1.0 INTRODUCTION

Progress Energy Florida, Inc. (PEF) is proposing the construction of a new forced draft cooling tower to mitigate thermal impacts from its planned Extended Power Uprate project at the Crystal River Unit 3 (CR3) Nuclear Plant. The site is located in Section 32, Township 17 South, Range 16 East, in Crystal River, Citrus County, Florida (Figure 1).

The south cooling tower project identified a need for laydown space for tower construction activities. PEF is proposing to develop a 4.13-acre area on the south side of the discharge canal, adjacent to the CR3 Nuclear Facility Training Center (target shooting range) (Figure 2), in order to provide the required laydown area. The laydown area design shall take into account a requirement to modify the north berm at the target shooting range. This berm will need to be extended 100 to 150 feet (ft) and raised to a total height of 20 ft (from the current height of 17 ft) along its full extent.

2.0 METHODOLOGY

2.1 Habitat Classification

Project biologists from Golder Associates Inc. (Golder) identified upland and wetland habitats within and adjacent to the project area through field verification and review of the Florida Department of Transportation's (FDOT) Florida Land Use, Cover, and Forms Classification System (FLUCFCS) Handbook (FDOT, 1999) (Figure 3), U.S. Department of Agriculture (USDA)/Natural Resources Conservation Service (NRCS) soils maps (USDA, 2006) (Figure 4), U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (Figure 5), and Southwest Florida Water Management District (SWFWMD) land use database (SWFWMD, 2007). In addition, Federal Emergency Management Agency (FEMA) databases were also queried (FEMA, 2007) (Figure 6).

Where necessary, upland and wetland habitats were field revised and reassigned FLUCFCS codes according to their predominant vegetative cover.

2.2 Approximate Wetland Delineation

Approximate jurisdictional wetland boundaries were identified in accordance with the U.S. Army Corps of Engineers (USACE) 1987 Wetland Delineation Manual, and the criteria identified in Chapter 62-340, Florida Administrative Code (F.A.C.). Specifically, the site was examined for the presence of hydrophytic vegetation, hydric soils, and hydrologic indicators. The landward extent of jurisdictional wetlands and other surface waters was flagged in the field on March 17, 2009. Neither the wetland nor other surface water boundaries have been reviewed or verified by the regulatory agencies; however, they were marked in the field with high visibility flagging tape and sequentially numbered for future identification.

Wetland and other surface water boundary locations are depicted on the land use/land cover map. Dominant vegetation, soil conditions, and hydrologic indicators were documented for each wetland and other surface water. USACE Routine Wetland Determination Data Forms are included in Appendix A, and USACE Jurisdictional Determination forms are included in Appendix B. Additionally, wetland and other surface water boundary points were surveyed by professional land surveyors and are included in the Topographic Survey (Appendix C).

Golder Associates May 2009 -3- 093-89529

2.3 Listed Species Assessment

The proposed laydown site was assessed for the presence of threatened, endangered, and/or species of special concern in March 2009 via meandering pedestrian transects. Listed plant species are those plants that are listed by the USFWS or the Florida Department of Agriculture and Consumer Services (FDACS) as endangered, threatened, of special concern, or commercially exploited. Listed animal species are those animals that are listed as endangered, threatened, or of special concern federally by the USFWS or within the state of Florida by the Florida Fish and Wildlife Conservation Commission (FFWCC).

County-specific geographic information system data were obtained from the Florida Natural Areas Inventory (FNAI), which maintains a database of known occurrences of listed species throughout Florida. An FNAI report was obtained specifically for the area within 1 square mile of the site, as well as for a ±2-mile radius of that 1-square-mile area (FNAI Map, Matrix Unit ID 21566, Appendix D). In addition, the FFWCC Bald Eagle Nest Locator database (FFWCC, 2009) was used to identify the location and status of any bald eagle nests in the vicinity of the site (Figure 7).

All observations of listed and non-listed wildlife species within and adjacent to the project area were documented. These observations included direct sightings of species or signs of their presence, including tracks, scat, nests, and, typically with avifauna, calls.

2.4 Wetland Functional Assessment

Rather than an acre-for-acre mitigation or the use of mitigation ratios, the calculation of mitigation requirements involves use of a wetland functional assessment value multiplied by the acreage of impact to determine the required number of mitigation credits to offset wetland impacts. Wetland functional assessments typically involve ranking the subject wetland relative to several variables, such as vegetation, wildlife utilization, hydrology, and surrounding landscape conditions. The goal of the functional assessment is to determine the ecological value of the wetland prior to disturbance, to ensure that mitigation is designed to replace the wetland's ecological functions rather than merely the acreage of fill. Using this rationale, a 2-acre wetland dominated by exotic vegetation with altered hydrology and little wildlife utilization would have a lower functional value and thus require fewer mitigation credits as compared to a 2-acre wetland supporting a diverse assemblage of native flora and fauna and unaltered hydrologic regime.

