FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Executive Summary EXECUTIVE
SUMMARY
Florida Power & Light Company (FPL) has prepared this Comprehensive Pre-Uprate Monitoring Report pursuant to Conditions of Certification IX and X of its Power Plant Site Certification for the FPL Turkey Point Units 3 and 4 Nuclear Power Plant and Unit 5 Combined Cycle Plant (PA 03-45A2). The Monitoring Plan was developed with input from the Florida Department of Environmental Protection (FDEP), the South Florida Water Management District (SFWMD), and Miami-Dade Countys Department of Environmental Resources Management (DERM),
(collectively, the Agencies), and FPL. The Monitoring Plan requires the collection of groundwater, surface water, meteorological, flow, and ecological data in and around the plant to establish pre-Uprate baseline conditions and determine the horizontal and vertical effects and extent, if any, of the cooling canal system (CCS) water.
FPL has prepared this Comprehensive Pre-Uprate report to document its efforts to establish a pre-Uprate baseline conditions for the required two year pre-Uprate period. The purpose of this report is to summarize and provide analysis of the data collected. This report incorporates information presented in the previous semi-annual reports (FPL 2011a, FPL 2012a) and first annual report (FPL 2011b). It includes data from June 2010 through June 2012.
In accordance with the Monitoring Plan, FPL installed an extensive monitoring network of 47 groundwater wells and 20 surface water stations, a meteorological station, rainfall gauges, and flow meters in the CCS and surrounding area. The groundwater and surface water stations measure and record specific conductance, salinity, water levels, and temperature at 15-minute intervals. Groundwater and surface water samples are collected across the vast network of stations every three months and analyzed for a broad suite of parameters. FPL conducted extensive ecological monitoring and studied flora and fauna in Biscayne Bay, marshes, and mangroves. Initially, FPL collected water samples from the shallow soils (referred to as porewater) at hundreds of locations that covered a 75 square mile area in the vicinity of the CCS and analyzed for a broad suite of parameters.
As required by the Monitoring Plan, FPL has developed a water budget. This analysis calculates components of water and salt inflow and outflow from the CCS on a daily basis. The water budget helps explain the dynamics of CCS hydraulics and may be used to assess the effect of climatic or operational changes on the CCS water levels and salinities.
The Agencies and their experts considered and analyzed the previous data collected and have selected tritium as the tracer. FPL disagrees with the low tritium threshold that the Agencies selected when evaluating potential movement of the CCS. Tritium is a by-product of the nuclear fission process and is unique to and present in and around the CCS. It is important to note that tritium is being measured only as a chemical tracer in order to determine the potential movement of CCS water. At the levels being measured, the tritium is not a public health concern. Tritium is ES-1
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Executive Summary routinely monitored in the CCS by the Florida Department of Health, Bureau of Radiation Control and there have never been results detected near the drinking water standard (20,000 picoCuries per liter).
The results of the two years of pre-Uprate data analysis are summarized below.
Biscayne Bay groundwater results support the conclusion that there is little or no influence from the CCS in the area fronting the northern half of the CCS. However, there is evidence of CCS water under Biscayne Bay in close proximity to the southern tip of the CCS. Over the two year monitoring period, the results indicate that the salt constituents and tracer have remained consistent for all wells. This is indicative of the groundwater maintaining a relatively stable condition during this time period.
Groundwater results immediately adjacent to the CCS indicate the presence of CCS water.
Further west from the CCS, there is some influence of CCS water in decreasing concentrations at depth out approximately three miles. The outermost wells approximately six miles to the west are fresh at all depths. Similar to the wells in the bay, the results indicate the salt constituents and tracer have remained consistent for all wells. This is indicative of the groundwater maintaining a relatively stable condition during this time period. A shallow fresher water lens still exists west of the CCS and is supported by the induction logging conducted for this project and the continuous specific conductance profiling done in several historical wells for the interceptor ditch (ID) monitoring. This lens is 10 to 20 feet deep from the surface and generally thickens towards the west.
In most surface water stations, there is no influence of CCS water via groundwater pathway.
There are two locations in the surface water canal stations immediately adjacent to the south end of the CCS where there appears to be some CCS water present.
FPL concludes the CCS does not have any ecological impact on the surrounding areas. FPL further concludes there is no evidence of CCS water in the surrounding ecosystems from a groundwater pathway.
FPL concluded that atmospheric deposition of the tracer can affect the surface water, porewater, and very shallow groundwater results as indicated by measured concentrations of tritium and must be considered when evaluating CCS surface water and porewater results. These tritium values are more concentrated immediately adjacent to the CCS and diminish with distance from the CCS.
It is important to understand the historical context of saltwater in the region and to the west of the CCS. Saltwater intrusion pre-dates the construction of the CCS and extended far inland in the 1940s (Klein 1957). Based on historical data, much of the groundwater in the vicinity of the CCS was non-potable. The extent of saltwater intrusion, as defined by the U.S. Geological Survey, varies from year to year but the landward extent of the saltwater intrusion today is still similar to that reported in the 1950s.
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Executive Summary FPL and the Agencies conducted a joint study separate from the Monitoring Plan to determine the landward extent of the saltwater orientation in the region prior to construction of the CCS. In August 2011, FPL and the Agencies reached agreement on the conclusions as documented in a report Saltwater Orientation in the Biscayne Aquifer in the Turkey Point Plant Vicinity Prior to Installation of the Cooling Canal System. Based on data from the Monitoring Plan, as compared to this report, the western historical extent of saltwater has not changed appreciably since the construction of the CCS in 1972. In fact, all the well clusters furthest to the west contained freshwater historically and still do today. Directly beneath and adjacent to the CCS, the saltwater wedge is closer to the land surface than it was prior to the CCS installation.
In conclusion, FPL has completed two years of pre-Uprate baseline monitoring. Many factors can cause saltwater intrusion, including groundwater withdrawals, agricultural uses, mining, government water management practices, etc. The impact of CCS water at a particular location, the relevancy of its presence, and how the water reached that location, must be considered when assessing the results and determining how to proceed.
FPL has recommended some changes to the monitoring, particularly in the interim period until 2013 when the Uprates of both Turkey Point nuclear units will be completed and those units returned to service at the Uprated power levels. Lastly, FPL makes recommendations in this report that some of the analytical parameters be eliminated.
Going forward, FPL will continue to comply with the Monitoring Plan for the required two year post-Uprate monitoring period. Since increases in temperature and salinity are expected to be minimal after the Uprate Project is implemented, there should be no presumption that the Project will cause any impact to the surrounding environment. The post-Uprate monitoring will help determine if there are any measurable impacts.
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1
- 1. INTRODUCTION Florida Power & Light Company (FPL) submits this Comprehensive Pre-Uprate Monitoring Report dated October 2012 for the Units 3 and 4 Uprate Project. This monitoring report has been prepared in accordance with the FPL Turkey Point Power Plant (Turkey Point) Groundwater, Surface Water, and Ecological Monitoring Plan, referred to herein as the Monitoring Plan (South Florida Water Management District [SFWMD] 2009a). The Monitoring Plan requires the collection of groundwater, surface water, meteorological, flow, and ecological data in and around the plant to establish pre-Uprate baseline conditions and determine the horizontal and vertical effects and extent, if any, of the cooling canal system (CCS) water. For further details, refer to the Monitoring Plan (SFWMD 2009a) and Fifth Supplemental Agreement (SFWMD 2009b).
The purpose of this Comprehensive Pre-Uprate Monitoring Report is to summarize the pre-Uprate monitoring efforts, to present and summarize the data, and to discuss results. This report incorporates information presented in the previous semi-annual reports (FPL 2011a, FPL 2012a) and annual report (FPL 2011b) and includes data from June 2010 through June 2012.
Data were collected in accordance with the FPL Quality Assurance Project Plan (QAPP) that was available at the time of sample collection (FPL 2010 and 2011c) as well as changes to the QAPP that the SFWMD, the Florida Department of Environmental Protection (FDEP), and the Miami-Dade County Department of Regulatory and Economic Resources (RER, formerly known as Department of Environmental Resource Management [DERM]) (collectively described herein as the Agencies) provided to FPL in June 2011 and the suggested revisions that FPL provided to the agencies in August 2011 and March 2012. FPLs suggested revisions more accurately reflect data collection practices being performed in the field. Any notable deviations are discussed herein and/or are found in the field and laboratory audits (SFWMD 2011, 2012a, and 2012b; FPL 2012b and 2012c).
1.1 Brief Overview of Automated Monitoring Network FPL installed an extensive automated monitoring network to collect groundwater, surface water, meteorological, and hydrologic data at 15-minute intervals over a broad area surrounding Turkey Point. Table 1.1-1 provides a summary of monitoring efforts and includes information on when the automated monitoring was initiated. A brief overview of each monitoring network is provided below, and further discussion regarding the instrumentation, data collection, and results for the network is included in Section 2 of this report. Photographs of the automated stations are included in Appendix A.
1.1.1 Groundwater From February through June 2010, FPL installed 42 wells in 14 well clusters (TPGW-1 to TPGW-14) at and around Turkey Point (Figure 1.1-1). Coordinates of each station are provided 1-1
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 in Appendix A. The locations were determined based on site conditions and extensive coordination among FPL and the Agencies. The placement of station locations in Biscayne Bay also was coordinated with Biscayne National Park (BNP).
Three separate wells were installed at each location: a shallow well (S); an intermediate depth well (M); and a deep well (D). The borehole for the deep well was drilled first, and down-hole geophysical methods were used to help determine high flow zones and other subsurface characteristics. Based on a collaborative effort among FPL, JLA Geoscience, Inc., and the SFWMD, screen depths were established with screen lengths varying from 2 to 5 feet (ft) based on site conditions. Table 1.1-2 provides a brief summary of the well construction information, and further details are provided in the JLA Geosciences, Inc. (2010) Geology and Hydrogeology Report.
Following well completion, the top of each well casing was surveyed and infrastructure (probes, telemetry, solar panels, and other elements) was installed to facilitate the collection of automated groundwater quality and stage data at 15-minute intervals. Most of the locations were re-surveyed in June 2011 to confirm the elevations. The measured water quality parameters include actual conductance and temperature. Specific conductance, salinity, density, and total dissolved solids (TDS) are calculated by the instrumentation based on the measured parameters.
Groundwater data are remotely transmitted via telemetry each day and uploaded to FPLs Electronic Data Management System (EDMS).
1.1.2 Surface Water Per the Monitoring Plan and as shown on Figure 1.1-2, automated surface water stations were installed at the following locations:
Seven stations in the CCS; Five stations in adjacent canals; Three stations in the Interceptor Ditch (ID); and Five stations in Biscayne Bay.
In addition, two non-automated stations were installed:
One station in the CCS (TPSWCCS-8); and One station in the Card Sound Road Canal (TPSWC-6).
The locations of the monitoring stations were jointly determined with the Agencies and provide broad coverage of the key water bodies in the project area. Two additional stations (TPBBSW-10 and -14) were added at a later date to record conditions in Biscayne Bay; these stations are co-located with TPGW-10 and -14. Coordinates of each station are provided in Appendix A.
The automated surface water stations record the same water quality data parameters as the groundwater stations. Stage data are recorded at all locations except four stations in Biscayne Bay that do not have the infrastructure to support stage recorders or a telemetry system 1-2
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 (TPBBSW-1, TPBBSW-2, TPBBSW-4, and TPBBSW-5). The data at these four Biscayne Bay locations are retrieved manually at approximately six-week intervals and downloaded into the FPL EDMS. Data from the other stations are transmitted via telemetry daily onto a secure server system and automatically uploaded into the FPL database.
1.1.3 Meteorological One meteorological station that includes instrumentation to measure solar radiation, wind speed, wind direction, air temperature, relative humidity, and rainfall was installed near the center of the CCS (TPM-1). Four additional rainfall gauging stations were installed around the CCS. Data are collected at 15-minute intervals. Data from the meteorological station are uploaded daily into the FPL database, while the rainfall gauges are manually downloaded during routine site visits. Seven rainfall collectors were installed around the CCS. Additionally, five evaporation pans have been installed at various locations. Figure 1.1-3 illustrates the locations of the above-mentioned stations. Coordinates of each station are provided in Appendix A.
1.1.4 Hydrological Three acoustic Doppler velocity meters (ADVMs), otherwise known as index-velocity meters or flow meters, were originally set up to determine flow in the CCS at the following three locations:
near the power plant discharge into the CCS; the southern end of the CCS before the water enters the return canal of the CCS; and near the intake into the plant from the CCS (Figure 1.1-4). All three units failed within the first two years of deployment due to the harsh conditions within the CCS; two units have subsequently been re-installed and are currently operational. Data are transmitted by telemetry and automatically uploaded to the FPL EDMS.
1.2 Quarterly Sampling for Laboratory Analysis The aforementioned monitoring network for groundwater and surface water supports the collection of water samples for laboratory analysis. The Monitoring Plan specifies samples must be collected from the 42 new groundwater wells and the 20 surface water stations previously discussed. Samples also must be collected on a quarterly basis from one additional location on the Card Sound Road Canal. In addition, a sample must be collected one time at a localized location within the CCS, identified by the Agencies as potentially having cooler water than the rest of the CCS, based on thermal imagery. The timing of the quarterly sampling efforts is shown on Table 1.1-1. The samples are analyzed for a variety of parameters including CCS Tracer Suite constituents, ions, trace elements, nutrients, and TDS, along with field parameters, depending on the locations and whether the effort was a quarterly or semi-annual event.
Further discussion of the analytical parameters, sample collection methods, and results is provided in Section 3 of this report. The analytical data include sampling events conducted in June/July 2010, September 2010, December 2010, March 2011, June 2011, September 2011, December 2011, March 2012, and June 2012.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Samples were also collected at five existing historical wells as part of FPLs routine sampling for the ID operation. Samples were collected from historical wells L-3, L-5, G-21, G-28, and G-35 in October 2010 and January 2011. Initially, the timing of these sampling events was offset from the Monitoring Plan sampling events but, based on discussions with the Agencies following the January 2011 sampling effort, FPL changed the ID operation sampling to occur in the same month as the Monitoring Plan sampling. Results from the March 2011, June 2011, September 2011, December 2011, March 2012, and June 2012 sampling events, as well as the October 2010 and January 2011 events, are included in this report.
1.3 Ecological Monitoring The Monitoring Plan and QAPP outline an ecological monitoring program. Biotic components of interest include marsh vegetation in adjacent wetlands, mangroves, submersed aquatic vegetation, and benthic fauna in and adjacent to Biscayne Bay. Table 1.1-1 provides a summary of the ecological monitoring efforts conducted. More detailed information on the transect plot setups, sampling methods and materials, laboratory results, findings, and conclusions are included in Section 4 of this report.
1.3.1 Marsh and Mangroves Plant community characteristics (composition, cover, canopy, height, productivity), leaf characteristics, nutrient content in the leaves and soil/sediment, and porewater quality are being assessed in 12 transects in marsh and mangrove areas around the CCS (Figure 1.3-1). Two (one each in the marsh and mangrove) of those transects are in reference areas. Ecological monitoring efforts were initiated in October 2010 and completed by December 2010. Additional monitoring in the marsh and mangrove areas was conducted on a quarterly basis in February 2011, May 2011, August 2011, November 2011, February 2012, and May 2012.
1.3.2 Biscayne Bay Submerged aquatic vegetation (SAV), coral and sponge community composition and cover, fish and invertebrate species composition and abundance, nutrient content in seagrass leaves and sediment, light attenuation, and porewater quality are being assessed in 20 transects that parallel the shoreline (Figure 1.3-1). The monitoring in Biscayne Bay is conducted twice a year.
Originally, the plan was to conduct monitoring in May and October; however, during the setup of transects in October 2010, FPL noted that the seagrasses had already senesced by the time sampling was initiated. With concurrence from the Agencies, the subsequent ecological monitoring in Biscayne Bay was changed to April and September with the subsequent monitoring efforts conducted in April 2011, September 2011, and April 2012.
1.3.3 Broad-Scale Porewater Survey In accordance with the Monitoring Plan and through coordination with the Agencies, an initial broad-scale survey of porewater temperature and specific conductance was conducted in March/April 2010 (dry season) at over 200 locations in adjacent wetlands and Biscayne Bay 1-4
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 (Figure 1.3-2). A second porewater temperature and specific conductance survey was conducted in August 2010 (wet season) at 100 locations in Biscayne Bay (Figure 1.3-3). Based on the initial temperature and specific conductance measurements, locations were established for the porewater samples that would be collected for Tracer Suite laboratory analysis. The wet season Tracer Suite sampling effort took place in October 2010 and the dry season sampling event was conducted in April 2011. While details of this effort are in the report titled Turkey Point Plant Initial Ecological Characterization Report (FPL 2012d), summaries of the approach and the findings are provided herein. The results, when used in conjunction with the other data, increase understanding of baseline porewater conditions across the broader landscape.
1.4 Hydrogeologic Assessment 1.4.1 CCS Water Budget FPL has worked closely with the Agencies to develop an acceptable methodology for the CCS water budget. This methodology has evolved and is included in Section 5 of this report.
Estimated monthly water budgets and salt loads from September 2010 through June 2012 are included in Section 5.
1.4.2 Regional Assessment and Extent of CCS Water With the aid of data collected as part of the well installation efforts, automated data and analytical results, United States Geological Survey (USGS) induction logs, and other supporting documentation, FPL has conducted an initial assessment of the hydrogeologic conditions in the area surrounding Turkey Point and the CCS, which provides some insights into how the groundwater system responds to different environmental conditions and operation of the CCS.
The rate of migration and extent of CCS water in the groundwater are discussed in Section 5 of this report.
1.4.3 Biscayne Bay Continuous Resistivity Profile Survey The USGS conducted a pilot study in Biscayne Bay to assess the feasibility of using continuous resistivity profiling to determine the extent of CCS water both laterally and vertically in the subsurface. The survey in the Bay was conducted on May 25 and 26, 2011, with an additional transect surveyed in the CCS in July 2011. Following the processing and interpretation of the data, the USGS gave a PowerPoint presentation to FPL and the Agencies on August 29, 2012.
No report was generated to provide the information to the Agencies. The USGS indicated that preparation and publication of a report would take approximately one year due to their extensive quality assurance/quality control (QA/QC) process. Alternatively, FPL provides a brief summary of the USGSs effort and FPLs overall interpretation of the preliminary findings in Section 5 of this report.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 1.5 Interceptor Ditch Operation The Interceptor Ditch (ID) is located immediately west of the CCS and is designed to prevent seasonal inland movement of saltwater from the CCS into the potable portion of the Biscayne Aquifer. Shallow saline groundwater is intercepted by the ID and pumped back to the CCS during the dry season or other times when the natural gradients are low and the potential for saltwater intrusion exists. Details of the ID operation are found in the 1983 Agreement (the Agreement) between the SFWMD and FPL. On October 14, 2009, the Agreement was modified to expand the monitoring program as part of the Turkey Point Units 3 and 4 Uprate Project and added well G-35 as part of the historical monitoring network. FPL submitted a revised operations plan to the SFWMD in 2011 and comments on that plan are pending.
Since 1972, FPL has been collecting groundwater data west of the CCS and recording ID pumping as part of the ID operation. Results of these efforts have been included in reports that are submitted on a quarterly and annual basis. Based on discussions between FPL and the SFWMD, reporting of the ID operations for the last year (June 2011 through May 2012) is integrated into Section 6 this report.
1.6 Data Quality Objectives and Acceptance Criteria Data quality objectives (DQOs), along with acceptance criteria, are identified in the project QAPP. The DQOs include the following:
Precision Accuracy Analytical Sensitivity Completeness Representativeness Comparability Availability Reliability Maintainability Timeliness Quality guidelines have been established for some of the DQO which reflect quantifiable goals.
A summary of performance in meeting the DQOs is described below.
Precision Precision is a measure of mutual agreement between duplicate or co-located measurements of the same analyte. The closer the numerical values of the measurements are to each other, the more precise the measurement.
1-6
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Precision for laboratory samples is established by the evaluation of field and laboratory duplicate samples. If the relative percent difference (RPD) between the sample and the duplicate result differ by more than 20%, the results for that analyte in both samples are qualified as questionable. While a small percentage of sample data has been qualified due to high duplicate RPDs, overall, the analytical results are comparable to duplicate samples for those samples using the same method. These precision results indicate the sampling and analytical procedures are consistently performed and repeatable. Details are provided in the Data Usability Summary (DUS) Reports issued for each event.
To assess precision of the probes being used to collect time series water quality and water level data, field measurements are taken during cleaning and calibration events to verify the results.
This is discussed further in Section 2 of this report. If the specific conductance value reported by the field verification measurement is more than 30% higher or lower than the automated probe reading, the automated probe data are qualified as questionable (?) back to the previous cleaning and calibration event or, at minimum, back to an interim point where there is an unexplained shift in the data. While most of the data do not need to be qualified, the numerical degree of variability is greater in the high saline locations.
Similarly, if a temperature verification measurement is more than 0.5 degrees Celsius (°C) different than the automated probe reading, the data are qualified in the same manner. Rarely has the water quality data been qualified for not meeting a field instrument verification reading.
For verification of water level precision, refinements were made during the monitoring program.
These refinements included the collection of water level measurements with a water level indicator at different times during the cleaning and calibration event. These refinements allowed the determination of the water level before pulling the probes for cleaning and after placement of the probes to verify correct reference level settings. If the difference between the verification water level reading (before the probe is pulled for cleaning) is greater than 0.1 ft from the automated probe reading, the data are qualified as estimated (J) back to the previous cleaning and calibration event or, at minimum, back to an interim point where there is an unexplained shift in the data. The precision has improved over time; however, the biggest challenge has been associated with the surface water stations in Biscayne Bay and the CCS. Sometimes wave action at these larger surface water body locations affects the water level indicator readings, making verification of the automated reading more difficult. Only a limited amount of water level data is qualified as questionable due to verification readings.
Accuracy Accuracy is the measure of bias in a measurement system. The closer the value of a measurement agrees with the true value, the more accurate the measurement.
For the analytical results, accuracy is evaluated using percent recoveries of analytes added, termed spiked, to samples (matrix spikes [MSs]) or reagents (laboratory control samples
[LCSs]) and carried through the extraction and analysis procedure. Laboratory-established acceptance criteria (within method requirements) are used for LCS and MS percent recoveries.
1-7
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 LCS percent recoveries have consistently passed acceptance criteria for all analyses indicating the laboratories extraction and analysis procedures and materials met method requirements.
In contrast, some MS recoveries have been qualified as estimated (J) or unusable (?) due to poor recoveries. Results with MS recoveries outside laboratory-established limits are qualified as J and recoveries less than 10% are qualified as ? as the low recovery indicates a significant possibility of error associated with the sample result due to the matrix effects. Results were qualified as ? in two total phosphorus, one chloride, one sulfate, and one fluoride result in saline water samples. Results were qualified as J in many of the samples analyzed for matrix spikes, especially with regards to nutrients. This trend will be followed during future events as it could indicate a possible error associated with the accuracy of the results due to matrix interferences.
In addition to recoveries, accuracy is evaluated using technical comparison checks, including cation and anion charge balance; cations, anions, and TDS compared to the specific conductance; total ammonia less than total Kjeldahl nitrogen (TKN); and orthophosphate (OP) less than total phosphorus (TP). Many cation and anion results, particularly in the high salinity samples, have been qualified as either J or ? due to ion charge and conductance comparisons. TDS/specific conductance and ammonia/TKN comparisons were acceptable.
TP and OP were first sampled in events from June 2010 to February 2011 and the OP had higher results than the TP. In March 2011, the OP analytical method was modified based on a FDEP Laboratory SOP (NU-070-1.8). The sample is analyzed without the color reagent to establish a background concentration. The sample is then analyzed per the method and the background concentration is subtracted from the analytical result. Since the method modification, the OP/TP comparisons have been within the criteria.
