ATONs can include a variety of visible structures such as buoys, daybeacons, lights, lightships, marks, or audible and electronic signals or devices such as radio beacons, fog signals, and other devices used to assist with coastal navigation. Mariners use ATONs to determine position or chart a safe course through coastal waters. ATONs can also be used to mark isolated danger/hazards, and/or navigational channels. The USCG is responsible for maintaining ATONs on US waters that are under federal jurisdiction. The term ATON encompasses a wide range of floating and fixed objects mentioned above. A fixed object means one that is attached to the bottom or shore and typically consists of buoys and beacons. A buoy is a floating object that is anchored to the bottom, while a beacon is a permanent structure that is fixed to the seabed or land. Lighted beacons are called “lights” while unlighted beacons are called “daybeacons”. The proposed project involves repairs and replacement of two (2) daybeacons and seven (7) lights, and one (1) VAIS. The proposed repairs and replacements are required in order to maintain safe navigation of vessels off the coast of Massachusetts. 2.0 Proposed Project The following sections describe the one (1) existing ATON structure that requires complete replacement and three (3) ATON structures that involve removal. Work at these four (4) ATON structures involves impacts to areas subject to protection under the Massachusetts Wetland Protection Act (WPA) (M.G.L. c. 131, § 40) administered by 310 CMR 10.00 Wetlands Protection. The following four (4) structures require the submittal of a Notice of Intent (NOI) for impacts to resource areas associated with the complete replacement or removal of the existing structures: • Broadway Daybeacon 3, Falmouth, MA • Collier Ledge Isolated Danger VAIS, Barnstable, MA • Southwest Rock Daybeacon, Barnstable, MA • Saquatucket Harbor East Jetty Light 6, Harwich, MA The remaining six (6) structures included in the overall project do not require any in-water work or impacts to any jurisdictional resource areas. Therefore, a NOI is not required for the proposed repairs to the following structures: • Falmouth Inner Harbor Light 1, Falmouth, MA • Nantucket East Breakwater Light 3, Nantucket, MA • Nantucket Harbor Range Front Light, Nantucket, MA • Nantucket Harbor Range Rear Light, Nantucket, MA • Cape Cod Canal Eastern Entrance Range Front Light, Sandwich, MA • Cape Cod Canal Eastern Entrance Range Rear Light, Sandwich, MA UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION 2 The six (6) structures that do not require in-water work or impacts to jurisdictional areas are not discussed further in this submittal.

However, the nearshore area shall extend seaward only to that point where the land is 30 feet below the level of the ocean at mean low water for municipalities bordering Buzzard's Bay and Vineyard Sound (west of a line between West Chop, Martha's Vineyard and Nobska Point, Falmouth), 40 feet below the level of the ocean at mean low water UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION 4 for Provincetown's land in Cape Cod Bay, and 50 feet below the level of the ocean at mean low water for Truro's and Wellfleet's land in Cape Cod Bay.” The following four replacement USCG ATON structures are located within Land under the Ocean: • Broadway Daybeacon 3 • Collier Ledge Isolated Danger VAIS • Southwest Rock Daybeacon • Saquatucket Harbor EAST Jetty Light 6 3.2 Rocky Intertidal Shores Rocky Intertidal Shores are defined by 310 CMR 10.31(2) as, “naturally occurring rocky areas, such as bedrock or boulder strewn areas between the mean high water line and the mean low water line.” There are no structures located within rocky intertidal chores. 3.3 Land Containing Shellfish Land Containing Shellfish is defined by 310 CMR 10.34(2) as, “land under the ocean, tidal flats, rocky intertidal shores, salt marshes and land under salt ponds when any such land contains shellfish.” The regulations further define the term “shellfish” as the following species: Bay scallop (Argopecten irradians); Blue mussel (Mytilus edulis); Ocean quahog (Arctica islandica); American oyster (Crassostrea virginica); Quahog (Mercenaria merceneria); Razor clam (Ensis directus); Sea clam (Spisula solidissima); Sea scallop (Placopecten magellanicus); Soft shell clam (Mya arenaria). The Shellfish Suitability Areas GIS data layer (May 