FACT SHEET FOR WASTELOAD ALLOCATION Wasteload Allocation Summary (approach taken, correspondence with region, EPA, etc.) The Fayetteville facility has two main process areas: 1) Butacite and PVB intermediates and 2) Nafion and perfluoronated intermediates. Currently, both process waste streams go through the treatment plant and are discharged via Outfall 001. DuPont is proposing to route the Nafion stream around the waste treatment plant because the only significant pollutant in it is fluoride which is not removed in the treatment process, so the Nafion stream only constitutes extra hydraulic loading that lowers retention time in the plant for the treatable PVB waste stream. The Nafion stream would have to re-enter the Outfall 001 stream prior to the OCPSF sampling and limitation point or such requirements will have to be applied to it separately. Only minor changes are recommended for this rengv al. Updated application of federal effluent guidelines will cause a slight reduction of BOLD„limits for this renewal. TP/TN monitoring requirement has been shifted to Outfall 002 in order to measure nutrient loading to the river. Please also note the addition of instream monitoring requirements.

The North Carolina Cerigdahnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is a._a_% (defined as treatment two in the North Carolina procedure document). The permit holder shall perform gy r monitoring using this procedure to establish compliance with the permit condition. The first test will be performed after thirty days from the effective date of this permit during the months of A-11, _ _ Effluent sampling for this testing shall be performed at the NPDES permi�al efifient discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR -1) for the month in which it was performed, using the parameter code TGP3B. Additionally, DEM Form AT -1 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy Creek Road Raleigh, N.C. 27607 Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will revert to quarterly in the months specified above. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival and appropriate environmental controls, shall constitute an invalid test and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute noncompliance with monitoring requirements. 7Q10 ?`1l cfs Permitted Flow 17 MGD IWC 3. 2 % Basin & Sub -basin 03-o('-1 Receiving Stream Ca e� County Al adc k QCL PIF Version 9191 Recommended by: f' r V OM Go co CD WODOD'*wm0C+ 0m 0CDw0 000 NdOdMd dr-0M0NCD V M V r O V V M M V M O M O O O Ol O M N O O) r V P r CD CD CD M d P CD P CD Ol t p a r W N r O V V r r r r �D r N M N O r r N O r r P CD N r N N r r r N V d 0 O C0 9 O O O Q O O O O O Q O O O O O O O Q O O r 0 0 O r O 0 0 0 0 0 Q 0 0 0 0 0 Tom, >,TTT >. �.T T�.TTTTTT TT�.T TTTT>.T TT�.T �+T >wTTT lb 0 0 f0 N td C !d c0 a � 0 a l0 0 l0 l0 l0 0 0 Itl A N a l0 !d td D !d lb O D CC etl N 0 /0 0 'O 'O � 'C) v R7 � 'O � 'C 17 17 'O 9 'O 'O v 17 'Cf �_ 'Cf 9 � 'O 'C 'C7 � � � 'O 17 � v 'fl 'O 'O 'C 'O �O POMCA V lArQddPdONMOIAddd1AOCAm POI CD V PNPCDMdPl7Dr W O dD CA d Cp r CO LD IA W 1A N O V P CD N CD Ln M r lD M P O O d CO V N CD V CD O r P M Cn O N r a V M M Ch M M P M CD O N r r M P N N N O N P d to N M M V d O Cb O r O r O O O O r r O O O O r O O r O O O O O r O O r V O O O r O O O O O +LL LL O r O w LL LL LL LL LL E r6aaa zaoTC�Ca�CaN��aaaaCa��aaaaaCa(aJta�aaaa(a�ii( 888888.8888888888888888888888888888888 t N O N cm 'aFQCv�j E! -E ' E0 cm E�QFD EEC p�ppg 22�oZti Nc C9 .2 AA E E FEF E E FEF E F E E E FEF E E E E E E E E F E E 22 I13 3 11 13 11 311133 9 Or_ CO CO rO- gggggggggggg�g ����g������ 's Ewo Ngg �gg P P co n a a x a m a in a m m a m a m a a a m a a m a a o a m a m a a a m g���< ��c�g�cOrrOg�gC�� S o E E ° 0 0 8$$ $$ E$ o S E 0 E$ E E 8 0 0 N N C n r EEE L E E F F E E E L F E E E E E E E E E E E E E$ E E E E E E E E E E E o�$a��a�sa�� m m m a a a a a a a m m a a a m a m m a a a a a a a a a a a a taL LL N Cn tUL IUl LL lL I�ULp t�ULp aLL pp LL LL �p LL LL LL lL IL IUL IpULp (pLL LL LL LL LL LL LL U0 LL LL LL LL LL LL LL LL LL a 9 VIM ��Opp ?

Box 29535 Raleigh, NC 27626-0535 RE: Renewal of NPDES Permit No. NC0003573 Analysis for bis(2-Ethylhexyl) phthalate at Outfall 001 Dear Mr. Doll, Enclosed are the analytical results from the two most recent Outfall 001 analyses for bis(2-Ethylhexyl) phthalate which shows that this compound was below the method's detection limit. These results should verify that the analysis of 81 µg/L bis(2-Ethylhexyl) phthalate at Outfall 001, as reported for the 1995 OCPSF Priority Pollutants annual monitoring, was probably from cross -contamination of the sampler's synthetic rubber gloves. As we have discussed, this site has never purchased nor manufactured, as products or by-products, any of the phthalates. If you have any questions, please feel free to call me at (910) 678-1155.
