BEFORE THE STATE OF FLORIDA DEPARTMENT OF ENVIRONMENTAL PROTECTION IN THE MATTER' OF:

Florida Power and Light, Inc. Administrative Order No. A0022TL 6501 S. Ocean Drive Jensen Beach, Florida 34957 St. Lucie Power Plant DEP Permit No: FL0002208 ADMINISTRATIVE ORDER I. STATUTORY AUTHORITY The Department of Environmental Protection (Department) issues this Administrative Order under the authority of Section 403.088(2)(f), Florida Statutes (F.S.). The Secretary of the Department has delegated this authority to the Director of the Division of Water Resources Management, who issues this order and makes the following findings of fact.

II. FINDINGS OF FACT I. Florida Power and Light (FPL or Permittee) is a "person" as defined under Section 403.031(5), F.S.

2. The Permittee owns and operates a nuclear steam electric power generating facility known as St.

Lucie power plant ("Facility"). The Facility, located at 6501 S. Ocean Drive, Jensen Beach St. Lucie County, Florida 34957, discharges industrial wastewater into waters of the state as defined in Section 403.03]1(13), F.S.

3. The Permittee has filed an application for revision of NPDES Permit No. FL0002208 (Permit), under Section 403.088(2), F.S.

4' The Permit expires on January 19, 2011. The Permittee has applied for renewal of the Permit 180 days before the expiration date. Hence, the Department may administratively continue the Permit, if necessary, after the expiration date of the Permit pursuant to Rules62-620.335(1)-(4), F.A.C.

5. The Permittee is planning to increase the generating capacity of its two existing nuclear units (Units I and 2) at the Facility by an additional 106 megawatts each. Known in the industry as a "power uprate," this effort entails modifying or replacing existing plant components such as the turbine generators, valves and certain control systems to increase electric generation capacity.
6. Units 1 and 2 use once-through cooling water from the Atlantic Ocean to remove heat from the main condensers via a circulating water system. The condensers are located in each unit's secondary system, where steam is cooled to liquid, water before being returned to the steam generators to complete the secondary loop. Cooling water is pumped from the Atlantic Ocean through three offshore intake structures into the plant's intake canal. This water is then pumped through the main condensers for each unit. Heated cooling water is released to the onsite discharge canal and then to open waters, as defined in Rule 62-302.520(3)(f, F.A.C., of the Atlantic Ocean through existing offshore pipes and diffusers.
7. After the power uprate is completed, the cooling water flow rate will remain unchanged; however, using thermodynamic models, the temperature in the discharge canal is predicted to increase by 2°F under normal operating conditions. The modeling effort indicates that the heated water released to

Administrative Order No. AO022TL FPL St. Lucie Power Plant NPDES Permit No. FL0002208 the Atlantic Ocean meets the surface temperature and adjacent coastal water requirements in Rule 62-302.520(4)(c), F.A.C., and the thermal mixing zone requirements in the existing Permit.

8. The Permittee anticipates commencing commercial operation of the repowered nuclear units sequentially in December 2011 (Unit 1) and July 2012 (Unit 2).
9. Rule 62-302.520(6)(a), F.A.C., authorizes the Department to establish mixing zones for thermal discharges from once-through cooling water systems, on a case-by-case bases, when supported by a demonstration, as provided in Section 316(a) of the Clean Water Act and regulations promulgated thereunder, including Title 40 of the Code of Federal Regulations (40 CFR) Parts 122 and 125, that assures the protection and propagation of a balanced, indigenous population of shellfish, fish and wildlife in and on the body of water.
10. Under 40 CFR Section 125.73, existing sources can base their 316(a) demonstration on a lack of appreciable harm instead of completing predictive studies. However, under 40 CFR Section 125.72(c), the type of detailed studies contemplated under 125.72(a) and (b) can be required whenever the Department determines it to be necessary. The Permittee collected a substantial amount of biological'data in support of its 316(a) demonstration from the mid 1970's to early 1980's. After examining the record of prior 316(a) determinations for the Facility after those dates, the Department has determined that a need exists for a more thorough examination of the balanced, indigenous population, the identification of representative important species, and a closer examination of whether the temperature limitations are protective.
11. Sections 403.088(2)(e) and (f), F.S., allow the Department to issue, renew, or reissue a permit for the discharge of wastewater into waters of the state, which may not immediately meet all applicable rule requirements, if the permit is accompanied by an order establishing a schedule for achieving compliance with all permit conditions if criteria specified in the order are met.
12. The Department finds that the granting of an operation permit will be in the public interest; and,
13. This order and associated wastewater Permit FL0002208 constitute the Department's authorization to discharge pollutants to waters of the state under the NPDES and its determination that the Facility is in compliance with Section 403.088, F.S. This order includes an implementation schedule.

