SUMMARY

Florida Power & Light Company (FPL) successfully initiated operations of the Turkey Point Recovery Well System (RWS) on May 15, 2018. This approved groundwater remediation system is designed to intercept, capture, and retract hypersaline groundwater (with a chloride concentration greater than 19,000 milligrams per liter [mg/L]) located to the west and north of FPL's property without creating adverse environmental impacts. FPL has prepared this RWS Startup Report, as outlined in letters from Miami Dade County Department of Regulatory and Economic Resources (MDC) dated September 29, 2016, and May 15, 2017. This RWS Startup Report includes baseline groundwater monitoring data and Continuous Surface Electromagnetic Mapping (CSEM) survey results collected prior to startup of the RWS, data collected during the first quarter of operation (May 15, 2018, through August 15, 2018), and information on RWS design and operation.

During this period, the system operated as designed, with the pumps collectively running approximately 96% of the time. Measured drawdown associated with the operation of the RWS was de minimis and has not resulted in adverse impacts to wetlands or water resources. There were no operations of the interceptor ditch (ID) pumps during the first quarter ofRWS operations.

During the first quarter of RWS operations, approximately 1.4 billion gallons of hypersaline groundwater containing 577 million pounds of salt were removed from the Biscayne Aquifer.

There are no proposed changes to the RWS operations at this time.

2. RECOVERY WELL SYSTEM The Turkey Point RWS includes 10 groundwater recovery wells, a conveyance pipeline system, and a deep injection well (DIW) (Figure 2.1-1). The recovery wells are designed to extract hypersaline groundwater preferentially along the base of the Biscayne Aquifer. The shallow and intermediate zones of the Biscayne aquifer in each recovery well are cased off, thereby allowing hypersaline groundwater to be pulled from the high-flow zones. of the lower portion of the Biscayne aquifer. Accordingly, recovery well depths vary from 90 to 105 feet (ft) below ground surface, with wells casings set approximately 25 ft above the bottom. Table 2.1-1 provides the location of each recovery well and construction details (i.e., depth, casing sizes, borehole diameter).

Each recovery well is equipped with a line shaft turbine pump powered by a 150-horsepower electric motor with a capacity of approximately 2 million gallons per day (mgd). The current R WS has a permitted withdrawal allocation of 15 mgd, with each well set to withdraw 1.5 mgd ofhypersaline groundwater. A Supervisory Control and Data A~quisition (SCA.DA) system provides centralized operation of the RWS and has the capability to monitor and regulate individual well withdrawal rates and maintain total extraction capacity in the event of individual well fluctuations based on manual or programed operational protocols. Figure 2.1-2 shows a typical recovery well with pump motor and valves. Further details regarding the recovery wells, pumps, motors, and appurtenances are found in Appendix A. Geophysical logs for the recovery wells are provided in Appendix B.

Hypersaline groundwater pumped from each recovery well is routed through a 14-inch-diameter high-density polyethylene (HDPE) pipe to a main 28-inch header pipeline. The header pipeline network connecting all of the RWS extraction wells to the DIW are approximately 9 miles long (Figure 2.1-1 ). All piping is buried for protection; a photograph of the header pipeline during construction is shown on Figure 2.1-3. Further details on the pipeline system and specifications are included in Appendix A.

The DIW is located near the center of the Cooling Canal System (CCS) (Figure 2.1-1). The DIW is a 24-inch-diameter permitted Underground Injection Control (UIC) non-hazardous Class I industrial wastewater disposal well (Permit No. 0293962-004-U0/11) constructed to a depth of 3,230 ft below ground surface into the regionally confined Boulder Zone. Figure 2.1-4 shows the DIW wellhead, appurtenances, and well construction details. Monitoring of the DIW is conducted in part, via a dual-zone monitoring well, pursuant to permit conditions (Figure 2.1-5).

The assessment of progress made in meeting the objectives of the FDEP Consent Order and the MDC Consent Agreement hypersaline groundwater remediation is informed, in part, by a series of existing and newly added monitoring wells. New RWS monitoring well clusters TPGW-17, TPGW -18, and TPGW -19 were constructed west of the CCS pursuant to paragraph 17 .d.iv. of the Consent Agreement to monitor progress of the retraction of the hypersaline plume.

