APTIM December, 2019 Aptim Coastal Planning & Engineering of North Carolina, Inc. Executive Summary In 2019, Aptim Coastal Planning & Engineering of North Carolina, Inc. (APTIM) was authorized to provide project management, environmental, geotechnical, engineering and bidding assistance services to the County of Dare (OWNER) to facilitate a one-time maintenance dredging event within Ranges 1-4 of the federally authorized Manteo (Shallowbag) Bay navigation project. In July of 2019 APTIM utilized CATLIN Engineers and Scientists to collect five vibracore samples within or in proximity to the proposed dredging footprint in Shallowbag Bay. APTIM staff were present during the time samples were collected. Vibracores retrieved undisturbed sediment samples to a target depth of at least -14 ft. MLLW. The length of the actual cores depended on water depth. The final depth of recovery varied based on sea conditions at the time of sampling. APTIM geologists logged the vibracores by describing sedimentary properties by layer in terms of layer thickness, color, texture (grain size), composition and presence of clay, silt, gravel, or shells and other identifying features. Four sedimenttypes were observed within the five vibracores: silty sand (SM), well graded sand (SW), clay (CL), and clayey silt (ML-CL). The predominant sediment type that occurred within three of the five vibracores was a layer of black clay (munsell color value 5Y-2.5/1) ranging in depth between -7.2 ft NAVD88 to -16.6 ft NAVD88. Based the analysis of the sedimentary layers within the five vibracores it appears that sediments within the authorized channel corridor transition from a SM, sand and clayey silt to clay from Northeast to Southwest into Shallowbag Bay towards the Manteo Waterfront.

INTRODUCTION The purpose of the proposed project is to conduct a one-time maintenance dredging event within Ranges 1-4 of the federally authorized Manteo (Shallowbag) Bay navigation channel along with a connecting channel extending from Range 1 to the edge of the berth of the Elizabeth II docked along the western side of Festival Park (Figure 1). The authorized depth of the federal channel is -12 ft. MLLW. In order to characterize the material in the channel, APTIM collected and analyzed five vibracores throughout the proposed channel in which maintenance dredging will occur.

DCM-EC DATA COLLECTION Vibracore Sampling In order to obtain sediment samples from within the proposed dredging area, APTIM contracted with CATLIN Engineers and Scientists to collect vibracores. On July 30, 2019, five vibracores were collected under the direction of APTIM staff (Sub -Appendix 1). Figure 2 depicts the vibracore locations. Four of these vibracores (MVC-19-01, MVC-19-03, MVC-19-04, and MVC- 19-05) were collected within the footprint of the federally authorized channel. The remaining core, MVC-19-02, was collected outside of the authorized channel in order to characterize sediments located within the current deep -water channel as surveyed by the USACE in August 2019. To obtain these vibracores, CATLIN Engineers and Scientists used a system consisting of a generator and mechanical vibracore head connected via cable to a 3-inch lexan tube. The tube was vibrated to a pre -determined depth below the sediment -water interface or until refusal was experienced. Vibracore collection targeted the retrieval of undisturbed sediment samples from a depth of at least -14 ft. MLLW. Received MAP 112020 DCM-EC Figure 2. Vibracore collection in Shallowbag Bay aboard CATLIN vessel. APTIM geologists logged the vibracores by describing sedimentary properties by layer in terms of layer thickness, color, texture (grain size), composition and presence of clay, silt, gravel, or shells and other identifying features. Wet Munsell color was determined in accordance with American Society for Testing and Materials Standard Materials Designation D2488-09A for description and identification of soils (visual -manual procedure). The vibracores were digitally photographed against an 18% gray background. This is the standard reference value against which all camera light meters are calibrated. An 18% gray background is used to provide a known reference color. The vibracores were photographed in 2.0 ft. intervals. APTIM COASTAL PLANNING & ENGINEERING OF NORTH CAROLINA, INC. Sediment samples were extracted from the vibracores at irregular intervals based on distinct stratigraphic layers in the sediment sequence. The sediment samples collected from the vibracores during the logging process were analyzed to determine color and grain size distribution. During sieve analysis, any obvious uncharacteristically large fragments (such as whole shell or large shell fragments) were removed and the description (weight and size) of the material was noted. The wet, dry and washed Munsell colors were noted. Sieve analyses of the sediment samples were performed in accordance with the American Society for Testing and Materials (ASTM) Standard Methods Designation D 6913-17 for particle size analysis of soils. This method covers the quantitative determination of the distribution of sand size particles. For sediment finer than the No. 230 sieve (4.0 phi) the ASTM Standard Test Method, Designation D 1140-17 was followed. Carbonate analysis was not performed on the samples. Table 1 presents sieve sizes used for grain size analysis, weights retained on each sieve were recorded cumulatively.

Mae 112020 DCM-EC Munsell color values for the five 2019 APTIM vibracores noted in the vibracores logs describe the sediment as being dark gray to black, respectively. The 2019 APTIM vibracore data tables, logs, granularmetric reports, grain size curves/histograms and photographs are included in Sub - Appendices 2-5. Data Quality Data collection utilized industry standard survey systems and methodologies to collect geotechnical data. Vibracores were collected at varying distance throughout the targeted area to capture each portion of the channel. Despite the resolution of the geotechnical data, it is possible that interpolations between vibracores may result in unexpected material (rock, silty sand, clay, etc.) within the proposed channel. RESULTS Dredge Material Sediment Analysis Vibracores collected generally contained four predominant types of sediments. The first type of sediment consisted of sand (SW) that was light olive brown (2.5Y-5/6) in color with 0.95 percent fines. The second type of sediment consisted of silty sand (SM) that was dark olive gray in color with 30.51 percent fines. The third type consisted of clayey silt (ML-CL) with pockets of fine to silty sand, mottled black in color (5Y-2.5/1) with 69.42 percent fines. The fourth type consisted of clay (CL) was black in color (5Y-2.5/1) with 95.55 percent fines. One layer of organic peat (PT) was observed in MVC-19-05 between -12.5ft and -12.9ft NAVD. The most prevalent sediment type was clay that was sampled in three of the vibracores (MVC-19-03, MVC-19-04, and MVC- 19-05), All of the clay samples were black in color and very soft with trace amounts of organics and shell hash. All clay samples contained greater than 90 percent fines. Sub -Appendices 2 and 3 contain vibracore logs and photographs. The granularmetric reports and grain size curves/histograms for the samples collected from these vibracores are presented in Sub - Appendices 4 and 5, respectively. Based on recent surveys of the channels (August 2019) performed by the USACE, APTIM has calculated the volume of material within the limits of the authorized channel from Ranges 1-4 at depths ranging from -9 ft. MLLW to -12 ft. MLLW. The volume estimates do not include the volume of material to be removed immediately adjacent to the berth where the Elizabeth II is moored.

Sand, silty sand, and clayey silt were observed in two vibracores along the Northeast portion of Range 4 at the mouth of Shallowbag Bay at the intersection of the Roanoke Sound. Analyses of the samples collected from the APTIM 2019 vibracores indicate that sediments within the Shallowbag Bay authorized channel to Manteo become finer moving from the Northeast section of Range 4 to Southwest and into Ranges 1-3 along the Manteo waterfront and Roanoke Island Festival Park.

