(Contact, address, phone number changes entered into I-Beam/Facilities if necessary.
p' 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.
li' Evaluate "U" sources for significance and address according to policy.
C' Calculations / forms appear to add up correctly.
p' All compliance issues are being addressed (e.g. Toxics limits, above TV thresholds, large emissions increase/decrease, installation
without a permit).
p"All volatile HAPs/TAPs were included in the VOC total.
of 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.).
eReview facility comments and address any issues.
Update ED (Data Entry Main) if additional information is required (corrections due date and date received).
heck all ED QA/QC reports.
comparison with previous emission inventory must be made and outliers (> 10%) must be investigated and explained.

DAQ's Comments Regarding Inventory
CO, NOx, and PM emissions higher this year due to increased fuel used in boilers. CO emissions increase in boilers was
partially offset by a decrease in CO emissions from the perfluorinated vinyl ether process. S02 reduced due to error in
reporting of S02 emissions from the membrane coating process in 2012. Reported 1 ton S02 emissions, but process does
not emit S02. Toxics metals emissions increased due to higher fuel usages in boilers. VOC and general HAP emission
changes are due to changes in product throughputs for the various chemical processes at the facility. most of which emit
VOC.

Boiler PS -A
Hydrogen Chloride (HCI)
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 II-B-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.

Butyraldehyde Storage Tank
The Butyraldehyde (BA) Storage Tank is a vertical fixed dome roof storage tank. It is
maintained at a working level by re -filling from tank trucks or rail cars. The storage tank is
vented through a brine -cooled condenser (control device BCD -A) and a conservation vent to
the atmosphere.
Basis and Assumptions:
Estimated uncontrolCTanks)�4.
s from this unit (breathing and working losses) are calculated
using EPA-developesoftware. Actual working losses are zero because when
being loaded, the tank is vented back to the tank truck or railcar. Actual breathing losses are
reduced by the brine cooled condenser. Thus control on working losses is 100% and control
on breathing losses is 68%.
As shown by the calculations attached, this gives an overall control efficiency of
approximately 90%.
Fugitive emissions are calculated using the EPA SOCMI factors. Butyraldehyde is classified
as a light liquid.

Throughput for the BA Storage Tank in 2013 equaled 1,756,502 Storage Units ('SU').
Using the actual throughput and the working volume of the BA Storage Tank, there were 38.1 turnovers
of this tank during the year.
Entering this data into the TANKS 4.09d software, the following quantities of uncontrolled BA
emissions were returned:
Annual uncontrolled breathing loss =
1,460 pounds
Annual uncontrolled working loss =
366 pounds
Annual total uncontrolled emissions =
6,956 pounds
Average BA vapor pressure in tank =
1.424 psia
The condenser efficiency calculation assumes the condenser exit temperature is equal to the coolant
temperature of 32 ° F. The BA vapor pressure at 32 ° F equals 0.558 psia.
The condenser efficiency = [ 1 - (BA vapor pressure at 327 / average BA vapor pressure in tank) ] x 100
_ [ 1 - (0.558 psia / 1.424 psia) ] x 100
61% BA condensed back into the tank
Therefore, the actual breathing loss emissions through the condenser would be 39% of the uncontrolled breathing
loss coming into the condenser:
1,460 lb. BA X 39% = 572 lb. BA
year year
Since the BA Storage Tank is vented to the rail car or tank truck during unloading operations, there are zero

