PLEASANT POINT (AP) – Four Passamaquoddy tribal members signaled their intent to file a lawsuit claiming a proposed liquefied natural gas terminal on Passamaquoddy Bay would be a threat to endangered right whales.

The tribal members contend the U.S. Department of the Interior failed to consult with the National Marine Fisheries Service before approving a lease agreement for the developer of a liquefied natural gas project.

Because of that, the lease agreement violates the Endangered Species Act, the four tribal members said in their complaint.

According to the complaint, right whales, humpback whales and fin whales spend parts of the year in Passamaquoddy Bay. Ship strikes and entanglement in fishing gear are the most serious threats to right whales and humpbacks, it said.

Last year, the Passamaquoddy Tribe entered into a lease agreement with Oklahoma-based Quoddy Bay LLC to build an LNG terminal on Indian land.
