| ==SUMMARY==
| |
| | |
| An Extended Power Uprate (EPU) was undertaken to increase the generating capacity and improve operating efficiency of both units at Florida Power & Light Company's (FPL's) St.
| |
| Lucie Plant on Hutchinson Island, St. Lucie County, Florida. The EPU is expected to result in a slight increase (2.0°F) in the temperature of cooling water discharges into the Atlantic Ocean. A Biological Plan of Study (POS) was developed to assess the extent, if any, to which these elevated temperatures may affect the protection and propagation of a balanced, indigenous population of shellfish, fish and wildlife in the receiving water body. The Biological POS was approved by the Florida Department of Environmental Protection (FDEP) on August 18, 2011, and study implementation began soon thereafter. This report summarizes results of eight baseline monitoring events and six post uprate monitoring events conducted through January 2014.
| |
| Sampling consisted of water quality monitoring, collection of fish and shellfish by trawl, gill net, and beach seine, and monitoring of sea turtle utilization of nearshore hardbottom. Monitoring was performed approximately every other month between August 2011 and January 2014. Three discrete areas, one centered around the plant within the zone of thermal influence (Area SL2) and two reference sites located north (Area SLI) and south (Area SL3) of the plant, were used to establish baseline conditions.
| |
| Though there were a number of differences among areas with respect to monitored water quality variables, only rarely did Area SL2 differ significantly from both reference sites. There were no persistent trends indicating major differences in bottom or surface water column dissolved oxygen, pH, salinity, specific conductivity, or temperature among areas prior to or after the uprate.
| |
| Results of trawl sampling indicate a diverse invertebrate and fish fauna in all three areas with considerable spatial and temporal variability in faunal densities. Clupeiform fish (anchovies, herrings, and sardines), a Representative Important Species (RIS), accounted for over 40 percent of the total catch. The species comprising this group provide forage food for a large variety of predatory fish, many of which are commercially and recreationally important. Twelve Commercially/Recreationally Important (CRI) decapod crustaceans were collected in trawls during baseline sampling. There were no statistically significant differences in the mean number fish, RIS, or CRI decapod crustacean taxa among areas before or after the uprate. Furthermore, there were no statistically significant differences among areas pre- or post-uprate with respect to the mean Catch per Unit Effort (CPUE) for these groups or for individual RIS taxa. Finally, no statistically significant differences were detected between Area SL2 and the other two areas in the mean biomass of RIS captured before or after the uprate.

| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Gill-net sampling targeted fish including RIS. Atlantic bumper, Atlantic sharpnose shark, and bonnethead shark collectively accounted for over half of all captures. The most abundant RIS included Atlantic croaker and Atlantic Spanish mackerel. As with trawl sampling, there was considerable variability in the number of taxa and CPUE per sampling event. There were no statistically significant differences in the number of fish taxa among areas prior to the uprate.
| |
| After the uprate, statistical analysis indicated that the number of fish taxa in Area SL2 was significantly less than the number in SLI, but not significantly different from the number in Area SL3. There were no statistically significant differences in the number of RIS fish taxa among areas during either pre- or post-uprate sampling periods. For fish and RIS CPUE, there were no statistically significant differences among areas prior to or after the uprate. With regard to mean CPUE of individual taxa of RIS, only one of eleven taxa exhibited any statistically significant differences among areas. During post-uprate monitoring, the mean CPUE of clupeiformes was statistically significantly higher in the north reference site than the south reference site, however, the mean CPUE at the power plant site was not statistically significantly different from means in either other area. There were no statistically significant differences in mean RIS biomass among areas either before or after the uprate.
| |
| Beach-seine sampling provided information on fish (including RIS) inhabiting the surf zone.
| |
| Again, there was considerable variability among sampling events with respect to the number of taxa and, in particular, the number of individuals captured by seine. This was mainly due to a large catch of scaled sardines in Area SL3 during one sampling event. Aside from the large catch of scaled sardines, which accounted for 74 percent of all specimens collected, sand drum, Atlantic bumper, and Spanish sardine accounted for the largest number of individuals captured by seine. There were no statistically significant differences in numbers of fish or RIS taxa collected by beach seine among areas before or after the uprate. There were no statistically significant differences in the mean numbers of RIS among areas during pre- or post-uprate events when scaled sardines were included. When scaled sardines were excluded, there were no significant differences among areas during pre-uprate events, but during post-uprate events Area SL3 had a statistically significantly higher mean number of RIS fish than the Areas SLI and SL2. However, the post-uprate means for Areas SLI and SL2 were not statistically significantly different. When numbers of individual taxa of RIS were compared among areas, no statistically significant differences were found among areas during either pre- or post-uprate events. There were no statistically significant differences in RIS biomass among areas during either pre- or post-uprate events, with or without the inclusion of scaled sardines.
| |
| Numerous taxa of fish and CR1 crustacean larvae and large quantities of fish eggs were collected during plankton sampling. Clupeiformes dominated the larval fish, accounting for 47 percent of all individuals captured. As with other biological sampling, there was considerable variability among sampling events. However, differences in the mean number of fish larvae taxa, fish egg taxa, CRI crustacean taxa, fish larvae CPUE, fish egg CPUE, and CRI crustacean larvae CPUE ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 221
| |
| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY from plankton samples were not statistically significant among areas either before or after the uprate.
| |
| The mean number of green turtle sightings in Area SL2 was statistically significantly greater than the means in the other two areas during pre-uprate events, but not significantly different from those areas during post-uprate events. This change in the relationship among areas appeared to be due to slight increases in the reference sites and a small decrease at the discharge site between pre- and post-uprate events. None of these changes in mean numbers of green turtle sightings between pre- and post-uprate events within areas were statistically significant.
| |
| Whether the change in the relationship among areas reflects an uprate effect or simply natural variability in the distribution of green turtles should be revealed by subsequent monitoring.
| |
| Collectively, data collected to date indicate a diverse fish and shellfish community in nearshore waters of the Atlantic Ocean offshore the St. Lucie Plant. These faunal communities exhibit considerable spatial and temporal variability. Typically, faunal conditions in Area SL2 (discharge site) were not statistically significantly different from conditions found in the two reference sites during pre- or post-uprate monitoring. Additional post-uprate monitoring will allow for better comparisons of faunal conditions before and after the uprate.

