Afternoon Paul. Wanted to get some more specific input from you about
the sign that we're going to require DuPont to post. Can you take a
crack at some language? I'd propose using the expression Wastewater
Conveyance in lieu of Effluent Channel.
Hope you have a great Thanksgiving. Be safe on the roads.

2.0 BACKGROUND
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 #3.
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 60oF. 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, nafiop, 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 chloroalkali 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 TeflonO 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 APFO
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

S.O 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
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 an
d is aerated by both a diffused
aeration system and a floating Biomixer0 that injects air through submerged rotors.

NPDES Permit Fact Sheet - October 7, 2003
Page 4
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.
rj.0 OTHER ISSUES
5.1 APFO
APFO is recognized as abio-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.

NPDES Permit Fact Sheet - October 7, 2003

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.

DuPont - Fayetteville Works NPDES Permit No. NC0003573
Potential Facility Changes
APFO Manufacturing: The DuPont — Fayetteville Works has been tentatively identified as
the location for the DuPontTM APFO manufacturing process. This process will produce
ammonium perfluorooctanoate (APFO), CAS No. 3825-264, an essential raw material for the
DuPontTM Teflon® fluoropolymer resins business. The manufacturing unit will be located either
near the existing Dymetrol© manufacturing building or near the Nafion® area's Vinyl Ethers
South manufacturing building.
APFO is recognized by DuPont and others as a biopersistent compound, meaning it remains
in the body or environment for extended periods of time after exposure. Due in part to APFO's
biopersistence, DuPont, alone and in collaboration with others, has made considerable
investment into studying potential health effects of APFO. DuPont's medical surveillance of its
own 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 with no observed health effects in workers.
APFO is used in low volumes and does not pose any significant acute or chronic risk. It is not a
genotoxic compound. It is neither a known developmental toxin nor a known human carcinogen.
APFO exhibits low environmental toxicity; tests on various aquatic life forms have shown no
adverse effects even at very high doses. APFO is not bioaccumulative in the food chain.
As with most fluorochemical processes, the wastewater from the APFO manufacturing
process is expected to have very little or no biological oxygen demand (BODS) value. In
addition, the fluoride and fluorocarbons have been related to settleability problems in the
WWTP's final clarifiers. For these reasons, DuPont proposes to create a new permitted outfall,
designated as Outfall 007, with the same monitoring requirements as the currently permitted
Outfall 006, through which the APFO process wastewater will be discharged directly to the site's
woodlined ditch and ultimately through Outfall 002. The rational behind this new outfall is
identical to that used to create Outfall 006 (See Attachment A for a letter dated March 15,1996
from Michael E. Johnson, DuPont, to Gregory Nizich, DEM).
DuPont will conduct a study of the APFO process wastewater to verify the absence of
significant BODS value before the project is constructed to provide support for the
appropriateness to discharge of this stream directly to the woodlined ditch. In the extremely
unlikely event that this wastewater exhibits BODS concentrations near the permitted limit of
24 mg/L, then DuPont will convey the wastewater to the site's WWTP for treatment and
discharge at Outfall 001.
The APFO wastewater will contain iodide, a new chemical to the Fayetteville Works facility.
Current estimates of the wastewater indicate that there will be approximately 365 lb/day I2 that
would convert to form approximately 477 lb/day of the potassium iodide salt (KI). The 7Q10 of
the Cape Fear River at the DuPont location is 791 cubic feet per second. At the 7Q10 flowrate,
the concentration of potassium iodide in the river would be 112 µg/L.
An emergency oleum water scrubber will be included as an integral part of this process. =In
the unlikely event of a release of oleum (a solution of S03 in H2SO4) inside the manufacturing
building, the scrubber would remove the resulting S03 from the air. To prevent the growth of

DuPont - Fayetteville Works

Potential Facility Changes
algae and/or slime inside the scrubber, a biocide will likely be added to the water in the scrubber.
There will be a purge of some volume of the scrubber water on a continuous basis, so the biocide
will be discharged to Outfall 002. At this time, no decision ,has been made as to what biocide
will be used in this scrubber, but when one is chosen, DuPont will submit a revised Part 5 to
Section II of this application for Outfall 002 and Outfall 007.
Finally, stormwater associated with the APFO process area will be discharged directly to
Outfall 002 via the site's Woodlined Ditch.

