Dear Mr. Patel:

Subject: NPDES Permit Issuance
Permit No. NC0003719
Monsanto Company
Cumberland County
In accordance with the application for a discharge permit received on March 15, 1995 the
Division is forwarding herewith the subject 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 U.S. Environmental Protection Agency dated December 6, 1983.
In response to the comments submitted by Monsanto on December 7, 1995, the following
responses are provided.
1. Part I.A.5. and Part I.A.6: The monthly average and daily maximum tables provided in the
comment letter and in this final permit are correct.
2. Part I.A.7 and Part I.A.8: The duplicate compounds listed have been removed and the
cumulative allocations are now listed for the appropriate single entry.
Since both Monsanto and ICI are currently in expansion start-up with completion scheduled for the
first of the year, Part I.A.7. has been deleted as requested.
3. Part II, Section A.1.b.(2): The secondary containment requirements are intended to apply
to bulk storage of liquid materials that have the potential to contaminate stormwater runoff. As
such, the routing of surface water from these areas to the wastewater treatment plant supersedes the
need for secondary containment of structures within these drainage areas.
4. Part II, Section A.3.(b): This section has been changed to read, "...qualitative visual
inspection of each stormwater outfall discharging runoff from production and material handling
and storage areas..." Footnote 3 has been added as requested.
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,

PART I
WASTEWATER MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: FINAL LIMITATIONS AND CONTROLS FOR WASTEWATER DISCHARGES
1. Biocide Approval
The permittee is not required to notify the Division of changes in biocide use where said biocides
are specifically treated and discharged through the wastewater treatment plant. The permittee shall
notify the Director in writing not later than ninety (90) days prior to instituting use of any biocide
used in the cooling systems which is not discharged through the wastewater treatment plant and
which May be toxic to aquatic life.
2. Detection Levels for Compliance
If the discharge limitation of a given parameter is below detection limits, the measured quantity for
the purposes of a compliance evaluation is considered to be zero. Values which report below
detection level shall be deemed to be in compliance.
3. Acute Toxicity Pass/Fail Permit Limit (Quarterly)
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute
Toxicity In A Single Effluent Concentration." The monitoring shall be performed as a Fathead
Minnow (Pimephales promelas) 24 hour static test, using effluent collected as a 24 hour
composite. The effluent concentration at which there may be at no time significant acute mortality
is 90% (defined as treatment two in the North Carolina procedure document). Effluent samples for
self -monitoring purposes must be obtained during representative effluent discharge at the combined
outfall box located below outfalls 001 and 002. The first test will be performed after thirty days
from the effective date of this permit during the months of February, May, August, November.
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 TGE6C. Additionally, DEM Form AT-2 (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

Part I Permit No. NC0003719
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 either these monitoring requirements 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.
4. OCPSF and Pesticide Scans
The perinittee is required to perform quarterly full range OCPSF pollutant and pesticide scans after
start-up of the currently planned ICI expansion. These scans shall include all parameters listed as
effluent limitations and monitoring requirements for outfall 002 in Part I.A.7 of this permit. The
results of OCPSF and pesticide monitoring shall be submitted to the Division within 30 days of
receipt of the analytical results final report. This permit shall be modified, or revoked and reissued
to incorporate additional OCPSF and pesticide limitations and monitoring requirements in the event
the OCPSF and pesticide pollutant scan indicates that increased monitoring frequencies for all or
part of the pollutant list are necessary. After eight monitoring events, the permittee may petition the
Division to modify requirements for parameters not found to be of significant concern.

map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharg;.:s to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the point(s) of discharge.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and
activities occurring in the drainage area, building locations and impervious surfaces,
and the percentage of each drainage area that is impervious. For each outfall, a
narrative description of the potential pollutants which could be expected to be
present in the stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility

b . For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See definitions in
Part III, Standard Conditions). Failure to monitor representative storm events in
accordance with the specified frequency shall constitute a violation of this permit. If the
stormwater runoff is controlled by a detention pond, the following sampling requirements
shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required, but analytical sampling shall not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part III, Standard Conditions, Section A), the pond shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
c. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
provided by the Director no later than January 31 for the previous year in which sampling
was required to be performed.
d. Analytical results from sampling during the final year of the permit term shall be submitted

For each parameter, the arithmetic mean of all analytical sampling results collected during the term of the permit shall be calculated for each
individual outfall and compared to the cut-off concentrations listed. If the arithmetic mean meets the specified cut-off concentration
condition for a given parameter, then th,; facility is not required to continue annual analytical monitoring for that parameter at that outfall
during the term of the permit except for the last year of the permit term as stated below unless a significant change in facility operations or
configuration occurs. If a cut-off con::.entration results in discontinued analytical monitoring at an individual discharge outfall, the
permittee is required to maintain facility operations that ensure the continuation of stormwater runoff quality.
The permittee must perform analytical sampling during the first and last year of the permit term regardless of cut-off concentration
conditions. Analytical results from sampling during the final year of the permit term must be submitted with the permit renewal
application.

area, and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute intervals during the rainfall event.
For purposes of the stormwater sampling required in this permit, all samples shall be collected from a discharge resulting from a
representative storm event (See Part III.A.16). Failure to monitor storm events in accordance with the specified frequency shall constitute a
violation of this permit.
(b) Visual Monitoring
Visual monitoring requires a qualitative visual inspection of each stormwater outfall discharging runoff from production and material
handling and storage areas, regardless of representative outfall status, for the purpose of evaluating the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests are required. Visual monitoring
of stormwater outfalls does not need to be performed during a representative storm event.

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

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 sampled 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.

The
pesticides guidelines as well as the OCPSF guidelines allow us to
discharge up to 346 lbs.%day. However, we are being regulated well below
that at the proposed 200 lbs,%day for 4 out of the 5 years of permit duration.
> While Monsanto's present and past treatment system has continued to
perform at an "impressive" efficiency in SOD removal we are, with the
proposed expansion, embarking upon "new grounds" that will require
additional time and costs to maintain close to similar treatment standards.

DIVISION OF ENVIRONMENTAL MANAGEMENT
WATER QUALITY SECTION
NPDES GROUP
March 20,1995
MEMORANDUM
To: Steve Tedder
Water Quality Section Chief
Through: Don Sa
Technical Support Branch Assistant Chief
Coleen Sullins
Permits and Engineering Unit Supervisor
From: Dave Goodrich\
NPDES Group upervisor
Subject: Proposed Limits for Monsanto WWTP Expansion
NPDES Permit #NC0003719
Cumberland County
After reviewing the preliminary information provided by TRC Enivronmental Corporation
(Monsanto's consultant) and discussing permitting issues with you and Water Quality Section staff, I
would offer the following comments regarding the development of limits for this facility.
There are three general methods of developing limits for permits:
1) Base limits on model results.
2) Base limits on BPJ.
3) Base limits on BAT.
The existing permit limit of 350 lbs/day for BOD5 (summertime limit) was derived through a
combination of #1 and #3, although it was primarily the BAT limits which were suggested by
Monsanto.
EXISTING WATER QUALITY. CONCERNS
Ambient monitoring data are collected by the Division in the mainstem of the Cape Fear River on a
monthly basis. These data indicate that dissolved oxygen levels are depressed in the area of
Monsanto's discharge to levels below 6 mg/1 under summertime conditions. Instream BOD5
concentrations are also much higher in the Cape Fear River mainstem when compared to nearby
rivers like the Black and South Rivers which do not have significant point source impacts. It should
be noted that the ambient data reflect existing loading from point and non -point sources as opposed to
permitted loading to this system.
Facility instream data are also collected which show levels of DO below the standard on the
mainstem of the river (see attachment). It is possible that these data don't corroborate the