The laboratory is considering switching to saline reagent waters to better simulate the sample matrix and reduce matrix-induced interference effects. In addition, certified reference materials (CRMs) for nutrients in saline waters are being analyzed to evaluate the validity of the laboratory results for these methods.
To further evaluate laboratory accuracy, field split samples were collected by RER in the March 2012 semi-annual sampling event and analyzed by the RER laboratory. Samples were collected from select deep wells into separate containers, shipped to TestAmerica Laboratories, Inc.
(TestAmerica) and the RER laboratory, and analyzed for ammonia, nitrate/nitrite, TKN, TP, and OP. While the number of data pairs compared (four) is too small to draw major conclusions, there are some significant differences (RPD>50%) among the results for ammonia, TKN, and OP. The two laboratories follow essentially the same methods; however, even minor differences in procedures or materials can affect the analytical results. At this point, it is unclear which set of results is more accurate of the actual groundwater conditions at the time of sampling. It should be noted that the RER results have ammonia consistently greater than TKN, which is not possible; TKN is the sum of ammonia, ammonium, and organic nitrogen. FPL/TestAmerica is reviewing the RER SOPs and is performing analysis of CRMs to aid in the evaluation of the overall sample results.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 The instrumentation for all the automated station instruments and field equipment meets the requirements for accuracy per the QAPP. All stations were surveyed with vertical control established to second order closure (accuracy within hundredths of a foot) with the exception of three groundwater cluster stations in Biscayne Bay. The top of the groundwater wells and surface water stilling wells at these Biscayne Bay stations were surveyed with GPS instruments to an accuracy of 0.1 ft.
Analytical Sensitivity For data validation, qualification and reporting purposes, analytical sensitivity is expressed by method detection limits (MDLs). MDLs are set such that the minimum concentration of an analyte is reported within 99% confidence that the analyte is greater than zero.
Project-required MDLs are listed in Table 3.2-1 of the QAPP. The MDLs are based on applicable criteria, MDLs listed in the Automated Data Processing Tool (ADaPT), Florida Administrative Code (F.A.C.) 62-4.246(3), and stated laboratory capabilities. While the majority of analytical detection limits have met the QAPP requirements, a few have been difficult to achieve due to the saline nature of the samples. This is particularly an issue with the trace metals and fluoride. The laboratory has had to dilute the saline samples to keep instruments from being overloaded with the major ion constituents (i.e., chloride, sodium). This has resulted in some data reported as Not Detected (U) but with detection limits above the QAPP requirements. In addition, these dilutions increase the uncertainty, or error, associated with a result. The laboratory is working to expand or tailor calibration ranges, within method requirements, to fit project samples and reduce the frequency of dilutions needed.
To achieve the required MDLs, the laboratory will be adding preparatory EPA Method 1638 (Determination of Trace Elements in Ambient Waters by Inductively Coupled Plasma Mass Spectrometry) for manganese and molybdenum and EPA Method 1640 (Determination of Trace Metals by Pre-concentration and ICP-MS) for the other trace metals listed above starting in September 2012. The added step will selectively concentrate certain metals prior to analysis to improve detection limits. For fluoride, the laboratory has modified the instrument performing the anion analysis (Method 6010) to allow for lower required dilutions and achieve the QAPP-required MDL. In addition, a fluoride selective probe method is being reviewed as a possible analytical alternative for fluoride only.
Completeness Completeness is expressed as the percentage of valid or usable measurement to planned measurements. The higher the percentage, the more complete the measurement process. The number of planned measurements is based on when the infrastructure is in place and functional.
Per the QAPP, the completeness goal for water quality measurements is 95% and 90% for all other data.
All planned groundwater, surface water, and porewater measurements have been made with a few exceptions. The well clusters at TPGW-10, TPGW-11, and TPGW-14 were not sampled 1-9
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 during the June 2010 event as they had not been completed at that time. Some data have been qualified as unusable and, in a few instances, the sample was lost by the lab prior to analysis.
For the nine groundwater and surface water events (four quarterly and five semi-annual) since the start of the project, approximately 31,000 groundwater and surface water analytical data points were scheduled to be reported. Of those, fifteen results were qualified as unusable and thirty results (all isotopes) were not reported due to laboratory errors. For the seven porewater sampling efforts conducted at the ecological transects since the start of the project through May 2012, a total of approximately 10,600 porewater analytical data points were scheduled to be reported. Of those, four (all OP) were reported as unusable and twelve results (isotopes and ions) were not reported due to loss of the sample by the laboratory. This results in a completion rate of greater than 99% in meeting the project objectives. It should be noted that some isotope results have not been received at the time of this assessment and as such, the totals reported above are based on available data.
All the planned ecological measurements have been made with the exception of eliminating the collection of some data in the tree islands due to health concerns about excessive poison ivy on the islands. Any changes in sampling have been agreed to by the Agencies.
The automated water quality data are calculated to be 89% complete. This percentage is lowered as a result of specific conductance oscillations related to probe or cable malfunctions or radio frequency wave interferences, most notably in well clusters TPGW-1 and TPGW-13. FPL and the probe manufacturer have conducted numerous efforts to fix the problem; oscillations still occur, but less frequently.
Meteorological data at TPM-1 are 99% complete. Rainfall data at other stations and CCS flow meter data are less complete. Some of the other rain gauges have had various problems including wiring issues, malfunctioning equipment, or excessive battery drain which have resulted in data gaps. Most of the rain gauge problems have been resolved but since they are not on telemetry, the potential for data gaps of one to two months can still exist if a gauge fails.
Gaps in the rain data can be addressed by interpolating results from other stations or using Next Generation Weather Radar (NEXTRAD) data from the SFWMD. Data from the CCS flow meters are less than 50% complete due in part to a number of equipment related issues. These meters are located in a harsh environment and have been removed for various reasons due to hardware components rusting and breaking or instrument failure. The flow meters were going to be used by FPL as a check to the water budget, however, based on findings discussed by FPL in Section 5, it is doubtful if the flow meter data will be used as originally envisioned.
Representativeness Representativeness is a qualitative parameter that expresses the degree to which data accurately and precisely represent the environmental condition. The sampling locations and techniques as outlined in the Monitoring Plan and QAPP provide data that are representative of conditions in the CCS and the surrounding environment.
1-10
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Groundwater wells are placed in discrete high flow zones and are spatially distributed to reflect changes in groundwater levels and quality across the landscape. Automated data are collected at 15-minute intervals, an adequate duration to reflect temporal changes in water levels, water quality, water flow, and various meteorological parameters.
Comparability Comparability is a qualitative parameter expressing the confidence with which one set of data can be compared to another. Nearly all the data, unless qualified as ? or unusable for other reasons, are comparable. Methods of data collection and analysis have remained primarily consistent over the two years of sampling. Some refinements in data collection have helped improve efficiency or verify precision, but have not necessarily improved precision.
The most notable data that may not be directly comparable are some of the nutrient results. As noted in the Accuracy section above, the method of analysis for OP was modified beginning with the collection of data in the March 2011 sampling event; OP data collected prior to March 2011 using the original method are not directly comparable to data collected during and after the March 2011 event. The data prior to the March 2011 event are believed to be biased high due to background fluorescence levels interfering with the analysis.
Nitrate/nitrite samples collected in March 2012 were filtered in the field, as will be done in subsequent events. Previously, the samples were distilled in the lab and not filtered in the field.
It is expected that the results are similar. Rarely does one find insoluble forms unless they are large particulates which would not be analyzed in any case; they would have to be removed as they would interfere with the analysis. This was further demonstrated by the March 2012 PERA split samples. The samples were analyzed as filtered and unfiltered for ammonia and nitrate/nitrite with essentially identical results. Therefore, the ammonia and nitrate/nitrite results from both method variations are considered comparable.
Availability Availability is the percentage of time that a system or function is available for service according to established criteria and the probability that the system is operating satisfactorily at any point in time, excluding times when the system is under repair. This DQO applies primarily to the automated systems.
While FPL has not calculated percentages, the stations that report automated water level and water quality collectively have a high degree of availability. These systems operate round the clock, the probes have been reliable, and spare probes and cables are on-hand to fix a problem station. The meteorological station has been reliable with no down time, thus has a high degree of available data for solar radiation, wind speed and direction, air temperature, relative humidity, and rainfall. The other rain gauges and CCS flow meters appear to record good data when operational, but some of the instruments have failed for extended periods of time. Since the individual rain gauges are not on telemetry, whether the system is operating satisfactorily or not is unknown until the site is visited monthly or bi-monthly and data are downloaded and reviewed. The CCS flow meters are more difficult to maintain.
1-11
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Reliability Reliability is the probability of a system performing a specified function without failure for a specified period of time. A failure occurs when a measurement or control action does not comply with established accuracy, completeness, or timeliness standards. This DQO applies primarily to the automated systems.
Collectively, the stations that report automated water level and water quality are reliable in the context of data usability. The associated probes that measure and record the data meet the accuracy requirements and exhibit high percent completeness. As previously indicated, some stations have reoccurring issues with oscillating specific conductance data and the precision at some of the higher saline sites is reduced; however, only a small percentage of the data are qualified ?. Reporting of the automated data from the stations on telemetry has typically been on a daily basis. However, a number of transmission/signal issues have occurred when the data have not been consistently reported within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for all stations. Still, in most instances, the data are stored internally on the probe and eventually downloaded when a phone connection is made or the data are manually downloaded into the system. The quality guideline for reliability, as stated in the QAPP, is difficult to judge since it reflects a mean time between failures of 18 to 24 months depending on the system. While there have been failures in less than 18 months, the majority of the data are usable and no decisions are being made on the raw data that is being transmitted via telemetry.
The meteorological station at TPM-1 has not failed and reports regularly, thus it maintains a high level of reliability. The rain gauges at the other sites have less complete data and thus have a lower reliability.
Maintainability Maintainability is the ease with which a component or equipment can be modified to correct faults. The quality guideline per the QAPP for completion of repairs to components or equipment is 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Given the size of the system, remote locations of some stations, and the occasional need for extended troubleshooting efforts, strict compliance with the guideline is not always possible or even appropriate. The automated groundwater and surface water stations (inshore) are easier to maintain than some of the other systems, however, some of the oscillation and daily reporting issues have required extensive troubleshooting. On at least a weekly basis, FPL checks for any automated groundwater and surface water stations that are on telemetry but are not reporting. Often the lack of reporting is related to low signal strength or loss of telephone connection the previous day and not to an equipment malfunction. Usually, the system will eventually report. Also on a regular basis, FPL looks at time series plots of the data to see if there are any unusual data trends or oscillations requiring troubleshooting and repair efforts.
The CCS flow meters are more difficult to maintain since they are the most sophisticated pieces of equipment and are affected by the harshest conditions. Rarely can the meters or the associated infrastructure be repaired in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. FPL suggests modifying the maintainability goal in the QAPP to take logistical constraints and other realities more into account.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Timeliness Timeliness is the promptness of reporting a measurement after it is made, reporting deficiencies, submission of reports or other project documentation, addressing corrective actions, and reporting deviations within the timeframes specified in the QAPP or within the Monitoring Plan or Agreement.
Per the QAPP, the analytical data have been consistently provided to the Agencies within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> following FPLs receipt of the data from the laboratory. While much of the data from the primary laboratory is in ADaPT format, such data has not undergone a full QA/QC review at the time it is submitted to the laboratory. Since the samples are analyzed by various laboratories, the results are received at different times with several of the isotope results (notably strontium and tritium) taking the longest to obtain. Once all sample results are obtained for a sampling event, a full QA/QC check of the data is conducted and FPL generates DUS Reports. The data are also further assessed during the preparation of semi-annual and annual reports; occasionally, suspect results are found and subsequently qualified.
The automated systems are currently set to report values at 15-minute intervals and, for those systems on telemetry, to upload the results daily. As previously discussed, low signal strength or other issues have prevented various telemetry units to consistently report every day. While the raw data can be viewed by the Agencies in FPLs electronic database, the data are not official until FPL has conducted a full QA/QC review.
If additional errors are noted in the data following the QA/QC process, the results are updated in the database or DUS, as applicable, and are included in an errata or the subsequent annual report.
Reports have been submitted to the Agencies per the timeframes outlined in the QAPP or in accordance with revised schedules agreed to by the Agencies.
Once there is concurrence that corrective actions from field and laboratory audits are needed, corrective action is typically implemented immediately or by the next sampling event.

- 2. AUTOMATED DATA COLLECTION 2.1 Groundwater Quality 2.1.1 Instrumentation and Data Collection Methods Automated groundwater monitoring stations were installed at 14 well clusters in a total of 42 wells (three wells per cluster) from February 2010 to August 2010. In each well, two probes manufactured by In-Situ, Inc. (an Aqua TROLL 100 [AT100] and a Level TROLL 500
[LT500]) were deployed primarily between June 2010 and September 2010 and were set to record water quality parameters and water levels, respectively, at 15-minute intervals. The probes were connected by cable to a telemetry unit and the data at each of these sites are transmitted remotely by cellular phone service to a central database once per day. The telemetry units are powered with 12-volt batteries that are recharged by solar panels. Figure 2.1-1 shows an automated groundwater station with telemetry.
The focus of this subsection is on the AT100 probe that measures groundwater quality parameters. The AT100 has a titanium body with a completely sealed, internal lithium battery, a real-time clock, a datalogger, and temperature and conductance sensors. At each well, an AT100 is placed in the middle of the screened well interval and measures actual conductance (microSiemens per centimeter [S/cm]) and temperature (degrees Celsius [°C]). This probe also calculates specific conductance, salinity, TDS, and water density. Salinity values are calculated using actual conductance and temperature and are reported in practical salinity units (per Practical Salinity Scale 1978 [PSS-78]). TDS is based on actual conductance with a manufacturer automated default conversion factor of 0.65, and results are reported in milligrams/liter (mg/L). Water density is calculated using salinity and temperature, and results are reported in grams per cubic centimeter (g/cm3).
Per the QAPP, the ideal cleaning and calibration schedule for the groundwater probes is approximately every eight weeks, with the Biscayne Bay probes on a rotation of approximately every six weeks. The actual schedule varies depending on field conditions and logistics.
For the cleaning and calibration efforts, probes are pulled from each well and the accuracy of the specific conductance and temperature readings are verified. For specific conductance, each AT100 is placed in a container with a known conductance solution near the expected sample value and Continuing Calibration Verification (CCV) performed. The reading on the probe and the value of the specific conductance solution is recorded. A value within 5% of the standard solution is considered acceptable; if the probes reading falls outside the 5% range, data from the previous calibration event up to the present reading are qualified as estimated (E) or questionable
(?) as discussed later in this section. Following the CCV, the probes are cleaned with analyte-2-1
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 free water and a non-abrasive cloth or sponge. Sensor heads are cleaned using cotton swabs or soft pipe cleaners.
Following the CCV, an initial calibration (IC) and an initial calibration verification (ICV) are conducted with a solution at the high end of the expected sample range. The AT100 and Aqua Troll 200 (AT200) use a single-point calibration equation. If the specific conductance reading of the probe during the IC and the value of the calibration solution is between 0.98 to 1.02 of each other (referred to as the cell constant), the reading is considered ideal, but a higher range between 0.90 and 1.10 is acceptable. Following cleaning and a successful IC, an ICV and two additional bracketing ICVs are done with standard conductance solutions, with one typically above and another typically below the expected sample value range, to bracket the range of readings. If a probe specific conductivity reading is outside of the acceptable range during any of the steps described above, the probe is replaced.
For temperature, each AT100 is verified during each cleaning and calibration event using a National Institute of Standards and Technology (NIST)-certified thermometer. The temperature reading of the probe is considered acceptable if it is within +/-0.5°C of the NIST thermometer reading. If a probe temperature reading is outside the acceptable range, it is replaced with another probe.
During cleaning and calibration, operational parameters involving general system functionality are addressed. The external battery voltage that powers the telemetry system (12:00 a.m. to 1:00 a.m. and 12:00 p.m. to 1:00 p.m. each day) is checked. The 12-volt batteries and solar panels are inspected, as well as fuses and wiring connections. In addition, internal voltage and memory availability of all probes are checked. Desiccants in the system are replaced during every cleaning and calibration event, and overall cleanliness is maintained. Inoperable equipment is repaired or replaced. In the event that equipment is vandalized, it is replaced.
In addition to routine cleaning/calibration, all probes are sent for factory calibration/maintenance checks approximately once every 18 months. This effort was conducted systematically from November 2011 through March 2012. If the cleaning and calibration event occurs when a probe needs to be sent for factory maintenance, the probe undergoes a CCV and high and low ICVs first to determine if it reads within the acceptable 5% range. When a probe is sent back to the factory for recalibration, another probe that has been factory-calibrated within the past 18 months is installed in its place. Since a replacement probe would not have recorded data prior to the current calibration, it would undergo only the IC, ICV, and high and low ICVs.
From June 2010 through June 2012, the most problematic issue with the automated stations continued to be the inconsistent daily reporting by the telemetry units. In nearly all cases, the data were recorded and stored in the instrument but, due to intermittent connectivity to the network, the data were not always transmitted to the FPL database on a daily basis. In a few cases, data were lost due to lightning strikes or probe electronic resets. If the system does not reconnect after these connectivity failures, FPL has to download and manually patch in the data.
Data are downloaded from probes every calibration event, typically during cleaning and 2-2
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 calibration events. High-gain antennas are now installed at most sites. Also, several issues are causing oscillations in some of the specific conductance values. These issues are discussed in the following subsections.
2.1.2 Results and Discussion All raw data are made available to the Agencies upon receipt by FPL and are subsequently reviewed for accuracy. Depending upon the results, some of the data are qualified using the qualification codes outlined in the QAPP. The validation and qualification of the data are a substantial undertaking and will continue to be so in the future. For example, each groundwater well (one AT100 and one LT500) generates 576 data points each day. This results in 24,192 data points generated by the groundwater stations (42 wells) each day or approximately 8,830,080 points annually. Both the surface and groundwater stations generate approximately 16.5 million data points per year.
Data validation and qualification is a multi-step process. The first step begins with the plotting of key water quality parameters (salinity, specific conductance, and temperature) over a set validation period as well as the entire period of record. This allows a quick review of the results and identification/flagging of data that are outside expected ranges. Any evident aberrations in the resulting time series plots are then reviewed further based on specific station location, meteorological conditions, and previous results.
As a second step, the data are then compared to validation and calibration logs to ensure that the probes are recording data within the tolerances (5% for specific conductance and 0.5°C for temperature). Data within the accepted levels are deemed valid and data outside that range are qualified. For specific conductance ICVs, most probes have been verified successfully; however, some of the data have been qualified primarily due to CCVs outside acceptable levels.
Nine probes have been out of range for temperature and 25 probes have been out of range for specific conductance, resulting in the qualification of data back to the time the probes last passed verification for that parameter. Most of the out-of-range data was qualified as estimated. The calibration and verification logs for the automated station probes are included in Appendix B.
In the final step, each data point for specific conductance, salinity, and temperature is compared to its previous 15-minute value to check for any unusual oscillations that may not have been caught during the calibration and verification events. Salinity differences greater than or equal to
() 1 practical salinity unit (per PSS-78) and temperature changes 1°C that occur within 15-minute intervals are flagged, and both data rows are highlighted. Data are then manually reviewed for validity. Flagged data are compared against meteorological data and other station data to help determine if they are real or spurious observations beyond normal parameters. There have been instances when a probe has exhibited extreme 15-minute oscillations (e.g.,
fluctuations up to 80,000 S/cm) for a period of time before resuming function within normal ranges. Other examples of spurious data include occurrences of specific conductance values dropping drastically and instantaneously and remaining at low levels for days to weeks, or oscillating for one or two time intervals before instantaneously returning to original levels.
2-3
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 Once the above steps are completed and all flagged data are reviewed, the data are qualified as appropriate. The qualifiers used in the data qualification effort are E indicating an estimated value, ? indicating suspect or questionable data, G indicating a recalculated value, and C indicating a calibration event. Data dependent upon other parameters, (i.e., specific conductance, salinity, density, and TDS) are also qualified for the corresponding period when these parameters are interrelated.
The E (estimated) qualifier has been added to data that oscillate, but not more than 5% from what is believed to be the actual value, due to a system electrical/radio frequency issue. Data from the previous cleaning and calibration event up to present are also qualified as E when an CCV ranges from 5% to 30%, or when verification or bracketing is not performed. For example, when In-Situ, Inc. deployed probes without performing verification (other than what was done at the factory), these data were qualified with an E.
The ? qualifier has been applied to data that should not be included in any analyses because they may not be an accurate depiction of actual field conditions. These include, but are not limited to, the following:
Data from any probe with an CCV greater than 30%; however, no data have yet to be qualified as questionable for this reason; Specific conductance values that erroneously oscillate between high and low readings at 15-minute intervals due to problems with the automated system; or Specific conductance, temperature, and water levels artificially altered when the probe is pulled for cleaning and calibration.
During cleaning and calibration events, both ? and C qualifiers are applied to all applicable parameters. The calibration event begins when a probe starts to be retrieved and ends when it has been set back in place and the temperature reading has stabilized. When air and water temperatures differ greatly, it can take the probe temperature several hours to return to accurate readings of ambient water temperature and, thus, all values are affected.
After a review of the key parameters in their entirety by a second QA/QC person, all qualified data from each station are validated on the EDMS and, subsequently, become available for download by the Agencies.
FPL has made refinements in the data qualification and validation process during the monitoring period and, when necessary, has retroactively applied qualifiers to previous sets of data. For example, in the last Semi-Annual Monitoring Report (FPL 2012a), FPL noted that, during a few short periods, the surface water levels exceeded the top of several groundwater well casings. The groundwater levels were qualified. Also, the water quality readings in several of the wells appeared to be slightly affected during sampling events and the data were qualified. FPL went back through all the previous data to determine whether similar events occurred and qualified the 2-4
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 data as appropriate. These changes only affect a small percentage of the data. The information presented in this report reflects the most current data set.
Only a small percentage of the water quality data has been qualified as questionable. The principal reason for using the ? qualifier is erroneous oscillating specific conductance values (greater than 5% over a 15-minute interval due to obvious system malfunction). An In-Situ, Inc.
representative initially stated that these abnormal fluctuations could have been caused by air bubbles on the sensor or by blocked sensor heads. However, gently shaking and tapping the probes have not necessarily alleviated this issue in every instance. FPL subsequently re-grounded some of the sites in hopes of rectifying the problem; however, oscillations were not completely eliminated. In-Situ, Inc. was able to reproduce the oscillation in the laboratory using high-frequency radio waves. These radio waves in the laboratory caused the probe cables to resonate, which caused fluctuating specific conductance readings. In-Situ, Inc. subsequently installed ferrite beads on the probe cables to eliminate cable resonance, but data oscillations still occurred, on occasion. While the oscillations appear to be less frequent than at the projects onset, it is still believed that other factors are contributing to the oscillations; therefore, testing has continued in order to determine the underlying causes of these patterns. One of the latest tests, implemented in January 2012, disconnected external power from several of the probes showing the most frequent oscillations. To date, these probes have been disconnected from the 12-volt battery (but remain connected to the telemetry system) and have been powered by the internal 1.5-volt lithium battery and, for a while, the data appeared stable. FPL has recently run new ground wires at TPGW-1 and TPGW-13, placed ferrite beads on the cables at those sites, and connected an additional grounding rod to TPGW-1, but oscillations in specific conductance still occurs. It appears this may be an ongoing issue; the associated data will continue to be qualified as questionable.
Figures 2.1-2 through 2.1-15 illustrate time series graphs of specific conductance, temperature, and salinity at each well. These graphs depict validated data and exclude suspect data that have been qualified as questionable or that were recorded during a calibration event. Appendix D provides time series graphs of these three parameters, with all reported data including questionable data. The time series graphs show data from the beginning of station reporting in 2010 (June through September 2010 depending on station) through June 2012. To facilitate closer review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data in separate Excel files with the report.
