Dear Mr. Ferguson:
In accordance with your application for discharge permit received on October 31, 1989, we are
forwarding herewith the subject State - NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the US Environmental Protection Agency dated December 6, 1983.
In response to comments raised at a meeting between DuPont representatives and Division staff on
March 9, 1994, and a DuPont letter of March 14, 1994, regarding the draft permit, the following
modifications/comments are offered:
Outfall 001 -
• Ammonia Limits - These have been deleted. Monthly monitoring will be required.
• Nitrogen - This parameter cannot be dropped. DEM policy requires effluent monitoring for
nitrogen at all facilities discharging to NSW waters.
• Fecal Coliform - The instream monitoring requirement has been replaced by effluent
monitoring. When monitoring was dropped in 1985, the State water quality standard for fecal
coliform was 1000/100 ml. Since the standard is now 200/100 ml, existing data needs to be
reevaluated after a minimum of 12 months of data are collected.
• Additional sampling if the Monitoring Coalition does not materialize - Justification for the
added sampling that could be added to the permit will be provided if the Coalition does not
material i 7e.
• Instream DO monitoring - For major discharges close to a freshwater -estuarine interface,
DEM's model predicts the lowest instream DO's to occur. Also, the instream data is
necessary in this river segment to evaluate Dupont's affect(s) as it relates to the cumulative
impacts of wastewater discharges to the upper reaches of the river.
• Chronic Toxicity ronitoring frequency - This has been corrected to quarterly.

An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper

Outfall 001(continued) -
• Compliance for OCPSF parameters with limits below detection level - Split samples may be
taken to determine if lab error is the cause of detection rather than actual presence in the
wastewater. If this procedure is followed, sampling results would have to be averaged with a
result of non -detection averaged as zero.
• Metals sampling - Monitoring for metals must be conducted in the permit. Sampling
frequency has been changed to quarterly for these parameters.
• Feasibility study of achieving tertiary treatment - It is only necessary to document the
modifications, if any, and costs necessary meet this level of treatment.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicative 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 Statutes, and filed with the Office of
Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless
such demand is made, this decision shall be final and binding.
Please take notice this permit is not transferable. Part II, E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirements to obtain other permits which may be required by
the Division of Environmental Management or permits required by the Division of Land Resources,
Coastal Area Management Act or any other Federal or Local governmental permit that may be
required.
If you have any questions concerning this permit, please contact Mr. Greg Nizich at telephone
number 919/733-5083.

E. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia 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 1.9% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly 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 January, April, July and October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent 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.
F. This permit may be modified, or revoked and reissued to change the effluent limitation on
nutrients for this discharge depending upon the following:
1. The findings of a study by the Division of Environmental Management determine nutrient
control is necessary.
2. Local actions do not successfully reduce the nutrient loading on the receiving waters.
3. The onset of problem conditions in the receiving waters.

G. The permittee shall not use any biocides 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 Environmental Management. Such
notification shall include completion of Biocide Worksheet Form 101 and a map locating the
discharge point and receiving stream.
H. Reduced instream monitoring has been included in this NPDES permit under the assumption
that the Neuse River Coalition will be formed and approved by the Division of Environmental
Management. If the coalition does not materialize or you choose not to participate, the NPDES
permit may be reopened by administrative letter to include additional instream monitoring
requirements determined to be necessary to adequately characterize the effects of the discharge on
the Neuse River Basin's water quality.
I. Reduction in Monitoring Frequency for OCPSF Parameters
After monitoring for a minimum of a three year period, upon written request, OCPSF monitoring
data will be reviewed by the Division of Environmental Management to determine if a reduction in
monitoring frequency is warranted. Data submitted for review should be in a tabular format for the
sampling period under consideration.
J. When an approved analytical protocol with the appropriate minimum detection level is followed
and a result of "non -detectable" or "below quantitation limit" is obtained, the permittee will be
considered to be in compliance with the numerical permit limit for that pollutant.
K. Engineering Analysis
This discharge is located on the Neuse River mainstem which has limited assimilative capacity.
Discharges to the mainstem of the River must make efforts to treat to advanced tertiary levels, (i.e.
5 mg/1 BOD5 and 2 mg/1 NH3-N). Therefore, an engineering analysis evaluation the cost
feasibility of achieving advanced tertiary levels is due by February 1, 1997. If advanced tertiary
levels cannot be met with state of the art treatment for this industrial type, then information should
be provided detailing the best achievable levels of treatment.

