This permit is issued under the provisions of Chapter 403, Florida Statutes, applicable rules of the Florida Administrative Code and constitutes authorization to discharge to waters of the State under the National Pollutant Discharge Elimination System. The above-nam ed permittee is hereby authorized to operate the facilities shown on the application and other documents attached hereto or on file with the Department and made a part hereof and specifically described as follows:

WASTEWATER TREATMENT AND EFFLUENT DISPOSAL: Cargill Fertilizer, Inc.’s South Fort Meade Mine operations include phosphate mining and beneficiation facilities, phosphatic clay settling areas, sand tailings disposal areas and a mine water recirculation system. The activities include the mining and washing of phosphate ore. The mined ore is slurried into a pit and pumped to the beneficiation plant where the fine clays and sand are separated from the phosphate rock (product) by washing, screening and double fl otation. The generated wet phosphate rock is transported to another location for further processi ng. The separated clays are pumped to settling areas (see TABLE 2 ). Sand tailings are pumped as a slurry to mined areas for use as reclamation fill or is stored above grade for later use in reclamation. The monitoring requirements for ground water discharges from sand tailings areas are also covered under this permit. On September 13, 2002, a request for modification of this permit was received for the cons truction and subsequent operation of a new 900-acre waste clay settling area designated as SFM-5. Constr uction will include approximately 22,300 linear feetof earthen containment dams with a minimum crest elevation of 165 feet NGVD. The north wall of SFM5 will be a common dam wall shared with the ex isting CSA SFM-3. Decanted water from the clay settling areas is returned to the beneficiation plan t for reuse and discharged, as necessary, through a 9.3- acre stilling basin to Outfall 001 (see TABLE 1 ) as authorized by this permit.CARGILL FERTILIZER, INC. Permit No. FL0037958 South Fort Meade Mine FDEP File No. FL0037958-007 Wastewater Permit Page 2 of 24

The current permit authorizes: 1) operation of a phosphate mine , beneficiation processing plant, product storage and shipping facilities, and three waste clay settling areas (CSAs) SFM-1, SFM-2, SFM-3 and SFM-4. 2) construction and subse quent operation, after receipt of Depa rtment approval per Part VII.B.4. below, of a CSA designated SFM-5. The proposed CSA SFM-5 will receive clay slurry vi a a pressurized pipeline into the southwest corner, and water will flow around an north-s outh trending diversion dike located in the approximate middle of the proposed settling area. An above grade return hy draulic ditch will be located along the east wall of the settling area and will be connected to the existing return hydraulic ditch system located immediately east of the project site. Three adjustable-weir decant spillway structures (located along the east wall of the settling area) will discharge clarified water into th e above grade return hydraulic ditch system. The water return ditch will bring decanted water back to th e beneficiation plant where it is then recycled or discharged (via the spillway basin and Outfall 001).A wash area for heavy earthmoving equipment (such as bulldozers and scrapers) has been constructed onsite. The wash facility generates approximately 250 GPM of wastewater and operates an average of two hours per day, five days per week. No cleaning agents or detergents are utilized at this facility. Instead, steam and high-pressure water are used. The source of the wash water is the plant reservoir. The effluent is pre-treated via an oil/water separator and a biologi cal reactor prior to discharge into the recirculation system. A sand tailings area is provided for reclamation pur poses. The return water ditch conducts treated wastewater from the clay settling areas and sand tailing st orage area to the plant reservoir for discharge or

reuse. This wastewater permit addresses the ground water permitting and monitoring requirements for this facility, pursuant to Florida Administrative Code Ru le 62-522. Monitoring of ground waters is included to determine any impacts caused by the clay settling areas or the sand tailings storage area.

NOTE: This permit replaces and supercedes in entirety all wastewater permits and modifications, which were previously issued by the Department’s Phosphate Management program for this facility.

IN ACCORDANCE WITH: The limitations, monitoring requirements and other conditions set forth in Part I, Part II, Part III, Part IV, Part V, Pa rt VI, Part VII and Part VIII of this permit.

