Monitoring shall be performed in addition to facility inspections.
Implementation: Implementation of the Plan shall include documentation of all monitoring,
measurements, inspections, maintenance activities and training provided to employees,
including the log of the sampling data. Activities taken to implement BMPs associated with the
industrial activities, including vehicle maintenance activities must also be recorded. All
required documentation shall be kept on -site for a period of five years and made available to
the Director or his authorized representative immediately upon request.
A. (14) STORMWATER MINIMUM MONITORING AND REPORTING
REQUIREMENTS
Minimum monitoring and reporting requirements are as follows unless otherwise approved in writing
by the Director of the Division of Water Quality:
a. If a facility has multiple discharge locations with substantially identical stormwater discharges
that are required to be sampled, the permittee may petition the Director for representative
outfall status. If it is established that the stormwater discharges are substantially identical
and the permittee is granted representative outfall status, then sampling requirements may be
performed at a reduced number of outfalls.
b. Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry weather
flow shall be performed at all stormwater discharge outfall locations. All visual monitoring
shall be documented and records maintained with the Stormwater Pollution Prevention Plan.
The initial visual monitoring event shall be performed simultaneously with the first analytical
monitoring event and documentation of only this initial visual monitoring event shall be
submitted along with the required analytical monitoring submittal.
c. 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 II, Section
A). Failure to monitor 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, 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.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
approved by the Director no later than January 31 for the previous year in which sampling was
required to be performed.
Permit NC0003719
e. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
f. This permit regulates stormwater discharges associated with industrial activity. Non-
stormwater discharges which shall be allowed in the stormwater conveyance system are:
(1) All other discharges that are authorized by an NPDES permit.
(2) Foundation drains, air -conditioner condensate without added chemicals, springs,
waterline and fire hydrant, water from footing drains, flows from riparian habits and
wetlands, fire -fighting training and fire system testing.
(3) Discharges resulting from fire -fighting.
If the storm event monitored and reported in accordance with this permit coincides with a non-
stormwater discharge, the permittee shall separately monitor and report all parameters as
required under the non-stormwater portion of this permit and provide this information with the
stormwater discharge monitoring report.

MEMORANDUM
TO: Natalie V. Sierra
NPDES Permits and Engineering Unit
FROM: Grady Dobson, Environmental Engineer
Fayetteville Regional Office
SUBJECT: Comments Concerning NPDES Draft Permit No. NC0003719
Monsanto -Fayetteville WWTP
Cumberland County
The draft permit for the Monsanto facility has been reviewed by the Fayetteville Regional
staff. The permit appears consistent with all industrial dischargers going into the WWTP and
follows the Cape Fear River Basin Plan strategy.
Monsanto to our knowledge still owns the property on which the WWTP is located.
Currently construction crews are onsite dismantling all buildings on the complex. The
"Roundup" manufacturing area has already been removed and definitely not in production.
There are currently 5 Monsanto employees left at this facility which includes the WWTP ORC
and Backup ORC. The only wastewater coming from this facility is domestic from these
employees and construction crew.
The Cumberland County new industrial park complex located approximately 2 miles from
the Monsanto facility currently is in the early stages of development. PWC of the City of
Fayetteville has future plans to provide the new park with sewer, however it may still be several
years in the future before this action is finalized.
It is the recommendation that the subject permit be issued.

Applicant Address:

Type of Waste:

Facility/Permit Status:

County:
Cumberland County
BACKGROUND
Monsanto Company's Fayetteville facility produces Roundup®, the company's glyphosate-based
pesticide. The company operates a 1.25-MGD wastewater treatment plant that handles process and domestic
flow from the Roundup® plant as well as from the neighboring DuPont and Wellman plants. DuPont
manufactures polyethylene terephthalate (PET) and Wellman manufactures partially oriented yarn. Process
flows from both facilities fall under the Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF) technical
guidelines (40 CFR 414); the applicable guidelines for DuPont are in Subcategory D-Thermoplastic Resins and
Subcategory C- Other Fibers contains the applicable guidelines for Wellman. Due to the limited nature of the
pesticide technical guidelines (40 CFR 455, Subcategories A and C), the Division of Water Quality has
developed site -specific limitations on a number of parameters of concern, including TSS and ammonia
nitrogen.
REQUEST FOR MODIFICATION
The existing permit has two "phases" — one that covers the period of time between permit issuance and
the shutdown and cleanup of the Roundup® plant and the other which covers the time after cleanup of the
Roundup® facilities. The second phase has limits for the two OCPSF facilities only as well as a smaller flow
limit.
The end date for the first phase of the permit is January 31, 2003, and is based upon estimates given by
Monsanto to DWQ for the estimated time for cleanup of the glyphosate/Roundup® processes. Due to the
drought and unseasonably cold weather, as well as the fact that Monsanto has been manufacturing Roundup®
at this facility for many years (and this is the first shutdown of a Roundup® plant that Monsanto has ever
performed), the site will not be clean by January 31, 2003. There are stipulations in the current permit that
Monsanto must continue to monitor for glyphosate after the January 31 deadline until no glyphosate is detected,
but the Permittee would feel more comfortable with a simple extension of the first phase of the permit. The
Permittee is requesting an additional six months (June 30, 2003) to continue to work on the cleanup of the site.
This seems to be a reasonable length of time and ultimately provides water quality benefits.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the first phase of this permit will end on June 30, 2003 instead of January 31, 2003.