The project includes the following elements: • A channel 6 feet deep and 100 feet wide extending 1.6 miles from Manteo (Shallowbag) Bay through Roanoke Sound to that depth in Albemarle Sound (Referred to as Range 4A and 4B) • A channel 12 feet deep and 100 feet wide from a basin in front of the town of Manteo extendingl2.6 miles to and through Roanoke Sound to Old House Channel (Referred to as Ranges 1 through 17, including Range 17 Extension), including a side channel of the same dimensions 0.8 mile long to a basin at the town of Wanchese (Referred to as Ranges 14 A, B, and C) • A channel 12 feet deep and 100 feet wide extending 8 miles from Oregon Inlet via Old House Channel to the 12-foot contour in Pamlico Sound (Section from the Bridge to Old House Channel referred to as Oregon Inlet West Ranges 1 through 6; Old House Channel includes Ranges 1 and 2) • A channel 14 feet deep and 400 feet wide from the Oregon Inlet gorge across the ocean bar. Although the entire Manteo (Shallowbag) Bay project has been federally authorized, only portions have been maintained on a regular basis by the USACE. Over recent years, navigability has been compromised due to shoaling within the basin between the town of Manteo and Roanoke Island Festival Park and the channel extending through Shallowbag Bay into Roanoke Sound (Ranges 1 through 5). According to the USACE, this area has not been maintained by the USACE since the construction of the state-owned Wanchese Seafood Industrial Park in 1981 (T. Horton, personal communication, 2019). Since that time, the State of North Carolina continued to maintain this stretch of the federal project periodically. Specifically, the State has performed maintenance dredging within Ranges 1-5 of the Shallowbag Bay project six times since 1985. Five of these events were conducted with private contract dredges and one time with the State's Ferry Division plant. The amount of material removed during each of these six events ranged from 8,000 cy to 276,000 cy (Moffatt & Nichol, 2005). No maintenance dredging, however, has been performed within these channels since 2005 which has led to impediments to navigation over recent years. Received MAR 112020 ®CM -EC AManteo (Shallowbag) Bay Maintenance Dredging Project APTIM Recent bathymetric surveys in the channels proximate to Manteo were conducted by the USACE on January and February 2020. These surveys revealed the extent of compromised navigability due to the chronic shoaling. Specifically, sections of Range 2, Range 3, and Range 4 contain depths as shallow as -5' MLLW. As such, safe and reliable recreational boating opportunities have been limited within the area In addition, this continued shoaling has prevented the Elizabeth II, a representative 16' century sailing ship with an 8-foot draft, from navigating into Roanoke Sound from its home berth at Festival Park. Without the ability to sail to Manns Harbor where it can undergo repair and maintenance, the wooden vessel may become structurally unsound rendering it unable to fulfill its educational mission. In order for the ship to transit to Manns Harbor, it requires water depths greater than 8 feet. 2.0 Purpose and Need The stated purpose of the USACE's federally authorized Manteo (Shallowbag) Bay project is to provide a safe, reliable navigable channel from the Atlantic Ocean through Oregon Inlet to Roanoke Sound and connecting channels to Pamlico Sound. In the same spirit, Dare County is now seeking the necessary permits and clearances allowing them to perform maintenance dredging within Ranges 1-5 of the federally authorized project and a connector channel to the berth of the Elizabeth II to ensure safe, reliable navigation within those specific areas and to maintain the economic viability of the Town of Manteo and Festival Park. Without performing this maintenance dredging, the ability of the Elizabeth II and recreational boaters to navigate safely to and from Manteo and Festival Park to the Roanoke Sound will continue to be compromised. Furthermore, dependable navigation through these channels could jeopardize a potential loss of revenue due to loss of tourism spending for both the town of Manteo and Dare County. 3.0 Proposed Action Dare County's proposed action includes maintenance dredging within Ranges 1-5 of the federally authorized Manteo (Shallowbag) Bay project. Ranges 1-5, as depicted in Figure 1 includes the basin between the town docks at Manteo Festival Park just south of Doughs Creek and a channel that extends through Shallowbag Bay into Roanoke Sound In addition to the maintenance dredging within the federally authorized channel, the project will also include dredging a connector channel between Range 1 and the berth for the Elizabeth II (Figure 1 and Appendix A). In total, these areas span approximately 2.2 miles. The footprints within Ranges 1-5 will be maintained utilizing a clamshell bucket dredge dug to the same width (100') as the federally authorized channel. The depth, however, will be limited to -10' MLLW (the federal channel is authorized to -12') as will the channel connecting Range 1 to the berth of the Elizabeth II. Based on the January and February 2020 bathymetric surveys, approximately 90,000 cy of material could be dredged out of Ranges 1-5 at a depth to -10' MLLW. It is anticipated that approximately 1,500 additional cubic yards of material would be excavated from within the connector channel between Range 1 and the berth of the Elizabeth II. Dredging activities will be restricted by the general dredging moratoria and will not commence between April 1 and September 30.

Although the waters in proximity currently include depths greater than 4' (the estimated draft for a fully loaded barge), limited dredging be required within this area may be required to gain access to the offloading site. Dredging in proximity to the offloading site would be limited to a 75' wide channel down to -5' MLLW within a defined dredging corridor. The material will then be loaded directly into trucks and delivered to the dredge disposal area located within the grounds of the Dare County Regional Airport (Figure 2, Appendix A). Prior to disposal, the dredge disposal site will be cleared, graded, and improved as needed such that it will conform with DEMLR standards. Furthermore, all sediment control features associated with the disposal site will abide by those set forth in the conditions stated in DEMLR's Erosion Control Permit (permit pending). Site improvements at the dredge spoil disposal location will conform with DEMLR sediment control standards.

Congress defined Essential Fish Habitat as "those waters and substrate necessary to fish for spawning, breeding, feeding or growth to maturity". The MSFCMA requires that EFH be identified for all fish species federally managed by the Fishery Management Councils (FMC) and the National Marine Fisheries Service (NMFS). Eight FMC were established under the MSFCMA to manage living marine resources within federal waters and are required to describe and identify EFH designations in their respective regions. Each of these councils is responsible for developing Fishery Management Plans (FMP) to achieve specified management goals for fisheries. The FMP includes data, guidelines for harvest, analyses and management measures for a fishery. Each FMP must describe the affected fishery, analyze the condition of the fishery, and describe and identify relevant EFH. In close coordination, both the South Atlantic Fisheries Management Council (SAFMC) and the Mid -Atlantic Fisheries Management Council (MAFMC) manage marine fisheries in the federal waters off the North Carolina coast. Federal water limits off the North Carolina coast extend from 3 nautical miles to 200 nautical miles. In addition, the Atlantic States Marine Fisheries Commission (ASMFC) manages fisheries in the state waters of all 15 Atlantic coast states from Maine to Florida. The ASMFC manages fish stocks within the state waters of North Carolina from the coastline to three nautical miles offshore. The SAFMC is responsible for the conservation and management of fish stocks within the federal 200-mile limit of the Atlantic off the coasts of North Carolina, South Carolina, Georgia and east Florida to Key West. The seven states that comprise the MAFMC are New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia and North Carolina (North Carolina is also on the South Atlantic Council). The MAFMC also works with the ASMFC to manage summer flounder, scup, black sea bass, bluefish and spiny dogfish. The SAFMC broadly defines EFH habitats for all of its managed fisheries in a generic management plan amendment that contains life stage based EFH information for each of the federally managed species. The SAFMC currently manages eight fisheries that include coastal migratory pelagics, coral and live bottom habitat, dolphin and wahoo, golden crab, shrimp, snapper grouper, spiny lobster and Sargassum. Of these eight fisheries, only the snapper grouper complex contains species that are considered overfished. Both the recreational and commercial snapper grouper fisheries are highly regulated and progress continues to be made as more species are removed from the overfished list each year. The other fisheries are expected to continue into the future at productive sustainable levels (SAFMC, 2018). Received Malt 1 1 2020 DMEC AManteo (Shallowbag) Bay Maintenance Dredging Project APTIM The MAFMC is responsible for the conservation and management of fish stocks in the federal waters off the coasts of New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia and North Carolina. They have prepared multiple FMPs with amendments to identify EFH for each life stage (eggs, larvae, juvenile and adults) of its managed fisheries (Table 1). The MAFMC identifies several broad areas designated as EFH in estuarine and marine environments. The six FMPs developed by the council are the golden tilefish; summer flounder, scup, black sea bass; dogfish; surf clam and ocean quahog; Atlantic mackerel, squid, and butterfish; and bluefish (MAFMC, 2019).