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY INTRODUCTION Florida Power & Light Company (FPL) applied to the Florida Department of Environmental Protection (FDEP) for a revision to its National Pollution Discharge Elimination System (NPDES) Permit (FL0002208), which authorizes thermal discharges into the Atlantic Ocean from the St. Lucie Nuclear Plant on Hutchinson Island, St. Lucie County, Florida. The revision, which became effective on December 23, 2010, allows for a minor increase in effluent temperatures, approximately 2.0°F (1.1°C) under normal operating conditions, resulting firom an extended power uprate (EPU) for both Units I and 2 at the plant.
| |
| Administrative Order (AO) AO022TL authorizes the above-referenced St. Lucie Plant EPU with conditions. Paragraph 20 of the AO stipulates that no later than 90 days after the effective date of the AO, FPL shall prepare and submit for the Department's review and approval a Biological Plan of Study (POS). The AO further identifies specific elements to be incorporated into the design of the POS. These elements were derived from historical Environmental Protection Agency (EPA) guidance addressing the regulation of thermal effects associated with nuclear plants.
| |
| A draft Biological POS was prepared in early 2011 and discussions with FDEP ensued.
| |
| Following receipt of review comments in May 2011, a final Plan was submitted to the Department on June 1,2011 and approval was granted on August 18, 2011.
| |
| The Biological POS for the St. Lucie Plant EPU is intended to characterize the fish and shellfish fauna in the vicinity of the plant, and assess the extent, if any, to which the EPU has affected those communities. Based on the nature of the receiving water body (Atlantic Ocean - open waters), the small change in discharge temperature resulting from the EPU, the effectiveness of the offshore discharge pipes in diffusing heated cooling water, and the limited spatial area historically affected by discharges, effects of the EPU are anticipated to be limited. Results of the Biological POS coupled with extensive prior 316(a) studies at the St. Lucie Plant will enable FPL to effectively demonstrate whether or not the St. Lucie Plant EPU is jeopardizing the protection and propagation of a balanced, indigenous population of shellfish, fish and wildlife in the receiving water body.
| |
| As described below, the Biological POS consists of trawling, gill netting, beach seining, plankton netting, and monitoring of sea turtle utilization of nearshore hardbottom. Sampling techniques largely replicate those used in prior 316(a) demonstration studies at the St. Lucie Plant to provide comparable contemporary data. The POS called for baseline monitoring prior to completion of the St. Lucie Plant EPU, and two years of post-EPU monitoring. Baseline ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA
| |
| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY sampling was conducted from August 2011 through October 2012, and the first year of post-uprate sampling from January 2013 through January 2014. The results of individual sampling events were previously reported to FPL. This report summarizes those results and compares pre-and post-uprate data between seasons and among study areas.
| |
| METHODS Sampling Period Baseline monitoring commenced in August 2011 following FDEP approval of the Biological POS and continued through October 2012. The EPU was completed in December 2012 and the first post-uprate sampling event was conducted in January 2013. Sampling was performed every other month for a total of eight baseline sampling events and six post-uprate events included in this report. For purposes of this report, the summer season encompasses sampling events conducted from May through October, and winter season from November through April.
| |
| General Sampling Areas Three separate sampling sites were established within the study area, each measuring approximately 2.0 mi (3.2 kin) on a side (Figure 1). Within the near and far field area surrounding St. Lucie Plant's discharge structures, the first site (SL2) extends from shore along the axis of the Unit 2 multi-port diffuser. The north and south boundaries of the discharge site are located 1 mi (1.6 kin) from the discharge structure and parallel the center line. Within this bounded area, three unique habitat types are present, each with a unique benthic and fish fauna:
| |
| the beach terrace (shallow sandy areas near shore in depths less than about 20 ft (6.1 m), an offshore trough (a relatively homogenous shell hash substrate in 35-40 ft (11-12 m), and an offshore shoal (sandy substrate that rises to a depth of approximately 20 ft (6.1 m; EAI, 2001).
| |
| Two additional sites of equivalent size to the discharge site and positioned similarly served as reference sites to document background conditions in areas unaffected by thermal discharges.
| |
| One of these was located approximately midway between the discharge site and the Ft. Pierce Inlet (SLI) and the other midway between the discharge site and the St. Lucie Inlet (SL3; Figure 1).
| |
| Precise sampling locations within each area were established during the initial baseline sampling event. A Global Positioning System (GPS) was used to capture sampling points and transect end points, as applicable. Following the initial sampling event, all sampling locations remained fixed for the duration of the study period.

| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Specific Sampling Locations Within each of the three areas, three transects progressively distant from shore were established for gill net and trawl sampling. The transects are located approximately 600 ft (183 m) from shore on the beach terrace in water depths of 8-32 ft (2.4-9.8 m; Transect A), approximately 4,000 ft. (1.2 kin) from shore in water depths of 34-45 ft (10.4-13.7 m; Transect B), and approximately 8,000 ft. (2.4 kin) from shore in water depths of 31-47 ft (9.4-14.3 m: Transect C).
| |
| A schematic of transect locations within the discharge area is shown in Figure 2. Plankton samples were collected concurrently with trawl samples in all three areas but only on Transects A and C.
| |
| Beach seining was conducted at three stations within each of the three sampling areas. Station A is located approximately 0.5 mi. (0.8 kin) north of the center of each area, Station B is located at the center of the area, and Station C is located approximately 0.5 mi. south of the center of the area (Figure 2). Final station locations were adjusted, as necessary, to avoid potential bottom obstructions.
| |
| For the purpose of boat-based sea turtle surveys, a 0.6 mi- (1 kin-) long transect was established in the vicinity of nearshore hardbottom in each of the three sampling areas. The approximate location of these transects was based on recent aerial photography and then adjusted in the field using towed underwater video cameras.
| |
| Water Quality Water quality data were recorded at three locations (middle and both end points) and three depths (approximately 30 cm below the.surface, mid-depth and 30 cm above the bottom) along each of the nine transects established for trawl and gill net sampling. A Hach Quanta water quality meter was used to document water quality at each sampling point. Monitored variables included: specific conductivity (mS/cm), temperature (°C), salinity as a function of conductance (practical salinity units [PSU]), dissolved oxygen (mg/L), and pH. The meter was calibrated prior to the start of daily sampling activities and again at the completion of sampling.
| |
| Trawling Trawling was conducted along each of the three shore-parallel transects established within each area, yielding a total of 72 baseline and 54 post uprate samples. Trawl sampling utilized a 16-ft (4.9-m) by 3-ft (0.9 in) semi-balloon bottom trawl, having a 0.5-in (12.7 mm) stretch mesh in the bag and 0.25-in (6.4-num) stretch mesh in the cod end. The net was towed on the bottom at speeds of 2-3 knots for 15 minutes along each transect. The tows typically intersected the ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 3
| |
| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY approximate midpoint of each of the three gill net transects (Figure 2). Sampling at all sites was performed at night.
| |
| All fish captured by trawl were identified to species and counted. Additionally, a maximum of 25 representative specimens of each Representative Important Species (RIS; see below) captured were measured (standard length and total length) and a batch weight for those specimens obtained. Trawl data are presented as total number of individuals captured, number of individuals captured per kilometer of bottom trawled (Catch per Unit Effort; CPUE), and average length and weight of RIS. CPUE is used to account for differences in tow distances resulting from varying boat speeds and currents. Biomass for RIS was determined by dividing the batch weight of each taxon by the number of specimens weighed and then multiplying the average weight by the total number of specimens in the sample.
| |
| All invertebrates captured by trawl were counted and identified to major taxonomic group (e.g.,
| |
| spider crab, swimming crab, squid, etc.). Additionally, any Commercially/Recreationally Important Species (CRI; e.g., blue crabs, penaeid shrimp, lobster, etc.) in the catch were identified to the lowest practicable taxon.
| |
| Gill Netting Gill net sampling was conducted along three shore-perpendicular transects established within each area, yielding a total of 72 baseline and 54 post uprate samples. Within the discharge study site, the transects were sited either north or south of the multi-port diffuser, depending on predominant current flow at the time of sampling, to ensure the net fished within the thermal plume, if present (Figure 2). The gill net was 600 ft (183 in) in length and 12 ft (3.7 m) in depth, and consisted of 5 monofilament mesh panels, each 120 ft (66.6 m) long. Mesh sizes (stretch length) of the five panels are as follows: 2.5 in (64 mm), 2.9 in (74 mm), 3.3 in (84 mm), 3.8 in (97 mm), and 4.6 in (117 mm). The variable mesh allows the capture of numerous fish species of different size classes. The bottom line of the gill net was weighted such that it rested on the bottom, and floats on the top line kept the net suspended in the water column. Sampling at all sites was conducted during daylight hours.
| |
| Gill nets remained in the water a minimum of 30 minutes, with total soak time calculated from the time the lead end of the net went into the water until the time the terminal end was back onboard the vessel. All fish captured by gill net were identified to species and counted.
| |
| Additionally, a maximum of 25 representative specimens of each RIS captured were measured (total length) and a batch weight for those specimens obtained. Gill net data is presented as described above for trawling with the exception that CPUE represents the number of individuals captured per hour of soak time. Soak times often varied considerably in relation to sea conditions and/or the number of fish being captured.

| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Beach Seining Beach seining was conducted at three locations within each of the three study areas, yielding a total of 72 baseline and 54 post uprate samples. The seine consisted of a 100-ft (30.5-m) long by 6.0 ft (1.8-m) deep net having a stretch mesh of 1 inch (25 mm). The net is heavily weighted along the bottom and has extra floatation on the top so it maintains a vertical hanging position in the water column under surf conditions. The rolled net was carried out to a depth of approximately 4 ft (1.2 in), deployed parallel to shore and then pulled onto the beach with the ends perpendicular to shore. This created a U-shaped barrier, with fish funneled to the central part of the net as it was brought on shore. Sampling was performed during daylight hours.
| |
| Fish and invertebrates captured by seine were processed, as described above for gill netting and trawling. Data are presented as total number of individuals captured, with average length and weight also reported for RIS. Insofar as the exact area of bottom sampled by the seine could not be accurately determined, no CPUE data are presented.
| |
| Plankton Netting Nighttime sub-surface plankton tows were made concurrently with trawling along Transects A and C within each study area (Figure 2), yielding a total of 48 baseline and 36 post uprate samples. Sampling was conducted using paired bongo nets (20-cm diameter) having a 500 micron mesh. Each net was equipped with flow meters to allow determination of volume of water filtered. The nets were towed for 15 minutes, unless clogging required shorter tow times.
| |
| Once the nets were retrieved aboard the vessel, the contents from both cod ends were combined into a single sample and preserved in 10% buffered formalin for laboratory identification. In addition to quantifying ichthyoplankton in the bongo net collections, any captured CRI decapod crustacean larvae were identified and enumerated. CRI target species included, but were not limited to, penaeid shrimp, blue crabs, stone crabs, lobster, and mole crabs. Plankton data are presented as total number of individuals captured and number of individuals captured per 100 cubic meter of water filtered (CPUE).
| |
| NearshoreHardbottoni Utilization by Sea Turtles A single l-kin shore-parallel transect was monitored in each of the three study areas. Each transect was traversed two times during each sampling event with at least a 30 minute separation between the two passes. A total of 48 baseline event observations and 36 post-uprate observations were made. Sea turtle surveys were performed from a boat equipped with an elevated platform capable of holding two observers. As the boat traversed each transect at a slow and constant speed (4.0 knots or less), one observer would look to port side and the other to starboard side. Observers would record and identify to species, when possible, any turtle ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 5

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY observed surfacing within approximately 100 ft (30 m) of the transect centerline. Monitoring days were selected for optimal viewing capabilities (e.g., sunny with calm seas).
| |
| RepresentativeImportantSpecies Section 4.0 of the Interagency 316(a) Guidance Manual (EPA, 1977) defines Representative Important Species as having one or more of the following traits: commercially or recreationally valuable; threatened or endangered; critical to the structure and function of the ecosystem; and/or a necessary component of the food chain for the preceding species. RIS for the Biological POS were selected based on results of prior 316(a) demonstration studies at the St. Lucie Plant and included 11 taxa of fish and one species of sea turtle, as follows:
| |
| : 1. Atlantic croaker (Micropogonias undulatus) - This bottom associated species, which is part of the recreational fishery, was one of the most abundant species captured in both gill nets and trawls during prior studies at the plant. It spawns offshore and gravid females have been found throughout the year.
| |
| : 2. Spot (Leiostomus xanthurus) - This bottom associated species is a common species along the Atlantic coast and was one of the most abundant species captured in both gill nets and trawls during prior studies at the plant. Spawning occurs offshore during the late fall, winter, and early spring and peaks in December and January.
| |
| : 3. Sand Drum (Umbrina coroides) - This bottom associated species is a common species along the Atlantic coast and was one of the most abundant species captured in both gill nets and trawls during prior studies at the plant. Spawning occurs offshore during the late fall, winter, and early spring and peaks in December and January.
| |
| : 4. Pigfish (Orthopristis chiysoptera) - This bottom associated species is a common recreational species along the Atlantic coast and accounted for a large percentage of biomass for all species captured by trawl during prior studies at the plant. Spawning occurs offshore during the fall, winter, and spring.
| |
| : 5. Bluefish (Pomatomius saltatrix) - This conmm-ercially and recreationally important schooling predator regularly occurs in coastal waters of east Florida, although it is present in greatest numbers during the fall and winter. It was captured in large numbers by gill net during prior studies at the plant. Gravid females were present throughout the year, although spawning within the south Atlantic fisheries stock occurs primarily in early summer along the continental shelf between northern Florida and Cape Hatteras.
| |
| : 6. Silver Seatrout (Cynoscion nothus) - This important recreational species, occurs in the vicinity of the plant and was relatively common in gill net and trawl collections during ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 6
| |
| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY prior studies at the plant. Seatrout are bottom associated species that spawn offshore, and gravid females have been found throughout the year.
| |
| : 7. Kingfish/Whiting (Menticirrhus spp.) - Both the Gulf (M littoralis) and southern (M americanus) kingfish occur in coastal waters over sandy bottom and were routinely captured in ocean beach seines during previous studies at the plant. Both species are taken in the recreational fishery. They typically spawn in the ocean during spring, summer and fall.
| |
| : 8. Florida pompano (Thachinotus carolinus)- This species is a commercially important and recreationally popular coastal species often found in small to large schools along sandy beaches. Florida pompano were often captured in beach seines during previous studies at the plant. This species primarily spawns in the spring and summer.
| |
| : 9. Spanish mackerel (Scomberomorus inaculatus)- This schooling coastal species is both commercially and recreationally important in eastern Florida waters and was one of the most frequently caught species in gill netting operations conducted during previous studies at the plant. Although it occurs throughout much of the year, largest concentrations occur during the fall and winter, with gravid females being present primarily during the spring, summer, and fall. Spanish mackerel feed on a variety of Clupeiform fish (herrings and sardines) which are extremely abundant in the nearshore waters off Hutchinson Island.
| |
| : 10. Clupeiformes - This group includes a variety of anchovies, herrings and sardines, the primary source of food for most of the commercially important piscivorous fish species that migrate through the area. Clupeiformes were numerically prevalent in both trawl and gill net sampling previously conducted at the plant.
| |
| : 11. Leopard Searobin (Prionotus scitulus) - The leopard searobin is a benthic oriented fish that is common over sandy substrates. It was one of the most frequently captured species in trawl sampling during previous studies at the plant. Individuals in spawning condition were captured in winter and spring.
| |
| : 12. Green sea turtle (Chelonia mnydas) - The green sea turtle is federally listed as endangered.
| |
| Juveniles are found in inland estuaries where they occupy and feed on submerged aquatic vegetation. They are also regularly found in the ocean where they feed on algae that colonize exposed hardbottom and worm reef. Large numbers of juvenile green turtles occur in the ocean in the vicinity of the St. Lucie Plant, as evidenced by their routine entrapment in the plant's cooling water intake system.