DuPont's Comments on Draft Permit
DuPont - Kinston
Permit # NC0003760
Lenoir County
The following issues were mentioned by DuPont. We need to discuss them with DuPont
on March 9:
Outfall 001 (process)
1) Temp monitoring and DO - is the instream monitoring necessary?.
2) NH3 - what is basis of limits? I think this was part of the permit prior to effluent
guidelines being established.
3) Metals monitoring - What was the basis for monitoring for these parameters? Can the
monitoring requirements be handled outside the permit via a 308 letter?
4) Special Condition for Neuse Coalition - How does it relate to the parameters currently
being monitored? Is is likely to benefit them financially?
5) Special Condition for Report on Tertiary Treatment - What is our objective with this
information?
6) OCPSF sampling - Given the low detection levels required by tests to show
compliance for the OCPSF parameters, is their any provision for retesting in the event of
a "hit", or is an NOV immediately given.
Outfalls 002 and 003
7) Metals monitoring - What was the basis for monitoring for these parameters? Can the
monitoring requirements be handled outside the permit via a 308 letter?

experts, and Federal departments and agencies.
(b) (1) The Administrator shall, within one hundred
and eighty days after the date of enactment of this title
and from time to time thereafter, publish proposed
regulations establishing pretreatment standards for in-
troduction of pollutants into treatment works (as de-
fined in section 212 of this Act) which arc publicly
owned for those pollutants which arc determined not to
be susceptible to treatment by such treatment works or
which would interfere with the operation of such treat-
ment works. Not later than ninety days after such pub-
lication, and after opportunity for public hearing, the
Administrator shall promulgate such pretreatment stan-
dards. Pretreatment standards under this subsection
shall specify a time for compliance not to exceed three
years from the date of promulgation and shall be estab-
lished to present the discharge of any pollutant through
treatment works (as defined in section 212 of this Act)
which are publicly owned, which pollutant interferes
with, passes through, or otherwise is incompatible with
such works. II', in the case of any toxic pollutant under
subsection (a) of this section introduced by a source into
a publicly owned treatment works, the treatment by
such work, removes all or any part of such toxic pol-
lutant and the discharge from such works does not vio-
late that effluent limitation or standard which would be
applicable to such toxic pollutant if it were discharged
by such source other than through a publicly owned
treatment w orks, and does not prevent sludge use or dis-
posal by such work. in accordance with section 405 of
this Act, then the pretreatment requirements for the
sources actually discharging such toxic pollutant into
such publicly owned treatment works may be revised by
the owner or operator of such works to reflect the re-
mos al of such toxic pollutant by such works."
(2) The Administrator shall, from time to time, as
control technology, processes, operating methods, or
other alternausc change, revise such standards follow-
ing the procedure established by this subsection for
promulgation of such standards.
(3) When proposing or promulgating any pretreat-
ment standard under this section, the .Administrator
shall designate the category or categories of sources to
which such standard shall apply.
(4) Nothing in this subsection shall affect any pre-
treatment requirement established by any State or local

established under this subsection.
(c) In order to insure that any source introducing pol-
lutants into a publicly owned treatment works, which
source would he a new source subject to section 306 if it
were to discharge pollutants, will not cause a violation
of the effluent limitations established for any such treat-
ment works, the Administrator shall promulgate pre-
treatment standards for the category of such sources
simultaneously with the promulgation of standards of
performance tinder sCoion 306 for the equisalcnt cate-
gory of new sources. Such pretreatment standard, shall
prevent the discharge of any pollutant into such treat-
ment works, which pollutant may interfere with, pass
through, or otherwise be incompatible with such s orks.
(d) After the effectisc (late of any effluent standard
or -prohibition or pretreatment standard promulgated
under this section, it shall be unlawful for any owner or
operator of any source to operate ally source in viola-
tion of any such effluent standard or prohibition or pre-
treatment standard.
(c) Compliance Date Extension for Innovative Pre-
treatment Systems. — In the case of any existing facility
that proposes to comply with the pretreatment standards
of subsection (b) of this section by applying an innova-
tive system that meets the requirements of section
301(k) of this Act, the owner or operator of the publicly
owned treatment works receiving the treated effluent
from such facility may extend the date for compliance
with thc applicable prctreatmcnt standard established
under this section for a period not to exceed 2 years—
(1) if thc Administrator determines that thc innova-
tive system has the potential for industrywide applica-
tion, and
(2) if the Administrator (or the State in consultation
with the Administrator, in any case in which the State
has a pretreatment program approved by the Adminis-
trator)—
(A) determines that the proposed extension will not
cause thc publicly owned treatment works to be in
violation of its permit undcr section 402 or of section 405
or to contribute to such a violation, and
(B concurs with the proposed extension.