Attention: Natalie Sierra- Sr. Engineer -Permitting
ccc 3'1 r
Dear Ms. Sierra:
Monsanto Company requests a 150 day extension of the first phase of its NPDES permit (No.
NC0003719) for its Fayetteville, NC facility so that the end date of the first phase would be
moved from January 31, 2003 to June 30, 2003.
This request is necessary because of the unanticipated conditions that the wastewater
treatment plant is experiencing. We have been having difficulty maintaining an active biomass
population and consequently anticipate having difficulty meeting the limits of the second phase
of the permit by the current February 2003 deadline. We suspect that the primary cause of
these difficulties is the particularly cold weather the region experienced at the end of November.
This drop in temperature coupled with the changing nature of the wastewater input (due to the
closure and dismantling of major portions of the facility) have destabilized the biomass.
Please know that we have been working diligently to resolve the biomass problems. We have
constructed a steam line from our utility facilities to the WWT works in order to increase the
biomass temperature. We have started adding nutrients to the system.
Although it is possible that the steps we are taking at the WWT plant will resolve the issues we
are currently experiencing in time for us to meet the second phase limits by the end of January
2003, we do not have confidence of this occurring. Therefore, we request the 150-day
extension.

Aerobic Digester # 1 — Plan for Repairing Damage
Dear Messrs. Rawls and Barnhardt:
I would like to document the understanding that Monsanto Company and the Department of
Environment and Natural Resources have reached regarding Monsanto's plan to address the
damage we recently discovered in our Aerobic Digester #1. As was discussed during my
September 27 telephone call with Mr. Barnhardt and in Mr. Rawls' October 08 voice mail
message to me, Monsanto will: (1) have a structural engineer develop repair plans, (2) perform
the repairs according to the plans, (3) obtain a certification from the engineer that the repairs
were done according to his or her plans, and (4) send you a letter confirming the completion of
these steps. Given the circumstances associated with the damage to the Digester, you have
agreed that no further investigation of soil or groundwater in the vicinity of the basin is
warranted.
I appreciate your responsiveness and assistance on this matter. Please contact me at (910)-
433-4205 if you have any follow up questions or concerns.

Dear Ms. Sierra:
Thank you for confirming your position in your March 4, 2002 letter to Deborah Small of Monsanto
Company. By phone today, you indicated that the above -referenced permit is eligible for an
administrative transfer to a new owner provided that the transferee continues the operations of
Monsanto Company without beginning any new process or operation.
I appreciate your prompt reply to my inquiry.
Sincerely,

PHONE 1910J323-3300
Listed below are Monsanto's comments for the "Draft" copy of the Fayetteville NPDES permit
#NC0003719 which you sent to Hope Walters via email.
Item #1
In your cover letter you make reference to Whole Effluent Toxicity Testing. Please specify that this
requirement refers to P/F @ 90% toxicity using acute Fathead Minnow testing versus chronic
requirements. You state that it must remain quarterly due to the facility being a Grade III. In
October 2002 when the facility is lowered to a Grade II, Monsanto requests that sampling be
required annually versus quarterly.
Item #2
Under page 2 of the cover letter you specify BOD and TSS limits will decrease to monthly averages
of 43.4 and 72.5 Ibs/day, respectively. Currently bench tests are being conducted in our St. Louis
research lab to determine the feasibility of these limits. At this time we do not have sufficient data
to ensure our capability of meeting these limits.
Item #3
In the supplement to permit cover sheet, item #1 refers to the plant's physical location. Our street
address is 3468 Cedar Creek Road instead of the previous Hwy 53, south of Fayetteville in
Cumberland County.
Item #4
Also in the supplement to permit cover sheet, item #4 refers to new owner requirements. We
would like clarification regarding change of ownership and new owner requirements. Currently
there are references to a new owner submitting a new permit application, modification and proof of
change of ownership (cover letter, supplement and permit A(5). Monsanto would prefer a change
of ownership notification of some sort only in lieu of permit modification or a new application.
Item #5
Section A (1) Effluent Limitations and Monitoring Requirements. Analysis of conductivity was
added to the effluent sampling. This was not included in the previous permit. We request that this
requirement be removed.
r1
i
Item #6
Currently the sampling location for stormwater analytical and qualitative monitoring is located at
SW-1. SW-1 is located south of the Roundup operations. Once the facility completes the
dismantling of the Roundup operations, is there a need to continue to monitor this outfall? Should
there be stormwater sampling associated with the remaining industrial operations, i.e. DuPont and
Wellman?
Per our telephone conversation, November 8, all of our other questions have been addressed. If
you need further information, please contact me at (910) 433-4242 or Hope Walters at (910) 433-
4237.
