NPDES STAFF REPORT AND RECOMMENDATIONS
County Cumberland
NPDES Permit No. NC0003719
PART I. GENERAL INFORMATION
1. Facility and Address: Monsanto Agricultural Company
A Unit of Monsanto Company
P.O. BOX 2307
Fayetteville, North Carolina 28302
2. Date of Investigation: April 2, 1992
3. Report Prepared By: Grady Dobson, Environmental Engineer, Fayetteville
Regional Office
4. Persons Contacted and Telephone Number: H. Van Bell, Plant Manager
[phone]
5. Directions to Site: From Fayetteville travel NC53 East. The Plant is
located 8 miles from the Fayetteville
6. Discharge Point(s), List for all discharge points:
Latitude:340 58' 8" Longitude: 780 46' 58"
Attach a USGS map extract and indicate treatment facility site and
discharge point on map.
USGS Quad No. H23 NE USGS Quad Name Cedar Creek , N C
7. Size (land available for expansion and upgrading): 273 acres

8. Topography (relationship to flood plain included): Relatively Flat
9. Location of nearest dwelling: None within 500 feet
10. Receiving stream or affected surface waters:Cape Fear River
a. Classification: Class C
b. River Basin and Subbasin No.: Cape Fear 03-06-15
c. Describe receiving stream features and pertinent downstream uses:
Aquatic life propagation and survival, fishing, wildlife, secondary
recreation, and agriculture
PART II - DESCRIPTION OF DISCHARGE AND TREATI! NT WORKS
1. Type of wastewater: 1 % Domestic
99 % Industrial
a. Volume of Wastewater: 2.3 MGD (Design Capacity)
b. Types and quantities of industrial wastewater:
c. Prevalent toxic constituents in wastewater: N/A
d. Pretreatment Program (POTWs only): N/A
in development approved
should be required not needed N A
2. Production rates (industrial discharges only) in pounds per day:
a. Highest month in the past 12 months: July 1991, 1.3 million lbs
b. Highest year in the past 5 years: 1989, 21.5 million lbs
3. Description of industrial process (for industries only) and applicable
CFR Part and Subpart: 40 CFR 414.91
4. Type of treatment (): The existing wastewater treatment process flows
as follows: Process water enters a lift station and is pumped to a 1
million gallon spill basin. Wastewater then passes through an oil
skimmer and into a four (4) million gallon equalization basin. After ph
adjustment the process waste stream enters a 0.4 MG aeration basin and a
1MG aeration basin operated in parallel. Following this is a 50 diameter
clarifier, a 90 foot clarifier, filters (SBR), chlorine contact chamber,
aerobic sludge digester, sludge storage basin, and sludge drying
beds.Contributions to this treatment unit comes from FII & ICI which
both produce polyester resins and fibers, and Monsanto which
manufactures an agricultural herbicide (ROUNDUP).

5. Sludge handling and disposal scheme: Permitted land Application Facility
(Permit No. WQ0001959)
6. Treatment plant classification (attach completed rating sheet):See
attached rating sheet (Grade III)
7. SIC Code(s): Monsanto (2879) ICI (2821) FII (2299)
Wastewater Code(s):Primary 02` Secondary _
Main Treatment Unit Code: 05001
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grants Funds
(municipals only)? N/A
2. Special monitoring requests: N/A
3. Additional effluent limits requests: N/A
4. Other: Monsanto requests the removal of outfall #001 monitoring
requirements.This outfall contains the noncontact blowdown streams --
Cooling Tower Blowdown, Demineralized Water Treatment Blowdown, Boiler
Blowdown,and Backwash Pond Blow down. Monsanto proposes to eliminate
this discharge point(#001) and route the above through biological
treatment system & discharge through discharge point #002. Discharge
#003 (Incineration Scrubber Unit ) will remain unchanged.

PART IV - EVALUATION AND RECOMMENDATION
It is the recommendation of this office that the subject application be
processed and the appropriate permit issued.