Organizations responsible for Fishery Management Plans include: SAFMC (South Atlantic Fishery Management Council); FMC (Mid -Atlantic Fishery Management Council; NMFS = National Marine Fisheries Service) Received MAR 112029 DWEC A APTIM Manteo (Shallowbag) Bay Maintenance Dredging Project NMFS has also prepared multiple FMPs with amendments to identify EFH within its authority. Four fisheries (billfish, swordfish, tuna and sharks) are managed under the FMPs of NMFS and are classified as Highly Migratory Species (HMS). NMFS geographically defines EFH for each HMS along the Atlantic coast. The defined EFH areas are species -specific and include shallow coastal waters, offshore waters inside the exclusive economic zone (EEZ), offshore waters outside the EEZ and inshore waters along the Atlantic coast (NMFS, 2010). The North Carolina Marine Fisheries Commission (NCMFC) manages commercially and recreationally significant species of fisheries found in state marine or estuarine environments. The NCMFC designates Primary Nursery Areas (PNA) that are included as EFH by the SAFMC. The waters of Shallowbag Bay are a major component of Dare County's estuarine system. This highly productive biological system provides habitat for estuarine dependent species which must spend all or some part of their life cycle within the estuarine waters to mature and reproduce. Shallowbag bay has been designated as a nursery ground for many sport and commercial fish species found in North Carolina's waters due primarily to the intermixing of freshwater and brackish water in the bay (Wild-Ramsing, 1983). 4.1.2 Habitats Designated as EFH Aside from the life -stage based EFH defined for managed fish species, the SAFMC and MAFMC have designated eight habitats as EFH, listed in Table 2. Of those habitats listed, only estuarine water column, seagrass, and oyster reef and shell banks are found in proximity of the project area. Brief descriptions and effects determinations for all EFH categories near the proposed Project Areas are continued below. Table 2. Estuarine Essential Fish Habitat identified in FMP Amendments of the South Atlantic and Mid -Atlantic FMC's (NMFS. 2010a). SAFMC MAFMC Estuarine Areas Estuarine Areas Estuarine Emergent Wetlands Seagrass Estuarine Scrub/Shrub Mangroves Creeks Oyster Reefs and Shell Banks Mud Bottom Intertidal Flats Estuarine Water Column Palustrine Emergent and Forested Wetlands Aquatic Beds Estuarine Water Column Estuarine Water Column The SAFMC and MAFMC designate estuarine and marine water columns as EFH. The SAFMC defines the estuarine water column as the medium of transport for nutrients and migrating organisms between river systems and the open ocean (SAFMC, 1998). The estuarine ter column 8 Keceived MAR 112029 DCM-EC As Manteo (Shallowbag) Bay Maintenance Dredging Project APTIM is organized into salinity categories ranging from 0 ppt to > 30 ppt according to the method of classification utilized. The entirety of the aquatic portion of the project area considered estuarine water column EFH. The North Carolina Division of Water Quality (NCDWQ) classifies the Shallowbag Bay and Roanoke Sound as SC (tidal saltwater). During dredging, the estuarine water column may experience a temporary elevation of turbidity levels in proximity to the dredge. When sediment re -suspension occurs, larger particles will likely settle out; however, the finer sediments will remain suspended for longer periods in turbulent water (Adriaanse and Coosen, 1991). Suspended particles may interfere with the biological functions of some organisms such as feeding, respiration, reproduction and potentially cause predator avoidance. High turbidity and silt loads can have detrimental impacts to filter feeding organisms associated with nearshore benthic communities including amphipods, isopods, decapods, polychaetes, mollusks and others. The conditions of diminished light penetration within the water column can detrimentally affect the photosynthetic activity of phytoplankton, the primary producers of energy production. The re -suspended material in proximity to the dredge is expected to settle relatively rapidly due to the typical relatively calm conditions within Shallowbag Bay. Compared to marine environments, these relatively calm conditions will allow for rapid settling of suspended particles and, therefore, the dredging activity should have no appreciable effects on the dissolved oxygen, pH or temperature. Accordingly, it is anticipated the proposed project will have only minor temporary impacts to the estuarine water column within the proposed dredging locations. Seagrass Seagrass, or submerged aquatic vegetation (SAV), is generally defined as submerged lands that are vegetated with one or more species of submerged aquatic vegetation, or have been vegetated by one or more species of submerged aquatic vegetation within the past 10 annual growing seasons. The average physical requirements of water depth (six feet or less), average light availability (secchi depth of one foot or more) and limited wave exposure that characterize the environment suitable for growth of SAV are also required to meet the general definition. (NC Marine Fisheries Commission (NCMFC) (15A North Carolina Administrative Code (NCAC) 03I.0101(4)(i)). In North Carolina, the most common species of SAV is eelgrass (Zostera marina), shoalgrass (Halodule wrightii) and widgeon grass (Ruppia maritime). These vegetation beds occur in both subtidal and intertidal zones and may occur in isolated patches or cover extensive areas (Deaton, 2010). SAV is designated EFH for the snapper/grouper complex, red drum and penaeid shrimp by the SAFMC (NMFS, 2010). Blue crabs, which are managed by the NCDMF, also utilize seagrass habitat during various life stages. In terms of their value as EFH, seagrass bed ecosystems are utilized by larval and juvenile fishes for foraging, spawning and escape from predation. Commercial and sport fishes in their larval and juvenile stages, such as gag grouper (Mycteroperca microlepsis), gray snapper (Lutjanus griseus), bluefish (Pomatomus saltatrix), flounder species (Paralichthys sp.), fish of the Clupeidae family and others are found in seagrass beds in the early spring and summer (ASMFC, 2016). Bay scallops (Argopecten irradians concentricus) are also typically found in SAV habitat. Because of its use for foraging, spawning and shelter, SAV is 9 Received Nee 1 1 2020 DCM-EC AMan teo (Shallowbag) Bay Maintenance Dredging Project APTIM designated as HAPC. The red drum (Sciaenops ocellatus) is one species that SAV serves as a HAPC. The Carolinas are in a transitional area that represents the southernmost extension for some cold - adapted species and the northernmost extension of warm -adapted species. In North Carolina, the dominant seagrass, eelgrass (Zostera marina), grows at the southernmost extent of its range, while shoal grass (Halodule wrightii) is at its northernmost extent. SAV is an important indicator of environmental health because of its sensitivity to aquatic stressors. Factors affecting SAV distribution include the hydrodynamic characteristics of water velocity, depth, waves and the water's ability to transport sediments. Boating operations cause direct impacts to SAV as a result of increased wave action, propeller damages, and by reduced light due to the suspending of bottom sediments and manmade overhangs and structures (i.e. piers). Indirectly, the construction and maintenance of channels by dredging may suspend sediments leading to decreased light transmissivity and burial of the vegetation. Consequently, the mapping of SAV allows for their avoidance during the planning and design of new vessel channels and marine basins. Environmental scientists from Quible & Associates conducted a SAV survey in and around the areas of Shallowbag Bay and the Roanoke Sound in 2004 (Quible, 2005). On October 20, 2004, a total of thirteen random sampling locations were chosen within areas in proximity to Shallowbag Bay. In addition, three raking stations were chosen in shallow water areas. At each sampling location, latitude and longitude coordinates were recorded along with depth to bottom measurements, which were obtained with a PVC measuring rod calibrated in feet. Substrate samples were collected using a petite PONARTM substrate grab sampling device. The majority of the samples collected consisted of black organic rich muds. Raking was conducted in shallow areas (less than 6 feet). Raking was not deemed necessary in deeper areas where sunlight does not penetrate to the substrate. No SAVs or evidence of SAVs were observed in any of the 13 samples collected or in any of the raked areas. In addition, during the 31 plus shallow water dives performed during an associated vibracore sampling effort (October 28-30, 2004) no SAVs were observed to occur. Based on field observations, Quible determined it is unlikely that any SAV grows in the types of substrates noted or at the depths within the areas investigated (Quible, 2005). In addition to the investigation of SAV occurrences conducted by Quible, as described above, SAV occurrences within coastal areas in North Carolina have been delineated by NWS using visual interpretation of SAV areas using high resolution aerial photography. The most recent visual interpretation for the area surrounding Shallowbag Bay was conducted using 2006-2008 aerial imagery. Figure 3 depicts the extent of the SAV occurrences to the north of the footprint of the proposed channel maintenance project. Received 10 MAP 112020 DCM-EC Figure 3.

Figure 4 depicts the distribution of the various habitats within the project area that contain shellfish resources based on data from the NCDMF Shellfish Mapping Program. The blue polygons in proximity to the federally authorized dredging footprint is designated as "subtidal firm unvegetated shell' habitat. No other shellfish habitat has been identified within the project area. Because the known shellfish resources lie outside of the proposed dredging footprint, no direct impacts are anticipated. The temporary increase in turbidity and sedimentation could impact oyster reefs, however, the dredging activity will be limited by the environmental dredge window (April 1 through September 30). Therefore, dredging will not occur during while oysters and shellfish are most biologically active. As such, these resources are not anticipated to be directly or indirectly impacted by this proposed project. x. fi v i 1AI6 WtWwCmPfwovatl Y r-�ii�.s-�m.a sa Z FIMums »N�MIILOnAW I puamb'n+twcE ^ fmwnlpev»mi3i Il 11NniWi04YaNwnFN NNYala.�b�s LNYMkt019MN11Rl(MNMm 1'�.elMwblle IfR]WITp Epf.