-IM. ORDER Based on the foregoing findings of fact, IT IS ORDERED,

14. No later than 90 days after the effective date of this Order, the Permittee shall prepare and submit for the Department's review and approval a feasibility study report (Ambient Monitoring Report) for 1) the identification and evaluation of potential locations in the Atlantic Ocean that are near the Facility's ocean intake structure and meet the requirements of Rule 62-302.520(3)(a), F.A.C., for permanently sitingremote thermometers; and 2) the evaluation of commercially available remote thermometers. Each option, which shall consist of a location and a thermometer, shall be ranked based on equal weighting of technical and economic feasibility. The results of the ranking shall be presented in the Ambient Monitoring Report. In addition, the Ambient Monitoring Report shall include a plan and schedule for implementing the highest ranked option. The schedule shall include milestones and the completion date. The implementation shall take no longer than 18 months from the effective date of this Order.

Administrative Order No. AO022TL FPL St. Lucie Power Plant NPDES Permit No. FL0002208

15. No later than 30 days after installing the new thermometer(s), the Permittee shall provide a certification to the Department, signed and sealed by a licensed Professional Engineer, that the thermometer(s) have been properly installed and calibrated.
16. Until the Permittee has installed and calibrated new thermometer(s), for ambient temperature monitoring, the Permittee shall calculate the temperature rise above ambient at Outfall D-001 by subtracting the temperature measured at INT-1 from that measured at EFF-2. Monitoring locations INT-I and EFF-2 are defined in condition I.A.2 of Permit No. FL0002208.
17. No later than 180 days after the effective date of this Order, the Permittee shall prepare and submit for the Department's review and approval a plan of study (Heated Water POS) and schedule to confirm the results of the mathematical model used for simulating the near and far field extent of the Facility's heated water discharge. The Heated Water POS shall be designed and implemented to demonstrate that the heated water discharge from the Facility: 1) does not raise the surface temperature near the Facility's open ocean outfalls to more than 977F; and 2) does not heat adjacent coastal waters more than the limitations specified in Rule 62-302.520(4)(b), FAC. This study also shall evaluate whether and to what extent the heated water discharge raises the cooling water entering the Facility above ambient temperature. The study shall commence no later than 90 days after completion of both uprate projects for Unit I and 2. The study shall last no less than 24 months from commencement.

The results of the study shall be submitted in a report (Heated Water Report) to the Department for review and approval no later than 60 days after the approved Heated Water POS completion date.

The schedule shall include milestones and the completion date.

18. If the Heated Water Report fails to demonstrate that the heated water discharge from the Facility meets the discharge limitations in Part 11. 17 of this Order, the Permittee shall prepare a feasibility study report (Engineering Report) for the evaluation of engineering options to achieve the discharge limitations. The Engineering Report shall be submitted to the Department for review and approval no later than 180 days after after any Department determination that heated water from the discharge fails to meet the discharge limitations in Part 111. 17 of the Order. Tile options shall be ranked based on equal weighting of technical and economic feasibility. The results of the ranking shall be presented in the Engineering Report. In addition, the Engineering Report shall include a plan and schedule for implementing the highest ranked option. The schedule shall include milestones and the completion date. The implementation shall take no longer than 24 months from Department approval.
19. The Permittee shall provide a status report demonstrating progress toward compliance with the discharge limitation every six months following the approval of the Engineering Report, until compliance is achieved pursuant to Section I.A. of the Permit. The status reports shall document accomplishment of milestones established by the schedule in the approved Engineering Report.
20. No later than 90 days after the effective date of this Order, the Permittee shall prepare and submit for the Department's review and approval a biological plan of study (Biological POS) and schedule.

