Facility ID: 0900009, Fayetteville, Bladen County
Permit No. 03735T48
Dear Ms. Sands,
While evaluating a response to your March 27, 2020 email and Additional Information
Request letter to Chemours regarding the IXM Filmtruder permit application, Chemours
determined that the project had the capability of also increasing actual production in
other areas of the facility that were originally thought to be unchanged. Therefore, we
are resubmitting the permit application to address the potential emission increases in
other areas of the facility due to debottlenecking (see Attachment A). In addition,
Chemours is providing responses to your questions detailed in the Additional
Information Request letter received on March 27, 2020.
IXM Filmtruder
1. Question/Comment: Do the VOC emissions in form B include the new
filmtruder? Please fill in the emissions for this form, rather than an approximation
of emissions.
Response:An updated Form B for the new Filmtruder is included in Appendix A
of the enclosed revised Filmtruder permit application. The estimated emission
depicted on Form B include emissions from the new Filmtruder and existing
operations in NS-G Resins.
2. Question/Comment: The VOC emissions in Form C3 (0.21 Ib/hr) are lower than
the VOC emissions in the detailed emission calculation in Appendix C (10,717
Ib/yr which is equivalent to 1.22 Ib/hr); please clarify or correct.
Response: The value referenced from Appendix C (10,717 Ib/yr) included both
process and fugitive emissions. Appendix C has been updated as part of the
revised permit application. The emissions shown on Form C3 are from the
thermal oxidizer exhaust and include all sources vented to the thermal oxidizer.

3. Question/Comment: Form D5 is not signed
Response:An updated form D5 is included in Appendix A of the enclosed
revised Filmtruder permit application.
4. Question/Comment: Are the pieces of equipment in Appendix B just the new
equipment? Is it the polymerizer that is vented to the oxidizer?
Response—Appendix B of the revised Filmtruder application provides a diagram
of the existing and new equipment.
5. Question/Comment: Please provide sample calculations for HF and CO2 in
Appendix C.
Response:Attachment B includes sample calculations for the HF and CO2
generated by the thermal oxidizer and controlled by the scrubber from the new
IXM Filmtruder and existing equipment in NS-G Resins.
6. Question/Comment: In the THE calculation, where did the methanol
composition come from?
Response: The methanol composition used in the THE calculations were
obtained from the original MON determination submitted in 2005. The value is
assumed to be either from samples taken as part of the original MON
determination or from ASPEN modeling data. This project will not affect methanol
concentration in the recirculation tank; however, as discussed below that value
has been updated to be consistent with air emission inventory calculations.
7. Question/Comment: How does this compare to the data used in the forms and
emissions calculations?
Response: For the annual emission inventory, the composition of the methanol
in the vapor space was estimated based on the concentration of E2, PSEPVE
and methanol in the liquid composition. The vapor space composition of
methanol is estimated to be 57,000 ppmv. The THE calculations have been
recalculated using this value and are included as Appendix D to the revised
Filmtruder permit application.

Emissions from the IXM Resins Process (except Fluorinator) (ID No. NS-G-1)will be sent to the thermal
oxidizer/scrubber system (NCD-Q1/Q2). The thermal oxidizer will generate HF and CO2 emissions due to
combustion of the volatile organic compounds (VOC) in the vent stream. The thermal oxidizer will control
VOC emissions by 99.99%. The emissions from the thermal oxidizer are then vented to the scrubber,
which will control HF and CO2 emissions generated in the Thermal Oxidizer by 99.95%.
An example calculation showing the HF emissions generated from the destruction of Perfluoro(4-methyl-
3,6-dioxaoct-7-ene)sulfonyl fluoride(PSEPVE) emissions is shown below.

