Biological Assessment on the Potential Effects of a Proposed Turkey Point Nuclear Generating Unit Nos. 3 and 4 License Amendment on the American Crocodile 1.0 Introduction This biological assessment has been prepared to support the U.S. Nuclear Regulatory Commission (NRC)s review of Florida Power & Light Co. (FPL)s license amendment request (LAR) dated July 10, 2014, and to comply with the provisions of section 7 of the Endangered Species Act of 1973, as amended (ESA). This biological assessment examines the potential impacts of the Turkey Point Nuclear Generating Unit Nos. 3 and 4 (Turkey Point) on the American crocodile (Crocodylus acutus) under the proposed license amendment conditions.

NRC has been in coordination with U.S. Fish Wildlife Service (FWS) staff at the Vero Beach South Florida Ecological Services Office since regarding the proposed license amendment. Additionally, the NRC and U.S. Fish and Wildlife Service (FWS) have previously consulted under Section 7 of the ESA for Turkey Point on a number of occasions. Section 4.0 contains a brief history of section 7 consultations between the FWS and NRC.

2.0 Description of the Proposed Action 2.1 Proposed Action The proposed action is NRCs decision whether to approve FPLs request for an amendment to the Turkey Point Technical Specifications contained in Appendix A of Renewed Facility Operating Licenses DPR-31 (Unit 3) and DPR-41 (Unit 4). The proposed amendment would revise the Turkey Point ultimate heat sink (UHS) thermal limit from 100°F to 104°F. FPL submitted the LAR on July 10, 2014, and supplemented its request by letters dated July 17, July 22, and July 24, 2014 (FPL 2014a, 2014b, 2014c, 2014d). In its July 17, 2014, letter, the licensee requested the NRC to process the LAR expediently (FPL 2014b). If approved, the LAR would be effective from the date of NRC approval through the expiration dates of the renewed operating licenses.

The Turkey Point site includes two nuclear units (Units 3 and 4) and three fossil-fueled units (Units 1, 2, and 5). Units 1-4 use the same closed cooling canal system (CCS) to support operation; Unit 5 draws from the Floridan Aquifer for cooling and does not use the CCS. For the nuclear units, the CCS provides the coolant for the Circulating Water System (CWS) and serves as the UHS for the Intake Cooling Water System (ICWS).

The CWS provides cooling water to the main plant condensers, and the ICWS removes heat loads from the Component Cooling Water System (CCWS) during normal and accident conditions to support both reactor and containment heat removal requirements as well as spent fuel cooling requirements. The proposed amendment would allow the CCS (UHS) temperature to reach 104°F as measured at a the ICWS piping going to the inlet of the CCW heat exchanges at the north end of the CCS.

3.0 Proposed Action Area: Turkey Point Cooling Canal System The Turkey Point site and CCS have previously been described in the NRCs final supplemental environmental impact statement (SEIS) for Turkey Point license renewal (NRC 2002), the FWSs 2006 biological opinion for continued operation of Turkey Point

(FWS 2006a), and the NRCs 2011 biological assessment for the Turkey Point extended power uprate (EPU) (NRC 2011a). This section focuses on the changes that have taken place within the system that have prompted FPLs LAR to increase the UHS temperature limit. Anticipated future changes that would result from the proposed action or other actions taking place on the Turkey Point site are also discussed.

In June 2014, CCS temperatures approached the 100°F Technical Specification limit (e.g., 99.612°F and 99.713°F on June 25 and 29, 2014, respectively) (FPL 2014b). FPL (2014a, 2014e) believes that the recent higher trending temperatures are the result of a combination of factors within the CCS that include (1) high blue green algae concentrations, (2) low water levels associated with lower than average rainfall, and (3) sediment buildup. These factors are described below. Additionally, FPL has received approvals to temporarily withdraw water from the Floridan and Biscayne Aquifers, and approval to withdraw additional water from the Floridan Aquifer is likely forthcoming.

Because the aquifer withdrawals represent a change to the CCS not reflected in previous documents, they are also briefly described below.

Algae In 2011, FPL began to notice increased blue green algae concentrations in the CCS.

The concentrations have steadily increased since that time. FPL has performed engineering and environmental analyses and believes that the presence of higher than normal CCS algae concentrations may be diminishing the CCSs heat transfer capabilities. FPL developed a plan to gradually reduce algae concentrations through controlled chemical treatment of the CCS over the course of several weeks.

On June 18, 2014, FPL (2014h) submitted a request to the Florida Department of Environmental Protection (FDEP) to approve the use of copper sulfate, hydrogen peroxide, and a bio-stimulant to treat the algae. On June 27, 2014, the FDEP (2014) approved FPLs treatment plan for a 90-day trial period. The FDEP requested that during the 90-day treatment period, FPL monitor for total recoverable copper and dissolved oxygen and submit its results to the FDEP. The FDEP also recommended that FPL coordinate with the Florida Fish and Wildlife Conservation Commission (FWC) due to the presence of crocodiles in the cooling system. The FWC (2014) provided its comments on FPLs treatment plan in a letter dated July 1, 2014. Appendix A contains the letters referenced in this paragraph, which provide additional information on the algal treatment plan, timeline, and anticipated effects. FPL also developed a Water Quality Monitoring Plan for the chemical treatments, and this plan is also enclosed in Appendix A.

Low CCS Water Levels FPL (2014e) believes that low rainfall is contributing to higher than average CCS temperatures because the CCS partially relies on rainfall to recharge evaporative loss.

FPL data from a meteorological station in the middle of the CCS indicate that the site has experienced significant lower than average rainfall in 2013 and 2014. Rainfall for the years 2011 through the present are as follows.

Year Rainfall (in.)

2011 52.18 2012 74.25

Year Rainfall (in.)

2013 19.65 2014 (to date) 4.04 The lower rainfall has resulted in a corresponding decrease in CCS water levels.

CCS Elevation Year (ft, in NAVD88) 2012 -0.47 2013 -0.65 2014 (to date) -0.88 Sediment Buildup In addition to rainfall, groundwater exchange supplements CCS evaporative loss. FPL (2014e) has indicated that sediment buildup may be affecting this exchange. The company is evaluating longer term solutions to improve the conditions of the CCS, which may include measures to increase canal aeration and to de-muck the canal bottom (FPL 2014f).

Aquifer Withdrawals The CCS is situated above two aquifers: the shallower saltwater Biscayne Aquifer and the deeper brackish Floridan Aquifer. A confining layer separates the two aquifers from one another. Turkey Point, Unit 5, uses the Floridan Aquifer for cooling water. The South Florida Water Management District (SFWMD) granted FPL approval to withdraw a portion (approximately 5 million gallons per day [MGD]) of the Unit 5 withdrawal allowance for use in the CCS. FPL began pumping Floridan Aquifer water into the CCS in early July. FPL has also received temporary approval to withdraw 30 MGD from the Biscayne Aquifer, though FPL has not yet used this allowance. (FPL 2014f, 2014g)

FPL (2014f) also anticipates the FDEP to issue an Administrative Order requiring FPL to install up to six new wells that will pump approximately 14 MGD of water from the Floridan Aquifer into the CCS. Modeling performed by FPL consultants and the SFWMD indicates that in approximately two years, the withdrawals would reduce the salinity of the CCS to the equivalent of Biscayne Bay (about 34 parts per thousand [ppt]). Such withdrawals could also help moderate water temperatures.

4.0 Section 7 Consultation History 4.1 Informal Consultation for License Renewal NRC first initiated section 7 consultation with FWS regarding Turkey Point in 2001 as part of reviewing the Turkey Point license renewal application. During this consultation, NRC staff considered the potential adverse effects on 23 Federally listed species in its biological assessment (NRC 2001). In this 2001 biological assessment, the NRC concluded that license renewal would either have no effect or may affect, but would not be likely to adversely affect the 23 listed species. In December 2001, the FWS (2001) determined that the proposed license renewal would not adversely affect any listed species.

4.2 Formal Consultation Following Vehicle Collision In 2006, the NRC (2006) requested initiation of formal consultation for ongoing operation of Turkey Point after a juvenile American crocodile was hit by a vehicle on the Turkey Point site. The American crocodile was the only species considered during this consultation, and as a result of the consultation, the FWS (2006a) issued a biological opinion in May 2006. FWS (2006b) subsequently modified the biological opinion in August 2006. The 2006 biological opinion for the American crocodile remains in effect today.

4.3 Informal Consultation for Extended Power Uprate In 2011, following receipt of an LAR for an EPU at Turkey Point, the NRC (2011a) prepared a biological assessment (NRC 2011a) and requested initiation of consultation in a September 2011 letter (NRC 2011b). The biological assessment considers the American crocodile, its critical habitat, and 30 additional species that occur in Miami-Dade county. The FWS (2011) concurred with the NRCs biological assessment and concluded consultation in October 2011.

5.0 Federally Listed Species Considered This biological assessment considers the American crocodile because the proposed license amendment has the potential to affect only this species. The description, distribution, and habitat of the American crocodile have been previously documented in the NRCs 2001 biological assessment, the FWSs 2006 biological opinion, and the NRCs 2011 biological assessment.

FPLs annual crocodile monitoring reports for 2009 through 2013 associated with the EPU are attached as Appendix B and provide additional information on the crocodiles that inhabit the Turkey Point site.

The FWS has designated the majority of the Turkey Point site, including the CCS, as American crocodile critical habitat. The NRCs 2011 biological assessment describes the critical habitat in detail.

6.0 Proposed Action Effects Analysis 6.1 Direct Effects This section considers the potential effects of the proposed LAR to increase the UHS temperature limit from 100°F to 104°F. The proposed action would not directly increase the temperature; it would only increase the allowable temperature at the Technical Specification monitoring station at the north end of the CCS. Under the proposed action, temperatures between 100°F and 104°F would likely be experienced for only short durations during periods of peak summer air temperatures and low rainfall and may not be experienced at all depending on site and weather conditions. Such temperature increases would also increase CCS water evaporation rates and cause higher salinity levels. This effect would also be temporary and short in duration because salinity would again decrease upon freshwater recharge of the system through rainfall, stormwater runoff, and groundwater exchange.

The NRC identified three potential direct effects associated with the proposed action:

(1) reduced hatchling survival, (2) changes in crocodile growth rates, and (3) reduced habitat availability. Each of these potential effects are considered below. The potential

for adverse modification to designated critical habitat is considered together with reduced habitat availability.

Reduced Hatchling Survival Increased CCS water temperatures and resulting higher salinity levels could reduce hatchling survival because hatchlings are more limited in their ability to regulate their body temperature and to excrete salt than adult crocodiles. However, crocodiles respond to high water temperatures by moving into lower temperature areas within or outside of the cooling canal system. The Turkey Point site provides crocodiles access to several sources of non-CSS water, including the sites interceptor ditch, freshwater ponds that collect rainwater on the CCSs berms, and adjacent freshwater wetlands. Following the 2011 section 7 consultation for the EPU, FPL excavated three additional freshwater ponds on existing CCS berms in the southwest portion of the system to provide additional source of freshwater for crocodiles. Crocodiles also have access to the adjacent Card Sound and Biscayne Bay. Because hatchlings are mobile, the NRC staff expects that all of these water sources would be available to hatchlings.

FPLs annual crocodile monitoring reports associated with the EPU (enclosed as Appendix B) do not indicate that hatchling survival has changed as a result of the increased temperatures and salinity experienced in the CCS following implementation of the EPU. FPL (2014e) indicates that no changes in behavior have been identified during daily field observations under the recent high temperature conditions. The NRC staff believes that although the proposed action may affect hatchlings, such effects would never reach the scale of a take. Given the anticipated temporary and short duration of temperature increases between 100°F and 104°F and associated salinity increases, such effects likely could not be meaningfully measured, detected, or evaluated.

Hatchlings would continue to have access to a variety of water sources under the proposed action, which would mitigate any effects resulting from changes in the CCS.

Changes in Crocodile Growth Rates In the 2013 annual crocodile monitoring report, Mazzotti et al. (2013) found that crocodile growth (as change in total length) was affected by air and water temperatures.

Salinity was not found to affect growth, and growth (as change in mass) was not predicted by air temperatures, water temperatures, or salinity. Based on this information, temporary increases in CCS temperatures could affect crocodile growth rates. However, because both air and water temperatures play a role in crocodile growth, and the two factors would occur concurrently (i.e., as air temperatures rise, the CCS temperatures would also rise), the NRC staff does not believe that the proposed action would result in measurable effects that could be directly attributed to proposed action. Additionally, temperature increases would occur for only short durations, and crocodiles are mobile and would be able to avoid areas of higher CCS temperatures during these periods of time by moving to a different portion of the CCS or to another nearby body of water.

Reduced Habitat Availability Increased CCS water temperatures and resulting higher salinity levels could conceivably reduce the amount of habitat suitable for crocodiles in the CCS for short durations during periods of peak summer air temperatures and low rainfall. Such effects may be observed as changes in spatial distribution of individuals, increased competition for resources between individuals, or a decrease in the number of individuals that the Turkey Point site could support (reduced carrying capacity). Because the CCS is within designated critical habitat, adverse modification may also result if any of these effects are experienced.

Crocodiles within areas of unsuitable water temperatures may relocate to areas of CCS with more favorable temperatures. Kernal density estimation (KDE) maps of crocodile locations within the CCS during spotlight surveys throughout the year indicate that crocodiles tend to congregate in the southwest corner of the CCS during the summer.

These maps are included in the annual crocodile monitoring reports enclosed in Appendix B. Crocodiles would regain any temporary decreases in available suitable habitat once air and CCS temperatures drop. As previously mentioned, crocodiles have access to several other sources of water on and near the Turkey Point site. Thus, the NRC staff does not believe that any temporary reductions in suitable habitat experienced as a result of the proposed action would result in measurable changes in spatial distribution of individuals. FPL (2014f) indicated that despite the recent high temperatures in the CCS, crocodiles are exhibiting their normal distribution patterns for this time of the year during daily field observations.

Crocodiles maintain well-defined social hierarchies based on access to resources such as preferred temperature regimes. Thus, animals lower in social hierarchy could be displaced from the CCS during periods of higher CCS temperatures. However, because such displacement would likely be temporary and because crocodiles are mobile and could move to other waterbodies on and near the Turkey Point site, the NRC does not believe that the proposed action would increase competition for resources between individuals in a manner that could be meaningfully measured, detected, or evaluated.

Decreased carrying capacity would be expected to result if the proposed action permanently reduced or altered the available water resources on the Turkey Point site.

However, because periods of higher temperatures would be temporary and because the crocodiles have access to non-CCS water and habitat both on and off the site, the proposed action is unlikely to affect the carrying capacity of the site. Additionally, because the crocodile population continues to grow, there is no indication that the sites population is at or near carrying capacity, although such an effect could not be meaningfully measured or detected at this time.

Regarding whether temporary reductions in suitable habitat would constitute adverse modification to critical habitat, the FWS determines destruction or adverse modification to designated critical habitat on the basis of whether, with implementation of the proposed Federal action, the affected critical habitat would continue to serve its intended conservation role for the species and to support the species life-history needs (79 FR 39756). The proposed action would not affect the Turkey Point sites ability to support the population of crocodiles that currently inhabit the site, and the annual monitoring reports indicate that the population continues to thrive despite the unusually hot and hypersaline conditions of the CCS. Thus, the NRC staff does not believe that the proposed action would result in adverse modification to the designated critical habitat on the site.

6.2 Indirect Effects The NRC did not identify any indirect effects associated with the proposed action.

6.3 Interrelated and Interdependent Effects The proposed action is separate from FPLs chemical treatment plan to reduce CCS algal concentrations because the FDEP, and not the NRC, has the authority to approve such treatments. However, the NRC considers this action to be interdependent to the proposed action because it has no independent utility apart from continued operation of

Turkey Point. Accordingly, the NRC briefly considers the effects of CCS chemical treatment on crocodiles in this section. The NRC also considers the aquifer additions to the CCS to be an interdependent action, and the effects of this action are discussed below, as well.

Effects of CCS Chemical Treatments Documents related to FPLs chemical treatment plan to reduce CCS algae concentrations are enclosed as Appendix A, and these documents provide details on the specific concentrations, duration, and application of copper sulfate, hydrogen peroxide, and bio-stimulant. The FDEP has limited the treatment to 90 days, and the FWC (2014) did not have any concerns regarding effects to crocodiles as a result of the treatment.

FPL will continue its regular crocodile monitoring during this time and would report any sign of impacts related to the treatment to the NRC and FWS. Since initial treatment, which began on July 2, 2014, FPL (2014f) has not observed any behavioral or distributional changes or any other noticeable differences that would indicate effects to crocodiles resulting from the chemical treatments.

Effects of Aquifer Withdrawals The current and anticipated future aquifer withdrawals would result in beneficial effects to crocodiles inhabiting the Turkey Point site. FPL anticipates that the withdrawals will reduce the salinity of the CCS to about 34 ppt and could also help moderate CCS temperatures over the long term. Both of these effects would create favorable conditions for the crocodile.

6.4 Cumulative Effects The NRC did not identify any cumulative effects associated with the proposed action.

7.0 Conclusion and Determination of Effects American Crocodile The NRC staff concludes that the proposed action may affect, but is not likely to adversely affect the American crocodile. The increase in the allowable UHS (CCS) temperature from 100°F to 104°F under the proposed action could result in insignificant or discountable effects to hatchling survival, crocodile growth, and effects related to reduced habitat availability. Such effects would be experienced for only short durations during periods of peak summer temperatures and may not be experienced at all depending on site and weather conditions. The crocodiles on the Turkey Point site have already adapted to the sites conditions, which include temperatures and salinities above the species typical preferences. Crocodiles may also adapt to conditions under the proposed action without measurable or detectable impacts. The current and future aquifer withdrawals would result in beneficial impacts to the species and could negate any impacts of the proposed action once the withdrawals are fully implemented.