2011), delineates areas that are believed to be suitable for shellfish based on the expertise of the Massachusetts Division of Marine Fisheries (Marine Fisheries) and local Shellfish Constables, input from commercial fishermen, and information contained in maps and studies of shellfish in Massachusetts. The areas covered include sites where shellfish have been observed since the mid-1970’s,but may not currently support any shellfish. Therefore, these maps represent potential habitat areas. Based on the Shellfish Suitability Areas GIS data layer, Saquatucket Harbor East Jetty Light 6 is located within an area identified as potentially suitable for shellfish, particularly American oyster (Figure 3-8). Formal dive surveys have not been conducted to confirm the presence or absence of shellfish. However, given the relatively small area and nature of the proposed impacts associated with each of the ATON replacements, impacts to shellfish populations located within the vicinity of the ATON structure is assumed to be minimal. Therefore, the proposed project is not anticipated to impact the Land Containing Shellfish Resource Area. UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION 5 3.4 Land Under the Ocean that Underlie an Anadromous/Catadromous Fish Run Banks of or Land under the Ocean, Ponds, Streams, Rivers, Lakes, or Creeks that Underlie an Anadromous/Catadromous Fish Run is defined by 310 CMR 10.35(2) as, “that area within estuaries, ponds, streams, creeks, rivers, lakes or coastal waters, which is a spawning or feeding ground or passageway for anadromous or catadromous fish and which is identified by the Division of Marine Fisheries or has been mapped on the Coastal Atlas of the Coastal Zone Management Program. Such fish runs shall include those areas which have historically served as fish runs and are either being restored or are planned to be restored at the time the Notice of Intent is filed. For the purposes of 310 CMR 10.21 through 10.37, such fish runs shall extend inland no further than the inland boundary of the coastal zone.” Anadromous fish “means fish that enter fresh water from the ocean to spawn, such as alewives, shad and salmon”, while Catadromous Fish “means fish that enter salt water from fresh water to spawn, such as eels.” The four replacement USCG ATON structures are located in the vicinity of Woods Hole and north Nantucket Sound. Various species of anadromous and catadromous fish have the potential to be found within the project area at various times of year and life cycle stages. However, none of the replacement structures are located within an area that meets the definition of an Anadromous / Catadromous Fish Run as defined by 310 CMR 10.35(2). Appropriate BMPs (outlined in the sections below) will be implemented throughout the duration of construction in order to avoid or minimize impacts to fish and other wildlife. In addition, impacts from the proposed project are limited to the demolition or replacement of existing structures. Impacts will be located within the same footprint of the existing structures and are localized and short term in nature. The proposed project could cause minor, short-term changes in behavior due to construction activities (e.g., pile driving); however, with the implementation of BMPs, physiological impacts are not anticipated. Overall, the proposed project is not anticipated to result in adverse impacts to any anadromous or catadromous fish or fish runs. 4.0 Proposed ATON Demolition/Replacement Structures The following sections describe the existing conditions, resource areas, rare species, proposed actions, and impacts associated with the four (4) ATON structure demolitions/replacement. Each section corresponds to a different structure and Massachusetts City/Town.

The structure is a steel monopile braced with two steel batter piles. The foundation is in critical condition. The steel pipe pile is listing approximately 20 degrees to the east and is buckled at the approximate high-water line. The adjacent batter piles are listing and buckled. The piles exhibit moderate to major corrosion in the splash zone. The piles’ ring brace has failed at its connections to the piles. The optics platform is in critical condition. The optics platform is inaccessible due to the damage of the substructure. The lower half of the ladder is missing. No lighting equipment exists. The dayboards appear to have no significant deterioration.

