Marchigiano Station Manager Crystal River Units 1 & 2 15760 Power Line Street, POC Crystal River, FL 34428 FACILITY:

Crystal River Units 1, 2 and 3; and Citrus Combined Cycle Units PB-i & PB-2 15760 Power Line Street Crystal River, FL 34428 Citrus County Latitude: 250 57' 27" N Longitude: 820 41' 58" W This permit is issued under the provisions of Chapter 403, Florida Statutes (F.S.) and applicable rules of the Florida Administrative Code (F.A.C.), and constitutes authorization to discharge to waters of the state under the National Pollutant Discharge Elimination System. Compliance with Administrative Order AO024TL is a specific requirement of this permit.

This permit does not constitute authorization to discharge wastewater other than as expressly stated in this permit. The above named permittee is hereby authorized to operate the facilities in accordance with the documents attached hereto and specifically described as follows:

FACILITY DESCRIPTION:

The Crystal River Energy Complex (CREC) is an electric generating plant located on an approximately 4,729 acre site near the mouth of Crystal River. The CREC consists of five steam electric generating units (Units 1, 2, 3, 4 and 5) with a total nameplate rating of 3,333.1 megawatts (MW~). The surface water discharges from Units 4 and 5 are regulated under a separate wastewater permit (NPDES Permit No. FL00363 66). Operation of an industrial wastewater treatment and disposal system to serve the facility is regulated under the Florida Electrical Power Plant Siting Act (License No. PA77-09). Units 1 and 2 are pulverized coal-fired steam electric generating units and Unit 3 is a nuclear fueled electric generating unit.

However, Unit 3 has been shut down since September 2009, and the permittee announced on February 5, 2013 that the unit has been permanently retired. Units 1 and 2 have a combined total name plate rating of approximately 964 MW. The facility discharge consists of once-through, non-contact condenser cooling water, treated nuclear auxiliary cooling water, treated coal pile rainfall run off, intake screen wash water, and treated non-radioactive wastewater/radiation wastewater.

The radioactive component of the discharge is regulated by the U.S. Nuclear Regulatory Commission under Atomic Energy Act and not by the U.S. Environmental Protection Agency under the Clean Water Act.

Duke Energyv Floridaplans to construct and operate a nominal 1,640-Mw natural gas-fired. combined cycle combustion turbine generator(CTG) facility, identified as the Citrus Combined Cycle (CCC) Project, on a 400-acre site immediately adjacent to the existing CREC. This facility will consist of two power blocks (PB-i and PB-2). each consistingof two natural gas-fired combustion turbines and a single steam turbine. Each power block will be capable of generating 820 MWK The power blocks are anticipatedto begin commercial operations in June 2018 and December 2018. respectively. Upon the CCC facility becominz operational, the permittee will begin the retirement of Units 1 and 2.

WASTEWATER TREATMENT:

Units 1 and 2 use once-through, noncontact cooling water (OTCW) withdrawn from and returned to Crystal Bay via the main intake and discharge canal at the facility. With the announced retirement of Unit 3 on February 5, 2013, this unit no longer discharges OTCW from outfall D-0 13. Unit 3 has not discharged OTCW since September 2009. This permit authorizes an 1

PERMITTEE: Duke Energy Florida, Inc. PERMIT NUMBER: FL0000 159 (Major)(Rev..._. B)

FACILITY: Crystal River Units 1, 2 and 3 EXPIRATION DATE: April 6, 2019 on-line mechanical condenser cleaning system, as well as use of oxidizing biocides, however, current practice is to remove Units 1 and 2 condensers out of service for manual cleaning.

Even with the announced retirement of Unit 3, th*e Nuclear Scr,'iees and Decay Heat Seawater Sysztem, Station Drain Tank-i (SDT-1) system (non-radwaste treatment system), Evaporator Condensate Storage Tanks (ECST) system (radwaste treatment system) and Laundry Shower and Sump Tanks (LSST) system will remain in operation during the upcoming permit cycle due to the continued operation of the spent fuel p301 and e~ther ancillary processes. The process wastewaters generated by these systems will continue to be discharged from Outfall D-00F.

The SDT-1 system uses oil-water separation to control oil and grease as well as mixing to aid in buffering pH. The treated wastewater is discharged by batch releases through internal outfall I-FG to outfall D-00F; or alternatively to the on-site industrial wastewater percolation pond under License No. PA 77-09P. The waste streams treated in this system include the following low volume wastes: turbine building sumps, equipment drains and floor drains; laboratory wastes from system evaluation; water supply and intermediate cooling system laboratory waste; water leakage from auxiliary plant systems; wastewater from hydrolasing activities; and miscellaneous secondary-side system drainage.

The ECST system uses an ion exchange system for pollution control. Spent resins are sluiced to a spent resin storage tank along with other spent resins (e.g., those used to polish water used for the spent fuel pool), whereby they are then disposed off-site. The treated sluice water is then discharged by batch releases through outfall D-00F.