Recovery Well System separate wells were installed at each location: a shallow well (S), located in the upper high-flow zone of the Biscayne aquifer; an intermediate depth well (M) in the middle high-flow zone; and a deep well (D) along the base of the aquifer. 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. Screen depths were established, with screen lengths varying from 2 to 5 ft, based on site conditions, to ensure high-flow zones at each depth were being monitored.

Appendix C provides further details on these three new monitoring well clusters.

All monitoring wells, recovery wells and the DIW are equipped with automated probes (In Situ LT500 and ATlOO probes or Hach 3700) that allow the collection of hourly water level, temperature, specific conductivity, salinity, and density data. In addition, the monitoring wells, RWS extraction wells, and inflows into the DIW are sampled for select analytic water quality data ranging from weekly to monthly frequencies. All data required under the provisions of the MDC Consent Agreement are collected, processed, and quality controlled under the approved Turkey Point Quality Assurance Project Plan (QAPP). Provisional quality assurance (QA)/quality control (QC) data and associated documentation are posted on an FPL database and provided to MDC, FDEP, and the South Florida Water Management District (SFWMD) in annual reports. Provisional water quality and water level data collected during the first quarter ofRWS operations are discussed in Section 3 of this report.

3. RECOVERY WELL SYSTEM BASELINE DATA AND FIRST QUARTER OF OPERATION FPL conducted a baseline CSEM survey and collected groundwater data from the recovery wells and select monitoring wells prior to RWS startup (baseline groundwater data) and for the first quarter of operation, consistent with the MDC letters dated September 29, 2016, and May 15, 2017. This section presents the baseline information, a summary ofRWS monitoring data and operation, and a discussion of influence of the RWS on groundwater and impacts to adjacent wetlands during the first quarter of operation.

3.1 Baseline Monitoring Results FPL collected baseline groundwater samples between March 13, 2018, and April 3, 2018, from new monitoring well clusters TPGW-17, TPGW-18, and TPGW-19, historical well clust~rs TPGW-1, TPGW-2, TPGW-4, TPGW-5, TPGW-7, and TPGW-12, and historical individual wells TPGW-L3, TPGW-L5, TPGW-G21, and TPGW-G28 (Figure 3.1-1). Field parameters (temperature, specific conductance, salinity, density, and total dissolved solids [TDS]) were measured and samples were collected for laboratory analysis of tritium and chloride at each of the wells/well clusters. Groundwater levels were also measured during sampling. The results are presented in Table 3.1-1. Groundwater sampling logs from the March 2018 sampling event are provided in Appendix D of this report. Data usability summary (DUS) reports for the event are provided in Appendix E, and the Level IV laboratory reports are included in Appendix F.

Samples were collected at discrete screen intervals from the shallow, intermediate, and deep wells at TPGW-1, TPGW-2, TPGW-4, TPGW-5, TPGW-7, TPGW-12, TPGW-17, TPGW-18, and TPGW-19 well clusters. The historical individual wells, TPGW-L3, TPGW-L5, and TPGW-G21, are continuously screened across the formation; the exception is TPGW-G28 which is hard-cased to 18 ft below the top of casing. These individual well samples were collected at 18 ft and 58 ft below top of casing. Samples from the groundwater well clusters were collected using dedicated tubing, and all samples were collected per the methods outlined in the QAPP (FPL 2013) and FDEP Standard Operating Procedures (SOPs).

All sites, besides TPGW-17, TPGW-18, and TPGW-19, have a long-term record of quarterly water quality data dating back to 2010. There are also automated water elevation, specific conductance, temperature, and salinity data collected at 15-minute to 1-hour intervals since 2010 except for the three new well clusters which have a shorter period of record and TPGW-L3, TPGW-L5, TPGW-G21, and TPGW-G28 which are not equipped with automated instrumentation. Table 3.1-2 shows baseline groundwater elevations at a specific point in time from the different monitoring locations. As the individual wells do not have automated instrumentation, the closest temporal field measurements from these sites were used.

Recovery Well System Baseline Data and First Quatter of Operation Hourly automated groundwater water level data show groundwater levels are influenced by tidal cycles to varying degrees as well as rainfall, dry periods, and density of the waters within the sampled horizon. Accordingly, area groundwater elevations vary temporally (throughout each day due to tidal influences as well as daily, weekly, and seasonally) and vertically (within the

. aquifer due to variations in salinity) at any given sample site.

