==SUMMARY==
An Extended Power Uprate (EPU) was undertaken to increase the generating capacity and improve operating efficiency of Units 1 and 2 at Florida Power & Light Company's (FPL's) St.Lucie Plant on Hutchinson Island, St. Lucie County, Florida. The EPU was expected to result in a slight increase (2.0&deg;F; 1.1 V&deg;C) 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 formally approved by the Florida Department of Environmental Protection (FDEP) on August 18, 2011, and study implementation began soon thereafter.
This report summarizes results of 8 baseline (pre-uprate) and 12 post-uprate monitoring events conducted from August 2011 through February 2015. All sampling was conducted under a Florida Fish and Wildlife Conservation Commission Special Activities License (most recently SAL-14-0071-SR) issued to Ecological Associates, Inc.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 habitat.Monitoring was performed approximately every other month. Three discrete study sites, one centered around the plant within the zone of thermal influence (SL2) and two reference/control sites located north (SL I) and south (SL3) of the plant, were used throughout the study.Water quality data were collected during each sampling event, and resultant Event Reports were previously provided to FPL. These data represented only a snapshot of water quality conditions over a period of just a few days during each event, with only six sampling events per year conducted at each study site. Thus, no analyses could be performed that would allow meaningful inferences regarding the effect of the EPU on water quality.Clupeiform fish (anchovies, herrings, and sardines), a Representative Important Species (RIS), accounted for over 38% of the total catch from trawl sampling.
The species comprising this group provide forage food for a large variety of predatory fish, many of which are commercially and recreationally important.
Sixteen (16) Commercially/Recreationally Important (CRI)decapod crustacean taxa were also collected by trawl during pre- and post-uprate sampling.There were no statistically significant differences in the mean number of fish, RIS, or CRI decapod crustacean taxa among study sites either before or after the uprate. Likewise, there were no statistically significant differences among areas during baseline monitoring with respect to the mean Catch per Unit Effort (CPUE) for any of these groups or for individual RIS taxa.Although, CPUEs for fish and RIS captured by trawl during post-uprate sampling at the discharge site were significantly lower than comparable values at the northern control, they did not differ significantly from the southern control. There were no statistically significant ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA ii differences between the discharge site and either control site with respect to the mean biomass of RIS captured before or after the uprate. Finally, none of the biological variables analyzed from trawl data at the discharge site differed significantly between pre- and post-uprate sampling periods. Thus, there is no indication that the uprate affected the benthic fish, RIS, or CRI invertebrate communities in the vicinity of the St. Lucie Plant.Gill-net sampling primarily targeted fish, including many RIS. Atlantic sharpnose shark, Atlantic bumper, bonnethead shark, and spot collectively accounted for over half of all captures.
The most abundant RIS were spot, Atlantic croaker, and Atlantic Spanish mackerel.
As with trawl sampling, there was considerable variability in the number of taxa and CPUE per sampling event. However, there were no statistically significant differences in the mean number of fish taxa, RIS taxa, fish CPUE, RIS CPUE, CPUE for individual RIS taxa, or RIS biomass among study sites during either pre- or post-uprate sampling periods. Furthermore, none of the biological variables analyzed from gill net data at the discharge site differed significantly between pre- and post-uprate sampling periods. Thus, there is no indication that the EPU had an effect on water column fish assemblages in the vicinity of the St. Lucie Plant.As for other sampling methods, there was considerable variability among sampling events with respect to the number of taxa and, in particular, the number of individuals captured by beach seine. This was due mainly to a large catch of scaled sardines at the southern control site during two sampling events. Throughout the entire study period, that species accounted for 68% of all specimens collected by seine. Sand drum, Atlantic bumper, tidewater mojarra, and Spanish sardine also occurred in relatively high numbers.There were no statistically significant differences among study sites in the mean number of fish taxa, RIS taxa, number of fish captured per event, number of RIS captured per event, number of each RIS taxa, or RIS biomass collected by beach seine either before or after the uprate. These results persisted regardless of whether scaled sardines were included or excluded from the analyses.
Furthermore, none of the biological variables analyzed from beach seine samples at the discharge site differed significantly between pre- and post-uprate sampling periods.Collectively these results give no indication of an uprate affect on surf zone fish in the vicinity of the St. Lucie Plant.Numerous taxa of fish and CRI crustacean larvae and large quantities of fish eggs were collected during plankton sampling.
The family Clupeidae dominated the larval fish collections, accounting for 39% of all fish larvae captured.
Mole crabs in the genus Albunea dominated CRI crustacean larvae, accounting for 30% of all specimens captured during plankton sampling.
As with other biological sampling, there was considerable variability among sampling events.However, none of the differences among study sites 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 from plankton samples were statistically significant either before or after the uprate. Nor were there any significant differences in these variables at the discharge site between pre- and ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA iii post-uprate sampling periods. These results provide no indication of an uprate effect on planktonic stages of fish and CRI invertebrate larvae in the vicinity of the St. Lucie Plant.The mean number of green turtles sighted within the discharge site was significantly greater than the means in either control during pre-uprate events, but only significantly higher than the southern control during post-uprate events. This change in the relationship among study sites appeared to be due to a slight increase in sightings at SLI following the uprate and a small corresponding decrease at the discharge site. However, none of these changes were statistically significant within any study area, including the discharge, indicating that the EPU had no effect on the number of small green sea turtles utilizing nearshore hardbottom habitat in the vicinity of the plant.Data collected during the St. Lucie Plant Biological POS characterize a diverse and abundant fish and shellfish community in nearshore waters of the Atlantic Ocean offshore the St. Lucie Plant. These communities are extremely dynamic in terms of spatial and temporal variability.
Although there were occasional statistically significant differences in faunal conditions between the discharge site and one of the controls, SL2 never differed significantly from both controls.The lack of significant differences among sites for most variables, and the lack of significant differences between pre- and post-uprate sampling at the discharge site indicate the absence of a measureable EPU effect on local fish and wildlife populations in the vicinity of the St. Lucie Plant. Given the huge capacity of the receiving water body (Atlantic Ocean) to dissipate heat, the effectiveness of the offshore discharge pipes in diffusing heated cooling water, the limited spatial area historically affected by thermal discharges, and the small change in discharge temperatures resulting from the uprate, these findings are not unexpected.
ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA iv FINAL REPORT, 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 &deg;0 C) under normal operating conditions, resulting from an extended power uprate (EPU) for 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 shortly thereafter.
Following receipt of review comments in May 2011, a final Plan was submitted to the Department on June 1, 2011; it was formally approved on August 18, 2011.The Biological POS for the St. Lucie Plant EPU was intended to characterize the fish and shellfish fauna in the vicinity of the plant, and assess the extent, if any, to which the EPU affected those communities.
As described below, the Plan consisted of trawling, gill netting, beach seining, plankton netting, and monitoring of sea turtle utilization of nearshore hardbottom.
Sampling techniques largely replicated those used in prior 316(a) demonstration studies at the St.Lucie Plant to provide comparable contemporary data.The Biological POS called for baseline monitoring prior to completion of the EPU, and two years of post-uprate monitoring.
Results of all individual pre- and post-uprate sampling events were previously reported to FPL. This final report, as required by the AO, compiles and summarizes those results and compares pre- and post-uprate data between seasons and among study sites to assess EPU effects.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY 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. Post-EPU monitoring continued through February 2015. Sampling was perfonned every other month for a total of 8 baseline sampling events and 12 post-uprate events. All sampling was conducted under a Florida Fish and Wildlife Conservation Commission Special Activities License (most recently SAL-14-0071-SR) issued to Ecological Associates, Inc.General Sampling Areas Three separate sampling sites were established within the study area, each measuring approximately 2.0 mi (3.2 km) 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 km) 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 SL2 and positioned similarly served as reference/control sites to document "natural" 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.Specific Sampling Locations Within each of the three study sites, three transects progressively distant from shore were established for gill net and trawl sampling.
The transects were located approximately 600 ft (183 ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 2 FINAL REPORT, ST. LuCwe PLANT EPU BIOLOGICAL PLAN OF STUDY 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 km) from shore in water depths of 34-45 ft (10.4-13.7 in; 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 sites. Station A was located approximately 0.5 mi. (0.8 km) north of the center of each site, Station B was located at the center of the site, and Station C was located approximately 0.5 mi. south of the center of the site (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 study sites. 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 (fC), salinity as a function of conductance (practical salinity units [PSU]), dissolved oxygen (DO), 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 study site, yielding a total of 72 baseline and 108 post-uprate samples. Sampling was conducted with a 16-ft (4.9-m) by 3-ft (0.9 m) semi-balloon bottom trawl, having a 0.5-in (12.7 rmm) stretch mesh in the bag and 0.25-in (6.4-mm) 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 approximate midpoint of each of the three gill net transects (Figure 2). Trawl 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 ECOLOGICAL ASSOCIATES, INC., JENSEN BEAcn, FLORIDA 3 FINAL REPORT, ST. LuciE PLANT EPU BIOLOGICAL PLAN OF STUDY 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 study site, yielding a total of 72 baseline and 108 post-uprate samples. Within the discharge 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 m) 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 allowed 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. Gill net 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 entered 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 obtained for those specimens.
Gill net data is presented as described above for trawl samples 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 captured.Beach Seining Beach seining was conducted at three locations within each of the three study sites, yielding a total of 72 baseline and 108 post-uprate samples. The seine consisted of a 100-ft (30.5-m) long ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 4 FINAL REPORT, ST. LuCE PLANT EPU BIOLOGICAL PLAN OF STUDY by 6.0 ft (1.8-m) deep net having a stretch mesh of I inch (25 mm). The net was heavily weighted along the bottom and had extra floatation on the top so it maintained 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 m), deployed parallel to shore and then pulled onto the beach with the ends roughly perpendicular to shore. This created a horseshoe-shaped barrier, with fish funneled to the central part of the net as it was brought on shore. Beach seining 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 site (Figure 2), yielding a total of 48 baseline and 96 post-uprate samples. Sampling was conducted using paired bongo nets with a mouth opening of 7.9-in (20-cm) diameter, and fitted with a 0.02 in (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, any captured CRI decapod crustacean larvae were identified and enumerated.
CR1 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 meters of water filtered (CPUE).Nearshore Hardbottom Utilization by Sea Turtles A single 0.62-mi (1-kim) shore-parallel transect was monitored in each of the three study sites.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 96 post-uprate observations were made. Sea turtle surveys were performed from a boat equipped with an elevated platforn 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 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).ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 5 ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 5 FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Representative Important Species 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 fish taxa and one species of sea turtle, as follows: 1. Atlantic croaker (Micropogonias undulalus) 
-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 chrysoptera) 
-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 (Pomatonius saltairix) 
-This commercially 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 prior studies at the plant. Seatrout are bottom associated species that spawn offshore, and gravid females have been found throughout the year.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 6 FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY 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 (Trachinotus 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 maculatus) 
-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 mydas) -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.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 7 FINAL REPORT, ST. LucRE PLANT EPU BIOLOGICAL PLAN OF STUDY Statistical Analysis 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).Water quality data was not statistically analyzed due to the time spans between sampling and the natural short term variability of the measured parameters.
Faunal data did not meet the conditions for parametric testing and therefore non-parametric tests were used for all analyses.Separate analyses were 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 CRI decapod crustacean larvae, as applicable.
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 only. All data were analyzed using a Kruskal-Wallis Analysis of Variance by Ranks Test (ANOVA) to determine if statistically significant differences (p<0.0500) existed among sites, season, or pre- and post-uprate events. If significant differences were detected, the Multiple Comparisons of Mean Ranks Post-hoc Test was used to determine which paired values were significantly different.
In certain instances, the ANOVA and the Multiple Comparisons Tests produced conflicting results (i.e. the ANOVA indicated the presence of significant differences, but the Multiple Comparisons Test did not indicate any significant differences for any of the pair-wise comparisons).