Estuarine Emergent Wetlands The SAFMC defines estuarine emergent wetlands as tidal wetlands in low -wave energy environments, where the salinity is greater than 0.5 parts per thousand (ppt) and total vegetation cover is greater than 80 percent (SAFMC, 1998). Salt and brackish marshes are types of wetlands occurring in shallow water lagoons located behind sand barrier islands in North Carolina. Estuarine marsh sediments are usually muddy with high organic matter content. Some of the most productive and valuable wetlands are coastal marshes (SAFMC, 1998). These tidal wetlands are 12 Received mae 112020 DCM-EC Monteo (Shallowbag) Bay Maintenance Dredging Project APTIM F S +jj k •S..'� ',k. r NN.c J,9gp11: miemswa.e •:.+wraa.�-c�..6n..,, m:q AiMwp.Nµ�uWC WB.t.lbn is'�nvoeman�e.n,a bNLocu NGunw Ltinrswwa ,: � ]Ebriie MGi^pwhG.

Because the known SAV areas lie outside of the proposed dredging footprint within Ranges 1-5, the connector channel into the berth for the Elizabeth H, or in proximity to the offloading site for dredged material, no direct impacts are anticipated. The temporary increase in turbidity could reduce light penetration and therefore impact SAV growth, however, the dredging activity will be limited by the environmental dredge window (April 1 through September 30). Therefore, dredging will not occur during the active SAV growing season. As such, SAV resources are not anticipated to be directly impacted by this proposed project. Oyster Reefs and Shell Banks The SAFMC defines this habitat as the natural structures found between (intertidal) and beneath (subtidal) tide lines that are composed of oyster shell, live oysters and other organisms that are discrete, contiguous and clearly distinguishable from scattered oysters in marshes and mudflats and from wave -formed shell windows (SAFMC, 1998). Common terms used to describe shell bottom habitats in North Carolina are "oyster beds," "oyster rocks," "oyster reefs," ``oyster bars," and "shell hash." Shell hash is a mixture of sand or mud with gravel and/or unconsolidated broken shell (clam, oyster, scallop and/or other shellfish). Extensive intertidal oyster rocks occur in North Carolina's southern estuaries, where the lunar tidal ranges are higher. The SAFMC has designated oyster reefs as EFH for red drum (NMFS, 2010). The North Carolina Division of Marine Fisheries differentiates potential shellfish habitat by strata types. Designated strata types are classified based on characteristics of the habitat including subtidal or intertidal setting; soft, firm or hard s ate- . 11 uMved N"0 1 12020 DMED f t �b a H i d We Legend: t—xlBNtlaw�bbwrrr wm�am � swx,iiem xorwpewm snm � u���mo�w+eT�acmm mn 1.

Species such as salt marsh cordgrasses (Spartina alternii fora and S. patens), glasswort (Salicornia sp.), salt grass (Distichlis spicata) needlerush (Juncus roemerianus), and sea lavender (Limonium carolinanum) are commonly found within these wetlands. These habitats are important for fish and invertebrate spawning and juvenile development (Street et al., 2005). Coastal marsh environments are located in the areas surrounding Shallowbag Bay (Figure 5). The dredging footprint or barge landing area do not contain any wetland habitat. An erosion and sediment control plan has been developed for this project and has been submitted to the Division of Energy, Mineral and Land Resources as part of their permitting application.

HAPC may include high value intertidal and estuarine habitats, offshore areas of high habitat value or vertical relief and habitats used for migration, spawning and rearing of fish and shellfish (NMFS, 2004). Areas identified as HAPC by the NMFS and the FMCs in the South Atlantic and North Carolina are presented in Table 3 below (NMFS, 2010).

Primary Nursery Areas (PNAs) encompass approximately 80,000 acres throughout North Carolina. PNAs are typically shallow with soft muddy bottoms and surrounded by marshes and wetlands. They are found in the upper portions of bays and creeks, where the low salinity and abundance of food is ideal for young fish and shellfish. To protect juveniles, many commercial fishing activities are prohibited in these waters. Secondary Nursery Areas (SNAs) are located in the lower portion of bays and creeks. As juvenile fish and shellfish develop, primarily blue crabs and shrimp, they move into these waters. Trawling is prohibited in SNAs. Special SNAs are found adjacent to SNAs, but closer to the open waters of sounds and the ocean. These waters are closed for a majority of the year when juvenile species are abundant (Deaton et al., 2010). According to NC Division of Marine Fisheries (DMF), the project area includes PNA, Special Secondary Nursery Areas (SSNA) and Secondary Nursery Areas (SNA). The areas of PNA include Range 1 and the connector channel between Range 1 and the berth for the Elizabeth II at 14 Received u t4 112C21 DCM-EC A` Manteo (Shallowbag) Bay Maintenance Dredging Project APTIM Festival Park. The western portion of Shallowbag Bay, also known as "Inner Shallowbag Bay" has been designated as a permanent SNA which includes the area in proximity to the offloading area that may be dredged to -5' MLLW should the existing depths preclude navigation for the barge during construction. The eastern portion of Shallowbag Bay ("Outer Shallowbag Bay") has been designated as an SSNA (Figure 6). Figure 6. Primary and secondary nursery areas in proximity to the project area. Dredging has occurred multiple times within Range 1-5 in the past. The area within Range 1 is designated as PNA While Ranges 2-4 are considered SSNA and SNA. As stated in Section 1, the USACE had been responsible for the maintenance dredging within Ranges 1-5 prior to 1981. Since that time, the State of North Carolina continued to maintain this stretch of the federal project periodically. Specifically, the State has performed maintenance dredging within Ranges 1-4 of the Shallowbag Bay project six times since 1985. Five of these events were conducted with private contract dredges and one time with the State's Ferry Division plant. The amount of material removed during each of these six events ranged from 8,000 cy to 276,000 cy (Moffatt & Nichol, 2005). Dredging has also previously been performed within the connector channel between Range 1 and the berth for the Elizabeth II which is designated as PNA. The captain of the Elizabeth H, Robbie Putnum, has stated that the area was dredged sometime between 1982 and 1984 corresponding to the time period when the ship was first brought to the site. Captain Putnam also recalled a dredging 15 Received M14 11 1C27 DMEC zl CL^� S.