AIR PERMIT APPLICATION INTRODUCTION
Installation of Wiped Film Evaporator in IXM Resins Process
1. INTRODUCTION
The Chemours Corporation (Chemours) owns and operates a chemical manufacturing facility located at
22828 NC Highway 87 West, Fayetteville, Bladen County, North Carolina(Chemours Company—
Fayetteville Works, or the facility). The facility operates under Air Quality Permit 03735T48, effective on
12 July 2020 and expiring on 31 March 2021. The facility is a major source of criteria pollutants under the
Part 70 (Title V) Operating Permit Program and a major source of Hazardous Air Pollutants(HAPs).
Chemours is requesting authorization to construct an additional Wiped Film Evaporator(FilmtruderTM)to
be located in the IXM Resins Process area (ID No. NS-G-1). The new FilmtruderTM will allow for an
approximate 30% increase in IXM Resin Process production. The proposed change may also result in
increased production rates in other process areas and, therefore, an increase in associated actual
emissions. The proposed modification will not change the status of the facility with respect to the
applicability of Title V or National Emission Standards for Hazardous Air Pollutants (NESHAP) programs.
The proposed emission increases will not exceed the Prevention of Significant Deterioration (PSD)
Significant Emission Rates (SER) and therefore will not trigger PSD review.
Chemours requests that the NC Division of Air Quality(DAQ) process this 15A NCAC 02Q .0300 permit
application using the two step permitting process outlined in 15A NCAC 02Q .0501(b)and 15A NCAC
02Q .0504. To satisfy the requirements of 15A NCAC 02Q .0501(b)(2), Chemours will submit the Part 2
permit application within twelve(12) months after commencing operation of the new FilmtruderT'", to
request incorporation of the new sources into the Title V Permit and associated permit shield. Chemours
requests the opportunity to review the draft permit before it is issued for public comment.
This application is organized as follows:
■ Section 2.0 includes a description of facility processes and permit actions requested in this
application.
Section 3.0 includes emission estimates as well as a description of emission estimation
methodologies and PSD applicability evaluation.
r Section 4.0 includes an air regulatory applicability analysis.
■ Appendix A includes NC DAQ Permit Application Forms and Zoning Consistency.
e Appendix B contains a process flow diagram of the proposed equipment.
■ Appendix C presents the emission calculations for the proposed modification and affected sources.
■ Appendix D discusses MON applicability and the MON Pre-Compliance report.

AIR PERMIT APPLICATION FACILITY AND PROJECT 3ESCRIPTION
Installation of Wiped Film Evaporator in IXM Resins Process
2. FACILITY AND PROJECT DESCRIPTION
2.1 Current Facility Description
The Chemours Company—Fayetteville Works facility is located near Duart Township in Bladen County,
North Carolina. The facility is located approximately 15 miles southeast of the City of Fayetteville on NC
Highway 87, south of the Bladen-Cumberland county line. Currently, the facility manufactures plastic
sheeting,fluorochemicals, and intermediates for plastics manufacturing.
Specific materials produced at the Fayetteville facility are:
Ira ChemoursTM Nafion(D Membrane(plastic film) used in the chloroalkali industry and in electrochemical
fuel cells.
m ChemoursTM Nafion®Polymer Dispersions used in the fabrication of thin films and coating
formulations for fuel cells membranes, catalyst coatings, sensors, and a variety of electrochemical
applications.
* HFPO monomer and Vinyl Ether monomers used to manufacture various fluorochemical products
such as ChemoursTM Teflon@.
Fluorocarbon intermediates for Nafion@ membranes and other fluorocarbon products, and
A Fluoropolymer Processing Aids (PPA) used in the manufacturing of fluoropolymers and fluorinated
telomers.
In addition to the manufacturing operations, Chemours operates two natural gas-fired boilers and a
wastewater treatment plant(WWTP)for the treatment of process and sanitary wastewaters from
Chemours, Kuraray, and DuPont(both Kuraray and DuPont are also located on the site). However, no
wastewater is discharged currently from the Chemours facility to the WWTP, except reject water from
making filtered, deionized/degassed water at the power plant.At this time, all process wastewater
generated from the Chemours Company—Fayetteville Works manufacturing facility is collected and
shipped off-site for disposal.
2.2 Requested Permitting Actions
Chemours is submitting this permit application to install a second Wiped Film Evaporator(FilmtruderTM)
into the existing IXM Reins Process (ID No. NS-G-1). The proposed FilmtruderTM is similar to the existing
film evaporator except it is larger and will be installed in parallel with existing equipment. It is a two square
meter jacketed LCI FilmtruderTM used in a continuous process to isolate vinyl ether polymers. This project
will also install equipment to process the vapor and polymer exiting the isolation unit, and a new electric
heating system. The project will include installation of the new FilmtruderTM with vapor condenser, a
polymer processing system, and a hot oil system. The primary business objectives for this project are to
increase polymer capacity of the Resins area by—30%. The new equipment will be installed as an
extension to the polymer production area of building 456. The existing FilmtruderTM with vapor and
polymer processing associated equipment will remain in place. Heating to the new equipment will be
supplied by an electric heated hot oil unit.Vapor that exits the new Filmtruderrm unit will be condensed in
a new brine supplied condenser. The Condenser bottoms will be connected to the existing recirculation
tank.A new eductorjet and pump to pull vacuum on the existing and new FilmtrudersTM will replace the
existing eductor and pump. Table 2-1 provides a detailed listing of the equipment to be installed.
Chemours will continue to manufacture existing products in compliance with the existing permit.The
proposed modification will not result in changes to the current permitting status of the facility as a major
Title V source of criteria pollutants and a major source of HAPs.