Biological POS shall be designed to generate information relevant to the following elements: 1) "a population typically characterized by diversity at all trophic levels;" 2) "the capacity to sustain itself through cyclic seasonal changes;" 3) "presence of necessary food chain species;" 4) "non-domination of pollution-tolerant species;" and 5) "indigenous." Each of these elements is discussed in more detail in Paragraphs I11. 21-25 of this Order. In addition to the foregoing elements, the Biological POS shall also include provisions for the identification of Representative Important Species (e.g., a list of threatened, endangered, thermally sensitive, or commercially or recreationally valuable species in up-and down-stream of the study area). Representative Important Species is defined as "species which are representative, in terms of their biological needs, of a balanced, indigenous community of shellfish, fish and wildlife in the body of water into which a discharge of heat is made." The study shall collect data pre- and post-completion of the uprate of Units 1 and 2 and shall last no less than 24 months after completion of the uprate. The results of the study shall be submitted in a report 3

Administrative Order No. AO022TL FPL St. Lucie Power Plant NPDES Permit No. FL0002208 (Biological Report) to the Department for review and approval no later than 90 days after the approved Biological POS completion date. The schedule shall include milestones and the completion date.

21. "A population typically characterized by diversity at all tropic levels" means that all of the major tropic levels present in the unaffected portion of the Atlantic Ocean should be present in the heat affected portions. The Department recognizes that community structure differences will occur, however, the number of species represented in each tropic level in the unaffected portions should be reasonably similar in the heat affected portions' of the ocean. Sampling and analysis of fish and invertebrate communities should be done such that the major tropic levels are identified and represented by reasonably similar species distributions. Also, the Biological POS shall be expanded to include some observations of wildlife (i.e., water fowl, mammals, amphibians, etc.) both upstream and immediately downstream of the discharge point that may be impacted by the thermal discharge.
22. "The capacity to sustain itself through cyclic seasonal changes" means that any additional thermal stress will not cause significant community instability during times of natural extremes in environmental conditions. Community data shall be collected during normal seasonal extremes as well as during optimal seasonal conditions. Data shall be compared between heat affected and unaffected portions of the ocean to account for normal community changes corresponding with change in season.
23. "Presence of necessary food chain species" means that the necessary food webs remain intact so that communities will be sustaining. Exhaustive food web studies are not necessary provided that planktonic invertebrate, fish and wildlife communities are otherwise healthy, i.e., represented by sufficiently high species diversity and abundance (appropriate for that portion of the ocean) for the identified tropic levels and sustaining through normal seasonal changes.
24. "Non-domination of pollution-tolerant species" means that in the case of a thermal effluent, community assemblages in heat affected portions of the ocean dominated by heat tolerant species do not constitute a balanced, indigenous population. The Department recognizes that because all species have varying levels of thermal tolerance, communities in the heat affected portions of the ocean may possess altered assemblages in terms of species present and abundance. All community data should be collected, analyzed and presented to clearly demonstrate that affected communities have not shifted to primarily heat tolerant assemblages.
25. "Indigenous" means a community that may include historically non-native species introduced in connection with a program of wildlife management and species whose presence or abundance results from substantial, irreversible environmental modifications. Normally, however, such a community will not include species whose presence is attributable to the introduction of pollutants that will be eliminated by compliance by all sources with Section 301 (b)(2) of the Clean Water Act, and may not include species whose presence or abundance is attributable to alternative effluent limitations imposed pursuant to a thermal zone of mixing. The Department recognizes that non-indigenous species are present in aquatic systems in Florida. All community data shall be analyzed and presented to demonstrate that community assemblages in the heat affected portions of the ocean are not significantly different from non-affected communities with regard to the number of non-indigenous species in the assemblages.
26. If the Biological Report fails to demonstrate that a balanced, indigenous population exists based on the criteria listed in Paragraphs 111, 16 of this Order, the Permittee shall prepare a feasibility study report (Report) for the evaluation of options to achieve a balanced, indigenous population. The Report shall be submitted to the Department for review and approval no later than 90 days after after any Department determination that heated water from the discharge fails to meet the discharge limitations in Part 111.20 of the Order. The options shall be ranked based on equal weighting of 4

Administrative Order No. AO022TL FPL St. Lucie Power Plant NPDES Permit No. FL0002208 technical and economic feasibility. The results of the ranking shall be presented in the Report. In addition, the Report shall include a plan and schedule for implementing the highest ranked option.

The schedule shall include milestones and the completion date. The implementation shall take no longer than 24 months from Department approval of the Report.

27. The Permittee shall provide a status report demonstrating progress toward a balanced, indigenous population every six months following the approval of the Report, until a balanced, indigenous population is achieved. The status reports shall document accomplishment of milestones established by the schedule in the approved Report.
28. Monitoring results shall be submitted in accordance with the Permit.

29, The Permittee shall maintain and operate its facilities in compliance with all other conditions of the Permit.