No additional resource areas subject to jurisdiction under the WPA are located in the vicinity of the proposed project. Water depths in the vicinity of the structure vary from approximately 0’-2” (MLW) to 1’-11” (MHW). UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION FALMOUTH, MA Broadway Daybeacon 3 7 4.1.3 Rare, Threatened, and Endangered Species The Broadway Daybeacon 3 is located within MA Natural Heritage & Endangered Species Program (NHESP) Priority and Estimated Habitat polygons PH 887/EH 692. These polygons encompass Buzzards Bay and waters surrounding Woods Hole (see Figure 3-1). A Request for State-listed Species Information was submitted to the NHESP. According to the NHESP Response letter dated June 11, 2024 (File name IR- 85921, Appendix A) the project area or a portion thereof is located within the current Massachusetts Natural Heritage Atlas. The following state-listed species are mapped for both Priority (PH) and Estimated Habitat (EH): Roseate tern (Sterna dougallii) – endangered, least tern (Sternula antillarum) – special concern, and Common tern (Sterna hirundo) - special concern. The project is being submitted concurrently to NHESP as a Streamlined Massachusetts Endangered Species Act/Wetlands Protection Act Review. The project is located within the known and expected range of federally listed Atlantic sturgeon, shortnose sturgeon, sea turtles, and Atlantic large whales. 4.1.4 Proposed Action The proposed project involves a complete replacement of the entire ATON structure. A barge will be mobilized to the project site from which the majority of the work and staging will be completed. The existing structure will be demolished. Rock sockets will be drilled into the bedrock to install three 24” steel piles. The steel piles will be installed and the annulus between the rock and pile will be grouted. The remaining components of the structure will then be installed. The following Best Management Practices (BMPs) will be implemented during replacement of the Broadway Daybeacon 3 in order to minimize and avoid potential impacts to fish and wildlife in the vicinity of the proposed project. 1) For work that will involve pile driving, the following measures must be implemented: • Impact pile driving shall be limited to seating piles and shall commence with an initial set of three strikes by the hammer at 40% energy, followed by a one-minute wait period, then two subsequent 3-strike sets at 40% energy, with one minute waiting periods, before initiating continuous impact driving. • Vibratory pile driving shall be initiated for 15 seconds at reduced energy followed by a one minute waiting period. This sequence of 15 seconds of reduced energy driving, one- minute waiting period shall be repeated two more times, followed immediately by pile- driving at full rate and energy. • In addition to using a soft start at the beginning of the workday for pile driving as described above, a soft start must also be used at any time following a cessation of pile driving for a period of 30 minutes or longer. • Bubble curtains or cushions must be used to reduce sound pressure levels during vibratory or impact hammer pile driving. 2) For work that will involve pile removal, the following measures must be implemented: UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION FALMOUTH, MA Broadway Daybeacon 3 8 • Piles must be completely removed, cut and/or driven to 3 feet below the substrate to prevent interference with navigation, and existing creosote piles shall be completely removed if practicable. • In areas of fine-grained substrates, piles must be removed by the direct, vibratory or clamshell pull method to minimize sedimentation and turbidity impacts and prevent interference with navigation from cut piles. • Removed piles shall be disposed of in an upland location landward of MHW or OHW and not in wetlands, tidal wetlands or mudflats. 3) Shallow draft vessels that maximize the navigational clearance between the vessel and the ocean floor will be used where possible. 4) Vessels will operate at speeds of less than 10 knots. A lookout will be posted and measures taken to slow down and avoid any whales or sea turtles spotted. 5) The osprey nest located on Broadway Daybeacon 3 will be removed when the nest is inactive (likely between August and February). A nest is considered inactive when there no eggs or young in the nest. If construction does not commence immediately after removal of the inactive nest, temporary exclusion measures must be installed to prevent nesting from occurring prior to construction. 4.1.5 Impacts The proposed project is anticipated to result in approximately 189 square feet (SF) of permanent impacts to the Land Under the Ocean resource area. The impacts are associated with the removal of existing steel king pile and two batter piles, and the drilling and installation of three new steel batter piles. The proposed project is not anticipated to result in any additional impacts to other resource areas subject to jurisdiction under the WPA. 4.1.6 Regulatory Compliance and MA WPA Performance Standards The general performance standards are requirements for activities in or affecting the areas subject to protection under the WPA and are established by 310 CMR 10.00. The performance standards for Land under the Ocean are provided in 310 CMR 10.25(3) through (7). The following provides a summary of how the performance standards have been interpreted to protect the characteristics and resources of Land Under the Ocean to the maximum extent practicable. 