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY StatisticalAnalysis All variables were statistically analyzed using STATISTICA 64, Version 11 software (Statsoft, Inc.). Data were first tested to determine if they met requisite requirements for parametric testing, including normality (Shapiro-Wilks Test) and homogeneity of variance (Levene's Test).
| |
| These tests revealed that the water quality data met both assumptions; however, the faunal data did not. Based on these results, non-parametric tests were used for all analyses of faunal data.
| |
| To detect the potential impact of the St. Lucie EPU during faunal sampling events, water quality variables were analyzed using Repeated Measures Analysis of Variance (ANOVA) to determine if statistically significant differences (p<0.05) existed among sampling events. If significant differences were detected, the Tukey Honest Significant Difference (HSD) Test was used to determine which mean values were significantly different.
| |
| Separate analyses ,Vere done for each type of faunal sampling: trawls, gill nets, beach seines, plankton tows, and sea turtle surveys. Data were analyzed separately for: all fish, RIS, fish larvae, fish eggs, CRI decapod crustaceans and CR1 decapod crustacean larvae. Each group was analyzed for differences in the number of taxa collected, total number of individuals captured, and/or CPUE. Biomass was also analyzed for RIS fish. All data were analyzed using a Kruskal-Wallis Analysis of Variance by Ranks Test (ANOVA) to determine if statistically significant differences (p<0.05) existed among transects, areas, season, and pre- and post-uprate events. If significant differences were detected, the Multiple Comparisons of Mean Ranks Post-hoc Test was used to determine which values were significantly different within the ANOVA. In certain instances, the ANOVA and the Multiple Comparisons Tests reported conflicting results. In these cases, Mann-Whitney U Tests were performed among areas (including the following comparisons SLI vs SL2, SL2 vs SL3 and SLI vs SL3) to determine which were significantly different from each other.
| |
| Differences among transects may be indicative of nearshore to offshore gradients, while differences among study areas may be indicative of shore-parallel gradients. Seasonal changes and/or long-term temporal patterns are assessed by analyzing for differences among sampling events. For the purpose or these analyses the sampling events were grouped into either summer or winter seasons. The summer season included events from May through October while winter events were from November through April.
| |
| During the study period, an abnormally large number of individuals of a single taxon were captured during a few sampling events at one or more stations. For these events, the data was analyzed with and without the large catch to improve the resolution of the statistical tests. Due to the high variability of faunal data, additional statistical tests were performed in a nested design that reduced variability in the data to enhance the detection of significant differences among ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 8
| |
| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY areas. For example, the test comparing areas among all sampling events can be improved by removing the seasonal and nearshore/offshore variability by structuring the test to only analyze the data among areas, within a transect, within a season, within pre- or post-uprate event period.
| |
| Despite the attempts to improve the resolution of the statistical test, no additional significant differences were found among study areas and hence the data is not presented in this report.
| |
| RESULTS Water Quality Differences in time of day, tidal stage, and weather conditions both between and during each sampling event create considerable spatial and temporal variability in water quality parameters.
| |
| Nevertheless, general characterizations can be made about similarities and differences in measured variables among study areas comparing summer and winter pre- and post-uprate values.

| pH Gill Netting - During daytime sampling, mean bottom pH ranged from 7.87 to 8.25, with a mean value of 8.04 for all areas and seasons combined (Table 5). There were no statistically significant differences among areas during pre-uprate events (Figure 8). During post-uprate events, the mean in SL2 was statistically significantly lower than in SLI but not statistically significantly different than in SL3. Within areas, means in SLI and SL3 exhibited a statistically significant increase between pre- and post-uprate events, but there was no statistically significant difference between pre- and post-uprate means in SL2. Mean surface pH ranged from 7.87 to 8.22 and averaged 8.02 for all areas and seasons combined (Table 6). As with bottom pH, there were no statistically significant differences in mean surface pH values among areas during pre-uprate events and during post-uprate events the mean in SL2 was statistically significantly lower than the mean in SLI but not statistically significantly different than the mean in SL3 (Figure 7).

| Results of comparisons of mean surface pH values between pre- and post-uprate events within each area also followed the same pattern as with mean bottom pH. There were statistically significant increases in means in SLI and SL3 between pre- and post-uprate events, but no statistically significant change in mean surface pH in SL2. The relationship of the three areas with respect to mean surface and bottom pH during each sampling event are shown in Appendix Figures 5 and 6. There were no consistent differences before or after the uprate.