information collected by the Division as a result of differences in the time of day in which samples
are collected and/or the effect of algal activity upstream of the lock and dams.
QUAL2E MODEL RESULTS
Although model results are not finalized, Monsanto discharges to the beginning of a DO sag which is
predicted to depress levels of oxygen below the standard (see attachment). Monsanto is one of many
discharges which contributes to this sag. The significance of this finding is that existing permitted
loading is not predicted to protect the dissolved oxygen levels in the Cape Fear River basin.
BPJ CONSIDERATIONS
Over the past few years, the Division has been assigning limits no less stringent than 12 mg/1
(summertime BOD5) and 2 mg/1(summertime NH3) to all expanding domestic facilities
upstream of Lock and Dam #1 on the Cape Fear River. Although these limits were derived
from preliminary modeling evaluations, the 12 and 2 limits are considered "BPJ" since they
have been applied to virtually every expanding discharger without regard to total loading to
the system. It was the concensus of Water Quality Section staff that these limits are
appropriately applied to municipal and domestic wastewater discharges only.
Another consideration was to examine what the Division was requiring other similar
industrial discharges to meet in this area. DuPont is anOCPSF discharger in the proximity of
the Monsanto discharge with a flow limit of 2 MGD and a BOD5 summertime limit of 175
lbs/day <equivalent allowable concentration of 10.5 mg/1 at design flow). After reviewing
information about the specific operation of this plant and type of wastestream being treated, it
was decided by staff not to recommend equivalent loading be given to Monsanto based purely on
this type of "BPJ".
DETERMINATION OF BAT
The simplest way to predict mass limits based on BAT would be to calculate average
concentrations of BOD5 which are currently being discharged and extrapolate this
concentration to the requested permitted flow limit. Based on the data provided by Monsanto,
the average concentration of BOD5 in the effluent is 5.8 mg/1 (summer) and 10.3 (winter -
excluding March 1994). This would equate to mass effluent limits of 63 lbs/day (summer) and
112 lbs/day (winter). However, is this an appropriate method.to use when determining a BAT
limit? In this case, it is probably not. Since production and wastewater flow are not increasing
proportionately, Monsanto will most likely experience an increase concentration of influent
BOD5. The idea of averaging effluent concentrations also does not provide for operational
variations at the facility. Therefore, in order to calculate limits based on BAT, two factors
were determined:
• Removal efficiency of treatment system
• Relationship between production and resultant :predicted influent BOD5 loading
The assumption of a removal efficiency of the treatment system is an important element in
determining what type of treatment is reasonably achieved at a. given WWTP. Although a
difference of one or two percentage points would appear to be inconsequential, this is not the
case. For example, in considering a BPJ limit of 120 lbs/day, removal efficiencies of 98% and
99% were assumed in order to calculate the mass of influent BOD5 which could be treated by
the WWTP. The results were:

Effluent Limit % Removal Assumed Max. Influent Mass which
could be accepted by the
WWTP
120 lbs/day
120 lbs/day
98%
99%
6000 lbs/day
12000 lbs/day
This determination, then, is extremely important, and was a focus of the analysis to recommend
BAT limits. Based on information supplied by the company, the removal efficiencies for
Monsanto's WWTP are listed in the following table:
Date Observed Removal Efficiency
Apr 1993 99.6%
May 1993 99.7%
Jun 1993 99.8%
Ju11993 99.8%
Aug 1993 99.8%
Sep 1993 99.6%
Oct 1993 99.7%
Nov 1993 99.7%
Dec 1993 99.6%
Jan 1994 99.3%
Feb 1994 99.0%
Mar 1994 89.9%
Apr 1994 99.4%
May 1994 99.4%
This period of time was presented to the Division by Monsanto as representing a typical
production period and was also assumed to represent the range of treatment capability. Also,
note that the March 1994 removal efficiency was a result of a major plant upset which was
corrected by the company and not represented in the data collected during the following month.
It was not considered a representative removal efficiency in this analysis. Monsanto has
committed to increasing treatment of BOD5 at their Fayetteville facility and should be able to
do so with the proposed changes to the wastewater treatment system (see attachments).
Summertime removal efficiencies range from 99.4 - 99.8%. However, again realizing the
potential for operational variation, a removal efficiency of 99% was assumed in this analysis.
This matches the lowest removal efficiency documented in the representative months above
and is also quoted as the removal efficiency in all four of the treatment methods performed
during the company's treatability study.
Since ICI and Wellman are both OCPSF facilities, allowable BOD5 limits are determined
using the Federal Guidelines (40 CFR 414). Based on predicted wasteflow and the highest
monthly average flow observed during the representative time period, 52.8 lbs/day should be
allowed for these wastestreams. Measured influent values for Monsanto were increased by a
ratio of lbs/day of BOD5 to lbs/day of product produced multiplied by the maximum predicted
production rate in a single month. The resulting influent values ranged from 5664 lbs/day to
14733 lbs/day. Assuming the highestpredicted monthly mass (14733 lbs/day) and a 99%
removal efficiency, the BAT limit for Monsanto's contribution to the treatinent system would be
147.3 lbs/day. Therefore, when added to the allowance from the OCPSF facilities (52.8
lbs/day), the Division should require Monsanto to meet a limit of 200 lbs/day.
These values were checked by ignoring the OCPSF requirements and increasing the influent
loading from ICI by 30%. Effluent values from the resulting worst -case month-(i.e., BAT limit)
was 208 lbs/day which is comparable to the 200 lbs/day limit recommended.

MONSANTO: EXISTING TREATMENT WORKS
The existing Monsanto treatment system consists of a spill basin .(1 MG - seldom used), an equalization
basin (4 MG), oil/water separator, pH adjustment, two aeration basins (0.4 MG, 1 MG), two clarifiers
(90 ft - in use, 50 ft - not in use), sandfilters (not in use), chlorine contact chamber (not in use), an aerobic
sludge digestor, a sludge storage basin and sludge drying beds. Additionally, Monsanto has side -stream
treatment systems for some of their more highly concentrated waste stream (centrifuge spent wash
wastewater) that are not in use, including two sequencing batch reactors and an incinerator. Currently,
waste streams from different production areas and sanitary contribution are brought into the treatment
system at different points. For example, the centrifuge spent wash is added to the treatment system
after the equalization basin and the sanitary contribution is added at the second aeration basin
MONSANTO RECONFIGURATION:
Monsanto is proposing to re -pipe the existing influent waste streams to the head of the wastewater
treatment plant and modify the existing in -ground components to obtain better levels of treatment. The
reconfiguration of the system still does not propose to use all of the treatment components that are on -
site, specifically, the sequencing batch reactors, the 50 ft clarifier, the sandfilters, the chlorine contact
basin and the incinerator are not proposed to be used. Additionally, the function of the existing
remaining units will -be modified:
Oil/water separator (same function, propose to modify slightly)
Spill Basin - converted to equalization basin (1 MG - permitted flow requested is 1.3 MGD,
therefore, size as an equalization basin is more than sufficient)
Equalization basin - converted to primary aeration basin-(4 MG capacity)
eration basin - proposing to convert one of the existing two aeration basins into a sludge digestor,
the initial proposal is to convert the larger (1 MG) to a sludge digestor and use the smaller
aeration basin (0.4 MG) in series with the new primary aeration basin (4 MG). Proposal
also includes piping to bypass the secondary aeration basin and potentially not use it in the
treatment scheme.
Clarifiers - continue to use the 90 ft diameter clarifier, not proposing to use the smaller clarifier.
This reconfiguration will consist of relocating the pH adjustment to the lift station at the head of the
treatment plant, adding four 7.5 HP mixers to the new equalization basin, relocating existing aerators to
the new equalization basin and adding six additional aerators to the primary aeration basin.
TREATMENT DESIGN CONSIDERATIONS
A comparison of theexistingdesign parameters to the reconfigured system supports the determination
that the system will provide equal or slightly better levels of treatment. The current system is
providing a detention time of 74 hours in the aeration system, producing average effluent concentrations
of 8 mg/1 BOD5 and 1 mg/1 NH3. Under the expansion and reconfiguration the aeration detention time
will be 80 hours. The 90 ft. clarifier is also adequately sized to handle the loading rate that is
projected to occur. Therefore, it appears that the system will provide similar levels of BOD5/Ni-i3
removal as those currently being achieved. Proposed permit limits (GODS = 200 #/day, or —18 mg/1)
should provide an adequate window for compliance.

insufficient levels of oxygen in stage 1.
■ Both the waste bypassing stage I and the partially treated waste exiting stage I
join together just downstream of stage 1 before entering stage 11.
■ At this point the waste are again split to give a 30/70 loading to second stage

One hundred and seventy-two acres under permit.
▪ Consists of both grass (pasture) land and set aside land.
® Solids can be applied without incorporating on grass.
® All land application plots are supplied with monitoring wells before
applying any solids to them as mandated by Monsanto Corporate
procedures.