2. In order to provide the Department with r easonable assurance that the discharge from Outfall 001 does not violate the acute toxicity requirements of Section 62-302.500(d), F.A.C., the permittee shall perform the toxicity tests as specified belo w and submit the results to the Department. The permittee shall initiate the series of tests descr ibed below, beginning in the first testing period following the effective date of this permit, to eval uate whole effluent toxicity of the discharge from Outfall 001. All test species, procedures, and qua lity assurance criteria used shall be in accordance with Methods for Measuring Acute Toxicity of Effluents to Freshwater and Marine Organisms

, EPA/600/4-90/027F, or the most current edition. Th e control water and dilution water used will be moderately hard water as described in EPA/600/4-90/027F, Table 6, or the most current edition. A standard reference toxicant (SRT) quality assurance (QA) acute toxicity test shall be conducted concurrently or no greater than 30 days before the date of the “routine” test, with each species used in the toxicity tests. The results of all toxicity tests shall be submitted with the discharge monitoring report (DMR). Any deviation of the bioassay pro cedures outlined herein shall be submitted in writing to the Department for review and approval prior to use. a. (1) The permittee shall conduct 96-hour acute sta tic renewal toxicity tests using the daphnid, Ceriodaphnia dubia , and the bannerfin shiner, Cyprinella leedsi . All tests will be conducted on single grab samples of 100% whole effluent and on a control. (2) If control mortality exceeds 10% for either species in any test, the test(s) for that species (including the control) shall be repeated. A test will be considered valid only if control mortality does not exceed 10% for either species. If, in any separate grab sample test, 100% mortality occurs prior to the end of the test, and control mortality is less than 10% at that time, that test (including the control) shall be terminated with the conclusion that the sample demonstrates unacceptable acute toxicity. b. (1) The toxicity tests specified above shall be conducted once during the months of December, January and February, and again during the months of July, August and Se ptember, but not to exceed two tests per year. Samples shall be collected only during actual discharge events. These tests are referred to as “routine” tests. The permittee shall monitor the toxicity, as described above, for the life of this permit. (2) All “routine” tests shall be conducted using a c ontrol (0% effluent) and a test concentration of 100% final effluent (3) Results from “routine” tests shall be reported according to EPA/600/4-90/027F, Section 12, Report Preparation (or the most current edition) , and shall be submitted to the address listed in Part I.B.3. c. (1) If unacceptable acute toxicity (greater than 20% mortality of either test species in any grab sample test) is found in a “routine” test, the permittee shall conduct three additional tests on each species indicating unacceptable toxicity. The first additional test will include four grab samples taken over a 24-hour period (6-hr intervals) and run as four separate definitive analyses. The second and third additional definitive tests will be run on a single grab sample collected on the day and time when the greatest t oxicity was identified in the first additional definitive test. Results for each additional test will include the determination of LC50 values with 95% confidence limits. (2) The first additional test shall be conducted using a control (0% effluent) and a minimum of five dilutions: 100%, 50%, 25%, 12.5% and 6.25% effluent. The dilution series may beCARGILL FERTILIZER, INC. Permit No. FL0037958 South Fort Meade Mine FDEP File No. FL0037958-007 Wastewater Permit Page 5 of 24

modified in the second and third test to more accura tely identify the toxicity, such that at least two dilutions above and two dilutions below the target toxicity and a control (0% effluent)

are run. (3) For each additional test, the sample collection requirements and the test acceptability criteria specified in Section 1 above must be met for the test to be considered valid. The first test shall begin within two weeks of the “routine” t ests, and shall be conducted weekly thereafter until three additional, valid tests are completed. The additional tests will be used to determine if the toxicity found in the “routine” test is still present. (4) Mortalities of greater than 50% in 100% effl uent or an LC50 of less than 100% effluent in any additional definitive test will constitute a violation of these permit conditions, and Rule 62-302.200(1), Rule 62-302.500(1)(d), and Rule 62-4.244(3)(a), F. A. C. (5) Results from additional tests, required due to unacceptable acute toxicity in the “routine” tests, shall be submitted in a single report prepared according to EPA/600/4-90/027F, Section 12, or the most current edition and submitted with in 45 days of completion of the additional, valid tests. Upon completion of the third additional test, the permittee will schedule to meet with the Department within 30 days of the report submittal to identify the cause(s) and corrective actions (if applicable) necessary to remedy the unacceptable acute toxicity. (6) If acute toxicity is found, chronic toxicity testing may be required.