Equipment to be Description
Installed
I
FilmtruderTm The polymer isolation vessel will be a wiped film evaporator that vaporizes solvent and
unreacted monomer from polymer slurry. Slurry feed will enter the Filmtruderrm through
a tangential feed inlet above the top thermal section.A distribution ring on the agitator
rotor will sling the slurry around the circumference of the unit.As gravity draws the
slurry downward, the agitator blades will spread the slurry over the Filmtruder'STM
internal surface area,and progressively push it downward where volatile components
will be rapidly evaporated and pulled from the top.Vapor will travel upward, and be
drawn out of the FilmtruderTM and through the vapor filter and brine condenser by a
vapor eductor. The melt pump will push solid polymer through the transition piece and
into the Polymer Processing System.
Polymer Processing Solid polymer will exit the melt pump and transition piece and then be pushed through
System the Pelletizer Die and out the die holes. Polymer exiting the die holes will enter the
water box area where it is cut into pellet form by the pelletizer rotating knives and
cooled by demineralized water.The die will be heated by eight heating elements.Water
from the Quench Tank System will cool the molten cubes and transfer them to a forced
air dryer.
Heated Oil A new electric heated oil recirculation system will be used to provide heating to the
Recirculation System equipment.The overall capacity of the heating system will be 80 kW.The unit will be
self-contained system with dual heating elements, circulation pump and fluid reservoir.
The entire system including the expansion tank is to hold approximately 35 gallons of
heat transfer oil during normal operation.
Vapor Condenser Vapors from the FilmtruderTM will vent through a Vapor Filter to capture any entrained
polymer from the vapor line before it enters the Brine Condenser. The Brine Condenser
condenses any vinyl ethers(VE)and solvent vapors.VE and solvent vapors will enter
the top, condense, and drain to the existing Recirculation Tank. Non-condensable TFE,
N2, or 02 vapors will be vented from the system to the Filmtruder Jet Eductor and then
to the existing Recirculation Tank which will vent to the existing Thermal
Oxidizer/Scrubber system.