Emission Source Description: Butacite® Flake Reactors
Process & Emission Description:
The Butacite® Flake Reactors receive raw materials and react them to create a polyvinyl butyral ("PVB")
polymer dispersion. Polyvinyl alcohol ("PVA"), one of the two major reactants, contains up to 1% by
weight of methanol. Butyraldehyde ("BA"), a VOC, is the other major reactant. After the reaction step, the
reactor contents are sparged with nitrogen to remove unreacted BA. The PVB dispersion mix is then
pumped from the reactors for draining, washing with water, re -slurry and storage. Each reactor has a reflux
condenser, which in turn vent to one of two water scrubbers (control devices BCD-B 1 and BCD-132). The
residual methanol and unreacted BA which exit the reactor through the vent line are either condensed back
to the reactor or enter the water scrubber. That which is not removed in the scrubber is vented to the
atmosphere.
Basis and Assumptions:
Estimated uncontrolled methanol emissions from this operation are based on modeling of the individual
steps of the reactor batch process using commercial software called 'Emission Master". This software
incorporates the equations in the National Emission Standards for Pharmaceutical Production (40 CFR
63.1257) as required by the MON rule. Emissions results from this modeling were presented to the
NCDENR in our MON Notification of Compliance Status Report dated 10/2/2008.
Estimated uncontrolled butyraldehyde emissions from this operation are based on modeling of the
Butacite® PVB polymer production process using ASPEN Tech process modeling software. This process
model was developed by the DuPont Engineering Technology group in Wilmington, Delaware in May
2008.
Uncontrolled methanol emissions from the Butacite® reactors were calculated to be 1.448 x 10-4 lb. per
PVB polymer production unit ("PPU"). Uncontrolled butyraldehyde emissions from the Butacite® reactors
were calculated to be 2.279 x 10-2 lb. per PPU. These emissions are reduced by 99% through the scrubbers.
Fugitive emissions are calculated using the EPA SOCMI factors. Butyraldehyde is classified as a light
liquid.
Due to the small fraction of methanol in the vapor space, fugitive emissions are nil.

Butacite® Flake Dryer
The Butacite® Flake Dryer is a fluidized bed dryer which dries water from the wet
polyvinyl butyral ("PVB") flake. During normal operation of the Flake Dryer, some of the
solid PVB particles are entrained in the exit of the heated air stream of the dryer. The PVB
exiting the Flake Dryer is controlled by a cyclone separator that in turn discharges the air
stream to a fabric filter baghouse which vents to the atmosphere.
The wet PVB feed to the Dryer contains a small amount of methanol. Methanol is an
impurity in the polyvinyl alcohol ("PVA"), one of the major raw materials for the PVB.
The methanol entering with the wet PVB feed to the Dryer is that which remains following
the previous process steps of PVA dissolving, PVB reaction, PVB washing and re -slurry
and centrifuging. This methanol is vented from the Flake Dryer with the water during
drying of the PVB.
Basis and Assumptions:
The Butacite® Flake Dryer air exhaust vents to a cyclone separator with a 90% removal
efficiency for Total Suspended Particulates (TSP) which in turn vents to a bag filter house
with a 99% removal efficiency for TSP.The above stated control efficiencies are based on
efficiency test with the Flake Dryer running at full capacity. There are no fugitive
emissions.
All methanol entering the system is listed as point source emissions; therefore, there are no
fugitive emissions.