In these cases, a Mann-Whitney U Test was perfonned to determine which areas (SL1 vs. SL2, SL2 vs. SL3 and SLI vs. SL3) differed significantly from each other.Seasonal changes and/or long-term temporal patterns were assessed by analyzing for differences among seasonal sampling events. For the purpose or these analyses the sampling events were grouped into either summer (May through October) or winter seasons (November through April).During the study period, an abnormally large number of individuals of a single taxon were occasionally captured during a sampling event at one or more stations.
For these events, the data were statistically analyzed both including and excluding the anomalous catch to assess its effect on a test outcome.RESULTS Water Quality Differences in time of day, tidal stage, and weather conditions both between and during each sampling event created considerable spatial and temporal variability in water quality parameters and precluded any meaningful statistical analyses.
Nevertheless, a few general characterizations ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH., FLORIDA 8 FINAL REPORT, ST. LucIE PLANT EPU BIOLOGICAL PLAN OF STUDY can be made regarding seasonal differences in measured variables among study sites pre- and post-uprate.
Data are presented in relation to the associated sampling method: daytime bottom and surface values for gill netting and nighttime bottom and surface values for trawling/plankton tows.Dissolved Oxygen Gill Netting -Mean bottom DO during daytime sampling ranged from 5.89 to 6.51 mg/L and averaged 6.29 mg/L for all areas and seasons combined (Table 1). During the summer, mean bottom DO declined within all three study areas following the EPU, and differences among study sites were minor. Similar patterns were detected for mean surface DO, which ranged from 5.94 to 6.74 mg/L and averaged 6.40 mg/L for all areas and seasons combined (Table 2).Trawt'ling 
-Mean bottom DO during nighttime sampling ranged from 6.09 to 6.68 mg/L and averaged 6.36 mg/L for all areas and seasons combined (Table 3). Mean surface DO ranged from 6.11 to 6.69 mg/L and averaged 6.40 mg/L for all areas and seasons (Table 4). As for gill netting stations, mean DO was higher in the winter than during the summer, but differences among study sites or pre- and post-uprate seasonal events were minor.pH Gill Netting -During daytime sampling, mean bottom pH ranged from 7.87 to 8.20, with a mean value of 8.08 for all areas and seasons combined (Table 5). Mean surface pH ranged from 7.87 to 8.17 and averaged 8.06 for all areas and seasons combined (Table 6). Mean values for daytime surface and bottom pH showed little variation among sites, seasons, or pre- and post-uprate sampling.Tracling -During nighttime sampling, mean bottom pH ranged from 8.00 to 8.16, with a mean value of 8.10 for all areas and seasons combined (Table 7). Mean surface pH for trawls ranged from 7.99 to 8.14 and averaged 8.09 for all areas and seasons combined (Table 8). pH data collected during trawling were very similar to those reported for gill netting.Salinity Gill Netting- Mean bottom salinity during daytime sampling ranged from 35.51 to 36.37 PSU, with a mean value of 36.05 PSU for all areas and seasons combined (Table 9). Mean surface salinity ranged from 35.50 to 36.31 PSU and averaged 36.01 PSU for all areas and seasons combined (Table 10).ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 9 FINAL REPORT, ST. LuciE PLANT EPU BIOLOGICAL PLAN OF STUDY Trawling -Mean bottom salinity during nighttime sampling ranged from 35.64 to 36.51 PSU, with a mean value of 36.01 PSU for all areas and seasons combined (Table 11). Mean surface salinity ranged from 35.60 to 36.55 PSU with a mean of 36.00 PSU for all areas and seasons (Table 12). Mean salinity values showed little variation among sites, either pre- or post-uprate and were typical of oceanic conditions..
Specific Conductivity Gill Netting -Mean bottom specific conductivity during daytime sampling ranged from 53.68 to 54.99 mS/cm, with a mean value of 54.58 mS/cm for all areas and seasons combined (Table 13). Mean surface specific conductivity ranged from 53.65 to 54.95 mS/cm and averaged 54.46 mS/cm for all areas and seasons (Table 14).Travling -Mean bottom specific conductivity during nighttime sampling ranged from 53.81 to 55.29 mS/cm and averaged 54.51 mS/cm for all areas and seasons combined (Table 15).Mean surface specific conductivity ranged from 53.75 to 55.30 mS/cm and averaged 54.44 mS/cm for all areas and seasons (Table 16). Mean specific conductivity values mirrored salinity data presented above, with little variation among sites, either pre- or post-uprate.
Temperature Gill Netting -Mean bottom water temperatures during daytime sampling ranged from 70.7 to 79.1&deg;F (21.50 to 26.15 0 C) with a mean of 75.4 0 F (24.10 0 C) for all areas and seasons combined (Table 17). Mean surface water temperatures for daytime sampling ranged from 71.3 to 81.2 0 F (21.84 to 27.35 0 C) with a mean temperature of 77.0&deg;F (24.98&deg;C) for all areas and seasons combined (Table 18).
-Mean bottom water temperature during nighttime sampling ranged from 70.9 to 79.8&deg;F (21.63 to 26.56&deg;C) and averaged 75.6 0 F (24.21&deg;C) for all areas and seasons combined (Table 19). Mean surface water temperature during nighttime sampling ranged from 71.8 to 80.7 0 F (22.09 to 27.05'C) and averaged 76.7 0 F (24.85&deg;C) for all areas and seasons combined (Table 20).Mean summer surface water temperatures increased at all study sites post-EPU, including a 2.3&deg;F (1.30&deg;C) increase at the discharge site. However, surface water temperatures at Control SLI to the north experienced similar increases:
2.2&deg;F (1.22&deg;C) during daytime gill net sampling and 2.4&deg;F (1.35&deg;C) during nighttime trawl sampling.
The greatest increase in mean summer bottom water temperatures between pre- and post-uprate sampling events (3.0'F; 1.66&deg;C)occurred during trawl sampling at the northern control, and the smallest increase (0.5&deg;F; 0.28 0 C)was found at the southern control, also during trawl sampling.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 10 FINAL REPORT, ST. Lucwe PLANT EPU BIOLOGICAL PLAN OF STUDY During winter sampling, mean surface water temperatures also increased at all sites during post-uprate gill net sampling, with the largest increase (2.7&deg;F; 1.48&deg;C) occurring at Control SLI, while the smallest change (0.9&deg;F; 0.53&deg;C;) was found at the discharge site. During winter trawl sampling, mean surface and bottom water temperatures were lower after the EPU, with the greatest decrease found at the bottom during nighttime trawling at the discharge site (-2.5&deg;F; -1.41-C).Trawling Table 21 provides the common and scientific names of all organisms captured for all sampling methods combined during pre- and post-uprate monitoring.
