SPECIAL CONDITION FOR TERNIINATION OF MONSANTO DISCHARGE The Monsanto Roundup plant portion of this discharge is expected to terminate within the first half of 2002. The Monsanto Company will retain control over the utilities until such time as the facility and utilities are purchased. The allocation for this permitted discharge remains at 1.25 MGD. However, a new permit for the discharge will be issued when all of the following take place: • Proof of change of ownership from Monsanto Company has been furnished. The resulting name/ownership change form shall be submitted to the Division of Water Quality. • A new application for a discharge has been completed and submitted by the new owner of the facility with a request for a major modification of the NPDES permit. • The request for a major modification to NPDES Permit NC0003719 should include the appropriate fee for such an action. • Completion of the application shall include a complete flow justification for the proposed discharge and an Engineering Alternatives Analysis (EAA). When all of the above actions are complete, the Division shall furnish new effluent limits pages that are appropriate for the proposed discharge or set of discharges. A. (6.) BIOCIDE CONDITION The permittee shall not use any biocides except those approved in conjunction with the permit application. The permittee shall notify the Director in writing not later than ninety (90) days prior to instituting use of any additional biocide used in cooling systems which may be toxic to aquatic life other than those previously reported to the Division of Water Quality. Such notification shall include completion of Biocide Worksheet Form 101 and a map locating the discharge point and receiving stream. A. (7.) DETECTION LEVELS FOR COMPLIANCE If the discharge limitation of a given parameter is below quantitation limits, the measured quantity for the purposes of a compliance evaluation is considered to be zero. Values that report below quantitation level shall be deemed to be in compliance. Permit NC0003719 A. (8.) 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" (Revised -July, 1992 or subsequent versions). The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24 hour static test. The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure document). Effluent samples for self -monitoring purposes must be obtained during representative effluent discharge below all waste treatment. The tests will be performed during the months of February, May, August, and 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, DWQ Form AT-2 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Water r Quality 1621 Mail Service Center Raleigh, N.C. 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after the end of the reporting period for which the report is made. 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 there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the Permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited above. 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 the Permittee fail to monitor during a month in which toxicity monitoring is required, 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 Water Quality 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 follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring. 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 follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

Cutoff Concentration. For each parameter, the arithmetic mean of all analytical sampling results collected during the first year of the permit shall be calculated for each individual outfall and compared to the cut-off concentrations listed. If the arithmetic mean is below the specified cut-off concentration for a given parameter, then the facility is not required to continue annual analytical monitoring for that parameter at the outfall during the term of the permit unless a significant change in facility operations or configuration occurs. If cut-off concentration 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. 2. Measurement frequency. Once per year. The facility must perform analytical sampling during the first full year 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. Failure to monitor storm events in accordance with the specified frequency shall constitute a violation of this permit. 3. Sample Location. Samples to be collected at each stormwater discharge outfall (SW-1) located north of the river water intake pump overflow and south of the sludge drying beds. 4. For each sampled representative storm event the total precipitation, storm duration, and total flow must be monitored. Total flow shall be either: (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the amount of build -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute intervals during the rainfall event (not to exceed three hours). 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 Parts A. (13) and A. (14.)).

Failure to monitor storm events in accordance with the specified frequency shall constitute a violation of this permit. 3. Sample Location. Samples to be collected at each stormwater discharge outfall (SW-1) located north of the river water intake pump overflow and south of the sludge drying beds. 4. For each sampled representative storm event the total precipitation, storm duration, and total flow must be monitored. Total flow shall be either: (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the amount of build -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute intervals during the rainfall event (not to exceed three hours). 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 Parts A. (13) and A. (14.)) . Permit NC0003719 A (11). STORMWATER MONITORING REQUIREMENTS/ Qualitative Monitoring Qualitative monitoring requires a qualitative inspection of each stormwater outfall, regardless of representative outfall status, for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan and assessing new sources of stormwater pollution. No analytical tests are required. Qualitative monitoring of stormwater outfall does not need to be performed during a representative storm event.