As a result of the EPU, which was fully implemented in 2013, the FDEPs amended Site Certification continues to require FPL to monitor crocodiles and prepare annual reports that address any observed impacts to crocodiles, including changes in growth, survival, abundance, and spatial distribution. Such monitoring would continue under the proposed action and would provide valuable information to determine if the UHS LAR results in unanticipated adverse impacts in the future.

American Crocodile Critical Habitat The NRC staff concludes that the proposed action would have no effect on designated critical habitat because the CCS would continue to serve its intended conservation role for the species and would continue to support the species life-history needs. The annual monitoring reports indicate that the Turkey Point crocodile population continues to thrive despite the unusually hot and hypersaline conditions of the CCS. Future monitoring reports would document any unanticipated adverse impacts that result from the UHS LAR.

Appendix A Documents Related to the Florida Department of Environmental Protections Approval of Chemical Treatment to Control Blue Green Algae in the Cooling Canal System

June 18, 2014 L-2014-191 Mr. Marc Harris Industrial Wastewater Section Florida Department of Environmental Protection 2600 Blair Stone Road Tallahassee, Florida 32399-2400 RE: FPL-Turkey Point Units 3 and 4 Wastewater Permit FL0001562 Request for Approval for the Use of Copper Sulfate, Hydrogen Peroxide and a Bio-Stimulant in the Treatment and Control of Blue Green Algae in the Cooling Canal System (CCS)

Florida Power and Light Company (FPL) is herein requesting Florida Department of Environmental Protection (FDEP) to approve the short term use of copper sulfate, hydrogen peroxide, and a bio-stimulate as part of a mitigating strategy for reducing or eliminating Turkey Point Cooling Canal algae growth. We recommend that this action be approved as construction, replacement or repair of components of an industrial site or plant, pursuant to Rule 62-620.200(26)(b), Florida Administrative Code.

Both Turkey Point Nuclear Operating Units are currently experiencing a high incidence of condenser tube and auxiliary heat exchanger tube biofouling, reduced heat transfer (a viscosity affect), and higher than normal canal temperatures. This is causing MWe reductions, more frequent heat exchanger cleanings and reduced margin to our design conditions. In addition, the intake weir baskets and screens are experiencing a higher than normal loading due to algae buildup. These declining changes in equipment efficiencies and greater than expected maintenance requirements have been recently noted in the power plant operating data, and were initially noticed during the fourth quarter of 2013. The water quality in the cooling canal has appeared to change since late 2013, and through laboratory testing, FPL has determined that the change is attributed to a high concentration of blue-green algae (cyano bacteria) in the water column.

At this time, the factors contributing to the increased algae growth are being evaluated by FPL and our independent contractor.

The Site has formed a team of engineers and environmental specialists to evaluate the water quality concerns and recommend a course of action to improve the canal water quality and to effect an improvement in the plants operations and maintenance programs. This team has been supplemented with engineers from Enercon Services, Inc. (ENERCON). ENERCON reviewed a number of potential options to control the algae in the CCS, and they have recommended the chemical treatment discussed within this letter. The algae treatment is anticipated to continue for approximately seventy five to ninety days.

While immediate eradication of the algae is possible and highly desirable from a plant operation perspective, there are biological impacts from a sudden algae die off and decay that must be mitigated and/or avoided. An immediate algae kill would likely cause a spike in biological oxygen demand (BOD), as well as, a release of toxins that could result in a fish kill and/or harm Florida Power & Light Company 9760 SW 344 St Homestead, FL 33035 A-2

L-2014-191 Page 2 of 4 the crocodiles. While a gradual reduction in algae concentration is preferred due to the concerns mentioned above, FPL has an urgent need to control the algae prior to the peak heat loading conditions anticipated in the summer months. To balance the two, a near-term corrective action has been identified to reduce the algae population in the near term while a more long-term solution is identified, developed and implemented.

The recommended approach is to apply copper sulfate, a bio-stimulant and hydrogen peroxide to the CCS in a staged treatment plan. This recommended approach is outlined below.

Chemical Treatment Approach Light applications of copper sulfate and a bio-stimulant will work synergistically to reduce the algae population. The bio-stimulant will enhance the respiration rate of the existing bacteria to initiate degradation of accumulated sludge materials in the bottom of the CCS. An initial shock dosage of the bio-stimulant will significantly aid in "jump starting" the degradation process. To prevent the dead algae from causing water quality issues, as well as to facilitate the biological digestion of the sludge in the bottom of the CCS, the copper sulfate/bio-stimulant application will be preceded and followed by applications of hydrogen peroxide added directly into the CCS.

ENERCON recommends that the algae populations be reduced in stages throughout the CCS in an effort to prevent adverse impacts from a quick algae kill within the entire canal system. The CCS will be divided into either two or three zones (See Attachment 1). Zone one will be treated weekly with copper sulfate, bio-stimulator, and hydrogen peroxide. FPL will assess the effectiveness of treatment in Zone 1, and determine whether or not to also move treatment into Zones 2 and 3.

Temperature, total nitrogen, total phosphorus, and pH data will be monitored at one or more surface water monitoring locations within the canal, and the results will be reviewed weekly during the chemical treatment period. This initial weekly application will continue until such time as a long-term solution is implemented or weather conditions allow the curtailment of these efforts. When applied at label rates, copper sulfate is safe and not toxic to fish, crocodiles and other wildlife found in and around the CCS; however, to be conservative, ENERCON recommends applying copper sulfate below label rates to build in a safety buffer. provides the Material Safety Data Sheets for the three chemicals scheduled for use in the canal.

Chemical Information Copper sulfate: Copper sulfate is available in powder, crystal or liquid form, and must be dissolved in water before it is applied to the CCS. Plating or metal replacement issues are not anticipated from the copper sulfate on the heat exchange units. The copper sulfate will be applied at relatively low rates; therefore, the concentration of free copper will be limited in the CCS. The canal pH is slightly alkaline, approximately 8.5, which means that once applied, the free availability of copper is nearly nonexistent. As a result, the free copper will be attenuated to soil particles in the bottom of the CCS. The pH would have to drop below approximately 4.0 (which is unlikely), before the copper will go into solution and potentially impact the heat exchange units.

A-3

L-2014:.191 Page 3 of 4 Copper sulfate is widely used in the control of algae, and when used at manufacturer label recommended doses, it has been demonstrated to not harm aquatic animals. The U.S. EPA completed registration of copper sulfate as an algaecide in 2009 (Boone, et al., 2012).

Bio-stimulant: The bio-stimulant is a combination of bacteria, enzymes and polymers that increases microorganism activity and will accelerate the digestion of sludge in the bottom of the CCS. It is not expected that these organisms will have any adverse effects on the heat exchange units. As the sludge in the CCS is digested, the nutrient levels will be lowered which will reduce the algae population. An additional benefit is that the digestion of the organic material in the bottom of the CCS may increase the total volume of water, which may improve the CCS heat exchange properties.

Hydrogen peroxide: To mitigate the oxygen depleting effects of the copper sulfate and to facilitate the biological digestion of the sludge at the bottom of the CCS, hydrogen peroxide will be applied along with the copper sulfate.

Hydrogen peroxide is a standard oxidizer that is often used in the aquaculture industry as an oxidizer for fish populations. In simple terms, it is a water molecule with an extra loosely bonded oxygen atom attached, which will be released to the water column upon application.

The hydrogen peroxide will be applied in a liquid stream to maximize the amount of oxygen that is released and available to the organisms in the CCS. Because the hydrogen peroxide is applied directly to the canal water, the loosely bonded oxygen atom is expected to release quickly with no direct or indirect negative impacts to the heat exchange units.

The recommended application rates for each treatment option have not been finalized; however, approximate dosages are provided below for planning purposes. A summary of the recommended near-term option chemicals, application rate, and notes on corrosive potential to the plant equipment is provided in Table 1.

1.0 Background

The cooling canal system (CCS) at Turkey Point Nuclear Generating Facility (PTN) is not cooling efficiently due in part to excessive growth of blue-green algae (algae). The CCS is approximately 169 miles long with an approximate footprint of 5 miles by 5 miles and contains approximately 3.5 billion gallons of water during normal operations.

Enercon Services, Inc. (ENERCON) has prepared a treatment process to control the algae population in the CCS. This will be accomplished through the application of a copper sulfate product, hydrogen peroxide, and a bio-stimulant.

Part of the ENERCON process includes monitoring selected water quality parameters as a way to monitor the success of the chemical treatment and to monitor for any unexpected environmental impacts in the CCS.

2.0 Water Quality Monitoring Plan Water quality will be monitored on two sampling regimes simultaneously; a data set collected weekly, and a suite of data collected daily. A background set of data will be collected prior to the start of the chemical treatment.

The weekly data set will include the standard data collection at existing PTN surface water quality data collection points. The analysis will be in accordance with the Florida Department of Protection (FDEP) approval letter issued by the FDEP on June 27, 2014. The weekly laboratory water quality parameters are:

Total nitrogen

Total phosphorous

Total recoverable copper These data will be collected each Monday morning throughout the treatment effort. In addition, algae cell counts will be collected two times per week (Monday and Thursday) at three locations (TPSWCCS-1, TPSWCCS-4, and TPSWCCS-6) throughout the treatment effort.

The daily data set will include field parameters from four existing PTN surface water quality data collection points (TPSWCCS-1, TPSWCCS-3, TPSWCCS-4, and TPSWCCS-6; Figure 1), as well as one supplemental station located at the injection location. The following water quality data will be collected from these locations using an YSI Model 556 multi-meter or equivalent, provided by NEE, will be used to collect and monitor the following parameters:

Typically, the lowest dissolved oxygen (DO) readings would be expected shortly after daylight prior to the onset of daily photosynthesis. The highest DO reading would be expected to be in early to midafternoon.

In addition to the field data collected by ENERCON, NextEra Energy (NEE) will provide data from sampling points located in the CCS (Figure 1). This data will include:

Salinity

Specific conductance

Water temperature This data is collected at one-hour intervals and will be provided to ENERCON by NEE on a daily basis.

ANNUAL REPORT AMERICAN CROCODILE MONITORING PROGRAM FOR THE TURKEY POINT UPRATE Prepared by:

Frank J. Mazzotti, MichaelS. Cherkiss, and JeffreyS. Beauchamp Department of Wildlife Ecology and Conservation Fort Lauderdale Research and Education Center University of Florida 3205 College Avenue Fort Lauderdale, FL 33314 Prepared for:

Stacey Foster Florida Power and Light Company PO #4500473320 2009 B-4

Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development suppot1ing a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to listing the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980's to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:

13027).

The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps.

While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power and Light's Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).

Adult crocodiles were first observed at TP in1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al. 1995). Rice et al. (2009) reported that one thousand three hundred and tln*ee crocodile nests were located in the tln*ee nesting areas (776 in ENP, 195 at CLNWR and 776 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98% (N = 332) and the lowest annual variation (91-100 %) in success. In several years FPL is planning an uprate, which will increase temperatures and salinities within the cooling canal system, possibly having an effect on crocodile growth, survival, distribution, and abundance.

Project Objectives:

I. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.

2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.

Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.

2 B-5

Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events were organized to cover as much of the system as possible, while concentrating effort in areas where crocodiles were known to be present. Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL),

snout-vent length (SVL), total length (TL), tail girth (TG), mass, and when possible sex was determined. Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time.

Capture data is recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.

Task 2. Conduct 5potlight surveys to locate crocodiles.

To determine spatial distribution and encounter rate of crocodiles at TP, monthly spotlight surveys were conducted of the entire cooling canal system over 2-4 nights.

Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed once a month via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.

Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data are backed up on the PDA upon completion of each nightly survey. The PDA is then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.

Environmental Data Nineteen temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record temperature every 30 minutes were deployed throughout the TP cooling canal system (Figure I). Fifteen recorded water temperature and four air temperature. Dataloggers were downloaded monthly, on the same days as the spotlight surveys. Salinity (measured in parts per thousand) was measured at predetermined locations using a hand held refractometer once a month at the time of each survey (Figure I). Wind speed (measured with a Kestrel 2000), cloud cover, and moon phase were also recorded at the beginning of each survey.

Task 3. Pe1jorm data analysis 3

B-6

Analysis of growth and survival of crocodiles followed procedures used by Rice et al. (2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system monthly and regression was used to evaluate whether monthly surveys are required, or if surveys could be completed every other month without compromising the information being collected. Spatial distribution of crocodiles in relation to salinity and temperature was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.

Results Task I.

Two capture events were conducted at TP during 2009, the first in January and the second in May. One hundred twenty four crocodiles were captured, of which 8 were captured twice during the same capture event; duplicate data is not included in the table (Table I, Figure 2). Thirteen percent (15) were young of year, sixty-six percent (76) were juveniles (0.65 to< 1.5 m TL), sixteen percent (19) were subadults (1.5 to< 2.25 m TL),

and five percent (6) were adults(::>_ 2.25 m TL). In addition, there were 96 recaptures of 82 individual crocodiles, whose time between captures ranged from a few months to over 25 years. Growth was calculated for 70 of the 82 individuals (Table 2). Initial capture records for the remaining 12 were not available. Hatchling crocodiles accounted for 79%

(55) of original captures. Change in total length ranged from -0.02 to 0.28 em/day and change in mass from -8.66 to 25.58 g/day. Survival of hatchlings for TP during the first year was calculated from the existing database using direct enumeration with and without the two capture events from 2009 for the period of2002 through 2008 (Table 3) .

Hatchling first year survival with the capture events ranged from I% to 6%, higher than without the 2009 capture events.

Task 2.

Monthly spotlight surveys were performed at TP between I October 2008 and 30 September 2009. A total of 1309 observations of crocodiles were made (Table 4), of which size estimates were possible for 1124. Of those, 282 (25.1 %) were hatchlings, 369 (32.8 %) juveniles, 300 (26.7 %) subadults, and 173 (15.4 %) adults. In addition, 185 animals could not be placed in a qumter meter size class and were categorized as unknown (138), large (17), medium (13) and small (17).

Chi square analysis was significant for the difference in total number of crocodiles observed between sections of the cooling canal system for several of the months (Table 5). Regression analysis showed a decrease in the overall number of crocodiles/km in relation to increased mean monthly water temperature (Figure 3), with juveniles being the only size class to show an increase in observations with an increase in water temperature (Figure 4). Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year. For example, Figures 5-9 show a change in core area use during the breeding season. Finally, regression analysis showed no difference in the power of bimonthly and monthly surveys 4

B-7

to detect changes. Confidence intervals for 12 month, six month odd and six month even schedules overlapped between each scenario (Table 6).

Environmental Data Based on water temperatures recorded throughout the cooling canal system, we found temperature varies seasonally and spatially (Figure I 0) with warmer temperatures in the northern and eastern sections of the discharge canals. The number of temperature loggers used in 2009 allowed us to roughly describe the cooling canal system thermally, but were not adequate for a detailed model approach. Tlu*ough interpolation, we were able to determine 24 temperature loggers are required to adequately describe the system.

Conversely, monthly salinity measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatially (Figure II).

Summal'y and Recommendations In several years FPL is planning an uprate, which will increase temperatures and salinities within the cooling canal system, possibly having an effect on crocodile growth, survival, distribution, and abundance. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the uprate. In the past year, we found that crocodiles of all size classes are found throughout the system. There was a decrease in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with juveniles being the only size class to show an increase in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system monthly. Seventy-eight percent of crocodiles captured were previously marked and 80% were originally marked as hatchlings, providing valuable growth and survival information.

We recommend for year two to increase the number of temperature sensor loggers, in order to characterize the system thermally and enhance the ability to model habitat suitability for crocodiles using temperature, salinity and habitat. We will reduce spotlight surveys effort to every other month and increase captures by a third effort, to better quantify survival and growth of crocodiles.

I ntl'oduction The American crocodile (Crocodylus acutus) is a coastal crocodilinn that occurs primarily in extreme southern mninland Florida and northern Florida Keys (Kushlan and Mazzetti 1989, Mazzetti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Deach, Broward, Minmi**

Dade, and Monroe Counties, has been the primary cause of endnngerment for C. acutus (Mazzetti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to listing the Florida population of C. acutus ns endangered in 1975 (Federal Register 40:44151 ). However, in 2007, based on results of ongoing monitoring studies from the early 1980's to the present (Moler 1992, Brandt et al. 1995, Mazzotti et nl. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:

13027).

The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastnl species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging fmm fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to distmbed ot* matHtwde habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades

National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Company's Turkey Point Power Plant {TP) site (Thorbjarnarson 1989, Mazzetti et al. 2007).

Adult crocodiles were first observed at TP inl976. In 1978, nesting was discovered when hatchling crocodiles were observed nnd captured in the cooling canals (Brandt et al.

1995). Rice ct al. (2009) reported that one thousand three hundred and three crocodifc nests were located in the tlU"ee nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid thnt produce at least one hatchling) between 1978 and 2008 at 98 % (N =

332) and the lowest annual vmiation (91 -100 %) in success. FPL is platming an Uprate, which will slightly increase temperatures and salinities within the cooling canal system.