One hundred eighty four (184) taxa, representing 93 fish, 76 crustaceans, 10 echinoderms, and 5 molluscs, were captured by trawl (Table 22). A total of 7,530 organisms were identified and enumerated from the collections (2,078 fish, 3,803 crustaceans, 1,527 echinoderms, and 122 molluscs).
Nine (9) of the 11 RIS were represented in the catch, and collectively they accounted for 60% of all fish captured by trawl. Clupeiformes (anchovies, herrings, and sardines), represented primarily by unidentified Engraulids and the Cuban anchovy (Anchoa cubana), accounted for 38% of the total number of fish caught. The species comprising this taxon provide forage food for a large variety of predatory fish, many of which are commercially and recreationally important.
The sand drum, unidentified anchovy (Anchoa sp.), star drum (Steifer lanceolatus), and Atlantic bumper (Chloroscombrus chrysurus) were also caught in relatively high numbers. Collectively, these six taxa accounted for approximately 62% of the total catch.There were no statistically significant differences among study sites with respect to the number of fish, RIS, or CRI invertebrate taxa collected by trawl during pre-uprate, post-uprate, summer, or winter sampling, or when all sampling events were combined (Table 23). Similarly, there were no significant differences in the number of fish, RIS, or CRI invertebrate taxa collected between pre- and post-uprate sampling events within any study site, including the discharge (Table 24).Of the fish taxa collected by trawl, sand drum, Engraulidae, and Cuban anchovy had the greatest CPUE (2.39/km, 2.02/km and 2.01/km, respectively), while the vast majority (>76%) of the other fish taxa captured had a CPUE of 0.10 or less (Table 25). The mean CPUE for all fish taxa combined ranged from 1.63/kmn in the southern control during pre-uprate winter events to 74.43/km in the northern control during pre-uprate summer events (Table 26). The considerably higher mean CPUE for all areas during pre-uprate summer sampling is attributable to relatively high numbers of Clupeiform fish and sand drum captured during two events.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA I1I FINAL REPORT, ST. LucIE PLANT EPU BIOLOGICAL PLAN OF STUDY Overall, catches of fish during trawl sampling was higher during the summer than during the winter, and pre-uprate summer sampling yielded considerably higher CPUE for fish than post-uprate sampling, particularly at the discharge site (9.4 times higher; Table 26). In contrast, post-uprate CPUE for fish during the winter was higher than comparable pre-uprate values at all study sites.When the mean CPUE values for all fish taxa combined were compared among study sites, there were no significant differences during pre-uprate, summer, or winter sampling periods, or when all events were combined (Table 23). However, CPUE at Control SLI was significantly higher than CPUE at the discharge site (SL2) during post-uprate monitoring, but SL2 was not significantly different from the southern control (Table 23). Large catches of anchovies (Engraulidae) were responsible for a substantial amount of variation in the data. However, even after excluding anchovies from the statistical analyses, CPUE during post-uprate monitoring remained significantly higher at the northern control than at the discharge site, and the discharge site did not differ significantly from Control SL3 (Table 23). Furthermore, there were no significant differences in fish CPUE between pre- and post-uprate sampling periods, either including or excluding Engraulidae, within any study site, including the discharge (Table24).
Insofar as Clupeiformes, an RIS taxon, accounted for a large percentage of the total fish catch, seasonal patterns for RIS CPUE were similar to those for all fish species combined (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 of sampling can skew catch numbers. For example, Clupeiform fish accounted for 82% of all RIS captured during pre-uprate trawl sampling (Table 27), and all but one of those individuals was captured during a single sampling event (October 2012). Sixty-eight (68) percent and 23%, respectively, of all Clupeiformes captured during all pre- and post-uprate sampling events combined were caught in SLI and SL2, while only 9% were captured in SL3. Thus, it is not surprising that Control SLI had the greatest number of all RIS specimens captured (820), and Control SL3 had the fewest (207; Table 27). As mentioned earlier, sand drum, Engraulidae, and Anchoa cubana had the greatest CPUE (2.39/km, 2.02/km and 2.01/km, respectively; Table 28). The mean CPUE for all RIS taxa combined was 8.78/km.The mean CPUE for each RIS species was compared statistically among study sites and seasons.Due largely, to the high degree of spatial and temporal variability in the data, CPUE for Clueiformes did not differ significantly among any study sites pre- or post uprate, seasonally, or for all events combined (Table 29).The only significant differences in CPUE for RIS taxa were found for sand drum and leopard searobin.
The CPUE for sand drum during post-uprate trawl sampling was found to be significantly higher at Control SL1 than at the discharge site, but SL2 did not differ significantly from Control SL3. This same outcome was found for all events combined (Table 29).ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 12 FINAL REPORT, ST. LUCiE PLANT EPU BIOLOGICAL PLAN OF STUDY Furthermore, there were no significant differences in CPUE for sand dram between pre- and post-uprate events within any study site, including the discharge (Table 30).ANOVA of CPUE for leopard searobin indicated a significant difference among study sites during post-uprate monitoring.
