1.0 INTRODUCTION
The St. Lucie Nuclear Power Plant (St. Lucie Plant) [Industrial Wastewater Facility (IWWF) Permit No.
FL 0002208] is located on a 1,132-acre site on Hutchinson Island in St. Lucie County, Florida. The plant consists of two nuclear-fueled electric-generating units.
Unit 1 received an operating license in March 1976 and Unit 2 in April 1983. The St. Lucie Plant is located on the widest section of Hutchinson Island.
The island is separated from the mainland on its western side by the Indian River Lagoon (IRL) and borders the Atlantic Ocean on the east (see Figure 1).
The source of once-through cooling water for the St. Lucie Plant is the Atlantic Ocean. At the location of the St. Lucie Plant on Hutchinson Island, the edge of the continental shelf extends approximately 21 miles offshore. Hutchinson Island is a barrier island that extends 22.5 miles between inlets (Ft. Pierce and St. Lucie Inlets) and attains a maximum width of 1.2 miles at the St. Lucie Plant site. Near shore, in the vicinity of the St. Lucie Plant, mean water depths typically range from 23 to 32 feet (ft) [National Oceanic and Atmospheric Administration (NOAA) Chart, 11472].
There is an offshore shoal, Pierce Shoal, approximately 2 to 3 miles offshore.
The St. Lucie Plant discharges its once-through cooling water back to open waters of the Atlantic Ocean via two discharge pipes. One discharge pipe is outfitted with a Y-port diffuser and the second with a multi-port diffuser.
The St. Lucie Plant is undergoing an extended power uprate (EPU) to increase its net electrical power generation by approximately 100 MW per unit. To accommodate the approximately 20 F increase in the discharge temperature that is projected to be associated with the EPU, a permit revision application was submitted by Florida Power & Light Company (FPL) to the Florida Department of Environmental Protection (FDEP) to change the St. Lucie Station's heated water discharge limitations in the IWWF permit.
On December 23, 2010, this request was approved by the FDEP contingent upon the implementation of additional monitoring requirements.
In conjunction with its approval of the facility's IWWF permit, the FDEP issued Administrative Order AO022TL. Condition 17 of this Administrative Order set forth field monitoring requirements to confirm the results of the heated water discharge plume modeling previously submitted by FPL:
Condition 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 97 0F; and 2) does not heat adjacent coastal waters more than the limitations specified in Rule 62-302.520(4)(b), F.A.C. This study also shall evaluate whether and to what extent the heated water discharge raises the temperature of the cooling water entering the Facility above ambient temperature. The
'ý_Associates
June 2011 2
103-87735 study shall commence within 90 days after completion of both uprate projects for Unit 1 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.
Rule 62-302.520(4)(b), Florida Administrative Code (F.A.C.) states "Heated water with a temperature at the Point of Discharge (POD) more than 20 F higher than ambient (natural) temperature of the Receiving Body of Water (RBW) shall not be discharged into coastal waters in any zone during the months of June, July, August, and September. During the remainder of the year, heated water with a temperature at the POD more than 40 F higher than ambient (natural) temperature of the RBW shall not be discharged into coastal waters in any zone. In addition, during June, July, August, and September, no heated water with a temperature above 920 F shall be discharged into coastal waters.
Further no heated water with a temperature above 90' F shall be discharged into coastal waters during the period October thru May."
Coastal waters, as defined in Rule 62-302.520(3), in the Atlantic Ocean in the vicinity of the St. Lucie Plant include all waters shoreward of the 18-depth contour as shown on Coast and Geodetic Survey Charts. All waters seaward of this contour, as defined in Rule 62-302.520(3), are open waters.
Rule 62-302.520(4)(c), F.A.C., states that for open waters "the surface temperature of the RBW shall not be raised to more than 970 F and the POD must be sufficient distance offshore to ensure that the adjacent coastal waters are not heated beyond the temperatures permitted in such waters."
In addition, Condition 14 of Administrative Order AO022TL required the completion of a feasibility study Ambient Monitoring Report (AMR) for installing permanent remote thermometers to monitor ambient temperatures.
The purpose of the AMR was to determine the appropriate ambient Atlantic Ocean temperature to be used for mixing zone/thermal impact modeling. Since that time, FPL proposed that the determination of an appropriate ambient temperature could be satisfied as part of the HWPOS. The results of the HWPOS will determine whether or not a permanent remote ambient temperature monitoring station will need to be sited in the Atlantic Ocean.

