A- i , I i.'.1 NPDES Permit Fact Sheet - October 7, 2003 Page 2 •- 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 NPDES Permit Fact Sheet - October 7, 2003, DuPont Fayetteville Page 3 NC0003573 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. 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: October 15, 2003 Permit Scheduled to Issue: December 1, 2003 7.0 STATE CONTACT 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.