However, neither the Multiple Comparisons of Mean Ranks Post-hoc Test nor the Mann-Whitney U Test were able to determine which sites were significantly different from one another (Table 29). Within-area comparisons revealed that this species was significantly more abundant before the uprate than after, but only at Control SL3 (Table 30).When captures were adjusted to account for variable tow distances, CPUE for all RIS taxa combined ranged from 54.24/km in Control SLI during pre-uprate summer events to 0.76/km at the discharge site (SL2) during post-uprate summer events (Table 31). Prior to the uprate, regardless of season, mean RIS CPUE at the discharge site was intermediate between comparable values at the two control sites. Prior to the uprate, CPUE for RIS during summer events was anywhere from 6 (SL3) to 34 times (SLI) higher than corresponding winter values at all study sites. Following the uprate, summer CPUE for RIS at the two control sites remained higher that corresponding winter values, although the differences were only about twofold. By comparison, winter CPUE values at the discharge site were double corresponding summer values.Mean CPUE for RIS during the summer decreased at both SLI and SL2 after the uprate, with the greatest decrease occurring at the discharge site. At SL3, post-uprate CPUE during the summer was slightly larger than the comparable pre-uprate value. During the winter, mean CPUE after the uprate increased at all study sites.When CPUE for RIS, all species combined, were compared statistically, Control SLI was found to have significantly higher RIS CPUE than the discharge site during post-uprate monitoring, but SL2 did not differ significantly from the southern control (Table 23). The difference between SLI and SL2 was largely attributable to differences in the number of Engraulidae in the catches, as its removal from the analysis resulted in no significant differences in RIS CPUE between those two sites (Table 23). There were no significant differences found in RIS CPUE, either including or excluding Engraulidae, among study sites during pre-uprate, summer, or winter sampling events, or when all events were combined (Table 23). Similarly, there were no statistically significant differences found within any study site when RIS CPUE was compared pre- and post-uprate (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 the Atlantic croaker (234.27 rmm), pigfish (233.00 mm), and silver seatrout (225.00 mm). The Clupeiforms, such as anchovies, were the smallest.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 13 FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Mean weights and total biomass for RIS collected within each study site during trawl sampling are presented in Tables 33 and 34, respectively.
Despite representing the greatest number of specimens captured by trawl during baseline sampling, Clupeifonnes represented only 17% of the RIS biomass.Many of the RIS taxa were not captured during all of the various sampling periods. For example, during the summer, 10 of the 13 taxa collected at Control SLI were only captured during pre- or post-uprate trawling, but not both. Similarly six of the nine RIS taxa collected during winter sampling at the northern control were only represented in pre- or post-uprate events, but not both. In other cases, an RIS taxon may have been captured during both pre- and post-uprate sampling periods, but only during one season. For example, Gulf kingfish were only captured during the summer at the southern contol, while Atlantic croaker were only captured during the winter at the northern control.During the winter, the mean weight for all RIS taxa combined was much lower during post-uprate trawl sampling than during pre-uprate monitoring at all study sites (Table 33). During the summer, mean weight decreased slightly at SLI following the uprate, while increasing slightly at the discharge site. At Control SL3, mean weight during pre-uprate summer sampling was nearly 24 times greater than during the comparable post-uprate sampling period.Total biomass reflects the total number of fish collected and the corresponding mean biomass for each RIS taxon captured.
Since there were unequal numbers of pre- (8) and post-uprate (12)sampling events, total biomass will yield biased results when assessing the effects of the EPU.Comparison of mean biomass removes that bias. The discharge site had a lower mean biomass than either control site during pre-uprate summer sampling, but was intermediate to the two controls during pre-uprate winter sampling.
During post-uprate sampling, mean biomass at SL2 was intermediate to the two control sites during the summer, but lower than both during the winter (Table 34). However, none of these differences were statistically significant.
Regardless of whether Engraulidae was included or excluded from the analysis, there were no statistically significant differences in mean RIS biomass among study sites during pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 23). Similarly, there were no statistically significant differences in mean RIS biomass, inclusive of Engraulidae, between pre- and post-uprate sampling periods within any study site (Table 24). The only significant within-area difference was found at SL3 when Engraulidae were excluded from the analysis; mean biomass was significantly greater during pre-uprate sampling than during post-uprate monitoring (Table 24).A total of 5,452 invertebrates represented by 91 taxa were collected by trawl during pre- and post-uprate sampling (Table 22). The largest total number of invertebrates were captured in SLI ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 14 FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY (2,695) and the fewest in SL3 (695; Table 35). Mean CPUE for all invertebrate taxa combined ranged from 6.34/km in SL3 during post-uprate winter sampling to 149.50/kin at the discharge site during pre-uprate summer sampling.
Means for SL2 and SL3 were higher during pre-uprate summer sampling than during the comparable post-uprate period, while the opposite was true for SLI. Pre- and post-uprate mean values were quite similar during both winter and summer sampling periods. The discharge site had a higher mean CPUE than the two control sites during the pre-uprate summer period, but it was intermediate to both controls during the comparable post-uprate period. For winter sampling events, the mean CPUE at the discharge site was intermediate to the means for the two controls during both pre- and post-uprate sampling periods.Eighteen (18) CRI decapod crustacean taxa were collected during trawl sampling.
Four of those, roughneck shrimp (Riniapenaeus constriclus), unidentified roughneck shrimp (Rimapenaeus sp.), pink shrimp (Fatfantepenaeus duorarum), and speckled swimming crabs (Arenaeus cribrarius) made up 77% of all CRI crustaceans captured (Table 22).Mean CPUE for CRI invertebrates ranged from 1.28/kim at SL1 during pre-uprate winter sampling to 7.48/km, also at SL1, during post-uprate summer events (Table 36). Mean CPUE for CRI decapod crustaceans captured by trawl at the discharge site was slightly lower than the means for the two controls during pre-uprate summer events, but intermediate to the controls during post-uprate sampling.
Mean CPUE for CRI invertebrates at SL2 was also intermediate to the two controls during both pre- and post-uprate winter sampling periods. However, none of these differences among study sites were statistically significant whether considering pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 23).Likewise, there were no statistically significant differences in the number of invertebrate taxa or CPUE for all taxa combined between pre- and post-uprate sampling periods within any study site (Table 24).Gill Netting One hundred (100) taxa, representing 84 fish, 8 crustaceans, 7 echinoderms, and I mollusc were collected during gill net sampling (Table 37). A total of 5,993 organisms were identified and enumerated from the collection (5,831 fish, 62 crustaceans, 99 echinoderns, and 1 mnollusc).
The 10 most abundant species accounted for 78% of the catch, with four species, Atlantic sharpnose shark (Rhizoprionodon terraenovae; 15.7%), Atlantic bumper (15.7%), bonnethead shark (Sphyrna tiburo; 14.0 %), and spot (6.6%) accounting for over half of all captures.
