Subject: NPDES Permit Correction
Permit No. NC0003573
Fayetteville Works
Bladen County
Division personnel received your comments on the issued NPDES permit for the above
referenced facility and have corrected the permit accordingly. Specifically, the following
corrections have been made the attached permit:
• The facility name has been changed to "DuPont -Fayetteville Works".
• Reference to the Dymetrol process has been eliminated from the Supplement to
Permit Cover Sheet.
• Item number 4 on the Supplement to Permit Cover Sheet has been eliminated in
recognition of the lack of process wastewater from the APFO process (not outfall
007).
• Former item number 5 is now item number 4 on the Supplement to Permit Cover
Sheet and has been modified to eliminate any reference to outfall 007.
• The flow measurement location in condition A.(1) has been changed to "Effluent"
• Conditions A.(4) an
d A.(6) have been deleted in recognition of the elimination of
outfall 007.
• Former condition A. (7) is now condition A. (5) and has been modified to eliminate
any reference to outfa11007.
• The flow measurement location for new condition A. (5) -former condition A. (7) -
has been modified to read "Influent or Effluent" in recognition of the way that flow
has historically been measured for outfall 002.
• The sample type for fluoride in new condition A. (5) has been changed from grab to
composite.
• The sample frequency for conductivity in new condition A.(5) has been changed
from monthly to weekly.
• Instream monitoring for outfall 002 has been provisionally waived in recognition of
the facility's participation in the Middle Cape Fear River Basin Association. Note 1
on new condition A. (5) has been modified to reflect such.

• Former condition A.(11) - Outfall Warning Condition - now condition A.(9) has
been modified to allow the facility 30 days from the effective date of the permit to
post the outfall warning sign.
Regarding the effluent limitation for hexachlorobenzene, the US EPA adopted a new
criteria for this parameter during DuPont's previous permit cycle. As such, the allowable
concentration for hexachlorobenzene has lowered accordingly.
Compliance with all terms and conditions of the attached permit is Lite responsibility
A the Permittee. Please note that T15A 08G .0204 of the North Carolina Administrative Code
has been interpreted to mean that the Operator in Responsible Charge is responsible for
operation of water pollution control systems.
If any parts, measurement frequencies or sampling requirements contained in this
permit are unacceptable to you, you have the right to an adjudicatory hearing upon written
request within thirty (30) days following receipt of this letter. This request must be in the
form of a written petition, conforming to Chapter 150B of the North Carolina General

Nafion area streams are discharged entirely into the cooling water outfall, 002. Instream fluoride monitoring
shall be conducted monthly and shall coincide with effluent monitoring.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRACE
AMOUNTS.

Permit NC0003573
A. (6) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) — OUTFALL 001
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
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 Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase II 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 ChV 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 II 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 II 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 THP3B for the Chronic Value. Additionally, DWQ Form AT -3 (original) is to be sent to the
following address:
Attention: Environmental Sciences Branch
or Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/
physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC 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 toxi
city monitoring is required, the
permittee 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 Branch 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 monitori
ng 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 organ
ism
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.

Pern it NC0003573
A. (7) RE -OPENER CONDITION
This permit shall be modified, or revoked and reissued to incorporate additional toxicity limitations and
monitoring requirements in the event toxicity testing or other studies conducted on the effluent or receiving
stream indicate that detrimental effects may be expected in the receiving stream as a result of this discharge.
A. (8) BIOCIDE CONDITION
The permittee shall not use any biocide except those approved in conjunction with the permit application. The
permittee shall notify the Director in writing not later than ninety (90) days prior to instituting use of any
additional biocide used in cooling systems which may be toxic to aquatic life other than those previously reported
to the Division of Water Quality. Such notification shall include completion of Biocide Worksheet Form 101 and a
map locating the discharge point and receiving stream.
A. (9) OUTFALL WARNING CONDITION
Within 30 days of the effective day of this permit, the permittee shall post a sign along the wastewater
conveyance. This sign shall include language that indicates the channel to be an industrial wastewater
conveyance no recommended for recreational purposes. This sign shall also provide appropriate DuPont contact
information in the event members of the public have questions or concerns.