Dear Mr. Johnson:
After consulting with our aquatic toxicology staff and staff from the Division of Waste Management's hazardous
waste program, the Division of Water Quality has reviewed and approved your request to discharge the DMSO waste
stream from the Nafion® Products manufacturing area to the wastewater treatment system with subsequent discharge
through outfall 001. It is the determination of this office that modification of the NPDES permit is not necessary as the
existing permit provides sufficient coverage and protection to accommodate the DMSO waste stream.
If you have any comments, questions, or concerns regarding this matter, please do not hesitate to contact me at

SUBJECT: Addition of New Waste DMSO Stream to DuPont WWTP
NPDES Permit No. NC0003573
Dear Mr. Templeton:
t 27, 2002
This letter requests that the Division of Water Quality make a determination as to whether the
DuPont —Fayetteville Works can begin treating a new wastewater stream in its Wastewater
Treatment Plant (WWTP) without a modification of the subject NPDES Permit, or if such a
change would require a modification of said permit.
It is my belief that this insignificant change would not necessitate a permit modification. I hope
that after you read this letter you will agree with that conclusion.
WASTEWATER DESCRIPTION
The wastewater stream in question is the Waste DMSO that is generated in the Nafion® Products
manufacturing area. This waste stream is a RCRA hazardous waste due to its corrosivity
characteristic, meaning that it has a pH greater than 12.5 SU. The Waste DMSO is currently
shipped off-site to the DuPont Chambers Works facility in Deepwater, New Jersey, for disposal
in their NPDES permitted wastewater treatment plant.
The waste stream, which is estimated to average five (5) gallons per hour, would be a small
fraction of the WWTP influent flowrate of approximately one million gallons per day (1 MGD).
The composition of the wastewater stream is as follows:
Water
Potassium hydroxide
Dimethyl sulfoxide
Potassium fluoride
Methanol
Phenols

Dimethyl Sulfoxide (DMSO)
The major organic compound in this wastewater stream is dimethyl sulfoxide (DMSO) with a
AS Number of 67-68-5. DMSO is a simple organic compound with the following structure:
O
11
CH3 — S — CH3
DMSO is a common compound, with is most familiar application being as a pharmaceutical
agent used for a variety of ailments, including pain, inflammation, scleroderma, interstitial
cystitis, and arthritis elevated intercranial pressure. It obviously has a very low mammalian
toxicity level, with an oral LD50 of 17,400 mg/kg body weight and a NOEL of 1,100 mg/kg/day
for rats. It has a dermal LD50 of 40,000 mg/kg body weight for rats.
DMSO has an extremely low aquatic toxicity. The LC50 (96 hrs.) for ten species of fish range
from 32,500 to 43,000 ppm. The LC50 for two species of protozoans are 32,000 and 38,000 ppm.
The concentration required to inhibit growth (EC50) for five species of blue-green algae and one
green algae species ranged from 0.4% to 4.0%. DMSO is non-bioaccumulating since the log of
the octanol/water partition coefficient is 4.35.
The existing Waste DMSO Storage Tank in the Nafion® manufacturing area will continue to be
used to store the Waste DMSO and will act as a large holdup tank. The waste stream is
generated batchwise, with as much as two months between the generation of batches. The
storage tank will allow this waste stream to be added slowly and consistently to the WWTP at an
anticipated rate to five (5) gallons per hour.
At the five gallon per hour rate, there would be approximately 80 lb/day of DMSO entering the
WWTP. At our usual influent flow rate of one MGD, the concentration of DMSO in the
influent would be 9.6 mg/L (9.6 ppm) as DMSO. We anticipate that after a brief acclimation
period for our bacteria, that the majority of the DMSO will be biologically degraded in the
WWTP. However, even if there were no degradation of the DMSO in the WWTP, the
concentration at the Outfall 002, with an average flowrate of approximately 12 MGD, would be
0.8 ppm, which is substantially less than the toxicity levels states above.
DMSO is not a regulated chemical in either federal or state regulations.
Potassium Hydroxide (KOH)
The potassium hydroxide (KOH) is listed as a hazardous substance with a reportable quantity of
1,000 pounds per day. There will be 250 pounds per day as KOH leaving the Nafion® process.
However, it will either be neutralized prior to introduction into the WWTP, or it will be
neutralized within the WWTP, with the result of the KOH being converted to potassium sulfate