The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.

l,roject Objectives:

I. Determine growth and smvival of crocodiles at the Tmkey Point Power Plant site.

2. Determine spatial pattcm of crocodiles at TP in relation to temperature and salinity.

2 B-60

Methods Task 1. Conduct caplure surveys for growlh and survival of crocodiles.

Growth and smvival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Captme events were organized to cover as much of the system as possible, while concentrating effort in areas where crocodiles were known to be present.

Crocodiles were captmed using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captmed crocodiles, we measured head length (HL), snout~vent length (SVL), total length (TL), tail girth (TG), mass, and when possible sex was determined.

Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an rmimal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.

Task 2. Conduct spotlight surveys lo locate crocodiles.

To determine spatial distribt1tion and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-4 nights every other month.

Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (10) canal was smveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.

Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight smvcy data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.

Environmental Data Twenty-six temperature sensitive data loggers (Onset Tidbi'r'lil v2 Temp) set to record water temperatme every 30 minutes were deployed throughout the TP cooling canal system, and downloaded before each smvey (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figme 1). Wind speed (measured with a Kestrel2000),

cloud cover, and moon phase were also recorded at the beginning of each survey.

3 B-61

Task 3. Pelform data analysis Analysis of growth and survival of crocodiles followed proccdmes used by Rice et al.

(2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles in relation to salinity and temperature was assessed using a geographic information system in combination with logistic regression and Kcmel Density Area analysis.

Results Task 1.

Three capture events were conducted at TP during 20 l 0, the first in January second in May and third in November. One hundred eighty-six crocodiles were captured, of which 6 were captmed twice dming the same capture event; duplicate data is not included in the table (Table l, Pigure 2). Twenty-nine percent (53) were young of year, 47% (85) were juveniles (0.65 to < 1.5 m TL), 17% (30) were subadults ( 1.5 to < 2.25 m TL), and 7%

(12) were adults(~ 2.25 m TL). In addition, there were 150 rccaptmes, whose time between captmes ranged from a few months to over 26 years. Growth was calculated for l 04 for whom original capture information was available (Table 2). Change in total length ranged from 0.013 to 0.196 em/day and change in mass from -0.014 to 36.388 g/day. Smvival of hatchlings for TP was calculated from the existing database using direct enumeration with the capture events from 2009 and 201 0 for the period of 2002 tlU'ough 2009 (Table 3). Hatchling first six month survival ranged tl*om 1% to 7%.

Task 2.

Monthly spotlight smveys were performed at TP between 23 February 2010 and 9 December 2010. A total of 500 observations of crocodiles were made (Table 4), of which 418 were placed in a size class. Thirteen (3 %) were hatchlings, 216 (43 %)

juveniles, 116 (23 %) subadults, and 73 (15 %) adults, with the remaining 82 (16 %)

unknown.

Chi square analysis was significnnt for the difference in total number of crocodiles observed between sections of the cooling canal system for a couple of the months (Table 5). Regression analysis.showed an increase in the overall number of crocodiles/km in relation to increased menn monthly water temperature (Figme 3), with adults being the only size class to show a decrease in observations with an incrense in water temperalme (Figure 4). Kemal Density Area analysis of crocodile observations from spot! ight surveys resulted in a change of core area use throughout the year (Figures 5 - 10).

4 B-62

Environmental Data 13nsed on water temperatures recorded throughout the cooling canal system, we found temperature varies scnsonally nnd spntially (Figure 11) with wmmer temperatmes in the northern cmd eastern sections of the discharge cmwls. Conversely, monthly salinity measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatinlly (Figure 12).

SmnllliH'Y nnd Uccommendntions In seveml yenrs FPL is plmming an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may possibly have nn effect on crocodile growth, survival, distribution, and abundnnce. These systematic spotlight and capture surveys provide comprehensive bnseJine data on distribution, abundance, growth and smvival of American crocodiles at Tmkey Point prior to the Uprate. In the past year, we found thnt crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased menn monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system. One hundred and fifty crocodiles captmecl were previously mmkcd and 87 were originally mnrked as a hatchling, providing valuable gmwth and smvival information:

We recommend continuing to perform spotlight smveys every other month and to complete three captme events mumally to continue quantifying survival and growth of crocodiles.

Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to list the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980s to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Companys Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).
Adult crocodiles were first observed at TP in1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al.
1995). Rice et al. (2009) reported that one thousand three hundred and three crocodile nests were located in the three nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98 % (N =
332) and the lowest annual variation (91-100 %) in success. FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. .
The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.
Project Objectives:
1. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.
2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.
2 B-101
Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.
Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events were organized to cover as much of the system as possible, while concentrating effort in areas where crocodiles were known to be present.
Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL), snout-vent length (SVL), total length (TL), tail girth (TG), mass, and when possible, sex was determined.
Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct spotlight surveys to locate crocodiles.
To determine spatial distribution and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-4 nights every other month.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Twenty-six temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record water temperature every 30 minutes were deployed throughout the TP cooling canal system, and downloaded before each survey (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figure 1). Wind speed (measured with a Kestrel 2000),
cloud cover, and moon phase were also recorded at the beginning of each survey.
3 B-102
Task 3. Perform data analysis Analysis of growth and survival of crocodiles followed procedures used by Rice et al.
(2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles in relation to salinity and temperature was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.
Results Task 1.
Three capture events were conducted at TP during 2011, the first in January, the second in May and the third in November. One hundred seventeen crocodiles were captured (Table 1, Figure 2). Seventeen percent (20) were young of year, 65% (76) were juveniles (0.65 to < 1.5 m TL), 14 % (16) were subadults (1.5 to < 2.25 m TL), and 4 % (5) were adults ( 2.25 m TL). In addition, there were 97 recaptures, whose time between captures ranged from 49 days to over 18 years. Growth was calculated for 90 for whom original capture information was available (Table 2). Change in total length ranged from
-0.028 to 0.2840 cm/day and change in mass from 0.1 to 20.408 g/day. Survival of hatchlings for TP was calculated from the existing database using direct enumeration with the capture events from 2010 and 2011 for the period of 2002 through 2010 (Table 3). Hatchling first six month survival ranged from 1% to 7%.
Task 2.
Spotlight surveys were performed at TP every other month between 07 February 2011 and 20 December 2011. A total of 747 observations of crocodiles were made (Table 4),
of which 520 were placed in a size class. Forty-nine (6.6 %) were hatchlings, 199 (26.6
%) juveniles, 206 (27.6 %) sub-adults, and 66 (8.8 %) adults, with the remaining 227 (30.4 %) unknown.
Chi square analysis was significant for the difference in total number of crocodiles observed between sections of the cooling canal system for a couple of the months (Table 5). Regression analysis showed an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature (Figure 3), with adults being the only size class to show a decrease in observations with an increase in water temperature (Figure 4). Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year (Figures 4 - 9).
Environmental Data Based on water temperatures recorded throughout the cooling canal system, we found temperature varies seasonally and spatially (Figure 10) with warmer temperatures in the northern and eastern sections of the discharge canals. Conversely, monthly salinity 4
B-103
measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatially (Figure 11).
Summary and Recommendations In several years, FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may possibly have an effect on crocodile growth, survival, distribution, and abundance. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the Uprate. In the past year, we found that crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system. One hundred and seventeen crocodiles were captured, of that 90 provided valuable growth and survival information.
We recommend continuing to perform spotlight surveys every other month and to complete three capture events annually to continue quantifying survival and growth of crocodiles.

Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to list the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980s to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Companys Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).
Adult crocodiles were first observed at TP in1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al.
1995). Rice et al. (2009) reported that one thousand three hundred and three crocodile nests were located in the three nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98 % (N =
332) and the lowest annual variation (91-100 %) in success. FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system.
The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.
Project Objectives:
1. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.
2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.
B-145
Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.
Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events in 2012 were organized to concentrate effort in areas where crocodiles were known to be numerous. Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL), snout-vent length (SVL), total length (TL),
tail girth (TG), mass, and when possible, sex was determined. Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct spotlight surveys to locate crocodiles.
To determine spatial distribution and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-3 nights every other month.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Twenty-six temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record water temperature every 30 minutes were deployed throughout the TP cooling canal system, and downloaded once a month (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figure 1). Wind speed (measured with a Kestrel 2000),
cloud cover, and moon phase were also recorded at the beginning of each survey.
B-146
Task 3. Perform data analysis.
Analysis of growth and survival of crocodiles followed procedures used by Rice et al.
(2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.
Results Task 1.
Three capture events were conducted at TP during 2012, the first in January, the second in April and the third in November. Ninety-eight crocodiles were captured (Table 1, Figure 2). Forty-two percent (41) were young of year, 44% (43) were juveniles (0.65 to <
1.5 m TL), 11 % (11) were subadults (1.5 to < 2.25 m TL), and 3 % (3) were adults (
2.25 m TL). In addition, there were 74 recaptures, whose time between captures ranged from 42 days to over 14 years. Growth was calculated for 67 for whom previous capture information was available (Table 2). Change in total length ranged from 0.02 to 0.22 cm/day and change in mass from -0.24 to 29.64 g/day. Survival of hatchlings for TP was calculated from the existing database using direct enumeration with the capture events from 2009 to 2012 for the period of 2002 through 2011 (Table 3). Hatchling first six month survival ranged from 1% to 9%.
Task 2.
Spotlight surveys were performed at TP every other month between 15 February 2012 and 18 December 2012. A total of 675 observations of crocodiles were made (Table 4),
of which 410 were placed in a size class. Thirty-two (4.7 %) were hatchlings, 135 (20.0
%) juveniles, 178 (26.4 %) sub-adults, and 65 (9.6 %) adults, with the remaining 265 (39.3 %) unknown.
Chi square analysis was significant for the difference in total number of crocodiles observed between sections of the cooling canal system for a couple of the months (Table 5). Regression analysis showed an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature (Figure 3).
Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year (Figures 4 - 9).
Environmental Data Based on water temperatures recorded throughout the cooling canal system, we found temperature varies seasonally and spatially (Figure 10) with warmer temperatures in the northern and eastern sections of the discharge canals. Conversely, bimonthly salinity B-147
measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatially (Figure 11).
Summary and Recommendations This 2012 monitoring report provides pre-uprate baseline data. In April 2013, FPL completed the uprate projects on Units 3 and 4. The uprate might slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may possibly have an effect on crocodile growth, survival, distribution, and abundance. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the Uprate. In the past year, we found that crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system.
Ninety-eight crocodiles were captured, of that 67 provided valuable growth and survival information.
We will analyze the data for the possibility of reducing spotlight survey efforts to quarterly and can suggest we do so, as long as there is no statistical loss in detectability from a reduced effort. We will complete three capture events annually to continue quantifying survival and growth of crocodiles.

Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to list the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980s to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Companys Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).
Adult crocodiles were first observed at TP in 1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al.
1995). Rice et al. (2009) reported that 1303 crocodile nests were located in the three nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008.
Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98% (N = 332) and the lowest annual variation (91-100 %) in success. FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.
Project Objectives:
1. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.
2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.

Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.
Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events in 2013 were organized to concentrate effort in areas where crocodiles were known to be numerous. Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL), snout-vent length (SVL), total length (TL),
tail girth (TG), mass, and when possible, sex was determined. Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data were entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct spotlight surveys to locate crocodiles.
To determine spatial distribution and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-3 nights every other month.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown based on total length.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Twenty-six temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record water temperature every 30 minutes were deployed throughout the TP cooling canal system, and downloaded once a month (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figure 1). Wind speed (measured with a Kestrel 2000),
cloud cover, and moon phase were also recorded at the beginning of each survey.
B-188
Task 3. Perform data analysis Analysis of growth and survival of crocodiles followed procedures used by Rice et al.
(2009). Analysis of growth (change in total length and mass) was performed on crocodiles captured between January 2009 and June 2013, as a part of this ongoing project and for any individual that had been previously captured and for whom initial data was available. A one-way analysis of variance (ANOVA) was calculated to detect a difference in growth rates as changes in total length and weight. A t-test was performed to detect differences in growth between male and female animals. Environmental conditions such as air temperature, water temperature, and salinity were used as predictors of growth rates. Regression analysis was run to assess hatchling survival between 2000 and 2012. A Chi Square analysis was also used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.
Results Task 1.
Three capture events were conducted at TP during 2013, the first in February, the second in June and the third in December. In addition several miscellaneous animals were handled by Mario Aldecoa this year and these data are included here. One hundred and two crocodiles were captured in the cooling canal system in 2013 (Table 1, Figure 2).
Forty-eight percent (49) were young of year, 40% (41) were juveniles (0.65 to < 1.5 m TL), 10 % (10) were subadults (1.5 to < 2.25 m TL), and 2 % (2) were adults ( 2.25 m TL).
Crocodile Growth As a part of this project, a total of 591 crocodile capture events occurred between 2009 and 2013 at Turkey Point. Of these events, 157 hatchlings, 320 juveniles, 88 sub-adults, and 26 adults were captured. A total of 298 crocodiles were recaptured for which we had initial capture data for and were used to calculate growth as changes in total length and weight over time. Hatchlings accounted for 84% of all initial captures, juveniles 13%,
sub-adults 3%, and a single adult was initially caught as an adult and recaptured during this study period (Table 2). Initial measurements of body size as total length and weight ranged from 21-65 cm and 36-900 g in hatchlings, juveniles ranged in size from 65-150 cm and 510-10000g, sub-adults ranged from 151-184 cm and 8700-18400 g, and the lone adult measured 272 cm and 63500 g (means, Table 2). Growth as changes in total length varied across size classes with a range of -0.003 to 0.284 cm/day in hatchlings, -0.006 to 0.083 cm/day in juveniles, 0.017 to 0.080 cm/day in sub-adults, and 0.022 cm/day in the lone adult recapture (Table 2, Figure 3). Changes in weight represent a wider range of growth from -0.183 to 49.372 g/day in hatchlings, -10.938 to 19.351 g/day in juveniles, 3.125 to 29.644 g/day in sub-adults, and 36.388 g/day in the adult recapture (Figure 4),
mean values are presented in Table 2.
B-189
A one-way analysis of variance (ANOVA) was calculated to detect a difference in growth rates as changes in total length and weight. Results illustrate that hatchlings experienced the greatest change in total length relative to all other size classes (F (3, 294) =
952.748, p < 0.001; Tables 2, 3), whereas sub-adults and the lone adult increased in weight significantly more so than hatchlings and juveniles combined (F (3, 294) =
1669.741, p < 0.001; Tables 2, 3). Crocodiles were recaptured anywhere between 3 days to 25 years and at an average of 3 years (Table 2), but there was no difference in the number of days in between capture across the size classes (Table 3). Crocodiles were also recaptured throughout Turkey Point, but a greater number of individuals were captured in Sections 4 and 5 relative to any other section of the cooling canal system (2 = 790.95, df
= 9, p< 0.001; Figure 2).
Of the 298 crocodiles, we recaptured 140 females, 111 males and 47 individuals of unknown sex (Table 4). For purposes of analyses, measurements of only males and females are discussed. At the time of first capture male crocodiles ranged in size from 23-156 cm total length and weighed 39-11000g, and female size ranged from 22-272 cm total length and 42-63500 g in weight (mean measures Table 4). Changes in total length of male crocodiles ranged from 0.000 to 0.196 cm/day, and female growth ranged from
-0.006 to 0.284 cm/day. Mean measures are presented in Table 3. Growth rate as body weight ranged in males from a decrease of weight of -3.600 g/day to an increase of 49.372 g/day, and female growth rate ranged from -10.938 to 36.388 g/day, mean growth rates are presented in Table 3. Independent samples t-test showed that males and females grew at similar growth rates measured as total length (t = 0.527, df = 249, p = 0.598) and there was a positive trend for females to have greater growth rates as weight (t = -1.775, df = 249, p = 0.077). There were slightly more days in between time of capture of females relative to males (1367 days vs. 1076 days) but this was not a significant difference (t = -1.538, df = 249, p = 0.115).
Environmental Conditions Growth was calculated in relation to environmental conditions of the habitat using a combination of data recorded by data loggers stationed throughout Turkey Point and from data collected at the start and end of each survey. Air temperature, water temperature, and salinity were measured throughout the study period. Using environmental conditions as predictors of crocodile growth rates, water temperature was a significant predictor of growth when measured as changes in total length ( = 0.389, p = 0.039), air temperature tended to be a predictor ( = -0.402, p = 0.068), but salinity did not predict growth ( = -
0.045, p = 0.291). The overall model fit for growth as changes in total length was R2 =
0.130, p = 0.236. Growth measured as changes in weight was not predicted by the measured environmental factors of temperature and salinity (R2 = 0.038, p = 0.820).
Water temperature varied seasonally throughout the canal system ranging from 19 to 41°C with peak temperatures occurring in August and lower temperatures registering in December (F = 51.340, df = 11, 304 P < 0.001; Figure 5). Water temperatures also varied significantly within the system, with higher temperatures ranging 27 to 41°C in Section 1 and lower temperatures ranging 19 to 39 °C in Section 6 (F = 19.011, df = 5, 310 P <
0.001; Figure 5). Water temperature significantly decreased as water flowed south (Figure 1 of cooling canal with sections and data loggers). Salinity remained greater than B-190
40 PST (mean 57.52 +/- 0.71 SE) defining Turkey Point as a hypersaline environment and was relatively uniform throughout the canal system (F = 0.113, df = 5, P = 0.989; Figure 6). The Interceptor Ditch (ID) had significantly lower salinity measurements (mean 3.15
+/- 0.766 SE; Figure 6) but is not incorporated in the cooling canal system. There were seasonal fluctuations of salinity across Turkey Point with October registering lower salinities and April registering higher salinities (F = 8.943, df = 5, P < 0.001; Figure 6);
however, mean salinity ranged from 52-63 PPT. Across the survey years, 2009 had the highest salinity records at 62.58 +/- 2.283 SE and the lowest salinity records were from 2012 at 52.78 +/- 1.372 SE.
Survival A total of 3931 hatchling crocodiles were marked from 2000 through 2012 at Turkey Point and of these 243 hatchlings have been recaptured (Table 5). Mean survival of hatchling crocodiles up until 2008 was 3% after which efforts were consolidated to increase systematic surveys. Survival rate has since increased to 11% (Table 5).
Regression analyses show that survey year effectively predicted hatchling survival rate (R2 = 0.764, p < 0.001; Figure 7) largely because the concerted effort ensured a greater numbers of crocodiles being recaptured.
Task 2.
Spotlight surveys were performed at TP every other month between 25 February 2013 and 9 December 2013. A total of 646 observations of crocodiles were made (Table 6), of which 433 individuals were placed in a size class. One-hundred crocodiles (15 %) were hatchlings, 119 (18 %) as juveniles, 139 (22 %) as sub-adults, and 75 (12 %) adults, with the remaining 213 (33 %) unknown.
Chi square analysis of total number of crocodiles observed between sections of the cooling canal system were significant for a couple of the months (Table 7). Regression analysis showed an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature (Figure 8), with subadults being the only size class to show no change in observations with an increase in water temperature. Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year (Figures 9 - 14).
Summary and Recommendations This 2013 monitoring report provides pre-uprate baseline data. In April 2013, FPL completed the uprate projects on Units 3 and 4. The uprate might slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to assess whether the uprate may have an effect on crocodile dynamics. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the Uprate.
B-191
In the past year, we found that crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with sub-adults being the only size class to show no change in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system.
We also analyzed and summarized growth rates (change in total length and mass) for all animals recaptured between 2008 and 2013 during this project. We found growth varied across size classes and that juvenile growth (change in total length) fell within the range previously reported by Mazzotti et al. 2007. We also found that while females and males grew at similar rates measured as total length, there was a positive trend for females to have greater growth rates measured as weight. Growth (change in total length) was affected by air and water temperature, whereas change in mass was not effected by any of the measured environmental parameters. We have also been able to measure hatchling survival through multiple capture events annually. Between the survival information, and the short and long term growth measures gained during this project, this is an excellent example of how long term monitoring programs are able to provide valuable information.
Between October of 2008 and December 2009, we performed monthly spotlight surveys for American crocodiles within the cooling canal system at Turkey Point. This effort was reduced to performing spotlight surveys every other month starting in February 2010 and was continued through December 2013. After completing analysis of the survey data collected over more than four years, between October 2008 and December 2012, we found that we could reduce survey efforts to quarterly without a statistically significant loss in our ability to detect changes in the spatial patterns of crocodiles within the cooling canal system. Therefore, we propose to change the frequency of spotlight surveys from every other month to quarterly beginning with surveys in 2014.