Tables 2.1-1, 2.1-2, and 2.1-3 show statistical summaries for time series specific conductance, temperature, and salinity data, respectively. The tables include monthly average values for each monitoring well and the minimum, maximum, average and standard deviation for the entire monitoring period; these summaries were calculated where at least 21 days of data were available for that month. The salinity values are presented since lay people often relate more directly to salinity than specific conductance. Figures 2.1-16, 2.1-17, and 2.1-18 show the average value and standard deviation for specific conductance, temperature, and salinity, 2-5
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 respectively, to facilitate a spatial visualization of the average automated groundwater results.
Statistical files have been included in separate Excel files with the report.
Overall, the qualified groundwater specific conductance and salinity data indicated consistent readings throughout the entire monitoring period. The salinity results track the specific conductance results since salinity is calculated based on specific conductance and temperature.
No observable seasonal changes occurred in any well location. Nearly all the specific conductance time series plots exhibit very little change over time. TPGW-1S was the notable exception where the specific conductance values ranged from approximately 48,000 µS/cm to 64,000 µS/cm.
Similar to what has been previously observed, the wells closest to the CCS and Biscayne Bay had higher specific conductance than the wells located farther away. Outer well clusters TPGW-7, TPGW-8 (excluding TPGW-8S), and TPGW-9 have groundwater that can be characterized as freshwater and do not appear to be affected by salt water intrusion. As discussed further in Section 3, TPGW-8S had specific conductance values that ranged from 2,067 µS/cm to 3,681
µS/cm, but ionic data indicated non-marine influences. Wells TPGW-4S, TPGW-5S, and TPGW-6S had average specific conductance values over the monitoring period of 2,163 µS/cm, 1,298 µS/cm and 1,127 µS/cm, respectively. All other wells are saltier and are influenced by marine water. Monitoring wells TPGW-1M, TPGW-1D, TPGW-2S, TPGW-2M, TPGW-2D, TPGW-3S, TPGW-3M, TPGW-3D, TPGW-12M, TPGW-12D, TPGW-13S, TPGW-13M, and TPGW-13D have the saltiest water, with specific conductance values consistently in excess of 60,000 µS/cm. The specific conductance values in well cluster TPGW-13 were the highest with average values in excess of 80,000 µS/cm.
The majority of the wells that appear to be influenced by marine water had higher specific conductance values with depth; however, the intermediate zone often exhibits values similar to the deep zone. Well cluster TPGW-13 is one of the exceptions where the average values over the monitoring period were slightly higher in the shallow zone, but the values between all zones were within 5% of each other. This is not unexpected at TPGW-13 given the hypersaline conditions in the CCS.
The groundwater temperatures in the intermediate and deep zones exhibited little to no change over the monitoring period and most appear flat-lined on the time series plots. The temperatures in the shallow zone wells were steady, but reflected minor seasonal influences; groundwater temperatures were typically higher near the end/beginning of the year and decreased to their lowest levels when air temperatures were warmer, which is the opposite of what would be expected if there was an immediate response in groundwater temperature to air temperature.
This trend may be reflective of a lag in the response of the shallow groundwater (20 to 40 ft below ground surface) to winter and summer air and surface water temperatures. The highest groundwater temperatures occurred in well cluster TPGW-13 with an average value over the monitoring period of 30.0°C. By comparison, the average groundwater temperatures over the monitoring period in TPGW-10S (Biscayne Bay well), TPGW-1S (near CCS), and TPGW-9S (westernmost well) were 26.1, 25.6, and 24.7°C, respectively. The average groundwater 2-6
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 temperatures in nearly all the wells were less than the average value of 26.1°C measured at both TPGW10S and TPGW-11S in Biscayne Bay. Wells TPGW-14M and TPGW-14D had slightly higher groundwater temperatures of 26.2 and 26.4°C. Well cluster TPGW-2 had average groundwater temperatures that ranged from 26.5 to 27.4°C, which could suggest some effects of the CCS. Well cluster TPGW-2 did not follow the same general groundwater temperature trends exhibited by the other well clusters, indicating some external influence.
To assess differences between wells over time, Figures 2.1-19 through 2.1-25 show comparisons of specific conductance and temperature in shallow and deep interval wells. Figure 2.1-19 shows that for the wells in Biscayne Bay, TPGW-14 has the highest specific conductance values and the highest temperatures at depth. Figures 2.1-20 through 2.1-23 show changes across the landscape and include wells in Biscayne Bay, the CCS, and wells farther inland. The figures illustrate how much higher the specific conductance and temperature are in CCS well cluster TPGW-13 than the other wells. Also, the figures show how the values generally decrease in wells with distance from the coast. Figure 2.1-24 shows plots of wells in close proximity to the CCS. Figure 2.1-25 compares Biscayne Bay surface water specific conductance values and temperatures with Biscayne Bay groundwater specific conductance values and temperatures. The plots show how much less the groundwater specific conductance values and temperatures fluctuate than the surface water values. This indicates the buffering effects that groundwater has on surface water changes.
2.2 SURFACE WATER QUALITY 2.2.1 Instrumentation and Data Collection Methods Automated surface water quality stations were located throughout the Turkey Point landscape as determined jointly with the Agencies. All stations record water quality and stage data at 15-minute intervals, with the exception of Biscayne Bay stations TPBBSW-1, TPBBSW-2, TPBBSW-4, and TPBBSW-5 which record only water quality parameters. While most sites that record surface water data have two probes (top and bottom), some have only one probe, depending on surface water depth and other logistical considerations. Stations that are in less than 3 ft of water have only one AT200 probe. Surface water quality stations with two probes have an AT100 at approximately 1 ft above the bottom and an AT200 within 3 ft of the surface.
The AT200 is similar to the AT100, except the AT200 also measures water stage. Similar to the AT100, the AT200 has a titanium body with a completely sealed internal lithium battery, real-time clock, data logger, and pressure, temperature, and conductance sensors. The AT200 is also programmed to auto-correct water levels for water density based on readings recorded by the probe. This feature is explained in greater detail in Section 2.3.1.
Similar to the groundwater sites, probe cables are attached to a telemetry system that uploads once a day for most sites (Figure 2.2-1). Table 2.2-1 summarizes the probes used at each surface water station and the parameters measured. Currently, 33 probes (AT100s and AT200s) are deployed throughout the monitoring area, generating up to 6.3 million data points each year.
2-7
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 Four of the automated surface water quality sites in Biscayne Bay (TPBBSW-1, TPBBSW-2, TPBBSW-4, and TPBBSW-5) are not connected to a telemetry system for logistical reasons. Per the Monitoring Plan, these probes are set up similar to the BNP salinity monitoring network stations (Biscayne National Park 2007) equipped with probes that record specific conductance just above the sediment surface. Rather than installing platforms or pilings, the probes are firmly attached to a cement paver/pad and are placed at pre-determined locations on the Bay bottom.
Since these probes are designated to measure only water quality parameters, AT100s are deployed at each of these four locations. The probes are swapped out approximately every six weeks, returned to the field office where they are cleaned and calibrated, and the data are manually uploaded into the online database.
All AT100 and AT200 probes are cleaned and calibrated using the same methodology as described for groundwater sites. Appendix B shows the water quality field verification/
calibration logs. Additional verification measurements are conducted for the water level measurements associated with the AT200, as detailed in Section 2.3.1.
2.2.2 Results and Discussion The automated surface water quality data are qualified and validated in the same manner as the automated groundwater data. Figures 2.2-2 to 2.2-23 show time series graphs of specific conductance, temperature, and salinity at each surface water station. These graphs depict validated data and exclude suspect data that have been qualified as questionable (?), estimated (E), or qualified due to impacts during a calibration (C) event. Appendix C shows what data were qualified, while Appendix D shows time series graphs of the three parameters, but with all reported data including suspect data. The time series graphs show data from the beginning of station reporting in 2010 (August or September 2010, depending on station) through June 2012.
Note that the salinity results for all the surface water stations track the specific conductance results since salinity is calculated based on specific conductance and temperature, thus most of the discussion focuses on specific conductance and temperature. To facilitate closer review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data files in separate Excel files with the report.
Tables 2.2-1, 2.2-2, and 2.2-3 show statistical summaries of the time series data for specific conductance, temperature, and salinity, respectively. The tables include monthly average values for each monitoring station and the minimum, maximum, average and standard deviation for the entire monitoring period. The salinity values are presented since lay people often relate more directly to salinity than specific conductance. Figures 2.2-24, 2.2-25, and 2.2-26 show the average value and standard deviation for specific conductance, temperature, and salinity, respectively, to facilitate a spatial visualization of the average automated surface water results.
Statistical files have been included in separate Excel files with the report.
Compared to the groundwater time series graphs, the surface water time series graphs show greater variability in the data, most of which is related to seasonal and meteorological conditions.
2-8
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 For example, in Biscayne Bay, the highest specific conductance values are near the end of the dry season and the lowest values are near the end of the wet season with minimum and maximum values ranging from 18,922 µS/cm (TPBBSW-10B) to 66,884 µS/cm (TPBBSW-1B).
The highest values in Biscayne Bay were recorded near the end of the very dry season in June 2011 at six of the seven Biscayne Bay stations. This equates to salinities throughout the project area in excess of 40 units on the practical salinity units (PSU) scale. Figure 2.2-27 compares surface water specific conductance values at Biscayne Bay stations. Station TPBBSW-14B (measured near the surface) consistently has the lowest water temperatures while TPBBSW-10B (measured near the surface) has the most variability. The specific conductance values in Biscayne Bay are within ranges observed at BBCW10 (SFWMD well located several miles north). In some instances, for example much of June 2011 specific conductance values were higher at BBCW10 than at Turkey Point Biscayne Bay stations.
The specific conductance values in the CCS show less seasonal variability than Biscayne Bay, but do change in response to rainfall events. Following a high rainfall event on October 8, 2011 (6.33 inches measured at TPM-1), the specific conductance values dropped 10% to 20% at all stations. This is similar to what occurred the previous year in September and November 2010 following several heavy rain events (7.34 and 4.36 inches, respectively, at TPM-1). The data show that there was no clear pattern of higher or lower specific conductance among the CCS stations. Variability in the results is often within the acceptable calibration limits of the instrument. Quarterly surface water sampling indicates the specific conductance values at all CCS stations are typically within 5% of each other. Over the entire monitoring period, the minimum and maximum CCS specific conductance values ranged from 50,528 µS/cm (TPSWCCS-4B) to 93,594 µS/cm (TPSWCCS-6B). The average specific conductance values in the CCS were consistently over 70,000 µS/cm in comparison to Biscayne Bay average values ranging between 43,433 µS/cm and 51,006 µS/cm for the monitoring period. Figure 2.2-28 compares time series specific conductance values between the CCS and several Biscayne Bay surface water stations. The specific conductance at TPSWC-5T is consistently higher than the Biscayne stations by over 20,000 µS/cm.
In the L-31E Canal stations, (TPSWC-1, TPSWC-2 and TPSWC-3), the specific conductance values were predominantly reflective of freshwater, however slightly more saline conditions were noted during several periods. The most notable period was near the end of the very dry season in June 2012 when maximum specific conductance values were 9,507 µS/cm (TPSWC-2B) and 22,776 µS/cm (TPSWC-3B). As is discussed in Section 3, there was not an incremental increase in tritium concentrations which might indicate regional Biscayne Bay influences instead of an influence from the CCS. Figure 2.2-29 compares time series specific conductance and temperature values for the different surface water stations in the L-31E Canal. Other spikes in specific conductance values were noted in TPSWC-3B in November 2011 and near the end of the dry season in 2012.
The specific conductance values in the two tidal stations TPSWC-4 and TPSWC-5 were more variable than the L-31E stations. TPSWC-4 is affected by releases from the S-20 structure and can transition from saline to fresh conditions quickly. Station TPSWC-5 reflects marine 2-9
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 conditions, but exhibited values in excess of those found in Biscayne Bay at the bottom. The water at TPSWC-5 is over 20 ft deep and is located at the end of this dead-end canal. The deep water depths and restrictions in flushing may contribute to the observed specific conductance values at this station.
The ID specific conductance values are affected by pumping of the ID ditch, which is conducted mostly in the dry season to maintain a seaward gradient between the L-31E Canal and the ID.
During non-pumping periods, the water in the ID is slightly saline to brackish, but during periods of heavy pumping, the water becomes saline in the pumped segments. In June 2011, the specific conductance values reached a peak at two ID stations with values in excess of 55,000 S/cm.
The effect was most pronounced at the bottom of TPSWID-2 where specific conductance values remained the highest for the longest duration. Specific conductance values in the ID were always below the values in the CCS and reflect a mixing of CCS water, freshwater, and Biscayne Bay water. Figure 2.2-30 compares time series specific conductance and temperature values for the different surface water stations in the ID. Figures 2.2-31 through 2.2-33 compare time series specific conductance and temperature values for the ID, L-31E, and CCS, at ID operation transect A stations (TPSWID-1, TPSWC-1, and TPSWCCS-1), transect C stations (TPSWID-2, TPSWC-2, and TPSWCCS-7), and transect E stations (TPSWID-3, TPSWC-3, and TPSWCCS-3), respectively. The figures show that CCS specific conductance values are highest in the CCS and lowest in the L-31E. The figures also show the temperature difference between the water bodies as the CCS cools from transect A to transect C. Discussion of the ID operation is included Section 6 of this report.
Water temperatures at all stations are greatly affected by meteorological conditions and reflect seasonal trends as expected. Ambient air temperature changes were quickly reflected in water temperatures and both Biscayne Bay and CCS stations tracked closely the overall ambient trend (Figure 2.2-34). In Biscayne Bay, average monthly water temperatures in January 2011 were around 20°C at all stations. In July 2011, average monthly water temperatures were near 31°C at all Biscayne Bay stations and the highest recorded 15-minute temperature was 35.2°C at TPBBSW-10B.
The water temperatures in the CCS also change with air temperature but are higher than other surface water locations. The CCS water is pumped from the intake side of the plant and routed through condensers to cool the power units. As the water passes through the condensers, it is heated and eventually discharged on the west side of the plant back into the CCS. The water temperatures on the CCS discharge side of the plant at TPSWCCS-1B are 7.5°C warmer on average for the entire monitoring period (June 20110 through June 2012) than at the intake side of the plant at TPSWCCS-6B. The range in temperatures varies monthly and CCS surface water temperatures are warmer in the summer months and cooler in the winter months. For example in September 2011, the average monthly CCS water temperatures ranged from 31.9°C at TPSWCCS-6B to 40.1°C at TPSWCCS-1. In January 2012, the average monthly CCS water temperatures ranged from 23.8°C at TPSWCCS-6B to 33.1°C at TPSWCCS-1B. There did not appear to be any temperature stratification at TPSWCCS-4 and TPSWCCS-6 since the water temperature was consistently the same at the top and bottom. However, at TPSWCCS-5, the 2-10
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 surface water temperatures were consistently higher at the top station. Figure 2.2-35 shows time series plots for stations in the CCS and illustrates the differences in temperature between stations on the discharge side of the plant (i.e., TPSWCCS-1B, TPSWCCS-7B) and the intake side of the plant (i.e., TPSWCCS-5 and TPSWCCS-6).
CSS water temperatures are regularly higher than the daily ambient air temperatures (Figure 2.2-34) and are often higher than daily maximum temperatures (Figure 2.2-36). This rarely occurs at other surface water stations. If there are temperature effects on Biscayne Bay from the warmer CCS waters, the effects would most likely be evident during the cooler months. Figure 2.2-36 shows the water temperatures from February to June 2011 for all the Biscayne Bay stations installed for the Uprate monitoring. Surface water temperatures from a SFWMD Biscayne Bay monitoring station several miles north of the site (BBCW-10) are included on Figure 2.2-36. The Turkey Point Biscayne Bay monitoring stations track very closely both with the SFWMD station and the maximum air temperatures recorded at TPM-1.
To help assess whether CCS water temperatures are affecting Biscayne Bay water temperatures, the differences between CCS and Biscayne Bay water temperatures and the differences between ambient air and Biscayne Bay water temperatures were examined (Figure 2.2-37). The results clearly demonstrate that CCS water temperatures, both on the intake and discharges sides, are warmer than Biscayne Bay water temperatures; there is only one instance where the plot exhibits a negative value for the difference between CCS and Biscayne Bay water temperatures (February 13, 2011; TPSWCCS TPBBSW4). This occurred when there was a major drop in the low ambient air temperature on February 13, and it appears the CCS water temperature responded more quickly to the daily low temperature. When compared to ambient air temperatures, Biscayne Bay water temperatures oscillate between being higher and lower than ambient air temperatures, particularly during the cooler months. This is to be expected as cold fronts move through and air temperatures both drop and recover more quickly, and to a greater degree, than water temperatures. Later in the year, mean ambient temperatures are almost exclusively lower than Biscayne Bay water temperatures. More importantly however, differences between the northern SFWMD surface water station (BBCW10) and both the ambient air temperatures and the CCS water temperatures follow the same pattern and are of the same magnitude as the FPL Biscayne Bay stations. These results suggest that air temperatures are driving water temperatures in Biscayne Bay and do not indicate any readily evident CCS water temperature effects in Biscayne Bay.
Water temperatures in the L-31E Canal (Figure 2.2-29) are on average cooler than those in Biscayne Bay. There is some temperature stratification in L-31 in part due to the canal depths and typically limited flow. The near surface water temperatures are almost always warmer than the bottom temperatures and the surface temperature exhibits more daily variability in response to air temperature changes. Near the end of the 2011 dry season, the bottom temperatures in TPSWC-3B were similar to the near surface water temperatures at that location and the timing coincides with the increase in specific conductance discussed above.
2-11
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 The time series plots (Figure 2.2-30) show that there were periods when the bottom water temperatures in the ID were greater than the surface water temperatures and those periods often corresponded with pumping of the ID and reflect some influence from the CCS. As a result, the average temperatures in the ID stations are higher than at the L-31E stations based on the entire monitoring period.
The water temperatures in the two tidal canal stations (TPSWC-4 and TPSWC-5) were also affected by air temperatures, but TPSWC-4 was also affected by discharges from S-20.
Generally the surface water temperatures at TPSWC-4 were higher than or similar to the bottom water temperatures; the effects of the CCS, if any, were hard to differentiate due to the variables that could affect water temperature. At TPSWC-5, the bottom water temperature was higher than the surface water temperature for months at a time.
2.3 WATER LEVELS 2.3.1 Instrumentation and Data Collection Methods Water levels provide insight into groundwater hydrology and groundwater and surface water interactions; levels are collected at all groundwater and most surface water stations for the Uprate Project monitoring effort. Only four water quality stations in Biscayne Bay do not have stage recorders. Per the Monitoring Plan, automated surface water quality monitoring stations co-located with groundwater monitoring well clusters in Biscayne Bay were to have surface water stage recorders. During the siting of the wells and surface water stations in Biscayne Bay, only one surface water quality station (TPBBSW-3) was co-located with a well cluster (TPGW-11); thus, one stage recorder was initially installed in Biscayne Bay. FPL later opted to install two additional stage recorders in Biscayne Bay (one each at the platforms associated with TPGW-10 and TPGW-14) to better assess groundwater and surface water interactions and tidal differences across the landscape.
Water pressures are measured at 15-minute intervals, and water levels are calculated from the pressure data. The results are typically transmitted on a regular basis via telemetry. LT500 and AT200 probes are used to record water pressure/levels. The LT500 only measures water pressure and temperature. This probe model is used in all automated groundwater well sites and is co-located with AT100 water quality units, but is placed near the surface to increase the accuracy of the pressure readings. At all automated surface water stations, AT200 probes are used for water levels since the probes measure both water pressure and water quality parameters. Both types of data are needed for surface water stations, and probes can typically be placed within 3 ft of the surface. Both probe models that measure water pressure have been deployed using a vented cable. The vented cable contains a tube that applies atmospheric pressure to the back of the pressure gauge. The instrument is programmed to automatically subtract this value from the measured pressure, reflected in the following formula:
Pgauge = Pabsolute - Patmosphere 2-12
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 Aside from being able to measure water quality parameters, the biggest difference between the AT200 probe and the LT500 probe is how specific gravity (SG) is handled. In the AT200 probe, an option exists to program a fixed density value or to auto-adjust water levels based on actual measured density. In the LT500 probe, only a fixed density value can be entered based on the water type (freshwater, brackish water, or saltwater). All LT500 probes are individually set to the fixed density value that best characterizes the water in the well. The AT200 probes are programed to automatically adjust water levels based on the measured density.
Both probes are programmed to record water levels based on a depth-to-water level setting.
Water levels are calculated in the instruments from the measured pressure based on the following formula:
WL = RL + (2.31 * (RP-MP)/SG) where:
WL - water level (measured in feet based on the North American Vertical Datum of 1988 (ft NAVD 88)
RL - reference water level (ft NAVD 88)
RP - reference pressure (pounds per square inch [psi])
MP - measured pressure (psi)
SG - specific gravity (unitless)
The SG in the above formula is the same as the density reading; thus, the values come directly from the instrument.
The reference level (RL) is a key component and is established in the field by using a water level indicator to measure the depth to water from the top of the well casing. Since the top of casing has been surveyed to an established datum (both NAVD 88 and National Geodetic Vertical Datum of 1929 [NGVD 29]), an elevation of the water is quickly determined by subtracting the depth to water from the top of casing. The resulting water level elevation is then entered into the probe as the reference level. The probe then automatically calculates the related pressure value, referred to as the reference pressure (RP). Subsequent pressure measurements recorded by the probe are relative to the reference pressure and its associated elevation.
The AT200 probes are cleaned in the same manner as described for the AT100 probes in the previous sections. The LT500 probes are wiped down with analyte-free water, with care not to damage the pressure transducer. The same care is used on the AT200 probes. While the pressure sensor cannot be calibrated, the resulting stage readings are verified. FPL has refined their approach over the course of the monitoring effort to improve the accuracy of the data. Currently, water level measurements are taken with a water level indicator prior to the removal of the LT500/AT200 probes for cleaning. An instantaneous reading from the probe is taken and compared to the water level indicator. Readings differing less than 0.1 ft are considered acceptable. The probe is then removed for cleaning, placed back in the well, and a similar comparison is made with the water level indicator and pressure reading. If needed, the reference 2-13
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 level is reset so the probe reading matches the water level reading to within 0.03 ft, which is the accuracy of the pressure sensor.
Similar to the AT100 probes, all LT500 and AT200 probes are factory-calibrated every 12 to 18 months. This effort was conducted systematically during regularly scheduled cleaning and calibration events between November 2011 and March 2012.
2.3.2 Results and Discussion 2.3.2.1 Groundwater As part of the validation process, water levels and pressures were plotted for the entire time period for each station. Sudden changes in water level were identified and checked against stage changes at other stations and against rainfall measurements. Time series plots of water levels in similar media and areas such as the CCS or in Biscayne Bay surface water were overlain and compared to one another to help identify potential problems with water level results. In addition, plots in groundwater and nearby or an overlying surface water body were overlain for similar comparisons. Careful attention was paid to periods when cleaning and calibration events occurred and for any activity that could alter the probe placement. Where stage data were available from a water level indicator or stage gauge readings, those values were compared to the reported water level measurements.
If water levels reported by the probe and field-measured values were off by more than 0.1 ft, the data were flagged for closer inspection. Also, shifts in data immediately following a calibration event or activity that could have impacted the probe placement were flagged if they were greater than 0.1 ft. The flagged data were reviewed further and, in some instances, it was clear there was an issue with an incorrect reference level and the data were corrected. In some instances, the cause for a discrepancy greater than 0.1 ft could not be established and the data were qualified as estimated; in other cases, the results were highly suspect in consideration of historical and surrounding station results, and the data were qualified as questionable. For difference of less than 0.1 ft, no correction or qualification of the data was applied.