AIR PERMIT APPLICATION PSD APPLICABILITY AND PROJECT EMISSION ESTIMATES
Installation of Wiped Film Evaporator in IXM Resins Process
3. PSD APPLICABILITY AND PROJECT EMISSION ESTIMATES
The manufacturing process at the Chemours—Fayetteville Works facility emits various criteria pollutants
and HAPs to the atmosphere. This section describes the methodology used to quantify project emissions
and assess PSD permitting applicability for the proposed modifications. Detailed emission calculations
are presented in Appendix C.
Chemours is located in Bladen County which has been classified as"attainment/unclassifiable"for all
criteria pollutants.As such, any new construction or modifications that result in emission increases are
potentially subject to the PSD permitting regulations. PSD applicability depends on the existing status of
the facility (i.e. major or minor source) and the net emissions increase associated with the project.
Chemours is considered an existing major source under the PSD permitting program for purposes of New
Source Review(NSR)as it belongs to one of the 28 PSD listed source categories (as listed in 40 CFR
51.166(b)(1)(iii)(t)) and has the potential to emit(PTE)greater than 100 tons per year(tpy) of NSR
pollutants. Therefore, the emission increases from the modifications proposed in this application must be
evaluated against PSD major modification SERs for each NSR pollutant to determine PSD permitting
applicability.
A description of the methodologies used to determine the pollutant emission rates for the proposed
modification are detailed throughout this section. Baseline actual emissions (BAE)for this comparison are
based on the period of January 2018 to December 2019. Based on the emissions detailed in this section,
the proposed modification will not be subject to PSD review for any applicable pollutant as the emissions
increases associated with the proposed modification are less than the PSD SERs.
3.1 New Source Review Significant Emission Rates
There are three criteria for determining whether the proposed FilmtruderTM project will be subject to PSD.
The first is to determine if the project is significantly large enough to be classified as a major modification.
The second criterion is that the source be located in an attainment or unclassified area. As previously
detailed, Chemours is located in an attainment/unclassified area. The third criterion is whether the net
emission changes result in an increase in excess of the NSR SER thresholds. For example, if the project
emission increases are significant, then an evaluation of net emissions (sum of contemporaneous and
creditable emission increases and decreases) is conducted.
To address the first criterion, a project is considered a major modification if it emits a regulated NSR
pollutant in amounts equal to or greater than specified significant increases. Regulated NSR pollutants
include:
Any pollutant for which a NAAQS has been developed and any constituents or precursors identified
by the USEPA;
Any pollutant regulated under a New Source Performance Standard (NSPS);
e Any material identified as contributing to the depletion of stratospheric ozone;
ri Any other material regulated under the CAA except for Hazardous Air Pollutants (HAPs); and
n Greenhouse gases (GHG).
The significant thresholds as defined in 40 CFR 51.166(b)(23)(i)for each regulated NSR pollutant are
presented in Table 3-1. The significance thresholds are established by the PSD regulations, as the level
of increase that would trigger PSD review at an existing major stationary source. However, it is not the
emissions increase from the new or modified equipment or emission sources alone that determines PSD
applicability. Other emission sources at the facility must also be evaluated to determine whether emission
increases could occur because of the addition of the new or modified emission sources. If the project is
www.erm.corn Version:2.0 Project No.:0527584 Client:Chemours September 2020 Page 4

AIR PERMIT APPLICATION PSD APPLICABILITY AND PROJECT EMISSION ESTIMATES
Installation of Wiped Film Evaporator in IXM Resins Process
determined to result in a significant emissions increase, the increase may be combined with other
emissions increases and decreases made at the facility contemporaneously with the specific project.
Then if the net result is greater than the significant amount, the specific project is determined to result in a
significant net emissions increase and is subject to PSD. If the first step does not result in a significant
emissions increase, then it is not necessary to determine the net emissions increase.
The proposed FilmtruderTM and associated equipment will be installed as part of the existing IXM Resins
Process (ID No. NS-G-1) and is expected to result in a 30% increase in production in the Resins Process.
It has also been determined that other process areas at the Chemours—Fayetteville Works facility may
be affected by the increase in production in the Resins Process.As such, the emission increases from the
Resins Process as well as other affected areas were evaluated to determine if this project would increase
emissions in excess of the SERs and therefore trigger PSD review.As shown in Table 3-1, for the
FilmtruderTM project, the emissions review included criteria pollutants, carbon dioxide equivalent(CO2e),
and sulfuric acid mist(H2SO4).

3.2 Project Emissions
Production rates and actual emissions will increase because of the installation of the new FilmtruderTM
which is vented through the condenser to the FilmtruderTM eductor jet and then to the existing
recirculation tank. The recirculation tank currently vents to the Thermal Oxidizer/Scrubber System (CD
No. NCD-Q1 and NCD-Q2)and will continue to vent there following installation of the new equipment.
For this project, the potential emissions will increase by 30% over the existing potential emissions from
the Resins Process (ID No. NS-G-1). The existing maximum production rate was multiplied by 30% in
order to determine the post-project production capacity. Likewise, the post-project potential emissions

