MEMORANDUM
TO: Donald Safrit, Supervisor
Permits & Engineering Unit
FROM: M. J. Noland, Regional Supervisor
Fayetteville Regional Office'
SUBJECT: Request to Eliminate a Downstream Sampling Point,
Monsanto Company, Fayetteville f.'
NPDES Permit No. NC0003719
A request was submitted by the Monsanto Company in Fayetteville, North
Carolina for the elimination of one of the two downstream sampling points
contained in their NPDES Permit No. NC0003719. The downstream sampling point
Monsanto is requesting to eliminate is the sampling point on the Cape Fear
River that is located closest to the facilities outfall. To obtain samples at
this location, Monsanto had been using the abandon conveyor belt/bridge owned
by the Becker Sand & Gravel Company. Recently the Becker Sand & Gravel
Company dismantled the conveyor belt due to the high hazardous liability
insurance cost Becker was going to incur if they allowed the bridge to remain
in place.
The staff of the Fayetteville Regional Office and Monsanto officials
evaluated alternative sampling locations to replace the Becker bridge site,
however no other access private or public could be found that would give good
representative sample data and assure safety to those involved in obtaining
the samples.
Therefore, it is the recommendation of the Fayetteville Regional Office
that a Permit amendment be issued to the Monsanto Company which allows only
one downstream sampling point requirement. If any additional information is
needed, please advise.

Dear Dr. Everett:
The attached letter describes the rationale for which Monsanto had requested a
minor modification to the referenced permit during the summer of 1990. In order to
expedite that request and per N. C. State NPDES modifications rules and criteria, the
attached fee in the form of a $50 check made payable to N.C. State - DEHNR is also
forwarded.
We trust that this will fulfill the needs in facilitating our request. We have also
confirmed visually that the Becker Sand and Gravel suspension bridge has been permanently
disassembled.
Sincerely yours,
H. Van Bell

SECTicf,�L/Ty •
The criterion set forth in the above referenced permit, granted to Monsanto Ag. Co. since October 1987,
requires sampling of the Cape Fear River on a 4 times per month per sample basis. This is done on each
of the two downstream samples, as well as one upstream sample, taken at the stipulated lotions in the
NPDES permit. Over the years Monsanto has continued to comply with the above requirements
successfully. Recently, however, one of the downstream samples closest to Monsanto's outfall, referenced
as Becker Sand and Gravel location, cannot be accessed due to a high sampling hazard identified and
posted as a sign by Becker Sand and Gravel Co. During the month the existence of this hazard has been
brought to our attention by our own sampling consultant. This sample has been procedurally grabbed
while standing on an abandoned suspension bridge. This bridge was originally used by Becker Sand and
Gravel Co. to transport their material across the river by using the conveyor belt system built on this
bridge. This conveyor system. was abandoned sometime ago; however, .bridge remained somewhat
accessible. At present any access to this bridge is not permitted as per the sign posted by the Becker Sand
and Gravel Co. to prevent any mishap or injury.
There appears to be no other viable alternative to sample the river around this location while insuring a
representative sample. In view of this situation and based on the quality of river water on the two
downstream samples, which continue to be well within the stated requirements, Monsanto Ag. Co. requests
the following for your consideration:

This has already been communicated to Mr. M. J. Noland of DEHNR, Wachovia Bank Bldg., Fayetteville.
We trust that you will allow us the request stated in 1) above and will not penalize us for an "incomplete"
DMR for at least the month of July 1990 and thereafter until a viable solution is arrived at based on your
input.
We appreciate your .timely response in this matter.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requests elimination of a downstream sampling point because the access bridge has been
destroyed. It is recommended that this request be granted. This means only the station located just
upstream of Lock and Dam #3 will be sampled.
It should be noted that this WLA fact sheet is for the 002 pipe only. After consulting with
Matthews (Aquatic Toxicology), it is recommended that the facility be required to implement a
quarterly, 24-hour acute toxicity test using Fathead Minnows. Since the last permit was issued,
this has become standard procedure for issuing toxic limits for facilities with IWC < 0.25%.

ACUTE TOXICITY TESTING REQUIREMENT (QRTRLY)
Fathead Minnow 24 hr.- No Significant Mortality
The permittee shall conduct acute toxicity tests on a guarterLv 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
in any two consecutive toxicity tests 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 performed after
thirty days from issuance of this permit during the months of f �1-2. 4' v , U t 9cJ .
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: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
•
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.