All 11 RIS of fish were captured by gill net, and collectively they accounted for 28.7% of all fish collected.
Spot and Atlantic croaker were the most abundant.The number of fish taxa, all species combined, captured by gill net during the summer was significantly higher at Control SL1 than at the discharge site, although SL2 was not significantly ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 15 FINAL REPORT, ST. LUCrE PLANT EPU BIOLOGICAL PLAN OF STUDY different from the southern control (Table 38). Similar results were obtained for all sampling events combined.
When, looking at RIS only, there were no statistically significant differences in the number of taxa captured among areas during pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 38). Similarly, there were no statistically significant differences in the number of fish taxa or RIS fish taxa captured between pre- and post-uprate sampling periods within any study site (Table 39).Atlantic sharpnose sharks had the highest CPUE for all fishes (6.08/hr) followed by Atlantic bumper (6.06/hr) and bonnethead sharks (5.40/hr; Table 40). The mean CPUE for all fishes caught by gill net in pre-uprate events ranged from 36.10/hour in SLI during the winter to 63.73/hour in SL3, also during the winter (Table 41). Mean CPUE during post-uprate sampling was lower than comparable pre-uprate values within all three study sites regardless of season.During the pre-uprate summer sampling, the discharge site had a lower mean CPUE for fish captured by gill net than either of the two controls, but it was intermediate to SLI and SL3 during pre-uprate winter sampling.
Following the EPU, the mean CPUE for fish captured by gill net at the discharge site was intermediate to the two controls during summer sampling and greater than both controls during winter sampling.None of the differences in mean fish CPUE among study sites were statistically significant whether considering pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 38). Similarly, there were no statistically significant differences in fish CPUE between pre- and post-uprate events within any study site (Table 39).There was considerable fluctuation in the number of RIS specimens captured by gill net between pre- and post-uprate events in all areas, particularly during the summer (Table 42). The discharge site was intermediate to the two control sites during pre-uprate summer sampling.During post-uprate summer events, all sites saw a decrease in the number of RIS captured, although the number caught at SL2 was greater than at either of the two controls.
During the winter, the number of RIS specimens captured at the discharge site was lower than at either of the control sites prior to the uprate, but higher than both during post-uprate sampling.The relationships among study sites described above for the number of RIS specimens captured by gill net are the same as those based on mean CPUE (Table 43). There were no statistically significant differences in RIS CPUE among areas during pre-uprate, post-uprate, summer, or winter sampling events, or when all events were combined (Table 38). With-area comparisons indicated that there were no significant differences in RIS CPUE between pre- and post-uprate sampling periods at the discharge site or Control SL3. However, RIS CPUE at Control SLI was significantly higher during pre-uprate monitoring than during post-uprate monitoring (Table 39).ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 16 FINAL REPORT, ST. LucwE PLANT EPU BIOLOGICAL PLAN OF STUDY No statistically significant differences were found among study sites with regard to mean CPUE of individual RIS taxa during pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 44). The only difference in mean CPUE for any RIS taxa within a study site was at SLI, where bluefish were significantly more abundant during pre-uprate sampling (Table 45).The mean total lengths (TL) for each taxon of RIS collected in gill net sampling are presented in Table 46. The largest species captured included Atlantic Spanish mackerel (470.0 mm), bluefish (409.9 mm), and Gulf kingfish (371.4 mm).Mean weights and total biomass for RIS collected within each study site during gill netting are presented in Tables 47 and 48, respectively.
Atlantic Spanish mackerel accounted for 42%(233.5 kg) of the total biomass for all RIS collected, with Atlantic croaker (80.4 kg), blue fish (80.0 kg), and spot (57.4 kg) accounting for another 39%. Mean MjS biomass at the discharge site was lower than at the two control sites during both summer and winter pre-uprate sampling periods (Table 49). Following the uprate, mean RIS biomass at SL2 was higher than either control. However, as for other variables when these data were analyzed statistically, none of the differences among study sites were significant whether considering pre-uprate, post-uprate, summer, or winter sampling events, or when all events were combined (Table 38). Likewise RIS biomass did not differ significantly between pre- and post-uprate sampling periods within any study site (Table 39).The only CRI invertebrate captured during gill net sampling was the speckled swimming crab, which was represented by 16 specimens (Table 37). Too few were captured to allow for meaningful statistical analyses.Beach Seining Seventy-six (76) taxa, representing 64 fish and 12 crustaceans, were collected during pre- and post-uprate beach seine sampling (Table 50). A total of 42,289 organisms were identified and enumerated from the collection (42,105 fish and 184 crustaceans).
The scaled sardine (Harengulajaguana) was by far the most abundant species (31,455 individuals), accounting for 75% of all specimens collected.
Four additional taxa, sand drum, Atlantic bumper, tidewater mojarra (Eucinoslomus harengulus), and Spanish sardine (Sardinella aurita), were each represented by more than 1,000 individuals, and collectively these five taxa accounted for 89%of all fish caught. In the absence of a reliable method of normalizing beach seine data, such as CPUE, and given the unequal numbers of pre- and post-uprate sampling events, the only metric available for assessing the effect of the EPU based on beach seining data was the mean number of individuals captured per event (Table 51).ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 17 FINAL REPORT, ST. LuCaE PLANT EPU BIOLOGICAL PLAN OF STUDY Fewer individuals, all species combined, were captured per beach seine event at the discharge site than at either control site during both pre- and post-uprate summer sampling periods (Table 52). During winter events, the mean number of fish captured per event was higher in SL2 than either control during pre-uprate sampling and intermediate between the two controls during post-uprate sampling.
By far, Control SL3 had the highest number of captures per event during summer sampling, both pre- and post-uprate, and that was attributable to the large numbers of scaled sardines caught at that location.Despite large spatial and temporal differences in the absolute numbers of fish captured during beach seining, when analyzed statistically no significant differences were detected among study sites in the mean number of fish per event whether analyzing pre-uprate, post-uprate, summer, or winter sampling periods, or all events combined (Table 53). These results were unaffected by the exclusion of scaled sardines from the analysis.