Point Source Emission Determination - Line 4 Extrusion Process Via Steam Jet Vacuum
Triethylene glycol di-2-ethylhexanoate
(3GO)
Emission Estimation Approach:
CAS No. 94-28-0
Emissions from the Butacite(V Line 4 Sheeting Extrusion Process (ID No. BS-E2) extruders
are calculated using a mass balance approach. Based on the vapor pressure exerted by organic
material in the extruder and the flow rate out of the extruder, material flowrates throughout
the entire extruder process are calculated. There are a total of four (4) extruders in the Line 4
extruder operation. The final condenser (BCD-E2) vents to the atmosphere through its vent
stack (BEP-E2).
The current Line 4 sheeting extrusion process consists of the extruder unit followed by a
knock -out pot, and the steam jet vacuum system. Material flowrates into and out of each of
these process steps are calculated below.
General Steps for Quantifying Emissions:
The primary purpose of the extruders is to remove water from the extruder feed material. This
is accomplished by heating the feed material and operating the extruders under vacuum
conditions. A vacuum is pulled on each extruder via a 2-stage steam jet vacuum system. The
vacuum jet system consists of a 1st condenser followed by the 1st vacuum jet, 2nd condenser,
2nd vacuum jet, and lastly a final condenser. The purpose of the first condenser is to remove
condensable substances so as to maximize efficiency of the steam jet. The purpose of the 2nd
condenser is to condense steam injected into the 1st vacuum jet in order to maximize
efficiency of the 2nd vacuum jet. The purpose of the final condenser is to condense the steam
that is injected into the 2nd vacuum jet. The general steps for quantifying emissions are as
follows:
STEP 1: Estimate the VOC's vented from the extruder unit based on the water and
noncondensables that are vented, the total system pressure, and the approximate vapor
pressure of organics.
STEP 2: Calculate the amount of VOC that passes through the first condenser based on the
temperature out of the first condenser, the noncondensable flow, and the system pressure.
STEP 3: Calculate the amount of VOC that passes through the second condenser based on
the temperature of the second condenser, the noncondensable flow, and the system pressure.
DEQ-CFW 00068608

STEP 4: Calculate the amount of VOC that passes through the final condenser based on the
temperature of the final condenser, the noncondensable flow, and the atmospheric pressure.
For Steps 1 and 2, the VOC flowrates are calculated on a per extruder basis. For Steps 3 and
4, the VOC flowrates are calculated per extruder and for all four extruders combined.

1 The organic vapor pressure is based on a plasticizer which is added to the polyvinyl
butyral (PVB) product. This plasticizer is called "3GO" and is Triethylene Glycol di-2-
ethylhexanoate which has a molecular weight of 402.6 lb/lb-mole. The Butacite® product
contains approximately 28% 3GO. As is normally the case for compounds with high
molecular weights, 3GO has an extremely low vapor pressure. Other materials are added
to PVB to give it various properties; however all of these materials have negligible vapor
pressures and are added in very small amounts (0.1 % or less). Therefore, all organic
emissions are assumed to be 3GO. According to EPA literature, the vapor pressure of
3GO is 0.00000422 mmHg at 25 °C and 5 mmHg at 219 *C. Extrapolating, the vapor
pressures of 3GO would be 0.26 mmHg at 35 °C and 3.22 mmHg at 150'C.
These vapor pressure values are conservative because it is expected that they overestimate
actual vapor pressures primarily because they do not account for mole fractions in the
extruder feed (i.e. Raoult's Law), and furthermore, they do not account for molecular level
interactions that resist volatilization (this is why all of the water is not removed even
though the extruders operate in excess of the atmospheric boiling point temperature of
0 water and under vacuum).

Note: Much of the VOC in the extruder off -gas is expected to be captured in the knock -out
pot. However, for the purposes of these calculations, it is assumed that all of the VOC enters
into the 1 st condenser.
All of the noncondensables pass through the first condenser. Most of the water and most of
the VOC are condensed. The vapor pressure of water and VOC at the condenser outlet are
used to calculate their overall mole fraction. Based on this and the known moles of
noncondensables passing through the condenser, the mass of VOC and water passing through
the condenser is calculated.

In general the same approach used in Steps 2 and 3 is applied here with the only difference
being that the system pressure is atmospheric at the condenser outlet which results in a lower
VOC mole fraction.

Point Source Emission Determination - Butacite® Line 4 Back -End Process
The Butacite® Line 4 Back -End Process (ID No. BS-E4) consists of the Quench Tank, the
Dryer/Relaxer, and the Wind -Up Area. All air emissions associated with this equipment are
vented uncontrolled through the Butacite® Manufacturing Building main stack (BEP-3).
The estimation of VOC emissions from the Butacite® Line 4 Back -End Process is based on the
conservative engineering calculations shown in the May 7, 2002 addendum to the Title V Air
Permit application. The worst -case conservative assumption, which results in the highest
potential emissions, is that all of the emissions from the sheeting process are the plasticizer
(triethylene glycol di-2-ethylhexanoate or 3GO, CAS Number 94-28-0). Those calculations are