310 CMR 10.25 Land under the Ocean (3) Improvement dredging for navigational purposes affecting land under the ocean shall be designed and carried out using the best available measures so as to minimize adverse effects on such interests caused by changes in: a) bottom topography which will result in increased flooding or erosion caused by an increase in the height or velocity of waves impacting the shore; UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION FALMOUTH, MA Broadway Daybeacon 3 9 The Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable) are remnant mounds of riprap that had been placed to support navigational aids that are no longer in service. Both riprap mounds will be removed permanently to below MLLW. The minimal footprint of rock to be removed and distance offshore make it unlikely that the project would result in increased wave heights or velocities that would result in increased flooding or erosion. b) sediment transport processes which will increase flood or erosion hazards by affecting the natural replenishment of beaches; The proposed project is not anticipated to affect sediment transport processes that would increase flood or erosion hazards by affecting the natural replenishment of beaches. c) water circulation which will result in an adverse change in flushing rate, temperature, or turbidity levels; or The proposed project is not anticipated to result in water circulation resulting in an adverse change in flushing rate, temperature, or turbidity levels. d) marine productivity which will result from the suspension or transport of pollutants, the smothering of bottom organisms, the accumulation of pollutants by organisms, or the destruction of marine fisheries habitat or wildlife habitat. The proposed project is not anticipated to result in impacts to marine productivity including impacts resulting from the suspension or transport of pollutants, the smothering of bottom organisms, the accumulation of pollutants by organisms, or the destruction of marine fisheries or wildlife habitat. (4) Maintenance dredging for navigational purposes affecting land under the ocean shall be designed and carried out using the best available measures so as to minimize adverse effects on such interests caused by changes in marine productivity which will result from the suspension or transport of pollutants, increases in turbidity, the smothering of bottom organisms, the accumulation of pollutants by organisms, or the destruction of marine fisheries habitat or wildlife habitat. The Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable) are remnant mounds of riprap that had been placed to support navigational aids that are no longer in service. Both riprap mounds will be removed permanently to below MLLW. Removing the existing piles of rocks will result in minor, short-term increases in turbidity. However, the coarse nature of the material and minimal footprint of rock to be removed will minimize adverse impacts. Appropriate BMPs designed to minimize adverse effects will be implemented throughout the duration of construction. (5) Projects not included in 310 CMR 10.25(3) or (4) which affect nearshore areas of land under the ocean shall not cause adverse effects by altering the bottom topography so as to increase storm damage or erosion of coastal beaches, coastal banks, coastal dunes, or salt marshes. UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION FALMOUTH, MA Broadway Daybeacon 3 10 The proposed project is not anticipated to result in changes to the bottom topography, and therefore, is not anticipated to result in an increase in storm damage or erosion of coastal beaches, coastal banks, coastal dunes, or salt marshes (6) Projects not included in 310 CMR 10.25(3) which affect land under the ocean shall if water-dependent be designed and constructed, using best available measures, so as to minimize adverse effects, and if non-water-dependent, have no adverse effects, on marine fisheries habitat or wildlife habitat caused by: a) alterations in water circulation; The proposed project is not anticipated to result in alteration in water circulation that would cause adverse effects. The project involves an in-kind of replacement of an existing structure and permanent removal of existing structures. The removal of the Saquatucket Harbor East Jetty Light 6 (Harwich) and Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable) remnant riprap mounds will result minor changes in water circulation; however, these changes will be located well offshore and will not result in any adverse effects. b) destruction of eelgrass (Zostera marina) or widgeon grass (Ruppia maritima) beds; There are no MassDEP mapped or observed eelgrass or widgeon grass beds located in the vicinity of the proposed project. The proposed project is not anticipated to result in the destruction of eelgrass or widgeon grass beds. c) alterations in the distribution of sediment grain size; The proposed project is not anticipated to result in alterations in the distribution of sediment grain size. d) changes in water quality, including, but not limited to, other than natural fluctuations in the level of dissolved oxygen, temperature or turbidity, or the addition of pollutants; or The proposed project is not anticipated to result in adverse effects to water quality. The proposed project will result in temporary turbidity releases associated with in-water work. However, these impacts will be short term and temporary in nature. e) alterations of shallow submerged lands with high densities of polychaetes, mollusks or macrophytic algae. The proposed project is not anticipated to result in any alteration to shallow submerged lands with high densities of polychaetes, mollusks, or macrophytic algae. No Shellfish Suitability Areas have been identified in the vicinity of the project area. The only proposed alterations to submerged lands entail the removal of riprap that had been placed to support navigational aids that are no longer in service at Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable). Both riprap mounds will be removed permanently to below MLLW. High densities of polychaetes, mollusks, and algae have not been observed on the riprap.

