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 NPDES Permit Fact Sheet - October 7, 2003 DuPont Fayetteville Page 3 NC0003573 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 Page 5 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. 6.0 PROPOSED SCHEDULE FOR PERMIT ISSUANCE Draft Permit to Public Notice: Permit Scheduled to Issue: 7.0 STATE CONTACT October 15, 2003 December 1, 2003 If you have any questions on any of the above information or on the attached permit, please contact Mark McIntire at (919) 733-5083, extension 508.

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 NPDES Permit No. NC0003573 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.

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.

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 64% 25% 8% 3% Trace Trace E. I. du Pont cle Nemours and Company ®Printed on Recycled Paper FL -4 Rev. 6/99 Mr. Michael Templeton NCDENR —Division of Water Quality August 27, 2002 Page 2 of 4 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 Mr. Michael Templeton NCDENR —Division of Water Quality August 27, 2002 Page 3 of 4 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. Mr. Michael Templeton NCDENR—Division of Water Quality August 27, 2002 Page 4 of 4 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. If you have any questions, please feel free to call me at (910) 678-1155.