Golder Associates May 2009 -4- 093-89529

Information was collected prior to and during the field reconnaissance in order to prepare a wetland functional assessment for each FLUCFCS type utilizing the Florida Department of Environmental Protection's Uniform Mitigation Assessment Method (UMAM). UMAM quantifies the quality or health of wetlands and other surface waters through evaluation of several variables, including location and landscape support, water environment, and community structure as defined under Chapter 62-345, F.A.C. UMAM scores and associated documents are provided in Appendix E.

3.0 RESULTS

3.1 Habitat Classification/Approximate Wetland Delineation

Uplands

The cooling tower laydown project is on an approximately 4.13-acre site located just north of the CR3 Nuclear Facility Training Center (target shooting range). The proposed laydown area is surrounded to the north, west, and south by a ±10- to 20-foot berm, portions of which were constructed to provide protection from target shooting activities on the adjacent site. Upland land use on the proposed laydown site is limited primarily to Utilities (FLUCFCS 830). This area was composed of ruderal and/or transitional vegetation, including saltbush (Baccharis halimifolia), winged sumac (Rhus copallina), poison ivy (Toxicodendron radicans), Bermudagrass (Cynodon dactylon), fireweed (Erechtites hieracifolius), and flamevine (Ampelopsis arborea). Other vegetation observed included poorman's pepper (Lepidium virginicum), goldenrod (Solidago sp.), bushy broomsedge (Andropogon glomeratus), cranesbill (Geranium carolinianum), Indian clover (Melilotus indica), prickly pear cactus (Opuntia humifusa), and plantain (Plantago virginica). Small areas of disturbed temperate hardwood forest (FLUCFCS 425) were also included in the eastern portion of the site and are dominated by red cedar (Juniperusvirginiana), cabbage palms (Sabal palmetto), and Brazilian pepper (Schinus terebinthifolius).

Historic use of the proposed laydown area site included shrimp farming activities. Pond liner materials and associated debris still exist on the site. Fill material was also historically introduced onto the site in order to construct a haul road and adjacent CR3 Nuclear Facility Training Center. A meteorological tower is housed at the terminus of the haul road.

Wetlands and Other Surface Waters

A Stream and Waterway (FLUCFCS 510), small area of Wetland Hardwood Forest (FLUCFCS 610), were identified within the proposed laydown area project boundary. Additionally, a Saltwater Marsh (FLUCFCS 642) bounds the laydown area to the north and west, while Canals and Locks (FLUCFCS 816) border the site to the south. These wetlands and other surface waters are described below.

Golder Associates May 2009 -6- 093-89529

Streams and Waterways (FL UCFCS 510)

This area consists of a 0.07-acre ditch, located on the northern portion of the laydown area site. The ditch is bisected by an access haul road. This ditch appears to be a remnant of the shrimp ponds that were historically on this site. The ditch also appears to have been connected to another pond at one time, via a culvert on its east end; however, this culvert no longer appears to function. Vegetation consists of a shrub and subcanopy layer composed of saltbush, Florida privet, wax myrtle, winged sumac, sugarberry (Celtis laevigata), and Brazilian pepper. Understory vegetation is dominated by thickets of poison ivy and flamevine.

Wetland HardwoodForest (FL UCFCS 610)

This 0.04-acre wetland is located in the central portion of the proposed laydown area, south of the access road. The canopy layer is sparse and consists primarily of sugarberry and sabal palm. The subcanopy and shrub layers include saltbush, wax myrtle, Florida privet, and winged sumac. Understory vegetation is sparse and composed primarily of flamevine, with lesser amounts of bushy broomsedge and poison ivy.

Saltwater Marsh (FLUCFCS 642)

This wetland habitat is located adjacent to the northern and western boundaries of the proposed laydown area. Sparse canopy, where it exists, is dominated by red cedar and cabbage palms. The subcanopy is also sparse, consisting of black mangroves (Avicennia germinans) and Florida privet. Saltbush, marsh elder (Iva frutescens), christmasberry (Lycium carolinianum), and wax myrtle dominate the shrub layer, with lesser amounts of white mangrove (Laguncularia racemosa) and Brazilian pepper. Groundcover species include black needlerush (Juncus roemerianus), saltgrass (Distichlis spicata), saltwort (Batis maritima), sea purslane (Sesuvium portulacastrum), broomsedge, and bushy broomsedge.

The proposed laydown area construction activities have been designed so that adverse secondary impacts to this wetland are avoided by providing a minimum 15-ft, average of 25-ft, buffer between construction activities and this system.

Canals and Locks (FL UCFCS 816)

This is a 0.006-acre portion of shoreline of the man-made intake canal, located along the southwestern boundary, of the laydown area site. Vegetation along the man-made canal shoreline is

Golder Associates May 2009 -7- 093-89529 sparse and consists of upland species such as beggar ticks (Bidens pilosa) and an approximately 5-10 foot strip of wetland species such as saltwort, sea purslane and sea blite (Suaeda linearis).

According to the FEMA flood zone maps, the site occurs in a coastal high hazard zone, Zone VE, and is prone to inundation from tidal floods (Figure 6).

Soils

Two NRCS soil types were identified in the proposed south cooling tower area (Figure 4). These soil types are described below (USDA, 2006).