After twelve months of monitoring data on these metals, the facility may apply to have the data
reassessed for possible discontinuation of monitoring requirements.
Your discharge is located on the Neuse River mainstem which has limited assimilative capacity. Dischargers to the
mainstem of the River must make efforts to treat to advanced tertiary levels, (i.e. 5 mg/I BOD5 and 2 mg/I NH3N).
Therefore, an engineering analysis evaluating the cost feasibility of achieving advanced tertiary treatment levels is due
by February 1, 1997. If advanced tertiary levels cannot be met with state of the art treatment for this industrial type,
then information should be provided detailing the best achievable levels of treatment
Reduced instream monitoring has been included in this NPDES permit under the assumption that the Neuse River
Coalition will be formed and approved by the Division of Environmental Management. It the coalition does not
materialize or you choose not to participate, the NPDES permit may be reopened by administrative letter to include
additional instream monitoring requirements determined to be necessary to adequately characterize the effects of the
discharge on the Neuse River Basin's water quality.

The attached wasteload allocation has been reviewed and the following comments are submitted.
As directed, this information has been discussed with representatives from DuPont - specifically
Jan Kneib of the Kinston Facility and Mike Gell of DuPont's Engineering Office in Charlotte.
Additional metals monitoring has been added to the recommended limits due to ongoing
detections of these parameters. These constituents are not presently used in any process at
DuPont; however, they were found in several biocide products utilized during the 1970's.
Facility may apply to have data reassessed after 12 months of monitoring for possible
discontinuation of monitoring requirement.
Current Cyanide sampling at the facility has repeatedly shown less than detection levels. This
product has not been associated with processes at DuPont. Therefore, this requirement should
be discontinued so as to avoid excessive sampling. -
At this point in time, DuPont is making arrangements to be a part of the Neuse River Coalition.
Their membership in this group will mean reduced instream monitoring already in this NPDES
Permit.
Matrix interference resulting in erroneous results associated with PAH chronic testing concernv
DuPont representatives. Should this test reveal levels above requirements, they propose
additional monitoring along with an agreement with DEM to isolate and remove substance from c om^
process as opposed to a permit violation. A letter outlining their position and reasoning is opporM131r
forthcoming. Further study of such interference is recommended prior to inclusion in permit. (r,,,,,\

Facility Name E. I. Dupont de Nemours and Company Permit # NC0003760 Pipe # 001
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassa:
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant more
is 1.9 % (defined as treatment two in the North Carolina procedure document). The permit holder shall pert
quarterry monitoring using this procedure to establish compliance with the permit condition. The first test NA
performed after thirty days from the effective date of this permit during the months of Jan., Apr., Jul
Oct. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge t
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 perform'
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent to:
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 w
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement v
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 ;
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
survival and appropriate environmental controls, shall constitute an invalid to and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suita a test results will constitute
noncompliance with monitoring requirements.