A CAMA Major permit (#83-82), issued on June 15, 1983 issued to the NC Department of Transportation authorized this dredging work. The same dredging footprint in proximity to the berth of the Elizabeth II, as depicted in Permit #83-82, is included in this proposed action. SSNA and SNA typically have high abundances of post -larval and sub -adult fishes and crustaceans and while PNA provides habitat for high abundances of larval and post -larval individuals. In an attempt to minimize project -related impacts to these resources, this project will abide by the April 1 to September 30 fisheries moratorium. 4.4 Significant Natural Heritage Areas The North Carolina Natural Heritage Program (NCNHP) serves as an information clearinghouse in support of conservation of the rarest and most outstanding elements of natural diversity in the State. These elements of natural diversity include plants and animals that are so rare or natural communities that are so significant that they merit special consideration in land -use decisions. A total of 34 natural areas are recognized in Dare County. Of these, two are in proximity to Shallowbag Bay and Manteo including the Fort Raleigh Maritime Forest, the Mother Vineyard Natural Area, West Roanoke Island Marshes, and the Roanoke Island Juncus Marshes. Fort Raleigh Maritime Forest The Fort Raleigh Maritime Forest is a stunted forest of live oaks, maples, and pines that is unique to the harsh conditions of the North Carolina coast. This site is home to a reconstruction of the early English settlement that creates a living history through buildings and a maritime landscape. It also houses the outdoor theater performances of the Lost Colony. This area is designated as the Fort Raleigh National Historic Site and is managed under the National Park Service. It is located on the north end of Roanoke Island, outside of Manteo's planning jurisdiction (Community Development by Design, 2007). Mother Vineyard Natural Area Mother Vineyard Natural Area, a SNHA of local significance, is State-owned land managed by the North Carolina Wildlife Resource Commission. It is located just north of Manteo, outside the town boundaries. This area is also called the Roanoke Island Festival Park, DNP, although it is adjacent to, not overlapping with, the historic site of Festival Park and Elizabeth 11(Community Development by Design, 2007). Due to the proximity of these locations to the proposed project area, neither of these natural areas will be impacted by the proposed project. 4.5 Threatened and Endangered Species Received 16 u�o 112C?7 D M-EC A® Manteo (Shollowbog) Bay Maintenance Dredging Project APTIM The threatened and endangered (T&E) species under consideration were identified through consultation with the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (UFWS). Through this consultation, it was determined that the only species that could be present in the project area based upon their historic geographic range was the shormose sturgeon, Atlantic sturgeon, and the West Indian Manatee. The actual occurrence of a species in the project area would depend upon the availability of suitable habitat, the seasonality of occurrence, migratory habits and other factors. 4.5.1 Shortnose Sturgeon The shortnose sturgeon (Acipenser brevirostrum) was listed as endangered on March 11, 1967 under the Endangered Species Preservation Act of 1966 (a predecessor to the Endangered Species Act of 1973). NMFS later assumed jurisdiction for shortnose sturgeon under a 1974 government reorganization plan (38 FR 41370). The shortnose sturgeon is the smallest of the three sturgeon species that are found in eastern North America, rarely exceeding a length of 4.7 ft and a weight of 50.7 pounds (NMFS, 2019a). Shortnose sturgeons are bottom feeders, typically feeding on crustaceans, insect larvae, worms, mollusks and some plants (NMFS, 1998). They appear to feed either in freshwater riverine habitats or near the freshwater/saltwater interface. This species is anadromous, primarily utilizing riverine and estuarine habitats, migrating between freshwater and mesohaline river reaches. Spawning occurs in upper, freshwater areas, typically in January and February while feeding and overwintering activities may occur in both fresh and saline habitats. Aside from seasonal migrations to estuarine waters, this species rarely occurs in the marine environment (NMFS, 1998; Keiffer and Kynard, 1993). Historically, shormose sturgeon were found in the coastal rivers along the East Coast of North America —from the Saint John River in New Brunswick, Canada, to the St. Johns River in Florida, and perhaps as far south as the Indian River in Florida. Currently, shortnose sturgeon can be found in 41 bays and rivers along the East Coast, but their distribution across this range is broken up, with a large gap of about 250 miles separating the northern and mid -Atlantic metapopulations from the southern metapopulation. Because of this distance between the shortnose sturgeon in mid-Atlantic/northern metapopulations and the southern metapopulation, adults from the two areas may never meet to breed. In the southern metapopulation, shormose sturgeon are currently found in the Great Pee Dee, Waccamaw, Edisto, Cooper, Santee, Altamaha, Ogeechee, and Savannah rivers. They may also be found in the Black, Sampit, Ashley, Roanoke, and Cape Fear rivers, as well as Albemarle Sound and Pamlico Sound. Shortnose sturgeon used to be considered extinct in the Satilla, St. Marys, and the St. Johns rivers, but were recently found again in both the Satilla and St. Marys rivers. There are accounts of shortnose sturgeons occurring in the Atlantic Ocean offshore of North Carolina (Holland and Yelverton, 1973; Dadswell et al., 1984), however, these records are not well substantiated and there is speculation as to whether they were misidentified juvenile Atlantic sturgeon (Shortnose Sturgeon Status Review Team, 2010). Those shormose sturge 17 `deceived A" 9 112029 ®CM -EC A® Manteo (Shallowboy) Bay Maintenance Dredging Project APTIM captured in the ocean are usually taken close to shore, in low salinity environments; there are no records of shortnose sturgeon in the NMFS database for the northeast offshore bottom trawl survey (NMFS, 1998). The historical presence of sturgeon in Albemarle Sound and tributaries was reviewed by Armstrong and Hightower (2002). Most historic commercial sturgeon landings records were from Albemarle Sound, but given that sturgeon species were not differentiated (Moser et al. 1998), it cannot be determined if they were shormose or Atlantic sturgeon. There are no historic reports of shortnose sturgeon from the open sound. There are only two documented records of shortnose sturgeon in the Albemarle Sound watershed, both from within tributaries of Albemarle Sound: 1) a juvenile specimen was collected in 1881 (Vladykov and Greeley, 1963) from Salmon Creek an adult was collected in 1998 (Armstrong, 1999; Oakley and Hightower, 2007) from western Batchelor Bay near the mouth of the Roanoke River. No shortnose sturgeon have been definitively documented in Albemarle Sound or its tributaries since 1998. When Moser et al. (1998) surveyed commercial fishermen to determine whether they had captured shortnose sturgeon in NC waters, shortnose sturgeon were reported as occasional captures in pound and gill nets in Bachelor's Bay at the mouth of the Roanoke River, and in gill nets set in the North River Due to the paucity of shortnose sturgeon in Shallowbag Bay and the fact that the project is not located within shortnose sturgeon critical habitat, no impacts to the species is anticipated as a results of the proposed action. 4.5.2 Atlantic Sturgeon In 2009, the Natural Resources Defense Council (NRDC) petitioned NMFS to list the Atlantic sturgeon (Acipenser oxyrinchus) under the Endangered Species Act of 1973 (ESA). As a result of the petition, four Distinct Population Segments were listed as endangered on February 6, 2012, including the South Atlantic DPS, the Carolina DPS, the Chesapeake Bay DPS and the New York Bight DPS. The project area falls within the range of the Carolina DPS. Atlantic sturgeon are similar in appearance to shortnose sturgeon (Acipenser brevirostrum), but can be distinguished by their larger size, smaller mouth, different snout shape and scutes (NMFS, 2019b). The Atlantic sturgeon is a long-lived, estuarine dependent, anadromous fish. They are benthic feeders and typically forage on invertebrates including crustaceans, worms and mollusks. Atlantic sturgeon can grow to approximately 14 feet long and can weigh up to 800 pounds (NMFS, 2019b). They are bluish -black or olive brown dorsally (on their back) with paler sides and a white belly. Adults range from St. Croix, ME south to the St. Johns River in Florida (NMFS, 2019b). These fish undergo seasonal migrations to and from freshwater, but spend much of their adult life in the marine environment for growth (Stein et al., 2004; Atlantic Sturgeon Status Review Team, 2007). Atlantic sturgeons are found offshore primarily during the fall to spring months of approximately October to March. However, different life stages will utilize the marine environment during the summer as well. Although Atlantic sturgeons spawn repeatedly, they do not necessarily spawn every year (Smith and Clugston, 1997). During non -spawning years, adults may utilize marine 18 Received Al"' 1 12C29 DCM-EC A` Manteo (Shallowbag) Bay Maintenance Dredging Project APTIM waters year-round (Bain, 1997). Spawning adults migrate upriver in spring, beginning in February to March in the south, April to May in the mid -Atlantic, and May to June in Canadian waters. In some areas, a small spawning migration may also occur in the fall. Spawning occurs in flowing water between the salt front and fall line of large rivers. Atlantic sturgeon spawning intervals range from one to five years for males and two to five years for females (NMFS, 2019b). Following spawning, males may remain in the river or lower estuary until the fall while females typically exit the rivers within 4 to 6 weeks (NMFS, 2019b). Juveniles move downstream and inhabit brackish waters for a few months and when they reach a size of about 30 to 36 inches, they move into nearshore coastal waters (Smith, 1985). Tagging data indicates that these immature Atlantic sturgeons travel widely once they emigrate from their natal (birth) rivers. Sturgeons are distributed within areas that provide foraging opportunity. The narrow depth ranges and substrate types preferred by sturgeon correspond with bottom features that likely support depth -specific concentrations of prey (Stein et al., 2004; Kynard et al., 2000). Analysis of commercial fishery by -catch data suggests that, along the northeastern U.S., migratory sub -adults and adults show preference for shallow (33-164 ft) coastal areas dominated by gravel and sand substrate (Stein et al., 2004). Within the mid -Atlantic Bight (including coastal North Carolina), sturgeon may prefer even shallower depths (82 ft or less). Coastal features, such as inlets and mouths of bays, support high concentrations of Atlantic sturgeon presumably due to the physical and biological features produced by outflow plumes (Stein et al., 2004). The Atlantic sturgeon was historically abundant within Albemarle Sound and the Roanoke River in North Carolina, but declined dramatically in the late 1800's in response to intensive fishing. Recent evidence suggests that the population may be recovering following a statewide prohibition on harvest in 1991. A recruitment index generally increased from 1992 through 2001 (Armstrong and Hightower, 2002). Bycatch mortality because of commercial gill -netting in Albemarle Sound could affect recovery. Telemetry and netting data indicate thatjuvenile Atlantic sturgeon in the sound are most abundant in shallow nearshore areas where commercial gill -netting is concentrated (Armstrong and Hightower, 2002). The bycatch data for the years of 2004-2006, 2008, and 2013-2016 show that 57 Atlantic sturgeon were caught in the Albemarle Sound (Hoos et al., 2019). These observations, however, were from the western portion of the Sound without any observations in proximity to the eastern portion of Albemarle Sound or Shallowbag Bay. Encounters with the dredge in or near the dredge site would be most likely to occur in the winter and spring, after spawning and the migrations to feeding areas in downstream estuarine waters (NMFS, 1999). These individuals will be larger than 45 cm in length, which is too large to become entrained by the clamshell bucket dredge. Furthermore, because of their mobility, it is presumed these individuals would be capable of avoiding and out -maneuvering the slow -moving dredges, greatly reducing any chances of collision or interaction. For these reasons, it is determined that the potential impacts to shortnose and Atlantic sturgeon are insignificant and extremely unlikely, and therefore the project activities may affect, but are not likely to, adversely affect shormose sturgeon. 19 Received p,° 11 K20 D M-EC A APTIM 4. S. 3 West Indian Manatee Manteo (Shallowbag) Bay Maintenance Dredging Project The West Indian manatee is listed as a federally protected species under the Endangered Species Act of 1973 (ESA) and the Marine Mammal Protection Act of 1972 (MMPA). An adult manatee is, on average, 10 ft. (3 m) long, weighs approximately 2,200 lbs. and is typically referred to as the "sea cow." The coloring of the manatee is grayish brown, which contributes to the difficulty in detecting manatees in silt -laden waters. This mammal can be found in shallow waters (5-20 ft [1.5- 6.1 m]) of varying salinity levels including coastal bays, lagoons, estuaries and inland river systems. Manatees primarily feed on aquatic vegetation, but can be found feeding on fish, consuming between four and nine percent of their body weight in a single day (USFWS, 2019). Sheltered areas such as bays, sounds, coves and canals are important areas for resting, feeding and reproductive activities (Humphrey, 1992). The West Indian manatee occupies the coastal, estuarine and some riverine habitats along the western Atlantic Ocean from Virginia to the Florida Keys, in the Gulf of Mexico, the Caribbean Islands, Mexico, Central America and northern South America (Garcia -Rodriguez et al., 1998; USFWS, 2014). The West Indian manatee (Trichechus manatus) includes two subspecies, the Florida manatee (T. in. latirosals) and the Antillean manatee (T. M. manatus). Within U.S. waters, the Florida manatee can be found throughout the southeastern U.S., including North Carolina, while the Antillean manatee is found in Puerto Rico and the Virgin Islands (Lefebvre et aL, 2001). As the Antillean manatee does not occur within the southeastern U.S., this biological assessment will only evaluate the Florida manatee population. Occurrence throughout the southeastern U.S. changes seasonally, as the manatees seek out warmer water temperatures. During the winter months (October through April), the entire U. S. population typically moves to the waters surrounding Florida (Humphrey, 1992). The greatest threat and cause of mortality for manatees is boat collisions. Other dangers to the species include entanglement in fishing lines, entrapment and entanglement in locks, dams and culverts, loss of warm -water refuge areas, and exposure to cold. Long-term and cumulative impacts are associated with a loss of aquatic vegetated habitat and blocking of estuarine and riverine systems (Runge et aL, 2007). Sightings and stranding data suggest the Florida manatee occurs within inland and coastal waters of North Carolina, and they have been sighted most frequently from June through October when water temperatures are warmest (above 710F [22°C]) (USFWS, 2003). Manatees may also overwinter in North Carolina where the discharge from power plants supports the warm water temperatures (USFWS, 2009). The USFWS has reported manatee sightings in the last 20 years in the counties of Beaufort, Bertie, Brunswick, Camden, Carteret, Chowan, Craven, Currituck, Dare, Hyde, New Hanover, Onslow, Pamlico, Pasquotank, Pender, Perquimans, Pitt, Tyrrell and Washington. Cummings et al. (2014) documented 99 manatee sightings in North Carolina from 1991 to 2012, with 30 manatee sightings occurring in 2012 (note: the authors speculate that the large number of sightings in 2012 may be due to increased public awareness). Manatees arrived in North Carolina in April, and sightings were most common from June to October, when water 20 Received �1 kn 112020 DMEC A® Man teo (Shallowbag) Boy Maintenance Dredging Project APTIM temperatures were above 20°C (68°F). Sightings declined with water temperature in November, and manatees appeared to be absent from the region from December through February (Cummings et al., 2014). Within northeastern North Carolina, sightings increased since 2011, which may be due to greater awareness and improved survey efforts (Cummings et al., 2014). The greatest number of manatee sightings occurred within the Intracoastal Waterway, sounds and bays, and rivers and creeks. Manatees were least commonly sighted in the open ocean and around marinas. The sightings and strandings reported within North Carolina from 1999 through 2012 show very few documented occurrences within the large sounds in northern North Carolina, including the Pamlico Sound. There was one manatee sighting and one stranding documented in the vicinity of Hatteras Inlet from 1991 through 2012. One of the major threats to the West Indian manatee in collisions with watercraft, which can result in serious injury or mortality. Manatees are present seasonally in North Carolina and are most commonly sighted in the Intercoastal Waterway or sounds and bays. There is also substantial submerged aquatic vegetation (SAV), a primary food source for manatees, within the Roanoke Sound and Shallowbag Bay. The number of manatees potentially occurring in the Project Area is not known with certainty but is presumed to be low with the greatest likelihood of occurrence during the warmer months, in particular June through October. It is therefore considered possible, but unlikely, that a manatee may be present in the Shallowbag Bay during the warmer months, particularly June through October. Because this project will abide by the April I to September 30 fisheries moratorium, manatee and vessel interactions will be significantly minimized. During construction or dredging, the contractor will adhere to the "Guidelines for Avoiding Impacts to the West Indian Manatee" (See Appendix F) developed by the USFWS for general construction activities in waters used by the species. Fulltime NMFS-certified protected species observers will be present on the barge to alert the dredge operator of any marine mammals, including manatees, in the area. In the event a manatee is spotted, the barge's captain will make proper maneuvers to avoid collisions or injury to the marine mammals. 