DUPONT FLUOROPRODUCTS POLYMER MANUFACTURING DEVELOPMENT
FACILITY (PMDF) AIR PERMIT APPLICATION
Overview
DuPont Fayetteville Works plans to construct a new Fluoroproducts Polymer Manufacturing
Development Facility (PMDF). The Polymer Manufacturing Development Facility will have an
emission source ID of "FS-A". The "FS-A" nomenclature is consistent with the nomenclature
used in the DuPont Title V air permit application.
Polymer Manufacturing Development Facility Operation
IThe Polymer Manufacturing Development Facility will involve:
1. Laboratory, testing, and R&D operations housed in a new PMDF building, and
I2. Pilot -scale production operations housed in the same new PMDF building.
It is worth pointing out that the Polymer Manufacturing Development Facility may include
I several laboratory hood operations would be used strictly for non -production purposes and will
be categorically exempt per NCAC 2Q .0 1 02(b)(1)(C) - Laboratory Equipment.
Modeling Demonstration
A North Carolina Air Toxics modeling demonstration was performed as part of the Nafion®
Semiworks 3 air permit application. As part of that permit, virtually all North Carolina toxic air
pollutants (TAPS) were modeled and facility -wide permit limits were established such that
compliance is demonstrated regardless of which stack the emissions are coming from. This was
done using a "worst -case unit impact" approach and this approach is described in detail in the
modeling section of the Semiworks 3 air permit application and as part of Form D6 of this
application.
The unit impact from the Polymer Manufacturing Development Facility is 2.5 µg/m3 as
determined by using the EPA SCREEN3 model (see Exhibit A) versus the "worst -case unit
impact" of 65 µg/m3. Therefore, the emission quantities determined in the above mentioned
modeling which meet the Ambient Air Limit (AAL) for each TAP, and the resulting permitted
TAP limits in the current air permit, are still germane.
' Regulatory Analysis
The PMDF unit will install two air emission control devices: a venturi scrubber (FCD-Al) and a
I fabric filter (FCD-A2). It must be pointed out that the before -control potential emission rate of
0.1 lb/hr HF for FCD-A1 is an insignificant increase when compared to the current actual HF
average emission rate of 0.53 lb/hr versus this site's TAP limit of 10 lb/hr. It must also be
' pointed out that the before -control potential emission rates of 140 lb/yr TSP for FCD-A2 is less
than five tons per year, and therefore would qualify as an insignificant activity without the
control device. Therefore, there are no applicable State or Federal regulations that require the
IPMDF unit to install either of these control devices. Consequently, both the Forms C2 and C7
list the "corresponding efficiency" as "50%". Therefore, DuPont requests that no Inspection and
I Monitoring (I&M) conditions be established for these control devices, and that the 2Q.0112
requirement for a Professional Engineer's seal be waived.

DEQ-CFW 00088324

The PMDF operation will be subject to the North Carolina Air Toxics rule which applies to the
facility as a whole. In addition, DuPont is requesting that when a permit is issued for the
Polymer Manufacturing Development Facility, that it include a condition that limits total VOC
emissions from The Polymer Manufacturing Development Facility activities to 39.9 tons per
year.
It should be pointed that the emissions determination and recordkeeping requirements are very
difficult and time consuming due to the nature of the Polymer Manufacturing Development
Facility which is mainly a Research and Development facility which will include laboratory and
testing equipment.
Even though DuPont has requested a <40 TPY VOC emissions limitation for the Polymer
Manufacturing Development Facility, we believe that the PMDF unit should not be subject to the
rigorous monitoring and recordkeeping requirements usually required for a PSD avoidance
permit. DuPont believes that a requirement to determine the VOC emissions on a monthly basis
with a requirement to report quarterly to NCDENR, will more than adequately prevent the
possibility that the PMDF operation could ever exceed 40 TPY VOC which would then become
a PSD review issue.
Additionally, DuPont plans on tracking emissions from the Polymer Manufacturing Development
Facility for annual fee purposes as well as for assuring compliance with the facility -wide air
toxics limits. However, it should be pointed out, that for essentially all of the toxic air pollutants,
the allowable emission limits, as determined through the worst -case unit impact approach (see
modeling section), are many times greater than actual emissions, and therefore, rigorous
monitoring and recordkeeping requirements for TAPs are not necessary.

