Biological Opinion Metlakatla Seaplane Facility Refurbishment Project

July 23, 2021

Endangered Species Act (ESA) Section 7(a)(2) Biological Opinion Metlakatla Seaplane Facility Refurbishment Project, Metlakatla, Alaska, NMFS Consultation Number: AKRO-2020-03066

In this document, the action agencies are the Federal Aviation Administration (FAA) and the NMFS Office of Protected Resources, Permits and Conservation Division (PR1). The Alaska Department of Transportation and Public Facilities (ADOT&PF) has been designated as the non-federal representative for FAA. FAA, in cooperation with the ADOT&PF, is proposing maintenance improvements to the existing Metlakatla Seaplane Facility. PR1 proposes to authorize Marine Mammal Protection Act (MMPA) Level B take (i.e., take by harassment) of one ESA-listed marine mammal species: humpback whale (Megaptera novaeangliae), and seven non-listed marine mammal species: Steller sea lion (Eumetopias jubatus), harbor seal (Phoca vitulina), harbor porpoise (Phocoena phocoena), Dall’s porpoise (Phocoenoides dalli), killer whale (Orcinus orca), Pacific white-sided dolphin (Lagenorhynchus obliquidens), and minke whale (Balaenoptera acutorostrata) in conjunction with the action. No level A take has been proposed for humpback whales.

This project includes the removal of 11 existing steel piles (16-inch diameter) and installation of six (24 inch diameter) permanent steel piles to support replacement of the floating dock structure. Twelve (24 inch diameter) temporary steel piles will be installed to support pile installation and will be removed following the completion of pile installation. In addition, above-water construction will include repairs to the vehicle gangway and installation of an electrical lighting system for the approach and the new floating dock.
