The number of dryer changes is estimated to be 147
HFP vented = %HFP x lb of VOC per dryer change x number of dryer changes in the year= 347 lb HFP

Additional HFPO is emitted from the decontamination of hoses after each HFPO ISO is loaded.
The decontamination involves venting the contents of the two hoses to the WGS via a service manifold.
The liquid hose is 1" diameter x 20 feet long. The vapor hose is 0.5' diameter x 20 feet long. (BPF 346333).
Volume of liquid hose = 188.5 in = 3.09 L
Volume of vapor hose= 47.124 in3 = 0.77 L
The density of HFPO liquid at -25C is 1.58 kg/L Determined from physical property data
The density of HFPO vapor at -25C is 0.0563 kg/L Determined by ideal gas law @ -25C and max press of 700 kPa abs.
(max pressure observed H10765PG on iso container, after filling)
HFPO vented from Liquid Hose: (assumes hose volume is filled with liquid
Volume of hose X liquid density = I 4.88 kg from Liquid Hose
HFPO vented from Vapor Hose: (assumes hose volume is filled with va or)

I. Equipment Emissions
Equipment Emissions 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 emission types are as
follows: Equipment Emissions (EE) inside buildings = Stack Emissions (SE)
Equipment Emissions (EE) outside buildings = Equipment Fugitive Emissions (FE)
Maintenance Fugitive Emissions (ME)

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 lb emission/368 lb benzene used
Calculations:
Benzene introduced to process:
Benzene emissions:
560.228571 Ibs
560.23 Ibs
x 1.90 lb emission = 2.89 lb benzene emission
368 lb 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 month ('User E
Toluene added to process:
Toluene inventory in process as of last day of month ('Use

2015 AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION
Emission Source ID No: NS-B
Emission Source Description: VE-North PSEPVE Manufacturing Process
Process & Emission Description: The VE-North PSEPVE manufacturing process is a continuous chemical
reaction. All emissions from the process are vented through the Nafion Division Waste Gas Scrubber (Control
Device lD No. NCD-Hdr) which has a documented control efficiency of 99.6% for all acid fluoride compounds.
Some emitted compounds are assumed to pass completely through the scrubber, so the control efficiency for
those compounds is assumed to be 0%. The control of emissions of specific compounds will be addressed and
detailed in the following pages.
The PSEPVE process in VE-North emits compounds in the acid fluoride family. In the presence of water (such
as in atmospheric moisture), these acid fluorides can eventually hydrolyze to hydrogen fluoride. For the purpose
of this emissions inventory, a conservative approach will be taken and the acid fluorides will be reported both as
a VOC and as the equivalent quantity of hydrogen fluoride.
Basis and Assumptions:
- The PSEPVE 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.

The estimated HF equivalent emissions were determined by multiplying the total emission quantity of an acid
fluoride by the ratio of the molecular weight of HF divided by the molecular weight of the specific acid fluoride.
This is based on the fact that one mole of an acid fluoride will generate one mole of HF.
For example, if 100 lb. of PPF was emitted:
20 lb/mol HF
166 lb/mol PPF
X 100 lb/yr Equipment PPF
= 12.0 lb/yr HF

Emission Source ID No: NS-B
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 through the Nafton Division Waste Gas Scrubber
(Control Device lD No. NCD-Hdr) which has a documented control efficiency of 99.1% for all acid fluoride
compounds. Some emitted compounds are assumed to pass completely through the scrubber, so the control
efficiency for those compounds is assumed to be 0%. The control of emissions of specific compounds will
be addressed and detailed in the following pages.
The PPVE process in VE-North emits compounds in the acid fluoride family. In the presence of water (such
as in atmospheric moisture), these acid fluorides can eventually hydrolyze to hydrogen fluoride. For the
purpose of this emissions inventory, a conservative approach will be taken and the acid fluorides will be
reported both as a VOC and as the equivalent quantity of hydrogen fluoride.
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.