Emission Source Description: PVA Unloading System and Storage Silos
Process & Emission Description:
Polyvinyl alcohol (PVA) is unloaded from rail cars into one of two storage silos using a
pneumatic conveying system. The PVA contains up to 1 percent methanol. During
unloading and storage, some of the methanol is emitted due to outgassing from the PVA. A
portion of the methanol is emitted at the unloading blower discharge and the remainder is
emitted through the conservation vents on the PVA silos, as the PVA displaces the vapor in
the silos.
Basis and Assumptions:
Estimated uncontrolled emissions from this operation are based on sampling of the methanol
concentration in the vapor space during unloading operations. Calculations supporting these
emissions were presented to the NCDENR in our MON Precompliance Report dated
11/8/2005 and in our MON Notification of Compliance Status Report dated 10/2/2008.
An engineering analysis was conducted in 2005 to determine the concentration of methanol
in the PVA unloading conveying air. Sampling of the unloading blower exhaust showed
methanol emissions to be 1.27 lbs per 1000 conveying units of PVA. In 2008, the methanol
weight fraction in the PVA was reduced from 1.2% to 1.0%. Therefore, assuming a linear
reduction in outgassing with the reduction in methanol concentration in the PVA, the
methanol emissions at the unloading blower exhaust were reduced to 1.059 lbs per 1000
conveying units of PVA.
In 2008, sampling of the vapor space above the stored PVA at equilibrium, as exists in the
PVA silos, showed the methanol emissions to be 0.138 lbs per 1000 conveying units of
PVA.

PVA Dissolver Tank System
Polyvinyl alcohol (PVA) is dissolved in a batch cycle, which begins by adding a weighed
amount of PVA powder and cold water into a small Pre -dissolver tank in the correct ratio.
This slurry is transferred to one of two Dissolver tanks where the mix is heated with live
steam in order to dissolve the PVA in the water. The solution is heated to 90 ° C and is then
transferred to a Holdup tank while awaiting transfer to the subsequent reaction step. Both
Dissolvers and the Holdup tank are vented to atmoshpere and have reflux condensers on
their vents. The PVA powder feed contains up to 1.0% methanol by weight. During the
Dissolver process, a fraction of the methanol is emitted through the tank's vents.
Basis and Assumptions:
Estimated uncontrolled emissions from this operation are based on modeling of the
individual steps of the Dissolver process using commercial software called "Emission
Master". This software incorporates the equations in the National Emission Standards for
Pharmaceutical Production (40 CFR 63.1257) as required by the MON rule. Emissions
results from this modeling were presented to the NCDENR in our MON Notification of
Compliance Status Report dated 10/2/2008.
Methanol emissions from the Dissolver process were calculated to be 1.123 lb./operating
time unit ("TU") based on continuous operation of all Dissolver process steps. This is a
conservative approach since the Dissolver process is a batch operation. In determining
actual operating time for this system, the system is considered to be operating unless both
Dissolver Tanks have been empty for greater than 8 hours.
Fugitive emissions of methanol are assumed to be nil and are not calculated.

C. Acid Fluoride Solvent - mixture of TAF and TFF
Perfluoro-3,5,7,9,11-pentaoxadodecanoyl fluoride (TFF)
Trifluoromethyl ester of carbonofluorldic 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
330 lb TAF 1 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.
Most TFF is believed to be of chain length less than n=4 based on recent analysis.
[ 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 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.