It should be mentioned that the accuracy of the land-based station survey is better than 0.1 ft (typically within hundredths of a foot), but well locations in the Bay may have a lower level of accuracy since those stations could only be surveyed with GPS units. Thus, the survey accuracy limits should be taken into account when interpreting the results to hundredths of a foot or, in the case of the Biscayne Bay wells, to several tenths of a foot.
Figures 2.3-1 through 2.3-14 show time series graphs at all automated groundwater stations.
These graphs are based on refined validated data and exclude data that are questionable or recorded during a calibration event. Stage data were typically not qualified if the density values were suspect since the differences in the instrument-calculated density had little effect on the pressure reading/stage results, given the shallow depth of probe placement. All time-series graphs are based on actual measured levels, with the probes set to a representative density setting. The values do not reflect freshwater head equivalents. In order to facilitate closer 2-14
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data files in separate files in Excel with the report.
Some of the water level data reported in the first Semi-Annual Report (FPL 2011a) were revised based on a resurvey of the top of casing of groundwater wells. This updated information was included in an Errata to the 2011 Semi-Annual Report and changes were reflected in subsequent reports. Also for the first reporting period, FPL initially conducted a post-correction calculation to adjust the LT500 readings from a fixed density value to a measured value using the density from the AT100 located in the same well at depth. This post-correction used the above formula and was calculated similar to how an AT200 is programmed to calculate water levels. FPL subsequently determined (with SFWMD concurrence) that this procedure was unnecessary as the LT500 water levels readings were only affected by a few thousandths of a foot given the shallow placement of the LT500 probes. All water level data reported in the first Semi-Annual Report (FPL 2011a) were slightly readjusted based on a set density representative of that well. These adjustments have been reflected in subsequent reports.
A summary of the data collected and the patterns observed follows:
Water levels change very quickly in response to rainfall events. This is most evident in stations not significantly influenced by tides (TPGW-1, TPGW-2, TPGW-4 through TPGW-9, and TPGW-13). Typically, wherever there is a spike in water levels on the time series graphs, there is a corresponding rainfall event. Refer to Figures 2.3-1, 2.3-2, and 2.3-4 through 2.3-9 and 2.3-13.
At each well cluster, fluctuations in stage for all three depth intervals track closely, indicating a good hydrologic connection between intervals.
Water levels at stations in or immediately adjacent to Biscayne Bay (TPGW-3, TPGW-10, TPGW-11, TPGW-12, and TPGW-14) exhibited tidal influence at all three depths (Figures 2.3-3, 2.3-10, 2.3-11, 2.3-12 and 2.3-14). The amplitude of the tidal changes decreases across the landscape from north to south, similar to the decrease in surface water tidal amplitude discussed below. Thus, TPGW-10 has a higher range of water levels than TPGW-14.
Stations furthest from the coast (TPGW-7, TPGW-8, and TPGW-9) exhibit few water level differences among the shallow, intermediate, and deep wells (Figures 2.3-7, 2.3-8 and 2.3-9). These wells are all fresh per FDEP standards.
Wells located between the westerly most wells and the CCS, such as TPGW-4 and TPGW-5, have brackish water in the intermediate and deep zones overlain by much fresher water in the shallow zone. The shallow zone water elevations in these wells are always higher than the deep zone (Figures 2.3-4 and 2.3-5).
Closer to Biscayne Bay and the CCS, several well clusters have deep or intermediate zones with the highest elevation, such as TPGW-2. At this cluster, the deep and intermediate interval water levels alternate between having higher water levels (Figure 2.3-2).
2-15
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 At TPGW-13, the shallow and intermediate zones have nearly identical water levels and the deep zone is up to 0.4 ft lower.
For the land-based stations (tidal and non-tidal), the groundwater levels ranged up to 3 ft over the monitoring period. The non-tidal inland stations had the greatest seasonal range since they are affected more by drought and rainfall conditions. The lowest groundwater elevations at all the land-based stations, with the exception of well cluster TPGW-13, were reported in late May and early June 2011. This was near the end of an extended very dry season. The lowest groundwater elevations at well cluster TPGW-13 were recorded about a month earlier. The previous semi-annual report noted that the water levels at TPGW-2 were the lowest in early May 2011, but further review of the data indicates that the groundwater levels were lowest at this cluster in late May/early June 2011.
To provide insight into the differences in groundwater water levels over the landscape, time series plots from select stations are illustrated on Figures 2.3-15 to 2.3-18. Each figure represents a transect of well clusters. Many of these figures are self-explanatory and support the discussion above. Note that the water elevations of the non-tidal stations in Figures 2.3-15 and 2.3-16 are higher than the tidal stations, with the notable exception towards the end of the very dry season between April and mid-June 2011. Also note that TPGW-13S groundwater elevations on Figures 2.3-17 and 2.3-18 typically follow along the upper range of the tidal stations. Care should be used in drawing conclusions about groundwater flow directions based solely on the transect water levels since density effects have to be considered. Basically, denser water has more driving head than freshwater, and groundwater flow is influenced by these density differences. All the times series data that are reported reflect actual measured water levels and have not been converted to freshwater head equivalents.
To provide some initial insight into the groundwater and surface water interactions, Figures 2.3-19 through 2.3-21 illustrate the differences between surface water levels and groundwater levels in a nearby or co-located well(s) and where the densities in most wells and surface water stations are somewhat similar. Figure 2.3-19 shows a time series plot of surface water stage at TPSWCCS-2 and TPGW-13S and TPGW-13M. The results indicate that the water elevations at TPGW-13S are higher more often than at the corresponding surface water station in the CCS (TPSWCCS-2). However, there was at least one extended period during the dry season of 2011 when the CCS surface water levels were higher.
Figure 2.3-20 shows surface water levels in the CCS and groundwater levels in several wells immediately to the west. Figure 2.3-21 shows daily average surface water levels in TPBBSW-3 and TPGW-11, which is in Biscayne Bay. The daily average eliminates the hourly tidal fluctuations and facilitates a visual comparison between these stations. The plot illustrates that the groundwater levels in the Bay stations are directly influenced by surface water stage and the groundwater elevation at TPGW-11S is always higher than the co-located surface water station.
Further discussion of the groundwater elevations and implications is provided in Section 5 of this report.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 2.3.2.2 Surface Water Figures 2.3-22 through 2.3-39 show time series graphs at all surface water stations where data from automated stage recorders are available. These graphs are based on validated data and exclude data that are questionable or recorded during a calibration event when the log was running. All the time series graphs are based on actual levels and do not reflect freshwater head equivalents. In order to facilitate closer review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data files in separate files in Excel with the report.
The precision and accuracy of the surface water levels, particularly associated with stations affected by wave activity, may be slightly lower than for groundwater stations. While wave activity is dampened in stilling wells, some oscillation occurs that can affect the ability to consistently get precise verification readings with a water level indicator. Some data end up being qualified as estimated since a verification reading is off by more than 0.1 ft when in reality it may not need to be qualified. Also, the setting of the reference levels is affected by waves and can cause readings to be off.
As expected, diurnal water level variations were observed at all tidal-influenced stations, including those located in Biscayne Bay (north to south: TPBBSW-10, TPBBSW-3, and TPBBSW-14), as well as tidal canal stations (TPSWC-4 and TPSWC-5). The tidal range declines across the landscape from north to south (Figure 2.3-40). At TPBBSW-10, tide ranges during spring tide and neap tides can be over 2.0 ft and less than 0.5 ft, respectively.
The effect of rainfall is masked in most tidal stations; however, its effect is evident at TPSWC-4 since this station is downstream of S-20 discharges. Rainfall effects are also evident on all onshore stations where water level increases up to 1 ft have been observed following significant rainfall events in L-31E, the CCS, and the ID.
Water levels in the CCS vary spatially depending upon whether the station is located on the discharge or intake side of the canal. Water levels on the plant discharge side have lower ranges in variability (<1 ft at TPSWCCS-1) than stations on the discharge side (up to 4 ft at TPSWCCS-6). Also, water levels on the discharge side of the CCS are typically at least 1 ft higher than those on the CCS plant intake side (Figure 2.3-41). The difference in stage between the discharge and intake side increased during the 2011 and 2012 dry seasons and decreased during the wet season. It was noted that the water levels at all stations were very similar in late September and October 2010, October 2011 and February 2012 following a heavy rainfall event.
Water levels in the CCS and L-31E exhibit little response to tidal influences in Biscayne Bay surface water. Figure 2.3-42 provides a representative time series plot for spring tides on December 24, 2011, and March 9, 2012, which shows the lack of tidal response in the CCS and L-31E. This suggests the hydrogeologic connection with Biscayne Bay is limited or not as direct.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 Figure 2.3-43 illustrates a transect of surface water levels, over the entire time period, that includes Biscayne Bay, the CCS, and the L-31E Canal. Care should be used in drawing conclusions about gradients solely based on the transect water levels since density effects have to be considered. Basically, denser water has more driving head than freshwater, and groundwater flow is influenced by these density differences. All the times series data that are reported reflect actual measured water levels and have not been converted to freshwater head equivalents.
To facilitate closer review of the time series results by the Agencies and allow them to adjust graphic scales and/or focus on a specific time interval, FPL has included the raw time series data files in Excel with the report. Further discussion of the surface water elevations and implications is provided in Section 5 of this report.
2.4 METEOROLOGICAL DATA One of the key parameters of interest is the amount of precipitation in the CCS and surrounding areas. Rainfall timing, duration, and amounts provide some insight into the areas hydrology.
Additionally, meteorological data such as barometric pressure, wind speed, and light levels (i.e.,
photosynthetically active radiation [PAR]) are useful in determining water losses and gains in the CCS and in establishing a water budget.
A meteorological station (TPM-1) was set up in the middle of the CCS, co-located with TPGW-13 and TPSWCCS-2. Four additional rainfall gauges were set up in the vicinity of the plant to determine the spatial and temporal variability in rainfall on and offshore Turkey Point Plant. Locations of the rainfall and the meteorological stations are shown on Figure 2.4-1 and photos are included in Figure 2.4-2.
2.4.1 Instrumentation and Data Collection Methods Meteorological station TPM-1 consists of a weather transmitter (WXT520, Vaisala Inc., Helsinki, Finland) and a quantum sensor (190SA, Li-Cor Inc., Lincoln, Nebraska) attached to a datalogger (CR1000, Campbell Scientific Ltd., Logan, Utah) and telemetry system, mounted 15 ft above the ground surface; the range of parameters measured is listed in Table 2.4-1. Technical specifications on the instrumentation are provided in Appendix I of the QAPP (approved 12/2/2011, FPL 2011).
The four rainfall-only stations (TPRF-2, TPRF-4, TPRF-11, and TPRF-12) consist of tipping bucket rainfall gauges (TB-3, Hydrological Services Inc., Liverpool, NSW, Australia) connected to waterproof pendant dataloggers (#UA-004-64, Onset Computer Corporation, Bourne, Massachusetts). Data are manually downloaded from these stations at approximately bi-monthly intervals. Rainfall data from the gauges are event-based. The tipping buckets fill at 0.10 inch and the time of each tip of the bucket is recorded.
Additional rainfall data for this report were also provided by a previously existing FPL meteorological station located south of the CCS by the Sea Dade Canal (LU-South) and from an 2-18
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 existing rainfall station in the northern portion of the CCS (LU-NEast). The FPL meteorological station (LU-South) is similarly instrumented with a weather station (Climatronics Corp.,
Bohemia, New York), while the rainfall collector (LU-NEast) is a tipping bucket gauge.
Monitoring at TPM-1 was initiated on July 26, 2010, while the rainfall gauges were installed on November 12, 2010. At TPM-1, data are set to record at 15-minute intervals, although a reconfiguration of the initial setup by the manufacturer resulted in 30-minute data recording until March 7, 2011; although no data were lost, the data logger was then reset to record at 15-minute intervals after March 7, 2011. Data collected at this station are uploaded via telemetry to the FPL database on a daily basis.
In the past, issues with TPRF-12 not recording data occurred, but the unit has since been rewired and is now functional. Additionally, several of the other stations ran out of memory and did not record a full time period of data. These issues have been resolved, but gaps in data from the rainfall gauges remain.
2.4.2 Results and Discussion Rainfall and temperature (Figure 2.4-3), relative humidity and barometric pressure (Figure 2.4-3), wind speed and wind direction (Figure 2.4-4), and PAR (Figure 2.4-5) for TPM-1 are shown for the entire period.
Over the 704 days of continuous recordkeeping, (July 27, 2010, to June 30, 2012), 121 inches of rain were observed at TPM-1 (Table 2.4-2). The greatest monthly rainfall totals were observed in September 2010 (13.5 inches), followed by October 2011 (13.3 inches), and April 2012 (12 inches) (Figure 2.4-6 and Table 2.4-3). There were a total of 430 rainfall days with 39 days having recorded totals in excess of 1 inch in a calendar day (Table 2.4-4). The number of rain-days and the amount of rainfall was generally greatest during the wet season (May to November), with the driest months from December to February. The least amounts of rain in a month were observed in February 2011 (0.2 inches), November 2011 (0.3 inches) and December 2010 (0.5 inches).
During the first 11 months of monitoring, a severe drought was observed across Florida in the early half of 2011, as evidenced by the limited precipitation (6.1 inches total) from February to May 2011. The second year of monitoring (July 2011 to June 2012) was less dry, as evidenced by the higher amount of rainfall (81 7 inches). These inter-annual differences in precipitation between years (3.8 inches per month from August 2010 to June 2011 water year versus 6.8 inches per month from July 2011 to June 2012) underscore how rainfall variability can potentially influence the hydrology and ecology in coastal South Florida.
Rainfall frequency and periodicity is tied to the seasonal patterns of low pressure over South Florida during the wet season and is a consequence of cold front passage during the winter months. For example, the highest daily precipitation amounts were observed on September 29, 2010 (7.3 inches), and October 8, 2011 (6.3 inches). Both these events are tied to the passage of 2-19
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 low pressure systems over South Florida. The passage of cold fronts is usually evidenced by a drop in barometric pressure during the early winter days. Typically, the passage of a cold front is accompanied by higher wind speeds and decreased relative humidity following the rain event.
An example of this is shown in late 2010 by the first significant cold front of that season which occurred from November 3 to 5, resulting in a significant decrease in temperature (about 10°C),
relative humidity, and pressure.
Table 2.4-3 shows monthly rainfall totals from other rainfall stations around TPM-1. Although there was some variability among stations, the monthly rainfall totals in Biscayne Bay are consistently less than those on land while the totals at TPM-1 are higher than at most stations for most of the period of record. Nonetheless, the patterns at all stations are generally consistent across the months at the stations measured.
Air temperatures (at 15 ft above ground) in the middle of the CCS at TPM-1 ranged from 2.8°C to 33.8°C for the period of record, with an average of 25.5°C. The minimum temperature was observed on December 14, 2010, during the morning hours of a cold front passing through the area. The warmest temperature was observed on July 11, 2011, as July through September (monthly average > 29°C) are usually the warmest months of the year. Comparatively, the winter months of 2010/2011 (November to February) were colder than the similar time period of the following year (Figure 2.4-3).
Relative humidity at TPM-1 was an average of 71% during the period of recordkeeping. The patterns, however, were more variable in the winter months compared to the warmer months of April through June. Diurnal humidity patterns were influenced by broader seasonal patterns; for example, continued rainfall over several days in late September 2010 resulted in a few days (September 28 to 30) of 90% humidity while the passage of cold fronts (e.g., December 15, 2010) resulted in a humidity drop from 75% to 21% in 3.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />.
The prevailing wind directions from July 2010 through June 2012 were from the east and east-southeast, i.e., predominantly onshore (Figure 2.4-7). Average wind speed for the whole period, at 5 meters above ground, was 10 miles per hour (mph). The lull wind speeds averaged 6 mph, but several instances of strong wind gusts were observed, some in excess of 60 mph. The highest wind speed recorded at TPM-1 was observed during the passage of a frontal boundary on October 13, 2011, when a 134 mph wind gust was recorded. Similarly, wind speeds > 60 mph were seen on July 13, 2011, and April 26, 2012, with the approach of storm fronts. Forty-four percent of the time, the winds were between 7 to 11 meters per second (Figure 2.4-8).
Light levels show seasonal amplitude, with maximum light levels during the summer months and decreased light levels during the wintertime. Despite these overall trends, there were smaller patterns of decreased light levels as a consequence of cold front events (e.g., October 6 to 20, 2010) where several days of continuous cloudiness resulted in lowered light levels (Figure 2.4-5).

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 2.5 CCS FLOW METER DATA 2.5.1 Instrumentation and Data Collection Methods As previously discussed in the August 2011 Annual Report (FPL 2011b), automated Acoustic Doppler Flow Meters (ADFMs) were initially installed at three constrained-flow locations in the CCS and are referred to as the outflow, southerly, and inflow stations. The outflow station (TPFM-1) was set up to measure outflow of water from the plant entering the CCS; due to the canal setup, the station was located in the discharge feeder canal approximately 0.4 mile downstream of the plant, but prior to the flow dispersing into the CCS (Figure 1.1-4). The southerly station (TPFM-2) is located on the southern end of the CCS (south collector) where all water passes as it transitions from southerly to northerly flow (Figure 1.1-4). The inflow station was originally located about 0.4 mile from the intake back into the plant. The purpose of the flow meters was to help assess losses and gains in CCS water volume and flows as part of the water budget.
Each of the stations was equipped with a side-looking ADFM (Argonaut-SL 500, Sontek/YSI, Yellow Springs, Ohio) that emits three acoustic beams in a characteristic pattern (i.e., two horizontal beams separated by 50 degrees and one vertical beam) (Figure 2.5-1). Each station is powered using a solar-charged lead acid battery. All data are stored in a datalogger (CR800, Campbell Scientific, Logan, Utah) and remotely transferred to a permanent database daily via telemetry. The data loggers are programmed to record indexed velocity and flow every 15 minutes.
Platforms to support these ADFMs were constructed in the summer of 2010. The meters were subsequently installed by YSI following industry standard protocol (i.e., mount the sensor plumb
+/-2 degrees, no obstructions above or in front of the sensor, etc.). Stream gauging and indexing efforts were conducted with the final installation indexing efforts completed in November 2010.
Results of the initial indexing effort were provided in the August 2011 Annual Report (FPL 2011b).
Significant turbulence at TPFM-3 yielded poor data quality, and subsequent equipment failure resulted in removal of the flow meter in December 2010. This flow meter was repaired, but has not been reinstalled at TPFM-3 primarily due to issues with data quality, limitations in alternative inflow locations, and concerns of short-circuiting in the CCS. The issue of short-circuiting has been discussed with the Agencies. This issue limits the usefulness of the flow meters as originally envisioned. FPL collected temperature data to help confirm if short-circuiting of water from the discharge canals into the Grand Canal and return canals is occurring under the berms in the CCS. The greatest potential for underflow is the berm that separates the return Grand Canal and the discharge canal immediately adjacent to the Grand Canal, since the head differential between these two canals is the greatest. Results from this effort were presented to the Agencies on March 21, 2012, and indicated that some underflow may be occurring due to higher temperatures in the Grand Canal in comparison to the adjacent return canal to the east; however, the amount of underflow could not be determined.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 The other two meters recorded data through July/August 2011, but became inoperable and were pulled for troubleshooting in the field. TPFM-1 was not operating in June 2011, and FPL replaced that flow meter with the one that had been previously pulled and repaired from TPFM-
- 3. This flow meter recorded data for approximately one week (late June/early July 2011) before malfunctioning. At TPFM-2, data were collected until the mounting bracket broke in early August 2011. All flow meters were sent to YSI for diagnostics. These two meters were subsequently repaired, the mounting brackets were repaired, and the flow meters were reinstalled on May 29, 2012. Indexing was conducted during this reinstallation effort (on May 31) and the information is presented in Appendix F.
2.5.2 Results and Discussion This report includes data that has been recorded by all flow meters since initial installation on July 27, 2010. As the Agencies have expressed interest in these data, it has been post-corrected based on the initial indexing efforts and the results are included with the entire data set for the monitoring period. Figure 2.5-2 shows the available velocity and flow meter data that were collected during the pre-Uprate period.
The results show the variations in flow over time, with the most notable changes directly associated with major plant outages at the nuclear units. Velocity in the CCS ranges from 0.33 foot per second (ft/s) to 2.4 ft/s, with generally higher values observed at TPFM-2 relative to TPFM-1 (Figure 2.5-2). Average velocity is 0.89 +/- 0.19 ft/s (average +/- standard deviation) at TPFM-1 and 1.62 +/- 0.36 ft/s at TPFM-2. The channel is narrower at TPFM-2, hence resulting in greater velocities.
Flow rates of 1,032 cubic feet per second (ft3/s) to 4,367 ft3/s were observed in the CCS during the period of record. Average flow rates were 3,810 +/- 613 ft3/s at TPFM-1 and 2,507 +/- 520 ft3/s at TPFM-2. There was a significant positive correlation between the flow at both sites (FlowTPFM-2 = 0.8113(FlowTPFM-1) + 134.27; R² = 0.8708), as shown on Figure 2.5-3. Flow was higher at TPFM-1 relative to TPFM-2 (Figures 2.5-3 and 2.5-4) for 92.6% of the time although this pattern was sometimes reversed. Lower flow at TPFM-1 when simultaneously compared to TPFM-2 may in part be caused by plant operations when pumps are turned on and off or varying rainfall distribution over the CCS which can affect flow in different reaches of the CCS.
During an outage, less water is typically needed for cooling and thus less water is pumped through the plant. While the pumpage rates vary, depending on factors such as the specific reason for the outage and length of time, there are some typical considerations for the plants operating/shutdown conditions. Each nuclear unit has four circulating water pumps (CWPs; about 156,250 gallons per minute [gpm] each) and three intake cooling water pumps (ICWPs; about 16,000 gpm each). CCS water is pumped through the nuclear units for cooling. The nuclear units typically operate at full power with four CWPs and two ICWPs during operation.
During a planned nuclear plant refueling shutdown (every 18 months), the CWPs are turned off and the shutdown unit uses one or two ICWPs for plant cooling purposes. The CWPs are returned to service when the unit is ready to restart. During the major scheduled Unit 3 Uprate 2-22
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 outage that started in March 2012, the CWPs were turned off. Figure 2.5-2 shows the drop in flow in late September 2010 through late October 2010 and again in mid-March 2011 through early May 2011 during refueling outages.
The two fossil units each have two CWPs (about 137,000 gpm each) and two open cooling water pumps (OCWPs; about 6,000 gpm each). Typically, during operation a fossil unit will use both CWPs and one or two OCWPs depending on cooling requirements. CCS water is pumped through the fossil units for cooling. Pumps in Unit 1 are periodically turned on to maintain its operational readiness as this unit is online during peak seasonal demand periods. However, Unit 2 is currently being used as a synchronous generator and is not producing megawatts (MWs; or steam heat). Unit 2 is typically using the OCWPs for cooling. The complete outage reports for this pre-Uprate period are in Appendix F.
