2.0 BACKGROUND
DuPont Fayetteville
NC0003573
This is a permit renewal for a major industrial wastewater treatment facility with a current
facility design and permitted flow of 2.0 MGD with a discharge to the Cape Fear River just
downstream of Lock & Dam U.
In operation since 1970, this DuPont facility sits on approximately 2500 acres, 600 dedicated to
the current manufacturing facilities. Current facilities include the Butacite plant, the Nafion
plant, the Teflon plant, and the APFO plant.
2.1 Butacite®
Butacite® (polyvinyl butyral - PVB) is the plastic film that holds the two pieces of glass in an
automotive windshield together. The Butacite layer also provides much needed strength to
the windshield. While nearly 70% of DuPont's butacite goes to the automotive industry, more
and more is being used in the construction industry to satisfy new building codes requiring
such protective measures as hurricane resistant glass.
Butacite@ is manufactured in large rolls, shipped out in refrigerated trucks to glass
manufacturers. The refrigeration is a requirement as butacite sticks to itself at temperatures
above 600F. The Butacite plant manufactures finished butacite as well as polyvinyl butyral
resin for shipment to other DuPont facilities.
2.2 Nafion@
Nafion@ (Na - F - ion) is a fluorocarbon used in a number of industries. Also an extruded
resin and eventually a thin film, nafion, when subjected to an electric current in salt water,
makes NaOH and Cl gas. In this application it replaces the mercury process formerly used by
such companies as Holtrachem to manufacture chlorine. Nafion is also used in fuel cells to
generate electricity. The nafion plant manufactures five products including:
• Nafion® membrane - a plastic film used in the chloroalkah industry and
electrochemical fuel cells;
• Nafion® resins - ultimately extruded into film;
• Nafion® solution - generated during the production of resin;
• FLPR vinyl ether monomers - shipped to other DuPont locations to produce various
fluorochemical products such as Teflon.
• HFPO monomers - shipped to other DuPont locations to produce various
fluorochemical products such as Teflon.
2.3 Teflon@
DuPont's PMDF Teflon@ manufacturing area produces Teflon@ FEP resin. Teflon@ FEP resin
is used in the electronics industry as a coating for wire, as well as many other uses.
2.4 APF@
DuPont's APFO (ammonia perfluoro-oxidate) has just recently started production. It is a resin
used in the manufacture of Teflon. Concern has been raised about potential adverse health
effects resulting from exposure to APFO. This concern is addressed in the Other Issues
portion of this document

3.0 FACILITY INFORMATION
3.1 Outfall Summary
Outfall 001 is an internal outfall and is the effluent from the biological wastewater
treatment facility (see section 2.2.1 below). The treatment facility receives all sanitary
wastewater, process stormwater, co -neutralized regenerate, as well as process
wastewaters from Butacite, Dymetrol, Nafion, Teflon, and APFO. The applicable 414
subparts include D (thermoplastic resins) and I (end -of -pipe biological treatment). While
the permitted flow is 2.0 MGD, the flow used for guideline application was 0.946 MGD.
The long-term average production flow associated with this outfall was determined to be
0.863 MGD. However, the facility is expecting increased production associated with an
expansion and is projecting process wastewater flows of 1.085 MGD. The previous
permit limitations were developed using 0.946 MGD. As the facility is currently meeting
these limits, and 0.946 MGD seems to be a good median between the long-term average
flow and the projected flow, the limitations were maintained (thus determined using a
flow of 0.946 MGD).
Outfall 002 is the combined effluent to the Cape Fear River and includes all internal
outfalls in addition to non -contact cooling water, boiler blowdown, and stormwater.
Outfall 006 is an internal outfall consisting of Nafion low -biodegradable process
wastewaters. The applicable 414 subparts include D and J (end -of -pipe non -biological
treatment). The average process wastewater flow for this outfall is 0.036 MGD.
Outfall 007 is an internal outfall consisting of APFO low -biodegradable process
wastewaters. The applicable 414 subparts include H (special organic chemicals) and J.
The average process wastewater flow for this outfall is 0.048 MGD.
3.2 Wastewater Treatment
3.2.1 Liquid Train
Process wastewater and stormwater from the various manufacturing areas are collected in
the respective area sumps and ultimately conveyed via a gravity flow underground process
sewer pipe to the site's central wastewater treatment plant (WWTP). Sanitary sewage is
conveyed via a separate underground sewer system to the WWTP. The actual average flow
from the treatment facility is approximately 1.0 MGD.
Untreated wastewater is commingled in the influent sump where it is then pumped to an
850,000 gallon equalization basin. The equalization basin is mixed with two floating
submerged mixers. Three floating surface in the basin cool and aerate the incoming
wastewater.
A 175,000 gallon emergency retention tank is available for temporary storage of unsuitable
wastewater. This unsuitable wastewater, which typically exhibits a high organic content or a
chemical to which the activated sludge is not acclimated, is eventually treated in the WWTP
at a rate that allows for proper biological treatment.
Wastewater from the equalization basin is pumped to a 250,000 gallon pre -digester tank in
which initial biological treatment with the activated sludge begins. The tank is aerated with a
floating surface aerator as well as diffused air. The partially treated wastewater is then
pumped to a 1.7 million gallon aeration tank.
The aeration tank is provides the bulk of the treatment and is aerated by both a diffused
aeration system and a floating Biomixer® that injects air through submerged rotors.
ii'u i.t ► i w i