The estimated HF equivalent emissions were determined by multiplying the total emission quantity of an acid
fluoride by the ratio of the molecular weight of HF divided by the molecular weight of the specific acid
fluoride. This is based on the fact that one mole of an acid fluoride will generate one mole of HF,
For example, if 100 lb. of PPF was emitted:
20 lb/mol HF X 100 lb/yr Equipment PPF
166 lb/mol PPF

Emission Source ID No: NS-B
Emission Source Description: VE-North EVE Manufacturing Process
Vinyl Ethers North (NS-B)
EVE Process Emissions
Page 1 of 13
Process & Emission Description: The VE-North EVE manufacturing process is a continuous chemical reaction.
All emissions from the process are vented through the Nafion Division Waste Gas Scrubber (Control Device 1D No.
NCD-Hdr) which has a documented control efficiency of 99.1 % for all acid fluoride compounds. Some emitted
compounds are assumed to pass completely through the scrubber, so the control efficiency for those compounds is
assumed to be 0%. The control of emissions of specific compounds will be addressed and detailed in the following
pages.
The EVE process in VE-North emits compounds in the acid fluoride family. In the presence of water (such as in
atmospheric moisture), these acid fluorides can eventually hydrolyze to hydrogen fluoride. For the purpose of this
emissions inventory, a conservative approach will be taken and the acid fluorides will be reported both as a VOC and
as the equivalent quantity of hydrogen fluoride.
Basis and Assumptions:
- The EVE 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.

The estimated HF equivalent emissions were determined by multiplying the total emission quantity of an
acid fluoride by the ratio of the molecular weight of HF divided by the molecular weight of the specific
acid fluoride. This is based on the fact that one mole of an acid fluoride will generate one mole of HF.
For example, if 100 lb. of MAE was emitted:
20 lb/mol HF X 100 lb/yr Equipment MAE = 6.0 lb/yr HF
332 lb/mol MAE

Page 1 of 4
2015 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 division waste gas scrubber. 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.
Therfore the average molecular weight for condensation is 354
(g) average MW for non-acid fluoride component = 166 (average of HFPO & HFP)
(h) number of deinventory events = 7

2015 Equipment Emissions Determination
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 division scrubber efficiency is 99.6% for control of acid fluorides.

Emission Source Description: VE-South PEVE / PMVE Manufacturing Process
Process & Emission Description: The VE-South PEPM manufacturing process is a continuous chemical reaction. All
emissions from the process are vented through the VE-South Waste Gas Scrubber (Control Device ID No. NCD-Hdr2) which has
a documented control efficiency of 99.6% for all acid fluoride compounds. Some emitted compounds are assumed to pass
completely through the scrubber, so the control efficiency for those compounds is assumed to be 0%. The control of emissions of
specific compounds will be addressed and detailed in the following pages.
The PEPM process in VE-South emits compounds in the acid fluoride family. In the presence of water (such as in atmospheric
moisture), these acid fluorides can eventually hydrolyze to hydrogen fluoride. For the purpose of this emissions inventory, a
conservative approach will be taken and the acid fluorides will be reported both as a VOC and as the equivalent quantity of
hydrogen fluoride.
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:

A. Carbonyl Fluoride (COF2) CAS No. 353-50-4
HF Potential:
Each mole of COF2 (MW = 66) can generate 2 moles of HF (MW = 20).
F1kgCOF2 .1 moleCOF 20 g HF 2 molesHF — 0.606 kg H
66 g COF 1 moleHF 1 moleCOF
Therefore, each kg of COF2 generates 0.606 kg HF
Quantity Generated
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 275,769 kg PMVE produced
153,061 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 = 61.85 kg/h average precursor feed, (1066FC)
X 5992 hours of operation (from uptime data)
X 55% typical COF2 in precursor feed to PAF column
203,833 kg COF2 fed to PAF column
COF2 vented from PAF column = 203,833 153,061 = 50,772 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 275,769 kg PMVE produced
COF2 vented from condensation = 16,315