The amount of piping involved in the decontamination is negligible (isolation valves are in close proximity to hoses).
Total HFPO from decontamination of loading hoses = Number of events' (vented from liquid hose + vapor hose)
= 37 X 4.92 = 182 kg HFPO

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)
A. Equipment Emissions Inside Buildings (Stack Emissions)
1. Equipment Emissions (EE) from Barricade:
Emissions are vented from equipment located in the barricade and are vented through the barricade scrubber. Barricade
scrubber is 95% efficient for control of acid fluorides. From ASPEN Model:

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:

Emission Source ID No: NS-B
Emission Source Description: VE-North EVE Manufacturing Process
EVE Process Emissions
Page Iof13
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 ID 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 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
332 lb/mol MAE
X 100 lb/yr Equipment MAE
= 6.0 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 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. 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 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 ID 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

0 2013 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 67% acid fluorides and 33% 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 351
(g) average MW for non-acid fluoride component = 166 (average of HFPO & HFP)
(h) number of deinventory events = 9

2013 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 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 comppounds 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 flowshect is available wider 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:

Point Source Emissions Determination
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).
1 moleCOF HF 20 g HF 2 moles
1 kg COF2. = 0.606 kg HF
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 262,090 kg PMVE produced
145,469 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 = 55.22 kg/h average precursor feed, (1066FC)
X 6235 hours of operation (from uptime data)
X 55% typical COF2 in precursor feed to PAF column
189,363 kg COF2 fed to PAF column
COF2 vented from PAF column = 189,363 145,469 = 43,894 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
kg PMVE produced
X 262,090 kg PMVE produced
COF2 vented from condensation = 15,505
Total COF2 vented from process vents to WGS = 43,894 + 15,505 = 59,400 kg
After -control emissions utilizing the 99.6% control efficient Waste Gas Scrubber (WGS)
VOC emissions: 59,400 kg COF2 emitted to WGS
x (100% - 99.6%)
238 kg VOC = 238 kg VOC

PAF 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
PAF in feed to condensation to the overall amount of PEVE produced:
kg PAF in Condensation feed = 0.716
kg PEVE produced
X 108,518 kg PEVE produced
77,663 kg PAF fed to condensation
PAF vented from PAF column is determined from a material balance on the column:
PAF vented from PAF column = PAF fed to PAF column - PAF fed to condensation
PAF fed to PAF column = 55.22 kg/h average precursor feed, (1066FC)
X 6235 hours of operation (from uptime data)
X 44% typical PAF in precursor feed to PAF column
151,491 kg PAF fed to PAF column
PAF vented from PAF column = 151,491 77,663 = 73,828 kg
PAF vented from condensation (primarily the reactor vent) will also vary with product split, and is therefore estimated using
a relationship from the flowsheet:
kg PAF vented = 0.044
kg PEVE produced
X 108,518 kg PEVE produced
PAF vented from condensation = 4,775
Total PAF vented from process vents to WGS = 73,828 + 4,775 = 78,603 kg

Emission Source ID No: NS-C
Emission Source Description: VE-South PPVE Manufacturing Process
PPVE Emissions
Page 1 of 2
Process & Emission Description: The VE-South PPVE manufacturing process is a continuous
chemical reaction. All emissions from the process are vented through the VES 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 PPVE 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:
- 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.

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:
4.0 lb. PPF 20.006 lb. HF per mole HF 0.5 lb. HF

2013 Fugitive Emissions Determination
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.

2013 Air Emissions Inventory Supoorting 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 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 #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
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.

RSU Process
Fugitive and Equipment Emissions Determination (Non -point Source):
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 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
Flange emissions: 550 flanges x 0.00018 Ib/hr/flange
Total equipment emission rate
Days of operation = 82
0.090 Ib/hr EE
0.045 Ib/hr EE
0.135 Ib/hr EE
On average 0.13 Ibs of HF are produced for every 1 Ib of RSU, SU or PAF.
VOC: 0.135 Ib/hr EE
x 24 hours/day
x 82 days/year
= 265.0 Ib/yr VOC from EE
HF: 0.135 Ib/hr EE
x 24 hours/day
x 82 days/year
x 0.13 Ib HF per Ib VOC
34.4 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. 000 18 Ib/hr/flange = 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 82 days/year x 82 days/year
124.0 Ib/yr S03 from EE x 1.225 Ib H2SO4 per Ib S03
= 151.9 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

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: 2835.8 265.0 = 263.3 lb. TFE

Nafion Liquid Waste Stabilization
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.

