Rodney French Blvd 92 Fort Avenue 30 Emerson Avenue New Bedford, MA 02744 Salem, MA 01970 Gloucester, MA 01930 February 14, 2025 Yarmouth Conservation Commission 1146 Route 28 South Yarmouth, MA 02664 Dear Commissioners: The Massachusetts Division of Marine Fisheries (MA DMF) has reviewed the Notice of Intent (NOI) by Rosangela Caloiero to remove an existing pier, gangway, and float and construct a new pier, gangway, and floats in a new footprint within the Bass River at 59 Oyster Cove Road in the Town of Yarmouth. The project was reviewed with respect to potential impacts to marine fisheries resources and habitat. The project site lies within mapped shellfish habitat for northern quahog (Mercenaria mercenaria). Waters within the project site have habitat characteristics suitable for this species. No shellfish were found during a shellfish survey conducted by the BSC Group on April 1, 2024. Land containing shellfish is deemed significant to the interest of the Wetlands Protection Act (310 CMR 10.34) and the protection of marine fisheries. The project site overlies salt marsh vegetation. Salt marsh provides a variety of ecosystem services, including habitat and energy sources for many fish and invertebrate species [1-2]. The Bass River has been identified by MA DMF as diadromous fish passage, migration, and/or spawning habitat for alewife (Alosa pseudoharengus), white perch (Morone americana), and American eel (Anguilla rostrata) [3]. The Bass River acts as winter flounder (Pseudopleuronectes americanus) spawning habitat. Winter flounder enter the area and spawn from January through May; demersal eggs hatch approximately 15 to 20 days later. The Atlantic States Marine Fisheries Commission has designated winter flounder spawning habitat as a “Habitat Area of Particular Concern” (HAPC). In the previous stock assessment, the winter flounder stock was classified as overfished with spawning stock biomass in 2019 estimated to be only 32% of the biomass target [4]. Spawning stock biomass in 2021 was estimated to be 101% of the biomass target based on a new recruitment stanza focusing only on the past twenty years [5]. Given the new status of the winter flounder stock, every effort should be made to protect the species and its spawning habitat. MA DMF offers the following comments for your consideration: 2 • Repair of the structure should be within the same footprint as the existing structure. • Grounded floats can disturb bottom sediments, resulting in turbidity and direct impacts to benthic habitat. To minimize impacts, MA DMF recommends that the bottom of a proposed float be at least 2.5 feet (30 inches) above the substrate over mapped shellfish habitat, at MLW [6]. The entire float as proposed does not maintain this minimum clearance at MLW. MA DMF recommends installing pile-supported float stops to maintain a 2.5 foot clearance above the substrate at MLW. • Any piles that will be removed should be fully removed from the substrate - rather than cut at the base – since the area is suitable shellfish habitat [6]. • Any activities requiring a barge should be restricted to 2 hours before and after high tide to prevent barge grounding in mapped shellfish habitat. • Fuel spills from refueling of construction equipment will adversely impact sensitive resource areas. Impacts to resource areas can be avoided by prohibiting all land-based equipment from being refueled on-site. If equipment is refueled on-site, adequate containment and clean up material should be required to minimize impacts.