The ECST system also includes a waste storage tank that receives low volume wastes from a number of sources consisting mostly of sump and floor drains within the reactor and auxiliary buildings. Note, these wastewaters are required to be monitored and meet limits for several radionuelides in accordance with the U.S. Nuclear Regulatory Commission under Atomic Energy Act and not by the U.S. Environmental Protection Agency under the Clean Water Act.

The LSST system consists of cartridge and bag filters to control total suspended solids. The treated wastewater is discharged by batch releases through internal outfall I-FE to outfall D-00F. The waste streams treated in this system include the following low volume wastes: laundry wash water; mop water; floor drain wastewater; laboratory wastewater from the primary, regent, and annex laboratories; leakage from auxiliary plant systems; and wastewater from hydrolasing activities.

Mechanical draft helper cooling towers (HCTs), located adjacent to site discharge canal, withdraw water directly from the main discharge canal to provide additional cooling. The noncontact, once-through cooling water is then returned to the discharge canal through Outfalls D-071land D-072. In addition, the HCTs are authorized to inject an oxidizing biocide to control biofouling.

Outfalls D-091, D-092, D-093 and D-094 are discharges produced when water from the intake canal (for outfalls D-091, D-092 and D-093) and discharge canal (outfall D-094) is used to wash debris from the rotating traveling screens protecting the intake pumps at Units 1 and 2; the raw water pumps at Unit 3; and also the HCTs.

Runoff from the south coal pile storage area is captured in a collection ditch and pond system. This system has a single valved outfall. This outfall discharges to a marshy area south of the coal pile storage area. The valve is kept in the closed position, and only opened manually during emergency conditions to protect the berm integrity. Discharge may also be accomplished with the use of pumps during emergency conditions.

As per U.S. Nuclear Regulatory Commission directive, Unit 3 is required to maintain a backup, independently-powered, portable water supply pump to provide an emergency source of water for various activities such as firefighting, containment spray, flooding the spent fuel pool, etc. The directive also mandates that the pump be tested periodically. During testing events, which are required every two months, the pump is operated for approximately 30 minutes at 300 gpm producing a discharge of approximately 9,000 gallons of service water (treated groundwater), with an annual test using intake canal water (seawater). Water is discharged into the intake canal near the Unit 3 intake structure.

The permittee shall comply with the BMP3 requirements below and schedule in Condition VI.1 if the developed SWPPP is not implemented.

1.General Conditions In accordance with Section 304(e) and 402(a)(2) of the Clean Water Act (CWA) as amended, 33 U.S.C. §§ 1251 et seq., and the Pollution Prevention Act of 1990, 42 U.S.C. §§ 13101-13109, the permittee must develop and implement a plan for utilizing practices incorporating pollution prevention measures. 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 122.44 Subpart K and the Storm Water Management Industrial Activities Guidance Manual, EPA/833-R92-002 and other EPA documents relating to Best Management Practice guidance.

a. Definitions (1) The term "pollutants" refers to conventional, non-conventional and toxic pollutants.

(2) Conventional pollutants are: biochemical oxygen demand (BOD), suspended solids, pH, fecal coliform bacteria and oil & grease.

(3) Non-conventional pollutants are those which 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 Superfund 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) "Significant Materials" is defined as raw materials; fuels; materials such as solvents and detergents; hazardous substances designated under Section 10 1(14) of CERCLA; and any chemical the facility is*

required to report pursuant to EPCRA, Section 313; fertilizers; pesticides; and waste products such as ashes, slag and sludge.

(6) "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.

(7) "Recycle/Reuse" is defined as the minimization of waste generation by recovering and reprocessing usable products that might otherwise 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 regeneration or energy production.

(8) "Source reduction" means any practice which: (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.

(9) "BMP3" means a Best Management Practices Pollution Prevention Plan incorporating the requirements of 40 CFR § 125, Subpart K, plus pollution prevention techniques, except where other existing programs are deemed equivalent by the permittee. The permittee shall certify the equivalency of the other referenced programs.

(10) The term "material" refers to chemicals or chemical products used in any plant operation (i.e., caustic soda, hydrazine, degreasing agents, paint solvents, etc.). It does not include lumber, boxes, packing materials, etc.

INSTRUCTIONS FOR COMPLETING THlE WASTEWATER DISCHARGE MONITORING REPORT Read these instructions before completing the DMR. 1Hard copies and/or electronic copies of the required parts of the DMR were provided with the penmit. All required information shall be completed in full and typed or printed in ink. A signed, original DMR shall be mailed to the address printed on the DMR by the 2 8d, of the month following the monitoring period. The DMR shall not be submitted before the end of the monitoring period.

The DMR consists of three parts--A, B, and 0--all of which may or may not be applicable to every facility. Facilities may have one or more Part A's for reporting effluent or reclaimed water data. All domestic wastewater facilities will have a Part B for reporting daily sample results. Part D is used for reporting ground water monitoring well data.