Subject:
Consultation Part 1 of 3 Attachments: NRC FWS Information 1.zip Hello Briana, I am having trouble sending you the documents they keep getting kicked back. I am breaking them out into several emails but please see the text response to your questions last night.
Effects to consider for LAR to increase of UHS to 104 degrees F:
Will the increased temperature or salinities resulting from the LAR reduce hatchling survival through increased stress or other means?
o As described during the Uprate section 7 consultation, Crocodiles respond to high water temperatures by moving into areas of lower temperature within or outside of the cooling canal system. Crocodiles are also able to survive the hypersaline environment by excreting salt through salt glands in their tongue, but require access to freshwater to persist. Sources of freshwater are known to occur at various localities within the cooling canal system (i.e.,
depressions and specially constructed ponds that collect rainwater runoff located on the canal systems berms), and outside of the cooling canal system within the adjacent interceptor ditch and freshwater marsh. Daily field observations have not identified a change in behavior. Data for the annual August surveys will be provided once the 2014 survey is complete.
Will the LAR affect the spatial distribution of crocodiles on the Turkey Point site?
o Based on current daily field observations the crocodiles are exhibiting their normal distribution patterns for this time of the year, concentrating in the south end of the CCS.
Will the LAR reduce habitat availability by decreasing the available suitable habitat in the CCS during the hottest times of the year?
o An increase in water temperature could conceivably reduce the amount of habitat suitable for crocodiles in the cooling canal system during the warmest part of the year.
As discussed, crocodiles within areas of unsuitable water temperatures may relocate to areas of cooling canal system with more favorable temperatures.
Will the LAR increase competition and result in individuals lower in social hierarchy to lose access to CCS waters?
o Response in the attached letter Will the LAR affect crocodile abundance/decrease the crocodile population carrying capacity of the Turkey Point site?
o Response in the attached letter Will the increased temperature affect crocodile growth rates?
o It is not expected to because the crocodiles can move in and out of the system. The canals typically experience the warmest temperatures in July and August.
Will the crocodiles be affected by chemical treatment of the algae?
o The chemical treatment of the algae is planned to be limited to 7-10 weeks. The limited duration of the treatment is not expected to affect the crocodiles.
Will the crocodiles be affected by the addition of aquifer water to the CCS?
o The water from the Floridan aquifer is specifically to reduce the salinity and temperature in the canals. The addition of this water is not expected to negatively impact the crocodiles as it will help to improve the water quality.

Electronic copies of the meeting handouts - in the attached letter Tables of temperature data depicted in handout graphs (if available). - in the attached letter Names of people that you mentioned that do the croc monitoring. You mentioned Mario and Joe. Can you provide last names and associations? I assume Frank is Frank Mazzotti?
o Mario Aldecoa is FPLs onsite biologist that oversees and conducts the nesting and hatchling surveys and ID canal surveys at Turkey Point, as well as participates in the UF IFAS Uprate monitoring. Joe Wasilewski is a wildlife biologist that specializes in working on the natural history of apex predators (crocodilians) within wetlands of south Florida. Previously, he was the onsite biologist at Turkey Point, and now he is a contractor that provides his expert opinion to FPL and assists FPL and UF IFAS with the capture surveys. Dr. Frank Mazzotti is the lead expert overseeing the American crocodile Uprate monitoring conducted by UF IFAS. He has over 25 years of experience researching and teaching issues relating to wildlife and their habitats in South Florida. A major focus of Dr. Mazzotti's research has been evaluating the effects of human activities on crocodilians and their habitats.
Rainfall numbers that Stacey mentioned at the beginning of the meeting (2011-present) and source of that info.
o In attached letter, Source is from the Annual Reports required as a part of the Pre- and Post-Uprate monitoring required by State agencies.
Summary/description of the current and planned aquifer pumping from the Biscayne and Floridian aquifers, including current and pending authorizations, current and future pumping rates, and description of purpose (i.e., to reduce the salinity of the CCS to ~34 ppt within 2 years and halt/reverse the line of salt water intrusion into the Biscayne Aquifer, if I understand correctly). A description of the Water Management Districts Administrative Order to create 6 new wells would be helpful as part of this.
o The Order is expected to come from the Department of Environmental Protection. The order will require FPL to install 6 new wells that will pump approximately 14 MGD of less saline water from the Floridan Aquifer. The Floridan Aquifer is a confined aquifer that is below the Biscayne Aquifer. The modeling performed by FPL consultant and South Florida Water Management District indicates it will take approximately 2 years to get the CCS back to salinity equivalent with Biscayne Bay.
Copies of all pre- and post-uprate crocodile monitoring reports. The only ones that I have a copy of are the two 2013 reports (Dec 30, 2013, report to FWS and July 3, 2014, report to SFWMD) and the May 14, 2014, progress report from Mazzotti. - Reports attached Thanks you, Stacy M.

PROBLEM STATEMENT:
The Turkey Point Cooling Canal System (CCS) is experiencing higher than normal temperature and salinity fluctuation than previously observed. Florida Power and Light Company (FPL) has requested a License Amendment Request (LAR) to increase the Ultimate Heat Sink (UHS) temperature limit from100 degrees Fahrenheit (°F) to 104 °F.
During the Uprating of the Unit 3, beginning in February 2012, flow through the canals was reduced. The Unit began to repower in September 2012, reaching full power in November 2012. In August 2012, FPL visually noticed that turbidity in the CCS was starting to increase. In November 2012, Unit 4 went offline and did not reach 100% power until June 2013. The canals during these outages were at a reduced flow for approximately 17 months. To understand the change in visibility, FPL took water samples and had them analyzed for algae content in August 2012. The results showed that the cell count were approximately 680,000 cells/ml. FPL analyzed for algae in September 2012, and the count had decreased by approximately 55%. In April 2014, FPL noticed the turbidity was increasing and again took samples to analyze for Algae and the cells counts. These results showed that the cell counts were back up. It was determined that the algal counts were affecting the ability of the CCS water to release heat and as a result was one of the factors causing the CCS temperature to increase. FPL requested approval from the Florida Department of Environmental Protection (FDEP) to use algaecide commonly used on ponds to treat the algae as a short term solution. The treatment has been effective in reducing the cell count. The treatment is expected to continue for 4 more weeks.
Both Units have been operating in the Uprated mode since June of 2013. The CCS relies on rainfall and ground water exchange to recharge the system. The CCS has a Meteorological Station in the middle of the system. The data from that system indicates much lower than average rainfall for 2013 and 2014. See rainfall table. This has also resulted in greater than normal temperature and salinity fluctuations in the system. Also, the connectivity with the groundwater appears to be hindered by potential sediment buildup. See water elevation table. (* Unit out for repair half of June 2013).

FPL has several stations that monitor temperature in the CCS on an hourly basis. Below is a time series temperature plot for 4 of those stations. The map identifies the station locations. Station CCS-3 is a station in the area that is utilized most by the crocodiles. The data indicates the temperature fluctuates throughout the year with temperature typically peaking in the month of July. The factor that restricts American crocodiles across their range is access to fresh water for their hatchlings to develop salt excreting glands. The Turkey Point Nuclear Power Plant Cooling Canal System is an ideal situation in order for the population to recruit more individuals. Within the CCS there are numerous fresh water and lower saline ponds where females place the hatchlings for the purpose of developing their salt excreting glands.

FPL is looking at interim and long-term solutions to decrease temperature and salinity in the CCS. Some of these solutions are aeration, sediment removal and introducing fresher Floridan Aquifer waster source to the CCS THREATENED AND ENDANGERED SPECIES EFFECTS:
The project site occurs within the geographic range of the threatened American crocodile (Crocodylus acutus) and is located within designated critical habitat for this species. Crocodiles are known to occur and nest within the 5,900-acre cooling canal system located immediately west of the Turkey Point Power plant. The cooling canal system is a closed system and does not discharge surface water to either Biscayne Bay or adjacent freshwater wetlands. The cooling canal system was originally filled with seawater from Biscayne Bay and is now augmented only by rainfall and freshwater pumped periodically from the Interceptor ditch (located along the western boundary of the cooling canal system) during the dry season. Heated water is currently discharged into the discharge canal located at the north end of the cooling canal system from nuclear power production units 3 and 4 and oil burning power production unit 1 located immediately north of the nuclear units. The heated water circulates to the southern end of the cooling canal system, then east and northward back to the Intake Canal for reuse in cooling units 1, 3, and 4.
The cooling canal system currently supports a large population of crocodiles because the berms constructed in association with the canal system provide high quality nesting habitat. However, the water in the cooling canal system provides a physically challenging environment for crocodiles. Due to the original use of sea water for cooling purposes, the ongoing deposition of heated water from power production, and the limited influx of fresh water, the water in cooling canal system is hypersaline (45 to 95 ppt). At times during the year, sections of the cooling canal system may exhibit salinities and water temperatures above the known limits of tolerance for the crocodile. Crocodiles respond to high water temperatures by moving into areas of lower temperature within or outside of the cooling canal system.
See station locations and graph below. Crocodiles are also able to survive the hypersaline environment by excreting salt through salt glands in their tongue, but require access to freshwater to persist. Sources of freshwater are known to occur at various localities within the cooling canal system (i.e., depressions and specially constructed ponds that collect rainwater runoff located on the canal systems berms), and outside of the cooling canal system within the adjacent interceptor ditch and freshwater marsh.

FPL has projected an increase in temperature of about 3 O F, and an increase in salinity in the cooling canal system. The effect of an increase in water temperature and salinity of this magnitude on the crocodile population within the cooling canal system is unclear. However, an increase in water temperature could conceivably reduce the amount of habitat suitable for crocodiles in the cooling canal system during the warmest part of the year. As discussed, crocodiles within areas of unsuitable water temperatures may relocate to areas of the cooling canal system with more favorable temperatures.
Because crocodiles are known to maintain well defined social hierarchies based on access to resources such as preferred temperature regimes, animals lower in social hierarchy could be displaced from the cooling canal system. The effect of increased water temperature and salinity could also reduce hatchling survival because hatchlings are more limited in their ability to behaviorally thermoregulate and excrete salt than adult crocodiles. Based on the unknown effects of the proposed LAR, the NRC has determined the project may affect, and is not likely to adversely affect the American crocodile, and may result in an adverse modification to critical habitat.
Because the effects to crocodiles from the possible slight increase in water temperature and salinity in the cooling canals due to the LAR are unclear, FPL will continue their crocodile monitoring efforts in the project area. Specifically, FPL will continue to evaluate growth, survival, abundance, and spatial distribution of crocodiles at the Turkey Point site following the Uprate and LAR. Mark/recapture surveys (three capture events per year), and spotlight surveys (conducted quarterly) are proposed to ascertain this information. Twenty-six data loggers located throughout the cooling canal system will be used to record water temperature and salinity immediately prior to each survey. To provide a baseline of the crocodile population before the LAR approval, FPL has completed four years of baseline monitoring Pre Uprate and 1 year Post Uprate using the methods described above. See attached table.

Through May 2013 and spotlight surveys. In 2014, reduced from Bi-monthly to Quarterly 2
Three more nest expected to hatch An additional 2 years of monitoring are proposed following implementation of the LAR. FPL will provide a report to the Service detailing the results of monitoring on a semi-annual basis. Should the monitoring reveal measurable, negative effects on the crocodile in this area, it will be considered additional information involving effects on a listed species and NRC (or FPL on their behalf) should contact the Service to reinitiate consultation.
This letter fulfills the requirements of section 7 of the Act and further action is not required. If modifications are made to the project, if additional information involving potential effects to listed species becomes available, or if a new species is listed, reinitiating of consultation may be necessary.

Turkey Point Aquifer Withdrawals and Canal Maintenance Hello Briana, There are two aquifers below the Cooling Canal System (CCS). The shallow aquifer is call the Biscayne Aquifer (approximately 90 feet deep) The deeper aquifer is called the Floridan Aquifer. There is a confining layer between the two aquifers. The current approved temporary water withdrawals are approximately 5 MGD from the Floridan Aquifer. The future withdrawals that FPL will request approval for from the South Florida Water Management District will be 14 MGD from the Floridan Aquifer. FPL also received temporary approval for an additional 30 MGD withdrawal from the saline portion of the Biscayne Aquifer. FPL has not utilized the 30 MGD withdrawal.