4.6 Water Quality The waters of Shallowbag Bay and its surrounding waters are classified as SC by the North Carolina Department of Environmental Quality, Division of Water Resources (DWR) indicating that the waters are protected for fishing, secondary recreation, and any other usage except primary recreation or shellfishing for market purposes (Figure 7). Although the State does not currently maintain any water quality monitoring sites within the project area, the waters within the project area, including Doughs Creek and Shallowbag Bay, are all closed for the harvesting of shellfish as per the North Carolina Division of Marine Fisheries (DMF). The primary reason for the shellfish closure around Shallowbag Bay is to serve as a buffer around the Manteo Wastewater Treatment Plant (WWTP) discharge which is located approximately 3,400 feet offshore in Shallowbag Bay. The WWTP has a history of exceeding its permit limits for fecal coliform, petroleum, and ammonia levels in its effluent. In 2005 and 2006, there were two Notice 21 Received MAR 112021 DCM-EC At Manteo (Shallowbag) Bay Maintenance Dredging Project APTIM of Violations issued against MWWTP and 9 Permit Enforcement penalties issued against the plant. Although no water quality data is actively being collected by the State to determine the current conditions, the shellfish closure will remain unless the discharge is removed (A. Haines, 2019, personal communication). 22 Received mAQ 1 1 2021 ®CM -EC AMonteo (Shallowbag) Bay Maintenance Dredging Project APTIM Figure 7. Shellfish harvesting closures in Shallowbag Bay, Scarboro Creek, Doughs Creek, and surrounding areas. Bucket and barge dredging operations such as what is being proposed for this project has the potential to impact to water quality due to increases of turbidity and the resuspension of 23 Received MA2 1 1 2020 DCM-EC A Manteo (Sholowbog) Bay Maintenance Dredging Project APTIM contaminated sediments (Montgomery, 1984). Sediment resuspension characteristics of selected dredges and operational techniques have been evaluated by Raymond (1983). The bucket dredge consists of various types of buckets operated from a crane or derrick mounted on a barge or on land. The resuspension of sediments during bucket dredging is caused primarily by the impact, penetration, and withdrawal of the bucket from the bottom sediments. Secondary causes are loss of material from the bucket as it is pulled through the water spillage of turbid water from the top and through the jaws of the bucket as it breaks the surface, and inadvertent spillage while dumping. In addition, sediment resuspension may also result from other activities directly associated with dredging (e.g. spillage, prop wash from tugs and attendant vessels, spuds, dredge movement, and anchoring systems). Limited field measurements on sediment resuspension caused by bucket dredges showed that the maximum suspended sediment concentration in the immediate vicinity of the dredging operation was less than 500 mg/1 and decreased rapidly with distance from the operation due to settling and mixing effects (Raymond, 1983). The major source of turbidity in the lower water column is sediment resuspended at the impact point of the clamshell. The resuspension of sediments during dredging operations pose a variety of water quality and ecological concerns. The visible contiguous turbidity plume in the immediate vicinity of the dredging operation could influence the behavior of fish and other receptors sufficiently mobile to avoid the plume and potentially impact the health of less mobile aquatic vertebrates and invertebrates. Resettling of suspended particulates could also impact bottom -dwelling organisms. When sediment resuspension occurs as a result of dredging activity, larger particles rapidly settle out; however, the finer sediments will remain suspended for longer periods, or even indefinitely in turbulent water (Adriaanse and Coosen, 1991). Suspended particles may interfere with the biological functions of some organisms such as feeding, respiration, reproduction and potentially cause predator avoidance. High turbidity and silt loads can have detrimental impacts to filter feeding organisms associated with nearshore benthic communities including amphipods, isopods, decapods, polychaetes, mollusks and others. The conditions of diminished light penetration can detrimentally affect the photosynthetic activity of phytoplankton, the primary producers of energy production. As stated above, the Manteo Waste Water Treatment Plant discharges it's treated effluent in Shallowbag Bay and has had a history of regulatory issues. As such, the sediments within Shallowbag Bay may contain contaminants which, upon disturbance during dredging activities, may become resuspended in the water column. The particulate -associated contaminants can repartition, thereby increasing dissolved contaminant concentrations in the water column which could be detrimental as plants and animals residing in proximity of the project area could uptake contaminants following disposal operations (Bridges et al., 2008). Investigations by Fulk, Gruber, and Wullschleger (1975) showed that, for suspended solids concentrations of less than 100 g/l, the amount of pesticides and PCBs that are dissolved or desorbed into the water column from the resuspended sediment is negligible. They determined that contaminants were basically transferred to the water column attached to solids. They also reported that the reduction of 24 Received A'," 1120213 DCM-EC AManteo (Shallowbag) Bay Maintenance Dredging Project APTIM suspended solids concentration due to settling resulted in a decrease in contaminant concentrations. Metals, another possible contaminant within the sediments of Shallowbag Bay, are not necessarily fixed permanently by sediment, but may be recycled when they are resuspended during dredging operations via biological and chemical agents both within the sedimentary compartment and the water column. In aquatic systems, heavy metals are accumulated in sediments that can release from loosely bound fractions during dredging and disposal operations (Berenjkar et at, 2019). Availability of contaminant in the water column is greatly affected by the physical characteristics of the suspended sediments including particle size, distribution, total organic carbon, and mineral composition (Bridges et al., 2008). As described in the Sediment Analysis Report (Appendix D), the material to be dredged, as determined from recently obtained vibracores, can be described as four predominant types of sediments. The first type of sediment consisted of sand (SW) that was light olive brown (2.5Y-5/6) in color with 0.95 percent fines. The second type of sediment consisted of silty sand (SM) that was dark olive gray in color with 30.51 percent fines. The third type consisted of clayey silt (ML-CL) with pockets of fine to silty sand, mottled black in color (5Y-2.5/1) with 69.42 percent fines. The fourth type, the most prevalent type observed, consisted of clay (CL) was black in color (5Y-2.5/1) with 95.55 percent fines. The solubility, mobility, and bioavailability of sediment -bound metals can be increased by four major factors: (1) Lowering of pH; (2) changing of redox conditions; (3) formation of organic complexes; and (4) increasing salinity. While the first two factors are particularly important for on -land deposition of dredged materials, the effect of salinity is particularly important for resuspended cadmium -rich sediments in estuaries. Chemical extraction studies, which were carried out under carefully controlled conditions on both fresh and freeze-dried samples, indicate that aeration of anoxic sediments (e.g., on -land disposal) may both increase and decrease the mobility of heavy metals. Transformation from sulfidic or carbonatic associations to oxidic phases will reduce mobility of manganese, whereas the respective changes from moderately reducible forms to carbonatic and easily reducible phases will enhance the reactivity of zinc during oxidation of dredged material (Forstner et al., 1986). With this information in mind, the potential spread of contaminants during dredging operations would primarily be associated with the resuspension of sediments, particularly clay -sized and organic particles, during dredging operations. Unlike cutterhead pipeline dredges or hopper dredge operations, the clamshell bucket dredge is anticipated to result in a minimal amount of resuspension of sediments. It has been demonstrated that elevated suspended solids concentrations are generally limited to the immediate vicinity of the dredge and dissipate rapidly at the completion of the operation (Montgomery, 1984). In areas such as Shallowbag Bay and Doughs Creek, where there is relatively little current, the potential for sediment transport is limited. However, in areas such as Roanoke Sound where current is stronger, more potential for sediment redistribution and water column turbidity is likely. Designated channels can limit disturbance to sediments by creating deeper channels by which boaters can navigate without stirring up sediments. In theory, deep, well -marked navigation channels reduce the amount of traffic over shallow areas. The potential 25 Received P ," 1 1 2029 DMEC A Manteo (Shallowbag) Bay Maintenance Dredging Project APTIM of sediment disturbance is much greater if there are no navigation channels are available for the public to use. Channels do exist now, however, and many sections of the channels are five feet deep during times of low water. It is during these times that prop wash could affect the sediments. Therefore, deepening and marking channels may actually decrease the possibility of daily turbidity in the water column (Quible & Associates, 2005). In addition, impacts associated with resuspension and turbidity will be minimized because the dredging activity will be limited to 30 September through 1 April which corresponds with times of lower biological productivity within the project area. 4.7 Cultural Resources Cultural resources, such as archaeological or historic artifacts and structures, exist along portions of the North Carolina coastline including along Roanoke Island and the submerged bottoms within Shallowbag Bay. The federal statutes associated with the protection of these important cultural resources include Section 106 of the National Historic Preservation Act of 1966, as amended (PL 89-665); the National Environmental Policy Act of 1969; the Archaeological Resources Protection Act of 1987; the Advisory Council on Historic Preservation Procedures for the Protection of Historic and Cultural Properties (36 CFR Part 800); and the Abandoned Shipwreck Act of 1987. Roanoke Island has received considerable attention by historians due to the location of an early settlement by the English (aka the "Lost Colony"). In 1594, English settlers constructed a fort and a village of dwellings on the north end of Roanoke Island This settlement, the first attempted English colony in the New World, was periodically inhabited until the late 1580's when it was found mysteriously abandoned. Today, the only indication of the settlement's existence is the archeological remains of a small fortification at the site of the Fort Raleigh National Park (Harrington, 1962). The waters of Shallowbag Bay, meanwhile, were historically extremely shallow and restricted navigation to small shallow draft vessels and had only a minimal amount of maritime activity (Wilde-Ramsing et al., 1983). However, in 1870, maritime activities in this area increased dramatically with the formation of present day Dare County and the selection of Manteo as the county seat. The town grew around the mouth of Doughs Creek (across from the current berth of the Elizabeth II) to accommodate both the functions of the county government and the growing commercial fishing industry (which had accelerated with the advent of refrigeration in the 1870s (Stick, 1970). During this time period a harbor was constructed at Manteo and a boat basin was dredged and maintained. In addition, a 6' channel was dredged to provide dependable access to the main shipping route in Roanoke Sound. The primary activity associated with this proposed project involves dredging within the footprint of the previously dredged federal navigation channel. Because the submerged land within the footprint has been repeatedly disturbed in the past, no impacts to cultural resources associated with future dredging within this area are anticipated. The proposed activity, however, also includes dredging outside of the federal navigation channel in an area that will serve to connect the berth of the Elizabeth II to Range 1 just south of Doughs Creek. 26 Received v+9 11 2M DCM-EC At Manteo (Shallowbag) Bay Maintenance Dredging Project APTIM In 1982, the Underwater Archaeology Branch (UAB) of the North Carolina Department of Cultural Resources (NC DCR) performed a magnetometer reconnaissance survey and diving assessment in an attempt to identify historically and/or archaeologically significant cultural materials within four areas in proximity to the proposed project. These areas include the bridge crossing spanning Doughs Creek from Manteo to Festival Park, the canal access channel in Doughs Creek, the berthing basin for the Elizabeth II and channel in Doughs Creek, and the canal access channel in Shallowbag Bay (Wilde-Ramsing et al., 1983). Initially, a systematic survey of these areas were performed using a proton procession magnetometer to isolate magnetic disturbances that could be generated by cultural material. Following the magnetometer survey, a diving and probing search was conducted on isoloated magnetic targets to determine the source. The findings of the survey supported the UAB's preliminary predication based on current Environmental Review Procedures that no cultural evidence would be encountered from a period of history prior to the development of Manteo in 1870. With the exception of the remains of a sunken vessel located to the south of the Elizabeth II's birth (Underwater Site #OOOIROS), all magnetic disturbances identified during the survey were attributed to cultural debris of recent origin (20a' Century) and were determined historically and archaeologically insignificant (Wilde-Ramsing et al, 1983). The sunken vessel, recovered in the 1980's, was determined to be 24' shad boat fastened with iron nails and propelled by an internal combustion engine that showed signs of extensive burning. The vessel was recovered in the 1980's. According to the NCDCR the entire area that may warrant dredging in proximity to the Elizabeth U's berth was cleared for cultural resources concerns (N. Henry, 2019 personal communication). Therefore, the dredging within the footprint of the proposed new channel connecting the berth of the Elizabeth 11 to Range 1 will not impact any cultural resources. Another underwater investigation of magnetic anomalies within the project area was performed in 2007 by the Institute for International Maritime Research, Inc. The results of this shallow water survey and anomaly identification at Roanoke Island provided little new insight into the nature of material generating magnetic anomalies in both Roanoke Sound and Shallowbag Bay primarily due to challenging weather conditions that hampered the effort. Several anomalies were identified, however, they were identified as insignificant materials (Watts, 2008). The report, however, include a figure that depicted a large number of anomalies that were previously identified in an earlier magnetometer survey which have not been investigated further (Watts, personal comm. 2019) (Figure 8).