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 9/18/13 maintenance activity is equal to:
Amount of VOCs vented to WGS: 44 kg of VOC
Percentage of VOCs vented from the WGS: x 0.4%
Quantity of VOCs vented from the WGS: = 0.176 kg VOC

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.

kg vented to Division WGS
32 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 9/17/13 maintenance activity is equal to:
Amount of VOCs vented to WGS: 32 kg of VOC
Percentage of VOCs vented from the WGS: x 0.4%
Quantity of VOCs vented from the WGS: = 0.128 kg VOC
= 0.282189 lb VOC

2013 Air Emissions Inventory Supporting Documentation
Emission Source ID No.: NS-F
Emission Source Description: Nafion MMF Process
Process and Emission Description:
The MMh' process is a batch/semi-batch 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 following spreadsheets. Some
compounds (i.e. TFE) pass completely through the scrubber, therefore the efficiency is
assumed to be zero percent (0%).
Basis and Assumptions:
The MMF process flowsheets #9599 and #5600 are used as a basis for relative
compositions and flow rates of vent streams to the division WGS.
Information Inputs and Source of Inputs:
Information Input
Source of Inputs
MMF production quantity
MMF Production Facilitator
Speciated emission rates
MMF Process Flowsheets
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 seperate section of this supporting documentation.

MMF Process Fugitive / Equipment Emissions
Page 1 of 2
I* Fugitive and Eauipment 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
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 = 44
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 44 days/year x 44 days/year
= 228.9 Ib/yr VOC from EE x 0.13 lb HF per lb VOG
= 29.8 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: 0.033 lb. FE/hr
x 24 hours/day x 24 hours/day
x 44 days/year x 44 days/year
= 36.4 Ib/yr VOC from EE x 0.13 lb 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.
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: 203.7 228.9 = 190.1 lb. DMC

Emission Source Description:
Process and Emission Description:
NS-K
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
7
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.

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.

NS-N HFPO Decontamination
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 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.worldclimate.com).
The mass of vapor in a container emptied of liquid is equal to the volume of the container multiplied by
the vapor density.

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.

Four 1-Ton cylinders of HFPO were returned from 3M. The cylinders came back high in
HFA according to the sample analysis sheet sent by 3M. Although only 3 cylinders were
liquid full with a weight of 1800 Ibs, we assumed that all 4 are liquid full to give the most
conservative estimate possible. Additionally, we assumed that all material was vented
and that none was removed by the Waste Gas Scrubber during decontamination to
further provide a conservative estimate. Based on the analytical results provided by 3M,
and the above assumptions, the total amount of HFPO and HFA vented was calculated
and is added manually to the Summary report total. Total for all 4 cylinders is 4939 Ib

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 Nouh 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(10°C) 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

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 Henrys 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.
DEQ-CFW 00068787

•
•
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 29% 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 (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% these simple organic
compounds during the 18-hour residence period.

Emission Source ID No.: WTS-A
Emission Source Description: Central Wastewater Treatment Plant
Ammonia (NH3) Emissions
The wastewater treatment plant ("WWTP") is fed 29% 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 ("NH3"). The NH3 is fed directly into the
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.

