FPL Turkey Point Annual Post-Uprate Monitoring Report (Addendum) for Units 3 & 4 Uprate Project - May 2015

1. INTRODUCTION The Florida Power & Light Company (FPL) is submitting an addendum to the August 2014 Post-Uprate Monitoring Report, dated May 2015, for the Units 3 and 4 Uprate Project. This addendum 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 and modifications per the South Florida Water Management District (SFWMD) letters dated June 3, 2013, and July 17, 2013, followed by an email clarification dated July 23, 2013 (SFWMD 2009a, 2013a, b, c). While there is no public health or safety implication and all detected levels are far below U.S. Environmental Protection Agency (EPA) drinking water standards, the Monitoring Plan requires continued collection of tritium from groundwater and surface water, and meteorological and ecological data in and around Turkey Point to establish Post-Uprate conditions and determine the horizontal and vertical effects and extent of the cooling canal system (CCS) water and compare to Pre-Uprate conditions. For further details, refer to the Monitoring Plan and the Fifth Supplemental Agreement (SFWMD 2009a, b).

The purpose of this Addendum is to summarize the Post-Uprate tritium data from June 1, 2013, through May 31, 2014, as the United States Geological Survey (USGS) laboratory analyzing the samples had a backlog of approximately one year. Given the magnitude of this backlog, the Agencies asked FPL to prioritize reporting the quarterly ground- and surface water samples through March 2014, and provide an addendum report when all four quarters of data became available.

Therefore, this report contains tritium data from the quarterly ground and surface water sampling events (June, September, December 2013; March 2014), as well as the rainfall (June 2013) and monthly evaporation pan data (June and July 2013); all other quarterly rainfall (i.e., from September 2013 onwards) and evaporation pan tritium data (August 2013 onwards) are still pending. Porewater tritium results from the ecological transects are also still pending for the reporting period.

2. GROUNDWATER AND SURFACE WATER SAMPLING Samples were collected at frequencies and locations per the Monitoring Plan and the Quality Assurance Performance Plan (QAPP) during this Post-Uprate monitoring period (SFWMD 2009a; FPL 2013b). All analyses were conducted by the USGS Tritium Laboratory (Menlo Park, California) per analytical methods described in the project QAPP.

In brief, sampling was conducted at 19 groundwater locations and 18 surface water stations.

Each of the 19 Uprate project groundwater stations consists of a cluster of three separate wells discretely screened at different depth intervals and samples are collected from those depth intervals. The five historical wells (L-3, L-5, G-21, G-28, and G-35) which are screened across most of the well depth have two samples that are collected from different depths (18 feet and 58 feet below top of casing). Surface water stations are sampled at two depths (i.e., 1 foot from the top and 1 foot from the bottom) with the exception of the shallow Biscayne Bay and CCS sites where only a single bottom sample is collected. In June 2013, after review by the Agencies, several surface water sites (TPBBSW-1B, TPBBSW-2B, TPSWCCS-6 (B and T), TPSWCCS-4B, and TPSWCCS-5B) were eliminated.

All of the other quarterly analytical data from this reporting period have been previously reported, so the data presented in this report reflect updated files including tritium data for completeness (FPL 2014b, 2015). A summary of analytical data is presented in this section along with the updated accompanying Data Usability Summaries (DUS) (see Tables 2.1-1 to 2.1-8 and Appendix A).

2.1 GROUNDWATER TRITIUM Groundwater samples were collected in accordance with the QAPP and based on the Florida Department of Environmental Protection Standard Operating Procedures. Tables 2.1-1 through 2.1-8 provide the field, ionic, and nutrient data for completeness and the new tritium data for June 2013 to March 2014 For most stations, tritium did not differ within sites between the Pre-Uprate and Post-Uprate periods. Tritium values that were low remained low, while the sites that had higher tritium values continued to reflect those patterns. The following wells displayed an increasing trend in tritium concentration or a Post-Uprate value was detected outside the Pre-Uprate range: TPGW-10D, -11M, -11D, -13S, and -14D (see Figure 2.1-1 and Table 2.1-9). At the TPGW-10, -11, and -14 wells, tritium values were noticeably higher in the Interim Operating Period (IOP) and in some wells, tritium values have remained at the higher levels through March 2014. In TPGW-10M, the values increased during the IOP and were higher in June 2013, but the values have since returned to Pre-Uprate levels from September 2013 onwards (see Table 2.1-9).

