F. This permit shall be modified, or revoked and reissued to incorporate 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.
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 additiona.It m de used in cooling systems. which may

H. The effluent discharge shall at no time exhibit. chronic .toxicity .in.. any .two consecutive
toxicity tests, 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 3.3% (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 issuance of this permit during the months of August, November, February, and May.
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, DEW F6:rrd 'AT-1 (original)'' is"tobe sent to the
following address:

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
Ode
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 reopened and modified to include alternate monitoring requirements ,or limits. .
NOTE: Failure ao achieve test conditions as specified in the cited docWment, 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 monitodig- requirements.
I. The permittee shall conduct a test for pollutants annually at the
plant. The discharge shall be evaluated as follows:
effluent from.,the- treatment
1) A pollutant analysis of the effluent must be completed annually using EPA approved
methods for the following analytic fractions: (a) purgeables (i.e., volatile organic
compounds); (b) acid extractables; (c) base/neutral extractables; (d) organochlorine
pesticides and PCB's (e) herbicidest_and (f) metals and other inorganics. The Annual Pollutant
Analysis :Monitoring (APAM) Requirement Reporting Form A and accompanying:; memo,, to. be
provided to all discharges affected by this monitoring requirement, describes the sampling -and;.
analysis, requirements and lists _chemicals to be included in the pollutant analysis. This_
monitoring requirement is to be referred to. as the "Annual Pollutant Analysis -Monitoring
(APAM) requirement.
2). Other significant levels of;, synthetic organic chemicals must be, identified;: an
approximately quantified. For the . purpose of implementing this requirement, the largest 10
GC/MS peaks in the purgeable, base/neutal extractable, and acid extractable fractions (or
fewer than 10, if less than 10 unidentified peaks occur) for chemicals other than those
specified on the APA Requirement Reporting Form A should be identified and approximately
quantified as stated in the APAM Reporting Form A instructions. This part (item 2) of the APAM
requirement is to be referred to as the "10 significant peaks rule".
DEQ-CFW 00065183

J. The permittee may" submit data -one . year after permit issuapce to the Division of
Environmental Management requesting the Division -to re-evaluate the monitoring frequencies
for certain parameters in this permit.

Dear Mr. Tedder:
(1 ^ .
J; , .
This is in response to your letter of March 16, 1990,
concerning Administrative Orders to cover industries not
meeting deadlines. Specifically, you asked about how to handle
OCPSF facilities. I am attaching a copy of a policy memo you
referred to on this subject. Please note the section on
Compliance Dates on page 4 and 5. Where a discharger cannot
meet the March 31, 1989 statutory deadline, a compliance
schedule must be contained in an administrative order and
public noticed with the permit.
I understand that your special order by consent (SOC) would
serve the same as an administrative order and would also
require public noticing. Inclusion of a compliance schedule in
the OCPSF permit would not be acceptable. If the public notice
for the SOC and the NPDES permit were combined, this approach
should not result in significant delay.
Certainly there are cases where schedules of compliance in
permits are appropriate. However, if a date in the compliance
schedule is in violation of a statutory date it should not be
included in the permit. The use of the administrative order
coupled with a permit containing the statutory deadline.is the
policy for post-1984 deadline enforcement as given in the
legislative history of the 1987 Act.
Sincerely yours,

SECTION D. REPORTING REQUIREMENTS
1. Change in Discharge
All discharges authorized herein shall be consistent with the terms and
conditions of this permit. The discharge of any pollutant identified in
this permit more frequently than or at a level in excess of that authorized
shall constitute a violation of the permit. Any anticipated facility
expansions, production increases, or process modifications which will result
in new, different, or increased discharges of pollutants must be reported by
submission of a new NPDES application or, if such changes will not violate
the effluent limitations specified in this permit, by notice to the DEM of
such changes. Following such notice, the permit may be modified to specify
and limit any pollutants not previously limited.
2.. Antici ated Noncompliance
The permittee shall give notice to the. Permit Issuing Authority of any planned
change in the permitted facility or activity which may result in noncompliance
with permit requirements. Any maintenance of facilities, which might
necessitate unavoidable interruption of operation and degradation of effluent