3. The reported nutrient loading for Nitrogen and Phos phorus in Part I.A.1. above are to be calculated using the daily flow recorded for the day on which the sample is taken.

4. The discharge of nutrients shall be limited in accordance with Rule 62.302.530(48) a. and b, F.A.C.

5. Specific Conductance shall not be increased more than 50% above backgr ound or to 1275 umhos/cm, whichever is greater.

6. The permittee shall ensure that the water quality standards for Class III surface waters as defined in Sections 62-302.500, 62-302.510 and 62-302.530, F.A.C., ar e not violated at the points of discharge.

7. There shall be no discharge of floating solids or visible foam in other than trace amounts.

8. The discharge shall not cause a visible sheen on the receiving water.

9. Until a Total Maximum Daily Load (TMDL) for total nitrogen is determined for this facility and this permit modified pursuant to Florida Administrative Code Rules 62-4.080 and 62-620.325, the permittee shall strive to achieve the target valu es (concentration and/or loading goals) for total nitrogen (as N), from Outfall 001 as listed in Part I.A. 1. If a total nitrogen target value (concentration or load) is exceeded for any outfall authorized by this permit, the permittee shall notify the Department and within 7 days submit a written e xplanation for the exceedance. The permittee shall also describe all pollution prevention projects, im plementation of BMPs, etc. and what follow-up action is necessary, if any, to provide reasona ble assurance that the requirements of Florida Administrative Code Rule 62-302.530(48) [Nutrients] will be met.

References to be considered in developing the plan are "Criteria and Standards for Best Management Practices Authorized Under Section 304(e) of the Act," found at 40 CFR 125, Subpart K and the Waste Minimization Opportunity Assessment Manual, EPA/625/7-88/003.

a. Definitions (1) The term "pollutants" refers to conven tional, non-conventional and toxic pollutants. (2) Conventional pollutants are: biochemical oxy gen demand (BOD), suspended solids, pH, fecal coliform bacteria and oil & grease. (3) Non-conventional pollutants are those whic h are not defined as conventional or toxic. (4) Toxic pollutants include, but are not limited to: (a) any toxic substance listed in Section 307(a)(1) of the CWA, any hazardous substance listed in Section 311 of the CWA, or chemical listed in Section 313(c) of the Supe rfund Amendments and Reauthorization Act of 1986; and (b) any substance (that is not also a conventional or non-conventional pollutant except ammonia) for which EPA has published an acute or chronic toxicity criterion. (5) "Pollution prevention" and "waste minimization" refer to the first two categories of EPA's preferred hazardous waste management strategy: first, source reduction and then, recycling. (6) "Recycle/Reuse" is defined as the minimi zation of waste generation by recovering and reprocessing usable products that might otherwi se become waste; or the reuse or reprocessing of usable waste products in place of the original stock, or for other purposes such as material recovery, material regenera tion or energy production. (7) "Source reduction" means any practice whic h: (a) reduces the amount of any pollutant entering a waste stream or otherwise released into the environment (including fugitive emissions) prior to recycling, treatment or disposal; and (b) reduces the hazards to public health and the environment associated with the release of such pollutant. The term includes equipment or technology modifications, process or procedure modifications, reformulation or redesign of products, substitution of raw materials, and improvements in housekeeping, maintenance, training, or inventory control. It does not include any practice which alters the physical, chemical, or biological characteristics or the volume of a pollutant through a process or activity which itself is not integral to, or previously considered necessary for, the production of a product or the providing of a service. (8) "BMP3" means a Best Management Plan incorporating the requirements of 40 CFR § 125, Subpart K, plus pollution prevention techniques associated with a Waste Minimization Assessment. (9) "Waste Minimization Assessment" means a syst ematic planned procedure with the objective of identifying ways to reduce or eliminate waste. 2. Best Management Practices/Pollution Prevention Plan The permittee shall develop and implement a BMP3 plan for the facility which is the source of wastewater and storm water discharges covered by th is permit. The plan shall be directed toward reducing those pollutants of concern which discharge to surface waters and shall be prepared in accordance with good engineering and good housekeeping practices. For the purposes of this permit, pollutants of concern shall be limited to toxic pollu tants, as defined above, known to the discharger. The plan shall address all activities which could or do contribute these pollutants to the surface water discharge, including process, treatment, and ancillary activities.CARGILL FERTILIZER, INC.