30. This Order may be modified through revisions as set forth in Chapter 62-620, F.A.C. Unless otherwise specified herein, reports or other information required by this order shall be sent to:

Industrial Wastewater Section, ATTN: Mail Station 3545, Department of Environmental Protection, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400, with a copies sent to: Industrial Wastewater Section, Department of Environmental Protection, Southeast District, 1801 SE Hillmoor Drive, Suite C-204, Port St. Lucie, Florida 34952 and Industrial Wastewater Section, Department of Environmental Protection, Southeast District, 400 N. Congress Avenue, Suite A,West Palm Beach, Florida 33416.

31. This order does not operate as a permit under Section 403.088, F.S. This order shall be incorporated by reference into NPDES Permit No. FL0002208, which shall require compliance by the Permittee with the requirements of this order.
32. Failure to comply with the requirements of this order shall constitute a violation of this order and Permit No. FL0002208, and may subject the Permittee to penalties as provided in Section 403.161, F.S.
33. This order is final when filed with the clerk of the Department, and the Perinittee then shall implement this order unless a petition for an administrative proceeding (hearing) is filed in accordance with the notice set forth in the following Section.
34. If any event occurs that causes delay or the reasonable likelihood of delay, in complying with the requirements of this order, the Permittee shall have the burden of demonstrating that the delay was or will be caused by circumstances beyond the reasonable control of the Permittee and could not have been or cannot be overcome by the Permittee's due diligence. Economic circumstances shall not be considered circumstances beyond the reasonable control of the Permittee, nor shall the failure of a contractor, subcontractor, materialman or other agent (collectively referred to as "contractor") to whom responsibility for performance is delegated to meet contractually imposed deadlines be a cause beyond the control of the Permittee, unless the cause of the contractor's late performance was also beyond the contractor's control. Delays in final agency action on an application for a relief mechanism are eligible for consideration under this paragraph, provided that none of those delays were a result of late submission by the Permittee. Upon occurrence of an event causing delay, or upon becoming aware of a potential for delay, the Permittee shall notify the Department orally at: the Department's Southeast District office, (772) 871-7662, within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or by the next working day and shall, within seven calendar days of oral notification to the Department, notify the Department in writing at: with a copies sent to: Industrial Wastewater Section, Department of Environmental Protection, Southeast District, 1801 SE Hillmoor Drive, Suite C-204, Port St. Lucie, Florida 34952 of the anticipated length and cause of the delay, the measures taken or to be taken to prevent or minimize the delay and the timetable by which Facility intends to implement these measures. If the 5

Administrative Order No. AO022TL FPL St. Lucie Power Plant NPDES Permit No. FL0002208 delay or anticipated delay has been or will be caused by circumstances beyond the reasonable control of the Permittee, the time for performance hereunder shall be extended for a period equal to the delay resulting from such circumstances.

IV. NOTICE OF RIGHTS A person whose substantial interests are affected by the Department's decision may petition for an administrative proceeding (hearing) under Sections 120.569 and 120.57 of the F.S. The petition must contain the information set forth below and must be filed (received by the clerk) in the Office of General Counsel of the Department at 3900 Commonwealth Boulevard, Mail Station 35, Tallahassee, Florida 32399-3000.

Petitions by the applicant or any of the parties listed below must be filed within twenty-one days of receipt of this written notice. Petitions filed by any persons other than those entitled to written notice under Section 120.60(3), F.S., must be filed within twenty-one days of publication of the notice or within twenty-one days of receipt of the written notice, whichever occurs first.

Under Section 120.60(3), F.S., however, any person who has asked the Department for notice of agency action may file a petition within twenty-one days of receipt of such notice, regardless of the date of publication.

The petitioner shall mail a copy of the petition to the applicant at the address indicated above at the time of filing. The failure of any person to file a petition within the appropriate time period shall constitute a waiver of that person's right to request an administrative determination (hearing) under Sections 120.569 and 120.57, F.S. Any subsequent intervention (in a proceeding initiated by another party) will be only at the discretion of the presiding officer upon the filing of a motion in compliance with Rule 28-106.205, F.A.C.

A petition that disputes the material facts on which the Department's action is based must contain the following information:

(a) The name, address, and telephone number of each petitioner; the Department permit identification number and the county in which the subject matter or activity is located; (b) A statement of how and when each petitioner received notice of the Department action; (c) A statement of how each petitioner's substantial interests are affected by the Department action; (d) A statement of the material facts disputed by the petitioner, if any; (e) A statement of facts that the petitioner contends warrant reversal or modification of the Department action; (f) A statement of which rules or statutes the petitioner contends require reversal or modification of the Department action; and (g) A statement of the relief sought by the petitioner, stating precisely the action that the petitioner wants the Department to take.