Dear Ms. Sullins:
As a follow-up to our telephone conversations on 3/21/95, Monsanto personnel have
had an opportunity to review your preliminary proposal to limit the BOD discharge level
which we understand to be as follows.

Having evaluated the above limitations and timing factors involved in meeting the
above criteria, the following comments are offered for your information and further
consideration.
> The pesticides guidelines as well as the OCPSF guidelines allow us to
discharge up to 346 lbs. f day. However, we are being regulated well below
that at the proposed 200 lbs./day for 4 out of the 5 years of permit duration.
While Monsanto's present and past treatment system has continued to
perform at an "impressive" efficiency in. BOD removal we are, with the
proposed expansion, embarking upon "new grounds" that will require
additional time and costs to maintain close to similar treatment standards.

> The lab scale bio-Rx studies were done to provide indicators to operating
windows and not to determine performance from bench to field. It is evident
that simple linear extrapolation of controlled bench scale performance to field
cannot be assumed, nor expected, due to variabilities.
> The goal of the bio-Rx studies, therefore, provided critical information such
as Oz requirement, net solids generation, and the impact of hydraulic
residence times (I-IRPs).
• The 02 demand for the stage 1 aeration under the proposed configuration and
loadings indicated 40 mg/liter/hr. or 1.98 lbs. 02/lb. BOD in the influent.
> As mentioned and shared with you earlier, Monsanto has already designed
into this expansion a reduction in the proportionate amount of waste
generation utilizing internalized techniques of stream recycling to a rate of
greater than 30% less waste per pound of product (less load to the bio-system
per unit of production).
• Also shared with you previously was a description of discharge allocation of
BOD per unit of Monsanto production. As summarized in the table below,
significant reductions in discharge allocations are indicated.

proposes and sincerely expects that you will consider the following approach to meeting our

The above proposal is considered by Monsanto to be challenging but reasonable, since it
allows The necessary time to address the waste treatment technology, while allowing the
start-up factors involving both ICIA's and Monsanto's projects to be fully integrated into the
current system.
The gradual reduction approach to BOD discharge limits over the subsequent period
additionally assists Monsanto to channel appropriate technological resources in defining and
implementing the bio-treatment schemes.
We trust that you will consider this request to be reasonable and allow us to proceed
along these lines. Please note that, should we be able to reach our target limits ahead of
the stated timing, Monsanto will not hold back resources to implement actions to fulfill that
goal ahead of schedule.

OCPSF Parameters: The existing permit requires Monsanto to monitor quarterly for
Methylene Chloride, Phenol, Bis(2-ethylhexyl)phthalate, Chloroform, 2-Chlorophenol,
Chromium, Copper, Cyanide, Lead, Nickel, Zinc, and Total PAH's and monitor annually
for all remaining OCPSF parameters as listed in 40 C I R 414, Subpart I. The parameters
monitored quarterly were detected in an earlier battery of effluent sampling done by
Monsanto. ICI, Inc. is undergoing a major increase in production along with a
significant change in production methods. The monitoring frequency should be raised
again for all parameters at least until sufficient data for a toxicant analysis is obtained.
The data should be collected at a frequency no more than monthly and no less than
quarterly during a period in which all production expansions (Monsanto and ICI) are
: complete and all planned treatment components are operational until at least 12 data
points have been accumulated. It should be communicated to the permittee that, once the
necesAary data are obtained, a permit modification may be requested, and upon analysis of
the data, monitoring may be reduced to an annual frequency again for the appropriate
parameters. Monsanto will likely do sampling for OCPSF parameters over and above
permit requirements on various influent and treatment system waste streams. The permit
cover letter should contain a request that the permittee provide the results of any
additional sampling to DEM for our evaluation.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
This WLA recommends a reduction of BOD5 from 350 lbs/day to 200 lbs/day, because modeling
analysis of Cape Fear mainstem (with field calibrated QUAL2E) has indicated that cumulative
loading of oxygen demanding wastes from point sources is a significant factor contributing to low
dissolved oxygen levels in the lower half of the river. The Cape Fear Basin Plan recommends
tertiary limits for all new and expanding major domestic discharges and BAT limits for major
industries to be evaluated on a case by case basis. Analysis (by P&E) of removal efficiencies for
Monsanto's treatment system has shown it to be consistently capable of achieving 99% removal of
BOD5, which will allow the facility to meet the lower limit. NBOD loading is not a significant
factor in this discharge so NH3N limit should remain unchanged. Monitoring frequency for
OCPSF parameters has increased due to production increase with process change at ICI, Inc.
Design flow increase for Monsanto will increase IWC slightly, but not enough to change toxicity
test requirement.

It should be noted that Monsanto's instream data is somewhat su ect, becausa Fayetteville PWC
takes downstream samples for the Rockfish Creek at the exact same si and when
samples are taken on the same days and near the same time, Monsanto's reported DO levels are
consistently 1-2 mg/1 higher than PWC's.

Special Instructions or Conditions
OCPSF Limits and Monitoring:
The existing permit requires Monsanto to monitor quarterly for Methylene Chloride, Phenol,
Bis(2-ethylhexyl)phthalate, Chloroform, 2-Chlorophenol, Chromium, Copper, Cyanide, Lead,
Nickel, Zinc, and Total PAH's and monitor annually for all remaining OCPSF parameters as listed
in 40 CFR 414, Subpart I. The parameters monitored quarterly were detected in the effluent in an
earlier battery of sampling done by Monsanto. Since ICI, Inc. is undergoing a major increase in
production along with a significant change in production methods, the monitoring frequency f s
v
should be raised to quarterly for all parameters until sufficient data for a toxicant analysis is �.� ��`�
obtained (12 or more data points). It should be communicated to the permittee that, once the
necessary data are obtained, monitoring will be reduced to an annual frequency again for the
appropriate parameters. Monsanto will likely do sampling for OCPSF parameters over and above
permit requirements on various influent and treatment system waste streams. The permit cover
letter should contain a request that the permittee provide the results of any additional sampling to
DEM for our evaluation.
Wasteload sent to EPA? (Major) Y (Y or N)
(If yes, then attach updated evaluation of facility, including toxics analysis, modeling analysis if
modeled at renewal, and description of how it fits into basinwide plan)
Additional Information attached? Y (Y or N) If yes, explain with attachments.

ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent
Concentration." The monitoring shall be performed as a Fathead Minnow (pimephalea promelas) 24 hour static
test, using effluent collected as a 24 hour composite. The effluent concentration at which there may be at no time
significant acute mortality is 90% (defined as treatment two in the North Carolina procedure document). Effluent
samples for self -monitoring purposes must be obtained during representative effluent discharge below all waste
treatment. The first test will be pert ed after thirty days from the effective date of this permit during the
months of f A/1a
y�
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 TGE6C.
Additionally, DEM Form AT-2 (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 either these monitoring requirements 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.

species. A Poor bioclassification was assigned to Little Rockfish Creek and the data indicate
that the Stevecoknit facility is stressing benthic fauna and is a possible contributor to the
degraded water quality of Rockfish Creek below Wallace.
The writer observed discolored water on the Northeast Cape Fear River near SR 1318
on June 5 and complaints were received by this office on June 6 and 8 regarding colored waters
in this same area. One of the complaintants said he had caught fish which had leisons. SR 1318
is located roughly 14 miles downstream from the Stevecoknit discharge point. Colored waters
were also apparent at the writers house, located roughly 19 miles downstream. Discolored
waters have been observed in Rockfish Creek at I-40 on several occassions, but were fairly
constant during May and June of this year due to dry weather conditions, and consequently low
flows in the creeks. A color sample collected at I-40 on May 3 measured 390 (ADMI at pH
7.8). A sample collected the same day from Little Rockfish Creek at NC 11 measured 1100
(ADMI at pH 7.6). It is the writers understanding that the State is working towards a color
standard. In an effort to provide supportive documentation, this office will be collecting color
and copper samples twice a month for a period of six months from the effluent, at the confluence
of Little and "big" Rockfish Creeks, upstream from Little Rockfish on Rockfish Creek at
Highway 17, and downstream from Little Rockfish at the I-40 ambient station. At the end of
six months it will be determined if further data is required.
Although color monitoring was recommended by Instream Assessment and copper limits
were advocated by the WIRO Regional Supervisor during permit modification in December
1991/January 1992, these recommendations were not included in the final permit. It is the intent
of this memo to reemphasize the problem of elevated levels of copper, as well as the increased
detection of highly colored waters in Rockfish Creek. While it is known that the color impacts
are from Stevecoknit, it is suspected that the elevated copper levels are a result of this facilities'
discharge as well. Placement of limits on effluent copper levels and color monitoring are
recommended when Stevcoknits' NPDES permit is reviewed/renewed in 1996 (if not before).

