H.R. 4266 would confirm the boundary of Acadia National Park in Maine. The National Park Service (NPS), which manages the park, administratively adjusted the boundary in 2015 when the agency accepted the donation of 1,441 acres of land for inclusion within the park. The bill also would permanently authorize that park’s advisory commission and require the NPS to allow traditional harvesting of marine species within and near park boundaries in accordance with the laws of the State of Maine. Finally, the bill would require the NPS to convey a 0.29-acre parcel of land located within the park to the Town of Bar Harbor.