Fugitive Emissions
Page 1 of 4
Fugitive Emissions (FE) are a function of the number of emission points in the plant (valves, flanges, pump seals). For
the fugitive emission calculations the inventory shown below is conservative and based on plant and process
diagrams.
Note that the division scrubber efficiency is 99.6% for control of acid fluorides.
A. Fugitive Emissions from Condensation Reactor System
Condensation Tower (vents to stack
Valve emissions: 322 valves x 0.00039 Ib/hr/valve = 0.126 Ib/hr VOC from FE
Flange emissions: 644 flanges x 0.00018 Ib/hr/flange = 0.116 Ib/hr VOC from FE
Pump emissions: 6 pump x 0.00115 Ib/hr/pump = 0.007 Ib/hr VOC from FE
Total fugitive emission rate = 0.248 Ib/hr VOC from FE
Condensation Tower VOC

No normal process vents of AN to stack. Equipment emissions are estimated above for normal process composition and
leaks.
A material balance is also done to ensure all AN losses are accounted for. When material balance shows negative loss,
only the estimated equipment emissions are included.

x (1-(.05))
12,768 kg AN to H/C waste
13,440 kg AN fed

Note: Based on this material balance, it is assumed that no AN is emitted to atmosphere from fugitive emissions, other than
what is determined above.
The amount of hydrocarbon sent to waste is probably overestimated due to inaccuracies in calculation of VE-N portion of the
waste.

2015 Air Emissions Inventory Supoorting Documentation
Emission Source ID No.: NS-D
Emission Source Description: Nation RSU Process
Process and Emission Description:
The RSU process is a continuous manufacturing process. All emissions from this process vent to
the Nafion Division Waste Gas Scrubber (WGS),Control Device ID No. NCD-Hdrl, which has a
documented efficiency of 99.6%. The control of emissions of certain compounds will be
addressed in the attached spreadsheet. Certain components (i.e. TFE) pass completely through
the scrubber, therefore the efficiency is assumed to be 0%.
Basis and Assumptions:
The RSU process flowsheet 44 (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:

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
occured 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.

Fugitive Emission Determination
Page 1 of 2
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 5U Reactor, Rearranger, R5U 5till and R5U 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/flang, = 0.045 Ib/hr EE
Total equipment emission rate = 0.135 Ib/hr EE
Days of operation = 75
On average 0.13 Ibs of HF are produced for every 1 lb of RSU, SU or PAF.
VOC: 0.135 Ib/hr EE HF: 0.135 Ib/hr EE
x 24 hours/day x 24 hours/day
x 75 days/year x 75 days/year
242.4 Ib/yr VOC from EE x U.13 lb FIF per lb VOU
31.5 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/flang, = 0.032 Ib/hr FE
Total fugitive emission rate = 0.063 Ib/hr FE
S03: 0.063 lb. FE/hr H2SO4: 0.063 lb. FE/hr
x 24 hours/day x 24 hours/day
x 75 days/year x 75 days/year
113.4 Ib/yr S03 from EE x 1.225 lb H2SO4 per lb S03
= 138.9 Ib/yr H2SO4 from FE
C. Fugitive Emissions From EDC Tank
This equipment is not inside a building, therefore emissions are true Fugitive Emissions
Valve emissions: 20 valves x 0.00036 Ib/hr/valve = 0.007 Ib/hr FE
Flange emissions: 10 flanges x 0.00018 Ib/hr/flange = 0.002 Ib/hr FE
Total fugitive emission rate = 0.009 Ib/hr FE
VOC: 0.009 Ib/hr FE HF:

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.
Example: The TFE equipment emissions were determined by the ratio of the
TFE stack emission (1,997.9 lb) divided by the total stack emission (2,010.8 lb),
multiplied by the total equipment emissions (229.4 lb).
Specifically: 3500.0 242.4 = 240.8 lb. TFE

The Nafion 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 Nafion Division Waste Gas Scrubber
(Control Device ID No. NCD-Hdrl) which has a documented control efficiency of 99.6%
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 Division WGS. 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. See chart below.

The VOC emissions from the Waste Liquid Stabilization process is assumed to be comprised
of 30% by weight of COF2 and 70% by weight of TAF. The emission of these compounds
from each of the following events is determined simply by multiplying the total emitted VOC
by 30% to determine the COF2 emission and 70% to determine the TAF emission.

Stack Emissions from Maintenance Activity or Emergency Activity
for the Storage Tank
Background
Before performing maintenance on the reactor or storage tank, the pressure from the system
is vented to the Division WGS. 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. See chart below.