AIR PERMIT APPLICATION PSD APPLICABILITY AND PROJECT EMISSION ESTIMATES
Installation of Wiped Film Evaporator in IXM Resins Process
were calculated by scaling up the CY20181 emissions by the ratio of the CY2018 production to the post-
project maximum production rate and applying a thermal oxidizer control efficiency of 99.99%for process
vent VOCs. Emissions Of S02 and CO2 generated by the thermal oxidation of compounds containing
carbon and sulfur were also calculated.A scrubber control efficiency of 99.95%was utilized for
calculating potential S02 emissions.
The detailed emission calculations are included in Appendix C.
BAE are defined as the average rate of emissions, in tons per year, from a source that actually occurred
over any consecutive 24-month period. The 24-month period must fall within a specific timeframe before
the project commences construction. BAE are used as the starting point for determining the magnitude of
changes associated with the proposed project in order to determine if the change will be subject to PSD.
For the FilmtruderTM project, past BAE were calculated by taking the average of the CY2018 and CY2019
actual emissions. The periods used for BAE were prior to the installation of the Thermal Oxidizer since
the Thermal Oxidizer was not installed to control VOC but rather under the Consent Order2 to control

installation of the Thermal Oxidizer/Scrubber system are considered "surplus"and creditable emissions'.

3.3 Debottlenecked Emissions
The increase in production in the Resins Process may also impact the emissions from many other areas
of the facility, which supply raw materials, further finish the Resins product, or supply additional steam
demand.
Chemours evaluated each area individually and determined the potential increase in production for the
affected process units as shown in Table 3-3. The increase in steam demand will result in an increase in
criteria pollutants other than VOC. Emissions of CO2e will occur with thermal conversion of the organic
fluorinated compounds in the thermal oxidizer resulting from the increased emissions associated
FilmtruderTM project.

Post-project emissions associated with each process area were determined by taking the maximum
emissions from either CY2018 or CY2019 and scaling up by the percentages shown in Table 3-3 and
applying a thermal oxidizer control efficiency of 99.99% for process vent VOCs. Emissions of S02 and
CO2 generated by the thermal oxidation of compounds containing carbon and sulfur were also calculated
for each affected process area.A scrubber control efficiency of 99.95%was utilized for calculating
potential S02 emissions. These future projected actual emissions were compared to the baseline actual
emissions for PSD evaluation. Detailed calculations for each affected process area are included in
Appendix C.
3.4 PSD SER for the FilmtruderTm Project
Table 3-4 shows a comparison of the project emissions, including increases associated with the Resins
Process and those other affected sources,to the SERs for each criteria pollutant, CO2e, H2SO4 and
ozone depleting substances(ODS).As depicted in the table, the proposed project will not result in an
increase in emissions in excess of the SER for any NSR pollutant. Therefore, the proposed project does
not trigger PSD review.

AIR PERMIT APPLICATION AIR REGULATORY APPLICABILITY ANALYSIS
Installation of Wiped Film Evaporator in IXM Resins Process
4. AIR REGULATORY APPLICABILITY ANALYSIS
The applicability determinations made for potentially applicable federal and state air quality regulations
are described in this section for the modifications proposed in the IXM Resins Process(ID No. NS-G-1).
Federal regulations are reviewed first, followed by North Carolina regulations. A summary detailing
applicability of each regulation is provided throughout this section.
4.1 Federal Requirements
4.1.1 Permitting Programs
4.1.1,1 Title V Operating Permit Program, 40 CFR 70
A Title V(Part 70) operating permit is required for facilities that meet the definition of a major source
according to 40 Code of Federal Regulations (CFR) Part 70.2.A facility with criteria pollutant emissions
greater than 100 tpy or 10 tpy of a single HAP or 25 tpy of a combination of HAPs is considered a major
source under the Title V permitting program. The Chemours facility is considered a major source with
respect to the Title V permitting program and operates under Permit 03735T48. Chemours will submit the
Part 2 permit application within twelve (12) months after commencing operation of the proposed
FilmtruderTM, to request incorporation of the new sources into the Title V Permit.
4.1.1.2 Prevention of Significant Deterioration (PSD), 40 CFR 52.21
The federal PSD program, codified in 40 CFR Part 52.21, requires any new major stationary source of air
pollutants to obtain a major source air construction permit before commencing construction. North
Carolina has incorporated the federal PSD program in 15A NCAC 2Q .0300. The PSD program applies to
a facility if potential emissions exceed applicable major source thresholds. The facility is considered a
chemical process plant, which is one of the 28 listed PSD source categories specified in §52.21(b)(1)(i)(a)
with a 100-tpy PSD major source threshold for regulated New Source Review(NSR) pollutants. Since the
existing facility is a major source with respect to the PSD program, modifications at the facility must
undergo major source review if the proposed project will increase emissions of one of the PSD regulated
pollutants in excess of the applicable pollutant SER threshold.
As detailed in Section 3,the emission increase of each NSR regulated pollutant associated with the
proposed project is less than the applicable SER. Therefore, the project will not trigger PSD review. Since
the administration of the Federal NSR program has been delegated to the NC DEQ,the application will
be processed in compliance with the state rules described in Section 4.2 below.
4.1.1.3 Nonattainment Area New Source Review (NNSR), 40 CFR 52121
NNSR is applicable to construction of a new major stationary source or a project that is a major
modification at an existing major stationary source in an area designated as nonattainment for the
National Ambient Air Quality Standards (NAAQS).The Chemours facility is located in Bladen County
which is classified as an attainment or unclassifiable county for all NSR pollutants. Thus, the facility is not
subject to NNSR.
4.1.2 New Source Performance Standards, 40 CFR Part 60
New Source Performance Standards (NSPS), codified in Title 40 CFR Part 60, establish pollutant
emission limits and monitoring, reporting, and recordkeeping requirements for various emission sources
based on source type and size. The NSPS apply to new, modified, or reconstructed sources as defined
www.erm.com Version:2.0 Project No.:0527584 Client:Chemours September202O Page 9