NPDES Permit Administrative Corrections
Subject: NPDES Permit Administrative Corrections
From: "Michael E Johnson" <[e-mail]>
Date: Thu, 29 Jan 2004 10:43:47 -0500
To: [e-mail]
Mark,
Per our telephone conversation last week, here are the administrative
corrections I request be made for our recently issued NPDES Permit.
rection 1 - Front page of permit, please change the name of this
L;Wof
facility from "DuPont Fluorocarbons" to "DuPont - Fayetteville Works".
C ection 2 - Second page of permit titled "Supplement to Permit Cover
Loo heet", please modify item number 2 to read: "Discharge treated process
wastewater from Butacite, Nafion, and Teflon(R) PMDF, process stormwater,
.movie The Dymetrol business has been physically moved from this site, and
the APFO Facility was constructed so as to have no process wastewater
discharges.
Co ection 3 - Second page of permit titled "Supplement to Permit Cover
eet", please eliminate item number 4 that refers to APFO wastewater
discharging through Outfall 007. As I explained above, the APFO Facility
was constr ted so as to have no process wastewater discharges.
Co ction 4 - Second page of permit titled "Supplement to Permit Cover
eet", please modify item number 5 to be item number 4, and then modify
the wording of that paragraph to read: "... and effluent from outfall 006
through outfall 002 at the location specified..."
rection 5 - In Section A.(1) which lists the limitations for Outfall
001, please change the Sample Location for the Flow parameter from
"Influent or Effluent" to "Effluent". Outfall 001 has a calibrated flume
which c ntinuously measures and integrates the flow rate through it.
stion - In Section A(2) titled Subpart I Requirements, the daily
aximum limit for hexachlorobenzene is listed as 0.5 ug/L whereas it was
1.41 ug/L in our previous permit. I just wanted to point this out in case
AJC it is a typo and should be 1.41 ug/L. Otherwise I assume that someone (EPA
or DWQ) decided that the water quality standard for hexachlorobenzene
needed to be lowered.
rrection 6 - Please eliminate Sections A(4) and A(6) since there is no
discharge of process wastewater from the APFO process.
Corr on 7 - In the narrative of Section A(7), please eliminate the
erence to APFO and Outfall 007. Therefore, that paragraph should read:
from Outfall 002 (boiler blowdown, once -through cooling water, treated
wastewater from Outfall 001, and Nafion low -biodegradable process
wastewat s from Outfall 006)."
rection 8 - In Section A(7), which lists the limitations for Outfall
002, please change the Sample Location for the Flow parameter from.
"Effluent" to "Influent or Effluent". Outfall 002 has no means of
measuring its flow rate. Therefore, our NPDES permit has always allowed us
to measure the amount of water pumped from the Cape Fear River and report
that as our Outfall 002 flow.
C ection 9 - In Section A(7), please change the Sample Type for the
luoride parameter from "Grab" to "Composite". This parameter has always
been a composite sample, and I cannot think of any reason for it to be a
grab.

NPDES Permit Administrative Corrections
the Conductivity parameter should be "Weekly" instead of "Monthly". The
old permit had it listed as weekly, and the other instream monitoring is
listed as "weekly".
Correctio - Section A(11) states that DuPont must post the Outfall
War g Sign "within 30 days of the issuance of this permit". The cover
tter is dated January 9, 2004, the envelope was postmarked on January 15,
2004, and I received the permit on January 19, 2004, meaning I received
notification of this requirement ten days after the issuance date. To give
us the time needed to design, create and install this sign, please change
Section A(11) to read "Within 30 days of the effective date of this permit,
.ratio We believe we can have the sign in place by the end of February.
Question - As a follow-up to the phone message I left you, should there
be language in the NPDES permit which states that the requirement to
perform instream monitoring is waived so long as this facility is a
recognized member identified in the Memorandum of Agreement between the
Division of Water Quality and the Middle Cape Fear River Basin Association,
and so long that the Association performs the instream monitoring specified
in the MOA? I heard the phone message you left me about facilities doing
some instream monitoring in addition to the coalition monitoring, and the
answer is that ALL instream monitoring is waived if a facility is a member
of one of the DWQ-recognized river monitoring coalitions.
I think that is all I found on the permit.