22- Quartzipsamments, 0 to 5 percent slopes

This is the dominant soil type on the proposed cooling tower laydown area. This soil is nearly level to gently sloping and has been reworked and shaped by earthmoving activities. Historically, many of these areas were sloughs, marshes, shallow ponds, or other areas of standing water that have been filled with sandy soil materials to match the level of the surrounding landscape, or higher. Depth to water table is typically greater than 80 inches, depending on the thickness of the fill material and drainage of the underlying soils. Permeability is also variable, but generally very rapid. Vegetation tolerant of very low fertility and droughty conditions is common.

38- Rock Outcrop - Homosassa-LacoocheeComplex

This soil type consists of limestone rock outcrop and Homosassa and Lacoochee soils that are common to tidal saltwater marshes and offshore islands along the Gulf Coast. These soils are flooded daily by high tides and/or periodically flooded by exceptional high tides and storm tides. Vegetation common to this soil type includes smooth cordgrass, marshhay cordgrass, seashore saltgrass, and other forage grasses and forbs.

3.2 Listed Species Assessment

Flora

Four listed plant species were identified by FNAI within 1 square mile of the project site (FNAI, Matrix Unit ID 21566, Appendix D). Of the four listed plants, the state classifies three as endangered and the remaining one as threatened. In addition, the USFWS classifies one of the four species as federally endangered.

Golder Associates May 2009 -8- 093-89529

A description of these species follows.

Cooley's Water Willow (Justiciacooleyi)

The USFWS and the FDACS list Cooley's water willow as endangered. This flowering perennial herb grows up to 16 inches tall and has erect, square, hairy stems with few branches. Cooley's water willow is found in mesic hardwood hammocks over limestone (FNAI, 2000). Due to limited quantity and disturbed nature of the preferred habitat located within the laydown area site, it is unlikely that this species is present.

Corkwood (Leitneriafloridana)

The FDACS lists corkwood as threatened. This deciduous shrub or small tree (up to 15 ft) typically occurs in colonies. The reddish stem contains small corky patches and conspicuous leaf scars. Corkwood leaves are alternate, with entire margins, clustered at the top of the stems; mature leaves are smooth above and softly hairy beneath. This plant occurs along edges of marshy openings and along small drainages in coastal hydric hammocks; occurs along fresh or tidal marshes; and is frequently associated with sawgrass (Cladiumjamaicense)and toothleaf (Stillingiasylvatica) (FNAI, 2000). Due to the lack of potential habitat on the laydown area site, it is unlikely that this species is present; however, this species may occur within the saltwater marsh adjacent to the project site.

Pinewood Dainties (Phyllanthusleibmannianus spp. platylepis)

The FDACS lists pinewood dainties as endangered. This flowering perennial herb has smooth, slender, unbranched stems. This plant grows 12 to 20 inches tall, rising from a blackish woody stem. Leaves are alternate, spirally arranged around the stem, widest above the middle with rounded or pointed tips, dark green above, pale green and conspicuously veined below, and sessile. This plant occurs in hardwood-palm hammocks, flatwoods, and Gulf hammocks with a high hydroperiod and fine-textured, highly drained soils of limestone (NatureServe Explorer, 2009). Due to limited quantity and disturbed nature of one of this species' preferred habitats on the laydown area site, it is unlikely that this plant is present.

Pinkroot (Spigelia loganoides)

The FDACS lists pinkroot as endangered. Pinkroot is a flowering perennial herb up to 8 inches tall, with several sparingly branched stems that grow from a slightly woody base. It is typically found in floodplain forests and upland and hydric hardwood hammocks over limestone (FNAI, 2000). Due to

Golder Associates May 2009 -9- 093-89529

limited quantity and disturbed nature of this species' preferred habitat on the laydown area site, it is unlikely to be present.

Fauna

The habitat types identified in the laydown area that serve as the principal wildlife habitat types include temperate hardwood forests, and wetland/aquatic areas such as streams and waterways and a small wetland hardwood forest. Habitats such as canals and locks and utilities are of relatively lower value to wildlife.

Based on habitat requirements and availability, Golder and FNAI identified a total of 19 listed wildlife species as being likely to occur or with a potential to occur within 1 square mile of the project area (FNAI, 2009). Of these 19 species, the USFWS lists 4 as threatened and 3 as endangered. The FFWCC lists 10 of the 19 species as species of special concern, 5 as endangered, and the remaining 4 as threatened. USFWS- and FFWCC-listed species are discussed in the following paragraphs. The bald eagle (Haliaeetus leucocephalus) is also included in the following discussion due to its protection under the Federal Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act, as well as Florida's Bald Eagle Management Plan.

Fish

Gulf Sturgeon (Acipenser oxyrinchus desotoi)

The USFWS lists the Gulf sturgeon as threatened, and the FFWCC lists it as a species of special concern. This large sturgeon, approximately 5 to 7.5 ft in length, forages in the Gulf of Mexico and associated estuaries. It spawns in most major coastal rivers in areas with limestone outcrops. Adults and subadults spend the three coldest months in the Gulf and the remainder of the year in rivers where spawning occurs (February to April) (FNAI, 2001). It is unlikely that the Gulf sturgeon is present within the project area.