Abbreviations: n=number of observations; > Det=number of observations greater than the detection limit; > Crit=number of
observations greater than the criterion; N/S=No sample; N/C=No Criteria; AL=Action Level
Notes: Median values are calculated using the detection level for samples classified as below detection. The Median value for
Fecal Coliform is actually the Geometric Mean value. Data includes only surface samples. Samples recorded at less than
detection are considered at the detection level for this summary.

MEMORANDUM
TO: Lisa Tabor, Groundwater Section
FROM: Dianne Reid
RE:
Monsanto, ICI Films, Wellman Natural Attenuation CAP
ervykotA
Per your request I have reviewed the information on the Monsanto, IQ Films, and
Wellman groundwater discharge. Surface water quality standards must be met in the
seepage from the bank. This statement is based on the definition of groundwater (15A
NCAC 2L .0100).
I also looked at the data you provided to see if surface water quality standards are
being exceeded. The portion of the Cape Fear River into which the seep runs is classified
C waters. The following table presents the highest concentrations found in the seepage
from 1994 (memorandum from Environmental Sciences to Fayetteville Regional Office
dated February 15,1994) and 1995 (Monsanto monitoring data) and the applicable water
quality standards.

** Data from February 15,1994 DEM memo and Monsanto sampling November 15,1995.
t NC standard for water supplies is 0.8 ug/1. Since this portion of the Cape Fear is not water supply, this
criteria was developed per 15A NCAC 2B .020&
Division of Environmental Management Page 1 Water Quality Planning Branch

Monsanto Natural Attenuation CAP April 16,1996
Lisa Tabor
There are five contaminants which exceed the applicable.water quality standards.
Those contaminants are listed below.
• cyanide
• 1,2-dichloroethylene
• 1,1-dichloroethane
• tetrachloroethylene
• zinc
Several of these concentrations are close to the applicable standard and may be not be
significantly different from the standard. Of the contaminants listed for 1995, only
tetrachloroethylene concentrations (66 ug/1) were above the surface water quality criteria of
8.85 ug/l.
The Fayetteville Regional Office water quality staff should be consulted regarding any
further actions necessary to protect surface water quality.
If you have questions, then please call me at 733- 5083 extension 568.

MEMORANDUM
TO: Carla Sanderson
THROUGH: Dave Goodrich
FROM: Jeanette Powell Y.,
SUBJECT: NC0003719
Monsanto Company
Waste Load Allocation Request
The enclosed information outlines the methods and procedures used to determine NPDES
permit limits for Monsanto Company under their proposed flow expansion. Limits
indicated are summer limits and winter limits will be double the summer value. In
reviewing the following information, keep in mind that the Monsanto wastewater treatment
plant has several waste stream components, including wastewater from two other facilities:
ICI and Wellman. The data considered cover a study period from April 1993 to May 1994,
which was identified as a "representative period" by the company. Note that the month of
March 1994 encompassed a plant upset.
The NPDES group would like to request a meeting to discuss this wasteload allocation
request prior to the scheduled April 19, 1995 site visit.
1. BOD5 Limits
The BOD5 limits were determined using a combination of calculated BAT limits for the
Monsanto wastestream and the OCPSF effluent guidelines (40 CFR 414) for the Wellman
and ICI wastestreams. This approach began with a preliminary review of the submitted
wastestream data which revealed no correlation between BOD5, production, or flow.
Therefore, calculation of BAT limits was based on the removal efficiency of the wastewater
treatment plant, OCPSF guidelines, and an assumed linear relationship between mass and
production. The BOD5 loading from domestic waste, estimated at 2 lb/day, is considered
to be negligible for purposes of calculating monthly average and daily maximum limits.
A. Monthly Average
The Monsanto portion of the wastestream consists of two discrete components: The main
process stream (Monsanto Tech) and centrifuge spent wash (CSW). There is no direct
BOD5 data provided in the engineering proposal for either component, but COD and flow
are reported for each. The CSW discharges through a SBR, for which specific CODBOD5
relationships were provided by the facility. Therefore, the influent BOD5 loading frorp the
CSW was determined using the average monthly COD data provided in the Yearly Influent

Summary and the relationship Influent BOD5 = Outlet COD * 0.1225, which was provided
by the facility.
The influent BOD5 loading for the Monsanto Tech wastestream was determined using the
average monthly mass balance data provided in the NPDES permit application. The flow
diagram (Existing Fayetteville Waste Treatment System) provided in the application
indicates that BOD5 samples collected at the chem lift station (indicated as A. Chem Lift)
consist of combined Monsanto Tech and Wellman flow components. Since BOD5 data
was provided for the Wellman flow component, the Monsanto Tech BOD5 was calculated
by subtraction of the monthly average Wellman Chemical BOD5 from the Chem Lift BOD5.
Using the data provided in the Engineering Proposal for NPDES Permit Application, the
computed BOD5 influent for Monsanto, and BOD5 data provided for ICI and Wellman, a
spreadsheet was created which computed the actual monthly removal efficiency of the
wastewater treatment plant. Excluding the month of March 1994, when a plant upset
occurred, the actual removal efficiency for each month in the study period was in excess of
99% (March 1994 had a 89.9% removal efficiency).
An assumed linear relationship between mass and production was applied to determine the
total predicted Monsanto influent BOD5 by summing the Monsanto Tech and CSW influent
BOD5, multiplying by the proposed maximum production (6182000 pounds per month)
and dividing by the actual monthly production. The maximum monthly BOD5 influent is
computed to be 14733 lb/day. Holding the wastewater treatment plant BOD5 removal
efficiency at 99%, the maximum Monsanto BOD5 monthly average is then computed to be
147.31b/day.
The monthly average BOD5 is then determined by summing the computed monthly average
BOD5 from Monsanto, Wellman and ICI. Wellman and ICI are subject to the OCPSF
guidelines (40 CFR 414, Subparts C and D, respectively), which were used to calculate the
monthly average BOD5 component for each facility. Wellman and ICI monthly average
BOD5 is 0.751b/day and 52.04 lb/day, respectively. Therefore, the cumulative monthly
average BOD5. is 200 lb/day.
As detailed in the March 20, 1995 memo from Dave Goodrich to Steve Tedder regarding
proposed limits for Monsanto WWTP expansion, other options investigated for
determining monthly average BOD5 included, but are not limited to, the following:
Assuming a BOD5 removal efficiency of 99%, an increase in Monsanto's production
by 50%, and an increase in ICI's flow by 30%, the predicted BOD5 mass loading to be
discharged was computed. This loading ranges from 99.161b/day to 207.74 lb/day.
Based on this computation, BAT was determined to be 207.74 lb/day which is similar
to the 2001b/day BOD5 limit based on application of the guidelines for the OCPSF flow
and the calculated BAT for Monsanto's contribution to the discharge.
B . Daily Maximum
Data from DMR's for the months corresponding to the study period of April 1993 through
May 1994 were used to determine the actual ratio of the daily maximum to the monthly
average BOD5. The highest ratio is 2.3, as is shown on the attached effluent ratio table.
This ratio is employed as a multiplier for the monthly average of 200 lb/day to determine
the BOD5 daily maximum limit of 460 lb/day.
Other options investigated for determining daily maximum BOD5 included the following:
Page 2 of 4

