There is currently a small pile-supported dock located within Shallow Bay on the north side of the island. The bay is very shallow and vessels accessing the dock have damaged the shallow seagrass beds within the bay. At one time, there had been a concrete bulkhead at the shoreline with a small floating dock. The previous owner submitted an application for the existing dock which was approved by DPNR's Division of Coastal 2 EFTA00802727 Zone Management but was not approved by the U.S. Army Corps of Engineers due to objections by National Marine Fisheries because of the shallowness of the bay. The dock was constructed by the previous owner despite not receiving the federal permit and notices were issued by the USACE requesting the removal of the unpermitted structure. The dock however was never removed. The applicant understands the issues with the existing dock and is proposing to remove the dock as soon as another dock is constructed and usable. A detailed study was done around the entire island to determine suitable locations for dock location. All ESA listed corals were located and docks and barge landings were designed to avoid these corals. A temporary barge landing is being proposed on the northwestern facing beach. This site is to the west of the salt pond and the associated wetlands. This a shoreline ramp which is 25 feet (ft) wide and 40ft in length extends to the Mean Water Line. The landing is free of both coral and seagrass colonization. The landing is excellent for short term transfer of material or equipment. The site is well protected from normal wave action but is periodically impacted by wave action from ferries which travel through current cut between Great St. James and St. Thomas. The wakes from these vessels make it an unattractive site for mooring a barge for any length of time at the site. This landing can be quickly constructed and utilized while the combination dock and barge landing on the southeastern side of the island is constructed. The western dock is proposed on the northern end of Christmas Cove. Historically there was a dock in this location and there are still old concrete piles lying in the shallows of this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft from mean low water (MLW) and 193ft from mean high water (MHW). The dock extends beyond the nearshore hardbottom to a depth of 15ft out in the uncolonized sand to allow for safe dockage for deeper vessels. The southern dock is located off the point closest to Little St. James. The dock is "L" shaped and is 20ft wide (to allow for barge landing) and 150ft in length extending 141ft from MLW and I48ft from MHW, the "L" then turns east and extends 100ft by 20ft. A wave attenuating/reef creating system is proposed beneath the dock which will allow for more protected docking inside the dock when seas from the south are rough. The dock has 9ft of water depth of the southern end and 711 to 8ft on the inside of the "L". The dock has been designed so that barges can approach and land on the end of the dock while vessels can dock along the "L". After the hurricane Irma in 2017 the owner of the Great St. James assisted many of his employees and their families who had lost their homes and housed people on the island. In order to bring in emergency supplies, two small barge ramps were created near the locations of both proposed docks; one in Christmas Cove and one off the closest point to Little St. James. Both consisted of coral rubble and boulders pushed out into the water approximately 10ft. and both were 15ft. wide. These were noticed by the USACE during 3 EFTA00802728 aerial surveillance and the USACE requested the removal of the structures as well as the removal of some fill material which was deposited into the fringing wetland area while creating access to the southern emergency ramp. The southern ramp has been removed and the fill has been removed from the wetland area and white mangrove seeds have been being spread in the wetland and seedlings are beginning to sprout. The applicant is requesting that he be allowed to keep the emergency ramp in Christmas Cove until such time a permit is granted for the proposed barge ramp. This will facilitate the bringing of materials and supplies to the island until such time a permanent ramp can be built. 4.00 STATEMENT OF OBJECTIVES SOUGHT BY THE PROPOSED PROJECT Great St. Jim, LLC is proposing to construct a temporary barge landing and an access dock on the western side of the island to be used for worker and guest access to the island and a combination barge landing/dock on the southeast side of the island on the point closest to Little St. James. The existing dock in Shallow Bay will be removed as soon as one of the docks is functional. The applicant is requesting to keep the emergency rubble ramp in Christmas Cove until such time that the proposed barge landing can be permitted and constructed. 5.0 SUMMARY OF PROPOSED ACTIVITY Great St. Jim, LLC is seeking to construct two docks, one of which is a combination dock/barge landing, and a temporary barge landing to provide access to Great St. James Island. A detailed study was done around the entire island to determine suitable locations for the dock locations and the sites with the least environmental impact were chosen. A temporary barge landing is being proposed on the northwestern facing beach. This site is to the west of the salt pond and the associated wetlands. This a shoreline ramp which is 25 feet (ft) wide and 40ft in length extends to the Mean Water Line. Two bollards will be placed to either side of the ramp and two moorings will be installed 75ft offshore on either side of the ramp in just over 7ft of water depth. The mooring will be installed using helix anchors and will use floating lines will be used to avoid seafloor disturbance when the moorings are not in use. The landing is free of both coral and seagrass colonization. The landing is excellent for short term pick up and drop off of material or equipment. The site is well protected from normal wave action but is periodically impacted by wave action from ferries which travel through current cut between Great St. James and St. Thomas. The wakes from these vessels make it an unattractive site for mooring a barge for any length of time at the site. This landing can be quickly constructed and utilized while the combination dock and barge landing on the southeastern side of the island is constructed. 4 EFTA00802729 The western dock is proposed on the northern end of Christmas Cove. Historically there was a dock in this location and there are still old concrete piles lying in the shallows of this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft from mean low water (MLW) and 193ft from mean high water (MHW). The dock will connect to an access slab 12ft long and 2' thick. All the ESA listed coral species within the area were located and the dock footprint avoids all ESA listed species. The dock extends beyond the nearshore hardbottom to a depth of 15ft out in the uncolonized sand to allow for safe dockage for deeper vessels. The southern dock is located off the point closest to Little St. James. Again, all of the ESA corals were located, and the dock was designed to avoid these corals. The dock is shaped and is 20ft wide (to allow for barge landing) and 150ft in length extending 141ft from MLW and 148ft from MHW, the "L" then turns east and extends 10011 by 20ft. A wave attenuating/reef creating system is proposed beneath the dock which will allow for more protected docking inside the dock when seas from the south are rough. The dock has 9ft of water depth of the southern end and 7ft to 8ft on the inside of the "L". The dock has been designed so that barges can approach and land on the end of the dock while vessels can dock along the "L". The existing dock in the shallow northern bay will be removed as soon as one of the other two docks is functional. The dock will have the decking removed, and then the stringers and pile caps will be disassembled. This will all be done by workers from the shore. Once only the piles remain, a shallow draft barge will come into the bay and pull the piles out. If for some reason the piles cannot be pulled they will be cut off by commercial divers at the mudline. As soon as the proposed barge landing can be constructed the applicant will remove the emergency ramp from Christmas Cove. This will be done from the shoreline using a backhoe which will pull the cobble back on to the beach and spread it out along the back beach. The larger riprap boulders will be taken inland to use in landscaping. 5.0Ia Purpose of Project The purpose of this application is to provide access to the island of Great St. James. Great St. Jim, LLC is proposing to construct a temporary barge landing to be used during the construction of the other docks, an access dock on the western side of the island to be used for worker and guest access to the island, and a combination barge landing/dock on the southeast side of the island on the point closest to Little St. James. The existing dock in Shallow Bay and emergency ramp in Christmas Cove will be removed as soon as one of the docks and proposed barge ramp is functional. 5 EFTA00802730 5.01b Presence and Location of any Critical Areas and Possible Trouble Spots The island of Great St. James is within the Vessup Bay/ East End Red Hook Area of Particular Concern (APC) (Figure 5.01.1).

The regulations for the St. James are as follows: St. James Marine Reserve and Wildlife Sanctuary Subchapter 96, Section 96-3 Prohibited Activities within the St. James MRWS: • It is unlawful to remove any marine or other wildlife without a permit or specific authorization from the Commissioner Subchapter Permitted Activities within the St. James MRWS: 96, Section 96-4 Acts permitted, provided a permit is first obtained from the Commissioner: • Scientific collecting in support of and for use in a research project with an approved protocol • The use of castnet with a minimum square mesh size of X inch to capture baitfish (fry) within 50 feet of the shoreline, except for Cow and Calf rocks • Fishing with hook and line 7 EFTA00802732 The marine habitats around Great St. James have abundant coral and seagrass resources. There are numerous ESA listed corals species near the proposed dock locations. Acropora palmata, Acropora. cervicornis, Orbicella annularis, Orbicella franksi and Orbicella faveolata as well as Dendrogyra cylindrus are found off all the beach from which the proposed docks and barge landings are planned. At the northern temporary barge landing site, these corals are located primarily to the west in an area of coral boulders and coral rubble. However, there are several small A. palmata and several 0. annularis located on the shoreline cobble which extends out to a depth of 6.5ft. The presence of these species as well as several non-ESA listed Porites astreoides has dictated the location of the ramp. The proposed temporary barge landing position avoids all coral and seagrass resources. Location of the western dock has a cobble beach between two areas of emergent bedrock and boulders. A. paknata occur on the emergent bedrock to the north. Offshore the seafloor quickly gives way to exposed pavement. There is a long linear depression right offshore and an old piling lies within this area. The fractured pavement then extends to approximately 11.5ft of depth over the next 100ft heading offshore. The area has some widely-scattered boulders and patchy coral colonization. There are scattered ESA corals including Orbicella and Dendrogyra. During the first survey, there was a very large A. palinata colony immediately seaward of where the old piling lay near shore. However, upon the next visit by the island it was noted that an old boat was tied nearshore apparently attached to the old piling. During a dive, several weeks later it was noted that the boat was gone and the large A. cervicornis had been badly broken. The location of all the ESA species has dictated the location of the dock. Approximately 75 corals will require relocation to minimize impact, but no listed corals will need relocation. The southern dock also extends from a cobble beach which gives way to rock pavement and has emergent bedrock and boulders on either side of the beach. There are Acropora colonies to the east and farther to the south on the bedrock and boulders. There are Orbicella and Dendrogyra within the embayment and their locations have dictated the location of the dock. The dock avoids all ESA listed corals but will require the relocation of approximately 75 corals. This southern dock will include a combination wave attenuator and reef building system. A mitigation plan has been prepared and is found in Appendix B. Because of the rock occurring in the area, some of the pilings may require socketing and if this is required special water quality measures will be taken. If at all possible a vibra- hammer will be used to drive the piles. A water quality monitoring program has been proposed and the plan is found in Appendix C. The area is known habitat to protect sea turtles and marine mammals and as such NOAA's Sea Turtle and Smalltooth Sawfish Construction Conditions will be followed as well as NOAA's Vessel Strike Avoidance Measures and Reporting for Mariners. 8 EFTA00802733 The property contains 6 salt ponds. The wetland around the salt ponds have been delineated and the delineations were approved by the U.S. ACOE during a previous application for development of the island. This delineation is more than 5 years old, but no wetland disturbance will occur as a result of this project. The island is known to be habitat to the St. Thomas Tree Boa that is a listed rare and endangered species. The boa as well as another species of snake have been seen during the field studies. There will be special corridors and preservation areas set aside on the island for these species. The access ways to the western and southern docks already exist, but the branch that will need to be developed to the temporary barge landing will be cleared by hand to limit impacts to the tree boas. A tree boa mitigation plan is found in Appendix D. Both emergency barge ramps consisted of cobble and boulders pushed out from the shoreline to create landings so that the barge would have sufficient water depth to land the supplies. Both ramps were pushed out over the uncolonized coral rubble and neither extend deep enough to encounter coral resources. No turbidity impacts were noted during the survey of the ramps. The southern ramp has since been removed. 5.OIc Method of Construction The temporary barge ramp will be the first feature constructed. The landing slab will be framed and poured from shore and the bollards will be installed near the shoreline. The cobble will be excavated with a small machine and silt fencing will be placed seaward off all excavation prior to any work. Divers utilizing a small boat will install the offshore moorings. As soon as this ramp is in the emergency barge ramp will be removed. The emergency barge ramp will be removed by backhoe from the shoreline. The cobble will be pulled in and spread on the back beach. The riprap will be taken inland to use in landscaping. The western and southern docks will both be constructed from a barge. A vibratory hammer will be used to drive all the piles if the hardness of the rock allows. If the rock proves to be too hard, the piles will be socketed, placed, and grouted in. All corals will be transplanted out of the footprint and area of impact prior to the start of construction and all turbidity control will be installed prior to any in-water work that day. If rocketing is required, seafloor length curtains will be used and monitored and not removed until water quality within the curtains has fallen to acceptable limits. All corals within the curtain limits will be removed to prevent damage by settling sediments. Once the pilings have been placed, re-enforcing steel will be placed, and concrete poured. Turbidity controls will be installed, and water quality monitoring will occur during all concrete pouring. Once the piles are completed the pile caps and decking will be placed. 1O EFTA00802734 Access slabs will be constructed from shore and silt fencing will be placed seaward of all excavations. The existing dock will be removed as soon as one of the access docks is functional. The decking and pile caps will be removed from shore. The pilings will be pulled by a small barge and if the pilings proved to hard to pull they will be cut off at mudline. 5.0Id Provisions to Limit Site Disturbance The dock locations have been located to minimize impact on the marine environment by avoiding all ESA listed corals and seagrass beds. Corals which cannot be avoided will be relocated out of the footprint and potential area of impact and turbidity control and water quality monitoring will be implemented. The branch of the road to the temporary barge landing will be first cleared by hand to minimize impact to the VI Tree Boa. A Tree Boa protection plan is found in Appendix D. 5.00e Sedimentation Control Methods to be Implemented. Silt fencing will be placed seaward of all upland excavation and construction. Turbidity bathers will be installed around all areas of in-work, including pile driving and concrete pouring overwater. If pile socketing is required two rows of turbidity bathers will be installed and these curtains will be seafloor length. These curtains will be maintained until the interior water quality has fallen to acceptable levels. 5.00f Schedule for Construction Activities and Implementation of Sediment Control Measures Silt fencing will be installed prior to any upland excavation and maintained throughout construction. All construction will be occurring in cobble areas without vegetation, so fencing will be maintained until such time no exposed soil is within the area. Silt fencing will be installed during the new access road clearing and maintained until such time the roadway is stabilized. Turbidity barriers will be installed before any in-water work and maintained until interior water quality is within acceptable levels. Double turbidity bathers will be required if pile socketing is required. 5.00g Maintenance of Sediment and Siltation Control Measures All silt fencing and turbidity bathers will be inspected and maintained through the construction period. Silt fencing will be inspected daily even when no construction is in progress (over weekends/holidays). Turbidity bathers will be monitored throughout the II EFTA00802735 day and will be repaired and adjusted as necessary as part of the water quality monitoring plan. Curtains will be maintained throughout the day and removed or secured as necessary when no in-water work is ongoing. 5.02 EXHIBITS AND DRAWINGS Drawing Page Proposed Temporary Barge Landing 11 Western Access 12 Southern Access Dock/Barge Access 13 As-built Drawings for Existing Dock 14 As-built Drawings for Existing Dock 15 12 EFTA00802736 AMC SCA Ira 07.1121a alba ill011/60 'MO 'Da OF VIC/ l•••••0•••• e▪ st Swim SI•••••••• •••••••••• ali.••••••• •••••••••••••• ••••••••••••••• li•••• Swag.