COMMENTS: Most of the activities of the PMDF unit would be categorically exempt from permitting as it is a
research facility. However, DuPont's intention is to sell the products produced at this facility, hence a permit is
needed to construct and operate the PMDF unit. Specific materials to be used in the PMDF unit cannot be defined
at this time due to the unknown nature of these research activities.

COMMENTS: Limits for all toxic air pollutants presented here (except for HF and HCQ are facility -wide emission
limits based on emissions from a single "WORST -CASE PSUEDO" emission point. Air toxics modeling was
performed in this manner because flexibility is needed for the semiworks operations to possibly use all of
these TAPs. Allowable emissions have been "backed -out' from the predicted ambient impact associated with
the worst -case emission point (see D6 Form). In general, modeling should not be required for future new or
modified emission units as long as facility -wide emissions remain below these facility -wide limits. See the

COMMENTS: An air dispersion modeling analysis has been performed for all North Carolina toxic air pollutants
(TAPs) except for asbestos and some metal compounds (see Form D2-1 for a complete listing of the TAPs).
Modeling has been performed for all of these TAPs in order to have the flexibility needed to operate the 'Naf!on"
Semiworks Facilities and the PMDF unit. For all the TAPs except hydrogen fluoride and hydrogen chloride,
facility -wide emission limits for each TAP were backed -out of the modeling using a single worst -case emission
point. For hydrogen fluoride and hydrogen chloride, facility -wide limits were backed out using two worst -case
emission points. See the modeling analysis for additional discussion.
Any TAP emissions from the PMDF unit will be limited by the existing site -wide TAP emission limits set in this
site's current air permit.

COMMENTS: The Polymer Manufacturing Development Facility is a research and development facility. A wide
variety of different materials can be used and it is not possible to define specific quantities of usage for individual
compounds. See Form D2-1 for the facility -wide TAP emission limits. These limits include emissions from the
PMDF unit.
The potential VOC emission rate is a voluntary limit to avoid PSD regulations. The PMDF unit will operate such

Emission Unit ID: FS-A
Emission Source Description: Polymer Manufacturing Development Facility (PMDF)
A. VOC Emission Limitation Analysis:
The Polymer Manufacturing Development Facility is primarily an R&D operations, and the actual materials that will be used in the operations
cannot be specifically defined. However, pollutants that might possibly be emitted from the PMDF that could be subject to regulation include
VOC (if emissions were high enough the PSD regulation could be triggered) and North Carolina toxic air pollutants (TAPs). DuPont has chosen
to take a self-imposed limit of 39.9 tons per year VOC from the PMDF unit, and this limit then defines potential VOC emissions. The first
anticipated process and product is expect to have routine "actual' emissions of 20.5 TPY VOC.
B. TAP Emission Limitation Analysis:
Air toxics modeling has been performed to determine allowable emissions for all TAPs that may be emitted from the PMDF unit, and this then
defines potential TAP emissions. See the SCREEN3 modeling output (Exhibit A) for additional information. Below, the calculations that were
used to "back -out" allowable emissions are summarized.
Allowable TAP emissions are calculated using a pseudo worst -case unit impact (µg/ni). This pseudo unit impact represents the highest ambient
concentration that any emission point at the DuPont site would ever cause for an emission rate of 1 lb/hr. Modeling has been performed to show
that all emission points at the site actually have a unit impact lower than the pseudo -worst case unit impact. Because there is a direct linear
correlation between ambient impact from a single emission point and emissions, the allowable emissions can then be backed out from the pseudo
unit impact. In this way, allowable emissions for all TAPs can be calculated based on the allowable ambient concentration and the pseudo worst -
case unit impact. Because each of the actual emission units at the Fayetteville site have a unit impact lower than the pseudo worst case impact,
compliance with the air toxics rule will be assured regardless of which emission units the TAPs are actually emitted from. Example calculations
for determining allowable limits are presented below.
The pseudo worst case unit impact used for the DuPont Fayetteville site is 65 µg/m3. All emission points at the facility have a lower unit impact.
The unit impact from the PMDF unit is 2.5 µg/m3 (see Exhibit A for SCREEN3 output),