AIR PERMIT APPLICATION AIR REGULATORY APPLICABILITY ANALYSIS
Installation of Wiped Film Evaporator in IXM Resins Process
by particular NSPS. North Carolina has incorporated the federal NSPS in 15A NCAC 02D .0524. The
proposed FilmtruderTM and associated equipment will not be subject to any NSPS regulations.
4.1.3 National Emission Standards for Hazardous Air Pollutants, 40 CFR Part 61
and 40 CFR Part 63
National Emission Standards for Hazardous Air Pollutants (NESHAP)are generally applicable to sources
of HAP. The NESHAP regulations in 40 CFR 61 are pollutant-specific while the NESHAP regulations in
40 CFR 63 are established based on Maximum Achievable Control Technology (MACT) determinations
for particular source types.
None of the NESHAP regulations in 40 CFR 61 apply to the facility; however the facility is a major source,
of HAP as defined in 40 CFR 63.2. Several operations at the existing facility are subject to 40 CFR 63
MACT requirements including NS-G-1 which is subject to the requirements of 40 CFR 63, Subpart FFFF,
"National Emission Standards for Hazardous Air Pollutants: Miscellaneous Organic Chemical
Manufacturing" (also referred to as the Miscellaneous Organic NESHAP, or MON).
Appendix D includes a detailed MON applicability for the new sources proposed in this application.
Chemours will also identify any components subject to the requirements of 40 CFR§63.2480 for
Equipment Leaks and add those components to the Leak Detection and Repair(LDAR) program that is
already being conducted in the NS-G-1 area for existing equipment.
The MON also requires submittal of a Pre-compliance Report as specified in 40 CFR§63.2520(c)for new
sources with the application for approval of construction. This report is included in Appendix D. In
addition, as required by 40 CFR§63.2520(a), a notification of compliance status (NOCS) report is
required to be submitted no later than 150 days after startup of the new equipment and a Compliance
Report is required to be submitted semi-annually.
4.1.4 Compliance Assurance Monitoring (CAM), 40 CFR Part 64
Under 40 CFR Part 64, Compliance Assurance Monitoring (CAM), facilities are required to prepare and
submit monitoring plans for certain emission units with certain Title V permit applications. Specifically
CAM applies to any unit that meets all three of the following criteria:
■ be subject to an emission limitation or standard,
■ use a control device to achieve compliance, and
■ have pre-control emissions that exceed or are equivalent to the major source threshold.
The proposed modifications will occur as part of the Resins area (ID No. NS-G-1)that vents to the
Thermal Oxidizer/Scrubber system.A CAM plan for the Thermal Oxidizer/Scrubber system will be
submitted as part of the next Title V permit renewal application.
4.2 State of North Carolina Regulations
Potentially applicable standards under 15A North Carolina Administrative Code(NCAC) Chapter 02,
Environmental Management are discussed in the following section.
4.2.1 15A NCAC 02D .1111- Maximum Achievable Control Technology
This rule implements the federal MACT standards. Compliance with the federal MACT standards is
discussed in Section 4.1.3
www.ean.com Version:2.0 Project No.:0527584 Client:Chemours September 2020 Page 10

