DuPont de Nemours & Co submitted a permit renewal application on May 2, 2011 for the renewal of its NPDES permit. The DuPont Fayetteville Works manufacturing facility includes the Butacited plant, the Nafion® plant, the Teflon® plant, and the APFO plant. A new process was added in 2011 to produce Polyvinyl Fluoride (PVF) resins. The process wastewaters generated from the new facility will be treated in the existing treatment plant. Manufacturing Facilities: Buticite RO Manufacturin • DuPontTM Buticite® Interlayer plastic sheeting — This is the final product used in safety glass such as automobile windshields. Butacite® is manufactured in large rolls and shipped out in refrigerated trucks to glass manufacturers. The refrigeration is a requirement as Butacite sticks to itself at temperatures above 60°F. • Polyvinyl butyral (PVB) resin - the resin is shipped to other DuPont facilities for final processing. Wastewaters generated at this facility are treated in the on -site wastewater treatment plant. Nafion® Manufacturing Five products are manufactured at the Nafion R manufacturing facility: • DuPontTNz Nafion® membrane — a plastic film used in the chloroalkali industry and in electrochemical fuel cells; Fact Sheet NPDES NCO003573 Page 1 DEQ-CFW 00081304 • Nafion® resins — ultimately extruded into a finished 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 DuPontTnl Teflon®. • I-IFPO monomers — shipped to other DuPont locations to produce various fluorochemical products such as DuPontTM) Teflon®. Wastewaters generated at this facility are neutralized and treated in the on -site W\X/TP PPA Manufacturing The processing aids produced in this units are used to produce fluoropolymers and fluorinated telomers that are shipped to other DuPont facilities. This facility was started up in November 2002. Wastewaters generated in this process are collected and slipped off -site for disposal. Sentry Glass Plus(R) Manufacturing DuPontTM Sentry Glass Plus© - this is an ionoplast interlayer laminate used for laminated safety glass in side, rear, and overhead automobile windows. It is also used in architectural applications desiring safety glass. This manufacturing process started in June 2005. No process wastewaters are generated from this process. Non - contact cooling water is discharged to Outfall 002. Proposed PVF-3 Manufacturing This facility will produce Polivinyl fluoride resins (PVF) and is expected to start production in 2013. The manufacturing facility will be located near the existing PVF-1 and PVF-2 manufacturing processes. PVF is used in DuPontTM TedlarO fluoropolymer film manufactured at other DuPont facilities. Tedlar® is used in the photovoltaic industry in photovoltaic cells and the aircraft industry for interior cabin surfaces, as well as other uses. The PVF-1 facility began operation during September 2007, the PVF-2 facility began operation during June 2010. Process wastewater generated from this manufacturing facility is treated in the WWTP. Non -contact cooling water, condensate and stormwater will be discharged to Outfall 002. Wastewater Treatment: Process wastewaters and stormwater from process areas are collected in sumps in the respective manufacturing areas and conveyed via gravity sewers to the wastewater treatment plant. Sanitary sewage is conveyed separately to the WWTP. The treatment system discharges through Outfall 001 to the main discharge channel. Non -process cooling waters and stormwater are conveyed to ditches and discharged to the main discharge channel. The combined flows are discharged through Outfall 002 to the Cape Fear River below Lock and Dam #3. Effluent Guidelines: DuPont's Fayetteville Works is regulated under the Organic Chemicals, Plastics and Synthetic Fibers Category, 40 CFR 414 Subpart D. These guidelines apply to products manufactured under SIC codes 2869 and 2821. SIC code 2869 includes Nafion® solution, Vinyl Ether and HFPO monomers manufacturing. SIC code 2821 includes Teflon® resin, polyvinyl fluoride resin, polyvinyl butyral resin and NafionO resin manufacturing. Manufacturing of Nafion membrane, ButaciteO sheeting and Sentry Glass plus are classified as SIC code 3081 which is not regulated by the OCPSF guidelines. Regulated process flow for Outfall 001 is approximately 0.9 MGD. This flow includes the flow from PVF manufacturing process. EG limits - Subpart D - Thermoplastic Resins, 414.41 Limits are calculated by multiplying the allocation from the effluent guidelines by 8.34 (conversion factor) and by OCPSF process flow. Fact Sheet NPDES NCO003573 Page 2 DEQ-CFW 00081305 Limits are calculated by multiplying the allocation from the effluent guidelines by 8.34 (conversion factor) and by OCPSF rocess flow.