These trade winds vary seasonally (Figure 6.01.1) and are broadly divided into 4 seasonal modes: I) December to February; 2) March to May; 3) June to August; and 4) September to November. Below are the characteristics of these modes as taken from Marine Environments of the Virgin Islands Technical Supplement No. I (IRF, 1977). December - February During the winter the trade winds reach a maximum and blow with great regularity from the east-northeast. Wind speeds range from eleven to twenty-one knots about sixty percent of the time in January. This is a period when the Bermuda High is intensified with only nominal compensation pressure changes in the Equatorial Trough. The trade winds during this period are interrupted by "Northerners" or "Christmas Winds" which blow more than twenty knots from a northerly direction in gusts from one to three days. Such outbreaks average about thirty each year. They are created by strengthening of high-pressure cells over the North American continent, which, in turn, allow weak cold fronts to move southeastward over the entire Caribbean region. Intermittent rains, clouds and low visibility accompany these storms. March - May During the spring, the trade winds are reduced in speed and blow mainly from the east. Winds exceed twenty knots only thirteen percent of the time in April. The change in speed and direction is the result of a decrease of the Equatorial Trough. June - August Trade winds reach a secondary maximum during this period and blow predominantly from the east to east-southeast. Speeds exceed twenty knots twenty-three percent of the time during July. The trend for increasing winds results from the strengthening of the Bermuda High and a concurrent lowering of the pressure in the Equatorial Trough. Trade winds during this period are interrupted by occasional hurricanes. September - November During the fall, winds blow mainly from the east or southeast and speeds reach an annual minimum. Only seven percent of the winds exceed twenty knots in October. The low wind speeds result from a decrease in the Equatorial Trough. During this period, 19 EFTA00802743 especially during late August through mid-October, the normal trade wind regime is often broken down by easterly waves, tropical storms, and hurricanes. Storm and Hurricanes There are numerous disturbances during the year, especially squalls and thunderstorms. These occur most frequently during the summer, lasting only a few hours, and causing no pronounced change in the trade winds. A tropical cyclone whose winds exceed 74 miles per hour is termed a hurricane in the northern hemisphere, and significantly affects the area. These hurricanes occur most frequently between August and mid-October (Figure 5) with their peak activity occurring in September. The annual probability of a cyclone is one in sixteen years (Bowden, 1974). Climate No rainfall data is available for Great St. James. However, based on the vegetation on the island the island which is dry adapted, it is probable that the island gets between 36-45 inches of rainfall a year. Rainfall usually occurs in brief, intense showers of less than a few tenths of an inch and major rainfall events are associated with weather systems (USGS 1998). The Virgin Islands have no sharply defined wet season. The wettest period generally is from September to November, and the driest period is from January to June (USGS 1998). The Cruz Bay which is the closest monitored station receives between 39 inches of rainfall annually. The average rainfall received between 1972 and 2012 is found in the table below.

Tropical Storm and Hurricane Occurrences in the Atlantic (National Weather Service) 6.02 Landforms, Geology, Soils, and Historic Use GEOLOGY OF ST. THOMAS, ST JOHN AND SURROUNDING CAYS The Virgin Islands are near the northeastern corner of the present Caribbean Plate, a relatively small trapezoidal-shaped plate that is moving eastward relative to the North and South American continents carried on the American plate. The arc of the Lesser Antilles is an active volcanic arc above a subduction zone in which the Atlantic oceanic crust of the American Plate is carried downward under the Caribbean Plate. The closest volcano to the Virgin Islands that is still active is Saba, about 160 km. to the east. St. John is 7 miles long and 3 miles wide for a total of 12,000 acres or 19 square miles. The oldest rocks of St. John are submarine lavas (keratophyre and spilite), beds of volcanic debris and chert. Associated intrusive rocks of the Water Island Formation is overlain by andesitic volcanic and volcanoclastic rocks of the Louisenhoj Formation which underlies the island of St. Thomas to the east and much of the northwestern portion of St. John. Donnelly (1966) suggested that the Louisenhoj Formation was deposited unconformably on the Water Island Formation after a period of emergence, tilting and erosion, on the slopes and environs of a subaerial volcanic island located roughly between St. Thomas and St. John, an area now occupied by Pillsbury Sound. The youngest layered deposits on St. Thomas are volcaniclastic rocks of the Tutu Formation. Fossils contained in the Tutu Formation suggest that those deposits are of the Early Cretaceous (Albain) Age (Donnelly et. al. 1971). It appears that all of the volcaniclastic rocks of St. Thomas and St. John were deposited in a relatively short period of time spanning 10 to 15 million years approximately 100 million years ago (D. Rankin 1988). 23 EFTA00802747 GEOLOGY OF GREAT ST. JAMES The island which lies off the eastern tip of St. Thomas is irregularly shaped, and has two fault lines running across the island. The island is comprised of 162 acres and rises to an elevation of 186 feet above sea level. The island is a part of the Water Island Formation that was lain down in the Lower Cretaceous. The northern tip is tonalite, gabbro and granite from the tertiary period, the north-western tip as well as the southeastern tip of the island is basalt, and the southwestern tip is undivided, mostly keratophyra. The central portion of the island and the northeastern point is part of the Louisenhoj Formation. The shorelines are a combination of sandy beach, cobble beach and shear rocky cliffs. There are 6 salt ponds on the island. SOILS OF THE PROJECT SITE The Custom Soil Survey of the Unites State Virgin Islands has classified 6 soil types on the islands of Great St. James. Cinnamon Bay gravelly loam (CgC), 5 to 12 percent slopes, occasionally flooded is usually found on alluvial fans and terraces adjacent to volcanic uplands. It has a surface layer which is 0 to 5 inches deep that is a very dark grayish brown gravelly loam, the subsurface is 5 to 10 inches deep and is a dark brown gravelly loam. Redhook extremely stony sand (RdB), 0 to 5 percent slopes, rubbly, rarely flooded is usually found on coast beaches that are composed of calcareous sand. It has a surface layer 0 to 7 inches deep of dark brown extremely stony sand, underlain with 7 to 10 inches of brown very stony and 10 to 16 inches of very pale brown very gravelly sand below which is 16 to 60 inches of white very gravelly sand. Salt flats ponded (SaA) consist of area of unvegetated saline flats, saline marshes and salt ponds. The soils are very deep and poorly drained, strongly saline and frequently ponded for very long periods. Southgate-Rock outcrop complex (SrE), 20 to 40 percent slopes is found on the summits and side slopes of volcanic hills and mountains. It has a surface layer of 0 to 5 inches of brown gravelly loam and a subsoil of 5 to 10 inches of brown very gravelly loam underlain by 10 to 17 inches of weathered igneous bedrock and 17 to 60 inches of unweathered igneous bedrock. Southgate-Rock outcrop complex (SrF), 40 to 60 percent slopes is found on the summits and side slopes of volcanic hills and mountains. It has a surface layer of 0 to 5 inches of brown gravelly loam and a subsoil of 5 to 10 inches of brown very gravelly loam underlain by 10 to 17 inches of weathered igneous bedrock and 17 to 60 inches of unweathered igneous bedrock. Solitude gravelly fine sandy loan (SoA), is found in areas that are adjacent to saline marshes, flats and salt ponds and are a mixture of terrestrial and marine sediments. 24 EFTA00802748 MOM I I I I I I I I g QS Iliecume Rag Sal lap WOOS 1 02000•••••••••••Ore @MOM • • • •m A n — ess i • I—. —a . ° 'twig.= noses owes .•• mos wanes•oloi Figure 6.02.1 Custom Soils map of the project area (USGS Custom Soil Survey (https://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspx) HISTORIC USE I I I I I I I I The archeological survey found no evidence of prehistoric habitation. There are no structures shown on the island before 1760 on any of the historic maps. The island is reported to have been under cultivation since the 1760. Around 1770, a cotton plantation was established and cotton was cultivated until approximately 1815. Great St. James was continuous occupied between 1760 and 1911. Today there is a house and complex located off the northern bay which is often referred to as Shallow Bay ADVERSE SITE CONDITIONS The island is protected by its location between St. Thomas and St. John and the surrounding cays. The northern temporary barge landing is protected by the other cays to the north, and St. Thomas and St. John to the west and east. Waves do attenuate in Pillsbury Sound and the area can be affected by large seas and swells. However, there are no offshore structures other than the buoys and barges using the site should be moored no more than a couple of hours. Under normal sea conditions the Christmas Cove Dock and the Southeastern Dock/Barge Landing are well protected by their locations in relation to the prevailing seas which are 25 EFTA00802749 usually from the east, southeast or northeast. During storms and during some periods of the winter, seas can approach from the southwest. The Christmas Cove dock could be effected by waves approaching between 220° to 250° and the Southwest dock would be effected by waves coming from 210' to 240'. Waves occur from this direction primarily during storm events. When seas become extremely rough or storms approach vessels would be taken to more protected anchorages. All three sites lie with area VE elevation 8ft where FEMA has determined that the 100- year flood elevation with velocity will be 8ft as shown on FIRM maps 45 and 30 below. Figure 6.02.2. FEMA FIRM Map Panel 45 of 94. 26 EFTA00802750 Figure 6.02.3 FEMA FIRM Map Panel 30 of 94. The U.S. Virgin Islands lie in one of the most earthquake prone areas of the world, and are susceptible to ground shaking, earthquake-induced ground failures, surface fault ruptures and tsunamis (tidal waves) (Hays, 1984). The activity is mostly associated with large-scale tectonic activity or faulting, originating in the Anegada Trough to the northeast of the islands. The trough and its related scarp apparently were thrown up by block faulting during the late Pliocene or early Pleistocene. It is oriented generally northeast to southwest, separating St. Croix from Puerto Rico and the other Virgin Islands. Based on shallow focus earthquakes, the Anegada Fault Trough is estimated to be more than 400 miles in length. There are indications that strike slip movement is occurring, with St. Croix shifting northeast relative to Puerto Rico (Puerto Rico Water Authority 1970). The year 2018 marks the 151th anniversary of the last major earthquake in the islands. This quake, which occurred on November 18, 1867 had an identified intensity of VIII on the Modified Mercalli Scale. Earthquakes of this magnitude have generally been associated with epicentral ground accelerations of between 0.05 and 0.35 gravities. Since the 1868 quake, there has been continuous low intensity activity, all below 6.0 Richter. Thousands of tiny earthquakes are encountered every year on the island. 27 EFTA00802751 IMPACT OF SITE GEOLOGY ON THE DOCK The site geology will have little impact on the construction and placement of the temporary barge landing. Both other docks will be impacted by the site geology which will dictate how the pilings can be installed. It is probable that the pile in the pavement areas will have to be socketed. Once beyond the pavement a vibratory hammer can be utilized. IMPACT OF THE PROJECT ON GEOLOGICAL RESOURCES No dredging or filling is proposed, therefore there will be negligible impact on the geology of the area. The emergency ramp will be removed as soon as the proposed barge landing is constructed and the shoreline will be restored to pre-ramp conditions. 6.03 Drainage, Flooding, and Erosion Control 6.03a Impacts of Terrestrial and Shoreline Erosion The project includes the construction of 3 landing or access pads on cobble beaches between rocky headlands. These pads are all limited in size the largest being just over 1000sqft. Due to the small size of these introduced impervious surfaces none should result in any notable change in terrestrial runoff. Both docks are pile supported and in areas of rocky or cobble beaches. Neither dock site has sand deposition on the beach and the cobbles found on both beachesare moved by wave action rather than littoral transport. The construction of the docks should not result in any shoreline erosion. 6.03b Relationship of the Project to the Coastal Flood Plain All three sites lie with area VE elevation 8ft. where FEMA has determined that the 100- year flood elevation with velocity will be 8ft as shown on FIRM maps 45 and 30 provided in Section 6.02. 6.03c Presence and Location of any Critical Areas and Possible Trouble Spots The island of Great St. James is within the Vessup Bay/ East End Red Hook Area of Particular Concern (APC) (Figure 5.01.1). The Vessup Bay/Red Hook APC is located on the eastern end of St. Thomas and includes Nazareth, Muller, Vessup, Red Hook, Great Bay, Cowpet Bay, Cabrita, Beck and Water Point, Great St. James, Little St, J, and Dog Island. 28 EFTA00802752 Figure 5.01.1 Areas of Particular Conem (STEER (2011) St. Thomas East End Reserve Management Plan.