Sample calculation using maintenance activity dated 9/18/15
Initial Weight minus Final Weight equals kg vented to Division WGS
231 kg minus 143 kg equals 88 kg vented to WGS
Assume that all of the above is VOC emissions This assumption also overstates the true emissions
as inerts, such as nitrogen are not counted.
After -control emissions utilizing the 99.6% control efficient Waste Gas Scrubber (WGS):
Percentage of acid fluoride VOCs removed by the WGS = 99.6%
Percentage of acid fluoride VOCs vented from the WGS = 100% minus 99.6%
Percentage of acid fluoride VOCs vented from the WGS = 0.4%
Therefore, VOCs vented to the atmosphere from the 9/18/15 maintenance activity is equal to:
Amount of VOCs vented to WGS: 88 kg of VOC
Percentage of VOCs vented from the WGS: x 0.4%
Quantity of VOCs vented from the WGS: = 0.352 kg VOC
= 0.776019 lb VOC

MMF Process Fugitive / Equipment Emissions
Page 1 of 2
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 the following: (1) equipment
emissions not inside buildings, which are "fugitive" in nature and will be reported as such, and
(2) equipment emissiion 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: 552 valves x 0.00036 Ib/hr/valve = 0.199 Ib/hr EE
Flange emissions: 100 flanges x 0.00018 Ib/hr/flange = 0.018 Ib/hr EE
Total equipment emission rate = r
Days of operation = 38
On average 0.13 Ibs of HF are produced for every 1 pound of process material released
VOC: 0.217 Ib/hr EE HF: 0.217 Ib/hr EE
x 24 hours/day x 24 hours/day
x 38 days/year x 38 days/year
= 197.6 Ib/yr VOC from EE x 0.13 lb HF per lb VOC
= 25.7 Ib/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: 88 valves x 0.00036 Ib/hr/valve = 0.032 Ib/hr FE
Flange emissions: 10 flanges x 0.00018 Ib/hr/flange = 0.002 Ib/hr FE
Total fugitive emission rate = 0.033 Ib/hr FE
VOC: 0.033 lb. FE/hr HF:
x 24 hours/day
x 38 days/year
= 30.5 Ib/yr VOC from EE
0.033 lb. FE/hr
x 24 hours/day

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.
Example: The DMC equipment emissions were determined by the ratio of the
DMC stack emission (254.7 lb) divided by the total stack emission (306.7 lb),
multiplied by the total equipment emissions (358.9 lb).
Specifically: 168.7 197.E = 164.1 lb. DMC

Nafion E-Fluids Production Process
The E2 process is a batch manufacturing process. All emissions from this process
vent to the atmosphere, some via a vertical stack. The control of emissions of
certain compounds will be addressed in the attached spreadsheet.
Basis and Assumptions:
Engineering calculations using compositions, volumes and paritial pressures are used
to determine amounts vented. See attached information for assumptions made for
each vessel.
Information Inputs and Source of Info.:
Information Input
Source of Inputs
E2 production quantity
E2 Production Facilitator
Speciated emission rates
Attached calculations
Point Source Emissions Determination:
Point source emissions for individual components are given in the attached
spreadsheet
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.

Background
Three vessels inside the E2 Building vent to the E2 Bldg. stack (EP-NEP-1). The vessels are the Transfer
Tank, Interface Tank and a polypropylene 55 gal. drum. The crude E-fluids tote is filled on the outside on the
E2 building, therefore vented emissions from this tote are true "Fugitive Emissions" and will be reported as
such.
A. Transfer Tank
The Transfer tank is a 150 gallon vessel that is filled at a rate of 7.3 gal/min. The operating temperature
during the filling is 40 degrees C. The tank is filled with 125 gallons of material. We will assume that entire
tank volume (20 ft) is vented on filling.
Calculations:
PV = nRT (assumes the Ideal Gas Law)
Tank Volume = 150 gallons / 7.48 gal/ft3 = 20.05 ft3

Fugitive/Equipment Emissions
Page 1 of 2
Fuaitive 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 equpiment 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.
Calculations:
PV = nRT (assumes the Ideal Gas Law)
33% Tote Volume = 60 gallons / 7.48 gal/ft3 = 8.02 ft3

The emission rates for valves, flanges, etc. have been established by the DuPont Company. The emission
rates from these types of equipment in the E-fluids process is considered "Excellent' and therefore the

TFE / CO2 Separation Process (NS-M)
Page 1 of 1 f
2015 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 either the Nafion Division Waste Gas Scrubber (WGS) or the area vent stack. The control of
emissions of the TFE compound will be addressed in the attached spreadsheet. TFE will pass
completely through the scrubber, therefore the efficiency is assumed to be 0%.
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.