103-87735 2.0 PROJECT OBJECTIVES The objective of the Heated Water Plan of Study (HWPOS) is to develop data to confirm the predictions of the mathematical thermal model for simulating the near-field and far-field extent of the St. Lucie Plant's heated water plume in the Atlantic Ocean. The HWPOS includes three components:
Demonstrate that the discharge of cooling water from the St. Lucie Plant does not raise surface water temperatures in the vicinity of the open ocean outfalls to more than 97 degrees Fahrenheit (°F).
Demonstrate that the open ocean cooling water outfalls do not heat adjacent coastal waters above the limitations specified in 62-302.520(4)(b), F.A.C.
Evaluate whether, and to what extent, the St. Lucie Plant's cooling water discharge raises the temperature of the cooling water being drawn into the St. Lucie Plant above ambient temperature.
To achieve these objectives, heated water temperature monitoring stations will be established (or existing stations utilized) at several locations:
Near the St. Lucie Plant open ocean discharge outfalls, At the 18-ft contour, and In the vicinity of the St. Lucie Plant intake structures as well as the intake and discharge canals.
An ambient (background) temperature monitoring station and two velocity profiling stations will also be included in the study.
The proposed location of these stations is shown in Figure 2. The following subsections summarize the thermal modeling output information considered in the selection of station locations.
2.1 Surface Water Temperature Near the Discharge Structures The first requirement of Condition 17 is to confirm that the surface temperature in the vicinity of the discharges is not raised above 970 F. Since "surface temperature" is not defined in 62-302.520, F.A.C.,
for the purposes of this study it is taken to be the uppermost 2 ft of the water column.
Surface temperature measurements will be collected at a depth between 1 ft and 2 ft below the surface. Modeling results indicate that peak surface temperatures occur within 100 to 200 ft of the discharge from the Y-port diffuser.
For the multi-port diffuser, maximum surface temperatures occur within 0 to 50 ft of the discharge pipe.
2.2 Coastal Waters The second requirement of Condition 17 is to verify that coastal waters (shoreward of the 18-ft depth contour) are not heated beyond the limitations of Rule 62-302.520(4)(b), F.A.C. These regulations allow for a maximum coastal temperature increase of 2°F above ambient during summer months (June to Goider Associates
June 2011 4
103-87735 September) and 4°F above ambient for the remainder of the year. Three monitoring stations are proposed to meet this requirement.
The first station will be located between the discharge pipes at the 18-ft contour. This is the closest point in coastal waters to the source of heated water. Two other stations will be located between 0.5 mile and 1.0 mile north and south along the 18-ft contour, at locations where the modeling results suggest the greatest possibility of heated water incursion into coastal waters.
This study is also designed to provide a comparison to the ambient temperature of the coastal waters. To make this comparison the HWPOS proposes to take advantage of the buoyant properties of the discharge plume. Warmer water is less dense than cooler water and therefore, if present, the plume would be expected to be found at the surface. At each station, temperatures will be recorded at three depths:
surface, mid-depth, and near the bottom. If the plume crosses the 18-ft depth contour, it can be identified by the difference between the surface temperature and temperature at depth. The vertical profiling current meters will provide data to assess if conditions exist that would cause an incursion of heated water (i.e., currents with an onshore component).
Also, incursion of heated water at more than one coastal station simultaneously would be highly unlikely. Therefore, the stations where incursion of heated water is unlikely can be used to determine if natural temperature stratification is present in the coastal ambient temperature profile. This information will be used to determine the temperature rise caused by the heated water incursion.
2.3 Potential for Re-entrainment of Heated Water An ambient temperature monitoring station has been incorporated into the HWPOS to ensure that all necessary data are available to make the assessments required by Condition 17. Ambient temperature data will be used as the baseline against which intake temperatures will be compared. In this manner, any detected rise in the temperature of intake water relative to the ambient temperature will be evaluated.
The coastal monitoring stations are not used for intake ambient monitoring because the velocity caps (intakes) are in deeper open waters.