St. Thomas, USVI. 30 EFTA00802754 The regulations for the St. James are as follows: St. lames Marine Reserve and Wildlife Sanctuary Subchapter 96, Section 96-3 Prohibited Activities within the St. James MRWS: • It is unlawful to remove any marine or other wildlife without a permit or specific authorization from the Commissioner Subchapter Permitted Activities within the St. James MRWS: 96, Section 964 Acts permitted, provided a permit is first obtained from the Commissioner: • Scientific collecting in support of and for use in a research project with an approved protocol • The use of castnet with a minimum square mesh size of X inch to capture baldish (fry) within 50 feet of the shoreline, except for Cow and Calf rocks • Fishing with hook and line The marine habitats around Great St. James have abundant coral and seagrass resources. There are numerous ESA listed corals species near the proposed dock locations. Acropora palmata, Acropora. cervicornis, Orbicella amzularis, Orbicella franksi and Orbicella faveolata as well as Dendrogyra cylinders are found off all the beach from which the proposed docks and barge landings are planned. At the northern temporary barge landing site, these corals are located primarily to the west in an area of coral boulders and coral rubble. However, there are several small A. palmata and several 0. amiularis located on the shoreline cobble which extends out to a depth of 6.5ft. The presence of these species as well as several non-ESA listed Porites astreoides has dictated the location of the ramp. The proposed temporary barge landing position avoids all coral and seagrass resources. Location of the western dock has a cobble beach between two areas of emergent bedrock and boulders. A. palmata occur on the emergent bedrock to the north. Offshore the seafloor quickly gives way to exposed pavement. There is a long linear depression right offshore and an old piling lies within this area. The fractured pavement then extends to approximately 11.5ft of depth over the next 100ft heading offshore. The area has some widely-scattered boulders and patchy coral colonization. There are scattered ESA corals including Orbicella and Dendrogyra. During the first survey, there was a very large A. pabnata colony immediately seaward of where the old piling lay near shore. However, upon the next visit by the island it was noted that an old boat was tied nearshore apparently attached to the old piling. During a dive, several weeks later it was noted that the boat was gone and the large A. cervicornis had been badly broken. The location of all the ESA species has dictated the location of the dock. Approximately 75 corals will require relocation to minimize impact, but no listed corals will need relocation. 31 EFTA00802755 The southern dock also extends from a cobble beach which gives way to rock pavement and has emergent bedrock and boulders on either side of the beach. There are Acropora colonies to the east and farther to the south on the bedrock and boulders. There are Orbicella and Dendrogyra within the embayment and their locations have dictated the location of the dock. The dock avoids all ESA listed corals but will require the relocation of approximately 75 corals. This southern dock will include a combination wave attenuator and reef building system. A mitigation plan has been prepared and is found in Appendix B. Because of the rock occurring in the area, some of the pilings may require socketing and if this is required special water quality measures will be taken. If at all possible a vibra- hammer will be used to drive the piles. A water quality monitoring program has been proposed and the plan is found in Appendix C. The area is known habitat to protect sea turtles and marine mammals and as such NOAA's Sea Turtle and Smalltooth Sawfish Construction Conditions will be followed as well as NOAA's Vessel Strike Avoidance Measures and Reporting for Mariners. The property contains 6 salt ponds. The wetland around the salt ponds have been delineated and the delineations were approved by the U.S. ACOE during a previous application for development of the island. This delineation is more than 5 years old, but no wetland disturbance will occur as a result of this project. The island is known to be habitat to the St. Thomas Tree Boa that is a listed rare and endangered species. The boa as well as another species of snake have been seen during the field studies. There will be special corridors and preservation areas set aside on the island for these species. The access ways to the western and southern docks already exist, but the branch that will need to be developed to the temporary barge landing will be cleared by hand to limit impacts to the tree boas. A tree boa mitigation plan is found in Appendix D. Both emergency barge ramps consisted of cobble pushed out from the shoreline and boulders being placed around them to stabilize. Both extended approximately loft. beyond the MHW line and both were approximately 15ft. wide. Both extended out over uncolonized coral rubble so no corals were directly impacted. Neither barge landing appeared to be creating turbidity impacts when they were surveyed. The southern ramp has been removed and the applicant would like to keep the emergency ramp in Christmas Cove until the proposed ramp is constructed. 6.04 Fresh Water Resources There are no freshwater resources on the island of Great St. James. There is no potable water use planned for either dock or the temporary barge landing. 32 EFTA00802756 6.05 Oceanography 6.05a Sea Bed Alteration Great St. Jim, LLC is seeking to construct two docks, one of which is a combination dock/barge landing and a temporary barge landing to provide access to Great St. James Island. A detailed study was conducted around the entire island to determine suitable locations for the dock locations and sites with the least environmental impact were chosen. A temporary barge landing is being proposed on the northwestern facing embayment. The barge landing can be quickly constructed and utilized while the combination dock/barge landing on the southeastern side of the island is constructed. This site is to the west of the sand pond and its associated wetlands. The landing includes a shoreline ramp which is 25ft wide and 40ft in length extends to the Mean Water Line (MWL). Two bollards will be placed to either side of the ramp and two moorings will be installed 75ft offshore on either side of the ramp in just over 7ft of water depth. This will allow barges to moor rather than to use their props to stay in place and will minimize bottom disturbance. The moorings will be installed using helix anchors and will use floating lines as to not disturb the seafloor when not in use. The landing area is free of coral colonization and just offshore there is very sparse seagrass colonization. The western dock is proposed on the northern end of Christmas Cove. Historically there was a dock in this location and there are still old concrete piles lying in the shallows of this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft from MLW and 193ft from mean high water (MHW). The dock will connect to an access slab which is 12ft xl2ft and the slab will be 2ft thick. All the ESA listed coral species within the area were located with GPS and the dock footprint avoids the ESA listed species. The dock extends beyond the nearshore hardbottom out to a depth of 15ft into an area of uncolonized sand to allow for safe dockage for deeper vessels and minimum impact by vessels to the seafloor. The dock will require sixty-six 12in diameter piles. The southern dock is located off the point closest to Little St. James. The ESA corals were located by GPS and survey and the dock was designed to avoid these coral species. The dock is "L" shaped and is 20ft wide (to allow for barge landing) and 150ft in length extending 141' from MLW and 148' from MHW, the "L" turns east and is 20ft wide and 100ft in length. A combination wave attenuating/reef creating system is proposed beneath the dock which will allow for more protected docking inside the "L" when seas from the south are rough. The dock has 9ft of water depth off the southern end and 7ft to 8ft on the inside of the "L". The dock has been designed so that barges can approach and land on the south end of the dock while vessels can dock along the "L". There will be 152 12in diameter dock piles and forty-three 12in diameter wave attenuator piles. The attenuator/reef building piles provide substrate designed additional surface to allow colonization by coral and sponge species. 33 EFTA00802757 After the hurricane Irma in 2017 the owner of the Great St. James assisted many of his employees and their families who had lost their homes and housed people on the island. In order to bring in emergency supplies, two small barge ramps were created near the locations of both proposed docks; one in Christmas Cove and one off the closest point to Little St. James. Both emergency barge ramps consisted of cobble pushed out from the shoreline and boulders being placed around them to stabilize. Both extended approximately 10ft. beyond the MHW line and both were approximately 15ft. wide. Both extended out over uncolonized coral rubble so no corals were directly impacted. Neither barge landing appeared to be creating turbidity impacts when they were surveyed. The southern ramp has been removed. 6.05B TIDES AND CURRENTS The Virgin Islands coastal areas are not subject to significant tidal ranges or tidal currents. Due to the small size of the island, the sea flows around the island causing an average tidal height of only a few inches and maximum change of only a little over a foot. Only very narrow intertidal zones are found because of this lack of tidal amplitude and the steepness of the island rising out of the sea. The tides around Great St. James are primarily semi-diurnal in nature, with two cycles of high and two of low water every 24 hours. The second cycle is often indistinguishable. The mean tides range from 0.8f. to 1.0 ft and the spring tidal ranges reach up to 1.3ft (IRF 1977). There are no notable locally driven tidal currents due to the lack of confinement within the area. NOAA has a tide gauge in Charlotte Amalie which is a southern exposure which has been recording water levels since 1975. The high tide recorded on September 18, 1989 (Hurricane Hugo) was +3.35ft, and in 1995 during Hurricane Marilyn the Charlotte Amalie tide station recorded the highest tide height 3.98ft above Mean Lower Low Water (MLLW). The lowest tide recorded was on February 6, 1985 and was -1.44ft. The tidal ranges of the Charlotte Amalie station are as follows: Mean Higher High Water 1.09ft Mean High Water 0.94ft Mean Tide Level 0.54ft Mean Sea Level 0.52ft Mean Low Water 0.13ft Mean Lower Low Water 0.0ft There is also a Tide Station in Lameshure Bay, St. John (Station ID: 9751381), the station is located at latitude 18° 19.0' N and longitude 64° 43.4' W and has a mean tidal range of 0.72 ft and a diurnal range of 0.82 ft. 34 EFTA00802758 NOAA/NOS/CO-CPS Predicted Water Level Plot 9751381 Lameshur Bay, St. John, VI from 2011/04/13 - 2011/04/14 0.800 • 0 700 • 0.600 ▪ 0.500 ,r, ^ 0400 L 0..300 1 0.100 L.1.- 0.000 a 04/13 .c 00 00 04/13 04/13 04/14 04/14 04/14 04/15 08:00 16:00 00:00 08:00 16:00 00 00 Date/Time (GMT) Predicted WL Figure 6.05.1. Tidal data from the Lameshure Tidal Station (NOAA Buoys) The surface currents throughout the Caribbean are driven by the North Equatorial Current that runs through the islands west-northwest and then joins the Gulf. These currents change very little from season to season with the currents coming more from the south during the summer months. Because of the shallowness of the Caribbean basin of less than 1000m, mainly surface water from the Atlantic flows through the islands. The westerly drift of the Caribbean Current sweeps into Pillsbury Sound from the Southeast, seeking a way North through the barrier set up by the Cays to discharge along the North Shore of St. Thomas and out into the Atlantic. The current flows past Great St. James in a northwesterly direction. Due to the formation of the island and the normal water movement into Pillsbury Sound from the south, there is frequently a strong southerly current running between Great St. James and Little St. James and through Current Cut. 6.05C WAVES The deep-water waves off Great St. James are primarily driven by the northeast trade winds that blow most of the year (Figure 6.05.1). Waves average from 1 to 3ft from the east, 42% of the time throughout the year (IRF, 1977). For 0.6% of the time easterly waves reach 12ft in height. The southeasterly swell with waves one to twelve feet high become significant in late summer and fall when the trade winds blow from the east or when tropical storms and hurricanes pass the islands at a distance to the south. During the winter months, long length, long period northern swells develop to a height of 1 to 5 feet. The USACE Hindcast Studies for buoys 61022 and 61025, the two buoys whose waves patterns directly affect the island, show that a majority of the waves which occurred approach from easterly directions. 6.05D MARINE WATER QUALITY The dock locations all have excellent water quality. During baseline studies for the dock construction on Little St. James, baseline samples taken between Little St. James and Great St. James found turbidities to range from 0.27 NTU to 1.17 NTU under normal sea conditions. Samples taken those previous studies are shown below. 35 EFTA00802759 DATE TURBIDITY TURBIDITY TURBIDITY TURBIDITY NORTH EAST SOUTH WEST 10/06/03 0.67 0.56 0.73 0.54 10/17/03 0.44 0.74 0.67 0.37 10/24/03 0.65 0.71 0.87 0.47 2/6/04 0.54 0.36 0.74 0.85 2/14/04 0.64 0.86 0.78 0.34 2/17/04 0.85 0.76 0.56 0.65 12/28/04 0.45 0.78 0.67 0.54 1/12/05 0.76 0.87 0.34 0.56 2/15/05 0.56 0.67 0.58 0.75 4/30/05 0.32 0.45 0.71 0.60 10/12/05 0.56 0.72 0.39 0.61 10/15/05 0.63 0.58 0.79 0.83 Turbidly measurements (NTU) during studies for this project as as follows Date/Location Temporary Barge Landing West Dock Southeast Dock 3/20/2016 0.91 0.88 0.75 4/15/2016 0.57 0.71 0.71 6/1/2016 0.49 0.91 0.87 6/27/2016 0.80 0.54 0.66 7/11/2016 0.76 0.76 0.61 8/2/2016 0.93 0.79 0.87 8/23/2016 0.62 0.82 0.68 9/3/2016 0.63 0.75 0.74 The offshore waters are classified as Class B and the best usage of the water is listed as the propagation of desirable species of marine life and for primary contact recreation (swimming, water skiing, etc.). The quality criteria include, dissolved oxygen not less than 5.5mg/1 from other than natural conditions. The pH must not vary by more than 0.1 pH unit from ambient; at no time, shall the pH be less than 7.0 or greater than 8.3. Bacteria (fecal coliform) cannot exceed 70 per ml, and turbidity should not exceed a maximum nephelometric turbidity unit of three (3) NTU. IMPACT OF PROPOSED PROJECT The temporary barge landing and docks will replace the use of the landing and dock in Shallow Bay. Both frequently result in the suspension of sediment from the seafloor. The upland construction associated with the docks and landing are minor and with proper 36 EFTA00802760 siltation control should not result in any impact to marine water quality. The placement of pilings will probably require socketing and could impact water quality. A double set of seafloor length turbidity bathers will be required, and all corals will be relocated out the bather footprints. Bathers must be maintained until such time the interior water quality is acceptable. If properly implemented and monitored the socketing should have only a very short-term limited impact on water quality. A Water Quality Monitoring Plan is proposed and is found in Appendix C. Once constructed, the docks and landing will have negligible impact on water quality. The docking areas are all deep enough that there should not be an issue with propwash. The emergency barge ramp in Christmas Cove will be removed from the shore by backhoe as soon as the proposed barge landing is operational. The cobble will be pulled back onto the beach and spread across the back beach. The boulders will be taken inland to use in landscaping. Minor turbidity may occur during the removal of the ramp. Turbidity barriers will be placed round the ramp prior to removal. The water is shallow enough that no corals should be impacted. The use the docks by vessels will increase the potential for releases of hydrocarbons into the marine environment through spills and exhaust. No fueling or maintenance will be allowed on the docks. To mitigate potential spills, fuel spill supplies will be kept near the base of the docks so that they can be deployed in the event a release occurs. No pumping of bilges or live-a-boards will be allowed on the dock. • •• r 9' r 1\5 "".." • - • "-•. c-ThN '-. -V- . • `1. -2/•• j<- • V. •1:- • ‘6( -v- NA. .‘4‘ - ‘I•CCI\k \e. 0 \: t4Q -V. -41•• . 4" *4.• 4 3- •-ae-...t • 5. -V tc:4 e ANNUAL PREVAILING CURRENTS . . .