Site Plan: The site plan shall provide a description of the physical facility and the potential pollutant sources which may be expected to contribute to contamination of regulated stormwater discharges. The site plan shall contain the following: (1) A general location map (USGS quadrangle map, or appropriately drafted equivalent map), showing the facility's location in relation to transportation routes and surface waters, and the name of the receiving water(s) to which the stormwater outfall(s) discharges. If the discharge is 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 must be shown. (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. (3) A site map (or series of maps) 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, 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 regulated stormwater discharge. (4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3 previous years and any corrective actions taken to mitigate spill impacts. (5) Certification that the stormwater outfalls have been evaluated for the presence of non- stormwater discharges. The certification statement will be signed in accordance with the requirements found in Part II, Section B.11. b. Stormwater Management Plan: The stormwater management plan shall contain a narrative description of the materials management practices employed which control or minimize the exposure of significant materials to stormwater, including structural and non-structural measures. The stormwater management plan, at a minimum, shall incorporate the following: (1) A study addressing the technical and economic feasibility of changing the methods of operations and/or storage practices to eliminate or reduce exposure of materials and processes to stormwater. Wherever practicable the permittee should consider covering storage areas, material handling operations, manufacturing or fueling operations to prevent materials exposure to stormwater. In areas where elimination of exposure is not practicable, the stormwater management plan shall document the feasibility of diverting the stormwater runoff away from areas of potential contamination. Permit NC0003719 (2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, or storage of hazardous materials to prevent leaks and spills from contaminating stormwater runoff. If the secondary containment devices are connected directly to stormwater conveyance systems, the connection shall be controlled by manually activated valves or other similar devices [which shall be secured with a locking mechanism] and any stormwater that accumulates in the containment area shall be at a minimum visually observed prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated. Records documenting the individual making the observation, the description of the accumulated stormwater and the date and time of the release shall be kept for a period of five years. (3) A narrative description of Best Management Practices (BMPs) to be considered such as, but not limited to, oil and grease separation, debris control, vegetative filter strips, infiltration and stormwater detention or retention, where necessary. The need for structural BMPs shall be based on the assessment of potential of sources contributing significant quantities of pollutants to stormwater discharges and data collected through monitoring of stormwater discharges. (4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit or prevent erosion associated with the stormwater systems. c. Spill Prevention and Response Plan: The Spill Prevention and Response Plan shall incorporate a risk assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel (or team) responsible for implementing the plan shall be identified in the plan. A responsible person shall be on -site at all times during facility operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. d. Preventative Maintenance and Good Housekeeping Program: A preventative maintenance program shall be developed. The program shall document schedules of inspections and maintenance activities of stormwater control systems, plant equipment and systems. Inspection of material handling areas and regular cleaning schedules of these areas shall be incorporated into the program. e. Training schedules shall be developed and training provided at a minimum on an annual basis on proper spill response and cleanup procedures and preventative maintenance activities for all personnel involved in any of the facility's operations that have the potential to contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the training shall be identified in the plan. f. The Stormwater Pollution Prevention Plan shall identify a specific position(s) responsible for the overall coordination, development, implementation, and revision to the Plan. Responsibilities for all components of the Plan shall be documented and position(s) assignments provided. Plan Amendment: The permittee shall amend the Plan whenever there is a change in design, construction, operation, or maintenance which has a significant effect on the potential for the discharge of pollutants via a point source to surface waters. The Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual basis. The director may notify the permittee when the Plan does not meet one or more of the minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit a time schedule to the Director for modifying the Plan to meet minimum requirements. The permittee shall provide certification in writing (in accordance with Part III, Standard Conditions, Section B.11.) to the Director that the changes have been made. g- Permit NC0003719 h. Facility Inspections: Inspections of the facility and all stormwater systems shall occur at a minimum on a semiannual schedule, once in the fall (September - November) and once during the spring (April - June). The inspection and any subsequent maintenance activities performed shall be documented, recording date and time of inspection, individual(s) making the inspection and a narrative description of the facility's stormwater control systems, plant equipment and systems. Records of these inspections shall be incorporated into the Stormwater Pollution Prevention Plan. Visual monitoring as required in A (4) Stormwater Monitoring Requirements/Qualitative 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. g- A.

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. GD/BSH/bsh Enclosure cc: FRO Files MAIL TO: AFFIDAVIT OF PUBLICATION NORTH CAROLINA, Cumberland County.

Box 2307, Cedar Creek Road; Fayetteville, North Carolina 28302 Facility Address: 3468 Cedar Creek Road; Fayetteville, North Carolina 28301 Permitted Flow 1.25 MGD Type of Waste: 91.3% industrial, 8.7% domestic Facility/Permit Status: Class III/Active; Renewal 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.

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.

Ms. Natalie Sierra Re: Draft Monsanto Fayetteville Site NPDES Permit #NC0003719 Dear Ms. Sierra, MONSANTO COMPANY AGRICULTURAL SECTOR P.O. BOX 2307 CEDAR CREEK ROAD FAYETEVILLE, NORTH CAROLINA 28302 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.