The performance standards for Land under the Ocean are provided in 310 CMR 10.25(3) through (7). The following provides a summary of how the performance standards have been interpreted to protect the characteristics and resources of Land Under the Ocean to the maximum extent practicable. 310 CMR 10.25 Land under the Ocean (3) Improvement dredging for navigational purposes affecting land under the ocean shall be designed and carried out using the best available measures so as to minimize adverse effects on such interests caused by changes in: i) bottom topography which will result in increased flooding or erosion caused by an increase in the height or velocity of waves impacting the shore; The Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable) are remnant mounds of riprap that had been placed to support navigational aids that are no longer in service. Both riprap mounds will be removed permanently to below MLLW. The minimal footprint of rock to be removed and distance offshore make it unlikely that the project would result in increased wave heights or velocities that would result in increased flooding or erosion. j) sediment transport processes which will increase flood or erosion hazards by affecting the natural replenishment of beaches; The proposed project is not anticipated to affect sediment transport processes that would increase flood or erosion hazards by affecting the natural replenishment of beaches. k) water circulation which will result in an adverse change in flushing rate, temperature, or turbidity levels; or The proposed project is not anticipated to result in water circulation resulting in an adverse change in flushing rate, temperature, or turbidity levels. l) marine productivity which will result from the suspension or transport of pollutants, the smothering of bottom organisms, the accumulation of pollutants by organisms, or the destruction of marine fisheries habitat or wildlife habitat. The proposed project is not anticipated to result in impacts to marine productivity including impacts resulting from the suspension or transport of pollutants, the smothering of bottom organisms, the accumulation of pollutants by organisms, or the destruction of marine fisheries or wildlife habitat. (4) Maintenance dredging for navigational purposes affecting land under the ocean shall be designed and carried out using the best available measures so as to minimize adverse effects on such interests caused by changes in marine productivity which will result from the suspension or transport of UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION BARNSTABLE, MA Southwest Rock Daybeacon 20 pollutants, increases in turbidity, the smothering of bottom organisms, the accumulation of pollutants by organisms, or the destruction of marine fisheries habitat or wildlife habitat. The Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable) are remnant mounds of riprap that had been placed to support navigational aids that are no longer in service. Both riprap mounds will be removed permanently to below MLLW. Removing the existing piles of rocks will result in minor, short-term increases in turbidity. However, the coarse nature of the material and minimal footprint of rock to be removed will minimize adverse impacts. Appropriate BMPs designed to minimize adverse effects will be implemented throughout the duration of construction. (5) Projects not included in 310 CMR 10.25(3) or (4) which affect nearshore areas of land under the ocean shall not cause adverse effects by altering the bottom topography so as to increase storm damage or erosion of coastal beaches, coastal banks, coastal dunes, or salt marshes. The proposed project is not anticipated to result in changes to the bottom topography, and therefore, is not anticipated to result in an increase in storm damage or erosion of coastal beaches, coastal banks, coastal dunes, or salt marshes (6) Projects not included in 310 CMR 10.25(3) which affect land under the ocean shall if water-dependent be designed and constructed, using best available measures, so as to minimize adverse effects, and if non-water-dependent, have no adverse effects, on marine fisheries habitat or wildlife habitat caused by: k) alterations in water circulation; The proposed project is not anticipated to result in alteration in water circulation that would cause adverse effects. The project involves an in-kind of replacement of an existing structure and permanent removal of existing structures. The removal of