103-87735 3.0 STATION LOCATION There are five types of monitoring stations included in the HWPOS:
Surface Discharge Monitoring Stations 18-ft Contour Monitoring Stations Cooling Water Intake Monitoring Station Ambient/Background Monitoring Station Intake and Discharge Canal Monitoring Stations The offshore monitoring stations will consist of single and multiple-temperature logger arrays located in water depths from 18 ft to approximately 30 ft (see Figure 2).
The criteria used to select the station locations are discussed below.
3.1 Surface Discharge Monitoring Stations Surface discharge monitoring stations will be located where the thermal plume modeling predicts maximum surface temperatures under zero ambient current conditions.
Figure 2 shows the recommended locations for the proposed surface discharge stations (solid green dots).
The surface monitoring stations near the Y-discharge will be installed along the centerline of the discharge pipes approximately 75 to 150 ft from the point of discharge (see Insert A, Figure 1). The final location will be determined during station deployment by measuring surface temperatures and placing the station at the location with the maximum observed temperature. For the multiport diffuser, one monitoring station will be located approximately 25-ft north of the centerline of the discharge pipe and about 400-ft offshore from the start of the diffuser. This location corresponds approximately to the point of maximum temperature as predicted by the thermal modeling (see Insert B, Figure 1). The final location will be determined during station deployment by measuring surface temperatures and placing the station at the location with the maximum temperature. The final station locations will be mapped using GPS navigation. Temperature loggers at these three stations will be installed at the surface only.
To define the surface temperature increase of the heated water it is important to note that the heated water rises above the ambient water and the near-surface temperature is the important measurement.
Also, since the heated water moves up and down with tides and wave motion, the plume measurement needs to be relative to a moving surface. Therefore, to ensure that these stations are always measuring the water temperature within 1 to 2 ft of the surface, the thermometers will be mounted to the bottom of the surface buoys.
3.2 18-ft Contour Monitoring Stations The 18-ft contour, as determined from Coast & Geodetic Survey charts, is the demarcation line between the Open Ocean and Coastal Waters as defined in Chapter 62-302.520, F.A.C.
Therefore, three monitoring stations (one north of the Y-discharge pipe, one south of the intake structures, and one
.,older Asociates
June2011 6
103-87735 between the St. Lucie Plant's discharge pipes) will be established at the 18-ft. contour (solid red dots, Figure 2).
The monitoring station at the 18-ft contour midway between the two discharge pipes is designed to cover an onshore current condition. This is also the closest point in coastal waters to the source of heated water. The north and south monitoring stations will be located approximately 0.5 to 1 mile north and south of the discharge structures. These are the two segments of the shoreline where the thermal plume modeling shows the greatest possibility of plume encroachment into coastal waters when the offshore currents are predominately from the north or south.
All three of these monitoring stations will have temperature loggers near the surface, at mid-depth, and near the bottom.
3.3 Cooling Water Intake Monitoring Station In order to evaluate the potential re-entrainment of the heated plume, a monitoring station will be deployed near the water entrance to the intake velocity caps (open red circle, Figure 2).
For this monitoring station, two temperature loggers will be located at a water depth equal to the intakes and one additional logger will be installed near the surface to determine if heated water passes above the velocity caps, without affecting the temperature of the water entering the plant.
For the intake temperature measurements the elevation above the seafloor is the critical reference as the intake structure is at a fixed elevation.
Therefore, the intake thermometers will be mounted at the elevation corresponding to the mid-point of the velocity cap openings.
For the surface temperature measurement the thermometers will be mounted to the bottom of the surface buoy.
3.4 Ambient/Background Monitoring Station To meet the requirements of the Administrative Order, it will be necessary to record the temperature of the ambient water (i.e., water unaffected by the heated water discharge). To optimize the collection of ambient/background data, a temperature monitoring station will be established offshore and southeast of the intake structures (open green circle, Figure 2). The Ambient/Background Monitoring station location and instruments (thermometers) array was selected to address the following considerations:
The monitoring station must be seaward of the most seaward 18-ft depth contour.
The monitoring station should be near the intake structures.
The monitoring station should be outside the hydraulic influence of the intake structure.
Based on the quantity of water withdrawn, there should be at least 500 ft between the ambient monitoring station and the nearest intake structure.
The intake structure is located in 24 ft of water. Therefore, the ambient monitoring station should be located in water at least 30-ft deep, so that the lowest thermometer can be mounted above the anchor structure at a depth about equal to the water depth at the intake (24 ft).
To minimize potential influence of the discharge plume and simultaneously minimize the distance from the intake structure, the ambient monitoring station should be located southeast of the intake structure.

Six thermometers will be installed at the ambient monitoring station at the following depths:
0 0
0 0
S 2 ft below the surface (surface temperature) 7 ft below the surface (top of the intake structures) 12 ft below the surface (top of the intake opening) 15 ft below the surface (middle of the intake opening) 18 ft below the surface (bottom of the intake opening) 24 ft below the surface (depth at the intake structures)
With this vertical array of instruments, if the thermal plume reaches the monitoring station, the vertical extent of the plume can be established and the appropriate ambient temperature can be determined.
3.5 Intake and Discharge Canal Monitoring Stations To assist in evaluating the extent of recirculation of heated effluent to the plant intake, an additional temperature monitoring station will be located at the eastern end of the intake canal; near the headwall at the entrance to the intake canal (solid green dot, Figure 2). These thermometers (primary and backup) will be located at mid-depth near the inflow point, where the water is well mixed. The temperature loggers installed at this location will be mounted to a secure fixed structure. The design for the logger mount will be approved by FPL prior to installation.
Temperature data from the existing installed plant temperature instruments at the intake (permit monitoring station INT-1, not shown on Figure 2) and at the point-of-discharge (permit monitoring station EFF-2, yellow dot with red border shown in Figure 2) will also be obtained and used for this analysis.