Reptiles

Loggerhead (Caretta caretta)

Both the USFWS and the FFWCC list loggerheads as threatened. They inhabit marine coastal and oceanic waters, nesting on coastal sand beaches, often near the dune line. Juvenile turtles frequent

Golder Associates May 2009 -10- 093-89529 bays, inlets, and lagoons. Due to lack of preferred habitat, it is unlikely that the loggerhead is present within the project area.

Green Turtle (Chelonia mydas)

Both the USFWS and the FFWCC list the green turtle as endangered. Green turtles inhabit estuarine and marine coastal and oceanic waters, nesting on coastal sand beaches, often near the dune line. Juveniles frequent coastal bays, inlets, lagoons, and offshore worm reefs. Due to lack of preferred habitat, it is unlikely that the green turtle is present within the project area.

Eastern Indigo Snake (Drymarchon couperi)

Both the USFWS and the FFWCC list the eastern indigo snake as threatened. These snakes can occur within a broad range of suitable habitats, from scrub and sandhill to wet prairies. In its northern range, it is often commensal with the gopher tortoise, using the tortoises' burrows for shelter during the winter (FNAI, 2001). Due to the lack of preferred habitat within the project area, it is unlikely that the eastern indigo snake is present.

Gopher Tortoise (Gopheruspolyphemus)

The FFWCC currently lists the gopher tortoise as threatened. Gopher tortoises are commonly found in dry upland habitats, such as sandhills, scrub, xeric oak hammock, and dry pine flatwoods. They are also found in pastures and old fields (FNAI, 2001). Due to the lack of preferred habitat within the project area, it is unlikely that the gopher tortoise is present.

Birds

Scott's Seaside Sparrow (Ammodramus maritimuspeninsulae)

The FFWCC lists Scott's seaside sparrow as a species of special concern. Sparrows present along the Gulf coast inhabit areas dominated by extensive stands of black needlerush, with smooth cordgrass and scattered areas of saltgrass. Due to the presence of saltwater marshes adjacent to the project site, there is a potential that this species is present nearby.

Piping Plover (Charadriusmelodus)

Both the USFWS and the FFWCC list the piping plover as threatened. They inhabit open sandy beaches, as well as tidal mudflats and sandflats along the coast (FNAI, 2001). In 2001, FNAI

Golder Associates May 2009 -11- 093-89529 identified one adult foraging along the intake canal southwest of the site (Appendix D) (FNAI, 2009). Due to the presence of saltwater marshes adjacent to the laydown area, there is a potential that this species is present nearby.

Marian's Marsh Wren (Cistothoruspalustris marianae)

The FFWCC lists Marian's marsh wren as a species of special concern. They inhabit tidal marshes dominated by black needlerush on the Gulf coast (FNAI, 2001). Due to the presence of saltwater marshes adjacent to the laydown area, there is a potential that this species is present nearby.

Snowy Egret (Egrettathula)

The FFWCC lists the snowy egret as a species of special concern. It is widely distributed in Florida in both freshwater and coastal wetlands, as well as surface waters (FNAI, 2001). It is likely to forage in the saltwater marsh and surface waters adjacent to the project area.

Tricolored Heron (Egretta tricolor)

The FFWCC lists the tricolored heron as a species of special concern. It inhabits a variety of wetland and surface water habitats, such as ditches, pond and lake edges, and coastal areas (FNAI, 2001). It is likely to forage in the saltwater marsh and surface waters adjacent to the project area.

White Ibis (Eudocimus albus)

The FFWCC lists the white ibis as a species of special concern. It inhabits a variety of wetland habitats, including freshwater and brackish marshes, salt flats, forested wetlands, wet prairies, swales, and man-made ditches (FNAI, 2001). It is likely to forage in the saltwater marsh and surface waters adjacent to the project area.

American Oystercatcher (Haematopuspalliatus)

The FFWCC lists the American oystercatcher as a species of special concern. Oystercatchers typically require large areas of beach, sandbar, mud flat, and shellfish beds for foraging, and are more common on the Gulf coast (FNAI, 2001). In 1987, FNAI identified eight pairs of oystercatchers atop a spoil island west of the site (Appendix D) (FNAI, 2009). Due to the presence of mud flats/saltwater marshes adjacent to the project site, there is a potential for these birds to be present nearby.

Golder Associates May 2009 -12- 093-89529

Bald Eagle (Haliaeetusleucocephalus)

Although the bald eagle is not currently classified by the USFWS or the FFWCC as threatened or endangered, it is protected under the Federal Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act, as well as Florida's Bald Eagle Management Plan. Bald eagles typically inhabit areas close to coastal areas, bays, rivers, lakes, or other bodies of water that provide concentrations of food sources (FNAI, 2001).

Two active bald eagle nests are known to occur within approximately 1 mile of the project site. Nest CI004 is located approximately 1 mile northeast of the site and was last active in 2008; nest CI042 is located approximately 0.7 mile southeast of the site and was last listed as active in 2007 (FFWCC, 2009) (Figure 7). In addition one inactive bald eagle nest (CIO12) was identified approximately 1.5 miles southeast of the project site. This nest was last reported active in 1991. Impacts to bald eagles may be avoided through adherence to the management plan guidelines of 330- to 660-ft construction setback from any active nests.

