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 permittee 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 minimum 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, 2006 for the renewal of its
NPDES permit. The DuPont Fayetteville Works manufacturing facility includes the Butacite® plant, the
Nafion® plant, the Teflon® plant, and the APFO plant. A new process will be added in 2007 to produce
Polyvinyl Fluoride (PVF) resins. The process wastewaters generated from the new facility will be treated in the
existing treatment plant. DuPont has requested to modify the permit to include the new process wastewaters
generated by the PVF manufacturing and to eliminate outfall 006 from the permit.
Manufacturing Facilities:
Buticite® Manufacturing
DuPontTm Buticite® Interlayer plastic sheeting — This is the final product used in safety glass such as
automobile windshields.
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 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.
Nation® Manufacturing
Five products are manufactured at the Nafion® manufacturing facility:
DuPontTm Nafion® membrane — a plastic film used in the chloroalkali industry and in
electrochemical fuel cells;
• 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 DuPont na Teflon&
• HFPO monomers — shipped to other DuPont locations to produce various fluorochemical products
such as DuPonfrm Teflon®.
Wastewaters generated at this facility are neutralized and treated in the on -site WWTP.
Teflon® Manufacturing
DuPontTm Teflon® FEP resin — this resin is used in the electronics industry as a coating for wire, as well as
many other uses.
Wastewaters generated at this facility are treated in the on -site wastewater treatment plant.
Ammonium Perfluorooctanoate (APFO) Manufacturing
APFO is used to produce fluoropolymers and fluorinated telomers that are shipped to other DuPont facilities.
Wastewaters generated in this process are collected and shipped off -site for disposal.
Sentry Glass Plus® 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-Outfali 002: - - --- ---- — ------ — -- ----- --- ---- - - -
Proposed PVF Manufacturing
This facility will produce Polivinyl fluoride resins (PVF) and is expected to start production in October 2007.
PVF is used in DuPontT"^ Tedlar® 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 wastewater generated at this site will be treated at the on -site wastewater treatment plant. Wastewater
from the PVF process will contain unreacted vinyl fluoride, with little or no BOD value. The expected
concentration of vinyl fluoride at outfall 0002 is 0.0035 mg/l.
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 consists of the following:
• Influent pump sump
• 850,000 gallon Equalization basin with two floating submerged mixers
• 250,000 aerated predigester tank
• 1,700,000 gallon aeration tank with a bottom diffused air system with supplemental floating mixer
that injects air through submerged rotors
• Two clarifiers
• 175,000 gallon emergency retention tank
• Dissolved Air Flotation Unit for sludge treatment
• 47,000 gallon sludge storage tank
• Rotary filter for thickening
• Sludge press and steam heated dryer
The treatment system discharges through Outfall 001 to the main discharge channel.