SECTION E. DEFINITION
1. Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Natural
Resources and Community Development. 3. Elf":
Used herein means the North Carolina Environmental Management Commission.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control. Act, also known as the Clean Water Act, as
amended, 33 USC 1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge: is defined as the total mass of all
daily discharges sampled and/or measured during a calendar month on
which daily discharges are sample and measured, divided by the number
of daily discharges samples and/or measured during such month. It is
therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by
the number of days the tests were reported. The limitation is
identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of
all daily discharges sampled and/or measured during the calendar week
(Sunday -Saturday) on which daily discharges are sampled and measured,
divided by the number of daily discharges samples and/or measured
during such week. It is, therefore, an arithmetic mean. found by
adding the weights of pollutants found each day of the week and then
dividing this sum by the number of days the tests were .reported. This
limitation is identified as "Weekly Average" in Part I of the permit.
C. The "maximum daily discharge" is the total mass (weight) of a
pollutant discharged during a calendar day. If only one sample is
taken during any calendar day the weight of pollutant calculated from
it is the "maximum daily discharge." This limitation is identified as
"Dail.v Maximum," in Part I of the permit.

Part II
Page 12 of 14
d. The "average annual discharge" is defined as the total mass of all daily
discharges sample and/or measured during the calendar year on which daily
discharges are sampled and measured, divided by the number_ of daily
discharges sampled and/or measured during such year. It is, therefore, an
arithmetic mean found by adding the weights of pollutants found each day of
the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the
permit.
Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform
bacteria, is the sum of the concentrations of all daily discharges
samples and/or measured during a calendar month on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled
and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the
arithmetic mean (weighted by flow value) of all the samples collected
during that calendar day. The average monthly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as 'Monthly Average"
under "Other Limits" in Part I of the permit.
b. The "ever_age weekly concentration," other than for fecal coliform bacteria,
is the sum of the concentrations of all daily discharges sampled and/or
measured during a calendar week (Sunday/Saturday) on which daily discharges
are sampled and measured divided by the number of daily discharges sampled
and/or measured during such week (arithmetic mean of the daily
concentration values). The daily concentration value is equal. to the
concentration of a composite sample or in the case of grab samples is the
arithmetic mean (weighted by flow value) of all the samples collected during
that calendar day. The average weekly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar
week. This limitation is identified as "Weekly Average" under "Other
Limits" in Part I of the permit.
C. The "maximum daily concentration" is the concentration of a pollutant
discharge during a calendar day. If only one sample is taken during any
calendar day the concentration of pollutant calculated from it is the
"Maximum Daily Concentration". It is identified as "Daily Maximum" under
"Other Limits" in Part I of the permit.
DEQ-CFW 00065206

Part II
Page 13 of 14
d. The "average annual concentration," other than for fecal coliform bacteria,
is the sum of the concentrations of all daily discharges sampled and/or
measured during a calendar year on which daily discharges are sampled and
measured divided by the number of daily discharges sampled and/or measured
during such year (arithmetic mean of the daily concentration values). The
daily concentration value is equal to the concentration of a composite
sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The
average yearly count for fecal coliform bacteria is the geometric mean
of the counts for samples collected during a calendar year. This
limitation is identified as "Annual Average" under "Other Limits" in Part I
of the permit.
e. The "daily minimum concentration" (for dissolved oxygen only) is the
minimum allowable amount of dissolved oxygen required to be available in
the effluent prior to discharge. It is identified as "Daily Minimum" under
"Other Limits" in Part III of the permit.
7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours
average flow, averaged monthly. It is determined as the arithmetic mean
of the total daily flows recorded during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time
of sampling, when both the sample and flow will be representative of the
total discharge.
R. Types of Samples
a. Composite Sample: These samples consist of grab samples collected at
equal intervals and combined proportional to flow, a sample continuously
collected proportionally to flow, or equal volumes taken at varying time
intervals. If a composite sample is obtained from grab samples, the
following requirements apply. The intervals between influent grab
samples shall be no greater than hourly. Intervals between effluent grab
samples shall be no greater than hourly except where the detention time
of the wastewater in the facility is greater than 24 hours, in which
case, the interval between grab samples shall be no greater in number of
hours than the detention time in number of days; provided, however, in
no case may the time between effluent grab samples be greater than six
hours nor the number of grab samples less than four during any discharge
period of 24 hours or less.
b. Grab Sample: Grab samples are individual samples collected over a
period of time not exceeding 15 minutes; the grab sample can be taken
manually.
DEQ-CFW 00065207

Part II
Page 14 of 14
9. Calculation of Means
a. Arithmetic Mean: The arithmetic mean of any set of values is the summation
of the individual values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of
the product of the individual values where N is equal to the number of
individual values. The geometric mean is equivalent to the antilog of
the arithmetic mean of the logarithms of the individual values. For
purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).
C. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the
respective flows.
lendar Dav
A calendar day is defined as the period -from midnight of one day until midnight
of the next day. However, for purposes of this permit, any consecutive 24-hour
period that reasonably represents the calendar day may be used for sampling.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of
the Clean Water Act.

Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be reopened 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.
I. The permittee shall conduct a test for pollutants annually at the effluent from the treatment
plant. The discharge shall be evaluated as follows:
1) A pollutant analysis of the effluent must be completed annually using EPA approved
methods for the following analytic fractions: (a) purgeables (i.e., volatile organic
compounds); (b) acid extractables; (c) base/neutral extractables; (d) organochlorine
pesticides and PCB's (e) herbicides; and (f) metals and other inorganics. The Annual Pollutant
Analysis Monitoring (APAM) Requirement Reporting Form A and accompanying memo, to be
provided to all discharges affected by this monitoring requirement, describes the sampling and
analysis requirements and lists chemicals to be included in the pollutant analysis. This
monitoring requirement is to be referred to as the "Annual Pollutant Analysis Monitoring"
(APAM) requirement.
2) Other significant levels of synthetic organic chemicals must be identified and
approximately quantified. For the purpose of implementing this requirement, the largest 10
GC/MS peaks in the purgeable, base/neutal extractable, and acid extractable fractions (or
fewer than 10, if less than 10 unidentified peaks occur) for chemicals other than those
specified on the APA Requirement Reporting Form A should be identified and approximately
quantified as stated in the APAM Reporting Form A instructions. This part (item 2) of the APAM
requirement is to be referred to as the "10 significant peaks rule".

SAVE AND COMPLY WITH SLUDGE DRYER
DURCO'S NEW ENVIRO-DRIT" DURCO
■ Waste Minimization
■ Decreased Liability
■ Payback Less Than 24
Months
■ Disposal Cost Savings As
High As 75%
The Durco ENVIRO-DRI' steam
sludge dryer has been engineered with
one purpose in mints:
To slash your metal hydroxide disposal
costs while addressing current environ-
mental guidelines.
Its very design saves you money.
This low cost unit uses steam heat to
reduce sludge volumes 50 to 75%.
That makes ENVIRO-DRI'" the most
energy efficient, cost effective dryer
available. It also means simple and
easy installation with minimal mainte-
nance for further savings.
The use of inexpensive steam as its
primary heat source not only maximizes
efficiency, it reduces drying time. Typical
drying cycles average 4 hours or less
allowing 2 cycles per work shift. The
heavy duty auger assures complete
and continuous exposure of sludge to
the heat transfer surfaces of the
jacketed hopper for maximum dryness.
Volume and weight reductions of
sludge to 75 % directly translate into
significant hauling and landfill disposal
cost savings. Just as important, waste
minimization decreases liability while
helping you address EPA and RCRA
guidelines. Within 12 to 24 months
ENVIRO-DRI" will have paid for itself.
(Please see the back page of this
brochure to calculate the projected
savings and payback period when
using ENVIRO-DRI'".)
ENVIRO-DRI'" is available in
capacities from 2 cubic feet to 36 cubic
feet. Its rugged all welded construction
features automatic shutoff with manual
override, highly efficient motor and
oversized gear reducer, controls, piping
and connections. Since it uses steam,
there is no open flame or electric heat-
ing elements so fire and explosion
hazards are virtually eliminated.
Field demonstrations, testing ser-
vices and the "5110" financing plan are
all available to help you choose the
ENVIRO-DRI'" that is best for your
sludge dewatering needs.

Impinjet is actually two
scrubbers in one. The spray
section cools and humidifies
entering gas while simultaneously
removing larger particulate
matter. In addition, the under -
plate spray action keeps the plate
and walls clean and prevents
build-up.
Actual scrubbing is accomplished
by the jet action of
gas in the liquid,
produced by the
uniquely designed
impingement baffle
plate. This turbulent
effect assures
thorough wetting of
particles. Impinge-
ment baffle plates are
generally made of
high efficiency found in our impingement plate
design:
1. the formation of a great number of
minute droplets of liquid at plate orifices,
and
2. the high velocity, relative to the minute
droplets, at which dust particles enter the
orifices. [Few scrubbers have both high
relative velocities and form minute
droplets which in combination
give the highest efficiency
possible at any given pressure
drop.)
Greater particle collection
efficiency is attainable by
increasing relative velocity
(higher pressure drop). The net
effect is an improvement in the
relative velocity of dust and
liquid droplets, intensifying the