History
Previous Permit eight (8) years old - facility has adjudicated since then
Previous permit had DO requirement of 2.5 (minimum) tote taken, before chlorine contact chamber. The facility doesn't
actually chlorinate, (some years ago, before the fecal limits and procedures were established, a limit was proposed that
would need chlorination, but this was later dropped). This location is fairly near the plant; the effluent travels through two
more manhole points before reaching the river. The reason that the DO monitoring was established at this point was
accessibility and saftey. The manholes down -pipe are in the floodplain, (thus winter sampling often is impossible) and the
velocities at these points are very high, (thus pulling a sample is very dangerous, and no electricity is available for
automatic sampling at these points). I will continue to keep this sampling as the facility is averaging above five (5) in the
DMR's. The rational for this sampling was that the effluent picks ups around 2 - 2.5 mg/I dissolved oxygen by the time it
reaches the end -of -the -pipe.
The ammonia limit is based on 2.0 mg/I, per Basin Plan, but their BODs is well above the required 5.0 mg/I; this current
permit will allow for 14.1 mg/I BODs.
Overview of meeting 10/24/90
* Requested language in permit which prohibits discharge of organics, [from OCPSF guidelines] and annual monitoring.
Felt that environmental groups would think that these compounds are actually in their effluent. Said Niagara Falls facility
received this.
* Check on state PAH's standards as opposed to OCPSF guidelines.
* Outfalls 002 and 003 have shown metals in their effluent analysis.
"Fact Sheet" outlining previous 'basis' for various effluent requirements in file
Minutes from meeting 1 4/6/931
They need to update their process flows. They have two new lines being scheduled for connection in March 1994
and December 1994. These won't change their design flows as their water usage will be more efficient. These additions
will, however, increase their production, thus their BOD concentrations will be more resilient. This needs to be kept in
mind during the permitting process. DuPont felt that their existing facility can handle the additional loading.
They were interested in how we will be incorporating the metals found in their cooling water discharges [002 &
003] into to their permit. No definite answer was given at this meeting.
Requested information on stormwater constituents.
Their Group Application for a General Stormwater Permit is due in October, (including sampling info.). DuPont
sampled four of their ten outfalls; EPA did not agree w/ their groupings. They will sample one more grouping of 3's to
show that the sites are similar. There are obvious problems w/ the EPA not enunciating any schedules for stormwater
monitoring, etc.
Felt that since their processes haven't changed, existing OCPSF and Priority Pollutant data should be enough.
Obviously we will need to reassess their permit per SOP. The data I have from OCPSF and Priority Pollutant analysis is
from 1989 and 1990. The guidelines require that these constituents be limited, therefore we need to determine whether
monitoring should be quarterly or annual for metals at outfall 003, (they will return supplemental data to us). DuPont
representatives felt that previous hits on chromium and zinc were due their presence in corrosion inhibitors during the
70's. They felt that these metals would no longer be in their effluent, yet the current data we have identifies them.

Toxicity Interaction
A spreadsheet is attached. Outfalls 002 and 003 were included due to their significant findings of toxiciants
present. Neither of these outfalls will be recommended for any limits; the concentrations present would be diluted -out due
to the high 7Q10 at this area. A memorandum will written to the Permits and Engineering section requesting Qrtly
monitoring of these outfalls to verify if these constituents are indeed present, (or were these just annomolous spikes) and
if so at what levels.
Toxicity Test results (per phone call to Larry Ausley).
Permit was held for three years, thus previous recommendation of 1.9% Chronic P / F was never enacted. I have
recommended it.

• Average Clow used for outfa11002. Flow composed of cooling water, condensate, and stormwater, thus maximum flow not appropriate.
•• Maximum flow used for outfall 003. Flow composed of cooling water and condensate.
Contetnea MSD effluent enters this body of water downstream via Contetnea Creek [refer attached map].
Contetnea MSD is allocated to protect the stream segment between its discharge point and the mouth of Contetnea Creek
This concentration of protection Is also more stringent then including Contetnea MSD in a mass balance.

ATTACHMENT II
INFORMATION FOR APPLYING INDUSTRIAL EFFLUENT
LIMITATIONS GUIDELINES TO PERMIT CONDITIONS FOR
E. I. DU PONT KINSTON PLANT
A. Background
The Du Pont Kinston Plant has the following manufacturing operations:
o Manufacture of polyester resin
o Extrusion of the resin for the manufacture of Dacron®
o The melting of polyester fiber from both on and off -site and
re -extrusion into polyester fiber in the SMI operation
All process wastewaters resulting from these three operations, along with sanitary
wastewater and noncontact cooling water (NCCW) are sent to an "end -of -pipe"
activated sludge biological treatment system consisting of aeration and clarification
facilities. The treated effluent is discharged to the Neuse River through Outfall
001.
B. Production in Various Subcategories
The Kinston Plant production described above falls into different subcategories of
the Organic Chemicals and Plastics and Synthetic Fibers (OCPSF) Category
Effluent Limitations Guidelines (40 CFR 414) which the EPA promulgated on
November 5, 1987. The polyester resin manufacture is included in Subpart D
(Thermoplastic Resins), and the polyester fibers manufacture is included in
Subpart C (Other Fibers). Based on the annual production information in
Confidential Attachment III the percent of total production in each of these
categories is as follows:
SUBPART % OF TOTAL PRODUCTION
Thermoplastic Resins 47%
(40 CFR 414 Subpart D)
Other Fibers (SIC 2824) 53%
(40 CFR 414 Subpart C) 100