Figures 2.5-5 and 2.5-6 illustrate representative flows over two separate weeks compared to tidal fluxes at TPBBSW-3 in Biscayne Bay. The graphs show daily patterns with a week. These flows are representative of values observed during a week of normal Turkey Point Nuclear Plant operations (January 23 through 30, 2011) and during the outage of Unit 4 (March 23 through 30, 2011). As Units 3 and 4 are the primary drivers of flow within the CCS, flows during the Unit 4 outage were approximately half of normal plant operations in March 2011 (Figure 2.5-2). When flow rates are compared against the tidal fluctuations in Biscayne Bay, there appears to be no relationship between the tidal conditions and the flow rates in the CCS.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Executive Summary EXECUTIVE
SUMMARY
Florida Power & Light Company (FPL) has prepared this Comprehensive Pre-Uprate Monitoring Report pursuant to Conditions of Certification IX and X of its Power Plant Site Certification for the FPL Turkey Point Units 3 and 4 Nuclear Power Plant and Unit 5 Combined Cycle Plant (PA 03-45A2). The Monitoring Plan was developed with input from the Florida Department of Environmental Protection (FDEP), the South Florida Water Management District (SFWMD), and Miami-Dade Countys Department of Environmental Resources Management (DERM),
(collectively, the Agencies), and FPL. The Monitoring Plan requires the collection of groundwater, surface water, meteorological, flow, and ecological data in and around the plant to establish pre-Uprate baseline conditions and determine the horizontal and vertical effects and extent, if any, of the cooling canal system (CCS) water.
FPL has prepared this Comprehensive Pre-Uprate report to document its efforts to establish a pre-Uprate baseline conditions for the required two year pre-Uprate period. The purpose of this report is to summarize and provide analysis of the data collected. This report incorporates information presented in the previous semi-annual reports (FPL 2011a, FPL 2012a) and first annual report (FPL 2011b). It includes data from June 2010 through June 2012.
In accordance with the Monitoring Plan, FPL installed an extensive monitoring network of 47 groundwater wells and 20 surface water stations, a meteorological station, rainfall gauges, and flow meters in the CCS and surrounding area. The groundwater and surface water stations measure and record specific conductance, salinity, water levels, and temperature at 15-minute intervals. Groundwater and surface water samples are collected across the vast network of stations every three months and analyzed for a broad suite of parameters. FPL conducted extensive ecological monitoring and studied flora and fauna in Biscayne Bay, marshes, and mangroves. Initially, FPL collected water samples from the shallow soils (referred to as porewater) at hundreds of locations that covered a 75 square mile area in the vicinity of the CCS and analyzed for a broad suite of parameters.
As required by the Monitoring Plan, FPL has developed a water budget. This analysis calculates components of water and salt inflow and outflow from the CCS on a daily basis. The water budget helps explain the dynamics of CCS hydraulics and may be used to assess the effect of climatic or operational changes on the CCS water levels and salinities.
The Agencies and their experts considered and analyzed the previous data collected and have selected tritium as the tracer. FPL disagrees with the low tritium threshold that the Agencies selected when evaluating potential movement of the CCS. Tritium is a by-product of the nuclear fission process and is unique to and present in and around the CCS. It is important to note that tritium is being measured only as a chemical tracer in order to determine the potential movement of CCS water. At the levels being measured, the tritium is not a public health concern. Tritium is ES-1
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Executive Summary routinely monitored in the CCS by the Florida Department of Health, Bureau of Radiation Control and there have never been results detected near the drinking water standard (20,000 picoCuries per liter).
The results of the two years of pre-Uprate data analysis are summarized below.
Biscayne Bay groundwater results support the conclusion that there is little or no influence from the CCS in the area fronting the northern half of the CCS. However, there is evidence of CCS water under Biscayne Bay in close proximity to the southern tip of the CCS. Over the two year monitoring period, the results indicate that the salt constituents and tracer have remained consistent for all wells. This is indicative of the groundwater maintaining a relatively stable condition during this time period.
Groundwater results immediately adjacent to the CCS indicate the presence of CCS water.
Further west from the CCS, there is some influence of CCS water in decreasing concentrations at depth out approximately three miles. The outermost wells approximately six miles to the west are fresh at all depths. Similar to the wells in the bay, the results indicate the salt constituents and tracer have remained consistent for all wells. This is indicative of the groundwater maintaining a relatively stable condition during this time period. A shallow fresher water lens still exists west of the CCS and is supported by the induction logging conducted for this project and the continuous specific conductance profiling done in several historical wells for the interceptor ditch (ID) monitoring. This lens is 10 to 20 feet deep from the surface and generally thickens towards the west.
In most surface water stations, there is no influence of CCS water via groundwater pathway.
There are two locations in the surface water canal stations immediately adjacent to the south end of the CCS where there appears to be some CCS water present.
FPL concludes the CCS does not have any ecological impact on the surrounding areas. FPL further concludes there is no evidence of CCS water in the surrounding ecosystems from a groundwater pathway.
FPL concluded that atmospheric deposition of the tracer can affect the surface water, porewater, and very shallow groundwater results as indicated by measured concentrations of tritium and must be considered when evaluating CCS surface water and porewater results. These tritium values are more concentrated immediately adjacent to the CCS and diminish with distance from the CCS.
It is important to understand the historical context of saltwater in the region and to the west of the CCS. Saltwater intrusion pre-dates the construction of the CCS and extended far inland in the 1940s (Klein 1957). Based on historical data, much of the groundwater in the vicinity of the CCS was non-potable. The extent of saltwater intrusion, as defined by the U.S. Geological Survey, varies from year to year but the landward extent of the saltwater intrusion today is still similar to that reported in the 1950s.
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Executive Summary FPL and the Agencies conducted a joint study separate from the Monitoring Plan to determine the landward extent of the saltwater orientation in the region prior to construction of the CCS. In August 2011, FPL and the Agencies reached agreement on the conclusions as documented in a report Saltwater Orientation in the Biscayne Aquifer in the Turkey Point Plant Vicinity Prior to Installation of the Cooling Canal System. Based on data from the Monitoring Plan, as compared to this report, the western historical extent of saltwater has not changed appreciably since the construction of the CCS in 1972. In fact, all the well clusters furthest to the west contained freshwater historically and still do today. Directly beneath and adjacent to the CCS, the saltwater wedge is closer to the land surface than it was prior to the CCS installation.
In conclusion, FPL has completed two years of pre-Uprate baseline monitoring. Many factors can cause saltwater intrusion, including groundwater withdrawals, agricultural uses, mining, government water management practices, etc. The impact of CCS water at a particular location, the relevancy of its presence, and how the water reached that location, must be considered when assessing the results and determining how to proceed.
FPL has recommended some changes to the monitoring, particularly in the interim period until 2013 when the Uprates of both Turkey Point nuclear units will be completed and those units returned to service at the Uprated power levels. Lastly, FPL makes recommendations in this report that some of the analytical parameters be eliminated.
Going forward, FPL will continue to comply with the Monitoring Plan for the required two year post-Uprate monitoring period. Since increases in temperature and salinity are expected to be minimal after the Uprate Project is implemented, there should be no presumption that the Project will cause any impact to the surrounding environment. The post-Uprate monitoring will help determine if there are any measurable impacts.
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1
- 1. INTRODUCTION Florida Power & Light Company (FPL) submits this Comprehensive Pre-Uprate Monitoring Report dated October 2012 for the Units 3 and 4 Uprate Project. This monitoring report has been prepared in accordance with the FPL Turkey Point Power Plant (Turkey Point) Groundwater, Surface Water, and Ecological Monitoring Plan, referred to herein as the Monitoring Plan (South Florida Water Management District [SFWMD] 2009a). The Monitoring Plan requires the collection of groundwater, surface water, meteorological, flow, and ecological data in and around the plant to establish pre-Uprate baseline conditions and determine the horizontal and vertical effects and extent, if any, of the cooling canal system (CCS) water. For further details, refer to the Monitoring Plan (SFWMD 2009a) and Fifth Supplemental Agreement (SFWMD 2009b).
The purpose of this Comprehensive Pre-Uprate Monitoring Report is to summarize the pre-Uprate monitoring efforts, to present and summarize the data, and to discuss results. This report incorporates information presented in the previous semi-annual reports (FPL 2011a, FPL 2012a) and annual report (FPL 2011b) and includes data from June 2010 through June 2012.
Data were collected in accordance with the FPL Quality Assurance Project Plan (QAPP) that was available at the time of sample collection (FPL 2010 and 2011c) as well as changes to the QAPP that the SFWMD, the Florida Department of Environmental Protection (FDEP), and the Miami-Dade County Department of Regulatory and Economic Resources (RER, formerly known as Department of Environmental Resource Management [DERM]) (collectively described herein as the Agencies) provided to FPL in June 2011 and the suggested revisions that FPL provided to the agencies in August 2011 and March 2012. FPLs suggested revisions more accurately reflect data collection practices being performed in the field. Any notable deviations are discussed herein and/or are found in the field and laboratory audits (SFWMD 2011, 2012a, and 2012b; FPL 2012b and 2012c).
1.1 Brief Overview of Automated Monitoring Network FPL installed an extensive automated monitoring network to collect groundwater, surface water, meteorological, and hydrologic data at 15-minute intervals over a broad area surrounding Turkey Point. Table 1.1-1 provides a summary of monitoring efforts and includes information on when the automated monitoring was initiated. A brief overview of each monitoring network is provided below, and further discussion regarding the instrumentation, data collection, and results for the network is included in Section 2 of this report. Photographs of the automated stations are included in Appendix A.
1.1.1 Groundwater From February through June 2010, FPL installed 42 wells in 14 well clusters (TPGW-1 to TPGW-14) at and around Turkey Point (Figure 1.1-1). Coordinates of each station are provided 1-1
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 in Appendix A. The locations were determined based on site conditions and extensive coordination among FPL and the Agencies. The placement of station locations in Biscayne Bay also was coordinated with Biscayne National Park (BNP).
Three separate wells were installed at each location: a shallow well (S); an intermediate depth well (M); and a deep well (D). The borehole for the deep well was drilled first, and down-hole geophysical methods were used to help determine high flow zones and other subsurface characteristics. Based on a collaborative effort among FPL, JLA Geoscience, Inc., and the SFWMD, screen depths were established with screen lengths varying from 2 to 5 feet (ft) based on site conditions. Table 1.1-2 provides a brief summary of the well construction information, and further details are provided in the JLA Geosciences, Inc. (2010) Geology and Hydrogeology Report.
Following well completion, the top of each well casing was surveyed and infrastructure (probes, telemetry, solar panels, and other elements) was installed to facilitate the collection of automated groundwater quality and stage data at 15-minute intervals. Most of the locations were re-surveyed in June 2011 to confirm the elevations. The measured water quality parameters include actual conductance and temperature. Specific conductance, salinity, density, and total dissolved solids (TDS) are calculated by the instrumentation based on the measured parameters.
Groundwater data are remotely transmitted via telemetry each day and uploaded to FPLs Electronic Data Management System (EDMS).
1.1.2 Surface Water Per the Monitoring Plan and as shown on Figure 1.1-2, automated surface water stations were installed at the following locations:
Seven stations in the CCS; Five stations in adjacent canals; Three stations in the Interceptor Ditch (ID); and Five stations in Biscayne Bay.
In addition, two non-automated stations were installed:
One station in the CCS (TPSWCCS-8); and One station in the Card Sound Road Canal (TPSWC-6).
The locations of the monitoring stations were jointly determined with the Agencies and provide broad coverage of the key water bodies in the project area. Two additional stations (TPBBSW-10 and -14) were added at a later date to record conditions in Biscayne Bay; these stations are co-located with TPGW-10 and -14. Coordinates of each station are provided in Appendix A.
The automated surface water stations record the same water quality data parameters as the groundwater stations. Stage data are recorded at all locations except four stations in Biscayne Bay that do not have the infrastructure to support stage recorders or a telemetry system 1-2
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 (TPBBSW-1, TPBBSW-2, TPBBSW-4, and TPBBSW-5). The data at these four Biscayne Bay locations are retrieved manually at approximately six-week intervals and downloaded into the FPL EDMS. Data from the other stations are transmitted via telemetry daily onto a secure server system and automatically uploaded into the FPL database.
1.1.3 Meteorological One meteorological station that includes instrumentation to measure solar radiation, wind speed, wind direction, air temperature, relative humidity, and rainfall was installed near the center of the CCS (TPM-1). Four additional rainfall gauging stations were installed around the CCS. Data are collected at 15-minute intervals. Data from the meteorological station are uploaded daily into the FPL database, while the rainfall gauges are manually downloaded during routine site visits. Seven rainfall collectors were installed around the CCS. Additionally, five evaporation pans have been installed at various locations. Figure 1.1-3 illustrates the locations of the above-mentioned stations. Coordinates of each station are provided in Appendix A.
1.1.4 Hydrological Three acoustic Doppler velocity meters (ADVMs), otherwise known as index-velocity meters or flow meters, were originally set up to determine flow in the CCS at the following three locations:
near the power plant discharge into the CCS; the southern end of the CCS before the water enters the return canal of the CCS; and near the intake into the plant from the CCS (Figure 1.1-4). All three units failed within the first two years of deployment due to the harsh conditions within the CCS; two units have subsequently been re-installed and are currently operational. Data are transmitted by telemetry and automatically uploaded to the FPL EDMS.
1.2 Quarterly Sampling for Laboratory Analysis The aforementioned monitoring network for groundwater and surface water supports the collection of water samples for laboratory analysis. The Monitoring Plan specifies samples must be collected from the 42 new groundwater wells and the 20 surface water stations previously discussed. Samples also must be collected on a quarterly basis from one additional location on the Card Sound Road Canal. In addition, a sample must be collected one time at a localized location within the CCS, identified by the Agencies as potentially having cooler water than the rest of the CCS, based on thermal imagery. The timing of the quarterly sampling efforts is shown on Table 1.1-1. The samples are analyzed for a variety of parameters including CCS Tracer Suite constituents, ions, trace elements, nutrients, and TDS, along with field parameters, depending on the locations and whether the effort was a quarterly or semi-annual event.
Further discussion of the analytical parameters, sample collection methods, and results is provided in Section 3 of this report. The analytical data include sampling events conducted in June/July 2010, September 2010, December 2010, March 2011, June 2011, September 2011, December 2011, March 2012, and June 2012.
1-3
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Samples were also collected at five existing historical wells as part of FPLs routine sampling for the ID operation. Samples were collected from historical wells L-3, L-5, G-21, G-28, and G-35 in October 2010 and January 2011. Initially, the timing of these sampling events was offset from the Monitoring Plan sampling events but, based on discussions with the Agencies following the January 2011 sampling effort, FPL changed the ID operation sampling to occur in the same month as the Monitoring Plan sampling. Results from the March 2011, June 2011, September 2011, December 2011, March 2012, and June 2012 sampling events, as well as the October 2010 and January 2011 events, are included in this report.
1.3 Ecological Monitoring The Monitoring Plan and QAPP outline an ecological monitoring program. Biotic components of interest include marsh vegetation in adjacent wetlands, mangroves, submersed aquatic vegetation, and benthic fauna in and adjacent to Biscayne Bay. Table 1.1-1 provides a summary of the ecological monitoring efforts conducted. More detailed information on the transect plot setups, sampling methods and materials, laboratory results, findings, and conclusions are included in Section 4 of this report.
1.3.1 Marsh and Mangroves Plant community characteristics (composition, cover, canopy, height, productivity), leaf characteristics, nutrient content in the leaves and soil/sediment, and porewater quality are being assessed in 12 transects in marsh and mangrove areas around the CCS (Figure 1.3-1). Two (one each in the marsh and mangrove) of those transects are in reference areas. Ecological monitoring efforts were initiated in October 2010 and completed by December 2010. Additional monitoring in the marsh and mangrove areas was conducted on a quarterly basis in February 2011, May 2011, August 2011, November 2011, February 2012, and May 2012.
1.3.2 Biscayne Bay Submerged aquatic vegetation (SAV), coral and sponge community composition and cover, fish and invertebrate species composition and abundance, nutrient content in seagrass leaves and sediment, light attenuation, and porewater quality are being assessed in 20 transects that parallel the shoreline (Figure 1.3-1). The monitoring in Biscayne Bay is conducted twice a year.
Originally, the plan was to conduct monitoring in May and October; however, during the setup of transects in October 2010, FPL noted that the seagrasses had already senesced by the time sampling was initiated. With concurrence from the Agencies, the subsequent ecological monitoring in Biscayne Bay was changed to April and September with the subsequent monitoring efforts conducted in April 2011, September 2011, and April 2012.
1.3.3 Broad-Scale Porewater Survey In accordance with the Monitoring Plan and through coordination with the Agencies, an initial broad-scale survey of porewater temperature and specific conductance was conducted in March/April 2010 (dry season) at over 200 locations in adjacent wetlands and Biscayne Bay 1-4
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 (Figure 1.3-2). A second porewater temperature and specific conductance survey was conducted in August 2010 (wet season) at 100 locations in Biscayne Bay (Figure 1.3-3). Based on the initial temperature and specific conductance measurements, locations were established for the porewater samples that would be collected for Tracer Suite laboratory analysis. The wet season Tracer Suite sampling effort took place in October 2010 and the dry season sampling event was conducted in April 2011. While details of this effort are in the report titled Turkey Point Plant Initial Ecological Characterization Report (FPL 2012d), summaries of the approach and the findings are provided herein. The results, when used in conjunction with the other data, increase understanding of baseline porewater conditions across the broader landscape.
1.4 Hydrogeologic Assessment 1.4.1 CCS Water Budget FPL has worked closely with the Agencies to develop an acceptable methodology for the CCS water budget. This methodology has evolved and is included in Section 5 of this report.
Estimated monthly water budgets and salt loads from September 2010 through June 2012 are included in Section 5.
1.4.2 Regional Assessment and Extent of CCS Water With the aid of data collected as part of the well installation efforts, automated data and analytical results, United States Geological Survey (USGS) induction logs, and other supporting documentation, FPL has conducted an initial assessment of the hydrogeologic conditions in the area surrounding Turkey Point and the CCS, which provides some insights into how the groundwater system responds to different environmental conditions and operation of the CCS.
The rate of migration and extent of CCS water in the groundwater are discussed in Section 5 of this report.
1.4.3 Biscayne Bay Continuous Resistivity Profile Survey The USGS conducted a pilot study in Biscayne Bay to assess the feasibility of using continuous resistivity profiling to determine the extent of CCS water both laterally and vertically in the subsurface. The survey in the Bay was conducted on May 25 and 26, 2011, with an additional transect surveyed in the CCS in July 2011. Following the processing and interpretation of the data, the USGS gave a PowerPoint presentation to FPL and the Agencies on August 29, 2012.
No report was generated to provide the information to the Agencies. The USGS indicated that preparation and publication of a report would take approximately one year due to their extensive quality assurance/quality control (QA/QC) process. Alternatively, FPL provides a brief summary of the USGSs effort and FPLs overall interpretation of the preliminary findings in Section 5 of this report.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 1.5 Interceptor Ditch Operation The Interceptor Ditch (ID) is located immediately west of the CCS and is designed to prevent seasonal inland movement of saltwater from the CCS into the potable portion of the Biscayne Aquifer. Shallow saline groundwater is intercepted by the ID and pumped back to the CCS during the dry season or other times when the natural gradients are low and the potential for saltwater intrusion exists. Details of the ID operation are found in the 1983 Agreement (the Agreement) between the SFWMD and FPL. On October 14, 2009, the Agreement was modified to expand the monitoring program as part of the Turkey Point Units 3 and 4 Uprate Project and added well G-35 as part of the historical monitoring network. FPL submitted a revised operations plan to the SFWMD in 2011 and comments on that plan are pending.
Since 1972, FPL has been collecting groundwater data west of the CCS and recording ID pumping as part of the ID operation. Results of these efforts have been included in reports that are submitted on a quarterly and annual basis. Based on discussions between FPL and the SFWMD, reporting of the ID operations for the last year (June 2011 through May 2012) is integrated into Section 6 this report.
1.6 Data Quality Objectives and Acceptance Criteria Data quality objectives (DQOs), along with acceptance criteria, are identified in the project QAPP. The DQOs include the following:
Precision Accuracy Analytical Sensitivity Completeness Representativeness Comparability Availability Reliability Maintainability Timeliness Quality guidelines have been established for some of the DQO which reflect quantifiable goals.
A summary of performance in meeting the DQOs is described below.
Precision Precision is a measure of mutual agreement between duplicate or co-located measurements of the same analyte. The closer the numerical values of the measurements are to each other, the more precise the measurement.
1-6
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Precision for laboratory samples is established by the evaluation of field and laboratory duplicate samples. If the relative percent difference (RPD) between the sample and the duplicate result differ by more than 20%, the results for that analyte in both samples are qualified as questionable. While a small percentage of sample data has been qualified due to high duplicate RPDs, overall, the analytical results are comparable to duplicate samples for those samples using the same method. These precision results indicate the sampling and analytical procedures are consistently performed and repeatable. Details are provided in the Data Usability Summary (DUS) Reports issued for each event.
To assess precision of the probes being used to collect time series water quality and water level data, field measurements are taken during cleaning and calibration events to verify the results.
This is discussed further in Section 2 of this report. If the specific conductance value reported by the field verification measurement is more than 30% higher or lower than the automated probe reading, the automated probe data are qualified as questionable (?) back to the previous cleaning and calibration event or, at minimum, back to an interim point where there is an unexplained shift in the data. While most of the data do not need to be qualified, the numerical degree of variability is greater in the high saline locations.
Similarly, if a temperature verification measurement is more than 0.5 degrees Celsius (°C) different than the automated probe reading, the data are qualified in the same manner. Rarely has the water quality data been qualified for not meeting a field instrument verification reading.
For verification of water level precision, refinements were made during the monitoring program.
These refinements included the collection of water level measurements with a water level indicator at different times during the cleaning and calibration event. These refinements allowed the determination of the water level before pulling the probes for cleaning and after placement of the probes to verify correct reference level settings. If the difference between the verification water level reading (before the probe is pulled for cleaning) is greater than 0.1 ft from the automated probe reading, the data are qualified as estimated (J) back to the previous cleaning and calibration event or, at minimum, back to an interim point where there is an unexplained shift in the data. The precision has improved over time; however, the biggest challenge has been associated with the surface water stations in Biscayne Bay and the CCS. Sometimes wave action at these larger surface water body locations affects the water level indicator readings, making verification of the automated reading more difficult. Only a limited amount of water level data is qualified as questionable due to verification readings.
Accuracy Accuracy is the measure of bias in a measurement system. The closer the value of a measurement agrees with the true value, the more accurate the measurement.
For the analytical results, accuracy is evaluated using percent recoveries of analytes added, termed spiked, to samples (matrix spikes [MSs]) or reagents (laboratory control samples
[LCSs]) and carried through the extraction and analysis procedure. Laboratory-established acceptance criteria (within method requirements) are used for LCS and MS percent recoveries.
1-7
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 LCS percent recoveries have consistently passed acceptance criteria for all analyses indicating the laboratories extraction and analysis procedures and materials met method requirements.
In contrast, some MS recoveries have been qualified as estimated (J) or unusable (?) due to poor recoveries. Results with MS recoveries outside laboratory-established limits are qualified as J and recoveries less than 10% are qualified as ? as the low recovery indicates a significant possibility of error associated with the sample result due to the matrix effects. Results were qualified as ? in two total phosphorus, one chloride, one sulfate, and one fluoride result in saline water samples. Results were qualified as J in many of the samples analyzed for matrix spikes, especially with regards to nutrients. This trend will be followed during future events as it could indicate a possible error associated with the accuracy of the results due to matrix interferences.
In addition to recoveries, accuracy is evaluated using technical comparison checks, including cation and anion charge balance; cations, anions, and TDS compared to the specific conductance; total ammonia less than total Kjeldahl nitrogen (TKN); and orthophosphate (OP) less than total phosphorus (TP). Many cation and anion results, particularly in the high salinity samples, have been qualified as either J or ? due to ion charge and conductance comparisons. TDS/specific conductance and ammonia/TKN comparisons were acceptable.
TP and OP were first sampled in events from June 2010 to February 2011 and the OP had higher results than the TP. In March 2011, the OP analytical method was modified based on a FDEP Laboratory SOP (NU-070-1.8). The sample is analyzed without the color reagent to establish a background concentration. The sample is then analyzed per the method and the background concentration is subtracted from the analytical result. Since the method modification, the OP/TP comparisons have been within the criteria.
