DESCRIBE IN DETAILTHE EMISSION SOURCE PROCESS (ATTACH FLOW DIAGRAM):
For general good housekeeping purposes, the DuPont Company - Fayetteville Works' PVF-1 Process uses
a vacuum system to remove the PVF resin powder from the building's floor and equipment. The emission
of particulate matter from the vacuum system is controlled by a two -stage fabric filter from TDC Filter: the
QX Filter (CD -Vac -Al) capture / control efficiency is 48% for particles less than 1.0 pm and 88% for
particles greater than 1.0 pm; the SB-ME Filter Media (CD-Vac-A2) capture / control efficiency is 38% for
particles less than 1.0 pm, 72% for particles between 1.0 pm and 3.0 pm, and 98% for particles greater than
3.0 pm. It is assumed the CD-Vac-A2 capture / control efficiency is 38% for particles less than 1.0 pm, and
72% for particles greater tha 1.0 pm. For potential emissions determination, it is assumed the before -
control solids loading is three times (3X) greater than typical.

DESCRIBE IN DETAILTHE PROCESS (ATTACH FLOW DIAGRAM):
For general good housekeeping purposes, the DuPont Company - Fayetteville Works' PVF-1 Process uses
a vacuum system to remove the PVF resin powder from the building's floor and equipment. The powder
is collected in 340-lb bags that are disposed of in an off -site Subtitle D landfill.
The emission of particulate matter from the vacuum system is controlled by a two -stage fabric filter from
TDC Filter: the QX Filter (CD -Vac -Al) capture / control efficiency is 48% for particles less than 1.0 pm and
88% for particles greater than 1.0 pm; the SB-ME Filter Media (CD-Vac-A2) capture / control efficiency is
38% for particles less than 1.0 pm, 72% for particles between 1.0 pm and 3.0 pm, and 98% for particles
greater than 3.0 pm.

COMMENTS:
The basis for the Maximum Design value of 0.014 batches/hour is from the 40,800 Ib/yr of solid waste
generated that was the basis of the Potential to Emit for this source. This quantity is three times the
typical solid waste generated from this housekeeping operation. It is assumed that one "batch" is equal
to one 340-lb bag of collected solid waste. The 40,800 lb. of collected powder would equal 120 of the 340-
lb. bags used with this vacuum. The 120 bags/year equals 0.014 bags/hour or 0.014 batches/hour.

COMMENTS:
Actual and potential emissions of total particulate matter has been estimated and reported in this
application. A size distribution of the particulate matter has not been performed, therefore the fractions of
the particles that are <2.5 micron and <10 micron are not know, and are reported as merely being less than
the total quantity of particulate matter.
The Potential to Emit of both volatile organic compound (VOC) and Particulate Matter < 10 microns (PM-10)
is less than the 100 ton/year PSD threshold for both pollutants.
The facility can emit small quantities of formaldehyde, which is created as a decomposition product in the
high temperatures of the PVF Dryer. A laboratory simulation of the dryer was made and analysis of that
dryer's exhaust air showed the potential uncontrolled emission of formaldehyde to be 0.01 Ib/hr for each
process and a facility -wide total of 0.02 lb/hr. This potential emission rate is less than the 0.16 Ib/hr toxic
permit emission rate ("TPER") of formaldehyde that would require a permit per 15A NCAC 02Q .0711(b).

FORM D3
MODELING REQUEST FORM
RFVn,;F-n• n?/2o/03 NCDENR/Division of Air Quality - Application for Air Permit to Construct/Operate D3
If the applicant desires, the NCDAQ/AQAB will perform the initial modeling compliance demonstration using EPA approved
screening and, if applicable and where possible, refined models. If the model results indicate the facility will be unable to
demonstrate compliance with applicable Acceptable Ambient Level(s) the applicant will be notified and will be required to
perform the compliance demonstration using established modeling protocol and modeling analysis requirements as defined in the
North Carolina Administrative Code 15A NCAC 2D .1100 and 2Q .0700 and in the Guidelines for Evaluating the Impacts of Toxic
Pollutants in North Carolina.
To perform the dispersion modeling compliance demonstration, the AQAB will require the following data:
1. INTRODUCTION
Provide a brief description of the modification and/or addition necessitating the toxic modeling request:
The facility can emit small quantities of formaldehyde, which is created as a
decomposition product in the high temperatures of the PVF Dryer. A laboratory
simulation of the dryer was made and analysis of dryer's exhaust air showed the potential
uncontrolled emission of formaldehyde to be 0.01 Ib/hr for each process and a facility -
wide total of 0.02 lb/hr. This potential emission rate is less than the 0.16 lb/hr toxic permit
emission rate ("TPER") of formaldehyde that would require a permit per 15A NCAC 02Q
.0711(b). Therefore this application for a minor air permit requires no modeling.