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 NH3 from the clarifiers would be a small fraction of
the estimated NH3 emissions from the Aeration Tank. To be conservative, it will be assumed
that the emissions of NH3 from the clarifiers are equal to the NH3 emissions from the Aeration
Tank.
Emission of NH3 from the WWTP Clarifiers = 383 lb NH3 / year
Total Emission of NH3 from the WWTP System (ID No. WT-A)
Emission of NH3 from the WWTP Aeration Tank = 383 lb NH3 / year

Supporting Documentation for WWTP Sludge 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:

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 for 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
in (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 = 0.0406 x ppmv x Molecular Weight
in
For example, converting 0.021 ppmv of methyl amine (MW = 31) to mg/m3 follows:
Is 0.0406 x 0.021 ppmv x 31 grams = 0.026 mg

Emission Source Description: SentryGlasO Process
Process and Emission Description:
The SentryGlasO Process is a continuous process in which solid resin is extruded into a
rigid sheet. There is no chemical reactions or processes associated with this process. The
solid resin is delivered to the site, where it and another solid powder are then mechanically
charged into the process. These solids are then extruded into the final sheeting. All air
emissions from this process result from the evolution of volatile compounds, which are
entrained in the resin, from the resin due to the heat of extrusion.
Basis and Assumptions:
The emission rates from the SentryGlasO Process is based on the emissions from a sister
manufacturing facility in Germany. For simplicity, the reported emissions are based solely
on the emissions from the process at full production design rates. This approach should
over -estimate the emissions, in part due to no credit being taken for the organics that would
be expected to solubilize in the water used in the liquid ring vacuum pump. Also note that
there is no control device associated with this process.

Emissions from the SentryGlas® Process are reported as Volatile Organic Compounds
("VOC"), Particulate Matter ("PM" and "TSP"), and in the case of methanol as a
Hazardous Air Pollutant ("HAP"). All emissions are based on the emissions at full design
rates.
Emissions of particulates from the SentryGlas® Process are discharged inside the
manufacturing building, thus there should be no emissions of particulate matter.
However, to be conservative, the emission of Tinuvin 328, a solid, will be reported as PM
emissions.
The emission rates from the SentryGlas® Process are based on the emissions from a
sister manufacturing facility. The reported emissions are based on the emissions from the
process at full production design rates, and are expressed as pounds of pollutant per Time

Polyvinyl Fluoride Process No. 1
ad 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-61 (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 installled 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-63 (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-B4 (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).

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-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

micron size, 88% for 1.0 - 3.0 micron size, and 99% for 3.0 - 10.0 micron size.
The second stage fabric filter or pre -separator is a TDC Filter SB-TX heavy-duty spunbond
100% synthetic filter media withhigh effiency ePTFE membrane applied. Its MERV Test
results shows the filter's efficiency for capturing / controlling particles is 99.99% for 0.3 -
1.0 micron size, 100% for 1.0 - 3.0 micron size, and 100% for 3.0 - 10.0 micron size.
The amount of PVF powder captured from the pre -separator is no more than two 340-1b.

Determination of before -control particulate matter is based on the conservative estimate of
8,160 lb/yr collected from the 1st -stage filter (pre -separator), the capture efficiencies of
that filter, and the particle size distribution of the PVF powder.
Results of particle size distribution testing of size batches of PVF powder during August
through October 2013 showed the worst -case situation of 68% being less than 1.0 µm. To
be conservative, it will be assumed that 70% of the PVF powder is less than 1.0 µm and
30% of the powder 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 annualized quantity of particulate emissions that is captured / controlled by the lst-
stage filter is 8,160 lb. per year and is equal to the following:

be conservative, it will be assumed that 70% of the PVF powder is less than 1.0 µm and
30% of the powder 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 annualized quantity of particulate emissions that is captured / controlled by the 1 st-
stage filter is 8,160 lb. per year and is equal to the following:

The annualized quantity of the 1st -stage filter's after -control particulate matter that passes
through the 1st -stage filter and enters the 2nd-stage filter as the uncontrolled particulate
matter for the 2nd-stage filter is:
13,600 lb. — 8,160 lb. = 5,440 lb.