All three of the proposed dock and barge landing sites will extend from cobble beaches. The northern shore where the temporary barge landing is proposed has cobble which extends down to a depth of approximately 7ft and has sparse seagrass colonization within the barge approach. There are scattered corals in the bay to the east and dense seagrasses offshore beyond the landing site. The cobble within the landing site is only colonized by fire coral. The emergent bed rock to both the east and west sides of the bay are colonized by corals species including ESA corals. The northern portion of Christmas Cove where the Access Dock is located has emergent bedrock to either side of the small embayment which are colonized by coral and sponge species. Rock pavement and scattered boulders extends offshore to a depth of I I.5ft where it gives way to a sandy bottom. Corals and sponges colonize the rock pavement and scattered boulders. There is seagrass off shore, but it begins beyond the terminus of the proposed dock. The southern facing dock is off a cobble beach between to rocky shorelines. There is rock pavement extending off shore and then broken rock pavement further out. Corals and sponges colonized the rock pavement. ESA listed coral species are found at all three locations and the Nassau Grouper (Epinephelus striatus) was seen off both the Christmas Cove and southern dock site. After the hurricane Irma in 2017 the owner of the Great St. James assisted many of his employees and their families who had lost their homes and housed people on the island. In order to bring in emergency supplies, two small barge ramps were created near the 40 EFTA00802764 locations of both proposed docks; one in Christmas Cove and one off the closest point to Little St. James. Both emergency barge ramps consisted of cobble pushed out from the shoreline and boulders being placed around them to stabilize. Both extended approximately 10ft. beyond the MHW line and both were approximately 15ft. wide. Both extended out over uncolonized coral rubble so no corals were directly impacted. Neither barge landing appeared to be creating turbidity impacts when they were surveyed. The southern ramp has been removed. Methods The NOS St. John and St. Thomas Habitat Map Tile 16 (Figure 6.06.1) of the Great St. James area shows the colonized rock pavement and bedrock as well as the offshore seagrass beds. The seagrass beds are not as continuous near the shoreline as shown, and the offshore area at both Christmas Cove and the southern dock site are colonized pavement rather than bedrock right off the cobble beaches and on the northern facing beach the pavement doesn't extend completely across the bay as shown. Surveys were done on Scuba and Acropora palmata and Acropora cerviconds, Dendrogyra cylindrus, Orbicella annularis, Orbicella faveolata, Orbicella franksi, and Mycetophyllia ferox were mapped so that they could be avoided. Habitat boundaries were marked with GPS and/or by the surveyor for accuracy. Percent abundance was determined along transect lines and utilizing a meter square. as ...

This oddly shaped island has a variety of shoreline types and six salt pond/wetland habitats. There is a well-protected shallow northern bay where an existing dock is located. Shallow Bay is colonized by seagrass which includes Thalassia testudinum, Syringodium filzfonne and Halodule wrightii. Recently the sea vine Halophila stipulacea has colonized areas which have been disturbed. The densest seagrass beds once lay near shore and to the east of the dock. Over the last several years these beds have been highly disturbed. The peninsula to the east of this point is surrounded by rocky headlands and is a very exposed environment. The rocky cliffs extend below the sea surface and due to the intense wave action, the shallowest areas are not colonized. By a depth of 8ft-10ft the rocky substrate becomes colonized by a wide variety of corals and sponges. The slope is steep offshore and the water reaches a depth of 40ft to 50ft relatively close to shore. The rocky slope gives way to a cobble then sand bottom and there are sparse to moderately dense seagrass beds that extend seaward. The rocky shoreline continues around to the south, with coral colonized nearshore hardbottom and seagrass colonized sand and cobble further offshore. There are two cobble beaches further to the south divided by a small rocky headland, there is some colonized beach rock nearshore and shallow seagrass beds off shore. The shoreline facing St. James Cut and the southern end of the island is rocky. This area has limited coral colonization in the inner tidal zone giving way to an abundant diverse coral community on the submerged rocky slopes. The rock is relatively steep with numerous grottos, and caves, and gives way to a cobble/sand bottom at around 20ft to 25ft. There are moderate to dense seagrass beds off shore. The Stragglers lay off the southern most point of the cay, and like the southern shoreline of the island there is minimal colonization in the inner tidal areas of the emergent rocks with coral colonization and diversity increasing with depth. The western shoreline is well protected and is a combination of rock and sandy beach. The water deepens much more gradually on this side of the island. In the areas with rock along the shoreline are colonized by corals and sponges. The less colonized inner tidal area is much less defined here due to the more protected nature of the site. Within Christmas Cove there is a rock groin like structure that extends into the bay near the center of the embayment. Offshore to the north of the groin there is a small beach rock shelf and then a strip of uncolonized sand before sparse to moderately dense seagrass beds begin. The site is currently used by boats anchoring adjacent to the beach. To the south of the groin there is a beach rock shelf with moderate coral colonization which falls off to depth of over 6ft only 40ft from shore and there is a board area of uncolonized sand out to a depth of 10ft before reaching the moderately dense seagrass beds and open sandy plains. The shoreline becomes rocky again to the north along Current Cut and the area is more subject to wave and current action. There is coral colonization along the rocky shoreline and on the rock pavement that extends off shore. The north-facing bay to the east of Current Cut is a mixture of cobble and rocky shoreline with a small sandy beach in front of the salt pond. Where rock is present there is coral colonization and in the open sandy areas there is moderate to dense seagrass colonization. 42 EFTA00802766 - The temporary barge landing is located at the western end of the north-west bay. The landing. The beach is cobble and the cobbles extend out to a depth of 7ft at the landing site. The landing site contains some scattered Millepora complanata, but no hard-coral species. There are scattered corals to the east in the cobble including a few Orbicella annularis and Acropora pahnata. Porites astreoides is the most abundant coral in the cobble to the east. The location for the barge ramp was chosen due to the presence of corals and coral colonized boulders throughout the bay to the east. To the east in the bay there are numerous Orbicella annularis, O. faveolata and Dendrogyra cylindrus as well as other coral species. Offshore there are dense seagrass beds consisting of 77u2lassia testudinum and Syringodium fihforme, however these are greater than the 75ft off shore which the barge will extend while moored. There very sparse Syringodium colonization within the barge approach, representing less than 5% bottom coverage.

The beach is a mixture of sand and cobble. There is rock pavement extending offshore and there is an area of cobbles in the center of this area which is uncolonized out to a depth of 5ft. The rock pavement has various depressions and breaks and within one of these depression is a pile from the old concrete dock. Beyond the depression, the water deepens quickly out to a depth of 12ft. The rock pavement is colonized by Diplona strigosa, D. labyrinthifonnis, Orbicella annularis, 0. franksi, Porites astreoides, P. porites, Dendrogyra cylindrus, Gorgonia sp. and Millepora sp. and the sponges Aplysinafidva, Amphimedon compressa and Ircinia sp. Coral colonization increases on either end of the small embayment and with depth. Beyond the nearshore hard bottom, approximately 120ft off shore the bottom becomes sandy. There is a minimally colonized area before the bottom begins to become colonized by Syringodiumfilifonne which slowly grades into a mixed bed of Thalassia testitudium and Syringodium. The exotic seavine Halophila stipulacea is also present. This seavine was not present in 2006. There was a very large intact Acropora cerviconzis in the center of the bay just off the old dock piling in the depression early in 2016. However, a boat moored on the old piling and on a subsequent dive the Acropora was found completely broken. Pieces of this Acropora remain. There are Acropora palmata in the shallows to the north of the proposed dock location both on the cobble and bedrock. 44 EFTA00802768 The bottom formation is dead visible this •hoto• a h.