2-1

FPL Turkey Point Annual Post-Uprate Monitoring Report (Addendum) for Units 3 & 4 Uprate Project - May 2015 TPGW-13S showed the opposite trendthe March 2014 value in this well was approximately half than in the previous quarter.

Overall, the comparison of Pre-Uprate (June 2010 to December 2011) and Post-Uprate (June 2013 to March 2014) plan view isopleths showed the same general trends landward and limited increase in tritium eastward at depth (see Figure 2.1-2).

2.2 SURFACE WATER Surface water samples were collected in accordance with the QAPP and based on the Florida Department of Environmental Protection Standard Operating Procedures. Tables 2.2-1 through 2.2-4 provide the field, ionic, and nutrient data for completeness and the new tritium data for June 2013 to March 2014. Most Post-Uprate surface water sample values were within the same range as Pre-Uprate data (see Table 2.2-5 and Figure 2.2-1). However stations TPSWCCS-2, TPSWCCS-3 and TPSWCCS -4 had higher values than previously recorded and the sampled collected from TPSWCCS-2 in March 2014 had the highest value observed within the CCS over the whole monitoring period (see Figure 2.2-1); this shallow site is located in the middle of the CCS and the value was most likely reflective of evaporative enrichment of the water during its travel path along the CCS.

Surface water values are more variable than groundwater values, and the range of values differs depending on the waterbody. Values in the CCS are influenced by localized seasonal variability and are also a reflection of plant operations and broader regional climatic conditions. The highest surface water values are generally observed at the end of the dry season, either in March or June, of each year. In addition, surface waterbodies are more directly affected by atmospheric deposition and vapor exchange of tritium.

2.3 RAINFALL FPL measures rainfall quarterly at seven stations in and around the CCS. However, June 2013 was the only quarter that rainfall tritium results were available for the Post-Uprate period (see Table 2.3-1). The rainfall values were within range of data previously observed (see Figure 2.3-1). Sites closest to the CCS had the highest values, and this generally occurred in the dry season in March although it can be in June depending on the regional climatic conditions and if the wet season has begun (see Figure 2.3-1). June 2013 values were lowest at TPRF-7 and -8 and highest at TPRF-2 (28.7 picocuries per liter [pCi/L]; see Table 2.3-2).

2.4 EVAPORATION PANS Five evaporation pans were sampled and refilled each month. Tritium data from evaporation pans was only available for June and July 2013 due to the USGS backlog (see Table 2.4-1).

These Post-Uprate results are within range and consistent with data from the same time range of previous years. Evaporation pan data are a function of meteorological conditions (e.g., rainfall, relative humidity, and wind speed and direction) overlying the pan. The water in these pans is 2-2

FPL Turkey Point Annual Post-Uprate Monitoring Report (Addendum) for Units 3 & 4 Uprate Project - May 2015 subject to atmospheric vapor exchanges of tritium and rainfall. Due to the presence of the CCS, the vapor content of tritium in the atmosphere is higher closer to the CCS than farther away.

Consequently, data from TPEVP-13 and TPEVP-2 are always higher than from the other three stations (i.e., TPEVP-3, -5, and -12) due to their proximity to the plant (see Figure 2.4-1, Table 2.4-2). As noted in the Pre-Uprate report, values in excess of 20 pCi/L (Agencies background concentration for tritium) are found several miles west of the plant.

SUMMARY

In summary, the patterns observed in tritium values during the Post-Uprate period are generally similar to the historical Pre-Uprate period or previously reported. Additional observations include:

All tritium levels are well below U.S. EPA safe drinking water standards.

Beyond a few sites, there has been no landscape-scale change in the tritium values.

Surface water stations and rainfall tritium are more variable than the groundwater data depending on the season and regional climatic conditions. Samples within the CCS are also affected by plant operations.

Evaporation pan data are affected by proximity to the CCS and meteorological conditions in and around the area.