3.2 CSEM Baseline Survey As outlined in Section 3b of the MDC letter dated May 15, 2017, and paragraph 29(a) of the FDEP Consent Order, FPL conducted a baseline CSEM survey to map the extent and orientation of the hypersaline groundwater plume west and north of the Turkey Point Plant. The survey was conducted in late March/early April 2018 (within 60 days ofRWS startup) and encompassed approximately 30 square miles to the west and north of the CCS, including an area beneath the edge of the CCS and the FPL property boundary and an area north and northwest of the CCS.

The survey was performed using a helicopter equipped with a transient electromagnetic method (TEM) transmitter and receiver system. The TEM system measures the bulk resistivity of specific depths of earth materials and associated groundwater. Chloride concentrations of groundwater were inferred from the resistivity values derived from the TEM data via the process illustrated in Fitterman and Prinos (2011) as described in the PTN Cooling Canal System electromagnetic geophysical survey report (ENERCON 2016). 3D voxels (discrete cells of specific chloride concentration) were created based on the vertical and horizontal discretization of the TEM data and extend from the land surface to the base of the Biscayne Aquifer (Fish and Stewart 1991) and west and north of the FPL property, as defined in the MDC Consent Agreement. The report summarizing the 2018 baseline survey and results is provided in Appendix G.

In addition to mapping groundwater with chloride concentrations greater than> 19,000 milligrams per liter (mg/L), FPL evaluated the CSEM method to identify a reliable lower limit of chloride estimation for mapping. As the chloride ion content of pore waters in the Biscayne Aquifer decreases, the influence of porosity variations on the bulk conductivity of the bedrock/pore water combination increases. At some lower limit of chloride ion content, the geologic noise from porosity variations becomes too large for reliable mapping of chloride ion content using the CSEM method. To determine the lower limit for reliable mapping of chloride ion values, the accuracy of predicting pore water chloride ion values for waters with chloride levels <19,000 mg/L was compared to the accuracy of mapping chloride for waters> 19,000 mg/L. The evaluation indicated that the average CSEM chloride ion prediction error is about the same for pore waters with chloride ion contents > 10,000 mg/L as for pore waters with chloride ion contents> 19,000 mg/L. However, prediction accuracy decreases significantly for pore water chloride ion contents <10,000 mg/L. Based on this analysis, the reliable lower limit of the CSEM TEM survey for mapping chloride ion content within the Biscayne Aquifer is 10,000 mg/L.

The CSEM survey determined that the maximum westward extent of the hypersaline groundwater, as defined by chloride concentrations in excess of 19,000 mg/L west and north of the FPL property (MDC September 29, 2016), is approximately 16,000 ft west of the western 3-2

Recovery Well System Baseline Data and First Quarter of Operation boundary of the CCS at a depth of 47 to 55 ft. The plume does not extend as far west at shallower and deeper depths, indicating that the hypersaline plume is wedge-shaped, with the tip of the wedge at about 55 ft below land surface. At both shallower and deeper depths, the plume does not extend as far west. The presence of hypersaline water at the base of the Biscayne Aquifer (87.0 to 99.4 ft below land surface) extends only about 5,600 ft westward from the CCS.

The baseline volume of the material with chloride concentrations greater than 19,000 mg/L within the compliance area west and north of the FPL property as identified in the MDC Consent Agreement is estimated to be 450,493,000 cubic meters (m 3). The estimate sums the volume of each model cell within the 3D voxel model having an estimated chloride concentration of 19,000 mg/Land greater.

3.3 First Quarter of Operation Monitoring Results FPL collected samples from the recovery and monitoring wells that were used for the baseline sampling consistent with the startup monitoring included in the MDC May 15, 2018, letter. Field parameters (temperature, specific conductance, salinity, density, and TDS) and samples for chloride analysis were collected weekly for the first month of operation (startup through June 15, 2018) and then once a month in July and August 2018. Samples from the recovery wells were collected from dedicated sampling ports, while samples from groundwater monitoring wells were collected using peristaltic pumps, with most wells having dedicated sample tubing. All samples were collected per the methods outlined in the QAPP (FPL 2013) and FDEP SOPs provided in Chapter 62-160, Florida Administrative Code (F.A.C.).