Like the other two bays there is cobble on the shoreline which extends into the sea to 2ft to 4ft of water depth. Offshore there is pavement with boulders and odd rock formation. The area is colonized by scattered corals which are most abundant on the boulders. Orbicella annulans, O. franksi, O. faveolata, Dendrogyra cylindrus, Porites astreoides, P. porites, Diplona strigosa, D. clivosa. D labyrinthifonnis Gorgonia sp. and Millepora sp. and sponges Aplysinafidva, Amphinzedon compressa and Ircinia sp. are present. Acropora palrnata is present on the headlands to the east and south.

The landing pad is landward of MHW and only two moorings will be placed offshore. Moorings will be placed with helix anchors and will utilize floating lines to minimize impact to the seafloor. There is very sparse Syringodiwn coverage in the immediate approach and the installation of the anchors should have a negligible impact. The barge will come into the landing tie up to the bollards and pick up the moorings and cut off its engines to minimize impact. The end of the barge will be in 7ft of water at the edge of the cobble where the sand is uncolonized. By not using is engines to maintain position on shore the impact to the seafloor and water quality should be minimal. The barge will not be in place long enough to have a shading impact on the seafloor. There are approximately 75 corals in the footprint of the Christmas Cove Dock and its immediate impact area. The corals will be relocated to the hardbottom areas to the north prior to any construction. A Coral Relocation and Transplant Plan is found in Appendix B. The Christmas Cove dock will require sixty-six I2in pilings. It is probable that a least 1/2 of those will require socketing. Double turbidity barriers will be deployed, and water quality monitored will be conducted during all in water work. Turbidity barriers will not be opened or removed until interior water quality has settled to acceptable levels. All corals will be relocated out of the area enclosed by the curtains so that they will not be impacted by settling sediment. Turbidity barriers will be removed or secured when not in use to limit impact to the surrounding benthos. If turbidity control is properly maintained and monitored the impacts should be minimal. The dock has been designed to extend out into the uncolonized sand and terminate before reaching the dense Thalassia and Syringodiwn beds offshore. The seavine Halophila stipulacea may now be in the footprint of the dock. During the initial surveys, it was well beyond the dock footprint but has slowly been spreading into the uncolonized sand. The use of the dock will introduce the potential for hydrocarbon releases from motorized vessels and from their exhaust. This bay is already highly used by sail and motor vessels and the increased potential for releases should not be significantly over what is currently present. The southeastern dock/barge ramp will also impact approximately 75 corals in its footprint and impact area. These corals will be transplanted onto the hard bottom areas to the south. The dock will require one hundred and sixty-six 12" piles and forty three 12" piles for the wave attenuators and reef building system. Many of the piles may require socketing and the same procedures will be followed as described for the Christmas Cove installation. If properly implemented impacts to water quality should be minimal. The depths are such that the dock's use should not disturb the seafloor. The use of the dock will introduce the potential for hydrocarbon spills from vessels and from the exhaust. The locations of the docks have been made so that they avoid impact to ESA listed coral species and provide the greatest depth possible while minimizing the size of the structures. 48 EFTA00802772 The Emergency Barge Ramps The ramps were constructed shortly after the passage of hurricane Irma on September 6, 2017. They were constructed of coral rubble and cobble from the beaches and boulder riprap was used to stabilize the sides. I Christmas Cove ramp. the ramp has slowly been deteriorating. The southern emergency ramp has been removed and the shoreline restored. 49 EFTA00802773 Fortunately, neither ramp extend far enough offshore to impact coral resources and both were on cobble. Neither ramp was noted as creating turbidity during several surveys. The Christmas Cove ramp has somewhat deteriorated since it was constructed and the cobbles are spreading into the surround cobble. 6.07 Terrestrial Resources The application is for the development of a temporary barge landing and two docks. All three structures have access pads or landing pads which will be constructed on cobble beaches which are unvegetated. The access ways to both the Christmas Cove beach and southeastern dock already exist and will not require additional clearing. Approximately 175' of access way must be cleared in order to access the temporary barge landing. Flora The island is a harsh dry windswept environment that supports a large variety of thorny species. There are 6 wetlands, two of the wetlands are salt ponds surrounded by monocultures of black mangroves (Avicenna genninans) and two of the wetlands are salt ponds surrounded by buttonwood mangroves (Conocarpus erectus). One of the wetlands is more depressional and is surrounded by manchineel (Hippomane manchineel). A plant species list follows which provides the general location for each of the species encountered during detailed terrestrial surveys in 2005 and 2006. Additional terrestrial surveys were made in 2016, and while a notable amount of additional clearing had been done the species on the island remain the same. Many of the plants were found in more than one habitat. The plant communities can be divided into those on the most exposed areas of the coastline, the beach community, the wetland communities, the windward vegetation and the less exposed portions of the site. There is also a small landscaped area from around the existing buildings on the site. The locally listed rare and endangered Man:malaria nivosa was noted on the exposed rocky cliffs within the exposed coastal vegetation. It was not as prevalent as Turks head cactus. Malpighia woodinuyanna, another locally listed rare and endangered plant may be present but was not seen during the surveys.