Biological Assessment on the Potential Effects of a Proposed Turkey Point Nuclear Generating Unit Nos. 3 and 4 License Amendment on the American Crocodile 1.0 Introduction This biological assessment has been prepared to support the U.S. Nuclear Regulatory Commission (NRC)s review of Florida Power & Light Co. (FPL)s license amendment request (LAR) dated July 10, 2014, and to comply with the provisions of section 7 of the Endangered Species Act of 1973, as amended (ESA). This biological assessment examines the potential impacts of the Turkey Point Nuclear Generating Unit Nos. 3 and 4 (Turkey Point) on the American crocodile (Crocodylus acutus) under the proposed license amendment conditions.
NRC has been in coordination with U.S. Fish Wildlife Service (FWS) staff at the Vero Beach South Florida Ecological Services Office since regarding the proposed license amendment. Additionally, the NRC and U.S. Fish and Wildlife Service (FWS) have previously consulted under Section 7 of the ESA for Turkey Point on a number of occasions. Section 4.0 contains a brief history of section 7 consultations between the FWS and NRC.
2.0 Description of the Proposed Action 2.1 Proposed Action The proposed action is NRCs decision whether to approve FPLs request for an amendment to the Turkey Point Technical Specifications contained in Appendix A of Renewed Facility Operating Licenses DPR-31 (Unit 3) and DPR-41 (Unit 4). The proposed amendment would revise the Turkey Point ultimate heat sink (UHS) thermal limit from 100°F to 104°F. FPL submitted the LAR on July 10, 2014, and supplemented its request by letters dated July 17, July 22, and July 24, 2014 (FPL 2014a, 2014b, 2014c, 2014d). In its July 17, 2014, letter, the licensee requested the NRC to process the LAR expediently (FPL 2014b). If approved, the LAR would be effective from the date of NRC approval through the expiration dates of the renewed operating licenses.
The Turkey Point site includes two nuclear units (Units 3 and 4) and three fossil-fueled units (Units 1, 2, and 5). Units 1-4 use the same closed cooling canal system (CCS) to support operation; Unit 5 draws from the Floridan Aquifer for cooling and does not use the CCS. For the nuclear units, the CCS provides the coolant for the Circulating Water System (CWS) and serves as the UHS for the Intake Cooling Water System (ICWS).
The CWS provides cooling water to the main plant condensers, and the ICWS removes heat loads from the Component Cooling Water System (CCWS) during normal and accident conditions to support both reactor and containment heat removal requirements as well as spent fuel cooling requirements. The proposed amendment would allow the CCS (UHS) temperature to reach 104°F as measured at a the ICWS piping going to the inlet of the CCW heat exchanges at the north end of the CCS.
3.0 Proposed Action Area: Turkey Point Cooling Canal System The Turkey Point site and CCS have previously been described in the NRCs final supplemental environmental impact statement (SEIS) for Turkey Point license renewal (NRC 2002), the FWSs 2006 biological opinion for continued operation of Turkey Point
(FWS 2006a), and the NRCs 2011 biological assessment for the Turkey Point extended power uprate (EPU) (NRC 2011a). This section focuses on the changes that have taken place within the system that have prompted FPLs LAR to increase the UHS temperature limit. Anticipated future changes that would result from the proposed action or other actions taking place on the Turkey Point site are also discussed.
In June 2014, CCS temperatures approached the 100°F Technical Specification limit (e.g., 99.612°F and 99.713°F on June 25 and 29, 2014, respectively) (FPL 2014b). FPL (2014a, 2014e) believes that the recent higher trending temperatures are the result of a combination of factors within the CCS that include (1) high blue green algae concentrations, (2) low water levels associated with lower than average rainfall, and (3) sediment buildup. These factors are described below. Additionally, FPL has received approvals to temporarily withdraw water from the Floridan and Biscayne Aquifers, and approval to withdraw additional water from the Floridan Aquifer is likely forthcoming.
Because the aquifer withdrawals represent a change to the CCS not reflected in previous documents, they are also briefly described below.
Algae In 2011, FPL began to notice increased blue green algae concentrations in the CCS.
The concentrations have steadily increased since that time. FPL has performed engineering and environmental analyses and believes that the presence of higher than normal CCS algae concentrations may be diminishing the CCSs heat transfer capabilities. FPL developed a plan to gradually reduce algae concentrations through controlled chemical treatment of the CCS over the course of several weeks.
On June 18, 2014, FPL (2014h) submitted a request to the Florida Department of Environmental Protection (FDEP) to approve the use of copper sulfate, hydrogen peroxide, and a bio-stimulant to treat the algae. On June 27, 2014, the FDEP (2014) approved FPLs treatment plan for a 90-day trial period. The FDEP requested that during the 90-day treatment period, FPL monitor for total recoverable copper and dissolved oxygen and submit its results to the FDEP. The FDEP also recommended that FPL coordinate with the Florida Fish and Wildlife Conservation Commission (FWC) due to the presence of crocodiles in the cooling system. The FWC (2014) provided its comments on FPLs treatment plan in a letter dated July 1, 2014. Appendix A contains the letters referenced in this paragraph, which provide additional information on the algal treatment plan, timeline, and anticipated effects. FPL also developed a Water Quality Monitoring Plan for the chemical treatments, and this plan is also enclosed in Appendix A.
Low CCS Water Levels FPL (2014e) believes that low rainfall is contributing to higher than average CCS temperatures because the CCS partially relies on rainfall to recharge evaporative loss.
FPL data from a meteorological station in the middle of the CCS indicate that the site has experienced significant lower than average rainfall in 2013 and 2014. Rainfall for the years 2011 through the present are as follows.
Year Rainfall (in.)
2011 52.18 2012 74.25
Year Rainfall (in.)
2013 19.65 2014 (to date) 4.04 The lower rainfall has resulted in a corresponding decrease in CCS water levels.
CCS Elevation Year (ft, in NAVD88) 2012 -0.47 2013 -0.65 2014 (to date) -0.88 Sediment Buildup In addition to rainfall, groundwater exchange supplements CCS evaporative loss. FPL (2014e) has indicated that sediment buildup may be affecting this exchange. The company is evaluating longer term solutions to improve the conditions of the CCS, which may include measures to increase canal aeration and to de-muck the canal bottom (FPL 2014f).
Aquifer Withdrawals The CCS is situated above two aquifers: the shallower saltwater Biscayne Aquifer and the deeper brackish Floridan Aquifer. A confining layer separates the two aquifers from one another. Turkey Point, Unit 5, uses the Floridan Aquifer for cooling water. The South Florida Water Management District (SFWMD) granted FPL approval to withdraw a portion (approximately 5 million gallons per day [MGD]) of the Unit 5 withdrawal allowance for use in the CCS. FPL began pumping Floridan Aquifer water into the CCS in early July. FPL has also received temporary approval to withdraw 30 MGD from the Biscayne Aquifer, though FPL has not yet used this allowance. (FPL 2014f, 2014g)
FPL (2014f) also anticipates the FDEP to issue an Administrative Order requiring FPL to install up to six new wells that will pump approximately 14 MGD of water from the Floridan Aquifer into the CCS. Modeling performed by FPL consultants and the SFWMD indicates that in approximately two years, the withdrawals would reduce the salinity of the CCS to the equivalent of Biscayne Bay (about 34 parts per thousand [ppt]). Such withdrawals could also help moderate water temperatures.
4.0 Section 7 Consultation History 4.1 Informal Consultation for License Renewal NRC first initiated section 7 consultation with FWS regarding Turkey Point in 2001 as part of reviewing the Turkey Point license renewal application. During this consultation, NRC staff considered the potential adverse effects on 23 Federally listed species in its biological assessment (NRC 2001). In this 2001 biological assessment, the NRC concluded that license renewal would either have no effect or may affect, but would not be likely to adversely affect the 23 listed species. In December 2001, the FWS (2001) determined that the proposed license renewal would not adversely affect any listed species.
4.2 Formal Consultation Following Vehicle Collision In 2006, the NRC (2006) requested initiation of formal consultation for ongoing operation of Turkey Point after a juvenile American crocodile was hit by a vehicle on the Turkey Point site. The American crocodile was the only species considered during this consultation, and as a result of the consultation, the FWS (2006a) issued a biological opinion in May 2006. FWS (2006b) subsequently modified the biological opinion in August 2006. The 2006 biological opinion for the American crocodile remains in effect today.
4.3 Informal Consultation for Extended Power Uprate In 2011, following receipt of an LAR for an EPU at Turkey Point, the NRC (2011a) prepared a biological assessment (NRC 2011a) and requested initiation of consultation in a September 2011 letter (NRC 2011b). The biological assessment considers the American crocodile, its critical habitat, and 30 additional species that occur in Miami-Dade county. The FWS (2011) concurred with the NRCs biological assessment and concluded consultation in October 2011.
5.0 Federally Listed Species Considered This biological assessment considers the American crocodile because the proposed license amendment has the potential to affect only this species. The description, distribution, and habitat of the American crocodile have been previously documented in the NRCs 2001 biological assessment, the FWSs 2006 biological opinion, and the NRCs 2011 biological assessment.
FPLs annual crocodile monitoring reports for 2009 through 2013 associated with the EPU are attached as Appendix B and provide additional information on the crocodiles that inhabit the Turkey Point site.
The FWS has designated the majority of the Turkey Point site, including the CCS, as American crocodile critical habitat. The NRCs 2011 biological assessment describes the critical habitat in detail.
6.0 Proposed Action Effects Analysis 6.1 Direct Effects This section considers the potential effects of the proposed LAR to increase the UHS temperature limit from 100°F to 104°F. The proposed action would not directly increase the temperature; it would only increase the allowable temperature at the Technical Specification monitoring station at the north end of the CCS. Under the proposed action, temperatures between 100°F and 104°F would likely be experienced for only short durations during periods of peak summer air temperatures and low rainfall and may not be experienced at all depending on site and weather conditions. Such temperature increases would also increase CCS water evaporation rates and cause higher salinity levels. This effect would also be temporary and short in duration because salinity would again decrease upon freshwater recharge of the system through rainfall, stormwater runoff, and groundwater exchange.
The NRC identified three potential direct effects associated with the proposed action:
(1) reduced hatchling survival, (2) changes in crocodile growth rates, and (3) reduced habitat availability. Each of these potential effects are considered below. The potential
for adverse modification to designated critical habitat is considered together with reduced habitat availability.
Reduced Hatchling Survival Increased CCS water temperatures and resulting higher salinity levels could reduce hatchling survival because hatchlings are more limited in their ability to regulate their body temperature and to excrete salt than adult crocodiles. However, crocodiles respond to high water temperatures by moving into lower temperature areas within or outside of the cooling canal system. The Turkey Point site provides crocodiles access to several sources of non-CSS water, including the sites interceptor ditch, freshwater ponds that collect rainwater on the CCSs berms, and adjacent freshwater wetlands. Following the 2011 section 7 consultation for the EPU, FPL excavated three additional freshwater ponds on existing CCS berms in the southwest portion of the system to provide additional source of freshwater for crocodiles. Crocodiles also have access to the adjacent Card Sound and Biscayne Bay. Because hatchlings are mobile, the NRC staff expects that all of these water sources would be available to hatchlings.
FPLs annual crocodile monitoring reports associated with the EPU (enclosed as Appendix B) do not indicate that hatchling survival has changed as a result of the increased temperatures and salinity experienced in the CCS following implementation of the EPU. FPL (2014e) indicates that no changes in behavior have been identified during daily field observations under the recent high temperature conditions. The NRC staff believes that although the proposed action may affect hatchlings, such effects would never reach the scale of a take. Given the anticipated temporary and short duration of temperature increases between 100°F and 104°F and associated salinity increases, such effects likely could not be meaningfully measured, detected, or evaluated.
Hatchlings would continue to have access to a variety of water sources under the proposed action, which would mitigate any effects resulting from changes in the CCS.
Changes in Crocodile Growth Rates In the 2013 annual crocodile monitoring report, Mazzotti et al. (2013) found that crocodile growth (as change in total length) was affected by air and water temperatures.
Salinity was not found to affect growth, and growth (as change in mass) was not predicted by air temperatures, water temperatures, or salinity. Based on this information, temporary increases in CCS temperatures could affect crocodile growth rates. However, because both air and water temperatures play a role in crocodile growth, and the two factors would occur concurrently (i.e., as air temperatures rise, the CCS temperatures would also rise), the NRC staff does not believe that the proposed action would result in measurable effects that could be directly attributed to proposed action. Additionally, temperature increases would occur for only short durations, and crocodiles are mobile and would be able to avoid areas of higher CCS temperatures during these periods of time by moving to a different portion of the CCS or to another nearby body of water.
Reduced Habitat Availability Increased CCS water temperatures and resulting higher salinity levels could conceivably reduce the amount of habitat suitable for crocodiles in the CCS for short durations during periods of peak summer air temperatures and low rainfall. Such effects may be observed as changes in spatial distribution of individuals, increased competition for resources between individuals, or a decrease in the number of individuals that the Turkey Point site could support (reduced carrying capacity). Because the CCS is within designated critical habitat, adverse modification may also result if any of these effects are experienced.
Crocodiles within areas of unsuitable water temperatures may relocate to areas of CCS with more favorable temperatures. Kernal density estimation (KDE) maps of crocodile locations within the CCS during spotlight surveys throughout the year indicate that crocodiles tend to congregate in the southwest corner of the CCS during the summer.
These maps are included in the annual crocodile monitoring reports enclosed in Appendix B. Crocodiles would regain any temporary decreases in available suitable habitat once air and CCS temperatures drop. As previously mentioned, crocodiles have access to several other sources of water on and near the Turkey Point site. Thus, the NRC staff does not believe that any temporary reductions in suitable habitat experienced as a result of the proposed action would result in measurable changes in spatial distribution of individuals. FPL (2014f) indicated that despite the recent high temperatures in the CCS, crocodiles are exhibiting their normal distribution patterns for this time of the year during daily field observations.
Crocodiles maintain well-defined social hierarchies based on access to resources such as preferred temperature regimes. Thus, animals lower in social hierarchy could be displaced from the CCS during periods of higher CCS temperatures. However, because such displacement would likely be temporary and because crocodiles are mobile and could move to other waterbodies on and near the Turkey Point site, the NRC does not believe that the proposed action would increase competition for resources between individuals in a manner that could be meaningfully measured, detected, or evaluated.
Decreased carrying capacity would be expected to result if the proposed action permanently reduced or altered the available water resources on the Turkey Point site.
However, because periods of higher temperatures would be temporary and because the crocodiles have access to non-CCS water and habitat both on and off the site, the proposed action is unlikely to affect the carrying capacity of the site. Additionally, because the crocodile population continues to grow, there is no indication that the sites population is at or near carrying capacity, although such an effect could not be meaningfully measured or detected at this time.
Regarding whether temporary reductions in suitable habitat would constitute adverse modification to critical habitat, the FWS determines destruction or adverse modification to designated critical habitat on the basis of whether, with implementation of the proposed Federal action, the affected critical habitat would continue to serve its intended conservation role for the species and to support the species life-history needs (79 FR 39756). The proposed action would not affect the Turkey Point sites ability to support the population of crocodiles that currently inhabit the site, and the annual monitoring reports indicate that the population continues to thrive despite the unusually hot and hypersaline conditions of the CCS. Thus, the NRC staff does not believe that the proposed action would result in adverse modification to the designated critical habitat on the site.
6.2 Indirect Effects The NRC did not identify any indirect effects associated with the proposed action.
6.3 Interrelated and Interdependent Effects The proposed action is separate from FPLs chemical treatment plan to reduce CCS algal concentrations because the FDEP, and not the NRC, has the authority to approve such treatments. However, the NRC considers this action to be interdependent to the proposed action because it has no independent utility apart from continued operation of
Turkey Point. Accordingly, the NRC briefly considers the effects of CCS chemical treatment on crocodiles in this section. The NRC also considers the aquifer additions to the CCS to be an interdependent action, and the effects of this action are discussed below, as well.
Effects of CCS Chemical Treatments Documents related to FPLs chemical treatment plan to reduce CCS algae concentrations are enclosed as Appendix A, and these documents provide details on the specific concentrations, duration, and application of copper sulfate, hydrogen peroxide, and bio-stimulant. The FDEP has limited the treatment to 90 days, and the FWC (2014) did not have any concerns regarding effects to crocodiles as a result of the treatment.
FPL will continue its regular crocodile monitoring during this time and would report any sign of impacts related to the treatment to the NRC and FWS. Since initial treatment, which began on July 2, 2014, FPL (2014f) has not observed any behavioral or distributional changes or any other noticeable differences that would indicate effects to crocodiles resulting from the chemical treatments.
Effects of Aquifer Withdrawals The current and anticipated future aquifer withdrawals would result in beneficial effects to crocodiles inhabiting the Turkey Point site. FPL anticipates that the withdrawals will reduce the salinity of the CCS to about 34 ppt and could also help moderate CCS temperatures over the long term. Both of these effects would create favorable conditions for the crocodile.
6.4 Cumulative Effects The NRC did not identify any cumulative effects associated with the proposed action.
7.0 Conclusion and Determination of Effects American Crocodile The NRC staff concludes that the proposed action may affect, but is not likely to adversely affect the American crocodile. The increase in the allowable UHS (CCS) temperature from 100°F to 104°F under the proposed action could result in insignificant or discountable effects to hatchling survival, crocodile growth, and effects related to reduced habitat availability. Such effects would be experienced for only short durations during periods of peak summer temperatures and may not be experienced at all depending on site and weather conditions. The crocodiles on the Turkey Point site have already adapted to the sites conditions, which include temperatures and salinities above the species typical preferences. Crocodiles may also adapt to conditions under the proposed action without measurable or detectable impacts. The current and future aquifer withdrawals would result in beneficial impacts to the species and could negate any impacts of the proposed action once the withdrawals are fully implemented.
As a result of the EPU, which was fully implemented in 2013, the FDEPs amended Site Certification continues to require FPL to monitor crocodiles and prepare annual reports that address any observed impacts to crocodiles, including changes in growth, survival, abundance, and spatial distribution. Such monitoring would continue under the proposed action and would provide valuable information to determine if the UHS LAR results in unanticipated adverse impacts in the future.
American Crocodile Critical Habitat The NRC staff concludes that the proposed action would have no effect on designated critical habitat because the CCS would continue to serve its intended conservation role for the species and would continue to support the species life-history needs. The annual monitoring reports indicate that the Turkey Point crocodile population continues to thrive despite the unusually hot and hypersaline conditions of the CCS. Future monitoring reports would document any unanticipated adverse impacts that result from the UHS LAR.