Vendor literature from TDC Filter states the capture / control efficiency of their SB-TX
Filter Media is 99.99% for particles less than 1.0 µm and 100% for particles greater than
1.0 µm. To be conservative, it will be assumed the efficiency is 99.99% for all particles.
The annualized quantity of particulate emissions that is captured / controlled by the 2nd-
stage filter is:
5,440lb. X 99.99% = 5,439.5lb.
The annualized quantity of the 2nd-stage filter's after -control particulate matter that passes

Emission Source Description: Waste DMSO Storage Tank
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
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, a truck comes and disposes of the
DMSO solution. The tank is open to the atmosphere with a gooseneck pipe 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 DuPont Good Emission Factor on Equipment Leaks for fugitive emissions
(See Appendix A).
- Flange emissions were used for all equipment except valves and pumps.

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 (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.

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

Process and Emission Description:
The DuPont 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 in these spray booths is fairly frequent. Most of the painting is of the
the Fluoromonomer product cylinders. The basis of the emissions determination is the
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.

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

AIR EMISSIONS INVENTORY SUPPORTING DOCUMENTATION
Emission Source ID No.:
Emission Source Description:
Process Description:
Butacite® Plasticizer Storage Tank
This tank is used to store triethylene glycol bis (2-ethylhexanoate) or 3GO. Emissions from this
tank would be exclusively from the diurnal temperature change. Because the delivery railcar is
closed -loop vented with the tank, the displaced headspace associated with the unloading of the
railcar is vented back to the railcar, thereby resulting in no emissions to the atmosphere. The
tank vents to the atmosphere through a conservation vent, so there are normally no emissions
from the tank unless the tank is heating up from the sun.
Basis and Assumptions:
- Venting to atmosphere occurs only from daytime heating.
- Tank volume = 60,000 gallons or 8021 ft3
- 3GO vapor pressure = <0.0075 mm Hg @ 20°C (see Note 1)
5 mm Hg @ 219°C (see Note 2)
- Molar volume of an Ideal Gas @ 0°C and 1 atm = 359 ft3/(lb-mole)
- Molecular Weight of 3 GO = 403 (403 lb 3 GO / lb -mole 3 GO)
- Assume one complete tank volume turnover per day for point source emissions.
- Assume DuPont Good Emission Factor on Equipment Leaks for fugitive emissions
(See Appendix A).
- Flange emissions were used for all equipment except valves and pumps.

Point Source Emissions Determination:
Assume a diurnal temperature change from a nighttime low of 50°F (10°C or 283°K) to a
daytime high of 113°F (45°C or 318°K).
Assume the entire tank volume (8021 ft) is nitrogen saturated with 3GO.
Assume the ideal gas law applies:
Pressure x Volume = lb -moles x Gas Constant x Temperature
At a temperature of 10°C (510°R):
( 1 atm ) x (8021 ft) = ( n lb -moles) x ( 0.73 atm ft3 °R"1 lb-mole-1 x (510°R)
n lb -moles = 21.55 lb -moles of gas inside the tank
At a temperature of 45°C (573°R):
(1 atm ) x (8021 ft) = ( n lb -moles) x ( 0.73 atm ft3 °R"1 lb-mole-1 x (573°R)
n lb -moles = 19.18 lb -moles of gas inside the tank
Therefore, if the tank heats from 10°C to 45°C, then 2.37 lb -mole (21.55 minus 19.18) of gas per
day is lost through the conservation vent.
Vapor pressure of 3GO = <0.0075 mm Hg at 20°C
Mole fraction 3GO in vapor (using Dalton's law):
Mole fraction 3GO = Vapor pressure 3GO = 0.0075 mm Ha = 0.0000099 mole 3GO
Total pressure in tank 760 mm Hg mole gas in tank
Pounds of 3GO emissions from tank from diurnal temperature change:
2.37 lb -mole x 0.0000099 lb -mole 3GO x 403 lb 3GO = 0.0095 lb 3GO
day lb -mole gas in tank lb -mole 3GO day
Total 3GO emissions per year from the diurnal temperature change:
0.0095 lb 3GO x 365 days x 1 ton = 0.002 ton 3GO
day year 2000 lbs year

9 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 WAR 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 (CIA 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.