Wood Stork (Mycteria americana)

Both the USFWS and the FFWCC list the wood stork as endangered. Wood storks prefer nesting in cypress swamps and mixed forested wetlands, and they forage mainly in shallow water in freshwater marshes, swamps, lagoons, ponds, tidal creeks, flooded pastures, and ditches (FNAI, 2001). Due to lack of preferred nesting habitat, it is unlikely that this species nests nearby; however, it may occasionally forage adjacent to the project site.

Roseate Spoonbill (Plataleaajaja)

The FFWCC lists the roseate spoonbill as a species of special concern. It forages in shallow water of variable salinity, including marine tidal flats and ponds, coastal marshes, mangrove-dominated inlets and pools, and freshwater sloughs and marshes (FNAI, 2001). Therefore, it can reasonably be expected to found foraging within the saltwater marsh adjacent to the laydown area project site.

Black Skimmer (Rynchops niger)

The FFWCC lists the black skimmer as a species of special concern. They inhabit coastal waters, including beaches, bays, estuaries, sandbars, and tidal creeks (FNAI, 2001). There is a potential that the black skimmer utilizes the saltwater marsh adjacent to the laydown area project site.

Golder Associates May 2009 -13- 093-89529

Least Tern (Sterna antillarum)

The FFWCC lists the least tern as threatened. They are present in coastal areas throughout Florida, including beaches, lagoons, bays, and estuaries (FNAI, 2001). In 1987, FNAI identified six pairs of terns via vocalization atop a spoil island west of the site (Appendix D) (FNAI, 2009). There is a potential that they are present in the saltwater marsh adjacent to the project site.

Mammals

Florida Mouse (Podomysfloridanus)

The FFWCC lists the Florida mouse as a species of special concern. They prefer xeric upland habitats with sandy soils, such as scrub, sandhills, and ruderal sites, and they often inhabit burrows of the gopher tortoise (FNAI, 2001). Due to the lack of gopher tortoise habitat on the project site, it is unlikely that the Florida mouse is present.

Manatee (Trichechus manatus)

Both the USFWS and the FFWCC list the manatee as endangered. Manatees inhabit bays, rivers, and coastal waters (FNAI, 2001). There is a designated manatee aggregation site approximately 0.18 mile northeast of the proposed laydown area, within the discharge canal of the Crystal River Energy Complex. According to the FNAI report, up to five manatees use this area for short periods of cool weather, mostly during the spring when manatees disperse northward from Crystal River (Appendix D) (FNAI, 2009). Adverse impacts are not anticipated to manatees as a result of the construction laydown area project.

Florida Black Bear (Ursus americanusfloridanus)

The FFWCC lists the Florida black bear as threatened. They prefer large upland forests and large swamps (FNAI, 2001). It is not likely that the Florida black bear is present within the project site due to the absence of large, contiguous tracts of mixed forested wetlands and mixed hardwood-conifer forests.

Golder project scientists conducted a general listed species survey on March 17, 2009. Afterward, Golder compiled a complete list of all wildlife species observed within and adjacent to the project area; it is provided in the table below.

No listed floral or faunal species were observed on or adjacent to the site. In addition, neither bald eagles nor their nests were encountered. According to the FFWCC database, the closest active bald eagle nest is located well outside the 660-ft recommended bald eagle nest buffer zone (± 0.7 mile southeast of the project area) (Figure 7).

3.3 Wetland Functional Assessment

A forested wetland (WL B - 0.04 acre), a remnant shrimp pond/ditch consisting of two portions (SW I - 0.04 acre + 0.03 acre), and a man-made canal shoreline (SW II - 0.006 acre), were identified on the proposed laydown area site. All of these systems combined comprise less than 0.50 acre of impacts (0.116 acre total) and appear to provide marginal value and function to fish and wildlife. UMAM evaluations were conducted for all three systems and produced functional losses of 0.017-acre credit for the forested wetland, 0.003-acre credit for the intake canal shoreline, and 0.026-acre credit for the remnant shrimp pond/ditch for a total of 0.046-acre credit (Appendix E).

The lost wetland functions will be replaced through the purchase of 0.05 mitigation credit from an agency-approved mitigation bank as discussed below.

Golder Associates May 2009 -15- 093-89529

The laydown area site is within the service area of the SWFWMD-permitted Upper Coastal Mitigation Bank (UCMB). The UCMB is a 148.76-acre mitigation bank located at the headwaters of the Homosassa River, approximately 600 ft south of the Homosassa Wildlife Park, and approximately 1,700 ft north of the Withlacoochee State Forest in the town of Homosassa, Citrus County, Florida (Figure 8). UCMB offers state mitigation credits for forested and non-forested wetlands. Purchase of credits from the UCMB would promote wetland restoration and conservation efforts within the southwest Florida region to offset the loss of wetland functions attributed to construction of the project.

Federal credits are not currently available at the UCMB; however, according to the UCMB manager, the USACE is in the process of permitting the new phase of the bank (Earth Balance, May 2009). Upon receipt of the approved jurisdictional determination, Golder will, if necessary, prepare a detailed mitigation proposal and submit it to the USACE.