(i)
The Monsanto BOD5 influent was determined as in the monthly average
calculations, with the exception of using the high monthly BOD5 for Well Chem
and Chem Lift instead of the monthly average used previously. The CSW
component was still based on monthly average values since the Yearly Influent
Summary does not provide high monthly COD for Monsanto CSW. The daily
maximum effluent BOD5 for Wellman and ICI is calculated using the applicable
effluent guidelines. Holding the 99% removal efficiency applied in the monthly
average calculations, the total effluent BOD5 at 99% removal ranges from 252.01
lb/day to 903.77 lb/day. Therefore, the daily maximum BOD5 would be rounded
down to 900 lb/day. This method of calculation was not used as the effluent
information applied was based on monthly averages. This underestimated
removal efficiencies.
Assuming that the effluent guidelines in 40 CFR 455.22 (pesticide
manufacturing) are directly applicable to Monsanto, who is exempted from these
guidelines, the guideline ratio of 4.625 (monthly average/daily maximum) was
applied to the Monsanto component of the monthly average BOD5 (147.21
lb/day). The ratio of 2.6 (monthly average/daily maximum) in the OCPSF effluent
guidelines was applied to the monthly average BOD5 from ICI and Wellman'?
(52.79 lb/day). The application of the monthly average/daily maximum ratios in
the effluent guidelines results in a total BOD5 daily maximum of 822 lb/day
which would be rounded down to 800 lb/day. This approach was abandoned
since it would be inconsistent to consider the guideline allotment for Monsanto's
contribution to the discharge.
2. COD Limits
The monthly average COD limit is based upon a 90% removal efficiency. This assumed
removal efficiency is significantly lower than the 99% used in the BOD5 calculations
because the removal efficiencies for COD are more variable than those for BOD5. The
actual COD removal efficiencies calculated range from 93.88% to 97.27%. At 90%
removal efficiency, the maximum potential effluent COD is computed to be 4981 lb/day.
This number shall be rounded up to a COD monthly average of 5000 lb/day.
Data from DMR's for the months of April 1993 through May 1994 were used to determine
the actual ratio of the daily maximum to the monthly average COD. The highest ratio is
1.6, as is shown on the attached effluent ratio table. This ratio is employed as a multiplier
for the monthly average of 5000 lb/day to determine the daily maximum limit for COD of
80001b/day.
3. NH3-N Limits
Monsanto is proposing a summer NH3-N limit of 351b/day in conjunction with their flow
increase to 1.3 MGD. The facility is currently permitted at a monthly average of 231b/day
with a flow of 0.859 MGD. The proposed NH3-N limit corresponds to an equivalent mass
to flow ratio as that which is currently permitted. DMR data for the past 2 years indicates
that the maximum reported NH3-N value is 12.83 lb/day. Given these considerations, the
NPDES Group agrees that a monthly average limit of 35 lb/day NI1-N is reasonable, and
should be permitted with a daily maximum of 701b/day NI1-N.
Page 3 of 4

4. OCPSF Limits
Under the expansion proposal, ICI will be manufacturing a new product line and increasing
flow. Therefore, the NPDES group suggests that the list of OCPSF parameters in 40 CFR
414, Subpart I may need to be reinstated at a frequency which should be based upon
findings during the currently scheduled April 19, 1995 site visit. Daily maximum and
monthly average limits are computed for these OCPSF parameters in the attached
spreadsheet.
5. TSS Limits
Monsanto is proposing to reduce their TSS summer monthly average limit from the
currently permitted 6601b/day to 4571b/day. Given that the facility will be reducing TSS
discharges while increasing flow, the proposed monthly average limit of 4571b/day TSS
would seem acceptable. A multiplier of 2.0 was used in the current NPDES permit to
determine the TSS daily maximum. Accordingly, the daily maximum for this permit cycle
shall employ the same factor, making the daily maximum TSS 914 lb/day.

NOTES:
* Influent is predicted by dividing combined Monsanto influent by production, and multiplying by 6180 (maximum proposed
production).
** Predicted
ICI influent is based on a predicted loading factor of 1.3.
I
*** Predicted flow effluent is the sum of Monsanto's average flow increased by a factor of 1.5, Wel!mans average flow, and ICI's average flow increased.
b a factor of 1.3. The sum is then multiplied by the ratio of the effluent flow to the total influent flow.

DIVISION OF ENVIRONMENTAL MANAGEMENT

NPDES'GROUP
March 20,1995
MEMORANDUM
To: Steve Tedder
Water Quality Section Chief
Through: Don Sa
Technical Support Branch Assistant Chief
Coleen Sullins
Permits and Engineering Unit Supervisor
From: Dave Goodrich
NPDES Group upervisor
Subject: Proposed Limits for Monsanto WWTP Expansion
NPDES Permit #NC0003719
Cumberland County
After reviewing the preliminary information provided by TRC Enivronmental Corporation
(Monsanto's consultant) and discussing permitting issues with you and Water Quality Section staff, I
would offer the following comments regarding the development of limits for this facility.
There are three general methods of developing limits for permits:
1) Base limits on model results.
2) Base limits on BPJ.
3) Base limits on BAT.
The existing permit limit of 350 lbs/day for BOD5 (summertime limit) was derived through a
combination of #1 and #3, although it was primarily the BAT limits which were suggested by
Monsanto.
EXISTING WATER QUALITY CONCERNS
Ambient monitoring data are collected by the Division in the mainstem of the Cape Fear River on a
monthly basis. These data indicate that dissolved oxygen levels are depressed in the area of
Monsanto's discharge to levels below 6 mg/1 under summertime conditions. Instream BOD5
concentrations are also much higher in the Cape Fear River mainstem when compared to nearby
rivers like the Black and South Rivers which do not have significant point source impacts. It should
be noted that the ambient data reflect existing loading from point and non -point sources as opposed to
permitted loading to this system.
Facility instream data are also collected which show levels of DO below the standard on the
mainstem of the river (see attachment). It is possible that these data don't corroborate the

information collected by the Division as a result of differences in the time of day in which samples
are collected and/or the effect of algal activity upstream of the lock and dams.
QUAL2E MODEL RESULTS
Although model results are not finalized, Monsanto discharges to the beginning of a DO sag which is
predicted to depress levels of oxygen below the standard {see attachment). Monsanto is one of many
discharges which contributes to this sag. The significance of this finding is that existing permitted
loading is Lut predicted to protect the dissolved oxygen levels in the Cape Fear River basin.
BPJ CONSIDERATIONS
Over the past few years, the Division has been assigning limits no less stringent than 12 mg/1
(summertime BOD5) and 2 mg/1 (summertime NH3) to all expanding domestic facilities
upstream of Lock and Dam #1 on the Cape Fear River. Although these limits were derived
from preliminary modeling evaluations, the 12 and 2 limits are considered "BPJ" since they
have been applied to virtually every expanding discharger without regard to total loading to
the system. It was the concensus of Water Quality Section staff that these limits are
appropriately applied to municipal and domestic wastewater discharges only.
Another consideration was to .examine what the Division • was requiring other similar
industrial discharges to meet in this area. DuPont is an-OCPSF discharger in the proximity of
the Monsanto discharge with a flow limit of 2 MGD and a BOD5 summertime limit of 175
lbs/day .(equivalent allowable concentration of 10.5 mg/1 at design flow). After reviewing
information about the specific operation of this plant and type of wastestream being treated, it
was decided by staff not to recommend equivalent loading be given to Monsanto based purely on
this type of "BPJ".
DETERMINATION OF BAT
The simplest way to predict mass limits based on BAT would be to calculate average
concentrations of BOD5 which are currently being discharged and extrapolate this
concentration to the requested permitted flow limit. Based on the data provided by Monsanto,
the average concentration of BOD5 in the effluent is 5.8 mg/1 (summer) and 10.3 {winter -
excluding March 1994). This would equate to mass effluent limits of 63 lbs/day (summer) and
112 lbs/day (winter). However, is this an appropriate method to use when determining a BAT
limit? In this case, it is probably not. Since production and wastewater flow are not increasing
proportionately, Monsanto will most likely experience an increase concentration of influent
BOD5. The idea of averaging effluent concentrations also does not provide for operational
variations at the facility. Therefore, in order to calculate limits based on BAT, two factors
were determined:
• Removal efficiency of treatment system
• Relationship between production and resultant predicted influent BOD5 loading
The assumption of a removal efficiency of the treatment system is an important element in
determining what type of treatment is reasonably achieved at a given WWTP. Although a
difference of one or two percentage points would appear to be inconsequential, this is not the
case. For example, in considering a BPJ limit of 120 lbs/day, removal efficiencies of 98% and
99% were assumed in order to calculate the mass of influent BOD5 which could be treated by
the WWTP. The results were:

Effluent Limit
% Removal Assumed . Max. Influent Mass which
could be accepted by the
WWTP
120 lbs/day
120 lbs/day
98%
99%
6000 lbs/day
12000 lbs/day
This determination, then, is extremely important, and was a focus of the analysis to recommend
BAT limits. Based on information supplied by the company, the removal efficiencies for
Monsanto's WWTP are listed in the following table:
Date Observed Removal Efficiency
Apr 1993 99.6%
May 1993 99.7%
Jun 1993 99.8%
Jul 1993 99.8%
Aug 1993 99.8%
Sep 1993 99.6%
Oct 1993 99.7%
Nov 1993 99.7%
Dec 1993 99.6%
Jan 1994 99.3%
Feb 1994 99.0%
Mar 1994 89.9%
Apr 1994 99.4%
May 1994 99.4%
This period of time was presented to the Division by Monsanto as representing a typical
production period and was also assumed to represent the range of treatment capability. Also,
note that the March 1994 removal efficiency was a result of a major plant upset which was
corrected by the company and not represented in the data collected during the following month.
It was not considered a representative removal efficiency in this analysis. Monsanto has
committed to increasing treatment of BOD5 at their Fayetteville facility and should be able to
do so with the proposed changes to the wastewater treatment system (see attachments).
Summertime removal efficiencies range from 99.4 - 99.8%. However, again realizing the
potential for operational variation, a removal efficiency of 99% was assumed in this analysis.
This matches the lowest removal efficiency documented in the representative months above
and is also quoted as the removal efficiency in all four of the treatment methods performed
during the company's treatability study.
Since ICI and Wellman are both OCPSF facilities, allowable BOD5 limits are determined
using the Federal Guidelines (40 CF13. 414). Based on predicted wasteflow and the highest
monthly average flow observed during the representative time period, 52.8 lbs/day should be
allowed for these wastestreams. Measured influent values for Monsanto were increased by a
ratio of lbs/day of BOD5 to lbs/day of product produced multiplied by the maximum predicted
production rate in a single month. The resulting influent values ranged from 5664 lbs/day to
14733 lbs/day. Assuming the highest predicted monthly mass (147331bs/day) and a 99%
removal efficiency, the BAT limit for Monsanto's contribution to the treatment system would be
147.3 lbs/day. Therefore, when added to 'the allowance from the -OCPSF facilities (52.8
lbs/day), the Division should require Monsanto to meet a limit of 200 lbs/day.
These values were checked by ignoring the OCPSF requirements and increasing the influent
loading from ICI by 30%. Effluent values from the resulting worst -case month <i.e., BAT limit)
was 208 lbs/day which is comparable to the 200 lbs/day limit recommended.

MONSANTO: EXISTING TREATMENT WORKS
The existing Monsanto treatment system consists of a spill basin (1 MG - seldom used), an equalization
basin (4 MG), oil/water separator, pH adjustment, two aeration basins (0.4 MG, 1 MG), two clarifiers
(90 ft - in use, 50 ft - not in use), sandfilters-(not in use), chlorine contact chamber (not in use), an aerobic
sludge digestor, a sludge storage basin and sludge drying beds. Additionally, Monsanto has side -stream
treatment systems for some of their more highly concentrated waste stream (centrifuge spent wash
wastewater) that are not in use, including two sequencing batch reactors and an incinerator. Currently,
waste streams from different production areas and sanitary contribution are brought into the treatment
system at different points. For example, the centrifuge spent wash is added to the treatment system
after the equalization basin and the sanitary contribution is added at the second aeration basin
MONSANTO RECONFIGURATION:
Monsanto is proposing to re -pipe the existing influent waste streams to the head of the wastewater
treatment plant and modify the existing in -ground components to obtain better levels of treatment. The
reconfiguration of the system still does not propose to use all of the treatment components that are on -
site, specifically, the sequencing batch reactors, the 50 ft clarifier, the sandfilters, the chlorine contact
basin and the incinerator are not proposed to be used. Additionally, the function of the existing
remaining units will be modified:
Oil/water separator (same function, propose to modify slightly)
Spill Basin - converted to equalization basin (1 MG - permitted flow requested is 1.3 MGD,
therefore, size as an equalization basin is more than sufficient)
Equalization basin - converted to primary aeration basin (4 MG capacity)
Aeration basin - proposing to convert one of the existing two aeration basins into a sludge digestor,
the initial proposal is to convert the larger.(1 MG) to a sludge digestor and use the smaller
aeration basin (0.4 MG) in series with the new primary aeration basin (4 MG). Proposal
also includes piping to bypass the secondary aeration basin and potentially not use it in the
treatment scheme.
Clarifiers - continue to use the 90 ft diameter clarifier, not proposing to use the smaller clarifier.
This reconfiguration will consist of relocating the pH adjustment to the lift station at the head of the
treatment plant, adding four 7.5 HP mixers to the new equalization basin, relocating existing aerators to
the new equalization basin and adding six additional aerators to the primary aeration basin.
TREATMENT DESIGN CONSIDERATIONS
A comparison of the existing design parameters to the reconfigured system supports the determination
that the system will provide equal or slightly better levels of treatment. The current system is
providing a detention time of 74 hours in the aeration system, producing average effluent concentrations
of 8 mg/1 BOD5 and 1 mg/1 NH3. Under the expansion and reconfiguration the aeration detention time
will be 80 hours. The 90 ft. clarifier is also adequately sized to handle the loading rate that is
projected to occur. Therefore, it appears that the system will provide similar levels of BOD5 /NH3
removal as those currently being achieved. Proposed permit limit“BODS = 200 #/day, or -18 mg/1)
should provide an adequate window for compliance.

Dear Mr. Goodrich:
In accordance with 15A NCAC 21H.0100, please find enclosed three copies of
Monsanto Company's NPDES permit application and the processing fee of $400.
As discussed with you during several meetings, the major differences associated with
the expansion plans involve additional process equipment as well as modification to the
waste treatment system to accommodate this expansion.
Monsanto neither anticipates nor requests any modifications to the existing permit
associated with the storm water requirements, outfall #003, the biomonitoring and the
OCPSF requirements.
The information contained in this application is a request to allow Monsanto
Company to discharge, via outfall #002, the parameters at the levels reflective of
Monsanto's own expansion needs while also accommodating the needs of the previously
announced ICI Americas expansion project.
The information contained in this application, as well as the Engineering Proposal
document (Ref: TRC No. 18-153), are both regarded by Monsanto Company to be company
confidential information. It is, therefore, expected that the information will be treated as
such.

No. 13 - Activity Description
Item 213a
Discharge 002
Section II
Item 213a
Contributions to Discharge 002 result from herbicide manufacturing activities as well as wastes
received from the adjoining facilities (ie., ICIA and Wellman, Inc.) that produce polyester resins
and fibers. Laboratory and sanitary wastes are routed to the biological treatment system and
discharged via 002.
Polyester resin is manufactured from ethylene glycol and dimethyl terephthalate by a
polymerization process. The base polyester resin is spun into continuous filament.
This system also handles wastewater which does not come in contact with process contaminants.
These non -contact streams have been identified in the attached flow diagrams and are listed as:
1) Backwash Pond Blowdown (Water Treatment Settling Pond)
2) Demineralized Water Treatment Blowdown
3) Boiler Blowdown
4) Cooling Tower Blowdown
The herbicide intermediate, N-phosphonomethyl imino-diacetic acid, is converted to N-
phosphonomethyl glycine, concentrated in an evaporator, separated and washed in a centrifuge.
The cake is stored either wet or dry. The wet material is separately reacted with isopropyl -
amine and then formulated in a water solution with a surfactant and packaged. The dry material
is shipped to customers.
The plant -wide stormwater collection system, which separately collects stormwater runoff from
buildings and streets, discharges stormwater via outfall #001. Outfall #001 will be sampled and
analyzed according to the permit conditions.
Supporting facilities and activities include water treatment, waste treatment systems,
warehousing, raw material storage, maintenance facilities, and administrative offices.