FPL Turkey Point Annual Post-Uprate Monitoring Report (Addendum) for Units 3 & 4 Uprate Project - May 2015

1. INTRODUCTION The Florida Power & Light Company (FPL) is submitting an addendum to the August 2014 Post-Uprate Monitoring Report, dated May 2015, for the Units 3 and 4 Uprate Project. This addendum 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 and modifications per the South Florida Water Management District (SFWMD) letters dated June 3, 2013, and July 17, 2013, followed by an email clarification dated July 23, 2013 (SFWMD 2009a, 2013a, b, c). While there is no public health or safety implication and all detected levels are far below U.S. Environmental Protection Agency (EPA) drinking water standards, the Monitoring Plan requires continued collection of tritium from groundwater and surface water, and meteorological and ecological data in and around Turkey Point to establish Post-Uprate conditions and determine the horizontal and vertical effects and extent of the cooling canal system (CCS) water and compare to Pre-Uprate conditions. For further details, refer to the Monitoring Plan and the Fifth Supplemental Agreement (SFWMD 2009a, b).

The purpose of this Addendum is to summarize the Post-Uprate tritium data from June 1, 2013, through May 31, 2014, as the United States Geological Survey (USGS) laboratory analyzing the samples had a backlog of approximately one year. Given the magnitude of this backlog, the Agencies asked FPL to prioritize reporting the quarterly ground- and surface water samples through March 2014, and provide an addendum report when all four quarters of data became available.

Therefore, this report contains tritium data from the quarterly ground and surface water sampling events (June, September, December 2013; March 2014), as well as the rainfall (June 2013) and monthly evaporation pan data (June and July 2013); all other quarterly rainfall (i.e., from September 2013 onwards) and evaporation pan tritium data (August 2013 onwards) are still pending. Porewater tritium results from the ecological transects are also still pending for the reporting period.

2. GROUNDWATER AND SURFACE WATER SAMPLING Samples were collected at frequencies and locations per the Monitoring Plan and the Quality Assurance Performance Plan (QAPP) during this Post-Uprate monitoring period (SFWMD 2009a; FPL 2013b). All analyses were conducted by the USGS Tritium Laboratory (Menlo Park, California) per analytical methods described in the project QAPP.

In brief, sampling was conducted at 19 groundwater locations and 18 surface water stations.

Each of the 19 Uprate project groundwater stations consists of a cluster of three separate wells discretely screened at different depth intervals and samples are collected from those depth intervals. The five historical wells (L-3, L-5, G-21, G-28, and G-35) which are screened across most of the well depth have two samples that are collected from different depths (18 feet and 58 feet below top of casing). Surface water stations are sampled at two depths (i.e., 1 foot from the top and 1 foot from the bottom) with the exception of the shallow Biscayne Bay and CCS sites where only a single bottom sample is collected. In June 2013, after review by the Agencies, several surface water sites (TPBBSW-1B, TPBBSW-2B, TPSWCCS-6 (B and T), TPSWCCS-4B, and TPSWCCS-5B) were eliminated.

All of the other quarterly analytical data from this reporting period have been previously reported, so the data presented in this report reflect updated files including tritium data for completeness (FPL 2014b, 2015). A summary of analytical data is presented in this section along with the updated accompanying Data Usability Summaries (DUS) (see Tables 2.1-1 to 2.1-8 and Appendix A).

2.1 GROUNDWATER TRITIUM Groundwater samples were collected in accordance with the QAPP and based on the Florida Department of Environmental Protection Standard Operating Procedures. Tables 2.1-1 through 2.1-8 provide the field, ionic, and nutrient data for completeness and the new tritium data for June 2013 to March 2014 For most stations, tritium did not differ within sites between the Pre-Uprate and Post-Uprate periods. Tritium values that were low remained low, while the sites that had higher tritium values continued to reflect those patterns. The following wells displayed an increasing trend in tritium concentration or a Post-Uprate value was detected outside the Pre-Uprate range: TPGW-10D, -11M, -11D, -13S, and -14D (see Figure 2.1-1 and Table 2.1-9). At the TPGW-10, -11, and -14 wells, tritium values were noticeably higher in the Interim Operating Period (IOP) and in some wells, tritium values have remained at the higher levels through March 2014. In TPGW-10M, the values increased during the IOP and were higher in June 2013, but the values have since returned to Pre-Uprate levels from September 2013 onwards (see Table 2.1-9).

2-1

FPL Turkey Point Annual Post-Uprate Monitoring Report (Addendum) for Units 3 & 4 Uprate Project - May 2015 TPGW-13S showed the opposite trendthe March 2014 value in this well was approximately half than in the previous quarter.