The laboratory is considering switching to saline reagent waters to better simulate the sample matrix and reduce matrix-induced interference effects. In addition, certified reference materials (CRMs) for nutrients in saline waters are being analyzed to evaluate the validity of the laboratory results for these methods.
To further evaluate laboratory accuracy, field split samples were collected by RER in the March 2012 semi-annual sampling event and analyzed by the RER laboratory. Samples were collected from select deep wells into separate containers, shipped to TestAmerica Laboratories, Inc.
(TestAmerica) and the RER laboratory, and analyzed for ammonia, nitrate/nitrite, TKN, TP, and OP. While the number of data pairs compared (four) is too small to draw major conclusions, there are some significant differences (RPD>50%) among the results for ammonia, TKN, and OP. The two laboratories follow essentially the same methods; however, even minor differences in procedures or materials can affect the analytical results. At this point, it is unclear which set of results is more accurate of the actual groundwater conditions at the time of sampling. It should be noted that the RER results have ammonia consistently greater than TKN, which is not possible; TKN is the sum of ammonia, ammonium, and organic nitrogen. FPL/TestAmerica is reviewing the RER SOPs and is performing analysis of CRMs to aid in the evaluation of the overall sample results.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 The instrumentation for all the automated station instruments and field equipment meets the requirements for accuracy per the QAPP. All stations were surveyed with vertical control established to second order closure (accuracy within hundredths of a foot) with the exception of three groundwater cluster stations in Biscayne Bay. The top of the groundwater wells and surface water stilling wells at these Biscayne Bay stations were surveyed with GPS instruments to an accuracy of 0.1 ft.
Analytical Sensitivity For data validation, qualification and reporting purposes, analytical sensitivity is expressed by method detection limits (MDLs). MDLs are set such that the minimum concentration of an analyte is reported within 99% confidence that the analyte is greater than zero.
Project-required MDLs are listed in Table 3.2-1 of the QAPP. The MDLs are based on applicable criteria, MDLs listed in the Automated Data Processing Tool (ADaPT), Florida Administrative Code (F.A.C.) 62-4.246(3), and stated laboratory capabilities. While the majority of analytical detection limits have met the QAPP requirements, a few have been difficult to achieve due to the saline nature of the samples. This is particularly an issue with the trace metals and fluoride. The laboratory has had to dilute the saline samples to keep instruments from being overloaded with the major ion constituents (i.e., chloride, sodium). This has resulted in some data reported as Not Detected (U) but with detection limits above the QAPP requirements. In addition, these dilutions increase the uncertainty, or error, associated with a result. The laboratory is working to expand or tailor calibration ranges, within method requirements, to fit project samples and reduce the frequency of dilutions needed.
To achieve the required MDLs, the laboratory will be adding preparatory EPA Method 1638 (Determination of Trace Elements in Ambient Waters by Inductively Coupled Plasma Mass Spectrometry) for manganese and molybdenum and EPA Method 1640 (Determination of Trace Metals by Pre-concentration and ICP-MS) for the other trace metals listed above starting in September 2012. The added step will selectively concentrate certain metals prior to analysis to improve detection limits. For fluoride, the laboratory has modified the instrument performing the anion analysis (Method 6010) to allow for lower required dilutions and achieve the QAPP-required MDL. In addition, a fluoride selective probe method is being reviewed as a possible analytical alternative for fluoride only.
Completeness Completeness is expressed as the percentage of valid or usable measurement to planned measurements. The higher the percentage, the more complete the measurement process. The number of planned measurements is based on when the infrastructure is in place and functional.
Per the QAPP, the completeness goal for water quality measurements is 95% and 90% for all other data.
All planned groundwater, surface water, and porewater measurements have been made with a few exceptions. The well clusters at TPGW-10, TPGW-11, and TPGW-14 were not sampled 1-9
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 during the June 2010 event as they had not been completed at that time. Some data have been qualified as unusable and, in a few instances, the sample was lost by the lab prior to analysis.
For the nine groundwater and surface water events (four quarterly and five semi-annual) since the start of the project, approximately 31,000 groundwater and surface water analytical data points were scheduled to be reported. Of those, fifteen results were qualified as unusable and thirty results (all isotopes) were not reported due to laboratory errors. For the seven porewater sampling efforts conducted at the ecological transects since the start of the project through May 2012, a total of approximately 10,600 porewater analytical data points were scheduled to be reported. Of those, four (all OP) were reported as unusable and twelve results (isotopes and ions) were not reported due to loss of the sample by the laboratory. This results in a completion rate of greater than 99% in meeting the project objectives. It should be noted that some isotope results have not been received at the time of this assessment and as such, the totals reported above are based on available data.
All the planned ecological measurements have been made with the exception of eliminating the collection of some data in the tree islands due to health concerns about excessive poison ivy on the islands. Any changes in sampling have been agreed to by the Agencies.
The automated water quality data are calculated to be 89% complete. This percentage is lowered as a result of specific conductance oscillations related to probe or cable malfunctions or radio frequency wave interferences, most notably in well clusters TPGW-1 and TPGW-13. FPL and the probe manufacturer have conducted numerous efforts to fix the problem; oscillations still occur, but less frequently.
Meteorological data at TPM-1 are 99% complete. Rainfall data at other stations and CCS flow meter data are less complete. Some of the other rain gauges have had various problems including wiring issues, malfunctioning equipment, or excessive battery drain which have resulted in data gaps. Most of the rain gauge problems have been resolved but since they are not on telemetry, the potential for data gaps of one to two months can still exist if a gauge fails.
Gaps in the rain data can be addressed by interpolating results from other stations or using Next Generation Weather Radar (NEXTRAD) data from the SFWMD. Data from the CCS flow meters are less than 50% complete due in part to a number of equipment related issues. These meters are located in a harsh environment and have been removed for various reasons due to hardware components rusting and breaking or instrument failure. The flow meters were going to be used by FPL as a check to the water budget, however, based on findings discussed by FPL in Section 5, it is doubtful if the flow meter data will be used as originally envisioned.
Representativeness Representativeness is a qualitative parameter that expresses the degree to which data accurately and precisely represent the environmental condition. The sampling locations and techniques as outlined in the Monitoring Plan and QAPP provide data that are representative of conditions in the CCS and the surrounding environment.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Groundwater wells are placed in discrete high flow zones and are spatially distributed to reflect changes in groundwater levels and quality across the landscape. Automated data are collected at 15-minute intervals, an adequate duration to reflect temporal changes in water levels, water quality, water flow, and various meteorological parameters.
Comparability Comparability is a qualitative parameter expressing the confidence with which one set of data can be compared to another. Nearly all the data, unless qualified as ? or unusable for other reasons, are comparable. Methods of data collection and analysis have remained primarily consistent over the two years of sampling. Some refinements in data collection have helped improve efficiency or verify precision, but have not necessarily improved precision.
The most notable data that may not be directly comparable are some of the nutrient results. As noted in the Accuracy section above, the method of analysis for OP was modified beginning with the collection of data in the March 2011 sampling event; OP data collected prior to March 2011 using the original method are not directly comparable to data collected during and after the March 2011 event. The data prior to the March 2011 event are believed to be biased high due to background fluorescence levels interfering with the analysis.
Nitrate/nitrite samples collected in March 2012 were filtered in the field, as will be done in subsequent events. Previously, the samples were distilled in the lab and not filtered in the field.
It is expected that the results are similar. Rarely does one find insoluble forms unless they are large particulates which would not be analyzed in any case; they would have to be removed as they would interfere with the analysis. This was further demonstrated by the March 2012 PERA split samples. The samples were analyzed as filtered and unfiltered for ammonia and nitrate/nitrite with essentially identical results. Therefore, the ammonia and nitrate/nitrite results from both method variations are considered comparable.
Availability Availability is the percentage of time that a system or function is available for service according to established criteria and the probability that the system is operating satisfactorily at any point in time, excluding times when the system is under repair. This DQO applies primarily to the automated systems.
While FPL has not calculated percentages, the stations that report automated water level and water quality collectively have a high degree of availability. These systems operate round the clock, the probes have been reliable, and spare probes and cables are on-hand to fix a problem station. The meteorological station has been reliable with no down time, thus has a high degree of available data for solar radiation, wind speed and direction, air temperature, relative humidity, and rainfall. The other rain gauges and CCS flow meters appear to record good data when operational, but some of the instruments have failed for extended periods of time. Since the individual rain gauges are not on telemetry, whether the system is operating satisfactorily or not is unknown until the site is visited monthly or bi-monthly and data are downloaded and reviewed. The CCS flow meters are more difficult to maintain.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Reliability Reliability is the probability of a system performing a specified function without failure for a specified period of time. A failure occurs when a measurement or control action does not comply with established accuracy, completeness, or timeliness standards. This DQO applies primarily to the automated systems.
Collectively, the stations that report automated water level and water quality are reliable in the context of data usability. The associated probes that measure and record the data meet the accuracy requirements and exhibit high percent completeness. As previously indicated, some stations have reoccurring issues with oscillating specific conductance data and the precision at some of the higher saline sites is reduced; however, only a small percentage of the data are qualified ?. Reporting of the automated data from the stations on telemetry has typically been on a daily basis. However, a number of transmission/signal issues have occurred when the data have not been consistently reported within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for all stations. Still, in most instances, the data are stored internally on the probe and eventually downloaded when a phone connection is made or the data are manually downloaded into the system. The quality guideline for reliability, as stated in the QAPP, is difficult to judge since it reflects a mean time between failures of 18 to 24 months depending on the system. While there have been failures in less than 18 months, the majority of the data are usable and no decisions are being made on the raw data that is being transmitted via telemetry.
The meteorological station at TPM-1 has not failed and reports regularly, thus it maintains a high level of reliability. The rain gauges at the other sites have less complete data and thus have a lower reliability.
Maintainability Maintainability is the ease with which a component or equipment can be modified to correct faults. The quality guideline per the QAPP for completion of repairs to components or equipment is 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Given the size of the system, remote locations of some stations, and the occasional need for extended troubleshooting efforts, strict compliance with the guideline is not always possible or even appropriate. The automated groundwater and surface water stations (inshore) are easier to maintain than some of the other systems, however, some of the oscillation and daily reporting issues have required extensive troubleshooting. On at least a weekly basis, FPL checks for any automated groundwater and surface water stations that are on telemetry but are not reporting. Often the lack of reporting is related to low signal strength or loss of telephone connection the previous day and not to an equipment malfunction. Usually, the system will eventually report. Also on a regular basis, FPL looks at time series plots of the data to see if there are any unusual data trends or oscillations requiring troubleshooting and repair efforts.
The CCS flow meters are more difficult to maintain since they are the most sophisticated pieces of equipment and are affected by the harshest conditions. Rarely can the meters or the associated infrastructure be repaired in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. FPL suggests modifying the maintainability goal in the QAPP to take logistical constraints and other realities more into account.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 1 Timeliness Timeliness is the promptness of reporting a measurement after it is made, reporting deficiencies, submission of reports or other project documentation, addressing corrective actions, and reporting deviations within the timeframes specified in the QAPP or within the Monitoring Plan or Agreement.
Per the QAPP, the analytical data have been consistently provided to the Agencies within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> following FPLs receipt of the data from the laboratory. While much of the data from the primary laboratory is in ADaPT format, such data has not undergone a full QA/QC review at the time it is submitted to the laboratory. Since the samples are analyzed by various laboratories, the results are received at different times with several of the isotope results (notably strontium and tritium) taking the longest to obtain. Once all sample results are obtained for a sampling event, a full QA/QC check of the data is conducted and FPL generates DUS Reports. The data are also further assessed during the preparation of semi-annual and annual reports; occasionally, suspect results are found and subsequently qualified.
The automated systems are currently set to report values at 15-minute intervals and, for those systems on telemetry, to upload the results daily. As previously discussed, low signal strength or other issues have prevented various telemetry units to consistently report every day. While the raw data can be viewed by the Agencies in FPLs electronic database, the data are not official until FPL has conducted a full QA/QC review.
If additional errors are noted in the data following the QA/QC process, the results are updated in the database or DUS, as applicable, and are included in an errata or the subsequent annual report.
Reports have been submitted to the Agencies per the timeframes outlined in the QAPP or in accordance with revised schedules agreed to by the Agencies.
Once there is concurrence that corrective actions from field and laboratory audits are needed, corrective action is typically implemented immediately or by the next sampling event.

- 2. AUTOMATED DATA COLLECTION 2.1 Groundwater Quality 2.1.1 Instrumentation and Data Collection Methods Automated groundwater monitoring stations were installed at 14 well clusters in a total of 42 wells (three wells per cluster) from February 2010 to August 2010. In each well, two probes manufactured by In-Situ, Inc. (an Aqua TROLL 100 [AT100] and a Level TROLL 500
[LT500]) were deployed primarily between June 2010 and September 2010 and were set to record water quality parameters and water levels, respectively, at 15-minute intervals. The probes were connected by cable to a telemetry unit and the data at each of these sites are transmitted remotely by cellular phone service to a central database once per day. The telemetry units are powered with 12-volt batteries that are recharged by solar panels. Figure 2.1-1 shows an automated groundwater station with telemetry.
The focus of this subsection is on the AT100 probe that measures groundwater quality parameters. The AT100 has a titanium body with a completely sealed, internal lithium battery, a real-time clock, a datalogger, and temperature and conductance sensors. At each well, an AT100 is placed in the middle of the screened well interval and measures actual conductance (microSiemens per centimeter [S/cm]) and temperature (degrees Celsius [°C]). This probe also calculates specific conductance, salinity, TDS, and water density. Salinity values are calculated using actual conductance and temperature and are reported in practical salinity units (per Practical Salinity Scale 1978 [PSS-78]). TDS is based on actual conductance with a manufacturer automated default conversion factor of 0.65, and results are reported in milligrams/liter (mg/L). Water density is calculated using salinity and temperature, and results are reported in grams per cubic centimeter (g/cm3).
Per the QAPP, the ideal cleaning and calibration schedule for the groundwater probes is approximately every eight weeks, with the Biscayne Bay probes on a rotation of approximately every six weeks. The actual schedule varies depending on field conditions and logistics.
For the cleaning and calibration efforts, probes are pulled from each well and the accuracy of the specific conductance and temperature readings are verified. For specific conductance, each AT100 is placed in a container with a known conductance solution near the expected sample value and Continuing Calibration Verification (CCV) performed. The reading on the probe and the value of the specific conductance solution is recorded. A value within 5% of the standard solution is considered acceptable; if the probes reading falls outside the 5% range, data from the previous calibration event up to the present reading are qualified as estimated (E) or questionable
(?) as discussed later in this section. Following the CCV, the probes are cleaned with analyte-2-1
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 free water and a non-abrasive cloth or sponge. Sensor heads are cleaned using cotton swabs or soft pipe cleaners.
Following the CCV, an initial calibration (IC) and an initial calibration verification (ICV) are conducted with a solution at the high end of the expected sample range. The AT100 and Aqua Troll 200 (AT200) use a single-point calibration equation. If the specific conductance reading of the probe during the IC and the value of the calibration solution is between 0.98 to 1.02 of each other (referred to as the cell constant), the reading is considered ideal, but a higher range between 0.90 and 1.10 is acceptable. Following cleaning and a successful IC, an ICV and two additional bracketing ICVs are done with standard conductance solutions, with one typically above and another typically below the expected sample value range, to bracket the range of readings. If a probe specific conductivity reading is outside of the acceptable range during any of the steps described above, the probe is replaced.
For temperature, each AT100 is verified during each cleaning and calibration event using a National Institute of Standards and Technology (NIST)-certified thermometer. The temperature reading of the probe is considered acceptable if it is within +/-0.5°C of the NIST thermometer reading. If a probe temperature reading is outside the acceptable range, it is replaced with another probe.
During cleaning and calibration, operational parameters involving general system functionality are addressed. The external battery voltage that powers the telemetry system (12:00 a.m. to 1:00 a.m. and 12:00 p.m. to 1:00 p.m. each day) is checked. The 12-volt batteries and solar panels are inspected, as well as fuses and wiring connections. In addition, internal voltage and memory availability of all probes are checked. Desiccants in the system are replaced during every cleaning and calibration event, and overall cleanliness is maintained. Inoperable equipment is repaired or replaced. In the event that equipment is vandalized, it is replaced.
In addition to routine cleaning/calibration, all probes are sent for factory calibration/maintenance checks approximately once every 18 months. This effort was conducted systematically from November 2011 through March 2012. If the cleaning and calibration event occurs when a probe needs to be sent for factory maintenance, the probe undergoes a CCV and high and low ICVs first to determine if it reads within the acceptable 5% range. When a probe is sent back to the factory for recalibration, another probe that has been factory-calibrated within the past 18 months is installed in its place. Since a replacement probe would not have recorded data prior to the current calibration, it would undergo only the IC, ICV, and high and low ICVs.
From June 2010 through June 2012, the most problematic issue with the automated stations continued to be the inconsistent daily reporting by the telemetry units. In nearly all cases, the data were recorded and stored in the instrument but, due to intermittent connectivity to the network, the data were not always transmitted to the FPL database on a daily basis. In a few cases, data were lost due to lightning strikes or probe electronic resets. If the system does not reconnect after these connectivity failures, FPL has to download and manually patch in the data.
Data are downloaded from probes every calibration event, typically during cleaning and 2-2
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 calibration events. High-gain antennas are now installed at most sites. Also, several issues are causing oscillations in some of the specific conductance values. These issues are discussed in the following subsections.
2.1.2 Results and Discussion All raw data are made available to the Agencies upon receipt by FPL and are subsequently reviewed for accuracy. Depending upon the results, some of the data are qualified using the qualification codes outlined in the QAPP. The validation and qualification of the data are a substantial undertaking and will continue to be so in the future. For example, each groundwater well (one AT100 and one LT500) generates 576 data points each day. This results in 24,192 data points generated by the groundwater stations (42 wells) each day or approximately 8,830,080 points annually. Both the surface and groundwater stations generate approximately 16.5 million data points per year.
Data validation and qualification is a multi-step process. The first step begins with the plotting of key water quality parameters (salinity, specific conductance, and temperature) over a set validation period as well as the entire period of record. This allows a quick review of the results and identification/flagging of data that are outside expected ranges. Any evident aberrations in the resulting time series plots are then reviewed further based on specific station location, meteorological conditions, and previous results.
As a second step, the data are then compared to validation and calibration logs to ensure that the probes are recording data within the tolerances (5% for specific conductance and 0.5°C for temperature). Data within the accepted levels are deemed valid and data outside that range are qualified. For specific conductance ICVs, most probes have been verified successfully; however, some of the data have been qualified primarily due to CCVs outside acceptable levels.
Nine probes have been out of range for temperature and 25 probes have been out of range for specific conductance, resulting in the qualification of data back to the time the probes last passed verification for that parameter. Most of the out-of-range data was qualified as estimated. The calibration and verification logs for the automated station probes are included in Appendix B.
In the final step, each data point for specific conductance, salinity, and temperature is compared to its previous 15-minute value to check for any unusual oscillations that may not have been caught during the calibration and verification events. Salinity differences greater than or equal to
() 1 practical salinity unit (per PSS-78) and temperature changes 1°C that occur within 15-minute intervals are flagged, and both data rows are highlighted. Data are then manually reviewed for validity. Flagged data are compared against meteorological data and other station data to help determine if they are real or spurious observations beyond normal parameters. There have been instances when a probe has exhibited extreme 15-minute oscillations (e.g.,
fluctuations up to 80,000 S/cm) for a period of time before resuming function within normal ranges. Other examples of spurious data include occurrences of specific conductance values dropping drastically and instantaneously and remaining at low levels for days to weeks, or oscillating for one or two time intervals before instantaneously returning to original levels.
2-3
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 Once the above steps are completed and all flagged data are reviewed, the data are qualified as appropriate. The qualifiers used in the data qualification effort are E indicating an estimated value, ? indicating suspect or questionable data, G indicating a recalculated value, and C indicating a calibration event. Data dependent upon other parameters, (i.e., specific conductance, salinity, density, and TDS) are also qualified for the corresponding period when these parameters are interrelated.
The E (estimated) qualifier has been added to data that oscillate, but not more than 5% from what is believed to be the actual value, due to a system electrical/radio frequency issue. Data from the previous cleaning and calibration event up to present are also qualified as E when an CCV ranges from 5% to 30%, or when verification or bracketing is not performed. For example, when In-Situ, Inc. deployed probes without performing verification (other than what was done at the factory), these data were qualified with an E.
The ? qualifier has been applied to data that should not be included in any analyses because they may not be an accurate depiction of actual field conditions. These include, but are not limited to, the following:
Data from any probe with an CCV greater than 30%; however, no data have yet to be qualified as questionable for this reason; Specific conductance values that erroneously oscillate between high and low readings at 15-minute intervals due to problems with the automated system; or Specific conductance, temperature, and water levels artificially altered when the probe is pulled for cleaning and calibration.
During cleaning and calibration events, both ? and C qualifiers are applied to all applicable parameters. The calibration event begins when a probe starts to be retrieved and ends when it has been set back in place and the temperature reading has stabilized. When air and water temperatures differ greatly, it can take the probe temperature several hours to return to accurate readings of ambient water temperature and, thus, all values are affected.
After a review of the key parameters in their entirety by a second QA/QC person, all qualified data from each station are validated on the EDMS and, subsequently, become available for download by the Agencies.
FPL has made refinements in the data qualification and validation process during the monitoring period and, when necessary, has retroactively applied qualifiers to previous sets of data. For example, in the last Semi-Annual Monitoring Report (FPL 2012a), FPL noted that, during a few short periods, the surface water levels exceeded the top of several groundwater well casings. The groundwater levels were qualified. Also, the water quality readings in several of the wells appeared to be slightly affected during sampling events and the data were qualified. FPL went back through all the previous data to determine whether similar events occurred and qualified the 2-4
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 data as appropriate. These changes only affect a small percentage of the data. The information presented in this report reflects the most current data set.
Only a small percentage of the water quality data has been qualified as questionable. The principal reason for using the ? qualifier is erroneous oscillating specific conductance values (greater than 5% over a 15-minute interval due to obvious system malfunction). An In-Situ, Inc.
representative initially stated that these abnormal fluctuations could have been caused by air bubbles on the sensor or by blocked sensor heads. However, gently shaking and tapping the probes have not necessarily alleviated this issue in every instance. FPL subsequently re-grounded some of the sites in hopes of rectifying the problem; however, oscillations were not completely eliminated. In-Situ, Inc. was able to reproduce the oscillation in the laboratory using high-frequency radio waves. These radio waves in the laboratory caused the probe cables to resonate, which caused fluctuating specific conductance readings. In-Situ, Inc. subsequently installed ferrite beads on the probe cables to eliminate cable resonance, but data oscillations still occurred, on occasion. While the oscillations appear to be less frequent than at the projects onset, it is still believed that other factors are contributing to the oscillations; therefore, testing has continued in order to determine the underlying causes of these patterns. One of the latest tests, implemented in January 2012, disconnected external power from several of the probes showing the most frequent oscillations. To date, these probes have been disconnected from the 12-volt battery (but remain connected to the telemetry system) and have been powered by the internal 1.5-volt lithium battery and, for a while, the data appeared stable. FPL has recently run new ground wires at TPGW-1 and TPGW-13, placed ferrite beads on the cables at those sites, and connected an additional grounding rod to TPGW-1, but oscillations in specific conductance still occurs. It appears this may be an ongoing issue; the associated data will continue to be qualified as questionable.
Figures 2.1-2 through 2.1-15 illustrate time series graphs of specific conductance, temperature, and salinity at each well. These graphs depict validated data and exclude suspect data that have been qualified as questionable or that were recorded during a calibration event. Appendix D provides time series graphs of these three parameters, with all reported data including questionable data. The time series graphs show data from the beginning of station reporting in 2010 (June through September 2010 depending on station) through June 2012. To facilitate closer review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data in separate Excel files with the report.