Appendix A Documents Related to the Florida Department of Environmental Protections Approval of Chemical Treatment to Control Blue Green Algae in the Cooling Canal System
June 18, 2014 L-2014-191 Mr. Marc Harris Industrial Wastewater Section Florida Department of Environmental Protection 2600 Blair Stone Road Tallahassee, Florida 32399-2400 RE: FPL-Turkey Point Units 3 and 4 Wastewater Permit FL0001562 Request for Approval for the Use of Copper Sulfate, Hydrogen Peroxide and a Bio-Stimulant in the Treatment and Control of Blue Green Algae in the Cooling Canal System (CCS)
Florida Power and Light Company (FPL) is herein requesting Florida Department of Environmental Protection (FDEP) to approve the short term use of copper sulfate, hydrogen peroxide, and a bio-stimulate as part of a mitigating strategy for reducing or eliminating Turkey Point Cooling Canal algae growth. We recommend that this action be approved as construction, replacement or repair of components of an industrial site or plant, pursuant to Rule 62-620.200(26)(b), Florida Administrative Code.
Both Turkey Point Nuclear Operating Units are currently experiencing a high incidence of condenser tube and auxiliary heat exchanger tube biofouling, reduced heat transfer (a viscosity affect), and higher than normal canal temperatures. This is causing MWe reductions, more frequent heat exchanger cleanings and reduced margin to our design conditions. In addition, the intake weir baskets and screens are experiencing a higher than normal loading due to algae buildup. These declining changes in equipment efficiencies and greater than expected maintenance requirements have been recently noted in the power plant operating data, and were initially noticed during the fourth quarter of 2013. The water quality in the cooling canal has appeared to change since late 2013, and through laboratory testing, FPL has determined that the change is attributed to a high concentration of blue-green algae (cyano bacteria) in the water column.
At this time, the factors contributing to the increased algae growth are being evaluated by FPL and our independent contractor.
The Site has formed a team of engineers and environmental specialists to evaluate the water quality concerns and recommend a course of action to improve the canal water quality and to effect an improvement in the plants operations and maintenance programs. This team has been supplemented with engineers from Enercon Services, Inc. (ENERCON). ENERCON reviewed a number of potential options to control the algae in the CCS, and they have recommended the chemical treatment discussed within this letter. The algae treatment is anticipated to continue for approximately seventy five to ninety days.
While immediate eradication of the algae is possible and highly desirable from a plant operation perspective, there are biological impacts from a sudden algae die off and decay that must be mitigated and/or avoided. An immediate algae kill would likely cause a spike in biological oxygen demand (BOD), as well as, a release of toxins that could result in a fish kill and/or harm Florida Power & Light Company 9760 SW 344 St Homestead, FL 33035 A-2
L-2014-191 Page 2 of 4 the crocodiles. While a gradual reduction in algae concentration is preferred due to the concerns mentioned above, FPL has an urgent need to control the algae prior to the peak heat loading conditions anticipated in the summer months. To balance the two, a near-term corrective action has been identified to reduce the algae population in the near term while a more long-term solution is identified, developed and implemented.
The recommended approach is to apply copper sulfate, a bio-stimulant and hydrogen peroxide to the CCS in a staged treatment plan. This recommended approach is outlined below.
Chemical Treatment Approach Light applications of copper sulfate and a bio-stimulant will work synergistically to reduce the algae population. The bio-stimulant will enhance the respiration rate of the existing bacteria to initiate degradation of accumulated sludge materials in the bottom of the CCS. An initial shock dosage of the bio-stimulant will significantly aid in "jump starting" the degradation process. To prevent the dead algae from causing water quality issues, as well as to facilitate the biological digestion of the sludge in the bottom of the CCS, the copper sulfate/bio-stimulant application will be preceded and followed by applications of hydrogen peroxide added directly into the CCS.
ENERCON recommends that the algae populations be reduced in stages throughout the CCS in an effort to prevent adverse impacts from a quick algae kill within the entire canal system. The CCS will be divided into either two or three zones (See Attachment 1). Zone one will be treated weekly with copper sulfate, bio-stimulator, and hydrogen peroxide. FPL will assess the effectiveness of treatment in Zone 1, and determine whether or not to also move treatment into Zones 2 and 3.
Temperature, total nitrogen, total phosphorus, and pH data will be monitored at one or more surface water monitoring locations within the canal, and the results will be reviewed weekly during the chemical treatment period. This initial weekly application will continue until such time as a long-term solution is implemented or weather conditions allow the curtailment of these efforts. When applied at label rates, copper sulfate is safe and not toxic to fish, crocodiles and other wildlife found in and around the CCS; however, to be conservative, ENERCON recommends applying copper sulfate below label rates to build in a safety buffer. provides the Material Safety Data Sheets for the three chemicals scheduled for use in the canal.
Chemical Information Copper sulfate: Copper sulfate is available in powder, crystal or liquid form, and must be dissolved in water before it is applied to the CCS. Plating or metal replacement issues are not anticipated from the copper sulfate on the heat exchange units. The copper sulfate will be applied at relatively low rates; therefore, the concentration of free copper will be limited in the CCS. The canal pH is slightly alkaline, approximately 8.5, which means that once applied, the free availability of copper is nearly nonexistent. As a result, the free copper will be attenuated to soil particles in the bottom of the CCS. The pH would have to drop below approximately 4.0 (which is unlikely), before the copper will go into solution and potentially impact the heat exchange units.
A-3
L-2014:.191 Page 3 of 4 Copper sulfate is widely used in the control of algae, and when used at manufacturer label recommended doses, it has been demonstrated to not harm aquatic animals. The U.S. EPA completed registration of copper sulfate as an algaecide in 2009 (Boone, et al., 2012).
Bio-stimulant: The bio-stimulant is a combination of bacteria, enzymes and polymers that increases microorganism activity and will accelerate the digestion of sludge in the bottom of the CCS. It is not expected that these organisms will have any adverse effects on the heat exchange units. As the sludge in the CCS is digested, the nutrient levels will be lowered which will reduce the algae population. An additional benefit is that the digestion of the organic material in the bottom of the CCS may increase the total volume of water, which may improve the CCS heat exchange properties.
Hydrogen peroxide: To mitigate the oxygen depleting effects of the copper sulfate and to facilitate the biological digestion of the sludge at the bottom of the CCS, hydrogen peroxide will be applied along with the copper sulfate.
Hydrogen peroxide is a standard oxidizer that is often used in the aquaculture industry as an oxidizer for fish populations. In simple terms, it is a water molecule with an extra loosely bonded oxygen atom attached, which will be released to the water column upon application.
The hydrogen peroxide will be applied in a liquid stream to maximize the amount of oxygen that is released and available to the organisms in the CCS. Because the hydrogen peroxide is applied directly to the canal water, the loosely bonded oxygen atom is expected to release quickly with no direct or indirect negative impacts to the heat exchange units.
The recommended application rates for each treatment option have not been finalized; however, approximate dosages are provided below for planning purposes. A summary of the recommended near-term option chemicals, application rate, and notes on corrosive potential to the plant equipment is provided in Table 1.

1.0 Background
The cooling canal system (CCS) at Turkey Point Nuclear Generating Facility (PTN) is not cooling efficiently due in part to excessive growth of blue-green algae (algae). The CCS is approximately 169 miles long with an approximate footprint of 5 miles by 5 miles and contains approximately 3.5 billion gallons of water during normal operations.
Enercon Services, Inc. (ENERCON) has prepared a treatment process to control the algae population in the CCS. This will be accomplished through the application of a copper sulfate product, hydrogen peroxide, and a bio-stimulant.
Part of the ENERCON process includes monitoring selected water quality parameters as a way to monitor the success of the chemical treatment and to monitor for any unexpected environmental impacts in the CCS.
2.0 Water Quality Monitoring Plan Water quality will be monitored on two sampling regimes simultaneously; a data set collected weekly, and a suite of data collected daily. A background set of data will be collected prior to the start of the chemical treatment.
The weekly data set will include the standard data collection at existing PTN surface water quality data collection points. The analysis will be in accordance with the Florida Department of Protection (FDEP) approval letter issued by the FDEP on June 27, 2014. The weekly laboratory water quality parameters are:
Total nitrogen
Total phosphorous
Total recoverable copper These data will be collected each Monday morning throughout the treatment effort. In addition, algae cell counts will be collected two times per week (Monday and Thursday) at three locations (TPSWCCS-1, TPSWCCS-4, and TPSWCCS-6) throughout the treatment effort.
The daily data set will include field parameters from four existing PTN surface water quality data collection points (TPSWCCS-1, TPSWCCS-3, TPSWCCS-4, and TPSWCCS-6; Figure 1), as well as one supplemental station located at the injection location. The following water quality data will be collected from these locations using an YSI Model 556 multi-meter or equivalent, provided by NEE, will be used to collect and monitor the following parameters:

Typically, the lowest dissolved oxygen (DO) readings would be expected shortly after daylight prior to the onset of daily photosynthesis. The highest DO reading would be expected to be in early to midafternoon.
In addition to the field data collected by ENERCON, NextEra Energy (NEE) will provide data from sampling points located in the CCS (Figure 1). This data will include:
Salinity
Specific conductance
Water temperature This data is collected at one-hour intervals and will be provided to ENERCON by NEE on a daily basis.

ANNUAL REPORT AMERICAN CROCODILE MONITORING PROGRAM FOR THE TURKEY POINT UPRATE Prepared by:
Frank J. Mazzotti, MichaelS. Cherkiss, and JeffreyS. Beauchamp Department of Wildlife Ecology and Conservation Fort Lauderdale Research and Education Center University of Florida 3205 College Avenue Fort Lauderdale, FL 33314 Prepared for:
Stacey Foster Florida Power and Light Company PO #4500473320 2009 B-4
Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development suppot1ing a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to listing the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980's to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps.
While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power and Light's Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).
Adult crocodiles were first observed at TP in1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al. 1995). Rice et al. (2009) reported that one thousand three hundred and tln*ee crocodile nests were located in the tln*ee nesting areas (776 in ENP, 195 at CLNWR and 776 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98% (N = 332) and the lowest annual variation (91-100 %) in success. In several years FPL is planning an uprate, which will increase temperatures and salinities within the cooling canal system, possibly having an effect on crocodile growth, survival, distribution, and abundance.
Project Objectives:
I. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.
2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.
Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.
2 B-5
Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events were organized to cover as much of the system as possible, while concentrating effort in areas where crocodiles were known to be present. Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL),
snout-vent length (SVL), total length (TL), tail girth (TG), mass, and when possible sex was determined. Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time.
Capture data is recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct 5potlight surveys to locate crocodiles.
To determine spatial distribution and encounter rate of crocodiles at TP, monthly spotlight surveys were conducted of the entire cooling canal system over 2-4 nights.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed once a month via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data are backed up on the PDA upon completion of each nightly survey. The PDA is then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Nineteen temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record temperature every 30 minutes were deployed throughout the TP cooling canal system (Figure I). Fifteen recorded water temperature and four air temperature. Dataloggers were downloaded monthly, on the same days as the spotlight surveys. Salinity (measured in parts per thousand) was measured at predetermined locations using a hand held refractometer once a month at the time of each survey (Figure I). Wind speed (measured with a Kestrel 2000), cloud cover, and moon phase were also recorded at the beginning of each survey.
Task 3. Pe1jorm data analysis 3
B-6
Analysis of growth and survival of crocodiles followed procedures used by Rice et al. (2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system monthly and regression was used to evaluate whether monthly surveys are required, or if surveys could be completed every other month without compromising the information being collected. Spatial distribution of crocodiles in relation to salinity and temperature was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.
Results Task I.
Two capture events were conducted at TP during 2009, the first in January and the second in May. One hundred twenty four crocodiles were captured, of which 8 were captured twice during the same capture event; duplicate data is not included in the table (Table I, Figure 2). Thirteen percent (15) were young of year, sixty-six percent (76) were juveniles (0.65 to< 1.5 m TL), sixteen percent (19) were subadults (1.5 to< 2.25 m TL),
and five percent (6) were adults(::>_ 2.25 m TL). In addition, there were 96 recaptures of 82 individual crocodiles, whose time between captures ranged from a few months to over 25 years. Growth was calculated for 70 of the 82 individuals (Table 2). Initial capture records for the remaining 12 were not available. Hatchling crocodiles accounted for 79%
(55) of original captures. Change in total length ranged from -0.02 to 0.28 em/day and change in mass from -8.66 to 25.58 g/day. Survival of hatchlings for TP during the first year was calculated from the existing database using direct enumeration with and without the two capture events from 2009 for the period of2002 through 2008 (Table 3) .
Hatchling first year survival with the capture events ranged from I% to 6%, higher than without the 2009 capture events.
Task 2.
Monthly spotlight surveys were performed at TP between I October 2008 and 30 September 2009. A total of 1309 observations of crocodiles were made (Table 4), of which size estimates were possible for 1124. Of those, 282 (25.1 %) were hatchlings, 369 (32.8 %) juveniles, 300 (26.7 %) subadults, and 173 (15.4 %) adults. In addition, 185 animals could not be placed in a qumter meter size class and were categorized as unknown (138), large (17), medium (13) and small (17).
Chi square analysis was significant for the difference in total number of crocodiles observed between sections of the cooling canal system for several of the months (Table 5). Regression analysis showed a decrease in the overall number of crocodiles/km in relation to increased mean monthly water temperature (Figure 3), with juveniles being the only size class to show an increase in observations with an increase in water temperature (Figure 4). Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year. For example, Figures 5-9 show a change in core area use during the breeding season. Finally, regression analysis showed no difference in the power of bimonthly and monthly surveys 4
B-7
to detect changes. Confidence intervals for 12 month, six month odd and six month even schedules overlapped between each scenario (Table 6).
Environmental Data Based on water temperatures recorded throughout the cooling canal system, we found temperature varies seasonally and spatially (Figure I 0) with warmer temperatures in the northern and eastern sections of the discharge canals. The number of temperature loggers used in 2009 allowed us to roughly describe the cooling canal system thermally, but were not adequate for a detailed model approach. Tlu*ough interpolation, we were able to determine 24 temperature loggers are required to adequately describe the system.
Conversely, monthly salinity measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatially (Figure II).
Summal'y and Recommendations In several years FPL is planning an uprate, which will increase temperatures and salinities within the cooling canal system, possibly having an effect on crocodile growth, survival, distribution, and abundance. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the uprate. In the past year, we found that crocodiles of all size classes are found throughout the system. There was a decrease in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with juveniles being the only size class to show an increase in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system monthly. Seventy-eight percent of crocodiles captured were previously marked and 80% were originally marked as hatchlings, providing valuable growth and survival information.
We recommend for year two to increase the number of temperature sensor loggers, in order to characterize the system thermally and enhance the ability to model habitat suitability for crocodiles using temperature, salinity and habitat. We will reduce spotlight surveys effort to every other month and increase captures by a third effort, to better quantify survival and growth of crocodiles.

I ntl'oduction The American crocodile (Crocodylus acutus) is a coastal crocodilinn that occurs primarily in extreme southern mninland Florida and northern Florida Keys (Kushlan and Mazzetti 1989, Mazzetti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Deach, Broward, Minmi**
Dade, and Monroe Counties, has been the primary cause of endnngerment for C. acutus (Mazzetti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to listing the Florida population of C. acutus ns endangered in 1975 (Federal Register 40:44151 ). However, in 2007, based on results of ongoing monitoring studies from the early 1980's to the present (Moler 1992, Brandt et al. 1995, Mazzotti et nl. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastnl species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging fmm fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to distmbed ot* matHtwde habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades
National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Company's Turkey Point Power Plant {TP) site (Thorbjarnarson 1989, Mazzetti et al. 2007).
Adult crocodiles were first observed at TP inl976. In 1978, nesting was discovered when hatchling crocodiles were observed nnd captured in the cooling canals (Brandt et al.
1995). Rice ct al. (2009) reported that one thousand three hundred and three crocodifc nests were located in the tlU"ee nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid thnt produce at least one hatchling) between 1978 and 2008 at 98 % (N =
332) and the lowest annual vmiation (91 -100 %) in success. FPL is platming an Uprate, which will slightly increase temperatures and salinities within the cooling canal system.
The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.
l,roject Objectives:
I. Determine growth and smvival of crocodiles at the Tmkey Point Power Plant site.
2. Determine spatial pattcm of crocodiles at TP in relation to temperature and salinity.
2 B-60
Methods Task 1. Conduct caplure surveys for growlh and survival of crocodiles.
Growth and smvival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Captme events were organized to cover as much of the system as possible, while concentrating effort in areas where crocodiles were known to be present.
Crocodiles were captmed using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captmed crocodiles, we measured head length (HL), snout~vent length (SVL), total length (TL), tail girth (TG), mass, and when possible sex was determined.
Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an rmimal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct spotlight surveys lo locate crocodiles.
To determine spatial distribt1tion and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-4 nights every other month.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (10) canal was smveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight smvcy data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Twenty-six temperature sensitive data loggers (Onset Tidbi'r'lil v2 Temp) set to record water temperatme every 30 minutes were deployed throughout the TP cooling canal system, and downloaded before each smvey (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figme 1). Wind speed (measured with a Kestrel2000),
cloud cover, and moon phase were also recorded at the beginning of each survey.
3 B-61
Task 3. Pelform data analysis Analysis of growth and survival of crocodiles followed proccdmes used by Rice et al.
(2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles in relation to salinity and temperature was assessed using a geographic information system in combination with logistic regression and Kcmel Density Area analysis.
Results Task 1.
Three capture events were conducted at TP during 20 l 0, the first in January second in May and third in November. One hundred eighty-six crocodiles were captured, of which 6 were captmed twice dming the same capture event; duplicate data is not included in the table (Table l, Pigure 2). Twenty-nine percent (53) were young of year, 47% (85) were juveniles (0.65 to < 1.5 m TL), 17% (30) were subadults ( 1.5 to < 2.25 m TL), and 7%
(12) were adults(~ 2.25 m TL). In addition, there were 150 rccaptmes, whose time between captmes ranged from a few months to over 26 years. Growth was calculated for l 04 for whom original capture information was available (Table 2). Change in total length ranged from 0.013 to 0.196 em/day and change in mass from -0.014 to 36.388 g/day. Smvival of hatchlings for TP was calculated from the existing database using direct enumeration with the capture events from 2009 and 201 0 for the period of 2002 tlU'ough 2009 (Table 3). Hatchling first six month survival ranged tl*om 1% to 7%.
Task 2.
Monthly spotlight smveys were performed at TP between 23 February 2010 and 9 December 2010. A total of 500 observations of crocodiles were made (Table 4), of which 418 were placed in a size class. Thirteen (3 %) were hatchlings, 216 (43 %)
juveniles, 116 (23 %) subadults, and 73 (15 %) adults, with the remaining 82 (16 %)
unknown.
Chi square analysis was significnnt for the difference in total number of crocodiles observed between sections of the cooling canal system for a couple of the months (Table 5). Regression analysis.showed an increase in the overall number of crocodiles/km in relation to increased menn monthly water temperature (Figme 3), with adults being the only size class to show a decrease in observations with an incrense in water temperalme (Figure 4). Kemal Density Area analysis of crocodile observations from spot! ight surveys resulted in a change of core area use throughout the year (Figures 5 - 10).
4 B-62
Environmental Data 13nsed on water temperatures recorded throughout the cooling canal system, we found temperature varies scnsonally nnd spntially (Figure 11) with wmmer temperatmes in the northern cmd eastern sections of the discharge cmwls. Conversely, monthly salinity measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatinlly (Figure 12).
SmnllliH'Y nnd Uccommendntions In seveml yenrs FPL is plmming an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may possibly have nn effect on crocodile growth, survival, distribution, and abundnnce. These systematic spotlight and capture surveys provide comprehensive bnseJine data on distribution, abundance, growth and smvival of American crocodiles at Tmkey Point prior to the Uprate. In the past year, we found thnt crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased menn monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system. One hundred and fifty crocodiles captmecl were previously mmkcd and 87 were originally mnrked as a hatchling, providing valuable gmwth and smvival information:
We recommend continuing to perform spotlight smveys every other month and to complete three captme events mumally to continue quantifying survival and growth of crocodiles.

Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to list the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980s to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Companys Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).
Adult crocodiles were first observed at TP in1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al.
1995). Rice et al. (2009) reported that one thousand three hundred and three crocodile nests were located in the three nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98 % (N =
332) and the lowest annual variation (91-100 %) in success. FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. .
The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.
Project Objectives:
1. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.
2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.
2 B-101
Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.
Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events were organized to cover as much of the system as possible, while concentrating effort in areas where crocodiles were known to be present.
Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL), snout-vent length (SVL), total length (TL), tail girth (TG), mass, and when possible, sex was determined.
Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct spotlight surveys to locate crocodiles.
To determine spatial distribution and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-4 nights every other month.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Twenty-six temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record water temperature every 30 minutes were deployed throughout the TP cooling canal system, and downloaded before each survey (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figure 1). Wind speed (measured with a Kestrel 2000),
cloud cover, and moon phase were also recorded at the beginning of each survey.
3 B-102
Task 3. Perform data analysis Analysis of growth and survival of crocodiles followed procedures used by Rice et al.
(2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles in relation to salinity and temperature was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.
Results Task 1.
Three capture events were conducted at TP during 2011, the first in January, the second in May and the third in November. One hundred seventeen crocodiles were captured (Table 1, Figure 2). Seventeen percent (20) were young of year, 65% (76) were juveniles (0.65 to < 1.5 m TL), 14 % (16) were subadults (1.5 to < 2.25 m TL), and 4 % (5) were adults ( 2.25 m TL). In addition, there were 97 recaptures, whose time between captures ranged from 49 days to over 18 years. Growth was calculated for 90 for whom original capture information was available (Table 2). Change in total length ranged from
-0.028 to 0.2840 cm/day and change in mass from 0.1 to 20.408 g/day. Survival of hatchlings for TP was calculated from the existing database using direct enumeration with the capture events from 2010 and 2011 for the period of 2002 through 2010 (Table 3). Hatchling first six month survival ranged from 1% to 7%.
Task 2.
Spotlight surveys were performed at TP every other month between 07 February 2011 and 20 December 2011. A total of 747 observations of crocodiles were made (Table 4),
of which 520 were placed in a size class. Forty-nine (6.6 %) were hatchlings, 199 (26.6
%) juveniles, 206 (27.6 %) sub-adults, and 66 (8.8 %) adults, with the remaining 227 (30.4 %) unknown.
Chi square analysis was significant for the difference in total number of crocodiles observed between sections of the cooling canal system for a couple of the months (Table 5). Regression analysis showed an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature (Figure 3), with adults being the only size class to show a decrease in observations with an increase in water temperature (Figure 4). Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year (Figures 4 - 9).
Environmental Data Based on water temperatures recorded throughout the cooling canal system, we found temperature varies seasonally and spatially (Figure 10) with warmer temperatures in the northern and eastern sections of the discharge canals. Conversely, monthly salinity 4
B-103
measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatially (Figure 11).
Summary and Recommendations In several years, FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may possibly have an effect on crocodile growth, survival, distribution, and abundance. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the Uprate. In the past year, we found that crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system. One hundred and seventeen crocodiles were captured, of that 90 provided valuable growth and survival information.
We recommend continuing to perform spotlight surveys every other month and to complete three capture events annually to continue quantifying survival and growth of crocodiles.

Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to list the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980s to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Companys Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).
Adult crocodiles were first observed at TP in1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al.
1995). Rice et al. (2009) reported that one thousand three hundred and three crocodile nests were located in the three nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008. Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98 % (N =
332) and the lowest annual variation (91-100 %) in success. FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system.
The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.
Project Objectives:
1. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.
2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.
B-145
Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.
Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events in 2012 were organized to concentrate effort in areas where crocodiles were known to be numerous. Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL), snout-vent length (SVL), total length (TL),
tail girth (TG), mass, and when possible, sex was determined. Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data are entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct spotlight surveys to locate crocodiles.
To determine spatial distribution and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-3 nights every other month.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Twenty-six temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record water temperature every 30 minutes were deployed throughout the TP cooling canal system, and downloaded once a month (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figure 1). Wind speed (measured with a Kestrel 2000),
cloud cover, and moon phase were also recorded at the beginning of each survey.
B-146
Task 3. Perform data analysis.
Analysis of growth and survival of crocodiles followed procedures used by Rice et al.
(2009). A Chi Square analysis was used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.
Results Task 1.
Three capture events were conducted at TP during 2012, the first in January, the second in April and the third in November. Ninety-eight crocodiles were captured (Table 1, Figure 2). Forty-two percent (41) were young of year, 44% (43) were juveniles (0.65 to <
1.5 m TL), 11 % (11) were subadults (1.5 to < 2.25 m TL), and 3 % (3) were adults (
2.25 m TL). In addition, there were 74 recaptures, whose time between captures ranged from 42 days to over 14 years. Growth was calculated for 67 for whom previous capture information was available (Table 2). Change in total length ranged from 0.02 to 0.22 cm/day and change in mass from -0.24 to 29.64 g/day. Survival of hatchlings for TP was calculated from the existing database using direct enumeration with the capture events from 2009 to 2012 for the period of 2002 through 2011 (Table 3). Hatchling first six month survival ranged from 1% to 9%.
Task 2.
Spotlight surveys were performed at TP every other month between 15 February 2012 and 18 December 2012. A total of 675 observations of crocodiles were made (Table 4),
of which 410 were placed in a size class. Thirty-two (4.7 %) were hatchlings, 135 (20.0
%) juveniles, 178 (26.4 %) sub-adults, and 65 (9.6 %) adults, with the remaining 265 (39.3 %) unknown.
Chi square analysis was significant for the difference in total number of crocodiles observed between sections of the cooling canal system for a couple of the months (Table 5). Regression analysis showed an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature (Figure 3).
Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year (Figures 4 - 9).
Environmental Data Based on water temperatures recorded throughout the cooling canal system, we found temperature varies seasonally and spatially (Figure 10) with warmer temperatures in the northern and eastern sections of the discharge canals. Conversely, bimonthly salinity B-147
measurements recorded show salinity changes seasonally throughout the cooling canal system, but less so spatially (Figure 11).
Summary and Recommendations This 2012 monitoring report provides pre-uprate baseline data. In April 2013, FPL completed the uprate projects on Units 3 and 4. The uprate might slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may possibly have an effect on crocodile growth, survival, distribution, and abundance. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the Uprate. In the past year, we found that crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with adults being the only size class to show a decrease in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system.
Ninety-eight crocodiles were captured, of that 67 provided valuable growth and survival information.
We will analyze the data for the possibility of reducing spotlight survey efforts to quarterly and can suggest we do so, as long as there is no statistical loss in detectability from a reduced effort. We will complete three capture events annually to continue quantifying survival and growth of crocodiles.

Introduction The American crocodile (Crocodylus acutus) is a coastal crocodilian that occurs primarily in extreme southern mainland Florida and northern Florida Keys (Kushlan and Mazzotti 1989, Mazzotti 1999). In Florida, habitat loss, due to development supporting a rapidly growing human population along coastal areas of Palm Beach, Broward, Miami-Dade, and Monroe Counties, has been the primary cause of endangerment for C. acutus (Mazzotti 1999, Mazzotti et al. 2007), leading the United States Fish and Wildlife Service to list the Florida population of C. acutus as endangered in 1975 (Federal Register 40:44151). However, in 2007, based on results of ongoing monitoring studies from the early 1980s to the present (Moler 1992, Brandt et al. 1995, Mazzotti et al. 2007), the American crocodile was reclassified from endangered to threatened (Federal Register 72:
13027).
The American crocodile is typically found in freshwater or brackish coastal habitats, including, but not limited to rivers, coastal lagoons, and mangrove swamps. While principally a coastal species, C. acutus is ecologically adaptable and is known to extend its distribution inland, especially along courses of larger rivers, but also into landlocked water bodies, including areas with salinities ranging from fresh to hypersaline conditions (Thorbjarnarson 1989). The adaptability of C. acutus in terms of habitat use extends to disturbed or man-made habitats, which has been observed range wide and is common in southern Florida; American crocodiles use canal berms for nesting within Everglades National Park (ENP), on North Key Largo (CLNWR) and within the cooling canals at Florida Power & Light Companys Turkey Point Power Plant (TP) site (Thorbjarnarson 1989, Mazzotti et al. 2007).
Adult crocodiles were first observed at TP in 1976. In 1978, nesting was discovered when hatchling crocodiles were observed and captured in the cooling canals (Brandt et al.
1995). Rice et al. (2009) reported that 1303 crocodile nests were located in the three nesting areas (776 in ENP, 195 at CLNWR and 332 at TP) between 1978 and 2008.
Turkey Point had the highest rate of nest success (proportion of all nests laid that produce at least one hatchling) between 1978 and 2008 at 98% (N = 332) and the lowest annual variation (91-100 %) in success. FPL is planning an Uprate, which will slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to see if the Uprate may have an effect on crocodile growth, survival, distribution, and abundance.
Project Objectives:
1. Determine growth and survival of crocodiles at the Turkey Point Power Plant site.
2. Determine spatial pattern of crocodiles at TP in relation to temperature and salinity.

Methods Task 1. Conduct capture surveys for growth and survival of crocodiles.
Growth and survival of crocodiles were assessed by capturing crocodiles throughout the cooling canal system. Capture events in 2013 were organized to concentrate effort in areas where crocodiles were known to be numerous. Crocodiles were captured using a self-locking snare, tongs, or, if smaller than 1.0 m, hand grabbed. For all captured crocodiles, we measured head length (HL), snout-vent length (SVL), total length (TL),
tail girth (TG), mass, and when possible, sex was determined. Recaptures of crocodiles with a distinct scute clip pattern or microchip were noted on the data sheets. If an animal had not been previously marked, a microchip was implanted and the crocodile was given a distinct clip pattern as described by Mazzotti and Cherkiss (2003). Capture location was recorded using a GPS (UTM WGS 84), along with air temperature, water temperature, salinity and capture time. Capture data are recorded on waterproof data sheets, which are copied after each capture event. All capture data were entered into an access database, proofed and backed-up on an external hard drive.
Task 2. Conduct spotlight surveys to locate crocodiles.
To determine spatial distribution and encounter rate of crocodiles at TP, spotlight surveys were conducted of the entire cooling canal system over 2-3 nights every other month.
Surveys were performed by airboat, with a driver, second person spotlighting and a third individual recording observations. In addition to the cooling canal surveys, the Interceptor Ditch (ID) canal was surveyed via truck. Surveys were conducted at night, using a 200,000 candlepower spotlight. Crocodile locations were recorded using a GPS (UTM WGS 84) and, when possible, crocodiles were assigned to a quarter meter size class. If size could not be estimated, crocodiles were classified as a hatchling, juvenile, subadult, adult or unknown based on total length.
Observations and size estimates were recorded via personal digital assistant (PDA) in the field or in a field book and then transferred to a PDA. Spotlight survey data were backed up on the PDA upon completion of each nightly survey. The PDA was then synced to a computer, where the data is uploaded to a Microsoft Access database and backed up on an external hard drive.
Environmental Data Twenty-six temperature sensitive dataloggers (Onset TidbiT v2 Temp) set to record water temperature every 30 minutes were deployed throughout the TP cooling canal system, and downloaded once a month (Figure 1). Salinity (measured in parts per thousand) was measured at the start and end of each section and at temperature logger locations 1, 2, 7, 13 and 19 (Figure 1). Wind speed (measured with a Kestrel 2000),
cloud cover, and moon phase were also recorded at the beginning of each survey.
B-188
Task 3. Perform data analysis Analysis of growth and survival of crocodiles followed procedures used by Rice et al.
(2009). Analysis of growth (change in total length and mass) was performed on crocodiles captured between January 2009 and June 2013, as a part of this ongoing project and for any individual that had been previously captured and for whom initial data was available. A one-way analysis of variance (ANOVA) was calculated to detect a difference in growth rates as changes in total length and weight. A t-test was performed to detect differences in growth between male and female animals. Environmental conditions such as air temperature, water temperature, and salinity were used as predictors of growth rates. Regression analysis was run to assess hatchling survival between 2000 and 2012. A Chi Square analysis was also used to determine if crocodiles were distributed randomly through the system. Spatial distribution of crocodiles was assessed using a geographic information system in combination with logistic regression and Kernel Density Area analysis.
Results Task 1.
Three capture events were conducted at TP during 2013, the first in February, the second in June and the third in December. In addition several miscellaneous animals were handled by Mario Aldecoa this year and these data are included here. One hundred and two crocodiles were captured in the cooling canal system in 2013 (Table 1, Figure 2).
Forty-eight percent (49) were young of year, 40% (41) were juveniles (0.65 to < 1.5 m TL), 10 % (10) were subadults (1.5 to < 2.25 m TL), and 2 % (2) were adults ( 2.25 m TL).
Crocodile Growth As a part of this project, a total of 591 crocodile capture events occurred between 2009 and 2013 at Turkey Point. Of these events, 157 hatchlings, 320 juveniles, 88 sub-adults, and 26 adults were captured. A total of 298 crocodiles were recaptured for which we had initial capture data for and were used to calculate growth as changes in total length and weight over time. Hatchlings accounted for 84% of all initial captures, juveniles 13%,
sub-adults 3%, and a single adult was initially caught as an adult and recaptured during this study period (Table 2). Initial measurements of body size as total length and weight ranged from 21-65 cm and 36-900 g in hatchlings, juveniles ranged in size from 65-150 cm and 510-10000g, sub-adults ranged from 151-184 cm and 8700-18400 g, and the lone adult measured 272 cm and 63500 g (means, Table 2). Growth as changes in total length varied across size classes with a range of -0.003 to 0.284 cm/day in hatchlings, -0.006 to 0.083 cm/day in juveniles, 0.017 to 0.080 cm/day in sub-adults, and 0.022 cm/day in the lone adult recapture (Table 2, Figure 3). Changes in weight represent a wider range of growth from -0.183 to 49.372 g/day in hatchlings, -10.938 to 19.351 g/day in juveniles, 3.125 to 29.644 g/day in sub-adults, and 36.388 g/day in the adult recapture (Figure 4),
mean values are presented in Table 2.
B-189
A one-way analysis of variance (ANOVA) was calculated to detect a difference in growth rates as changes in total length and weight. Results illustrate that hatchlings experienced the greatest change in total length relative to all other size classes (F (3, 294) =
952.748, p < 0.001; Tables 2, 3), whereas sub-adults and the lone adult increased in weight significantly more so than hatchlings and juveniles combined (F (3, 294) =
1669.741, p < 0.001; Tables 2, 3). Crocodiles were recaptured anywhere between 3 days to 25 years and at an average of 3 years (Table 2), but there was no difference in the number of days in between capture across the size classes (Table 3). Crocodiles were also recaptured throughout Turkey Point, but a greater number of individuals were captured in Sections 4 and 5 relative to any other section of the cooling canal system (2 = 790.95, df
= 9, p< 0.001; Figure 2).
Of the 298 crocodiles, we recaptured 140 females, 111 males and 47 individuals of unknown sex (Table 4). For purposes of analyses, measurements of only males and females are discussed. At the time of first capture male crocodiles ranged in size from 23-156 cm total length and weighed 39-11000g, and female size ranged from 22-272 cm total length and 42-63500 g in weight (mean measures Table 4). Changes in total length of male crocodiles ranged from 0.000 to 0.196 cm/day, and female growth ranged from
-0.006 to 0.284 cm/day. Mean measures are presented in Table 3. Growth rate as body weight ranged in males from a decrease of weight of -3.600 g/day to an increase of 49.372 g/day, and female growth rate ranged from -10.938 to 36.388 g/day, mean growth rates are presented in Table 3. Independent samples t-test showed that males and females grew at similar growth rates measured as total length (t = 0.527, df = 249, p = 0.598) and there was a positive trend for females to have greater growth rates as weight (t = -1.775, df = 249, p = 0.077). There were slightly more days in between time of capture of females relative to males (1367 days vs. 1076 days) but this was not a significant difference (t = -1.538, df = 249, p = 0.115).
Environmental Conditions Growth was calculated in relation to environmental conditions of the habitat using a combination of data recorded by data loggers stationed throughout Turkey Point and from data collected at the start and end of each survey. Air temperature, water temperature, and salinity were measured throughout the study period. Using environmental conditions as predictors of crocodile growth rates, water temperature was a significant predictor of growth when measured as changes in total length ( = 0.389, p = 0.039), air temperature tended to be a predictor ( = -0.402, p = 0.068), but salinity did not predict growth ( = -
0.045, p = 0.291). The overall model fit for growth as changes in total length was R2 =
0.130, p = 0.236. Growth measured as changes in weight was not predicted by the measured environmental factors of temperature and salinity (R2 = 0.038, p = 0.820).
Water temperature varied seasonally throughout the canal system ranging from 19 to 41°C with peak temperatures occurring in August and lower temperatures registering in December (F = 51.340, df = 11, 304 P < 0.001; Figure 5). Water temperatures also varied significantly within the system, with higher temperatures ranging 27 to 41°C in Section 1 and lower temperatures ranging 19 to 39 °C in Section 6 (F = 19.011, df = 5, 310 P <
0.001; Figure 5). Water temperature significantly decreased as water flowed south (Figure 1 of cooling canal with sections and data loggers). Salinity remained greater than B-190
40 PST (mean 57.52 +/- 0.71 SE) defining Turkey Point as a hypersaline environment and was relatively uniform throughout the canal system (F = 0.113, df = 5, P = 0.989; Figure 6). The Interceptor Ditch (ID) had significantly lower salinity measurements (mean 3.15
+/- 0.766 SE; Figure 6) but is not incorporated in the cooling canal system. There were seasonal fluctuations of salinity across Turkey Point with October registering lower salinities and April registering higher salinities (F = 8.943, df = 5, P < 0.001; Figure 6);
however, mean salinity ranged from 52-63 PPT. Across the survey years, 2009 had the highest salinity records at 62.58 +/- 2.283 SE and the lowest salinity records were from 2012 at 52.78 +/- 1.372 SE.
Survival A total of 3931 hatchling crocodiles were marked from 2000 through 2012 at Turkey Point and of these 243 hatchlings have been recaptured (Table 5). Mean survival of hatchling crocodiles up until 2008 was 3% after which efforts were consolidated to increase systematic surveys. Survival rate has since increased to 11% (Table 5).
Regression analyses show that survey year effectively predicted hatchling survival rate (R2 = 0.764, p < 0.001; Figure 7) largely because the concerted effort ensured a greater numbers of crocodiles being recaptured.
Task 2.
Spotlight surveys were performed at TP every other month between 25 February 2013 and 9 December 2013. A total of 646 observations of crocodiles were made (Table 6), of which 433 individuals were placed in a size class. One-hundred crocodiles (15 %) were hatchlings, 119 (18 %) as juveniles, 139 (22 %) as sub-adults, and 75 (12 %) adults, with the remaining 213 (33 %) unknown.
Chi square analysis of total number of crocodiles observed between sections of the cooling canal system were significant for a couple of the months (Table 7). Regression analysis showed an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature (Figure 8), with subadults being the only size class to show no change in observations with an increase in water temperature. Kernal Density Area analysis of crocodile observations from spotlight surveys resulted in a change of core area use throughout the year (Figures 9 - 14).
Summary and Recommendations This 2013 monitoring report provides pre-uprate baseline data. In April 2013, FPL completed the uprate projects on Units 3 and 4. The uprate might slightly increase temperatures and salinities within the cooling canal system. The purpose of this Monitoring Program is to assess whether the uprate may have an effect on crocodile dynamics. These systematic spotlight and capture surveys provide comprehensive baseline data on distribution, abundance, growth and survival of American crocodiles at Turkey Point prior to the Uprate.
B-191
In the past year, we found that crocodiles of all size classes are found throughout the system. There was an increase in the overall number of crocodiles/km in relation to increased mean monthly water temperature, with sub-adults being the only size class to show no change in observations with an increase in water temperature. There was a significant difference in total number of crocodiles observed between sections of the cooling canal system.
We also analyzed and summarized growth rates (change in total length and mass) for all animals recaptured between 2008 and 2013 during this project. We found growth varied across size classes and that juvenile growth (change in total length) fell within the range previously reported by Mazzotti et al. 2007. We also found that while females and males grew at similar rates measured as total length, there was a positive trend for females to have greater growth rates measured as weight. Growth (change in total length) was affected by air and water temperature, whereas change in mass was not effected by any of the measured environmental parameters. We have also been able to measure hatchling survival through multiple capture events annually. Between the survival information, and the short and long term growth measures gained during this project, this is an excellent example of how long term monitoring programs are able to provide valuable information.
Between October of 2008 and December 2009, we performed monthly spotlight surveys for American crocodiles within the cooling canal system at Turkey Point. This effort was reduced to performing spotlight surveys every other month starting in February 2010 and was continued through December 2013. After completing analysis of the survey data collected over more than four years, between October 2008 and December 2012, we found that we could reduce survey efforts to quarterly without a statistically significant loss in our ability to detect changes in the spatial patterns of crocodiles within the cooling canal system. Therefore, we propose to change the frequency of spotlight surveys from every other month to quarterly beginning with surveys in 2014.