No. 15 - Waste Abatement
Item 215a
Discharge 002
Section II
Item 215a
In process waste abatement practices include separate process drainage systems, segregation of
water, use of surface condensers, emergency waste storage facilities, special seals on pumps,
minimization of air blow transfers, centrifuge wash recycle, recycle of water, use of multieffect
evaporators, and monitoring of effluent. To allow year-round biological treatment of glyphosate
using GDA (Glyphosate Degrading Activity), a smaller scale -- SBR (Sequential Batch Reactor)
treatment tank and associated equipment is installed for pretreatment of glyphosate prior to
entering the aeration basins. However, the operation of SBR is limited to an as needed basis
and is not normally used.
The glyphosate waste incineration unit is in place, if needed, as a backup means of destroying
glyphosate bearing waste. The incineration unit has not been in operation for a number of years.
Effluent from the polyester and herbicide manufacturing areas is discharged to an influent pump
station (identified as Chem Lift in the Engineering Proposal schematics) with pH adjustment.
Wastewater is pumped to an oil/water separator and then flows to an aerated equalization basin
with pH adjustment capabilities. The equalized wastes then flow to the activated sludge
biological treatment system. The activated sludge system consists of primary and secondary
aeration followed by and clarification. Excess sludge is aerobically digested and then dewatered
on sand drying beds prior to land application, or liquid sludge is land applied. Sanitary wastes
are also treated by the activated sludge process. Effluent may be disinfected by chlorination
prior to discharge.
Schematics of the existing and proposed waste treatment systems are attached.

The following list of chemicals further identifies compounds which may be present in the
discharge:
a) Ammonia may be added as a nutrient to the biological treatment plant and may be
present at low levels in the sanitary wastewater. It will be neutralized before discharge.
b) Calcium hydroxide may be used to neutralize and precipitate materials from a waste
stream. It will be neutralized before reaching the effluent.
c) Chlorine may be used to disinfect wastewater before discharge, to meet the fecal coliform
standard.
,,.,, d) Formaldehyde is in the wastewater influent to the biotreatment system for removal;
however, virtually all of it is biodegradable.
e) Formic acid is in the wastewater sent to the biotreatment system for removal.
f) Salts of phosphoric (and phosphorous) acid will be present in measurable quantities, after
neutralization, in the wastewater effluent because of the nature of the manufacturing
sources.
g)
Sodium hydroxide is used as a neutralizing chemical and its salts, for example a sodium
phosphate, will be in the wastewater effluent.
h) Sulfuric acid, as a neutralized salt such as sodium sulfate, will be in the wastewater
effluent.
i) During chlorination trace quantities of cyanogen chloride have been detected in the plant
outfall.
Samples of the waste treatment effluent, outfall 002, were collected at Monsanto's Fayetteville
Plant, Fayetteville, North Carolina, during 1993 and 1994 by plant personnel. The samples
were submitted to outside testing agencies (*) for analyses. Analytical results of the 002 outfall

MEMORANDUM
To: Ruth Swanek
Instream Assessment Unit Supervisor
Through: Coleen Sullins C
Permits and Engineering Unit Supervisor
From: Dave Goodrich'
NPDES Group Supervisor
Subject: Limits for Monsanto WWTP Expansion
NPDES Permit #NC0003719
Cumberland County
After reviewing the preliminary information provided by TRC Enivronmental
Corporation (Monsanto's consultant) and discussing permitting issues with you,
your staff, and the Fayetteville Regional Office, I would like to offer the following
comments regarding the development of limits for this facility.
There are three general methods of developing limits for BODS and NH3 in this
permit:
1) Base limits on QUAL2E model results.
2) Base limits on BPJ (i.e., 12 and 2 or base on consistency with existing permits).
3) Base limits on BAT.
The existing permit limit of 350 mg/1 for BODS was derived through a
combination of #1 and #3, although it was primarily the BAT limits which were
requested by Monsanto. I suspect that it will be worthwhile to look at all three
methods for this proposed expansion prior to the March 14,1995 meeting. The
NPDES Group will attempt to develop limits based on BAT which will be
presented at the March 14th meeting. As for the model results and the BPJ
discussion, I would like to discuss answers to the following questions in
preparation for the meeting:

Page -2-
Memo to Ruth Swanek
Limits for Monsanto WWTP Expansion
March 12, 1995
What do existing D.O. data from DMR's and ambient monitoring document?
What does the QUAL2E model demonstrate?
What will the model support in terms of limits?
Can we use the model to argue BAT/BPJ approach?
Vogt's Level B model determined that limits of 20 mg/1 (BOD5) and 4 mg/1 (NH3)
would protect. What mass did these concentrations represent at the time?
What is the basis for DuPont's BOD5 limit?
As I mentioned to Steve Bevington, I invited Michael Wicker to this meeting
since this discussion will have a direct bearing on the facilities in his region. I
realize that the intent of this meeting isn't only to discuss the decisions which
need to be made at Monsanto, but I hope this memo can serve as a tentative
"agenda" for this portion of the meeting. Let me know if you have questions or
comments.

1.0 Proposed Waste Discharge Origin, Type and Flow
,r, 1.1 Summary of Activities Producing Waste
Monsanto Company's Fayetteville, North Carolina Plant, located on Highway 53 East - 210 South
on Cedar Creek Road, produces the crop control chemical Roundup. The Fayetteville Plant, a
part of Monsanto's Crop Chemicals Division, has been in operation since 1981. Monsanto
Company also owns and operates its own water utilities, including a water treatment plant and
wastewater treatment facilities. In addition, Monsanto supplies water to and treats wastewater
from adjoining facilities owned by ICI Americas Inc. (ICIA) and Wellman Inc. (Wellman).
0"'' Contributions to existing NPDES Discharge 002 result from Monsanto's herbicide manufacturing
activities as well as wastes received from these adjoining facilities that produce polyester resins
and fibers. Process and sanitary wastes from the three facilities (i.e., Monsanto, ICIA and
'`' Wellman Inc.) are transported to the biological treatment system and discharged via 002.
ICIA, in conjunction with Wellman, Inc., produces polyester fiber. Polyester resin is
''' manufactured from ethylene glycol and dimethyl terephthalate by a polymerization process. The
base polyester resin is spun into continuous filament.
Pul
At the Monsanto facility the herbicide intermediate, N-phosphonomethyl imino-diacetic acid, is
converted to N-phosphonomethyl glycine, concentrated in an evaporator, separated and washed
in a centrifuge. The cake is stored either wet or dry. The wet material is separately reacted with
ram
isopropyl -amine and then formulated in a water solution with a surfactant and packaged. The
dry material is shipped to customers.
These facilities also generate wastewater which does not come in contact with process
contaminants. These non -contact streams include backwash pond blowdown (water treatment
settling pond), demineralized water treatment blowdown, boiler blowdown and cooling tower
blowdown. In addition, there are sanitary waste stream components from these facilities.
PEI The projected wastewater treatment facility design flow is 1.3 million gallons per day (MGD).
The design flow represents an increase in the existing average monthly discharge limitation
(0.859 MGD) of 0.441 MGD.

1.2 Proposed Expansion
NPDES-EngineeringProposal Monsanto Company
March 15, 1995 Confidential Information
Monsanto Company is proposing to put in place expansion plans in order to meet business needs
triggered by substantial demand worldwide. The Fayetteville Plant was selected for Monsanto's
business expansion based on the existing supporting utilities, successful operations of the utilities
and capacity to integrate this expansion, while fulfilling the worldwide market demand.
r..r The scope of the proposed expansion will increase the overall production capacity of the
Monsanto Fayetteville Plant by approximately 200 percent from the current base, resulting in a
production increase of three times the present production rate. The ICIA proposed expansion will
run increase their overall production capacity by approximately 100 percent from the current base,
resulting in a production increase of 2.0 times the present production rate. Actual production
rates for the last three years and five year projected production rates are included in Appendix
pul A.
Monsanto proposes to install the project at the Fayetteville facility so that the technology and
chemistry involved is identical to the present conventional glyphosate manufacturing technology
at this location. This expansion will therefore represent an "add -on" process, parallel to the
current process. All unit operations involved are identical to the present and as such will not
run introduce other unknowns from the chemical and technological points of view, other than
operational changes. The process expansion will require upgrades or increase in operational
efficiency at the raw material handling, processing, finished goods, packaging, and shipping areas,
rsrl as well as the wastewater treatment facilities in support of the overall expanded operations at the
plant.
rim The simultaneous Monsanto and ICIA expansions will require Monsanto to upgrade its waste
treatment facilities in order to meet the associated increase in waste flow and loads.
2.0 Summary of Wastewater Treatment and Disposal Options
run
2.1 Alternative Waste Treatment and Disposal Options Considered
F-1 The following treatment and disposal scenarios were evaluated by the Monsanto's Environmental
Operations group:
14P1 Option 1 - Pollution Prevention (including source reduction and recycling)
Option 2a - Upgrade existing activated sludge plant - Upgrade existing structures,
increase aerator efficiency and treatment efficiency
Option 2b - Pretreatment or no treatment and discharge to the Fayetteville POTW
Option 3 - Reuse
Option 4 - On -site spray irrigation

A letter from Environmental Operations that summarizes the treatment options investigated is
1411 included in Appendix B.
rem 3.0 Description of Proposed Treatment Works
The facility expansion will result in increases in the hydraulic load to the waste treatment facility
as well as increases in the level of BOD, COD and TSS loading. However, based on the pilot
treatability study, the BOD, COD and TSS loadings will not increase proportionately to flow.
To accommodate the projected flow and loading, the existing wastewater treatment facility will
1411 be upgraded to increase the efficiency of the activated sludge treatment process.