When results are not available, the following codes should be used on parts A and 0 of the DMR and an explanation provided where appropriate. Note: Codes used on Part B for raw data are different.

CODE DESCRIPTION/INSTRUCTIONS CODE DESCRIPTION/INSTRUCTIONS ANC Analysis not conducted. NOD No discharge from/to site.

DRY Dry Well OPS Operations were shutdown so no sample could be taken.

FLD Flood disaster. 0TH Other. Please enter an explanation of why monitoring data were not available.

IFS Insufficient flow for sampling. SEF Sampling equipment failure.

LS Lost sample.

MNR Monitoring not required this period.

When reporting analytical results that fall below a laboratory's reported method detection limits or practical quantification limits, the following instructions should be used:

I. Results greater than or equal to the PQL shall be reported as the measured quantity.

2. Results less than the PQL and greater than or equal to the MDL shall be reported as the lahoratomy,'s MDL value. These values shall be deemed equal to the MDL when necessary to calculate an average for that paramneter and when determining compliance with permit limits.

3. Results less than the MDL shall be reported by entering a less than sign ("<") followed by the laboratory's MDL value, e.g. < 0.001I. A value of one-half the MDL or one-half the effluent limit, whichever is lower, shall be used for that sample when necessary to calculate an average for that parameter. Values less than the MDL are considered to demonstrate compliance with an effluent limitation.

PART A -DISCHARGE MONITORING REPORT (DMR)

Part A of the DMR is comprised of one or more sections, each having its own header infonmation. Facility infonmation is preprinted in the header as well as the monitoring group number, whether the limits and monitoring requirements are interim or final, and the required submittal frequency (e.g. monthly, annually, quarterly, etc.). Submit Part A based on thle required reporting frequency in the header and the instructions shown in the permit. The following should be completed by the permittee or authorized representative:

Resubmitted DMR: Check this box if this DMR is being re-submitted because there was infonnation missing fromn or information that needed correction on a previously submitted DMR. The infonnation that is being revised should be clearly noted on the re-submitted DMR (e.g. highlight, circle, etc.)

No Discharge From Site: Check this box if no discharge occurs and, as a result, there are no data or codes to be entered for all of the parameters on the DMR for tile entire monitoring group number; however, if the monitoring group includes other monitoring locations (e.g., influent samnpling), the "NOD" code should be used to individually denote those parameters for which there was no discharge.

Monitoring Period: Enter the month, day, and year for the first and last day of the monitoring period (i.e. the month, the quarter, the year, etc.) during which the data on this report were collected and analyzed.

Sample Measurement: Before filling in sample measurements in the table, check to see that the data collected correspond to the limit indicated on the DMR (i.e. interim or final) and that the data correspond to the monitoring group number in the header. Enter the data or calculated results for each parameter on this row in the non-shaded area above the limit. Be sure the result being entered corresponds to the appropriate statistical base code (e.g. annual average, monthly average, single samnple mnaxhnum, etc.) and units.

No. Ex.: Enter the number of sample measurements during the monitoring period that exceeded the permit limit for each parameter in the non-shaded area. If none, enter zero.

Frequency of Analysis: The shaded areas in this columnn contain the minimumn numnber of tisnes the measurement is required to be made according to the permit. Enter the actual number of times the measurement was mnade in the space above the shaded area.

Sample Type: The shaded areas in this column contain the type of sample (e.g. grab, composite, continuous) required by the pennit. Enter the actual sample type that was taken in the space above the shaded area.

Signature: This report must be signed in accordance with Rule 62-620.305, F.A.C. Type or print the name and title of the signing official. Include the telephone number where the official mnay be reached in the event there are questions concemning this report. Enter the date when the report is signed.

Comment and Explanation of Any Violations: Use this area to explain any exceedances, any upset or by-pass events, or other itemns which require explanation. If more space is needed, reference all attactmnents in this area.

PART B - DAILY SAMPLE RESULTS Monitoring Period: Enter the month, day, and year for the first and last day of the monitoring period (i.e. the month, thle quarter, the year, etc.) during which the data on this report were collected and analyzed.

Daily Monitoring Results: Trsnsfer all analytical data from your facility's laboratory or a contract laboratory's data sheets for all day(s) that samples were collected. Record the data in the units indicated. Table 1 in Chapter 62-160, F.A.C., contains a complete list of all the data qualifier codes that your laboratory may use when reporting analytical results. H-owever, when transferring numerical results onto Part B of the DMR, only the following data qualifier codes should he used and an explanation provided where appropriate.

CODE DESCRIPTION/INSTRUCTIONS

< The compound was analyzed for but not detected.

A Value reported is the mean (average) of two or more determinations.

J Estimaated value, value not accurate.

Q Sample held beyond the actual holding time.

Y Laboratory analysis was from an unpreserved or improperly preserved sample.

To calculate the monthly average, add each reported value to get a total. For flow, divide this total by the number of days in the month. For all other parameters, divide the total by the number of observations.