A petition that does not dispute the material facts on which the Department's action is based shall state that no such facts are in dispute and otherwise shall contain the same information as set forth above, as requiredby Rule 28-106.301, F.A.C.

Because the administrative hearing process is designed to formulate final agency action, the filing of a petition means that the Department's final action may be different from the position taken by it in this notice. Persons whose substantial interests will be affected by any such final decision of the Department have the right to petition to become a party to the proceeding, in accordance with the requirements set forth .above.

Mediation under Section 120.573, F.S., is not available for this proceeding.

This action is final and effective on the date filed with the Clerk of the Department unless a petition is filed in accordance with the above. Upon the timely filing of a petition this order will not be effective until further order of the Department.

Any party to the order has the right to seek judicial review of the order under Section 120.68, F.S., by the filing of a notice of appeal under rule 9.110 of the Florida Rules of Appellate Procedure with the Clerk 6

Sample Point Description of Monitoring Location EFF-I Outlet corresponding to the individual condenser from Unit I or Unit 2 EFF-2 Within the discharge canal upstream of the discharge piping to the Atlantic Ocean

3. At the peint of discharge monitoring location EFF-2,the heated water temperature from the diffsrs shall not exceed 113°F, before notification to the Department for power uprate completion for Units 1 and 2, orl57,F after notification to the Departmentforpower upratecompletion for Units ] and 2, or and 30'F above ambient at any time except that the maximum discharge temperature shall be limited to 117'F or and 321F above ambient during eondenser Er circulating water system maintenance, throttling circulatifng water pumps to minimize use of chlorine, or fouling of circulating water system. The ambient temperature may be measured at a point within the diseharge intake canal until installation of thermometer(s) in accordance with Administrative Order AOO22TL. In determining the temperature differential, the time of travel through the plant may be considered.. The permittee shall submit with the Discharge Monitoring Report a summary of cooling water system maintenance activities and associated maximum discharge temperature reading and temperature difference above ambient. In the event that discharge temperature exceeds 141-3F the temperaturelimitations, the Permittee shall notify the Department within 5 days.

Circulatingwater sstem maintenance (includinz but not limited to, condenser and! or circulating water pump maintenance)shall mean:

a. repairor scheduled preventive activities that maintain the facility 's circulatingwater system and its support systems within its as-designedcapacity, and
b. results in at least one circulatingwater pump being shut down, or equivalent loss of heat removal, on each unit being shut down.
4. Discharge from Outfall D-001 shall not cause the ocean surface temperature to exceed 97°F as an instantaneous maximum at any point. Heated water discharged from the multi-port diffuser shall not exceed 17 'F above ambient temperature in the receiving body of water outside a thermal mixing zone of 10.7 acre-feet (13,198 cubic meters, 466,092 cubic feet). The mixing zone shall be bounded by an area extending 1,385.5 feet seaward firomthe frost landward discharge port, 21.0 feet to each side of the discharge pipe axis and 8.0 feet in height above the bottom of the discharge. Heated water discharged from the Y-diffuser shall not exceed 170 F above ambient temperature in the receiving body of water outside a thermal mixing zone bounded by a circle with a radius of 115.82 meters, centered on the terminus of the Y-Port diffuser and extending upward from the bottom 8.31 meters, encompassing a mixing zone that shall not exceed 453,613 square feet (42,142 square meters). The total area of the thermal mixing zone for the facility (multi-port and Y-port diffusers) shall not exceed 511,804 square feet (47,548 square meters).
5. If automated TRO monitors are inoperable for more than 7 days, TRO monitoring shall be conducted at least one time per week on not less than three grab samples during daylight hours. Additional grab samples shall be obtained during periods of TRO discharge from condensers.
6. A "multiple grab" sample for FAO from Outfall D-001 for FAO/TRO monitoring shall consist of individual grab samples collected at the approximate beginning of FAO/TRO discharge and once every 15 minutes thereafter until the end of FAO/TRO discharge.
7. Free available oxidants (FAO) shall not exceed an average concentration of 0.2 mg/I and a maximum instantaneous concentration of 0.5 mg/I at the outlet corresponding to an individual condenser during any chlorination period. Additionally, TRO shall not exceed a maximum instantaneous concentration of 0.10 mg/I at any one time as measured at the POD prior to discharge to the Atlantic Ocean. Auxiliary equipment cooling water may receive continuous low-level chlorination. Neither FAO nor total residual oxidants (TRO) may be 4