Pollutant with 15-minute limit — Formaldehyde
Formaldehyde AAL = 0.15 mg/m3
Worst case unit impact associated with 1 lb/hr emissions equals 65 µg/m3
Backed out allowable emissions = 1 lb x 1 hr x 0.15 mx 1000 ue x m3 x 0.95 (allowed fraction) _
hr 4 (15 min) m3 mg 65 µg
0.55 lb/l5-min allowable emissions
Thus, if 0.55 lb/ 15-min were emitted from the pseudo worst case stack the predicted impact would be 95% of the AAL.
Pollutant with 24-hr limit -- Vinylidene Chloride
Vinylidene Chloride AAL = 0.12 mg/m3
Worst case unit impact associated with 1 lb/hr emissions equals 65 ug/m3 which converts to 26 ug/m3 on a daily basis (See Table 4.1 in the
North Carolina Modeling Guidelines document).
Backed out allowable emissions = 1 lb x 24 hr x 0.12 mg x 1000 uu x m3 x 0.95 (allowed fraction) _
hr day m3 mg 26 µg
105.2 lb/day allowable emissions
Thus, if 105.21b/day were emitted from the pseudo worst case stack the predicted impact would be 95% of the AAL.
SO,
6 A similar approach is used to determine both the hourly and annual limits for all of the North Carolina TAPS except HF and HCl, and the
i:* calculations for this are attached on the following pages. The approach used for HF and HCI is discussed below.

HF and HCl allowable emissions:
HF and HCl allowable emissions were backed out using two worst -case pseudo unit impact values. The allowable emissions are divided up
between the two unit impact values. A specified amount of HF and HCl are emitted from the second worst -case pseudo unit impact value. This
will result in a predicted concentration that is a fraction of the AAL. The remaining ambient impact is backed out from the overall worst case unit
impact. This approach results in essence two limits for HF and HCL. One limit from all stacks which have a unit impact less than the 2nd Worst
Case Unit Impact Value and another limit for all other stacks.
Calculations for doing this are presented below.
2nd Worst -Case Unit Impact Value:
Overall Worst -Case Unit Impact Value:
Hydrogen fluoride 24 hour AAL:
Hydrogen fluoride 15-min hour AAL:
Hydrogen chloride 15-min hour AAL:
10 11g/m3 (Unit Impact 2)
65 µg/m3 (Unit Impact 1)
0.03 mg/m3
0.25 mg/m3
0.7 mg/m3
Maximum Allowable HF and HCl Associated with Worst Case Unit Impact 2:
Worst case unit impact 2 associated with 1 lb/hr emissions equals 10 µg/m3 on an hourly basis and 4 µg/m3 on a daily basis
Backed out allowable HF = 1 lb x 1 hr x 0.25 mg x 1000 ug x m3 = 6.25 lb/15-min
emissions (lb/15-minutes) hr 4 (15 min) in mg 10 µg
Backed out allowable HF = 1 lb x 24 hr x 0.03 me x 1000 ug x in = 180.0 lb/day
Emissions (lb/day) hr day in mg 4 µg
Backed out allowable HCl = 1 lb x 1 hr x 0.7 in x 1000 ug x in = 17.50 lb/15-min
emissions (lb/15-minutes) hr 4 (15 min) in mg 10 µg
HF and HCl emissions from the Worst -Case Unit Impact 2 emission points will consume 30% of the allowable emissions.
Thus emissions from the Unit Impact 2 emission points are as follows: HF
= 6.25
x 30%
= 1.875
lb/15-min
HF
= 180.0
x 30%

This leaves 65% of the AAL impact that can be consumed by emissions from Worst -Case Unit Impact 1 stacks (30% for the Unit Impact 2 stack
and 65% from Unit Impact 1 stack for a total of 95%). Thus allowable emissions are calculated as follows:
Maximum Allowable HF Associated with Worst -Case Unit Impact 1:
Worst case unit impact 1 associated with 1 lb/hr emissions equals 65 µg/m3 on an hourly basis and 26 µg/m3 on a daily basis
Backed out allowable HF = 1 lb x 1 hr x 0.25 me x 1000 ug x m3 x 0.65 (remaining fraction) _
emissions (lb/15-minutes) hr 4 (15 min) m3 mg 65 µg
= 0.625 lb/15-min allowable emissions
Backed out allowable HF = 1 lb x 24 hr x 0.03 mx 1000 u x m3 x 0.65 (remaining fraction) _
Emissions (lb/day) hr day m3 mg 26 µg
18.0 lb/day allowable emissions

emissions (lb/15-minutes) hr 4 (15 min) m3 mg 65 µg
= 1.75 lb/15-min allowable emissions