Receiving stream or affected surface waters: Cape Fear River a. Classification: Class C b. River Basin and Subbasin No. Cape Fear River Basin 03 - 06 - 17 Describe receiving stream features and pertinent downstream uses: Treated wastewater from Outfall 001 flowed into a board lined ditch, which contained the boiler blow -down from DuPont, the once -through cooling water, and the filter backwash that was discharged to the Nafiong ditch, Approximately 50 to 100 feet downstream of where Outfall 001 flow commingled with the flow that was in the board lined ditch, the flow passed under a board deck that supported the Outfall 002 compositor. For compliance monitoring of samples for chronic toxicity, and according to the NPDES permit, the samples were taken downstream of the confluence of outfall 001 and the flow that was in the board lined ditch. This sample point was Outfall 002. The Cape Fear River was located approximately 2,500 feet downstream. (The discharge point has historically been indicated as the main stem of the Cape Fear River.) An A to C (ATC # 003573A02) was being processed for the relocation of Outfall 002 to the Cape Fear River at a location upstream of Lock and Dam No. 3 PART H - DESCRIPTION OF WASTES AND TREATMENT WORKS 1. a. Volume of wastewater to be permitted: 2.0 MGD b. What is the current permitted capacity of the Wastewater Treatment facility? 2.0 MGD C. Actual treatment capacity of the current facility (current design capacity). 2.0 MGD d, Date(s) and construction activities allowed by previous Authorization to Construct issued in the previous two (2) years. 1.) On July 15, 2008, plans were approved by Steve Coffey for the building Clarifier #3. 2.) ATC # 003573A02 was for the relocation of Outfall 002 e. Please provide a description of existing or substantially constructed wastewater treatment facilities: Process wastewater and storm water from the various manufacturing areas were 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 was conveyed via a separate underground sewer system to the WWTP. The permitted flow rate of the WWTP was 2.0 MGD, with an actual average flow rate of less than I MGD. This process wastewater was commingled in the WWTP Influent Sump where it was pumped to an 850,000-gallon Equalization Basin. The Equalization Basin was mixed with two floating mixers. Three floating surface aerators in the basin cool and aerated the incoming wastewater. A 175,000-gallon Emergency Retention Tank was available for temporary storage of the wastewater which may need additional treatment or acclimation in the WWTP activated sludge process at a controlled rate that allowed for proper biological treatment. Wastewater from the Equalization Basin was normally pumped to a 250,000-gallon Predigester Tank in which initial biological activity with the WWTP activated sludge begins. The Predigester Tank was aerated. The partially treated wastewater from the Predigester Tank was pumped to a 1,700,000-gallon Aeration Tank, The Aeration Tank was the site of the majority of the biological activity, The Aeration Tank was aerated primarily by a diffused air system located in the bottom of the tank. DEQ-CFW-00081326 DEQ-CFW 00081327 PART H - DESCRIPTION OF WASTES AND TREATMENT WORKS-(continue4M 0 11 The biologically treated wastewater was then sent to two in -ground clarifiers (119,000 gallons and 168,000 gallons respectively) in parallel. The clarified treated effluent was discharged to and through Outfall 001. The wasted sludge was sent to a Dissolved Air Floatation (DAF) unit, then to a 47,000 gallon Sludge Storage Tank, and finally to a Rotary Filter for thickening. The thickened sludge was dewatered in a Sludge Press and dried in a steam -heated dryer for additional moisture removal. The dewatered and/or dried sludge was transported off -site to a commercial Subtitle D landfill. Non -contact process cooling water and non -process storm water were conveyed via surface ditches to the site's wood lined ditch. In addition, Outfall 001 effluent was discharged directly to the wood lined ditch. The combined, total flow of water from the site was discharged at Outfall 002. The Outfall 002 maximum 30-day average flow was 18.1 MGD during the period from 2009-20 10. Flow variability at Outfall 002 was from 7.5 to 18.1 MGD. Please provide a description of proposed wastewater treatment facilities: 1) the relocation of the Plant Outfall 002 (ATC # 003573A02), 2) the addition of Clarifier #3. 9.

