The Maine Department of Transportation (MDOT) has applied to the National Marine Fisheries Service (NMFS) for authorization to harass harbor seals, harp seals, gray seals, hooded seals, harbor porpoises, common dolphins, and Atlantic white-sided dolphins during bridge construction in Blue Hill, Maine. MDOT is repairing structural deficiencies in the Falls Bridge and seeks the IHA for anticipated harassment of marine mammals during pile-driving necessary to erect a temporary bridge between July 1, 2022, and June 30, 2023. NMFS is accepting comments through December 6, 2021.