The chloride results from the recovery wells during the first quarter sampling period show chloride levels in each of the recovery wells were stable, with minor fluctuations within a narrow range (Table 3.3-1). During the first quarter, chloride values typically varied by less than 5%;'

however, RWS-1 did exhibit more variability than the other wells. Recovery well RWS-1 also had the lowest overall average chloride concentration (22,857 mg/L), while RWS-5 had the highest average concentration (31,086 mg/L). Chloride concentrations in the monitoring wells (Table 3.3-2) showed a similar pattern as the recovery wells i.e. most of the chloride concentrations in the monitoring wells fluctuated within a narrow range of values. The sampling logs for the first quarter of monitoring are provided in Appendix D. The DUS reports are provided in Appendix E, and the Level IV laboratory reports are included in Appendix F.

Automated water level and water quality (specific conductance, salinity, temperature, and density) data were recorded at all well clusters (TPGW-1, TPGW-2, TPGW-4, TPGW-5, TPGW-7, TPGW-12, TPGW-17, TPGW-18, and TPGW-19). The automated water level and salinity data during the first quarter of operations showed increases in water levels and commensurate reductions in salinity levels in the shallow monitoring horizon of area monitoring wells, which is most likely the result of freshening by rainfall. Salinity trends in the middle and deep monitoring horizons were mostly stable, with some sharp shifts associated with periodic probe cleaning and recalibration.

Recovery Well System Baseline Data and First Quarter of Operation 3.4 System Operation and Optimization During First Quarter The amount ofhypersaline water than can be withdrawn from the Biscayne Aquifer and disposed into the Bolder Zone is constrained by two permits. The Consumptive Use Permit from SFWMD provides an annual withdrawal allocation of 5,475 million gallons an_d a maximum monthly allocation of 465 million gallons. This operational peak capacity is constrained by the UIC permit from FDEP that limits the maximum injection rate to 10,826 gallons per minute (gpm) and a maximum injection volume of 15.59 mgd down the DIW. As described earlier, the SCADA system incorporates operational locks to ensure that the R WS limits prescribed in the permits are not exceeded. During initial pumping operations, a series of small controls adjustments within the limits of the design specification were made with satisfactory results in order to maintain permit compliance and validate the operating procedures while running in automatic mode.

During the first quarter, the RWS operated satisfactorily and as designed, with occasional minor short-term weather-related (lightning-based power fluctuations) deviations. Figure 3.4-1 shows the operation of each recovery well for the first quarter of operation. Collectively, the recovery well pumps ran approximately 96% of the time. Table 3.4-1 shows the provisional daily volume ofhypersaline water pumped from each recovery well and the amount disposed in the DIW.

From May 15, 2018, through August 15, 2018, almost 1.4 billion gallons ofhypersaline water was extracted and disposed of via the DIW.

Table 3.4-2 shows the amount of salt mass removed on a weekly basis for each recovery well, which is calculated in accordance with the FDEP Consent Order, paragraph 29.f. Since August 15, 2018, was during the middle of the week, the weekly salt mass removal data extend to August 19, 2018. The salt mass values were based on automated flow and TDS data and then summed for daily and weekly salt mass removal. The TDS value is calculated from specific conductance using a conversion factor of 0.64. The equation for salt mass removal is as follows:

Salt mass removed= ((1,000

3.7854 * [FLOW] * [TDS]) / 453,592.37).

Flow is reported in gpm, while TDS is reported in parts per thousand (ppt). Salt mass removal is reported in pounds per day. The total amount of salt mass removed during the period from May 15, 2018, through August 19, 2018, was 577.5 million pounds.

3.5 Drawdown and Capture Zone of RWS The May 15, 2018, MDC letter requested FPL to provide a groundwater elevation map and drawdown contour map depicting the cone of influence of each extraction well and a demonstration of the RWS capture radius. To facilitate the development of a groundwater elevation map for the area, automated data from a common date and time were used, as shown in Table 3 .5-1. The resulting groundwater contour map, which is based on water levels collected from the shallow monitoring horizon at 8:00 pm on May 18, 2018, is provided as Figure 3.5-2.

Turkey Point Units 3 and 4 L-2019-031 Enclosure 1 Docket Nos. 50-250 and 50-251 Recovery Well System Startup Report Page 25 of65 FPL Turkey Point Recovery Well System Startup Report October 2018 3. Recovery Well System Baseline Data and First Quarter of Operation There is a regional easterly groundwater gradient, which is very low and indicates that very low eastward flow velocities occurred in the shallow portion of the Biscayne aquifer at the time these data were collected.