Golder Associates May 2009 -16- 093-89529

4.0 AVOIDANCE AND MINIMIZATION

Efforts to eliminate and/or reduce impacts to wetlands resulted in redesign of the original project layout to avoid a tidally influenced wetland system associated with the northern and western portions of the site.

The original design utilized the entire cooling tower laydown area site, without a wetland buffer zone, which would result in secondary impacts to the saltwater marsh (FLUCFCS 642) that borders the site to the north and west. Project refinement provided for the use of a minimum 15-ft buffer zone, with an average of 25 fi, eliminating these secondary impacts. Therefore, wetland impacts were reduced through utilization of previously disturbed uplands (FLUCFCS 425 and 830), in addition to a small disturbed wetland (FLUCFCS 610) and other surface waters (FLUCFCS 510 and 816), to the greatest extent practicable.

Explain: SW II is the bank of the intake canal for the adjacent Crystal River Energy Complex and is immediately connected to the Gulf of Mexico. It is subject to the ebb and flow of the tide and may be susceptible for use to transport interstate commerce.

B. CWA SECTION 404 DETERMINATION OF JURISDICTION.

There Pick List "waters of the U.S." within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 328) in the review area. [Required]

1. Waters of the U.S. a. Indicate presence of waters of U.S. in review area (check all that apply): 0] TNWs, including territorial seas 0] Wetlands adjacent to TNWs El Relatively permanent waters 2 (RPWs) that flow directly or indirectly into TNWs 0] Non-RPWs that flow directly or indirectly into TNWs El Wetlands directly abutting RPWs that flow directly or indirectly into TNWs E] Wetlands adjacent to but not directly abutting RPWs that flow directly or indirectly into TNWs E] Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs E] Impoundments of jurisdictional waters El Isolated (interstate or intrastate) waters, including isolated wetlands

c. Limits (boundaries) of jurisdiction based on: 1987 Delineation Manual Elevation of established OHWM (if known):

3 2. Non-regulated waters/wetlands (check if applicable): El Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain:

Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS

A. TNWs AND WETLANDS ADJACENT TO TNWs

The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below.

1. TNW Identify TNW: Surface Water II intake canal bank

Summarize rationale supporting determination: The Gulf of Mexico is a TNW and it supports interstate commerce. The intake canal bank (SW 1I) is a TNW that is immediately connected to the Gulf of Mexico, a TNW. Both the Crystal River Energy Complex intake canal and the Gulf of Mexico do or may support interstate commerce and are subject to the ebb and flow of the tide.

2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": Wetland B is adjacent to waters of the Gulf of Mexico.

B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):

This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met.

The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4.

A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law.

If the waterbody 4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below.

1. Characteristics of non-TNWs that flow directly or indirectly into TNW

(i) General Area Conditions: Watershed size: 933 qiuare miles Drainage area: 5.026Cacres Average annual rainfall: inches Average annual snowfall: inches

3. Characteristics of all wetlands adjacent to the tributary (if any) All wetland(s) being considered in the cumulative analysis: IT Approximately ( 0.04 ) acres in total are being considered in the cumulative analysis. For each wetland, specify the following:

Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) N 0.04

Summarize overall biological, chemical and physical functions being performed: The subject wetland "B" contains very poor hydric soil indicators and hydrology. Vegetation is not typical of a healthy wetland and contains both upland and wetland plant species. It is infested with saltbush, flamevine and poison ivy. The wetland is jurisdictional because it is adjacent to the Gulf of Mexico TNW, not because it is adjacent to the upland cut ditch which appears to be a remnant from the historic shrimp farm facility on site many years ago. The ditch does not maintain perennial or seasonal flows and does not appear to support any fish or crustaceans which could be foraged upon by wading birds. The ditch and wetland are both jurisdictional because of their sheer proximity to the Gulf of Mexico TNW and have the potential to carry nutrients, pollutants or flood waters to the Gulf of Mexico.

C. SIGNIFICANT NEXUS DETERMINATION

A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is notappropriate to determine significant nexus based solely on any.specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus.

Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: " Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? * Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? * Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? * Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW?

Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below:

1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: .

2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: The subject surface water ditch SW I and its adjacent Wetland B are in very close proximity to the adjacent Gulf of Mexico TNW. The subject non-RPW ditch together with the adjacent on-site wetland have the potential to carry nutrients, pollutants or flood waters to the Gulf of Mexico TNW. They do not appear to have sufficient hydrology to support fish, crustaceans or other aquatic macro-organisms and do not provide any significant foraging value for federally listed wading birds such as the wood stork or other State listed wading birds. They also lack the vegetative structure to support nesting or roosting wading birds and federally listed wildlife species. The existing sugarberry trees generally have a <1" DBH and are less than 8' tall. Wetland B is overgrown with saltbush, flamevine and poison ivy.

3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section Ill.D: .

Dear Ms. Ahrens,

Thank you for your request for information from the Florida Natural Areas Inventory (FNAI). We have compiled the following information for your project area.