Anomalies identified during the 2006 Shallowbag Bay magnetic remote sensing investigation (Wafts, 2008). 4.8 Recreational Resources Unlike other harbors along the Outer Banks, Shallowbag Bay is typically protected from the brunt of passing hurricanes as it is sheltered by the barrier islands located just a couple miles away. In addition, it is bordered by the north and south facing shorelines of Roanoke Island giving the bay cove -like characteristics. This geography means that while there might be a strong wind affecting the oceanside and soundside beaches, the waters within Shallowbag Bay remain generally calm, and is therefore ideal for recreational boaters. The area is commonly used by 28 Received MAg11M') DCM-EC AManteo (Shallowbag) Bay Maintenance Dredging Project APTIM recreational boaters including motor boats, sailboats, and unmotorized vessels such as canoes and kayaks. Many of these boats utilized private docks located around the bay's borders while others utilize the three public boat ramp at Manteo for access to the water. Shallowbag Bay is proximate to the waters of Roanoke Sound and is not far from ocean access through Oregon Inlet approximately 12 miles to the south. The implementation of the proposed project is anticipated to positively impact recreational resource opportunities due to the improved navigability within Shallowbag Bay and the berth of the Elizabeth H. 4.9 Socioeconomic Resources Maintaining navigation through Shallowbag Bay is important to the local economy of the Town of Manteo and Dare County. Recreational and commercial boats utilize the bay as a conduit to Roanoke Sound and Oregon Inlet where they can access the Atlantic Ocean for fishing, SCUBA diving, and other recreational activities. Many of these boats are kept at one of the several marinas including the 75-slip Shallowbag Bay Marina and the 53-slip Manteo Waterfront Marina. Transient mariners who access the Town of Manteo through Shallowbag Bay utilize these marinas for overnight visits. These tourists visit Manteo's attractions, restaurants and, shops bringing in revenue to the local economy. Dockmaster Carl Jordan stated in 2018 that typically about 90 boars dock in the summer at the harbor per month. In 2017 only 60 boats entered the harbor (Hampton, 2018). Along with recreational vessels that rely on navigating through Shallowbag Bay to access the marinas along Manteo's waterfront, the Elizabeth II relies on safe passage through the bay so it can access haul out locations for maintenance and repairs. The Elizabeth II, a wooden vessel that was built in 1983 to represent the 16th Century ships that sailed to Roanoke Island in 1584-1587, is supposed to be hauled out every winter at the state ferry facility in Mains Harbor for repairs and maintenance (Hampton, 2018). But shoaling at the intersection of the Roanoke Sound and Shallowbag Bay has prevented the $670,000 ship from leaving its dock for several years and there is concern that she could significantly deteriorate. Should the boat become unusable as an educational tool at Festival Park, revenues associated with admission fees and tourism would be lost. The implementation of the proposed project is anticipated to positively impact socioeconomic resource opportunities due to the improved navigability within Shallowbag Bay for recreational and commercial vessels including the Elizabeth II. 5.0 Literature Cited Adriannse, L.A. and J.