| Trawling Table 21 provides the common and scientific names of all organisms captured for all sampling types combined during eight pre-uprate and six post-uprate biological sampling events. One hundred fifty three (153) taxa, representing 79 fish, 62 crustaceans, and 12 miscellaneous taxa, were captured by trawl (Table 22). A total of 4,854 organisms were identified and enumerated from the collection (1,655 fish, 2,561 crustaceans, and 638 other organisms, primarily echinoderms). Nine (9) of the 11 RIS were represented in the catch, and collectively they accounted for 63% of all fish specimens collected during baseline trawling. Clupeiformes (anchovies, herrings, and sardines), represented primarily by unidentified Engraulids and the Cuban anchovy (Anchoa cubana), accounted for over 40% of the total fish caught. The species comprising this group provide forage food for a large variety of predatory fish, many of which are commercially and recreationally important. The star drum (Stellifer lanceolatus), Atlantic bumper (Chloroscombrus chrysurus), tomtate (Haemuion aurolineatum), and sand drum (Umnbrina coroides) were also caught in relatively high numbers. Collectively, these six taxa accounted for approximately 70% of the total catch. There were no statistically significant differences among areas with respect to number of fish taxa, RIS taxa, or CRI invertebrate taxa prior to or after the uprate (Table 23). However, the number of fish taxa was statistically significantly lower during post-uprate monitoring in comparison with pre-uprate monitoring at Areas SL2 and SL3 (Table 24). The number of RIS taxa was also significantly lower during post-uprate trawling at Area SL3.
| |
| Of the fish taxa, Engraulidae and Anchoa cubana had the greatest CPUE (2.85/km and 2.84/km respectively), while over 75% of the other fish captured had a CPUE of 0.10 or less (Table 25).
| |
| The mean CPUE for all fish taxa combined ranged from 1.53/km in Area SL2 for post-uprate summer events to 74.43/km in Area SLI for pre-uprate summer events (Table 26). The much higher mean CPUE for all areas in the pre-uprate summer season is due to single event catches of relatively high numbers of clupeiforme fishes. Comparing the winter season pre- and post-uprate mean CPUE by area shows smaller differences. When the mean CPUE values for all fish taxa were compared among areas, no significant differences were found (Table 23). Large catches of anchovies, Engraulidae, were responsible for a substantial amount of variation in the data, therefore, it was removed from analysis to improve the resolution of statistical tests. Even after excluding anchovies, no significant differences were found among areas before or after the uprate (Table 23). Though there was a statistically significant decrease in fish CPUE and fish CPUE excluding Engraulidae after the uprate in SL2, this also occurred in SL3 (Table 24).

| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Insofar as Clupeiformes (an RIS) accounted for a large percentage of the total fish catch, seasonal patterns for RIS CPUE were similar to those for all fish species when RIS were analyzed separately (Table 27).
| |
| The anchovies, herrings and sardines comprising the Clupeiformes occur in large schools that are common throughout the study area. However, their chance occurrence at the time and location of sampling can skew catch numbers. For example, Clupeiform fish accounted for 82% of all RIS captured during baseline monitoring, and all but one of those was captured during a single sampling event (October 2012; Table 28). Seventy-three (73) percent and 25 percent, respectively, of all Clupeiformes were caught in Areas SLI and SL2, with only 2 percent caught in Area SL3 for all analyzed sampling events. Thus, it is not surprising that Area SLI had the greatest number of all RIS specimens captured (725), and SL3 had the fewest (105). The mean CPUE for each RIS species were compared among areas before and after the uprate, however, no statistically significant differences were found (Table 29). However, comparisons within each area revealed that Prionotus scitulus was significantly more abundant during the pre-uprate period than the post-uprate period in Areas SL2 and SL3 (Table 30).
| |
| When captures were adjusted to account for variable tow distances, CPUE for RIS ranged from 54.24/km in Area SLI for summer pre-uprate events to 0.87/km in Area SL3 for winter pre-uprate events (Table 31). Prior to the uprate regardless of season, mean RIS CPUE at SL2 was intermediate between means at SLI and SL3. Comparing post-uprate summer events, means decreased in all areas with the lowest mean occurring in SL2. For winter events, means increased slightly after the uprate and there was little difference among areas. There were no statistically significant differences in mean RIS CPUE among areas before or after the uprate regardless of whether Engraulidae was included or excluded (Table 23). Within areas, no statistically significant differences were found when RIS CPUE was compared between pre- and post-uprate periods (Tables 24).
| |
| The mean total length (TL) for each taxon of RIS collected by trawl during pre- and post-uprate sampling is presented in Table 32. The species with the largest mean TL included Atlantic croaker (Micropogonias undulates; 237.36 mm), pigfish (Orthopristischrysoptera; 230.0 mam),
| |
| and silver seatrout (Cynoscion nothus; 225.44 mm).
| |
| Despite representing the greatest number of specimens captured by trawl during baseline sampling, Clupeiformes represented only 18% of the RIS biomass. Mean weights and total biomass for RIS collected within each area during baseline trawl sampling, all events combined, are presented in Tables 33 and 34, respectively. For many of the RIS there is not paired data for pre- and post- or summer and winter events for the areas. For example, during the summer pre-and post- events in SL1, nine of the 12 taxa were only captured in either pre- or post-uprate events but not both. Similarly eight of the nine RIS collected during winter sampling in SLI ECOLOGICAL AssocIATES, INC., JENSEN BEACH, FLORIDA 14
| |
| | |
| PRELIMINARY FINDINGS, ST. LucIE PLANT EPU BIOLOGICAL PLAN OF STUDY were only represented in pre- or post-uprate events but not both. The mean weight was lower in all areas during post-uprate versus pre-uprate sampling for both summer and winter. Total biomass is tied to number of fish collected and mean biomass. Since there were eight pre-uprate sampling events and six post-uprate events, the total biomass will be biased for pre-uprate sampling. Mean biomass removes the bias for the difference in number of sampling events. Area SL2 had a lower mean biomass than SLI or SL3 during summer pre-uprate sampling but was higher than SLI during winter sampling. During post-uprate sampling, SL2 was again lower than both reference sites during the summer but higher than SL3 in the winter. When Engraulidae was included, there were no statistically significant differences in mean RIS fish biomass among areas prior to the uprate (Table 23). After the uprate, statistical tests indicated that mean RIS fish biomass was significantly higher in SLI than SL3, but SL2 was not significantly different from either reference site. When Engaulidae was excluded, there were no statistically significant differences among areas before or after the uprate. Within SLI, the difference in mean RIS Fish biomass between pre- and post-uprate periods was not statistically significant (Table 24). However, statistical analysis indicated that the pre-uprate means in SL2 and SL3 were significantly greater than the post-uprate means (Table 24). The results of the statistical tests were the same whether or not Engaulidae was included.
| |
| A total of 3,199 invertebrates represented by 74 taxa were collected by trawl during pre- and post-uprate sampling (Table 22). The largest total number of invertebrates were captured in Area SL2 (1770) and the fewest in Area SL3 (444; Table 35). Mean CPUE for all invertebrates combined ranged from 11.92/km in Area SL3 to 45.55/km in Area SL2. Means in all areas were higher during the pre-uprate period than during the post-uprate period. Area SL2 had a higher mean CPUE than the other two areas during the summer pre-uprate period, but was intermediate between the other two areas during the summer post-uprate period. For winter sampling events, the mean CPUE in SL2 was intermediate between the means in the other two areas during both the pre- and post-uprate periods.
| |
| Twelve CRI decapods crustaceans were collected in trawls. Four taxa, roughneck shrimp (Rirnapenaeus sp.), speckled swimming crabs (Arenaeus cribrarius), pink shrimp (Farfantepenaeusduorarun), and roughneck shrimp (Rimapenaeus constrictus) made up over 82% of all CRI crustaceans captured (Table 22). Mean CPUE for CRI invertebrates ranged from 0.80/km in Area SL3 (post-uprate winter events) to 6.84/km in Area SL3 (pre-uprate summer events; Table 36). Mean CPUE for CRI decapod crustaceans for Area SL2 was slightly lower than the means for the other two areas during the summer pre-uprate sampling period, but intermediate to the other two areas during the other three sampling periods. There were no statistically significant differences in mean CPUE among areas prior to or after the uprate or within any area comparing pre- and post-uprate monitoring periods (Table 23 and Table 24).