Date Received: March 18, 2009 Location: Citrus County

Element Occurrences A search of our maps and database indicates that currently we have several Element Occurrences mapped within the vicinity of the study area (see enclosed map and element occurrence table). Please be advised that a lack of element occurrences in the FNAI database is not a sufficient indication of the absence of rare or endangered species on a site.

The Element Occurrencesdata layer includes occurrencesof rare species and natural communities. The map legend indicates that some element occurrences occur in the general vicinity of the label point. This may be due to lack of precision of the source data, or an element that occurs over an extended area (such as a wide rangingspecies or large natural community). For animals and plants, Element Occurrences generally refer to more than a casual sighting; they usually indicate a viable population of the species. Note that some element occurrences represent historicallydocumented observationswhich may no longer be extant.

Likely and Potential Rare Species In addition to documented occurrences, other rare species and natural communities may be identified on or near the site based on habitat models and species range models (see enclosed Biodiversity Matrix Report). These species should be taken into consideration in field surveys, land management, and impact avoidance and mitigation.

FNAI habitatmodels indicate areas, which based on land cover type, offer suitable habitatfor one or more rare species that is known to occur in the vicinity. Habitat models have been developed for approximately 300 of the rarestspecies tracked by the Inventory, including all federally listed species.

FNAI species range models indicate areas that are within the known or predicted range of a species, based on climate variables,soils, vegetation, and/orslope. Species range models have J6),-'' been developed for approximately 340 species, including all federally listed species.

Land Acquisition Projects This site appears to be located within the Florida Springs Coastal Greenway Florida Forever BOT Project, which is part of the State of Florida's Conservation and Recreation Lands land acquisition program. A description of this project is enclosed. For more information on this Florida Forever Project, contact the Florida Department of Environmental Protection, Division of State Lands. FloridaForever Board of Trustees (BOT) projects are proposed and acquiredthrough the Florida Departmentof Environmental Protection,Division of State Lands. The state has no regulatory authority over these lands until they are purchased.

The Inventory always recommends that professionals familiar with Florida's flora and fauna should conduct a site-specific survey to determine the current presence or absence of rare, threatened, or endangered species. Please visit www.fnai.org/trackinglist.cfm for county or statewide element occurrence distributions and links to more element information.

The database maintained by the Florida Natural Areas Inventory is the single most comprehensive source of information available on the locations of rare species and other significant ecological resources. However, the data are not always based on comprehensive or site-specific field surveys. Therefore, this information should not be regarded as a final statement on the biological resources of the site being considered, nor should it be substituted for on-site surveys. Inventory data are designed for the purposes of conservation planning and scientific research, and are not intended for use as the primary criteria for regulatory decisions.

Information provided by this database may not be published without prior written notification to the Florida Natural Areas Inventory, and the Inventory must be credited as an information source in these publications. FNAI data may not be resold for profit.

Thank you for your use of FNAI services. If I can be of further assistance, please give me a call at (850) 224-8207.

GLOBAL AND STATE RANKS

Florida Natural Areas Inventory (FNAI) defines an element as any rare or exemplary component of the natural environment, such as a species, natural community, bird rookery, spring, sinkhole, cave, or other ecological feature. FNAI assigns two ranks to each element found in Florida: the global rank, which is based on an element's worldwide status, and the state rank, which is based on the status of the element within Florida. Element ranks are based on many factors, including estimated number of occurrences, estimated abundance (for species and populations) or area (for natural communities), estimated number of adequately protected occurrences, range, threats, and ecological fragility.

GLOBAL RANK DEFINITIONS GI Critically imperiled globally because of extreme rarity (5 or fewer occurrences or less than 1000 individuals) or because of extreme vulnerability to extinction due to some natural or man-made factor. G2 Imperiled globally because of rarity (6 to 20 occurrences or less than 3000 individuals) or because of vulnerability to extinction due to some natural or man-made factor. G3 Either very rare and local throughout its range (21-100 occurrences or less than 10,0000 individuals) or found locally in a restricted range or vulnerable to extinction from other factors. G4 Apparently secure globally (may be rare in parts of range). G5 Demonstrably secure globally. G7#? Tentative rank (e.g., G2?) G#G# Range of rank; insufficient data to assign specific global rank (e.g., G2G3) G#T# Rank of a taxonomic subgroup such as a subspecies or variety; the G portion of the rank refers to the entire species and the T portion refers to the specific subgroup; numbers have same definition as above (e.g., G3TI) G#Q Rank of questionable species - ranked as species but questionable whether it is species or subspecies; numbers have same definition as above (e.g., G2Q) G#T#Q Same as above, but validity as subspecies or variety is questioned. GH Of historical occurrence throughout its range, may be rediscovered (e.g., ivory-billed woodpecker) GNA Ranking is not applicable because element is not a suitable target for conservation (e.g. as for hybrid species) GNR Not yet ranked (temporary) GNRTNR Neither the full species nor the taxonomic subgroup has yet been ranked (temporary) GX Believed to be extinct throughout range GXC Extirpated from the wild but still known from captivity/cultivation GU Unrankable. Due to lack of information, no rank or range can be assigned (e.g., GUT2).