NPDES Permit Fact Sheet - October 7, 200,3
Page 4 1. -
DuPont Fayetteville
NC0003573
The aerated wastewater is sent to two in ground clarifiers operated in parallel. The clarified
effluent is finally discharged through internally outfall 001 which is ultimately discharged to
outfall 002.
3.2.2 Solid Train
The wasted sludge from the WWTP is sent to a dissolved air flotation unit, then to a 47,000
gallon sludge storage tank, and finally to a rotary filter for thickening. The thickened sludge
is dewatered in a screw press and then dried in a steam -heated dryer. The dried sludge is
transported off-site to a commercial landfill.
3.3 Compliance Summary
A compliance download was conducted from DWQ's Basinwide Information Management
System for the period January 2000 through August 2003. Three violations were noted for
BOD during that time period. One can conclude that the facility is generally very well
operated and maintained and remains in compliance with permit conditions.
4.0 PERMIT DEVELOPMENT
• Effluent Limitations: The large 7Q 10 flow of the Cape Fear River affords substantial dilution
of the facility's effluent. As such, this is very much an effluent limited permitting scenario.
Appropriate effluent guidelines have been applied using long-term average process
wastewater flows (see outfall summary above and the attached spreadsheets summarizing
guideline calculations).
• Instream Monitoring: This facility is a member of the Cape Fear River Basin Association.
This association manages the collection and submittal of instream water quality data for its
members. In recognition of this facility's participation, instream monitoring requirements
are waived until such participation is suspended. Should participation end, instream
monitoring requirements, articulated on the effluent limitations pages, will be immediately
reinstated.
5.0 OTHER ISSUES
5.1 APFO
APFO is recognized as a bio -persistent compound; it remains in the body or environment for
extended periods of time after exposure. DuPont claims that its medical surveillance of
employees and epidemiological data from others in industry support its conclusion that APFO
does not pose a health concern to humans or animals at levels present in the workplace or
environment.
DuPont has used APFO for more than forty years and claims to have never observed health
effects in workers. Furthermore, it is DuPont's assertion that the low volume usage poses
neither an acute nor a chronic risk. While not identified as a developmental toxin, human
carcinogen, or genotoxic compound, ongoing research is attempting to quantify the extent, if
at all, of APFO's toxicity.

5.2 BCH Energy Project
DuPont Fayetteville
NC0003573
BCH Energy entered into an agreement with DuPont a number of years ago to build a
cogeneration facility on DuPont's Fayetteville plant site. The cogeneration facility was
constructed and was intended to provide power to the grid and steam to DuPont. The project
went into bankruptcy in 1998, and the project's facility and equipment housed on DuPont's
plant site were sold. The facility is no longer in operation.
5.3 Outfall 002 Discharge Relocation
During a drought condition in the summer of 1999 the DuPont effluent channel conveying
the site's final wastewater discharge to the Cape Fear River experienced sloughing of the
streambanks into the flowing effluent, resulting in excessive sediment discharge to the river.
DuPont initiated a study to determine a cost effective remedy to the situation. The company
is currently considering two options.
Option 1 involves the relocation of outfall 002 via pipeline to the Cape Fear River upstream of
Lock & Dam U. Option 2 involves the relocation of outfall 002 via pipeline to the Cape Fear
River further downstream. Relocation of the outfall above the Lock & Dam would necessitate
a water quality/quantity modeling analysis. Such an analysis would certainly be considered a
relatively low priority at present given the scarce modeling resources available to the Division
and the number of TMDLs currently under development and on deck for development in the
near future.