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Gill Netting Eighty-nine (89) taxa, representing 76 fish, 6 crustaceans, and 7 miscellaneous taxa, were collected by gill net sampling (Table 37). A total of 4,580 organisms were identified and enumerated from the collection (4,461 fish, 34 crustaceans, 84 echinoderms, and 1 mollusc).
| |
| The 10 most abundant species accounted for 78% of the catch, with three species, Atlantic sharpnose shark (Rhizoprionodon terraeno'ae; 17.1%), Atlantic bumper (17.0%), and bonnethead shark (Sphyrna tiburo; 16.5.0%), accounting for over half of all captures. All II RIS of fish were captured by gill net, and collectively they accounted for 22% of all fish collected during the first 14 sampling events. Atlantic Spanish mackerel (Scomberomorus maculants) and Atlantic croaker (Micropogoniasundulatus) were the most abundant RIS.
| |
| There were no statistically significant differences in the number of fish taxa among areas prior to the uprate (Table 38). After the uprate, statistical analysis indicated that the number of fish taxa in Area SL2 was significantly less than the number in Area SLI, but not significantly different from the number in Area SL3. There were no statistically significant differences in the number of RIS fish taxa among areas during either pre- or post-uprate sampling periods. Within areas, there were no statistically significant differences in the number of fish taxa between pre- and post uprate sampling events in Areas SLI or SL2, though the number of pre-uprate fish taxa in SL3 was found to be significantly higher than the post-uprate number (Table 39). There were no statistically significant differences in the number of RIS fish taxa between pre- and post-uprate events in any area.
| |
| Atlantic sharpnose sharks had the highest CPUE of all fishes (6.72/hr) followed by Atlantic bumper (6.68/hr), bonnethead sharks (6.49/hr); Table 40). The mean CPUEs for all fishes caught by gill net in pre-uprate events ranged from 36.10/hour in SLI winter events to 63.73/hour in SL3 winter events (Table 41). For all areas, mean CPUE for post-uprate events were lower than for pre-uprate events. Though SL2 had lower mean CPUE values than either of the reference sites during both pre- and post-uprate summer events, SL2 had a greater mean CPUE than SLI during pre-uprate winter events and a higher mean than both reference sites during post-uprate winter events. There were no statistically significant differences in mean fish CPUE among areas during pre- or post-uprate events (Table 38). Within each area, there were no statistically significant differences in fish CPUE between pre- and post-uprate events (Table 39).
| |
| There was considerable fluctuation in the number of RIS specimens captured between pre- and post-uprate events in all areas, particularly during the summer (Table 42). Area SL2 was intermediate between the reference sites in pre-uprate summer seasons. During post-uprate summer events only two RIS specimens were collected in each of the reference sites and none were collected in SL2. For winter events, the number of RMS specimens in SL2 was lower than in either reference site during pre-uprate period but higher than either reference site during post-ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 16

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY uprate period. The relationships among areas described for the number of RIS specimens is the same as the relationship based on mean CPUE of RIS (Table 43). There were no statistically significant differences in RIS CPUE among areas before or after the uprate (Table 38).
| |
| Furthermore, there were no statistically significant differences in RIS CPUE between pre- and post-uprate events within any area (Table 39).
| |
| With regard to mean CPUE of individual taxa of RIS, only one of eleven taxa exhibited any statistically significant differences among areas. During post-uprate monitoring, the mean CPUE of clupeiformes was statistically significantly higher in Area SLI than Area SL3, however, the SL2 mean was not statistically significantly different from means in either other area (Table 44).
| |
| Though there were statistically significant decreases in mean CPUEs for two RIS taxa, Atlantic croaker (Micropogoniasundulatus) and bluefish (Pomatomus saltatrix), between pre-uprate and post-uprate events, those decreases were only observed in Areas SLI and SL3 (Table 45). There were no statistically significant differences in mean CPUEs of any RIS taxa between pre- and post-uprate events in SL2.
| |
| The mean total lengths (TL) for each taxon of RIS collected in gill net sampling are presented in Table 46. The species with the greatest mean TL included Atlantic Spanish mackerel (476.4 mm), bluefish (Pomatornus saltatrix; 409.4 mm), and Gulf kingfish (Menticirrhus littoralis; 377.7 mm).
| |
| Mean weights and total biomass for RIS collected within each area during gill netting are presented in Tables 47 and 48, respectively. Atlantic Spanish mackerel (Scomberomorus maculatus) accounted for 41% (173.0 kg) of the total biomass for all RIS collected in gill net sampling, with blue fish (Pomatoinus saltatrix; 67.3 kg), Atlantic croaker (Micropogonias undulates; 50.0 kg), and yellowfin menhaden (Brevoortia smithi; 41.3 kg) accounting for another 38%. Area SL2 total RIS biomass was intermediate to values in the two reference sites during summer pre-uprate events (Table 49). Post-uprate summer samples had very few RIS taxa captured in any area so biomass was very low in all areas. During winter events, total RIS biomass in SL2 was lower than in either reference site during the pre-uprate period, but higher than either reference site during the post-uprate period. There were no statistically significant differences in mean RIS biomass among areas before or after the uprate (Table 38) or between pre- and post-uprate events in any area (Table 39).
| |
| The only CRI invertebrate captured in gill net sampling was the speckled swimming crab, which was represented by only 15 specimens (Table 37). Too few were captured to allow for meaningful statistical analyses.