Likewise, there were no statistically significant differences in mean numbers of fish captured between pre- and post-uprate sampling periods within any study site (Table 54). Similar results were obtained when the number of fish taxa collected during beach seining was compared both among and within study sites (Tables 53 and 54).Twenty 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 91% of the total catch (Table 55). There were no statistically significant differences in the number of RIS taxa captured among or within study sites whether considering pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Tables 53 and 54).A large proportion of total RIS captures (83%) occurred during two events (August 2012 at Control SL3 and August 2014 at both SLI and SL3) due primarily to large numbers of scaled sardines.
Because of the high degree of temporal and spatial variability in the data, there were no statistically significant differences in the mean numbers of RIS captured per event either among or within study sites during pre-uprate, post-uprate, summer, or winter sampling periods, or when all were events combined (Table 53 and 54). The same results were obtained whether scaled sardines were included or excluded from the analysis.
When numbers of individuals of each RIS taxa were compared, no statistically significant differences were found either among or within study sites during pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 56 and 57).The mean total lengths (TL) for each taxon of RIS collected by beach seine are presented in Table 58. The species with the greatest mean TL included Spanish mackerel (255.33 mm), spot (236.00 mm), Atlantic croaker (199.25 mm), and Gulf kingfish (103.78 mm).ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 18 FINAL REPORT, ST. LuciE PLANT EPU BIOLOGICAL PLAN OF STUDY Mean weight and total biomass for RIS taxa collected by beach seine within each study site are presented in Tables 59 and 60, respectively.
Scaled sardines accounted for 77% (286.4 kg) of the total RIS biomass. The addition of sand drum (45.0 kg), Gulf kingfish (23.9 kg), Florida pompano (5.9 kg), and Spanish sardine (5.1 kg) elevate the combined percentage of total RIS biomass to 98%. Mean biomass for all RIS taxa combined ranged from 0.003 kg at the discharge site during pre-uprate winter sampling to 7.8 kg during at Control SL3 during pre-uprate summer sampling (Table 60).When scaled sardines were included in the statistical analysis, no significant differences were detected in RIS biomass either among or within study sites during pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 53 and 54).However, when that species was excluded from the analysis, mean biomass of all RIS taxa combined was significantly higher at the southern control than at the discharge site during winter sampling, while the discharge and Control SLI did not significantly from each other (Table 53).Seven 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 Emerita talpoida), the spiny lobster (Panulirus argus), swimming crabs (Callinectes sp.), and pink shrimp, which collectively accounted for 178 specimens (Table 50). Mole crabs, which burrow into the sand, are considered to be an opportunistic capture and the number captured does not accurately represent their relative abundance.
Speckled swimming crabs were collected in all areas. There were too few specimens of CRI decapod crustaceans captured by seine to allow for meaningful statistical analyses.Plankton Netting One hundred ninety one (191) taxa of different life stages of fish (162), crustaceans (19), and fish eggs (10), were collected by plankton nets (Table 61). A total of 80,908 organisms were identified and enumerated from the collection (6,874 fish, 11,517 crustaceans, and 62,517 fish eggs). Not all fish and fish eggs could be identified to species level, so differences in abundances of individual RIS taxa could not be statistically analyzed.
However, 51% (3,504) of all fish larvae were identified as members of the Clupeiformes.
Collectively, 10 taxa comprised over 75% of the ichthyoplankton captured during plankton tows, including members of the families Clupeidae, Gobiidae, Sciaenidae, Engraulidae, and Blennidae.
All species of Clupeidae, as well as some taxa within the Sciaenidae, are RIS.The total number of larval fish captured for all pre-and post uprate events combined was highest at Control SL 1 (2,990) and lowest at Control SL3 (1,217), with intermediate numbers (2,667)caught at the discharge site Table 62). The number of larval fish collected at the discharge site was higher than either control site during both pre- and post-uprate summer sampling periods, ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 19 FINAL REPORT, ST. LuciE PLANT EPU BIOLOGICAL PLAN OF STUDY but intermediate to the two controls during winter sampling.
The large number of larval fish captured at Control SLI during pre-uprate winter sampling (1,260) was attributable primarily to the presence of large numbers of Clupeidae (Table 61).The mean CPUE for each taxon collected by plankton nets is presented in Table 63. For summer events, mean CPUE for all taxa combined (fish larvae, fish eggs, and CRI crustacean larvae)collected at the discharge site was intermediate to the means for the two controls prior to the uprate and greater than both after the uprate (Table 64). During winter sampling, mean CPUEs at the discharge site were lower than both controls both before and after the uprate.When examining only fish larvae contained in the plankton samples, CPUEs were higher at the discharge site than at either control during the summer both before and after the uprate (Table 65). During winter sampling, fish larvae CPUE at the discharge was lower than the comparable values for the two controls prior to the uprate, but intermediate to the controls after the uprate.However, none of the differences among or within study sites were statistically significant whether considering pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 66 and 67).Mean CPUJE for fish eggs, all events combined, was greater at the discharge site than at either control (Table 68). However, neither number of fish egg taxa nor CPUE differed significantly among study sites during pre-uprate, post-uprate, summer, or winter sampling periods, or when all events were combined (Table 66). The only within-area difference for fish egg CPUE between pre- and post-uprate sampling periods was found at Control SL3, where significantly higher numbers were collected prior to the uprate (Table 67).A relatively large number of CRI decapod crustacean larvae were captured during plankton collections, with five taxa comprising over 78% of the crustaceans captured:
two mole crab taxa (Albunea sp. and Emerita talpoida), stone crabs (Menippe mercenaria), blue crabs (Callinectes sapidus), and different life stages of unidentified swimming crabs (Callinecles spp; Table 61).The mean CPUE for each CRI crustacean taxa captured by plankton nets is presented in Table 63. For all taxa combined, greater numbers were captured at the discharge site than at either control during both pre- and post-uprate summer sampling, as well as during pre-uprate winter sampling (Table 69). However, SL2 was intermediate to the two controls during post-uprate winter sampling.With one exception, no statistically significant differences were detected in the number of CRI crustacean larval taxa or corresponding CPUE either among or within study sites during any sampling period (Table 66 and 67). That exception occurred when the ANOVA indicated a significant difference among sites during summer sampling events. However, neither the ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 20 FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY Multiple Comparisons of Mean Ranks Post-hoc Test nor the Mann-Whitney U Test was able to determine which sites were significantly different from one another (Table 66).Nearshore Hardbottom Utilization by Sea Turtles The mean number of green turtle sightings was consistently higher at the discharge site than at either control during both pre- and post-uprate sampling periods (Table 70). When data from all pre- and post-uprate events were combined, the average number of green turtle sightings per one-kilometer-long transect ranged from 0.03 at Control SL3 to 2.32 at SL2.Statistical comparisons indicated the mean numbers of green turtle sightings at both the discharge site and Control SLI were significantly higher than Control SL3 during post-uprate, summer, and winter sampling periods and when all events were combined (Table 71). During pre-uprate monitoring, the mean number of green turtle sightings at SL2 was significantly higher than at either control. However, mean numbers of green turtle sightings did not differ significantly between pre- and post-uprate sampling periods within any study site (Table 72).DISCUSSION The purpose of Biological POS baseline monitoring was to establish background conditions against which to assess the effects of the St. Lucie Plant EPU. Monitoring was not intended to determine the overall effect of plant operations, as previous 316(a) studies demonstrated that thermal effluents from the St. Lucie Plant were not jeopardizing the protection and propagation of a balanced, indigenous population of fish, shellfish, and wildlife in receiving waters of the Atlantic Ocean (ABI, 1979). Rather, the Biological POS was intended solely to assess the effects of a minor elevation in discharge water temperatures resulting from the Units 1 and 2 EPU.Collectively, data collected during the Biological POS indicate a diverse assemblage of fish and shellfish 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.