Deer, and goats were noted during the survey in the dense bush in 2004 but only deer were noted in 2005 and 2006. Numerous mice and rats were noted on every visit and did not seem afraid of humans. No rats were noted in 2016. Reptiles were abundant and tree anoles (Anolis cristatellus), grass anoles (Anolis pulchellus), barred anoles (Anolis stratulus), dwarf geckos (Thecadactylus sp), and common ground lizards (Sphaerodactylus macrolepis) were seen. Worm lizards (Amphisbaena fenestrata) have been reported but were not encountered. Puerto Rican racers (Alsophis portoricensis) were seen on every site visit including in 2016 and appear in the highest density around the salt ponds. The St. Thomas tree boa (Epicrates monensis granti) is also present and two were seen during the surveys in May of 2006. One in the vegetation near the modem housing complex and one in the trees near Christmas Cove. 6.08 Wetlands The U.S. Army Corps of Engineers defines wetlands as "those areas that are periodically inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, bogs, marshes and similar areas." (U.S. Army Corps of Engineers, 1986). In March 2004 Amy Claire Dempsey of Bioimpact, Inc., delineated the wetlands on the island of Great St. James in accordance to the 1987 Wetland Delineation Manual. 52 EFTA00802776 Figure 6.08.1 The six salt ponds on Great St. James POND 1 Pond 1 is located on the northeastern point of the island. The pond is surrounded by cobbled beaches to the north and west and steep hillsides to the east. The southern side has the gentlest rise from the pond and has the greatest area of wetland outside the area that typically has standing water. Cobbles extend down into the pond on the two beach sides and the cobbles have green stains. The pond has a monoculture of black mangroves, A viennia genninans. 53 EFTA00802777 POND 1 POND 2 Pond 2 is located on the northwestern point of the island. The pond is surrounded by a cobble beach to the north and steep hill sides to the south, east and west. There is a rock wall built across the eastern corner of the pond. The pond is almost a monoculture of black mangrove, Aviennia germinal's. Only a few white mangroves, Laguncularia racemosa were encountered along the shore side. This wetland is closest to the temporary barge landing. The access roadway is 100' from the edge of this wetland. 54 EFTA00802778 POND 2 POND 2 POND 3 Pond 3 is a depressional area off Christmas Cove on the western side of the island. It is located to the north of a larger salt pond. This wetland is primarily surrounded by manchineel (Hippomane manchineel). It appears that this pond only occasionally holds water. There is a lot of dead wood within this depression. POND 4 Pond 4 is located behind the cobble beach berm off Christmas Cove. The western side of the pond is bordered by a cobble beach and cobbles spill down into the pond. The northern, southern and eastern sides of the pond are bordered by steep hillsides. The wetland forms a narrow strip around the pond. The pond is a monoculture of buttonwood mangroves, Conocarpus erectus. 55 EFTA00802779 POND 5 POND 4 Pond 5 is located on the eastern side of the island behind a cobble beach. Its eastern border is a mixture of sand and cobble spilling over from the beach, and the northern, southern and western border are steep hillsides. The northern end of the pond has been filled with coral rubble which was thrown over into the pond during stormd. The pond is surrounded by buttonwood mangroves, Conocarpus erectus and the ground cover Sesuvium portulacastrurn is present along the eastern side. POND 5 56 EFTA00802780 POND 5 POND 6 Pond 6 is located to the south of pond 5 on the other side of a knoll. It is fringed by the shoreline community on its eastern and northern sides. Steep hillsides surround the pond to the south and west. White mangroves (Laguncularia racemosa) are the dominant species surrounding the pond. The southeastern landing is closest to this pond. The access road already exist and its use will not impact the wetland. Wetland Impact The roadway to the southern landing site was elevated during the flooding associated with hurricanes Irma and Maria and the subsequent heavy rains. The elevating of the roadway resulted in fill being placed into the edge of the wetland and into the low lying area adjacent to it. Fill has been pulled back from the southern side of the wetland and the edges of the wetland and low-lying area and stabilized with riprap. Large boulders covered with filter fabric have been placed beneath the roadway to allow the flow of water to and from the wetland. During periods of high seas water flows over the shoreline to the north and flows across the neck of the peninsula in to the saltpond. This function has been restored. 57 EFTA00802781 White mangrove seeds have been scattered in the pond and seedling are being to grow. These will be monitored and a report will be sent to the US Army Corps showing the survival of 20 mangroves in April of 2019. Figure 6.08.1 Areas of wetland Encroachment. The wetland is shown in green and the areas of wetland encroachment are shown in red and the area fill into the drainage into the wetland is shown in blue. The fill material has been completely pulled out of the wetland and the ground restore to the proper elevation. 58 EFTA00802782 The fill has all been removed. The recovery of the mangroves and vegetation since the storm is evident in June of 2018. Before and after hurricanes Irma and Maria. 6.09 RARE AND ENDANGERED SPECIES All three rare or endangered sea turtle species; hawksbill turtles (Eretmochelys imbricata) green turtles (Chelonia mydas) and leatherback turtles (Ermochelys coriacea) occur in the area but neither of the docks or landing sites are turtle nesting beaches. NOAA's Sea Turtle and Smalltooth Sawfish Construction Conditions will be followed as well as NOAA's Vessel Strike Avoidance Measures and Reporting for Mariners in order to protect these species. Acoustic impacts are also a potential impact to sea turtle species therefore a vibratory hammer will be used during construction to minimize this impact and if necessary pile will be socketed rather than impact driven. The use of an impact hammer is not proposed. The marine habitats around Great St. James have abundant coral and seagrass resources. There are numerous ESA listed corals species near the proposed dock locations. 59 EFTA00802783 Acropora palmata, A. cerviconzis, Orbicella amzularis, O. franksi and 0. faveolata as well as Dendrogyra cylindrus are found off all the cobble beaches from which the proposed docks and barge landings are proposed. At the northern temporary barge landing site, these corals are located primarily to the east where there are coral boulders and coral rubble. There are few located on the shoreline cobble which extends out to a depth of 6.5ft to 7ft. There are several small Acropora palmata and several Orbicella ammlaris on the nearshore cobble and the presence of these species as well as several Porites astreoides dictated the location of the barge landing. The proposed temporary barge landing position avoids all coral and the landing approach is over sparse seagrass. The western dock location is off a cobble beach between to areas of emergent bedrock and boulders. Acropora palmata occur on the emergent bedrock to the north as well as on the cobble. Offshore the seafloor quickly gives way to exposed pavement and there is a long linear depression right offshore. An old piling lies within this area. The fractured pavement then extends to a depth of approximately 11.5ft offshore over the next 130ft. The area has some widely-scattered boulders and patchy coral colonization. There are scattered ESA corals including Orbicella and Dendrogyra. During the first survey, there was a very large Acropora cervicornis immediately seaward of where the old piling lay near shore. However, upon the next visit by the island it was noted that an old boat was tied nearshore apparently attached to the old piling. During a dive several weeks later it was noted that the boat was gone and the large A. cerviconzis had been badly broken. The location of the ESA species has dictated the location of the dock. Approximately 75 corals will require relocation to minimize impact, but no listed corals will need relocation. The southern dock also extends from a cobble beach which gives was to rock pavement and has emergent bedrock and boulders on either side of the beach. There are Acropora to the east and farther to the south on the bedrock and boulders. There are Orbicella and Dendrogyra within the embayment and their locations have dictated the location of the dock. The dock avoids all ESA listed corals but will require the relocation of approximately 75 corals. The island is known to be habitat to the St. Thomas Tree Boa (Epicrates monensis granti) that is a federally listed rare and endangered species. The boa as well as another species of snake were seen during the field studies. There will be special corridors and preservation areas set aside on the island for these species. The access ways to the western and southern docks already exist, but access will need to be developed to the temporary barge landing. Vegetation along this access will be cleared by hand to limit impacts to the tree boas. A tree boa mitigation plan is found in Appendix D. 6.10 Air Quality All of St. John and St. Thomas is designated Class II by the Environmental Protection Agency in compliance with National Ambient Air Quality Standards. In Class II air quality regions, the following air pollutants are regulated; open burning, visible air 60 EFTA00802784 contaminants, particulate matter emissions, volatile petroleum products, sulfur compounds, and internal combustion engine exhaust (Virgin Islands Code Rules and Regulations). There will be a slight increase in air emissions during the use of heavy equipment for pile socketing/vibra-hammering. Once the docks are complete air quality will be impacted by the periodic vessel visitations. The dock will have a negligible impact on air quality. 7.00 IMPACTS ON THE HUMAN ENVIRONMENT 7.01 Land and Water Use Plans The property is zoned R-1, Residential Low density. The proposed structures are intended to provide access to the residence on the offshore cay. 7.02 Visual Impact The structures are proposed for the privately held offshore cay. The docks are all low profile and will have turtle friendly solar lighting for visibility at night. Due to the location of the cay the dock structures will only be visible from boats and from Little St. James. 7.03 Impact on Public Services 7.03a Water There will be no water service to the docks or landing. 7.03b Sewage Treatment and Disposal There will no sewage associated with the docks or landing. 7.03c Solid Waste Disposal The construction of the docks will have minimal waste production. The wood and decking which will be removed from the dock which will be demolished will be recycled and reused on the island and the piles will be used in landscaping. The ramp for the temporary barge landing will not be removed unless required by the agencies. Ramp would not be used unless there were an emergency and the southern barge ramp was unusable. If the barge ramp is removed the concrete would be broken up and buried in the islands disposal site. It will have no impact on public waste disposal facilities. 7.03d Roads, Traffic and Parking The docks and landing are associated with an offshore cay and therefore have no impact on public roads, traffic or parking. The roads on GSJ are private and are not public roadways. The construction of the barge ramp, the docks and their use will not affect 62 EFTA00802785 public roads. The island roadways are hard packed dirt roadways and most traffic on the roadways are smaller gators, and golf carts to transport employees. Upland development including the roadways and roadway stabilization is discussed in the Master Plan application. 7.03e Electricity The docks and landing will use turtle friendly solar lighting. 7.03f Schools The construction of the 2 docks and landing will have no impact on schools. 7.03g Fire and Police Protection The development of the access docks and landing will improve fire department and police access to the cay in the case of an emergency. 7.03h Health The construction of these features will not increase the use of the public health facilities. The construction of these docks and the landing will make it easier for emergency health transportation to and from the cay. 7.04 Social Impacts The construction of the docks and barge landing are proposed for a private offshore cay with the intention to provide access to the owner and his staff. These activities on the privately held island will not affect the islands of St. Thomas or St. John. The western dock has been located as far north in Christmas Cove as possible while minimizing benthic impacts. The bay is heavily used because it is an excellent mooring area and therefore it is also a suitable location for a dock. Vessels will only approach the dock at low speeds. Signage will be placed on the dock noting that it is an active private dock and to use caution if swimming or snorkeling near the dock. Most of the activity in Christmas Cove occurs to the south. The owner access to the island and the public use of the moorings should be able to co-exist. 7.05 Economic Impact The private docks and landing are not revenue producing. The permitting of the structures will result in the payment of submerge land fees by the applicant. 63 EFTA00802786 7.06 Impacts on Historical and Archeological Resources The proposed structures are in the shallow waters around Great St. James. Detailed surveys were done as part of the benthic assessment. An old dislodged pile was noted near the shoreline and one further offshore. These are being avoided due to coral colonization. A request for a clearance letter has been sent to SHPO. A MOU is in place for the upland portions of the island. 7.07 Recreational Use People typically do not visit either the northern beach area or the southeastern dock site. The Christmas Cove is however periodically visited by boaters and visitors who picnic on the beach or walk on the shoreline. The docks will not interfere with public access to the shoreline and the public will continue to enjoy free egress within the 50' set back. 7.08 Waste Disposal The dock will not create solid waste, any trash from vessels will be disposed of in receptacles on the island and hauled off with the other trash. The temporary barge landing and access dock/barge land will facilitate the removal of trash form the island. 7.09 Accidental Spills No fueling or repair will be allowed at the docks. The docks and landing will keep emergency spill kits nearby so that in the event of an inadvertent release from a vessel it can be quickly contained. 7.10 Potential Adverse Effects Which Cannot Be Avoided The project will result in the alteration of an offshore cay and development on shorelines which have previously been undeveloped. There will be water quality impacts due to pile installation, but if the turbidity control and monitoring is implemented as proposed impacts should be minimized and short term. There are corals within the footprints and impact area of the construction and these will be transplanted prior to construction (Mitigation Plan Appendix B). The docks have been designed so that the vessels are in deeper areas and bottom disturbance should be minimized. Christmas Cove is already heavily utilized by boat traffic, so the additional vessel use should be negligible. Neither the northern barge landing or southern site are typically used by boaters and this will result in increased boat traffic to both. 8.00 Mitigation Plans To abate and minimize environmental impacts the following mitigation and monitoring plans are proposed. 64 EFTA00802787 Coral Relocation and Mitigation Plan Appendix B Water Quality Monitoring Plan Appendix C Tree Boa Protection Plan Appendix D The applicant will ensure that 20 white mangrove saplings (Laguncularia racemosa) have become established in the southern wetland. A report will be filed with US Army Corps of Engineers showing the survival of these trees in 2019. 9.00 Alternatives to Proposed Action A siting study was done around the entire island. All potentially usable docking sites were investigated. Site accessibility was one of the most restrictive issues. The existing dock which is in Shallow Bay is far too shallow and its use has result in damage to the once dense Thalassia testudinum beds within the bay. Although barges have been landed in the bay it has resulted in damage to the shallow seagrass beds. The bay is only 4ft deep 600ft off shore. The dock in its current configuration is not approved by the USACE and the USACE has requested its removal. It was not permitted due to the shallowness of the bay and the potential impacts to the shallow seagrass beds. Shallow Bay is also not suitable for barge landing. In order to provide boat access and barge access to the island a new structure or structures are necessary. Many of the shorelines are inaccessible due to steepness. The most southern embayment could support a dock with similar impacts as the selected sites, access to this embayment was extremely difficult and would require significant cutting and filling which would result in increased environmental impact. On Christmas Cove there are several areas where a dock could be extended from the shoreline with similar potential impacts as the proposed dock, however, the areas further to the south would have greater seagrass impact, could impact the salt pond and would have a significant impact on the public use of Christmas Cove since the dock would extend into the highly used mooring area. The area selected in Christmas Cove is at the far end of the cove and therefore will not result in boat traffic through the mooring field. 65 EFTA00802788 Alternative Analysis for Dock Locations Great St Janes - cShailove ESA 0 t a , •--- .

The existing dock is in too shallow of a bay and is not federally permitted in its current configuration. The development of a more suitable dock and barge landing is in the best interest of the environment to abate impacts which are occurring due to the shallowness of the bay which is now being used. The development of adequate facilities for island access and the continuing requirements for the removal of trash and delivery of supplies is in the best long-term interest for man's environment. 11.00 REFERENCES Literature Cited Bowden, E. et. al., 1969.