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Beach Seining Fifty-five (55) taxa, representing 49 fish and 6 crustaceans, were collected during beach seine sampling (Table 50). For all events combined, a total of 26,722 organisms were identified and enumerated firom the collection (26,676 fish and 46 crustaceans). The scaled sardine (Harengula jaguana), was by far the most abundant species (19,726 individuals), accounting for 74% of all specimens collected. Three additional taxa, sand drum (Umbrina coroides), Atlantic bumper (Chloroscombrus chiysurus) and Spanish sardine (Sardinellaaurita), were each represented by more than 1,000 individuals, and collectively these four taxa accounted for 87% of all fish caught. Since beach seining does not have a method of normalizing the data using CPUE and there are unequal numbers of pre- and post-uprate events, numbers of individuals captured per event are used for comparisons (Table 51). Based on the mean number of fish captured per event, the value in SL2 was lower than the values in the other two areas during the summer pre-uprate events, but intermediate to the values in the other two areas during the summer post-uprate events (Table 52). During winter events, the mean number of fish per event was higher in SL2 than the other areas pre-uprate and lower than both those areas post-uprate. There were no statistically significant differences in mean numbers of fish or fish taxa among areas either prior to or after the uprate regardless of whether or not Harengulajaguanawas included (Table 53).
| |
| Furthermore, there was no statistically significant difference between pre- and post uprate means within any area (Table 53).
| |
| Eighteen taxa of RIS were among the fish captured by beach seine. Of these, Clupeiformes (represented by 11 species of sardines, herrings, and anchovies) was the most abundant, accounting for 90% of the total catch (Table 54). There were no statistically significant differences in the number of RIS taxa among areas or between pre- and post-uprate events within any area (Tables 53 and 55).
| |
| A large proportion of total RIS captures (78%) occurred during a single event (August 2012) in a single area (SL3), due primarily to large numbers of scaled sardines (Harengulajaguana).
| |
| Despite this large catch of scaled sardines, there were no statistically significant differences in the mean numbers of RIS among areas during pre- or post-uprate events (Table 53). When scaled sardines were excluded from statistical analyses, there were no significant differences among areas during pre-uprate events, but during post-uprate events SL3 had a significantly higher mean number of RIS fish than SLI and SL2. There was no statistically significant difference in the post-uprate means for SLI and SL2. There were no statistically significant differences within areas between pre- and post-uprate number of RIS fish (Table 55).

| When numbers of individual taxa of RIS were compared among areas, no statistically significant differences were found among areas during either pre- or post-uprate events (Table 56). Also, ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 18

| Total biomass for RIS collected within each area during baseline beach seining, are presented by area in Table 59. Scaled sardines accounted for 74% (160.1 kg) of the total RIS biomass. The addition of sand drum (25.3 kg), Gulf kingfish (15.1 kg), Spanish sardine (5.5 kg), and Florida pompano (Trachinotus carolinus;4.7 kg) elevate the combined percentage of total RIS biomnass to 98%. Among study areas, mean biomass ranged from 5.2 kg in Area SL2 to 382.0 kg in Area SL3 (Table 60). There were no statistically significant differences in RIS biomass among areas during either pre- or post-uprate events, with or without the inclusion of the single episodic event of scaled sardine (Table 53).

| Five taxa of CR1 decapod crustaceans were captured during baseline beach seine sampling, the speckled swimming crab, three taxa of mole crabs (Albuneidae, Emerita sp., and Ernerita talpoida), and the spiny lobster (Panulirusargus) which collectively accounted for 46 specimens (Table 50). The mole crabs were only captured in Area SL3 during the pre-uprate period, but in all areas during the post-uprate period. Arenaeus cribrariuswas collected in all areas. There were too few specimens of CR! decapod crustaceans captured to allow for meaningful statistical analyses.
| |
| PlanktonNetting One hundred seventy-five (175) taxa of fish (140), crustaceans (25), and fish eggs (10), were collected by plankton nets (Table 61). A total of 58,083 organisms were identified and enumerated from the collection (5,138 fish, 8,176 crustaceans, and 44,769 fish eggs). Not all fish and fish eggs could be identified to species level, so RIS were not included in the statistical analysis. However, 2,410 fish larvae could be identified as Clupeiformes, which is a RIS, and it accounted for 47% of all fish larvae collected. Collectively, 8 taxa comprised over 75% of the ichthyoplankton captured during plankton tows, including members of the families Blennidae, Clupeidae, Engraulidae, Gobiidae, and Sciaenidae. All species of Clupeidae, as well as some taxa within the Sciaenidae are RIS.

| All events combined, Area SL2 had an intermediate total number of larval fish captured (2079),
| |
| with SLI having the highest (2,168) and SL3 having the lowest (891, Table 62). The numbers of larval fish in SL2 were higher than in the other two areas during all but the pre-uprate winter events when the number was intermediate to the other two areas.

| |
| | |
| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY winter events had the largest number of larval fish collected by plankton netting, all taxa combined (1,260). This number is primarily due to a large number of Clupeidae larvae (Table 61).
| |
| The mean CPUE (number collected per 100 m3 of water filtered) for each taxon collected by plankton nets is presented in Table 63. For summer events, mean CPUE of all taxa (fish and CRI crustacean larvae and fish eggs) in SL2 was intermediate to the means for the other two areas prior to the uprate and greater than the means for the other two areas after the uprate (Table 64).
| |
| For winter events, mean CPUEs were similar among areas before and after the uprate.
| |
| For summer events, fish larvae CPUEs were higher in SL2 than the other two areas both before and after the uprate (Table 67). For winter events, fish larvae CPUE in SL2 was intermediate to the values in the other two areas prior to the uprate, but higher than the other two areas after the uprate. Differences in the mrean number of fish larvae taxa and mean fish larvae CPUE were not statistically significant among areas either before or after the uprate (Table 65). Furthermore, there were no statistically significant differences in the mean number of fish larvae taxa or mean fish larvae CPUE between pre- and post-uprate events within any area (Tables 66).
| |
| There was some variation in the relationship among areas with respect to mean CPUE for fish eggs, however, when all events were combined the mean for SL2 was greater than the means for the other two areas (Table 68). Differences in the mean number of fish egg taxa and CPUE among areas were not statistically significant before or after the uprate (Table 65). There were no statistically significant differences in fish egg CPUE between pre- and post-uprate events within any area (Table 66). Though there were no statistically significant differences in mean number of fish egg taxa between pre- and post-uprate events within either SLI or SL2, the mean within SL3 was statistically significantly higher during pre-uprate events (Table 66).
| |
| A relatively large number of CRI decapod crustacean larvae were captured during plankton collections, with five taxa comprising over 75% of the crustaceans captured, including the swimming crabs (Callinectes sp.), mole crabs (Albunea sp. and Emerita talpoida), blue crabs (Callinectes sapidus), and stone crabs (Menippe mercenaria) (Table 61). The mean CPUE for each CRI crustacean taxa captured by plankton nets is presented in Table 63. The mean CPUE for CRI crustacean larvae over all sampling events combined ranged from 11.00 in Area SLI to 15.26 in SL2 (Table 69). Differences in CRI crustacean larval taxa and CPUE among areas were not statistically significant among areas for any time period (Table 65). Furthermore, there were no statistically significant differences in CRI crustacean taxa or CPUE between pre- and post-uprate events within any area (Table 66).