The OCPSF guidelines provide concentration values which represent Best
Practicable Control Technology (BPT) for the conventional pollutants, BOD5 and
TSS, and Best Available Control Technology (BAT) for 63 priority pollutants.
The concentration values must be multiplied by the appropriate flow values to
determine the daily maximum and daily average permit limits which apply to the
discharge. Table II-1 lists the BPT effluent limitation guideline concentrations for
the subparts which are applicable to production at the Kinston Plant. Table II-2
lists the BAT concentrations for priority pollutants from Subpart I (Direct
Discharge Point Sources That Use End -of -Pipe Biologic Treatment) from OCPSF
Effluent Guidelines.
Several issues are encountered in developing permit conditions in the manner:
o In multi -product plants effluent guideline values must be weighted
according to production in various subcategories.
o Actual discharge flows should be used in the calculation rather than long-
term average flows.
o Appropriate monitoring frequencies should be selected depending on
concern for the presence of levels of pollutants in the discharge.
This Appendix is meant to provide the information necessary for the permit writer
to develop the appropriate guidelines -based permit conditions for Outfall 001, the
wastewater treatment facility effluent, for the Kinston Plant.
C. Effluent Guideline Concentrations
It is recommended that the applicable effluent guideline values for BOD5 and
TSS be determined by deriving a weighted average from Subparts C and D
concentrations using the percent productions associated with each category
as shown above (i.e., 53% for Subpart C and 47% Subpart D). The calculated
results of this weighting procedure are shown in Table II-3 for current and
projected production rates for the Kinston Plant.
D. Flow Basis for Use with Effluent Guideline Concentrations
The concentration -based OCPSF guidelines were developed by EPA by first
determining the long-term average concentrations of regulated constituents in the
wastewaters from its model plant and then applying a variability factor to those
long-term data to reflect the variability in the pollutant concentrations above the
long-term average.

Permit writers are directed to use a "reasonable estimate of process wastewater
flows and the concentration limits to develop mass limitations for the NPDES
permit." (52 Federal Register 42566) In addition, the memorandum NPDES
Permitting Strategy for OCPSF Industry Direct Dischargers (February 28, 1989
from J. R. Elder, EPA OWEP to NPDES Delegated State Directors) the EPA
advises permit writers that "[i]n situations where flow carries significantly from
month -to -month, use discretion to develop a case -by -case determination."
Furthermore in a previous October 12, 1988 memorandum to NPDES State
Directors entitled Questions and Answers Regarding the OCPSF Effluent
Limitations Gudelines, Elder stated that, "[i]t would be within the Permit
Writer's discretion to consider various data in determining a proper long-
term average flow for each facility, e.g., the highest monthly average flow
during the past twelve (12) months or the highest yearly mean of the
twelve monthly average flows during the past five (5) years."
The development of the OCPSF guidelines did not address variability of
flow nor do the concentration guidelines implicitly incorporate flow
variability. There is certainly no direct relationship between constituent
concentration and wastewater flow. An increase in the concentration of a
constituent does not necessarily reflect either an increase decrease in flow.
The most appropriate flows to use in the calculation of mass limits are the
daily maximum flow for daily maximum limits and the maximum monthly
average flow for maximum monthly average limits (called "daily average"
limits in the permit.) The best guidance for such a selection is 40 CFR 122.45
(b) (2) (i), which states the "The time period of the measure of production
shall correspond to the time period of the claculated permit limitations."
That is, for production -based guidelines, EPA directs the monthly average
production that is to be used for monthly average limits and daily maximum
production for daily maximum limits. By analogy, for concentration -based
limits, the monthly and daily flows should be used as described above.
The Schematic of Water Flow in Section I of the Permit Application shows that
the average flow through the treatment facility is approximately 2.5 million
gallons per day (MGD). Most of this flow (about 1.7 MGD) is process waste-
water leaving about 0.1 MGD from sanitary wastewater and about 0.673 MGD
from noncontact cooling water (NCCW) flow. Over a two-year period, 1991 and
1992, the Kinston Plant treated effluent discharge (Outfall 001) recorded a
maximum monthly average flow of 2.7 MGD and a maximum daily flow of 3.2
MGD. These flow increases are largely the result of process wastewater flow
variations and would correspond to a maximum monthly average process
wastewater flow of 1.913 MGD and a maximum daily process flow of 2.413
MGD as shown in Table II-4.