AIR PERMIT APPLICATION AIR REGULATORY APPLICABILITY ANALYSIS
Installation of wiped Film Evaporator in IXM Resins Process
4.2.2 15A NCAC 02D .0521 - Control of Visible Emissions
This rule applies to"industrial processes where an emission can reasonably be expected to occur". For
sources installed after July 1, 1971, visible emissions are limited to no more than 20 percent opacity when
averaged over a six-minute period. Visible emissions are not expected from the FilmtruderTM process and
Chemours will continue to comply with the rule as applicable throughout the facility.
4.2.3 15A NCAC 02D .0530— Prevention of Significant Deterioration
As discussed in section 4.1.1.2,the current facility is a major source with respect to the PSD regulations.
As such, the increase in emissions associated with any modification at the facility must be assessed
against the appropriate SER. As detailed in Section 3, the emission increase of each PSD regulated
pollutant associated with the proposed project is less than the applicable SER. Therefore, the project will
not trigger PSD review. Chemours requests to maintain the current PSD avoidance limit for NS-G-112 as
specified in permit condition Section 2.1(B)(6). Chemours also requests to maintain the current PSD
avoidance limits for other applicable affected sources. The requested permit modification will not be a
major modification with respect to PSD.
4.2.4 15A NCAC 02Q .0300— Construction and Operation Permits
The owner or operator of a new, modified, or existing facility or source is required by 15A NCAC 02Q
.0300 to apply for and obtain a construction permit. This application is a request to modify the existing
permit by adding the FilmtruderTM and associated equipment as part of the existing IXM Process (NS-G1).
As stated previously, Chemours is requesting that NC DAQ process this application using the two step
permitting process outlined in 15A NCAC 02Q .0501(b) and 15A NCAC 02Q .0504. This application
initiates the request for the permit modification.
4.2.5 15A NCAC 02Q.0500— Title V Procedures
As noted in the Federal Regulations section, the Title V permitting program does apply to the Chemours
Fayetteville Works that currently operates under Title V permit number 03735T48.
4.2.6 15A NCAC 02Q. 0700- Toxic Air Pollutant Procedures and 15A NCAC
02D.1100- Control of Toxic Air Pollutants
The Toxic Air Pollutant Procedures require a permit for any facility with emissions of an Air Toxic Pollutant
listed 15A NCAC 02D .1104 in excess of the applicable Toxic Pollutant Emission Rates (TPER) Requiring
a Permit presented in 15A NCAC 02Q. 0711. The current permit for the Chemours facility contains facility-
wide emission limits for each of the applicable pollutants emitted at the facility[Permit Condition 2.2(B)(1)
and 2.2(B)(2)]. The installation of the proposed FilmtruderTM and associated equipment will not result in
an increase in emissions of any regulated air toxic compound in excess of the permitted rates.

APPENDIX D MON APPLICABILITY AND PRE-COMPLIANCE REPORT
The business of susfainabilify ERM

40 CFR 63 Subpart FFFF-NESHAP: Miscellaneous Organic Chemical Manufacturing
The NS-G-1 process uses one HAP, methanol in trace amounts(parts per million)to control polymer
properties and then it is used in larger quantities (1%-2% by weight)to terminate the polymerization chain
and stop the reaction. Methanol is entrained in the gas phase of the first separation phase and is
removed by the subsequent scrubbing operation and directed with the effluent to the facility wastewater
system. Some methanol is also carried over in the liquid phase with the recycled solution and is then
removed using molecular sieves in a later purification process. The use of a HAP and the nature of the
operation make this process subject to the MON.
Table D-1 lists the proposed process equipment and the related compliance status. None of the new
equipment will be subject to emission limits or control requirements and the status of existing equipment
will remain as is. The installation and operation of the proposed new equipment will not require
"reconstruction" as defined in 40 CFR 63.3 of the existing process equipment. The compliance status for
the existing equipment was addressed in a notification submitted to the North Carolina Division of Air
Quality in 20084.
The fugitive components (valves, pumps, connectors, agitators, pressure relief devices, and open ended
lines)associated with the expansion project are subject to the work practice standards for equipment leaks
specified in Table 6 to Subpart FFFF of Part 63. Chemours will identify each new component containing
methanol in excess of 5% (excluding equipment in vacuum service) as the project design is finalized. The
identified components will be incorporated into the existing LDAR program. Monitoring of pumps and valves
are conducted at the frequencies specified in§63.1025(b)(3)and §63.1026(b)(1).