TREATMENT OPTIONS

TRC Environmental Corporation

OPTIC:RV Ts DI$CRA :GE OF FAYETTEVILLE WASTEWATER PO _LtITANTS
"m ].. The primary option: reviewed for discharge of wastewater pollutants
from the Fayetteville operations was pollution prevention. This
included source reduction as well as recycling. This option was
m, used to significantly reduce the pollutants sent to the waste
treatment operations. This included process modifications that
reduced impurity make in the reactor. it also included various
purification operation improvements that also reduced the
mm pollutants discharged. Recycle was also incorporated into this.
This recycled not only wastewater, but also recycled impurities
back through the process. This also reduced the production of
mm
pollutants.
2. This was followed by the option to reduce the wastewater effluent
pollutants by extensive biological treatment. An option considered
tom, was the discharge of wastewater to the local POTW. This option was
rejected in favor of on -site biological waste treatment with the
systems that were designed specifically to treat these pollutants
at a much higher efficiency than would be afforded by the POTW.
mm The Mionsanto Fayetteville wastewater treatment facility was
recognized by the EPA as the Best Practical Technology (BPT) and
Best Conventional Technology (BCT) in comments submitted in support
of the Pesticide Effluent Guidelines. The treatment facility of
P' this plant will average 99%. Specific SPA comments are as follows
at FR56, 50651:
rim "EPA agrees vi::h these comments. The wastewater treatment
technologies =stalled at the facilities manufacturing these
it PAIs are equivalent to the SPT technology, i.e., the
technologies include both in -plant treatment to control PAIR
and end -of -pipe: biological treatment to control BOD and TSS.
rum Because these manufacturers are meeting the BPT-level
limitations oil. BOD, TSS and pH, it appears that these
technologies are being well -operated."
M' 3. Other options thc- t were considered were the subsequent reuse of
water after waste treatment, either internally or for external use.
It was determined that this water was not suitable for reuse within
mm the plant becaus,v of the co -mingling of pollutants that would
interfere with the reaction process, and could result in the
increased product ion of pol' lutants . It also could affect the
safety of the process due to possible side reactions.
mm
4. Use of the water for irrigation was also considered, however, due
to the local soil conditions, the amount of wastewater available
and build-up of salinity, this option was also rejected.
MR
5. The attached chart. shows the significant reductions in wastewater
pollutants afforded by the pollution prevention options noted
P, above. All process effluent will also be processed by a state-of-
the-art wastewater treatment unit that uses the Best Practical
Technology and Best Conventional Technology to further reduce the
discharge of wastewater pollutants.

WASTEWATER TREATMENT FEASIBILITY STUDY FOR
PROPOSED FAYETTEVILLE PLANT EXPANSION
INTRODUCTION
In support of the Fayetteville Plant bioexpansion project, laboratory studies
were conducted to determine the feasibility of treating the increased
waste using 4 different treatment configurations. .The reactors were all
Eckenfelder design with the series reactors hooked up to external clarifiers
operating with sludge recycle and the parallel reactors using baffles as
clarifiers (Fig. 1). Feed for the reactors (shipped from Fayetteville and mixed in
St. Louis) consisted of pH pit [existing waste not including Monsanto/Wellman
sanitary or glyphosate centrifuge spent wash (CSW)), additional Tech
Overheads and ICI waste, plus CSW. The reactors were first acclimated to
the existing waste and flow. The waste (and flow) was then increased step -wise
fashion until it reached the estimated expansion level (2.5 times increase in
Tech Overheads flow and up to 50% increase in CSW). Also incorporated into
the `projected waste stream" treated by the bioreactors was the increase in
ICI waste due to their expansion project (30% increase in current flow of
existing waste matrix).
EXPERIMENTAL
SERIES CONFIGURATION:
1. The Fay 1-2 series was a traditional series operation with the first stage
scaled to the 3.5 M gal basin and the second stage scaled to the larger of the
existing aeration basins (1.2 M gal). Influent entered the system in the first
stage and sludge was recycled from the clarifier to the first stage. Sludge
production was quite low and the only wasting from these reactors was for
sampling purposes (from the reactors) and TSS in the effluent. The reactors
were operated at 21° C (70° F).
2. The CSW series was set up somewhat differently with the first stage the
smaller of the two stages. All of the centrifuge spent wash (CSW) was added to
20% of the total "expansion" flow and fed into Stage 1. The effluent then flowed
into Stage 2 (which was receiving the remaining 80% of the "expansion flow")
for additional treatment. The first stage reactor was originally designed to treat
only the CSW, but the flow was so low that combined with loss to evaporation
produced a situation where there was no overflow into Stage 2. When this
happened, the salt began to build-up and microbial activity (as measured by
TOC and COD) was retarded. The sludge recycle from the clarifier emptied into
Stage 2 and 100 mi/day from Stage 2 was recycled back into Stage 1 to
maintain the solids level at 4,000 mg/L. There was also some wasting from
Stage 2 in order to maintain the solids level in that reactor at 6,000 mg/L. The
reactors were operated at 21° C (70° F).

PARALLEL CONFIGURATION:
8. The parallel reactor Fay 3 was scaled to represent the 3.5 M gal aeration
basin. It was operated at 28 ° C (84° F). There was no sludge edge recycle stream
since a baffle inside the reactor provided the quiescent zone for clarification
instead of a separate clarifier. Fay 3 was operated with a solids level of 4500
mg/L. Wasting from the reactor was necessary to maintain the solids at the
design level.
4. Fay 4 was operated in identical fashion to Fay 3 except that mixed liquor
solids were maintained at 6,000 mg/L.
The reactors were acclimated for 3 HRTs at each level. Data was then
collected during a 5 day kinetic study on the reactors, the effluent from the
reactors and the feed to the reactors. Samples were all filtered (including
effluent for BOD testing) before analysis.
0.1 RESULTS
Key results of the bioreactor testing are shown in Table 1. BOD treatment
efficiences averaged 99% in all treatment configurations which were evaluated.
COD or TOC treatment efficencies were somewhat more variable but ranged
from 91-98%. Sludge settling was good in all reactors and no significant
florl toxicity was associated with bioreactor effluents.
It must be stressed that bioreactor feasibility studies are used as tools in the
design of activated sludge biological treatment systems. We are designing our
treatment system to average 98% BOD removal and 90% COD removal on an
annualized basis at the proposed expanded production rates for Monsanto and
ICI operations. This is based upon:
1. The historical excellent BOD and COD treatment efficiencies achieved in the
field must be maintained at hydraulic retention times in the aeration basin
reduced from 11 to 5.6 days.
2. Laboratory treatment studies evaluated conditions of annualized production,
not uistaneous peak waste loadings which the biosystem must be able
adequately treat. (Studies to determine peak waste treatment capacities and
associated safety factors are ongoing.)
Fool
3. In our laboratory investigations, we measured only the BOD content of the
treated effluent associated with the soluble fraction. Since we filtered the
effluent samples, we did not measure any BOD which may be associated with
particulates. (Weare also currently investigating in our laboratory the
amount of BOD which may be associated with efluent TSS.)

Yours truly,
Van Bell