the Saquatucket Harbor East Jetty Light 6 (Harwich) and Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable) remnant riprap mounds will result minor changes in water circulation; however, these changes will be located well offshore and will not result in any adverse effects. l) destruction of eelgrass (Zostera marina) or widgeon grass (Ruppia maritima) beds; There are no MassDEP mapped or observed eelgrass or widgeon grass beds located in the vicinity of the proposed project. The proposed project is not anticipated to result in the destruction of eelgrass or widgeon grass beds. m) alterations in the distribution of sediment grain size; The proposed project is not anticipated to result in alterations in the distribution of sediment grain size. n) changes in water quality, including, but not limited to, other than natural fluctuations in the level of dissolved oxygen, temperature or turbidity, or the addition of pollutants; or UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION BARNSTABLE, MA Southwest Rock Daybeacon 21 The proposed project is not anticipated to result in adverse effects to water quality. The proposed project will result in temporary turbidity releases associated with in-water work. However, these impacts will be short term and temporary in nature. o) alterations of shallow submerged lands with high densities of polychaetes, mollusks or macrophytic algae. The proposed project is not anticipated to result in any alteration to shallow submerged lands with high densities of polychaetes, mollusks, or macrophytic algae. No Shellfish Suitability Areas have been identified in the vicinity of the project area. The only proposed alterations to submerged lands entail the removal of riprap that had been placed to support navigational aids that are no longer in service at Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable). Both riprap mounds will be removed permanently to below MLLW. High densities of polychaetes, mollusks, and algae have not been observed on the riprap. (7) Notwithstanding the provisions of 310 CMR 10.25(3) through (6), no project may be permitted which will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate species, as identified by procedures established under 310 CMR 10.37. The proposed project is located within NHESP mapped Estimated Habitats of Rare Wildlife and Priority Habitats for roseate tern, common tern, and least tern. The proposed project will result in an adverse effect on these species, nor other rare vertebrate or invertebrate species. The Broadway Daybeacon (Falmouth) will be replaced in-kind in the same footprint. The structure is approximately 1.5 miles from shore. The Saquatucket Harbor East Jetty Light 6 (Harwich) is an existing timber pile structure that will be removed permanently. The Collier Ledge Isolated Danger VAIS and Southwest Rock Daybeacon (Barnstable) are remnant mounds of riprap that had been placed to support in-service navigational aids.

UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION HARWICH, MA Saquatucket Harbor East Jetty Light 6 22 4.4 Harwich, MA - Saquatucket Harbor East Jetty Light 6 4.4.1 Existing Conditions Saquatucket Harbor East Jetty Light 6 (41° 39’ 48.640”N, 070° 03’ 39.570”W) is an obsolete ATON near the end of the east jetty of the port of Harwich, Massachusetts in the Nantucket Sound. The structure is a braced timber pile structure with a timber superstructure. The ATON has been superseded by a nearby replacement aide. The timber piles are in CRITICAL condition. The 16-inch timber king pile and four 16- inch timber piles have widespread severe fungal decay with 100 percent section loss. The deterioration extends from the water line for the entire height of the piles. The lower steel cable wrap is missing. The remaining existing steel cable wraps have severe corrosion and are severed. The mid-height timber bracing exhibits moderate weathering. All bolted connections have moderate coating loss and corrosion. The seabed is comprised of a sandy bottom. The optics platform is in poor condition. The timber optics platform exhibits widespread moderate fungal decay. All bolted connections have moderate coating loss and corrosion. The timber decking exhibits widespread checking and major fungal decay. A thick layer of guano is present on the deck. The galvanized steel handrails have no significant deterioration. The lower extent of the access ladder is broken due to corrosion. No navigational aid equipment exists on the structure.