Tables 2.1-1, 2.1-2, and 2.1-3 show statistical summaries for time series specific conductance, temperature, and salinity data, respectively. The tables include monthly average values for each monitoring well and the minimum, maximum, average and standard deviation for the entire monitoring period; these summaries were calculated where at least 21 days of data were available for that month. The salinity values are presented since lay people often relate more directly to salinity than specific conductance. Figures 2.1-16, 2.1-17, and 2.1-18 show the average value and standard deviation for specific conductance, temperature, and salinity, 2-5
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 respectively, to facilitate a spatial visualization of the average automated groundwater results.
Statistical files have been included in separate Excel files with the report.
Overall, the qualified groundwater specific conductance and salinity data indicated consistent readings throughout the entire monitoring period. The salinity results track the specific conductance results since salinity is calculated based on specific conductance and temperature.
No observable seasonal changes occurred in any well location. Nearly all the specific conductance time series plots exhibit very little change over time. TPGW-1S was the notable exception where the specific conductance values ranged from approximately 48,000 µS/cm to 64,000 µS/cm.
Similar to what has been previously observed, the wells closest to the CCS and Biscayne Bay had higher specific conductance than the wells located farther away. Outer well clusters TPGW-7, TPGW-8 (excluding TPGW-8S), and TPGW-9 have groundwater that can be characterized as freshwater and do not appear to be affected by salt water intrusion. As discussed further in Section 3, TPGW-8S had specific conductance values that ranged from 2,067 µS/cm to 3,681
µS/cm, but ionic data indicated non-marine influences. Wells TPGW-4S, TPGW-5S, and TPGW-6S had average specific conductance values over the monitoring period of 2,163 µS/cm, 1,298 µS/cm and 1,127 µS/cm, respectively. All other wells are saltier and are influenced by marine water. Monitoring wells TPGW-1M, TPGW-1D, TPGW-2S, TPGW-2M, TPGW-2D, TPGW-3S, TPGW-3M, TPGW-3D, TPGW-12M, TPGW-12D, TPGW-13S, TPGW-13M, and TPGW-13D have the saltiest water, with specific conductance values consistently in excess of 60,000 µS/cm. The specific conductance values in well cluster TPGW-13 were the highest with average values in excess of 80,000 µS/cm.
The majority of the wells that appear to be influenced by marine water had higher specific conductance values with depth; however, the intermediate zone often exhibits values similar to the deep zone. Well cluster TPGW-13 is one of the exceptions where the average values over the monitoring period were slightly higher in the shallow zone, but the values between all zones were within 5% of each other. This is not unexpected at TPGW-13 given the hypersaline conditions in the CCS.
The groundwater temperatures in the intermediate and deep zones exhibited little to no change over the monitoring period and most appear flat-lined on the time series plots. The temperatures in the shallow zone wells were steady, but reflected minor seasonal influences; groundwater temperatures were typically higher near the end/beginning of the year and decreased to their lowest levels when air temperatures were warmer, which is the opposite of what would be expected if there was an immediate response in groundwater temperature to air temperature.
This trend may be reflective of a lag in the response of the shallow groundwater (20 to 40 ft below ground surface) to winter and summer air and surface water temperatures. The highest groundwater temperatures occurred in well cluster TPGW-13 with an average value over the monitoring period of 30.0°C. By comparison, the average groundwater temperatures over the monitoring period in TPGW-10S (Biscayne Bay well), TPGW-1S (near CCS), and TPGW-9S (westernmost well) were 26.1, 25.6, and 24.7°C, respectively. The average groundwater 2-6
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 temperatures in nearly all the wells were less than the average value of 26.1°C measured at both TPGW10S and TPGW-11S in Biscayne Bay. Wells TPGW-14M and TPGW-14D had slightly higher groundwater temperatures of 26.2 and 26.4°C. Well cluster TPGW-2 had average groundwater temperatures that ranged from 26.5 to 27.4°C, which could suggest some effects of the CCS. Well cluster TPGW-2 did not follow the same general groundwater temperature trends exhibited by the other well clusters, indicating some external influence.
To assess differences between wells over time, Figures 2.1-19 through 2.1-25 show comparisons of specific conductance and temperature in shallow and deep interval wells. Figure 2.1-19 shows that for the wells in Biscayne Bay, TPGW-14 has the highest specific conductance values and the highest temperatures at depth. Figures 2.1-20 through 2.1-23 show changes across the landscape and include wells in Biscayne Bay, the CCS, and wells farther inland. The figures illustrate how much higher the specific conductance and temperature are in CCS well cluster TPGW-13 than the other wells. Also, the figures show how the values generally decrease in wells with distance from the coast. Figure 2.1-24 shows plots of wells in close proximity to the CCS. Figure 2.1-25 compares Biscayne Bay surface water specific conductance values and temperatures with Biscayne Bay groundwater specific conductance values and temperatures. The plots show how much less the groundwater specific conductance values and temperatures fluctuate than the surface water values. This indicates the buffering effects that groundwater has on surface water changes.
2.2 SURFACE WATER QUALITY 2.2.1 Instrumentation and Data Collection Methods Automated surface water quality stations were located throughout the Turkey Point landscape as determined jointly with the Agencies. All stations record water quality and stage data at 15-minute intervals, with the exception of Biscayne Bay stations TPBBSW-1, TPBBSW-2, TPBBSW-4, and TPBBSW-5 which record only water quality parameters. While most sites that record surface water data have two probes (top and bottom), some have only one probe, depending on surface water depth and other logistical considerations. Stations that are in less than 3 ft of water have only one AT200 probe. Surface water quality stations with two probes have an AT100 at approximately 1 ft above the bottom and an AT200 within 3 ft of the surface.
The AT200 is similar to the AT100, except the AT200 also measures water stage. Similar to the AT100, the AT200 has a titanium body with a completely sealed internal lithium battery, real-time clock, data logger, and pressure, temperature, and conductance sensors. The AT200 is also programmed to auto-correct water levels for water density based on readings recorded by the probe. This feature is explained in greater detail in Section 2.3.1.
Similar to the groundwater sites, probe cables are attached to a telemetry system that uploads once a day for most sites (Figure 2.2-1). Table 2.2-1 summarizes the probes used at each surface water station and the parameters measured. Currently, 33 probes (AT100s and AT200s) are deployed throughout the monitoring area, generating up to 6.3 million data points each year.
2-7
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 Four of the automated surface water quality sites in Biscayne Bay (TPBBSW-1, TPBBSW-2, TPBBSW-4, and TPBBSW-5) are not connected to a telemetry system for logistical reasons. Per the Monitoring Plan, these probes are set up similar to the BNP salinity monitoring network stations (Biscayne National Park 2007) equipped with probes that record specific conductance just above the sediment surface. Rather than installing platforms or pilings, the probes are firmly attached to a cement paver/pad and are placed at pre-determined locations on the Bay bottom.
Since these probes are designated to measure only water quality parameters, AT100s are deployed at each of these four locations. The probes are swapped out approximately every six weeks, returned to the field office where they are cleaned and calibrated, and the data are manually uploaded into the online database.
All AT100 and AT200 probes are cleaned and calibrated using the same methodology as described for groundwater sites. Appendix B shows the water quality field verification/
calibration logs. Additional verification measurements are conducted for the water level measurements associated with the AT200, as detailed in Section 2.3.1.
2.2.2 Results and Discussion The automated surface water quality data are qualified and validated in the same manner as the automated groundwater data. Figures 2.2-2 to 2.2-23 show time series graphs of specific conductance, temperature, and salinity at each surface water station. These graphs depict validated data and exclude suspect data that have been qualified as questionable (?), estimated (E), or qualified due to impacts during a calibration (C) event. Appendix C shows what data were qualified, while Appendix D shows time series graphs of the three parameters, but with all reported data including suspect data. The time series graphs show data from the beginning of station reporting in 2010 (August or September 2010, depending on station) through June 2012.
Note that the salinity results for all the surface water stations track the specific conductance results since salinity is calculated based on specific conductance and temperature, thus most of the discussion focuses on specific conductance and temperature. To facilitate closer review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data files in separate Excel files with the report.
Tables 2.2-1, 2.2-2, and 2.2-3 show statistical summaries of the time series data for specific conductance, temperature, and salinity, respectively. The tables include monthly average values for each monitoring station and the minimum, maximum, average and standard deviation for the entire monitoring period. The salinity values are presented since lay people often relate more directly to salinity than specific conductance. Figures 2.2-24, 2.2-25, and 2.2-26 show the average value and standard deviation for specific conductance, temperature, and salinity, respectively, to facilitate a spatial visualization of the average automated surface water results.
Statistical files have been included in separate Excel files with the report.
Compared to the groundwater time series graphs, the surface water time series graphs show greater variability in the data, most of which is related to seasonal and meteorological conditions.
2-8
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 For example, in Biscayne Bay, the highest specific conductance values are near the end of the dry season and the lowest values are near the end of the wet season with minimum and maximum values ranging from 18,922 µS/cm (TPBBSW-10B) to 66,884 µS/cm (TPBBSW-1B).
The highest values in Biscayne Bay were recorded near the end of the very dry season in June 2011 at six of the seven Biscayne Bay stations. This equates to salinities throughout the project area in excess of 40 units on the practical salinity units (PSU) scale. Figure 2.2-27 compares surface water specific conductance values at Biscayne Bay stations. Station TPBBSW-14B (measured near the surface) consistently has the lowest water temperatures while TPBBSW-10B (measured near the surface) has the most variability. The specific conductance values in Biscayne Bay are within ranges observed at BBCW10 (SFWMD well located several miles north). In some instances, for example much of June 2011 specific conductance values were higher at BBCW10 than at Turkey Point Biscayne Bay stations.
The specific conductance values in the CCS show less seasonal variability than Biscayne Bay, but do change in response to rainfall events. Following a high rainfall event on October 8, 2011 (6.33 inches measured at TPM-1), the specific conductance values dropped 10% to 20% at all stations. This is similar to what occurred the previous year in September and November 2010 following several heavy rain events (7.34 and 4.36 inches, respectively, at TPM-1). The data show that there was no clear pattern of higher or lower specific conductance among the CCS stations. Variability in the results is often within the acceptable calibration limits of the instrument. Quarterly surface water sampling indicates the specific conductance values at all CCS stations are typically within 5% of each other. Over the entire monitoring period, the minimum and maximum CCS specific conductance values ranged from 50,528 µS/cm (TPSWCCS-4B) to 93,594 µS/cm (TPSWCCS-6B). The average specific conductance values in the CCS were consistently over 70,000 µS/cm in comparison to Biscayne Bay average values ranging between 43,433 µS/cm and 51,006 µS/cm for the monitoring period. Figure 2.2-28 compares time series specific conductance values between the CCS and several Biscayne Bay surface water stations. The specific conductance at TPSWC-5T is consistently higher than the Biscayne stations by over 20,000 µS/cm.
In the L-31E Canal stations, (TPSWC-1, TPSWC-2 and TPSWC-3), the specific conductance values were predominantly reflective of freshwater, however slightly more saline conditions were noted during several periods. The most notable period was near the end of the very dry season in June 2012 when maximum specific conductance values were 9,507 µS/cm (TPSWC-2B) and 22,776 µS/cm (TPSWC-3B). As is discussed in Section 3, there was not an incremental increase in tritium concentrations which might indicate regional Biscayne Bay influences instead of an influence from the CCS. Figure 2.2-29 compares time series specific conductance and temperature values for the different surface water stations in the L-31E Canal. Other spikes in specific conductance values were noted in TPSWC-3B in November 2011 and near the end of the dry season in 2012.
The specific conductance values in the two tidal stations TPSWC-4 and TPSWC-5 were more variable than the L-31E stations. TPSWC-4 is affected by releases from the S-20 structure and can transition from saline to fresh conditions quickly. Station TPSWC-5 reflects marine 2-9
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 conditions, but exhibited values in excess of those found in Biscayne Bay at the bottom. The water at TPSWC-5 is over 20 ft deep and is located at the end of this dead-end canal. The deep water depths and restrictions in flushing may contribute to the observed specific conductance values at this station.
The ID specific conductance values are affected by pumping of the ID ditch, which is conducted mostly in the dry season to maintain a seaward gradient between the L-31E Canal and the ID.
During non-pumping periods, the water in the ID is slightly saline to brackish, but during periods of heavy pumping, the water becomes saline in the pumped segments. In June 2011, the specific conductance values reached a peak at two ID stations with values in excess of 55,000 S/cm.
The effect was most pronounced at the bottom of TPSWID-2 where specific conductance values remained the highest for the longest duration. Specific conductance values in the ID were always below the values in the CCS and reflect a mixing of CCS water, freshwater, and Biscayne Bay water. Figure 2.2-30 compares time series specific conductance and temperature values for the different surface water stations in the ID. Figures 2.2-31 through 2.2-33 compare time series specific conductance and temperature values for the ID, L-31E, and CCS, at ID operation transect A stations (TPSWID-1, TPSWC-1, and TPSWCCS-1), transect C stations (TPSWID-2, TPSWC-2, and TPSWCCS-7), and transect E stations (TPSWID-3, TPSWC-3, and TPSWCCS-3), respectively. The figures show that CCS specific conductance values are highest in the CCS and lowest in the L-31E. The figures also show the temperature difference between the water bodies as the CCS cools from transect A to transect C. Discussion of the ID operation is included Section 6 of this report.
Water temperatures at all stations are greatly affected by meteorological conditions and reflect seasonal trends as expected. Ambient air temperature changes were quickly reflected in water temperatures and both Biscayne Bay and CCS stations tracked closely the overall ambient trend (Figure 2.2-34). In Biscayne Bay, average monthly water temperatures in January 2011 were around 20°C at all stations. In July 2011, average monthly water temperatures were near 31°C at all Biscayne Bay stations and the highest recorded 15-minute temperature was 35.2°C at TPBBSW-10B.
The water temperatures in the CCS also change with air temperature but are higher than other surface water locations. The CCS water is pumped from the intake side of the plant and routed through condensers to cool the power units. As the water passes through the condensers, it is heated and eventually discharged on the west side of the plant back into the CCS. The water temperatures on the CCS discharge side of the plant at TPSWCCS-1B are 7.5°C warmer on average for the entire monitoring period (June 20110 through June 2012) than at the intake side of the plant at TPSWCCS-6B. The range in temperatures varies monthly and CCS surface water temperatures are warmer in the summer months and cooler in the winter months. For example in September 2011, the average monthly CCS water temperatures ranged from 31.9°C at TPSWCCS-6B to 40.1°C at TPSWCCS-1. In January 2012, the average monthly CCS water temperatures ranged from 23.8°C at TPSWCCS-6B to 33.1°C at TPSWCCS-1B. There did not appear to be any temperature stratification at TPSWCCS-4 and TPSWCCS-6 since the water temperature was consistently the same at the top and bottom. However, at TPSWCCS-5, the 2-10
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 surface water temperatures were consistently higher at the top station. Figure 2.2-35 shows time series plots for stations in the CCS and illustrates the differences in temperature between stations on the discharge side of the plant (i.e., TPSWCCS-1B, TPSWCCS-7B) and the intake side of the plant (i.e., TPSWCCS-5 and TPSWCCS-6).
CSS water temperatures are regularly higher than the daily ambient air temperatures (Figure 2.2-34) and are often higher than daily maximum temperatures (Figure 2.2-36). This rarely occurs at other surface water stations. If there are temperature effects on Biscayne Bay from the warmer CCS waters, the effects would most likely be evident during the cooler months. Figure 2.2-36 shows the water temperatures from February to June 2011 for all the Biscayne Bay stations installed for the Uprate monitoring. Surface water temperatures from a SFWMD Biscayne Bay monitoring station several miles north of the site (BBCW-10) are included on Figure 2.2-36. The Turkey Point Biscayne Bay monitoring stations track very closely both with the SFWMD station and the maximum air temperatures recorded at TPM-1.
To help assess whether CCS water temperatures are affecting Biscayne Bay water temperatures, the differences between CCS and Biscayne Bay water temperatures and the differences between ambient air and Biscayne Bay water temperatures were examined (Figure 2.2-37). The results clearly demonstrate that CCS water temperatures, both on the intake and discharges sides, are warmer than Biscayne Bay water temperatures; there is only one instance where the plot exhibits a negative value for the difference between CCS and Biscayne Bay water temperatures (February 13, 2011; TPSWCCS TPBBSW4). This occurred when there was a major drop in the low ambient air temperature on February 13, and it appears the CCS water temperature responded more quickly to the daily low temperature. When compared to ambient air temperatures, Biscayne Bay water temperatures oscillate between being higher and lower than ambient air temperatures, particularly during the cooler months. This is to be expected as cold fronts move through and air temperatures both drop and recover more quickly, and to a greater degree, than water temperatures. Later in the year, mean ambient temperatures are almost exclusively lower than Biscayne Bay water temperatures. More importantly however, differences between the northern SFWMD surface water station (BBCW10) and both the ambient air temperatures and the CCS water temperatures follow the same pattern and are of the same magnitude as the FPL Biscayne Bay stations. These results suggest that air temperatures are driving water temperatures in Biscayne Bay and do not indicate any readily evident CCS water temperature effects in Biscayne Bay.
Water temperatures in the L-31E Canal (Figure 2.2-29) are on average cooler than those in Biscayne Bay. There is some temperature stratification in L-31 in part due to the canal depths and typically limited flow. The near surface water temperatures are almost always warmer than the bottom temperatures and the surface temperature exhibits more daily variability in response to air temperature changes. Near the end of the 2011 dry season, the bottom temperatures in TPSWC-3B were similar to the near surface water temperatures at that location and the timing coincides with the increase in specific conductance discussed above.
2-11
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 The time series plots (Figure 2.2-30) show that there were periods when the bottom water temperatures in the ID were greater than the surface water temperatures and those periods often corresponded with pumping of the ID and reflect some influence from the CCS. As a result, the average temperatures in the ID stations are higher than at the L-31E stations based on the entire monitoring period.
The water temperatures in the two tidal canal stations (TPSWC-4 and TPSWC-5) were also affected by air temperatures, but TPSWC-4 was also affected by discharges from S-20.
Generally the surface water temperatures at TPSWC-4 were higher than or similar to the bottom water temperatures; the effects of the CCS, if any, were hard to differentiate due to the variables that could affect water temperature. At TPSWC-5, the bottom water temperature was higher than the surface water temperature for months at a time.
2.3 WATER LEVELS 2.3.1 Instrumentation and Data Collection Methods Water levels provide insight into groundwater hydrology and groundwater and surface water interactions; levels are collected at all groundwater and most surface water stations for the Uprate Project monitoring effort. Only four water quality stations in Biscayne Bay do not have stage recorders. Per the Monitoring Plan, automated surface water quality monitoring stations co-located with groundwater monitoring well clusters in Biscayne Bay were to have surface water stage recorders. During the siting of the wells and surface water stations in Biscayne Bay, only one surface water quality station (TPBBSW-3) was co-located with a well cluster (TPGW-11); thus, one stage recorder was initially installed in Biscayne Bay. FPL later opted to install two additional stage recorders in Biscayne Bay (one each at the platforms associated with TPGW-10 and TPGW-14) to better assess groundwater and surface water interactions and tidal differences across the landscape.
Water pressures are measured at 15-minute intervals, and water levels are calculated from the pressure data. The results are typically transmitted on a regular basis via telemetry. LT500 and AT200 probes are used to record water pressure/levels. The LT500 only measures water pressure and temperature. This probe model is used in all automated groundwater well sites and is co-located with AT100 water quality units, but is placed near the surface to increase the accuracy of the pressure readings. At all automated surface water stations, AT200 probes are used for water levels since the probes measure both water pressure and water quality parameters. Both types of data are needed for surface water stations, and probes can typically be placed within 3 ft of the surface. Both probe models that measure water pressure have been deployed using a vented cable. The vented cable contains a tube that applies atmospheric pressure to the back of the pressure gauge. The instrument is programmed to automatically subtract this value from the measured pressure, reflected in the following formula:
Pgauge = Pabsolute - Patmosphere 2-12
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 Aside from being able to measure water quality parameters, the biggest difference between the AT200 probe and the LT500 probe is how specific gravity (SG) is handled. In the AT200 probe, an option exists to program a fixed density value or to auto-adjust water levels based on actual measured density. In the LT500 probe, only a fixed density value can be entered based on the water type (freshwater, brackish water, or saltwater). All LT500 probes are individually set to the fixed density value that best characterizes the water in the well. The AT200 probes are programed to automatically adjust water levels based on the measured density.
Both probes are programmed to record water levels based on a depth-to-water level setting.
Water levels are calculated in the instruments from the measured pressure based on the following formula:
WL = RL + (2.31 * (RP-MP)/SG) where:
WL - water level (measured in feet based on the North American Vertical Datum of 1988 (ft NAVD 88)
RL - reference water level (ft NAVD 88)
RP - reference pressure (pounds per square inch [psi])
MP - measured pressure (psi)
SG - specific gravity (unitless)
The SG in the above formula is the same as the density reading; thus, the values come directly from the instrument.
The reference level (RL) is a key component and is established in the field by using a water level indicator to measure the depth to water from the top of the well casing. Since the top of casing has been surveyed to an established datum (both NAVD 88 and National Geodetic Vertical Datum of 1929 [NGVD 29]), an elevation of the water is quickly determined by subtracting the depth to water from the top of casing. The resulting water level elevation is then entered into the probe as the reference level. The probe then automatically calculates the related pressure value, referred to as the reference pressure (RP). Subsequent pressure measurements recorded by the probe are relative to the reference pressure and its associated elevation.
The AT200 probes are cleaned in the same manner as described for the AT100 probes in the previous sections. The LT500 probes are wiped down with analyte-free water, with care not to damage the pressure transducer. The same care is used on the AT200 probes. While the pressure sensor cannot be calibrated, the resulting stage readings are verified. FPL has refined their approach over the course of the monitoring effort to improve the accuracy of the data. Currently, water level measurements are taken with a water level indicator prior to the removal of the LT500/AT200 probes for cleaning. An instantaneous reading from the probe is taken and compared to the water level indicator. Readings differing less than 0.1 ft are considered acceptable. The probe is then removed for cleaning, placed back in the well, and a similar comparison is made with the water level indicator and pressure reading. If needed, the reference 2-13
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 level is reset so the probe reading matches the water level reading to within 0.03 ft, which is the accuracy of the pressure sensor.
Similar to the AT100 probes, all LT500 and AT200 probes are factory-calibrated every 12 to 18 months. This effort was conducted systematically during regularly scheduled cleaning and calibration events between November 2011 and March 2012.
2.3.2 Results and Discussion 2.3.2.1 Groundwater As part of the validation process, water levels and pressures were plotted for the entire time period for each station. Sudden changes in water level were identified and checked against stage changes at other stations and against rainfall measurements. Time series plots of water levels in similar media and areas such as the CCS or in Biscayne Bay surface water were overlain and compared to one another to help identify potential problems with water level results. In addition, plots in groundwater and nearby or an overlying surface water body were overlain for similar comparisons. Careful attention was paid to periods when cleaning and calibration events occurred and for any activity that could alter the probe placement. Where stage data were available from a water level indicator or stage gauge readings, those values were compared to the reported water level measurements.
If water levels reported by the probe and field-measured values were off by more than 0.1 ft, the data were flagged for closer inspection. Also, shifts in data immediately following a calibration event or activity that could have impacted the probe placement were flagged if they were greater than 0.1 ft. The flagged data were reviewed further and, in some instances, it was clear there was an issue with an incorrect reference level and the data were corrected. In some instances, the cause for a discrepancy greater than 0.1 ft could not be established and the data were qualified as estimated; in other cases, the results were highly suspect in consideration of historical and surrounding station results, and the data were qualified as questionable. For difference of less than 0.1 ft, no correction or qualification of the data was applied.