and water. Potassium sulfate is not a regulated substance. There is an effluent limitation
guideline for the production of potassium sulfate, but the only two limited pollutants are TSS and
pH, which are already limited by the subject NPDES permit.
Potassium Fluoride (KF)
Potassium fluoride is not a regulated chemical in any federal or state regulation.
Methanol and Phenol
Both methanol and phenol are present in the Waste DMSO in trace quantities. The natural
commingling of the subject waste stream with other wastewaters in the WWTP will result in the
methanol and phenol being at non-detectable levels entering in the WWTP influent, and exiting
from Outfall 001 if they were to pass unaltered through the WWTP.
WASTE HISTORY
The Waste DMSO has been generated at this site for many years. When the Nafion® process
started up in 1980, an attempt was made to treat the Waste DMSO in the on-site WWTP. At that
time, the waste stream was sent batchwise from the Nafion® area, which resulted in
approximately 6,000 gallons of Waste DMSO entering the WWTP over a day period, followed
by two months of no addition of this waste. This cyclic pattern is not a good means of treating a
pollutant in an activated sludge WWTP.
Also at that time, the WWTP only had the current Equalization Basin as the aeration unit, using
floating surface aerators. This system unintentionally created areas with no aeration, in which
anaerobic bacteria existed that degraded the DMSO to hydrogen sulfide. When the surface
aerators would contact these dead areas, the hydrogen sulfide would be released to the
atmosphere resulting in unacceptable odors.
Because of this odor problem, the Waste DMSO was collected and then transported to the
DuPont —Chambers Works facility in Deepwater, New Jersey, where it was treated in their
larger, more efficient WWTP.
Per your request, the DuPont contact at the Chambers Works facility is Mr. Leo Karwaski.
Mr. Karwaski is the New Jersey licensed operator of the Chambers Works WWTP and can
answer any and all of your questions regarding their treatment of this waste stream. His direct
phone number is 856-540-2760.
Since the 1970 time period, the Fayetteville Works site's WWTP has been expanded and
improved, and the WWTP areas that harbored the anaerobic bacteria have been eliminated. The
DMSO should be easily biotreated aerobically without issue or concern.

RATIONAL FOR THE CHANGE
In 2001, the DuPont - Fayetteville Works transported 232,000 pounds of the Waste DMSO by
highway to the DuPont facility in Deepwater, New Jersey, for disposal in that facility's WWTP.
The annual transportation cost to transport this waste 450 miles is approximately $10,800. In
addition, the waste is RCRA characteristically hazardous due to its corrosivity. Treating the
waste stream on-site is the best option from both a financial standpoint for DuPont and from a
highway safety standpoint.
SUMMARY
The Waste DMSO is successfully treated in an NPDES permitted activated sludge WWTP in
New Jersey, Over 200,000 pounds per year are shipped to the New Jersey facility, resulting in a
transportation cost of over $10,000 per year and the always possible transportation incident with
this characteristically hazardous waste.
The DuPont —Fayetteville Works wishes to begin treating this waste on-site in the activated
sludge wastewater treatment plant.
The Waste DMSO does not contain a regulated compound that would require a new permitted
parameter to the subject NPDES wastewater discharge permit. The appropriate parameters of
concern for this waste stream, specifically pH, BODS, and TSS, are already existing on the
current permit. DuPont is not seeking any increases to the existing permitted limitations as a
result of this new waste stream.
