Ceriodaphnia dubia at an effluent concentration of 3.3%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina CeTiodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions. The tests will be performed during the months of February, May, August, and November. Effluent
sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
If the test procedure performed as the first test of any single quarter results in a failure or Ch'%7 below the permit
limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months
as described in "North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998)
or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection
methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase 11 Chronic
Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the
pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the

Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration /response data, and be certified by laboratory supervisor and OR'C or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
pern-littee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at
the address cited above.
Should the pern-littee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality 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 rninimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an
invalid test and will require immediate follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.

Summary:
E.I. 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.

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.

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.

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 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.

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.

SUBJECT: Changes of Discharge of Toxic Substances
NPDES Pen -nit No. NCO003573
Dear Mr. Vinzani:
This letter is the written notification, as required by Part H[(C)(b) of the subject NPDES
permit, of the discharge of a pollutant from the DuPont h is
Company — Fayetteville Works, which
not limited in the permit.n h c
DuPont has determined that fluoromalonate is being discharged from the site' . s wastewater
treatment plant at a concentration exceeding the notification level of 0.50 mg/L specified in
Part HI(C)(b)(1) the NPDES permit. 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.