The THE of the existing Recirculation Tank was re-evaluated to verify that under the new process
conditions the vent would remain a Group 2 Continuous Process Vent with a THE above 1.9. Group 2
Continuous process vents are subject to the control requirements of Table 1 to Subpart FFFF of Part 63.
That table requires no additional controls for a Group 2 continuous process vent at an existing source
with a THE greater than 5. Therefore, based on the THE calculated below, no further controls are
required for this process vent.
THE Calculation
THE for the Recirculation Tank(an existing Group 2 continuous process vent) is calculated based
on 40 CFR 63.115(d)(3)(1)as:
THE = (1IEHAP)(a+b(QS) + (c(Ht)+d(Eta,))
Where,
THE = total resource effectiveness index value,
EHAP= kilograms per hour(kg/hr)of total organic HAPs,
Qs=vent stream flow rate(standard cubic meters per minute) at 20°C,
Ht= net heating value of sample([MJ/Nm3]),
EToc= kg/hr of TOC,
a,b,c,d = Coefficients are presented in table D-2 for existing sources.

MON Pre-Compliance Report
40 CFR§63.2520(a) requires the submittal of a Pre-compliance Report as specified in 40 CFR
§63.2520(c). The Pre-compliance Report for new sources is required to be submitted with the application
for approval of construction. As shown above, none of the process equipment will be required to meet any
of the emission limits or install controls. Therefore, only fugitive leaks will need to be addressed for
compliance with 40 CFR 63 Subpart FFFF. The regulated equipment will be identified and incorporated
into the LDAR program already in existence for this area.
(c)(1) Requests for approval to set operating limits for parameters other than those specified in
§§63.2455 through 63.2485 and referenced therein.Alternatively, you may make these requests
according to§63.8(f).
Chemours will not be required to set operating limits for any of the new equipment to be installed.
(c)(2) Descriptions of daily or per batch demonstrations to verify that control devices subject to
§63.2460(c)(5) are operating as designed.
Based on the preliminary review of the equipment that will be subject to MON and the previous
analysis of similar existing equipment in NS-G-1, a control device will not be required.
(c)(3)A description of the test conditions, data, calculations, and other information used to establish
operating limits according to§63.2460(c)(3).
Based on preliminary review of equipment that will be subject to MON and previous analysis of
similar equipment in NS-G-1, there will be no operating limits required.
(c)(4) Data and rationale used to support an engineering assessment to calculate uncontrolled emissions
in accordance with§63.1257(d)(2)(ii). This requirement does not apply to calculations of hydrogen halide
and halogen HAP emissions as specified in §63.2465(b), to determinations that the total HAP
concentration is less than 50 ppmv, or if you use previous test data to establish the uncontrolled
emissions.
Applicability and emission rate calculations, where applicable are included in tables in this
Appendix.
(c)(5)The pollution prevention demonstration plan required in§63.2495(c)(1), if you are complying with
the pollution prevention alternative.
Chemours is not planning to use the pollution prevention alternative to comply with the MON
requirements.
(c)(6) Documentation of the practices that you will implement to minimize HAP emissions from streams
that contain energetics and organic peroxides, and rationale for why meeting the emission limit specified
in Tables 1 through 7 to this subpart would create an undue safety hazard.
Based on preliminary calculations and previous assessment, the requirements of Tables 1
through 5 and 7 will not apply to the equipment. Table 6 of 40 CFR 63 Subpart FFFF requires a
new source to comply with 40 CFR 63 Subpart UU. Components in the HAP service that are
required to meet the requirement of Table 6 will be identified and incorporated into the existing
MON program at Chemours.

(c)(7) For fabric filters that are monitored with bag leak detectors, an operation and maintenance plan that
describes proper operation and maintenance procedures, and a corrective action plan that describes
corrective actions to be taken, and the timing of those actions, when the PM concentration exceeds the
set point and activates the alarm.
Chemours is not required to install fabric filters under 40 CFR 63, Subpart FFFF.