No additional resource areas subject to jurisdiction under the WPA are located in the vicinity of the proposed project. Water depths in the vicinity of the structure vary from approximately 0’- 3” (MLW) to 3’-5” (MHW). 4.4.2.1 Land Containing Shellfish Based on the Shellfish Suitability Areas GIS data layer, Saquatucket Harbor East Jetty Light 6 is located within an area identified as potentially suitable for shellfish, particularly American oyster (Figure 3-8). Formal dive surveys have not been conducted to confirm the presence or absence of shellfish. However, given the relatively small area and nature of the proposed impacts associated with each of the ATON replacements, impacts to shellfish populations located within the vicinity of the ATON structures is assumed to be minimal. Therefore, the proposed project is not anticipated to impact the Land Containing Shellfish Resource Area. 4.4.3 Rare, Threatened, and Endangered Species Saquatucket Harbor East Jetty Light 6 is located within NHESP Priority and Estimated Habitat polygons PH 2156/EH 693. These polygons encompass the northern portion of Nantucket Sound (see Figure 2-8). A Request for State-listed Species Information was submitted to the NHESP. According to the NHESP Response letter dated June 11, 2024 (File name IR-85921, Appendix A) the project area or a portion thereof is located within the current Massachusetts Natural Heritage Atlas. The following state-listed species are mapped for both Priority (PH) and Estimated Habitat (EH): Roseate tern (Sterna dougallii) – endangered, least tern (Sternula antillarum) – special concern, and Common tern (Sterna hirundo) - special concern. The project is being submitted concurrently to NHESP as a Streamlined Massachusetts Endangered Species Act/Wetlands Protection Act Review. The project is located within the known and expected range of federally listed Atlantic sturgeon, shortnose sturgeon, sea turtles, and Atlantic large whales. 4.4.4 Proposed Action The proposed project involves the demolition and removal of the ATON structure. A barge will be mobilized to the project site from which the majority of the work and staging will be completed. The existing timber ATON structure will be demolished in its entirety. The following Best Management Practices (BMPs) will be implemented during construction of Saquatucket Harbor East Jetty Light 6 in order to minimize and avoid potential impacts to fish and wildlife in the vicinity of the proposed project. 1) For work that will involve pile removal, the following measures must be implemented: UNITED STATES COAST GUARD WOODS HOLE ATON REPAIR PROJECT MA WPA NOTICE OF INTENT SUPPLEMENTAL PROJECT DESCRIPTION HARWICH, MA Saquatucket Harbor East Jetty Light 6 24 • Piles must be completely removed, cut and/or driven to 3 feet below the substrate to prevent interference with navigation, and existing creosote piles shall be completely removed if practicable. • In areas of fine-grained substrates, piles must be removed by the direct, vibratory or clamshell pull method to minimize sedimentation and turbidity impacts and prevent interference with navigation from cut piles. • Removed piles shall be disposed of in an upland location landward of MHW or OHW and not in wetlands, tidal wetlands or mudflats. 2) Shallow draft vessels that maximize the navigational clearance between the vessel and the ocean floor will be used where possible. 3) Vessels will operate at speeds of less than 10 knots. A lookout will be posted and measures taken to slow down and avoid any whales or sea turtles spotted. 4) The cormorant nests located on Saquatucket Harbor East Jetty Light 6 will be removed when the nests are inactive (likely between July and March). A nest is considered inactive when there no eggs or young in the nest. If construction does not commence immediately after removal of the inactive nests, temporary exclusion measures must be installed to prevent nesting from occurring prior to construction. 4.4.5 Impacts The proposed replacement of the Saquatucket Harbor East Jetty Light 6 is located within NHESP Priority and Estimated Habitat polygons PH 2156/EH 693. These polygons encompass the northern portion of Nantucket Sound. (see Figure 3-8). The proposed project is anticipated to result in approximately 110 square feet (SF) of permanent impacts to the Land Under the Ocean resource area. The impacts are associated with the removal of three existing timber piles. The proposed project is not anticipated to result in any additional impacts to other resource areas subject to jurisdiction under the WPA. The proposed project is limited to demolition and removal of the existing structure. 4.4.6 Regulatory Compliance and MA WPA Performance Standards The general performance standards are requirements for activities in or affecting the areas subject to protection under the WPA and are established by 310 CMR 10.00.