Overall, the comparison of Pre-Uprate (June 2010 to December 2011) and Post-Uprate (June 2013 to March 2014) plan view isopleths showed the same general trends landward and limited increase in tritium eastward at depth (see Figure 2.1-2).

2.2 SURFACE WATER Surface water samples were collected in accordance with the QAPP and based on the Florida Department of Environmental Protection Standard Operating Procedures. Tables 2.2-1 through 2.2-4 provide the field, ionic, and nutrient data for completeness and the new tritium data for June 2013 to March 2014. Most Post-Uprate surface water sample values were within the same range as Pre-Uprate data (see Table 2.2-5 and Figure 2.2-1). However stations TPSWCCS-2, TPSWCCS-3 and TPSWCCS -4 had higher values than previously recorded and the sampled collected from TPSWCCS-2 in March 2014 had the highest value observed within the CCS over the whole monitoring period (see Figure 2.2-1); this shallow site is located in the middle of the CCS and the value was most likely reflective of evaporative enrichment of the water during its travel path along the CCS.

Surface water values are more variable than groundwater values, and the range of values differs depending on the waterbody. Values in the CCS are influenced by localized seasonal variability and are also a reflection of plant operations and broader regional climatic conditions. The highest surface water values are generally observed at the end of the dry season, either in March or June, of each year. In addition, surface waterbodies are more directly affected by atmospheric deposition and vapor exchange of tritium.

2.3 RAINFALL FPL measures rainfall quarterly at seven stations in and around the CCS. However, June 2013 was the only quarter that rainfall tritium results were available for the Post-Uprate period (see Table 2.3-1). The rainfall values were within range of data previously observed (see Figure 2.3-1). Sites closest to the CCS had the highest values, and this generally occurred in the dry season in March although it can be in June depending on the regional climatic conditions and if the wet season has begun (see Figure 2.3-1). June 2013 values were lowest at TPRF-7 and -8 and highest at TPRF-2 (28.7 picocuries per liter [pCi/L]; see Table 2.3-2).

2.4 EVAPORATION PANS Five evaporation pans were sampled and refilled each month. Tritium data from evaporation pans was only available for June and July 2013 due to the USGS backlog (see Table 2.4-1).

These Post-Uprate results are within range and consistent with data from the same time range of previous years. Evaporation pan data are a function of meteorological conditions (e.g., rainfall, relative humidity, and wind speed and direction) overlying the pan. The water in these pans is 2-2

FPL Turkey Point Annual Post-Uprate Monitoring Report (Addendum) for Units 3 & 4 Uprate Project - May 2015 subject to atmospheric vapor exchanges of tritium and rainfall. Due to the presence of the CCS, the vapor content of tritium in the atmosphere is higher closer to the CCS than farther away.

Consequently, data from TPEVP-13 and TPEVP-2 are always higher than from the other three stations (i.e., TPEVP-3, -5, and -12) due to their proximity to the plant (see Figure 2.4-1, Table 2.4-2). As noted in the Pre-Uprate report, values in excess of 20 pCi/L (Agencies background concentration for tritium) are found several miles west of the plant.

SUMMARY

In summary, the patterns observed in tritium values during the Post-Uprate period are generally similar to the historical Pre-Uprate period or previously reported. Additional observations include:

All tritium levels are well below U.S. EPA safe drinking water standards.

Beyond a few sites, there has been no landscape-scale change in the tritium values.

Surface water stations and rainfall tritium are more variable than the groundwater data depending on the season and regional climatic conditions. Samples within the CCS are also affected by plant operations.

Evaporation pan data are affected by proximity to the CCS and meteorological conditions in and around the area.

1 TPEVP-13A was not set up until April 2011; the first samples were collected in May 2011.

2 TPEVP-Pumped-Source is only collected when water transported in the water bladders is used to fill pans at TPEVP-5 on a different day. After April 2012, a faster refilling method was used and all site re-filling was completed within a day.

3 Pans were full in August and not refilled; therefore, there was no Source Water. TPEVP-5 was visited 7/29/11 instead of 8/2/11 (for all other sites).

4 Pans were full in November and not refilled; therefore, there was no Source Water for that month.

5 Pans were dry so no samples were taken.

P - Samples collected but results not available.

NA - Sample not collected, data not available.

Key:

= Data available.

NA = Not available.

P = Pending.