103-87735 4.0 INSTRUMENTATION Real-time monitoring of water temperature data is not required for the HWPOS. Therefore, non-cabled, stand-alone, diver-serviced temperature loggers will be installed. Onset HOBO Pro V2 temperature data loggers will be used. The small size of the HOBO Pro V2 allows for easy installation and servicing in the field. The accuracy, precision, and range of the HOBO Pro V2 temperature data logger provides for excellent data collection for the expected temperatures of the project (see Appendix A -
Equipment Specifications). The operational range for these temperature loggers is -40°Celsius (0C) to 700C (-400 F to 1580 F).
The temperature loggers will be factory calibrated and verified before deployment using NIST-traceable standard thermometer at several temperatures in the expected sample measurement range following appropriate FDEP SOPs. A NIST calibration certificate will be provided for each temperature logger.
The following procedure will be used to ensure that all temperature loggers are providing consistent temperature readings over a range of temperatures and to document any small systematic deviations.
Then, corrections can be applied as necessary and appropriate to individual loggers to obtain consistent temperatures. Before the temperature loggers are deployed for the heated water study, all the loggers will be deployed simultaneously and in close proximity to one another for at least 24-hours; first in the discharge canal near the FPL discharge monitoring station and then in the ocean. The discharge canal is well mixed and will act as a warm water temperature bath. The ocean will act as the cool temperature bath.
Immediately following deployment in these two locations, the data will be downloaded and the temperature from each thermometer will be compared to the temperature from the discharge monitoring station and to the average of all the temperature loggers.

103-87735 5.0 MONITORING STATION BUOY ARRAY The temperature array consisting of a surface buoy, multiple subsurface buoys, and an anchor will be used for each monitoring station (see Figure 3). This design provides less buoy surface area in the upper water column where most of the hydrodynamic forces induced by currents and wave action exist. The subsurface buoys, which are installed at regular intervals along the mooring cable, will provide the support needed to maintain the temperature loggers at their required depths in the water column and reduce the overall movement of the mooring. The number of subsurface buoys will be determined based on the number of temperature loggers to be installed. A minimum of three subsurface buoys will be used to maintain design requirements. The surface buoy provides easy location, day markings, and a suitable structure for lighting.
The anchor, cable, hardware and buoys used for the monitoring buoy array will be constructed so that the temperature loggers and array components will be able to withstand a reasonable degree of accidental entanglement due to high boat traffic, anchor or fishing line entanglement, divers/swimmers, etc., and intentional vandalism. An assessment of the monitoring station array construction will be made during the first month maintenance/service event and needed modifications will be implemented.

June2011 10 103-87735 6.0 DATA COLLECTION All data collection efforts for this project will follow FDEP approved quality assurance/quality control (QA/QC) procedures.
Because the HOBO Pro-V2 temperature loggers are small and relatively inexpensive, redundant loggers will be installed along with each primary logger.
All temperature loggers will be installed, retrieved, maintained, and serviced using SCUBA divers. The Pro-V2 loggers will be removed from the mooring, and the recorded data will be downloaded to a computer on board the diving support vessel. Once the data download is completed and verified, the loggers will be reinstalled on the mooring.

June 2011 11 103-87735 7.0 MAINTENANCE AND SERVICING Regular scheduled maintenance/servicing events are critical to keeping the thermal monitoring systems functioning properly and to ensure acceptable data recovery.
Initially, monthly maintenance/servicing events will be conducted to ensure instrumentation/data is not being compromised, by accident or vandalism, to the point where the required data can't be retrieved to meet the study objectives. After the first 3 months, it will be determined if more or less frequently scheduled maintenance/servicing events will provide for confident data collection.
During each maintenance/servicing event, all buoy and mooring components will be checked for wear and replaced if necessary. The mooring station location will be verified using GPS navigation equipment, and repositioned if necessary.
Additional contingency maintenance/servicing events (including temporary monitoring station removal, if necessary) will be conducted in the event of storms or other identified equipment problems.

4 June 2011 12 103-87735 8.0 CURRENT PROFILING An Acoustic Doppler Current Profiler (ADCP) that can provide current direction and velocity at multiple levels (i.e., multiple depths throughout the water column) will be installed offshore south of the diffuser discharge (solid red rectangles, Figure 2). A second ADCP will be installed at the 18-ft contour between the discharge pipes. The current data will provide an indication of discharge water movements from the near shore location and the offshore location.
A Nortek Z-cell 1 megahertz (MHz) model ADCP will be used for this project (see Appendix A -
Equipment Specifications). The Z-cell 1 MHz was chosen to achieve the best accuracy and resolution for the expected water depth of the study area.
The Nortek Z-cell ADCPs are factory calibrated and, with the exception of the internal compass, do not require field calibration, as long as the transducer heads are not physically deformed.
Prior to deployment, a compass calibration will be performed and documented. Also, at the completion of the project, the ADCPs will be sent back to the factory for calibration verification.