STATE RANK DEFINITIONS

Definition parallels global element rank: substitute "S" for "G" in above global ranks, and "in Florida" for "globally" in above global rank definitions.

FEDERAL AND STATE LEGAL STATUSES (U.S. Fish and Wildlife Service - USFWS) PROVIDED BY FNAI FOR INFORMATION ONLY.

For official definitions and lists of protected species, consult the relevant state or federal agency.

FEDERAL LEGAL STATUS

Definitions derived from U.S. Endangered Species Act of 1973, Sec. 3. Note that the federal status given by FNAI refers only to Florida populations and that federal status may differ elsewhere.

LE Listed as Endangered Species in the List of Endangered and Threatened Wildlife and Plants under the provisions of the Endangered Species Act. Defined as any species which is in danger of extinction throughout all or a significant portion of its range. LE,XN A non essential experimental population of a species otherwise Listed as an Endangered Species in the List of Endangered and Threatened Wildlife and Plants. LE,XN for Grus americana (Whooping crane), Federally listed as XN (Non essential experimental population) refers to the Florida experimental population only. Federal listing elsewhere for Grus americana is LE. PE Proposed for addition to the List of Endangered and Threatened Wildlife and Plants as Endangered Species. LT Listed as Threatened Species, defined as any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. LT,PDL Species currently listed Threatened but has been proposed for delisting. PT Proposed for listing as Threatened Species. C Candidate Species for addition to the list of Endangered and Threatened Wildlife and Plants, Category 1. Federal listing agencies have sufficient information on biological vulnerability and threats to support proposing to list the species as Endangered or Threatened. SAT Threatened due to similarity of appearance to a threatened species. SC Species of Concern, species is not currently listed but is of management concern to USFWS. N Not currently listed, nor currently being considered for addition to the List of Endangered and Threatened Wildlife and Plants.

FLORIDA LEGAL STATUSES (Florida Fish and Wildlife Conservation Commission - FFWCC/ Florida Department of Agriculture and Consumer Services - FDACS)

Animals: Definitions derived from "Florida's Endangered Species and Species of Special Concern, Official Lists" published by Florida Fish and Wildlife Conservation Commission - FFWCC, 1 August 1997, and subsequent updates.

LE Listed as Endangered Species by the FFWCC. Defined as a species, subspecies, or isolated population which is so rare or depleted in number or so restricted in range of habitat due to any man-made or natural factors that it is in immediate danger of extinction or extirpation from the state, or which may attain such a status within the immediate future. LT Listed as Threatened Species by the FFWCC. Defined as a species, subspecies, or isolated population which is acutely vulnerable to environmental alteration, declining in number at a rapid rate, or whose range or habitat is decreasing in area at a rapid rate and as a consequence is destined or very likely to become an endangered species within the foreseeable future. LT* Indicates that a species has LT status only in selected portions of its range in Florida. LT* for Ursus amcricanus floridanus (Florida black bear) indicates that LT status does not apply in Baker and Columbia counties and in the Apalachicola National Forest. LT* for Neovison vison pop. I (Southern mink, South Florida population) state listed as Threatened refers to the Everglades population only (Note: species formerly listed as Mustela vison mink pop. 1. Also, priorly listed as Mustela evergladensis).

LS Listed as Species of Special Concern by the FFWCC, defined as a population which warrants special protection, recognition, or consideration because it has an inherent significant vulnerability to habitat modification,

7cracnj 'F[orida'S iodi'versi& FloridaNatural Areas Inventory Rank Explanations February,2007

environmental alteration, human disturbance, or substantial human exploitation which, in the foreseeable future, may result in its becoming a threatened species. LS* Indicates that a species has LS status only in selected portions of its range in Florida. LS* for Pandion haliactus (Osprey) state listed as LS (Species of Special Concern) in Monroe County only.

PE Proposed for listing as Endangered. PT Proposed for listing as Threatened. PS Proposed for listing as a Species of Special Concern. N Not currently listed, nor currently being considered for listing.

Plants: Definitions derived from Sections 581.011 and 581.185(2), Florida Statutes, and the Preservation of Native Flora of Florida Act, 5B-40.001. FNAI does not track all state-regulated plant species; for a complete list of state-regulated plant species, call Florida Division of Plant Industry, 352-372-3505 or please visit: http://DOACS.State.FL.US/PI/Images/Rule05b.pdf

LE Listed as Endangered Plants in the Preservation of Native Flora of Florida Act. Defined as species of plants native to the state that are in imminent danger of extinction within the state, the survival of which is unlikely if the causes of a decline in the number of plants continue, and includes all species determined to be endangered or threatened pursuant to the Federal Endangered Species Act of 1973, as amended. PE Proposed by the FDACS for listing as Endangered Plants. LT Listed as Threatened Plants in the Preservation of Native Flora of Florida Act. Defined as species native to the state that are in rapid decline in the number of plants within the state, but which have not so decreased in such number as to cause them to be endangered. LT* indicates that a species has LT status only in selected portions of its range in Florida. PT Proposed by the FDACS for listing as Threatened Plants. N Not currently listed, nor currently being considered for listing.