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.

HFPO Product Container Decontamination Process
HFPO product containers returned from customers are decontaminated by venting residual
hexafluoropropylene oxide ("HFPO") to the Nafion Division Waste Gas Scrubber (WGS). To
determine the amount emitted from this process, the vapor density of HFPO is used along with the
volume of the container.
Vapor density is based on Aspen process simulation data at 13°C, which is 0.0377 kg/L.
130C 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 ISO containers and ton
cylinders, i.e. where containers are emptied. (determined from www.worldcli mate. com).
The mass of vapor in a container emptied of liquid is equal to the volume of the container multiplied by
the vapor density.
Mvap = V Nap
Volumes of the containers currently in use are as follows:

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.

Emission Source Description: Vinyl Ethers North (VE-N) Product Container
Decontamination Process
Container Emission Estimation Basis:
Dimer, PPVE, PSPEVE and EVE are the products that are produced in the VEN facility. Usually
only PPVE is shipped to customers in 1-ton cylinders from the VE Nouth Manufacturing
Process. Prior to filling the containers, they are decontaminated by pressurizing with Nitrogren,
venting to the Waste Gas Scrubber (WGS) and evacuating for numerous cycles. TA NF-11-1821
has been written to fill on top of heels in cylinders without the need to decontaminate. This will
greatly reduce the emissions as a result of decontaminating product shipping containers. This
reduction should be reflected in the 2012 VE-N product container emissions report
To determine the amount emitted from this process, the vapor density of each component is used
along with the volume of the container.
Approximately 50°F (10°C) average year round temperature for Parkersburg, WV where
containters are emptied (use this temperature as worse case for all products). Assume when
containers are emptied they remain full of vapors.
All emissions from the process are vented through the Nafion Division Waste Gas Scrubber
(Control Device ID No. NCD-Hdr) which has a documented control efficiency of 99.6% for all
acid fluoride compounds. Dimer is an acid fluoride.
Vapor density is based on data from PM Report #231, PM Report PM-E-487 extrapolated to
10°C and the ideal gas equation.

Vinyl Ethers South(VE-S) Product Container
Emission Source Description: Decontamination Process
Container Emission Estimation Basis:
PMVE, PEVE and PPVE are the products that are shipped to customers in 1-ton cylinders,
413W cylinders, 4BA/3AA cylinders and ISO tank containers from the VE South
Manufacturing Process. Prior to filling the containers, they are decontaminated by
pressurizing with Nitrogren, venting to the Waste Gas Scrubber(WGS) and evacuating for
numerous cycles. TA's(NF-09-1737 & NF-11-1821) have been written to fill on top of heels
in ISO containers as well as cylinders without the need to decontaminate. This will greatly
reduce the emissions as a result of decontaminating product shipping containers. This
reduction should be reflected in the 2012 VE-S product container emissions report
It is assumed that the product split between PMVE and PEVE is 70 to 30 by weight and
remains unchanged. PPVE is produced very infrequently in VE-S and is not used in the max
to emit calculations shown below.
It is assumed that the container split between cylinders and ISO's remains unchanged. For
PMVE, 48% to Iso and 52% to ton cylinders. Assume all PEVE is placed into 1 ton cylinders
At design capacity rates of the VE South Manufacturing Process, a maximum of 1,500 kg per
day at 70%/30% PM/PE split can be produced. For 365 operating days per year and 100%
uptime(worse case), this equates to 383,250 kgs of PMVE and 164,250 kgs of PEVE.
Approx. 50°F(101C) average year round temperature for Dordrecht Plant in the
Netherlands,where PMVE ISO containers are emptied(use this temp as worse case for all
products). Assume when containers are emptied they remain full of vapors. Vapor density
for PMVE at this temp is 0.2258 lb/gal and for PEVE 0.0901 lb/gal. These densities were
computed using the Peng-Robinson modification of the Redlich-Kwong equation of state.
Iso volume is 4,480 gallons. 1 ton container volume is 200 gallons
To calculate the amount of product vented per container, the container volume is multiplied
by the vapor density