Post Office Box 33726 Raleigh, North Carolina 27636-3726 IC ®li ��++pp�q IVI'E GUIDELINES FOR AVOIDING IMPACTS TO THE WEST INDIAN MANATEE Precautionary Measures for Construction Activities in North Carolina Waters The West Indian manatee (Trichechus manatus), also known as the Florida manatee, is a Federally -listed endangered aquatic mammal protected underthe Endangered Species Act of 1973, as amended (16 U.S.C. 1531 etseq.) and the Marine Mammal Protection Act of 1972, as amended (16 U.S.0 1461 etseq.). The manatee is also listed as endangered under the North Carolina Endangered Species Act of 1987 (Article 25 of Chapter 113 of the General Statutes). The U.S. Fish and Wildlife Service (Service) is the lead Federal agency responsible for the protection and recovery of the West Indian manatee under the provisions of the Endangered Species Act. Adult manatees average 10 feet long and weigh about 2,200 pounds, although some individuals have been recorded at lengths greater than 13 feet and weighing as much as 3,500pounds. Manatees are commonly found in fresh, brackish, or marine water habitats, including shallow coastal bays, lagoons, estuaries, and inland rivers of varying salinity extremes. Manatees spend much of their time underwater or partly submerged, making them difficult to detect even in shallow water. While the manatee's principal stronghold in the United States is Florida, the species is considered a seasonal inhabitant of North Carolina with most occurrences reported from June through October. To protect manatees in North Carolina, the Service's Raleigh Field Office has prepared precautionary measures for general construction activities in waters used by the species. Implementation of these measure will allow in -water projects which do not require blasting to proceed without adverse impacts to manatees. In addition, inclusion of these guidelines as conservation measures in a Biological Assessment or Biological Evaluation, or as part of the determination of impacts on the manatee in an environmental document prepared pursuant to the National Environmental Policy Act, will expedite the Service's review of the document for the fulfillment of requirements under Section 7 of the Endangered Species Act. These measures include: 1. The project manager and/or contractor will inform all personnel associated with the project that manatees may be present in the project area, and the need to avoid any harm to these endangered mammals. The project manager will ensure that all construction personnel know the general appearance of the species and their habit of moving about completely or partially submerged in shallow water. All construction personnel will be informed that they are responsible for observing water -related activities for the presence of manatees. 2. The project manager and/or the contractor will advise all construction personnel that there are civil and criminal penalties for harming, harassing, or killing manatees which are protected under the Marine Mammal Protection Act and the Endangered Species Act. 3. If a manatee is seen within 100 yards of the active construction and/or dredging operation or vessel movement, all appropriate precautions will be implemented to ensure protection of the manatee. These precautions will include the immediate shutdown of moving equipment if a manatee comes within 50 feet of the operational area of the equipment. Activities will not resume until the manatee has departed the project area on its own volition (i.e., it may not be herded or harassed from the area). 4. Any collision with and/or injury to a manatee will be reported immediately. The report must be made to the U.S. Fish and Wildlife Service (ph. 919.856.4520 ext. 16), the National Marine Fisheries Service (ph. 252.728.8762), and the North Carolina Wildlife Resources Commission (ph. 252.448.1546). 5. A sign will be posted in all vessels associated with the project where it is clearly visible to the vessel operator. The sign should state: CAUTION: The endangered manatee may occu rin these waters during the warmer months, primarily from June through October. Idle speed is required if operating this vessel in shallow water during these months. All equipment must be shutdown if a manatee comes within 50 feet of the vessel or operating equipment. A collision with and/or injury to the manatee must be reported immediatelyto the U.S. Fish and Wildlife Service (919-856-4520 ext. 16), the National Marine Fisheries Service (252.728.8762), and the North Carolina Wildlife Resources Commission (252.448.1546). 6. The contractor will maintain a log detailing sightings, collisions, and/or injuries to manatees during project activities. Upon completion of the action, the project manager will prepare a report which summarizes all information on manatees encountered and submit the report to the Service's Raleigh Field Office. 7. All vessels associated with the construction project will operate at "no wake/idle" speeds at all times while in water where the draft of the vessel provides less than a four foot clearance from the bottom. All vessels will follow routes of deep water whenever possible. 8. If siltation barriers must be placed in shallow water, these barriers will be: (a) made of material in which manatees cannot become entangled; (b) secured in a manner that they cannot break free and entangle manatees; and, (c) regularly monitored to ensure that manatees have not become entangled. Barriers will be placed in a manner to allow manatees entry to or exit from essential habitat.