Subject:
Consultation Part 1 of 3 Attachments: NRC FWS Information 1.zip Hello Briana, I am having trouble sending you the documents they keep getting kicked back. I am breaking them out into several emails but please see the text response to your questions last night.
Effects to consider for LAR to increase of UHS to 104 degrees F:
Will the increased temperature or salinities resulting from the LAR reduce hatchling survival through increased stress or other means?
o As described during the Uprate section 7 consultation, Crocodiles respond to high water temperatures by moving into areas of lower temperature within or outside of the cooling canal system. Crocodiles are also able to survive the hypersaline environment by excreting salt through salt glands in their tongue, but require access to freshwater to persist. Sources of freshwater are known to occur at various localities within the cooling canal system (i.e.,
depressions and specially constructed ponds that collect rainwater runoff located on the canal systems berms), and outside of the cooling canal system within the adjacent interceptor ditch and freshwater marsh. Daily field observations have not identified a change in behavior. Data for the annual August surveys will be provided once the 2014 survey is complete.
Will the LAR affect the spatial distribution of crocodiles on the Turkey Point site?
o Based on current daily field observations the crocodiles are exhibiting their normal distribution patterns for this time of the year, concentrating in the south end of the CCS.
Will the LAR reduce habitat availability by decreasing the available suitable habitat in the CCS during the hottest times of the year?
o An increase in water temperature could conceivably reduce the amount of habitat suitable for crocodiles in the cooling canal system during the warmest part of the year.
As discussed, crocodiles within areas of unsuitable water temperatures may relocate to areas of cooling canal system with more favorable temperatures.
Will the LAR increase competition and result in individuals lower in social hierarchy to lose access to CCS waters?
o Response in the attached letter Will the LAR affect crocodile abundance/decrease the crocodile population carrying capacity of the Turkey Point site?
o Response in the attached letter Will the increased temperature affect crocodile growth rates?
o It is not expected to because the crocodiles can move in and out of the system. The canals typically experience the warmest temperatures in July and August.
Will the crocodiles be affected by chemical treatment of the algae?
o The chemical treatment of the algae is planned to be limited to 7-10 weeks. The limited duration of the treatment is not expected to affect the crocodiles.
Will the crocodiles be affected by the addition of aquifer water to the CCS?
o The water from the Floridan aquifer is specifically to reduce the salinity and temperature in the canals. The addition of this water is not expected to negatively impact the crocodiles as it will help to improve the water quality.

Electronic copies of the meeting handouts - in the attached letter Tables of temperature data depicted in handout graphs (if available). - in the attached letter Names of people that you mentioned that do the croc monitoring. You mentioned Mario and Joe. Can you provide last names and associations? I assume Frank is Frank Mazzotti?
o Mario Aldecoa is FPLs onsite biologist that oversees and conducts the nesting and hatchling surveys and ID canal surveys at Turkey Point, as well as participates in the UF IFAS Uprate monitoring. Joe Wasilewski is a wildlife biologist that specializes in working on the natural history of apex predators (crocodilians) within wetlands of south Florida. Previously, he was the onsite biologist at Turkey Point, and now he is a contractor that provides his expert opinion to FPL and assists FPL and UF IFAS with the capture surveys. Dr. Frank Mazzotti is the lead expert overseeing the American crocodile Uprate monitoring conducted by UF IFAS. He has over 25 years of experience researching and teaching issues relating to wildlife and their habitats in South Florida. A major focus of Dr. Mazzotti's research has been evaluating the effects of human activities on crocodilians and their habitats.
Rainfall numbers that Stacey mentioned at the beginning of the meeting (2011-present) and source of that info.
o In attached letter, Source is from the Annual Reports required as a part of the Pre- and Post-Uprate monitoring required by State agencies.
Summary/description of the current and planned aquifer pumping from the Biscayne and Floridian aquifers, including current and pending authorizations, current and future pumping rates, and description of purpose (i.e., to reduce the salinity of the CCS to ~34 ppt within 2 years and halt/reverse the line of salt water intrusion into the Biscayne Aquifer, if I understand correctly). A description of the Water Management Districts Administrative Order to create 6 new wells would be helpful as part of this.
o The Order is expected to come from the Department of Environmental Protection. The order will require FPL to install 6 new wells that will pump approximately 14 MGD of less saline water from the Floridan Aquifer. The Floridan Aquifer is a confined aquifer that is below the Biscayne Aquifer. The modeling performed by FPL consultant and South Florida Water Management District indicates it will take approximately 2 years to get the CCS back to salinity equivalent with Biscayne Bay.
Copies of all pre- and post-uprate crocodile monitoring reports. The only ones that I have a copy of are the two 2013 reports (Dec 30, 2013, report to FWS and July 3, 2014, report to SFWMD) and the May 14, 2014, progress report from Mazzotti. - Reports attached Thanks you, Stacy M.

PROBLEM STATEMENT:
The Turkey Point Cooling Canal System (CCS) is experiencing higher than normal temperature and salinity fluctuation than previously observed. Florida Power and Light Company (FPL) has requested a License Amendment Request (LAR) to increase the Ultimate Heat Sink (UHS) temperature limit from100 degrees Fahrenheit (°F) to 104 °F.
During the Uprating of the Unit 3, beginning in February 2012, flow through the canals was reduced. The Unit began to repower in September 2012, reaching full power in November 2012. In August 2012, FPL visually noticed that turbidity in the CCS was starting to increase. In November 2012, Unit 4 went offline and did not reach 100% power until June 2013. The canals during these outages were at a reduced flow for approximately 17 months. To understand the change in visibility, FPL took water samples and had them analyzed for algae content in August 2012. The results showed that the cell count were approximately 680,000 cells/ml. FPL analyzed for algae in September 2012, and the count had decreased by approximately 55%. In April 2014, FPL noticed the turbidity was increasing and again took samples to analyze for Algae and the cells counts. These results showed that the cell counts were back up. It was determined that the algal counts were affecting the ability of the CCS water to release heat and as a result was one of the factors causing the CCS temperature to increase. FPL requested approval from the Florida Department of Environmental Protection (FDEP) to use algaecide commonly used on ponds to treat the algae as a short term solution. The treatment has been effective in reducing the cell count. The treatment is expected to continue for 4 more weeks.
Both Units have been operating in the Uprated mode since June of 2013. The CCS relies on rainfall and ground water exchange to recharge the system. The CCS has a Meteorological Station in the middle of the system. The data from that system indicates much lower than average rainfall for 2013 and 2014. See rainfall table. This has also resulted in greater than normal temperature and salinity fluctuations in the system. Also, the connectivity with the groundwater appears to be hindered by potential sediment buildup. See water elevation table. (* Unit out for repair half of June 2013).

FPL has several stations that monitor temperature in the CCS on an hourly basis. Below is a time series temperature plot for 4 of those stations. The map identifies the station locations. Station CCS-3 is a station in the area that is utilized most by the crocodiles. The data indicates the temperature fluctuates throughout the year with temperature typically peaking in the month of July. The factor that restricts American crocodiles across their range is access to fresh water for their hatchlings to develop salt excreting glands. The Turkey Point Nuclear Power Plant Cooling Canal System is an ideal situation in order for the population to recruit more individuals. Within the CCS there are numerous fresh water and lower saline ponds where females place the hatchlings for the purpose of developing their salt excreting glands.

FPL is looking at interim and long-term solutions to decrease temperature and salinity in the CCS. Some of these solutions are aeration, sediment removal and introducing fresher Floridan Aquifer waster source to the CCS THREATENED AND ENDANGERED SPECIES EFFECTS:
The project site occurs within the geographic range of the threatened American crocodile (Crocodylus acutus) and is located within designated critical habitat for this species. Crocodiles are known to occur and nest within the 5,900-acre cooling canal system located immediately west of the Turkey Point Power plant. The cooling canal system is a closed system and does not discharge surface water to either Biscayne Bay or adjacent freshwater wetlands. The cooling canal system was originally filled with seawater from Biscayne Bay and is now augmented only by rainfall and freshwater pumped periodically from the Interceptor ditch (located along the western boundary of the cooling canal system) during the dry season. Heated water is currently discharged into the discharge canal located at the north end of the cooling canal system from nuclear power production units 3 and 4 and oil burning power production unit 1 located immediately north of the nuclear units. The heated water circulates to the southern end of the cooling canal system, then east and northward back to the Intake Canal for reuse in cooling units 1, 3, and 4.
The cooling canal system currently supports a large population of crocodiles because the berms constructed in association with the canal system provide high quality nesting habitat. However, the water in the cooling canal system provides a physically challenging environment for crocodiles. Due to the original use of sea water for cooling purposes, the ongoing deposition of heated water from power production, and the limited influx of fresh water, the water in cooling canal system is hypersaline (45 to 95 ppt). At times during the year, sections of the cooling canal system may exhibit salinities and water temperatures above the known limits of tolerance for the crocodile. Crocodiles respond to high water temperatures by moving into areas of lower temperature within or outside of the cooling canal system.
See station locations and graph below. Crocodiles are also able to survive the hypersaline environment by excreting salt through salt glands in their tongue, but require access to freshwater to persist. Sources of freshwater are known to occur at various localities within the cooling canal system (i.e., depressions and specially constructed ponds that collect rainwater runoff located on the canal systems berms), and outside of the cooling canal system within the adjacent interceptor ditch and freshwater marsh.

FPL has projected an increase in temperature of about 3 O F, and an increase in salinity in the cooling canal system. The effect of an increase in water temperature and salinity of this magnitude on the crocodile population within the cooling canal system is unclear. However, an increase in water temperature could conceivably reduce the amount of habitat suitable for crocodiles in the cooling canal system during the warmest part of the year. As discussed, crocodiles within areas of unsuitable water temperatures may relocate to areas of the cooling canal system with more favorable temperatures.
Because crocodiles are known to maintain well defined social hierarchies based on access to resources such as preferred temperature regimes, animals lower in social hierarchy could be displaced from the cooling canal system. The effect of increased water temperature and salinity could also reduce hatchling survival because hatchlings are more limited in their ability to behaviorally thermoregulate and excrete salt than adult crocodiles. Based on the unknown effects of the proposed LAR, the NRC has determined the project may affect, and is not likely to adversely affect the American crocodile, and may result in an adverse modification to critical habitat.
Because the effects to crocodiles from the possible slight increase in water temperature and salinity in the cooling canals due to the LAR are unclear, FPL will continue their crocodile monitoring efforts in the project area. Specifically, FPL will continue to evaluate growth, survival, abundance, and spatial distribution of crocodiles at the Turkey Point site following the Uprate and LAR. Mark/recapture surveys (three capture events per year), and spotlight surveys (conducted quarterly) are proposed to ascertain this information. Twenty-six data loggers located throughout the cooling canal system will be used to record water temperature and salinity immediately prior to each survey. To provide a baseline of the crocodile population before the LAR approval, FPL has completed four years of baseline monitoring Pre Uprate and 1 year Post Uprate using the methods described above. See attached table.

Through May 2013 and spotlight surveys. In 2014, reduced from Bi-monthly to Quarterly 2
Three more nest expected to hatch An additional 2 years of monitoring are proposed following implementation of the LAR. FPL will provide a report to the Service detailing the results of monitoring on a semi-annual basis. Should the monitoring reveal measurable, negative effects on the crocodile in this area, it will be considered additional information involving effects on a listed species and NRC (or FPL on their behalf) should contact the Service to reinitiate consultation.
This letter fulfills the requirements of section 7 of the Act and further action is not required. If modifications are made to the project, if additional information involving potential effects to listed species becomes available, or if a new species is listed, reinitiating of consultation may be necessary.

Turkey Point Aquifer Withdrawals and Canal Maintenance Hello Briana, There are two aquifers below the Cooling Canal System (CCS). The shallow aquifer is call the Biscayne Aquifer (approximately 90 feet deep) The deeper aquifer is called the Floridan Aquifer. There is a confining layer between the two aquifers. The current approved temporary water withdrawals are approximately 5 MGD from the Floridan Aquifer. The future withdrawals that FPL will request approval for from the South Florida Water Management District will be 14 MGD from the Floridan Aquifer. FPL also received temporary approval for an additional 30 MGD withdrawal from the saline portion of the Biscayne Aquifer. FPL has not utilized the 30 MGD withdrawal.