MEMORANDUM
TO: Don Safrit, Supervisor
Permits & Engineerin
FROM: M. J. Noland, Regional-Supery r
Fayetteville Regional Office
SUBJECT: NPDES Permit No. NCOOD3573
AC0003573
Authorization to Construct
E. I. du Pont de Nemours & Company
Fayetteville Plant
Bladen County
The subject Authorization is being requested so that Biopond sludge can
be properly prepared for shipment at an approved landfill site in Pinewood,
South Carolina.
The proposed facility consists of the following:
Thickening:
Excess waste sludge is taken from the waste treatment clarifiers recycle
stream and fed to a Dissolved Air Floatation Thickener (DAF), where the solids
are concentrated to a nominal 3% from 0.5%. The DAF effluent is pumped to the
Digester, where it is held until it is pumped to sludge dewatering. The
Digester is an existing concrete lined basin that was previously used as the
biological treatment aeration basin prior to 1989.
Dewatering:
The thickened sludge is mixed with a commercial coagulant aid, and is
then pumped to a Pre -Thickener, followed by a Screw Press where the solids are
concentrated to a nominal 8%. The dewatering system filtrate is returned to
the waste treatment equalization tank.
A standard belt conveyor is used to transport the dewatered sludge to an
intermediate 2,200-gallon sludge holdup vessel and then conveyed to the drying
system.
DEQ-CFW 00065219

Mr. Don Safrit
Page 2
December 4, 1989
Drying:
Sludge drying is accomplished by using a steam heated dryer to boil off
about 70% of the water in the waste sludge. A blower is used to pull water
vapor from the dryer to the direct water spray type scrubber. The scrubber
collected water effluent is returned to the waste treatment equalization tank.
The dry sludge, nominal 26% solids, is conveyed to the landfill con-
tainer.
0 Landfill:
When a landfill container is full, about 22,000 lbs., it is then shipped
to the approved landfill, which is currently the GSX landfill in Pinewood,
South Carolina.
The proposed facility will consist of three major commercially available
sludge handling units connected in a series. This sequential treatment will
generate a suitably landfillable sludge. The equipment will be centrally
housed in one building and all filtrates and water streams discharge back to
the headwaters of the company's wastewater treatment plant. The proposed
sludge handling facility will not affect existing outfalls and no changes are
requested for discharge -parameters.
It is the recommendation of this office that the Authorization to
Construct for the proposed sludge handling facilities be processed and the
appropriate Authorization issued.

Wide Choice of Tank Designs
The many advantages of Rex H'loat-Treat Separators may be
obtained with either steel or concrete tanks, In single or multiple
units. Steel tanks are available as "packaged duty' units shipped
complete, ready for simple piping and wiring on installation.
Existing gravity settling tanks cart often be converted eco-
nomically to Float -Treat Existing sludge -handling equipment
may also be used with slight modifications.

SAVE AND COMPLY WITH SLUDGE DRYER
DURCO'S NEW ENVIRO-DRIT" =DURCO
■ Waste Minimization
■ Decreased Liability
■ Payback Less Than 24
Months
■ Disposal Cost Savings As
High As 75%
The Durco ENVIRO-DRI'" steam
sludge dryer has been engineered with
one purpose in mind:
To slash your metal hydroxide disposal
costs while addressing current environ-
mental guidelines.
Its very design saves you money.
This low cost unit uses steam heat to
reduce sludge volumes 50 to 75%.
That makes ENVIRO-DRI" the most
energy efficient, cost effective dryer
available. It also means simple and
easy installation with minimal mainte-
nance for further savings.
The use of inexpensive steam as its
primary heat source not only maximizes
efficiency, it reduces drying time. Typical
drying cycles average 4 hours or less
allowing 2 cycles per work shift. The
heavy duty auger assures complete
and continuous exposure of sludge to
the heat transfer surfaces of the
jacketed hopper for maximum dryness.
Volume and weight reductions of
sludge to 75 % directly translate into
significant hauling and landfill disposal
cost savings. Just as important, waste
minimization decreases liability while
helping you address EPA and RCRA
guidelines. Within 12 to 24 months
ENVIRO-DRI" will have paid for itself.
(Please see the back page of this
brochure to calculate the projected
savings and payback period when
using ENVIRO-DRI"'.)
ENVIRO-DRI'" is available in
capacities from 2 cubic feet to 36 cubic
feet. Its rugged all welded construction
features automatic shutoff with manual
override, highly efficient motor and
oversized gear reducer, controls, piping
and connections. Since it uses steam,
there is no open flame or electric heat-
ing elements so fire and explosion
hazards are virtually eliminated.
Field demonstrations, testing ser-
vices and the "5/10" financing plan are
all available to help you choose the
ENVIRO-DRI'" that is best for your
sludge dewatering needs.