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY NearshoreHardbottom Utilization by Sea Turtles The mean number of green turtle sightings was consistently higher in Area SL2 than the other two areas during both pre-uprate and post-uprate sampling periods (Table 70). Combining data from all events, the average green turtle sightings per one-kilometer-long transect ranged fi'om 0.04 at SL3 to 2.54 at SL2. Statistical comparisons among areas indicated that the mean number of green turtle sightings at Area SL2 was significantly greater than the means at the other two areas during pre-uprate events, but not significantly different from those areas during post-uprate events (Table 71). This change in the relationship among areas appears to be due to slight increases in SLI and SL3 and a slight decrease in SL 2 between pre- and post-uprate events.
| |
| These changes in mean numbers of green turtle sightings between pre- and post-uprate events within areas were not statistically significant (Table 72).
| |
| DISCUSSION The purpose of baseline monitoring during implementation of the Biological POS was to establish background conditions against which to assess the effects of the St. Lucie Plant EPU.
| |
| Monitoring was not intended to document effects of prior plant operations, as results of previous 316(a) studies concluded that operation of the St. Lucie Plant was not jeopardizing the protection and propagation of a balanced, indigenous population of shellfish, fish and wildlife in receiving waters of the Atlantic Ocean. Rather, the Biological POS is designed solely to assess the effects of a minor, elevation in discharge water temperatures on faunal communities following completion of the EPU. This report summarizes the results through the first year of post-uprate monitoring and provides preliminary comparisons of water quality and biological variables before and after the uprate. An additional year of post-uprate monitoring will be conducted and a final report will summarize the results of the entire study period.
| |
| Collectively, data collected to date indicate a diverse fish and shellfish community in nearshore waters of the Atlantic Ocean offshore the St. Lucie Plant. These faunal communities as well as the monitored water quality parameters exhibit considerable spatial and temporal variability.
| |
| Results of analyses of water quality data indicated that there were no statistically significant differences among areas before or after the uprate with respect to temperature, salinity or specific gravity. In the case of pre-uprate nighttime surface DO, the mean for the northern reference site was found to be statistically significantly higher than the mean for the southern reference site but there were no statistically significant differences in means between the power plant area and either reference site. Furthermore, no statistically significant differences were found among areas for pre-uprate daytime surface DO or for either daytime or nighttime post-uprate DO values. Though post-uprate surface and bottom pH values were statistically significantly higher in the north reference site than the power plant site for daytime events, neither surface or bottom ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 21
| |
| | |
| PRELIMINARY FINDINGS, ST. LucIE PLANT EPU BIOLOGICAL PLAN OF STUDY means at the power plant site statistically significantly differed from corresponding means in the south reference site. Furthermore, during nighttime sampling there were no statistically significant differences in surface or bottom pH values among areas. Taking all results into account, there was no indication that water quality was affected by the uprate.
| |
| For trawl samples, there were no statistically significant differences in the number of fish taxa, RIS taxa, or CRI invertebrate taxa among areas before or after the uprate. Furthermore, there were no statistically significant differences among areas before or after the uprate with respect to fish, RIS, or CRI invertebrate CPUE or the CPUE of individual RIS taxa. When Engraulidae was included there were no statistically significant differences in mean RIS fish biomass among areas prior to the uprate. After the uprate, statistical tests indicated that mean RIS fish biomass was significantly higher in the north reference site than the south reference site, but the power plant site was not significantly different from either reference site. When Engaulidae was excluded, there were no statistically significant differences among areas before or after the uprate. Based on these results there is no indication that the uprate affected the fish, RIS, or CRI invertebrates collected by trawl.
| |
| With respect to gill net sampling, there were no statistically significant differences in the number of fish taxa among areas prior to the uprate. After the uprate, statistical analysis indicated that the number of fish taxa at the power plant site was significantly less than the number in the north reference site, but not significantly different from the number in the south reference site. There were no statistically significant differences in the number of R1S fish taxa among areas during either pre- or post-uprate sampling periods. For fish and RIS CPUE, there were no statistically significant differences among areas prior to or after the uprate. With regard to mean CPUE of individual taxa of RIS, only one of eleven taxa exhibited any' statistically significant differences among areas. During post-uprate monitoring, the mean CPUE of clupeiformes was statistically significantly higher in the north reference site than the south reference site, however, the mean CPUE at the power plant site was not statistically significantly different from means in either other area. There were no statistically significant differences in mean RIS biomass among areas either before or after the uprate. As with the results of trawl collection analyses, there is no indication of an uprate affect on fish or RIS collected by gill nets. Too few CR1 invertebrates were collected by gill net for any meaningful comparisons.
| |
| There were no statistically significant differences in numbers of fish or RJS taxa collected by beach seine among areas before or after the uprate. Furthmore, the differences in the mean numbers of fish collected was not statistically significant among areas prior to or after the uprate, regardless of whether scaled sardines (Harengulajaguana) were included or excluded. There were no statistically significant differences in the mean numbers of RIS among areas during pre-or post-uprate events when scaled sardines were included. When scaled sardines were excluded, there were no significant differences among areas during pre-uprate events, but during post-uprate events the south reference site had a statistically significantly higher mean number of RIS fish than the north reference site and the discharge site. The post-uprate means for the north ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 22

| PRELIMINARY FINDINGS, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY reference site and the power plant site were not statistically significantly different. When numbers of individual taxa of RIS were compared among areas, no statistically significant differences were found among areas during either pre- or post-uprate events. There were no statistically significant differences in RIS biomass among areas during either pre- or post-uprate events, with or without the inclusion of scaled sardines. Collectively these results give no indication of an uprate affect on fish or RIS. Too few specimens of CRI invertebrates were collected by beach seine for any meaningful comparisons.
| |
| Differences in the mean number of fish larvae taxa, fish egg taxa, CRI invertebrate taxa, fish larvae CPUE, fish egg CPUE, and CRI invertebrate CPUE from plankton samples were not statistically significant among areas either before or after the uprate. These results provide no indication of an uprate effect on fish larvae, fish eggs, or CRI invertebrate larvae.
| |
| Statistical comparisons among areas indicated that the mean number of green turtle sightings at the power plant site was significantly greater than the means at the two reference sites during pre-uprate events, but not significantly different from those areas during post-uprate events. This change in the relationship among areas appeared to be due to slight increases in the reference sites and a small decrease at the power plant site between pre- and post-uprate events. None of these changes in mean numbers of green turtle sightings between pre- and post-uprate events within areas were statistically significant. Whether the change in the relationship among areas reflects an uprate effect or simply natural variability in the distribution of green turtles should be revealed by subsequent monitoring.