Water quality within the study area is naturally affected by a number of variables including proximity to inlets, currents, tides, prevailing weather conditions, and occasional upwelling events. Given the high degree of spatial and temporal variability within this dynamic system, it would be virtually impossible to isolate natural variability in water quality from changes resulting from the EPU based on the infrequent data collected during this study.There were no statistically significant differences among the three study sites in the number of fish taxa, RIS taxa, or CRI invertebrate taxa collected by trawl either before or after the uprate.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 21 FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY There were no statistically significant differences among sites before the uprate with respect to CPUE for fish (all taxa combined), RIS (all taxa combined), individual RIS taxa, or CRI invertebrates.
Following the uprate, the discharge site had significantly lower fish CPUE and RIS CPUE than the northern control, but it did not differ significantly from the southern control.There were no statistically significant differences in mean RIS fish biomass among any of the three study sites prior to or following the uprate. Finally, none of the biological variables analyzed from trawl sampling at the discharge site differed significantly between pre- and post-uprate sampling periods. Based on these results, there is no indication that the uprate affected the benthic fish, RIS, or CRI invertebrate communities in the vicinity of the St. Lucie Plant.With respect to gill net sampling, there were no statistically significant differences in the number of fish taxa or RIS taxa among study sites either prior to or following the uprate. The mean CPUE for fish (all species combined) and RIS captured by gill net were not significantly different among study sites pre- or post-uprate, nor were there any statistically significant differences among study sites in the mean CPUE for individual RIS taxa. There were no statistically significant differences in mean RIS biomass among study sites either before or after the uprate. Finally, none of the biological variables analyzed from gill net sampling at the discharge site differed significantly between pre- and post-uprate sampling periods. Thus, as with the analysis of trawl data, there is no indication of an uprate effect on water column fish assemblages in the vicinity of the St. Lucie Plant. Too few CRI invertebrates were collected by gill net for any meaningful comparisons.
There were no statistically significant differences in numbers of fish or RIS taxa collected by beach seine among study sites before or after the uprate. Furthernmre, differences in the mean numbers of fish (all species combined), RIS (all species combined), and individual RIS taxa collected by beach seine did not differ significantly among study sites prior to or after the uprate, regardless of whether scaled sardines, the numerically dominant taxa, were included or excluded from the analysis.
Similar results were obtained when RIS biomass was statistically compared among study sites. None of the biological variables analyzed from beach seine data collected at the discharge site differed significantly between pre- and post-uprate sampling periods.Collectively these results give no indication of an uprate affect on surf zone fish in the vicinity of the St. Lucie Plant. Too few specimens of CRI invertebrates were collected by beach seine for any meaningful comparisons.
None of the differences among study sites 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 statistically significant, either before or after the uprate. Nor were there any significant differences in these variables between pre- and post-uprate sampling periods at the discharge site. These results provide no indication of an uprate effect on planktonic stages of fish and CRI invertebrate larvae in the vicinity of the St. Lucie Plant.ECOLOGICAL ASSOCIATES, INC., JENSEN BEACH, FLORIDA 22 FINAL REPORT, ST. LUCIE PLANT EPU BIOLOGICAL PLAN OF STUDY 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 both control sites during pre-uprate sampling, but only significantly different from the south control during post-uprate events.This change in the relationship among areas appeared to be due to slight increases in the number of turtles sighted at the north control and a small decrease at the discharge site following the uprate. However, none of these changes differed significantly between pre- and post-uprate events within any of the three study sties. These results indicate that there is no discernable uprate effect on small green sea turtles utilizing nearshore hardbottom habitat in the vicinity of the St. Lucie Plant.It should be emphasized that the number of individuals and taxonomic composition of faunal communities sampled, regardless of method, varied greatly over time as evidenced by high standard deviations about the means. Consequently, large differences in the absolute numeric means were often found not to be significantly different.
Even with best efforts to reduce variation by removing outlier catches and segregating results by season, very few significant differences were detected, either within or among study sites. Similar to the results of the 316(a)monitoring effort at the St. Lucie Plant in the 1970's (ABI, 1979), data collected during the current Biological POS provide no evidence that the recent plant uprate has affected the abundance or composition of faunal communities in the vicinity of the plant. Based on the huge capacity of the receiving water body (Atlantic Ocean) to dissipate heat, the effectiveness of the offshore discharge pipes in diffusing heated cooling water, the limited spatial area historically affected by thermal discharges, and the small change in discharge temperatures resulting from the uprate, the absence of any detectable EPU effects on faunal communities is not unexpected.