Therefore, we recommend that the maximum monthly average process waste-
water flow of 1.913 MGD be used with OCPSF maximum monthly average
concentrations and that the maximum daily flow of 2.413 MGD be used with
the maximum daily concentrations in Table II-3.
E. Flow and Concentration Basis for Nonprocess Wastewaters
As stated above, a portion of the total wastewater flow through the treatment
facility is nonprocess wastewater. This consists of 0.114 MGD of sanitary
wastewater and 0.673 MGD of noncontact cooling water. These flows are not
expected to vary appreciably.
There are two possible alternatives for considering this additional nonprocess
flow in calculating OCPSF-based limits. One approach would be to combine
these wastewaters with the process wastewater and use the total flow in
conjunction with the OCPSF guideline concentration limits for calculation of
a permit discharge limit. The rationale for this could be that this total flow is
aubject to treatment in the same biological system.
However, this approach is not sanctioned by the OCPSF guidelines which
clearly restrict the application of these guidelines to OCPSF process wastewater.
The other approach would be to apply appropriate treatment levels to the
nonprocess types of wastewater flows based on the recognition that these do
convey BOD5 and TSS into the treatment system and will convey residual
concentrations as a portion of the treated effluent flow. These treatment levels
would be used for the nonprocess wastewater flows to calculate mass discharges
which would be added to the OCPSF process mass discharge allowance to
develop the final permit limit.
We would recommend the application of the second approach with utilization
of secondary treatment requirements (30 mg/1 average and 45 mg/1 maximum
allowances for both BOD5 and TSS) for the sanitary wastewater flow of 0.114
MGD. In addition, we propose that an allowance of 10 mg/1 average and 20
mg/1 maximum for both BOD5 and TSS be used with the noncontact cooling
water flow of 0.673 MGD to account for pollutant loading that will be conveyed
with this flow through the treatment facility.
F. Calculation of Limits
Table II-5 shows the calculation procedure recommended for determing the
OCPSF-based requirements for Outfall 001. The daily average limits for
BOD5 and TSS would be reduced to 416.5 lbs/day (PPD) and 689.3 PPD
respectively since these are lower than the current permit limits.

The daily maximum limits would stay the same, although the OCPSF-based
calculated limits are higher than present permit limits because anti -backsliding
requirements would apply to the permit. Table 1 shows our recommend revise
permit limits for the OCPSF BPT parameters along with other proposed permit
limits.
It should be noted that discharges of five metals and cyanide are regulated by the
OCPSF guidelines. However, EPA diarected that limitations for these pollutants
are to be "determined by multiplying the concentrations listed ... for these
pollutants times the flow from metal -bearing waste streams ..." Note that there
are no specific sources of metals from the production areas at the Kinston Plant.
In addition, use of chromium corrosion inhibitors for cooling water treatment
was ended seven years ago. The discharge data listed in the accompanying
permit application indicate trace quantities of some metals. These low levels
result primarily from the corrosion of tanks, pipes and other equipment. OCPSF
guidelines should not be applied to these metals, unless the entire wastewater
stream is considered the source.
Organic priority pollutants are not handled at the Kinston Plant and we know of
no way that they could be produced in the process operations. Priority pollutant
sampling reported in the permit application have shown nondetectable levels of
all organic polllutants except for bis (2-ethylhexyl) phthalate which is considered
to be a sampling or analytical aritfact since there is no basis for it being present
in the effluent. For these reasons, Du Pont recommends that the priority pollutants
regulated under the OCPSF guidelines be only monitored once annually at
Outfall 001.