The production of a drawdown contour map depicting the cone of influence of each extraction well and the capture radius of the RWS is a more complex task. Under field conditions, drawdowns can be estimated by comparing measured groundwater elevations prior to, during, and after pump withdrawals are initiated. Based on the aquifer characteristics and pumping rates, the number and location of monitoring wells necessary to identify field scale drawdowns can be determined. However, considering the extent and number ofRWS production wells, the placement of multiple monitoring wells next to each of the 10 RWS extraction wells was not economically feasible. As an alternative, FPL developed estimates of drawdown and the area of influence/capture zone by considering: (1) automated groundwater elevation data collected from the existing RWS monitoring wells at hourly intervals prior, during, and after the RWS startup; (2) data from the aquifer performance test conducted pursuant to paragraph 17.b.i. of the MDC Consent Agreement; and (3) modeling results from the RWS design and permitting.

Figure 3.5-1 shows hourly groundwater levels from shallow monitoring wells 5 days prior to the May 15, 2018, RWS startup and 10 days following the start. The RWS pumps were turned on around 8:00 a.m., turned off around 10:00 p.m., and then turned back on around 2:00 p.m. for

continuous operation. The graph shows that there were no clear responses to pumpage in groundwater levels at the monitoring wells. Rather than a decrease, there was an increase in groundwater levels around the time ofRWS startup due to multiple rain events, with the largest increase occurring on May 20, 2018. Through the first quarter, trend lines for all of the wells (TPGW-1, TPGW-2, TPGW-4, TPGW-5, TPGW-7, TPGW-12, TPGW-17, TPGW-18, and TPGW-19) were nearly level (slopes 0.007% to 0.39%), which suggests drawdown influences from the RWS operation in the shallow portion of the aquifer are very small and masked by the rainfall.

FPL conducted an aquifer performance test (APT) in 2016 (as required in paragraph 17.b.i. of the MDC Consent Agreement; April 1, 2016, report submitted to MDC) on a test well that later became RWS-3. Under the APT, the test well was pumped at a steady rate of 6.57 mgd, with water level data collected from monitoring wells at 40, 90, and 720 ft from the test well.

Drawdowns during the tests in the shallow monitoring wells ranged between 0.1 to 0.2 ft. It is likely that the drawdowns would be less than this, with the RWS well pumping at a rate of 1.5 mgd.

The Agency approved groundwater 3D variable density solute transport model that was used to design the RWS was also used to assess potential drawdown in the uppermost portion of the aquifer for the SFWMD consumptive use permit review. The use of the model has advantages, as it can eliminate external confounding factors such as a rainfall events and can simulate performance under drought conditions (1 in 10 drought conditions were simulated for determining drawdown and cone of influence/capture zone for the RWS consumptive use permit). Figure 3.5-3 shows the modeled drawdown and area of influence/capture zone for layer 1 of the model during 1 in 10 drought conditions. The model indicates drawdowns similar to 3-5

Recovery Well System Baseline Data and First Quarter of Operation those produced in the APT with drawdowns less than 0.3 ft at the wellsite. FPL considers the model generated 1 in 10 year drought the best available representation of the R WS draw down, cone of influence and capture zone.

Based on evaluation of field data collected during the R WS startup, APT results, and modeling, it is estimated that the drawdown associated with the operation of the RWS wells on shallow groundwater is de minimis and not sufficient to impact area wetland hydrology.

3.6 Impacts of RWS and Combined Influence of ID Operations of the interceptor ditch (ID) pumps are based on agencies' approved protocols contained in the Interceptor Ditch Operational Plan. Since the RWS began operation, water levels in the L-3 lE canal, the ID, and the CCS have not triggered operations of the ID pumps.

Accordingly, there have been no instances where the cumulative impacts of the RWS operations and ID pumps can be measured.

Evaluation ofRWS impacts to groundwater levels in the area document that the RWS is not adversely impacting the groundwater, wetlands, or other water resources. As discussed in Section 3.3, water quality in these wells remain similar to those reported prior to startup of the RWS. Over time, it is expected that groundwater quality will improve as the mass of hypersaline groundwater is reduced by the RWS. As a result, no changes or optimizations have been made to the R WS since the system was put into service on May 15, 2018, nor are any changes proposed at this time.