It should be mentioned that the accuracy of the land-based station survey is better than 0.1 ft (typically within hundredths of a foot), but well locations in the Bay may have a lower level of accuracy since those stations could only be surveyed with GPS units. Thus, the survey accuracy limits should be taken into account when interpreting the results to hundredths of a foot or, in the case of the Biscayne Bay wells, to several tenths of a foot.
Figures 2.3-1 through 2.3-14 show time series graphs at all automated groundwater stations.
These graphs are based on refined validated data and exclude data that are questionable or recorded during a calibration event. Stage data were typically not qualified if the density values were suspect since the differences in the instrument-calculated density had little effect on the pressure reading/stage results, given the shallow depth of probe placement. All time-series graphs are based on actual measured levels, with the probes set to a representative density setting. The values do not reflect freshwater head equivalents. In order to facilitate closer 2-14
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data files in separate files in Excel with the report.
Some of the water level data reported in the first Semi-Annual Report (FPL 2011a) were revised based on a resurvey of the top of casing of groundwater wells. This updated information was included in an Errata to the 2011 Semi-Annual Report and changes were reflected in subsequent reports. Also for the first reporting period, FPL initially conducted a post-correction calculation to adjust the LT500 readings from a fixed density value to a measured value using the density from the AT100 located in the same well at depth. This post-correction used the above formula and was calculated similar to how an AT200 is programmed to calculate water levels. FPL subsequently determined (with SFWMD concurrence) that this procedure was unnecessary as the LT500 water levels readings were only affected by a few thousandths of a foot given the shallow placement of the LT500 probes. All water level data reported in the first Semi-Annual Report (FPL 2011a) were slightly readjusted based on a set density representative of that well. These adjustments have been reflected in subsequent reports.
A summary of the data collected and the patterns observed follows:
Water levels change very quickly in response to rainfall events. This is most evident in stations not significantly influenced by tides (TPGW-1, TPGW-2, TPGW-4 through TPGW-9, and TPGW-13). Typically, wherever there is a spike in water levels on the time series graphs, there is a corresponding rainfall event. Refer to Figures 2.3-1, 2.3-2, and 2.3-4 through 2.3-9 and 2.3-13.
At each well cluster, fluctuations in stage for all three depth intervals track closely, indicating a good hydrologic connection between intervals.
Water levels at stations in or immediately adjacent to Biscayne Bay (TPGW-3, TPGW-10, TPGW-11, TPGW-12, and TPGW-14) exhibited tidal influence at all three depths (Figures 2.3-3, 2.3-10, 2.3-11, 2.3-12 and 2.3-14). The amplitude of the tidal changes decreases across the landscape from north to south, similar to the decrease in surface water tidal amplitude discussed below. Thus, TPGW-10 has a higher range of water levels than TPGW-14.
Stations furthest from the coast (TPGW-7, TPGW-8, and TPGW-9) exhibit few water level differences among the shallow, intermediate, and deep wells (Figures 2.3-7, 2.3-8 and 2.3-9). These wells are all fresh per FDEP standards.
Wells located between the westerly most wells and the CCS, such as TPGW-4 and TPGW-5, have brackish water in the intermediate and deep zones overlain by much fresher water in the shallow zone. The shallow zone water elevations in these wells are always higher than the deep zone (Figures 2.3-4 and 2.3-5).
Closer to Biscayne Bay and the CCS, several well clusters have deep or intermediate zones with the highest elevation, such as TPGW-2. At this cluster, the deep and intermediate interval water levels alternate between having higher water levels (Figure 2.3-2).
2-15
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 At TPGW-13, the shallow and intermediate zones have nearly identical water levels and the deep zone is up to 0.4 ft lower.
For the land-based stations (tidal and non-tidal), the groundwater levels ranged up to 3 ft over the monitoring period. The non-tidal inland stations had the greatest seasonal range since they are affected more by drought and rainfall conditions. The lowest groundwater elevations at all the land-based stations, with the exception of well cluster TPGW-13, were reported in late May and early June 2011. This was near the end of an extended very dry season. The lowest groundwater elevations at well cluster TPGW-13 were recorded about a month earlier. The previous semi-annual report noted that the water levels at TPGW-2 were the lowest in early May 2011, but further review of the data indicates that the groundwater levels were lowest at this cluster in late May/early June 2011.
To provide insight into the differences in groundwater water levels over the landscape, time series plots from select stations are illustrated on Figures 2.3-15 to 2.3-18. Each figure represents a transect of well clusters. Many of these figures are self-explanatory and support the discussion above. Note that the water elevations of the non-tidal stations in Figures 2.3-15 and 2.3-16 are higher than the tidal stations, with the notable exception towards the end of the very dry season between April and mid-June 2011. Also note that TPGW-13S groundwater elevations on Figures 2.3-17 and 2.3-18 typically follow along the upper range of the tidal stations. Care should be used in drawing conclusions about groundwater flow directions based solely on the transect water levels since density effects have to be considered. Basically, denser water has more driving head than freshwater, and groundwater flow is influenced by these density differences. All the times series data that are reported reflect actual measured water levels and have not been converted to freshwater head equivalents.
To provide some initial insight into the groundwater and surface water interactions, Figures 2.3-19 through 2.3-21 illustrate the differences between surface water levels and groundwater levels in a nearby or co-located well(s) and where the densities in most wells and surface water stations are somewhat similar. Figure 2.3-19 shows a time series plot of surface water stage at TPSWCCS-2 and TPGW-13S and TPGW-13M. The results indicate that the water elevations at TPGW-13S are higher more often than at the corresponding surface water station in the CCS (TPSWCCS-2). However, there was at least one extended period during the dry season of 2011 when the CCS surface water levels were higher.
Figure 2.3-20 shows surface water levels in the CCS and groundwater levels in several wells immediately to the west. Figure 2.3-21 shows daily average surface water levels in TPBBSW-3 and TPGW-11, which is in Biscayne Bay. The daily average eliminates the hourly tidal fluctuations and facilitates a visual comparison between these stations. The plot illustrates that the groundwater levels in the Bay stations are directly influenced by surface water stage and the groundwater elevation at TPGW-11S is always higher than the co-located surface water station.
Further discussion of the groundwater elevations and implications is provided in Section 5 of this report.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 2.3.2.2 Surface Water Figures 2.3-22 through 2.3-39 show time series graphs at all surface water stations where data from automated stage recorders are available. These graphs are based on validated data and exclude data that are questionable or recorded during a calibration event when the log was running. All the time series graphs are based on actual levels and do not reflect freshwater head equivalents. In order to facilitate closer review of the time series results by the Agencies and allow them to adjust graphic scales presented herein and/or focus on a specific time interval, FPL has included the raw time series data files in separate files in Excel with the report.
The precision and accuracy of the surface water levels, particularly associated with stations affected by wave activity, may be slightly lower than for groundwater stations. While wave activity is dampened in stilling wells, some oscillation occurs that can affect the ability to consistently get precise verification readings with a water level indicator. Some data end up being qualified as estimated since a verification reading is off by more than 0.1 ft when in reality it may not need to be qualified. Also, the setting of the reference levels is affected by waves and can cause readings to be off.
As expected, diurnal water level variations were observed at all tidal-influenced stations, including those located in Biscayne Bay (north to south: TPBBSW-10, TPBBSW-3, and TPBBSW-14), as well as tidal canal stations (TPSWC-4 and TPSWC-5). The tidal range declines across the landscape from north to south (Figure 2.3-40). At TPBBSW-10, tide ranges during spring tide and neap tides can be over 2.0 ft and less than 0.5 ft, respectively.
The effect of rainfall is masked in most tidal stations; however, its effect is evident at TPSWC-4 since this station is downstream of S-20 discharges. Rainfall effects are also evident on all onshore stations where water level increases up to 1 ft have been observed following significant rainfall events in L-31E, the CCS, and the ID.
Water levels in the CCS vary spatially depending upon whether the station is located on the discharge or intake side of the canal. Water levels on the plant discharge side have lower ranges in variability (<1 ft at TPSWCCS-1) than stations on the discharge side (up to 4 ft at TPSWCCS-6). Also, water levels on the discharge side of the CCS are typically at least 1 ft higher than those on the CCS plant intake side (Figure 2.3-41). The difference in stage between the discharge and intake side increased during the 2011 and 2012 dry seasons and decreased during the wet season. It was noted that the water levels at all stations were very similar in late September and October 2010, October 2011 and February 2012 following a heavy rainfall event.
Water levels in the CCS and L-31E exhibit little response to tidal influences in Biscayne Bay surface water. Figure 2.3-42 provides a representative time series plot for spring tides on December 24, 2011, and March 9, 2012, which shows the lack of tidal response in the CCS and L-31E. This suggests the hydrogeologic connection with Biscayne Bay is limited or not as direct.

Care should be used in drawing conclusions about gradients solely based on the transect water levels since density effects have to be considered. Basically, denser water has more driving head than freshwater, and groundwater flow is influenced by these density differences. All the times series data that are reported reflect actual measured water levels and have not been converted to freshwater head equivalents.

Further discussion of the surface water elevations and implications is provided in Section 5 of this report.
2.4 METEOROLOGICAL DATA One of the key parameters of interest is the amount of precipitation in the CCS and surrounding areas. Rainfall timing, duration, and amounts provide some insight into the areas hydrology.
Additionally, meteorological data such as barometric pressure, wind speed, and light levels (i.e.,
photosynthetically active radiation [PAR]) are useful in determining water losses and gains in the CCS and in establishing a water budget.
A meteorological station (TPM-1) was set up in the middle of the CCS, co-located with TPGW-13 and TPSWCCS-2. Four additional rainfall gauges were set up in the vicinity of the plant to determine the spatial and temporal variability in rainfall on and offshore Turkey Point Plant. Locations of the rainfall and the meteorological stations are shown on Figure 2.4-1 and photos are included in Figure 2.4-2.
2.4.1 Instrumentation and Data Collection Methods Meteorological station TPM-1 consists of a weather transmitter (WXT520, Vaisala Inc., Helsinki, Finland) and a quantum sensor (190SA, Li-Cor Inc., Lincoln, Nebraska) attached to a datalogger (CR1000, Campbell Scientific Ltd., Logan, Utah) and telemetry system, mounted 15 ft above the ground surface; the range of parameters measured is listed in Table 2.4-1. Technical specifications on the instrumentation are provided in Appendix I of the QAPP (approved 12/2/2011, FPL 2011).
The four rainfall-only stations (TPRF-2, TPRF-4, TPRF-11, and TPRF-12) consist of tipping bucket rainfall gauges (TB-3, Hydrological Services Inc., Liverpool, NSW, Australia) connected to waterproof pendant dataloggers (#UA-004-64, Onset Computer Corporation, Bourne, Massachusetts). Data are manually downloaded from these stations at approximately bi-monthly intervals. Rainfall data from the gauges are event-based. The tipping buckets fill at 0.10 inch and the time of each tip of the bucket is recorded.
Additional rainfall data for this report were also provided by a previously existing FPL meteorological station located south of the CCS by the Sea Dade Canal (LU-South) and from an 2-18
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 existing rainfall station in the northern portion of the CCS (LU-NEast). The FPL meteorological station (LU-South) is similarly instrumented with a weather station (Climatronics Corp.,
Bohemia, New York), while the rainfall collector (LU-NEast) is a tipping bucket gauge.
Monitoring at TPM-1 was initiated on July 26, 2010, while the rainfall gauges were installed on November 12, 2010. At TPM-1, data are set to record at 15-minute intervals, although a reconfiguration of the initial setup by the manufacturer resulted in 30-minute data recording until March 7, 2011; although no data were lost, the data logger was then reset to record at 15-minute intervals after March 7, 2011. Data collected at this station are uploaded via telemetry to the FPL database on a daily basis.
In the past, issues with TPRF-12 not recording data occurred, but the unit has since been rewired and is now functional. Additionally, several of the other stations ran out of memory and did not record a full time period of data. These issues have been resolved, but gaps in data from the rainfall gauges remain.
2.4.2 Results and Discussion Rainfall and temperature (Figure 2.4-3), relative humidity and barometric pressure (Figure 2.4-3), wind speed and wind direction (Figure 2.4-4), and PAR (Figure 2.4-5) for TPM-1 are shown for the entire period.
Over the 704 days of continuous recordkeeping, (July 27, 2010, to June 30, 2012), 121 inches of rain were observed at TPM-1 (Table 2.4-2). The greatest monthly rainfall totals were observed in September 2010 (13.5 inches), followed by October 2011 (13.3 inches), and April 2012 (12 inches) (Figure 2.4-6 and Table 2.4-3). There were a total of 430 rainfall days with 39 days having recorded totals in excess of 1 inch in a calendar day (Table 2.4-4). The number of rain-days and the amount of rainfall was generally greatest during the wet season (May to November), with the driest months from December to February. The least amounts of rain in a month were observed in February 2011 (0.2 inches), November 2011 (0.3 inches) and December 2010 (0.5 inches).
During the first 11 months of monitoring, a severe drought was observed across Florida in the early half of 2011, as evidenced by the limited precipitation (6.1 inches total) from February to May 2011. The second year of monitoring (July 2011 to June 2012) was less dry, as evidenced by the higher amount of rainfall (81 7 inches). These inter-annual differences in precipitation between years (3.8 inches per month from August 2010 to June 2011 water year versus 6.8 inches per month from July 2011 to June 2012) underscore how rainfall variability can potentially influence the hydrology and ecology in coastal South Florida.
Rainfall frequency and periodicity is tied to the seasonal patterns of low pressure over South Florida during the wet season and is a consequence of cold front passage during the winter months. For example, the highest daily precipitation amounts were observed on September 29, 2010 (7.3 inches), and October 8, 2011 (6.3 inches). Both these events are tied to the passage of 2-19
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 low pressure systems over South Florida. The passage of cold fronts is usually evidenced by a drop in barometric pressure during the early winter days. Typically, the passage of a cold front is accompanied by higher wind speeds and decreased relative humidity following the rain event.
An example of this is shown in late 2010 by the first significant cold front of that season which occurred from November 3 to 5, resulting in a significant decrease in temperature (about 10°C),
relative humidity, and pressure.
Table 2.4-3 shows monthly rainfall totals from other rainfall stations around TPM-1. Although there was some variability among stations, the monthly rainfall totals in Biscayne Bay are consistently less than those on land while the totals at TPM-1 are higher than at most stations for most of the period of record. Nonetheless, the patterns at all stations are generally consistent across the months at the stations measured.
Air temperatures (at 15 ft above ground) in the middle of the CCS at TPM-1 ranged from 2.8°C to 33.8°C for the period of record, with an average of 25.5°C. The minimum temperature was observed on December 14, 2010, during the morning hours of a cold front passing through the area. The warmest temperature was observed on July 11, 2011, as July through September (monthly average > 29°C) are usually the warmest months of the year. Comparatively, the winter months of 2010/2011 (November to February) were colder than the similar time period of the following year (Figure 2.4-3).
Relative humidity at TPM-1 was an average of 71% during the period of recordkeeping. The patterns, however, were more variable in the winter months compared to the warmer months of April through June. Diurnal humidity patterns were influenced by broader seasonal patterns; for example, continued rainfall over several days in late September 2010 resulted in a few days (September 28 to 30) of 90% humidity while the passage of cold fronts (e.g., December 15, 2010) resulted in a humidity drop from 75% to 21% in 3.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />.
The prevailing wind directions from July 2010 through June 2012 were from the east and east-southeast, i.e., predominantly onshore (Figure 2.4-7). Average wind speed for the whole period, at 5 meters above ground, was 10 miles per hour (mph). The lull wind speeds averaged 6 mph, but several instances of strong wind gusts were observed, some in excess of 60 mph. The highest wind speed recorded at TPM-1 was observed during the passage of a frontal boundary on October 13, 2011, when a 134 mph wind gust was recorded. Similarly, wind speeds > 60 mph were seen on July 13, 2011, and April 26, 2012, with the approach of storm fronts. Forty-four percent of the time, the winds were between 7 to 11 meters per second (Figure 2.4-8).
Light levels show seasonal amplitude, with maximum light levels during the summer months and decreased light levels during the wintertime. Despite these overall trends, there were smaller patterns of decreased light levels as a consequence of cold front events (e.g., October 6 to 20, 2010) where several days of continuous cloudiness resulted in lowered light levels (Figure 2.4-5).

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 2.5 CCS FLOW METER DATA 2.5.1 Instrumentation and Data Collection Methods As previously discussed in the August 2011 Annual Report (FPL 2011b), automated Acoustic Doppler Flow Meters (ADFMs) were initially installed at three constrained-flow locations in the CCS and are referred to as the outflow, southerly, and inflow stations. The outflow station (TPFM-1) was set up to measure outflow of water from the plant entering the CCS; due to the canal setup, the station was located in the discharge feeder canal approximately 0.4 mile downstream of the plant, but prior to the flow dispersing into the CCS (Figure 1.1-4). The southerly station (TPFM-2) is located on the southern end of the CCS (south collector) where all water passes as it transitions from southerly to northerly flow (Figure 1.1-4). The inflow station was originally located about 0.4 mile from the intake back into the plant. The purpose of the flow meters was to help assess losses and gains in CCS water volume and flows as part of the water budget.
Each of the stations was equipped with a side-looking ADFM (Argonaut-SL 500, Sontek/YSI, Yellow Springs, Ohio) that emits three acoustic beams in a characteristic pattern (i.e., two horizontal beams separated by 50 degrees and one vertical beam) (Figure 2.5-1). Each station is powered using a solar-charged lead acid battery. All data are stored in a datalogger (CR800, Campbell Scientific, Logan, Utah) and remotely transferred to a permanent database daily via telemetry. The data loggers are programmed to record indexed velocity and flow every 15 minutes.
Platforms to support these ADFMs were constructed in the summer of 2010. The meters were subsequently installed by YSI following industry standard protocol (i.e., mount the sensor plumb
+/-2 degrees, no obstructions above or in front of the sensor, etc.). Stream gauging and indexing efforts were conducted with the final installation indexing efforts completed in November 2010.
Results of the initial indexing effort were provided in the August 2011 Annual Report (FPL 2011b).
Significant turbulence at TPFM-3 yielded poor data quality, and subsequent equipment failure resulted in removal of the flow meter in December 2010. This flow meter was repaired, but has not been reinstalled at TPFM-3 primarily due to issues with data quality, limitations in alternative inflow locations, and concerns of short-circuiting in the CCS. The issue of short-circuiting has been discussed with the Agencies. This issue limits the usefulness of the flow meters as originally envisioned. FPL collected temperature data to help confirm if short-circuiting of water from the discharge canals into the Grand Canal and return canals is occurring under the berms in the CCS. The greatest potential for underflow is the berm that separates the return Grand Canal and the discharge canal immediately adjacent to the Grand Canal, since the head differential between these two canals is the greatest. Results from this effort were presented to the Agencies on March 21, 2012, and indicated that some underflow may be occurring due to higher temperatures in the Grand Canal in comparison to the adjacent return canal to the east; however, the amount of underflow could not be determined.

FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 The other two meters recorded data through July/August 2011, but became inoperable and were pulled for troubleshooting in the field. TPFM-1 was not operating in June 2011, and FPL replaced that flow meter with the one that had been previously pulled and repaired from TPFM-
- 3. This flow meter recorded data for approximately one week (late June/early July 2011) before malfunctioning. At TPFM-2, data were collected until the mounting bracket broke in early August 2011. All flow meters were sent to YSI for diagnostics. These two meters were subsequently repaired, the mounting brackets were repaired, and the flow meters were reinstalled on May 29, 2012. Indexing was conducted during this reinstallation effort (on May 31) and the information is presented in Appendix F.
2.5.2 Results and Discussion This report includes data that has been recorded by all flow meters since initial installation on July 27, 2010. As the Agencies have expressed interest in these data, it has been post-corrected based on the initial indexing efforts and the results are included with the entire data set for the monitoring period. Figure 2.5-2 shows the available velocity and flow meter data that were collected during the pre-Uprate period.
The results show the variations in flow over time, with the most notable changes directly associated with major plant outages at the nuclear units. Velocity in the CCS ranges from 0.33 foot per second (ft/s) to 2.4 ft/s, with generally higher values observed at TPFM-2 relative to TPFM-1 (Figure 2.5-2). Average velocity is 0.89 +/- 0.19 ft/s (average +/- standard deviation) at TPFM-1 and 1.62 +/- 0.36 ft/s at TPFM-2. The channel is narrower at TPFM-2, hence resulting in greater velocities.
Flow rates of 1,032 cubic feet per second (ft3/s) to 4,367 ft3/s were observed in the CCS during the period of record. Average flow rates were 3,810 +/- 613 ft3/s at TPFM-1 and 2,507 +/- 520 ft3/s at TPFM-2. There was a significant positive correlation between the flow at both sites (FlowTPFM-2 = 0.8113(FlowTPFM-1) + 134.27; R² = 0.8708), as shown on Figure 2.5-3. Flow was higher at TPFM-1 relative to TPFM-2 (Figures 2.5-3 and 2.5-4) for 92.6% of the time although this pattern was sometimes reversed. Lower flow at TPFM-1 when simultaneously compared to TPFM-2 may in part be caused by plant operations when pumps are turned on and off or varying rainfall distribution over the CCS which can affect flow in different reaches of the CCS.
During an outage, less water is typically needed for cooling and thus less water is pumped through the plant. While the pumpage rates vary, depending on factors such as the specific reason for the outage and length of time, there are some typical considerations for the plants operating/shutdown conditions. Each nuclear unit has four circulating water pumps (CWPs; about 156,250 gallons per minute [gpm] each) and three intake cooling water pumps (ICWPs; about 16,000 gpm each). CCS water is pumped through the nuclear units for cooling. The nuclear units typically operate at full power with four CWPs and two ICWPs during operation.
During a planned nuclear plant refueling shutdown (every 18 months), the CWPs are turned off and the shutdown unit uses one or two ICWPs for plant cooling purposes. The CWPs are returned to service when the unit is ready to restart. During the major scheduled Unit 3 Uprate 2-22
FPL Turkey Point Comprehensive Pre-Uprate Monitoring Report for Units 3 & 4 Uprate Project - October 2012 Section 2 outage that started in March 2012, the CWPs were turned off. Figure 2.5-2 shows the drop in flow in late September 2010 through late October 2010 and again in mid-March 2011 through early May 2011 during refueling outages.
The two fossil units each have two CWPs (about 137,000 gpm each) and two open cooling water pumps (OCWPs; about 6,000 gpm each). Typically, during operation a fossil unit will use both CWPs and one or two OCWPs depending on cooling requirements. CCS water is pumped through the fossil units for cooling. Pumps in Unit 1 are periodically turned on to maintain its operational readiness as this unit is online during peak seasonal demand periods. However, Unit 2 is currently being used as a synchronous generator and is not producing megawatts (MWs; or steam heat). Unit 2 is typically using the OCWPs for cooling. The complete outage reports for this pre-Uprate period are in Appendix F.
Figures 2.5-5 and 2.5-6 illustrate representative flows over two separate weeks compared to tidal fluxes at TPBBSW-3 in Biscayne Bay. The graphs show daily patterns with a week. These flows are representative of values observed during a week of normal Turkey Point Nuclear Plant operations (January 23 through 30, 2011) and during the outage of Unit 4 (March 23 through 30, 2011). As Units 3 and 4 are the primary drivers of flow within the CCS, flows during the Unit 4 outage were approximately half of normal plant operations in March 2011 (Figure 2.5-2). When flow rates are compared against the tidal fluctuations in Biscayne Bay, there appears to be no relationship between the tidal conditions and the flow rates in the CCS.