Alternative Analysis Evaluation: Has the facility evaluated all of the nondischarge options available? Please provide regional perspective for each option evaluated, Spray Irrigation: Not practical, Connection to Regional Sewer System: None Available. Subsurface: Not practical. Other disposal options: None known. Other Special Items: There were 7 items of interest that the Fayetteville Regional Office would like to be reviewed and modified, if appropriate. a. "C8" compound (perfluorooctanoic acid, APFO) is currently manufactured at the Fayetteville DuPont Works in a separate PPA manufacturing building (for fluoropolymer processing aids). All wastewater generated from this manufacturing facility is collected and shipped off -site for disposal. No process wastewater from this manufacturing facility is discharged to the site's biological WWTP or to the Cape Fear River. Due to C8 being detected in some of the monitoring wells on DuPont's site and the general public's concern over the health effects of C8 (see attached letter from North Carolina C8 Working Group, dated May 5, 2006), the Fayetteville Regional Office of the Division of Water Quality recommends the continuation of the monitoring requirement for C8 on the effluent for data collection and information purposes. The APFO results were 0.22 lig/1- in May 2009 and 0. 19 [tg/L in November 2010. b. All discharges from this DuPont site ultimately flow into the wood lined ditch, which collectively discharges into an effluent channel that flows to the Cape Fear River. Over the years the flow of the effluent through the channel has significantly eroded the banks and has carried and deposited the sediment in the Cape Fear River forming a Delta -like structure. DuPont acknowledged that their effluent channel has and continues to cause sediment to be deposited into the Cape Fear River, DuPont's Plan -Of -Action to address this issue is for the relocation of Plant Outfall 002 (ATC # 003573A02). c. According to the NPDES Permit Renewal Application letter dated April 29, 2011: "This site is being considered for a project to construct and operate a third manufacturing facility that will produce polyvinyl fluoride ("PVF") polymer resins. Two water balances are included in the application: one without the third PVF facility and one with the third PVF facility." d. Please see the enclosed letter (dated December 5, 2007) from Michael Johnson to Gil Vinzani concerning fluoromalonate concentration as high as 0.97 mg/L, because it may be of concern in Part III, Section C, b of the NPDES permit. DEQ-CFW-00081330 DEQ-CFW 00081331 e. Please review the Whole Effluent Toxicity sampling location that requires that the "compliance monitoring point for chronic toxicity shall be downstream of the confluence of outfall 001 and 002". This does not appear to agree with the Outfall 002 limits page which says that "the Permittee is authorized to discharge from Outfall 002 (boiler blowdown, once -through cooling water, and treated wastewater from outfall 001)". By this description, Outfall 002 is located below the confluence of outfall 001 and the flow from the wood lined ditch. f. It appears that the 3.3% IWC that is used for the Whole Effluent Toxicity Pass/Fail dilution was derived by using the sum of the total volumes that are in Outfall 002 "(boiler blowdown, once -through cooling water, and treated wastewater from outfall 001)" in the calculation, along with the 7QI0 for Cape Fear. Please review the sample point that requires Whole Effluent Toxicity testing, because it appears to be more applicable to Outfall 002, instead of Outfal 100 1 [as is presently in the permit, in the Outfall 001 limits page and in Part 1, A.(4) ]. g. Please change the description of the wastewater treatment facilities to three clarifiers (from the presently stated "dual clarifiers") because a third clarifier was recently built and put on-line, h. Please include wording in the new permit concerning the requirement for a flow meter located at the Outfall 002, because ATC#003573A02 for the relocation of Outfall 002 did not mention a flow meter. During the Compliance Evaluation Inspection on February 17, 2011, Mike Johnson verbally told Dale Lopez that the relocated Outfall 002 would have a flow meter. Presently, the influent flow from the Cape Fear River water intake is used in the flow measurement calculation for Outfall 002. The Cape Fear River influent flow measurement device is located on a 42-inch pipe, and the influent flow is measured by a Rosemont 1151 DP (Differential Pressure) flowmeter (venture type). The possible sources of flow measurement error when using the influent flow values for the estimated effluent flow from this facility to the Cape Fear are as follows: 1) the effect of evaporation loss within the entire DuPont facility, 2) the effect of infiltration, 3) the use of purchased potable water that flows thru the WWTP, and 4) the influence of the storm water volume from a rain event. I The Fayetteville Regional Office recommends that the DuPont WWTP be reissued NPDES Permit No. NC0021636. The subject application for permit renewal should be processed in keeping with basin wide strategy.

Recent analysis of the treatment plant's clarifier effluent showed the fluoromalonate concentration as high as 0.97 mg/L. The compound being discharged from the treatment plant would likely be monopotassium fluoromalonate (CAS No. 3107-37-9) or dipotassium fluoromalonate (CAS No. 3107-37-7). Depending on the pH, the compound in the Cape Fear River would be either fluoromalonic acid (CAS No. 473-87-0), monopotassium fluoromalonate or dipotassiun-i fluoromalonate.