MONITORING REQUIREMENTS XI. LONG-TERM MANAGEMENT PLAN XII. ADAPTIVE MANAGEMENT PLAN XIII. FINANCIAL ASSURANCES This plan follows the compensatory mitigation guidelines as set forth in 40 CFR Part 230, Compensatory Mitigation for Loses of Aquatic Resources: Final Rule. The fundamental objective of compensatory mitigation is to offset environmental losses resulting from unavoidable impacts to the waters of the United States authorized by DA permits. EFTA00802815 I. INTRODUCTION Great St. Jim, LLC is seeking to construct two docks, one of which is a combination dock/ barge landing, and a temporary barge landing to provide access to Great St. James Island. There is currently a small pile-supported dock located within Shallow Bay on the north side of the island. The bay is very shallow and vessels accessing the dock have damaged the shallow seagrass beds within the bay. At one time, there had been a concrete bulkhead at the shoreline with a small floating dock. The previous owner submitted an application for the existing dock which was approved by DPNR's Division of Coastal Zone Management, but was not approved by the U.S. Army Corps of Engineers due to objections by National Marine Fisheries because of the shallowness of the bay. The dock was constructed by the previous owner despite not receiving the federal permit and notices were issued by the USACE requesting the removal of the unpermitted structure. The dock however was never removed. The applicant, understands the issues with the existing dock and is proposing to remove the dock as soon as another dock is constructed and usable. A detailed study was done around the entire island to determine suitable locations for dock location. All ESA listed corals were located and docks and barge landings were designed to avoid these corals. A temporary barge landing is being proposed on the northwestern facing beach. This site is to the west of the salt pond and the associated wetlands. This a shoreline ramp which is 25 feet (ft) wide and 40ft in length extends to the Mean Water Line. The landing is free of both coral and seagrass colonization. The landing is excellent for short term transfer of material or equipment. The site is well protected from normal wave action but is periodically impacted by wave action from ferries which travel through current cut between Great St. James and St. Thomas. The wakes from these vessels make it an unattractive site for mooring a barge for any length of time at the site. This landing can be quickly constructed and utilized while the combination dock and barge landing on the southeastern side of the island is constructed. The western dock is proposed on the northern end of Christmas Cove. Historically there was a dock in this location and there are still old concrete piles lying in the shallows of this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft from mean low water (MLW) and I93ft from mean high water (MHW). The dock extends beyond the nearshore hardbottom to a depth of 15ft out in the uncolonized sand to allow for safe dockage for deeper vessels. EFTA00802816 The southern dock is located off the point closest to Little St. James. The dock is "L" shaped and is 20ft wide (to allow for barge landing) and 150ft in length extending 141ft from MLW and 148ft from MHW, the "L" then turns east and extends 100ft by 20ft. A wave attenuating/reef creating system is proposed beneath the dock which will allow for more protected docking inside the dock when seas from the south are rough. The dock has 9ft of water depth of the southern end and 7ft to 8ft on the inside of the "L". The dock has been designed so that barges can approach and land on the end of the dock while vessels can dock along the "L". REASON FOR MITIGATION The marine habitats around Great St. James have abundant coral and seagrass resources. There are numerous ESA listed corals species near the proposed dock locations. Acropora palmata, Acropora. cervicornis, Orbicella annularis, Orbicella franksi and Orbicella faveolata as well as Dendrogyra cylindrus are found off all the beach from which the proposed docks and barge landings are planned. At the northern temporary barge landing site, these corals are located primarily to the west in an area of coral boulders and coral rubble. However, there are several small A. palmata and several 0. amiularis located on the shoreline cobble which extends out to a depth of 6.5ft. The presence of these species as well as several non-ESA listed Porites astreoides has dictated the location of the ramp. The proposed temporary barge landing position avoids all coral and seagrass resources. Location of the western dock has a cobble beach between two areas of emergent bedrock and boulders. A. palmata occur on the emergent bedrock to the north. Offshore the seafloor quickly gives way to exposed pavement. There is a long linear depression right offshore and an old piling lies within this area. The fractured pavement then extends to approximately 11.5ft of depth over the next 100ft heading offshore. The area has some widely-scattered boulders and patchy coral colonization. There are scattered ESA corals including Orbicella and Dendrogyra. During the first survey, there was a very large A. palrnata colony immediately seaward of where the old piling lay near shore. However, upon the next visit by the island it was noted that an old boat was tied nearshore apparently attached to the old piling. During a dive, several weeks later it was noted that the boat was gone and the large A. cervicornis had been badly broken. The location of all the ESA species has dictated the location of the dock. Approximately 75 corals will require relocation to minimize impact but no listed corals will need relocation. The southern dock also extends from a cobble beach which gives way to rock pavement and has emergent bedrock and boulders on either side of the beach. There are Acropora colonies to the east and farther to the south on the bedrock and boulders. There are Orbicella and Dendrogyra within the embayment and their locations have dictated the location of the dock. The dock avoids all ESA listed corals but will require the relocation of approximately 75 corals. EFTA00802817 II. MITIGATION OBJECTIVES It is the objective of this mitigation project to limit the amount of coral and coral habitat that is lost as a result of the dock and barge access construction. All of the coral, sponge, and sessile life forms within the footprint of the facility or which might be potentially impacted during construction or operation will be transplanted. Approximately one hundred and fifty (150) corals will be relocated. III. SITE SELECTION The recipient sites were selected due to their being similar environments and being close to the mitigation site. The corals from the Christmas Cove site will be located to the north onto the adjacent hardbottom areas which are at equivalent depths. The corals from the southeastern dock site will be transplanted to the hardbottoms to the south which are at equivalent depths. IV. SITE PROTECTION INSTRUMENT The applicant will prepare an easement setting these areas aside as protected areas. V. BASELINE INFORMATION Benthic Habitat Description General Sandy beaches, cobble beaches and steep rocky shorelines surround great St. James Island. All three of the proposed dock and barge landing sites will extend from cobble beaches. The northern shore where the temporary barge landing is proposed has cobble which extends down to a depth of approximately 7ft and has sparse seagrass colonization within the barge approach. There are scattered corals in the bay to the east and dense seagrasses offshore beyond the landing site. The cobble within the landing site is only colonized by fire coral. The emergent bed rock to both the east and west sides of the bay are colonized by corals species including ESA corals. The northern portion of Christmas Cove where the Access Dock is located has emergent bedrock to either side of the small embayment which are colonized by coral and sponge species. Rock pavement and scattered boulders extends offshore to a depth of I I.5ft where it gives way to a sandy bottom. Corals and sponges colonize the rock pavement and scattered boulders. There is seagrass off shore but it begins beyond the terminus of the proposed dock. The southern facing dock is off a cobble beach between to rocky shorelines. There is rock pavement extending off shore and then broken rock pavement further out. Corals and sponges colonized the rock pavement. EFTA00802818 ESA listed coral species are found at all three locations and the Nassau Grouper (Epinephelus striatus) was seen off both the Christmas Cove and southern dock site. Methods The NOS St. John and St. Thomas Habitat map Tile 16 (Figure 6.06.1) of the Great St. James area shows the colonized rock pavement and bedrock as well as the offshore seagrass beds. The seagrass beds are not as continuous near the shoreline as shown, and the offshore area at both Christmas Cove and the southern dock site are colonized pavement rather than bedrock right off the cobble beaches and on the northern facing beach the pavement doesn't extend completely across the bay as shown. Surveys were done on Scuba and Acropora palmata and Acropora cerviconds, Dendrogyra cylindrus, Orbicella annularis, Orbicella faveolata, Orbicella franksi, and Mycetophyllia ferox were mapped so that they could be avoided. Habitat boundaries were marked with GPS and/or by the surveyor for accuracy. Percent abundance was determined along transect lines and utilizing a meter square. -2•••• 0:1•••••••••••••••••+ MIns••••a••••• gr. 1=12 Figure 1. NOAA Benthic Habitat Map • PE • MO la, Benthic Resources NM. Great St. James is located off Water Point on the eastern end of St. Thomas. This oddly shaped island has a variety of shoreline types and six salt pond/wetland habitats. There is a well-protected shallow northern bay where an existing dock is located. Shallow Bay is colonized by seagrass which includes Thalassia testudinum, Syringodium Monne and Halodule wrightii. Recently the sea vine Halophila stipulacea has colonized areas which have been disturbed. The densest seagrass beds once lay near shore and to the east of the dock. Over the last several years these beds have been highly disturbed. The peninsula to the east of this point is surrounded by rocky headlands and is a very exposed EFTA00802819 environment. The rocky cliffs extend below the sea surface and due to the intense wave action, the shallowest areas are not colonized. By a depth of 8ft-10ft the rocky substrate becomes colonized by a wide variety of corals and sponges. The slope is steep offshore and the water reaches a depth of 40ft to 50ft relatively close to shore. The rocky slope gives way to a cobble then sand bottom and there are sparse to moderately dense seagrass beds that extend seaward. The rocky shoreline continues around to the south, with coral colonized nearshore hardbottom and seagrass colonized sand and cobble further offshore. There are two cobble beaches further to the south divided by a small rocky headland, there is some colonized beach rock nearshore and shallow seagrass beds off shore. The shoreline facing St. James Cut and the southern end of the island is rocky. This area has limited coral colonization in the inner tidal zone giving way to an abundant diverse coral community on the submerged rocky slopes. The rock is relatively steep with numerous grottos, and caves, and gives way to a cobble/sand bottom at around 20ft to 25ft. There are moderate to dense seagrass beds off shore. The Stragglers lay off the southern most point of the cay, and like the southern shoreline of the island there is minimal colonization in the inner tidal areas of the emergent rocks with coral colonization and diversity increasing with depth. The western shoreline is well protected and is a combination of rock and sandy beach. The water deepens much more gradually on this side of the island. In the areas with rock along the shoreline are colonized by corals and sponges. The less colonized inner tidal area is much less defined here due to the more protected nature of the site. Within Christmas Cove there is a rock groin like structure that extends into the bay near the center of the embayment. Offshore to the north of the groin there is a small beach rock shelf and then a strip of uncolonized sand before sparse to moderately dense seagrass beds begin. The site is currently used by boats anchoring adjacent to the beach. To the south of the groin there is a beach rock shelf with moderate coral colonization which falls off to depth of over 6ft only 40ft from shore and there is a board area of uncolonized sand out to a depth of 10ft before reaching the moderately dense seagrass beds and open sandy plains. The shoreline becomes rocky again to the north along Current Cut and the area is more subject to wave and current action. There is coral colonization along the rocky shoreline and on the rock pavement that extends off shore. The north-facing bay to the east of Current Cut is a mixture of cobble and rocky shoreline with a small sandy beach in front of the salt pond. Where rock is present there is coral colonization and in the open sandy areas there is moderate to dense seagrass colonization. The temporary barge landing is located at the western end of the north-west bay. The landing. The beach is cobble and the cobbles extend out to a depth of 7ft at the landing site. The landing site contains some scattered Millepora complanata, but no hard-coral species. There are scattered corals to the east in the cobble including a few Orbicella amudaris and Acropora palmata. Porites astreoides is the most abundant coral in the cobble to the east. The location for the barge ramp was chosen due to the presence of corals and coral colonized boulders throughout the bay to the east. To the east in the bay there are numerous Orbicella annularis, O. faveolata and Dendrogyra cylindrus as well as other coral species. Offshore there are dense seagrass beds consisting of 77wlassia testudinum and Syringodiumfiliforme, however these are greater than the 75ft off shore EFTA00802820 which the barge will extend while moored. There very sparse Syringodium colonization within the barge approach, representing less than 5% bottom coverage. Northern site Figure 2. Benthic habitats at the bare landing. obble in footprint of barge mooring site eagrass offshore well beyond the cobble EFTA00802821 approach Sparse seagrass in the immediate barge The access dock in Christmas Cove is near the location of an old historic dock. The beach is a mixture of sand and cobble. There is rock pavement extending offshore and there is an area of cobbles in the center of this area which is uncolonized out to a depth of 5ft. The rock pavement has various depressions and breaks and within one of these depression is a pile from the old concrete dock. Beyond the depression, the water deepens quickly out to a depth of 12ft. The rock pavement is colonized by Diplona strigosa, D. labyrinthifonnis, Orbicella annularis, 0. franksi, Porites astreoides, P. porites, Dendrogyra cylindrus, Gorgonia sp. and Millepora sp. and the sponges Aplysinafidva, Amphimedon compressa and Ircinia sp. Coral colonization increases on either end of the small embayment and with depth. Beyond the nearshore hard bottom, approximately 120ft off shore the bottom becomes sandy. There is a minimally colonized area before the bottom begins to become colonized by Syringodiztmfilifonne which slowly grades into a mixed bed of Thalassia testitudium and Syringodium. The exotic seavine Halophila stipulacea is also present. This seavine was not present in 2006. There was a very large intact Acropora cerviconzis in the center of the bay just off the old dock piling in the depression early in 2016. However, a boat moored on the old piling and on a subsequent dive the Acropora was found completely broken. Pieces of this Acropora remain. There are Acropora palmata in the shallows to the north of the proposed dock location both on the cobble and bedrock. EFTA00802822 The bottom formation is dead visible this •hoto• a h. Fi tire 3.

Like the other two bays there is cobble on the shoreline which extends into the sea to 2ft to 4ft of water depth. Offshore there is pavement with boulders and odd rock formation. The area is colonized by scattered corals which are most abundant on the boulders. Orbicella annulans, O. franksi, O. faveolata, Dendrogyra cylindrus, Porites astreoides, P. porites, Diplona strigosa, D. clivosa.

MITIGATION WORK PLAN CORALS Prior to the start of the relocation project the footprint of the docks and the predicted impact zone will be marked on the seafloor using small pin flags. Any coral or boulder which partially extends into this zone will be relocated. Individual corals that are attached to the near shore hardbottom will be removed with chisels. These corals will be collected in bins and carried to recipient site. These corals will be fixed in placed in their new locations with two-part underwater epoxy, which sets in a matter of minutes (Splashzone). The base of the coral will be carefully cleaned with a wire brush and the new substrate will be cleaned to remove algae and any other material which might interfere with the adhesion of the epoxy or cement. The coral will be carefully placed and held until the epoxy starts to set. Divers will then collect those corals and sessile invertebrates that colonize cobbles and rocks within the dock footprint that are of a small enough size to allow hand carrying. These are cobbles and boulders that are in a range of I ft2 to 2.5ft2. These corals are usually growing on pieces of coral rubble. Divers will wear disposable gloves while working with corals minimize touching live tissue and keep any coral that appear unhealthy or diseased away from other corals. Corals which appear to be diseased will be marked, and not transplanted to the recipient area to minimize the potential of the spread of disease to the recipient site. The diseased corals will be photographed and will be addressed in the baseline report for the transplant identifying the size and location of each individual colony. If a coral is handled that appears unhealthy or diseased gloves will be changed prior to working with other corals. The I ft2 to 1.5112 corals will be placed in underwater bins and carried by divers to the recipient sites. The larger corals will be placed directly on a transport tray. Once the tray is full it will be lifted by lift bags and walked to the relocation site. Once on site the tray will be lowered near the seafloor and divers will remove the corals from the tray. The coral will be placed in the recipient site in such a fashion that the rock is stable and will not be subject to movement. This will be done by digging a depression in the sand to rebury the base to the same depth as it was prior to transplant. Care will be taken to make sure no live tissue is buried or too close to the sand that it may become buried. If possible if hard substrate or other larger rocks or rubble is found the coral base will be attached to it with "Splashzone" two-part underwater epoxy. Care will be taken so that these transplanted materials will not impact existing organisms at the transplant site. Splashzone epoxy is used because it is approved for drinking water systems by EPA. This epoxy does not leach any harmful chemicals into the water. This epoxy also does not create the temperature change which occurs with hydraulic cement. For corals and larger coral colonized rocks, those greater than 2.5ft2, lift bags, and ropes will be utilized. divers will lift and transport larger corals, and coral colonized rocks then slowly carry the organisms to the transport tray. Again when the tray is full it will be EFTA00802826 lifted and walked to the recipient site. When attaching the corals to the lift bags ropes will be placed so that they avoid live coral tissue. If necessary, a plate may be placed underneath corals so that it lifted without the tissue being impacted by the ropes. The coral boulders and larger rocks will be placed in the recipient site in such a fashion that the rock is stable which may require some excavation into the sand to create a depression for the previously buried part of the rock. Care will be taken so that these transplanted materials will not impact existing organisms at the recipient site. Care will be taken to place corals in the same orientation and depth as they were in their original locations. COMPENSATORY MITIGATION To mitigate for impacts that cannot be avoided a special reef building system will be placed beneath the southeastern dock. This system serves not only as a wave attenuator by provides additional substrate to allow for colonization beneath the dock. Grated decking will be used on the dock to facilitate light transmission. .... .2 0 0. .. ID • • % (i),(;) • • 1•`); II < • )0 • • • ...a ....,• • , Ilt•MB 4 • v za .,•• • • •I • >0 A% I • se•Ni.