Development of Average Emission Factors and Baseline Emission Estimates for the
Industrial, Commercial, and Institutional Boilers and Process Heaters NESHAP, October
2002; so that figure is used as the latest information from EPA.
EPA emission factor = 7.1E-05 pounds of HCI per million BTUs generated in the boiler.
From the memo from Christy Burlew and Roy Oommen, Eastern Research Group to Jim
Eddinger, U.S. EPA, OAQPS, October, 2002, Development of Average Emission Factors
and Baseline Emission Estimates for the Industrial, Commercial, and Institutional Boilers
and Process Heaters National Emission Standard for Hazardous Air Pollutants, Appendix
A, the HCI emission factor for natural gas combustion is 1.24 x 10-5 lb. per MM-BTU.

HCI Emissions
Page 1 of 1
CAS No. 7647-01-0
The EPA Industrial Boiler MACT rulemaking emission factor for uncontrolled residual
and distillate oil firing is given as 7.1E-5 lb/MMBtu in Docket Document Number I1-13-8,
Development of Average Emission Factors and Baseline Emission Estimates for the
Industrial, Commercial, and Institutional Boilers and Process Heaters NESHAP, October
2002; so that figure is used as the latest information from EPA.
EPA emission factor = 7.1E-05 pounds of HCI per million BTUs generated in the boiler.
From the memo from Christy Burlew and Roy Oommen, Eastern Research Group to Jim
Eddinger, U.S. EPA, OAQPS, October, 2002, Development of Average Emission Factors
and Baseline Emission Estimates for the Industrial, Commercial, and Institutional Boilers
and Process Heaters National Emission Standard for Hazardous Air Pollutants, Appendix
A, the HCI emission factor for natural gas combustion is 1.24 x 10-5 lb. per MM-BTU.
Emission factor = 1.24E-05 pounds of HCI per million BTUs generated in the boiler.

Wastewater Treatment Plant (WTS-A)

2015 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 (WWTP) 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 volatilazation rate, thereby limiting the air emissions of
Basis and Assumptions:
The three major compounds that are treated in the WWTP are butyraldehyde, ethylene
glycol, and methanol.
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.
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.
Because of the above, it will be assumed that the WWTP 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 WWTP unit operation's emission factors
for butyraldehyde are twice as those for methanol.
The WWTP is fed 30% aqueous ammonia as a nutrient for the biological microbes.
Typically the WWTP consumes 69,000 lb/yr of this solution, which equates to 20,010 lb/yr
of 100% ammonia. To be conservative, the emissions of ammonia from the WWTP 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.

Note 1: Based on best professional judgement of Ken W. Cook, PE (DuET Wastewater Consultant)
the "Percent of compound biodegraded" was reduced from 94+% to 85% for the reports beginning
calendar year 2012. It is believed that an acclimated biological system would be able to biodegrade
85% of these simple organic compounds during the 18-hour residence period.

Ammonia (NH3) Emissions
The wastewater treatment plant ("WWTP") is fed aqueous ammonia (30% NH3) as a
nutrient for the biological microbes.
In 2015, the WWTP consumed 69,706 pounds of 30% aqueous ammonia, which equates to
20,912 pounds of 100% ammonia (100% NH3).
The aqueous ammonia is fed directly into the WWTP Aeration Tank that is aerated via
2,000 cubic feet per minute of diffused air injected into the bottom of the tank.
The aqueous ammonia is fed directly into the WWTP 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 WWTP will assume that none of the
NH3 is utilized by the microbes, who would convert the ammonia into nonvolatile nitrate.
The WWTP 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
quiessent 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 = 400.3 lb. NH3 / year