MAINTENACE PLAN Divers will survey the recipient site on a bi-weekly basis for the first 2 months after the transplant to ensure that the corals have not become unattached or shifted. If for any reason the corals become loose or move they will be re-situated and or reattached. After the first two months the corals will be monitored on a monthly basis for the first year and then on a bi-monthly basis for the following 2 years then every 6 months for year 4 and 5 after the transplant. During each monitoring event divers will make sure that the rocks have remained stable and not shifted, and that corals and sponges have not come loose. If necessary corals will be repositioned and re-attached. IX. ECOLOGICAL PEFORMANCE STANDARDS The object of this mitigation is to minimize impact to benthic resources which provide high quality habitat to marine species. In order to objectively evaluate the mitigation project, ecological performance standards must be established. The performance standards will include viability of the transplanted corals and sponges and relocated seagrass. It is the intent of this transplanting program to obtain a minimum of 80% survival of the transplanted corals and sponges. Great St. Jim, LLC is committed to put forth the greatest effort to see that the relocation is successful and that they obtain the greatest potential survival of transplanted organisms. X. MONITORING REQUIREMENTS Monitoring the compensatory mitigation project site is necessary to determine if the project is meeting its performance standards, and to determine if adaptive measures are necessary to ensure that the project does meet its objectives. As per the guidelines set forth in §230.96 Monitoring the mitigation project will be monitored for a minimum period of 5 years. In total twenty-five transplanted corals at each site will be marked with numbered tags for monitoring. The tags will be maintained throughout the 5 year monitoring period. The corals will be surveyed for percent live tissue, color, algal growth and indicators of disease and photographed on a monthly basis for the first twelve (12) months. Corals will then be monitored on a bi-monthly basis for the follow 2 years and then every 6 months for years 4 and 5 after the transplant. The percent live tissue, color, stress, surround algal growth, algal growth on dead areas of tissue and any signs of disease for each monitored coral will be noted in the reports. If at any time during the monitoring degradation of the corals is noted, degradation being defined as tissue loss, indication of disease, color change, excessive algal growth or notable mucus, affected corals will be compared to those within the other monitoring quadrats and corals in areas outside the impact area of the project. This information will be used to determine whether the degradation of the corals is due to the transplant, EFTA00802828 activities related to construction or resort or due to natural phenomena (such as wide spread bleaching). If the corals appear to be stress due to the transplant, the reason for the demise will be assessed, poor positioning, sand scour, light attenuation, etc. If necessary, the coral or sponge will be repositioned. Every effort will be made to save the coral or sponge. If the degradation is seen both in the project area non-transplanted corals and the transplanted corals, the reason will be assessed for the demise. If the source of the impact cannot be readily assessed by the monitoring being undertaken, the monitor will work with NMFS and VI Fish and Wildlife and the other resource agencies to expand the monitoring so that the source of the impact can be identified. In order to monitor the success of the reef creating system under the southeastern dock, it will be monitored concurrently with the corals and a detailed photographic recorded will be kept depicting colonization, survival and growth of coral and sponge species. The monitoring results will be delivered to the agencies within two weeks of the monitoring period. If negative impacts are noted the agency will be notified by phone and by email within 24 hours. The agencies will be apprised of what steps are being taken to identify the impact and rectify the problem. The agencies will be provided a detailed report on the steps that are taken and the results of those actions. XI. LONG TERM MANAGEMENT PLAN Great St. Jim, LLC is committed to the survival of the transplanted coral species and the success of the reef building system and will make every effort to ensure that both are a success. XII. ADAPTIVE MANAGEMENT PLAN In the event that there are difficulties with the mitigation or if the mitigation is deemed unsuccessful as planned, Great St. Jim, LLC is prepared to take additional steps to see that compensatory mitigation goal is achieved. If necessary, extended monitoring and maintenance or additional marking of the sites will be undertaken in order to meet the mitigation goal. If the mitigation goal of 80% survival at the end of five years is not met, the applicant will prepare a detailed report of why the mitigation was not successful. Great St. Jim, LLC will meet with the permitting agencies to determine the additional compensatory mitigation needed to meet the mitigation goal. XIII. FINANCIAL ASSURANCES Great St. Jim, LLC will secure a performance bond in the amount of the cost mitigation program and subsequent monitoring throughout the implementation and monitoring period or provide another form of acceptable financial assurance. The bond will follow the guidelines set out by the U.S. Army Corps of Engineers Regulatory Guidance Letter EFTA00802829 No. 50-1, 14 February 2005, SUBJECT: Guidance on the Use of Financial Assurances, and Suggested Language for Special Conditions for Department of the Army Permits Requiring Performance Bonds. EFTA00802830 APPENCIX C ENVIRONMENTAL AND WATER QUALITY MONITORING PLAN FOR THE CONSTRUCTION OF A TEMPORARY BARGE LANDING AND TWO DOCKS ON GREAT ST. JAMES, U.S. VIRGIN ISLANDS INTRODUCTION The following is the proposed monitoring program for the construction of a temporary barge ramp and two docks on the island of Little St. James. The purpose of this monitoring plan is to evaluate and minimize the impact of the proposed construction on marine water quality and the benthic community. Great St. Jim, LLC is seeking to construct two docks, one of which is a combination dock/ barge landing, and a temporary barge landing to provide access to Great St. James Island. The marine construction will consist of the vibra-hamming or socketingof piles and the placement of docks. The impact pile driving or vibra-hammer driving will have a minimal potential for creating turbidity. However, where rock encountered it is possible that piles may need to be socketed. Pile socketing greatly increases the potential for turbidity, and creates large volumes of rock flour. Based on observations in the field a number of piles may require socketing. Turbidity barriers (silt curtains) will be installed surrounding all pile driving/socketing activities. The curtains will serve not only to maintain turbidity created by pile driving but will also contain floating debris within the project area. The turbidity barriers will be properly installed and will extend to within 1 ft. of the seafloor where piles are driven. If piles require socketing, curtains will extend to the seafloor and a double set will be deployed. ESTABLISHMENT OF BASELINE CONDITIONS AND SAMPLING POINTS Prior to the start of any construction activities a baseline of existing conditions will be assessed. Baseline samples will be conducted over a two-month period. The sampling locations have been established to encompass the area most likely to be potentially impacted during construction. The baseline samples sites are shown in Figures 1 and 2. No monitoring should be necessary for the temporary barge landing. Baseline samples will be tested for secchi depth and turbidity expressed as NTU. As part of the baseline sampling, sampling during normal and storm conditions will be completed prior to project construction to determine the natural range in turbidity and duration of elevated turbidity levels to which corals in the area are naturally exposed. Samples will also be taken after large rainfall events which result in an influx of runoff to determine the existing sediment runoff. EFTA00802831 DURING CONSTRUCTION MARINE WATER QUALITY MONITORING During the construction of the docks water quality at the stations in the vicinity of the work will be sampled on a daily basis. Three water samples will be taken 10 meters outside the turbidity barriers surrounding the area of work. Two control samples shown in Figures 1 and 2 will also be sampled. Water quality will be secchi depth and turbidity expressed as NTUs. ACTION TRIGGERS During construction if the water samples show NTUs, or secchi disk readings outside the allowable regulatory limits, the reviewing agencies and the applicant will be notified, in writing within 24 hours of the parameter exceedance. The baseline samples will be utilized to determine if other parameters are elevated above normal background levels. Controls will also be used to determine if the readings are a result of natural phenomena or if the monitoring sample is elevated above the ambient background as a result of the construction project. If it is determined that the elevated turbidity is the result of the construction project, the source of the elevated turbidity will be identified and methods worked out to abate the degradation. Someone will be on hand at the construction site at all times who has the authority to implement sediment control devices or other remedial actions, so that problems can be resolved as quickly as possible. Once the source of the impact is identified, steps will be taken immediately to abate that impact. The action that was taken to resolve the issue, as well as confirmatory sampling data that the degradation has been resolved will be included within the written report to the agencies and GSJ. A monitor will be on site throughout the day during construction activities to ensure that turbidity barriers are adequate maintain and that escaping sediments do not go unabated. REPORTING OF DATA In the event of any emergency or noted degradation in any of the water quality parameters above the allowable or acceptable limits, or any impact to the benthic community the owner and the reviewing agencies will be immediately notified in writing by e-mail. NMFS will be notified immediately of any impact to ESA listed species. Weekly water quality reports will be delivered to all agencies and GSJ throughout the monitoring period. EFTA00802832 Figure 1. Christmas Cove Monitoring Stations and Controls Figure 2. Southeastern monitoring stations and controls EFTA00802833 APPENDIX D VIRGIN ISLANDS TREE BOA MITIGATION PLAN — GREAT ST. JAMES ISLAND ACCESS DOCK CONSTRUCTION Introduction Little St. James island habitat for the Virgin Islands Tree Boa, Epicrates monensis granti and two tree boas were seen in 2006 on the island. The tree boa was listed as Federally Endangered in 1979 and the Virgin Islands Endangered and Indigenous Species Act also protects this species. The tree boa is nocturnal and arboreal, the snake forages at night and seeks shelter during the day. The snakes seek refuge in termite nests, debris piles and under rocks during the day. While the snakes' habitat is listed as dry forests, coastal scrub, moist woodlands, mangroves and rocky cliffs, the snakes can occur in any habitat that allows for off ground movement. The structure of the habitat is more important than the species composition; the dock access had some structure which might be adequate for these species. There is an abundant prey base of lizards on the cay, and there is refugia present; logs and rock piles. Fish and Wildlife states that the snakes are extremely difficult to locate even for an experienced snake biologist, and therefore it must be assumed that the endangered species is present, especially when suitable habitat and refugia are present. Tree boas are known to be present the applicant will make every effort not to take (harass, harm, pursue, shoot, wound, kill, trap, capture, or to attempt to engage in such conduct) any of these endangered species. The dock access way will be cleared by hand and rock piles will be dismantle by hand. All personnel involved in site clearing and site construction will be informed of the potential presence of the snake, and the importance of protecting the snakes. Photographs of the tree boas will be shown to all workers as well as a description of their behavior and habitat. All workers must acknowledge that they understand the importance of protecting this rare and endangered species. The site will be cleared directionally from the existing access way towards the shoreline. If tree boas are encountered, work will be stopped in the area of the snake, and the Division of Fish and Wildlife will be contacted immediately. Ever means necessary will be implemented to prevent harm to the tree boa. The DFW will be notified of any snakes observed or capture. Phone numbers for Fish and Wildlife will be posted at the site to aid in immediate notification. EFTA00802834 APPENDIX E Pearson Sustainable Solutions ARTIFICIAL REEFS "When Marine Ecosystems were first being developed, it was just another artificial reef. However, over time they quickly expanded to areas that entail: wave attenuation, snorkeling reefs, oyster reef restoration, mitigation, shoreline stabilization, personal dock reef, coral reef restoration and to be used as a research tool. Our EcoSystems are a culmination of 22 years worth of work in designing and deploying over 35,000 artificial reefs. Its complex (rugosity) design allows small marine animals to seek shelter and protection from larger predators and is ideal for defusing wave energy above the water line. This allows you to place an ecosystems in a high-wave energy area without worry about a storm event damage. The Florida Limestone rock used replicates natural reef substrate and PH. The EcoSystems create an environment for all marine life to attach and this does include boring animals which was something no other artificial reef out there has been able to do. The pile mounted design, utilizing a Pearson Piling mount system, guarantees the unit will stay upright and not sink into the bottom as well as provide proper flushing and creature mobilization."
